Application method for cutting hole in airtight chamber of upturned ship

Abstract

The invention relates to an application method for cutting a hole in an airtight chamber of an upturned ship. The method comprises the following steps of 1) sealing the bottom surface of a sealed chamber body through a sealing component and fixing the sealing chamber body at the bottom of the upturned ship; 2) exerting a cutting personnel to open an outer sealing door, enter a transitional chamber, close the outer sealing door, open an inner sealing door, enter a working chamber and close an inner sealing door; charging gas into the working chamber through an airtight mouth to supercharge the working chamber; performing leakage detection and leakage prevention on the working chamber after the working chamber is supercharged; and then cutting a hole in the bottom of the upturned ship through cutting equipment; and 3) after the hole is cut, exerting the cutting personnel to enter the transitional chamber, close the inner sealing door and walk out of the sealed chamber body; exerting divers carrying oxygen cylinders to enter the transitional chamber, close the outer sealing door, enter the working chamber, close the inner sealing door and enter the interior of the upturned ship from the hole so as to carry out rescue work. As rescuers carry out hole-cutting and rescue works under a sealed environment provided by the airtight chamber, the operation is safe, the efficiency is high and rescue time is saved.

Description

technical field [0001] The invention relates to a method for using emergency rescue equipment on water, in particular to a method for using an airtight cabin with holes in an inverted ship. Background technique [0002] Due to bad weather and mishandling, sometimes the tragedy of the hull buckling occurs on large ships. At this time, divers need to dive into the bottom and enter the hull to observe the signs of life and rescue conditions inside the ship, and then take corresponding rescue plans according to the specific conditions obtained. . Divers dive deep, take a long time, have low visibility, and encounter various obstacles and floating objects such as cabins and aquatic plants. The safety factor is low and the efficiency of obtaining information is low, which seriously threatens the lives of divers and rescuers. Safety. If holes are directly drilled at the bottom of the undercut hull, not only will the gas inside the undercut hull leak out, but also flooding or wate...

AI Technical Summary

Problems solved by technology

When divers dive deep, the time is long, the visibility is low, and they will encounter various obstacles and floating objects such as cabins and aquatic plants. The safety factor is low and the efficiency of obtaining information is low, which seriously threatens the lives of divers and rescuers. Safety

If holes are directly drilled at the bottom of the undercut hull, not only will the gas inside the undercut hull leak out, but also flooding or water gushing will occur, which will not only accelerate the sinking of the hull, but also reduce the living conditions of the people to be rescued inside, so it is necessary Design an airtight cabin with an inverted ship opening to provide a sealed environment for rescuers. At the same time, it is necessary to design a complete and standardized method of use based on the airtight cabin to prevent hidden dangers caused by misuse
