Abstract
The utility model relates to a compound parabolic spotlight reflector, include the glass vestlet and encapsulate at the inside heat receiver of glass vestlet that this glass vestlet is installed in the inboard of speculum, the speculum is two, and along the setting of heat receiver bilateral symmetry, each speculum is equallyd divide for the dull and stereotyped reflecting region on upper portion and the curved surface reflecting region of lower part, dull and stereotyped reflecting region include the dull and stereotyped speculum of bracket and several, each dull and stereotyped speculum is installed on the bracket through a calorie firmware, the overlap joint is together in proper order for adjacent two dull and stereotyped speculums. The utility model has the advantages that: because the relative lower part curved surface reflecting region of curvature radius of the compound dull and stereotyped reflecting region in parabolic upper portion greatly much, optics efficiency can not reduce 5%, and close half the but the cost can reduce, the gap that the lap -joint left more is favorable to row rainwater and dust, and the plane of reflection more can keep clean, keeps high reflectivity, and dull and stereotyped speculum more is favorable to the packing transportation simultaneously.
Description
Technical field
The utility model relates to a kind of composite parabolic investigation on several focus reflectors, especially a kind of installation for convenience detach, is convenient to the composite parabolic investigation on several focus reflectors transported.
Background technology
Composite parabolic (CPC) mirror technology warm field that utilizes in solar energy of non-tracking optically focused has started to be paid attention to and develop, composite parabolic reflecting curved surface design for various absorber shape is also gradually improved, see accompanying drawing 1, vacuum pipe heat-collecting pipe 1, composite parabolic speculum 2, prior art mainly contains heat-bending glass speculum and the shaping two kinds of technical schemes of aluminium sheet metallic-membrane plating reflector cold rolling, be integral manufacturing shaping, the cost of two schemes is all very high, aluminium sheet metallic-membrane plating reflector cold rolling forming technique is difficult to the larger requirement of applicable CPC daylighting A/F, such as more than 200mm, one is shaping difficulty, two is that wind loading rating is poor, therefore, be necessary to invent applicable big uncork CPC condenser mirror, and cost is lower.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of composite parabolic investigation on several focus reflectors, the technical solution of the utility model is: a kind of composite parabolic investigation on several focus reflectors, comprise glass enclosure tube and be encapsulated in the absorber of glass enclosure tube inside, this glass enclosure tube is arranged on the inner side of speculum, described speculum is two, be symmetrical set along absorber, each speculum is divided into the flat reflective district on top and the camber reflection district of bottom, described flat reflective district comprises bracket and several flat reflective mirror, each flat reflective mirror is arranged on bracket by holding firmware, adjacent two flat reflective mirrors overlap successively.
Described holding firmware comprises claw and installing plate integrated with claw, described installing plate is vertical with claw to be arranged, described installing plate is provided through the installing hole of bolt, the upper end of each described flat reflective mirror is inserted in the draw-in groove of a wherein claw, and lower end is spacing by the back of another claw be adjacent.
Described holding firmware comprises claw and installing plate integrated with claw, described installing plate is vertical with claw to be arranged, described installing plate is provided through the installing hole of bolt, and the top and bottom of nethermost flat reflective mirror are inserted in the draw-in groove of claw respectively.
The lap-joint of adjacent two flat reflective mirrors is provided with gap.
The camber reflection district of bottom is that the shaping or glass bending of aluminium base speculum cold rolling is shaped.
The A/F of described speculum is greater than 200mm.
Described flat reflective mirror is glass reflector, and the width of each flat glass mirror is equal.
Described flat reflective mirror is glass reflector, and the width of each flat glass mirror is unequal, more on the lower the flat glass mirror in portion, and width is narrower.
The surface approach composite parabolic Theoretical Design curved surface of described flat reflective mirror composition.
The utility model has the advantages that: because the radius of curvature opposing lower portions camber reflection district of composite parabolic upper flat plate echo area is much bigger, when going approximation theory to design curved surface with many flat glass mirror composition broken line curved surfaces that cost is low, optical efficiency reduces less than 5%, but cost can reduce close to half, the gap that lap-joint leaves more is conducive to row's rainwater and dust, reflecting surface more can keep clean, maintains high reflectance, and flat reflective mirror is more conducive to packed and transported simultaneously.
