Description
Technical field
The present invention relates to a kind of solar generating heat collecting device, relate in particular to a kind of eyeglass of solar generating heat collecting device.
Background technology
At present, along with going from bad to worse of the in short supply day by day and global environment of traditional energy, various countries improve constantly for the attention degree of regenerative resource.And in many regenerative resources, have only the inexhaustible and not pollution of sun power, be the regenerative resource that has development potentiality most.The form of utilizing of sun power comprises photovoltaic, photo-thermal etc.
Along with the improving constantly and the reduction day by day of cell thickness of transformation efficiency, crystal silicon solar batteries is the main flow of occuping market gradually in recent years.But the fast development of crystal silicon battery has but caused interior critical shortage of the time once of silicon raw material, and silion cell produces a large amount of resource consumptions in process of production.Make that the cost of photovoltaic generation is high, and phototranstormation efficiency is less than 24%, amorphous and film efficiency of light energy utilization difference and increase environmental burden can not produce heat energy.Therefore, how to seek new material, new construction improves the sun power service efficiency, reduces cost, become heliotechnics obtain extensive popularization and application the problem that must solve.
And traditional Fresnel Lenses is a point focusing, point focusing is that sunshine is accumulated on the photovoltaic cell chip, cause the temperature of photovoltaic cell chip too high, aggravated the hot degradation effect of photovoltaic cell chip, and need degree of precision two dimension solar tracking tracking drive device, and the Fresnel Lenses usable floor area is bigger, and the photovoltaic cell chip area is less, overall space utilization factor deficiency, and there is the high acceptance angle that is difficult to realize, and light distribution is inhomogeneous behind the optically focused, and cooling heat dissipation makes the easily aging distortion of chip inadequately, the efficient decay.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this invention is to provide a kind of eyeglass of solar generating heat collecting device, to realize having self-cleaning function, the light transmission rate height is difficult for advantages such as aging distortion.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is:
A kind of eyeglass of solar generating heat collecting device, described eyeglass are flat shape or Arc lens; On the lower surface of described flat shape or Arc lens, be provided with the little ditch of linear pattern.The little ditch of described linear pattern is dentation or the little ditch of circular-arc linear pattern.
Described eyeglass adopts insertion slot type to be connected with the module casing.On module casing edge, be provided with groove, in installation process, after eyeglass and module casing aligned, insert groove and get final product, make eyeglass and module casing tighten mutually.
Described eyeglass can use separately for 1, also can be 2,3,4 or polylith, and the quantity and the generated energy of eyeglass are proportional, and eyeglass is The more the better in theory.When use surpassing 1 simultaneously, each piece eyeglass adopts laterally side by side, the parallel longitudinal mode connects, and is connected mutually at 2 eyeglasses that laterally connect side by side on the lower surface of part to be provided with reinforcement.
The upper surface of described eyeglass is provided with mechanical collector.Eyeglass influences the transmittance of eyeglass owing to the covering of dust or snow, and the generating efficiency of battery chip reduces or is zero.Utilize fly-ash separator, the dust or the snow of eyeglass are removed, make the generating efficiency of battery chip to improve greatly.The required power supply of mechanical collector provides for self power generation, timing or Remote cleaning works.
Eyeglass of the present invention adopts compound high light transmissive material to be made, the transmittance height, and high temperature resistant, xanthochromia, anti-aging not, the impact strength height, this point is different from general Fresnel Lenses.The lower surface of eyeglass main body is provided with little ditch of dentation linear pattern or the little ditch of circular-arc linear pattern, the quantity of the little ditch of linear pattern is many in the unit area, the cut-open view of the little ditch of eyeglass linear pattern is a dentation or circular-arc, such design can guarantee that directional light focuses on the battery chip that presets width, reduce the loss of transmittance, improve the output power of photovoltaic cell chip.Eyeglass adopts insertion slot type to be connected with the module casing, and is simple in structure, firm.Mechanical collector is set on eyeglass, and regularly snow is removed in the dust removal decontamination, has increased the eyeglass translucidus.Make the generating efficiency of battery chip to improve greatly.
Beneficial effect: the advantage of the eyeglass of solar generating heat collecting device of the present invention has: simple in structure, design ingenious, the transmittance height, high temperature resistant, xanthochromia is not anti-aging, the impact strength height; Lens surface is provided with mechanical collector, and regularly the dust removal decontamination has increased translucidus.Eyeglass adopts insertion slot type to be connected with the module casing, and is simple in structure, firm.
