The invention relates to rescue equipment for sunk ships, in particular to a compressed airbag for sunk ship rescue. The compressed airbag mainly comprises an airbag, a compressed air cylinder, an electromagnetic valve, an electromagnetic coil housing, an electromagnetic coil and a conductor group. While in use, the compressed airbag provided by the invention in a non-use state is released in water along the surface of a sunk ferromagnetic ship body. Under the control of the conductor group, voltage is applied to the electromagnetic coil to generate an electromagnetic field so that the compressed airbag is adsorbed to the ship body by means of magnetic force. Under the control of the conductor group, the electromagnetic valve is opened to release the compressed air cylinder in an inflating chamber; and increasing buoyancy is generated in the inflating process of the inflating chamber. Multiple compressed airbags for sunk ship rescue, provided by the invention, work together to increase the buoyancy applied to the sunk ship. The compressed airbag for sunk ship rescue, provided by the invention, has the advantages of simple structure and convenience in storage and is capable of rapidly implementing rescue in case of absence of divers on site or unknown underwater environment.
