Then send alarm.The alarm can be audible alarm, text information alarm etc..
Cable protecting device 6 is used for the temperature sensing cable 1 for protecting goaf.
It is following that goaf fire location detection and the implementation process for quick and precisely positioning fire location and alarming is discussed in detail.
For accurate detection goaf high temperature location, temperature sensing cable 1 is routed to the goaf part that coal spontaneous combustion may occur.Not
With embodiment in, in the goaf that may be under fire, according to single channel one continuous line arrangement, multichannel horizontal arranging mode,
Multichannel tilt layout etc. lays temperature sensing cable 1.Specifically please respectively referring to the temperature-sensitive electricity of each embodiment in Fig. 2~4
The arrangement schematic diagram of cable 1.
Assuming that coal-face tilt length is 200m, it is intended in the goaf area detect using the device, predict burning things which may cause a fire disaster position
Put, the specific paving mode and measuring method of temperature sensing cable 1 are described below.From the least significant end of goaf, temperature sensing cable 1 starts
Arrangement, the single channel one continuous line arrangement as shown in Fig. 2 of first embodiment, it is to arrange first along working face incline direction
Length (in present embodiment, first length is 200m), then move towards direction to working face and turn back that (this is pre- for a preset length
If length is a scope, i.e. 5~10m), the working face incline direction laying length of temperature sensing cable first (200m) is continued on, with
This analogizes, and untill laying full whole goaf coal spontaneous combustion " oxidized zone ", temperature sensing cable 1 extends in place via stope drift active workings
The interface of analyzer 100 is put, is connected with Position Analyzer 100.
Multichannel horizontal arranging mode as shown in Fig. 3 of second embodiment, it is to move towards direction along working face to arrange some (these
It is 4~5 in embodiment) the second length (second length is a scope, i.e. 150~200m) temperature sensing cable 1 (adds protection
Device 6), temperature sensing cable 1 extends to the multi-channel interface of Position Analyzer 100 via tunnel, is connected with Position Analyzer 100.
Multichannel tilt layout as shown in Fig. 4 of the 3rd embodiment, it is to tilt a preset angle along working face tendency direction
Degree (in present embodiment, the predetermined angle is 30 °) is simultaneously spaced the 3rd length (in present embodiment, the 3rd length is 20m)
Arrange the sense of some articles of (being 4~5 articles in present embodiment) the 4th length (in present embodiment, the 4th length is 200m)
Warm cable 1 (adding protection device 6), temperature sensing cable 1 extends to the multi-channel interface of Position Analyzer 100 via tunnel, with position
Analyzer 100 is connected.
When all temperature of goaf are normal, multiplex pulse transceiver 2 launches pulse signal, and signal is delivered to temperature sensing cable
1 terminal and multiplex pulse transceiver 2 of turning back, Position Analyzer 100 are not detected by burning things which may cause a fire disaster information, display screen by analysis
4 displays are normal.
And the temperature around goaf temperature sensing cable 1 is when reaching a predetermined temperature or falling within the scope of a predetermined temperature, sense
Warm cable 1 is experienced environment temperature and raised, and the temperature sensing material inside temperature sensing cable 1 melts, and causes in temperature sensing cable 1
Two wires are connected, and automatic short-circuit.In the present embodiment, at the predetermined temperature or the predetermined temperature range
Interior, temperature sensing cable 1 can fuse and cause the short circuit of temperature sensing cable 1.The impulse wave now launched by multiplex pulse transceiver 2
It will be turned back multiplex pulse transceiver 2 in fault position.Position Analyzer 100 is by analyzing the pulse signal sent back, knot
The arrangement for closing temperature sensing cable 1 is analyzed to obtain the distance of the short circuit of temperature sensing cable 1, and determines fire location.
Specifically, warning circuit, because the short circuit of temperature sensing cable 1 has made warning circuit form loop, alarm 5 is alarmed.Together
Alarm device 5 can send alarm signal.Position Analyzer 100 calculated by way of sending pulse to temperature sensing cable 1 short circuit away from
From, while according to the arrangement mode of temperature sensing cable 1 and short circuit duration extrapolates alert locations and burning things which may cause a fire disaster developing direction first.Multichannel
Impulse ejection receiver 2 launches pulse signal to temperature sensing cable 1, when short trouble occurs for temperature sensing cable 1, the arteries and veins that sends out
Rush signal and reach meeting home position analyzer 100 after trouble point (that is, fault position), utilize following formula to calculate fault position
The length of temperature sensing cable 1 between Position Analyzer 100, finally with reference to laying figure (the arrangement signal of temperature sensing cable 1
Figure), you can determine fire location；According to the short circuit duration first of temperature sensing cable 1, burning things which may cause a fire disaster developing direction is calculated.
L=V × T/2 (1)
In formula：
The length of temperature sensing cables 1 of the L between fault position and Position Analyzer 100, unit m；
V is spread speed of the pulse signal in temperature sensing cable 1, unit m/s；
T is to launch the time difference with return pulse signal, unit s.
Assuming that goaf burning things which may cause a fire disaster scope is larger, single temperature sensing cable has been not enough to the position of accurate forecast burning things which may cause a fire disaster, can use with
Lower scheme accurately detects flame range scope：
Specifically, the multichannel horizontal arranging mode as shown in Fig. 3 of second embodiment, the temperature around passage 1 reach
When to a predetermined temperature or falling into a predetermined temperature range, the automatic short-circuit of temperature sensing cable 1, siren 5 is alarmed, recorded
The time T to alarm first1；Similarly, when passage 2 is also alarmed, the time T of alarm is recorded2；Obtain by that analogy
T3、T4、T5... Position Analyzer 100 calculates short-circuit distance by way of sending pulse to temperature sensing cable 1, while according to sense
The arrangement mode of warm cable 1 determines alert locations；The time that each passage obtained using record is alarmed first, calculate each alarm point
Time of fire alarming it is poor, infer speed and the direction of burning things which may cause a fire disaster sprawling, and then the scope and developing direction of accurate forecast burning things which may cause a fire disaster.
Cable protecting device 6 be sheathed on temperature sensing cable 1 by fire proofing wood texture into compression resistance pipe, for whole process protect
Shield temperature sensing cable 1 is not pounded disconnected by mechanical force.In present embodiment, cable protecting device 6 is an iron tripod, and use is removable
Structure is unloaded, inside scribbles insulating paint.In another embodiment, cable protecting device 6 is a hollow round steel pipe.At it
In his embodiment, cable protecting device 6 can also be the hollow pipe of other fire proofing materials composition, and its shape can also be
Triangle, square, ellipse etc..
Those skilled in the art are it should be appreciated that the embodiment of the above is intended merely to the explanation present invention, and is not
Limitation of the invention is used as, as long as within the spirit of the present invention, what embodiment of above was made suitably changes
Become and change all falls within the scope of protection of present invention.
