Automatic washing device and method for solar photovoltaic component

Abstract

The invention provides an automatic washing device and an automatic washing method for a solar PV component and belongs to the technical field of solar PV power stations. The device comprises a cleaning system, a solution filter system, a solution circulating system and a control system, wherein the cleaning system comprises a flushing pipe and a flushing orifice; the solution filter system comprises a hydrops tank and a filter wool; the solution circulating system comprises a liquid storage tank, a solution supply pump, a solution circulating pump and a plurality of connecting pipelines, the liquid storage tank is connected with the solution supply pump, the solution supply pump is connected with the flushing pipe, one end of the solution circulating pump is connected with the hydrops tank, and the other end of the solution circulating pump is connected with the liquid storage tank; the control system comprises a pollution sensor and a controller, the controller is in wireless connection with or in wired connection with the pollution sensor, the pollution sensor is used for sending signals to the controller when the measured value of pollution exceeds a threshold value, and the controller is used for controlling the starting and cleaning processes of the solution supply pump and the solution circulating pump according to signals of the pollution sensor. Due to the adoption of the scheme, the technical problems of low degree of automation, incapability of automatic selection of solution and low solution utilization ratio can be solved.
