Description

Procedure and device for the use of solar energy

The present invention relates to a device and a method for the use of solar energy.

The sun radiates over every square meter of the earth's surface with a perpendicular incidence of approximately one kilowatt of energy. A large number of different procedures and devices are known for the use of solar energy irradiated by the sun.

In photovoltaic technology, sunlight becomes directly current. The costs of this procedure, however, are very high, currently a square meter of photovoltaic solar cells costs approximately € 700. The procedure has an energy efficiency of 20%.

An alternative approach lies in the fact that the energy radiated by the sun is used for heat generation. In this case some procedures and devices are known in which sunlight is concentrated by means of mirrors that can be oriented.

The heat to be achieved in this way serves, for example, for heating an oil or for heating a liquid salt. The oil or salt heats water to make water vapor. With the generated water vapor, a steam turbine is activated for the generation of current by means of a current generator. This approach is technologically feasible, although it is comparatively complex and expensive.

Another approach lies in the fact of providing parabolic mirror installations, in which a sufficiently large closed mirror surface is oriented towards the sun. This orientation is carried out by means of the tilting tilt of the installation of the parabolic mirror, so that a two-axis control is necessary. An installation of this type generally has a high weight, as a consequence of the large surface of the mirror, so that only with great difficulties can it be oriented towards the sun with sufficient precision. The focus of the system shifts with the height of the sun, which makes it difficult to use sunbeams in beams as thermal energy. An example of such a system is a "solar dish", as described, for example, at http://www.solarpaces.org/resources/technologies.html.

A simpler orientation can be achieved with groove mirror systems, since these only have to be moved around an axis. Groove mirrors heat a tube, which runs in its focus line. In the technical embodiment, however, a problem arises in that pipe systems have to be adjusted, heated and protected against thermal losses, which makes the installations, again, expensive. An example of such a system is the Andasol project (http://ww.solarmillennium.de/).

In the so-called “solar tower” concept, a large number of mirrors are oriented to a common point at the tip of the “solar tower”. In this case, again, each of the mirrors has to be individually controlled by means of two axes, which, seeing the precision required in this case makes the procedure expensive (see, for example, http: // www .bmu.de / pressemitteilungen / pressemitteilungen_ab_22112005 / pm / 37405.pho). The price of such an installation has a value of approximately € 1,100 per square meter of mirror surface, and with that, with an energy efficiency of approximately 10%, it is just above the price for photovoltaic technology.

Another example for a so-called "solar tower" concept is known from document FR 2 354 590. The heliostat described herein has a main axis of rotation, which with the corresponding auxiliary means can make a slow movement around the axis itself to follow the height of the sun. The reflectors, respectively, are fixed on auxiliary rotation axes, which are arranged perpendicularly with respect to the main axis, and which can carry out a movement around the main axis with corresponding auxiliary means. Also in this case it is necessary to control the individual mirror through two axes.

A need for the orientation of mirror systems for the concentration of sunlight derives from the fact that, seen from the ground, the sun apparently makes a flat circular path through the earth. The plane of this circular path can be described in this case by means of a unit vector that is perpendicular on this plane. As a consequence of the inclination of the earth's axis with respect to the orbit, the direction of this unit vector is modified over a year, which has the effect that the meridian height of the sun, that is, the apparent height of the sun Above the horizon, it varies throughout the year.

Known devices and procedures for the use of solar energy are constructively expensive, and are partly expensive in their acquisition and operation.

The aim of the present invention, therefore, is to provide an alternative device and an alternative method for the use of solar energy, with which the problems of known devices and procedures are avoided, or at least reduced.

This objective is achieved by means of a device for the use of solar energy with the characteristics as defined in claim 1.

Likewise, this objective is achieved by means of a method for the use of solar energy with the characteristics as defined in claim 13.

The characteristics of the advantageous embodiments of the invention are defined in the dependent claims.

The device according to the invention first comprises an object and a number of reflectors to deflect the sun's rays towards the object. In this case, the reflectors are arranged so that they can be tilted, respectively, around an axis, to allow orientation of the reflectors according to the azimuth of the sun over a day, so as to adapt the reflectors to the apparent movement of the sun through the sky throughout the day. The corresponding axes are a constituent part of an arrangement of axes, which can be tilted for one year according to the meridian height of the sun. With this, the device can be adapted to the variation of the apparent solar path as a result of the angle between the earth's axis and the plane of rotation around the sun.

With the tilting of a mirror or reflector around an axis, which, like the unit vector mentioned above, is arranged perpendicularly to the plane of apparent path, the sun's rays that strike from the sun can be deflected on the same object to throughout the day In the case of a flat mirror, this object represents a surface that is approximately as large as the mirror, while with the correspondingly domed mirror the rays can also be reduced fundamentally to a point. The region to which the sun's rays are diverted is also commonly referred to as a "hot surface" or "hot spot."

If several reflectors are oriented in this way on a common object, then the incident sun rays can be concentrated in the object region, so that in this case there is an increased light intensity (yield per unit area ). In the process according to the invention, and in the device according to the invention, during the course of the day only one orientation of the reflectors is necessary according to the azimuth of the sun, that is, according to the direction (in the sky) from which the sun's rays affect, being able to realize this orientation with a tilting of the reflectors around the corresponding axis. The trajectory of the sun that is apparently modified throughout the year is taken into account thanks to the fact that the axis around which a reflector is tilted throughout the day is adapted by tilting an arrangement of axes that hosts this axis.

In a preferred embodiment, the arrangement of axes is configured such that the axis can be oriented by an inclination perpendicularly with respect to a plane of the sun's path. With an axis oriented perpendicularly to the sun's path, the sun's rays are deflected when the corresponding reflector is tilted essentially in the plane of the sun's path, so that in this way it is possible to achieve an especially simple guidance of the sun rays towards the object.

In another preferred embodiment of the present invention, the axis arrangement has a large number of axes, and is configured such that the axes can be inclined transversely with respect to a plane parallel to the axes. If the arrangement of axes is oriented during operation in such a way that the axes are arranged essentially next to each other in the east-west direction, in which the reflectors are opposed to the sun, then the axes can be adapted by by means of a transverse inclination with respect to the plane defined by means of the axes to the variation of the path plane of the apparent sun throughout the year.

In another embodiment of the present invention, the arrangement of axes has a large number of axes, and is configured such that the axes can be tilted in a plane parallel to the axes. An axis arrangement oriented along the east-west direction described above has a comparatively small effective surface area during the morning or afternoon. In the event that the effective surface area with respect to the sun has to be increased now during the afternoon or in the morning, or if an orientation in the east-west direction is not possible, then with an axis arrangement that allows an inclination of the axes in a plane parallel to the axes can also make an orientation of the arrangement of axes, in the extreme case, along a north-south direction, being able to adapt the inclination of the axes to the meridian height of the sun or well the inclination of the plane of the apparent sun's path.

Advantageously, the arrangement of axes can be configured in such a way that it allows an inclination of the axes both in a plane parallel to the axes and transversely to a plane of this type.

In another preferred embodiment of the present invention at least two reflectors can be swung around a common axis. Several reflectors can be assigned to a common axis, so that for the tilting of these reflectors, for example, only one drive of this axis is required. In case several reflectors are assigned to an axis, then these several reflectors, by means of the orientation of the common axis, can also be oriented in a common way, which reduces the cost of the apparatus.

According to another advantageous embodiment, the device according to the invention has a tilting drive system for the joint tilting of several reflectors around the corresponding axis, in particular with a first tilting transmission device, through which for each one of several reflectors can cause a predetermined tilt depending on the tilt drive system. If several reflectors are tilted in a common way by means of a tilting drive system, then the cost of the apparatus is reduced, and a control of the tilting of the various reflectors is allowed by means of a control of only the common tilt drive system. If there is a tilting transmission device, then several reflectors can also be operated by means of the tilting drive system, which must have a different tilting behavior respectively. With this it is possible to operate even all the reflectors of the device according to the invention by means of a single tilting drive system.

In another advantageous embodiment of the invention, the device has a tilting drive device assigned to a reflector or an axis for tilting the reflector or reflectors assigned to the axis. Furthermore, advantageously, a second tilting transmission device may be provided, by means of which for each of the reflectors a predetermined tilting can be caused depending on the tilting drive device. Instead of a common drive for a large number of reflectors, a single control of the tilting of the reflectors can also be provided through corresponding separate tilting drive devices. The tilting drive device can also be configured alternately to act on the reflectors of a common axis, so that the reflectors of this axis can be operated in a common and coordinated manner. With a second tilt transmission device, a different tilt of the commonly operated reflectors can be caused again.

In another embodiment of the present invention, a part of the reflectors is inclined relative to the corresponding axis. With inclined reflectors, the sun's rays can be deflected by removing them from the plane of the apparent sun's path, which makes it possible to coordinate several reflectors arranged one above the other in such a way that the sun's rays deflected through them affect an object, which does not It is parallel with the reflectors in a parallel plane with respect to the sun's path plane.

In another embodiment of the present invention, a part of the reflectors can be tilted relative to the corresponding axis. In this case, the fact that an inclination drive system is provided for the joint inclination of several reflectors with respect to their corresponding axis, in particular when a first inclination transmission device is provided, through which it is possible to provide cause a predetermined inclination for each of the various reflectors depending on the inclination drive system. Equally advantageous is the provision of an inclination drive device assigned to a reflector or an axis for the inclination of the reflector or reflectors assigned to the axis, in particular when a second inclination transmission device is also provided, through which a predetermined inclination can be caused for each of the reflectors depending on the inclination drive device.

An especially preferred embodiment of the present invention has a drive for tilting of several reflectors, in particular a transmission device is provided, through which a predetermined tilt can be caused for each of the several reflectors and / or an inclination depending on the drive.

According to another embodiment of the present invention, the object is coupled with the arrangement of axes in a fixed manner in relation to the arrangement of axes, so that an inclination of the arrangement of axes results in a corresponding movement of the object, which with this remains with respect to the reflectors in the same relative position. This does not require a special guidance of the object for adaptation to the trajectory plane of the modified sun throughout the year.

Alternatively, it can be provided that the object can move independently of the arrangement of axes, in particular by means of a special object drive.

According to a preferred embodiment of the present invention, the reflectors have mirrors, in particular with flat mirror surfaces. Flat or smooth mirrors are especially simple and suitable in their construction, and do not require any special processing to be used within the framework of the present invention.

According to another embodiment of the present invention, the reflectors are equipped to concentrate the deflected sun rays, the reflectors presenting, in particular, concave mirror surfaces.

Whereas in the case of flat mirror surfaces an increase in the intensity of the radiation that affects the object is achieved by means of the sum of the radiation diverted by several reflectors, with the sun rays concentrated by means of the reflectors You can get an additional increase in intensity.

According to another embodiment of the present invention, the object is configured to deflect the sun rays deflected thereon in a certain way. It is not necessary that the sunrays diverted to the object directly on the object be used for energy conversion, instead, it is also possible, for example, to combine several devices according to the invention, the corresponding objects being configured of such that they radiate a common "hot spot". If, in addition, for example, a desired use of a set of apparatus that is heavy or bulky is assumed to be introduced directly as an object into the device according to the invention, then the deflected sunbeams can be oriented away from the object of the device according to the invention to this set of devices, without even a movement of the set of devices being necessary.

Advantageously, the object, according to another embodiment of the present invention, has at least one reflection element, which concentrates and / or deflects the sun's rays that come from the reflectors to a useful element. For example, in a complementary way, or instead of a concentration of the light rays by means of the reflectors, an increase of the intensity of this type can be achieved by means of the concentration, also, with a suitable reflection element of the object . The useful element can also be arranged separately from the object.

According to another preferred embodiment of the present invention, the object is coupled with a thermal machine, in particular a hot gas turbine or a steam turbine, which means of the thermal machine can be heated by means of the sun's rays deviated For example, with the help of deflected sunbeams, water can be evaporated to form water vapor, with which a steam turbine can be operated to generate electric current. It is also possible to heat, with the deflection of the sun's rays towards the object, air or other gas, with which a turbine can be operated properly.

According to an embodiment of the present invention, the object is coupled with heat accumulator, in which the heat accumulator means can be heated by means of the deflected sun rays. In this case, for example, it may be planned to heat, for example, paraffin with the aid of the sunrays diverted at a temperature of 100 ° C to 150 ° C, the thermal energy stored in the paraffin being subsequently removed from the paraffin.

In another advantageous embodiment, the device according to the invention also has the following characteristics. A first reflector of the various reflectors is provided for the deflection of the sun's rays with a first plane angle from a plane of the sun's path, and is coupled with a first axis. The first axis, in this case, is inclined and / or can be tilted with respect to an orientation plane of the axis arrangement at a first angle between axes, being inclined and / or being able to tilt the first reflector with respect to the first axis in a First angle of the reflector. The first angle between axes, in this case, is in the opposite direction to the first angle of the reflector and the first angle of the plane. In other words, in a side view there is, for example, a deflection of the reflection of a sunbeam that strikes horizontally counterclockwise with a first axis tilt relative to a vertical orientation plane clockwise, and a corresponding tilt of the first reflector against the first axis counterclockwise (see also, for example, Fig. 17).

The orientation plane of the arrangement of axes is a plane determined by means of the arrangement of axes, preferably also geometric, which during operation is oriented in a predetermined way towards the path plane of the sun. In the device as shown, for example, in Figures 4a-4c, 5, 6 or 16, the orientation plane results as the plane defined by means of the device axes. In case the axis arrangement is formed as a flat support structure, then the orientation plane of this axis arrangement preferably results as the plane defined by means of the support structure.

A flat mirror that is oriented perpendicularly to the plane of the supposed path of the sun, reflects in parallel to this plane of the sun's path the sun's rays that hit it in the same plane. A correspondingly oriented parabolic mirror for the concentration of the sun's rays concentrates the sun's rays that hit it at a point (region), which is also in the sun's path. With the mirrors oriented in this way, only the objects that meet the mirrors together in a plane parallel to the sun's path can be irradiated in the first place.

In an embodiment corresponding to claims 4 or 5, a part of the reflectors are inclined or can be inclined with respect to the corresponding axis, the axes being preferably oriented perpendicularly with respect to the sun's path plane. With the inclined or tiltable reflectors in this way, the sun's rays can be deflected out of the plane of the apparent sun's path, which makes it possible to coordinate several reflectors arranged one above the other so that the sun's rays deflected through them strike in an object, which is not with the reflectors in a plane parallel to the sun's path plane. In this case, however, with a greater angle of the plane, that is, with a large deflection of the sun's rays from the plane of the sun's path, it may be difficult to focus on the sun's rays reflected on the object. A solution for this according to the invention, as described, for example, above, resides in a corresponding compensation by means of adapting the tilting angle or inclination of the reflectors.

It has now been found that, surprisingly, also in the case of greater plane angles, a good and simple approach can be achieved by the inclination described above of the first axis, which is assigned to the first reflector, with respect to the plane of orientation of the arrangement of the axis, for example a plane perpendicular to the plane of the sun's path, in particular a plane perpendicular to the direction of incidence of the sun's rays, and the inclination of the reflector with respect to the first axis.

The at least one other reflector of the device according to the invention of this embodiment, on the other hand, can be arranged as the first reflector, that is, also coupled with an inclined axis with respect to the arrangement of axes, and inclined with respect to it. , or it can also be connected with a parallel axis with respect to the orientation plane of the axis arrangement. The other reflector or the other reflectors, or the elements connected with them of the device can also be configured, in particular, in the manner that can be extracted from claims 4 to 8.

In another preferred embodiment of the present invention, the device has a second reflector as one of the reflectors that is intended for deflection of the sun's rays at a second angle of the plane, which differs from the first angle of the plane, removing them from the plane of the sun's path, and is coupled with a second axis, the second axis being inclined or being able to be tilted in front of the orientation plane of the axis arrangement at a second angle between axes, being inclined and / or being able to tilt the second reflector with respect to to the second axis at a second angle of the reflector, and the second angle between axes being in the opposite direction to the second angle of the reflector and the second angle of the plane. With this, with the first reflector a deviation can be achieved at a first angle of the plane, and with the second reflector a deviation can be achieved at a second angle of the plane, whereby, for example, two or several corresponding "stages" of reflectors orient the incident sunbeams to the same object as a result of the angles of adapted planes.

According to another embodiment of the present invention, the angle of the reflector corresponds to the angle of the plane, and the angle between axes corresponds to a half in the opposite direction of the angle of the plane. In general, the value of the angle of the plane with an incidence of sun rays perpendicular to the orientation plane of the axis arrangement is equal to twice the difference between the values of the angle between axes and the angle of the reflector, since with the inclination of the reflector and the axis with the non-tilted reflector results in an angle between the reflector and the orientation plane that is equal to this difference. It has been found that with the arrangement indicated above, especially good results can be achieved.

In a preferred embodiment, the arrangement of axes is configured so that the orientation plane can be oriented by means of an inclination perpendicular to a path plane of the sun. With an orientation plane oriented perpendicular to the sun's path, a particularly simple guidance of the sun's rays on the object can be achieved.

In another embodiment of the present invention, the arrangement of axes has a large number of axes, and is configured such that the axes can be tilted transversely with respect to the orientation plane. If the arrangement of the axes is oriented during operation in such a way that the axes are arranged next to each other essentially in the east-west direction, the reflectors being opposed to the sun, then the axes can be adapted by means of a inclination transversely to the plane of orientation to the variation of the plane of trajectory of the apparent sun throughout the year.

In another embodiment of the present invention, the arrangement of axes has a large number of axes, and is configured such that the axes can be tilted parallel to the orientation plane. An axis arrangement oriented as described above along the east-west direction has a comparatively small effective surface in the morning or in the afternoon. When, now, the effective surface in front of the sun has to be increased in the afternoon or in the morning, or when an orientation in the east-west direction is not possible, then, with an arrangement of axes, which allows an inclination of the axes parallel to the orientation plane, an orientation of the axes arrangement can also be performed in the extreme case along a north-south direction, being able to adapt the inclination of the axes to the meridian height of the sun or to the inclination of the plane of the apparent sun's path.

Advantageously, the arrangement of axes can be configured in such a way that it allows an inclination of the axes both transversely and parallel to the orientation plane.

The embodiments described in the preceding paragraphs with the features according to claim 21 can be advantageously combined with other features disclosed in this application, in particular with the features defined in claims 6, 7 and 13 to 20, and that are in relation to them.

In the accompanying drawings, as well as in the explanations relating to these drawings, the corresponding elements between them are designated with corresponding reference symbols.

Fig. 1a shows a mirror 10 that is arranged so that it can be tilted around an axis 20, to deflect the sun's rays 40 that depart from the sun 30 to a hot-spot 50 as an object. Deviated sunbeams are designated with 40 ’.

Fig. 1b shows a situation corresponding to Fig. 1a, in which the sun 30 has taken another position referring to the arrangement formed by mirror 10, axis 20 and object 50.

In Figures 1a and 1b, the plane of the drawing coincides with the path of the sun (apparent), the axis 20, around which the mirror 10 is arranged so that it can be tilted, arranged perpendicularly with respect to the plane of the He drew.

The mirror 10 that can rotate or that can be tilted around the axis 20 can be oriented during the course of the day in such a way that it sheds the sunlight 40 that strikes it at all times on the fixed hot surface 50 in relation to to axis 20.

The two figures 1a and 1b illustrate positions of the sun at different times of the day, and the corresponding position of the mirror with respect to them.

Fig. 2a shows a first example of a device 100 with an axis 20 and reflectors 10, 12, which are arranged so that they can be tilted around axis 20. Mirrors 12 are inclined with respect to axis 20, so that the rays of sun 40 that fall are deflected from the mirrors 10, 12 to the hot surface 50 as rays 40 'deflected.

Fig. 2b shows an arrangement that is similar to that of Fig. 2a, in which, however, all mirrors 12 are inclined with respect to axis 20, so that the hot surface 50 is arranged as an object outside the Lightning trajectories 40 incidents.

In Figs. 2a and 2b, the sun's trajectory plane is perpendicular to the plane of the drawing, and is parallel to the rays 40 that strike. Correspondingly, axis 20, as in Fig. 1, is perpendicular to the sun's path plane. Fundamentally, Fig. 2a and 2b differ only by means of the arrangement of the hot surface 50 in relation to the mirrors, and by means of the mirrors 12 correspondingly inclined in another way with respect to axis 20. The arrangement of the Fig. 2a conditions that, while the sun (not shown in Fig. 2a), the hot surface 50 and the mirror 10 are on a line, the hot surface 50 throws one on the device 100. A shadow cast from it type does not occur in the arrangement as shown in Fig. 2b.

Fig. 3 shows a second device 100, in which three mirrors 10 are arranged next to each other, which can be tilted around corresponding axes 20, the mirrors 10 being again arranged such that the sun's rays 40 which affect the hot surface 50 are deflected. As in Figures 1a and 1b, in Fig. 3 the plane of the sun's path coincides with the plane of the drawing.

Fig. 4a shows another aspect of an example. Similar to the arrangement shown in Fig. 3, there are three parallel axes 20, correspondingly arranged mirrors 10 that can be tilted around these axes. In addition there is a tilting drive system 60 for joint tilting of the mirrors 10 around the corresponding axis 20. The tilt drive system has a rod 62, which is connected respectively through a lever 64 with the combination formed by mirror 10 and axis 20, so that a displacement of the rod 62 above the lever 64 causes a tilt corresponding of the mirror 10 around the axes 20. The axes 20 with the corresponding mirrors 10, thereby, are connected by means of the rod 62 and the lever 64 such that a single motor is sufficient to keep all the mirrors 10 oriented. throughout the day in an appropriate way towards the sun (not shown), so that the reflected light always illuminates the hot surface (not shown in Fig. 4a). In the arrangement of Fig. 4a, the three axes 20 respectively rotate around the same angle. When the levers 64 have different lengths, as shown in Fig. 4b, then the turns are made around the corresponding angles. A rotation, for example, of the central mirror at an angle f <2, due to this, is accompanied by a rotation of the upper mirror at an angle f <3, that is, the rotation angle f <3 is not the same as the angle of rotation f <2, but is a function of the angle of rotation f <2, which can be achieved with a proper suspension of the mirrors. The corresponding suspensions are fundamentally known to specialists, and therefore it is necessary to describe in detail the large number of possible suspensions.

Similarly, it is possible to swing several mirrors assigned to a common axis (see, for example, mirrors 10, 12 in Fig. 2a or in Fig. 2b) independently of each other around a different angle between them, every time that it is not necessary that all mirrors assigned to a common axis be tilted at an identical angle. An additional shaft 21 is provided in Fig. 4c, which is connected through a lever 65 with a mirror arrangement similar to Fig. 4a. As a consequence of the different length of the lever 64, 65, the rotation of the axis 21 around at an angle <a results in a tilting of the mirror 10 at an angle <b, which differs from the angle <a. If different arrangements are provided, as shown in Fig. 4c, as "steps", for example, one over the other, so that for each of the axes 20 of Fig. 4c an arrangement results similar to those of Fig. 2a or Fig. 2b, then the mirrors of a “stage” can be controlled in a common way through axis 21. If, in this case, for different “stages” are provided levers 65 of different lengths, then several mirrors are used, even if they are assigned to an axis (see Fig. 2a).

Fig. 5 shows an arrangement of axes 70 with three axes 20 arranged in parallel, to which a mirror 10 is correspondingly assigned, which is arranged so that it can be tilted around the corresponding axis 20. The arrangement of the axes 70 also has a frame 72 in which the axes 20 are arranged. The representation in Fig. 5 corresponds to a view in the longitudinal direction.

Fig. 6 shows the arrangement of the axis 70 with the axes 20, the corresponding mirrors 10 and the frame 72 from Fig. 5, in a view of a plane parallel to the axes 20. The arrangement of axes 70 has three axes 20, to which three mirrors 10 are assigned, so that the arrangement of axes 70 is provided with a total of 9 mirrors.

In the arrangement of shafts 70 which is represented in Fig. 6, the shafts 20 are arranged at right angles to the bottom of the frame 72. A device with such an arrangement of shafts 70 could be deposited, for reasons of simplicity, and thereby cost savings, in a simple manner, on a flat base, so that the lower part of the frame 72 was horizontal, as indicated in Fig. 6.

Fig. 7a and 7b correspondingly show a device 100 with an arrangement of axes 70 with an object 50 coupled thereon in a different orientation. In Figures 7a and 7b, the coupling between the object 50 and the arrangement of shafts 70 is formed by a simple mechanical connection. In the representation of Fig. 7a, the plane of the sun's path (apparent) is arranged perpendicularly with respect to the plane of the drawing, as indicated by the sunbeam 40, which has a right angle on the arrangement of axes 70. Fig. 7b shows an inclined axis arrangement with respect to the representation in Fig. 7a, with a corresponding object 50 moved, so that the arrangement of axes 70 and object 50 are adjusted on the trajectory plane of the sun.

Fig. 8 shows an example with an axis 20 and mirrors 10, 12 that can be tilted around this axis, in which the axis 20 is inclined as a constituent part of an arrangement of axes relative to the horizontal floor 80 in such a way that a vector that is perpendicular to the axis 20 (indicated by means of the arrow in Fig. 8) is oriented towards the sun 30. The mirrors 12 are inclined similarly to Fig. 2a and 2b with respect to the axis 20, so that the sun's rays (not shown here) reflected by the mirrors 10, 12 converge in a region between the sun 30 and the axis 20, and affect an object (not shown).

In an arrangement of axes, as represented in Fig. 6, the arrow represented in Fig. 8 corresponds to a normal vector with respect to a plane that is defined by means of frame 72 or by means of axes 20. In the normal hemisphere, with this, this normal vector, with an east-west orientation of arrangement 70, would be oriented to the south.

In the examples explained above, the reflectors are formed by means of flat mirrors 10. Alternatively, or in a complementary way to flat mirrors, concave or reflector mirrors can also be used, which make a greater concentration of solar radiation possible, and also allow a parallel ray of light to be generated from reflected sun rays 40 '. , causing the concentrated light 40 'reflected by the concave mirrors 10 to be reflected in another convex or concave mirror 50, as depicted in Figures 9 and 10.

An arrangement with 3 concave mirrors 10 is shown in Fig. 9, which are arranged so that they can be tilted around corresponding axes 20. The mirrors 10 are oriented in such a way that the incident sun rays (not shown in Fig. 9) are deflected and concentrated on the object 50. The object 50 is formed by a concave mirror, which reflects the sun's rays 40 'reflected in such a way that they deviate to a parallel beam of light.

The representation in Fig. 10 corresponds mostly to the representation in Fig. 9, in which the object 50 is formed by a concave mirror, which also parallelly guides the sun rays 40 'deflected by the mirrors 10.

In Fig. 11, 2 of the arrangements shown in Fig. 9 are combined, in which the objects 50 are oriented in such a way that the sun rays 40 'deviated by them impact on a common object 50'.

The different reflectors or mirrors are represented in Figures 9 to 11 with radii of fundamentally coinciding curvatures. In a conversion, however, different radii of curvature may also be provided for different mirrors.

In Fig. 12a, a mirror 10 is represented with a normal vector 15 perpendicular on the surface of the mirror, and sunlight 40, 40 ′ incident and reflected. In the representation of Fig. 12a, the plane of the sun's trajectory is in the plane of the drawing. The projection of the angle between the normal vector 15 and the sunbeam 40 incident on the plane of rotation of the sun is designated with a. The projection of the angle between the normal vector 15 and the sunbeam 40 'reflected on the plane of rotation of the sun is designated with a'.

As long as the normal vector 15 is parallel to the plane of rotation of the sun, that is, that the mirror 10 is oriented perpendicularly to the plane of rotation (apparent) or plane of the sun's path, then a and a 'are identical, and the reflected 40 'ray is in the plane of the sun's orbit.

An inclination of the mirror 10 is shown in Fig. 12b with respect to the sun's path plane, which results from the incident sunbeam 40. In the representation of Fig. 12b, the plane of the drawing is perpendicular to the plane of the sun's orbit. The inclination of the mirror corresponds to the angle between the normal vector 15 on the surface of the mirror 10 and the incident sunbeam, and is designated in Fig. 12b with 1. When the projection of the normal vector 15 on the sun's trajectory plane and the incident light beam 40 are parallel, then the angle l between the normal vector 15 and the incident light ray 40 corresponds to the angle l 'between the vector normal and the light beam 40 'reflected.

In the event that the special cases described above do not occur, there will usually be no longer an identity between a and a ’or between l and l’, depending on the differences between a and a ’and between l and l’, respectively of a and l. For example, for a = 30º and l = 15º, they differ from y to ’, as well as l and l’ approximately by 4º.

In the event that a device now has a large number of mirrors that, as shown in Fig. 6, are arranged both side by side and one above the other, an inclination of the mirrors to the axis is required 20 corresponding, for, as represented in Figures 2a and 2b, to achieve an object 50 common with the sun rays 40 'reflected.

A mirror 12 inclined in this way is represented in Fig. 13, in which the angle between the inclined mirror 12 and the assigned axis 20 is designated with <. The sunbeam that strikes from the sun 30, as a result of the inclination of the mirror 12 is deflected out of the plane of the sun's path, and is designated with 40 ’.

If, in the orientation of an axis arrangement or of the reflectors assigned to the axis arrangement, the dependence of the reflection direction of the angles a and l is not considered, then, depending on the geometry of the device, it may happen that no all the sunrays deflected by the reflectors affect a common region. This, in the example of flat mirrors, can lead to the fact that, although the surface radiated by an individual mirror is not larger than the surface of the mirror, the surface illuminated by the mirror arrangement, however, is larger than the individual surface of the mirror. mirror, that is, the individual surfaces only partially overlap.

In one form, the object 50 has a useful element 50 ’, in which by means of a reflection element 90 the sun rays deflected by the reflectors or from the mirrors of the device can be concentrated or deflected.

In Fig. 14a, next to the useful element 50 'two mirrors 90 are arranged, which reflect the sunlight 40' deflected by the reflectors, which is not directly oriented to the useful element 50 ', so that the sun's rays 40' 'deflected again affect the useful element. In Fig. 14b, another embodiment is shown, in which there is a focusing mirror 90 that deflects the sun rays 40 'deflected passing by the useful element 50', so that the sun rays 40 '' deflected again they affect the useful element 50 '.

In addition, it can be provided that the rotation element is arranged in a mobile way, and that it can modify its position throughout the day, so that an optimized diversion to the useful element is possible.

Alternatively, or in a manner complementary to that described, it may be envisaged to consider the dependence of the reflection direction on the orientation of the reflectors on the orientation of the reflectors, so that a corresponding compensation is made. This can be done, for example, by means of a corresponding transmission device, as represented, for example, in Fig. 4b. In the same way a compensation of a plane perpendicular to the plane of the sun's orbit can be carried out. With a suitable transmission device the orientation of the reflectors can be arranged according to the height of the sun throughout the day for individual mirrors such that the surfaces illuminated by the individual mirrors overlap each other greatly or even completely, it is that is, a better "approach" or a complete "focus" is made. If necessary, a permanent approach to the system can be achieved through simple mechanical compensation mechanisms.

The movement of the individual mirrors can be coupled in this case, although as a consequence of the transmission device, the individual mirrors, however, perform different movements.

An example is shown in Fig. 15, in which the axis arrangement of the axes 20 is oriented with corresponding mirrors 10 in the east-west direction, such that a normal vector with respect to a plane that is determined by means of Axis 20 points south. As indicated in Fig. 15, the sun 30 is in the morning and in the afternoon at a great angle to the normal vector of the arrangement, so that the device presents 40 incidents in a sun such case only a comparatively reduced effective surface.

In Fig. 16, axle arrangements are illustrated, which are also indicated to offer as large an effective surface as possible in the morning or in the afternoon so that more solar energy can be used. In this case, the axes 20 are no longer perpendicular on the lower part of the frame 72, the axes 20 and the frame 72 being shaped such that the angle enclosed between them can be adapted by means of an inclination along the frame 72 at the meridian height of the sun that changes over the years.

Fig. 17 shows a representation of an aspect of a device according to the invention. The flat mirror 210 is coupled so that it can be tilted with the shaft 220, which in turn is connected to an axle arrangement (not shown). The mirror 210 is inclined in front of the axis 220 at an angle of the reflector 218, that is, in the representation of Fig. 17 counterclockwise. The axis 220, on the other hand, is inclined with respect to an orientation plane 212 of the axle arrangement (not shown) at an angle between axes 216, resulting in the direction of inclination of the axis 220 with respect to the orientation plane 212 opposite the direction of inclination of the mirror 210 with respect to the axis 220, that is, in the representation of Fig. 17, the axis 220 is inclined with respect to the orientation plane 212 in a clockwise direction. The mirror 210 is in the representation of Fig. 17, thereby, at an angle of inclination with respect to the orientation plane 212 that results from the difference in the values of the angle of the reflector 218 and the angle between axes 216. In Fig. 17, in addition, a sunbeam 40 is shown which is perpendicular to the orientation plane 212, which is reflected by means of the mirror 210, enclosing the sunbeam 40 'reflected a flat angle 214 with the beam of incident sun 40, whose value is twice as large as the angle of inclination with which the mirror 210 is inclined with respect to the orientation plane 212, since the orientation plane 212 is oriented perpendicularly to the path plane of the sun. The sun's trajectory plane is perpendicular to the paper plane of the representation in Fig. 17. Also in a tilting of the mirror 210 about the axis 220 over a day, to adapt the position of the mirror to the path (apparent ) of the sun, with the arrangement according to the invention, an orientation of the ray 40 'reflected on the object (not shown) can be maintained for the most part. The reflected sun rays 40 'are no longer in the sun's path plane, so that the object, which, likewise, is no longer in the sun's path plane for the mirror 210, does not cast shadows on the mirror 210, as could happen when the mirror and the object meet the sun in a common plane.

Fig. 18 shows an embodiment of the device 200 according to the invention with three axes 220 and three mirrors 210, which are arranged so that they can be tilted around a corresponding axis 220. The mirrors 210 are inclined with respect to the corresponding axis 220, and are arranged or tilted in such a way that the incident sun rays 40 are deflected by the mirrors 210 to the hot surface 50 as deflected rays 40 '. The angle of inclination or of the reflector of the mirrors 210 with respect to the axes 220 is indicated by the sketched perspective representation (dotted line). With respect to the orientation plane (not shown in Fig. 18), the axes 220, on their side, are inclined at an angle between axes in the direction of incidence of the sun's rays 40, this inclination also being indicated by means of a corresponding perspective representation (dotted line). The mirror 210, therefore, is also inclined in front of the orientation plane of the axis arrangement (not shown), whereby the sun's rays 40, which affect a plane of solar path (supposed), which coincides with the drawing plane, they deviate out of the sun's path plane. With this, goal 50 is also not in the drawing plane of Fig. 18.

Fig. 20 shows another aspect of an exemplary embodiment of the present invention. Similar to the arrangement shown in Fig. 18 there are three parallel axes 220, mirrors 210 being arranged respectively so that they can be tilted around these axes 220. In addition there is a tilting drive system 60 for common tilting of the mirrors 210 around the corresponding axis 220. The tilting drive system has a rod 62, which is connected respectively by means of levers 64 with the combination formed by the mirror 210 and the shaft 220, so that a displacement of the rod 62 through the lever 64 causes a corresponding tilting of the mirrors 210 around the axes 220. The axes 220 with the corresponding mirrors 210 are thereby connected through the rod 62 and the lever 64 such that a single motor is sufficient to keep all the orientations oriented. mirrors 210 in the course of the day suitably towards the sun (not shown), so that the reflected light always illuminates the hot surface (not shown in Fig. 20). In the arrangement of Fig. 20, the three axes 220 respectively make turns with the same angle.

When the levers 64 have different lengths, then the turns are made at correspondingly different angles, which can be carried out by means of a suitable suspension of the mirrors. The corresponding suspensions are known primarily to specialists, and therefore it is necessary to describe in detail the large number of possible suspensions.

An additional shaft can also be provided which is connected through another lever with a mirror arrangement similar to Fig. 20. As a consequence, for example, of a different length of the levers results, upon rotation of the shaft with a angle <to a tilting of the mirrors, respectively, with an angle <b, which differs from the angle <a. If several such arrangements are arranged as "stages", for example, one over another, then the mirrors of a "stage" can be controlled together through the axis.

Naturally, alternatively, or in a complementary manner to the lever systems described herein, other structures, for example sprockets and / or belts, can also be used.

Fig. 22 shows an arrangement of axes 270 according to an aspect of the invention with three axes 220 arranged in parallel, to each of which a mirror 210 is assigned, which is arranged so that it can be tilted around axis 220 correspondent. The arrangement of the shaft 270 also has a frame 272, in which the shafts 220 are arranged. The representation in Fig. 22 corresponds to a view parallel to the direction of orientation of the arrangement of shafts 270. The support structure carried by means of the frame 272, it also determines in the exemplary embodiment shown in Fig. 22 the orientation plane (not shown) of the axis arrangement 270, the orientation plane being in this case in the representation of Fig. 22 perpendicular to the plane of the drawing and parallel to the longitudinal direction (from top to bottom) of the representation of the frame 272. Other arrangements are naturally equally possible, there being, in particular, no limitation as regards symmetrical embodiments.

The embodiments or aspects shown in Figs. 19, 21 and 23 differ from those shown in Figs. 18, 20 and 22 only in that the axes 220 are inclined in the corresponding axis inclination planes with respect to the orientation plane (in this case perpendicular to the incident sunbeams), which are not parallel to the axes 220 represented by a plane. The axes 220 are inclined here, respectively, in their own axis inclination plane, in which case a axis inclination plane is defined respectively by means of a non-inclined (hypothetical) axis (as in Figures 19, 21 and 23 would be perpendicular to the representation plane) and the axis 220 inclined. In other words, it can be said that the corresponding axes 220 are inclined at an angle between axes relative to the orientation plane (not shown here), which (along axis 220) in addition to the polar component (i.e., an angle of inclination in the axis inclination plane) it has an azimuthal component (that is, an orientation in the representation plane of Fig. 19, 21 and 23 corresponding to a rotation of the axis inclination plane). In the representations in Figs. 18, 20 and 22, the azimuthal component is zero. In the representations of Figs. 19, 21 and 23, the axes 220 are oriented respectively in azimuth towards the focus or towards the object 50. Other orientations are also possible, for example with a comparatively greater or lesser azimuth component.

Figs. 24a and 24b show respectively a device 200 according to the invention with axes arrangement 270 with an object 50 coupled thereto in a different orientation. In Figures 24a and 24b, the coupling between the object 50 and the arrangement of axes 270 consists of a simple mechanical connection. In the representation of Fig. 24a, the plane of the sun's path (apparent) is arranged perpendicular to the plane of the drawing, as indicated by means of the sunbeam 40, which has a right angle on the orientation plane of the axes arrangement 270. Fig. 24b shows an inclined axis arrangement with respect to the representation in Fig. 24a, with a corresponding moving object 50, so that the axes arrangement 270 and the object 50 are adjusted to the plane of modified sun trajectory.

Fig. 25 shows an exemplary embodiment of the present invention. The device 200 comprises a device with mirrors 10 and axes 20, similar to Fig. 8, the axes 20 being oriented perpendicularly to a direction of incidence of the sun's rays from the sun 30. In Fig. 25 it is shown in section transversal, however, only one axis 20 with a corresponding mirror 10. The axis 20 is inclined as a constituent part of an arrangement of axes with respect to the horizontal floor 80 such that a vector arranged perpendicularly in front of the axis 20 (indicated by means of the arrow in Fig. 25) is oriented towards the sun 30. The device 200 shown in Fig. 25 further comprises mirrors 210, which are inclined with respect to a corresponding axis 220, the corresponding axis 220 being inclined, on its side, with respect to the orientation plane 212 given by means of the arrangement of axes. By means of the resulting inclination of the mirrors 210 with respect to the orientation plane 212 (and thus, also with respect to the mirror 10) it is achieved that the sun's rays reflected by the mirrors 10, 210 converge and strike an object (not shown) ).

By way of example, flat mirrors are provided in the embodiments described in relation to Figures 17 to 25. However, according to the invention, other forms of mirrors and types of reflectors are also possible, for example correspondingly to the embodiments shown in Figures 9 to 11. The same is true for embodiments relating to the configuration of the object, in particular as regards Figures 9 to 11, 14a and 14b.

In the accompanying drawings, for simplified representation, the axes are arranged, respectively, centrally with respect to the corresponding reflectors. According to the invention, however, another arrangement may also be provided, as long as a tilting of the reflectors around the corresponding axis is possible.

With the present invention a device and a method for the use of solar energy are presented, which allow a cheap construction compared to the known procedures and devices.

In an advantageous embodiment, the invention provides a device and method for the use of solar energy, in which neither a large individual mirror has to be moved as a whole, nor a large number of small mirrors have to be rotated, each one for himself, around another axis or around two axes, but several mirrors or reflectors have to be turned in, for example, parallel axes between them (see, for example, Fig. 3 or 6), thanks to which a cheaper construction is possible in comparison with the known procedures and devices: a square meter of flat mirror costs approximately € 30. The frame, in which the axes are fastened, costs approximately € 50 per square meter. To this we must add the shaft, some small parts, a stepper motor with microprocessor in sum of approximately € 100 to € 150, for material costs. To this we must add approximately € 50 for assembly. In the event that a square meter of mirror surface accumulates approximately 500 kilowatt hours in the year, then this results in 10 years

5,000 kilowatt hours, resulting in a price of approximately € 0.04 per kilowatt hour, which corresponds approximately to the price of energy from oil or gas.

In an exemplary embodiment of the present invention, the axis of rotation or tilt of each mirror is not identical with an axis perpendicular to the sun's path, nor is it parallel to this axis. The mirror is connected, however, through the axis with the arrangement defining a plane, which is preferably perpendicular to the direction of incidence of the sun's rays. The axis of rotation or tilt of the mirror tilts at an angle c, and the mirror is mounted on this axis in such a way that it forms a 2-c angle with it. In this way, the mirror surface points more clearly downwards or upwards when the mirror is turned or tilted. The mirror, when turning (tilting), is lowered (or raised) slightly, and thereby deflects the light more strongly downwards (or upwards).

Two axes are now moved, each of them by means of an engine: an engine maintains the arrangement with the axes, on which the mirrors are mounted, throughout the year perpendicular to the sun's path, not being oriented in this at least some of the axes themselves perpendicularly with respect to the sun's path, since they are inclined with respect to the orientation plane of the axis arrangement. A second motor rotates the mirrors during the day around these axes.

With a simple inclination of the mirrors with respect to an axis that is perpendicular to the plane of the sun's path (apparent), the problem arises that the light reflected by them, usually, both in the plane of the sun and perpendicularly with respect to The latter is not at the same angle as the incident light, which makes it difficult to focus through a common orientation of the mirrors on an object.

When, for example, the mirror has to be tilted by 5º, so that the light deflects down by 10º, in one embodiment the axis of rotation of the mirror tilts 5º upwards (with respect to an assembly plane), adjusting at the same time the angle between this axis and the mirror at 10º, so that, again, the mirror shows the required 5º (with respect to the assembly plane) downwards. In one embodiment, a mirror can be correspondingly inclined on a wing of a conventional hinge, the other wing of the hinge being fixed in a mounting frame, so that the hinge axis is inclined with respect to the mounting frame.

In comparison with conventional systems in parabolic mirror systems (with three-dimensional mirror curvature), parabolic groove systems (with two-dimensional mirror curvature) and sun towers, according to the invention, simplifications are given by the fact that they can be used cheaper flat mirrors, you should not move a large and heavy mirror system (as in the case of a parabolic mirror), but only a certain number of axes that each carry only the weight of the mirror assigned to them, while a large part of the support structure (frame) does not move during the course of the day, and in addition it is not necessary to adjust a large number of mirrors on two axes each, as provided in the case of the solar tower
