Description

Technical Field

[0001] The invention relates to the technical field of trough type solar medium and high temperature heat utilization, and in particular to an aluminum plate reflector. Background Art

[0002] Trough solar collectors are widely used in medium-temperature fields such as industrial hot water, industrial drying, industrial steam, seawater desalination, central heating and cooling, and high-temperature fields such as thermal power generation.

[0003] With the help of the focusing effect of the parabolic reflector, the outlet temperature of the trough solar collector medium reaches 300℃ and a maximum of 550℃.

[0004] At present, the reflectors widely used in medium and high temperature projects are glass reflectors. The ultra-white glass substrate is made into parabolic glass through edge grinding, bending and tempering, and then plated with silver reflective layer, copper protective layer, paint anti-corrosion layer, etc., with a reflectivity of more than 92%.

[0005] Glass reflectors have major shortcomings in practical applications. First, the anti-collision effect of the mirror surface is poor, which is inconvenient. Second, the protection effect of the lower end of the mirror body is poor, which brings certain adverse effects to people's use process. For this reason, we propose an aluminum plate reflector. Summary of the invention

[0006] The main purpose of the present invention is to provide an aluminum plate reflector, which can effectively solve the problems in the background technology.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] An aluminum plate reflector comprises a stainless steel base plate, a fixing bolt hole is opened on the lower outer surface of the stainless steel base plate, mirror aluminum is arranged on the upper outer surface of the stainless steel base plate, a mirror anti-collision mechanism is arranged on the upper outer surface of the mirror aluminum, a mirror body protection mechanism is arranged on the lower middle part of the stainless steel base plate, the mirror anti-collision mechanism comprises an installation groove, a mirror fixing ring, a buffer pad and an installation adhesive pad, and the mirror body protection mechanism comprises a fixing gasket, a mirror body adsorption plate, a buffer base and a sealing ring.

[0009] Preferably, a mounting groove is provided on the outer surface of the lower end of the mirror fixing ring, a mounting adhesive pad is provided on the inner wall of the mounting groove, and a buffer pad is provided on the outer surface of the upper end of the mirror fixing ring.

[0010] Preferably, a buffer base is provided on the upper outer surface of the fixed gasket, a mirror body adsorption plate is provided on the upper outer surface of the buffer base, and a sealing ring is provided on the upper outer surface of the mirror body adsorption plate.

[0011] Preferably, the inner wall of the mounting groove is fixedly connected to the outer surface of one end of the mounting adhesive pad, the upper outer surface of the mirror fixing ring is fixedly connected to the lower outer surface of the buffer pad, and the other outer surface of the mounting adhesive pad is fixedly connected to the upper outer surface.

[0012] Preferably, the upper outer surface of the fixed gasket is fixedly connected to the lower outer surface of the buffer base, the upper outer surface of the buffer base is fixedly connected to the lower outer surface of the mirror body adsorption plate, the upper outer surface of the mirror body adsorption plate is fixedly connected to the lower outer surface of the sealing ring, and the upper outer surface of the sealing ring is detachably connected to the lower middle part of the stainless steel bottom plate.

[0013] Preferably, the stainless steel bottom plate is in a parabolic shape as a whole, a structural adhesive is provided between the mirror aluminum and the stainless steel bottom plate, and the lower end outer surface of the mirror aluminum is fixedly connected to the upper end outer surface of the stainless steel bottom plate by the structural adhesive.

[0014] Preferably, the upper and lower ends of the mirror aluminum are reserved with a length of mm and folded onto the stainless steel bottom plate, the surface of the mirror aluminum is plated with a SiO2 film layer, and the number of the fixing bolt holes is eight groups.

[0015] Preferably, the lower end outer surface of the stainless steel bottom plate is detachably connected to the upper end outer surface of the reflector bracket via fixing bolt holes and fixing bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the aluminum plate reflector can buffer the collision of the upper end of the reflector through the mirror anti-collision mechanism, prevent external force from damaging the aluminum plate reflector, and is beneficial to the protection of the aluminum plate reflector; the mirror body protection mechanism can buffer the collision of the lower end of the reflector with the mounting seat, prevent the mounting seat and the reflector from being too large and causing deformation of the reflector, and is beneficial to the installation of the aluminum plate reflector; the aluminum plate reflector uses mirror aluminum with relatively high reflectivity as a substrate to make the reflector, replacing the traditional glass substrate reflector, and has the following advantages compared with the traditional ultra-white glass reflector: high reflectivity, the reflectivity of traditional glass reflectors is generally around 92%, and the reflectivity of the aluminum plate reflector is as high as more than 96%; the SiO2 film layer is plated on the aluminum substrate, which can be used for a long time while maintaining the reflectivity attenuation of no more than 2%, and at the same time has a hydrophobic function and self-cleaning ability; high safety, the glass reflector is easy to transport, install, and use During use, the reflector is often broken due to external force. The aluminum plate reflector is a stainless steel and aluminum composite structure with high safety strength and will not break. The production process is simple and the energy consumption is low. The traditional glass reflector needs to be edged, bent, and tempered before the back is plated with a silver reflective layer, a copper protective layer, and a paint film anti-corrosion layer. A large amount of wastewater, dust, metal pollutants, etc. will be generated during the production process, and the energy consumption is high. The aluminum plate reflector only needs to customize the stainless steel plate and mirror aluminum plate according to the size of the reflector with different openings. The stainless steel plate is mechanically pressed into a parabolic shape, and the mirror aluminum is plated with a SiO2 film layer by a sol-gel method before it can be assembled. The total sol liquid in the SiO2 plating process can be reused, and the sintering temperature is 300℃±5℃, which is pollution-free and has low energy consumption. The cost is low. After calculation, the comprehensive cost of the aluminum plate reflector is about 25% lower per square meter than that of the traditional glass reflector. The entire aluminum plate reflector has a simple structure and is easy to operate, and the effect of use is better than that of the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS
