Coal bed multipoint temperature measuring cable-tray sensor

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 [0001] The invention relates to a multi-point temperature-measuring cable sensor for coal seams, which is used for measuring the internal temperature of coal piles. Background technique [0002] The wide application of coal storage yards and coal storage silos has an urgent demand for sensors for measuring the internal temperature of coal piles. However, the sensors for measuring internal temperature of coal piles in the prior art have the problems of poor wear resistance, poor toughness, and short life, which cannot meet the requirements. Special requirements of coal storage environment. [0003] In recent years, with the in-depth research of carbon nanotube materials, its application fields have become more extensive, but its application in the field of coal field temperature measurement has not yet appeared in the prior art. Contents of the invention [0004] The invention provides a coal seam multi-point temperature measuring cable sensor with high tem...
