Description

Technical Field

[0001] This application relates to the field of ultra-high voltage power transmission circuit testing technology, and in particular to testing equipment for power transmission cable connection fittings and UAV testing systems. Background Technology

[0002] In power systems, ultra-high voltage (UHV) transmission lines play a crucial role in transmitting large amounts of electrical energy over long distances. To ensure the stable operation of these transmission lines, the internal quality of connecting hardware, such as tension clamps and straight-line couplings, is paramount. Therefore, regularly conducting internal quality inspections of these connecting hardware components is a key aspect of power system operation and maintenance.

[0003] Traditional inspection methods primarily rely on X-ray flaw detection technology to assess the presence of cracks, corrosion, or other defects in hardware that could affect its structural integrity. However, X-ray flaw detection equipment is typically bulky and cumbersome, significantly limiting its application in high-altitude field operations. When using manual inspection methods, personnel must climb to high points along the route and use pulleys or similar means to pass the X-ray equipment to the work site, resulting in high difficulty, low efficiency, and prolonged close contact with X-ray equipment posing a serious threat to the health of the inspectors, while also increasing the risks associated with working at heights.

[0004] Existing methods use line robots or drones for inspection, but because ultra-high voltage (UHV) transmission line conductors generally adopt 6-split or 8-split structures, it is difficult for robots to be successfully installed on each phase conductor without human assistance. Especially in complex multi-split conductor structures, drones have difficulty entering the inside of the conductor, especially the lower conductor. Furthermore, the receiving end of X-ray flaw detection equipment cannot avoid symmetrical conductors, which makes it impossible to meet the requirements for all-round flaw detection of fittings.

[0005] In summary, existing X-ray flaw detection methods for inspecting the internal quality of fittings in ultra-high voltage (UHV) transmission lines suffer from problems such as high operational difficulty, low efficiency, limited inspection range, and high risks associated with working at heights. Summary of the Invention

[0006] Therefore, it is necessary to provide a testing device for power transmission cable connection hardware, which addresses the problems of high operational difficulty, low efficiency, and limited testing range in existing power transmission circuit connection hardware testing methods.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0043] See Figure 1 , Figure 1 A schematic diagram of the structure of a detection device for a power transmission cable 7 connecting fitting 71 according to an embodiment of this application is shown. An embodiment of this application provides a detection device for a power transmission cable 7 connecting fitting 71, comprising a frame 1, an X-ray imaging assembly 2, an imaging plate assembly 3, and a drive assembly 4.

[0044] Specifically, the X-ray imaging component 2 is disposed within the frame 1 and configured to move vertically. The imaging plate assembly 3 is disposed outside the frame 1 and parallel to the X-ray imaging component 2, and is also configured to move vertically. The driving assembly 4 is disposed below the frame 1 and includes a lateral driving part 41 and a longitudinal driving part 42. The lateral driving part 41 can overlap the cable 7, and the longitudinal driving part 42 can overlap the outside of the cable 7. When the lateral driving part 41 and the longitudinal driving part 42 move synchronously along the cable 7, the X-ray imaging component 2 and the imaging plate assembly 3 can move downward to the connection hardware 71 to be inspected, so as to image and inspect the connection hardware 71 to be inspected.

[0045] In the specific implementation process, the lateral drive unit 41 and the longitudinal drive unit 42 are first overlapped above and outside the cable 7, respectively. Then, the lateral drive unit 41 and the longitudinal drive unit 42 are driven to move synchronously along the cable 7, while the X-ray imaging assembly 2 and the imaging plate assembly 3 move downwards to the connecting hardware 71 to be inspected. At this time, the X-ray imaging assembly 2 emits X-rays, which penetrate the connecting hardware 71 and are received by the imaging plate assembly 3, forming clear image information. By analyzing the image through the image processing system, it can be determined whether there are defects in the connecting hardware 71.

[0046] In one embodiment, frame 1 serves as the supporting structure for the entire device, made of high-strength, lightweight materials to ensure the stability and portability of the device. Frame 1 also includes a housing, disposed on the outside of frame 1, to protect the internal functional components.

[0047] In one embodiment, the drive assembly 4 is disposed below the frame 1 and includes a lateral drive portion 41 and a longitudinal drive portion 42. The lateral drive 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 drive portion 42 is vertically overlapped on the outer side of the cable 7 to move along the outer surface of the cable 7 longitudinally.

[0048] As described above, by employing drive components 4 arranged laterally and longitudinally, the detection equipment can move on the power transmission cable 7, increasing the contact area with the cable 7. At the same time, the longitudinal drive unit 42 can cooperate with the lateral drive unit 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] Combination Figure 2 , Figure 3 As shown, Figure 2 , Figure 3This is a schematic diagram and a partially enlarged view of the detection device for the connection fitting 71 of the power transmission cable 7 provided in one embodiment of this application. In some embodiments, the detection device further includes a clamping component 5, which is disposed below the frame 1, moves synchronously with the driving component 4, and can clamp the cable 7 inside.

[0050] Specifically, the clamping assembly 5 includes a movable first clamping part 51 and a second clamping part 52, which are respectively longitudinally arranged on opposite sides of the longitudinal driving part 42, with a certain distance between them. The cable 7 is disposed within the distance. The first clamping part 51 and the second clamping part 52 move inward to clamp the inner side of the cable 7, so that the longitudinal driving part 42 does not shake or shift when moving along the outer surface of the cable 7, avoiding swaying or deviation, effectively solving the swaying problem, improving the stability during movement, and avoiding detection errors caused by the shaking or displacement of the cable 7, ensuring the accuracy and reliability of the detection results.

[0051] Combination Figure 4 As shown, Figure 4 This is a partially enlarged schematic diagram of the structure of the detection device for the power transmission cable 7 connecting fitting 71 provided in one embodiment of this 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 drive motor 412 serves as a power source, and its output end is connected to the first transverse drive wheel 410 to provide power to the entire transverse drive unit 41.

[0053] Furthermore, the first transverse drive wheel 410 includes a first transverse main drive wheel and a first transverse driven wheel, both horizontally arranged. The first transverse main drive wheel is directly connected to the output end of the transverse drive motor 412, and the first transverse driven wheel is connected to the first transverse main drive wheel to achieve synchronous rotation. The first transverse main drive wheel rests on the upper surface of one side of the cable 7, and the first transverse driven wheel rests on the upper surface of the other side of the cable 7. Through the extended transverse drive part 41, the transverse drive part 41 can simultaneously rest on two cables 7 with different numbers of breaks, ensuring stable support and smooth operation of the detection equipment on the cables 7.

[0054] Furthermore, the structure of the second transverse drive wheel 411 is similar to that of the first transverse drive wheel 410, also including a second transverse main drive wheel and a second transverse driven wheel. However, unlike the first transverse drive wheel 410, the second transverse main drive wheel is not directly connected to the output end of the transverse drive motor 412, but achieves synchronous rotation with the first transverse main drive wheel through a transverse synchronous belt 413. The second transverse driven wheel is connected to the second transverse main drive wheel to achieve synchronous rotation. The second transverse main drive wheel and the second transverse driven wheel are also respectively attached to the upper surfaces of the two cables 7, and together with the first transverse drive wheel 410, they support the detection equipment and guide its movement along the cables 7, improving stability.

[0055] Furthermore, the timing belt tensioner 414 is positioned between the first transverse main drive wheel and the second transverse main drive wheel to adjust the tension of the transverse timing belt 413, ensuring the stability and reliability of the transverse timing belt 413 during transmission.

[0056] Combination Figure 4 As shown, Figure 4 This is a partially enlarged schematic diagram of the structure of the detection device for the power transmission cable 7 connecting fitting 71 provided in one embodiment of this 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 drive motor 422 serves as the power source for longitudinal movement, and its output end is directly connected to the first longitudinal drive wheel 420, driving the first longitudinal drive wheel 420 to rotate.

[0058] Furthermore, the first longitudinal drive wheel 420 and the second longitudinal drive wheel 421 are configured as roller structures that contact the outer surface of the cable 7, used to support and drive the equipment to move along the cable 7. The first longitudinal drive wheel 420 and the second longitudinal drive wheel 421 are arranged parallel to each other, and form an L-shaped structure with the first transverse drive wheel 410 and the second transverse drive wheel 411 respectively, increasing the contact area with the surface of the cable 7, improving friction, avoiding slippage or free rotation during movement, ensuring the stability and balance of the detection equipment moving on the cable 7, and also ensuring the flexible movement of the equipment on complex cable lines 7.

[0059] Furthermore, the first longitudinal drive wheel 420 and the second longitudinal drive wheel 421 are connected by a longitudinal synchronous belt 423 to achieve synchronous rotation between them. The longitudinal synchronous belt 423 has sufficient strength and wear resistance to maintain stable transmission performance during long-term use. By adjusting the tension of the longitudinal synchronous belt 423, synchronicity and stability during movement are ensured.

[0060] Combination Figure 3 , Figure 4As shown, Figure 3 , Figure 4 This is a partially enlarged schematic diagram of the structure of the detection device for the power transmission cable 7 connecting fitting 71 provided in one embodiment of this application. In some embodiments, the first clamping part 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, used to clamp the cable 7 during equipment movement to prevent the equipment from slipping or shaking. The first clamping wheel 510 is longitudinally mounted below the first fixing block 511, with an appropriate gap between it and the first longitudinal drive wheel 420, to ensure that the cable 7 can be positioned within the gap, so that the first clamping wheel 510 and the first longitudinal drive wheel 420 abut against the surface of the cable 7 without interfering with the movement of the first longitudinal drive 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 slides with the first guide rail 512 to reduce friction and resistance during movement.

[0063] Furthermore, the first transmission screw 513 serves as a transmission component, its rotational motion being converted into linear motion of the first fixed block 511 via 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 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 distance between the first clamping wheel 510 and the first longitudinal drive wheel 420, so as to accommodate cables 7 of different diameters, ensure smooth movement, and improve the applicability of the testing equipment.

[0064] In one embodiment, the second clamping part 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 mounted below the second fixed block 521, with an appropriate distance between it and the second longitudinal drive wheel 421. The second fixed block 521 is threadedly connected to the second transmission screw 523 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 distance between the second clamping wheel 520 and the second longitudinal drive wheel 421. This allows for the adaptation of power transmission cables 7 of different diameters and specifications, improving the applicability of the testing 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 part 51 and the second clamping part 52 are also provided with limit switches, which control the movement distance of the first clamping wheel 510 and the second clamping wheel 520, so as to control the distance between the first clamping wheel 510, the second clamping wheel 520 and the first longitudinal drive wheel 420 and the second longitudinal drive wheel 421.

[0067] Combination Figure 5 , Figure 6 As shown, Figure 5 , Figure 6 This is a schematic diagram of the structure of the X-ray imaging assembly 2 and the imaging plate assembly 3 provided in one embodiment of this application. In some embodiments, the frame 1 includes an imaging plate 31 with a crossbeam 11 mounted on it.

[0068] Specifically, a transverse mounting crossbeam 11 for the imaging plate 31 is horizontally arranged at the top of the frame 1. The imaging plate 31 mounting crossbeam 11 is made of high-strength alloy material to ensure that it can withstand the weight of the imaging plate assembly 3. The imaging plate 31 mounting crossbeam 11 extends laterally, with its extended end protruding from the main body of the frame 1, providing sufficient space for installing and operating the imaging plate 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 33, and an imaging plate lifting drive motor 34.

[0070] Specifically, the lifting drive belt 32 is made of high-strength, wear-resistant synthetic material, possessing good flexibility and load-bearing capacity. One end of the lifting drive belt 32 is securely fitted onto the drive belt reel 33, while the other end is fixedly connected to the top of the imaging plate 31, enabling the vertical lifting and lowering movement of the imaging plate 31. The drive belt reel 33 is installed on one side of the mounting crossbeam 11 of the imaging plate 31 and is directly connected to the output end of the imaging plate lifting drive motor 34. The drive belt reel 33 rotates to wind up or release the lifting drive belt 32, thereby controlling the lifting height of the imaging plate 31.

[0071] Furthermore, the imaging plate lifting drive motor 34 is a high-performance, low-noise DC motor or servo motor, installed on the other side of the imaging plate 31 mounting crossarm 11. The imaging plate lifting drive motor 34 is connected to the drive belt take-up wheel 33, which can precisely control the rotation direction and speed of the drive belt take-up wheel 33, thereby realizing the smooth lifting of the imaging plate 31. This allows the imaging plate 31 to move to the metal fitting 71 to be inspected at different heights, realizing the imaging inspection process, meeting all-round inspection needs, and improving 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 mounted on the frame 1 and serves as one of the main power sources for the X-ray imaging assembly 2, driving the vertical lifting movement of the X-ray imaging camera 22 and its mounting frame 24. By controlling the forward and reverse rotation of the motor, the X-ray imaging camera 22 can achieve imaging at different heights to meet the inspection needs of cable 7 connection fittings 71 at different locations.

[0074] Furthermore, the X-ray imaging camera 22 is rotatably mounted on the fixed frame 24 for X-ray imaging of the cable 7 connecting hardware 71. It is equipped with a high-resolution X-ray detector that 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 operates, the X-ray hoisting drive belt 23 tightens or loosens accordingly, thereby driving the fixed frame 24 and the X-ray imaging camera 22 on it to move vertically. 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 mounted on the frame 1, the X-ray imaging camera 22 is rotatably mounted on the fixed frame 24, and 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.

[0077] Specifically, to increase the flexibility of the X-ray imaging camera 22, a rotary drive motor 25 and a drive rod 26 are added. The output end of the rotary drive motor 25 is connected to the drive rod 26, which in turn is connected to the X-ray imaging camera 22. When the rotary drive motor 25 is working, it drives the drive rod 26 and the X-ray imaging camera 22 to rotate together, thereby enabling the camera to rotate horizontally and adjust the overall angle. This allows the X-ray imaging camera 22 to capture images of the cable 7 connection fittings 71 over a wider area, improving the comprehensiveness and accuracy of the inspection.

[0078] Combination Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the guide component 6 provided in one embodiment of the present application. In some embodiments, the detection device further includes the guide component 6 disposed below the frame 1.

[0079] Specifically, the guiding component 6 is composed of a first guiding frame 61 and a second guiding frame 62, forming an N-shaped structure. This structural design helps to enhance the overall stability of the guiding component 6 and also enables the guiding component 6 to guide the testing equipment to land quickly and accurately on the power transmission cable 7, shortening the testing time and thus improving testing efficiency.

[0080] Furthermore, the first guide frame 61 includes a first segment 610 and a second segment 611. One end of the first segment 610 is connected to the bottom of the frame 1, and one end of the second segment 611 is also connected to the bottom of the frame 1. The connection between the second segment 611 and the first segment 610 forms a certain arc. This arc design allows the guide assembly 6 to accurately fall between the two cables 7, ensuring rapid installation of the testing equipment.

[0081] Furthermore, one end of the second guide frame 62 is set on the frame 1, forming part of the N-shaped structure together with the first guide frame 61. The other end of the second guide frame 62 is inclined towards the outside of the frame 1. This inclined design makes it easier for the detection equipment to be moved or adjusted when needed, with the help of the guidance of the second guide frame 62.

[0082] Combination Figure 8 As shown, Figure 8This is a schematic diagram of the structure of a drone 8 detection system provided in one embodiment of this application. In some embodiments, a drone 8 detection system is also provided, including a detection device for the power transmission cable 7 connecting hardware 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 attachment ring 12 disposed on the top of the frame 1.

[0084] In one embodiment, the drone 8 detection system includes: drone 8 and drone attachment / removal assembly 81 for connection to drone attachment / removal assembly 81.

[0085] In one embodiment, the drone attachment / removal assembly 81 includes an attachment / removal ring 810, a hook 811, and a wind vane 812.

[0086] Specifically, the hook-and-unhook ring 810 is connected to the drone 8 via a movable locking buckle 813. Its material is a flexible traction rope, which has good flexibility and durability. The flexible traction rope can move up and down to achieve a self-balancing effect, allowing the hook-and-unhook ring 810 to easily adapt to various complex environments while ensuring a safe and reliable connection.

[0087] Furthermore, hook 811 is mounted on hook-and-unhook ring 810 for connection to drone hook ring 12 at the top of frame 1. When drone 8 hovers in the designated position, the operator can remotely control hook 811 to quickly and accurately engage with drone hook ring 12, thereby stably suspending the testing equipment below drone 8.

[0088] Furthermore, the wind-stabilizing wing plate 812 is mounted on the attachment ring 810, and the wind-stabilizing wing plate 812 has air guide holes 814 to reduce wind resistance and airflow interference, ensuring that the wind-stabilizing wing plate 812 always maintains a good attitude. This helps to suppress the swaying and shaking of the UAV attachment assembly 81 during high-altitude operations, improving the stability and safety of the UAV 8 during flight. At the same time, the wind-stabilizing wing plate 812 also helps to protect the hook 811 and attachment ring 810 to a certain extent, preventing them from being damaged by excessive wind.

[0089] As described above, by using drone 8 to carry inspection equipment, it is possible to quickly reach the vicinity of power lines for inspection, improving inspection efficiency. X-ray imaging technology can clearly capture the internal structure of the connecting hardware 71 of the power transmission cable 7, ensuring the accuracy of the inspection results. Drone 8 inspection avoids the safety risks associated with manual inspection. The drone attachment / dismounting component 81 makes the connection and disconnection between the inspection equipment and drone 8 very simple and quick, improving the system's flexibility and adaptability.

[0090] In the specific implementation process, firstly, the operator selects the number of strands of the cable to be inspected (e.g., 6 or 8 strands) via the control panel. The control panel automatically pops up the corresponding inspection operation page, displaying the location of the cable 7 to be inspected. Secondly, the operator clicks the inspection button on the operation page. The control panel sends a signal to the drive component 4, driving the inspection equipment to move, while simultaneously controlling the imaging plate component 3 and the X-ray imaging component 2 to rise and fall to the first inspection position. Then, the X-ray imaging component 2 begins to work, performing X-ray inspection on the connecting hardware 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 inspection of one cable 7 location, the operator clicks the next inspection button, controlling the imaging plate component 3 and the X-ray imaging component 2 to descend to the second inspection position, repeating the above inspection steps. After completing the inspection of one side of the connecting hardware 71, the drone 8 is used to lift the entire inspection equipment and rotate it 180°, then reinstall it above the other side of the power transmission cable 7 to be inspected, performing the inspection of the other side of the connecting hardware 71, repeating the above inspection steps.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
