Self-cleaning solar energy heating tube

Abstract

The invention relates to a self-cleaning solar energy heating tube. The self-cleaning solar energy heating tube comprises a transparent tube and a flow guide tube. The lower portion of the transparent tube is sleeved with a water suction barrel in a fastened mode. The water suction barrel is covered with an annular-barrel-shaped elastic air bag made of transparent materials. A pushing ring is installed at the top of the elastic air bag. An air exhaust hole communicating with the elastic air bag is formed in the pushing ring. The transparent tube is further sleeved with a driving spring, the lower end of the driving spring is fixed to the pushing ring, and the upper end of the driving spring is limited by a ratchet tooth. A cleaning ring is further movably installed above the driving spring, and the transparent tube is sleeved with the cleaning ring. A permanent magnet ring is fixedly installed on the lower ring surface of the cleaning ring. The heating tube can periodically clean itself while collecting heat, the manual inspection period is effectively prolonged, and solar energy is used more conveniently.

Description

technical field [0001] The invention relates to an accessory of a solar water heater, in particular to a solar heating tube. Background technique [0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air Source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; however, traditional solar water heaters still need to pay attention to many problems during use: First, it needs regular system drainage to prevent pipelines At the same time, the water tank needs to be cleaned regularly to ensure clean water quality; second, the solar heating tube needs to be cleaned and wiped regularly to ensure high light transmi...

[0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air Source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; however, traditional solar water heaters still need to pay attention to many problems during use: First, it needs regular system drainage to prevent pipelines At the same time, the water tank needs to be cleaned regularly to ensure clean water quality; second, the solar heating tube needs to be cleaned and wiped regularly to ensure high light transmittance; at the same time, the cleaning work should be done in the early morning or evening when the sun is not strong and the temperature is low To prevent the transparent tube outside the heat collecting tube from being crushed by cold water; third, it is necessary to regularly check the vacuum degree of the heat collecting tube to ensure the heat preservation and heat conduction effect of the heat collecting tube; the regular cleaning of the solar heating tube is one of the more tedious daily tasks One, but there is still no better solution
