Scalability temperature measuring device

Abstract

The invention discloses a scalability temperature measuring device. In order to measure the internal temperature of a coal body, a temperature sensor probe is embedded to realize remote continuous monitoring of the temperature of the coal body. The temperature change and temperature distribution of a coal seam are grasped in real time. The degree of spontaneous combustion and ignition of the coaland the impact range are determined. The existing temperature sensor is improved to overcome the drawbacks of conventional temperature sensors. According to the technical scheme provided by the invention, the device comprises a sensor host which is suspended on a back, and the sensor host comprises a sensor probe; the sensor host is connected with a host computer through a transmission cable; thesensor probe is connected with the sensor host through a signal line; a coal seam temperature collecting hole is drilled in the back, wherein the sensor probe is arranged in the coal seam temperaturecollecting hole; a top plate bracket used for fixing the sensor probe is arranged on the back; and the root of the sensor probe is arranged on a clip of the top plate bracket.

Description

technical field [0001] The invention relates to a temperature monitoring device for the surface of a coal wall in an underground coal mine. Background technique [0002] Spontaneous combustion of underground coal is one of the key prevention accidents in mines. In the event of a fire, it will inevitably cause loss of manpower and material resources and affect normal production. Underground coal seam temperature detection has also become an important part of coal mine safety production. The most prone to fire during coal mining is the process of "two locations" and "three periods". The location is: the lower corner of the downward trough; the upper corner of the upward trough. The three periods are: during the installation of the shelf before coal mining ; during the stoppage of coal mining; during the withdrawal of equipment after coal mining. The existing temperature detection methods generally have infrared temperature detection, which can only detect the surface temperat...

AI Technical Summary

Problems solved by technology

The existing temperature detection methods generally have infrared temperature detection, which can only detect the surface temperature of the coal seam, with large errors and narrow application range.

[0003] Conventional temperature monitoring can only use temperature sensors or infrared thermometers. The temperature sensor can only measure the temperature of the air in the roadway, but cannot measure the internal temperature of the coal body. The infrared thermometer can only measure the temperature of the coal wall surface, and it is artificial operation, dynamic monitoring cannot be achieved
