After installation, the slip ring 1011 is clamped on the outer surface of the main body 101 and the reflector 1021 is fixedly installed again. Therefore, after the slip ring 1011 is installed, the inner surface of the cleaning cotton 1014 contacts the outer surface of the main body 101. When the heat collecting tube body 100 is fixedly installed on the solar water heater and exposed to the outside world for use, dust falls on it and needs to be cleaned regularly, it is cleaned by the inlet 101. 012 Inject cleaning liquid into the annular channel 1015, and then evenly pass the cleaning liquid in the annular channel 1015 through the installation mesh ring 1013 into the cleaning cotton 1014 through the drainage hole 1016. At this time, the slip ring 1011 slides on the outer surface of the main body 101, driving the cleaning cotton 1014 to contact the surface of the main body 101 for sliding cleaning, and it is convenient for regular cleaning, so that the surface of the heat collecting tube body 100 is cleaner and more efficient in absorbing sunlight and collecting heat, thereby improving the convenience of cleaning and the heat collecting effect of the heat collecting tube body 100 fixedly installed on the solar water heater.
