Specifically, in the process that a large amount of water is output outwards through the first water outlet pipe 411, a water absorption effect is generated between the upper tray body 42 and the lower tray body 41 through the through hole 4111, so that the water in the bottom area of the water storage space is accelerated to flow into the area between the upper tray body 42 and the lower tray body 41. Since the water in the water storage space flows around clockwise or counterclockwise rotation, the water flowing into the region between the upper tray body 42 and the lower tray body 41 can be effectively discharged through the second water outlet pipe 412. Preferably, the second outlet pipe 412 is transversely arranged, and the inner pipe orifice of the second outlet pipe 412 is formed on the inner wall of the lower tray body 41 and is positioned at one side of the first outlet pipe 411. Specifically, the water outlet direction of the second water outlet pipe 412 may be tangentially arranged along the rotational flow direction of the water in the water storage space, so that the water between the upper tray body 42 and the lower tray body 41 can be quickly discharged from the second water outlet pipe 412.

Preferably, the annular side plate 2 is provided with an overflow hole 21, and the overflow hole 21 communicates with the water tank 51.

Thus, three paths of water outlet can be realized through the top overflow hole 21, the vertically arranged central pipe 43, and the upper disc body 42 and the lower disc body 41 which are arranged at the bottom, so that culture dirt in the water storage space can be discharged in a layered mode, and the water in the water storage space can be purified to the maximum extent.

In addition, according to the design requirement, a vertical flow settling tank 6 can be arranged on the outer side of the annular supporting frame 3, and a sewage discharge pipe 45 is connected with an inlet of the vertical flow settling tank. The specific structure of the vertical flow settling tank 6 can adopt the structural design in the conventional culture technology, and is not limited herein. The residual baits and excrements clamped by the water output through the sewage discharge pipe 45 can be treated by the vertical flow settling tank 6, and then the water treated by the vertical flow settling tank 6 is treated in the biological pond 200 conveyed to the outside so as to save water.

In actual use, according to the difference of fish species, a protective net 7 can be further arranged at the top of the annular supporting frame 3, and cultured fish can be placed through the protective net 7 to jump out of the culture pond.
