Abstract
A forking sensor with a cross light barrier and a circular beam splitter belongs to a solar photoelectric sensor, consists of a square box, the cross light barrier, four surfaced photosensitive elements and the circular beam splitter, can complete light intensity tracking and acquisition horizontally and vertically, and can be used for various types of solar acquisition equipment to realize automatic tracking for sun light acquisition.
Description
Affiliated technical field:
The utility model relates to a kind of solar energy sensor technology, particularly a kind of Furcating sensor with crossed light barrier and circular beam splitter 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:in a rectangular box with the centrosymmetric face photoinduction element one of having installed of rectangular box, face photoinduction element two, face photoinduction three element and face photoinduction quaternary part, 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 upper surface of sensing element, the cross light barrier is kept apart four face photoinduction elements mutually, the upper surface of four face photoinduction elements at grade, a circular beam splitter sheet has been installed so that rectangular box is centrosymmetric in the upper end of cross light barrier. is when sunray vertical irradiation during at four face photoinduction element upper surfaces; The received light intensity of four face photoinduction elements is substantially equal; If when sunray and four face photoinduction element upper surface out of plumb; Will cause the received luminous intensity of each face photoinduction element unequal; Because the effect of being in the light of cross light barrier and circular beam splitter sheet; The luminous intensity that the face photoinduction element of cross light barrier one side is received increases; The luminous 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 is to drive topworks according to the difference of the surface light strength signal of two opposite face photoinduction elements, 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.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a whole schematic diagram of the present utility model.
Fig. 2 is a whole vertical view of the present utility model.
1. rectangular box among Fig. 1 and Fig. 2,2. cross light barrier, 3. a photoinduction element one, 4. a photoinduction element two, 5. a photoinduction element three, 6. a photoinduction element four, 7. circular beam splitter sheet.
Embodiment
In Fig. 1 and Fig. 2, face photoinduction element one (3), face photoinduction element two (4), face photoinduction element three (5) and face photoinduction element four (6) are installed in the rectangular box (1) so that rectangular box (1) is centrosymmetric, face photoinduction element one (3), face photoinduction element two (4), the upper surface of face photoinduction element three (5) and face photoinduction element four (6) at grade, cross light barrier (2) inserts in the rectangular box (1), the lower end of cross light barrier (2) is fixed on the interior bottom surface of rectangular box (1), the upper end of cross light barrier (2) exceeds face photoinduction element one (3), face photoinduction element two (4), the upper surface of face photoinduction element three (5) and face photoinduction element four (6) and with face photoinduction element one (3), face photoinduction element two (4), face photoinduction element three (5) and face photoinduction element four (6) are kept apart mutually, cross light barrier (2) joins with rectangular box (1) four limit, and the upper end of cross light barrier (2) is with the centrosymmetric circular beam splitter sheet (7) of having installed of rectangular box (1).When the sunray vertical irradiation at face photoinduction element one (3), face photoinduction element two (4), during the upper surface of face photoinduction element three (5) and face photoinduction element four (6), face photoinduction element one (3), face photoinduction element two (4), the received light intensity of face photoinduction element three (5) and face photoinduction element four (6) is equal substantially, if sunray and face photoinduction element one (3), face photoinduction element two (4), during the upper surface out of plumb of face photoinduction element three (5) and face photoinduction element four (6), will cause the received light intensity of each face photoinduction element unequal, because the effect of being in the light of cross light barrier (2) and circular beam splitter sheet (7), the light intensity that the face photoinduction element of cross light barrier (2) one sides 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.
