After the water surface suspended matter suction head is placed into the water surface, the air release valve is closed, and the height from the water level line to the outer surface of the water surface suspended matter suction head is obtained through the following formula after being simplified by a mathematical model:
buoyancy equation of the whole water surface suspended matter suction head: mg ═ ρ g Δ V;
bernoulli's equation for air pressure at the water line of the inner barrel region: Δ p ═ ρ g Δ h;
an ideal gas state equation before and after air compression of the inner cylinder area:
(p0+Δp)*V2＝p0*V1；
height h of external water line on water surface suspended matter suction head:
in the formula: m is the integral mass of the water surface suspended matter suction head, g is the gravity acceleration, delta h is the internal and external water level difference, delta V is the volume of water discharged by the water surface suspended matter suction head (after the wall thickness is neglected, the internal and external water level difference delta h is multiplied by the diameter S of an inner cylinder area), S is the cross section area of the inner cylinder area, delta p is the pressure difference between air in an air area and the external atmosphere, p0 is the atmospheric pressure, V1 is the total volume of the inner cylinder area, V2 is the volume of the air area after the water surface suspended matter suction head enters the water, and h0 is the height.
