When encountering rainy weather, rainwater flows into the water collecting box 3 at the bottom along the photovoltaic panel 2, and flows into the water collecting box 4 through the return pipe 302. When it is necessary to clean the surface of the photovoltaic panel 2, start the water pump 406, and transport the water in the water collecting box 4 to the cleaning rack 5 through the first water supply pipe 405 and the second water supply pipe 407, and spray it out through the water spray port 503. At this time, move the cleaning rack 5, and the bottom brush head 502 can clean the photovoltaic panel 2, and the water flows from the bottom into the water collecting box 3 and can be used repeatedly. The device can quickly and effectively clean the photovoltaic panel 2, reduce the cost of manual cleaning, and the water can be recycled to reduce the cost of water use.
