Drilling and workover operation monitoring system

Abstract

This utility model discloses a drilling and workover operation monitoring system, including a trolley. A disc rotates in the middle of the trolley, and a support plate is mounted on the upper side of the disc. A rectangular frame slides on one side of the support plate, and a horizontal plate is mounted on the upper end of the rectangular frame. A concave support column and two plates are mounted on the upper side of the horizontal plate. An arc-shaped top plate rotates in conjunction with the upper end of the concave support column, and a sound sensing pad is mounted on the upper side of the arc-shaped top plate. A rod rotates between the two plates. This utility model uses the rectangular frame to synchronously raise and lower the sound sensing pad and two gas detection heads. The height of the sound sensing pad and the two gas detection heads can be adjusted according to different downhole channel heights. The rod allows a first rope to be wound around its perimeter and pull one end of the arc-shaped top plate, making it better contact with the surface of smaller cracks or holes to detect smaller sounds.

Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to a monitoring system for drilling and well repair operations. Background Technology

[0002] Gas is a valuable resource buried in coal seams. It is colorless and odorless, cannot sustain breathing, and is prone to explosion when it reaches a certain concentration. Therefore, its mining is dangerous. Gas explosions often occur in coal mining operations, causing serious loss of life and property. In the current technology, gas drainage mainly relies on operators to operate drilling rigs directly in the mine or remotely control drilling rigs.

[0003] Gas leaks produce sounds of varying intensity. The softest sounds are inaudible to the ear and require close proximity to the surface of small cracks or pores for detection. However, the height and angle of the sound detector cannot be adjusted according to the height and angle of the crack or pore, resulting in poor flexibility and limiting its application range, thus reducing detection efficiency. Therefore, there is an urgent need to design a well-drilling and well-workover operation monitoring system to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a drilling and well workover operation monitoring system to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A well-drilling and workover monitoring system includes a trolley with a rotating disc in the center. A support plate is mounted on the upper side of the disc, and a rectangular frame is slidably mounted on one side of the support plate. A horizontal plate is mounted on the upper end of the rectangular frame, and a concave support column and two plates are mounted on the upper side of the horizontal plate. An arc-shaped top plate is rotatably mounted on the upper end of the concave support column, and a sound-sensing pad is mounted on the upper side of the arc-shaped top plate. A rod is rotatably mounted between the two plates, and a first rope is wound around the periphery of the rod. One end of the first rope is fixed to one end of the arc-shaped top plate. Gas detection heads are mounted at opposite ends of the horizontal plate, and a detector body electrically connected to the sound-sensing pad and the two gas detection heads is mounted on the upper side of the trolley.

[0007] Furthermore, a groove is provided on one side of the support plate, the rectangular frame slides into the groove, a sector gear is rotatably fitted in the upper part of the groove, and multiple teeth are installed on the inner side of the rectangular frame.

[0008] Furthermore, multiple teeth mesh with the sector gear, a first motor is installed on the other side of the support plate, the output end of the first motor is fixed to the shaft of the sector gear, and multiple telescopic rods are installed between the support plate and the cross plate.

[0009] Furthermore, the telescopic rod includes a column mounted on the upper end of the support plate, a slide rod slidably fitted at the middle of one end of the column, and a spring mounted between the column and the cross plate, the spring being sleeved around the periphery of the slide rod.

[0010] Furthermore, the upper end of the sliding rod is fixed to the lower side of the horizontal plate, and an I-beam is installed on the upper side of the horizontal plate. The first rope is slidably engaged with the periphery of the I-beam, and the other end of the first rope is fixed to the periphery of the rod.

[0011] Furthermore, a second motor is installed on one side of the plate, and the output end of the second motor is fixed to one end of the rod. A third motor is installed on the lower side of the trolley, and the output end of the third motor is fixed to the central part of the disc.

[0012] Furthermore, a groove is provided at the lower end of the concave support column, and a crossbar is installed in the groove. A second rope is slidably connected between the opposite ends of the arc-shaped top plate and the crossbar.

[0013] The drilling and workover monitoring system provided by this utility model, as described above, has the following advantages:

[0014] 1. By sliding a rectangular frame on one side of the support plate, the sound sensing pad and the two gas detection heads can be raised and lowered synchronously. This allows for height adjustment of the sound sensing pad and the two gas detection heads according to different underground channel heights, effectively improving the flexibility of the device.

[0015] 2. By using the rod, the first rope is wrapped around the perimeter of the rod and pulls one end of the arc-shaped top plate. This changes the tilt angle between the sound sensing pad and the concave support column according to the location of different cracks or holes, allowing it to better fit and contact the surface of smaller cracks or holes, thereby detecting smaller sounds and effectively improving the detection efficiency of the device.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, the drilling and repair monitoring system provided in this embodiment includes a trolley 1, a disc 2 rotatably fitted in the middle of the trolley 1, a support plate 3 mounted on the upper side of the disc 2, a rectangular frame 4 slidably fitted on one side of the support plate 3, a horizontal plate 5 mounted on the upper end of the rectangular frame 4, a concave support column 6 and two plates 7 mounted on the upper side of the horizontal plate 5, an arc-shaped top plate 8 rotatably fitted on the upper end of the concave support column 6, a sound sensing pad 9 mounted on the upper side of the arc-shaped top plate 8, a rod rotatably fitted between the two plates 7, a first rope 10 wound around the periphery of the rod, one end of the first rope 10 fixed to one end of the arc-shaped top plate 8, gas detection heads 11 mounted on opposite ends of the horizontal plate 5, and a detector body 12 electrically connected to the sound sensing pad 9 and the two gas detection heads 11 mounted on the upper side of the trolley 1.

[0024] In this embodiment, a trolley 1 is included, with a disc 2 rotating in the middle of the trolley 1. A support plate 3 is mounted on the upper side of the disc 2, and a rectangular frame 4 is slidably fitted on one side of the support plate 3.

[0025] Specifically, a groove 13 is provided on one side of the support plate 3, and the rectangular frame 4 is slidably fitted in the groove 13. A sector gear 14 is rotatably fitted in the upper part of the groove 13, and multiple teeth 15 are installed on the inner side of the rectangular frame 4.

[0026] Specifically, multiple teeth 15 mesh with the sector gear 14, and a first motor 16 is installed on the other side of the support plate 3. The output end of the first motor 16 is fixed to the shaft of the sector gear 14, and multiple telescopic rods are installed between the support plate 3 and the horizontal plate 5. The first motor 16 can drive the sector gear 14 to rotate, so that the sector gear 14 meshes with the multiple teeth 15 and rotates, thereby driving the rectangular frame 4 to move up and down, in preparation for the next step of adjusting the height of the sound sensing pad 9 and the two gas detection heads 11.

[0027] Specifically, the telescopic rod includes a column 17 mounted on the upper end of the support plate 3, a slide rod 18 slidably fitted in the middle of one end of the column 17, and a spring 19 installed between the column 17 and the horizontal plate 5. The spring 19 is sleeved around the slide rod 18. Through the slide rod 18, the horizontal plate 5 drives the slide rod 18 to extend and retract in the middle of one end of the column 17, so that the slide rod 18 and the column 17 can extend and retract synchronously according to the lifting and lowering of the horizontal plate 5, thereby supporting the lower side of the horizontal plate 5 and making the horizontal plate 5 more stable when it is raised and lowered.

[0028] In this embodiment, a horizontal plate 5 is installed at the upper end of the rectangular frame 4;

[0029] Specifically, the upper end of the sliding rod 18 is fixed to the lower side of the horizontal plate 5, and an I-beam 20 is installed on the upper side of the horizontal plate 5. The first rope 10 is slidably engaged with the periphery of the I-beam 20, and the other end of the first rope 10 is fixed to the periphery of the rod. Through the I-beam 20, the first rope 10 is slidably engaged with the periphery of the I-beam 20, so that the first rope 10 pulls one end of the arc-shaped top plate 8 more smoothly.

[0030] In this embodiment, a concave support column 6 and two plates 7 are installed on the upper side of the horizontal plate 5. An arc-shaped top plate 8 is rotatably fitted at the upper end of the concave support column 6. A sound sensing pad 9 is installed on the upper side of the arc-shaped top plate 8. A rod is rotatably fitted between the two plates 7.

[0031] Specifically, the lower end of the concave support column 6 is provided with a groove 23, and a crossbar 24 is installed in the groove 23. The two ends of the arc-shaped top plate 8 are slidably connected with the crossbar 24 and the second rope 25. Through the second rope 25, the second rope 25 is slidably connected to the periphery of the crossbar 24, so that the arc-shaped top plate 8 is more stable when tilting.

[0032] In this embodiment, a first rope 10 is wrapped around the periphery of the rod body, one end of the first rope 10 is fixed to one end of the arc-shaped top plate 8, gas detection heads 11 are installed at both opposite ends of the horizontal plate 5, and a detector body 12 electrically connected to the sound sensing pad 9 and the two gas detection heads 11 is installed on the upper side of the trolley 1.

[0033] Specifically, a second motor 21 is installed on one side of the plate 7. The output end of the second motor 21 is fixed to one end of the rod. A third motor 22 is installed on the lower side of the trolley 1. The output end of the third motor 22 is fixed to the axis of the disc 2. The third motor 22 can drive the disc 2 to rotate, so that the disc 2 drives the support plate 3 to rotate synchronously. Thus, the support plate 3 drives the sound sensing pad 9 and the two gas detection heads 11 to rotate synchronously. The angle of the sound sensing pad 9 and the two gas detection heads 11 can be adjusted according to the position of the crack or hole.

[0034] Working steps: 1. When it is necessary to adjust the height of the sound sensing pad 9 and the two gas detection heads 11, first move the device into the underground channel, then start the first motor 16. The output end of the first motor 16 drives the sector gear 14 to rotate, so that the sector gear 14 meshes with multiple teeth 15 and rotates, thereby driving the rectangular frame 4 to move upward in the groove 13. At this time, the rectangular frame 4 drives the horizontal plate 5, the sound sensing pad 9, and the two gas detection heads 11 to move upward synchronously. At the same time, the horizontal plate 5 drives multiple sliding rods 18 to slide and cooperate with the middle of one end of multiple columns 17, which can change the length between the sliding rods 18 and the columns 17. At the same time, the horizontal plate 5 drives multiple springs 19 to elastically extend and retract synchronously, so that the horizontal plate 5 moves upward more smoothly. The sound sensing pad 9 and the two gas detection heads 11 can be adjusted to the optimal height for monitoring gas according to the different heights of the underground channel, thus realizing the height adjustment of the sound sensing pad 9 and the two gas detection heads 11.

[0035] 2. When the angle of the sound sensing pad 9 needs to be adjusted, if the area is too small to easily adjust the angle of the device as a whole, start the third motor 22. The output end of the third motor 22 drives the disc 2 to rotate, which in turn drives the support plate 3 to rotate synchronously. Thus, the support plate 3 drives the sound sensing pad 9 and the two gas detection heads 11 to rotate synchronously. The sound sensing pad 9 can be adjusted to the optimal angle for detecting gas leaks according to the different angles of the cracks or holes. After the angle adjustment is completed, start the second motor 21 at the same time. The output end of the second motor 21 drives the rod to rotate, which causes the first rope 10 to wrap around the periphery of the rod and pull one end of the arc-shaped top plate 8, thereby changing the tilt angle between the sound sensing pad 9 and the concave support column 6. At this time, the upper end of the sound sensing pad 9 is in close contact with the smaller cracks or holes. At the same time, the first rope 10 slides around the periphery of the I-beam 20, and the second rope 25 slides around the periphery of the crossbar 24, thus realizing the angle adjustment of the sound sensing pad 9.

[0036] 3. When gas detection is required, the detector body 12 is activated. At this time, the sound sensing pad 9 detects the sound generated when gas leaks, and the two gas detection heads 11 detect the gas. The sound sensing pad 9 and the two gas detection heads 11 transmit the detection data to the detector body 12. The detector body 12 receives and processes the detection data and determines whether a gas leak has occurred based on the information obtained from the data, thus realizing the gas detection work.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
