The application method of the anti-pinch air flotation tank device with automatic liquid level adjustment specifically comprises the following steps:

1) placing the track buckle 3 on the box body 1 into the support frame 4 corresponding to the support track square hole 5;

2) connecting the bracket rope connection 7 with the buoyancy tank rope connection 2 by using a steel rope 9;

3) and (3) debugging on the ground, enabling the box body (1) to slide smoothly in the support frame (4) and then to be put into the pool, adjusting the support frame (4) to be placed on the bottom surface of the water outlet weir in parallel, and connecting the support frame (4) with the pool wall by using a fixing piece (8).

4) After the box body 1 and the support frame 4 are installed, the buoyancy of the buoyancy tank is F_{Floating body}Gravity G of the buoyancy tank_FromBuoyancy tank adding counterweight force G_{Fitting for mixing}Pipeline vacuum suction F_{Suction device}Steel cable tension F_{Pulling device}Automatically reciprocate up and down along the track under the action of the floating box, so that the height of the floating box is automatically adjusted.

The up-and-down motion of the buoyancy tank in the step 4) is mainly influenced by the buoyancy F of water_{Floating body}Gravity G of the buoyancy tank_FromBuoyancy tank adding counterweight force G_{Fitting for mixing}Pipeline vacuum suction F_{Suction device}Steel cable tension F_{Pulling device}Multiphase dynamic force balance effect carries out periodic motion in cycles between highest and minimum water seal liquid level, makes flotation tank automatically regulated height, forms a certain amount of water seal above sedimentation tank inlet pipeline to prevent that gas from leading to the water to dissolve gas, press from both sides gas entering sedimentation tank because rivers suction negative pressure effect, highest, minimum water seal liquid level control satisfies as follows:

1. highest water seal liquid level h_{Height of}

When the liquid level of the water tank reaches the highest water seal liquid level h_{Height of}When the buoyancy tank begins to float under the action of buoyancy, i.e. F_{Floating body}>F_{Suction device}+G_From+G_{Fitting for mixing}The specific decomposition is calculated as:

note: p: is at standard atmospheric pressure; the size of the buoyancy tank is as follows: length L, width A; s, the area of a water outlet pipe opening; rho_{Liquid for treating urinary tract infection}: the density of the water.

At the moment, the floating box floats upwards to cause the distance between the floating box and the water outlet pipe mouth to be enlarged, the water outlet flow is increased, the corresponding water seal level is reduced until the water seal level is reduced to h_{Is low in}Stop, i.e. pipe vacuum suction F_{Suction device}Increased force and tension F of the steel cable_{Pulling device}The balance is restored under the action of the resultant force.

2. Minimum water seal liquid level h_{Is low in}

When the liquid level of the water tank is reduced to the lowest water seal liquid level h_{Is low in}In time, the vacuum suction force F of the water tank pipeline_{Suction device}Far greater than F_{Floating body}I.e. F_{Floating body}<F_{Suction device}+G_From+G_{Fitting for mixing}However, because the floating box is provided with the steel cable limiting function, the final floating box is maintained at the lowest water seal liquid level h_{Is low in}Unchanged, namely:

F_{floating body}+F_{Pulling device}＝F_{Suction device}+G_From+G_{Fitting for mixing}

At the moment, because the distance between the floating box and the water outlet pipe mouth is minimum, the water outlet flow is reduced, the corresponding water seal water level rises until the water seal liquid level rises to h_{Height of}Stopping, i.e. buoyancy F of the buoyancy tank increases, when F_{Floating body}>F_{Suction device}+G_From+G_{Fitting for mixing}The buoyancy tank begins to float upwards.

The length of the steel cable is the lowest water seal liquid level h of the buoyancy tank_{Is low in}At the moment, the buoyancy tank is tensioned by the cable to maintain its distance from the bottom of the tank at H₂In practice H₂Can be adjusted according to the requirement of the lowest water seal liquid level.

The maximum counterweight of the buoyancy tank is controlled by the highest water seal liquid level h_{Height of}Determining that the highest water seal liquid level is required to be higher and heavier corresponding to the counterweight, the buoyancy tank starts to float when exceeding the highest water seal liquid level, but the highest water seal liquid level cannot submerge the buoyancy tank, so the maximum counterweight can be calculated by the following formula:

h_{height of}＝H₁+H₂

Note: h₁Indicating the height of the buoyancy tank; h₂Indicating that the buoyancy tank is at the lowest water seal level h_{Is low in}The height of the floating box from the bottom of the pool.

The minimum counter weight of the buoyancy tank is the self weight of the buoyancy tank.
