Construction safety early warning device

The invention discloses a construction safety early warning device, and belongs to the technical field of early warning equipment, the construction safety early warning device comprises a base, a storage battery is embedded in the base, and a supporting rod is fixedly mounted on the top wall of the base. According to the scheme, the wind cup is arranged, when wind passes through the wind cup, thrust is applied to the wind cup, then the wind cup drives the rotating rod to rotate under the action of the thrust, the brush plate is driven to rotate through the mounting rod in the rotating process of the rotating rod, and bristles are driven to rotate in the rotating process of the brush plate to clean dust on the surfaces of the warning lamp and the solar panel; further, dust accumulation on the surface of the solar panel is effectively prevented from affecting the power generation efficiency of the solar panel, and it can be ensured that the warning lamp has enough electricity to work; and dust on the surface of
