[0021] like Figures 1 to 7 As shown, in this embodiment, the present invention includes a breeding pond 1, a sludge collection well 2 disposed at the bottom of the breeding pond 1, an escape-proof net 3 disposed on the sludge collection well 2, and an aeration disc 4 fixedly connected to the upper part of the escape-proof net 3. The sludge collection well 2 is provided with a support ring 5 for fixing the escape-proof net 3. The bottom of the sludge collection well 2 is provided with a sewage pipe 6 and a circulation and emptying pipe 7. The bottom of the escape-proof net 3 forms a protruding edge 31 that engages with the support ring 5. The upper end of the breeding pond 1 is provided with a water inlet pipe 11. The outlet end of the water inlet pipe 11 is provided with a water outlet elbow 12. The water inlet pipe uses the water outlet elbow 12 structure to push the water flow counterclockwise, and the water flow along... The interior of the aquaculture pond 1 rotates counterclockwise, forming a water vortex that carries the uneaten feed and feces suspended in the water toward the middle of the pond. The aeration disc 4 in the middle pushes the water upward during the aeration and oxygenation process. As the water flows upward, a low-pressure space is formed below the aeration disc 4, which absorbs the water flow from the outside and moves toward the escape net 3, thereby sucking in the uneaten feed and feces suspended in the water. The upward surging water spreads from the middle to the surroundings and flows from top to bottom along the interior of the aquaculture pond 1, thereby pushing the uneaten feed and feces accumulated at the bottom of the aquaculture pond 1 toward the escape net 3, improving the absorption and discharge efficiency of uneaten feed and feces and reducing the time that uneaten feed and feces remain in the aquaculture pond 1.

[0022] In this embodiment, the sidewall of the escape-proof net 3 is provided with a plurality of escape-proof sewage discharge holes 32, and the convex edge 31 of the escape-proof net 3 is provided with a plurality of rotating bayonets 33, which are designed to facilitate quick installation and disassembly in daily life.

[0023] In this embodiment, the width of each escape-proof drainage hole 32 is 3-8mm. The 4-6mm escape-proof drainage hole 32 can effectively prevent fish fry from escaping while allowing uneaten food and feces to flow into the sewage collection well 2 for discharge.

[0024] In this embodiment, the support ring 5 is provided with a plurality of protruding posts 51. Each of the protruding posts 51 is corresponding to a rotating latch 33. The protruding post 51 is a screw, and the upper part of the protruding post 51 is formed to limit the engagement with the rotating latch 33.

[0025] In the embodiment, the aeration disc 4 comprises a support 41 and an aeration pipe 42, the support 41 is fixedly connected to the top of the escape-proof net 3, the support 41 is formed with a fixing groove, and the aeration pipe 42 is fixedly connected in the fixing groove.

[0026] In the embodiment, the aeration pipe 42 is in a ring structure.

[0027] In the embodiment, the bottom of the culture pond 1 is formed with a tapered inclined surface.

[0028] The working principle of the utility model is:

[0029] The water flow rotates counterclockwise along the inside of the culture pond 1, forms water flow vortex, drives the residual feed feces suspended in water to accumulate in the middle of the culture pond 1, the aeration disc 4 located in the middle promotes the water flow to move upward in the aeration oxygenation process, because the water flow promotes the low pressure space formed at the position below the aeration disc 4 to move upward at this time, absorbs the water flow to move to the escape-proof net 3 direction from the outside, thereby inhaling the residual feed feces suspended in the water body, the water flow moving upward spreads from the middle to the periphery, flows from top to bottom along the inside of the culture pond 1, thereby promoting the residual feed feces accumulated at the bottom of the culture pond 1 to move to the escape-proof net 3 direction.

[0030] Although the embodiment of the utility model is described with actual scheme, does not constitute the limitation to the meaning of the utility model, for the person skilled in the art, according to the modification of the embodiment of the specification and the combination with other schemes, it is obvious.
