Life preserver of ship lifesaving device

Abstract

The invention provides a life preserver of a ship lifesaving device and belongs to the technical field of ships. The life preserver solves the technical problem that it is difficult for a drowning person to get on a ship when an existing life preserver is used for rescuing the person. The life preserver of the ship lifesaving device comprises a framework made of a metal material, a drive cabin arranged in a sealed manner and an inflation cabin arranged in a sealed manner. The drive cabin is fixed to the rear end of the framework. The inflation cabin is fixed to the front end of the framework. An air injection bag is arranged at the portion, between the drive cabin and the inflation cabin, on the framework and made of a rubber material. An inflation pump and a water pump are fixed into the inflation cabin. An inflation opening of the inflation pump is communicated with the air injection bag through an inflation pipe. A water outlet of the water pump is communicated with the air injection bag through a water filling pipe. A one-way drainage valve is fixed to the bottom face of the air injection bag. An outlet of the one-way drainage valve is located outside the air injection bag. The air injection bag can float on the water surface when the air injection bag is filled with air and the air injection bag can sink into water when the air injection bag is filled with water. The life preserver has the beneficial effect that the drowning person can be actively rescued.

Description

technical field [0001] The invention belongs to the technical field of ships, and relates to a ship life-saving device, in particular to a life-saving device of a ship life-saving device. Background technique [0002] Ships are an important means of water transportation for human beings. The development of ships has gone through thousands of years. From canoes to sailboats to modern ships, the power and safety of ships have been greatly developed. However, due to various accidents, there will still be When the ship sinks or the crew falls into the water, life-saving devices on the ship are indispensable. [0003] At present, lifesaving devices on ships generally include lifebuoys, life rafts or wooden boats. Lifebuoys are generally hung on the railings of the hull for easy rescue. Liferafts or wooden boats are generally fixed on the hull deck; but lifesaving devices are generally seldom used. The effectiveness of rescue requires the maintenance of lifesaving devices.

[0002] Ships are an important means of water transportation for human beings. The development of ships has gone through thousands of years. From canoes to sailboats to modern ships, the power and safety of ships have been greatly developed. However, due to various accidents, there will still be In the event of the ship sinking or the crew falling into the water, life-saving devices on the ship are indispensable

[0003] At present, lifesaving devices on ships generally include lifebuoys, life rafts or wooden boats. Lifebuoys are generally hung on the railings of the hull for easy rescue. Liferafts or wooden boats are generally fixed on the deck of the hull; The effectiveness of the rescue requires the maintenance of lifesaving devices. Since the current lifebuoys, liferafts or wooden boats are placed in the open air, sea water, sea water and sunlight will cause damage to the lifebuoys, liferafts or wooden boats. The strength requirements for maintenance Larger, which increases the cost; at the same time, the current life raft or wooden boat is generally fixed at a fixed position on the hull, but it is often far away from the position of the life raft or wooden boat during rescue, and the life raft or wooden boat is unloaded and transported to The corresponding position is very time-consuming and delays the rescue; in addition, the life raft or wooden boat is extremely inconvenient when rescuing the drowning person, and it is difficult for the drowning person to climb onto the life raft or wooden boat
