If the first group of air bag equipment is not required to be started, the system does not react, and the time for the seawater detector to be submerged by the seawater is continuously monitored; if the first group of air bag equipment needs to be started, a signal is generated by the signal generation module and is transmitted to the communication cable 2, after the communication cable is transmitted to the first group of air inflation device 3, the air inflation device 3 starts to inflate the first group of air bag components 4, meanwhile, the scissor type supporting structures 4-4 in the first group of air bag components 4 start to be unfolded, finally, the scissor type supporting structures 4-4 corresponding to each other up and down are completely unfolded and are butted together, and the left air bag 4-3 and the right air bag 4-3 are extruded together to prevent seawater from entering the second space of the cabin. If the seawater is too much, the seawater enters a second space of the cabin through the first-stage water through holes 4-5, the seawater detector 1-4 in the second group of detection modules 1-1 measures the submerged time of the seawater detection system, judges whether the submerged time detected by the detection modules exceeds a threshold (preferably, the threshold is set to be five seconds), and if the generation signal module 1-2 judges that the second group of air bag equipment does not need to be started, the system does not react; if the signal generation module 1-2 judges that the second group of air bag equipment needs to be started, a signal is generated and transmitted to the second group of air inflation device 3 through the communication cable 2, the air inflation device 3 starts to inflate the second group of air bag components 4, meanwhile, the scissor type supporting structures 4-4 in the air bag components start to be unfolded, finally, the left scissor type structures 4-4 and the right scissor type structures 4-4 are mutually butted, the air bags 4-3 are mutually extruded, and seawater is prevented from entering a third space of the cabin.

If the generated signal module 1-2 judges that all the air bag equipment does not need to be started, the system does not react; if the generated signal module 1-2 judges that the seawater detection system is submerged by the seawater for at least five seconds and all the air bags need to be opened, the seawater pressure is excessively high, so that the air bags in the front are flushed by the water pressure, the seawater enters the rest space of the cabin, or the corresponding air bag assemblies 4 are not opened due to measurement or judgment errors of the detection module in the front. The signal generating module 1-2 of the fourth seawater detecting system generates signals and transmits the signals to the three previous groups of inflating devices 3 through the communication cable 2, the inflating devices 3 inflate corresponding air bag assemblies 4 simultaneously, the scissor type supporting structures 4-4 in the three groups of air bag assemblies 4 are unfolded simultaneously to provide mechanical support for the air bags 4-3, finally all the scissor type supporting structures 4-4 are in butt joint, and the air bag assemblies 4 are extruded together to prevent seawater from entering the rest space of the cabin or other areas of the ship. So far the whole airbag opening process is finished.
