Concentric double-ball lifeboat

Abstract

The invention relates to a concentric double-ball lifeboat which comprises an outer ball and an inner ball. The inner ball is arranged in the outer ball, the outer ball and the inner ball are concentric, power devices are arranged on the outer ball, a sandwich layer space is arranged between the outer ball and the inner ball, the inner ball comprises a shell and a cavity, and the cavity of the inner ball is arranged in the shell and is communicated with spaces outside the concentric double-ball lifeboat via an access passage in the sandwich layer space. The concentric double-ball lifeboat has the advantages that escape persons can be positioned in the cavity of the inner ball of the concentric double-ball lifeboat, external disturbance can be prevented from being transmitted into the inner ball via the outer ball when the concentric double-ball lifeboat shakes in intense wind and wave environments, and accordingly the concentric double-ball lifeboat is excellent in inherent wind and wave resistance; the concentric double-ball lifeboat can be in a water surface working mode and a submergence working mode; the concentric double-ball lifeboat in the submergence working mode can effective adapt to surviving in offshore fire and explosion scenes as compared with existing totally enclosed type lifeboats, can effectively avoid high-temperature and harmful gas during sea surface oil gas fire and can assist the escape persons to escape from the fire scenes from the optimal directions when the submergence depths of the concentric double-ball lifeboat exceeds the draft of the concentric double-ball lifeboat.

Description

technical field [0001] The invention relates to the technical field of water rescue equipment, in particular to a concentric double-ball lifeboat. Background technique [0002] With the rapid development of the ocean shipping industry, the global ship demand market is huge. According to the SOLAS Convention, every ship is mandatory to be equipped with a lifeboat of a certain specification. The lifeboat is very important to ensure the safety of the people on board in an emergency. However, most of the current lifeboats are poor in wind and wave resistance. In severe sea conditions, strong wind and waves can easily cause the lifeboat to roll or even capsize, thereby posing a greater threat to the lives of people in distress. Contents of the invention [0003] In order to overcome the above deficiencies in the prior art, the present invention provides a concentric double-ball lifeboat capable of effectively resisting wind and waves. [0004] In order to solve the problems o...
