[0002] When a seaplane is performing a surface rescue mission and the aircraft is staying on the water in the mission area, the aircraft will drop the lifeboat it carries into the water to quickly approach and salvage the rescued people. When returning to the aircraft in the lifeboat, due to the action of surface waves or the slow running of the aircraft, it is difficult for the lifeboat to stay close to the rescue door of the aircraft and stay stable, making it difficult to board the people.
[0003] Therefore, it is particularly necessary to set a mooring device for the lifeboat on the outside of the aircraft. When the lifeboat approaches the aircraft, the rope on the lifeboat is wrapped around and fixed to the mooring device to ensure that the lifeboat is stably docked at the door of the aircraft rescue cabin so that personnel can quickly board the aircraft.
