Photovoltaic device for street lamp

Abstract

The invention relates to the field of photovoltaics, in particular to a photovoltaic device for a street lamp. The technical problem of the invention is to provide a photovoltaic device for a street lamp. According to the technical scheme, the photovoltaic device for the street lamp comprises a bottom frame, a storage mechanism, a cleaning mechanism and a direction adjusting mechanism; the upper part of the bottom frame is connected with the storage mechanism; the upper part of the bottom frame is connected with the cleaning mechanism; and the storage mechanism is connected with the cleaning mechanism. When in use, four photovoltaic panels are automatically rotated and stacked together in sequence, so that the area of the upper surface of a photovoltaic block is reduced by a quarter, the force of strong wind on the photovoltaic panels is greatly reduced, the photovoltaic panels are prevented from being blown off by the strong wind, meanwhile, the photovoltaic panels with different heights are cleaned, dust accumulation is prevented from influencing the light energy utilization rate, and the direction of the photovoltaic panels is automatically adjusted, so that the photovoltaic block can always face the sunlight, and the light energy utilization rate is greatly improved.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a photovoltaic device for street lamps. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The key element of this technology is the solar cell. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by region, because the sun shines on the earth; photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need to consume fuel and erect transmission lines to generate electricity and supply power on site, and the advantages of short construction period.

Problems solved by technology

[0005] In order to overcome the existing technology, solar street lights do not need to lay additional cables, especially suitable for remote rural areas, mountainous areas and other situations that require large-scale laying of cables. Sunlight irradiates photovoltaic panels, thereby reducing the efficiency of converting light energy into electrical energy. At the same time, in remote mountainous areas, workers regularly clean photovoltaic panels with heavy workload and low efficiency. At this time, in order to improve efficiency, photovoltaic panels will set the layout to Very large, when the weather is cloudy and rainy, the strong wind will blow off the too large photovoltaic panel, which directly leads to the damage of the solar street lamp. The technical problem of the present invention is: to provide a photovoltaic device for street lamp
