In recent years, realized the Salar light-gathering reception abroad in the photovoltaic matrix of some solar power stations, domestic also have similar experimental rig, promotes obtaining on the solar domestic product but these apparatus structure complexity, bulky, cost are high-leveled and difficult.
Summary of the invention:
In order to overcome shortcomings such as existing beam condensing unit complicated in mechanical structure, bulky, cost height. the present invention is directed to the deficiency that prior art exists, prior art is improved, proposed the Salar light-gathering receiving system that a kind of volume is little, simple and reliable for structure, cost is low, the optically focused reception that it can realize solar energy.
The technical solution adopted for the present invention to solve the technical problems is: a plurality of Salar light-gathering receiving mechanisms have been installed in a rectangular box, on rectangular box, be stamped a planar transparent cover plate, the planar transparent cover plate is enclosed in each Salar light-gathering receiving mechanism in the rectangular box, each Salar light-gathering receiving mechanism proper alignment is in rectangular box, each Salar light-gathering receiving mechanism all is made of a paraboloid of revolution reflective mirror and a luminous energy receiver, and the opening of the paraboloid of revolution reflective mirror of each Salar light-gathering receiving mechanism is over against the planar transparent cover plate.
The luminous energy receiver of each Salar light-gathering receiving mechanism is by a hemisphere face solar panel, a taper seat reflective mirror and a hemisphere face transparent light guide lid constitute, the top of taper seat reflective mirror has a light incident circular hole, the focus of the centre of sphere of the hemisphere face solar panel of each Salar light-gathering receiving mechanism luminous energy receiver and the paraboloid of revolution reflective mirror of this Salar light-gathering receiving mechanism overlap and the opening of this hemisphere face solar panel over against the reflecting surface of this paraboloid of revolution reflective mirror, the focus that the taper seat reflective mirror of the luminous energy receiver of each Salar light-gathering receiving mechanism covers closely at the paraboloid of revolution reflective mirror of the center of circle of the light incident circular hole of the opening part of the hemisphere face solar panel of this luminous energy receiver and this taper seat reflective mirror and this Salar light-gathering receiving mechanism overlaps, the hemisphere face transparent light guide of the luminous energy receiver of each Salar light-gathering receiving mechanism is covered on the light incident circular hole of the taper seat reflective mirror of this luminous energy receiver and the focus of the paraboloid of revolution reflective mirror of the centre of sphere of this hemisphere face transparent light guide lid and this Salar light-gathering receiving mechanism overlaps, the hemisphere face transparent light guide lid of each luminous energy receiver, hemisphere face solar panel and taper seat reflective mirror constitute a closed cavities
When sunlight during perpendicular to the incident of planar transparent cover plate, reflection by each paraboloid of revolution reflective mirror makes reflection ray pass the light incident circular hole vertical irradiation of each luminous energy receiver taper seat reflective mirror on the hemisphere face solar panel of each luminous energy receiver, the luminous energy that is radiated on the hemisphere face solar panel is converted to electric energy by the hemisphere face solar panel, the reflection ray of each luminous energy receiver hemisphere face solar panel is through the reflection of the taper seat reflective mirror of each luminous energy receiver, be radiated at once more on this hemisphere face solar panel, further improved the photoelectric conversion rate of each luminous energy receiver, hemisphere face transparent light guide lid because of each luminous energy receiver, hemisphere face solar panel and taper seat reflective mirror constitute a closed cavities, and the light incident circular hole of each taper seat reflective mirror is very little, the luminous energy major part in closed cavities that enters light incident circular hole changes electric energy into, has therefore significantly improved the photoelectric conversion rate of each luminous energy receiver.
The invention has the beneficial effects as follows: the reflective focussing force by each paraboloid of revolution reflective mirror has significantly improved the sun light intensity that is radiated on each luminous energy receiver, thereby significantly improved the photoelectric conversion rate of each luminous energy receiver, realized that higher photoelectric conversion rate is all arranged under the environment of the high light and the low light level.
