Description

Technical Field

[0001] This invention relates to the field of X-ray power testing technology, and more specifically, to an X-ray testing device and method for multi-splitter power transmission fittings. Background Technology

[0002] Tension clamps are key transmission hardware used on tension towers (or angle towers) of multi-split transmission lines. Their core function is to reliably anchor multiple split sub-conductors to the insulator string (or tower body), bear the full tension (pull) of the conductors, and transfer the tension to the tower foundation, while ensuring good electrical connection and necessary mechanical flexibility.

[0003] Unlike single-conductor systems, multi-branched conductors consist of multiple (typically 4, 6, 8, or more) sub-conductors bundled together. This necessitates special designs for tension clamps to handle the simultaneous anchoring and tension balance of multiple sub-conductors. Therefore, the health status of tension clamps during service becomes a crucial maintenance parameter in power equipment overhaul. Currently, tension clamp defect detection primarily targets systems in service, resulting in high voltage. This environment significantly limits detection methods. Furthermore, tension clamp defects are often internal defects caused by crimping and fatigue. Therefore, in practice, X-ray inspection is commonly used for monitoring in high-altitude, high-voltage environments.

[0004] In the existing technology, although there are many detection devices and methods, due to the limitations of the application scenarios, for multi-segment detection scenarios, the detection devices may require the drone to change direction in actual detection, the jumpers of power transmission lines may not be detected, and there may be problems such as image occlusion between conductors. Summary of the Invention

[0005] The purpose of this invention is to provide an X-ray inspection device and method for multi-splitter power transmission fittings, which addresses the shortcomings of existing technologies by providing a solution and features good imaging effect, high inspection efficiency, and good inspection adaptability.

[0006] The embodiments of the present invention are implemented as follows: In a first aspect, the present invention provides an X-ray inspection device for multi-split power transmission fittings, including a support frame and a drone mount disposed on the support frame. The width of the support frame is adjustable, and the support frame is provided with an X-ray machine adjustment component and a detector adjustment component. The X-ray machine adjustment assembly includes a telescopic structure, a support platform, and a horizontally positioned X-ray machine. The upper end of the telescopic structure is connected to the load-bearing frame, and the lower end of the telescopic structure is connected to the support platform. The horizontally positioned X-ray machine is installed on the support platform. The detector adjustment assembly includes a six-axis manipulator, a rotary joint, and a detector. The upper end of the six-axis manipulator is connected to the support frame, and the lower end of the six-axis manipulator is equipped with a rotary joint, which is connected to the detector.

[0007] In some embodiments of the present invention, a telescopic joint is also included, which is disposed between the support frame and the six-axis robot.

[0008] In some embodiments of the present invention, the top of the six-axis manipulator is rotatably connected to the bottom of the telescopic joint.

[0009] In some embodiments of the present invention, a connecting block is also included, one side of which is fixedly connected to the rotating joint and the other side is connected to the detector.

[0010] In some embodiments of the present invention, the telescopic structure includes a telescopic motor and a telescopic component, wherein a lifting rope is connected to the telescopic motor and the lifting rope is wound around the telescopic component.

[0011] In some embodiments of the present invention, the telescopic assembly includes at least three telescopic frames connected by lifting ropes, namely a first telescopic frame, a second telescopic frame and a third telescopic frame. The first telescopic frame is fixedly connected to the upper layer of the supporting frame, the second telescopic frame is sleeved on the first telescopic frame, the third telescopic frame is sleeved on the second telescopic frame, and the bottom of the third telescopic frame is connected to a support platform.

[0012] In some embodiments of the present invention, guide components are provided at both the upper and lower ends of the telescopic mesh frame. The guide components include two support blocks, and a guide wheel is provided between the two support blocks. The lifting ropes are connected to the three telescopic mesh frames by wrapping around the guide wheel.

[0013] In some embodiments of the present invention, a front frame and a rear frame are fixedly installed on the support platform. The front frame and the rear frame are provided with mounting holes. The horizontal X-ray machine is provided with a protective shell. The front end and the rear end of the protective shell are connected to the support platform through mounting holes. A rotary motor is also fixedly installed on the front frame. The rotary motor is connected to the front end of the protective shell through the front mounting hole.

[0014] In some embodiments of the present invention, a walking mechanism and a control unit are also included. The walking mechanism is disposed on the lower layer of the support frame, and the control unit is disposed on the upper layer of the support frame. The walking mechanism includes four walking wheels symmetrically disposed on the lower layer of the support frame, and the walking wheels are provided with hydraulic telescopic rods and locking components.

[0015] Secondly, the present invention also provides an X-ray inspection method for multi-splitter power transmission fittings, including the above-mentioned inspection device, and the steps are as follows: S1. After the preliminary preparations are completed and the detection points of the power transmission line are confirmed, the drone will hoist the detection device onto the power transmission line. S2, by controlling the detection device, reach the designated detection point, adjust the position, and confirm the initial optimal detection point; S3, inspect the top two power transmission fittings. The telescopic structure in the X-ray machine adjustment assembly is not adjusted. At this time, the length of the telescopic structure is the first length. The angle of the X-ray machine is deflected to the first angle. At this time, the detector assembly uses the adjustment of the six-axis manipulator and the rotary joint to bypass the line and jumper wire and place the detector above the top two power transmission fittings to realize the inspection of the top two power transmission fittings. S4, inspect the two middle power transmission fittings. The telescopic structure in the X-ray machine adjustment assembly extends to the second length, and the angle of the X-ray machine deflects to the second angle. At this time, the detector assembly uses the adjustment of the six-axis manipulator and the rotary joint to bypass the line and jumper, and place the detector above the two middle power transmission fittings to achieve the inspection of the two middle power transmission fittings. S5, inspect the bottom two power transmission fittings. The telescopic structure in the X-ray machine adjustment assembly extends to the third length, and the X-ray machine angle deflects left and right to the third angle. At this time, the detector assembly uses the adjustment of the six-axis manipulator and the rotary joint to bypass the lines and jumpers and place the detector above the bottom two power transmission fittings to achieve the inspection of the bottom two power transmission fittings. S6. After the inspection is completed, the X-ray machine adjustment component and the detector adjustment component are both adjusted back to their initial state. The UAV hoisting inspection device returns to the ground, and the detected image data is transmitted to the control terminal for processing and identification.

[0016] The embodiments of the present invention have at least the following advantages or beneficial effects: Effect 1: Excellent imaging effect; This invention uses the telescopic adjustment of the X-ray machine to reach different irradiation positions, and uses the detector adjustment component to bypass power transmission lines, power transmission fittings and jumpers. Each shot is an image of a single power transmission fitting, so there is no ghosting or obstruction problem of multiple power transmission lines, nor is there any defect of blurry or incomplete imaging due to distance and focal length issues, thus having the characteristic of excellent imaging quality.

[0017] Secondly, the detection efficiency is high. This invention also utilizes a horizontally positioned X-ray machine and its telescopic adjustment to reach different irradiation positions. The detector adjustment component bypasses power lines, power fittings, and jumpers to reach the power fitting to be inspected, with each image focusing on a single power fitting. Furthermore, each time the X-ray machine stops, it rotates left and right twice, coordinating with the detector's positioning, enabling the inspection of two power fittings simultaneously. The next stop allows for the simultaneous inspection of both fittings at once, avoiding the problems of existing technologies that cannot inspect two fittings at once and require repositioning, as well as the need for drone-borne remounting to cross jumpers, significantly improving detection efficiency.

[0018] Thirdly, the invention offers excellent adaptability to various testing conditions. Firstly, by utilizing the adjustable width of the supporting frame, the horizontal X-ray machine, the telescopic structure, and the detector adjustment components, it can perform X-ray inspections on 2, 4, 6, and 8-splitter power transmission fittings. Secondly, the invention can perform inspections on various situations involving the same line, such as horizontal and vertical jumpers, and high-voltage iron heads. It can also inspect tension clamps, thus demonstrating excellent adaptability to different testing conditions. Attached Figure Description

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention 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 the present invention.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances. Example

[0028] Please refer to Figures 1-4 , specifically Figures 1-4 The figure shown is one embodiment of the present invention.

[0029] It should be noted beforehand that this invention is applicable to X-ray inspection of transmission fittings on transmission lines with multiple splits such as 2, 4, 6, and 8. This invention uses a 4-split configuration as the drawing and description, and the other split configurations can be adapted and implemented in the same way.

[0030] Firstly, this invention provides an X-ray inspection device for multi-splitter power transmission fittings, comprising a support frame 1 and a drone mount 2 mounted on the support frame 1. The width of the support frame 1 is adjustable, and the support frame 1 is equipped with an X-ray machine adjustment assembly and a detector 14 adjustment assembly. The adjustable width of the support frame 1 is designed to accommodate the spacing between the uppermost two transmission lines of different split power transmission conductors, allowing the invention to accurately land on it for movement and X-ray inspection, thereby improving the applicability of the invention. Many specific adjustable structures are possible, and no particular limitation is made here; this invention uses a multi-section telescopic rod structure.

[0031] The X-ray machine adjustment assembly includes a telescopic structure 3, a support platform 5, and a horizontally positioned X-ray machine 4. The upper end of the telescopic structure 3 is connected to the support frame 1, and the lower end of the telescopic structure 3 is connected to the support platform 5. The horizontally positioned X-ray machine 4 is mounted on the support platform 5. In current X-ray electrical testing technologies, vertically positioned pulsed X-ray machines are almost always used, with the emission port located at the top of the machine. This makes it impossible for this type of X-ray machine to deflect vertically due to its own length and the obstruction caused by the adjacent power lines. In contrast, this invention uses a horizontally positioned cold cathode X-ray machine with the emission port on the side. To achieve deflection, only the machine itself needs to rotate, without requiring overall left-right movement, making it suitable for multi-splitting detection scenarios.

[0032] Specifically, the telescopic structure 3 in this embodiment includes a telescopic motor (not specifically shown in the attached drawings) and a telescopic assembly 7. A lifting rope 6 is connected to the telescopic motor and is wound around the telescopic assembly 7. The telescopic assembly 7 includes at least three telescopic frames connected by the lifting rope 6, namely a first telescopic frame 8, a second telescopic frame 9, and a third telescopic frame 10. This embodiment uses three, but other embodiments may use other numbers, and the principle is the same. The first telescopic frame 8 is fixedly connected to the upper layer of the supporting frame 1, the second telescopic frame 9 is sleeved on the first telescopic frame 8, and the third telescopic frame 10 is sleeved on the second telescopic frame 9. The bottom of the third telescopic frame 10 is connected to the support platform 5. The first telescopic frame 8 is fixed, while the second telescopic frame 9 and the third telescopic frame 10 can extend and retract. Guide assemblies 11 are provided at the upper and lower ends of the telescopic frames. The guide assembly 11 includes two support blocks, and a guide wheel is provided between the two support blocks. The lifting rope 6 connects the three telescopic frames by winding around the guide wheel. This arrangement can realize the extension and retraction of the three telescopic frames under gravity, and the cost is low. It does not use the hydraulic electric telescopic rod commonly used, thus saving on usage costs.

[0033] In practical use, the telescopic motor is connected to both ends of the lifting rope 6, and the lifting rope 6 is sequentially wrapped around the upper and lower ends of the three telescopic frames. With this setup, combined with the use of gravity, the three telescopic frames can be linked and extended, with very linear extension and contraction, and relatively stable and controllable extension and contraction.

[0034] The detector 14 adjustment assembly of the present invention includes a six-axis manipulator 12, a rotary joint 13, and a detector 14. The upper end of the six-axis manipulator 12 is connected to the support frame 1, and the lower end of the six-axis manipulator 12 is provided with the rotary joint 13, which is connected to the detector 14. The rotary joint 13 can rotate the detector 14 itself, thereby allowing it to easily bypass the line when crossing it, and thus reach the top of the line fitting to be inspected.

[0035] In this embodiment of the invention, a telescopic joint 15 is also included, which is disposed between the support frame 1 and the six-axis robot 12. The telescopic joint 15 increases the operating range of the six-axis robot 12, thereby enabling the detector 14 to cover a wider area and solving the problem of the long distance between the upper and lower ends of multi-split transmission lines.

[0036] It should be emphasized that, in the specific embodiment of the present invention, the top of the six-axis manipulator 12 is rotatably connected to the bottom of the telescopic joint 15. This rotatable connection allows the six-axis manipulator 12 to rotate 360°, thereby enabling the operating surface to be within the surrounding area, and thus allowing the connected detector 14 to cover multiple power transmission lines.

[0037] In a specific application, the invention also includes a connecting block 16, one side of which is fixedly connected to the rotating joint 13, and the other side is connected to the detector 14. This arrangement facilitates the connection of the detector 14 and makes subsequent replacement, disassembly, and maintenance easier.

[0038] To better facilitate the rotation of the horizontal X-ray machine 4, in this embodiment, a front frame and a rear frame are fixedly mounted on the support platform 5. The front and rear frames have mounting holes. The horizontal X-ray machine 4 is equipped with a protective shell, the front and rear ends of which are connected to the support platform 5 through the mounting holes. A rotary motor 19 is also fixedly mounted on the front frame, and the rotary motor 19 is connected to the front end of the protective shell through the front mounting hole. The protective shell, through the two frames, has a gap with the support platform 5, thus ensuring that it is not affected during the rotation of the X-ray machine.

[0039] In some embodiments of the present invention, a walking mechanism 17 and a control unit 18 are also included. The walking mechanism 17 is disposed on the lower layer of the supporting frame 1, and the control unit 18 is disposed on the upper layer of the supporting frame 1. The walking mechanism 17 includes four walking wheels symmetrically disposed on the lower layer of the supporting frame 1. The walking wheels are equipped with hydraulic telescopic rods and locking components. The control unit 18 is the control center of the device, controlling the start and stop of the walking mechanism 17, the detector 14 adjustment assembly, the X-ray machine adjustment assembly, etc., and establishing a communication connection with the control terminal on the ground. The walking mechanism 17, as the lower layer of the supporting frame 1, enables the overall detection device to contact the power transmission line; the hydraulic telescopic rod is provided to give the walking wheels a certain range of deformation capability and impact resistance capability, thereby protecting the overall detection device. The locking component (not specifically shown in the accompanying drawings) is a locking structure designed to prevent the overall detection device from slipping and shifting after reaching the designated position. There are many such structures, and no limitation is made here, as long as they can achieve the effect of preventing slippage.

[0040] Secondly, the present invention also provides an X-ray inspection method for multi-splitter power transmission fittings, which utilizes and implements the above-mentioned inspection device, and the steps are as follows: S1. After completing the preliminary preparations, confirm the detection points of the power transmission line, and use the drone to hoist the detection device onto the power transmission line; confirm how many branches the power transmission line has at the detection point, the spacing between the branches, conduct an overall inspection of the detection device, and ensure that the drone is properly secured, etc.

[0041] S2, by controlling the detection device, reach the designated detection point, adjust the position, and confirm the initial optimal detection point; S3, detect the top two power transmission fittings. The telescopic structure 3 in the X-ray machine adjustment assembly is not adjusted. At this time, the length of the telescopic structure 3 is the first length, and the angle of the X-ray machine is deflected to the first angle. At this time, the detector 14 assembly uses the adjustment of the six-axis manipulator 12 and the rotary joint 13 to bypass the line and jumper wire and place the detector 14 above the top two power transmission fittings to realize the detection of the top two power transmission fittings. S4, detect the two middle power transmission fittings. The telescopic structure 3 in the X-ray machine adjustment assembly extends to the second length, and the angle of the X-ray machine deflects to the second angle. At this time, the detector 14 assembly uses the adjustment of the six-axis manipulator 12 and the rotary joint 13 to bypass the line and jumper wire and place the detector 14 above the two middle power transmission fittings to realize the detection of the two middle power transmission fittings. S5, detect the bottom two power transmission fittings. The telescopic structure 3 in the X-ray machine adjustment assembly extends to the third length, and the angle of the X-ray machine deflects to the third angle. At this time, the detector 14 assembly uses the adjustment of the six-axis manipulator 12 and the rotary joint 13 to bypass the line and jumper wire and place the detector 14 above the bottom two power transmission fittings to realize the detection of the bottom two power transmission fittings. S6. After the inspection is completed, the X-ray machine adjustment component and the detector 14 adjustment component are both adjusted back to their initial state. The UAV hoisting inspection device returns to the ground, and the detected image data is transmitted to the control terminal for processing and identification.

[0042] It should be noted that S4 and S5 are adjusted according to the actual situation. In this embodiment, it is a four-part split, so we can stop at step S4 and go directly to step S6.

[0043] If it is a double-split transmission line, then S4-S5 are omitted directly; S3 goes directly to S6; If it is a six-split transmission line, then the complete S1-S6 steps are followed. If it is an eight-split transmission line, then it is the middle line of S4, which has two layers. Therefore, it needs to be repeated once. And this time, the angle and telescopic distance of the X-ray machine, as well as the position of detector 14, need to be adjusted again.

[0044] In summary, this invention, through the telescopic adjustment of the X-ray machine, reaches different irradiation positions. The detector 14 adjustment component bypasses power transmission lines, fittings, and jumpers, ensuring that each image is taken specifically for a single power transmission fitting. Therefore, there are no issues of ghosting or obstruction from multiple power transmission lines, nor are there defects such as blurred or incomplete images due to distance or focal length issues, resulting in excellent image quality. Similarly, this invention uses a horizontally positioned X-ray machine 4 and its telescopic adjustment to reach different irradiation positions. The detector 14 adjustment component bypasses power transmission lines, fittings, and jumpers, reaching above the power transmission fitting to be inspected, ensuring that each image is taken specifically for a single power transmission fitting. Furthermore, each time the X-ray machine stops, it rotates left and right twice, coordinating with the positioning of detector 14, enabling the detection of two power transmission fittings on the left and right. The next stop of the X-ray machine allows for the simultaneous detection of both fittings, avoiding the problems of existing technologies that cannot detect two fittings at once and require reversing direction, as well as the need for drone-assisted repositioning to cross positions when encountering jumpers. This significantly improves detection efficiency. In addition, this invention utilizes the adjustable width of the supporting frame 1, the horizontally positioned X-ray machine 4, the telescopic structure 3, and the adjustment components of detector 14 to achieve X-ray detection of power transmission fittings split into 2, 4, 6, and 8 sections. Secondly, this invention can perform detection for various situations on the same line, such as horizontal and vertical jumpers, and high-voltage iron heads, and can also detect tension clamps, thus exhibiting good adaptability.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
