A self-cleaning solar trough collector

Abstract

The invention relates to a self-cleaning type solar energy trough-type heat collector. The self-cleaning type solar energy trough-type heat collector comprises a heat collection pipe and an arc-shaped plate, wherein a truss beam is horizontally arranged above the arc-shaped plate in a suspension manner; the heat collection pipe is hung at the bottom of the truss beam in a parallel manner; sliding rails parallel to the heat collection pipe are laid on the arc-shaped plate under the heat collection pipe; a cleaning device is arranged on the sliding rails; the cleaning device comprises wiper arms and a cleaning brush; the cleaning brush comprises a round brush board; a gap with the width greater than the diameter of the heat collection pipe is arranged at the top part of the brush board; bristles are arranged on the inner circumferential surface of the brush board; the heat collection pipe penetrates into the brush board and the outer surface of the heat collection pipe is contacted with the bristles. The invention has the following benefits: the cleaning device capable of reciprocating in a short distance is added, so that the cleaning of the arc-shaped plate and the heat collection pipe can be completed under the condition of no manual labor; the cleaning effect is ensured; manual labor is saved and the efficiency is improved; moreover, the cleaning device has the functions of expansion and folding, so that the shielding to the arc-shaped plate caused by the wiper arms is avoided.

Description

Technical field [0001] The invention relates to a self-cleaning solar trough heat collector. Background technique [0002] At present, the condenser of the solar trough collector is made of curved glass, and the condensing mirror is not clean and dust will seriously affect the condensing effect, so always keep the mirror clean. Because of the large area of ​​the condenser mirror, it is difficult to clean. Moreover, manual cleaning is generally used, which is slow, time-consuming, labor-intensive, low-efficiency, and wastes water resources. Summary of the invention [0003] In order to solve the above technical shortcomings, the present invention provides a time-saving, labor-saving and high-efficiency self-cleaning solar trough heat collector. [0004] The present invention is achieved through the following measures: [0005] The self-cleaning solar trough heat collector of the present invention includes a heat collection tube and an arc plate, and [0006] A truss beam is arranged ...

AI Technical Summary

Problems solved by technology

[0002] At present, the concentrating mirror of the solar trough collector is made of curved glass. If the concentrating mirror is not clean and dusty, it will seriously affect the concentrating effect, so it is necessary to keep the mirror clean at all times.

Due to the large surface area of ​​the condenser mirror, it is difficult to clean

Moreover, manual cleaning is generally used, which is slow in cleaning speed, time-consuming and laborious, low in efficiency, and wastes water resources.
