Embodiment Construction

[0019] For the automatic tracking technology of the fixed photoreceptor in the solar concentrator, it still needs to solve the problem of the deviation of the solar hour angle caused by the earth's rotation and the deviation of the sun's declination angle caused by the revolution. In order to solve this problem, the present invention has designed following technical scheme:

[0020] The solar polar axis type automatic tracker of the present invention includes a solar hour angle tracking mechanism, a declination angle tracking mechanism, and a concentrator 61 inclined to face the sunlight, wherein the solar light signal is arranged on the light receiving surface of the concentrator 61 Collector 1; the lower end of the concentrator 61 is fixed by a multi-stage shaft connection structure, which provides the concentrator 61 with degrees of freedom for solar hour angle rotation and declination adjustment; the solar hour angle tracking mechanism includes an arc track And be arranged...

Abstract

The invention provides a sunlight polar axis type automatic tracking device, comprising a solar hour angle tracking mechanism, a declination angle tracking mechanism and a sunlight condenser inclining toward sunlight, wherein a light receiving face of the condenser is provided with a sunlight signal collector; the lower end of the condenser is fixed by a multi-section type axial connection structure; and the multi-section type axial connection structure provides degrees of freedom for the condenser for rotating a solar hour angle and adjusting a declination angle. Through adoption of the sunlight polar axis type automatic tracking device, designed on the condition that a light receptor is stationary, sunlight signals which are input at real time can be processed and a corresponding instruction is output according to a processing result, so that an omnibearing high-accuracy sunlight automatic tracking function is realized. By utilizing a method for manufacturing a slide channel according to a radian of a running track of the sun every day, the working time of a vertical motor is greatly reduced and the energy source is saved.

Description

technical field [0001] The invention belongs to the technical field of solar energy applications, and relates to a two-dimensional solar light automatic tracking device, in particular to a solar light polar axis automatic tracker, which adopts a polar axis automatic tracking method to realize the concentration of light under the condition that the light receiving body is fixed. The optical device has a high-precision automatic rotation tracking function. Background technique [0002] The development and utilization of new energy represented by solar energy has become one of the effective methods for human beings to solve the energy crisis, and it has also become the basic energy decision of my country's sustainable development strategy. However, due to the low energy density of sunlight (1KM / M 2 ) and the direction changes periodically over time. In order to improve the utilization rate of solar energy, the most common way to use more efficient sunlight for direct lighting ...
