Abstract
The invention discloses a preposed fisheye meniscus lens group condenser, which is a solar condenser in no need of tracking the sun. The condenser realizes sun tracking-free solar energy collection application by utilizing the characteristic of superwide field of view of a meniscus lens group with a fisheye structure and the condensation characteristics of a main condenser, and belongs to the field of solar collection application. The condenser consists of the meniscus lens group with the fisheye structure, the main condenser and a solar energy absorption part. As long as the sun is in the field of view of the meniscus lens group with the fisheye structure, sunlight can be incident into the meniscus lens group, enters the main condenser after being refracted by the meniscus lens group, and is reflected and condensed by the lateral surface of the main condenser and finally condensed onto the solar energy absorption part.
Description
Technical field
This invention relates to the solar energy collecting application, has invented a kind of solar concentrator of following the tracks of in unmatchful day that links and realize with the meniscus shaped lens group and the main concentrator of flake structure.Utilize the ultra wide visual field angle characteristic of the meniscus shaped lens group of flake structure; The meniscus shaped lens group optical emission exit of flake structure and main concentrator light entrance port link; Make concentrator can receive the sunlight of the visual field direction of comforting oneself, realize not having the sunlight of following the tracks of and assemble application.This technology is applied to assemble field of photovoltaic power generation, can realize the solar energy collecting photovoltaic generation of following the tracks of in unmatchful day.
Background technology
In solar energy collecting was used, wired gathering of common concentrating method and point were assembled two types, and the line method for congregating mainly contains the grooved reflecting surface of minute surface forms such as adopting plane, parabola, various U profiles with solar energy converging, formed one " burnt band "; Point is assembled methods such as mainly containing the light funnel that adopts paraboloidal mirror, minute surface to constitute, Fresnel lens, various convex lens and is realized converging, and forms one " focal spot ".
Because different time, sunshine, angle was also different, and the angle that gets into the sunlight of collector is different, and the position of solar energy collecting also is different.Use in order to realize assembling, the sunlight lens system adopts the day tracking mode usually, and line is assembled to be needed the day uniaxiality tracking; Point gatherings need be carried out twin shaft day is followed the tracks of, and through to the day tracking means, adjusts the attitude of collector with the variation of sun angle; Make sunlight accumulate on the absorbing surface all the time; Absorb guaranteeing, but the energy loss of the tracking accuracy of tracking means, tracking, device long term reliability variation etc., to influence the overall performance of solar energy utilization system.Though assemble utilization ratio so adopt the method that day is followed the tracks of to improve sunlight, also increased manufacturing, the operation and maintenance cost of sunlight lens system, influence system's long term reliability.
Summary of the invention
For overcoming since solar energy collection system to the day shortcoming brought of tracking means; The present invention proposes a kind of meniscus shaped lens group and joining method of main concentrator of utilizing the flake structure; In the meniscus shaped lens group of main concentrator fore device flake structure, main concentrator bottom connects with solar absorption parts (like solar module or heat absorption assembly).Utilize the ultra wide field-of-view characteristics of the meniscus shaped lens group of flake structure; The sunlight of wide visual field direction also can get into; Then from the optical emission exit outgoing of the meniscus shaped lens group of flake structure; Through the gathering of main concentrator, finally accumulate on the solar absorption parts of bottom, thereby make lens system need not day is followed the tracks of again.
This invention is used for the solar energy collecting photovoltaic; Master-plan such as Fig. 1, the upper end is the meniscus shaped lens group with flake structure of ultra wide visual field, its meniscus shaped lens 1 by one group of flake structure is arranged in order according to common primary optical axis to be formed; The lower end is the sunlight exit portal of the meniscus shaped lens group of flake structure; Being complementary with the light entrance port of main concentrator 2 connects, and main concentrator bottom is a solar module 3, and it is an electric energy with transform light energy.
Main characteristic of the present invention
The characteristics of the ultra wide visual field of the meniscus shaped lens group of flake structure are used for solar energy collecting use, realize not having the solar energy collecting of following the tracks of and use, this concentrator can be used for solar energy collecting photovoltaic application and other application.
Benefit of the present invention and application prospect
This invention has proposed a kind of solar concentrator that need not the day tracking, uses the solar concentrator of the type, need not day is followed the tracks of, thereby has reduced solar energy collecting application system working service cost, has improved system's long term reliability; The light signal that this invention also can be applicable to other receives the field, realizes need not the light signal receiving system of tracking means.
