Background
At present, a net sleeve is generally arranged outside a rubber pontoon cylinder body, and a binding sling is used as a hanging point so as to connect a salvaged object; the net sleeve is matched with the cylinder, the design is that the reference cylinder is completely filled to the rated pressure working state, the net sleeve and the cylinder are completely matched, but in the actual underwater use inflation process, buoyancy and pressure are gradually formed from the start of inflation, and the phenomenon that part of the cylinder is separated from the net due to the fact that the net density of the net sleeve is too small often occurs, so that the cylinder is separated from the net sleeve; the prior method is to increase the grid density and prevent the barrel from falling off, and plays a role in fixing the barrel to a certain extent in practice, but the barrel and the net sleeve still cannot be closely connected together, and the risk of net sleeve fracture caused by uneven stress and balance state still exists, so that the buoyancy transmission mode of the pontoon needs to be further improved;
the length of the current rubber pontoon is very long, and some rubber pontoons even reach 30 meters, and the air charging holes can only carry out air charging and discharging control from air nozzles at two ends. In the actual underwater inflation process, because the gas is inflated from the gas nozzle of one section, buoyancy is necessarily formed at the ball heads at the two ends, so that the two ends are lifted, and the gas is slowly transited to the middle of the cylinder after the ball heads at the two ends are inflated to a certain degree. Because the difference of barrel levelness leads to the flotation pontoon slope, then can lead to the gas that fills from both ends to gather to highly higher end gradually, thereby lead to the flotation pontoon to incline more, the buoyancy that the stress point that connects born can be bigger, the net cover is at high end tie point atress increase gradually this moment, when exceeding intensity, the net cover breaks and leads to the flotation pontoon to break away from in the net cover, the flotation pontoon then rises to the surface of water fast, the in-process that rises, inside atmospheric pressure increases gradually, if the pressure release of no relief valve or pressure release volume are too little, thereby lead to the flotation pontoon internal pressure to rise to exceeding the burst pressure, the flotation pontoon bursts at the surface of water, the energy of its blasting is huge, the casualties loss of property that causes will be very huge. The current solution is realized by adding more net sleeve hanging points, improving the blasting safety coefficient of the pontoon, and the like, which all lead to a great increase in the pontoon cost. Therefore, the underwater attitude of the pontoon in the inflation process is stable, the balance of each stressed connection point is realized, and the method is very important for meeting the use performance and ensuring the use safety.
