Ship body back-off rescue equipment

Abstract

The invention belongs to the field of ship body back-off rescue equipment, and particularly relates to ship body back-off rescue equipment which comprises a machine body; wherein a lifting rescue component is arranged in the center of the interior of the machine body, an inflation pressure maintaining component is arranged at the position, located on one side of the lifting rescue component, in the machine body, and a welding gun forcible entry component is arranged at the bottom of the inner side of the machine body; a grinding fixing part is arranged on the outer side of the bottom of the machine body, a sealing head slidably sleeves the end face of the side, away from the lifting rescue part, of the bottom of the machine body, and a sealing door is arranged on the side wall of the machine body. By means of the equipment, operations such as grinding, fixing and pressure-maintaining forcible entry can be carried out on the bottom of the inverted ship so that trapped persons can be rescued.

Description

technical field [0001] The invention belongs to the field of hull undercut rescue equipment, in particular to a hull undercut rescue equipment. Background technique [0002] When a ship capsizes, the speed of the capsize is fast, and the air in the cabin will form an air cushion near the bottom of the ship. The crew and passengers who did not escape the shipwreck in time are likely to be trapped in the air cushion and survive. Dangerous factors such as hypoxia and changes in ship attitude are always threatening the lives of trapped people. [0003] For this kind of rescue, there are two commonly used rescue methods at present. One is that divers enter the inverted boat from underwater to rescue. This method is subject to many limiting factors: 1. The meteorological and hydrological conditions on site must meet the requirements of divers ; 2. Underwater visibility is generally very low, and divers can only touch by hand, and work efficiency is low; 3. Floating objects and sh...

[0003] For this kind of rescue, there are two commonly used rescue methods at present. One is that divers enter the inverted boat from underwater to rescue. This method is subject to many limiting factors: 1. The meteorological and hydrological conditions on site must meet the requirements of divers ;2. Underwater visibility is generally very low, and divers can only touch by hand, which results in low work efficiency; 3. Floating objects and sharp objects underwater may pose a life threat to divers

[0004] Another rescue method is to first determine the approximate location of the trapped person, and then cut a hole in the bottom plate of the ship to rescue the trapped person through the hole. This method has relatively lower requirements on the site environment, and the safety of the rescuer is also easier to guarantee. , but the air in the air cushion will escape quickly after the hole is opened, which may further aggravate the attitude change of the buckled ship and threaten the lives of the trapped people
