Embodiment

[0041] Such as figure 2 and image 3As shown, in this example, in order to better protect the temperature detection and emission device 3, a temperature detection and emission device casing 31 is set outside it. Good corrosion resistance and sealing effect to protect the internal circuit, making this drilling tool suitable for working in harsh environments. Its material can be metals such as gold, silver, copper, etc., and copper is the most suitable in terms of cost performance. In practical application, the housing 31 of the temperature detecting and emitting device is fixed outside the temperature detecting and emitting device 3 and is fixedly connected with it.

[0042] In this example, the connection mode between the temperature detection transmitter 3 and the fixed bracket 2 is as follows: Figure 4 As shown, in order to effectively connect the housing 31 of the temperature detecting and launching device with the fixed bracket, a screw 4 can be provided on the housin...

Abstract

The invention relates to drilling tools, in particular to a drilling tool for detecting temperature in a drill hole in real time. The drilling tool for detecting the temperature in the drill hole in real time solves the technical problems that according to a drilling tool in the prior art, the temperature in the drill hole cannot be detected in real time and cannot be fed back to an operator in time. According to the technical scheme, the drilling tool for detecting the temperature in the drill hole in real time comprises a drill pipe, a fixing support, a temperature detecting emitting device and a signal receiving device; the temperature detecting emitting device is connected with the signal receiving device and the temperature detecting emitting device is fixed to the inner portion of the drill pipe through the fixing support; the temperature detecting emitting device is used for detecting the temperature in the drill hole and sending processed information to the signal receiving device; the signal receiving device is used for receiving the temperature information sent by the temperature detecting emitting device and making a corresponding response according to the temperature information. The drilling tool for detecting the temperature in the drill hole in real time is simple in structure, capable of detecting the temperature in the drill hole in real time and improving the safety and suitable for mine drilling.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a drilling tool for real-time detection of the temperature in a borehole. Background technique [0002] Coal is the main energy source in my country. However, the occurrence and mining conditions of underground coal seams are complex, and the gas content of coal seams in my country is generally high. More than 50% of the coal seams are high-gas coal seams, and high outburst mines account for 44% of the total number of mines in the country. At present, there are many measures for gas control, but in the end it is necessary to drill the coal seam for gas drainage, and drilling is the key link in the construction process. Drilling depth, drilling diameter and drilling quality directly affect the effect of gas control. Especially in the soft coal seam, the hole collapse is serious, the drilling efficiency is low, and the water drilling will further reduce the hole quality, so the air drill becomes...
