Abstract
The present invention discloses a solar energy reflector. The solar energy reflector comprises a wavy composite reflecting surface, wherein a lot of reflecting surfaces are arranged on a rotating shaft to form the wavy composite reflecting surface. The solar energy reflector is characterized in that, at least the peaks on partial wavy composite reflecting surface are not positioned at the same planes as the other peaks positioned on the other wavy composite reflecting surface. According to the present invention, edges of each reflecting surface on the solar energy reflector are positioned on different planes, such that the angle of the reflecting surface is easy to be adjusted; the light reflected by the reflecting surface forms a small incident angle on a solar energy conversion receiver, and can not be blocked by the adjacent reflecting surface, and the incident energy has high density due to the small incident angle; the rotating shaft is arranged on an end of the solar energy reflector, such that the solar energy reflector firstly rotates in a vertical range and a horizontal range so as to rotate and fix the solar energy reflector close to the ground when the wind is large, and the solar energy reflector is easy to be cleaned after rotating the solar energy reflector close to the ground; the assistant solar energy conversion receiver is added to the solar energy reflector, such that the energy can be absorbed well.
Description
Technical field
The present invention relates to the reflector in the solar energy conversion system, especially a kind of reflector that constitutes by a plurality of reflectings surface.
Background technology
Solar energy has obtained people's attention as clean energy resource, and existing conversion of solar energy system exists the problem of the higher and transformation efficiency of cost.
Existing a kind of conversion of solar energy system such as WO03/052330A1 describe, its reflector is the solar reflector that constitutes with a plurality of plane reflection faces, wherein each reflecting surface formation section configuration is the composite plane reflecting surface of W shape, shine the sunlight on reflector, be reflected to the conversion of solar energy receiver that places reflecting surface both sides aggregation zone, whirligig and solar tracking device also be housed in the reflector bottom.It is lower that this invention expectation obtains a kind of cost, and transformation efficiency higher solar energy conversion system.
Summary of the invention
The purpose of this invention is to provide a kind of solar reflector, this reflector can make the sunshine of incident form less incident angle through the reflection back on receiver.
Technical scheme of the present invention is as follows:
A kind of solar reflector comprises the wavy compound reflecting surface that a plurality of reflectings surface that are installed on the rotating shaft constitute, and it is characterized in that, has crest on the wavy compound reflecting surface of part and other crests at least on Different Plane.
Supplementary technology scheme of the present invention is as follows:
Preferably, have at least the crest on the wavy compound reflecting surface of part to be on the curve, these curve two ends are low, and there are two peak values the centre.
Preferably, described reflecting surface is the photovoltaic reflecting surface.
Preferably, described reflecting surface is the heat energy reflecting surface.
Preferably, described rotating shaft is installed in an end of reflector.
Preferably, the conversion of solar energy receiver is separately fixed at the two ends of reflector by support, and is positioned at the focal area of reflecting surface.
Preferably, the conversion of solar energy receiver is separately fixed at the two ends and the stage casing of reflector by support, and is positioned at the focal area of reflecting surface.
Preferably, described reflecting surface is a curved surface.
Preferably, described reflecting surface is the plane.
The invention has the beneficial effects as follows: the edge of each reflecting surface is in the Different Plane on the reflector, help adjusting the angle of reflecting surface, make the incidence angle of light on the conversion of solar energy receiver of reflecting surface reflection littler, and can not covered by contiguous reflecting surface, less incidence angle can make projectile energy have higher density; Rotating shaft is arranged on an end of reflector, helps reflector and rotate earlier, be convenient to reflector to be rotated ground proximity and fix, and after rotating to ground proximity, also be convenient to clean reflecting surface in the bigger time of wind-force in vertical and horizontal extent; Increase auxiliary conversion of solar energy receiver in the reflector stage casing and can be used for better absorbing energy.
Description of drawings
The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of solar reflector embodiment of the present invention.
Fig. 2 is the cutaway view of solar reflector reflecting surface shown in Figure 1.
Fig. 3 is the full curve figure at reflecting surface wave crest point shown in Figure 2 place.

The specific embodiment
Specific embodiments of the invention, as shown in Figure 1, the reflector in a kind of solar-energy conversion systems comprises a pedestal, is used to install reflecting surface, the compound reflecting surface 1 on the solar radiation reflector is made of the plane reflection face that combines in a large number.Each plane reflection face combines along the limit with another face, has formed wavy compound reflecting surface as shown in Figure 1.Reflecting surface can be made by plastics or all suitable materials such as metal or glass, and reflecting surface can be photovoltaic reflecting surface or heat energy reflecting surface.Single reflecting surface can be that curved surface also can be the plane.Reflecting surface preferably has different angles of inclination, and when shining upon equidirectional, the solar radiation meeting is injected reflecting surface with different angles.The crest of compound reflecting surface 1 is on the curve, and these curve two ends are low, and there are two peak values the centre, and as shown in Figure 2, this curve as shown in Figure 3.Being provided with like this can make the incidence angle of light on the conversion of solar energy receiver of reflecting surface reflection littler, and can not covered by contiguous reflecting surface, and less incidence angle can make projectile energy have higher density.The curve at place, subwave peak only is to understand the example of enumerating for the ease of helping in the compound reflecting surface in the present embodiment, and this curve can be the full curve with one or more peak values in actual applications.
Conversion of solar energy receiver 3 is separately fixed at the two ends of reflector by support, and is positioned at the focal area of reflecting surface, and when promptly solar radiation shone reflecting surface, solar radiation can focus on the conversion of solar energy receiver, as shown in Figure 4.
During for the ease of or cleaning big reflector is rotated ground proximity and fix, the rotating shaft 3 of reflector can be arranged on an end of reflector at wind-force.Reflector can rotate in level and vertical range around rotating shaft 2 like this.
In order to increase the absorption efficiency of solar energy, can increase an auxiliary conversion of solar energy receiver 3 in the stage casing of reflector, this auxiliary conversion of solar energy receiver 3 is fixed on the reflector stage casing by support.
