The inflation and air exhaust rubber tube 10 connected with the wave-resistant curtain capable of controlling sinking and floating is connected to the inflation valve 8, the inflation is started, the wave-resistant curtain capable of controlling sinking and floating is floated, and the inflation valve 8 is closed for use.
(4) Pumping air and sinking. After the work is finished, the air inflation and exhaust rubber tube 10 is moved to the air exhaust valve 6, the air exhaust valve 6 and the inflation valve 8 are opened, the air is exhausted after the machine is started, the wave blocking curtain is contracted to reduce buoyancy, the wave blocking curtain is sunk to the bottom of the water, and navigation is recovered.
The working principle and the process are as follows:
the working principle of the controllable sinking and floating wave-resisting curtain for resisting and attenuating shock waves is that an air bag in the controllable sinking and floating wave-resisting curtain is utilized to generate an air wall in water, and the density rho of the air wall1Small, wave propagation velocity c1Also small, wave impedance ρ1c1About 9860kg/m2S; and density of water ρ2Greater, wave propagation velocity c2Greater wave impedance of water ρ2c2About 1450000kg/m2.s。
When the shock wave in water is incident and meets the wave-resistant curtain capable of controlling sinking and floating, the particle speeds of two sides on the interface are equal, and the ratio of the wave impedance of water to the wave impedance of the air bag gas in the wave-resistant curtain capable of controlling sinking and floating is set as follows:
n＝ρ2c2/ρ1c1ρ1c1＝147.06
the shock wave transmittance of the shock wave transmitted into the wave-blocking curtain with controllable sinking and floating is as follows:
T＝2/(1+n)＝0.0135
the reflection rate of the shock wave reflected back into the water is:
f ═ 1-n)/(1+ n) — 98.65 (reflected shock wave is opposite to incident shock wave direction).
When the peak pressure of the incident shock wave is P, the peak pressure of the shock wave transmitted into the wave-resisting curtain with controllable sinking and floating is PtThe peak pressure of the shock wave reflected back into the water is PfThe method comprises the following steps:
Pt＝T·P＝0.0135P
Pf＝F·P＝-98.65P

The wave-resisting curtain capable of controlling sinking and floating can reflect incident shock waves and absorb the energy of the incident shock waves. In the process that the air bag deforms, compresses and stretches under the action of shock wave pressure, a part of shock wave energy is converted into heat and is lost in a water medium through heat conduction.
