Description
Technical field
The present invention relates to anti-heavy air bag, refer in particular to a kind of flame-retarding insubmersible air bag unit and application thereof.
Background technology
The boats and ships of countries nowadays in order to prevent that ship is heavy when wrecked, adopt following measure usually; Adopt double bottom and watertight cofferdam, also be provided with emergent draining leak stopping and life boat, be nowhere near,, often have little time escape, but moment causes the heavy people of ship to die because precipitate situation takes place but a large amount of casualties proves above-mentioned measure.Enter the nineties, have anti-heavy air bag to come out, anti-heavy air bag commonly used is divided into two classes substantially:
The first kind is high-pressure aerated class, and as notification number CN1080252A, name is called " ships and light boats week air heave type anti-sink device "; Notification number CN2219855Y, name is called " the promptly anti-heavy airbag apparatus of a kind of boats and ships "; Notification number CN2260053Y, name is called " emergent anti-heavy the subtracting of boats and ships shakes Overthrow preventing device "; Notification number CN2055125U, name is called " anti-sink device of navigating "; Notification number CN1247819A, name is called " a kind of salvaging method of naval vessel ".Its major defect is:
If, need the long time, and often can't inflate because of outage with compressor or pump inflation; If with high-pressure gas cylinder or jar inflation, then not only increase the load carrying ability of boats and ships, increase safety hazard again.
Second class is for pharmaceutical chemicals aerogenesis inflation class, and as notification number CN86103322A, it is to adopt sodium azide (NaN that name is called " inflated water lifesaving appliance "
3) and ammonium nilrite (NH
4NO
2) generated reactive gas; Notification number CN2032987U, it is to adopt black powder to light nitrocellulose (NC) to produce gas that name is called " ship Counter-Flooding device "; Notification number CN85106861A, it is to adopt nitrocellulose (NC) and nitroglycerin (NG) generated reactive gas that name is called " fast speed buoyancy anti-sink device for submarines ".Its common advantage be in light weight, aerogenesis is fast, easy to use, its major defect is:
The pharmaceutical chemicals that adopts is poisonous and inflammable and explosive, has severe toxicity as sodium azide and ammonium nilrite; Black powder and nitrocellulose and nitrocellulose and nitroglycerin are all inflammable and explosive, cause to use to be absolutely unsafe.
External more about the research kind of gas generant, mainly be to overcome azide (NaN
3) toxicity, that wherein representative is WO96-26169 patent (1996.08.29), name is called " compound of gas generator ", and its main component is: the nitrogen-containing compound that acts as a fuel (tetrazolium, triazole, triazine or derivatives thereof and salt), oxidizer, scaling loss improver and minimizing produce the etcetera of noxious gas.Its major defect is: though it has overcome azide (NaN
3) toxicity, but be still with nitrogen-containing compound and act as a fuel, can produce oxides of nitrogen and/or carbonic oxide inevitably.
