A kind of ship hull plugging device and its plugging method

Abstract

The invention provides a hull leaking stoppage device and a leaking stoppage method thereof. The leaking stoppage device comprises a locating mechanism, an air bag and an air bottle. The locating mechanism is sleeved with the air bag. The air bottle is arranged on the outer side of the air bag. The locating mechanism is provided with a main shaft, a telescopic component and a locating air channel.The locating air channel communicates with the air bottle and the air bag. The telescopic component is connected to the main shaft in a radial telescopic mode and expands outwards in the radial direction or retracts inwards in the radial direction along with rotation of the main shaft. When the telescopic component expands outwards in the radial direction, the telescopic component moves to the inner wall of a crack, and when the telescopic component retracts inwards in the radial direction, the telescopic component moves towards the main shaft. Therefore, the crack of a hull is comprehensively plugged, location is firm, operation is simple, leaking stoppage is conducted effectively and quickly, and streams are prevented from entering a cabin.

Description

technical field [0001] The invention relates to the technical field of leak plugging, in particular to a leak plugging device and a leak plugging method suitable for hull leaks. Background technique [0002] Ships or warships will encounter various emergencies during their voyage, such as accidental collisions and rock landings. For ships, there may also be dangerous situations of being hit by torpedoes. How to quickly plug the breach , which directly affects the anti-sinking performance of ships or warships. The commonly used plugging methods in the past include plugging boards, plugging pads, plugging boxes, plugging bags, plugging umbrellas, etc., by blocking the inner or outer walls of the cabin to prevent external seawater from entering the cabin. External auxiliary equipment is often required for locking and fixing. However, due to the high time requirement for plugging and the strong impact of sea water, it is necessary to quickly carry out the plugging operation, ot...

Problems solved by technology

The commonly used plugging methods in the past include plugging boards, plugging pads, plugging boxes, plugging bags, plugging umbrellas, etc., by blocking the inner or outer walls of the cabin to prevent external seawater from entering the cabin. External auxiliary equipment is often required for locking and fixing. However, due to the high time requirement for plugging and the strong impact of sea water, it is necessary to quickly carry out the plugging operation, otherwise it may not only cause the hull to sink, but also damage the bulkhead. Make the crack bigger, so the use of auxiliary equipment is not conducive to fast fixing and plugging

[0003] On the other hand, the hull, especially the ship, sails at a fast speed and changes directions. If a leak plugging bag or a leak plugging umbrella is used, it is easy to cause a corner of it to warp, allowing seawater to enter the cabin. Azimuth plugging, the buoyancy on both sides of the hull is not equal, affecting the direction of navigation
