Gas bag type anti-sinking and anti-overturn device

Abstract

The invention discloses a marine emergency anti-sinking and anti-overturning airbag, which comprises an airbag module and an inflator. The airbag module includes a bag body, a base, an outer coating and an inflation hose. It is filled with high-pressure nitrogen, and the piping system includes a high-pressure nitrogen main pipe, a pressure reducing valve, a one-way valve, a solenoid valve and an inflation hose connector. , inflatable hose joint and inflatable hose; through the above technical scheme, the device is less difficult to modify the ship, and the feasibility of the project is higher; the change to the hull is small, and the normal navigation of the ship will not be affected after the modification. It has little impact on the original performance of the ship; the device has simple structure, reliable operation and low cost, and is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of ship vitality, and particularly discloses a ship-used emergency anti-sinking and anti-overturning airbag. Background technique [0002] Ships may capsize or sink due to grounding, collision, encountering severe sea conditions and other reasons. The existing anti-sinking of ships mainly adopts two methods of watertight compartment design and damaged pipe plugging to maintain the vitality of the ship. A marine emergency anti-sinking and anti-overturning airbag is provided to provide compensation buoyancy and restoring moment for the ship in an emergency to prevent the ship from capsizing and sinking. The existing anti-sinking of ships mainly adopts two methods of watertight compartment design and damaged pipe plugging to maintain the vitality of the ship. The existing related patents found in the State Intellectual Property Office are 201520438368.6, and the patent name is a An anti-sinking and anti-overt...

The existing anti-sinking of ships mainly adopts two methods of watertight compartment design and damaged pipe plugging to maintain the vitality of the ship. The existing related patents found in the State Intellectual Property Office are 201520438368.6, and the patent name is a An anti-sinking and anti-overturning airbag device, which proposes to pull and fasten the airbag through a traction rope, has poor stability, and the retraction operation is more complicated. It is necessary to add welding lugs to the bottom of the hull, which will affect the structural strength of the hull and the normal navigation of the ship. Have a certain impact, patent number 201320815925.2, the patent name is the airbag anti-sinking device, an anti-sinking device installed in the compartment of the hull with a flexible airbag, and the water entering the cabin will be discharged outboard through the inflation of the airbag, and the buoyancy of the ship will be increased , this patent restricts the airbags to be installed only in empty cabins, otherwise the equipment or goods in the cabin may puncture the airbags, and another related patent, patent number 201220139987.1, is called the anti-sinking airbag device for ships, which proposes "ships anti-sinking The airbag device uses a chemical reaction to generate gas to inflate the airbag. The temperature of the gas generated by the chemical reaction is high. The initial pressure may be too high to burst the airbag. After a period of time, it will release heat and shrink, and the stability of the airbag is poor.
