The cleaning driving member 33 drives the roller brush 31 to rotate on the cleaning frame 21 , thereby realizing the function of driving the roller brush 31 to rotate on the cleaning frame 21 .

[0037] refer to Figure 1 and Figure 3The clean water tank 41 is equipped with a clean water pump 42 that communicates with the rear sprinkler head 23. The water collection box 24 is connected to a circulating water tank 51. The circulating water tank 51 is equipped with a circulating water pump 52 that communicates with the front sprinkler head 22. Clean water is stored in the clean water tank 41. The clean water pump 42 is connected to the rear sprinkler head 23 via a clean water pipe 43. The clean water pipe 43 is connected to the rear sprinkler head 23 at the upper end of the rear sprinkler head 23. The circulating water pump 52 is connected to the front sprinkler head 22 via a circulating water pipe 53.

The filter plate 54 is located between the return water pipe 55 and the circulating water pump 52. The upper end of the filter plate 54 is tilted toward the circulating water pump 52 .

[0038] The lifting device includes a fixed sleeve 12, a movable sleeve 13, a connecting rod 14 and a driving mechanism. The fixed sleeve 12 is fixedly mounted on the vehicle frame 11, the movable sleeve 13 is slidably connected to the fixed sleeve 12, the ends of the connecting rod 14 are respectively fixedly connected to the movable sleeve 13 and the cleaning rack 21, and the driving mechanism is respectively connected to the vehicle frame 11 and the movable sleeve 13. The driving mechanism includes a fixed seat 15, a lifting drive member 16, a screw rod 17, a threaded sleeve 18 and an elastic member 19. The lifting drive member 16 is a motor. The fixed seat 15 is fixedly mounted on the vehicle frame 11, the lifting drive member 16 is mounted on the fixed seat 15, the screw rod 17 is rotatably connected to the fixed sleeve 12 and is fixedly connected to the output shaft of the lifting drive member 16, the threaded sleeve 18 is slidably connected to the movable sleeve 13 and is threadedly connected to the screw rod 17, and the ends of the elastic member 19 are respectively in contact with the threaded sleeve 18 and the connecting rod 14.

[0039] The height of the cleaning device is adjusted by the lifting device, and the position of the cleaning device is adjusted by the movable frame 11, so that the front water spray head 22 and the rear water spray head 23 are located above the photovoltaic panel, the first scraper 25 and the second scraper 26 are in contact with the photovoltaic panel, and the water collection box 24 is located below the photovoltaic panel surface. The clean water pump 42 pumps the clean water in the clean water tank 41 into the rear water spray head 23, so that the clean water is sprayed onto the photovoltaic panel for washing. The clean water sprayed onto the photovoltaic panel flows through the guide groove 27 into the water collection box 24, and then flows into the circulating water tank 51 as circulating water for storage. The circulating water pump 52 pumps the circulating water in the circulating water tank 51 into the front water spray head 22, and the circulating water is sprayed onto the photovoltaic panel through the front water spray head 22 for washing, thereby realizing the function of cleaning the photovoltaic panel through the cleaning device.

[0040] This embodiment has the following advantages:

[0041] During the movement of the frame 11, the photovoltaic panel is sprayed with water through the front water spray head 22 and the rear water spray head 23, and foreign matter and dirt on the photovoltaic panel are scraped off by the first scraper 25 and the second scraper 26, thereby effectively improving the cleaning effect of the cleaning device on the photovoltaic panel and achieving the advantage of better cleaning effect.

[0042] The roller brush 31 is driven to rotate on the cleaning rack 21 , and the surface of the photovoltaic panel is scrubbed by the roller brush 31 , thereby further improving the cleaning effect.

[0043] The cleaning agent nozzle 32 stores cleaning agent, and the cleaning agent is sprayed toward the roller brush 31 through the cleaning agent nozzle 32, so that the cleaning effect of the roller brush 31 on the photovoltaic panel can be improved by the cleaning agent, thereby further improving the cleaning effect.

[0044] The clean water pipe 43 and the circulating water pipe 53 are respectively connected to the upper ends of the rear sprinkler head 23 and the front sprinkler head 22, thereby ensuring that water can flush the surface of the photovoltaic panel from top to bottom, preventing insufficient water supply from causing the top of the photovoltaic panel to not be flushed, and playing a role in ensuring the cleaning effect.

[0045] The water recovery pipe 55 is in communication with the lower end of the water collecting box 24 , which reduces the water accumulation in the water collecting box 24 and facilitates the water in the water collecting box 24 to flow into the circulating water tank 51 through the water recovery pipe 55 .

[0046] The circulating water in the circulating water tank 51 is filtered by the filter plate 54 to prevent impurities entrained in the circulating water from entering the circulating water pump 52, thereby protecting the circulating water pump 52. It can also reduce the impurities entering the front water spray head 22 and improve the flushing effect of the front water spray head 22 on the photovoltaic panel.

[0047] The filter plate 54 is tilted so that a larger filter plate 54 can be placed in the circulating water tank 51 , which increases the water flow through the filter plate 54 , improves the water filtering efficiency of the filter plate 54 , and ensures that the circulating water pump 52 has sufficient water supply.

[0048] The movable sleeve 13 and the connecting rod 14 are driven by the driving mechanism to move vertically on the fixed sleeve 12, thereby realizing the function of driving the cleaning device to move up and down through the lifting device.

[0049] The lifting drive member 16 drives the screw rod 17 to rotate, and the screw rod 17 drives the threaded sleeve 18 threadedly connected to it to move vertically. The threaded sleeve 18 drives the connecting rod 14 and the movable sleeve 13 to move vertically through the elastic member 19, thereby realizing the function of driving the movable sleeve 13 and the connecting rod 14 to move vertically on the fixed sleeve 12 through the driving mechanism.

[0050] Since there is often a certain error in the installation height of the photovoltaic panel, the elastic member 19 is set so that the cleaning device can adapt to the change in the height of the photovoltaic panel and move up and down during the movement on the surface of the photovoltaic panel, and the elastic member 19 can continuously provide support force to the connecting rod 14 and the cleaning device, thereby adapting to the installation error of the photovoltaic panel.

[0051] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
