An automated cleaning control system for photovoltaic modules

Abstract

The present invention discloses an automated cleaning control system for photovoltaic modules, which includes a base station, two longitudinal tracks, and multiple transverse tracks. The two longitudinal tracks are longitudinally aligned with the base station, and the multiple transverse tracks are sequentially arranged on the left side of the two longitudinal tracks in the order from front to back. In the present invention, the photovoltaic panel is cleaned in the mode of flushing, rough washing, re-flushing, and fine washing. The cleaning effect is higher than that of traditional equipment. After the rough washing roller brush and the fine washing roller brush are self-cleaned, they are dried by a drying component, so that they can be kept in a very clean state. The sewage all flows to the sewage recovery tank, and after precipitation and overflow through the overflow plate, it is circulated by a return water pump. When the ferry returns to the base station, the first water tank is replenished with water through the return water pump and the return water pipe. During cleaning, after the cleaning vehicle returns to the ferry, it is wirelessly charged through the charging component, and at the same time, the second water tank is replenished with water through the water supply pipe and the electric control valve. The sewage is recycled, which is more environmentally friendly.

[0002] Dust can greatly affect the light absorption of photovoltaic modules. According to statistics, the loss can account for 5 - 8% or even more of the total solar power generation. Therefore, it is necessary to often clean the surface of solar panels at appropriate times to reduce dust accumulation and improve the efficiency of power plants. Generally, photovoltaic power plants have a large area. In the early days, manual cleaning was mostly used, which was inefficient, had a long cycle, and was costly. With the development of technology, technicians have proposed efficient and automated cleaning equipment. Tracks are set outside the photovoltaic panels, and the cleaning equipment is transported to the tracks through a ferry device to clean multiple rows of photovoltaic panels. Multiple sensors are used for positioning and distance measurement on the cleaning equipment, the tracks, and the ferry device. The cleaning equipment is equipped with a walking device driven by a motor, and a dust-sweeping roller driven by a motor is also provided, which is more efficient than the previous manual cleaning method.
