Cleaning method for self-cleaning photovoltaic panel of streetlamp

Abstract

The invention relates to a cleaning method for a self-cleaning photovoltaic panel of a streetlamp. The self-cleaning photovoltaic panel comprises a cleaning device and a power generating board, wherein the power generating board is arranged at the upper end of a lamp post of the streetlamp in an inclined mode; a gas exhaust slot is fixedly formed in the upper side edge of the power generating board; the cleaning device comprises a speed limiting belt, a connecting rod and a pressure gas cavity; the speed limiting belt is paved on a road at equal distance; the lower surface of the speed limiting belt is fixedly connected with a top plate of the pressure gas cavity through the connecting rod; the top plate is connected with a bottom plate of the pressure gas cavity through a pressure spring; the pressure gas cavity is in a gastight state, and communicates with the gas exhaust slot through a gas guide tube; and a special gas inlet is further formed in the pressure gas cavity. The photovoltaic panel can be automatically cleaned according to traffic flow, so that the service life of the photovoltaic panel is effectively prolonged.

[0003] 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
