Abstract
The utility model relates to a liquid filling lens with a wide angle. The utility model is composed of an upper shell of a convex lens, antifreezing transparent liquid and a flat reflector of a lens lower shell. The regulating range of the angle of a focal point of the lens is wide, and the application range of solar energy can be greatly enlarged.
Description
The utility model relates to a kind of reflective wide-angle liquid-filled lens, and its focusing range is wide, is particularly suitable for the sun power utilization.
Existing lens, comprise that utility application instructions (CN87214416U) and application for a patent for invention that Patent Office of the People's Republic of China announces openly illustrate disclosed liquid lens and liquid-filled lens in (CN1055608A), their light beam all is the opposite side emission to light source, and a plurality of signal-lens focus can not overlap.Thereby range of application is little, can not constitute lens group, can not make powerful solar-heating device.And the matrix parabolic mirror though power is big, can only be aimed at solar direction to use, and the range of adjustment of focus angle is little.
The purpose of this utility model is a kind of total-reflection type wide-angle liquid-filled lens of design, and not only focus point is in the same side of light source for these lens, and the range of adjustment of focus angle is big, and simultaneously, a plurality of simple lenses can constitute lens group.
The technical solution of the utility model is: the wide-angle liquid-filled lens is that the lens upper casing of convex surface, the transparent liquid that contains freeze-point depressant and lens lower casing plane mirror are formed by the para-curve surfaces of revolution or sphere.
Lens lower casing plane mirror can be by level and smooth clear sheet, aluminize or silver-plated total reflection film and protective finish constitutes.
The utility model wide-angle liquid-filled lens is owing to be reflective, thereby the focus point of lens is in the same side of light source, again owing to be plano-convex lens, thereby the reflection after focus point and the relative position of convex lens be constant, as long as regulate the direction of plane mirror, just can make the angle of focal point degree adjusted, range of adjustment is in hemisphere.Simultaneously, a plurality of simple lenses can coincide together focus, constitute lens group, and range of application greatly enlarges.
The embodiment that provides below in conjunction with accompanying drawing is further described specifically the utility model.
Fig. 1 is the utility model wide-angle liquid-filled lens diagrammatic cross-section, among the figure: 1, lens upper casing; 2, antifreeze transparent liquid; 3, lens lower casing plane mirror.
Fig. 2 is the structural representation of the utility model lower casing plane mirror 3.Among the figure: 4, level and smooth transparent sheet material; 5, aluminize or silver-plated total reflection film; 6, protective finish.
Fig. 3 is the utility model lens upper and lower shell method of attachment synoptic diagram, among the figure:
(a) middle-size and small-size lens: 1, lens upper casing; 3, lens lower casing; 7, bonding agent;
(b) large-scale lens: 1, lens upper casing; 3, lens lower casing plane mirror; 8, packing ring; 9, nut; 10, screw; 11, O-ring seal.
The related wide-angle liquid-filled lens of the utility model is that the lens upper casing (1) of convex surface, the transparent liquid (2) that contains freeze-point depressant and lens lower casing plane mirror (3) are formed by the para-curve surfaces of revolution or sphere as shown in Figure 1.
As shown in Figure 2, this lens lower casing plane mirror (3) by level and smooth transparent sheet material (4), aluminize or silver-plated total reflection film (5) and protective finish (6) formed (seeing accompanying drawing 2).Wherein aluminize or the thickness of silver-plated film (5) can be adjusted as required, but its reflectivity must not be lower than 91.5%, otherwise be not total reflection film just.This plated film (5) is the skin at the lens lower casing, avoids infringement for protecting it, and the outside preferably adds one deck protective finish (6), generally is to adopt ash paint to apply to form.
Among Fig. 1, the transparency liquid (2) that charges in the cavity that these lens are surrounded by upper and lower shell has multiple, can be any transparent liquid, also can be water, transparent wet goods, preferably water.In order to make lens also be mixed with freeze-point depressant in the transparent liquid, when subzero, do not freeze to guarantee temperature in outdoor utility.The transparent liquid that charges into mainly plays the medium effect.
The material of lens upper and lower shell can be the good glass of transparency, plastics or vibrin.Shown in Fig. 3 (a) and (b), the connection of lens upper and lower shell can be according to lens material and lens sizes in different ways.Large-scale lens housing is generally selected plastics or vibrin for use, and tightening is connected with nut (9) to adopt O-ring seal (11) to add screw (10), and (as Fig. 3 (b)) can adopt tackifier (7) to connect (as Fig. 3 (a)) in the time of must using glass.
When using wide-angle liquid-filled lens of the present utility model, after the parallel sunshine refraction of inciding lens upper casing (1) enters transparency liquid (2), inject again on the lens lower casing plane mirror (3), transparent liquid (2) is returned in refraction then, converges on the focus of lens convex surface top through lens upper casing (1) refraction.The focal position can be as required determines through calculating, and that is to say to obtain by the different designs to the curvature of lens upper casing, and the angle position of adjusting lens orientation back focus also changes thereupon, thereby makes lens have the wide wide-angle characteristic of reflect focalization angle.Utilize this wide-angle characteristic, a plurality of signal-lens focuses can be coincided together again, constitute lens group, improve power greatly.
Because lens focusing scope of the present utility model is wide, its purposes is enlarged, can in the many fields of national economy, be applied, especially more outstanding in sun power utilizes.Lens for example of the present utility model can be made into the solar cooker in the solar beam inlet chamber; Can be made into powerful solar energy high temperature stove, be used for hydrogen production by water decomposition and oxygen, handle the atomic energy waste material, reduce radiation hazard, the plate armour of the high temperature resistant exceptional hardness of melting new steel grade system tank etc.; Can be made into the equipment of treatment cutaneum carcinoma; Also can be made into sun power snow breaker etc.
