The working principle of the invention is as follows:
when the invention is used, the air inlet control valve on the air inlet pipeline is opened, the aeration control valve 15 on the aeration device is closed, at the moment, the air output by the high-pressure air source 6 enters the pontoon 2, after the air enters the pontoon 2, the water in the pontoon 2 is discharged outside the pontoon 2 through the water interface 21, thereby improving the buoyancy of the pontoon 2 until the net cage 1 floats upwards, the aeration control valve 15 is opened, the air in the pontoon 2 and the air output by the high-pressure air source 6 both flow into the aeration device in the net cage 1 through the aeration control valve 15, and meanwhile, the external water flows into the pontoon 2, so that the buoyancy of the pontoon 2 is reduced until the net cage 1 is submerged.
The invention is provided with a water level controller 3, wherein an outer floating ball 31 and an inner floating ball 33 in the water level controller 3 rise and fall along with the rise and fall of the liquid level inside and outside a net cage 1, when the net cage 1 is submerged to cause the outside water level to be higher than the inside water level, the outer floating ball 31 rises, the inner floating ball 33 falls, a connecting rod 35 inclines inwards, a water level difference pointer 36 points inwards, a signal sensor 37 fixed at the top of the water level difference pointer 36 converts a pointer position signal into an electric signal, a controller 38 connected with the signal sensor 37 converts the signal and outputs a water level difference signal to a control system, and the control system further controls the opening and closing of a related valve; similarly, when the cage 1 rises to cause the inner water level to be higher than the outer water level, the inner float 33 rises and the outer float 31 descends, the connecting rod 35 is inclined outwards, the water level difference pointer 36 points outwards, the signal sensor 37 fixed on the top of the water level difference pointer 36 converts the pointer position signal into an electric signal to be output to the controller 38, and the controller 38 converts the signal and sends the signal to the control system to control the opening and closing of the relevant valve.

When the quality of the culture water body in the net cage 1 is poor, the aeration control valve 15 is closed to suspend the aeration into the net cage 1, the gas of the high-pressure gas source 6 enters the pontoon 2 and discharges the water in the pontoon 2, so that the water displacement is increased, the buoyancy is increased and the net cage 1 is pushed to rise, when the water level difference pointer 36 in the water level controller 3 shows that the set water level difference is reached, the signal sensor 37 sends a signal to enable the control system to control and open the sewage control valve 53, and food residues and fish feces deposited in the sediment hopper 52 pass through the coarse filter screen 51 and are discharged out of the sewage control valve 53 along with water flow, and at the moment, the net cage 1 is further raised by keeping certain buoyancy, so that the stability of the internal and external water level difference is ensured, and sewage in the net cage 1 is continuously discharged to the outside.
When the water discharge amount reaches the requirement, an aeration control valve 15 in the aeration device is opened, gas in the pontoon 2 is discharged into the net cage 1 through the aeration control valve 15, external water enters the pontoon 2 through a water interface 21, so that the water discharge amount is reduced, the net cage 1 is converted into a submerged state from an ascending state, and when the water level difference between the inside and the outside is reduced to a set value, a water level controller 3 sends out a signal to enable a control system to automatically close the sewage control valve 53, so that an external water source is prevented from flowing into the net cage 1 through the sewage control valve 53.
Along with the continuous submergence of the net cage 1, the water level at the outer side of the net cage 1 is slowly higher than the water level at the inner side of the net cage 1, when the water level difference between the inner water level and the outer water level reaches the set requirement, the water level controller 3 sends a signal to enable the control system to open the water supplementing control valve 43, water in a pool outside the net cage 1 enters the sterilizer 42 for sterilization after passing through the filter 41 by using the water level difference between the inner water level and the outer water level, and then flows into the net cage 1 through the water supplementing control valve 43. Along with the continuous submergence of the net cage 1, the purified water source at the outer side continuously injects the purified water into the net cage 1, thereby realizing the replacement of the sewage by the purified water in the net cage 1.
