Description
Technical field
The utility model relates to a kind of device of solar generating, and the groove type solar arc surface optically focused thermal electric generator of especially a kind of designs simplification, cost economy belongs to the solar energy thermal-power-generating technical field.
Background technology
The slot light collection heat generating system is a hot generation technology of realizing commercialized running the earliest as one of basic pattern of solar heat power generation system.In the period of 1985-1991, LUZ company builds up 9 trough type solar power generation stations in succession in the California, USA desert area, total installation of generating capacity 353.8MW, and experienced four generation concentrating collector update, the cost of electricity-generating in final power station can be competed with conventional energy resource Thermal Power Station.This type systematic generally includes the grooved curved reflector that is installed on the support frame, is fixed near the vacuum heat collection pipe grooved curved reflector focal line by support frame, and drives the follower that the grooved curved reflector is followed the tracks of the sun by support frame.During work, the grooved curved reflector is focused to a focal line with the incident sunlight reflected, and the receiver that is placed on this focal line can absorb the sunlight heating working medium, produces high temperature and high pressure steam, the generating of pushing turbine group.
In said system, curved reflector adopts parabolic glass back mirror, and this mirror utilizes the low iron glass hot bending of high permeability to make.Owing to adopted mould-forming process during manufacturing, qualified manufactured goods precision control is better, and the catacaustic quality of curved reflector is higher, and regular shape is convenient to receive, and therefore can directly use vacuum heat collection pipe as its receiver.But on the other hand, with the technology more complicated that low iron glass hot bending is made parabolic glass back mirror, the required precision height causes technology controlling and process very strict, and percent defective is higher, the cost costliness; Simultaneously mould is in use because of standing often replacing of high temperature for a long time, and mould itself also cost is high.
Therefore, if can address the above problem, will further promote the commercial applications of hot generation technology, will advance of the popularization of slot type system greatly in China with a kind of simplification, economic way.
Summary of the invention
The purpose of this utility model is: the problem big at above existing parabolic glass bending moulding process difficulty, that required precision is high, yield rate is low, cost is expensive, thinking from simplification, economy, a kind of economical solar groove type arc surface thermal electric generator is proposed, thereby overcome the high and necessary weakness of using mould of glass bending moulding percent defective, guaranteeing further to reduce system cost under the Heat-collecting effect prerequisite.
In order to reach above purpose, the technical solution of the utility model is: a kind of economical solar groove type arc surface thermal electric generator, comprise the grooved arc surface speculum that is installed on the support frame, be fixed near the vacuum heat collection pipe grooved arc surface speculum focal line by support frame, drive the follower that grooved arc surface speculum is followed the tracks of the sun by support frame, wherein, described arc surface speculum is pasted by the surface, the metallic plate that applies or be equipped with efficient reflectorized material constitutes, both sides are fixed on the support frame, adjustable draw-off mechanism is housed on the described support frame, and described draw-off mechanism is fixedlyed connected with at least one place, metallic plate middle part by securing member.
Because 3 can determine a circular arc, so pass through 3 adjusting draw-off mechanism, can make metallic plate produce distortion, form required arc surface by its amount of deflection.As a result, need not to rely on brittle glass and hot bending, manufacturing process is simplified greatly, and cost significantly reduces.
The utility model rationally utilizes good distortion of metal material itself and extension performance, by draw-off mechanism metallic plate is made required grooved arc surface.During practical application, can adopt simple, economic nut-screw governor motion as draw-off mechanism, regulate the curvature and the reverberation direction of metallic plate, regulate fixing this shape that keeps in the back that puts in place, thereby abandoned the conventional method of development particular mold compression moulding, be more suitable for economical production.
In addition, can adopt two metallic plates of symmetrical distribution to make up the arc surface speculum, can make the light that incides on every group of metallic plate more near paraxial rays like this, focusing effect is better, and the focal line that obtains is more regular, more concentrated.
