Description
[technical field]
The present invention relates to the cleaning equipment field, especially a kind of self-operated type is to device for automatically removing dust on light receiving surface of solar product.
[background technology]
Its principle of solar photoelectric light-heat product is to be the power conversion of the sun heat energy and electric energy, therefore no matter be photoelectricity. or the photo-thermal product, there is a prerequisite its installation aspect, must be installed in outdoor roof in the open exactly. high-altitude or spacious place, to accept sunshine to greatest extent, effectively bring into play its maximum photoelectricity or photo-thermal conversion performance.So dust in the atmosphere. foreign material and some corrosive deposits will be at an easy rate attached to its surfaces.Especially the area of environmental condition difference, 1-2 month will be at the full dust of the surface cover of cell panel.Having a strong impact on its photoelectricity. the conversion efficiency of photo-thermal reduce its serviceability, even damage brings about great losses.Therefore, dated in the standard no matter solar panel dispatches from the factory have how high conversion ratio, keep effective conversion ratio of solar panel, must keep its cleaning surfaces not have covering.In case when solar panel is installed in high-altitude or roof, just can't in time clean to covering its surperficial surface dust dust and other impurities.If do not clean for a long time, just its service efficiency can reduce greatly, the life-span also just can not guarantee to reach the life-span when dispatching from the factory regulation.It below is the basic inquiry test of making.Can only reach 13%-16% by the photoelectric transformation efficiency laboratory experiment of the solar panel of present use is the highest, the dust foreign material adhere to its surface 1---do not clean in 5 months, conversion efficiency just can only reach 8-10%, also can cause local pyrexia and burns out if the leaf birds droppings is bonded at its surface.Also can bring serious potential safety hazard as suffering heavy snow to cover weight.Because of different its influences of area surroundings also can be different, the northern area of China, the sandstorm area that takes place frequently particularly, dust thickening gradually can have a strong impact on the absorptivity of solar panel to sunlight, and generated energy also can reduce gradually, therefore, need regularly to give the solar panel dedusting.Be installed in the solar panel of short position at present, as solar lawn lamp, solar energy floor-lamp etc., can be regularly by artificial dedusting, be installed in high vacancy solar panel, as solar street light, roof solar electric supply installation, dedusting is inconvenience very, and the solar panel automatics is a key issue of being badly in need of solution both at home and abroad.
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of self-operated type device for automatically removing dust on light receiving surface of solar product.
For achieving the above object, a kind of self-operated type of the present invention's design is to device for automatically removing dust on light receiving surface of solar product.It is characterized in that: it comprises the fixed mount 1 of a solar energy photoreceptor, and fixed mount is provided with parallel rail groove, and skin scrapes 8 for the T font, and the horizontal ends top has scroll wheel 2, be embedded in fixed mount the rail groove in; Skin is scraped and is provided with chute 5; With universal bearing 6 interlocks and be connected power arm 7, the other end of power arm 7 is that upper transfer gear 9 is fixed on solar energy and is subjected in the middle of tabula rasa 4 belows.Solar product is subjected to tabula rasa 4 below sides to be provided with thermal-arrest plate 19, thermal-arrest plate 19 connects heat pipe 17, heat pipe 17 is by being equipped with temperature-sensitive shape memory alloy spring 15 between thermal-arrest plate 19 ends and the promotion tooth bar 14, promote tooth bar 14 other ends back-moving spring 13 is housed, promote tooth bar 14 and form actuating mechanism with lower transmissioning gear 11 interlocks.Form interlinked mechanism with upper transfer gear 9 interlocks again.
The present invention compares with prior art, and is simple in structure, simple installation, and the comprehensive dust that removes need not power supply, and cost is low.It is flexible to adopt memory alloy spring can produce when variations in temperature, thereby produces stroke, cooperates composition promotion skin to scrape to move mechanism again with reset common spring and heat pipe, utilizes the temperature difference in daytime and evening to remove the dust of light receiving surface of solar product every day.
