Description

Release equipment for ship lifeboat

Technical Field

The invention relates to the technical field of marine equipment, in particular to release equipment for a ship lifeboat.

Background

A marine lifeboat is a type of rescue equipment specifically designed for evacuation of passengers and crews from a ship in an emergency situation. They are typically self-contained small vessels that can be independently maneuvered and operated on the sea or other body of water, providing for safe evacuation in the event of a water risk or emergency.

The current ship lifeboats need to be equipped with release devices to be used normally on the ship body, and the current ship lifeboat release devices are provided with a suspension type and a free-falling type. The suspended lifeboat release device is characterized in that the lifeboat is suspended outside a ship body through a plurality of ropes of a crane, when the suspended lifeboat release device is used, the lifeboat can be escaped from the lower part of the lifeboat to the water surface through the crane only by logging in the lifeboat through a platform, the falling speed of the suspended lifeboat release device is controlled through the crane, the falling position is close to the ship body, the suspended lifeboat release device is easily affected by shaking of the ship body due to accidents, and the ship body collision accidents occur. The free-falling type life-boat releasing equipment is characterized in that an inclined track frame is additionally arranged on a boat body, the head of the life-boat is downwards placed on the track frame, when the life-boat releasing equipment is used, people in the life-boat are extremely easy to be damaged by impact force and boat movement, and the controllability is poor.

In order to solve the problems, we propose a release device for a ship lifeboat.
