[0027] Example:

[0028] See also Figures 1 to 4 The utility model provides a technical solution: a downhole vibration monitoring mechanism, including a connecting ring 1, a threaded rod 3 is threadedly connected to one side of the connecting ring 1, a handle 4 is fixed to one end of the threaded rod 3, a servo motor 6 is movably installed at the other end of the threaded rod 3, a rotating shaft 7 is fixed to the power output end of the servo motor 6, a driving wheel 8 is fixed to one end of the rotating shaft 7, a sleeve rod 9 is fixed to one side of the outer wall of the servo motor 6, a telescopic rod 10 is slidably sleeved on the inner wall of the sleeve rod 9, a driven wheel 11 is fixed to the other side of the connecting ring 1, a connecting plate 12 is fixed to the bottom of the driven wheel 11, a pressure sensor 13 is fixed to one side of the connecting plate 12, a spring 14 is fixed to one side of the pressure sensor 13, an extrusion block 15 is fixed to one end of the spring 14, and an extrusion rod 16 is fixed to one side of the extrusion block 15.

[0029] Among them, two driven wheels 11 are provided, and the two driven wheels 11 are symmetrically arranged about the middle part of the driving wheel 8. The connecting ring 1 is supported by the two driven wheels 11 and the driving wheel 8, so that the two driven wheels 11 and the driving wheel 8 maintain an isosceles triangle shape. The rotating shaft 7 is driven to rotate by the servo motor 6, and the electric driving wheel 8 moves on the outer wall of the pipeline. The driven wheel 11 moves together to drive the connecting ring 1 to move on the outer wall of the pipeline.

[0030] Among them, the extrusion block 15 is arc-shaped on the side away from the spring 14, which reduces the friction between the extrusion block 15 and the outer wall of the pipe, so that the connecting ring 1 can move better. The length of the spring 14 is greater than the horizontal length value of the driven wheel 11. The distance between one end of the extrusion rod 16 and the pressure sensor 13 is less than one centimeter, so that the extrusion block 15 can touch the outside of the pipe. At the same time, when the extrusion block 15 is in contact with the outer wall of the pipe, there is a certain gap between the extrusion rod 16 and the pressure sensor 13. When the pipe vibrates, the spring 14 will follow the vibration, and the extrusion rod 16 can touch the pressure sensor 13.

[0031] Among them, the outer wall of one end of the threaded rod 3 close to the servo motor 6 is rotatably connected with a bearing 5, one side of the bearing 5 is fixed to the outer wall of the servo motor 6, and the other end of the telescopic rod 10 is fixed to the inner wall of the connecting ring 1. The sum of the length values ​​of the sleeve rod 9 and the telescopic rod 10 is equal to half of the diameter value of the inner wall of the connecting ring 1. Through the cooperation of the sleeve rod 9 and the telescopic rod 10, when the threaded rod 3 is rotated, the servo motor 6 will not rotate with the threaded rod 3, and will not affect the lateral movement of the servo motor 6. The threaded rod 3 is driven to rotate by turning the handle 4, and then the servo motor 6 and the driving wheel 8 are driven to approach the outer wall of the pipeline.

[0032] Among them, the diameter value of the driving wheel 8 is greater than the outer wall width value of the servo motor 6, and the vertical section of the driving wheel 8 and the center of the connecting ring 1 are located in the same vertical plane, so that the driving wheel 8 can fit with the outer wall of the pipeline, and the servo motor 6 will not touch the outer wall of the pipeline.

[0033] Among them, a laser lamp bead 2 is fixed on the top of the connecting ring 1, and there are multiple laser lamp beads 2. The multiple laser lamp beads 2 are arranged equidistantly in a circle, and the multiple laser lamp beads 2 are electrically connected to the pressure sensor 13. When the pressure sensor 13 is subjected to pressure, it can generate a signal to control the laser lamp bead 2 to generate laser to irradiate the wellhead, reminding the staff that the pipeline is vibrating.

[0034] The working principle of the utility model is as follows: first, the connecting ring 1 is put on the outer wall of the pipe to be detected for vibration, and the threaded rod 3 is driven to rotate by turning the handle 4, thereby driving the servo motor 6 and the driving wheel 8 to approach the outer wall of the pipe. Through the cooperation of the sleeve rod 9 and the telescopic rod 10, when the threaded rod 3 is rotated, the servo motor 6 will not rotate with the threaded rod 3, and will not affect the lateral movement of the servo motor 6. The diameter value of the driving wheel 8 is greater than the outer wall width value of the servo motor 6. The driving wheel 8 fits the outer wall of the pipe, and the servo motor 6 will not touch the outer wall of the pipe. The driving wheel 8 supports the connecting ring 1 so that the two driven wheels 11 and the driving wheel 8 maintain an isosceles triangle shape. The rotating shaft 7 is driven to rotate by the servo motor 6, and the electric driving wheel 8 moves on the outer wall of the pipeline. The driven wheel 11 moves together to drive the connecting ring 1 to move on the outer wall of the pipeline. After moving to the required position, the servo motor 6 is stopped. When the pipeline vibrates, the spring 14 will follow the vibration, and the extrusion rod 16 can touch the pressure sensor 13. When the pressure sensor 13 is under pressure, a signal can be generated to control the laser lamp bead 2 to generate laser to irradiate the wellhead, thereby reminding the staff that the pipeline is vibrating.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
