The cavity gap of the gas-liquid mixture is a constraint space for lifting the gas-liquid mixture upwards, and the water body moving upwards is blocked by the inclined baffle plate and then pushed to move forwards.
The gas-liquid mixture is restrained in the second cavity, and the specific gravity of the gas-liquid mixture in the space area of the second cavity is smaller than that of the liquid, so that the power for pulling the water body to enter the restrained space is formed, and meanwhile, the power for pushing the water body to enter the culture pond is formed.
The water flow goes through the process from pure liquid to gas-liquid mixture and then to pure liquid,
then the water flow integrally moves forwards in the culture pond; the replacement of the water body from the outside of the culture pond to the culture pond is realized, liquid with dissolved oxygen higher than that in the culture pond is brought in, oxygen is supplemented, and the dissolved oxygen requirement of the cultured organisms in the culture pond is met.
Preferably, partial areas of the side baffles in the ascending area and the descending area of the water flow are higher than the horizontal plane, so that partial water flow is prevented from entering the culture pond; the second cavity (the space for lifting the water upwards in the constrained space) is surrounded by a front baffle, a side baffle, a rear baffle, an inclined baffle and an aeration component; preferably, the upper surface, the lower surface and the side rear surface of the cavity II are through; preferably, the height of the second cavity is 0.5-3.0m, and the upper edge of the front baffle is 0.01-0.5m below the water surface.

More preferably, the aeration assembly is a detachable assembly, so that the maintenance and the repair of the aeration assembly are convenient. The water replenishing source for the water body to lift the space upwards is from the lower part and/or the upper rear part of the aeration assembly. In some embodiments of the invention, the aeration assembly is 1.0 to 10.0m long and 0.05 to 0.8m wide.
Preferably, the length of the bottom baffle is prolonged to the position below the aeration assembly, so that water at the lower side is prevented from being supplemented upwards, the water enters the cavity II from the rear side, and water flow is lifted upwards.
Preferably, the water inlet end of the water pushing system is provided with a blocking net for blocking weeds, duckweeds and floating impurities from entering the aeration cavity and further entering the culture pond, so as to prevent blocking holes blocking the fishing net.
Preferably, the front baffle, the rear baffle, the side baffles or the bottom baffle is made of metal, plastic, aluminum-plastic plate or glass fiber reinforced plastic.
Preferably, the bottom baffle is connected with the front baffle and the side baffles in a sealing manner; more preferably, the sealing is performed by using an adhesive.
