[0002] Solar photovoltaic panels have been widely used in recent years as a clean, efficient and renewable energy source. However, in actual operation, the surface of solar photovoltaic panels is easily covered by pollutants such as dust, sand, bird droppings, rain stains, etc., especially in deserts, Gobi or high humidity areas, where the pollution problem is particularly serious. These pollutants will block sunlight from shining on the surface of photovoltaic panels, resulting in a significant decrease in photoelectric conversion efficiency, thus affecting the performance of the entire power generation system.

Limiting blocks 306 are fixed on the inner walls of the lower ends of the two boxes 3, and guide holes 307 are provided on both sides of the limiting blocks 306. The box 3 is arranged outside the driving component to prevent dust, dirt, etc. from adhering to the ball screw 305, which plays a protective role on the driving component and prolongs its service life; the two boxes 3 are provided with rectangular openings 301 on the side facing the solar photovoltaic panel 2, which facilitates the movement of the cleaning rod 4 on the surface of the solar photovoltaic panel 2. When the cleaning rod 4 reaches the position limited by the limiting block 306, the driving component drives the cleaning rod 4 to move in the opposite direction, thereby removing the dirt on the surface of the solar photovoltaic panel 2.

[0026] Further optimized solution, the driving assembly includes a motor 302 fixed to the upper end of the box body 3, the output shaft of the motor 302 is fixedly connected to one end of the ball screw 305, the other end of the ball screw 305 is rotatably connected to the limit block 306, and the ball screw 305 passes through the slider 303 and is threadedly connected to the slider 303. The motor 302 drives the ball screw 305 to rotate, and the ball screw 305 is threadedly connected to the slider 303, thereby driving the slider 303 to slide along the ball screw 305, and the slider 303 drives the cleaning rod 4 to move to complete the cleaning work; the motor 302 reverses to drive the cleaning rod 4 to move in the opposite direction, and the reciprocating movement of the cleaning rod 4 realizes the cleaning of the surface of the solar photovoltaic panel 2.

[0027] In a further optimized solution, a position sensing block 304 is provided on the side of the slider 303 facing the limit block 306. The motor 302 drives the slider 303 to reach the position of the limit block 306, the position sensing block 304 feeds back a signal to the motor 302, the motor 302 reverses and drives the slider 303 away from the limit block 306, when the slider 303 reaches the position of the motor 302, the position sensing block 304 feeds back a signal to the motor 302, the motor 302 reverses and drives the slider 303 to slide toward the limit block 306, thereby realizing the reciprocating motion of the cleaning rod 4.

[0030] In a further optimized solution, the upper end of the box body 3 is fixed and connected to the water pipe 5, and the left side of the water pipe 5 passes through the box body 3 and is fixedly connected to the hose 502. Water is sprayed onto the surface of the solar photovoltaic panel 2 through the water pipe 5 in cooperation with the nozzle 501, thereby realizing water cleaning of the cleaning device and enhancing the cleaning effect.

[0031] Further optimizing the scheme, one end of the hose 502 is fixedly connected to the water pipe 5, and the other end of the hose 502 extends into the water storage tank 6. The hose 502 connects the water pipe 5 and the water storage tank 6, and the hose 502 is easy to deform, and the movable water storage tank 6 is placed in a suitable position.
