Tracking control mechanism of array collecting lens

Abstract

The invention discloses a tracking control mechanism of an array collecting lens. The tracking control mechanism comprises a supporting column, an array lens mechanism, a polar axis adjusting mechanism and an elevation adjusting mechanism. The array lens mechanism comprises an array lens shell. The polar axis adjusting mechanism comprises a supporting platform, an extension platform, a polar axis motor, a first worm gear reducer, a polar axis rotating shaft and an elevation rotating shaft. The elevation adjusting mechanism comprises an elevation motor, a second worm gear reducer, an elevation chain wheel transmission mechanism, an elevation lead screw and a chute rack. A plurality of array lens adjusting mechanisms are arranged inside the array lens shell and comprise array lenses, supporting parts, Y rotating shafts, connecting rods, X rotating shafts, gears and cylindrical racks. Due to the fact that the tracking mode of the polar axis adjusting mechanism and the elevation adjusting mechanism is adopted in the array lens mechanism, tracking accuracy is high; compared with a traditional two-dimensional tracking mode, the tracking control mechanism has the advantages that tracking frequency of the motors is reduced, energy and power are saved, the number of adopted motors is reduced, and the complex process of manufacturing concave mirrors is not needed.

Description

technical field [0001] The invention relates to a condenser tracking mechanism, in particular to an array condenser tracking control mechanism. Background technique [0002] The development and utilization of solar energy has broad prospects, and the comprehensive and efficient utilization of solar energy is the goal pursued by people engaged in the field of solar energy development. The tracking efficiency of the solar tracking method in the one-dimensional direction is poor. The traditional photovoltaic dual-axis tracking mechanism realizes the track tracking of the solar energy through two-dimensional tracking in the latitude and longitude directions. Although this method can ensure the tracking accuracy, it has complex structures, high failure rates, The disadvantages such as high cost are difficult to be applied in real life. The trajectory of the sun can be regarded as the change of the solar hour angle caused by the earth's rotation during the day, and the change of ...

AI Technical Summary

Problems solved by technology

The tracking efficiency of the tracking device by tracking the solar hour angle and declination angle is high, but due to the small change range of the declination angle, and the system has the problem of installation angle

In the existing technology, the system design for simultaneous tracking in these two directions cannot be well coordinated

As a result, the tracking accuracy of some devices is not enough, and the structure of some devices with high tracking accuracy is too complicated

[0003] In the field of solar concentrating tracking, the mirror is traditionally made into a concave mirror, but the process of making the entire large mirror into a concave surface is very complicated, which further restricts the development of concentrating devices with larger mirrors
