Description

Mobile PV system

The present invention relates to a mobile PV system (photovoltaic system) with the features of the preamble of claim 1.

Generic mobile PV systems can be moved to areas where there are no stationary PV systems. Preferably, they are designed so that they can be made operational by unskilled auxiliary personnel. Such a PV system is evident from DE 10 2010 041 128 A1 and US 2013186450 A1. There, the PV panels are arranged in alignment with each other in the operating position. This has the disadvantage that the PV system does not efficiently utilize the solar irradiation power in the course of the sun. In addition, the power of the PV system may deposit depleting deposits on the horizontally oriented PV panels.

WO 2013/107569 A1 and US 2016056752 A1 disclose arrangements of PV modules with an angle of inclination between in each case two rows of panels. In WO 2013/107569 A1, adjacent panels for this purpose are to be arranged on a plastic construction formed integrally with a predetermined angle. Obviously, the plastic construction shown in WO 2013/107569 A1 can not be used in a mobile construction according to US 2013186450 A1, since otherwise the panels would not be collapsible accordion-like into a transport position.

In US 2016056752 A1 also a rigid substructure is provided, which predetermines a predefined angle. The object of the invention is to provide a generic PV system in which the problems discussed above do not occur or only diminished. This object is achieved by a mobile PV system with the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims. Because at least one limiting device is arranged between adjacent PV panels, which prevents the complete unfolding of the PV panels into an aligned arrangement, an arrangement of the PV system according to the invention in a so-called "east-west orientation" is possible, which over the As the individual PV panels in the operating position are at an angle with a horizontally extending background, there is a certain amount of self-cleaning and deposits that reduce the performance of the PV system can not, at least to such an extent build up as in the prior art.

Although Fig. 1 of US 2013186450 A1 already shows that an inclination of all panels can be selected together. Adjacent panels, however, do not enclose any angle of inclination with each other. Fig. 16 of this document shows angles of inclination between adjacent PV panels, but these are not produced by simple limiting devices arranged between adjacent panels, thus preventing complete unfolding of adjacent panels arranged movably to each other. Instead, a separate drive device (reference numeral 150) is provided for each panel, which is obviously associated with a much greater effort than providing simple limiting devices between adjacent panels. Whether a favorable inclination of adjacent panels relative to one another in an east-west orientation can be set in FIG. 16 is not disclosed.

Embodiments of the invention will be discussed with reference to the figures. In order not to affect the clarity, not all components are always provided with reference numerals.

Fig. 1 shows a mobile PV system 1 according to the invention in the transport position with a transport cover 12, which is designed here in the form of a container structure. Alternatively, the transport cover 12 could be provided in the form of a tarpaulin. The transport cover 12 can, depending on the desired means of transport, be standardized. be quite trained, z. B. for ship transport, for air transport, for land transport by truck or rail vehicle.

FIG. 2 shows the mobile PV system 1 shown in FIG. 1, wherein the transport cover 12 has already been removed so far that the individual components of the PV system 1 are accessible. The side walls of the container structure are mounted in the embodiment shown articulated on the platform 2 and were pivoted to a horizontal position shown here. In practice, the pivoting can take place until contact with the substrate or a support means is present. At the front pages existing covers were removed there. On one of the two end faces, a control device 13 designed here as a control cabinet can be seen, which enables the autonomous operation of the mobile PV system 1. It may include batteries, inverters and other electrical and electronic components and be provided with a connection device for delivering the generated electrical energy. At the other end there is a storage space for support feet 10. Below the PV panels 3 located in the folded transport position are a storage space for segments 9, which can be assembled into rails, as well as a further storage space for further accessories. The platform 2 has been aligned here so that the side walls of the transport cover 12 facing west or east and the control cabinet having end face located in the north. This requires an arrangement in the northern hemisphere. In the southern hemisphere, the control cabinet would have to be located in the south.

Fig. 3 shows the mobile PV system 1 shown in Fig. 2, wherein the segments 9 have been assembled into rails. The rails are based on the support legs 10 on the ground. The support feet 10 are height-adjustable to compensate for unevenness of the ground (here via threaded rods) and have on their surface facing the area a cup 1 1 for receiving ballast material (eg., Sand, stones, earth, etc.) on. It can also be seen that a drawbar 14 has already been fastened to a part of the supporting structure 7 (see Fig. 7), which allows the folding apart of the concertina-like PV panels 3, which are arranged on this part of the supporting structure 7. The unfolding can be done manually or by means of a motor vehicle. Unlike shown (two parts of the supporting structure 7 per side), all PV Panels 3 one side to be arranged on a common part of the support structure 7 and be unfolded together or it could be provided several parts or sections. Fig. 4 shows the mobile PV system 1 shown in Fig. 3, wherein all the PV panels 3 are shown in a position which is between the transport position and the operating position. In reality, in the present embodiment, it would be preferable to first unfold the PV panels 3 of a section or part of the support structure 7 only on one side and then turn to the remaining PV panels 3. For this purpose, one would use each of the drawbar 14 or use separate drawbars 14.

FIG. 5 shows the mobile PV system 1 shown in FIG. 4, wherein all the PV panels 3 are in the operating position. This is characterized by the fact that the PV panels 3 are not aligned with each other (not horizontal), but adjacent PV panels 3 form an angle α with each other and with the ground. The angle between a PV panel 3 and the horizontal may be in a range of about 10 ° to about 20 °. Adjacent PV panels 3 then enclose an angle α of about 160 ° to about 140 ° with each other.

Fig. 6 shows a detail view of FIG. 5, wherein the angle α between adjacent PV panels 3 are seen from here about 160 °.

FIG. 7 shows a further detailed view of FIG. 5, wherein four PV panels 3 have been hidden in order to allow the view onto two segments 6 of a part or section of the supporting structure 7 supporting the PV panels 3. Each segment 6 is designed here for receiving five PV panels 3 and consists of six struts which are articulated via joints 4 on transversely extending bars 19 and are connected via further joints 4 with the struts of the adjacent segment 6. Of course, the supporting structure 7 could also be designed differently.

FIG. 8 shows a further detail view of FIG. 5 in an upper region of adjacent segments 6, wherein it can be seen that one of the limiting devices 5, which completely unfolds the PV panels 3 into an aligned arrangement prevent, as a stop between the segments 6 (more precisely between the struts) is formed. The segments 6 are connected to each other by means of joints 4.

FIG. 9 shows a further detailed view of FIG. 5 in a lower region of adjacent segments 6, wherein it can be seen that one of the limiting devices 5, which prevent the complete unfolding of the PV panels 3 into an aligned arrangement, acts as a stop between the segments 6 and a lower hinge 4 is formed. Visible are also an opening 18 for connecting adjacent segments 9 of the rail and rollers 16, over which the segments 6 of the support structure 7 travel along the rails.

Fig. 10 shows a further detail view, but in a position of the PV panels 3 just before that of Fig. 5. The segments 6 are still to be moved until the openings 8 are aligned with each other and z. B. a bolt can be inserted through it, resulting in a further limiting device 5 results.

1 shows a detailed view of the PV system 1 shown in the preceding figures in the transport position, but with the transport cover 12 removed. It can be seen that the carriages carrying the rollers 16 - and thus the entire concertina-like arrangement of the PV Panels 3 are secured to each other by means of pins 20 disposed on the carriages for transport. It can also be seen that the PV panels 3 rest on rails 9 of rails arranged on the platform 2, to which, after removal of the transport cover 12, the further segments 9 can be fastened until the desired rail length has been reached.

FIGS. 12a and 12b show that at least one limiting device 5 can be formed as a traction means 17 (here in the form of a rod) connecting with one another as adjacent carriages.
