[0025] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0026] An intelligent drilling vibration monitoring device comprises a drill rod 1, wherein a vibration monitoring mechanism 2 is arranged inside the drill rod 1.

[0027] In this embodiment, please refer to Figure 2 and Figure 3 The vibration monitoring mechanism 2 includes a concave bracket 201, and sliders 202 are slidably connected to the left and right sides of the concave bracket 201. Waist-shaped sliding grooves 203 are symmetrically opened on the front and back sides of the concave bracket 201. One end of the slider 202 is connected to a locking screw 204, and the outer thread of the locking screw 204 is sleeved with a double nut group 205. A fixed cross bar 206 is provided at the bottom of the concave bracket 201. The internal rotation of the fixed cross bar 206 is connected to a bidirectional screw rod 207. One end of the bidirectional screw rod 207 passes through the fixed cross bar 206 and is connected to a rotating handle 208. The outer side of the bidirectional screw rod 207 is symmetrically threaded with a screw rod sleeve 209. A housing 210 is installed in the middle of the concave bracket 201. A controller 211, a vibration collector 212, a signal transmitter 213, and a signal processor 214 are installed in the housing 210. The vibration generated at the drill bit is transmitted to the drill rod 1, and the vibration of the drill rod 1 is transmitted to the vibration collector 212. The vibration collector 212 transmits the monitored vibration data to the signal processor 214, which pre-processes the data and transmits it to the signal transmitter 213. After receiving the vibration data, the signal transmitter 213 wirelessly transmits the vibration data to a signal receiver on the surface, thereby detecting the drill bit vibration signal in real time.

[0028] The internal structure size of the concave bracket 201 is adapted to the external structure size of the slider 202. The front and rear sides of the slider 202 are connected with convex buckles that slide with the waist-shaped slide groove 203. The outer wall of the drill rod 1 is symmetrically provided with through holes for the locking screw 204 to pass through. The double nut group 205 adopts Tang's threaded fasteners, and the double nuts of Tang's threaded fasteners are tightened. When tightening, the first nut (usually right-handed) and the second nut (usually left-handed) are screwed into the same locking screw in opposite directions. After tightening, the two work together to provide additional tightening force, which can effectively prevent the impact and vibration loads of the drill bit. When loaded, there will be no loosening and the detection instrument will not fall off, making it safer to use. The top of the fixed cross bar 206 and the bottom of the concave bracket 201 are both provided with rectangular slots for the screw sleeve 209 to slide horizontally. The top of the screw sleeve 209 is connected to the slider 202. The bidirectional screw 207 is made up of two sets of screws with opposite threads. Both ends of the bidirectional screw 207 are rotatably connected to the inside of the fixed cross bar 206 through the bearing seat. The controller 211 is connected to the vibration collector 212, the signal transmitter 213 and the signal processor 214 through wires, and the connection method is electrical connection.

[0029] The working process of the present invention is as follows: the vibration monitoring device is installed inside the drill rod 1 and near the drill bit. It can be adjusted according to the size of the structure inside the drill rod 1. By turning the rotating handle 208, the bidirectional screw 207 is driven to rotate, so that the two sets of threaded screw sleeves 209 move in the same direction or opposite directions to drive the slider 202 to move, and finally the locking screw 204 passes through the outside of the through hole and is fixed with the double nut group 205. After the installation is completed and in normal use, when the drill rod 1 is extended into the cave along with the drill bit, the vibration generated at the drill bit is transmitted to the drill rod 1, and the vibration of the drill rod 1 is transmitted to the vibration collector 212. The vibration collector 212 transmits the monitored vibration data to the signal processor 214, which is pre-processed by the signal processor 214 and then transmitted to the signal transmitter 213. After receiving the vibration data, the signal transmitter 213 wirelessly sends the vibration data to the signal receiver on the surface, thereby detecting the drill bit vibration signal in real time, which is convenient for real-time response to different drilling conditions.
