Description

Technical Field

[0001] The present invention relates to the technical field of conductor fittings detection, and specifically to a split-type X-ray detection device for single and double split conductor fittings. Background Art

[0002] Split conductors are a commonly used type of conductor formation in high-voltage transmission lines. By arranging multiple sub-conductors in a bundle at a certain spacing, an equivalent large cross-section conductor is formed, thereby reducing energy loss and increasing transmission capacity. According to the number of sub-conductors, it can be divided into single split and double split, etc. Fittings are key components in the power system that connect conductors, insulators, and towers, and undertake important functions such as mechanical fixation, electrical insulation, and load transfer. With the expansion of the power grid scale and the increase in voltage levels, fittings are exposed to complex environments for a long time, resulting in defects such as cracks, wear, corrosion, or deterioration of the internal structure. Such defects not only weaken the structural strength, leading to mechanical failures such as conductor slippage and insulation breakdown, but may also induce electrical chain faults such as partial discharge and arc fusing, becoming major risk sources for power grid operation. Taking the strain clamp as an example, millimeter-level cracks inside it can cause wire breakage and tower collapse accidents due to stress concentration. Therefore, it is necessary to regularly detect fittings.

[0003] Traditional detection methods include visual inspection, infrared thermal imaging, and ultrasonic detection. These detection methods are limited by resolution and penetration depth, making it difficult to accurately identify hidden defects, and highly dependent on the operator's experience, with disadvantages such as low efficiency and high missed detection rate. Currently, non-destructive testing technologies such as digital radiography and X-ray imaging are developing rapidly. Among them, the flexible imaging plate adapts to complex scenarios such as high altitude and narrow spaces through lightweight design and bendable characteristics, and supports full-dimensional scanning of fittings by drones or handheld devices in the energized state.

[0004] Currently, the X-ray detection device is split-type, including an X-ray machine and an imaging plate assembly. When detecting fittings, the imaging plate assembly is hung on the conductor, and the drone carries the X-ray machine to irradiate the fittings, and the imaging plate receives the signal to detect the fittings; for double split conductor fittings, after detecting one fitting, it is necessary to lift the imaging plate assembly by the drone and flip it to hang on the other conductor, and then move the X-ray to the other side to irradiate the fittings to complete the detection. However, when detecting double split conductor fittings, it is necessary to flip the imaging plate assembly, that is, the operation process is relatively cumbersome and the detection efficiency is low. Summary of the Invention

[0005] In order to solve the problem that the operation process of the split-type detection device in the prior art is cumbersome and the detection efficiency is low, the present invention provides a split-type X-ray detection device for single and double split conductor fittings, which does not require flipping the imaging plate assembly when detecting two fittings, has a simple operation process, and improves the detection efficiency.

[0006] To achieve the above object, the specific solution adopted by the present invention is as follows: A split X-ray detection device for single and double split conductor fittings, comprising an X-ray machine and an imaging plate assembly that can be suspended on the conductor. The imaging plate assembly includes an imaging plate and two parallel hanging plates. The imaging plate is located on the same side of the two hanging plates. Both hanging plates are provided with inlet channels opening downward for the conductor to enter. The imaging plate assembly includes two first imaging plates and a second imaging plate arranged back to back. The first imaging plate is fixedly connected to the two hanging plates. The second imaging plate is connected to the first imaging plate through an airbag. By introducing gas into the airbag, the airbag can expand to push the second imaging plate to move away from the first imaging plate.

[0007] As an optimized solution of the above split X-ray detection device for single and double split conductor fittings: The two hanging plates are fixedly connected by a connecting rod perpendicular to them, and the connecting rod is located at the top of the hanging plates.

[0008] As another optimized solution of the above split X-ray detection device for single and double split conductor fittings: Each hanging plate is provided with a groove, and the edge of the first imaging plate is correspondingly clamped into the groove, and the top of the first imaging plate is fixedly connected to the connecting rod.

[0009] As another optimized solution of the above split X-ray detection device for single and double split conductor fittings: A limiting rod is slidably arranged on the hanging plate, and a spring for pushing one end of the limiting rod to enter from one side wall of the inlet channel is provided. The other end of the limiting rod is connected with a linkage wire, and pulling the linkage wire drives the end of the limiting rod to withdraw from the inlet channel.

[0010] As another optimized solution of the above split X-ray detection device for single and double split conductor fittings: An installation cylinder is arranged on the hanging plate, the limiting rod is slidably arranged in the installation cylinder, and the spring is located between the end of the limiting rod and the bottom of the installation cylinder.

[0011] As another optimized solution of the above split X-ray detection device for single and double split conductor fittings: A hook is arranged at the top end of the hanging plate. The hook includes a free end and a connecting end fixedly connected to the hanging plate.

[0012] As another optimized solution of the above split X-ray detection device for single and double split conductor fittings: One end of the linkage wire is connected to the limiting rod, the other end of the linkage wire passes through the installation cylinder, and after passing through a plurality of reversing wheels, it is connected to the free end of the hook, and the linkage wire blocks the opening of the hook.

[0013] As another optimization solution for the above-mentioned split-type X-ray detection equipment for single and double bundled conductor fittings: The number of reversing wheels is three, two of which are rotatably connected to the hanging plate, and the other reversing wheel is rotatably connected to the connecting end of the hook. The linkage wire passes through the two reversing wheels on the hanging plate and the reversing wheel at the connecting end in sequence and then is connected to the free end.

[0014] As another optimization solution for the above-mentioned split-type X-ray detection equipment for single and double bundled conductor fittings: A plurality of protective sleeves through which the linkage wire can pass are fixedly arranged on the hanging plate.

[0015] A method for detecting double bundled conductor fittings by using the above detection equipment includes the following steps:

[0016] S1, Hang the imaging plate assembly on the wire, with the first imaging plate and the second imaging plate located between two fittings.

[0017] S2, Inflate the airbag, and the inflated airbag pushes the second imaging plate to move away from the first imaging plate to the required position.

[0018] S3, Use the X-ray machine to irradiate one of the fittings for detection. After the detection is completed, adjust the position of the X-ray machine to irradiate the other fitting for detection.

[0019] S4, After both fittings are detected, remove the imaging plate assembly from the wire.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides a split-type X-ray detection equipment for single and double bundled conductor fittings. The first imaging plate and the second imaging plate are arranged back to back. Adjust the position of the X-ray machine to detect the double bundled conductor fittings. Specifically, when detecting the double bundled conductor fittings, hang the imaging plate assembly on one of the wires, use the X-ray machine to irradiate the wire fitting, and the first imaging plate receives the signal for detection; inflate the airbag, and the inflated airbag pushes the second imaging plate towards the other wire fitting, move the X-ray machine to irradiate the wire fitting, and the second imaging plate receives the signal for detection. That is, it is not necessary to flip the imaging plate assembly to detect the double bundled conductor fittings, the operation is simple, and the detection efficiency is improved; by inflating the airbag, the distance between the second imaging plate and its corresponding fitting is reduced, and the detection accuracy is improved.

[0022] 2. When hanging the imaging plate assembly, the wire is located at the bottom of the wire inlet channel. To prevent the imaging plate assembly from detaching from the wire, the length of the wire inlet channel is increased. Although this method has a certain effect of preventing wire detachment, when the imaging plate assembly shakes greatly, there is still a risk of wire detachment; and using this method increases the volume of the overall equipment. Therefore, in the present invention, a limiting rod is provided. When the wire enters and exits the wire inlet channel, the linkage wire is pulled to retract the limiting rod into the installation cylinder; after the wire enters the wire inlet channel, the force pulling the linkage wire is removed, and the spring pushes one end of the limiting rod to extend out of the installation cylinder and into the wire inlet channel, and the distance between the extended end of the limiting rod and the other side wall of the wire inlet channel is less than the diameter of the wire, restricting the wire at the bottom of the wire inlet channel and playing a role in preventing wire detachment.

[0023] 3. In the present invention, one end of the linkage wire is connected to the limiting rod, and the other end of the linkage wire is connected to the free end of the hook. When the imaging plate assembly is suspended by the drone, when the lifting rod of the drone enters the hook, it will pull the linkage wire, causing the limiting rod to retract into the installation cylinder, ensuring that the wire smoothly enters the wire inlet channel; after the imaging plate assembly is suspended on the wire, the lifting rod of the drone disengages from the hook, and the spring pushes one end of the limiting rod to extend out of the installation cylinder, without the need for an additional drive source to pull the linkage wire, making the operation more simple.

[0031] The technical solution of the present invention will be further elaborated in detail below in combination with specific embodiments. For the parts not detailedly recorded and disclosed in the following embodiments of the present invention, they should all be understood as the prior art known or should be known to those skilled in the art, such as how the airbag 7 is connected to the first imaging plate 2 and the second imaging plate 6, how the mounting cylinder 10 is mounted on the hanging plate 3, how the first imaging plate 2 and the second imaging plate 6 receive signals and detect, how to inflate and deflate the airbag 7, etc.

[0032] Embodiment 1

[0033] A split-type X-ray detection device for single and double split conductor fittings, as Figure 2 shown, includes an X-ray machine 1 and an imaging plate assembly that can be suspended on the wire. The imaging plate assembly includes an imaging plate and two parallel hanging plates 3. The imaging plate is located on the same side of the two hanging plates 3. Inlet channels 4 for the wire to enter are provided on the bottoms of the two hanging plates 3 and open downward. The bottom of the hanging plate 3 is bent toward the imaging plate side to form a bent portion 9, so that the inlet channel 4 is divided into a connected vertical channel and a bent channel, and the bent channel is located below the vertical channel. When the imaging plate assembly is suspended, the wire slides into from the opening of the bent channel and finally locates at the bottom of the vertical channel, so that the imaging plate assembly is suspended on the wire. The setting of the bent channel can play a certain role in preventing the wire from coming off.

[0034] The two hanging plates 3 are fixedly connected by a connecting rod 5 perpendicular to them, as Figure 6 shown, and the connecting rod 5 is located at the top of the hanging plate 3 and between the two hanging plates 3. The two ends of the connecting rod 5 are respectively fixedly connected to the corresponding hanging plates 3, and their connection method is bolt connection. In this embodiment, a plurality of holes are provided on the hanging plate 3, which plays a role in weight reduction.

[0035] As Figure 2 shown, the imaging plate assembly includes two first imaging plates 2 and second imaging plates 6 arranged back to back. The first imaging plates 2 and the second imaging plates 6 are both flexible imaging plates, and their specifications and dimensions are the same. The first imaging plates 2 and the second imaging plates 6 are located on the same side of the hanging plate 3. Among them, the first imaging plates 2 are located between the two hanging plates 3 and are fixedly connected to the two hanging plates 3. Specifically, the connection method is that a groove 8 is provided on each hanging plate 3. The groove 8 of the hanging plate 3 is opened on the side wall facing the other hanging plate 3 and extends from top to bottom; the two edges of the first imaging plate 2 are respectively clamped into the corresponding grooves 8, and the surface of the first imaging plate 2 is attached to the side wall of the groove 8, restricting the first imaging plate 2 between the two hanging plates 3; the top of the first imaging plate 2 is fixedly connected to the connecting rod 5, and their connection method is bolt connection. The two first imaging plates 2 and second imaging plates 6 arranged back to back do not require moving the imaging plate assembly to detect the double split conductor fittings, and the operation process is simple, improving the detection efficiency.

[0036] To ensure the detection accuracy of the second imaging plate 6, the second imaging plate 6 is connected to the first imaging plate 2 through an airbag 7, that is, one side of the airbag 7 is fixedly connected to the first imaging plate 2, and the other side of the airbag 7 is fixedly connected to the second imaging plate 6. By introducing gas into the airbag 7, the expansion of the airbag 7 can push the second imaging plate 6 to move away from the first imaging plate 2, reducing the distance between the second imaging plate 6 and its corresponding fitting, and improving the accuracy of fitting detection.

[0037] The process of detecting a single split conductor fitting is as follows: As Figure 2 shown, the imaging plate assembly is lifted above the wire by a drone and then lowered from top to bottom, allowing the wire to slide into the opening of the inlet channel 4 and finally located at the bottom of the inlet channel 4; the drone is separated from the imaging plate assembly, and another drone equipped with an X-ray machine 1 is located on the side of the fitting away from the first imaging plate 2. The X-ray machine 1 irradiates the fitting, and the signal is collected by the first imaging plate 2 to detect the fitting. After the detection is completed, the imaging plate assembly is lifted off the wire by the drone.

[0038] The process of detecting a double split conductor fitting is as follows: As Figure 3 shown, the imaging plate assembly is lifted above the wire by a drone and then lowered from top to bottom, allowing the wire to enter through the opening of the inlet channel 4 and finally located at the bottom of the inlet channel 4; then, gas is filled into the airbag 7, and the airbag 7 collides to push the second imaging plate 6 to move towards another fitting, reducing the distance between the two. The drone is separated from the imaging plate assembly; another drone equipped with an X-ray is located on the opposite side of the first imaging plate 2. The X-ray machine 1 irradiates the fitting, and the signal is collected by the first imaging plate 2 to detect the fitting; after the detection is completed, the drone moves the X-ray machine 1 to the opposite side of the second imaging plate 6, and the X-ray machine 1 is used to irradiate the fitting corresponding to the second imaging plate 6, and the signal is collected by the second imaging plate 6 to detect the fitting; after the detection is completed, the imaging plate assembly is directly lifted off, or the airbag 7 is deflated to reset the second imaging plate 6 and then the imaging plate assembly is lifted off.

[0039] The above is the basic implementation manner of the present invention, and further improvements, optimizations, and limitations can be made on this basis to obtain the following embodiments:

[0040] Embodiment 2

[0041] This embodiment is an improved solution based on Embodiment 1. Its main structure is the same as that of Embodiment 1. The improvement lies in that when the imaging plate assembly is suspended, the wire is located at the bottom of the wire inlet channel 4. To prevent the imaging plate assembly from detaching from the wire, the length of the wire inlet channel 4 is increased. Although this method has a certain effect of preventing wire detachment, when the imaging plate assembly shakes greatly, there is still a risk of wire detachment; and using this method increases the volume of the overall equipment. Therefore, in this embodiment, the imaging plate assembly is improved to prevent the imaging plate assembly from falling off the wire due to shaking, and the effect of preventing wire detachment is better.

[0042] At the top of both hanging plates 3, hooks 15 are provided. The hook 15 includes a free end and a connecting end fixedly connected to the hanging plate 3. As Figure 5 shown, the left part of the hook 15 is the connecting end and the right part is the free end. When the unmanned aerial vehicle hoists the imaging plate assembly, the hoisting rod 16 fixed on the unmanned aerial vehicle hooks the two hooks 15 to drive the imaging plate assembly to lift and lower.

[0043] As Figure 5 shown, a limiting rod 11 is slidably arranged on each hanging plate 3. The hanging plate 3 and the limiting rod 11 are arranged in such a way that a mounting cylinder 10 is fixedly connected to the side surface of the hanging plate 3. The mounting cylinder 10 is a cylindrical structure with one end open and one end closed, and the opening of the mounting cylinder 10 is inclined upward and towards the wire inlet channel 4. The limiting rod 11 is slidably arranged in the mounting cylinder 10. A spring 12 is arranged on the hanging plate 3 for pushing one end of the limiting rod 11 to enter from one side wall of the wire inlet channel 4. The spring 12 is located in the space between the end of the limiting rod 11 extending into the mounting cylinder 10 and the bottom of the mounting cylinder 10. The spring 12 can push one end of the limiting rod 11 to extend out of the mounting cylinder 10 and enter the wire inlet channel 4 from one side wall of the wire inlet channel 4, so that the distance between the protruding end of the limiting rod 11 and the other side wall of the wire inlet channel 4 is less than the diameter of the wire, restricting the wire at the bottom of the wire inlet channel 4 and preventing the imaging plate assembly from falling off the wire due to shaking, improving the stability of the imaging plate assembly.

[0044] In order to ensure that when the wire enters and exits the wire inlet channel 4, the limiting rod 11 retracts from the wire inlet channel 4 and retracts into the mounting cylinder 10, the other end of the limiting rod 11 is connected with a linkage wire 17. Pulling the linkage wire 17 drives the end of the limiting rod 11 to exit the wire inlet channel 4. Specifically, the end of the limiting rod 11 extending into the mounting cylinder 10 is connected with the linkage wire 17. One end of the linkage wire 17 is connected with the limiting rod 11, the other end of the linkage wire 17 passes through the mounting cylinder 10, and after passing through a plurality of reversing wheels 13, it is connected with the free end of the hook 15, and the linkage wire 17 blocks the opening of the hook 15. In this embodiment, the number of reversing wheels 13 is three, two of which are rotatably arranged on the surface of the hanging plate 3, and the remaining one reversing wheel 13 is rotatably arranged at the connecting end of the hook 15. The linkage wire 17 passes through the two reversing wheels 13 on the hanging plate 3 and the connecting end reversing wheel 13 in sequence and then is connected with the free end. As Figure 5As shown, the linkage wire 17 blocks the opening of the hanging hook 15.

[0045] When the imaging plate assembly is suspended on the wire, during the process that the lifting rod 16 of the UAV hooks the hanging hook 15, the linkage wire 17 is pulled to move into the hanging hook 15, and then the limiting rod 11 is pulled to withdraw from the wire inlet channel 4 and retract into the mounting cylinder 10. When the UAV lands, the wire enters the bottom of the wire inlet channel 4; when the UAV is separated from the imaging plate assembly, at this time, the lifting rod 16 is separated from the hanging hook 15, that is, the linkage wire 17 loses the upward pulling force. Under the action of the spring 12, the limiting rod 11 extends out of the mounting cylinder 10 and extends into the wire inlet channel 4 to limit the wire at the bottom of the wire inlet channel 4. The X-ray machine 1 detects the single-split wire fitting or the double-split wire fitting. After the detection is completed, the lifting rod 16 of the UAV hooks the hanging hook 15, pulls the linkage wire 17 to move into the hanging hook 15, and then pulls the limiting rod 11 to withdraw from the wire inlet channel 4. During the process that the UAV drives the imaging plate assembly to rise, the wire smoothly slides out of the wire inlet channel 4 to complete the whole detection. The coordinated action of the limiting rod 11 and the linkage wire 17 reduces manual intervention, further simplifies the operation process, improves the detection efficiency, and at the same time, avoids the risk of wire detachment at high altitude.

[0046] A plurality of protective sleeves 14 through which the linkage wire 17 can pass are fixedly arranged on the hanging plate 3. The protective sleeves 14 are arranged along the wiring path of the linkage wire 17. The linkage wire 17 is located between the protective sleeves 14 and the hanging plate 3, avoiding the exposure of the linkage wire 17 to the outside, not only playing a protective role for the linkage wire 17, but also avoiding the entanglement of the linkage wire 17 with other components.

[0047] Embodiment 3

[0048] A method for detecting a double-split wire fitting includes the following steps:

[0049] S1. Use a UAV to lift the imaging plate assembly above the wire, and then slowly lower it so that the wire slides into the wire inlet channel 4, and then suspend the imaging plate assembly on the wire. At this time, the first imaging plate 2 and the second imaging plate 6 are located between the two fittings.

[0050] S2. Inflate the airbag 7, and the inflated airbag 7 pushes the second imaging plate 6 to move away from the first imaging plate 2 to the required position, reducing the distance between the second imaging plate 6 and its corresponding fitting.

[0051] S3. Use the X-ray machine 1 to irradiate one of the fittings for detection. After the detection is completed, the UAV drives the X-ray machine 1 to adjust the position to irradiate the other fitting for detection;

[0052] S4. After both fittings are detected, the imaging plate assembly can be directly removed from the wire, or the imaging plate assembly can be removed from the wire after deflating the airbag 7.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
