Description

A photovoltaic dust removal device based on dynamic electric field force

Technical field

The invention relates to the technical field of photovoltaic panel dust removal equipment, specifically a photovoltaic dust removal device based on dynamic electric field force.

Background technique

Photovoltaic stations are usually set up in areas with stable lighting and away from crowds, especially in areas with drought and little rain. However, the dust content in the air in the above areas is high, which leads to common dust accumulation on the surface of photovoltaic panels. Photovoltaic Dust accumulation on the panel surface will affect its power generation power and even produce hot spots, which will affect the service life of the photovoltaic panel. Therefore, photovoltaic panel dust removal is an extremely necessary and routine daily maintenance behavior in the operation of photovoltaic stations. The current cleaning methods of the photovoltaic panel surface mainly include Water washing and dry brushing methods, water washing will waste a lot of water resources, and will significantly increase the operating costs of power stations in water-scarce areas. Although the dry brushing method can effectively remove dust, it can easily cause damage to the surface of photovoltaic panels.

In view of the above current situation and shortcomings, a self-powered solar panel electrostatic precipitator device and method with the publication number "CN115532734A" in the prior art has been proposed. The device includes: a power module for providing DC high voltage; a solar panel as a lower electrode , the electrode inside the solar panel is connected to one end of the power module; the upper electrode, the upper electrode is arranged above the solar panel at a preset distance, and is connected to the other end of the power module to form a capacitor with the solar panel, using its connection with the solar panel. The non-uniform electric field between them polarizes the dust on the solar panel, and is affected by the dielectrophoretic force under the action of the non-uniform electric field, causing the polarized dust to break away from the surface of the solar panel. Combined with the effect of gravity, the electrostatic dust removal of the solar panel is completed. Therefore, there is no need to consume water, no need to rely on labor, no need for additional mobile devices, no need to add anything to the solar panel to achieve solar panel dust removal, and no requirements for humidity, wide application environments, simple power circuit, low power consumption Small and low cost.

However, the above-mentioned self-powered solar panel electrostatic dust removal device and method still have obvious defects during use: the above-mentioned device installs a dust removal module fixedly above the photovoltaic panel, and its laying area needs to be equivalent to the area of the photovoltaic panel, and it will cause damage to the photovoltaic panels. At the same time, although the above-mentioned device can achieve the desorption of dust on the surface of the photovoltaic panel, it still requires manual or additional cleaning mechanisms to clean the dust attached to the grid electrode, and the above-mentioned device is on the grid electrode. Before the dust is cleaned, it needs to be continuously powered on, which requires a large amount of electric energy. In summary, the above-mentioned device still has obvious shortcomings.
