Description

Technical Field

[0001] The utility model relates to the technical field of inflatable rubber lifeboats, in particular to a portable automatic inflatable rubber lifeboat. Background Art

[0002] So far, maritime accidents and capsizing incidents still occur from time to time. Being able to escape as soon as possible has become the key to the survival of crew members and passengers. Therefore, many ships are equipped with a certain number of lifeboats. Many of the current lifeboats are rubber inflatable lifeboats. When not in use, the gas in the rubber boat body is emptied and it is folded and stored. In case of emergency, the rubber boat body is inflated. The traditional manual inflation method is slow and will reduce the golden time for escape. Nowadays, most of them are directly equipped with automatic inflation equipment and connected to the lifeboat inflation port. When used, it can be directly started to quickly fill the entire lifeboat, buying more precious time for escape. However, the internal air chambers of the existing inflatable structure on the lifeboat are mostly interconnected. Although it can facilitate integrated inflation, if any air chamber has a leakage problem, it will affect the whole, and then cause the entire inflatable lifeboat to shrink and sink, making the people on it in danger of drowning. The safety strength is not high enough and the risk of leakage is relatively large. Utility Model Content
