A leak-stopping device for a marine airbag

Abstract

The invention relates to a marine device for stopping leakage by an air bag. The marine device for stopping leakage by the air bag comprises the double-layered air bag, an air inlet valve, an air bagclamping device, an operation rod, a small high-pressure air storage tank and an air guiding rod, wherein the double-layered air bag is a thin-walled double-layered air bag consisting of a sealed inner bag body and a high-intensity outer bag body; the double-layered air bag is formed by combining a bottom conical cavity to a top semispherical shell; the bottom of the double-layered air bag is fixedly connected with the operating rod through the air bag clamping device; the operation rod is in the shape of a hollow long round tube; the small high-pressure air storage tank is placed in the cavity of the operation rod; a tank opening of the small high-pressure air storage tank is connected with the air inlet valve; and the upper end of the air inlet valve is connected with the air guiding rod. The marine device for stopping leakage by the air bag has the beneficial effects that a wedge-shaped structure of the double-layered air bag is adopted, a leakage stopping dimensional range is large, and breakage adaption ability is high; by a conical sleeve type sealing design and double-screw bolt locking, sealing property is ensured, and disassembling is facilitated; and by crank operation, high-pressure gas is released instantly, rapid inflating is realized, and leakage stops rapidly.

Description

technical field [0001] The invention belongs to the field of marine leak plugging, in particular to a marine airbag leak plugging device. Background technique [0002] The hull may be damaged during the voyage, which may bring great harm. After the hull is damaged, seawater will flow into the hull through the damaged opening. If it cannot be controlled early, the seawater inside the hull will continue to increase, and the ship will tilt and have insufficient buoyancy. nick no. Therefore, hull plugging is a first aid measure that is often used after the hull is damaged. In the prior art, the leak plugging devices commonly used at home and abroad can be divided into outboard leak plugging devices and inboard leak plugging devices. Compared with the in-cabin leak plugging device, the outboard leak plugging device mainly uses the water pressure of the outboard seawater to press the plugging parts tightly against the hull shell to break out, and is basically not affected by th...

Problems solved by technology

Nowadays, leak-stopping umbrellas are widely used, but the ubiquitous problems are complex structure, high cost, heavy weight, and inconvenient manipulation

At the same time, the poor matching of air intake control, the narrow size range of the plugging breach and the inability to control the quantitative release of gas in the gas storage tank are also problems of the plugging umbrella.
