In this example, the power source adopts a handle 5054 structure for manual rotation. Of course, according to needs, the power source can also adopt a servo motor to facilitate electric adjustment of the rotation angle of the baffle assembly 503.

[0043] When the power source is a handle 5054 structure, the part of the main shaft 5051 extending out of the translation frame 501 is fixedly connected to the positioning plate 5055, and the positioning plate 5055 is installed with a pin rod 5056.

The water in the fish-free area is transported to the sewage tank 2 through the drainage pipe 6, and then discharged into the treatment tank 4 for treatment and then discharged into the clean water tank 3. The water in the clean water tank 3 is returned to the fish-free area, and then the water in the fish area is transported to the sewage tank 2, and then the baffle assembly 503 is rotated to open the through slot 502, so that the water in the fish-free area flows into the fish area and the fish driving mechanism 5 moves back to the original position. There is no need to pick up the fish, and the water in the breeding pond 1 with different fish numbers can be changed. At the same time, the separation space can be freely adjusted according to the size of the fish in the breeding pond 1, and the through slot 502 can discharge a large amount of water, which greatly reduces the crushing injury of the fish and ensures the normal growth of the fish.
