A mechanical percussion type marine safety airbag device and its activation method

Abstract

The invention discloses a safety airbag device for a mechanical firing ship and a starting method thereof. The safety airbag device for the mechanical firing type ship is mounted on a ship body side plate; the airbag device comprises a trigger; a gunpowder chamber and a primer are arranged in the trigger, wherein priming gunpowder is accommodated in the gunpowder chamber, and the primer is used for priming the priming gunpowder in the gunpowder chamber; a mechanical firer used for firing the primer is arranged outside the trigger; a mechanical firing safety is arranged between the primer and the mechanical firer; the airbag device further comprises a combustion gas generator and an airbag which is connected with the combustion gas generator; and gunpowder is arranged in the combustion gas generator. According to the safety airbag device for the mechanical firing ship, disclosed by the invention, an airbag can be rapidly inflated by using a gunpowder deflagration or explosion method, and great buoyancy is provided to the sinking ship body side plate within a short time; therefore, a ship is effectively prevented from tilting or sinking. According to the starting method for the safety airbag device for the mechanical firing ship, disclosed by the invention, as action conditions of the mechanical firing safety and the mechanical firer are set, the mechanical firing safety certainly acts prior to the mechanical firer so as to prevent false triggering and ensure that the safety airbag device can be sensitively opened; therefore, the practicability of the starting method is strong.

Description

technical field [0001] The invention belongs to the technical field of marine safety equipment, and in particular relates to a mechanical percussion type marine safety airbag device and its starting method 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 mechanical percussion type marine safety airbag device and its activation method that can be quickly inflated when the ship cap...
