Abstract
The utility model relates to fire-fighting mechanical field, is a kind of fireman fire scene breathing equipment.In breaking out of fire, the gas cylinder being equipped with due to fire fighter can be held time shorter, often makes fire fighter's search-and-rescue work be affected, and even threatens fire fighter's self safety.This device is made up of Pressure gauge, pressure reducer, gas cylinder, face shield, portable air feeder, middle air pipe etc., and the fresh air that can utilize the scene of a fire external world provides life support for fire fighter and trapped personnel.
Description
Technical field:
The utility model relates to fire-fighting equipment field, is a kind of device of breathing in the scene of a fire for fireman, the problem of the gas cylinder reserves deficiency being equipped with mainly for fire fighter.
Technical background:
In breaking out of fire, often need fire fighter to enter into and in the scene of a fire, carry out putting out a fire to save life and property or field rescue of fire.And the gas cylinder that fire fighter is equipped with was approximately merely able to maintain about 20 minutes, cannot ensure that fire fighter works long hours in the scene of a fire.Therefore be necessary to provide a kind of simple and easy equipment, the air that utilizes outside, the scene of a fire at narrow rescue site is to fire fighter and rescued personnel source of the gas is provided.
Summary of the invention:
The purpose of this utility model is, the air that utilizes outside, the scene of a fire at narrow rescue site is to fire fighter and rescued personnel source of the gas is provided; Or air respiratorresuscitator is without enough gas storage in the scene of a fire, when fireman cannot arrive safety place again, this device can be fire fighter and trapped personnel provides emergent respiratory gas source.
The utility model patent technical scheme used is:
A kind of fireman fire scene breathing equipment, presses in wireway (7) and second and presses wireway (8) to form by pressing in Pressure gauge (1), pressure reducer (2), gas cylinder (3), face shield (4), first in wireway (5), portable air feeder (6), the 3rd.Wherein gas cylinder (3) is connected with pressure reducer (2), two outlets of pressure reducer (2) respectively at Pressure gauge (1) with in second, press wireway (8) to be connected, face shield (4) can form portable air feeder respiratory system with pressing wireway (7), portable air feeder (6) in the first low pressure wireway (5), the 3rd after being connected, and face shield (4) can form the respiratory system by gas cylinder air feed with pressing wireway (8), gas cylinder (3), pressure reducer (2) in the first low pressure wireway (5), second after being connected.The exit of gas cylinder (3) is connected with pressure reducer (2), pressure reducer (2) has two outlets, one of them outlet is connected with Pressure gauge (1), another outlet is connected with pressing wireway (8) in second, in second, press wireway (8) by after pressing wireway (5) to be connected with face shield (4) in first, the common respiratory system forming by gas cylinder air feed.In the 3rd, press wireway (7) to be connected with portable air feeder (6), in the 3rd, press wireway (7) by after pressing wireway (5) to be connected with face shield (4) in first, jointly form portable air feeder respiratory system.
The beneficial effects of the utility model are, using portable feeder utilizes outside, scene of a fire air at narrow rescue site to fire fighter and being rescued personnel provides source of the gas; Or air respiratorresuscitator is without enough gas storage in the scene of a fire, when fireman cannot arrive safety place again, this device can be fire fighter and trapped personnel provides emergent respiratory gas source.

Detailed description of the invention:
A kind of fireman fire scene breathing equipment, presses in wireway and second and presses wireway to form by pressing in Pressure gauge, pressure reducer, gas cylinder, face shield, first in wireway, portable air feeder, the 3rd.The exit of gas cylinder is connected with pressure reducer, and pressure reducer has two outlets, and one of them outlet is connected with Pressure gauge, and another outlet is connected with pressing wireway in second.Face shield is connected with pressing wireway in first.Portable air feeder presses wireway to be connected with the 3rd.Face shield can be pressed wireway by pressing in first wireway to connect in second, and composition is by the respiratory system of gas cylinder air feed, as shown in Figure 2.Face shield can also be pressed wireway by pressing in first wireway to connect in the 3rd, for fireman provides air, forms portable air feeder respiratory system, as shown in Figure 3 by portable air feeder.
The course of work of the present utility model is:
Under normal circumstances, use respiratory system that face shield and gas cylinder form air feed to provide breathe air for fire fighter.Compressed air in gas cylinder is decompressed to through pressure reducer the pressure that human body can be breathed, and provides fireman to use air by face shield assembly.In the time that gas cylinder lack of air or narrow space cannot use the situations such as gas cylinder air feed, press wireway to disconnect by pressing in first in wireway and second, connect in first simultaneously and press in wireway and the 3rd and press wireway, form and have respiratory system that face shield and portable air feeder form to provide fresh air for fireman, for fire extinguishing and rescue trapped personnel win the quality time.
Claims (3)
