Electromagnetic field dust removing device

Abstract

The invention relates to an electromagnetic field dust removing device comprising a plurality of parallel electrodes attached to the surfaces needing dust removal, a power supply used for supplying power to the electrodes, a pulse generator which is electrically connected between the power supply and the electrodes and dust monitoring controllers for detecting the surfaces needing dust removal, wherein the dust monitoring controllers are electrically connected with an intelligent controller, the intelligent controller is electrically connected with the pulse generator, the dust monitoring controllers are used for feeding detection signals back to the intelligent controller, and the intelligent controller outputs a first control signal to the pulse generator, automatically calculates pulse parameters according to the feedback results of the dust monitoring controllers and further outputs the signal to the pulse generator, and the pulse generator is used for applying different pulse signals to the electrodes to generate a varying electromagnetic field so that various types of dust can be removed.

Description

technical field [0001] The present invention relates to a device mainly used for dedusting surfaces such as solar cells, camera lenses, glass windows and the like. Background technique [0002] Large-area components, including solar arrays and heat-radiating surfaces, and optical equipment, mainly including glass windows, camera lenses and optical lenses, are very sensitive to dust. If the surface of the solar cell array panel is covered with a layer of dust, the power generation efficiency of the solar panel will drop sharply. This will seriously affect the power generation efficiency of solar power plants. According to literature, dust can cause 15-20% loss of power generation efficiency of solar panels. The same problem exists with the mirror in the reflective thermal radiation power generation system. If dust accumulates on the surface, it will also seriously affect the power generation efficiency of the entire power station, resulting in power loss. The dust on the su...
