Abstract
Description
Technical Field
[0001] The present application relates to the technical field of ultra-high voltage transmission circuit detection, and in particular to detection equipment for transmission cable connection fittings and an unmanned aerial vehicle detection system. Background Art
[0002] In the power system, ultra-high (UHV) transmission lines undertake the important task of long-distance, large-capacity power transmission. To ensure the stable operation of the transmission lines, the internal quality of connection fittings such as tension clamps and linear joint pipes is crucial. Therefore, regular internal quality inspection of connection fittings has become a key part of power operation and maintenance.
[0003] Traditional inspection methods are mainly achieved through X-ray flaw detection technology to evaluate whether the hardware has cracks, corrosion or other defects that may affect its structural integrity. However, X-ray flaw detection equipment is usually large and bulky, which greatly limits its application in field high-altitude operations. When using manual inspection methods, inspectors need to climb to the top of the line and transfer the X-ray flaw detection equipment to the work point through pulleys and other means, which makes the operation difficult and inefficient. In addition, long-term close contact with X-ray equipment poses a serious threat to the health of inspectors and also increases the risk of high-altitude operations.
[0004] The existing detection is assisted by line robots or drones. However, since the ultra-high (extra) high voltage transmission line conductors generally adopt a 6-split or 8-split structure, it is difficult for the robot to be successfully installed on each phase conductor for operation without human assistance. Especially in complex multi-split conductor structures, it is difficult for drones to enter the inside of the conductor, especially the lower conductor, and the receiving end of the X-ray flaw detection equipment cannot avoid the symmetrical conductors, resulting in the inability to meet the all-round flaw detection needs of hardware.
[0005] In summary, the existing X-ray flaw detection methods have problems such as high difficulty, low efficiency, limited detection range and high risk of high-altitude operations in the internal quality inspection of ultra-high voltage (UHV) transmission line connection fittings.

[0043] Referring to Fig. 1, Fig. 1 shows a schematic diagram of the structure of a detection device for connecting a power transmission cable 7 to a fitting 71 in an embodiment of the present application. A detection device for connecting a power transmission cable 7 to a fitting 71 in an embodiment of the present application comprises a frame 1, an X-ray imaging component 2, an imaging plate component 3 and a driving component 4.
[0044] Specifically, the X-ray imaging assembly 2 is disposed in the frame 1 and is configured to be able to be lifted and lowered in the longitudinal direction. The imaging plate assembly 3 is disposed outside the frame 1 and is arranged parallel to the X-ray imaging assembly 2, and the imaging plate assembly 3 is configured to be able to be lifted and lowered in the longitudinal direction. The driving assembly 4 is disposed below the frame 1, and includes a transverse driving portion 41 and a longitudinal driving portion 42, wherein the transverse driving portion 41 can be overlapped above the cable 7, and the longitudinal driving portion 42 can be overlapped on the outside of the cable 7. When the transverse driving portion 41 and the longitudinal driving portion 42 move synchronously along the cable 7, the X-ray imaging assembly 2 and the imaging plate assembly 3 can move downward to the connection fitting 71 to be detected, so as to be able to image and detect the connection fitting 71 to be detected.
[0045] In the specific implementation process, the transverse driving unit 41 and the longitudinal driving unit 42 are first overlapped on the upper and outer sides of the cable 7, respectively. Then the transverse driving unit 41 and the longitudinal driving unit 42 are driven to move synchronously along the cable 7, and the X-ray imaging component 2 and the imaging plate component 3 move downward to the connection fitting 71 to be detected. At this time, the X-ray imaging component 2 emits X-rays, which penetrate the connection fitting 71 and are received by the imaging plate component 3 to form clear image information. By analyzing the image through the image processing system, it can be determined whether the connection fitting 71 has defects.
[0046] In one embodiment, the frame 1 is the supporting structure of the entire device, and is made of high-strength, lightweight materials to ensure the stability and portability of the device. The frame 1 also includes a hood shell, which is arranged outside the frame 1 and plays a role in protecting the internal functional components.
[0047] In one embodiment, the driving assembly 4 is disposed below the frame 1, and includes a transverse driving portion 41 and a longitudinal driving portion 42. The transverse driving portion 41 is laterally overlapped above the cable 7, and rolls on the surface of the cable 7 to move along the upper surface of the cable 7. The longitudinal driving portion 42 is vertically overlapped on the outer side of the cable 7 to move along the outer side surface of the cable 7 in the longitudinal direction.
[0048] As described above, by adopting the transversely and longitudinally arranged driving components 4, the movement of the detection equipment on the power transmission cable 7 is realized, and the contact area with the cable 7 is increased. At the same time, the longitudinal driving part 42 can cooperate with the transverse driving part 41 to increase the stability of the movement, so as to facilitate the detection of the connecting hardware 71 by the detection equipment, thereby improving the reliability of the detection equipment.
[0049] As shown in Figures 2 and 3, Figures 2 and 3 are a schematic diagram of the structure and a partially enlarged schematic diagram of a detection device for connecting a hardware 71 of a power transmission cable 7 provided in an embodiment of the present application. In some embodiments, the detection device further includes a clamping assembly 5, which is disposed below the frame 1, moves synchronously with the driving assembly 4 and can be clamped on the inner side of the cable 7.
[0050] Specifically, the clamping assembly 5 includes a movable first clamping portion 51 and a second clamping portion 52, which are respectively arranged longitudinally on the opposite side of the longitudinal driving portion 42, and there is a certain distance between the first clamping portion 51 and the second clamping portion 52, and the cable 7 is arranged in the distance. The first clamping portion 51 and the second clamping portion 52 move inwardly to clamp the inner side of the cable 7, so that the longitudinal driving portion 42 will not shake or displace when moving along the outer surface of the cable 7, avoiding swing or offset, effectively solving the problem of yaw, improving the stability during movement, and avoiding the detection error caused by the shaking or displacement of the cable 7, ensuring the accuracy and reliability of the detection result.
[0051] In conjunction with Figure 4, Figure 4 is a partial enlarged schematic diagram of the structure of the detection device of the power transmission cable 7 connection fitting 71 provided in an embodiment of the present application. In some embodiments, the lateral drive unit 41 includes a first lateral drive wheel 410, a second lateral drive wheel 411 and a lateral drive motor 412 arranged in parallel.
[0052] Specifically, the transverse driving motor 412 serves as a power source, and its output end is connected to the first transverse driving wheel 410 to provide power for the entire transverse driving unit 41 .
[0053] Furthermore, the first transverse driving wheel 410 includes a first transverse main driving wheel and a first transverse slave driving wheel, both of which are arranged horizontally. The first transverse main driving wheel is directly connected to the output end of the transverse driving motor 412, and the first transverse slave driving wheel is connected to the first transverse main driving wheel to achieve synchronous rotation. The first transverse main driving wheel is overlapped on the upper surface of the cable 7 on one side, and the first transverse slave driving wheel is overlapped on the upper surface of the cable 7 on the other side. Through the extended transverse driving part 41, the transverse driving part 41 can be overlapped on two cables 7 with different numbers of splits at the same time, ensuring the stable support and smooth operation of the detection equipment on the cable 7.
[0054] Furthermore, the structure of the second transverse driving wheel 411 is similar to that of the first transverse driving wheel 410, and also includes a second transverse main driving wheel and a second transverse slave driving wheel. However, unlike the first transverse driving wheel 410, the second transverse main driving wheel is not directly connected to the output end of the transverse driving motor 412, but realizes synchronous rotation with the first transverse main driving wheel through a transverse synchronous belt 413. The second transverse slave driving wheel is connected to the second transverse main driving wheel to realize synchronous rotation. The second transverse main driving wheel and the second transverse slave driving wheel are also overlapped on the upper surfaces of the two cables 7 respectively, and together with the first transverse driving wheel 410, they support the detection device and guide it to move along the cable 7 to improve stability.
[0055] Furthermore, the synchronous belt tensioning wheel 414 is arranged between the first transverse main driving wheel and the second transverse main driving wheel, and is used to adjust the tension of the transverse synchronous belt 413 to ensure the stability and reliability of the transverse synchronous belt 413 during the transmission process.
[0056] In conjunction with Figure 4, Figure 4 is a partial enlarged schematic diagram of the structure of the detection device for connecting the hardware 71 of the power transmission cable 7 provided in an embodiment of the present application. In some embodiments, the longitudinal drive unit 42 includes a first longitudinal drive wheel 420, a second longitudinal drive wheel 421 and a longitudinal drive motor 422 arranged in parallel.
[0057] Specifically, the longitudinal driving motor 422 serves as a power source for longitudinal movement, and its output end is directly connected to the first longitudinal driving wheel 420 to drive the first longitudinal driving wheel 420 to rotate.
[0058] Furthermore, the first longitudinal driving wheel 420 and the second longitudinal driving wheel 421 are configured as roller structures in contact with the outer surface of the cable 7, and are used to support and drive the device to move along the cable 7. The first longitudinal driving wheel 420 and the second longitudinal driving wheel 421 are arranged in parallel, and form an L-shaped structure with the first transverse driving wheel 410 and the second transverse driving wheel 411, respectively, to increase the contact area with the surface of the cable 7, improve the friction, avoid slipping or idling during movement, ensure the stability and balance of the detection device moving on the cable 7, and also ensure the flexible movement of the device on the complex cable 7 line.
[0059] Furthermore, the first longitudinal driving wheel 420 and the second longitudinal driving wheel 421 are connected by a longitudinal synchronous belt 423 to achieve synchronous rotation between the two. The longitudinal synchronous belt 423 has sufficient strength and wear resistance, and can maintain stable transmission performance during long-term use. By adjusting the tension of the longitudinal synchronous belt 423, synchronization and stability during movement are ensured.
[0060] In conjunction with Figures 3 and 4, Figures 3 and 4 are partial enlarged schematic diagrams of the structure of the detection device of the power transmission cable 7 connection fitting 71 provided in an embodiment of the present application. In some embodiments, the first clamping portion 51 includes a first clamping wheel 510, a first fixing block 511, a first guide rail 512, a first transmission screw 513 and a first clamping motor 514.
[0061] Specifically, the first clamping wheel 510 is configured as a roller structure that contacts the surface of the cable 7, and is used to clamp the cable 7 during the movement of the device to prevent the device from slipping or shaking. The first clamping wheel 510 is longitudinally installed below the first fixing block 511, and there is an appropriate spacing between the first longitudinal driving wheel 420 to ensure that the cable 7 can be set within the spacing, so that the first clamping wheel 510 and the first longitudinal driving wheel 420 abut against the surface of the cable 7 without interfering with the movement of the first longitudinal driving wheel 420.
[0062] Furthermore, the first fixing block 511 is used to fix and support the first clamping wheel 510 and serves as a transmission component of the first transmission screw 513. The first fixing block 511 is connected to the first transmission screw 513, and the first fixing block 511 is slidably matched with the first guide rail 512 to reduce friction and resistance during movement.
[0063] Furthermore, the first transmission lead screw 513 is used as a transmission component, and its rotational motion is converted into the linear motion of the first fixed block 511 through a thread. The first clamping motor 514 provides a power source for the first clamping part 51, and its output end is connected to the first transmission lead screw 513. By controlling the rotation direction of the first clamping motor 514, the reciprocating movement of the first clamping wheel 510 can be achieved, which is used to adjust the spacing between the first clamping wheel 510 and the first longitudinal driving wheel 420, so as to adapt to cables 7 of different diameters, ensure the stability of movement, and improve the application range of the detection equipment.
[0064] In one embodiment, the second clamping portion 52 includes a second clamping wheel 520 , a second fixing block 521 , a second guide rail 522 , a second transmission screw 523 and a second clamping motor 524 .
[0065] Specifically, the structure of the second clamping part 52 is similar to that of the first clamping part 51. The second clamping wheel 520 is longitudinally installed below the second fixed block 521, and there is an appropriate spacing between the second clamping wheel 520 and the second longitudinal driving wheel 421. The second fixed block 521 is connected to the second transmission screw 523 by threads, and slides on the second guide rail 522. One end of the second transmission screw 523 is connected to the output end of the second clamping motor 524. By controlling the rotation direction of the second clamping motor 524, the reciprocating movement of the second clamping wheel 520 can be achieved, which is used to adjust the spacing between the second clamping wheel 520 and the second longitudinal driving wheel 421, and can adapt to power transmission cables 7 of different diameters and specifications, thereby improving the scope of application of the detection equipment. During the movement of the equipment, the first clamping wheel 510 and the second clamping wheel 520 maintain contact with the surface of the cable 7, providing the necessary friction to prevent the equipment from slipping or shaking.
[0066] Furthermore, the first clamping portion 51 and the second clamping portion 52 are also provided with limit switches, and the movement distance of the first clamping wheel 510 and the second clamping wheel 520 is controlled by the limit switches, so as to control the distance between the first clamping wheel 510, the second clamping wheel 520 and the first longitudinal driving wheel 420 and the second longitudinal driving wheel 421.
[0067] 5 and 6 are schematic diagrams of the structure of the X-ray imaging assembly 2 and the imaging plate assembly 3 provided in an embodiment of the present application. In some embodiments, the frame 1 includes a cross arm 11 for mounting the imaging plate 31.
[0068] Specifically, at the top of the frame 1, an imaging board 31 mounting cross arm 11 is disposed transversely. The imaging board 31 mounting cross arm 11 is made of high-strength alloy material to ensure that it can bear the weight of the imaging board assembly 3. The imaging board 31 mounting cross arm 11 is disposed to extend transversely, and its extended end protrudes from the main part of the frame 1, providing sufficient space to install and operate the imaging board assembly 3 while avoiding interference with other parts of the frame 1.
[0069] In one embodiment, the imaging plate assembly 3 includes an imaging plate 31 , a hoisting drive belt 32 , a drive belt reel wheel 33 , and an imaging plate lifting drive motor 34 .
[0070] Specifically, the hoisting drive belt 32 is made of a high-strength, wear-resistant synthetic material with good flexibility and load-bearing capacity. One end of the hoisting drive belt 32 is firmly sleeved on the drive belt reel 33, and the other end is fixedly connected to the top of the imaging board 31, so as to realize the vertical lifting movement of the imaging board 31. The drive belt reel 33 is installed on one side of the imaging board 31 mounting cross arm 11, and is directly connected to the output end of the imaging board lifting drive motor 34. The drive belt reel 33 is rotated to roll up or release the hoisting drive belt 32, thereby controlling the lifting height of the imaging board 31.
[0071] Furthermore, the imaging board lifting drive motor 34 uses a high-performance, low-noise DC motor or servo motor, which is installed on the other side of the imaging board 31 mounting cross arm 11. The imaging board lifting drive motor 34 is connected to the drive belt winding wheel 33, and can accurately control the rotation direction and speed of the drive belt winding wheel 33, thereby realizing the smooth lifting of the imaging board 31, so that the imaging board 31 can be moved to the hardware 71 to be detected at different heights, realize the imaging detection process, meet all-round detection needs, and improve adaptability.
[0072] In one embodiment, the X-ray imaging assembly 2 includes an X-ray lifting drive motor 21, an X-ray imaging camera 22, an X-ray hoisting drive belt 23, and a fixing frame 24.
[0073] Specifically, the X-ray lifting drive motor 21 is arranged on the frame 1, as one of the main power sources of the X-ray imaging assembly 2, and is used to drive the X-ray imaging camera 22 and its fixing frame 24 to move up and down in the vertical direction. By controlling the forward and reverse rotation of the motor, the X-ray imaging camera 22 can be imaged at different heights to meet the detection requirements of the cable 7 connection fittings 71 at different positions.
[0074] Furthermore, the X-ray imaging camera 22 is rotatably disposed on the fixed frame 24, and is used to take X-ray photos of the cable 7 connecting the hardware 71. It is equipped with a high-resolution X-ray detector inside, which can capture the fine structure inside the hardware 71, thereby achieving an accurate assessment of the connection quality of the hardware 71.
[0075] Furthermore, one end of the X-ray hoisting drive belt 23 is connected to the X-ray lifting drive motor 21, and the other end is connected to the fixed frame 24. When the X-ray lifting drive motor 21 is working, the X-ray hoisting drive belt 23 will be tightened or loosened accordingly, thereby driving the fixed frame 24 and the X-ray imaging camera 22 thereon to move in the vertical direction. This design not only simplifies the structure of the lifting mechanism, but also improves the stability and reliability of the lifting movement.
[0076] In one embodiment, the X-ray lifting drive motor 21 is arranged on the frame 1, the X-ray imaging camera 22 is rotatably arranged on the fixed frame 24, and one end of the X-ray lifting drive belt 23 is connected to the X-ray lifting drive motor 21, and the other end is connected to the fixed frame 24.
[0077] Specifically, in order to increase the flexibility of the X-ray imaging camera 22, a rotary drive motor 25 and a driving rod 26 are additionally provided. The output end of the rotary drive motor 25 is connected to the driving rod 26, and the driving rod 26 is connected to the X-ray imaging camera 22. When the rotary drive motor 25 is working, it will drive the driving rod 26 and the X-ray imaging camera 22 to rotate together, thereby realizing the rotation of the camera in the horizontal direction, realizing the overall angle adjustment, so that the X-ray imaging camera 22 can capture the cable 7 connection fittings 71 in a larger range, thereby improving the comprehensiveness and accuracy of the detection.
[0078] As shown in Figure 7, Figure 7 is a schematic diagram of the structure of the guide assembly 6 provided in an embodiment of the present application. In some embodiments, the detection device further includes a guide assembly 6 disposed below the frame 1.
[0079] Specifically, the guide assembly 6 is composed of a first guide frame 61 and a second guide frame 62, and an N-shaped structure is formed between the two. This structural design helps to enhance the overall stability of the guide assembly 6, and also enables the guide assembly 6 to guide the detection equipment to land on the power transmission cable 7 quickly and accurately, shortening the detection time, thereby improving the detection efficiency.
[0080] Furthermore, the first guide frame 61 includes a first section 610 and a second section 611. One end of the first section 610 is connected to the bottom of the frame 1, and one end of the second section 611 is connected to the bottom of the frame 1. The connection between the second section 611 and the first section 610 forms a certain arc. The design of this arc enables the guide assembly 6 to fall accurately between the two cables 7, ensuring the rapid installation of the detection equipment.
[0081] Furthermore, one end of the second guide frame 62 is set on the frame 1, and together with the first guide frame 61 constitutes a part of the N-type structure. The other end of the second guide frame 62 is inclined toward the outside of the frame 1. This inclined design makes it easier for the detection equipment to move or adjust its position with the help of the guiding effect of the second guide frame 62 when it needs to be moved or adjusted.
[0082] As shown in Figure 8, Figure 8 is a schematic diagram of the structure of a drone 8 detection system provided in an embodiment of the present application. In some embodiments, a drone 8 detection system is also provided, including a detection device for the power transmission cable 7 connection fittings 71 as described above, and the two are combined to form an efficient and flexible power inspection system.
[0083] In one embodiment, the frame 1 includes a drone hanging ring 12 , and the drone hanging ring 12 is arranged on the top of the frame 1 .
[0084] In one embodiment, the drone 8 detection system includes: a drone 8 and a drone mounting and disassembly component 81 , which is used to be connected to the drone mounting and disassembly component 81 .
[0085] In one embodiment, the drone mounting and dismounting assembly 81 includes a mounting and dismounting ring 810 , a hook 811 and a wind-fixing wing plate 812 .
[0086] Specifically, the hanging and disassembly ring 810 is connected to the drone 8 through a movable lock buckle 813, and its material is a flexible traction rope with good flexibility and durability. The flexible traction rope can move up and down to achieve a self-balancing effect, so that the hanging and disassembly ring 810 can easily adapt to various complex environments while ensuring the safety and reliability of the connection.
[0087] Furthermore, the hook 811 is arranged on the hanging and disassembling ring 810, and is used to connect with the drone hanging ring 12 on the top of the frame 1. When the drone 8 is hovering at a designated position, the operator can use remote control to quickly and accurately dock the hook 811 with the drone hanging ring 12, thereby stably hanging the detection device under the drone 8.
[0088] Furthermore, the wind-fixing wing plate 812 is arranged on the hanging and disassembling ring 810, and the wind-fixing wing plate 812 is provided with a wind guide hole 814 to reduce wind resistance and airflow interference, so that the wind-fixing wing plate 812 always maintains a good posture, thereby suppressing the yaw and sway of the drone hanging and disassembling assembly 81 during high-altitude operation, and improving the stability and safety of the drone 8 during flight. At the same time, the wind-fixing wing plate 812 can also protect the hook 811 and the hanging and disassembling ring 810 to a certain extent, preventing the hook 811 and the hanging and disassembling ring 810 from being damaged due to excessive wind force.
[0089] As described above, by carrying the detection equipment on the drone 8, it is possible to quickly reach the vicinity of the power line for inspection, thereby improving the inspection efficiency. X-ray imaging technology can clearly capture the internal structure of the connection fittings 71 of the transmission cable 7, ensuring the accuracy of the detection results. The inspection by the drone 8 avoids the safety risks brought about by manual inspection. The drone mounting and disassembly assembly 81 makes the connection and disassembly between the detection equipment and the drone 8 very simple and quick, thereby improving the flexibility and adaptability of the system.
[0090] In the specific implementation process, first, the operator selects the number of cables 7 to be detected through the control panel, such as 6 or 8 strands, and the control panel automatically pops up the detection operation page of the corresponding number of strands, displaying the position of the cable 7 to be detected. Secondly, the operator clicks the detection button on the operation page, and the control panel sends a signal to the drive component 4 to drive the detection equipment to move, and at the same time controls the imaging plate component 3 and the X-ray imaging component 2 to rise and fall to the first detection position. Then the X-ray imaging component 2 starts to work and performs X-ray detection on the connection fittings 71. The imaging plate component 3 receives the X-ray signal and converts it into an image for the operator to observe and analyze. After completing the detection of the position of a cable 7, the operator clicks the next detection button to control the imaging plate component 3 and the X-ray imaging component 2 to descend to the second detection position, and repeats the above detection steps. After completing the detection of the connection fittings 71 on one side, the drone 8 is used to lift the entire detection equipment device and turn it 180°, and then reinstall it above the transmission cable 7 to be detected on the other side, and the connection fittings 71 on the other side are detected, and the above detection steps are repeated.
