Photovoltaic module protection structure

The invention discloses a photovoltaic module protection structure which comprises a mounting plate, a photovoltaic module body is fixedly mounted on the mounting plate, fixing plates are fixedly mounted on the mounting plate and located at the top and the bottom of the photovoltaic module body, and two sets of guide assemblies are arranged on the opposite sides of the two fixing plates. According to the photovoltaic module cleaning device, dust or bird droppings and other stains adsorbed on the surface of the photovoltaic module body are brushed and cleaned in a reciprocating manner through the cleaning brush, and water is sprayed to the surface of the photovoltaic module body in cooperation with the water spraying holes, so that the dust or bird droppings and other stains adsorbed on the surface of the photovoltaic module body are cleaned while being brushed; the cleaning effect on the photovoltaic module body is improved, a large amount of dust or bird droppings and other stains are prevented from being ad
