Grid cleaning device

The utility model provides a grating cleaning device which comprises fixing plates, a brushing mechanism and a driving mechanism, and the two fixing plates are arranged on the two sides of a grating in the width direction in parallel; the two brushing mechanisms are arranged on the two sides of the grating in the thickness direction correspondingly. The brushing mechanism comprises a sliding plate, a rolling brush and a driving wheel; the sliding plate is slidably installed on the fixing plate in the length direction of the grating. The rolling brush and the driving wheel are rotatably mounted on the sliding plate, and the driving wheel is tangent to the grating and a brush body of the rolling brush; the driving mechanism can drive the two brushing mechanisms to slide in the length direction of the grating. The driving mechanism drives the driving wheel to roll on the grating through the sliding plate, and the driving wheel drives the rolling brush to rotate, so that the rolling brush and the grating move rel
