Abstract
The utility model provides a ray filtering device for tracking a sun, which solves the problem that a photosensitive sensor utilized by a photoelectric sun tracker is susceptible to failure during detection when sunrays are stronger. A plurality of photoelectric tubes in the utility model are mounted on two sides of a closed vessel; ray shining openings are symmetrical formed on two sides of the closed vessel; ray filtering devices are arranged at the ray shining openings symmetrically formed on two sides of the closed vessel; and the ray filtering devices are symmetrically arranged in sequence from high to low through ray transmission films with different ray transmittance according to the magnitude of ray transmittance.
Description
Technical field:
The utility model relates to solar utilization technique, is specifically related to solar tracking technical field in the solar energy system.
Background technology:
When non-renewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem became the bottleneck of restriction international community economic development day by day, more and more countries came into effect " sunlight program ", and the exploitation solar energy resources is sought the new power of economic development.Solar energy more and more causes people's attention as a kind of reproducible new forms of energy.Photovoltaic generation is a kind of mode that solar energy utilizes, and the effect of and environmental protection energy-conservation because of it is subjected to paying attention to widely.
At present, various types of solar tracking devices emerge in an endless stream, but comparatively commonly used be the photoelectric type sun tracker.Its critical piece is a kind of light sensor that utilizes light action to make the conductivity marked change of semi-conducting material.Domestic photoelectric tracking commonly used at present has gravity type, electromagnetic type and electrodynamic type solar tracking device, and these photoelectronic tracking devices all use light sensor.Usually in these solar energy tracking apparatuses, a plurality of light sensor symmetries are installed in the both sides of closed container, the both sides of closed container all have the light of symmetry to be shining into opening, when two side planes of closed container and sunray are not parallel, the light sensor of the both sides of closed container does not wait because of being subjected to solar radiation intensity, the electric current of its output will have deviation, and deviation signal is amplified through amplifying circuit, adjust angle by servomechanism and make the tracking means aligning sun finish tracking.
At present, the light sensor of the employed most of types of photoelectric type sun tracker is when sunray is very strong, even the light intensity of a side backlight of closed container also makes light sensor reach or surpass measuring range, though this moment, there was the equation of light in the both sides of closed container, but the light sensor of both sides all will reach simultaneously or exceed measuring range, promptly can there be deviation signal yet, thereby causes detection malfunctioning.In view of above reason, the utility model proposes a kind of light filtering apparatus of solar tracking that is used for to solve problem mentioned above.
Summary of the invention:
Problem at above-mentioned photoelectric type sun tracker existence, the utility model proposes a kind of light filtering apparatus that is used for solar tracking, it is characterized in that monosymmetric light at closed container is shining into opening the light filtering apparatus is set, filtering apparatus by the light-transmissive film of different light transmittances according to light transmittance height symmetric arrays in turn from high to low.When sunlight was very weak, both sides were had only very faint resolution capability by the light sensor that the low light-transmissive film of light transmittance blocks, and the light sensor that both sides are blocked by the high light-transmissive film of light transmittance will play main judgement effect.When sunlight is very strong, the light sensor that both sides are blocked by the high light-transmissive film of light transmittance all will reach or surpass measuring range, and the light sensor that both sides are blocked by the low light-transmissive film of light transmittance will play main judgement effect.Thereby by the measurement of the utility model realization to the sunlight of bigger range of light intensity.
The technical scheme that its technical problem that solves the utility model adopts is: the both sides that are installed in closed container of a plurality of light sensors, the both sides of closed container all have the light of symmetry to be shining into opening, be shining into opening at the monosymmetric light of closed container the light filtering apparatus be set, filtering apparatus by the light-transmissive film of different light transmittances according to light transmittance height symmetric arrays in turn from high to low.
Description of drawings:
Accompanying drawing is closed container both sides light filtering apparatus perspective diagrams
Among the figure 1: closed container, 2: light is shining into opening (bilateral symmetry) 3: the filter coating that light transmittance is the highest, 4: the filter coating that light transmittance is minimum
Embodiment:
In the embodiment shown in the Figure of description, the symmetry of a plurality of light sensors is installed in the both sides of closed container (1), the both sides of closed container (1) all have the light of symmetry to be shining into opening (2), be shining into opening (2) at the monosymmetric light of closed container (1) the light filtering apparatus be set, filtering apparatus by the light-transmissive film of different light transmittances according to the light transmittance height by the highest filter coating of light transmittance (3) to the minimum filter coating of light transmittance (4) symmetric arrays in turn.
Claims (1)
1. light filtering apparatus that is used for solar tracking, it is characterized in that: be shining into opening at the monosymmetric light of closed container the light filtering apparatus be set, filtering apparatus by the light-transmissive film of different light transmittances according to the light transmittance height from high to low in turn symmetric arrays form.
