Description

Technical Field

[0001] The utility model relates to the technical field of solar tubes, in particular to a self-cleaning solar tube. Background Art

[0002] Solar water heaters are a type of solar energy device that is currently widely used. They mainly heat water by absorbing sunlight through heat collecting tubes. After long-term use, a lot of dust, dirt or bird droppings will adhere to the heat collecting tubes, blocking the sunlight, thereby affecting the heating efficiency and preventing normal heating.

[0003] An existing tubular solar water heater with a self-cleaning function (publication number: CN213747349U) has at least the following disadvantages:

[0004] When in use, the above patent uses a scraper that is sleeved on the outer surface of the solar heat collecting tube to clean the outer surface of the solar heat collecting tube. Since the scraper can only move back and forth along the solar heat collecting tube, the scraper will be deformed due to thermal expansion and contraction when used for a long time, causing a gap between the scraper and the outer surface of the solar heat collecting tube. As a result, the scraper cannot clean the outer surface of the solar heat collecting tube when it moves back and forth, affecting the cleaning effect. Utility Model Content
