A cleanable photovoltaic power generation device with continuous circulation in windy and dusty areas

Abstract

The invention discloses a cleanable photovoltaic power generation device for continuous circulation in windy and dusty areas in the field of photovoltaic technology. It includes a photovoltaic panel, and the photovoltaic panel is fixed on a mounting bracket; rail; pulling assembly, including a concave bracket fixed on the slide rail; moving assembly, the moving assembly is fixedly installed on the movable block; the present invention makes the cleaning brush roll move from above to above along the surface of the photovoltaic panel when encountering strong winds Roll to the bottom to sweep away the dust on its surface. When the cleaning brush roller rolls to the bottom end, it moves to the upper slideway of the sliding rail through the action of inertia and makes the support shaft hit the positioning plate, so that the air passing through the suction hose The introduced wind flow is discharged from both sides of the rectangular box, and the wind resistance of the rectangular box is reduced, driving it to reset, realizing the continuous cycle rotation of the cleaning brush roller by using the wind resistance, so that the photovoltaic panel can still maintain high power generation efficiency in the windy environment. and reduces the risk of damage.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a cleanable photovoltaic power generation device for continuous circulation in windy and dusty areas. Background technique [0002] Photovoltaic: It is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. At the same time, the classification of solar photovoltaic power generation systems, one is centralized, such as large-scale Northwest ground photovoltaic power generation systems; the other is distributed, such as industrial and commercial enterprise factory roof photovoltaic power generation systems, residential roof photovoltaic power generation systems.

AI Technical Summary

Problems solved by technology

[0003] In some northern areas, it is dry all the year round, resulting in a lot of dust in the air, so that a large amount of dust will be deposited on the surface of the photovoltaic modules installed in this area, which will affect the power generation efficiency of photovoltaic panels. Most of the existing manual cleaning is done regularly. Considering the geographical environment where photovoltaic modules are installed, there are often strong winds in these areas, and the dust will be continuously deposited on the surface of the photovoltaic panels under the strong winds. Obviously, it cannot be cleaned manually, but if the dust is not cleaned in time, it will lead to power generation of photovoltaic panels. Efficiency, but also the problem of possible damage, for this reason, we propose a cleanable photovoltaic power generation device with continuous circulation in windy and dusty areas
