Portable down-hole drilling provided in an embodiment of the present invention is mainly used in underground mine fire prison along journey temperature-indicating instrument
Survey, temperature survey can be carried out along the multiple positions of journey to coal mine down-hole drilling.The temperature-indicating instrument is passed by temperature acquisition system, signal
Defeated system, protection device, display and control system composition.The system is integrated and updated to current temperature-indicating instrument, together
When realize along journey step temperature measure.The system can carry out temperature survey to coal mine down-hole drilling along the multiple positions of journey, lead to
The measurement to step temperature is crossed, analyzes influence of the sign such as the coal mine underground coal bed temperature change factor to coal spontaneous combustion, must be produced coal certainly
Temperature Variance trend during combustion, with the ignition quality of Study on Coal.The exploitation of the temperature-indicating instrument is believed for flame range internal temperature
The raising of breath acquisition technique and equipment provides reliable material base, and the popularization and application of the instrument and equipment can be widely used for colliery
During fire extinguishing；There is provided a set of convenience applicable equipment for coal spontaneous combustion prediction and coal spontaneous combustion risk analysis.
(1) temperature acquisition system
Temperature sensor is the core of temperature measuring instrument.The present embodiment selects touch sensor, to make instrument
Precision is high, and thermal resistance selects RTD.RTD can be used for measuring temperature in the range of-200-500 DEG C, can directly use copper conductor
Be connected use with secondary meter.Can be display instrument, recorder, adjuster, scanning because it has good electric output characteristic
Device, data logger and computer provide accurate temperature change signal.RTD outside protective case uses stainless steel, inside fills
High-density oxide insulator, there is very strong antifouling property and excellent mechanical strength, be suitable in mine adverse circumstances
In application.Simultaneously RTD than common assembled RTD have diameter is small, flexible, shock resistance is good, thermal response time is fast,
The advantages that service life is long.
Relation between RTD and temperature can be represented by the formula R close to linear in the range of 0~630.74 DEG Ct=R0
(1+At+Bt 2)；It is R in the range of -190~0 DEG Ct=R0(1+At+Bt2+Ct3).In formula：R0、RtFor 0 ° and t ° of temperature when platinum electricity
The resistance value of resistance, t are arbitrary temp, and A, B, C are temperature coefficient, are determined by experiment, A=3.9684 × 10-3/ DEG C, B=-5.847
×10-7/℃2, C=-4.22 × 10-l2/℃3.It can be seen that by formula, temperature sensor works as R0When being worth different, at the same temperature,
Its RtValue is also different.
In the present embodiment, the quantity of temperature sensor can be set to six, and once drilling can be measured repeatedly, so be saved
Drilling cost is used, and can measure step temperature, economical and practical.
(2) signal transmission system
Signal transmission system can use signal transmission anti-explosion cable, and the information that information source is sent is transformed with after processing, send
Toward channel data signal.Digital transmission system such as has its strong antijamming capability, is easy to store, handle and exchange at the spy
Point.
In digital signal transmission system, the analog signal that information source is sent turns into numeral by the message sink coding of digital terminal
Signal, the data signal that terminal is sent, the data signal of transmission is become suitable for by channel coding, then by modulator
Used in signal modulation to system on digital channel, then opposite end is transferred to, the stay of two nights is ultimately delivered to by opposite conversion.
(3) protection device
Protection device is protection sleeve pipe 4, and steel pipe can be used in the present embodiment, its can include it is multiple can supporting installation steel
Pipe, each length of steel pipe is 1.5m.Steel pipe is divided into 3 types, beginning steel pipe, last steel pipe, middle steel pipe.Per covering device, beginning steel pipe,
Last steel pipe is respectively one, and middle steel pipe can be formed by more.Beginning steel pipe is mainly used in drilling front, is easy to go deep into drilling,
Steel pipe front is circular cone arrow, and binding post is left in steel pipe end；Binding post is left at middle steel pipe both ends, is easy to load and unload,
Last steel pipe end is mainly connected with display and control system 1.The boring of protection sleeve pipe 4, connected using screw thread between protection sleeve pipe 4
Connect, the internal signal output cable of protection sleeve pipe 4 is connected by joint.Every steel pipe is evenly arranged 3 temperature sensors, and senses
Device device locality specific, it is easy to the depth of temperature measurement point.It can be taken using multiple steel tube connecting ways according to drilling depth
With a number of steel pipe, it is easy to flexibly carry.
(4) display and control system
Drilling is logging along the display and control system of journey temperature-indicating instrument, logging shown suitable for multimetering and
Control, integrate more instrument functions, typically can the tunnel measurement signal of inspection 1~64, can circling measurment and display multiple signals,
It is used cooperatively with various kinds of sensors, transmitter, each passage can independently bound controlling alarm, pick-up output, data acquisition
Printing and communication.
Possess omnipotent input function, automatic detecting, manual regular inspection can free switching, inspection channel switching time and passage have
Effect number can arbitrarily be set.Good software platform, possesses ability of second development, to meet special function.Advanced modularization
Structure, coordinate powerful instrument chip, function combination, system upgrade are very convenient.Multiple protective, isolation design, resist and do
Disturb that ability is strong, reliability is high.
In real work, drilled first, temperature-sensing probe sensor is put into drilling, by rotating slowly insertion
Drilling, for temperature-sensing probe because being protected using all steel outer sheath covers, thermal capacity is larger, and the response time is at 1-2 points
Between clock.When being put into required depth, the deep calibration value of record cable in itself, and need the static response for waiting probe enough
Time carries out heat exchange.The change that LCDs shows numerical value is paid close attention to simultaneously, carries out data record.Measurement finishes receipts electricity
During cable, slowly operated using handle, avoid haling, prevent temperature-sensing probe jam, fracture Loss occurs.
In the embodiment of the present invention, measured to reach drilling along journey many places, multiple apertures are set on protection sleeve, and are divided
An Zhuan not a temperature sensor；Temperature sensor directly contacts testee, and logging is sent to by signal output cable；
So as to realize that many places of the drilling along journey measure, and realize that step temperature signal gathers in real time.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art is in the technical scope of present disclosure, the change or replacement that can readily occur in,
It should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be defined.
