AI Technical Summary

Technical Problem

The existing support frame of the parabolic trough collector cannot adjust the angle of the reflector according to the changing direction of light over time, resulting in a decrease in heating efficiency.

Method used

It adopts a combined structure of adjustment components, reflectors, and receivers. Through the design of deflection frame, machine shaft, and reflector, the angle and direction of the reflector are adjusted by deflection motor and rotation motor, and the heat transfer efficiency is improved by combining vacuum glass sleeve.

Benefits of technology

The reflector automatically adjusts its angle and direction according to changes in light, ensuring efficient heating of the trough collector under different lighting conditions and improving the heat collection effect and heating efficiency.

Abstract

This application relates to a trough-type solar collector, belonging to the field of solar collectors. It includes an adjusting component, a reflector, and a receiving component. The adjusting component includes a support and a deflector. The deflector is vertically mounted above the support, and its bottom is rotatably connected to the top surface of the support. The reflector is mounted above the deflector, and includes a shaft and reflective mirrors. The shaft is horizontally rotatably connected to the top of the deflector, and reflective mirrors are symmetrically fixed on the shaft. Multiple brackets are vertically fixed on the shaft, and receiving components are horizontally inserted through these brackets. This application allows for changing the angle of the support frame, thereby changing the angle at which the reflector receives light. This adapts to changes in the direction of light irradiation over time, thus changing the direction of light received by the reflector and ensuring the heating efficiency of the trough-type solar collector.
