A solar heat collector with pressure relief function

Abstract

The invention relates to a solar heat collector with a pressure relief function, which includes a mounting plate, two water tanks and at least two heat collecting tubes, and also includes a cleaning mechanism and at least two pressure relief mechanisms. The cleaning mechanism includes a power assembly, a rotating shaft and At least two cleaning components, the pressure relief mechanism includes a pressure relief pipe, a sealing sleeve, a lifting pipe, a sealing ring, a spring, a through hole and at least two air injection pipes, and the power assembly includes a power cylinder, a water inlet pipe, a paddle, a drive shaft, Fixed bearings, driving wheels, transmission belts and driven wheels, cleaning components include connecting wires, moving sleeves, cleaning brushes and elastic ropes, in this solar collector with pressure relief function, the heat collecting tube can be cleaned by the cleaning mechanism, improving The efficiency of the heat collecting tube absorbing solar energy is improved, the heating efficiency of the heat collector is improved, and the pressure inside the heat collector can be removed through the pressure relief mechanism, which improves the reliability of the heat collector.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to a solar heat collector with pressure relief function. Background technique [0002] A solar collector is a device that converts the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. Due to different purposes, collectors and their matching systems are divided into many types with different names, such as solar cookers for cooking, solar water heaters for hot water, solar dryers for drying items, solar dryers for Solar furnaces for melting metals, as well as solar houses, solar thermal power plants, solar desalination plants, and more. [0003] When the solar heat collector of the prior art is in use, if a large amount of dust accumulates on the surface of the heat collector, it will affect the efficiency of the heat collector to absorb solar energy...

AI Technical Summary

Problems solved by technology

[0003] When the solar heat collector of the prior art is in use, if a large amount of dust accumulates on the surface of the heat collector, it will affect the efficiency of the heat collector to absorb solar energy and reduce the heating efficiency of the heat collector. Not only that, the solar heat collector of the prior art When the collector is in use, if the internal temperature of the collector is too high, the water inside the collector will evaporate into water vapor, which will increase the internal pressure of the collector and greatly affect the sealing performance of the collector.
