The working process of the embodiment is as follows:

under the initial condition, the buoyancy lifting plate 6 is positioned on the lower baffle plate 8, so that the lower end of the vent pipe 4 is sealed, the air pressure inside and outside the tank body 2 is the same, the flow of the water inlet 3 is greater than that of the water outlet 9, the liquid level inside the tank body 2 can gradually rise, and the air volume inside the corresponding tank body 2 can be compressed. The liquid level in the tank body 2 continuously rises until the floating plate 6 on the lower baffle plate 8 is contacted with the liquid level. Because the liquid level can not cross the floating plate 6, the weight of the floating plate 6 is large, if the flow of the water gap 3 is still larger than the flow of the water outlet 9, the floating plate 6 is not moved, the liquid level outside the vent pipe 4 continues to rise, the air in the tank body 2 is further compressed and increased in pressure intensity, so that the liquid level pressure intensity at the position of the floating plate 6 is continuously increased, the pressure of the liquid level on the floating plate 6 is larger than the sum of the atmospheric pressure above the floating plate 6, the gravity of the floating plate 6 and the maximum static friction force borne by the floating plate 6, the floating plate 6 rises, a part of the water in the corresponding tank body 2 enters the vent pipe 4, the liquid level outside the vent pipe 4 is reduced to a certain degree, and the air pressure intensity outside the vent pipe 4 is reduced to a certain degree, so that the pressure. Due to the reduction of the air pressure outside the vent pipe 4 and the influence of the self weight of the water in the vent pipe 4, the pressure of the liquid level on the buoyancy lifting plate 6 is reduced after the buoyancy lifting plate 6 rises for a certain distance, and therefore the buoyancy lifting plate 6 can stop after rising for a certain distance. If the flow of the water gap 3 is smaller than the flow of the water outlet 9, the liquid level in the tank body 2 is lowered, the water in the vent pipe 4 is reduced, the liquid level outside the compensation vent pipe 4 is reduced, and the change of the air pressure in the tank body 2 is reduced.
