Description

Technical Field

[0001] The present invention relates to the technical field of wellbore status monitoring, and in particular to a wellbore status monitoring device. Background Art

[0002] With the increase in the depth of coal mining and the increase in equipment in the mine, the pressure on the mine shaft is increasing, so the shaft is very easy to deform and affect its verticality. The shaft is an important part of the entire coal mine, responsible for the transportation of underground workers, equipment and materials such as excavation and coal mining, and the transportation of raw coal. Affected by water erosion, falling debris, moisture and production operation, the shaft wall, tank beam and other facilities of the shaft have safety hazards. Mine hoisting equipment is the "throat" connecting the mine shaft and the underground, and is responsible for the transportation of mineral resources, personnel and materials. The heavy-loaded lifting container runs quickly in the shaft, and it is very important to ensure its safe operation. Therefore, a special time (usually 2 hours) should be arranged every day for shaft inspection. At present, the monitoring of the shaft status is usually carried out by installing a motion camera in the shaft to take a 360-degree picture of the shaft. By comparing and analyzing the captured images, it is observed whether the shaft is deformed or seeping, whether the derrick is deformed, the bolts fall off, and whether the lifting container is skewed, so as to facilitate the monitoring of abnormal conditions. However, since the camera can only take pictures of the status of the wellbore, when cracks are found in the wellbore, the cracks cannot be repaired in time, and subsequent processing by manual or mechanical means is required, which increases processing time and cost. Emergency situations are not handled quickly enough, and defects such as wellbore cracks may affect the stability of the wellbore and even cause safety accidents, posing a high safety risk.

[0003] Therefore, a wellbore status monitoring device has been developed that can move to the wellbore cracks to repair the cracks, save processing time and cost, and improve the stability of the wellbore. Summary of the invention

[0004] In order to overcome the shortcomings that the camera can only take pictures of the wellbore status, when cracks are found in the wellbore, the cracks cannot be repaired in time, and manual or mechanical follow-up processing is required, which increases processing time and cost, and the processing of emergency situations is not fast enough. Defects such as wellbore cracks may affect the stability of the wellbore and even cause safety accidents, posing a high safety risk, the present invention provides a wellbore status monitoring device that can move to the wellbore cracks to repair the cracks, saves processing time and cost, and improves the stability of the wellbore.

[0005] A wellbore status monitoring device includes a mounting frame, fixing bolts, a detection mechanism and a repair mechanism. There are four mounting frames, and two adjacent mounting frames are detachably connected via a plurality of fixing bolts. The mounting frame is provided with a detection mechanism capable of monitoring the wellbore status, and the detection mechanism is provided with a repair mechanism capable of repairing wellbore cracks.

[0006] Further explanation, the detection mechanism includes a connecting block, a driving motor, a friction wheel, a camera, a fixed frame, a telescopic rod, a first pressure spring, a top frame, a dual-axis motor and a moving wheel. The mounting frame is slidably connected to the connecting block, the inner side of the lower part of the connecting block is connected to the driving motor, the friction wheel is connected to the output shaft of the driving motor, the friction wheel is in contact with the mounting frame, the upper side of the connecting block is connected to the camera through a damping rotation, the outer side of the mounting frame is connected to the fixed frame, the fixed frame is connected to a plurality of telescopic rods, the top frame is connected between the telescopic ends of two adjacent telescopic rods, the top frame is connected to the first pressure spring between the connected telescopic rods, the top frame is connected to the dual-axis motor, the output shaft of the dual-axis motor is connected to the moving wheel, the top frame on the telescopic rod is brought close to the inner wall of the wellbore by the action of the first pressure spring, so that the moving wheel contacts the inner wall of the wellbore, and then the dual-axis motor is started to drive the moving wheel to rotate, so that the device moves in the wellbore, and after moving to the detection position, the driving motor is started to drive the friction wheel to rotate, so that the connecting block moves along the mounting frame, drives the camera to move, and performs 360° monitoring of the inner wall of the wellbore.

[0007] Further description, anti-skid grooves are provided on the moving wheels.

[0008] Further explanation, the repair mechanism includes a support frame, a storage box, an electric push rod, a fixed block, a discharge nozzle, a discharge pump and a feeding pipe. The support frame is connected to the inner side of the upper part of the connecting block, and the storage box is clamped on the support frame. The electric push rod is connected to the right side of the connecting block, and the fixed block is connected to the telescopic end of the electric push rod. The discharge nozzle is connected to the fixed block, and the upper right side of the storage box is connected to the discharge pump. The upper side of the discharge pump is connected to the feeding pipe, and the feeding pipe is connected to the discharge nozzle. When the camera detects cracks on the inner wall of the wellbore, the support frame is driven to move through the connecting block to move the discharge nozzle to the crack, and then the electric push rod is started to push the fixed block to move so that the discharge nozzle is close to the crack position, and then the discharge pump is started to send the slurry in the storage box from the feeding pipe into the discharge nozzle, so that the discharge nozzle fills the slurry into the crack.

[0009] Further explanation: a grouting pipe is provided on the upper side of the storage box.

[0010] Further description, the discharge nozzle is conical.

[0011] Further description, it also includes a stabilizing mechanism, which includes a first connecting frame, a first rotating plate, a rotating wheel and a first torsion spring. The first connecting frame is connected to the upper and lower sides of the top frame. The first connecting frame is rotatably connected to the first rotating plate. The first rotating plate is rotatably connected to the rotating wheel. The first torsion spring is connected between the first rotating plate and the first connecting frame. When the mounting frame is placed inside the wellbore, the first rotating plate on the first connecting frame is moved close to the inner wall of the wellbore by the action of the first torsion spring, so that the rotating wheel contacts the inner wall of the wellbore. When the mounting frame moves up and down in the wellbore, the rotating wheel rotates and moves along the inner wall of the wellbore.

[0012] Further description, it also includes a flattening mechanism, which includes a second connecting frame, a second rotating plate, a cleaning wheel and a second torsion spring. The second connecting frame is connected to the lower side of the fixed block, the second connecting frame is rotatably connected to the second rotating plate, the second rotating plate is rotatably connected to the cleaning wheel, and the second torsion spring is connected between the second rotating plate and the second connecting frame. When the fixed block approaches the crack in the wellbore, it drives the second connecting frame to move so that the cleaning wheel contacts the inner wall of the wellbore. As the second connecting frame continues to move, the cleaning wheel rotates and moves on the inner wall of the wellbore to clean impurities in the cracks in the wellbore. At this time, the second rotating plate rotates and the second torsion spring is deformed. When the slurry fills the cracks, the fixed block is reset and the second torsion spring is restored, so that the cleaning wheel rotates and moves on the inner wall of the wellbore again to flatten the slurry.

[0013] Further description, it also includes a protection mechanism, which includes a guide plate, a sliding frame, a baffle and a second pressure spring. The upper sides of the left and right parts of the support frame are connected to the front and rear guide plates, and the sliding frame is slidably connected between two adjacent guide plates. The baffle is connected between the upper sides of the sliding frame, and the second pressure spring is connected between the sliding frame and the guide plate connected to the front side. When the mounting frame is placed inside the wellbore, the baffle contacts the inner wall of the wellbore. Through the action of the second pressure spring, the baffle on the sliding frame is always close to the inner wall of the wellbore.

[0014] Further explanation, it also includes a monitoring mechanism, which includes a gas monitor, a humidity sensor and a signal transmitter. The gas monitor is connected to the upper middle side of the support frame, the humidity sensors are connected to the left and right sides of the support frame, and the signal transmitter is connected to the upper middle side of the support frame. The signal transmitter is located on the right side of the gas monitor. The gas monitor and the humidity sensor are connected to the signal transmitter through wires. The gas monitor monitors the gas concentration in the wellbore, and the humidity sensor monitors the humidity in the wellbore. The monitored results are transmitted to the monitoring instrument through the signal transmitter.

[0015] The beneficial effects of the present invention are as follows: 1. When the camera detects cracks on the inner wall of the wellbore, the present invention drives the support frame to move by the connecting block, so that the discharge nozzle moves to the crack, and then the electric push rod is started to push the fixed block to move, so that the discharge nozzle is close to the crack position, and then the discharge pump is started to make the discharge nozzle fill the slurry into the crack, so as to achieve the effect of being able to move to the crack of the wellbore to repair the crack, saving processing time and cost, and improving the stability of the wellbore.

[0016] 2. The present invention starts a dual-axis motor to drive the moving wheel to rotate, so that the device moves in the wellbore. After moving to the detection position, the drive motor is started to drive the friction wheel to rotate, so that the connecting block moves along the mounting frame, driving the camera to move, and the inner wall of the wellbore is monitored 360°, thereby achieving the effect of being able to quickly and conveniently monitor the wellbore status and improving the efficiency of wellbore status monitoring.

[0017] 3. The present invention uses the force of the first torsion spring to make the first rotating plate on the first connecting frame close to the inner wall of the wellbore, so that the rotating wheel contacts the inner wall of the wellbore. While the mounting frame moves up and down in the wellbore, the rotating wheel rotates and moves along the inner wall of the wellbore, thereby achieving the effect of improving the stability of the mounting frame moving in the wellbore.

[0018] 4. The present invention allows the cleaning wheel to rotate and move on the inner wall of the wellbore as the second connecting frame continues to move, thereby cleaning impurities in the cracks of the wellbore. At this time, the second rotating plate rotates and the second torsion spring is deformed. When the slurry fills the cracks, the fixed block is reset and the second torsion spring is restored, so that the cleaning wheel rotates and moves on the inner wall of the wellbore again to flatten the slurry, thereby achieving the effect of improving the repair effect of the cracks and preventing the cracks from breaking again.

[0019] 5. In the present invention, the baffle is located above the camera. When the mounting frame is placed inside the wellbore, the baffle contacts the inner wall of the wellbore. Through the action of the second pressure spring, the baffle on the sliding frame is always in close contact with the inner wall of the wellbore, thereby achieving the effect of protecting the camera and preventing objects from falling from above the wellbore and causing damage to the camera.

[0020] 6. The present invention monitors the gas concentration in the wellbore through a gas monitor, and monitors the humidity in the wellbore through a humidity sensor. The monitored results are transmitted to the monitoring instrument through a signal transmitter, thereby achieving the effect of being able to monitor the environment in the wellbore and improving the accuracy of wellbore status monitoring.

The mounting frame 1 is slidably connected with the connecting block 31, the inner side of the lower part of the connecting block 31 is connected to the driving motor 32, the friction wheel 33 is connected to the output shaft of the driving motor 32, the friction wheel 33 is in contact with the mounting frame 1, and the upper side of the connecting block 31 is connected to the camera 34 through a damping rotation. The outer side of the mounting frame 1 is connected to the fixing frame 35, and the fixing frame 35 is connected to two telescopic rods 36, and the top frame 37 is connected between the telescopic ends of two adjacent telescopic rods 36, and the top frame 37 is connected to the first pressure spring 361 between the connected telescopic rods 36, and the top frame 37 is connected to the dual-axis motor 38, and the moving wheel 39 is connected to the output shaft of the dual-axis motor 38, and the moving wheel 39 is provided with an anti-skid groove to improve the movement stability.

[0038] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the repair mechanism 4 includes a support frame 41, a storage box 42, an electric push rod 43, a fixed block 44, a discharge nozzle 45, a discharge pump 46 and a feeding pipe 47. The support frame 41 is connected to the inner side of the upper part of the connecting block 31, and the storage box 42 is clamped on the support frame 41. A grouting pipe is provided on the upper side of the storage box 42 to facilitate the addition of slurry. An electric push rod 43 is connected to the right side of the connecting block 31, and a fixed block 44 is connected to the telescopic end of the electric push rod 43. The fixed block 44 is connected to the discharge nozzle 45, and the discharge nozzle 45 is conical to facilitate repairing cracks. A discharge pump 46 is connected to the upper side of the right part of the storage box 42, and a feeding pipe 47 is connected to the upper side of the discharge pump 46, and the feeding pipe 47 is connected to the discharge nozzle 45.

[0039] When using the present invention, first, according to the size of the wellbore, a corresponding number of mounting frames 1 are spliced ​​together by fixing bolts 2 to form a circle. After the splicing is completed, the mounting frame 1 is placed inside the wellbore, and the top frame 37 on the telescopic rod 36 is brought close to the inner wall of the wellbore through the action of the first pressure spring 361, so that the moving wheel 39 contacts the inner wall of the wellbore, and then the dual-axis motor 38 is started to drive the moving wheel 39 to rotate, so that the device moves in the wellbore. After moving to the detection position, the drive motor 32 is started to drive the friction wheel 33 to rotate, so that the connecting block 31 moves along the mounting frame 1, and drives the camera 34 to move, so as to monitor the inner wall of the wellbore at 360 degrees, thereby playing a role in quickly and conveniently monitoring the wellbore status and improving the efficiency of wellbore status monitoring. When the camera 34 detects cracks on the inner wall of the wellbore, the friction wheel 33 is driven to rotate by the driving motor 32, so that the connecting block 31 drives the support frame 41 to move, and the discharge nozzle 45 is moved to the crack. The electric push rod 43 is then started to push the fixed block 44 to move, so that the discharge nozzle 45 is close to the crack position, and then the discharge pump 46 is started to feed the slurry in the storage box 42 from the feeding pipe 47 to the discharge nozzle 45, so that the discharge nozzle 45 fills the slurry into the crack, thereby moving to the crack of the wellbore to repair the crack, saving processing time and cost, and improving the stability of the wellbore.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, a stabilizing mechanism 5 is also included, and the stabilizing mechanism 5 includes a first connecting frame 51, a first rotating plate 52, a rotating wheel 53 and a first torsion spring 54. The first connecting frame 51 is connected to the upper and lower sides of the top frame 37, the first connecting frame 51 is rotatably connected to the first rotating plate 52, the first rotating plate 52 is rotatably connected to the rotating wheel 53, and the first rotating plate 52 is connected to the first connecting frame 51 with a first torsion spring 54.

[0041] By using the stabilizing mechanism 5 of the present device, the stability of movement in the wellbore can be improved. When the mounting frame 1 is placed inside the wellbore, the first rotating plate 52 on the first connecting frame 51 is moved close to the inner wall of the wellbore through the force of the first torsion spring 54, so that the rotating wheel 53 contacts the inner wall of the wellbore. While the mounting frame 1 moves up and down in the wellbore, the rotating wheel 53 rotates and moves along the inner wall of the wellbore, thereby improving the stability of the mounting frame 1 in the wellbore.

[0042] like Figure 1 , Figure 2 , Fig. 9 and Fig.10As shown, it also includes a flattening mechanism 6, which includes a second connecting frame 61, a second rotating plate 62, a cleaning wheel 63 and a second torsion spring 64.

[0043] By using the flattening mechanism 6 of the present device, the slurry can be flattened. When the fixed block 44 approaches the crack in the wellbore, it drives the second connecting frame 61 to move, so that the cleaning wheel 63 contacts the inner wall of the wellbore. As the second connecting frame 61 continues to move, the cleaning wheel 63 rotates and moves on the inner wall of the wellbore to clean the impurities in the cracks in the wellbore. At this time, the second rotating plate 62 rotates, and the second torsion spring 64 is deformed. When the slurry fills the crack, the fixed block 44 is reset, and the second torsion spring 64 is restored, so that the cleaning wheel 63 rotates and moves on the inner wall of the wellbore again to flatten the slurry, thereby improving the effect of repairing the cracks and preventing the cracks from breaking again.

The baffle 73 is connected between the upper sides of the sliding frames 72, and the second pressure spring 74 is connected between the sliding frames 72 and the guide plate 71 connected to the front side.

[0045] By using the protection mechanism 7 of the device, the camera 34 can be protected. The baffle 73 is located above the camera 34. When the mounting frame 1 is placed inside the wellbore, the baffle 73 contacts the inner wall of the wellbore. Through the action of the second pressure spring 74, the baffle 73 on the sliding frame 72 is always in close contact with the inner wall of the wellbore, thereby protecting the camera 34 and preventing objects from falling from above the wellbore and causing damage to the camera 34.

[0046] like Figure 1 , Figure 2 and Fig.13As shown, a monitoring mechanism 8 is also included, and the monitoring mechanism 8 includes a gas monitor 81, a humidity sensor 82 and a signal transmitter 83. The gas monitor 81 is connected to the upper middle side of the support frame 41, and the humidity sensor 82 is connected to the left and right sides of the support frame 41. The signal transmitter 83 is connected to the upper middle side of the support frame 41, and the signal transmitter 83 is located on the right side of the gas monitor 81. The gas monitor 81 and the humidity sensor 82 are both connected to the signal transmitter 83 through wires.

[0047] The monitoring mechanism 8 of the device can monitor the environment in the wellbore. The gas monitor 81 monitors the gas concentration in the wellbore, and the humidity sensor 82 monitors the humidity in the wellbore. The monitored results are transmitted to the monitoring instrument through the signal transmitter 83, thereby playing a role in monitoring the environment in the wellbore and improving the accuracy of wellbore status monitoring.
