[0002] The positioning accuracy and control ability of traditional drilling devices are limited, and they cannot drill accurately according to the predetermined direction and depth, thus affecting the accuracy and reliability of drilling results. This brings great difficulties to the decision-making and implementation of coal mine water control work, may lead to improper water control measures, and increase the risk of water disasters in coal mines.

[0003] After retrieval, the applicant found that the Chinese patent document disclosed "a drilling protection device for coal mine geological water control", and its publication number is "CN217327208U". This patent mainly sets trapezoidal plates on the lower side edge of the conical cylinder, and encloses a conical cylinder structure through the trapezoidal plates, thereby serving as an extended extension of the conical cylinder to facilitate increasing the internal space of the equipment and facilitating the piling of sand and soil discharged during drilling. However, this patent cannot make the drill bit drill more accurately along the predetermined route, and may not be able to obtain relatively accurate geological and hydrological information during actual use, resulting in misjudgment of information such as the position, thickness and properties of underground aquifers and aquitards. Therefore, we propose a drilling device for coal mine water control. Content of the Utility Model

[0023] Embodiment 1:

[0024] Please refer to the attached Figure 1 -attached Figure 3, A drilling device for preventing and controlling water in coal mines, including a workbench 1. Inside the workbench 1, there is a drilling assembly 2. The drilling assembly 2 includes a first motor 201, a slider 205, and a guide pipe 211. The first motor 201 is connected to a fixed block 203 through a threaded rod 202. The threaded rod 202 is connected to a connecting plate 207 through a moving block 204. The connecting plate 207 is connected to a speed controller 208 and a drill pipe 210 through a second motor 209. A chute 206 is opened on the front of the workbench 1. The slider 205 is slidably connected inside the chute 206. The first motor 201 is fixedly installed on the top of the inner wall of the workbench 1. One end of the threaded rod 202 is fixedly installed on the output shaft of the first motor 201. The other end of the threaded rod 202 is rotatably connected to the inside of the fixed block 203. The fixed block 203 is fixedly installed on the top of the workbench 1. The moving block 204 is threadedly connected to the outer wall of the threaded rod 202. The slider 205 is fixedly installed on the back of the connecting plate 207. The second motor 209 is fixedly installed on the front of the connecting plate 207. The speed controller 208 is fixedly installed on the top of the second motor 209. One end of the drill pipe 210 close to the second motor 209 is fixedly installed on the output shaft of the second motor 209. The guide pipe 211 is fixedly installed on the bottom of the workbench 1.

[0025] The speed controller 208 can adjust the rotation speed of the drill pipe 210 according to different geological conditions and drilling requirements, maintain a stable and appropriate rotation speed, which helps to reduce the vibration of the drill pipe 210, make the drilling process more stable, and thus improve the quality and accuracy of the drill hole.

[0026] Specifically, through the set drilling assembly 2, during the operation of the drilling device, the staff can start the first motor 201. The first motor 201 will drive the moving block 204 to move up and down through the threaded rod 202, and then apply a stable axial driving force to the rotating drill pipe 210. This can ensure that the drill pipe 210 drills along the predetermined direction, reduce the drilling deviation. At the same time, a guide pipe 211 is also installed at the bottom of the workbench 1, which can limit the lateral movement of the drill pipe 210. Coupled with the axial thrust, it can make the drill pipe 210 accurately drill along the predetermined route, so as to obtain more accurate geological and hydrological information.

[0027] Embodiment Two:

[0028] Please refer to Appendix Figure 1 、Appendix Figure 2 And Appendix Figure 4, and on the basis of the first embodiment, it is further obtained that an anti-offset component 3 is provided at the bottom of the workbench 1. The anti-offset component 3 includes a fixed rod 301 and a placement groove 307. Both ends of the fixed rod 301 are fixedly installed on the inner wall of the placement groove 307. Rotating rods 302 are rotatably connected to the inner side surfaces at both ends of the fixed rod 301. A fixed disk 303 is fixedly connected to the circumferential surface of the rotating rod 302. A plug rod 304 is provided inside the fixed disk 303. A magnet 305 is fixedly installed on the top of the fixed disk 303. A storage box 306 is provided inside the side surface of the workbench 1.

[0029] Magnets 305 are also installed on the outer walls of the four support corners at the bottom of the workbench 1. Through the cooperation between the magnets 305, the fixed disk 303 can be adsorbed on the outer wall of the support corner at the bottom of the workbench 1. When the drilling device is not working, the plug rod 304 can be placed inside the storage box 306 to play a role in storage.

[0030] Specifically, through the provided anti-offset component 3, when the drilling device is about to run and work, the staff can take out the fixed disk 303 from the bottom of the workbench 1, and then fix the fixed disk 303 to the ground through the plug rod 304, thereby realizing the fixation of the entire workbench 1. In this way, it can be ensured that the workbench 1 will not shake or displace during the drilling process, providing a stable foundation for the drilling operation and helping to improve the accuracy and quality of the drilling.

[0031] The working principle of the drilling device for coal mine water control of the present utility model: First, before the drilling device is about to run, the staff needs to manually take out the fixed disk 303 at the bottom of the workbench 1, then rotate it through the rotating rod 302 until it is flush with the ground, and then use the plug rod 304 to fix the fixed disk 303 to the ground to achieve the fixation of the workbench 1. Secondly, the staff starts the first motor 201, and the first motor 201 will drive the threaded rod 202 to rotate. Then the moving block 204 will move upward or downward on the threaded rod 202. At the same time, the slider 205 fixedly connected to the connecting plate 207 will also move upward or downward inside the chute 206. At this time, the staff starts the second motor 209, and the second motor 209 will drive the drill rod 210 to perform drilling work. Through the connection relationship between the connecting plate 207 and the second motor 209, a stable axial thrust can be applied to the rotating drill rod 210.

[0032] Of course, the above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model and should be protected by the present utility model.
