The water pump 302 sprays the cleaning lotion in the water tank 301 from the nozzle 305 and sprays it on the surface of the photovoltaic panel, and the first motor 6 is used to control the cleaning lotion. 01 drives the screw rod 603 to rotate, and drives the cleaning roller 701 to move through the slider 604. Under the action of the gear 702 and the rack 704, the cleaning roller 701 rolls and wipes the surface of the photovoltaic panel. While the cleaning roller 701 moves, the scraping edge further wipes the surface of the photovoltaic panel, thereby increasing the cleaning force. When the first motor 601 is controlled to reverse, the scraper 705 and the cleaning roller 701 can be reset. While resetting, the scraper 705 and the cleaning roller 701 wipe the surface of the photovoltaic panel again.
