Marine airbag type fast leak stopper

Abstract

The invention relates to a marine airbag type fast leak stopper. The marine airbag type fast leak stopper is characterized by comprising a composite airbag, an air intake control valve, an airbag fixing sleeve, an operation handle, a miniature high-pressure air storage steel cylinder and an air guide supporting rod, wherein the composite airbag is of a thin-wall double-layer composite structure composed of an inner seal bag body and an outer high-strength bag body, the bottom of the composite airbag is fixedly connected with the operation handle through the airbag fixing sleeve, the miniature high-pressure air storage steel cylinder is arranged in an inner cavity of the operation handle, the opening of the miniature high-pressure air storage steel cylinder is fixedly connected with the air intake control valve, and the upper end of the air intake control valve is connected with the air guide supporting rod. The marine airbag type fast leak stopper has the advantages that a wedge-shaped structure of the composite airbag is adopted, the leak stop size range is large, and hole adaptation capacity is high; conical sleeve type seal design is adopted, dual-stud locking is conducted, seal performance is guaranteed, and meanwhile dismounting is convenient; bangalore torpedo type operation design is adopted, operation is conducted through a stay cord, high-pressure air is released instantly, rapid air inflation is achieved, and rapid leak stop is achieved.

Description

technical field [0001] The invention belongs to a marine leak stopper, in particular to a marine airbag type rapid leak stopper. Background technique [0002] Hull damage is a common and important form of ship damage that may cause great harm. After damage occurs, a large amount of seawater is poured into the hull. If the range of water ingress cannot be controlled, the seawater will flow and increase arbitrarily, which will cause the ship to tilt, reduce buoyancy, and even capsize or sink. Hull plugging is to control the degree of damage after the hull is damaged. Various equipment and tools are used to block holes, loopholes and cracks to prevent seawater from entering. The existing ship plugging equipment at home and abroad can be divided into two types: outboard leak plugging equipment and in-cabin leak plugging equipment. Compared with the in-cabin leak plugging equipment, the outboard leak plugging device mainly presses the plugging parts on the hull with the help of...

AI Technical Summary

Problems solved by technology

It has the following deficiencies: one is that the inflatable air bag used is set on the outer wall of the inner sealing disc lip and the handle, which cannot ensure the sealing performance of the air bag well; the other is that the gas generator is preferred in the patent technical solution The gas source for air bag inflation has high purchase and maintenance costs, and there are potential safety hazards; third, the air intake control is limited by market purchases, and the matching is poor; fourth, it is limited by the size of the reinforcement bracket and the outer sealing plate, so The lower limit of the plugging breach size is too high, resulting in too narrow a plugging breach size range

However, this patent still fails to solve the problems of poor matching of air intake control and too narrow size range of plugging breaches, and the improved airbag sealing structure is not conducive to plastic forming and folding shrinkage
