Example two:
in order to block seawater entering any crevasses, the problem of inaccurate leaking stoppage is solved, the blocking efficiency is improved, and the rescue time is prolonged. A plurality of air bag devices of the embodiment are combined to form a set of seawater retarding system. The seawater retarding system is composed of at least two air bag devices, seawater detection systems are arranged on the front side and the rear side of the last group of air bag devices, and the seawater detection systems are respectively positioned in different spaces when the air bag devices are unfolded; the last air bag component is not provided with a water through hole, and the rest air bag components are provided with water through holes.
Specifically, as shown in fig. 5 to 6, three sets of airbag devices are used, a primary water passage hole 4-5 is provided in the airbag of the first set of airbag module 4, and a secondary water passage hole 4-6 is provided in the airbag of the second set of airbag module 4. Each group is provided with an air bag 4-3 in the left wall and the right wall of the cabin respectively, and the connecting line of the left air bag and the right air bag is vertical to the cabin wall. When the cabin is not filled with water, the air bags 4-3 are stored in the air bag storage devices 4-2, and after the cabin is filled with water to a certain amount, the seawater detection system 1 of each group judges whether to transmit an inflation signal; each group of corresponding inflation devices 3 receives the inflation signal, and starts to inflate a group of bilaterally symmetrical airbags 4-3 simultaneously, and the bilaterally symmetrical airbags 4-3 are contacted and extruded with each other after the inflation is finished, so that seawater is prevented from entering the next space of the cabin, and a large amount of time is won for the tasks of evacuation of people, material transportation and rescue. If too much seawater enters the cabin, which causes the first group of air bag equipment to bear too much water pressure, the seawater can enter the next space of the cabin through the first-stage water through hole 4-5 on the air bag component 4, so that the air bag component 4 is ensured not to be flushed away due to the too much water pressure, and the leaking stoppage effect is not influenced. Similarly, if the second group of airbag devices bears excessive water pressure, seawater can enter the next space of the cabin through the secondary water through holes 4-6 on the airbag module 4, so as to ensure that the airbag module 4 cannot be flushed away due to the excessive water pressure, and the leaking stoppage effect is not affected. In order to prevent the seawater entering the chamber from entering other positions of the ship, the third group of air bag assemblies are not provided with through holes. Simultaneously all set up a sea water detecting system 1 in the side around the third group gasbag subassembly, when the gasbag subassembly of third group launches, two sea water detecting systems 1 are separated by the gasbag subassembly of third group, are located the space of difference. When the last seawater detection system 1 judges that the detection module is submerged for a time exceeding a threshold value, the signal generation module 1-2 of the last seawater detection system 1 generates a signal and transmits the signal to all the inflators 3, and the inflators 3 start to inflate the corresponding airbag assemblies 4 after receiving the signal.
Example three:
the invention also provides a using method of the airbag device, which corresponds to the airbag device in the first embodiment. As shown in fig. 7, the specific steps include: each group of the airbag modules 4 is symmetrically arranged on a wall of a space, and a connecting line of the two airbag modules 4 is vertical to the wall; the detection module 1-1 detects the seawater entering the space, and judges whether the submerging time of the detection module 1-1 exceeds a threshold (preferably, the threshold is set to be five seconds); if the inundation time exceeds a threshold value; the signal generating module 1-2 generates a signal and transmits the signal to the inflator 3; if the inflator 3 receives the signal, the inflator 3 starts to inflate the airbag module 4, and the support module 4-4 in the airbag module 4 starts to deploy until the support module 4-4 is fully deployed, and the airbag 4-3 in the airbag module 4 is fully butted left and right, and the inflation is stopped.
Corresponding to the seawater retarding system in the second embodiment, the invention also provides a using method of the seawater retarding system. As shown in fig. 8-10, the details are as follows: after the cabin enters the seawater, the seawater enters the first group of detection modules 1-1 through the straight notches 1-3, the seawater detectors 1-4 measure the time of the seawater detection system submerged by the seawater, and judge whether the detection module detects that the submerged time exceeds a threshold value (preferably the threshold value is set to be five seconds), and accordingly judge whether the first group of airbag equipment needs to be started. If the first group of airbag equipment does not need to be started, the system does not react, and the time of the seawater detector submerged by the seawater is continuously monitored; if the first group of airbag devices need to be started, a signal is generated by the signal generation module and transmitted to the communication cable 2, after the communication cable is transmitted to the first group of inflating devices 3, the inflating devices 3 start to inflate the first group of airbag assemblies 4, meanwhile, the scissor-type support structures 4-4 in the first group of airbag assemblies 4 start to be unfolded, finally, the scissor-type support structures 4-4 corresponding to the upper part and the lower part are completely unfolded and butted together, and the left airbag 4-3 and the right airbag 4-3 are also extruded together to prevent seawater from entering the second space of the cabin. If the seawater is excessive, the seawater enters a second space of the cabin through the primary limber hole 4-5, the seawater detector 1-4 in the detection module 1-1 of the second group measures the time of the seawater detection system submerged by the seawater, whether the detection time of the detection module submerged exceeds a threshold value (preferably, the threshold value is set to be five seconds) is judged, and if the signal generation 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 generating module 1-2 judges that the second group of airbag equipment needs to be started, a signal is generated and transmitted to the second group of inflating device 3 through the communication cable 2, the inflating device 3 inflates the second group of airbag assembly 4, meanwhile, the scissor-type supporting structures 4-4 in the airbag assembly begin to unfold, finally, the left scissor-type structure 4 and the right scissor-type structure 4 are in butt joint, the airbags 4-3 are also squeezed mutually, and seawater is prevented from entering a third space of the cabin. If seawater still enters the third space through the secondary limber holes 4-6, the third group of air bags repeats the steps until the ship overturn-preventing symmetrical air bag assembly 4 is completely opened.
As a further improvement of the technical solution of the method for using the seawater retarding system, the specific flow is shown in fig. 11: when seawater enters the detection module 1-1 of the fourth seawater detection system, the seawater detector 1-4 can measure the time of the seawater detection system submerged by the seawater. If the signal generation module 1-2 judges that all airbag devices do not need to be started, the system does not react; if the signal generation module 1-2 judges that the seawater detection system is submerged by seawater for at least five seconds and all the air bags need to be opened, the seawater pressure is over high, so that the front air bags are flushed by the water pressure, the seawater enters other spaces of the cabin, or the front air bags are not opened due to measurement or judgment errors of the detection module. The signal generating module 1-2 of the fourth seawater detection system generates a signal and transmits the signal to the three front groups of air charging devices 3 through the communication cable 2, the air charging devices 3 simultaneously charge the corresponding air bag assemblies 4, the scissor-type support structures 4-4 in the three groups of air bag assemblies 4 are also unfolded simultaneously to provide mechanical support for the air bags 4-3, finally, all the scissor-type support structures 4-4 are completely butted, and the air bag assemblies 4 are also all extruded together to prevent seawater from entering the rest space of the cabin or other areas of the ship. So far, the whole air bag opening process is finished.
