Description
Technical field
It the utility model is related to extinguishing device field, and in particular to a kind of Special Automatic detection self-extinguishing dress of diesel locomotive
Put.
Background technology
Railway is national economy main artery, and railway transportation plays huge effect in economic construction of China, but is
Railway transportation provides the locomotive of traction power, and especially diesel locomotive is using diesel oil as fuel, and its oil circuit, circuit are more complicated, machine
Internal temperature is higher in car running, local temperature of flue gas leading up to 600 DEG C, disaster hidden-trouble is very big, while because with oil mass
Big with oil reserve, unit maximum diesel storage amount is up to 1.2 tons of 9000L, lubricating oil, once on fire, the fire spreads quickly, it is extremely difficult to
Control, and train, for the purpose of operating, the fire distinguisher configured is limited, therefore fire once occurs, and is configured on train
Fire extinguisher effect it is very limited, simultaneously because railway, away from fire brigade, train in operation, do not fix by position, to putting out a fire to save life and property
Work brings very big difficulty, and the disaster hidden-trouble of diesel locomotive is concentrated mainly in power room and power house, so onboard
Light-weighted automatic detection automatic fire extinguishing system is configured, while protects the two regions, it is under fire bud, its is fast
Speed suppresses, then can greatly reduce many unnecessary losses.
Mainly there is the fluorine of (1) high-pressure fine water mist fire-extinguishing system (2) seven currently for the automatic fire extinguisher used in diesel locomotive
Propane fire extinguishing system, but both systems are applied and weak point are suffered from diesel locomotive：1st, the fortune of whole fire extinguishing system
Row needs power supply to work, therefore situation about powering off once occurs, then system does not play due effect, and 2, entirely put out a fire
System equipment is complicated, production and maintenance cost are high, 3, the detector used in fire extinguishing system be mostly temperature-sensitive sense cigarette or flame detector,
This kind of detector is difficult to detect early stage in time from the beginning of fire, usually just detects, loses after fire is stretched to a certain extent
Removed optimal attack time, 4, because using single total flooding fire-fighting mode, extinguishing concentration is big, and required extinguishing chemical is more, together
When be not separately provided local fire extinguishment system for keypoint part, do not reach the effect of point-to-point quick extinguishing, 5, using only
Erection system, i.e., each protection zone need to set set of system, have aggravated the load of train.For it is of the prior art it is above-mentioned not
Foot, research are invented a set of more advanced, practical automatic detection automatic fire extinguisher and are particularly important.
Utility model content
The purpose of this utility model is to provide a kind of Special Automatic detection automatic fire extinguisher of diesel locomotive, and it can be effectively

Protect two regions.Visit fire tube and be arranged in the high temperature positions such as flue gas leading from high temperature resistant type, other positions select conventional type.Visit
The signal that the pressure signal feedback device that fire tube end is set is exported is transported to the alarm for being arranged on drivers' cab by connecting line
On device
The utility model compared with prior art the advantages of and have the beneficial effect that：
1st, extinguishing chemical selects ultra-fine dry powder, and its extinguishing concentration is 0.1kg/m3, and heptafluoro-propane extinguishing concentration is 0.7kg/
m3, greatly improved by contrast using ultra-fine dry powder extinguishing agent, its fire-fighting efficiency, foamite amount greatly reduces, extinguishing chemical storage
Bottle product is smaller, and device is lighter.
2nd, using the principle of combined distribution system, a set of equipment protects two regions, fire-extinguishing apparatus utilization rate maximum simultaneously
Change, so that a whole set of fire extinguishing system is lighter, exacerbation train load as small as possible.
3rd, be combined using total flooding fire-fighting mode and the point-to-point local fire extinguishment mode of keypoint part, can in initial stage and
When detect point of origin, trigger device starts, and effectively by the control of fire in the state of initial rudiment, extinguishing chemical usage amount is significantly
Reduce, the extinguishing effect reached is optimal.
4th, for different parts using high temperature and the spy fire tube of ordinary temperature, the feelings that can effectively prevent error starting and not start
Condition.
5th, the signal that the pressure signal feedback device of spy fire tube end is exported is transported to by connecting line is arranged on driver
On the alarm of room, energy and alarm, allow operator on duty to find the condition of a fire in time while fire extinguishing.
6th, double end container value is differential container value, and container value is not limited by scene temperature, and container value two individually controls,
Both sides, which connect, visits fire tube pressure with extinguishing chemical pressure in the bottle holding balance, and one of protection zone is on fire, visits fire tube and is rising
Fiery position explosion, visits fiery overpressure rapid drawdown, the container value of the side is individually opened, to ensure that extinguishing chemical can effectively be sprayed onto fire district
Domain, play a part of partition protecting.
