Preferably, the brush body comprises a plurality of fixed plates uniformly arranged on the rotating shaft, a plurality of first elastic pieces arranged on the bottoms of the fixed plates, a brush plate arranged on the first elastic pieces and bristles arranged on the brush plate; can drive the fixed plate when the pivot rotates and rotate, and then drive the brush hair and rotate on the photovoltaic board surface to fall the snow brush on photovoltaic board surface, and promote the brush board through first elastic component, can carry out automatically regulated to the brush hair, brush hair wearing and tearing shorten also can keep laminating with the photovoltaic board.

Preferably, the bristles are distributed on the brush plate in an arc shape; it is better to be arc distribution and draw in the effect in, can better brush the snow.

Preferably, the bottom of the fixing plate is provided with a protection plate, the protection plate is provided with a sliding cavity, and the brush plate can slide up and down relative to the inner wall of the sliding cavity; prevent that snow from entering between brush board and the fixed plate, both guaranteed the adaptability of brush hair, can play the guard action to first elastic component again.

Preferably, the first driving assembly comprises a driving wheel arranged on the rotating shaft, a driving wheel, a first driving part driving the driving wheel to rotate, and a connecting belt used for connecting the driving wheel and the driving wheel.

Preferably, the second driving assembly comprises slide rails symmetrically arranged on two sides of the fixing frame, a connecting block arranged on the mounting plate, a sliding groove arranged in the slide rail, a screw rod arranged in the sliding groove and a second driving piece driving the screw rod to rotate, and the connecting block is provided with a threaded hole matched with the screw rod.

Preferably, the push plate is provided with a guide plate, and the guide plate is bent downwards in an arc shape; the guide plate can guide the accumulated snow sliding along the push plate to fall to the front of the moving direction of the push plate again, so that the accumulated snow is prevented from falling to the rear of the push plate, and the cleaning effect is ensured.

To sum up, this practicality chooses the snow on brush body clearance photovoltaic board top layer for use, has avoided the damage of photovoltaic board, and pushes away the most snow in upper strata to the great snow accessible push pedal of thickness, again by the clearance of the brush body, has guaranteed cleaning efficiency.
