[technical field]
The utility model relates to a kind of photovoltaic power generation equipment, particularly a kind of photovoltaic power generation equipment with light reflecting device.
[background technology]
Photovoltaic generation is the focus in new energy technology research field now, the photo-voltaic power generation station of large wattage has been set up in the place of many illumination abundances one after another, more electric power is changed out in irradiation by a large amount of sunlights, yet, in current technology, the light conversion efficiency of photovoltaic generation only maintains 12%～18% left and right, but the photovoltaic generation cost of unit are is very high, makes photovoltaic generation lose the economic competition advantage with conventional energy resource because of Cost Problems; Therefore, have and need the manufacturer of many photovoltaic panels to drop into a large amount of research and development, want by the raw material of photovoltaic panel or the light conversion efficiency of manufacturing process raising photovoltaic panel, but in application, still cannot break through the threshold of 20% light conversion efficiency so far.
In addition, because the position of sun every day is all different, special in seasonal variations, the angle of solar light irradiation can produce skew, makes the irradiation that the photovoltaic power generation equipment that originally sets cannot complete reception sunlight and reduces the efficiency of generating.
Therefore the light utilization efficiency that, how effectively to improve photovoltaic power generation equipment has become industry urgent problem.
[utility model content]
For addressing the above problem, therefore the utility model provides a kind of light reflecting device of photovoltaic power generation equipment, photovoltaic power generation equipment includes light receiving plate, light reflecting device comprises base, is arranged at the support on base, and is installed on the reflecting plate on support, reflecting plate has the plane of reflection, the plane of reflection, towards light receiving plate, has spacing between reflecting plate and light receiving plate, and reflecting plate and horizontal plane angle are between 10 degree～80 degree.
Further, aforementioned brackets is single-side stand, branched or forked type support.
Further, aforementioned intervals is between 10cm～50cm.
Further, the length of aforementioned reflecting plate is not more than the length of light receiving plate.
Further, the upper end of aforementioned light receiving plate has the top plane of reflection, and the angle of the top plane of reflection and light receiving plate is between 90 degree to 180 degree.
Further, aforementioned reflecting plate material is mirror face stainless steel.
Therefore, main purpose of the present utility model is to provide a kind of light reflecting device of photovoltaic power generation equipment, by baffle reflection light, to light receiving plate, makes light receiving plate receive more light and improves light utilization efficiency.
Moreover an object more of the present utility model is to provide a kind of light reflecting device of photovoltaic power generation equipment, because reflecting plate is articulated on support, therefore can adjust the angle between reflecting plate and light receiving plate according to angle of incidence of light degree, increase by this reflection light quantity.
In addition, another beneficial effect of the utility model is, because the light receiving plate of photovoltaic power generation apparatus is towards light reflecting device, in large-scale photovoltaic power generation equipment environment, light reflecting device is equivalent to be arranged between two photovoltaic power generation equipments, form triangular structure with photovoltaic power generation equipment, can effectively improve the ability of Wind-Pressure Resistance, increase stability and the durability of photovoltaic power generation equipment.

[embodiment]
Because the utility model mainly discloses a kind of light reflecting device of photovoltaic power generation equipment, wherein related photovoltaic generation principle, knows that for correlative technology field has the knowledgeable can understand, conventionally therefore hereinafter to illustrate, no longer do complete description.Meanwhile, graphic with what hereinafter contrasted, only express the structural representation relevant with the utility model feature, also do not need according to the complete drafting of actual size, formerly explanation.
Please refer to Fig. 1, is an embodiment of the present utility model.The light reflecting device of the photovoltaic power generation equipment the utility model proposes, wherein, photovoltaic power generation equipment 100 includes light receiving plate 10, light reflecting device 20 comprises base 21, support 22 and reflecting plate 23, support 22 is arranged on base 21, reflecting plate 23 is arranged on support 22, in the present embodiment, support 22 is branched 221, reflecting plate 23 has the plane of reflection 231, the plane of reflection 231 is towards light receiving plate 10, the material of reflecting plate 23 can be mirror face stainless steel, plating aluminium oxide film, glass-mirror etc., or the reflection plated film that can form in other materials all can, but main high temperature resistance and the wear-resisting reflection material selected in actual implementation process, at this not with above-mentioned several being limited, as long as can reach the effect of reflection ray.By this, reflecting plate 23 can be by light reflection to light receiving plate 10, in addition, between reflecting plate 23 and light receiving plate 10, there is spacing d, spacing d is between 10cm～150cm, meaning is that reflecting plate 23 is not connected with light receiving plate 10, between light reflecting board 23 and horizontal plane h, has angle theta 1, and angle theta 1 is between 10 degree～80 degree.
In addition, the maximum length L 2 of reflecting plate 23 is not more than the length L 1 of light receiving plate 10, so can avoid invalid reflection ray, causes the waste of manufacturing on reflecting plate 23 costs.
Please refer to Fig. 2, further, in order there to be better light utilization ratio, upper end at light receiving plate 10 can install the top plane of reflection 11 additional, the angle theta 2 of the top plane of reflection 11 and light receiving plate 10 is between 90 degree～180 degree, can further recycle the reflection ray of many Yus by this, improve the light quantities received of light receiving plate 10.
Refer again to Fig. 3, support 22 described in the utility model can be single-side stand 222 or branched 221 as shown in Figure 1.
Refer again to Fig. 4, support 22 described in the utility model can also be forked type support 223, and reflecting plate 23 is arranged in the branch 2231 of forked type support 223, and between reflecting plate 23Yu branch 2231, pin-jointed structure 224 can be set.
Refer again to Fig. 5, in large-scale photovoltaic power generation equipment 100 environment, the position that light reflecting device 20 of the present utility model arranges is positioned at the back side of another photovoltaic power generation equipment 100 just, and form a leg-of-mutton structure, can improve by this ability of photovoltaic power generation equipment 100 opposing blast, reduce the impact that wind-force causes photovoltaic power generation equipment 100, increase stability and the durability of photovoltaic power generation equipment 100.
