Description

Technical Field

[0001] This utility model relates to the field of testing technology for hardware of split transmission lines, specifically an X-ray testing device for spacers of split transmission lines. Background Technology

[0002] Split transmission lines are widely used due to their ability to effectively reduce corona discharge and energy loss. Spacer bars, as a key component, are used to fix the spacing between the split transmission lines, prevent them from colliding with each other, and suppress vibration. However, the bolts, connectors, or welds inside the spacer bars are prone to micro-cracks or metal fatigue under long-term vibration loads.

[0003] X-ray inspection has become an important non-destructive testing method due to its unique ability to identify internal defects in parts. For example... Figure 9 As shown, due to the limited gaps between adjacent transmission conductors in a split transmission conductor bundle, and the fact that the spacer bars of the split transmission conductors connect multiple conductors, are located inside the conductor bundle, and have a large volume, it is difficult to place the imaging plate for X-ray detection within the split transmission conductor bundle to detect the entire spacer bar. This makes it impossible to apply X-ray detection methods to the detection of spacer bars in split transmission conductors. Utility Model Content

[0004] The present invention aims to provide an X-ray inspection device for spacers of split transmission lines, so as to achieve rapid inspection of spacers of split transmission lines.

[0005] To solve the above technical problems, the specific solution adopted by this utility model is as follows: It includes a suspension plate with a hook at the top for connecting a drone. An X-ray machine is mounted on one side of the suspension plate via a connecting frame. A connecting plate is provided on the other side of the suspension plate. A first imaging plate and a second imaging plate are respectively hinged to the connecting plate via a first hinge shaft and a second hinge shaft. The first and second imaging plates rotate under the drive of the first and second hinge shafts to interlock and form a complete imaging plate in the direction in which the X-ray machine emits X-rays. A first gear and a second gear meshing with each other are fixedly connected to the first and second hinge shafts respectively. A drive motor is fixedly mounted on the connecting plate, and the output shaft of the drive motor is connected to the first hinge shaft. The drive motor drives the first hinge shaft to rotate, causing the meshing first gear and second gear to rotate synchronously, thereby controlling the first and second imaging plates to complete the splicing or resetting action.

[0006] Further optimization of an X-ray inspection device for a split transmission line spacer: The suspension plate and the connecting plate are provided with a connected wiring groove. A start switch is embedded in the wiring groove located directly below the hook. The start switch is connected to the drive motor through the connecting wire laid in the wiring groove. A through hole is opened at the hook connection position on the suspension plate. The bottom end of the hook extends through the through hole into the wiring groove and is connected to a counterweight block located above the start switch. When the hook is pulled or released by an external force, the counterweight block moves together with the hook to release or trigger the start switch.

[0007] Further optimization of an X-ray inspection device for a split transmission line spacer: a buffer pad is provided between the counterweight and the start switch.

[0008] Further optimization of an X-ray inspection device for a split transmission line spacer: a wire clamping groove is provided below the suspension plate, which is used to clamp the inspection device onto the split transmission line.

[0009] Further optimization of the X-ray inspection device for a split transmission conductor spacer: the inner wall of the cable slot is provided with an insulating anti-slip pad.

[0010] Further optimization of an X-ray detection device for a split transmission line spacer: the complete imaging plate formed by splicing the first imaging plate and the second imaging plate is quadrilateral or hexagonal.

[0011] Further optimization of an X-ray inspection device for a split transmission line spacer: a strip groove is provided inside the suspension plate along the X-ray emission direction, and a slide rail is provided in the strip groove. The connecting frame can be slidably mounted on the slide rail to adjust the distance between the X-ray machine and the spacer.

[0012] Further optimization of an X-ray inspection device for a split transmission line spacer: a safety frame is provided at the edge of the imaging plate.

[0013] Beneficial effects: This invention, through its foldable imaging plate design, allows the X-ray machine and imaging plate to easily pass through the gaps in the split power transmission lines and be placed on both sides of the spacer bar. The structure, with a suspension plate mounted on the split power transmission line, enables automatic detection, effectively solving the problem of difficult detection of spacers within split power transmission line bundles. This device is suitable for live-line work, avoiding economic losses caused by power outage detection.

[0014] This invention employs a synergistic design of hooks, through holes, counterweights, and a start switch: when the drone is connected to the hook suspension device, the imaging plate is in a folded (unspliced) state, ensuring that the imaging plate and X-ray machine can smoothly enter the split power transmission line bundle; when the device is placed on the split power transmission line, the first and second imaging plates automatically splice together to form a complete imaging plate, enabling rapid detection.

[0015] This invention designs the imaging plates to be assembled into a quadrilateral or hexagonal shape to meet the detection requirements of two-split, four-split, and six-split transmission lines, thus having a wide range of applications. Attached Figure Description

[0026] Example 1

[0027] like Figure 1As shown, an X-ray inspection device for split transmission line spacers includes a suspension plate 1, which serves as the structural framework of the entire device and the mounting carrier for each component.

[0028] The top of the suspension plate 1 is equipped with a hook 3, which is used to connect to the drone 25.

[0029] like Figure 5 and Figure 7 As shown, a strip groove 23 is formed on the suspension plate 1 along the X-ray emission direction, and a slide rail 24 is provided in the strip groove 23. The connecting frame 4 is slidably mounted on the slide rail 24, and the X-ray machine 5 is mounted on the connecting frame 4. The sliding design of the connecting frame 4 is used to adjust the distance between the X-ray machine 5 and the spacer 28 to obtain a good imaging effect.

[0030] like Figure 2 and Figure 4 As shown, a connecting plate 12 is provided on the side of the suspension plate 1 away from the connecting frame 4. The first imaging plate 7 and the second imaging plate 8 are hinged to the connecting plate 12 by the first hinge shaft 17 and the second hinge shaft 15, respectively. The first imaging plate 7 and the second imaging plate 8 rotate under the drive of the first hinge shaft 17 and the second hinge shaft 15, respectively, so as to splice them together to form a complete imaging plate 16 located in the X-ray emission direction of the X-ray machine 5. Since the main body of the spacer 28 is located in the split transmission conductor bundle, and the gap between the adjacent transmission conductors 27 of the split transmission conductor bundle is limited, it is difficult to place the complete imaging plate 16 in the split transmission conductor bundle. Therefore, the imaging plate 16 enters the split transmission conductor bundle in the folded state of the first imaging plate 7 and the second imaging plate 8, and then the imaging plate 16 is spliced ​​under the drive of the first hinge shaft 17 and the second hinge shaft 15.

[0031] like Figure 3 As shown, a first gear 9 and a second gear 10, which mesh with each other, are fixedly connected to the first hinge shaft 17 and the second hinge shaft 15, respectively. A drive motor 11 is fixedly mounted on the connecting plate 12. The output shaft 13 of the drive motor 11 is connected to the first hinge shaft 17. The drive motor 11 drives the first hinge shaft 17 to rotate, causing the meshing first gear 9 and second gear 10 to rotate synchronously, thereby controlling the first imaging plate 7 and the second imaging plate 8 to complete the splicing or resetting operation. The drive motor 11's control of the imaging plate 16 for splicing and resetting improves the automation level and working efficiency of the detection device.

[0032] like Figure 6 As shown, the suspension plate 1 and the connecting plate 12 are provided with a communicating wiring groove 21. A start switch 20 is embedded in the wiring groove 21 located directly below the hook 3. The start switch 20 is connected to the drive motor 11 through a connecting wire 22 laid in the wiring groove 21. The operation signal generated by the start switch 20 is transmitted to the drive motor 11 through the connecting wire 22, thereby causing the drive motor 11 to operate and control the imaging plate 16 to perform splicing or resetting actions.

[0033] A through hole 26 is provided at the connection position of the hook 3 on the suspension plate 1. The bottom end of the hook 3 extends through the through hole 26 into the wiring groove 21 and connects with the counterweight 18 located above the start switch 20. When the drone 25 is connected to the hook 3 to suspend the device, the hook 3 is pulled by an external force and drives the counterweight 18 to suspend in the air. At this time, the start switch 20 is in the untriggered state, and the imaging plate 16 is in the folded (unassembled) state. When the drone 25 disconnects from the hook 3 and places the device on the split power transmission line 27, the hook 3 is not pulled by an external force, and the counterweight 18 falls and contacts the start switch 20. At this time, the start switch 20 is in the triggered state, and the imaging plate 16 is in the unfolded (assembled) state. When the detection is completed, the drone 25 pulls the hook 3 again, the counterweight 18 is suspended in the air again, the start switch 20 is released, and the imaging plate 16 is folded back to its original position.

[0034] A buffer pad 19 is provided between the counterweight 18 and the start switch 20. The buffer pad 19 prevents the start switch 20 from being damaged by the impact when the counterweight 18 falls.

[0035] A wire clamping groove 2 is provided below the suspension plate 1. The wire clamping groove 2 is used to clamp the detection device on the split transmission line 27. The inner wall of the wire clamping groove 2 is provided with an insulating anti-slip pad 6. Through the physical groove structure and the insulating anti-slip pad 6, the detection device can be quickly, stably and safely positioned on the split transmission line 27, which improves the stability of the detection process.

[0036] An image plate 16 is provided with a safety frame 14 at its edge. The safety frame 14 provides a rigid protective barrier for the edge of the image plate 16, which significantly reduces the risk of damage caused by collision when the device is operating in a complex environment.

[0037] In this embodiment, the complete imaging plate 16 formed by splicing the first imaging plate 7 and the second imaging plate 8 is hexagonal. The hexagon can be adapted to the six-split transmission conductor bundle, so as to realize the spacer bar 28 of the six-split transmission conductor 27 without blind spots.

[0038] The method of using the X-ray inspection device for the spacer bar of the split transmission line of this utility model is as follows: Before operation, the position of the connecting frame 4 is preset according to the parameters of the six-split transmission line 27; then, the drone 25 suspends the connecting frame 4, connecting plate 12 and auxiliary components (X-ray machine 5, imaging plate 16) of the inspection device in the transmission line bundle on both sides of the target spacer bar 28 through the hook 3; next, the drone 25 is controlled to descend, and the wire clamping groove 2 of the suspension plate 1 is clamped on the transmission line 27; at this time, the drone 25 and the hook 3 are disconnected, and the counterweight 18 is triggered to start the operation. Switch 20 is turned off, which causes the drive motor 11 to rotate and splice the first imaging plate 7 and the second imaging plate 8 into a complete imaging plate 16. Then, the X-ray machine 5 emits X-rays that penetrate the spacer bar 28 and project onto the imaging plate 16. At the same time, the imaging plate 16 receives the X-ray signal to detect the spacer bar 28 of the six-split power transmission line 27. After the detection is completed, the UAV 25 reconnects the hook 3, pulls the counterweight block 18 to release the start switch 20, and causes the drive motor 11 to reset the first imaging plate 7 and the second imaging plate 8. The UAV 25 then returns to the ground with the equipment.

[0039] Example 2

[0040] This embodiment is an optimization based on Embodiment 1.

[0041] like Figure 8 As shown, the complete imaging plate 16 formed by splicing the first imaging plate 7 and the second imaging plate 8 is quadrilateral. The quadrilateral shape can be adapted to two-split and four-split transmission conductor bundles, realizing blind-angle detection of the spacer bars 28 of two-split and four-split transmission conductors 27. The various forms of imaging plates 16 can meet the detection requirements of spacer bars 28 of different types of split transmission conductors 27, improving the practicality of the device.
