The trough type solar heat-collector having in prior art, its catoptron adopts ultra-thin glass catoptron to be attached to the method manufacture of the substrate that fiberglass makes, the moulding process cost of fiberglass substrate is higher and weatherability is bad, easily distortion, causes subsides glass mirror to be thereon difficult to form parabolic shape after distortion.
The catoptron of some groove type heat collectors adopts ultra-thin glass catoptron to be attached to the method manufacture on glass of hot bending.Because accuracy requirement is high, the process costs of its glass bending moulding is higher.And when catoptron is installed, catoptron is fixing by 4, back, the man-hour of adjusting these relative position of 4 needs during installation is more, has increased installation cost.
The employing membraneous material also having is as reflecting material, and invents the face type that a kind of tensioning system keeps reflectance coating.In this invention, endothermic tube and heat collector link together and around the rotating shaft at reflectance coating place, rotate simultaneously.This tensioning system reliability is not high, is difficult to meet the reliability of catoptron parabolic shape.The tracking means of this patent is realized by power wheel in addition, and reliability and weatherability are not high.
Summary of the invention
The object of the invention is to, catoptron moulding process of a kind of trough type solar heat-collector and products thereof is provided, it has advantages of, and moulding process is simple, processing cost is low, not yielding, convenient disassembly and weather resisteant good.
Technical scheme of the present invention: a kind of catoptron moulding process of trough type solar heat-collector, comprises the following steps:
Step 1: casting mirror support, adopt aluminium alloy or steel cast-in-block mode to cast out top with the mirror support of draw-in groove, the upper and lower surface in draw-in groove is parabolic cylinder;
Step 2: cutting ultra-thin mirror and corrugated plate, according to preliminary dimension cutting ultra-thin mirror and corrugated plate, be then bonded in ultra-thin mirror on the end face of corrugated plate;
Step 3: installation forming, bonding ultra-thin mirror and corrugated plate are inserted in the draw-in groove of mirror support, corrugated plate is final forms the parabolic cylinder identical with draw-in groove upper and lower surface, and due to the elasticity of ultra-thin mirror, catoptron is also by bending and form parabolic cylinder.
In the catoptron moulding process of aforesaid trough type solar heat-collector, the back coating face of ultra-thin mirror is bonded in the end face of corrugated plate by mightiness belt.
In the catoptron moulding process of aforesaid trough type solar heat-collector, described corrugated plate adopts aluminium, steel or alloy material to be made.
A kind of catoptron that adopts the trough type solar heat-collector that aforesaid moulding process processes, comprise mirror support, ultra-thin mirror, corrugated plate, mightiness belt and draw-in groove, 2 identical mirror supports of shape size are set up in parallel, the top of 2 mirror supports is equipped with draw-in groove, upper and lower surface in draw-in groove is parabolic cylinder, in draw-in groove, be provided with ultra-thin mirror and corrugated plate, the bottom surface of ultra-thin mirror and the end face of corrugated plate bond together.Because ultra-thin mirror itself is very thin, intensity and toughness is all resisted wind load not, so corrugated plate will support and protect catoptron after will the substrate as catoptron itself forming parabolic cylinder, the special construction of corrugated plate itself makes it can bending.
In the catoptron of aforesaid trough type solar heat-collector, mirror support is provided with triangle through hole.Triangle through hole is set on mirror support and can reduces manufacturing cost.
In the catoptron of aforesaid trough type solar heat-collector, mirror support adopts aluminium alloy or steel making to form.Mirror support adopts aluminium alloy or steel making to form, and can make it have corrosion-resistant, on-deformable advantage.
In the catoptron of aforesaid trough type solar heat-collector, the width on corrugated plate between adjacent two ripples is 15mm～45mm.
In the catoptron of aforesaid trough type solar heat-collector, the width on corrugated plate between adjacent two ripples is preferably 25mm.
In the catoptron of aforesaid trough type solar heat-collector, the ripple cross sectional shape of corrugated plate is square, trapezoidal or triangle.
Compared with prior art, the present invention is by being pasted together ultra-thin mirror and corrugated plate, then by the draw-in groove on mirror support, make it form parabolic cylinder, this technique is not only simple, and can greatly reduce manufacturing cost, and there is good weatherability, can effectively prevent that the long-term situation about deforming of using from occurring.
Mode due to employing draw-in groove fixes ultra-thin mirror and corrugated plate in addition, so dismounting is all very convenient, can reduce staff's workload.
