Description

Technical Field

[0001] The utility model relates to the technical field of drilling radars, in particular to an intrinsically safe drilling radar for mining. Background Art

[0002] When mining minerals, holes are often drilled in advance in the mining area, and radar detection equipment is lowered from the drilling location to survey the depths of the mining area in order to determine the type and content of underground mineral deposits.

[0003] Deep holes in mining areas are often inflammable and explosive types of minerals or contain inflammable and explosive gases. Therefore, intrinsically safe (safe in itself, not prone to sparks and high temperatures) radars are used for detection.

[0004] When using existing borehole radar, a soft tube is generally used to connect the radar probe, so that the probe is inserted into the borehole to detect underground mineral deposits. This method is not easy to control the descent depth when in use, and the soft tube is prone to bending during the deep drilling process and is difficult to reach the predetermined position, resulting in detection errors.

[0005] In order to solve the above problems, it is generally used in conjunction with a hard guide rail or traction equipment. Due to the different models of the guide rail or traction equipment or the different angles of the openings, the connection between the probe and the guide rail is very troublesome.

[0006] It can be seen that there is an urgent need for an intrinsically safe borehole radar for mining, which can make the radar probe easy to connect with different types of guide rails and traction equipment. Utility Model Content

[0034] The radar and radar probe 103 used above are existing devices sold in the market, and the radar probe 103 is simply assembled inside the explosion-proof housing 101 for use.

[0035] Specifically, the explosion-proof housing 101 is completely sealed as a whole, and the bottom of the explosion-proof housing 101 protrudes from the bottom of the extension tube 102 .
