Description

  The present invention relates to a water channel power generator, and more particularly to a small water channel power generator suitable for installation and use in an agricultural water channel.

  For example, a water channel power generation apparatus that is installed in an agricultural water channel or the like and generates power using the flow of the water is well known (see Patent Document 1 and Patent Document 2). Here, the water channel power generation device described in Patent Document 1 is configured to generate power with a generator by rotating a water wheel using a water flow flowing through the water channel by immersing the lower part of the water wheel in the water channel. Further, the water channel power generation device described in Patent Document 2 is configured to provide a head portion in the middle of an agricultural water channel, and to generate power with a generator using a water flow accompanying the water head in this portion.

  However, both the prior arts disclosed in Patent Document 1 and Patent Document 2 have a large configuration of the entire power generation device, and when selecting a location such as a water channel to be installed, a location having a sufficient flow can be specified or In addition, additional work such as installing a weir in the irrigation channel itself is required, and there are considerable restrictions on the installation location, and the work for installation becomes large, which requires a considerable period of time for installation work. I was trying. Also, once installed, it was costly to re-install in another location. There is also a problem that the power generator cannot be used during the period of re-installation. Therefore, it was difficult as a practical problem to re-install the power generation device in a more preferable place. Furthermore, since the conventional power generator has a large structure, it requires regular maintenance even after it has been installed.

  In addition, when the power generator is installed in, for example, an irrigation channel, a considerable portion of the entire power generation device protrudes upward from the irrigation channel.For example, when the power generator is installed in an agricultural channel with a peaceful atmosphere naturally overflowing, There was a case where the scenery of was damaged. In particular, if the entire power generation device is made of metal in consideration of the durability of the device, rust has become conspicuous in the power generation device itself due to long-term use, and this problem has become more serious. On the other hand, when the protruding portion of the power generation device is made of wood, there is a problem that durability cannot be sufficiently maintained and the power generation device itself cannot be used for a long time. In addition, for example, trying to install a power generation device in a irrigation channel or a stream in a developing country where infrastructure is not established, there is a cost of transporting each part, and it is necessary to dispatch engineers necessary for the installation. In addition, a special engineer must not perform the maintenance, and the installation of the power generation device in such a place is actually difficult.

  In addition to the above, the conventional technology has a problem in that the rotational force (rotational moment) exerted on the water wheel used for power generation varies depending on the change in the water level of the water channel or river. In other words, the water level of a waterway or river always changes depending on the season, weather, etc., but when generating electricity using the flow of water in a waterway or river, the position of the blades and the water level of the water wheel used for power generation is always the predetermined position. This relationship is necessary to obtain stable power generation efficiency. However, it is impossible to maintain such a predetermined positional relationship with a structure such as the prior art in which a water turbine or the like is installed in a state where it is set at a certain height. In particular, when the water level of a waterway or river is low, there is a problem that power generation efficiency is extremely lowered because sufficient rotational force is not transmitted to blades of a water wheel or the like.

  In addition, in the structure of the prior art in which a water turbine or the like is installed at a certain height as described above, a solid support is provided to securely install the power generator equipped with this water turbine around a waterway or a river. If the size of the support part (width dimension across waterways and rivers) is constant, it can be installed only in waterways and rivers with a width that matches this. There was also a problem that it was impossible to do so and the installation location was limited. On the other hand, in order to make a general-purpose power generator that can cope with various waterway widths and river widths, the support section must be provided with a straddle width adjusting mechanism corresponding to this, which further increases the cost of the apparatus itself. It was.

  An object of the present invention is to provide a water channel power generation device that can be easily installed and removed from any location of various water channels such as agricultural water channels, city water channels, and campsite creeks, and does not impair the scenery around the water channel. There is.

In order to solve the above-described problem, a water channel power generator according to claim 1 is:
A base portion having sufficient buoyancy to float on the water surface of a water channel in which water flows in a predetermined direction;
A shaft rotation drive unit provided on the water contact surface of the base unit;

The rotation driving unit includes a circular rotating body that can rotate relative to the base unit with a direction orthogonal to the water surface of the water channel as a rotation center, and a blade unit provided at least in one radial direction of the circular rotating body. And when the blade portion moves from the upstream side to the downstream side of the water flow in the water channel with the rotation of the circular rotating body, the blade portion is displaced to a position orthogonal to the direction of the water flow, and the blade portion When moving from the downstream side to the upstream side of the water flow in the water channel, the blade part moves to the downstream side of the water flow because the entire blade part is displaced to a position parallel to the water flow. The circular rotating body is rotated in a certain direction by utilizing the resistance received from the flow of water at the time, and this rotational force is provided in the power generation unit via the rotating shaft to transmit the generated electricity to the outside of the water channel. It is a feature.

  According to the present invention, it is possible to provide a water channel power generation device that can be easily installed and removed from any location of various water channels such as agricultural water channels, city water channels, and campsite creeks, and does not impair the scenery around the water channel. Can do.

  In the water channel power generator according to the present embodiment, the rotation drive unit includes a circular rotating body that can rotate relative to the base unit around a direction orthogonal to the water surface of the water channel, and a diameter direction of the circular rotating body. Have at least one blade portion. By having such a blade part, when the blade part moves from the upstream side to the downstream side of the water flow in the water channel as the circular rotating body rotates, the blade part is displaced to a position orthogonal to the direction of the water flow. When the blade portion moves from the downstream side to the upstream side of the water flow, the entire blade portion is displaced to a position parallel to the water flow in the water channel. Thereby, while rotating the circular rotator in a certain direction using the resistance received from the water flow when the blade part moves downstream of the water flow, the power generation unit is provided with this rotational force via the rotation shaft, The electricity generated is transmitted outside the waterway.

  Hereinafter, the above-described configuration of the water channel power generator 1 according to the present embodiment will be described in more detail. FIG. 1 is a cross-sectional view of a water channel generator according to an embodiment of the present invention cut along the diameter direction of a float. FIG. 2 is a bottom view of the water channel power generator according to one embodiment of the present invention. FIG. 3 is a perspective view showing an actual usage mode of the water channel power generator according to one embodiment of the present invention.

  The base portion is called a float 100 in the present embodiment, and has a disk shape and is composed of a foam material and a resin material that entirely covers the periphery of the foam material for waterproofing. In the case of this embodiment, the float 100 has dimensions of about 300 mm in diameter and about 25 mm to 30 mm in thickness.

  In the case of the present embodiment, the shaft rotation driving unit includes a wing support frame 200, and eight wings 251 to 258 (250) connected to the wing support frame 200 via hinges 910 and 920 (900), respectively. It is composed of In the case of the present embodiment, the wing support frame 200 is disposed about 10 mm below the float lower surface with respect to the float 100 and is a frame described later so as to be rotatable relative to the float 100 around the central axis of the float 100. It is fixed to the float 100 via the support part 220.

  The wing support frame 200 includes a ring-shaped annular frame 210, a frame support portion 220 located at the center of the annular frame 210, and a frame support portion 220 for connecting the annular frame 210 and the annular frame 210, respectively. Frame coupling portions 231 to 238 (230) that extend radially from the center of the ring frame 210 in the radial direction and couple them together.

  Two hinges 910 and 920 (900) are fixed to one side in the circumferential direction of the frame coupling portion 230 at a predetermined interval. In the case of the present embodiment, this one side means that when the water channel power generation device 1 is actually installed in the water channel and the wing support frame 200 rotates, each frame coupling portion 231 to 236 with respect to the rotation direction. It is the side located on the back.

  In the case of this embodiment, the wings 251 to 258 (250) are made of a substantially fan-shaped plate made of stainless steel (SUS). And the side edge vicinity on one straight line of each wing 250 is attached to the flame | frame coupling | bond part 230 via the hinge 900, and is rotationally displaced within the predetermined angle range (refer FIG. 5). The range in which the wing 250 is rotationally displaced (moved) via the hinge 900 will be described below.

  As described above, one of the hinges 900 (910, 920) is fixed to the frame coupling portion 230, and the other is fixed to the wing 250. The hinge 900 limits the movable range of the wing 250. Specifically, when the wing support frame 200 moves to the downstream side of the water flow, as indicated by the white left-pointing arrow in FIG. 5A, the wing 250 has a water flow (FIG. 5A). 5), the wing 250 is rotationally displaced about the movable axis of the hinge 900 from a position horizontal to the flow direction to a position orthogonal to the water flow direction f (see FIG. 5A). 2), the hinge stopper not shown in detail here stays at the position shown in (1) in FIG. 5A to receive the water flow f over the entire wing surface, and A rotational moment is applied to the rotational shaft to give further rotational force in the rotational direction of the wing support frame 200.

  On the other hand, when the wing support frame 200 moves to the upstream side of the flow of water as shown by the white arrow pointing in white in FIG. 5B, the wing 250 is not shown in detail here by the hinge stopper shown in FIG. (A) It stays at the position shown in (1), and from the position where water directly hits the wing surface (this state is not shown in FIG. 5 (b)), the direction of water flow (in FIG. 5 (b)) Rotating displacement about the movable axis of the hinge 900 to a position parallel to the thin arrow f), whereby the entire wing surface is not subjected to a force from the water flow f, and is opposite to the rotation direction of the wing support frame 200 Make sure that no rotational force is generated.

  In addition, the wing support frame 200 and the wing 250 described above are each made of, for example, stainless steel (SUS), and in the case of this embodiment, one circular plate member is replaced with six wings as shown in FIG. It is manufactured by stamping so that the remaining wing support frames are separated. A rotating shaft 240 protrudes from the center of the frame support portion 220 and is connected to a power generation shaft 440 of a generator 400, which will be described later, fixed to the upper surface of the float 100, so that the rotational force of the wing support frame 200 is reliably applied to the power generation shaft 440. To come to tell.

  In the case of this embodiment, the generator 400 is a small generator having normal specifications. That is, the generator used in the present embodiment is a generator having a generated voltage of 6 V (volts) and a generated power of about 2.4 W (watts). The generator 400 is fixed to the float 100 by a generator mounting bracket 420 made of, for example, an aluminum alloy bent in an inverted U shape when viewed from the side. From the upper part of the generator 400 fixed by the generator mounting bracket 420, a waterproof electric wire 430 having a length sufficient to reach the outside of the water channel is led out, and the end of the electric wire 430 is the end of the present embodiment. If the LED light 500 is connected.

  In the above-described embodiment, the wing 250 is a stainless steel flat plate. However, in order to increase resistance to the flow of water and increase the power generation capacity, the surface on the side where the water hits the wing is subjected to an uneven surface treatment. Or a large number of small holes may be provided in the wing so that the water does not pass through as it is, that is, it receives considerable resistance when passing through.

  Further, in the present embodiment, the hinge 900 is provided with two hinges 910 and 920 in each frame coupling portion 230 (231 to 238), but unlike this, one hinge is provided in each frame coupling portion. Alternatively, in the case of a water channel power generator having a larger size unlike the present embodiment, three or more hinges may be provided to firmly fix the hinges to the frame coupling portion.

  Further, the generator mounting bracket is made of an aluminum alloy, but it may be made of stainless steel (SUS) or a resin material having sufficient rigidity.

  In the case of this embodiment, the mooring part is composed of two mooring chains 610 and 620 (600) having a predetermined length made of resin. One end of each of the mooring chains 610 and 620 is fixed to the float, and the other end is fixed to the ground around the water channel (not shown in FIG. 3) where the water channel power generation device 400 is arranged using an anchor or the like.

  FIG. 3 shows a state where the water channel generator 1 according to the present embodiment is actually floated on the water channel. In FIG. 3, two elongated plate bodies made of aluminum alloy are used for the one set of water channel power generators 1 and 1 ′ having the respective constituent elements except the mooring chains 610 and 620 in the water channel power generator 1 described above. The floats 100 are connected to each other via connecting plates 710 and 720 (700).

  That is, in FIG. 3, one end of each of the two mooring chains 610 and 620 is connected to the float 100 of the water channel power generator 1, and each other end is anchored to, for example, the ground outside the water channel not shown in FIG. It is fixed. In addition, the float 100 of the water channel power generator 1 and the float 100 ′ of the water channel power generator 1 ′ are connected via a connection plate 710, 720 at a predetermined interval. That is, in FIG. 3, the mooring chain 600 and the connecting plate 700 cooperate to serve as a mooring portion.

  In floating the two water channel power generators 1, 1 ′ on the water surface, the water channel power generator 1 on the side connected to the mooring chain 600 is floated on the upstream side of the water flow in the water channel and connected by the connecting plate 700. The water channel generator 1 'is installed in the water channel so as to float on the downstream side of the water flow in the water channel. As a result, electric power for two units can be supplied to the outside from each water channel power generation device 1, 1 ′ via an electric wire (not shown).

  FIG. 4 is an explanatory view illustrating the operation of the water channel power generator according to one embodiment of the present invention. In FIG. 4, all the hinges 900 are shown in the same posture for simplification of description. In FIG. 4, while the wing support frame 200 rotates 90 degrees, the wing 250 located on the upstream side of the river flow is vertically downward from the position where the wing tip portion is directed diagonally downward to the right as shown in FIG. Is gradually rotated about the hinge 900 to a position facing (see an arrow indicated by a two-dot chain line in FIG. 5A). This corresponds to the position from the position of the wing 258 in FIG. 4 to the position of the wing 252 through the position of the wing 251. And while the wing support frame 200 further rotates 90 degrees, the wing 250 located in the middle of the wing support frame 200 with respect to the river flow is the position shown in FIG. From the position facing downward to the position facing diagonally downward to the right, it is gradually rotationally displaced about the hinge 900. This rotational displacement direction is the direction opposite to the direction of the arrow indicated by the two-dot chain line in FIG. 5A. This is from the position of the wing 252 to the position of the wing 254 in FIG. It corresponds to everything.

  Following this, while the wing support frame 200 rotates 90 degrees, the wing 250 located downstream of the river flow is horizontally oriented from the position where the wing tip is diagonally downward to the left as shown in FIG. Is gradually rotated about the hinge 900 to a position facing (see an arrow indicated by a two-dot chain line in FIG. 5B). This corresponds to the position from the position of the wing 254 in FIG. 4 to the position of the wing 256 through the position of the wing 255.

  While the wing support frame 200 further rotates 90 degrees, the wing 250 located in the middle of the wing support frame 200 with respect to the river flow is the position shown in FIG. The position is gradually rotated and displaced about the hinge 900 from a position facing the direction to a position facing diagonally to the left. This rotational displacement direction is the direction opposite to the direction of the arrow shown by the two-dot chain line in FIG. 5B. This is from the position of wing 256 in FIG. 4 to the position of wing 258 through the position of wing 257. It corresponds to everything.

  As described above, in FIG. 5, the wing support frame 200 is seen from the upper side in the figure by utilizing the resistance received from the water flow by rotating and displacing the wing 252 so as to be perpendicular to the river flow. A driving force (rotational torque) that rotates in the clockwise direction is generated and rotated in the counterclockwise direction so as not to receive resistance from the water flow by being rotationally displaced so as to be parallel to the flow from the wing 256. The rotation operation of the wing support frame 200 is not hindered.

  The operation of the water channel power generator according to the above-described embodiment (hereinafter referred to as “the water channel power generator according to the present invention”) will be described.

  According to the water channel power generator according to the present invention, since the configuration of the device itself is not large as the conventional water channel power generator, the water channel power generator itself can be manufactured at low cost. In addition, since the size of the device itself can be reduced, the size of the device can be easily carried, so that a suitable place for power generation can be found while carrying the water channel power generation device and installed on the spot. Can do. In addition, when the water channel power generation device according to the present invention is installed in a water channel or a stream, the device does not protrude upward from the water surface unlike conventional water channel power generation devices, so that the scenery of the surrounding landscape is not impaired. . In addition, according to the water channel power generation device according to the present invention, the installation location can be changed immediately, so when a location that seems to have higher power generation efficiency is found, the water channel power generation device once installed is installed in a more preferable location. It is easy to redo. In addition, the water channel power generation device according to the present invention is installed in, for example, an agricultural water channel, the generated electricity is charged into a battery, and the LED light is constantly turned on using the charged power, or during power generation at night The generated electric power can be used as it is, and the LED light can be turned on for use in nighttime crime prevention. In addition, the water channel power generation device according to the present invention is installed in a creek of a campsite and used as a power source for the LED light for illumination in the tent at night, or an LED light is installed on the outside of the tent so that it is always at night. It can be turned on and used for crime prevention. Further, by providing the water channel power generator according to the present invention with a function of charging a mobile phone, it may be possible to charge the mobile phone at any time even if camping is performed for a long time. This can prevent the battery of the mobile phone from running out, and is convenient because the mobile phone can always be used in any case during long camping.

  In addition, the water channel power generation apparatus according to the present invention has a very great advantage over the prior art disclosed in Patent Document 1 and Patent Document 2, which are the prior arts introduced in the column of problems to be solved by the invention. Specifically, all of the conventional technologies have a large configuration of the entire power generation device. When selecting a location such as a irrigation channel to be installed, a location having sufficient flow is specified, or a dam is provided in the irrigation channel itself in addition to the power generation device. However, the water channel power generation apparatus according to the present invention does not cause such a problem, although it requires additional construction such as the installation, is considerably restricted in the installation location, and requires a considerable period for installation. In addition, the conventional technique has a problem that once installed, it takes cost to re-install in another place, and the power generator cannot be used during the re-installation period. There is no problem. In addition, in the prior art, it is difficult as a matter of fact to re-install the power generation device in a more preferable location, and since the configuration is large, regular maintenance is required even after the installation. Such a problem does not occur in the water channel power generator according to the invention. In addition, when the conventional power generator is installed in, for example, an irrigation canal, a considerable portion of the entire power generator protrudes upward from the irrigation canal. However, the water channel generator according to the present invention does not cause such a problem. In addition, since the configuration of the water channel power generation device according to the present invention is simple, this water channel power generation device is installed in a water channel or water channel in a developing country where infrastructure is not maintained, for example, and is self-generated to generate an LED lamp or the like. It can be used as a power source or a mobile phone charger. That is, according to the water channel power generation apparatus according to the present invention, it is possible to supply necessary power without destroying the environment and maintaining a special infrastructure in any place on the earth as long as there is a irrigation channel or a stream. Become.

  Further, in the prior art, there has been a problem that the rotational force (rotational moment) exerted on the water turbine used for power generation changes due to the change in the water level of the water channel or river. In other words, the water level of a waterway or river always changes depending on the season, weather, etc., but when generating electricity using the flow of water in a waterway or river, the position of the blades and the water level of the water wheel used for power generation is always the predetermined position. This relationship is necessary to obtain stable power generation efficiency. However, it is impossible to maintain such a predetermined positional relationship with a structure such as the prior art in which a water turbine or the like is installed in a state where it is set at a certain height. In particular, when the water level of a waterway or river is low, there is a problem that power generation efficiency is extremely lowered because sufficient rotational force is not transmitted to blades of a water wheel or the like. In order to deal with such problems, it may be possible to further provide a structure for moving the water wheel up and down to an optimal position according to changes in the water level of the water channel or river in the structure of the prior art. However, it is not a structure that can be adopted practically because it requires regular maintenance.

  On the other hand, in the water channel power generation apparatus according to the present invention, the wing support frame is provided with a wing necessary for power generation because the float always floats on the surface of the water regardless of how the water level of the water channel or river changes depending on the season or weather. However, it is designed to rotate in parallel with the surface of the water just below the surface of the water. Has an excellent merit.

  In addition, in a structure in which a water turbine or the like is installed at a certain height as in the case of a conventional power generation device, the power generation device equipped with this water wheel is firmly installed in order to reliably install around a waterway or a river. It must be equipped with a support part, and the cost of the device itself is very high, and if the dimensions of the support part (the width dimension across the waterway and river) are constant, only the waterway or river having a width matching this There was a problem that it could not be installed and the installation location was limited. On the other hand, in order to make a general-purpose power generator that can cope with various waterway widths and river widths, the support section must be provided with a straddle width adjusting mechanism corresponding to this, which further increases the cost of the apparatus itself. It was.

  However, the water channel power generation device according to the present invention can be installed in waterways and rivers having various widths only by changing the length of the mooring portion using the mooring chain as an example, and thus has a different width. It is possible to easily install a common waterway power generation device for various waterways and rivers, and it is likely that optimum power generation efficiency can be obtained even if the same waterway or river is in place and the width is different. Since it is possible to find a place and install the water channel power generation apparatus according to the present invention at that place, it has an extremely superior merit from the viewpoint of generalization of the apparatus as compared with the prior art.

  In the above embodiment, the mooring chain 600 is made of metal. However, the mooring chain 600 is not limited to such a material, and a resin chain having sufficient strength may be used. You can substitute the string.

  Moreover, although it described that it was the product made from an aluminum alloy in the above-mentioned embodiment as a material of a connection plate, if it can keep the space | interval between two water channel power generation devices constant, it will not necessarily be this material, Stainless steel ( SUS) or a resin having sufficient strength.

  In FIG. 2, electricity flows directly from the generator of the water channel power generator to the LED light via the electric wire, but the electric wire led out from the generator is not necessarily configured as described above. Connect the other end to a small battery, for example, and use this battery to charge the power generated by the generator during the day and use the power supply control device equipped with a timer, illuminance sensor, etc. You may make it flow electricity to LED light only at night time.

  In addition, although the LED light was used in the above-mentioned embodiment, it is not necessarily limited to this, and any light may be used as long as it is a power saving light.

  In FIG. 3, the two hydroelectric generators are connected to the floats of the hydroelectric generators via the connection plates. However, three or more units are connected via a plurality of connection plates without necessarily taking such a configuration. These water channel power generators may be installed in the water channel via a mooring chain in a state where they are arranged in series in a predetermined interval from the upstream side to the downstream side of the water channel. In addition, for example, a large number of small water channel generators that can be used for a water channel with a water channel width of 50 cm are prepared, and the plurality of water channel power generators are orthogonal to the water channel or river flow (water channel) via the plurality of connection plates (connection members) Or in the width direction of the river). Thereby, it is possible to install in a variety of widths of waterways and rivers via the connecting members only by creating a large number of small-sized waterway power generation devices having the same dimensions.

  Furthermore, in waterways and rivers where the waterway width and river width are relatively large and have a certain width from the upstream side of the river to the downstream side, a plurality of small waterway power generators of the same size are connected via a number of connecting members. You may install in the state which floated the waterway and the river so that it might be arranged in a matrix form in the width direction of a waterway or a river, and the up-down direction of a flow. By doing in this way, it becomes possible to set it as the water channel power generator which has a considerably big power generation by superimposing the power generation of each small water channel power generator.

  As for the float, instead of the disk-like float as in the above-described embodiment, a so-called kamaboko plate-like elongated rectangular float is created, and the wing support frame, wing, and Two combinations of generators may be arranged in series.

  Note that the shape, dimensions, and material of each component in the above-described embodiment are merely examples, and various forms (shapes, dimensions, and materials) are possible as long as the effects of the present invention are exhibited. It goes without saying that is applicable.

Having a mooring portion or the like for mooring the base portion at a certain position in the water channel against the flow of water in the water channel;
The rotation driving unit includes a circular rotating body that can rotate relative to the base unit with a direction orthogonal to the water surface of the water channel as a rotation center, and a blade unit provided at least in one radial direction of the circular rotating body. And when the blade portion moves from the upstream side to the downstream side of the water flow in the water channel with the rotation of the circular rotating body, the blade portion is displaced to a position orthogonal to the direction of the water flow, and the blade portion When moving from the downstream side to the upstream side of the water flow in the water channel, the blade part moves to the downstream side of the water flow because the entire blade part is displaced to a position parallel to the water flow. The circular rotating body is rotated in a certain direction by utilizing the resistance received from the flow of water at the time, and this rotational force is provided in the power generation unit via the rotating shaft to transmit the generated electricity to the outside of the water channel. A water channel power generator.
