Description
Technical field
The present invention relates to a kind of railway locomotive superfine dry powder fire-distinguishing system.
Background technology
Railway locomotive (or being called locomotive engine, authority vehicle, locomotive head) is a kind of rolling stock being used to provide railroad train power.Railway locomotive is easy to produce friction overheated, brake overheating, fuel leakage, oil leak, the insulation ag(e)ing of cable overcurrent, the overheated puncture short of switch board electric elements, the overheated short circuit of engine interior etc. in high-speed cruising, and locomotive meets with the generation that the exceedingly odious weather such as thunder and lightning, high temperature also can cause fire incident.
Locomotive is on fire in operation way, and generally away from city, add surrounding terrain circumstance complication, wait fire fighter to arrive in, railway locomotive often burns by big fire completely.At present, the combustible that locomotive adopts comprises fuel oil, lubricating oil, hydraulic oil, air pipe line, electrical equipment, electric wire, encapsulant, ornament materials etc.; These materials are once be ignited, and flame can spread at short notice to whole intra-locomotive space, cause other combustibles to burn simultaneously, and the intensity of a fire is uncontrollable until locomotive burns completely.
In prior art, locomotive generally only configures portable dry powder fire extinguisher, because narrow space, equipment are crowded, complex structure, once breaking out of fire, portable dry powder fire extinguisher is difficult to put to good use, and the intensity of a fire is difficult to control.When fire occurs, personnel not easily enter, and constitute a threat to life.The existing fire-fighting mode of locomotive has been not suitable with modernization locomotive demand for development, and the railway locomotive fire extinguishing system therefore developing extinguishing effect better is technical problem urgently to be resolved hurrily.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of railway locomotive superfine dry powder fire-distinguishing system, can realize effective fire extinguishing, and automaticity is high to all kinds of fire occurred in locomotive.
Realize the technical scheme of the object of the invention:
A kind of railway locomotive superfine dry powder fire-distinguishing system, comprise multiple can the ultrafine dry powder extinguishing installation that starts of automatic detection, it is characterized in that: each bin of railway locomotive is equipped with one can the ultrafine dry powder extinguishing installation that starts of automatic detection; Also be provided with ductwork type ultrafine dry powder extinguishing installation main frame, ductwork type ultrafine dry powder extinguishing installation main frame connects eruption main line, and eruption main line is provided with multiple shower nozzle; Eruption main line is connected to multiple arm, and the bin correspondence of each railway locomotive is provided with an arm, and the outlet of arm is positioned at bin.
The structure of ductwork type ultrafine dry powder extinguishing installation main frame is be provided with the tank body for splendid attire ultra-fine dry powder extinguishing agent in cabinet, be provided with siphon pipe in tank body, and siphonal upper port is connected with the outlet of tank body; The exit of tank body is provided with eruption element, the external eruption main line of outlet of tank body; Also be provided with nitrogen aerogenesis medicine box, nitrogen aerogenesis medicine box is built with solid nitrogen gas generating compositions, and nitrogen aerogenesis medicine box is provided with electric igniter, and the upper end of nitrogen aerogenesis medicine box is positioned at outside tank body, and the remainder of nitrogen aerogenesis medicine box is positioned at tank body; Nitrogen aerogenesis medicine box sidewall is provided with multiple nitrogen and portals, and this nitrogen portals and to communicate with in tank body.
The eruption element that the exit of tank body is arranged is can at the released membrane of authorized pressure explosion or aluminium film.
The electric igniter of nitrogen aerogenesis medicine box can the interlock signal of receiver gases fire extinguishing control panel or fire alarm main frame start automatically, or manually boots.
The exit of arm is provided with shower nozzle, shower nozzle is established multiple pore for evenly spraying ultra-fine dry powder extinguishing agent, and the size in pore aperture and arm are inversely proportional to the distance of ductwork type ultrafine dry powder extinguishing installation main frame.
Eruption main line is provided with two-way pipeline.
The beneficial effect that the present invention has:
Ductwork type ultrafine dry powder extinguishing installation main frame of the present invention connects eruption main line, and eruption main line is provided with multiple shower nozzle, is also connected to multiple arm, can realize long distance and evenly spray on the way.In prior art, the one-to-two that gas conveyings all both at home and abroad and powder conveying all adopt, the equalizing system of two point four, fed distance is limited, structure for strip cannot solve evenly sprays on the way, thus extinguishing chemical cannot penetrate the scene of a fire of big fire, and cannot effectively put out a fire, helpless especially for the fire taken into account inside and outside the closed bin of multiple distribution.Each bin of railway locomotive of the present invention is equipped with one can the ultrafine dry powder extinguishing installation that starts of automatic detection; Can put out a fire by local space during breaking out of fire, also all can put out a fire in space, accomplish to put out a fire, accident scope can not be expanded again, affect the safe operation of locomotive.Ultra-fine dry powder extinguishing agent selected by the present invention should have broad spectrum activity, can put out A, B, C, E class fire simultaneously.Fire-fighting efficiency is high, and blow-off velocity is fast; High-voltage electrical apparatus short circuit can not be caused during fire extinguishing, not affect the operation of locomotive electric cad system equipment, harmless to human non-toxic, safety and environmental protection, easily cleaning after fire extinguishing.
Ductwork type ultrafine dry powder extinguishing installation main frame of the present invention is provided with nitrogen aerogenesis medicine box, nitrogen aerogenesis medicine box produces nitrogen by starting electric igniter, thus the ultra-fine dry powder extinguishing agent in stirring tank body, formed after uniform gas powder two-phase flow reaches certain pressure, by eruption element release extinguishing chemical.In prior art, sealing device work with pressure under the environment that high-frequency, many vibrations, the temperature difference are large, reliability cannot ensure, and the non-reservoir pressure modes such as gas type can only be adopted, but the combustion gas under this mode or solid and gas conversion agent are exactly in fact gunpowder, and the high pressure that the instantaneous expansion of gunpowder brings, the strong difficult problem such as recoil, the huge sound make this technology be difficult to apply in the such environment of locomotive.The exclusive eruption structure that the present invention adopts, perfectly solve this problem, the adverse circumstances such as sharp pounding, the temperature difference is large, greasy dirt is many, dust is large can be adapted to, easy care is even non-maintaining, can taming driving gas more superior to stored-pressure type be produced, can as requested extinguishing chemical be transported to again at a distance.
The electric igniter of nitrogen aerogenesis medicine box of the present invention can the interlock signal of receiver gases fire extinguishing control panel or fire alarm main frame start automatically, can link, realize self-extinguishing with the detector of existing warning system and main frame, more convenient to operate.
The eruption element that the exit of tank body of the present invention is arranged is at the released membrane of authorized pressure explosion or aluminium film, can guarantee that hair spray only starts under prescribed conditions, ensure high security, the high reliability of whole system.
The exit of arm of the present invention is provided with shower nozzle, shower nozzle is provided with multiple pore for evenly spraying ultra-fine dry powder extinguishing agent, the size in pore aperture and arm are inversely proportional to the distance of ductwork type ultrafine dry powder extinguishing installation main frame, to ensure better sprinkling extinguishing effect.
