Automatic cleaning device of surface of photovoltaic battery panel array

Abstract

The invention discloses an automatic cleaning device of the surface of a photovoltaic battery panel array. The device comprises a framework, a sliding block, a guide rail, a composite strip-shaped brush, a pressure sensor, a disc brush, a disc brush driving motor, a traction motor and a wire coil; a single chip microcomputer sends a signal to the traction motor, the traction motor drives the wirecoil to rotate, and a steel wire rope on the wire coil is connected with a dust removal mechanism; under the driving of the steel wire rope, the whole device moves on the guide rail, meanwhile, a discdriving motor drives the disc brush to rotate, and the surface of the battery panel is scrubbed so that dust removal can be more thoroughly carried out by the composite strip-shaped brush. Accordingto the device, a timing parameter is changed according to the ash accumulation degree of the solar battery panel and the surrounding environment of a photovoltaic power station, the surface of the battery plate can be automatically cleaned by the device; according to the device, energy consumption is relatively low, the device can replace manual operation to complete dust removal work of a large photovoltaic array; and the device is simple in structure, low in cost and high in stability, and is particularly suitable for the dust removal work of the large photovoltaic power station which is poor in water resources and short in labor force.

Problems solved by technology

[0002] Solar photovoltaic power generation is widely used in the development of new energy. In the entire solar photovoltaic power generation system, solar panels are one of the core components. If the surface of the solar panel array is covered with sand and other sundries, its photoelectric conversion efficiency will be reduced. Affects the performance of the entire solar photovoltaic power generation system. Studies have shown that if the dusty panel components on the surface are not cleaned for a long time, the power generation efficiency of the panel will be reduced by about 15%-20%.

Today's large-scale photovoltaic power stations are usually located in desert areas. Due to the relatively backward cleaning methods, the regular cleaning of photovoltaic arrays is relatively difficult. Therefore, it is extremely important to study efficient cleaning technologies and equipment to reduce the cost of photovoltaic power generation and improve the efficiency of dust removal. significance

At present, the existing domestic cleaning technology is mainly aimed at a single solar panel, with limited cleaning range and high cost, while the dust removal equipment specially developed for photovoltaic arrays has many defects in use, such as the developed high-pressure water jet cleaning device , which has a high degree of automation, but the waste caused by washing with a large amount of water is extremely inconvenient for the dust removal of photovoltaic power stations where water resources are scarce in desert areas
