Anti-tilt slow sinking system for ship

The overturn-preventing and sinking-slowing system for ship includes signal generating system, control system, air bag system and locking mechanism. The air bag system set on two sides of hull consists of air bag holding pressurized air and casing closed with the locking mechanism; the locking mechanism is controlled with the control system; and the control system is controlled with the signal generating system. In the ship is to overturn, the signal system sends signal, the control system unlocks the locking mechanism, the air bag casing is opened by the inner pressure and the air bags expand fast to form large air bags on two sides of the hull. The huge buoyancy of large air bags counteracts the inclining force of the hull to correct the hull and prevent overturn. During the sinking, the large air bags can retard the sinking of the ship and increase the time for the passengers to escape.
