Abstract
The utility model discloses a trough-type paraboloid solar concentrator comprising an optical concentrator trough-type paraboloid bracket and planar reflecting mirrors with widths slightly smaller than the projection width of a receiver, and the reflecting mirrors are sequentially fixed on the trough-type paraboloid bracket. Since the bracket takes a parabolical shape, incident parallel sunlight can be focused; and light-focusing power generation or heat-concentration power generation can be realized only when the planar reflecting mirrors with the widths slightly smaller than the projection width of the receiver (a collector tube or a photovoltaic cell) are fixedly laid on the trough-type paraboloid bracket sequentially for performing line focusing to sunlight, the receiver is mounted right above the paraboloid bracket, and the height and the focal distance are ensured to be in accordance with each other. The solar concentrator has the advantages of simple structure, good stability, low cost, convenience in production, installation and further maintenance, and no requirement for a one-piece curved surface glass reflecting mirror, which is difficult to produce and high in cost. The solar concentrator is suitable for mass production and application, and can effectively promote the development of light-focusing power generation and heat-concentration power generation through utilizing solar energy.
Description
Technical field
The utility model relates to a kind of apparatus for utilization of solar energy with solar, is specifically related to the existing improved groove type paraboloid solar concentrator of linear solar concentrator.
Background technology
Trough type solar power generation is to realize commercialized running the earliest, at present a kind of hot forms of electricity generation of installed capacity maximum.But owing to reasons such as cost height, processing difficulties, foreign technology blockades, major equipment condenser, thermal-collecting tube etc. cause China's solar energy thermal-power-generating project development more slow in all not large-scale productions of China.Using at present more linear solar concentrator has two kinds, and one, glass bending makes parabolic shape glass as reflecting surface, this catoptron is effective, long service life, but technology more complicated, accuracy requirement height, and technology controlling and process is very strict, the cost costliness; Two, adopt film silver-plated or that aluminize to cover on the parabolic type curved surface, this catoptron is respond well, cost is low, but when using in the more area of dust storm, the film reflecting surface is fragile, influences reflecting rate and heat build-up effect.
The device of realizing solar linear optically focused by simple plane is also arranged at present, and the utility model patent 200720010458.0 of bulletin just disclosed a kind of like this plane solar energy spotlight device on February 13rd, 2008.But this device needs the mounting plane catoptron to adjust skewback, when installed capacity is big, need expends a large amount of manpowers and remove to adjust skewback, not the extensive ability of using of tool.
Summary of the invention
The purpose of this utility model just provides that a kind of cost is low, simple in structure, easy for installation, the groove type solar condenser of long service life.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of groove type paraboloid solar concentrator, its structural feature is: comprise that condenser groove type paraboloid type support and width are slightly less than the plane mirror of receiver projection width, this catoptron is fixed on the groove type paraboloid type support successively.
Described groove type paraboloid type support shape satisfies parabolic equation
,
It is focal length; Described plane mirror width is slightly less than the projection width of receiver, and laying is fixed on the groove type paraboloid type support successively; Described receiver can be the thermal-collecting tube that is used for solar energy thermal-power-generating or intensification, also can be to be used for the concentration solar generating photovoltaic cell; Described receiver equals focal length to the distance of groove type paraboloid type carriage center
Compared with prior art, because the parabolic shape of this support own possesses the function that the parallel sunshine of incident is realized focusing, only need the plane mirror that width be slightly less than receiver (thermal-collecting tube or photovoltaic cell) projection width laid successively and be fixed on the groove type paraboloid type support, sunshine is carried out line focus, receiver is installed in directly over the parabolic shape support then, height is consistent with focal length, can realize concentrating to generate power or heat build-up generating.The utility model is simple in structure, good stability, cost are low; Production, installation and convenient later maintenance avoid using the monoblock bend glass catoptron that the production difficulty is big, cost is high.Be fit to large-scale production and application, effectively promote the development of solar energy concentration generating and heat build-up generating.Groove type paraboloid solar concentrator of the present utility model can be produced in batches, only the strip plane mirror need be laid on groove type paraboloid type support successively and be fixed, and can realize line focus to the sunshine of parallel incident.This solar concentrator is manufactured simply, and with low cost, installation and maintenance convenience can realize large-scale production and application, and solar energy optical-thermal and photovoltaic application are played the effect of actively promoting.
