Self-cleaning photovoltaic panel for street lamp

Abstract

The invention relates to a self-cleaning photovoltaic panel for a street lamp. The self-cleaning photovoltaic panel for the street lamp comprises a cleaning device and a power generating plate. The power generating plate is obliquely installed at the upper end of a lamp post of the street lamp. An exhaust groove is fixed to the upper edge of the power generating plate. The cleaning device comprises speed limiting belts, connecting rods and an air compressing cavity. The speed bumps are equidistantly laid on a road. The lower surfaces of the speed bumps are fixedly connected with a top plate of the air compressing cavity through the connecting rods. The top plate is connected with a bottom plate of the air compressing cavity through pressure springs. The air compressing cavity is in an airtight state, communicates with the exhaust groove through an air guiding pipe and is further provided with a special air inlet. According to the self-cleaning photovoltaic panel for the street lamp, the photovoltaic panel can be automatically cleaned according to traffic flow, and the service life of the photovoltaic panel is effectively prolonged.

Description

technical field [0001] The invention relates to a photovoltaic panel, in particular to a photovoltaic power generation panel installed in a street lamp system. 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, 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 failures, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on the alignment of power generation efficiency. First, surface pollution affects the transmittance of light, which in turn affects the surface of modules The amount of radiation received; second, the adhesion of dirt to the surface of...

[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 failures, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on the alignment of power generation efficiency. First, surface pollution affects the transmittance of light, which in turn affects the surface of modules The amount of radiation received; 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 ;Especially in traffic roads, passing vehicles are likely to raise the dust on the road, and the air above the road is filled with high-density small particles of dust, which are easy to gather on the photovoltaic panels; on the one hand, it affects the light transmittance of photovoltaic panels, On the other hand, it can cause hot spot effect; therefore, the problem of cleaning photovoltaic panels in street lighting systems becomes very serious
