Description
Technical Field
The invention belongs to the technical field of ship auxiliary equipment, and particularly relates to a hydrostatic pressure releaser for an offshore life raft.
Background
The hydrostatic pressure releaser is a free floating device (such as a life raft, a satellite emergency radio position indicating mark and the like) attached to the side surface of a ship, can be released in an automatic and manual mode when the ship sinks or needs to be released, and the internal mechanical structure of the hydrostatic pressure releaser mainly comprises a diaphragm, a spring and a blade. When water enters the chamber, the diaphragm deforms under the action of water pressure, so that the spring above the diaphragm is jacked to loosen and compress, and the blade is released to cut off the rope.
However, the existing hydrostatic pressure releaser has the following defects in the actual use process: firstly, when the depth of seawater of the existing hydrostatic pressure releaser is 1.5-4 m, the diaphragm is deformed by water pressure to drive the spring to prop up the bolt, and then the connecting rope is automatically cut off, although the working mode is sensitive, quick and efficient, the buoy for storing the life raft and the hydrostatic pressure releaser are usually installed on the two side walls of the ship, the ship is easy to generate large jolt under the action of fierce and billow waves in the process of parking on the sea surface or moving, the two sides of the ship are easy to fluctuate in the jolt and billow process, so that the hydrostatic pressure releaser arranged on the two side walls is also temporarily sunk into the water, and once the hydrostatic pressure releaser sinks into the water depth below 1.5m or is influenced by the impact of the waves, when the pressure reaches a preset value, the hydrostatic pressure releaser is easy to react quickly to generate mistaken touch, the connecting rope is cut off, and the buoy falls off, thereby causing unnecessary property loss; secondly, this hydrostatic pressure releaser needs to be installed on the hookup rope, need the hookup rope to run through the through-hole, and for the convenience to insert the hookup rope, the diameter of through-hole needs to be a bit more than the diameter of hookup rope usually, and boats and ships drive hydrostatic pressure releaser and hookup rope in the driving process and rock, the friction rocks between hookup rope and flotation pontoon and the releaser, and the long-time influence of sea water and external environment, cause the erosion to the hookup rope easily, make hookup rope and hydrostatic pressure releaser contact site wearing and tearing fracture and take place to damage, the flotation pontoon drops suddenly, the life raft is automatic to be expanded under the no accident, extravagant navigation resources.
