The Chinese patent with the authorization announcement number CN217826410U is a self-cleaning device for an aquaculture pond applied for by the applicant, which is installed in a circular aquaculture pond, and a water outlet is provided at the bottom center of the circular aquaculture pond. The self-cleaning device includes a central cylinder, a sleeve and a rotating support rod, the central cylinder is vertically fixed at the water outlet, a plurality of through holes are provided on the outer wall of the central cylinder at intervals, the sleeve is sleeved on the outside of the central cylinder, a plurality of open grooves are provided on the outer wall of the sleeve, at least one brush strip 1 is provided on the inner wall of the sleeve, the brush strip 1 is parallel to the central axis of the central cylinder, and the inner side of the brush strip 1 contacts the outer surface of the central cylinder, the bottom side of the sleeve is fixedly connected to the rotating support rod, and the bottom surface of the rotating support rod is fixedly provided with a brush strip 2 that contacts the bottom surface of the circular aquaculture pond.

[0003] In the above patent, driven by the flow of water in the aquaculture pond, the rotating support rod and its sleeve rotate around the central cylinder, and the brush strips respectively scrub the bottom of the circular aquaculture pond and the outer wall of the central cylinder. However, this patent cannot clean the inner wall of the central cylinder, and the dirt and bacteria on the inner side of the central cylinder will block the filter screen and affect the circulation of the water flow, and the remaining bacteria will also pollute the circulating water. In addition, this patent can only clean some dirt such as sludge that can pass through the anti-escape net, and it is difficult to clean and collect some solid dirt such as dead fish and shrimp shells that cannot pass through the anti-escape net. For this reason, we propose a dirt cleaning device for an aquaculture pond. Utility Model Content
