Description
Technical field
The present invention relates to monitoring temperature field, be specifically related to full hole, a kind of big gun hole device for detecting temperature.
Background technology
Bury relatively shallowly district in coal seams such as Xinjiang of China, Inner Mongol, Ningxia, Shanxi, adopt opencast colliery more and more.The airtight measure in spontaneous combustion of coal seam district and goaf causing due to the outcrop of coal seam of open coal mine does not sternly enter air and forms spontaneous combustion district, makes it form a large amount of high temperature big gun holes, temperature up to 500 DEG C, have the temperature of naked light regional location up to more than 1000 DEG C." shotfiring safety code " regulation: at the bottom of hole, big gun hole, temperature is high temperature explosion higher than the blasting operation of 60 DEG C.In the time that big gun hole temperature exceedes 60 DEG C, will take special shotfiring safety work measure, and comprise the cooling of big gun hole, use high temperature resistant explosive and the heat insulation protection of explosive etc.
In blasting operation process, owing to packing explosive in hole into, cause in hole hot gas to emerge forming assembling, cause temperature to raise, even fired charge of explosive ignites.In the operation process of flame range colliery, have at present because of this reason accident of blasting.Therefore, for full hole, flame range big gun hole temperature monitor and and alarm can withdraw in time for operating personnel and equipment etc., ensure that the safety of the person and property is vital.At present, in need to be to hole in the time of blasting operation, temperature be measured.Conventional method is for adopting Ou Pushi temperature measurer or infrared tester to test, after determining temperature, carry out operation, but because big gun hole shape is irregular, have the reasons such as ponding, infrared ray cannot detect the temperature value in whole big gun hole accurately, and infrared ray once can only be tested the temperature value of a point, the temperature value that evenly gathers multiple points for big gun hole, can ensure accuracy and comprehensive, reduces operating risk.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one simple in structure, easy to operate, can adapt to different big guns hole, full hole, the big gun hole device for detecting temperature of the temperature value of multiple points in energy disposable collection big gun hole.Concrete technical scheme is as follows:
Full hole, a kind of big gun hole device for detecting temperature, comprise temperature monitoring (1), temperature sensor (2) and connect described temperature sensor (2) and the wire (3) of temperature monitoring (1), its key is: be also provided with at least one reference test bar (4), described temperature sensor (2) is arranged on described reference test bar (4), this reference test bar (4) is cylindrical, on the sidewall of this reference test bar (4), axially run through and have at least one wire casing (5), described wire (3) is connected with described temperature sensor (2) through crossed beam trunking (5), on this wire casing (5), be provided with fixing-line device (6).
The present invention is work like this: select one or several reference test bars (4) combination according to the degree of depth in big gun hole, reference test bar (4) is stretched in big gun hole, and temperature monitoring (1) detects the temperature value in big gun hole by the temperature sensor (2) being arranged on reference test bar (4).
Described reference test bar (4) is more than two, between adjacent described reference test bar (4), be connected by screw mandrel, simple in structure, the relative position of adjacent reference test bar (4) can well be controlled, and its two reference test bars (4) crossed beam trunkings (5) can be alignd mutually.
Be provided with temperature monitoring hole (7) in described reference test bar (4) bottom, described temperature sensor (2) is arranged in temperature monitoring hole (7), this temperature monitoring hole (7) is near described wire casing (5), and with this wire casing (5) communicates, on the outer wall of reference test bar (4), set temperature monitoring holes (7) can avoid temperature sensor to be blocked by wire (3), temperature sensor (2) is directly contacted with big gun hole, improve the accuracy of temperature value, can avoid temperature sensor (2) to wipe and touch with big gun hole wall stretching in the process of big gun hole simultaneously.
The length of described each reference test bar (4) is 2m, on this reference test bar (4), evenly have four described wire casings (5), on this wire casing (5), be evenly distributed with three described fixing-line devices (6), this fixing-line device (6) is circular arc, and the radius of the radius of this fixing-line device (6) and described reference test bar (4) equates.In actual job, the size operation most convenient of 2m, the assembling that too short needs are too much, wastes time and energy, longly takes, all inconvenience such as transport, the convenience of impact operation.
Described temperature sensor (2) is flexible thermocouple, and flexible thermocouple temperature-measuring range, at-200～1300 DEG C, can be tested fast the temperature of each monitoring point in flame range big gun hole, and can recycle, and is convenient to install, and probe temperature is accurate.
Beneficial effect of the present invention is: simple in structure, and adopt reference test bar to test, can adapt to longitudinal hole, transverse holes, the big gun hole that inclined hole etc. are dissimilar; Adopt many reference test bars detachably to combine, can adapt to the degree of depth in different big guns hole, convenient for collecting and carrying, it is convenient to bring to field work; Crossed beam trunking is set on reference test bar, temperature sensor and wire are all had to defencive function, can effectively prevent temperature sensor and wire and the friction of big gun hole wall in operation, sustain damage.
