[0041] Figure 1 A schematic diagram of the overall structure of a cable drilling device according to an embodiment of this application is shown. Figure 1 As shown in the figure, this application provides a cable drilling device, including:

[0042] The fixing mechanism 1 includes two clamping members 11 spaced apart, each clamping member 11 having a cable clamping position, and a slide rail 12 connecting the two clamping members 11.

[0043] Temperature positioning mechanism 2 is slidably mounted on slide rail 12 and includes temperature probe 21, which is used to monitor cable temperature.

[0044] The wave crest identification mechanism 3 is slidably mounted on the slide rail 12 and includes a distance sensor 31. The distance sensor 31 is used to scan the cable 20 within a cable position range determined according to the cable temperature and obtain wave crest height data within the cable position range.

[0045] The drilling mechanism 4 is slidably mounted on the slide rail 12 and includes a drill 41, a drill bit 42 and a controller. The drill bit 42 is connected to the drill 41, and the controller is connected to the drill 41, the temperature probe 21 and the distance sensor 31 respectively.

[0046] Among them, cable 20 is a cable with a metal sheath covering its outer perimeter. The metal sheath can be a corrugated aluminum sheath or other sheaths with uneven outer surfaces.

[0047] The fixing mechanism 1 is used to fix the cable 20, and two clamping members 11 clamp and fix the outer periphery of the cable 20. The temperature positioning mechanism 2, the peak identification mechanism 3, and the drilling mechanism 4 are all slidably mounted on the slide rail 12 between the two clamping members 11, and can move along the slide rail 12. The drilling mechanism 4 is mounted on the fixing mechanism 1 via the slide rail 12, which can ensure that the drill bit 42 is fed axially and drills a hole in the radial direction of the cable 20.

[0048] The controller is the controller for the drilling mechanism 4 and is electrically connected to the drilling rig 41. The controller can control the drill bit 42 to move radially toward the cable 20 to perform drilling. The controller is electrically and / or communicatively connected to the temperature probe 21 and the distance sensor 31. The controller receives cable temperature data monitored by the temperature probe 21 and wave crest height data detected by the distance sensor 31, and locates the drilling position based on the cable temperature data and wave crest height data.

[0049] When the cable drilling equipment is working, the temperature positioning mechanism 2 moves along the slide rail 12 and monitors the cable surface temperature in real time through the temperature probe 21. It locates the highest temperature point (the position with the highest temperature) on the cable surface, thereby initially positioning the drilling position of the cable 20 and obtaining the preliminary positioning position, which is then sent to the controller. The preliminary positioning position is the coordinate of the highest temperature point, and its positioning accuracy can reach ±5mm.

[0050] After receiving the positioning information of the preliminary positioning location, the controller controls the peak identification mechanism 3 to scan the cable 20 within the cable position range centered on the preliminary positioning location, acquiring peak height data within the cable position range. Upon receiving the peak height data, the controller analyzes it, identifies the highest peak (most prominent peak) within the range, and positions it as the final drilling location. The peak height difference identification accuracy (positioning accuracy) is preferably ±0.1mm.

[0051] The controller analyzes the wave crest height data, determines the drilling position, controls the drilling mechanism 4 to move along the slide rail 12 to the drilling position, and controls the drill bit 42 to move in the radial direction of the cable 20 toward the cable 20 to drill.

[0052] The cable drilling equipment provided in this embodiment comprises a fixing mechanism 1, a temperature positioning mechanism 2, a wave crest identification mechanism 3, and a drilling mechanism 4. The fixing mechanism 1 includes two clamping members 11 spaced apart, each clamping member 11 having a cable clamping position, and a slide rail 12 connecting the two clamping members 11. The temperature positioning mechanism 2 is slidably mounted on the slide rail 12 and includes a temperature probe 21 for monitoring cable temperature. The wave crest identification mechanism 3 is slidably mounted on the slide rail 12 and includes a distance sensor 31 for drilling the cable 20 within a cable position range determined according to the cable temperature. The system performs a line scan to obtain the peak height data within the cable's location range. The drilling mechanism 4 is slidably mounted on the slide rail 12 and includes a drill rig 41, a drill bit 42, and a controller. The drill bit 42 is connected to the drill rig 41, and the controller is connected to the drill rig 41, the temperature probe 21, and the distance sensor 31. Through the coordinated work of the temperature probe 21 and the peak identification module, the system can first locate the highest temperature point on the cable surface, and then accurately identify the most prominent peak of the metal sheath within the cable length range where the highest temperature point is located. This solves the problem of drilling position deviation caused by uneven surface of the metal sheath cable and ensures accurate positioning of the drilling position.

[0053] In addition, in this embodiment, the controller on the drilling mechanism 4 is connected to the temperature probe 21 of the temperature positioning mechanism 2 and the ranging sensor 31 of the wave peak recognition mechanism 3, which can realize the full-process automation from temperature positioning, wave peak recognition to drilling, and achieve intelligent and precise positioning.

[0054] In some embodiments, such as Figure 1 As shown, the temperature positioning mechanism 2 also includes a first data processing unit 22, and the peak identification mechanism 3 also includes a second data processing unit 32. The first data processing unit 22 and the second data processing unit 32 are respectively connected to the controller for communication.

[0055] The first data processing unit 22 is also electrically connected to the temperature probe 21. The temperature probe 21 collects cable temperature data in real time and transmits it to the first data processing unit 22. The first data processing unit 22 compares and analyzes the cable temperature data, automatically locates the point with the highest temperature within the coverage area of ​​the cable drilling equipment, and marks its position coordinates to achieve preliminary positioning of the drilling location.

[0056] The second data processing unit 32 is also electrically connected to the ranging sensor 31. The ranging sensor 31 faces the cable surface and scans the cable length range where the highest temperature point marked by the temperature positioning mechanism 2 is located, acquiring the peak height data of the cable 20 within this range, and transmitting it to the second data processing unit 32. The second data processing unit 32 processes the peak height data, identifies the highest peak (most prominent peak) within this range, and positions it as the drilling point (drilling location), achieving precise positioning of the drilling location.

[0057] In the above embodiments, the data is centrally processed by a controller located in the drilling mechanism 4. In this embodiment, by setting a first data processing unit 22 and a second data processing unit 32 in the temperature positioning mechanism 2 and the peak identification mechanism 3 respectively, the monitoring data from different mechanisms are processed in a timely manner, and the inaccurate positioning caused by partial data loss during data transmission can be avoided, thereby improving data processing efficiency and positioning accuracy. The controller only needs to control the drilling mechanism 4 to move to the drilling position to perform drilling based on the positioning result of the second data processing unit 32.

[0058] It is understood that the movement of the temperature positioning mechanism 2, the wave peak identification mechanism 3, and the fixing mechanism 1 along the slide rail 12 can be uniformly controlled by the controller of the drilling mechanism 4, or it can be controlled by their respective control units. For example, the movement of the drilling mechanism 4 is controlled by the controller of the drilling mechanism 4, the movement of the temperature positioning mechanism 2 is controlled by the second data processing unit 32, and the movement of the wave peak identification mechanism 3 is controlled by the second data processing unit 32. Or, for another example, the controller of the drilling mechanism 4 is specifically used to control the operation of the drilling rig 41, the movement of the drilling mechanism 4 along the slide rail 12 is controlled by an independent first control unit, the movement of the temperature positioning mechanism 2 is controlled by an independent second control unit, and the movement of the wave peak identification mechanism 3 is controlled by an independent third control unit. The specific control structure and control method are not specifically limited in this application.

[0059] Preferably, the clamping member 11 is an arc-shaped clamp that can hold the upper and lower surfaces of the cable 20. The inner edge of the arc-shaped clamp is adapted to the shape of the cable 20 to ensure stable and reliable clamping of the cable 20. The clamping member 11 is preferably made of high-strength aluminum alloy. The overall length of the fixing mechanism 1 is preferably 1 to 2 m to meet the drilling requirements of cables 20 of different lengths.

[0060] In some embodiments, the inner surface of the clamping member 11 is provided with an anti-slip pad layer connected to the metal sheath.

[0061] An anti-slip pad is attached to the inner surface of the clamping member 11 to increase friction and prevent the cable 20 or the clamping member 11 from sliding during operation. The anti-slip pad is preferably made of silicone and has a thickness of 2mm.

[0062] In some embodiments, such as Figure 1 As shown, the clamping member 11 is also provided with an adjusting bolt 13.

[0063] Adjusting bolts 13 can be symmetrically distributed at the upper and lower ends of the clamping member 11. By tightening the adjusting bolts 13, the clamping member 11 and the cable 20 can be securely connected. It can also meet the drilling requirements of cables 20 with different diameters, has strong adaptability, and is easy to install and disassemble, making it suitable for on-site working environments.

[0064] In practice, the clamping member 11 can be an elastic clamping member, which can fix the cable 20 without the need for adjusting bolts 13, and can meet the drilling requirements of cables of different diameters.

[0065] In some embodiments, such as Figure 1 As shown, there are multiple temperature probes 21, which are arranged at intervals along the length of the slide rail 12.

[0066] Multiple temperature probes 21 (e.g., three in this embodiment) are arranged sequentially at intervals (e.g., evenly distributed) along the length of the slide rail 12 to accurately detect the cable temperature. The detection range of the temperature probes 21 is preferably 0℃ to 90℃, with an accuracy of ±0.5℃. The detection end of the temperature probe 21 is in contact with the cable surface to achieve accurate temperature detection. The temperature probes 21 can also be arranged in multiple rows and columns to form a temperature probe array.

[0067] In some embodiments, the cable location range detected by the ranging sensor 31 includes a cable length range with a diameter of 8 to 12 cm centered on the initial positioning position, in order to obtain peak height data with high positioning correlation. Data from distant locations can be ignored, improving positioning accuracy while reducing data processing volume. For example, a cable area with a diameter of 10 cm centered on the initial positioning position.

[0068] In some embodiments, such as Figure 2 As shown, the drilling mechanism 4 also includes a displacement sensor 43 and a torque sensor 44. The displacement sensor 43 and the torque sensor 44 are respectively connected to the controller. The displacement sensor 43 is installed on one side of the drill bit 42 and is used to detect the feed depth of the drill bit 42. The torque sensor 44 is installed between the drilling machine 41 and the drill bit 42 and is used to detect the torque of the drill bit 42.

[0069] The output shafts of the drill bit 42 and the drilling rig 41 can be connected by a coupling. The displacement sensor 43 is installed on one side of the drill bit 42 and can monitor the feed depth of the drill bit 42 in real time. The torque sensor 44 is installed between the drill bit 42 and the output shaft of the drilling rig 41, for example, it can be integrated into the coupling to collect the torque value of the drill bit 42 in real time.

[0070] After the central axis of drill bit 42 is aligned with the positioned borehole, the controller controls the drilling rig 41 to operate. Drill bit 42 feeds towards cable 20. Displacement sensor 43 monitors the feed depth of drill bit 42 in real time, triggering a torque detection every time a preset feed depth (e.g., 1 mm) is reached. Torque sensor 44 collects the torque value of drill bit 42 based on the displacement signal from displacement sensor 43, determining whether drill bit 42 has penetrated the metal sheath. When the torque value is 0, it is determined that drill bit 42 has penetrated the metal sheath, and the recorded feed depth at this time is the thickness of the metal sheath.

[0071] Traditional drilling methods rely on torque feedback, lacking closed-loop control during feed. If a sudden torque change is detected, the drill bit continues to advance, easily damaging the main insulation of the cable 20. In this embodiment, a closed-loop control of torque and displacement is achieved through the cooperation of displacement sensor 43 and torque sensor 44. The torque sensor monitors the torque of the drill bit 42 in real time at each preset feed depth. Combined with the depth feedback from displacement sensor 43, it can accurately determine whether the drill bit 42 has penetrated the metal sheath, avoiding over-drilling and damage to the internal structure of the cable 20. In other words, this embodiment achieves safe and controllable drilling.

[0072] The displacement sensor 43 is preferably a grating ruler, and its detection accuracy is preferably ±0.1mm.

[0073] In some embodiments, such as Figure 1 As shown, the drilling mechanism 4 is equipped with a display screen 45, which is connected to the controller and is used to display drilling-related information.

[0074] Drilling-related information can include feed depth and torque curves. The feed depth is measured in mm, with a preferred accuracy of 0.1 mm. The torque curve can be a torque-depth curve showing the change in torque with depth. Drilling-related information can also include drilling results. For example, when the drill bit 42 penetrates the metal sheath, the display screen 45 can simultaneously display a message such as "Drilled through" or "Metal sheath penetrated".

[0075] In this embodiment, by setting up a display screen 45, the feed depth and torque curves are visualized, which makes it easier for operators to control the drilling process in real time and achieve safe and controllable drilling.

[0076] The display screen 45 can also mark and display positioning information such as the location of the highest temperature point (preliminary positioning position) and the drilling position, or temperature data.

[0077] The display screen 45 is preferably a touch screen, which can display drilling-related information and perform operations to achieve drilling control.

[0078] In some embodiments, the drill bit 42 is a hollow drill bit, which contains a gas detection device.

[0079] The hollow drill bit has a built-in gas detection device. After the drill bit 42 penetrates the metal sheath, it can directly detect the pressure and humidity of the gas inside the cable 20 without the need for additional equipment disassembly or tool replacement. This simplifies the cable testing process, improves work efficiency, and enables integrated testing of the cable 20. The hollow drill bit is preferably made of high-speed steel, with an outer diameter of 3-5 mm and an inner diameter of 2 mm.

[0080] As can be seen from the above, the cable drilling equipment provided in this application embodiment can realize full-process automation from temperature positioning and peak identification to borehole monitoring and gas detection, reduce human judgment errors, lower the skill requirements of operators, and improve operational safety and consistency.

[0081] The specific working process of cable drilling equipment is as follows:

[0082] (1) Cable fixing: The cable 20 is clamped by the clamping part 11 of the fixing mechanism 1 and the adjusting bolt 13 is tightened so that the anti-slip pad of the clamping part 11 is in close contact with the cable surface, ensuring the stable fixing of the cable 20.

[0083] (2) Temperature detection and preliminary positioning: The temperature positioning mechanism 2 starts working and collects cable temperature data on the surface of the cable through the temperature probe 21. The controller (or the first data processing unit 22) of the drilling mechanism 4 compares and analyzes the cable temperature data, determines the preliminary positioning position based on the position of the highest temperature point, and marks and displays the preliminary positioning position on the display screen 45 (for example, displaying "35cm away from the left end of the equipment").

[0084] (3) Peak identification and positioning accuracy: The peak identification mechanism 3 starts working and uses the distance sensor 31 to perform a circumferential scan of the cable length range where the highest temperature point is located (e.g., within 10cm around the highest temperature point) to obtain peak height data; the controller (or the second data processing unit 32) of the drilling mechanism 4 processes the peak height data, identifies the most prominent peak in the range, positions its center as the drilling position, and controls the drill rig 41 to move along the slide rail 12 to directly above the drilling position.

[0085] (4) Precision drilling: The drill rig 41 is started (e.g., the speed is set to 500 r / min), and the drill bit 42 begins to feed toward the drilling position of the cable 20; the displacement sensor 43 monitors the feed depth in real time. Every time the drill bit 42 feeds to a preset depth (e.g., 1 mm), the torque sensor 44 is triggered to detect the torque value of the drill bit 42 and transmits the data to the display screen 45 for display. The display screen 45 updates the feed depth and torque curve in real time; when the torque value suddenly changes to 0, the display screen 45 prompts "the metal sheath has been drilled through", and the feed depth (i.e. the thickness of the metal sheath) is recorded at this time.

[0086] Example 2

[0087] Figure 3 A flowchart illustrating a cable drilling method according to an embodiment of this application is shown. Figure 3 As shown in the figure, this application provides a cable drilling method, the method comprising:

[0088] S101: Control the temperature positioning mechanism 2 to move along the slide rail 12 of the fixed mechanism 1, and monitor the cable temperature through the temperature probe 21 set in the temperature positioning mechanism 2;

[0089] S102: The preliminary positioning position is obtained by initially locating the drilling position of the cable 20 based on the cable temperature;

[0090] S103: The distance sensor 31 installed in the wave crest identification mechanism 3 scans the cable 20 within the cable position range where the initial positioning position is located, and obtains the wave crest height data within the cable position range.

[0091] S104: Determine the drilling location based on the crest height data;

[0092] S105: Control the drilling mechanism 4 to move to the drilling position, and control the drill bit 42 to feed toward the drilling position to perform drilling.

[0093] Temperature positioning mechanism 2 starts working first, collecting cable temperature data on the cable surface through temperature probe 21. The controller of drilling mechanism 4 compares and analyzes the cable temperature data, and performs preliminary positioning of the drilling position based on the location of the highest temperature point, thus obtaining the preliminary positioning position. Wave crest identification mechanism 3 starts working, scanning the cable length range where the preliminary positioning position is located through distance sensor 31 to obtain wave crest height data. The controller of drilling mechanism 4 processes the wave crest height data, identifies the most prominent wave crest within the range, and positions its center as the drilling position. Drilling mechanism 4 starts moving to the drilling position, and the controller of drilling mechanism 4 starts drilling machine 41, controlling drill bit 42 to feed towards the drilling position of cable 20 to drill.

[0094] In some embodiments, the method further includes:

[0095] S201: The feed depth of the drill bit 42 is detected by the displacement sensor 43 installed on the drilling mechanism 4;

[0096] S202: Based on the feed depth detected by the displacement sensor 43, the torque sensor 44 installed on the drilling mechanism 4 detects the torque of the drill bit 42;

[0097] S203: Determine whether drilling is complete based on the torque of drill bit 42.

[0098] During the drilling process, the displacement sensor 43 monitors the feed depth in real time. Every time the drill bit 42 feeds to a preset depth (e.g., 1 mm), the torque sensor 44 is triggered to detect the torque value of the drill bit 42. When the torque value suddenly drops to 0, the drilling is considered complete. At this time, the drill bit 42 drills through the metal sheath of the cable 20, and the feed depth of the drill bit 42 is the thickness of the metal sheath.
