Inflatable-opening-closing type offshore lifesaving device

Abstract

The invention discloses an inflatable-opening-closing type offshore lifesaving device which comprises a floating airbag, a lifesaving cabin and a sealing assembly. The floating airbag is arranged at the bottom of the lifesaving cabin, and an inlet is formed in the upper end of the lifesaving cabin; an annular mounting groove is formed in the inner side of the periphery of the upper end of the lifesaving cabin; the sealing assembly comprises a connecting plate, an inflating air pump and a clamping airbag; an air flowing channel is formed in the connecting plate, and the inflating air pump is arranged at the bottom of the connecting plate; the inflating air pump is communicated with the air flowing channel, and a connecting ring groove is formed in the periphery of the connecting plate and is communicated with the air flowing channel; and the clamping airbag is of an annular structure, the inner side of the clamping airbag is fixedly communicated with the outer side of the connecting ring groove, and the clamping airbag is clamped and installed in the annular installing groove at the upper end of the lifesaving cabin. The opening and closing mode is safe.

Description

technical field [0001] The invention relates to an inflatable opening and closing type marine lifesaving device. Background technique [0002] At present, when a shipwreck occurs, people generally escape by taking a small boat on a passenger ship or by wearing a life jacket. In seawater, many passengers may be killed before the arrival of the lifeguards, so it is necessary to develop a lifesaving cabin. The current lifesaving cabin has been developed, but the opening and closing structure at the upper end of the lifesaving cabin is made of It is not ideal. Now it is generally connected to the upper end of the cabin through the connecting cover. However, due to contact with seawater or even immersion, sometimes the connecting cover and the cabin will be rusted and blocked, making it difficult to open and cause safety hazards. Therefore, the existing The opening and closing methods and safety of marine lifesaving devices are not high. Contents of the invention [0003] Aim...
