Automatic decontamination device for photovoltaic panels by light reflection method

Abstract

The invention provides an automatic decontamination device for photovoltaic panels by a light reflection method. A moving base is slidably mounted inside a shell, a magnet is arranged inside the outerside of the moving base, a corresponding coil is arranged on the outer side of the magnet and inside the shell, a brush head is fixedly mounted at the inner end of the moving base, a reflecting mirror is fixedly mounted on the inner side of the brush head, and a photoresistor is arranged on the position, at the inner of the shell, above the photovoltaic panels. When the photovoltaic panels are not cleaned for a long time and excessive dust and sundries are accumulated on the surface, sunlight penetrates through the photovoltaic panels and passes through the reflecting mirror to reach the photoresistor, so that the resistance value of the photoresistor connected to a circuit is adjusted, the strength of the transmitted light is small, the resistance value is small, the magnet is pushed when the magnetic field generated by the coil is larger than the tension of a spring, the movable base is driven to move inwards at the same time for decontamination, and therefore the purpose of automatic decontamination when the dust on the surface of the photovoltaic panels exceeds a certain amount is achieved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic panels, in particular to an automatic decontamination device for photovoltaic panels by means of light reflection. Background technique [0002] Solar photovoltaic panels are a new, non-polluting renewable energy source, and have been widely used at home and abroad. Most of the solar photovoltaic panels are placed outdoors, and the impact of daily dust and debris on photovoltaic panels is ignored during use. The impact of conversion efficiency, dust and debris directly reduce the amount of solar radiation received by the solar photovoltaic panel, and will cause the temperature of the photovoltaic panel to be too high, which will reduce the output power. [0003] At present, solar photovoltaic panels used outdoors cannot be decontaminated automatically when the dust on the surface of the photovoltaic panel exceeds a certain amount, which requires a large amount of labor. At the same time, when...

[0002] Solar photovoltaic panels are a new, non-polluting renewable energy source, and have been widely used at home and abroad. Most of the solar photovoltaic panels are placed outdoors, and the impact of daily dust and debris on photovoltaic panels is ignored during use. The impact of conversion efficiency, dust and debris directly reduce the amount of solar radiation received by the solar photovoltaic panel, and will cause the temperature of the photovoltaic panel to be too high, which will reduce the output power

[0003] At present, solar photovoltaic panels used outdoors cannot be decontaminated automatically when the dust on the surface of the photovoltaic panel exceeds a certain amount, which requires a large amount of labor. At the same time, when there is a lot of dust, it is easy to adhere to the surface of the photovoltaic panel, which is difficult to clean and affects The operating temperature inside the photovoltaic panel reduces the photoelectric conversion efficiency. Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic decontamination device for photovoltaic panels is provided by light reflection method, in order to achieve a more efficient practical purpose
