Description

Technical Field

[0001] The utility model relates to the field of underground coal mining, in particular to a device for detecting the water-conducting fissure zone in the underground coal mining face. Background Technique

[0002] During the coal mining process, especially during underground coal mining, the detection of the water-conducting fissure zone is one of the key links to ensure safe production. The water-conducting fissure zone is the crack or fault generated in the underground rock formation due to stress. These cracks or faults may become the channels for groundwater, affecting the drainage and stability of the mine. Therefore, accurately detecting the position and scope of the water-conducting fissure zone is of great significance for the safe production of coal mines. There are some deficiencies in the installation and use of traditional underground coal mine water-conducting fissure zone detection devices. First of all, the installation of the detector and the detection joint usually requires cumbersome steps and tools, which not only reduces work efficiency but also increases the installation difficulty. Secondly, due to the complex and changeable underground working environment, the connection between the detector and the detection joint is prone to looseness or detachment, resulting in inaccurate detection data or detection interruption. These problems not only affect the accuracy of the detection work but also may pose a threat to the safe production of coal mines. For this reason, we propose a device for detecting the water-conducting fissure zone in the underground coal mining face. Content of the Utility Model

[0026] Please refer to Figures 1-5 , a water-conducting fissure zone detection device for coal mining faces underground in coal mines, including a detector main body 1, a function button 2, a detection line 3, and a display screen 11. The display screen 11 is fixedly installed on the top of the detector main body 1, and a function button 2 is movably connected to one side of the display screen 11 on the top of the detector main body 1. A detection line 3 is movably connected to one side of the detector main body 1, and further includes:

[0027] One end of the detector main body 1 is provided with a fixing device for quickly installing the detection line 3;

[0028] One end of the detection line 3 is provided with a nut 7 for strengthening the connection between itself and the fixing device.

[0029] Furthermore, there are two detection lines 3, and one end of each of the two detection lines 3 is fixedly connected to a detection line connector 4, and detection heads are installed at the other ends of the two detection lines 3, and connection blocks 10 are fixedly connected at the joints between the two detection lines 3 and the two detection line connectors 4.

[0030] Furthermore, there are two nuts 7, and circular holes are opened on one side of each of the two nuts 7, and the inner walls of the two nuts 7 are threaded.

[0031] Furthermore, both connecting blocks 10 are in the shape of "I", and the inner portions of the "I" shapes of the two connecting blocks 10 are respectively movably connected to the circular holes of the two nuts 7. The two probe wire connectors 4 are respectively located on one side of the threaded ends of the two nuts 7, and the two probe wires 3 are respectively located outside the two nuts 7.

[0032] Furthermore, the fixing device includes an installation pipe 6, a clamping pipe 8, and a limiting ring 9. Two installation pipes 6 are fixedly connected to one side of the detector body 1. Limiting rings 9 are fixedly connected to the outer surfaces of the two installation pipes 6. Clamping pipes 8 are fixedly connected to the inner portions of the two installation pipes 6 corresponding to one side of the detector body 1.

[0033] Furthermore, threaded grooves are respectively opened on the outer surfaces of the two installation pipes 6 corresponding to one side of the limiting rings 9 on their own, and the threaded ends of the two installation pipes 6 are respectively threadedly connected to the two nuts 7.

[0034] Furthermore, the two clamping pipes 8 are in the shape of a conical cylinder, and the interiors of the four clamping pipes 8 are all hollow.

[0035] Working principle: When it is necessary to use this detector to detect the water-conducting fracture zone in the coal mine underground mining face, one ends of the two probe wire connectors 4 are respectively inserted into the interiors of the two installation pipes 6. Then, one ends of the two probe wire connectors 4 respectively push and elastically open the clamping elastic piece ends of the two clamping pipes 8, so that the two probe wire connectors 4 penetrate and are inserted into the two interfaces 5. Then, by using the elasticity of the clamping elastic piece ends of the two clamping pipes 8, the clamping elastic piece ends of the two clamping pipes 8 clamp and fix the two probe wire connectors 4 to prevent the two probe wire connectors 4 from detaching from the two interfaces 5. Then, rotate the two nuts 7. Through the threaded connection between the two nuts 7 and the two installation pipes 6, the two nuts 7 drive the two probe wire connectors 4 and the two probe wires 3 to be fixed on the two installation pipes 6 through the two connecting blocks 10. At the same time, when the two nuts 7 are threadedly connected to the two installation pipes 6, the two probe wire connectors 4 are pushed to completely enter the interiors of the two interfaces 5, so that the detector body 1 can receive the detection signals transmitted by the detection heads at the other ends of the two probe wires 3 through the interfaces 5.
