Efficient solar thermal collector with pressure relief function

Abstract

The invention relates to an efficient solar thermal collector with a pressure relief function. The collector comprises a mounting plate, two water tanks and at least two thermal collecting tubes, andfurther comprises a cleaning mechanism and at least two pressure relief mechanisms, wherein the cleaning mechanism comprises a power assembly, a rotating shaft and at least two cleaning assemblies, the pressure relief mechanisms comprise pressure relief tubes, sealing sleeves, lifting tubes, seal rings, springs, through holes and at least two air-jet tubes, the power assembly comprises a power cylinder, a water inlet tube, a paddle, a driving shaft, a fixed bearing, a driving wheel, a driving belt and a driven wheel, the cleaning assembly comprises a connecting wire, a moving sleeve, a cleaning brush and an elastic rope. According to the efficient solar thermal collector with the pressure relief function, the thermal collecting tubes can be cleaned through the cleaning mechanism, the efficiency of solar energy absorbing by the thermal collecting tubes is improved, the heating efficiency of the thermal collector is improved, pressure inside the thermal collector can be removed through the pressure relief mechanisms, and the working reliability of the thermal collector is improved.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to a high-efficiency 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.

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.
