Abstract

The invention discloses a ship lifeboat releasing device. The ship lifeboat releasing device comprises a plurality of solid rockets symmetrically arranged on the two sides of a lifeboat, a rocket launcher for containing solid rockets and a launcher base, wherein the launcher base is arranged at the bottom of the rocket launcher and is fixed on a ship deck; an ejection system is arranged in the launcher base, and consists of four parts of a gas storage tank, a gas distribution pipeline, a buffer chamber and a nozzle, wherein the gas storage tank is used for pre-storing high-pressure compressedair; the buffer chamber is communicated with the gas storage tank through a gas distribution pipeline; the nozzle is in horn shape, and is provided with a small-caliber end communicated with the buffer chamber and a large-caliber end penetrating out of the launcher base. According to the ship lifeboat releasing device, boat davit related mechanisms of a conventional lifeboat are omitted, a solid rocket ejection type full-closed lifeboat is adopted, it is guaranteed that the lifeboat can be timely separated from a ship body in a free falling mode under any deformation or damage condition of theship body; and meanwhile, the impact force caused by the free falling is relieved through the buffer action of the solid rockets.

Description

technical field [0001] The invention relates to a release device for a lifeboat, in particular to a release device for a fully enclosed lifeboat, which belongs to the technical field of ship devices. Background technique [0002] The lifeboat is a relatively effective tool for rescue and rescue of the crew when the ship is in a shipwreck. While carrying the rated crew, the lifeboat is also equipped with certain accessories, and is a rigid boat that can sail or drift in bad weather, so that the life safety of the crew and passengers is guaranteed to the greatest extent. The fully enclosed lifeboat has safe and reliable functions such as convenient crew entry and exit, good water tightness and heat insulation inside the boat. Primary lifesaving equipment. [0003] The release methods of the fully enclosed lifeboat mainly include unmooring release of the boat cable and free fall into the water. [0004] The release method of the boat cable unmooring requires that the disenga...
