Sun Tracker Tracking Accuracy Infrared Detection System

Abstract

The invention provides a detection system measuring tracking precision of a solar tracker. The detection system comprises a shading housing, a support, a direct light detection device and a deviation angle metering disc. The direct light detection device further comprises a direct light correction indication board, a buzzer, a miniature laser emitter, and a detection system main body. The shading housing and the support are integrated into one body. The direct light detection device and a transmission device are integrated into one body, and are fixed at the top end of the support through a connecting piece. The central line of the direct light detection device in the vertical direction is coincided with the central line of the shading housing, and passes through the central point of the deviation angle metering disc. The direct light correction indication board is disposed on a light-receiving surface of the direct light detection device in a parallel manner. The deviation angle metering disc is located at the bottom of the support, and is connected with the shading housing. When light directly enters into the precision detection system of the solar tracker, a current deviation angle can be calculated. The precision detection system of the solar tracker can be used in precision measurement of various types of sun-tracking systems.

Description

technical field [0001] The invention relates to the field of solar energy applications, in particular to a detection device for the tracking accuracy of a sun tracker, especially a detection device that can quickly determine the tracking accuracy manually and can measure the tracking accuracy to 0.1°. Background technique [0002] At present, the known types of sun trackers include clock type, program control type, differential pressure type, controlled release type, and photoelectric type, among which the principle structure of the differential pressure type and controlled release type sun tracker is relatively complicated; the clock type and program controlled type There is a cumulative error in the tracking device and it cannot be automatically eliminated; the photoelectric tracking device is more accurate in tracking, the principle is simple, and it is easy to implement, but it cannot continuously track the sun's movement. In summary, the tracking error of the existing tr...

[0002] At present, the known types of sun trackers include clock type, program control type, pressure difference type, control release type, photoelectric type, etc., among which the pressure difference type and control release type sun tracker have a more complicated principle structure; clock type and program control type There is a cumulative error in the tracking device and it cannot be automatically eliminated; the photoelectric tracking device is more accurate in tracking, the principle is simple, and it is easy to implement, but it cannot continuously track the sun's movement. To sum up, the tracking error of the existing tracker is inevitable, and Although the longest design life of existing sun trackers can reach 25 years, with the increase of running time, the tracking accuracy may decrease. Therefore, it is necessary to design a high-precision tracker that can confirm the tracking accuracy at any time and is easy to carry , and a detection system that can provide data for the optimal design and technical improvement of the sun tracker is particularly important
