Description

Technical Field

[0001] The utility model relates to the technical field of unmanned lifeboats, in particular to an equipment installation and maintenance device for unmanned lifeboats. Background Art

[0002] Unmanned lifeboats are important safety equipment on ships. They are mainly used to provide survival and rescue support for passengers and crew members in emergencies at sea.

[0003] In order to ensure the convenience of equipment installation and maintenance, unmanned lifeboats are usually equipped with special equipment installation and maintenance devices on their hulls. The equipment installation and maintenance devices usually include installation and maintenance ports and are equipped with corresponding installation and maintenance covers. However, in the prior art, the installation and maintenance cover and the installation and maintenance port are usually connected together by threads. This connection method has some problems. First, the installation and maintenance cover needs to be rotated frequently during loading and unloading, which makes the operation not convenient and efficient; second, due to the limitations of threaded connections, the sealing is affected, which often leads to water seepage and leakage and damage to the equipment.
