Photovoltaic-panel surface cleaning device

Abstract

The invention discloses a photovoltaic-panel surface cleaning device. The photovoltaic-panel surface cleaning device is characterized in that the bottom end of each of a soap water tank and a clear water tank is connected to the entry end of a reversing valve through a soap water pipe and a clear water pipe, the exit end of the reversing valve is connected to a washing pipe located above one side edge of a photovoltaic panel, a plurality of washing spray heads are arranged on the tube wall of the washing pipe, a sweeping device is arranged on the photovoltaic panel, the sweeping device comprises a sweeping roller which is arranged right above the photovoltaic panel, the sweeping roller sleeves a connecting shaft, two sliding wire blocks are respectively fixedly connected to two shaft ends of the connecting shaft, a screw lead is in threaded connection with a threaded through hole in each sliding wire block, and output shaft ends of synchronous motors are fixedly connected to right rod ends of the screw leads. By the arrangement, the surface of the photovoltaic panel is sprayed and washed through soap water and clear water, dust and water spots on the surface of the photovoltaic panel are respectively removed by the aid of the brush end and the felt end, and the cleaning device is clean thoroughly in washing, continuous in operation, simple in structure and convenient in maintenance and use.

Description

technical field

[0001] The invention relates to a photovoltaic panel surface cleaning device, which is applied in the technical field of photovoltaic panel surface cleaning. Background technique

[0002] Since the beginning of this century, photoelectric conversion technology has developed rapidly. After the rapid increase in photoelectric conversion efficiency in the early stage, since it has gradually approached the theoretical limit value, the speed of research and development of breakthrough technologies has entered a stable period. In this case, the influence of other factors on the power generation efficiency and power generation capacity of the components is gradually highlighted. Among them, the effect of dust occlusion on components has gradually become an important research topic.

[0003] The greater the solar radiation of the photovoltaic panels, the higher the power generation of the entire solar cell system. However, since the photovoltaic panels are installe...
