Abstract
The utility model relates to a fire-fighting forcible entry self-rescuing device, which is composed of an oxygen cylinder, a fuel gas cylinder and a mask. The oxygen cylinder is provided with a reducing valve, wherein, one output guide pipe on the oxygen cylinder is connected with the mask, and another output guide pipe is connected with a cutting torch oxygen guide pipe. A fuel cylinder of which the fuel gas output guide pipe is connected with a cutting torch fuel gas guide pipe is provided with a reducing valve for preventing back fire. The device has the advantages that convenient operation and use, and fast cutting of anti-theft devices in fire places; the utility model not only can be used for cutting the anti-theft devices, but also can be used for oxygen absorption for self rescuing, etc. The utility model is the ideal device of fire fighting departments for the forcible entry of the anti-theft devices during fire fighting.
Description
The utility model relates to a kind of fire-fighting orcible entry self-rescuer, and the cutter especially for the Anti-theft door and window of fire fighting belongs to the fire-fighting technical field of tools.
At present, the fire fighting instrument that fire department uses has only fire extinguisher and water under high pressure halter, do not cut the cutter of special uses such as antitheft door curtain, iron railing and the apparatus that the fire fighter saves oneself, fire department is thirsted for having in time cutting the rescuring device that burglary-resisting installation can be saved oneself again in the scene of a fire for this reason.
The purpose of this utility model be to provide a kind of by oxygen cylinder, fuel cylinder, cut, face shield formed, light cutting torch by combustion gas, supply with fire fighter, trapped personnel oxygen by oxygen cylinder, can in time cut the fire-fighting orcible entry self-rescuer that anti-thefting facility can be saved oneself again in the scene of a fire.
The purpose of this utility model is achieved in that it is made of oxygen cylinder, fuel gas bottle, face shield, and its structural feature is: pressure-reducing valve is installed on the oxygen cylinder, and one of the output duct on the oxygen cylinder links to each other with face shield, and another links to each other with the cutting torch oxygen catheter.Fuel cylinder is provided with the anti-backfire pressure-reducing valve.Gas output duct on the fuel cylinder is connected with the cutting torch gas conduct pipe.
The purpose of this utility model can also reach by following technical measures: oxygen cylinder, fuel cylinder are fixed together by back bracket.Oxygen cylinder, all right split setting of fuel cylinder have back bracket on the oxygen cylinder.
Compared to existing technology.The utlity model has following advantage:
1, lack clipping time, the time of cutting φ 20mm low-carbon (LC) round steel, the low-carbon (LC) angle steel of cutting 50mm * 50mm * 5mm was not more than 32 seconds less than 32 seconds;
2, save oneself effectively, the breathing time of saving oneself was at 13-95 minutes;
3, scientific structure design is reasonable, portably uses conveniently;
4, it is low to manufacture cost, is suitable for suitability for industrialized production.
Fig. 1 is the utility model structural representation.
Fig. 2 is an oxygen cylinder of the present utility model, the structural representation that the fuel cylinder split is provided with.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Among the figure, cut (1), pressure-reducing valve (2) (11), fuel cylinder (3), oxygen cylinder (4), back bracket (5), face shield (6), middle pressure safety valve (7), air supply valve (8), oxygen output duct (10,12), the snap joint (9,14) of oxygen output duct, combustion gas output duct (13), gas conduct pipe snap joint (15), cutting torch oxygen catheter (16), cutting torch gas conduct pipe (17), cutting torch (18).
The utility model is designed to two kinds according to the occupation mode of operation region, belongs to a kind of two kinds of forms of inventive concept.By oxygen cylinder (4), fuel cylinder (3), face shield (6), cut (1) constituted.Pressure-reducing valve (11) is installed on the delivery outlet of oxygen cylinder (4), and pressure-reducing valve is equipped with the warning device that is used to report to the police on (11).Export two conduits on the delivery outlet, be connected to the snap joint (9,14) of oxygen output duct on two oxygen output ducts (10,12) respectively.Oxygen output duct (12) with cut the oxygen catheter of (1) (6) be connected, oxygen output duct (10) is connected with the air supply valve (8) of face shield.It is the seamless steel cylinder of 20MPa that oxygen cylinder (4) adopts pressure, and its output pressure is 0.45--0.85MPa, and the blowing pressure is 20-25MPa.Face shield of the present utility model (6) is the positive pressure type full facepiece mask, presses safety valve (7), air supply valve (8) during the bottom of face shield (6) is equipped with.Air supply valve (8) is a positive pressure type air supply valve, and during fire fighting, the fire fighter is with face shield (6) in head, by air supply valve (8) oxygen intake.The delivery outlet of fuel cylinder of the present utility model (3) is provided with anti-backfire pressure-reducing valve (2), and is connected to combustion gas output duct (13), and combustion gas output duct (13) is connected with cutting torch gas conduct pipe (17) by the snap joint (15) of gas conduct pipe.Cut (1) is provided with the control valve of regulating oxygen catheter (16) and the control valve of regulating gas conduct pipe (17), cutting torch oxygen catheter (16), gas conduct pipe (17) link to each other with cutting torch (18) respectively.Dress oil liquefied gas in the fuel cylinder of the present utility model (3), adopting pressure is the seamless steel cylinder of 20MPa.Filling ratio is 0.4, and volume is 3L, and output pressure is 0.45-0.85MPa.
The utility model is designed to two kinds of forms according to the operation region.A kind of form such as Fig. 1, its oxygen cylinder (4), fuel gas bottle (3) are fixed together with back bracket (5), this kind version is used for the work high above the ground fire fighting and uses, another kind of form such as Fig. 2, it is fixing with back bracket (5) that its oxygen cylinder (4) fuel gas bottle (3) split is provided with oxygen cylinder (4), and fuel gas bottle (3) is placed separately.This version is used for fire fighting use on the stratum.
Using method of the present utility model: when meeting the high-altitude fire, back back bracket (5) is with face shield (6).When put out a fire in the stratum, back back bracket (5), portable fuel gas bottle (3) is with face shield (6).When needing cutting orcible entry anti-thefting facility, as antitheft door, iron bar etc., with oxygen cylinder (4), the valve open on the fuel cylinder (3) will cut the fuel gas valve open on (1), light cutting torch (18) with fire and can cut the orcible entry operation, and can regulate the oxygen valve on the cutting torch (18) as required.
When saving oneself, the output duct on the oxygen cylinder (12) is unloaded, the oxygen output duct (10) on the face shield is connected on the oxygen cylinder, be with face shield, the valve of opening on the oxygen cylinder can be saved oneself.
