Self-cleaning photovoltaic traffic lights

Abstract

The invention relates to a self-cleaning photovoltaic traffic lamp. The self-cleaning photovoltaic traffic lamp comprises a lamp pole, a lamp body and a photovoltaic panel. The photovoltaic panel is obliquely installed at the upper end of the lamp pole. The lamp body is electrically connected with the photovoltaic panel. A ventilation channel is arranged on the axial direction of the lamp pole. A ventilation hole communicated with the ventilation channel is arranged at the center of the photovoltaic panel. A protective plate is arranged at the upper surface of the photovoltaic panel. An air guiding fan is fixedly embedded in the plate surface of the protective plate. The air guiding fan exactly faces the position of the ventilation hole. The protective plate can rotate relative to the photovoltaic panel. The bottom part of the lamp pole is also provided with an air inlet which is communicated with the ventilation channel. According to the self-cleaning photovoltaic traffic lamp, stable operation of the photovoltaic panel can be guaranteed for a long time and occurrence frequency of the hot spot effect can be effectively reduced so that maintenance cost can be reduced and low-cost and high-efficiency operation of the photovoltaic traffic lamp can be realized.

[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 will continue to raise dust. Compared with other places, photovoltaic panels used to supply traffic power are more likely to accumulate dust. Therefore, photovoltaic panels in street lights, traffic lights, etc. need frequent cleaning. Cleaning; this makes the maintenance cost of photovoltaic traffic lights high, which brings great obstacles to the promotion of photovoltaic traffic lights
