In specific implementation, water is automatically fed through the water inlet interface according to the growth condition of fish in the aquaculture water tank, or according to aquaculture environment or according to program setting, and seawater entering the aquaculture water tank is taken from a special water taking device configured on the aquaculture ship and enters the seabed deeply, filtered and uniformly allocated.
According to the required water inflow, a control instruction is issued uniformly by a shipborne control system, and the water drainage impeller is started at first and then the water inlet valve is opened. Clean seawater enters the culture water tank through the water inlet pipe, the water inlet valve and the hyperbolic saddle-shaped flow-aiding structure.
The seawater entering the culture water tank is made to flow into a vortex flow field by adopting the following two measures: 1. the water inlet valves are respectively controlled from top to bottom, and the water inlet amount is controlled through different valve opening amounts, so that the water inlet flow rate from the upper layer to the lower layer is orderly reduced; 2. each layer of flow aiding structure gradually slows down from top to bottom, so that the water flow entering the culture water tank is in transition from concentration to diffusion from top to bottom.
As shown in figure 4, the drainage interface comprises two outlets, the high-level drainage pipe at the upper part of the sewage collecting tank side is a conventional outlet, and the lower part of the sewage collecting tank side is a sewage cleaning port which is not opened at ordinary times. An adjustable impeller is arranged in the upper water discharge pipe, and the rotating speed of the impeller is controlled by a ship-borne control system to adjust the water discharge rate according to the required water inflow.

Among these, it is to be emphasized:
1) each layer of water inlet of the water inlet interface is automatically opened and the water inflow is adjusted under the centralized control of a shipborne control system according to the water body environment, the growth state of fish schools and other special requirements;
2) the flow aiding structure is in a hyperbolic saddle shape, the section shape of each flow aiding structure from the upper layer to the lower layer is gradually transited from concentrated to gentle, and finally the culture water body forms a spiral vortex-shaped flow field under the combined action of the diversion trench at the bottom of the culture water tank, so that the water body in the culture water tank is fully exchanged, and the residual bait, excrement and other dirt are concentrated into the bottom dirt collecting trench;
3) the drainage interface adopts two export designs, and conventional drainage adopts high-order drain pipe, and the clear dirty mouth in bottom is used for the filth to discharge, the centralized processing of being convenient for.
The active regulation of the swirling flow effect is realized by regulating the flow of the water inlet valves with different heights; the passive adjustment of the rotational flow effect is realized through the design of a spiral saddle-shaped flow aiding structure which is specially designed and is formed under different heights and the design of a flow guide groove at the bottom of the culture water tank. And then the water body in the culture water cabin is exchanged with the external seawater by the active and passive combined measures, the environment is protected, and pollutants are separated from the conventionally discharged sewage. Meanwhile, the drainage structure is also optimally designed, so that reasonable structural arrangement is obtained for drainage, dirt collection and dirt removal.
