Abstract
The utility model discloses a solar light collecting lens. The solar light collecting lens is characterized by comprising an enclosed casing and transparent liquid filled at an inner portion of the casing, wherein the casing has two light collecting faces, the light collecting faces project outwards, each light collecting face is a Fresnel lens, the casing is prepared by high-transparency synthetic glass or prepared by transparent polyolefin materials through one-piece injection molding, and the transparent liquid comprises water and alcohol. The solar light collecting lens is advantaged in that a structure is simple, manufacturing is convenient; the casing is formed by two light collecting faces projecting outwards, the inner portion of the casing is filled by the transparent liquid, the structure can have a same light collection effect as a convex lens, the solar light collecting lens has simpler technology and greatly-reduced manufacturing cost; through the Fresnel lens, manufacturing cost is further reduced, a disadvantage of a poor light collecting effect of the lens is settled, and thereby a solar utilization rate is improved.
Description
Technical field
The utility model relates to a kind of lens, is specifically related to a kind of sun power collector lens, belongs to technical field of solar.
Background technology
Sun power is a kind of cleaning, efficiently and never depleted new forms of energy, and along with the continuous development of heliotechnics, each country is also more and more higher to the demand of sun power.But in field of photovoltaic power generation, the application of sun power can not get a large amount of popularizations always, and most important reason is low excessively to the utilization ratio of sun power.
In the prior art, the main method that improves solar energy utilization ratio is carried out the optically focused of sun power with regard to the mode that is to use lens, but because lens diameter is big, focal length is far away, spotlight effect is also bad; In addition, the manufacturing cost height of lens, complex process have more limited the application of sun power in field of photovoltaic power generation.
The utility model content
Be to solve the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of cost is low, the optically focused performance is good, the collector lens high to solar energy utilization rate.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of sun power collector lens is characterized in that, comprising: the shell of sealing, and the transparency liquid that fills up aforementioned enclosure; Aforementioned shell has two caustic surfaces, and aforementioned caustic surface is to outer lug, and each caustic surface is a Fresnel Lenses.
Aforesaid sun power collector lens is characterized in that, aforementioned shell is made by the transparent organic glass of height, is perhaps made by transparent polyolefine material.
Aforesaid sun power collector lens is characterized in that, aforementioned polyolefin shell adopts integrated injection molding.
Aforesaid sun power collector lens is characterized in that, aforementioned transparency liquid comprises: water, alcohol.
Aforesaid sun power collector lens is characterized in that aforementioned shell is oblate spheroid, and diameter is 500-600mm; Perhaps, aforementioned shell is rectangular or square shaped.
Aforesaid sun power collector lens is characterized in that, the thickness of aforementioned shell is 1-2mm.
Usefulness of the present utility model is: simple in structure, and convenient the manufacturing; Shell is made up of two caustic surfaces to outer lug, and solid transparency liquid, and this kind structure can reach the spotlight effect the same with convex lens, but technology is more simple, and manufacturing cost greatly reduces; Shell adopts Fresnel Lenses, has not only further reduced manufacturing cost, and has overcome the bad shortcoming of lens light gathering effect, thereby improved solar energy utilization rate.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model collector lens;
Fig. 2 is the cross-sectional view of collector lens among Fig. 1;
Fig. 3 is the structural representation of another specific embodiment of the utility model collector lens.
The implication of Reference numeral among the figure: 1-shell, 2-transparency liquid.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
See figures.1.and.2, sun power of the present utility model comprises with collector lens: the shell 1 of sealing, and the transparency liquid 2 that fills up shell 1 inside.Concrete, shell 1 has two caustic surfaces, and caustic surface is to outer lug, and each caustic surface is a Fresnel Lenses.
Collector lens of the present utility model, its manufacturing process is: at first make shell 1, stay an aperture (not shown) be used for to inject transparency liquid on the shell 1, treat that transparency liquid fills up shell 1 volume inside after, again shell 1 is sealed.This kind structure can reach the spotlight effect the same with convex lens, but technology is more simple, and manufacturing cost greatly reduces.
As a kind of preferred scheme, shell 1 is made by the transparent organic glass of height, not only has transmittance and spotlight effect preferably, and price low, be easy to machining.
As a kind of preferred scheme, shell 1 can also be made by transparent polyolefine material, not only cheap, high comprehensive performance, and machine-shaping easily.
More preferably, the polyolefin shell adopts integrated injection molding, production efficiency height.
In collector lens of the present utility model, shell 1 is solid transparency liquid 2, the effect of transparency liquid is the refraction sunshine, so no matter which kind of liquid it is, if transparent all passable, water and alcohol that preferred source is wide, cost is low.
For simplified structure, the convenient manufacturing, the shell of collector lens can adopt oblate spheroid, and it can also adopt comparatively regular shapes such as rectangle, square, with reference to Fig. 3.
Adopt oblate spheroid as if shell, the preferred 500-600mm of its diameter, convenient carrying and use.
In the utility model, the thickness of shell is 1-2mm.Thinner shell is conducive to collector lens and converges to more sun power, thereby improves solar energy utilization rate.
Collector lens of the present utility model can be used to make condenser, is used for aspects such as photovoltaic, photo-thermal power generation and central heating.
Need to prove that above-described embodiment does not limit the utility model in any form, all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
