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.
