Abstract
The invention discloses an automatic fire-extinguishing system of an automobile engine cabin, which comprises a fluid reservoir, an electric control water pump, a pressure opening valve, an air release valve, an injection track, an alarm lamp, an ECU, a smoke sensor, a manual control circuit and the like, wherein the main principle is that a matrix smoke sensor of a forecabin automatically monitors the fire situation of the forecabin, once the forecabin starts to smoke, the sensor immediately inputs signal to the ECU, the ECU immediately starts the water pump to inject a fire-extinguishing agent through a fire-extinguishing agent track to all the parts of the forecabin to quench, an oil line is simultaneously and actively quenched and protected, and thereby the automatic fire-extinguishing system can eliminate danger when the fire danger is initially generated, prevent the fire from rapidly spreading to an oil tank along the oil line so as to protect the safety of people, and under the condition of failure extinguishment, the automatic fire-extinguishing system can give passengers more time to escape. In addition, when on fire, sometimes a wire harness may be on fire, at this time, an automatic control may fail to work, the alarm lamp does not light, but a driver can find out the sign of a fire and even smells the pungent smoke, so a manual switch is pressed down, and a fire-extinguishing device can also start to extinguish.
Description
Technical field
The present invention relates to a kind of automatic fire-extinguishing system of automobile engine cabin.
Background technology
The orthodox car extinguishing device is with car band fire extinguisher, when enging cabin is on fire; Want portable steel cylinder, hatchcover is put out a fire before opening, and this mode not only can not in time just begin fire extinguishing in the very first time that fire produces; Affect best attack time adversely, but also have sizable danger, the manual extinguishing will be near vehicle after all; If the vehicle blast, promptly there is following technical problem in the very big threat of safety formation to the people: existing automobile extinguishing device on fire in the prior art; The complex steps of putting out a fire, time lag, weak effect.
Summary of the invention
The object of the present invention is to provide a kind of automatic fire extinguishing system of safe and reliable automobile engine nacelle; Can when the automobile engine nacelle breaking out of fire, in time put out a fire; The personal safety of guaranteeing the passenger with reduce property loss, it is monitored fire signal through sensor, in case that front deck begins to smolder is on fire; Immediately start the front deck automatic fire extinguisher; Can not only be in the very first time more effective eliminating fire dangerous situation, even and knocking out under the front deck situation on fire of failing, also can strive for that more time escapes to the passenger.
Automobile automatic fire extinguishing system of the present invention is made up of systems such as fluid reservoir, electric control pump, pressure operable valve, vent valve, injection track, alarm lamp, ECU, Smoke Sensor and manual control circuits; Cardinal principle is to monitor front deck situation on fire automatically according to front deck configuration Smoke Sensor, in case front deck begins to smolder, sensor inputs to ECU with signal at once; ECU starts water pump at once and extinguishing chemical is ejected into front deck through the extinguishing chemical track puts out a fire everywhere; And oil circuit carried out the active flame failure protection, thereby when just beginning to produce disaster hidden-trouble, remove the dangerous condition; And prevent the intensity of a fire towards the oil circuit rapid spread to fuel tank; The person is produced safety hazard, under the situation of fire extinguishing that fails, also can strive for more escape time to the passenger.The time on fire in addition, possibly be that wire harness is on fire sometimes, at this time, possibly control malfunctioningly automatically that alarm lamp does not work, but the driver has found sign on fire, even has smelt pungent smoke that at this moment press hand switch, extinguishing device also can start fire extinguishing.
Concrete technical scheme is following:
A kind of automatic fire-extinguishing system of automobile engine cabin; Comprise sensor; The ECU ECU and the pump housing; Said sensor is placed in engine place front deck and is used to monitor front deck situation on fire, thereby said ECU ECU is connected with the sensor communication and the signal that is used to accept sensor sends control signal, and the said pump housing can be controlled and is used for to front deck ejecting extinguishing material by ECU ECU.
Further, said sensor is Smoke Sensor (4), and it is arranged in engine place front deck for a plurality of configurations that are.
Further, the said pump housing is electronic water pump (13), and the one of which end is connected with fluid reservoir (3) through connecting line one (1), and the other end connects many injection tracks (12) that are provided with in the front deck of engine place through connecting line two (2).
Further, spray track (12) and go up setting, be used for outside ejecting extinguishing material, spray track (12) end and also be provided with a plurality of vent valves (6), be used for air in the emptying pipeline by many places pressure valve (5).
Further, also comprise a manual switch (8), it is arranged in the driver's cabin, can begin or stop fire extinguishing by manually carrying out the switch control pump housing.
Further, the position in exhaust side, wire harness box and the sets of lines of the outlet of said pressure valve (5) aligning engine, pipeline road, inflammable and ignitable place such as gas handling system.
Further, also comprise alarm lamp (9), it is placed in the bridge instrumentation dish, and it is connected to ECU ECU through electrical connection and/or communication link, and can be by the ECU gauge tap.
Further, also comprise relay switch (7), it all is connected battery (10) with alarm lamp (9), and said relay switch (7) is connected to electronic water pump (13).
Compare with present prior art, the present invention and Engine ECU are integrated, not only reduce cost but also be prone to arrange.Adopt the extinguishing chemical pressure charging system, can in time start and not incur loss through delay opportunity of combat, and safe and reliable.
Description of drawings
Fig. 1 is an overview of the present invention
Among the figure:
1-connecting line one, 2-connecting line two, the 3-fluid reservoir, the 4-Smoke Sensor, the 5-pressure valve, the 6-vent valve, the 7-electronic relay, the 8-hand switch, the 9-alarm lamp, the 10-battery, 11-controller ECU, 12-sprays track, 13-electronic water pump, 14-enging cabin
The specific embodiment
Describe the present invention according to accompanying drawing below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
The signal that present embodiment is gathered according to the Smoke Sensor of enging cabin device offers controller, and controller starts warning device and electronic water pump, sprays the pressure rising opening pressure valve of track, and extinguishing chemical is sprayed onto dangerous spot through pressure valve, puts out a fire.
As shown in Figure 1, fluid reservoir 3, electric control pump 13 connect through pipeline 1, and pressure valve 5 is arranged in sprays on the track, install back application vent valve 6 air in the pipeline is drained.The outlet of pressure valve should mainly face toward inflammable and ignitable place, like the position in exhaust side, wire harness box and the sets of lines of engine, pipeline road, gas handling system etc.Engine electric-controlled pump and fluid reservoir can be arranged in the driving cabin or the position that is difficult for causing danger.Alarm lamp 9 can be placed in the combination instrument, also can be placed on the position that the driver is prone to see separately.Hand switch 8 should be placed on position hidden on the instrument desk, and sticks warning marker, should not start when dangerous situation takes place.
