Therefore, in the process of lifting the leakage net 19 and the leakage plate 20, only the aquatic product will be lifted, and the flow of water will not be interfered with, so that the sewage in the inner cavity of the breeding barrel 2 can be completely discharged;

[0026] See also Figure 4 , a plurality of leakage holes 21 are provided on the side of the leakage plate 20, and a telescopic rod 17 is fixedly connected to the bottom end of the leakage plate 20, and one end of the telescopic rod 17 away from the leakage plate 20 passes through the bottom end of the inner cavity of the breeding barrel 2 and is fixedly connected to the output end of the cylinder 16, and the cylinder 16 is fixedly installed at the bottom of the breeding barrel 2; under the telescopic movement of the telescopic rod 17, the leakage plate 20 and the leakage net 19 can be driven to be lifted, and the aquatic products can be driven to be lifted, so that the aquatic products can leave the water temporarily, and harmful impurities in the water are prevented from adhering to the aquatic product body, so that the harmful impurities can flow out through the first water outlet pipe 9;

[0029] See also Figure 1-Figure 2 The pumping mechanism includes a water pump 3 fixedly installed on the periphery of the breeding barrel 2, the water inlet of the water pump 3 is fixedly connected to a water inlet pipe 7, the end of the water inlet pipe 7 away from the water pump 3 passes through the side of one end of the support bracket 5, the water outlet of the water pump 3 is fixedly connected to a second water outlet pipe 8, the end of the second water outlet pipe 8 away from the water pump 3 is perpendicular to the top of the inner cavity of the breeding barrel 2, and one end of the water inlet pipe 7 connected to the water inlet of the water pump 3 is located at a relatively top position in the inner cavity of the sedimentation tank. After the interaction of time and chemical reagents, the impurities in the sewage will be precipitated at the bottom of the inner cavity of the sedimentation tank 1, and the water at the top position of the inner cavity of the sedimentation tank 1 is relatively clean and suitable for the needs of aquatic product breeding. Therefore, when the water inlet pipe 7 extracts water from the inner cavity of the sedimentation tank 1, it extracts water resources suitable for aquatic product breeding, thereby meeting the needs of aquatic product breeding.

[0030] The working principle of the utility model is as follows: when the device is needed to be used to culture aquatic products, the aquatic products can be placed in the inner cavity of the culture barrel 2 for culture. When the sewage needs to be replaced, the cylinder 16 is first driven to make the telescopic rod 17 telescopically move. During the up and down movement of the telescopic rod 17, the leak plate 20 can be driven to move up and down, and then the leakage net 19 can be driven to move up and down. At this time, the aquatic products in the inner cavity of the culture barrel 2 can be lifted under the action of the leak plate 20 and the leakage net 19. At the same time, during the upward movement of the leak plate 20, the closing block 6 can be driven to separate from the bottom of the inner cavity of the culture barrel 2, so that the inner cavity of the culture barrel 2 is in an open state, so that the sewage in the inner cavity of the culture barrel 2 can flow out through the first outlet pipe 9.

[0031] The sewage flows out through the first outlet pipe 9 and enters the inner cavity of the crushing tube 4. At this time, the motor 11 can be driven. The output shaft of the motor 11 can rotate to drive the rotating shaft 12 to rotate, and then drive the multiple rotating rods 13 and the cutting blades 14 to rotate, thereby cutting and crushing the impurities in the sewage flowing into the inner cavity of the crushing tube 4, which can effectively decompose the mineral impurities in the sewage, increase the removal effect of harmful substances, and enhance the purification effect of the sewage in the next step;

[0032] The cut and crushed sewage and impurities will flow into the inner cavity of the sedimentation tank 1 through the discharge pipe 10 for sedimentation. The precipitated sewage can be pumped into the inner cavity of the breeding barrel 2 by the action of the pump 3 to breed the aquatic products again, thereby realizing the recycling of water and achieving the purpose of saving water.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
