Abstract
The utility model relates to a solar energy automatic-tracking device, which includes a photoelectric element array and a shadow bar, wherein a voltage signal output terminal of each photoelectric element in the photoelectric element array is connected with a control system which is used for calculating the sun position according to the projected length and the angle of the shadow bar on the photoelectric element array, and a control output terminal of the control system is connected with a drive mechanism used for driving a solar energy panel to keep perpendicular to sun light. The solar energy automatic-tracking device provided by the utility model is used for measuring the sun position at a certain time, including the azimuth angle of the sun light in a horizontal plane and the solar elevation. When the sun moves, the shadow bar has the projected angle and the length on the photoelectric element array changed continuously. According to the shadow length and the angle, the sun position can be obtained and contains the azimuth angle of the sun light projected in a horizontal plane and the solar elevation.
Description
Technical field
The utility model relates to a kind of automatic solar energy tracking device, belongs to application of solar.
Background technology
Sun power is subjected to generally paying attention to as a kind of clean energy resource, uses day by day extensive.Present solar water heater, solar cell mostly are fixed.If solar water heater, solar cell can regulate along with moving of the sun towards, make its sensitive surface all the time over against the sun, accept vertical irradiation, then the utilization ratio of sun power can improve about 30%.
The structure of existing automatic solar energy tracking device and control method are complicated, and cost is higher.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, control automatic solar energy tracking device easily.
For solving the problems of the technologies described above, the utility model provides a kind of automatic solar energy tracking device, comprising: optoelectronic component array and the shadow bar that is located on the optoelectronic component array; In the optoelectronic component array voltage signal output end of each photovalve be used for linking to each other according to the length of the projection of shadow bar on optoelectronic component array and the control system of the sunny position of angle calculation, the control output end of control system be used to drive solar panel and keep linking to each other with the vertical driving mechanism of sunray.
Further, described optoelectronic component array is provided with transparent protective shield.
Further, described optoelectronic component array is horizontally disposed with, and shadow bar is located at the centre at the edge, southern side of optoelectronic component array, thereby the projection of guaranteeing shadow bar and makes things convenient for the position of the accurate Calculation sun substantially on optoelectronic component array.
Further, described optoelectronic component array is rectangular, to satisfy the sun when each position, can both form projection on optoelectronic component array.
The utlity model has positive effect: (1) automatic solar energy tracking device of the present utility model is the position of measuring a certain moment sun, comprises position angle and the sun elevation angle of sunray at the surface level inner projection.When the sun moved, angle, the length of shadow bar's projection on optoelectronic component array constantly changed.According to shadow length, angle, can obtain position of sun, comprise the position angle and the sun elevation angle of the projection of sunray in surface level.Subsequently, driving mechanism just can be adjusted the attitude of solar panel, solar water heater etc. by this angle, allows sensitive surface over against the sun, accepts the sunshine vertical irradiation.(2) accept the photovalve that shines upon, the photovalve under the shade, the output difference is very big.By detection, can know angle, the length of shade to all photovalve outputs.In conjunction with size, the setting angle of projecting plane, shadow bar, sunray can obtain at position angle, the sun elevation angle of surface level inner projection.Promptly by this angle, the controlling and driving mechanism action makes sensitive surface over against the sun to control system, accepts vertical irradiation.
