Abstract
The utility model discloses a solar energy paraboloid light-focusing baffle-plate, wherein the baffle-plate is composed of two bilateral light-focusing plates of which cross sections are parabola-shaped, and two bilateral connecting plates are connected between two light-focusing baffle-plates, of which cross sections are involute-shaped of a circle, and the light-focusing baffle-plate and the connecting plate are formed by the compressing of a mirror-faced stainless steel plate. Thereby the utility resolves the problem of the sunlight scattering of the prior baffle-plate and focuses the sunlight on the paraboloid, and has the advantages of reasonable structure, convenient machining and high utilization efficiency and the like, which is the ideal substitute of the current solar baffle-plate.
Description
The utility model relates to a kind of reflecting plate, the light gathering baffle-board that particularly a kind of solar energy is used.
At present, employed solar energy reflection plate generally is divided into mirror reflective plate and embossing aluminium sheet diffuse reflector in the prior art.Mirror reflective plate processing, easy for installation, but its shortcoming is that the generation scattering is big, and solar energy utilization ratio is low.Though embossing aluminium sheet diffuse reflector increases than the solar energy utilization ratio of mirror reflective plate, equally also can produce scattering, solar energy utilization ratio still is not fully utilized.
For overcoming the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of rational in infrastructure, easy to process, solar energy parabolic concentrator reflecting plate that solar energy utilization ratio is higher.
For achieving the above object, a kind of solar energy parabolic concentrator reflecting plate of the present utility model, described reflecting plate is combined by symmetrical two light gathering baffle-boards, and the light gathering baffle-board cross section is parabolic shape.
Also be connected with two symmetrical connecting plates between two light gathering baffle-boards, the connecting plate cross section is the involute shape in garden.
Described light gathering baffle-board and connecting plate are formed by the compacting of mirror face stainless steel plate.
The utility model is because reflecting plate is combined by symmetrical two light gathering baffle-boards and two symmetrical connecting plates, and the light gathering baffle-board cross section is parabolic shape, and the connecting plate cross section is the involute shape in garden; Solve mirror reflective plate and diffuse reflector sunshine has been produced the problem of scattering, made the solar light focusing that shines on the parabola, had rational in infrastructure, easy to process, solar energy utilization ratio advantages of higher.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Shown in Figure 1, a kind of solar energy parabolic concentrator reflecting plate of the present utility model, described reflecting plate is connected respectively with two symmetrical connecting plates 2,4 by symmetrical two light gathering baffle-boards 1,5 and combines, promptly by light gathering baffle-board 1 be connected with connecting plate 2, light gathering baffle-board 5 is connected with connecting plate 4, and then combines; Light gathering baffle-board 1,5 cross sections are parabolic shape, and connecting plate 2,4 cross sections are the involute shape in garden.Light gathering baffle-board 1,5 and connecting plate 2,4 are formed by the compacting of mirror face stainless steel plate.
Its operation principle is as follows: be made up of jointly parabola AB, the DC of common focus F and involute BO, the CO of circle by two, be the ω shape after fusing; Article two, the angle between parabolical main shaft BD and CA is acceptance angle.By the reflect focalization principle as can be known, parabola can be the convergence of rays parallel with its main shaft focus on one point, parabola can the convergence of rays parallel with the parabola main shaft in alignment be focal line.The morning, the sun was raised to a certain height incident ray when parallel with CA, focused on the F point after the light reflection on the parabola CD; When the sun continues when mobile, light is also moved to the BD direction by CA gradually; The incidence angle of light on parabola CD increases gradually, and it is big that angle of reflection also becomes thereupon, so the focus after the reflection just moves down to the C point gradually along FC.And for parabola BA, situation is just the opposite, and the incidence angle of light on parabola BA diminishes gradually, and angle of reflection also diminishes thereupon, and the focus after the reflection is moved to the F point by B along BF; When incidence angle light was parallel with BD, the focus after the reflection focused on the F point.Hence one can see that, and reflection ray focuses between FB and the FC all the time.When design solar energy, need only vacuum heat collection pipe 3 is arranged on herein, vacuum heat collection pipe 3 is overlapped with focal line, just can fully absorb the energy of sunshine, thereby improve solar energy utilization rate greatly, improve the operating temperature of solar water heater, can produce the middle high-temperature solar water heater of different size model after the combination.Be the desirable substitute products of present solar energy reflection plate.
