Automatic dust-preventing photovoltaic panel

Abstract

The invention discloses an automatic dust-preventing photovoltaic panel. The photovoltaic panel comprises a bottom frame, a bottom plate and a photovoltaic panel, wherein a wiping device and a detecting device are arranged on the bottom plate; the wiping device comprises two groups of chain wheels and chains, and is driven by a fourth motor; scrapers are fixedly arranged on opposite positions of the two chains; the detecting device comprises an infrared emitter and an infrared receiver; a slide rail is arranged on the bottom plate on the side of the infrared emitter, and a slide is arranged inthe slide rail in a sliding manner; a horizontal steering lever is arranged on the slide block in a rotating manner, is provided with the infrared emitter, and is connected with a fifth motor; a wheel driven by a sixth motor is arranged at the bottom of the slide block; when the slide block is on an arbitrary position of the slide rail, an infrared ray emitted by the infrared emitter along the surface layer of the photovoltaic panel enters the infrared receiver for infrared intensity detection. The photovoltaic panel can be used for automatically removing dust on the surface of the photovoltaic panel, preventing the hot spot effect, maintaining the power generation efficiency of the photovoltaic panel and prolonging the service life of the photovoltaic panel.

Description

Technical field [0001] The invention belongs to the technical field of photovoltaic power generation equipment, particularly an automatic dust-proof photovoltaic panel. Background technique [0002] With the deterioration of the environment and the deepening of human awareness of environmental protection, photovoltaic power generation, as one of the main green energy sources, is increasingly being used; photovoltaic power generation is used as solar power generation, and weather conditions are the biggest factor restricting power generation, followed by human control. In addition to avoiding losses caused by electrical equipment failures, the cleanliness of photovoltaic panels is also particularly important; the pollution on the surface of photovoltaic modules has a significant impact on the power generation efficiency. First, the pollution on the surface affects the transmittance of light, which in turn affects the modules. The amount of radiation received by the surface; second...

Problems solved by technology

[0002] With the deterioration of the environment and the deepening of human awareness of environmental protection, photovoltaic power generation, as one of the main green energy sources, has been applied more and more; photovoltaic power generation as solar power, the weather is the biggest factor restricting power generation, followed by human control In addition to avoiding losses caused by electrical equipment failure, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on its power generation efficiency. The amount of radiation received by the surface; second, the adhesion of dirt to the surface of the solar panel will form a shadow, which will generate a hot spot effect in the local area of ​​the photovoltaic module, thereby causing damage to the photovoltaic panel, affecting the power generation efficiency and shortening the life of the photovoltaic panel. Life expectancy; the traditional method is to regularly clean the dust on the photovoltaic panels manually, which is a heavy workload and wastes a lot of manpower
