A photovoltaic panel device capable of preventing wind and sand damage and guaranteeing working efficiency comprises a bottom plate. The upper side of the bottom plate is provided with a
wind speed device controlled according to a
wind speed, the left side of the bottom plate is fixedly connected with a front first supporting column and a rear first supporting column, and the upper sides of the first supporting columns are rotatably connected with first rotating blocks. A
centrifugal force is controlled through the
wind speed; a mechanical starting structure operates, a lifting column is driven to move downwards through a gear and rack principle, the photovoltaic panel is laid flat, the force of wind acting on the photovoltaic panel is reduced, the photovoltaic panel is effectively prevented from moving or toppling over, meanwhile, upper shielding cloth is spread out, a gravel
impact probability caused by wind and sand is further prevented, and in the spreading-out process of the shielding cloth, a roller of a cleaning
brush not only can clean impurities on the photovoltaic panel, but also can control a proper
water discharge amount through the speed of the roller in a
centrifugal force mode so that the cleaning work of the photovoltaic panel is guaranteed, meanwhile, the waste of
water resources is avoided, and the working efficiency of the photovoltaic panel in the next use process is guaranteed.
