The invention discloses an automatic cleaning device for photovoltaic power station components, which includes a cleaning scraper, a steel wire rope, a fixed pulley, a movable pulley block, a cylinder, a pneumatic reversing valve and a pneumatic stroke valve. Each of the fixed pulleys is installed on the frame of the photovoltaic power station component. , the steel wire rope with the cleaning scraper fixed on it goes around the fixed pulley, and its end is connected to the piston rod of the cylinder through the movable pulley group, and the air-controlled reversing valve is connected to the fixed pulley through the air pipe. The cylinder is connected, and the pneumatic stroke valve located at the piston rod end of the cylinder is connected to the pneumatic reversing valve through a trachea, and is used to control the piston rod to drive the cleaning scraper to reciprocate through the wire rope; the structure of the invention It is simple, has high reliability and low failure rate. It can meet the performance requirements of component cleaning in harsh environments and the installation form of various component arrays. It can be directly applied to existing power stations and can automatically clean components, reducing the need for Clean costs and increase the power generation of photovoltaic modules.
Description
