The invention is further illustrated with reference to the accompanying figures 1-2.
A scalable temperature measuring device comprises a sensor host 3 suspended on a roadway roof 1, wherein the sensor host 3 is provided with a fixed sensor probe which is arranged on the lower part of the sensor host. Different from the prior fixed connection mode, the invention is characterized in that the sensor host 3 is connected with an upper computer through a transmission cable, and can transmit signals to the upper computer to detect temperature data on line in real time.
The sensor probe 4 is connected with the sensor host 3 through a signal wire 5, and a coal seam temperature acquisition hole for installing the sensor probe is drilled in the roadway roof. The sensor probe is connected with the sensor host through a 1-5m signal line, a probe mounting hole is drilled at the top of the coal seam temperature acquisition hole of the roadway roof, and the inner diameter of the probe mounting hole is smaller than or equal to the outer diameter of the sensor probe. The sensor probe is inserted into the probe mounting hole, so that the temperature change condition inside the coal body can be detected on line in real time, and the test process is simple and efficient.
Simultaneously, the device still has the function of detecting the coal seam ambient temperature. The tunnel roof 1 is installed with roof support 7 that is used for fixed sensor probe 4, and the 4 roots of sensor probe are installed on roof support's clip 6.

The metal clip is arranged at the bottom of the top plate bracket and can be used for clamping a signal wire or a probe body of the sensor probe. When the ambient air temperature is measured, the sensor probe is suspended in the air; when the temperature in the coal body or the goaf is measured, the sensor probe is extended into the drill hole in the coal body or the inner side of the goaf. The sensor can monitor and upload simultaneously in real time, and is safe, reliable and convenient to use.
