Deep sea automatic jettison type buoyancy adjusting tank

Abstract

The application relates to a deep-sea automatic load-dumping type buoyancy adjusting water tank, which comprises a water tank for adjusting buoyancy, a first through hole and at least one arc-shaped hole communicated with the first through hole arranged at the top of the water tank; a rotary sealing rod arranged in the first through hole, an arc-shaped stopper matched with the arc-shaped hole arranged at the bottom of the rotary sealing rod; and a load-dumping device arranged in the water tank, which drives the arc-shaped stopper of the rotary sealing rod to rotate when the water tank is damaged and filled with seawater, so that the arc-shaped stopper rotates below the arc-shaped hole, the rotary sealing rod is unlocked with the water tank, and the water tank is separated under the action of gravity to reduce the load. When the buoyancy adjusting valve group is damaged, the water tank is filled with seawater, the seawater flows into a water cylinder from a second through hole, the seawater pushes a piston rod to move to one side of a driving assembly, the driving assembly drives a rotating assembly to rotate, the arc-shaped stopper is driven to rotate, the rotary sealing rod and the water tank are in the unlocked state, the water tank is separated under the action of gravity, and the load of a submarine is reduced.
