Description

Hydrostatic pressure releaser for inflatable life raft

Technical Field

The invention relates to the technical field of underwater salvage equipment, in particular to a hydrostatic pressure releaser for an inflatable life raft.

Background

An inflatable life raft is a life-saving device for persons in distress when a marine accident happens, when the life raft is used, the life raft is dropped from the outboard of the ship, at the moment, the life raft is inflated and formed by CO2+ N2 mixed gas which is equipped by the life raft, and floats on the water surface, when the normal sinking speed of the ship is very high and manual release is not available, the life raft stored on a raft frame sinks along with the ship, when the life raft sinks to 2-4m away from the water surface, a hydrostatic pressure releaser automatically loosens a life-saving binding rope due to the pressure of water, so that the life raft freely floats out of the water surface, as the ship continues to sink, a first cable rope is continuously pulled out from a storage cylinder by virtue of the buoyancy of the life raft storage cylinder until a quick release valve is opened, the life raft is inflated and formed, and when the ship continues to sink, the easy-breaking rope is pulled off, the life raft is separated from the sunken ship, floats on the water surface, and the persons in distress can ride, on the ship and in personnel can step into the raft in falling into the water obtain rescue, nevertheless the hydrostatic pressure releaser who uses at present has some not enoughly, as follows:

hydrostatic pressure releaser passes through the locking of ligature to the life raft flotation pontoon, it is placed on the sea ship, the sea ship drives hydrostatic pressure releaser and ligature rocks in the driving process, the friction rocks between ligature and flotation pontoon and the releaser, in addition the influence of sea water and external environment, strengthen the erosion to ligature and hydrostatic pressure releaser, lead to ligature wearing and tearing fracture and hydrostatic pressure releaser to damage, make the flotation pontoon drop suddenly, the life raft is automatic under the accident to be expanded, extravagant navigation resource, and hydrostatic pressure releaser damages, when making meet the marine perils, the unable timely release of flotation pontoon, lead to life raft release untimely, influence rescue efficiency.

After the life raft is opened, if the bottoms of some life rafts face upwards, people are required to turn over, but certain skill and proficiency are required in the operation process, the operation in the process is undoubtedly huge when a disaster occurs, and if the life raft cannot be turned over, the use of the life raft is influenced, and the rescue difficulty is increased.
