[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, as the angle between the second photovoltaic panel and the first photovoltaic panel continues to decrease, when it decreases to a certain angle, and the angle between the second photovoltaic panel and the first support column also gradually decreases, the fourth transverse axis in the third guide groove slides into the fourth guide groove, and the fourth transverse axis corresponding to the first photovoltaic panel slides along the first guide groove into the second guide groove, and because the slopes of the fourth guide groove and the second guide groove are large and both show an upward trend, as the angle between the first photovoltaic panel and the second photovoltaic panel continues to decrease, the two fourth transverse axes carry the first balls at the corresponding ends and quickly climb upward along the second guide groove and the fourth guide groove, and in the process of climbing, carry the corresponding second support plates to slide in the direction close to their respective resistance blocks, and the sliding causes the first silicone rubber scraper fixed to the outer wall of the second support plate to start scraping impurities and dust on the surfaces of the first photovoltaic panel and the second photovoltaic panel along the motion trajectory.

The rotation of the second support plate will cause the second horizontal axis and the first silicone rubber scraper to rotate, and the rotation of the second horizontal axis and the first silicone rubber scraper will cause the first support plate to rotate. The first support plate will rotate along the inner wall of the second slide groove with the first horizontal axis. The setting of the second slide groove can ensure that the second horizontal axis and the first silicone rubber scraper will not fall off during the scraping process. The slight rotation causes the first silicone rubber scraper to be closer to the surfaces of the second photovoltaic panel and the first photovoltaic panel at this time, so that the scraping is cleaner.

[0020] In the present invention, since the outer contour of the second interfering bevel is matched with the outer contour of the first interfering bevel, the interference will cause the two second silicone rubber scrapers to gradually separate along the first interfering bevel.

During the separation process of the two second silicone rubber scrapers, the brush will be brought to scrape the surface of the first photovoltaic panel and the second photovoltaic panel horizontally, thereby further cleaning the surface of the first photovoltaic panel and the second photovoltaic panel.

[0048] In this embodiment: During the use of the existing photovoltaic power generation devices for buildings on the market, since photovoltaic power generation needs to be placed on the surface of the building for use, it is inevitable that certain debris and dust will accumulate on the photovoltaic panels on the surface under the wind and sun. If they are not cleaned in time, the photovoltaic power generation efficiency will be affected;

[0049] In order to avoid the above situation, during use, when the sun sets or it is rainy and there is no need to use photovoltaic power generation, the transmission cylinder 2 is started. During the start-up process of the transmission cylinder 2, its output end continuously pushes the first support column 4 along the inclined surface 8, pushing the first support column 4 to slide on the surface of the inclined surface 8 through the roller 6. Due to the inclined setting of the inclined surface 8, as the first support column 4 slides higher and higher along the surface of the inclined surface 8, the first slider 3 fixed at the output end of the transmission cylinder 2 gradually slides downward in the first slide groove 5 opened on the surface of the first support column 4 to adapt;

[0050] As the first support column 4 continues to slide and rise, the fixed plate 11 and the second photovoltaic panel 32 hinged to the end of the first support column 4 through the connecting rod 10 are continuously lifted, so that the second photovoltaic panel 32 is continuously rotated along the hinge with the first photovoltaic panel 12, and the rotation causes the angle between the first photovoltaic panel 12 and the second photovoltaic panel 32 to be continuously reduced, so that a folding trend is gradually formed between the first photovoltaic panel 12 and the second photovoltaic panel 32;

[0051] As the second photovoltaic panel 32 is continuously bent along the hinge with the first photovoltaic panel 12, at the same time, the fourth horizontal axis 28 of the outer wall and the first ball 31 are continuously sliding along the inner wall of the third guide groove 40. At this time, the sliding along the third guide groove 40 is to slide in coordination with the rotation of the second photovoltaic panel 32, and the sliding track is consistent with the movement direction of the second photovoltaic panel 32;

[0052] As the angle between the second photovoltaic panel 32 and the first photovoltaic panel 12 continues to decrease, when it decreases to a certain angle, the first ball 31 also slides along the inner wall of the third guide groove 40 to the intersection of the third guide groove 40 and the fourth guide groove 41. At this time, as the angle between the second photovoltaic panel 32 and the first photovoltaic panel 12 continues to decrease, the angle between the first photovoltaic panel 12 and the second support column 9 is also gradually reduced, and the angle between the second photovoltaic panel 32 and the first support column 4 is also gradually reduced. At this time, the fourth horizontal axis 28 in the third guide groove 40 slides into the fourth guide groove 41, and the fourth horizontal axis 28 corresponding to the first photovoltaic panel 12 slides along the first The guide groove 36 slides into the second guide groove 37, and because the slopes of the fourth guide groove 41 and the second guide groove 37 are relatively large and both show an upward trend, at this time, as the angle between the first photovoltaic panel 12 and the second photovoltaic panel 32 continues to decrease, the two fourth horizontal axes 28 carry the first balls 31 at the corresponding ends and quickly climb upward along the second guide groove 37 and the fourth guide groove 41, and in the process of climbing, carry the corresponding second support plates 27 to slide in the direction close to their respective abutment blocks 33, and the sliding causes the first silicone rubber scraper 21 fixed to the outer wall of the second support plate 27 to begin to scrape off impurities and dust on the surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 32 along the motion trajectory;

[0053] And when the fourth horizontal axis 28 slides into the corresponding second guide groove 37 and fourth guide groove 41, the fixed block 29 fixed to the outer wall of the fourth horizontal axis 28 and the first protrusion 30 will contact the contact plate 38 fixed to the outer wall of the second guide groove 37 and the fourth guide groove 41 on the movement trajectory. First, the first protrusion 30 will contact the second protrusion 39 at the end of the contact plate 38. Since the outer contours of the first protrusion 30 and the second protrusion 39 match, the first protrusion 30 will be forced to rotate with the fixed block 29 during the contact process, and the fixed block 29 will rotate with the fourth horizontal axis 28. and the second support plate 27 rotate, the rotation of the second support plate 27 drives the second transverse axis 16 and the first silicone rubber scraper 21 to rotate, the second transverse axis 16 and the first silicone rubber scraper 21 drive the first support plate 15 to rotate, the first support plate 15 drives the first transverse axis 14 to rotate along the inner wall of the second chute 13, the setting of the second chute 13 can ensure that the second transverse axis 16 and the first silicone rubber scraper 21 will not fall off during the scraping process, and the slight rotation makes the first silicone rubber scraper 21 more closely attached to the surface of the second photovoltaic panel 32 and the first photovoltaic panel 12, so that the scraping is cleaner;

[0054] And in the process of scraping, the first support plate 15 slides with the first horizontal axis 14 along the second slide groove 13, and at the same time, the first support plate 15 moves with the prismatic column 19, and the prismatic column 19 moves synchronously with the sliding frame 22. At this time, the second silicone rubber scraper 25 protruding from the outside of the sliding frame 22 moves synchronously with the sliding frame 22, and as the second silicone rubber scraper 25 moves, it will contact the outer wall of the interference block 33 fixed at the end of the first photovoltaic panel 12 and the second photovoltaic panel 32, and the first interference bevel 34 provided on the outer wall of the interference block 33 will conflict with the second interference bevel 35 provided at the end of the second silicone rubber scraper 25, and Since the outer contour of the second interfering bevel 35 matches the outer contour of the first interfering bevel 34, the interference will cause the two second silicone rubber scrapers 25 to gradually separate along the first interfering bevel 34. During the separation process, the second silicone rubber scrapers 25 will slide along the outer wall of the prismatic column 19 with the corresponding sliding frame 22, and will compress the first return spring 20 during the sliding process to facilitate the subsequent return. During the separation process, the two second silicone rubber scrapers 25 will scrape the surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 32 with the brush 26, and further clean the surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 32.

[0055] And because the second return spring 24 fixed on the surface of the second silicone rubber scraper 25 is fixed to the inner wall of the sliding frame 22, when the second support plate 27 rotates, the second silicone rubber scraper 25 will be more closely attached to the surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 32, and the close contact will cause the second silicone rubber scraper 25 to compress the second return spring 24;

[0056] As the angle between the first photovoltaic panel 12 and the second photovoltaic panel 32 becomes smaller and smaller, although they will not be close to each other, the scrapers on the two photovoltaic panels will eventually move to the uppermost end and collide with each other to block the gap between the photovoltaic panels, forming a storage and dust shielding effect on the surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 32. If the photovoltaic panel needs to be used, it is only necessary to reversely start the transmission cylinder 2 to make the output end of the transmission cylinder 2 move in the opposite direction, so that the second photovoltaic panel 32 and the first photovoltaic panel 12 can be unfolded again, and finally the first photovoltaic panel 12 and the first photovoltaic panel 12 form an aligned slope, which is convenient for the best angle of sunlight exposure;

[0057] It should be noted that: during the storage process of the device, as the angle between the first photovoltaic panel 12 and the second photovoltaic panel 32 gradually decreases, the first silicone rubber scraper 21 located on the surface of the first photovoltaic panel 12 and the second photovoltaic panel 32 will slide and scrape along the surface of their respective corresponding photovoltaic panels to scrape dust and debris from the photovoltaic panels, and in the process of scraping, the second silicone rubber scraper 25 in the horizontal direction will also scrape the surface of the photovoltaic panel, and in the process of scraping, the second silicone rubber scraper 25 and the first silicone rubber scraper 21 will be pushed closer to the surface of the photovoltaic panel for scraping.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
