The limiting plate 207 rotates to a vertical state, and the micro water pump 213 pumps out the river water in the fixing sleeve 202. The return spring 214 will drive the piston plate 203 and the fixing rod 204 to move outwards. The fixing rod 204 moving outwards will make the limiting plate 207 close to the inner wall of the sunken ship, and the limiting plate 207 will clamp the fixing rod 204, thereby fixing the fixing sleeve 202 and the salvage airbag 1 on the sunken ship's bulkhead;

[0040] Repeat the above process, install multiple groups of salvage airbags 1 one by one on the bulkhead of the sunken ship, and inject air into the salvage airbags 1 through the air injection pipe and the air inlet pipe 403. The air entering the salvage airbags 1 will increase the buoyancy of the sunken ship, and the sunken ship will gradually float up under the action of the buoyancy.
