A kind of marine safety airbag device and its activation method

Abstract

The invention discloses a marine safety airbag device and a starting method thereof, which are installed on the side plate of a ship hull. The airbag device includes a trigger, and a gunpowder chamber for accommodating priming powder and a device for detonating the priming powder in the powder chamber are arranged in the trigger. A primer and an electric detonator, a mechanical trigger for firing the primer and an electric trigger for detonating the electric detonator are arranged outside the trigger, and a mechanical trigger safety is set between the primer and the mechanical trigger, and a mechanical trigger is set between the electric detonator and the electric trigger. The air bag device also includes a combustion gas generator and an air bag connected thereto, and gunpowder is arranged in the combustion gas generator; the marine safety air bag device disclosed in the present invention uses gunpowder deflagration or explosion to make the The air bag inflates quickly, which can provide strong buoyancy for the sinking hull side plate in a short time, effectively preventing the ship from capsizing or sinking.

Description

technical field [0001] The invention belongs to the technical field of marine safety equipment, and in particular relates to a marine safety airbag device and an activation method thereof in the field. Background technique [0002] When a ship capsizes when encountering strong winds or hitting a rock, it will cause a large number of casualties and heavy property losses. The main reason is that the entire process of the ship capsizing is short, only 6 seconds, and passengers have no time to carry Life-saving devices escape. [0003] Although some ship anti-overturning airbag devices are disclosed in the prior art, most of these devices have the problems of slow inflation, low response sensitivity and poor practicability. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a marine safety airbag device and its activation method that can be quickly inflated when the ship capsizes or sinks. [0005] In order to solve t...
