Cleanable photovoltaic power generation device capable of continuously circulating in windy and dusty area

Abstract

The invention discloses a cleanable photovoltaic power generation device capable of continuously circulating in a windy and dusty area in the technical field of photovoltaics. The device comprises a photovoltaic panel which is fixed on amounting bracket, a cleaning assembly comprising a sliding rail fixed on the mounting bracket, a traction assembly comprising a concave bracket fixed on the sliding rail, and a moving assembly fixedly mounted on the movable block. In windy weather, the cleaning brush roller rolls from top to bottom along the surface of the photovoltaic panel to sweep away dust on the surface of the photovoltaic panel, and when the cleaning brush roller rolls to the bottommost end, the cleaning brush roller moves towards the upper-layer slideway of the sliding rail under the action of inertia and enables the supporting shaft to impact the positioning disc, the air flow introduced by the induced draft hose is thus discharged from both sides of the rectangular box body, the wind resistance of the rectangular box body is reduced to drive the rectangular box body to reset, so that continuous circulating rotation of the cleaning brush roller is realized by utilizing the wind resistance, the photovoltaic panel can still keep high power generation efficiency in a strong wind environment, and the risk of damage is reduced.

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
