Abstract
The utility model relates to a cross-shaped light barrier forking sensor, which consists of a square box, a cross-shaped light barrier and four surface light sensing elements, wherein the cross-shapedlight barrier separates the four surface light sensing elements. When sunlight non-perpendicularly radiates on the upper surfaces of the four surface light sensing elements, because of the light-blocking function of the cross-shaped light barrier, the increasing amount of light intensity received by the surface light sensing element at one side of the cross-shaped light barrier is equal to the decreasing amount of light intensity received by the surface light sensing element at the other side of the cross-shaped light barrier, and thereby, the tracking accuracy for the sunlight is increased;and the device can be used for various sunlight collection devices and achieves the automatic tracking of sunlight collection.
Description
Affiliated technical field:
The utility model relates to a kind of solar energy sensor technology, particularly a kind of cross light barrier fork sub sensor that can be used for sun light tracking.
Background technology:
Sun power is a kind of clear energy sources, and solar energy power generating is a kind of main mode of human use's sun power.The generated energy of solar panel is relevant with solar angle, generated energy maximum when light is vertical with solar panel.The fixed form generating that present solar photovoltaic generation system generally adopts adopts the autotrack mode generating can improve generated energy 37%, can reduce cost more than 25%.The core technology of automatic tracking system depends on the structure of sensor and the performance of signal processing circuit.Existing technical scheme has clock type and four picture limit photo-electrics at present, and there is the defective that following range is little, sensitivity is low, error is big in they.
The utility model content:
There is the defective that following range is little, sensitivity is low, error is big in order to overcome existing sun-tracking sensor, prior art is improved, proposed the sun light tracking sensor that a kind of following range is big, highly sensitive, tracking error is little.
The technical solution of the utility model is: so that rectangular box is centrosymmetric four face photoinduction elements have been installed in a rectangular box, on four face photoinduction elements, a cross light barrier has been installed so that rectangular box is centrosymmetric, cross light barrier lower end is fixed on the interior bottom surface of rectangular box, cross light barrier and rectangular box four limits join, the upper end of cross light barrier exceeds the certain distance of sensing element upper surface, the cross light barrier is kept apart four face photoinduction elements mutually, and the upper surface of four face photoinduction elements at grade.When sunray vertical irradiation during at four face photoinduction element upper surfaces, the received light intensity of four face photoinduction elements is equal substantially, if when sunray and four face photoinduction element upper surface out of plumb, will cause the received light intensity of each face photoinduction element unequal, because the effect of being in the light of cross light barrier, the light intensity that the face photoinduction element of cross light barrier one side is received increases, the light intensity that the face photoinduction element of opposite side is received reduces, and the recruitment of a side equals the reduction of opposite side, sensor of the present utility model drives topworks according to the difference of two apparent surface's light intensity signals, as long as just work of sunshine is arranged, following range is wide, highly sensitive.Reasonable in design, the reliable operation of the utility model has bigger promotional value.
