The first slider 10 is fixed to the inner wall of the U-shaped frame 3, and a first thread passes through the first slider 10. The first lead screw 11 has a cavity 12 on the M-shaped frame 2. The bottom end of the first lead screw 11 extends into the cavity 12 and is provided with a first bevel gear 13. A first motor 14 is provided on one side of the M-shaped frame 2. The output shaft of the first motor 14 extends into the cavity 12 and is provided with a second bevel gear 15. The second bevel gear 15 meshes with the first bevel gear 13. Through a simple rinsing and wiping structure, it is convenient to simultaneously rinse and wipe the dust attached to the surface of the photovoltaic panel, effectively improving the cleaning effect and ensuring the power generation efficiency of the photovoltaic panel. The U-shaped frame 3 also includes two rectangular through slots 16. The rectangular through slots 16 pass through one side of the U-shaped frame 3. A second slider 17 slides through the rectangular through slots 16. 7 is fixed at one end of the diversion pipe 4. Two racks 18 are fixedly installed on both sides of the U-shaped frame 3. A second lead screw 19 is rotatably installed on one side of the second slider 17. A toothed block 20 is threaded on the second lead screw 19. The toothed block 20 meshes with the corresponding two racks 18. This arrangement facilitates the adjustment of the position of the brush 5, thereby ensuring that the brush 5 contacts the photovoltaic panel 1 and thus ensuring the wiping effect of the photovoltaic panel 1. Two limiting grooves are opened on one side of the M-shaped frame 2. Limiting blocks are slidably installed in the limiting grooves and fixed on the inner wall of the U-shaped frame 3. The water pump 8 is provided with two water guide pipes, which are respectively connected to the water tank 7 and the diversion pipe 4. By setting the limiting... The system includes a positioning groove and a limiting block to facilitate the positioning of the U-shaped frame 3. A first limiting rod is fixedly installed in the limiting groove, and the first limiting rod slides through the corresponding limiting block. By setting the first limiting rod, the limiting block is easily positioned. A circular hole passes through the sliding groove 9 and the chamber 12, and the first lead screw 11 rotates through the circular hole.

[0034] The working principle of this utility model is as follows: In use, the water pump 8 is first turned on, drawing water from the water tank 7 and supplying it to the distribution pipe 4. The water in the distribution pipe 4 is sprayed onto the photovoltaic panel assembly 1 through multiple angled nozzles 6. Then, the first motor 14 is turned on, and its output shaft drives the second bevel gear 15 to rotate. The second bevel gear 15 drives the first bevel gear 13 to rotate, which in turn drives the first lead screw 11 to rotate. The first lead screw 11 drives the first slider 10 to slide and descend within the slide groove 9, causing the U-shaped frame 3 to slide and descend on the M-shaped frame 2 and the photovoltaic panel assembly 1. Simultaneously, the U-shaped frame 3 drives the distribution pipe 4 to descend, and the multiple angled nozzles 6 on the distribution pipe 4 continuously spray water to rinse the photovoltaic panel assembly 1 during the descent. At the same time, the distribution pipe 4 drives the brush 5 to wipe the rinsed photovoltaic panel assembly 1, effectively removing dust. This design facilitates the removal of dust adhering to the surface of the photovoltaic panel. The simultaneous rinsing and wiping operation effectively improves the cleaning effect and ensures the power generation efficiency of the photovoltaic panel. When the brush 5 wears down and loses contact with the photovoltaic panel assembly 1, the two second lead screws 19 are rotated first, causing the toothed block 20 to be driven to disengage from the corresponding two racks 18. The fixation of the second lead screw 19 is released. Then, the second lead screw 19 is pulled, causing the second slider 17 to slide in the rectangular through groove 16 and approach the photovoltaic panel assembly 1. The two second sliders 17 drive the diversion pipe 4 to slide in the U-shaped frame 3, causing the brush 5 to be moved until the brush 5 contacts the photovoltaic panel assembly 1. Then, the two second lead screws 19 are rotated in the opposite direction, causing the toothed block 20 to be driven to re-engage with the two racks 18. The diversion pipe 4 and the brush 5 are fixed. This setting makes it easy to adjust the position of the brush 5, thereby ensuring that the brush 5 contacts the photovoltaic panel assembly 1 and thus ensuring the wiping effect of the photovoltaic panel assembly 1.
