Embodiment Construction

[0025] Such as figure 1 As shown, the high-reflection strengthened composite glass mirror 100 is a composite structure, and its composite layer structure is as follows: it is sequentially composed of high-transmittance flat strengthened glass 1 (generally, thinner and large-area glass is used), a silver-plated reflective layer 2, Protective layer 3 (which can be metal coatings such as copper and nickel, or resin and fluorocarbon paint), interlayer 4 (PVB, EVA interlayer protective layer), and back plate layer 5. The back plate layer 5 can be made of glass fiber reinforced plastics Board FRP; also PET, TPE, TPT and other back film, tempered glass, etc.

[0026] In addition, a pulling device is fixed (adhesively may be used) on the back plate layer 5 . see figure 2 , 3 , 4. The pulling device includes: a connecting square tube 6 bonded to the surface of the protective backboard layer 5, a pulling screw 7 installed on the connecting square tube 6 and an adjusting nut 12 coope...

Abstract

The invention relates to the technical field of solar energy applying products, in particular to a one-dimensional light-condensing drawing-formed groove-type parabolic mirror and a manufacturing method thereof. The parabolic mirror comprises a high-reflection tempered composite glass mirror, wherein the glass mirror is arranged on a bracket; the bearing surface, which is used for bearing the glass mirror, of the bracket is arc-shaped; a drawing device is fixed on the glass mirror and connected with a connecting part on the bracket; and the glass mirror is elastically deformed and tightly attached to the arc-shaped bearing surface of the bracket under the action of drawing force produced between the drawing device and the connecting part. Downward pulling force is applied to the glass mirror through drawing force produced by a drawing screw rod and an adjusting nut, so that the glass mirror is deformed, the radian of the glass mirror is changed and the glass mirror is finally tightly attached to the support cambered surface of the bracket. Therefore, the radian of the glass mirror is determined and good light condensing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of solar energy application products, in particular to a one-dimensional concentrating drawing forming trough parabolic mirror and a manufacturing method thereof. Background technique [0002] Solar energy has many advantages such as cleanliness and environmental protection, and more and more people pay attention to it. For example, one-dimensional concentrated solar energy products usually use parabolic mirrors to concentrate sunlight into a light band, and then convert the concentrated light into other energy. Concentrating solar energy products can increase the energy density of solar energy. Using concentrated photovoltaics can reduce the use of expensive solar cells. They can also be used for solar heat collection, which can then be used to generate electricity for heating or cooling. However, the current production of concentrating mirrors generally adopts the process of high-temperature baking or ben...
