[0038] The drainage trough 3 is located outside one end of the breeding pond body 1 provided with the feces discharge passage 6, and the drainage trough 3 is connected with the feces discharge passage 6, so that the water and feces discharged from the feces discharge passage 6 can flow into the drainage trough 3. Generally, the horizontal height of the bottom surface of the drainage trough 3 is lower than the horizontal height of the bottom surface of the breeding pond body 1, so that when the water enters the drainage trough 3 from the breeding pond body 1, it has potential energy in height.

[0039] A cleaning trough 7 is arranged between the drainage trough 3 and the breeding pond body 1 . The cleaning trough 7 is located at the top of the breeding pond body 1 , and a blocking net 4 is also arranged in the cleaning trough 7 .

[0040] Specifically, the water flow rate entering the breeding pond body 1 from the water inlet 5 is greater than the water flow rate at the feces discharge channel 6, so that the liquid level in the breeding pond body 1 is located in the middle of the barrier net 4, and the water overflowing from the middle of the barrier net 4 also flows into the drainage trough 3.

[0041] In this embodiment, a water inlet 5 is opened at the bottom of one end of the breeding pond main body 1, and a feces discharge channel 6 is set at the bottom of the other end of the breeding pond main body 1. When new water flows into the breeding pond main body 1, a certain impact force will be generated at the bottom of the breeding pond main body 1, thereby impacting the feces deposited at the bottom of the breeding pond main body 1.

[0042] The new water entering the breeding pond body 1 drives the flow of old water in the breeding pond body 1, driving the old water to flow out from the feces discharge channel 6. During this process, the fluid flow rate in the feces discharge channel 6 is fast and the pressure is small, so that the feces flows with the fluid and is discharged from the feces discharge channel 6.

[0043] In addition, by setting the isolation net 2 in the breeding pond body 1, the sturgeons are prevented from escaping from the water inlet 5 or the feces discharge channel 6. The cleaning tank 7 can be provided to carry away the debris floating on the liquid surface by the water flow, and the blocking net 4 can be provided to prevent the sturgeons from escaping from the cleaning tank 7.

[0044] Through this technical solution, the purpose of automatically cleaning the feces deposited at the bottom of the breeding pond body 1 is achieved by utilizing the characteristics of the water flow.

[0049] In another specific embodiment:

[0050] The cleaning system also includes a push rod 8, a guide wheel 9, a pull rope 10, a handle 11 and a connecting shaft 12. Specifically, the push rod 8 is located on the bottom surface of the breeding pond body 1, and the two ends of the push rod 8 are respectively close to the two sides of the breeding pond body 1, and the push rod 8 can reach the inside of the water inlet 5.

[0051] There are two pull ropes 10 , which are respectively arranged on two ends of the push rod 8 .

[0052] In addition, there are eight guide wheels 9, four guide wheels 9 are respectively arranged on both sides of the breeding pool body 1, and all guide wheels 9 on both sides of the breeding pool body 1 are arranged symmetrically. Taking one side of the breeding pool body 1 as an example, two guide wheels 9 are respectively arranged at both ends of the bottom of the breeding pool body 1, and both are located below the isolation net 2, and two guide wheels 9 are respectively located on both sides of the top of the breeding pool body 1, and one guide wheel 9 located at the top of the breeding pool body 1 is also connected to one end of the handle 11.

[0053] The handle 11 is a Z-shaped structure, and the handles 11 are symmetrically arranged on both sides of the breeding pond body 1 .

[0054] The two guide wheels 9 connected to the two handles 11 are connected via a connecting shaft 12 , so that the two guide wheels 9 are respectively arranged at two ends of the connecting shaft 12 .

[0055] Among them, a guide wheel 9 located at the bottom of the breeding pond main body 1 is located outside the breeding pond main body 1, and the guide wheel 9 is close to the water inlet 5.

[0056] The two pull ropes 10 are arranged in a symmetrical structure and are respectively wound around all the guide wheels 9 on the same side of the breeding pond body 1, and the pull ropes 10 also pass through the water inlet 5.

[0057] In this embodiment, the cross section of the push rod 8 is an L-shaped structure, and two ends of the pull rope 10 are respectively connected to two sides of the push rod 8 and close to the bottom of the push rod 8.

[0058] By providing the push rod 8 , the feces at the bottom of the breeding pond body 1 can be regularly pushed to the feces discharge channel 6 , especially the feces adhered to the bottom of the breeding pond body 1 .

[0059] During operation, one of the guide wheels 9 is rotated by the handle 11, so that the pull rope 10 is driven by the guide wheel 9 to move together, thereby pulling the push rod 8 to move at the bottom of the breeding pond body 1. After each operation is completed, the handle 11 is rotated in the opposite direction to make the push rod 8 located in the feed inlet. Generally, a stopper is provided in the feed inlet to limit the position of the push rod 8.
