Abstract
The utility model discloses a condensing lens of a solar power generation collector system, which comprises a spherical-paraboloidal reflective mirror composed of a plurality of small plastic condensing lens. Compared with the common solar condensing lens, the condensing lens of the power generation collector system has the advantages that: firstly, the spot-condensing mode is adopted for reflection, the condensation multiple is high, the condensation uniformity is high, so the condensation efficiency is high and the electric energy generated in the collector system is 2-3 times higher than a common photovoltaic battery; secondly, the condensing lens has high mechanical strength, anticorrosion and anti-aging; thirdly, the condensing lens has less thickness, small volume, light weight and is convenient in machining.
Description
Technical field
The utility model relates to the light-collecting lens that a kind of photovoltaic, photo-thermal system are used, the light-collecting lens of especially a kind of solar generating heat collecting system.
Background technology
At present, utilize successful, the most general mode of solar energy, when number photo-thermal translation type.It also is one type most effective during solar energy directly utilizes.Though the solar energy gross energy is very big,, bring very big difficulty for directly efficient utilization of solar energy because the energy density of solar energy is lower.The light-collecting lens thickness of making of glass was big in the past, weight is big, concentration ratio is low; Though the Fresnel light-collecting lens can weight reduction, difficulty of processing is big; Though common plastics eyeglass weight can alleviate, heat-resisting ability is poor, easy deformation.
The utility model content
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides the light-collecting lens of a kind of solar generating heat collecting system, and is simple for structure to realize making it have the phototranstormation efficiency height, assembles advantages such as easy to maintenance.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
The light-collecting lens of a kind of solar generating heat collecting system comprises spherical paraboloidal mirror surface, and described mirror surface is made up of at least 2 little light-collecting lens of plastics.The little light-collecting lens of plastics increases and decreases along with the size of minute surface area, and quantity is more.
The front shape of described mirror surface is near square, and its edge is circular arc.The maximum daylighting area of described mirror surface reaches 52 square metres.Wherein, it all is about 115mm that the size of the little light-collecting lens of plastics is generally length and width, and thickness is about 2mm, and the little eyeglass quantity of the plastics of Shi Yonging is just a lot of like this.
Described little light-collecting lens front shape is a square, and side view is spherical parabola.The back side at described little light-collecting lens is provided with guide pillar, and this guide pillar has 4, is provided with symmetrically and evenly.
Simple glass light-collecting lens characteristics are, by the curvature of control surface, utilize the light path official post light that produces to pool a bit, and the spotlight effect difficulty ensures.Cost is very high even be difficult on the technology and be achieved, and is also fragile even make, and weight is big.Little light-collecting lens of the present utility model is to adopt plastic production to become to have spherical paraboloidal little light-collecting lens.Therefore this plastics have certain elasticity and toughness, make little light-collecting lens mechanical strength height, corrosion-resistant, anti-aging.Little light-collecting lens is arranged in to pre-set by certain array or order to have on the spherical paraboloidal plastic stent, constitute mirror surface, its feature has: the material that at first is light-collecting lens can make the light of transmission vertically produce refraction, and the distribution of refractive index is radially reduced gradually, thereby realize smoothed and continuous the converging to a bit of emergent ray, thereby the light gathering efficiency height of this light-collecting lens.Next is to have the very big angle of accepting, and injects even sunlight tilts 5 °, after the refraction of this light-collecting lens optically focused, still focuses on the gallium arsenide solar cell assembly, guarantees high light concentrating times.Be that it has advantages such as thin thickness, volume be little, in light weight, easy to process once more
Because of according to the optically focused multiplying power, be assembled into big spherical parabolic mirror face by the little light-collecting lens of a plurality of spherical parabolas by the hot media technology of nanometer and collect sunlight.Under solar light irradiation, the spherical parabolic eyeglass collection sunlight reflect focalization of process improves (more than 1000 times) greatly with the luminous energy density of sunlight.The gallium arsenide solar cell conversion efficiency is improved, on the monocrystalline silicon of small size, obtain very high-temperature of big electric current and the sustainable generation of thermal-arrest.
Beneficial effect: the light-collecting lens of solar generating heat collecting of the present utility model system, compare with common Salar light-gathering eyeglass: at first, its optically focused is to adopt point type to assemble to carry out the light reflection, the light concentrating times height, the optically focused good uniformity, thereby the light gathering efficiency height, can produce common photovoltaic cell 2-3 times electric energy; Secondly, this light-collecting lens mechanical strength height, corrosion-resistant, anti-aging; Once more, be that it has advantages such as thin thickness, volume be little, in light weight, easy to process.

Embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As depicted in figs. 1 and 2, be the light-collecting lens of solar generating heat collecting of the present utility model system.The spherical parabolic minute surface 1 that this light-collecting lens is made up of a plurality of little light-collecting lens 2, the front shape of this spherical parabolic minute surface 1 is near square, but its edge is a circular arc.The maximum daylighting area of minute surface 1 can reach 52 square metres.
As shown in Figure 3 and Figure 4, be little light-collecting lens 2 of the present utility model.Its front shape is a square, and side view is spherical parabolic.Adopt plastic production, be provided with 4 guide pillars 3 at its back side, be provided with symmetrically, be used to snap in plastic stent.It all is 115mm that the size of the little light-collecting lens of plastics is generally length and width, and thickness is 2mm.
The light-collecting lens of solar generating heat collecting of the present utility model system is fastened on the support through nanometer heating agent technology by certain array by a plurality of little light-collecting lens 2, constitutes minute surface 1 integral body.This support is by uvioresistant complex intensifying plastic production.This have spherical paraboloidal little light-collecting lens and can produce very strong reflection light.Under solar light irradiation, through spherical parabolic little light-collecting lens 2 reflections, after the focusing of minute surface 1, the luminous energy density of sunlight is increased to more than 1000 times greatly, the gallium arsenide solar cell conversion efficiency is improved, on the monocrystalline silicon of small size, obtain very high-temperature of big electric current and the sustainable generation of thermal-arrest.Its optically focused is to adopt point type to assemble to carry out light reflection, light concentrating times height, optically focused good uniformity.Can produce common photovoltaic cell 2-3 times electric energy.
