Description
Technical field
The utility model belongs to the solar energy generation technology field, especially relates to a kind of sun-tracking sensor that is used for the sun light tracking electricity generation system.
Background technology
Sun-tracking sensor is the vitals of solar tracking system, and the height of solar tracking system precision depends primarily on the sensitivity of sun-tracking sensor.At present traditional tracking sunshine system (generally be use the one-mast support formula, adopt disc type but also have) is an employing light intensity induction pick-up.The light intensity induction pick-up is when having cloud, because of calculating intensity of illumination after not stopping to seek light source causes power consumption big.And cloud is when leaving, and taking time harmonizes follows the tracks of, and has influenced the generated energy of sun power, has also increased power consumption simultaneously.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of sun-tracking sensor is provided, it is simple in structure, and is reasonable in design, simple operation, cost is low, the precision height, dependable performance efficiently solves the sun light tracking problem, result of use is good, is convenient to promote the use of.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of sun-tracking sensor; it is characterized in that: comprise base plate and four blocks of light transmissive material plates that are arranged on the base plate; described light transmissive material plate is overlapped to form similar " people " font between any two; the upper end center position of four blocks of light transmissive material plates is separately installed with a photovalve; four photovalves are respectively towards east; south; the west; the north four direction is installed; the top of described photovalve is provided with the semicircular protective cover that is made with transparent material, and the lower edge and the base plate of described protective cover join.
Above-mentioned sun-tracking sensor is characterized in that: the bottom of described base plate is coated with black pigment.
Above-mentioned sun-tracking sensor is characterized in that: described light transmissive material plate is made by optical material.
Above-mentioned sun-tracking sensor is characterized in that: the bottom of described light transmissive material plate is coated with black pigment except that the zone that photovalve is installed.
Above-mentioned sun-tracking sensor is characterized in that: described protective cover is made by transparent material.
The utility model compared with prior art has the following advantages:
1, the utility model comprise base plate, be arranged on the base plate and be overlapped to form four blocks of light transmissive material plates of similar " people " font between any two, the protective cover that is installed in the photovalve of four blocks of light transmissive material plates upper end and is arranged on the photovalve top constitutes, simple in structure and novel in design rationally.
2, simple operation of the present utility model, cost of manufacture are low.
3, the utility model adopts optical material to make the light transmissive material plate, cooperate photovalve, utilize the principle of light total reflection on the light transmissive material plate, propose four direction and responded to the improvement of sunshine simultaneously, it is that precision is low by the light intensity induction pick-up that tradition is followed the tracks of, and the utility model utilizes the incident ray total reflection principle, not only improved tracking accuracy greatly, and the reliability height of equipment.
4, the utility model has reduced the power consumption of system, has improved the efficient of solar electrical energy generation, energy savings, and result of use is good, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
As depicted in figs. 1 and 2, the utility model comprises base plate 1 and four blocks of light transmissive material plates 2 that are arranged on the base plate 1, described light transmissive material plate 2 is overlapped to form similar " people " font between any two, the upper end center position of four blocks of light transmissive material plates 2 is separately installed with a photovalve 3, four photovalves 3 respectively towards east, south, west, north four direction installs, receive sunshine simultaneously, and the output corresponding signal, judge solar direction for extraneous readout equipment; The top of described photovalve 3 is provided with the semicircular protective cover 4 that is made with transparent material, and the lower edge of described protective cover 4 and base plate 1 join.
As depicted in figs. 1 and 2, in the present embodiment, the bottom of described base plate 1 is coated with black pigment, prevents that incident light from causing veiling glare to disturb to photovalve after the base plate reflection, reduces the influence of device interior parasitic light, improves tracking accuracy.Described light transmissive material plate 2 is made by transparent optical material; The bottom of described light transmissive material plate 2 is coated with black pigment except that the zone that photovalve 3 is installed, it considers that mainly parameter has total reflection angle and total reflection angle tolerance, the total reflection angle mainly is to determine that according to the concrete region of installing total reflection angle tolerance has then determined the tracking accuracy of sensor.Described protective cover 4 is made by transparent material, not only can see through sunshine, and system and external environment are isolated, and for internal unit provides a good working environment, improves the serviceable life of sensor.
As shown in Figure 3, the principle of work of the present utility model and the course of work are: four blocks of light transmissive material plates, 2 adult's font structures, respectively towards east, south, west, north, four photovalves 3 of installation receive the sunshine of four direction respectively on it.When the incident of sunshine slave unit top, as A direction light among the figure, the photovalve 3 of four direction all can be sensed sunshine and output signal, when the sun turns an angle, the skew of incident ray generation angle H, as B direction light among the figure (for convenience of description, angle H among the figure is exaggerated), then photovalve 3 still has signal output in the east, and west photovalve 3 is responded to less than sunshine owing to the total reflection effect of light transmissive material plate 2, so there is not signal output, B ' is the emergent ray of light B after 2 reflections of light transmissive material plate among the figure.Other both directions of B ' similarly.Disturb for fear of veiling glare, equipment bay 1 and light transmissive material plate 2 bottoms require to dye black, only leave window at photovalve 3 places.Test by photovalve 3 output signals, just can know the offset direction of light, and then adjust the sun light tracking direction by suitable drive mechanisms to four corners of the world four direction.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
