Abstract
A solar-energy cambered-surface reflector machinery bending molding method is disclosed. A flat mirror is placed on a supporting plane of a mirror holder. An adhesive medium, which is in an emulsifiable paste state at a normal temperature, is uniformly smeared on the supporting plane. The supporting plane of the mirror holder is a non-continuous pseudo cambered surface. A shape of the pseudo cambered surface is the same with the shape of the cambered-surface reflector to be manufactured. The flat mirror is attached tightly with the supporting plane through exerting a mechanical force. The method is simple and practical and the method can be used to manufacturing and molding at a normal temperature and under a normal pressure.
Description
Technical field
The present invention relates to a kind of manufacturing approach of globoidal mirror, particularly be used for the light collecting a kind of sun power cambered surface catoptron mechanical bend forming method of line.
Background technology
In the solar energy thermal-power-generating field, especially adopt in the light collecting hot generation mode of line, globoidal mirror is extensively adopted as solar concentrating system.In general, the manufacturing of this type of catoptron is formed by level crossing or flat glass distortion.Concrete processing technology can roughly be divided into two types: (1) high temperature thermal deformation: earlier glass heats is arrived soft state, then at mould interior heat bending deformation, then can select to carry out tempering and gain in strength, the globoidal glass after moulding row again plates mirror and sprays paint.This technology is with high costs, and glass surface is prone to the waveform lines because of the inequality of being heated, and reflecting condensation is caused great influence, and in addition, consistency of product is relatively poor; (2) mechanical cold deformation: level crossing issues biological reason distortion in the effect of extraneous power, obtains required form and mechanical fixation.This technology cost is low, operates simply relatively, and minute surface is comparatively smooth, defectives such as no lines, and spotlight effect is better, can bend to different radians as required.
Machinery cold deformation effect aspect the manufacturing moulding of globoidal mirror is better, and desirable mirror supporting surface is continuous globoidal structure, will cause the mirror supporting construction heavier like this, and to surperficial the having relatively high expectations of cambered surface, manufacturing cost is bigger.Patent of invention " a kind of manufacturing approach (CN 101661125A) that is used for the curved reflector of solar energy heliostat " has proposed the method that sun power curved surface heliostat is made in a kind of mechanical cold deformation; Its mirror holder is a gap structure; It is complicated that yet the unitary construction of curved mirror shows slightly, and process needs under middle gentle low pressure condition, to carry out.
Summary of the invention
To the deficiency of above-mentioned prior art, the object of the present invention is to provide a kind of sun power cambered surface catoptron mechanical bend forming method, this method is simple and practical, and under normal temperature and pressure conditions, can make moulding.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of sun power cambered surface catoptron mechanical bend forming method; Level crossing is placed on the supporting surface of mirror holder; Evenly be coated with the bond medium that is the emulsifiable paste shape under the thick normal temperature of 2～5mm on the supporting surface; Mirror holder supporting surface is discontinuous plan cambered surface, said plan arc shape with the shape of the cambered surface catoptron that will make consistent.Adopt extraneous mechanical force bringing device that level crossing and supporting surface are close to together.
Described mirror holder supporting surface is the plan globoidal structure that is combined by many discrete strip supporting surfaces; Said strip supporting surface just in time is arranged on the arc shape curve of catoptron of required manufacturing; And be symmetrically arranged, and the quantity of discrete strip supporting surface is three at least.
Described bond medium be the emulsifiable paste shape under the normal temperature can adhering glass and the glue of metal, can adopt silicone structure sealant or organosilicon sealant.
Described extraneous mechanical force bringing device is a kind of device that vertical external force can be provided, and comprises weight or hydraulic means etc.
Mirror holder supporting surface is combined by many discrete list structures, and is not only in light weight, and avoided the high-precision processing requirement of continuous globoidal structure, and cost is low.
Adopt method of the present invention to make the cambered surface catoptron, simple, cost is low, precision can satisfy the optically focused demand, but large-scale promotion use, be applied to association areas such as Salar light-gathering heat generating.
Description of drawings
Synoptic diagram when accompanying drawing is to use the present invention to make globoidal mirror.
Specific embodiments
Below in conjunction with accompanying drawing the present invention is done and to be described in detail.
With reference to accompanying drawing, a kind of sun power cambered surface catoptron mechanical bend forming method is with a block length 3m, wide 1m; Thick 3.2mm level crossing 1 places whole long 3m, and on the supporting surface of wide 1m mirror holder 3, supporting surface is made up of 5 discrete support bars, is symmetrically arranged; The length of support bar is 3m, and the support bar upper face evenly is coated with the bond medium 2 that is the emulsifiable paste shape under the thick normal temperature of 2～5mm, the plan arc shape of mirror holder supporting surface with the shape of the cambered surface catoptron that will make consistent, above level crossing lies in; Use extraneous mechanical force bringing device 4 to make level crossing crooked, the supporting surface of level crossing 1, bond medium 2 and mirror holder 3 is close together, after 15 minutes; Bond medium begins to solidify, after 1 hour, and the bond medium initial solidification; The first product globoidal mirror, full solidification after 24 hours just is a finished product.
Wherein in the accompanying drawing, 1, level crossing; 2, bond medium; 3 mirror holders; 4 extraneous mechanical force bringing devices
