Background technology:
Solar energy is a kind of clean energy resource, inexhaustible, nexhaustible, can not cause environmental pollution yet, nowadays, no matter in coastal cities, still in inland city, solar product enters people's the visual field just more and more, solar street light, solar lawn lamp, solar energy garden lamp, solar corridor lamp, bus station's desk lamp, traffic lights or the like, various solar water heaters have also been walked close to huge numbers of families.But these solar product great majority all do not have light-focusing function, cause solar energy utilization ratio low.The light intensity on solar energy receiving element surface doubles, the receiving efficiency of solar energy receiving element will double, the focus of solar energy industry technology competition at present mainly is the battle of solar energy receiving efficiency, as seen improve receiving efficiency to whole industry significance level, therefore can effectively improve the intensity of illumination of solar energy receiving element, just become the problem of paying close attention to the most when people utilize solar energy.
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, the opening of the paraboloid of revolution reflective mirror of each Salar light-gathering receiving mechanism is over against the planar transparent cover plate, and the luminous energy receiver of each Salar light-gathering receiving mechanism is installed on the focus of paraboloid of revolution reflective mirror of this Salar light-gathering receiving mechanism.
The luminous energy receiver of each Salar light-gathering receiving mechanism is made of a sphere solar panel and a hemisphere face transparent light guide lid, have a light incident circular hole on the sphere solar panel, the light incident circular hole of the sphere solar panel of each Salar light-gathering receiving mechanism luminous energy receiver is over against the reflective surface of the paraboloid of revolution reflective mirror of this Salar light-gathering receiving mechanism, the centre of sphere that the hemisphere face transparent light guide of each Salar light-gathering receiving mechanism luminous energy receiver is covered on the light incident circular hole of the sphere solar panel of this Salar light-gathering receiving mechanism luminous energy receiver and this hemisphere face transparent light guide is covered and the center of circle of this light incident circular hole overlap, the focus of the center of circle of the light incident circular hole of the sphere 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 overlaps, the centre of sphere of the sphere solar panel of each Salar light-gathering receiving mechanism luminous energy receiver is positioned on the symmetry axis of paraboloid of revolution reflective mirror of this Salar light-gathering receiving mechanism, the hemisphere face transparent light guide lid and the sphere solar panel of each luminous energy receiver constitute a closed cavities
When sunlight during perpendicular to the incident of planar transparent cover plate, the light incident circular hole that reflection by each paraboloid of revolution reflective mirror makes reflection ray pass each luminous energy receiver spherical hollow heat conduction cavity is radiated on the sphere solar panel of each luminous energy receiver, the luminous energy that is radiated on the sphere solar panel is converted to electric energy by the sphere solar panel, hemisphere face transparent light guide lid and closed cavities of sphere solar panel formation because of each luminous energy receiver, and the light incident circular hole of sphere solar panel 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.
