Description

Technical Field

[0001] The utility model relates to the technical field of solar energy cleaning, in particular to a solar energy photothermal system self-cleaning device. Background Art

[0002] The solar thermal system is mainly composed of solar collectors, heat exchangers, heat storage, pipelines and control systems. Among them, the solar collector is the core component, which can convert solar radiation energy into heat energy and transfer it to the heat exchanger, and then the heat exchanger transfers the heat energy to the heat storage for storage. The solar thermal system is mainly divided into two types: flat-plate type and vacuum tube type. Among them, the vacuum tube solar collector has higher thermal efficiency and wind resistance.

[0003] According to a publicly disclosed self-cleaning device for a solar thermal system (publication number: CN220119593U), in the above application, the first motor is used to drive the scraper to move on the surface of the vacuum tube to scrape off the debris and part of the dust on the surface of the vacuum tube, and the cleaning agent is sprayed through the nozzle. The second motor is used to drive the cleaning brush to rotate to clean the surface of the vacuum tube after the debris is scraped off, thereby ensuring the cleanliness of the surface of the vacuum tube. No manual operation is required during the cleaning process, which prevents the heat collection efficiency of the vacuum tube from decreasing and improves the photothermal conversion efficiency.

[0004] However, in actual use, the above-mentioned equipment is equipped with a motor to drive the scraper to spray the cleaning agent to clean the surface of the vacuum tube. However, when the vacuum tube is in a season with low temperature, the cleaning function provided by spraying the cleaning agent on the vacuum tube will reduce the heat collection effect of the vacuum tube, thereby reducing the efficiency of photothermal conversion. In view of this, we propose a self-cleaning device for a solar thermal system. Utility Model Content
