Abstract
The invention discloses a solar energy gathering unit and a reflector used by the unit. The two sides of the medial axis of a basal plate of the reflector are respectively provided with at least two reflection bar-typed surfaces, each of which slightly inclines to the direction of the medial axis, and the farther the bar-typed surfaces are away from the medial axis, the bigger the inclination angles are. The invention has simple processing technique and low manufacture cost.
Description
Technical field
The present invention relates to field of solar energy, be specifically related to a kind of solar collecting device and this device is reflection board used.
Background technology
Because sun power has cleaning, advantage such as renewable, each state all competitively develops its new and high technology.China is that the big country of energy output also is the big country of energy resource consumption, makes good use of sun power and has strategic importance for China; And present solar thermal collector both domestic and external is of a great variety, but mostly structure is numerous and diverse, the ratio of performance to price is low, as for reflector, its effect be will reflection light focusing to heat collector.Heat collector can be an electrothermal transducer according to the purpose difference of using, but the reflection board used complex structure of existing solar collecting device, if any reflector be parabolic type.
There is following defective in the parabolic type reflector:
1, sunshine is gathered in a bit by Parabolic reflector is reflective afterwards, if reflector curvature and standard curvature everywhere is inconsistent, then sunshine can't come together in a bit after reflection accurately.Large-scale parabolic machining precision is difficult to guarantee, the die sinking complex process.Because the reflector substrate is curved surface, when attaching reflective membrane on reflector, reflective membrane can't attach easily again;
2, since sunshine after the reflection of Parabolic reflector, its Reflect light line gathers in a bit, when heat collector was set, this heat collector can only be arranged on this reflective spot, the space is little, is provided with also inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of solar collecting device and this device reflection board used, the processing and the setting of more convenient reflector of the present invention and heat collector have also reduced manufacturing cost.
The present invention is achieved through the following technical solutions:
A kind of solar collecting device, comprise reflector, be respectively equipped with at least two reflective bar shaped faces in the both sides of the axis of reflector substrate, each reflective bar shaped face all slightly tilts to the axis direction, and reflective bar shaped identity distance is far away more from the axis, and the angle of its inclination is big more.
The preferred structure of reflective bar shaped face is:
By described axis and perpendicular to the face of described reflector substrate is middle axial plane, the vertical line of described reflective bar shaped face and middle axial plane intersect and form intersecting lens, and the distance of described axis and this intersecting lens is that L1, described axis are that L2, this reflective bar shaped face are with respect to the angle that described reflector substrate tilts with the distance of this reflective bar shaped face; , tg (2﹠amp then; )=L2/L1.
The machine-shaping of described reflector substrate one is posted reflective membrane at described reflector upper surface of base plate.
Described reflector is at least two, and each reflector splices along described axis direction.
On described intersecting lens, be provided with microscler heat collector.
The described reflective bar shaped face of each of both sides, described axis is with respect to described axis symmetry.
Among the present invention, the reflective surface of reflector is made up of a plurality of reflective bar shaped faces, in use, the sun location tracking device is followed the tracks of the sun, sunshine is injected on each reflective bar shaped face perpendicular to the reflector substrate, on the intersecting lens of axial plane, make sunshine accumulate straight line on this intersecting lens during each reflective microscler face reflexes to the sunshine of injecting respectively, the application's structure has following advantage:
1, convenient processing and manufacture, technology is simple, and the reflector substrate can be by injection moulding or alternate manner one processing and manufacturing moulding, with respect to original reflector, as the parabolic type reflector, its processing technology is very simple, and when adopting single injection-molded, also can guarantee the machining precision of reflector;
When 2, attaching reflective membrane on the reflector substrate, because reflective bar shaped face is the plane, in the attaching process, can only adopt one whole reflective membrane to finish, and reflective membrane is smooth, fold is few;
3, sunshine is after the reflector reflection, and its light comes together in a wire zone, and for original dotted region, the layout of more convenient heat collector has further reduced manufacturing cost.

Embodiment
As shown in Figure 1 to Figure 3, a kind of solar collecting device, comprise reflector, both sides in the axis 4 of reflector substrate 7 are respectively equipped with at least two reflective bar shaped faces 3, each reflective bar shaped face 3 all slightly tilts to axis 4 directions, and reflective bar shaped face 3 is far away more apart from axis 4, and the angle of its inclination is big more.
Particularly, the reflective bar shaped face 3 of each of 4 both sides, axis is with respect to axis 4 symmetries, by axis 4 and perpendicular to the face of reflector substrate 7 is middle axial plane 5, the vertical line of reflective bar shaped face 3 and middle axial plane 5 intersect and form intersecting lens 6, and axis 4 is that L1, axis 4 are that L2, this reflective bar shaped face 3 are with respect to the angle that reflector substrate 7 tilts with the distance of this reflective bar shaped face 3 with the distance of this intersecting lens 6; , tg (2﹠amp then; )=L2/L1; Each reflector substrate posts reflective membrane by the machine-shaping of injection molding way one at the reflector upper surface of base plate, and aforementioned reflector is four, and each reflector is the splicing of 4 directions along the axis, is provided with the heat collector 2 of long tubular on intersecting lens 6.
In use, by sun location tracking device etc. the angle of sunshine is followed the tracks of, sunshine is injected on each reflective bar shaped face 3 perpendicular to reflector substrate 7, each reflective microscler 3 respectively the sunshine of injecting is reflexed on the intersecting lens 6 of axial plane 5, make sunshine accumulate straight line on this intersecting lens 6, the structure of present embodiment has following advantage:
