Tracking sensor for solar concentrator plate

Abstract

The invention discloses a tracking sensor for a solar concentrator plate. The tracking sensor comprises a light-pervious semi-transparent solid bar, a connection tube (3) and a photo-sensitive sensor (4), wherein the light-pervious semi-transparent solid bar is divided into more than two sections, the sections are wrapped and connected through the connection tube (3), and at least a pair of two adjacent sections of the light-pervious semi-transparent solid bar is separated; in the two outermost sections of the light-pervious semi-transparent solid bar, a solar concentration inlet (1) is formed in the top end of one section of the light-pervious semi-transparent solid bar (2), and the other section of the light-pervious semi-transparent solid bar (2) is connected with the photo-sensitive sensor (4). By means of the arrangement of the more than two sections of the light-pervious semi-transparent solid bar, damage of heat conduction to a photo-sensitive component can be effectively isolated. Meanwhile, with the combination of the light-pervious semi-transparent solid bar, effective attenuation is achieved, and light intensity of the photo-sensitive component is achieved. By means of the design, work stability, service life and measurement accuracy of the photo-sensitive sensor are effectively guaranteed.

Description

Technical field [0001] The invention belongs to the field of solar energy utilization, and specifically relates to a tracking sensor for solar concentrators. Background technique [0002] Dish solar system is a more effective form of solar energy utilization. However, in the vicinity of the light spot of the condensing disc, there has not been a good sensor in the prior art to directly and accurately measure the position of the light spot, which affects the tracking of the sun's direction by the concentrating disc, thereby affecting the full utilization of light energy. Summary of the invention [0003] The purpose of the present invention is to provide a solar tracking sensor specially used for high-intensity light detection and photosensitive conversion, so as to be used under conditions near the high-temperature light spot of the concentrating disc. [0004] Specifically, the technical solutions adopted by the present invention are as follows: [0005] A tracking sensor for solar...
