Collecting lens array tracking control mechanism

Abstract

The invention relates to a collecting lens tracking mechanism, in particular to a collecting lens tracking mechanism with collecting lens array. In the solar condensation tracking field, the traditional lens is a concave lens, but a process of manufacturing a whole large lens surface into a concave surface is quite complex, and development on the lens surface which is used for manufacturing an optical block is restrained. The invention provides a collecting lens tracking control mechanism which is high in tracking precision and high in tracking effect. A plurality of secondary lenses are required to rotate to the two-dimensional direction of a main lens. A main tracking mechanism adopts polar axis-elevation two-dimensional tracking. By the tracking mechanism with the collecting lens array, each line and each row are respectively provided with a driving motor independently, so that the secondary lenses can be adjusted relative to the angle of the two-dimensional direction of the main lens, and the traditional complex manufacturing process using the concave lens is omitted.

Description

technical field [0001] The invention relates to a condenser mirror tracking mechanism, in particular to a condenser mirror tracking mechanism with an array mirror. 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...

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 problem of installation angle of the system, in the prior art, for the simultaneous tracking in these two directions The system design 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
