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.

    一种水下气囊浮力打捞的重力脱钩装置,包括吊耳座,两个夹板上均设置有销孔,销孔内活动穿有可横向贯穿挂钩容纳槽的销轴,安装盘左侧连接有缸筒体,缸筒体内设置有活塞,销轴左端穿过通孔延伸入缸筒体内并与活塞右端面中心相连接,活塞右端端部外圆周面上开有圆环形的进油槽,活塞左侧端面与缸筒体内左侧端面之间设置有压缩弹簧。本发明的有益效果是:本发明特别适用于水下脱钩,陆地也能使用,能保证插销状态的锁紧,防止水下意外脱钩动作,可设计不同缸径和销轴尺寸系列的脱钩装置,产品结构扩展性好。
