The utility model relates to photovoltaic support technical field provides a angle adjustable desert area photovoltaic support subassembly, including fixed plate, the top inlay of fixed plate has solar photovoltaic board. The utility model discloses be provided with cleaning structure, under the action of movable rod, the stability of movable plate movement has been strengthened, the movable plate after moving drives the scraper to descend, makes the bottom of scraper closely fits the surface of solar photovoltaic board, fixed plate, first
fixed frame and second
fixed frame, when the mobile seat moves on the outside of
threaded rod, the mobile seat will drive the top plate to move through the connecting seat, under the action of protective curtain, prevent sand and dust from entering the inside of first
fixed frame and second fixed frame, the top plate after moving will drive the scraper to uniform speed scrape and sweep the surface of solar photovoltaic board, fixed plate, first fixed frame and second fixed frame, under the action of protective layer, can prevent desert fine sand
electrostatic adsorption, cohere scraper to solve the power generation efficiency attenuation problem under the wind sand environment.
