[0003] After searching, a desert photovoltaic bracket disclosed in the publication number CN211429244U includes a shielding box, a power box and a photovoltaic bracket body. The photovoltaic bracket body includes a photovoltaic bracket and a bottom plate. The bottom plate is connected to the photovoltaic bracket by a hinged manner. The bottom of the photovoltaic bracket is connected to the piston rod of the cylinder in the power box to provide power for the photovoltaic bracket to rise or fall. A shielding box is set behind the photovoltaic bracket. When the photovoltaic bracket drops to a certain degree, the shielding plate in the shielding box moves forward to shield the photovoltaic panel on the photovoltaic bracket. The utility model has a simple structure and is easy to operate.

After the shielding box is reopened, the sand on it will fall onto the photovoltaic panel, thereby causing certain damage to the photovoltaic panel. In addition, the photovoltaic bracket lacks components for cleaning the surface of the photovoltaic panel, resulting in the sand falling on the photovoltaic panel affecting its photoelectric conversion efficiency.
