Description
Technical field
The present invention relates to technical field of solar, particularly relate to a kind of sun light tracking sensing device.
Background technology
As everyone knows, world energy sources is at full stretch, therefore the human development and utilization of always being devoted to new forms of energy such as sun power, and the development bottleneck in the technology of utilizing of sun power is the labyrinth of sun light tracking condenser system, wherein sun light tracking sensor is very crucial parts.At present, sun light tracking sensor comprises photosensitive device, sensor devices mostly, sensor devices receives sunshine, photosensitive device is according to the sunshine output tracking desired data that receives then, the defective that this structure exists is: sensor devices is subjected to the interference of other light sources in the surrounding environment easily, influence the degree of accuracy of sensor greatly, caused harmful effect.
Summary of the invention
The purpose of this invention is to provide a kind of sun light tracking sensing device, can effectively avoid the interference of other light sources in the surrounding environment.
For achieving the above object, technical scheme of the present invention is:
A kind of sun light tracking sensing device comprises base, and base is provided with four shadow shields that vertically arrange, and described every adjacent shadow shield is vertical mutually, it is characterized in that:
The outside, below of described every shadow shield is provided with for the optical fiber that receives sunshine,
The end of described each optical fiber is provided with the darkroom, and described optical fiber and darkroom all are arranged in the described base,
Be provided with soft light cover, photosensitive device and data output end in described each darkroom,
Described soft light cover is arranged between the end and photosensitive device of optical fiber,
Described photosensitive device and data output end are arranged at the bottom in darkroom.
Preferably, the height of every shadow shield of the present invention is 20-200mm; The diameter of described each optical fiber is 0.5～5mm.
Therefore compared with prior art, the present invention has following beneficial effect:
Darkroom among the present invention can significantly reduce in the surrounding environment other light sources to the influence of photosensitive device, soft light cover can allow the light that enters the darkroom by optical fiber be distributed on the photosensitive device equably, in addition, soft light cover can stop the scattered light in the sunshine to pass through optical fiber, and only allow the logical optical fiber of direct light enter the darkroom, improved the degree of accuracy of whole sensing device.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the synoptic diagram of another angle of the embodiment of the invention.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
As Fig. 1 to the embodiment that Figure 2 shows that a kind of sun light tracking sensing device of the present invention, comprise base 1, base 1 is provided with four shadow shields 2 that vertically arrange, every adjacent shadow shield 2 is vertical mutually, the outside, below of every shadow shield 2 is provided with for the optical fiber 3 that receives sunshine, the end of each optical fiber 3 is provided with darkroom 4, optical fiber 3 and darkroom 4 all are arranged in the base 1, be provided with soft light cover 5 in each darkroom 4, photosensitive device 6 and data output end, soft light cover 5 is arranged at the middle part in darkroom 4, and photosensitive device 6 and data output end are arranged at the bottom in darkroom 4.
Principle of work is as follows:
1, when the sunshine vertical irradiation, four optical fiber 3 can both receive direct sunlight, direct light is injected in the darkroom 4 by optical fiber 3, shine on the photosensitive device 6 by the soft light cover 5 in the darkroom 4 again, this moment, the light income of four photosensitive devices 6 was identical, and the electric current and voltage data that photosensitive device 6 is sensed are identical.
2, when sunshine does not have vertical irradiation, suppose that sunshine is from the irradiation of shadow shield 21 1 sides top, shadow shield 21 can cover the part sunshine, the direct light of the sunshine that covered this moment can not shine on the photosensitive device 6 by optical fiber 3, soft light cover 5, have only the direct light that is not covered by shadow shield 21 to shine on the photosensitive device 6 by optical fiber 3, soft light cover 5, so the light income difference of each photosensitive device 6, the electric current and voltage data that produce are also different.
When reality was used, when the height of every shadow shield 2 is 20～200mm, and the diameter of each optical fiber 3 was when being 0.5～5mm, and the sensing effect of whole sensing device is better.
More than technical scheme that the embodiment of the invention is provided be described in detail, used specific case herein principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
