An emergency lifting buoy device

Abstract

The invention relates to an emergency lifting buoyage device. The emergency lifting buoyage device comprises a pressureproof shell, surrounding slots are extended from the top of the pressureproof shell, cable frames are installed in the surrounding slots in an embedded mode, the cable frames are of a cylinder structure, lifting points are on a pressure shell platform located at the bottoms of the cable frames, the lifting points are connected with one ends of cables, and the cables are arranged in a stacked and rolled mode upward the lifting points sequentially. Buoyancy blocks are arranged at the upper portions of the cable frames, the cables are pressed by the buoyancy blocks, the buoyancy blocks are of a circular truncated cone-shaped structure, embedded parts are connected to the upper portions of the buoyancy blocks through threads, the tops of the embedded parts are provided with lifting bolts, penetrating through holes are formed in the middle portions of the buoyancy blocks, and the other ends of the cables are connected with the lifting bolts after penetrating the penetrating through holes. A plurality of locking oil cylinders used for fixing the buoyancy blocks are uniformly installed at the outer circumferences located at the upper portions of the cable frames at interval. The periphery of the top portions of the cable frames are upper decks, and the upper top faces of the cable frames and the upper top faces of the buoyancy blocks are flush with the upper decks. Application for all the sea depth can be satisfied, the use is convenient and flexible, and the operation is reliable.

Description

technical field [0001] The invention relates to the technical field of emergency devices for submersibles, in particular to an emergency lifting buoy device used when a submersible loses power underwater, which can not only mark the position of the submersible, but also realize emergency lifting, and is suitable for various deep sea applications emergency device. Background technique [0002] The emergency buoy device is the key equipment in the deep sea submersible, and its function is to mark the specific position of the submersible. In the prior art, the sealing form of the submarine emergency buoy device is manually pierced through the cabin, which cannot be applied to large depths. The device is connected to the hull by a floating ball and a cable. When the submarine is underwater, the floating ball floats on the surface of the seawater and can only mark the position of the hull, but cannot realize emergency lifting and rescue.
