The upper discharge air bag is a device used for the discharge of the ship when it is launched and sunk. It is usually made of rubber or synthetic rubber and has the characteristics of high pressure resistance, high wear resistance and anti-aging. In the case of ship repair, maintenance, rescue and so on, the updrain water bag is widely used in the sinking and removal of ships.

The working principle of the air bag on the ship is to use the air pressure difference to discharge the gas inside the air bag, so that a certain pressure is generated outside the air bag, and the ship is lifted or towed away. Compared with the traditional fixed devices such as wire rope and chain, the upper drainage air bag has the advantages of simple operation, safety and reliability, and wide application range.

In terms of ship repair and maintenance, the updrain water bag can be used for launching and sinking and removing the ship. When the ship needs to be removed, the airbag can be placed under the ship, inflated to lift the ship, and then moved to the designated position. During the maintenance of the ship, the hull can be lifted by the upper discharge air bag, which is convenient for maintenance personnel to repair and replace parts.

In terms of ship rescue, the updrain water bag can be used for the rescue of flooded ships. When a ship is flooded, the hull can be lifted using an updrain airbag and then towed to a safe position. At the same time, the upper discharge water bag can also be used for the rescue of trapped people, passing the air bag to the trapped people to help them escape.

In short, the airbag is an important equipment for ship repair, maintenance and rescue, which has a wide range of application prospects and market prospects. With the continuous development and application of science and technology, it is believed that there will be more new ship equipment and technology in the future, bringing more opportunities and challenges to the development of the ship industry.
