Description
Technical field
The present invention relates to automatic fire extinguishing technology field, more particularly to a kind of temperature and the extinguishing device of pressure release.
Background technology
In recent years, with the fast development of New Energy Industry, new-energy automobile also goes on fast traffic lane, new-energy automobile by
Year is incremented by.Because of the increase of new-energy automobile, new-energy automobile event on fire also increases year by year, solid in itself mainly due to lithium battery
Some activities, cause battery unstable, be squeezed, collide, short circuit situations such as, be easy to cause battery catches fire, cause huge
The big person and property loss, while bring great negative effect to social stability.In the fast development of New Energy Industry
Meanwhile it is badly in need of a kind of technology that can effectively stamp out a fire, the technology for being provided simultaneously with actively and passively erupting carries out putting out fire
Calamity, escorts for New Energy Industry, to greatest extent the protection person and property safety.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of extinguishing device of temperature and pressure release.
A kind of extinguishing device of temperature and pressure release proposed by the present invention, including annular wrapper and powder column, annular bag
Fill layer and form the ring packing space filled with extinguishing chemical, be liquid under extinguishing chemical room temperature；Powder column is installed on annular wrapper
In inner ring, powder column is equipped with igniter, and igniter is electric control element；Under igniter working status, powder column spontaneous combustion is simultaneously put
Heat.
Preferably, the boiling point of extinguishing chemical is 50-60 degree.
Preferably, extinguishing chemical is fluorinated ketone liquid.
Preferably, there is gap between powder column and annular wrapper.
The extinguishing device of a kind of temperature and pressure proposed by the present invention release, wherein, extinguishing chemical has automatic eruption and passive
Erupt two kinds of working methods.Automatically the realization erupted, starts powder column by external signal；Specifically, external equipment monitor it is different
Often, signal is sent, powder column burns rapidly, produces high temperature, and extinguishing chemical gasifies rapidly, and pressure increases sharply in annular wrapper, reaches
To the pressure-resistant limit of material, annular wrapper ruptures rapidly, discharges extinguishing chemical.The realization passively erupted, passes through annular wrapper
High temperature melt and extinguishing chemical gasification are realized；Specifically, when ambient temperature raises suddenly, the short time promotes extinguishing chemical rapid
Gasification, reaches annular packaging layer material tenability limit, and annular wrapper melts rapidly, releases gaseous fire extinguishing agent, stamp out a fire.
In the present invention, decomposed rapidly after the release of extinguishing chemical gas, a large amount of heat absorptions, with reference to oxidized molecules, put out rapidly fire
Calamity.
A kind of extinguishing device of temperature and pressure release proposed by the present invention, realizes erupting certainly under hot conditions, solution
The prior art of having determined is applied to the technical problem such as gas extinguishing agent volume is big of interference and the destruction of lithium battery.The present invention realizes
Fire extinguishing procedure can in real time, reliably, efficiently provide the fire extinguishing after fire occurs and cooling function without manual intervention.
Brief description of the drawings
Fig. 1 is the extinguishing device structure chart that a kind of temperature proposed by the present invention and pressure discharge.
Embodiment
With reference to Fig. 1, a kind of extinguishing device of temperature and pressure release proposed by the present invention, including annular wrapper 1 and medicine
Column 3.Annular wrapper 1 forms the ring packing space filled with extinguishing chemical 2, is liquid under 2 room temperature of extinguishing chemical.Specifically, ring
Shape wrapper 1 is filled up by the extinguishing chemical of liquid, and after extinguishing chemical 2 gasifies, annular wrapper 1 is burst rapidly, is gone out so as to discharge
Fiery agent；Alternatively, annular wrapper 1 melts rapidly in hot environment, gaseous extinguishing chemical 2 is released.The gasification release of extinguishing chemical 2
Afterwards, extinguishing chemical decomposes, and a large amount of heat absorptions, with reference to oxidized molecules, stamp out a fire rapidly.In present embodiment, in order to ensure extinguishing chemical
Gasification opportunity and speed, fire extinguishing in time, reduces loss, the boiling point of the extinguishing chemical 2 used can specifically be fluorinated for 50-60 degree
Ketone liquid is as extinguishing chemical.
Powder column 3 is installed in the inner ring of annular wrapper 1, and powder column 3 is equipped with igniter, and igniter is automatically controlled member
Part.Under igniter working status, 3 spontaneous combustion of powder column and heat release.In this way, the extinguishing device that present embodiment provides, can coordinate outer
Portion's equipment uses, and fire detection early warning is carried out by external equipment, and when there is fire, external equipment produces external signal and uses
In starting ignition device, so as to light powder column 3, the environment temperature where extinguishing chemical 2 is improved by 3 combustion heat release of powder column, so that
Put out a fire so that extinguishing chemical 2 discharges after gasifying rapidly.The setting of igniter, is the extinguishing device away from hot spot
Startup provides chance, is conducive to the release by peripheral extinguishing chemical 2, prevents fire from spreading in time, so as to reduce loss.And
The extinguishing device of hot spot position, by high temperature melt annular wrapper 1, the extinguishing chemical 2 of release gasification in time, improves
The response speed of extinguishing chemical 2, timely fire containment degree.
In present embodiment, there is gap between powder column 3 and annular wrapper 1, so that powder column 3 has foot in combustion
Enough oxygen supplies, ensure the quick abundant of the burning of powder column 3, so as to improve the response speed of extinguishing chemical.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited to
This, any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme
And its inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
