[0023] Specific examples are given below.

[0024] See also Figure 1 - Figure 5 The utility model provides a cleaning structure for photovoltaic panels, including a pair of fixing bars 1, the fixing bars 1 are symmetrically arranged; a servo motor 11 is fixedly connected to the side wall of the fixing bar 1; a card slot 16 is opened on the side wall of the fixing bar 1; a moving block 12 is connected to the lead screw nut pair at the output end of the servo motor 11; a connecting block 13 is fixedly connected to the side wall of the moving block 12; a cleaning rod 14 is provided on the side wall of the connecting block 13; a cleaning cotton 15 is fixedly connected to the bottom of the cleaning rod 14. When working, since the photovoltaic panel is installed outdoors, its surface will be covered with a lot of dust after a long period of rest. Dust and impurities will affect the power generation effect of the photovoltaic panel, which needs to be cleaned. The staff will buckle the card slot 16 of the fixing bar 1 on the edge of the photovoltaic panel, and then install the cleaning rod 14 on the end of the connecting block 13. When the photovoltaic panel needs to be cleaned, the equipment is started. Under the drive of the servo motor 11, the moving block 12 will drive the cleaning rod 14 to move up and down, and then cooperate with the cleaning cotton 15 to complete the cleaning of the surface of the photovoltaic panel. Through the setting of the cleaning equipment, the cleaning automation is realized, and the cleaning of the photovoltaic panel can be realized at the same time, which effectively reduces the cleaning time and reduces the maintenance cost.

[0025] Further, such as Figure 1 - Figure 5 As shown, a pair of through holes 2 are provided at the bottom of the fixing strip 1; a pair of first springs 21 are fixedly connected to the inner side wall of the card slot 16; an extrusion plate 22 is fixedly connected to the end of the first spring 21; a pull rod 23 is fixedly connected to the bottom of the extrusion plate 22; the pull rod 23 passes through the through hole 2 and is fixed to the extrusion plate 22. During operation, due to the different thicknesses of different photovoltaic panels, gaps will appear when the photovoltaic panel is clamped in the card slot 16, resulting in poor setting and fixation. Through the provided clamping device, when fixing the equipment at the edge of the light board, the staff pulls the pull rod 23 to compress the first spring 21, and then clamps the photovoltaic panel between the extrusion plate 22 and the card slot 16, and then releases the pull rod 23. At this time, the first spring 21 no longer receives tension and will rebound, and then the equipment is fixed to the edge of the photovoltaic panel. Through the provided clamping device, the fixing effect of the equipment is effectively improved, thereby effectively improving the stability of the equipment operation and at the same time improving the scope of use of the equipment.

[0026] Further, such as Figure 2 and Figure 3 As shown, a pair of fixing grooves 3 are provided on the top of the cleaning rod 14; a pair of sliding grooves 31 are provided on the side wall of the cleaning rod 14; a second spring 32 is fixedly connected to the inner side wall of the sliding groove 31; a fixing pin 33 is fixedly connected to the end of the second spring 32; a fixing hole 34 is provided on the side wall of the connecting block 13; the fixing pin 33 is slidably connected to the inner side wall of the sliding groove 31. During operation, when the cleaning rod 14 is installed between a pair of connecting blocks 13, it is necessary to push the cleaning rod 14 up from the bottom of the connecting block 13 so that the end of the connecting block 13 enters the fixing groove 3. As the cleaning rod 14 is continuously pushed, the connecting block 13 will squeeze the fixing pin 33 into the sliding groove 31. When the cleaning rod 14 is pushed to be parallel to the connecting block 13, the second spring 32 will push the fixing pin 33 into the fixing hole 34 to complete the fixing of the cleaning rod 14. This step effectively simplifies the installation steps of the equipment by the staff, thereby reducing the difficulty of installing the equipment and effectively facilitating the installation and fixing of the equipment by the staff.

[0027] Further, such as Figure 1 - Figure 3 As shown, a sliding hole 4 is provided on the inner wall of the sliding groove 31; a lever 41 is provided on the inner wall of the sliding hole 4; the lever 41 is fixedly connected to the side wall of the fixing pin 33. During operation, when removing the cleaning rod 14, the staff holds the lever 41 and then moves the lever 41 from one end of the sliding hole 4 to the other end. When the lever 41 moves, the fixing pin 33 will be moved out from the fixing hole 34, thereby releasing the fixing of the cleaning rod 14. This step effectively facilitates the staff to disassemble and replace the cleaning rod 14, thereby effectively reducing the workload of the staff during disassembly.

[0028] Further, such as Figure 2 and Figure 3 As shown, a disassembly rod 5 is provided on the side wall of the fixing pin 33; the disassembly rod 5 is fixedly connected to the side wall of the fixing pin 33; a pull ring 51 is fixedly connected to the end of the disassembly rod 5. During operation, when separating the cleaning rod 14 from the connecting block 13, the staff can pull the pull ring 51 to pull the disassembly rod 5 out of the sliding groove 31. When the pull ring 51 is pulled, the fixing pin 33 will be pulled out of the fixing hole 34, and then the cleaning rod 14 can be separated from the connecting block 13, thereby completing the disassembly of the equipment, thereby effectively facilitating the staff to disassemble the equipment, and thereby effectively increasing the convenience of equipment maintenance.

[0029] Further, such as Figure 2 and Figure 3As shown, a scraper bar 6 is provided at the bottom of the connecting block 13; the scraper bar 6 is fixedly connected to the bottom of the connecting block 13. When working, when the cleaning rod 14 moves back and forth, the scraper bar 6 is provided, and the scraper bar 6 will directly contact with the photovoltaic panel, thereby scraping off impurities on the surface of the photovoltaic panel, and cooperating with the cleaning cotton 15 to further improve the cleaning effect of the equipment and reduce the residual dust and impurities on the surface of the photovoltaic panel.

[0030] Further, such as Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the slot 16 is provided with a rubber plate 7; the rubber plate 7 is fixedly connected to the bottom of the inner wall of the slot 16. During operation, the rubber plate 7 is provided to effectively reduce the situation where the fixing bar 1 over-extrudes the photovoltaic panel when being fixed, thereby reducing the damage of the equipment to the photovoltaic panel.

[0031] Working principle: Since the photovoltaic panel is installed outdoors, after a long period of static state, its surface will be covered with a lot of dust and impurities, which will affect the power generation effect of the photovoltaic panel and need to be cleaned. The staff will buckle the card slot 16 of the fixing strip 1 on the edge of the photovoltaic panel, and then install the cleaning rod 14 on the end of the connecting block 13. When the photovoltaic panel needs to be cleaned, start the equipment. Under the drive of the servo motor 11, the moving block 12 will drive the cleaning rod 14 to move up and down, and then cooperate with the cleaning cotton 15 to complete the cleaning of the photovoltaic panel surface. Through the setting of the cleaning equipment, the cleaning automation is realized, and the cleaning of the photovoltaic panels can be realized at the same time, which effectively reduces the cleaning time and reduces the maintenance cost. Due to the different thicknesses of different photovoltaic panels, when the photovoltaic panel is stuck in the card slot 16 When the device is fixed at the edge of the light panel, a gap will appear, resulting in poor setting and fixing. Through the provided clamping device, when fixing the device at the edge of the light panel, the staff pulls the pull rod 23 to compress the first spring 21, and then clamps the photovoltaic panel between the extrusion plate 22 and the card slot 16, and then releases the pull rod 23. At this time, the first spring 21 no longer receives tension and will rebound. Then the device is fixed to the edge of the photovoltaic panel. The provided clamping device effectively improves the fixing effect of the device, thereby effectively improving the stability of the device operation and the use range of the device. When the cleaning rod 14 is installed between a pair of connecting blocks 13, it is necessary to push the cleaning rod 14 up from the bottom of the connecting block 13 so that the end of the connecting block 13 enters the fixing groove 3. With continuous pushing The cleaning rod 14 and the connecting block 13 will squeeze the fixing pin 33 into the sliding groove 31. When the cleaning rod 14 is pushed to be parallel to the connecting block 13, the second spring 32 will push the fixing pin 33 into the fixing hole 34 to complete the fixing of the cleaning rod 14. This step effectively simplifies the installation steps of the equipment by the staff, thereby reducing the difficulty of installing the equipment and effectively facilitating the installation and fixing of the equipment by the staff. When removing the cleaning rod 14, the staff will hold the lever 41 and then move the lever 41 from one end of the sliding hole 4 to the other end. When the lever 41 moves, the fixing pin 33 will move out from the fixing hole 34, thereby releasing the fixing of the cleaning rod 14. This step effectively facilitates the staff to disassemble and replace the cleaning rod 14, thereby effectively The workload of the staff during disassembly is greatly reduced. When separating the cleaning rod 14 from the connecting block 13, the staff can pull the pull ring 51 to pull the disassembly rod 5 out of the sliding groove 31. When pulling the pull ring 51, the fixing pin 33 will be pulled out from the fixing hole 34, and then the cleaning rod 14 can be separated from the connecting block 13, thereby completing the disassembly of the equipment, thereby effectively facilitating the staff to disassemble the equipment, and then effectively increasing the convenience of equipment maintenance. When the cleaning rod 14 moves back and forth, by setting the scraper 6, the scraper 6 will directly contact the photovoltaic panel, and then scrape off the impurities on the surface of the photovoltaic panel, and cooperate with the cleaning cotton 15 to further improve the cleaning effect of the equipment, reduce the residual dust and impurities on the surface of the photovoltaic panel, and by setting the rubber plate 7,This effectively reduces the situation where the fixing strip 1 over-compresses the photovoltaic panel when being fixed, thereby reducing the damage to the photovoltaic panel caused by the equipment.
