Fire-fighting air respirator
Technical field
This utility model relates to fire-fighting equipment field, is specifically related to a kind of fire-fighting air respirator.
Background technology
China's " Code for fire protection design of high rise buildings " is by the residential housing of 10 layers and more than 10 layers, and highly public building more than 24m and comprehensive building are drawn and be called skyscraper; In the world generally by height 100 meters with building be called high-rise building. Along with the fast development of China's economic construction, urbanization process is constantly accelerated, and skyscraper continues to bring out.
All the time, Fire Fighting in Tall Buildings is an international fire-fighting difficult problem, fire of high-rise building often have fire spreading rapidly, be easily formed large space solid fire, evacuating personnel difficulty, feature that difficulty of putting out a fire to save life and property is big. Due to the difficulty of evacuating personnel in the restriction of the existing fire extinguishing equipment condition in fire brigade and fire, current fireman is when Treatment for High-rise Building fire, or based on inside fire attack. The a large amount of flammable decoration of the inside and outside use of skyscraper, insulation material can produce high temperature and toxic gas after on fire, the life security of internal trapped personnel and inside fire attack extinguishment fire suppression person can be produced serious threat by this, and therefore fireman wears positive-pressure type firefighting air respirator as respiratory protection harness when carrying out skyscraper fire fighting and rescue inside fire attack more.
Some fire of high-rise building scenes of the accident in recent years, expose the defect that fireman's respiratory protection is not enough, not only have impact on the fight efficiency of fire brigade's fire extinguishing, the executive capability also constraining fireman to search and rescue at fire or the scene of the accident, even affect the life security of fireman. In CCTV on February 9 new address annex big fire in 2009, a fireman is just because respiratory protection deficiency and dies a hero's death. Along with China's skyscraper fire fighting and rescue situation is more and more severeer, fire fighting and rescue task becomes increasingly complex, and this proposes new challenge to the respiratory protection harness of fireman.
Existing fire-fighting air respirator Problems existing:
The function of the air respiratorresuscitator being equipped with at present can not fully meet the demand of the fire fighting and rescue task of complexity.Current domestic air respiratorresuscitator mostly is stem-winder display storage pressure, it is impossible to show the residue tolerance of air respiratorresuscitator gas cylinder intuitively. Fireman does not know about the time that air respiratorresuscitator can be continuing with, and there is the entrance scene of a fire and is excessively deeply finished gas and causes injures and deaths, or the phenomenon such as have stage fright because of no bottom in the heart; Fire missions does not know the actually used situation of the air respiratorresuscitator that in the scene of a fire, fireman wears; Fireman and extraneous voice communication are not smooth, there is fireman and open face shield speech in order to communicate and cause gas leakage, reduce the phenomenon of air respiratorresuscitator time used. 3, lack him and rescue respiratory protective equipment. Owing to evacuating difficulty, often having a lot of trapped personnel in skyscraper fire fighting and rescue process, a lot of firemans, in order to succour trapped personnel, take the malleation fire-fighting air respirator face shield of oneself to captive. In current 11.15 fire, just having a lot of fireman to succour trapped personnel, give the stranded masses air respiratorresuscitator, oneself covers mouth and nose with wet towel. It is done so that not only shorten the time used of air respiratorresuscitator, and shorten the overall respiratory protection time of rescuer, it is impossible to ensure the personal safety of rescuer and captive. Martyr Zhang Jianyong gives the masses air respiratorresuscitator and uses and cause oneself dying a hero's death because respiratory protection is not enough to succour trapped personnel in CCTV on February 9 new address annex big fire in 2009.
Utility model content
This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of can show, use the fire-fighting air respirator that can carry out convenient communication between more comfortable, rescue personnel by digitized. the technical solution of the utility model is: a kind of fire-fighting air respirator, including face shield assembly, air supply pipe, back bracket assembly and gas cylinder, it is characterized in that: described face shield assembly top arranges emitter, face shield assembly is positioned at user of service's mouth position and arranges sound collector, and sound collector connects emitter at face shield inwall by data wire, described back bracket assembly arranges multiple ergonomics breach, described back bracket assembly left and right edges is respectively provided with left side shoulder pad and right side shoulder pad, the material of described back bracket assembly is nylon cotton flameproof fabric, air supply pipe is fixed on the shoulder pad of left side by left side shoulder belt additional strip, left side shoulder pad is connected with back bracket assembly by left side shoulder belt, left side shoulder pad distal outer surface arranges character display, character display is connected with baroceptor, right side shoulder pad is connected with back bracket assembly by right side shoulder belt, right side shoulder pad end arranges receptor and speaker, receptor connects speaker, back bracket assembly arranges band near user of service's waist, described air supply pipe is connected with gas cylinder, is arranged between airflow-reversing valve, and airflow-reversing valve connects the first supply port, and the first supply port is connected with left side shoulder pad by back air supply pipe, and airflow-reversing valve second supplies port.
Further, described emitter uses RFID technique.
Further, described receptor uses RFID technique.
Beneficial effect:
This utility model is by designing ergonomics breach, decrease the overall weight of fire-fighting air respirator on the one hand, on the other hand, it is more convenient for dispelling the heat, and design and more meet ergonomics, improve comfortableness and fitness that air respiratorresuscitator is born, alleviate the physiological stress of fireman, reduce the burden of fireman, extend the use time of air respiratorresuscitator.
This utility model is by arranging electronic displays, it is possible to enable the operating mode that fireman timely and intuitively understands air respiratorresuscitator and the time that can be continuing with, and strengthens the safety that air respiratorresuscitator uses.
This utility model devises speaker and sound collector, fireman need not remove face shield, just can complete rescue personnel's communication each other, strengthen the voice communication contact between fireman, reduce the situation that fireman opens face shield speech and causes gas leakage to communicate.
This utility model is by arranging the second supply port; when rescue personnel runs into, in crisis place, the stranded masses needing to breathe; can pass through to connect the second supply port; such fireman does not need to take the air respiratorresuscitator face shield of self; the respiratory protection time of fireman and the stranded masses can be extended, the life security of protection fireman and saved person simultaneously.
