Background

The engineering operation of salvaging objects sunk in water comprises salvaging ships, aircrafts, goods, marine product collection, underwater scientific investigation, underwater sampling and the like. The sea-going ship enters the cabin due to various reasons, so that the ship is submerged due to insufficient buoyancy. There are many methods for fishing, and the following are commonly used: the salvage ship is matched with a crane and a steel cable salvage method, a buoyancy salvage method, a buoy salvage method and the like. In the crane and steel cable salvage method, a salvage ship is large in size relative to a salvage target, and the requirements on manpower and material resources and the salvage cost are high. The specific process of the buoyancy salvage method is as follows: the method comprises the steps of firstly putting silt on a ship, then tying one end of a rope on the ship, tying the other end of the rope on the ship to be salvaged, throwing the silt out of the ship, lightening the quality of the ship, and floating up under the buoyancy action of water, so that a sunken ship floats up and can be dragged away. The conventional salvage method of the sunken ship is a buoy salvage method, namely, a plurality of buoys float out of the water surface by virtue of buoyancy after being inflated underwater. The operating principle of the float fishing method is that water is filled in the barrel when the float is installed, compressed air is filled in the float after the float is installed around the sunken ship, water in the float is discharged, and the sunken ship floats out of the water surface under the buoyancy effect of the float because the gravity of the float is reduced. The method comprises the following steps that a diver enters water, the floating pontoon and the sunken ship are bolted through a steel cable, then, the air compressor on the salvage ship is started, air is pressed into the floating pontoon, seawater in the floating pontoon is emptied, and the sunken ship floats out of the water surface through buoyancy generated by the salvage pontoon. Although the buoyancy of water generated by the float fishing method is large and reliable, and the construction is convenient and safe, the fishing method has the following defects:

1. an inflation device and a salvage ship for bearing the inflation device are required to be independently arranged, so that the construction cost is high, and the transportation and carrying are inconvenient;

2. when the buoy is used, water needs to be filled in, and the buoy needs to be manually installed on a sunken ship, so that time and labor are consumed, and the working efficiency is low;

3. the flotation pontoon self volume is unchangeable, if need adjust sunken ship rising speed among the salvage process, only can increase and decrease flotation pontoon quantity, and this needs many people of diver or the dismouting of launching many times, and the process is loaded down with trivial details, efficient, and more importantly, the operation of launching, especially deep water district, with high costs and have great potential safety hazard.
