AI Technical Summary

Technical Problem

Existing solar heating devices tend to accumulate dust, dew, and other foreign matter on the reflector surface at night, affecting the reflection effect and the heating efficiency of the heat transfer medium.

Method used

A solar thermal heating device was designed, comprising a support plate, a reflective lens, a water supply pipe, a bracket plate, a shading component, and a drive component. The drive component moves the reflective lens to follow the sun and automatically shades the reflective lens when the sun sets to prevent the accumulation of foreign objects.

Benefits of technology

It enables automatic adjustment of the reflective lens angle, improves the efficiency of solar heat utilization, and prevents foreign objects such as dust and dew from affecting the reflective lens's performance at night.

Abstract

This invention provides a solar thermal heating device, belonging to the field of solar energy utilization technology. It includes a support plate, a reflective mirror, a water supply pipe, a bracket plate, a shading component, a driving component, and a movable limiting component. Two sets of bracket plates are provided, arranged opposite to each other. The water supply pipe passes through both sets of bracket plates and is fixedly connected to them. The support plate is located outside the water supply pipe and rotatably engages with it. The reflective mirror is installed on the side of the support plate facing the water supply pipe. Compared to existing technologies, this invention enables automatic adjustment of the reflective mirror angle, allowing it to move with the sun, thereby improving solar thermal utilization efficiency. Furthermore, it automatically shades the reflective mirror at sunset, preventing dust, dew, and other foreign objects from falling onto its surface at night and affecting its subsequent performance.
