The invention discloses a gravity unhooking device for underwater air bag buoyancy salvage. The gravity unhooking device comprises a lifting lug base, wherein pin holes are formed in two clamping plates, pin shafts capable of transversely penetrating through hook containing grooves movably penetrate through the pin holes, a cylinder barrel is connected to the left side of a mounting disc, a pistonis arranged in the cylinder barrel, the left ends of the pin shafts penetrate through the through holes, extend into the cylinder barrel and are connected with the center of the right end face of thepiston, an annular oil inlet groove is formed in the outer circumferential face of the right end of the piston, and a compression spring is arranged between the left end face of the piston and the left end face in the cylinder barrel. The unhooking device has the beneficial effects that the unhooking device is particularly suitable for underwater unhooking and can also be used on land, locking ofthe state of the plug pin can be guaranteed, accidental underwater unhooking action is prevented, unhooking devices of different cylinder diameters and pin shaft size series can be designed, and thestructural expansibility of the unhooking device is good.
