Abstract
The invention relates to a coal bed multipoint temperature measuring cable-tray sensor which is used for coal pile temperature measuring. The coal bed multipoint temperature measuring cable-tray sensor comprises a temperature measurement component 1, an inner sheath 2 and an outer sheath 3. The inner sheath 2 is made of teflon materials and is coated on the periphery of the temperature measurement component 1. The outer sheath 3 is made of carbon nanotube composite materials and is coated on the periphery of the inner sheath 2. A temperature measurement range of the temperature measurement component 1 is selected according to needs, but the range is not limited to a bus type temperature measurement component and a digital temperature measurement component. When being applied, the coal bed multipoint temperature measuring cable-tray sensor is paved according to the shape and the characteristics of the coal pile, the sensor can be vertically inserted into the coal pile, or horizontally paved on the bottom of the coal pile, or surrounded around the coal pile, and thus the mode for paving is flexible and convenient. The coal bed multipoint temperature measuring cable-tray sensor has the advantages of being high temperature resistant, impact resistant, pulling resistant and high in abrasion resistance. The defects of being bad in abrasive resistance by being influenced by coal media in the prior art, and short in service life are overcome.
Description
Technical field
The present invention relates to a kind of Multi-point temperature measuring cable-type sensor for coal bed, be used for the measurement of dump internal temperature.
Background technology
The widespread use of coal yard, coal storage silo, demand sensor to the dump inside temperature measurement is urgent, yet the sensor of the dump inside temperature measurement of prior art exists and to wear no resistance, poor toughness, short problem of life-span, can not meet the singularity demand of coal storage environment.
Along with the further investigation of carbon nano-tube material, the field of its application was more extensive in recent years, also occurred but it is applied in the prior art of coal yard thermometric field.
Summary of the invention
The invention provides a kind of high temperature resistant, high abrasion, good toughness, the Multi-point temperature measuring cable-type sensor for coal bed of being convenient to install.Be used for the inner thermometric of dump.
The objective of the invention is to be realized by following technical proposals: a kind of Multi-point temperature measuring cable-type sensor for coal bed comprises the inner sheath 2 of temperature element 1, parcel temperature element 1, the oversheath 3 of parcel inner sheath, temperature element 1 temperature-measuring range as required is selected, be not limited to bus type temperature element, digital temperature element, it is characterized in that oversheath 3 is to be made by carbon nano-tube material.
Described inner sheath 2 is made by polytetrafluoroethylmaterial material high temperature resistant, insulation, plays the effect of protection temperature element.
Advantage of the present invention: the present invention is applied in carbon nano-tube material coal yard thermometric field first, solved the problem that smashes cable formula sensor in the coal storage environment of always wanting to solve in this field because of the impact of coal breakage, a kind of long service life, practical temperature probe are provided for the coal storage user.
Oversheath 3 use carbon nano-tube materials of the present invention are made has very strong mechanical property and heat conductivility.Very high toughness, anti-wear performance have ensured the serviceable life of cable formula sensor, have reached the beneficial effect of effective reduction dump temperature monitoring cost; Well heat conductivility has ensured that temperature element 1 can seriously survey to get the temperature of dump, reduces the temperature measurement data error.

Embodiment
The present invention is according to kind, the dump temperature range of institute's coal storage, and the dump shape is selected classification and the quantity of temperature element 1.The temperature element 1 of respective numbers is adjusted to suitable interval, connects or layout by the prefabricated signal wire on temperature element, is embedded in inner sheath 2, then with temperature element 1, the inner sheath 2 of moulding, is wrapping in oversheath 3.Features of shape according to dump when the present invention uses is laid, and can vertically insert dump, level and be laid on the dump bottom, is looped around around dump, and paving mode is flexible.
In the dump temperature monitoring that is applied in the coal storage facilities such as coal storage silo, circular coal yard, bar shaped coal yard.When using, hang from the silo top that to insert dump inner in silo, fix at the top; When using, Multi-point temperature measuring cable-type sensor for coal bed is vertically fixed on the coal-stopping wall inwall with chuck or U-shaped screw card in circular coal yard; When using, Multi-point temperature measuring cable-type sensor for coal bed is tiled in the dump ground surface in the bar shaped coal yard.Multi-point temperature measuring cable-type sensor for coal bed is connected to the signals collecting instrument by corresponding signal wire with temperature measurement signal.By the instrument to collect signal wire, temperature is uploaded to instrument after temperature element 1 perception dump temperature and show, report to the police and process.
