Description

A kind of dedicated explosion-proof flame-retardant case of aircraft passenger compartment
Technical field
The utility model relates to a kind of dedicated explosion-proof flame-retardant casees of aircraft passenger compartment.
Background technique
Aircraft passenger compartment environment is special: poor compared to open spaces air flow property;Densely populated place, once on fire emit occurs for article Cigarette can cause personnel panic, if emergency disposal is improper, will cause serious consequence;Utilizable fire-fighting resource is limited, goes out Firearm only has a small amount of halon extinguisher and Fire Extinguisher Water;It is limited to dispose fire extinguishment container.
Universal with electronic product, everyone with oneself can the electronic products such as carrying mobile phone, charger baby.It is taken with everyone 2 pieces of lithium batteries of band calculate, as soon as the main cabin of 200 people, the lithium battery having have 400 pieces.Experimental data shows, lithium ion battery Nearly 1000 degree of the temperature of burning, and with the dense smoke and toxic gas of a large amount of penetrating odors.The lithium battery of 18650 models is on fire Explosion also has certain impact force.In addition, also with the risk of re-ignition after lithium battery burning.Fire extinguisher on machine is to a small amount of lithium Ion battery can play preferable extinguishing effect, but or lithium battery multiple re-ignition on fire for a large amount of lithium battery, put out a fire on machine Device wretched insufficiency.Fire extinguisher can also play combustion-supporting effect to the no effect of the burning of lithium metal battery on existing machine.
In recent years, lithium battery repeatedly occurs in aircraft passenger compartment to smolder event on fire, seriously threatens flight safety.According to endless Full statistics, 2016, the main cabin unsafe incidents of 7 dangerous material initiation, this 7 unsafe incidents wholes occurred altogether for China Civil Aviation It smolders for lithium battery is on fire, some of them event has resulted in personnel's slight wound or makes preparation for dropping.By analyzing these events, find Unqualified lithium battery quality is that the big main cause on fire smoldered occurs.Due to aircraft passenger compartment densely populated place, if cannot be to lithium electricity It smolders caused by pond timely disposition on fire, it is easy to injury to personnel is caused, in addition the lithium battery risk on fire for having re-ignition, can cause Personnel are panic, lead to fault spread.It smolders security risk on fire to reduce and take precautions against lithium battery, ensures aviation flight peace Entirely, it is badly in need of wanting a kind of special equipment to carry out the on fire of emergency disposal lithium battery to smolder.
From after American Association package (UPS) cargo airline Dubai aviation accident in 2010, UPS just starts to develop fire-retardant Machine for collecting load copes with the risk on fire of lithium battery cargo.Current experimental result is shown, can prolong resistance lithium ion battery cargo It is on fire, extend the aircraft manipulation processing time, but a large amount of toxic gases and dense smoke of lithium battery generation on fire can not be solved.Also Many America and Europe companies are in exploitation and the industrialization work for being engaged in fire-retardant case and flameproof enclosure, such as Fedex, AmSafe, HighWater Equal companies.Generally, fire-retardant case and flameproof enclosure are and expensive there is also some technological deficiencies at this stage, and there are no molding Product comes out., for bulk supply tariff equipment on fire that be designed research and development of exploding, volume is heavy, is inconvenient to move, operate for these Cumbersome, cracky, maintenance cost are high, are not suitable for aircraft passenger compartment lithium battery Emergency use on fire.
The emergency packet of existing aircraft passenger compartment is not that lithium battery is on fire and design, be equipped with, without explosion prevention function, is resistant to not Nearly 1000 degree high temperature that lithium battery burning generates, does not have the function of filtering dense smoke poison gas yet.Traditional explosion-proof tank volume is huge Greatly, heavy, design is not released stress, is not suitable for aircraft passenger compartment and uses.
Currently, both at home and abroad specifically for the emergency disposal equipment development of the explosion on fire of lithium battery in aircraft passenger compartment also in sky It is white.
