Self-acting device for automatically removing dust on light receiving surface of solar product

Abstract

The invention designs a self-acting device for automatically removing dust on a light receiving surface of a solar product, which is characterized by comprising a fixed mount 8 of a solar photoreceptor, wherein two sides of the fixed mount are provided with two parallel rail slots; the edges at two ends of a belt scraper 4 are provided with roller wheels which are embedded into the rail slots on two sides of the fixed mount; one end of the fixed mount 8 is provided with a heat collecting plate 2, and the middle of the heat collecting plate 2 is connected with a heat conduction pipe 1 which passes through a movable hole 5 of the belt scraper 4 to reach the other end of the fixed mount 8 and then is fixed by a fixed bush 9; a heat-sensitive shape memory alloy spring 3 is arranged between oneend of the heat conduction pipe 1 close to the heat collecting plate and the belt scraper 4; and a return spring 6 is arranged between the other end of the heat conduction pipe 1 and the belt scraper4. Compared with the prior art, the self-acting device has the advantages of simple structure, simple and convenient mounting, omni-directional dust removal, no power supply and low cost. The memoryalloy spring can extend when the temperature changes so as to generate a stroke, and then the memory alloy spring is matched with a common return spring and the heat conduction pipe to form a mechanism driving the belt scrapper to move, and thus the self-acting device can remove the dust on the light receiving surface of the solar product every day by using the temperature difference between day time and night.

Description

[technical field] [0001] The invention relates to the field of cleaning equipment, in particular to a self-operated automatic dust removal device for the light-receiving surface of solar energy products. [Background technique] [0002] The principle of solar photoelectric photothermal products is to convert the energy of the sun into thermal energy and electrical energy. Therefore, whether it is photoelectric or photothermal products, there is a prerequisite for installation, that is, it must be installed on the outdoor roof, high altitude or open space. In order to receive sunlight to the maximum extent, it can effectively exert its maximum photoelectric or photothermal conversion performance. In this way, dust, sundries and some corrosive substances in the atmosphere will easily attach to its surface. Especially in areas with poor environmental conditions, the surface of the battery board will be covered with dust within 1-2 months. Seriously affect its photoelectric and...
