Description

Technical Field

[0001] The present application relates to the maintenance of overhead lines, and in particular to a live detection device and live detection method for split conductors of power transmission lines. Background Art

[0002] Transmission lines are the core of power transmission, and their failures can easily cause widespread power outages. Multi-split conductors use a split-beam design to reduce electric field strength and improve transmission efficiency. However, crimped fittings are prone to internal defects (such as poor crimping and wire breakage) due to process issues, which are difficult to detect through conventional inspection.

[0003] X-ray detection technology, with its strong penetrating power, can non-destructively identify internal defects such as cracks and deformations in components such as tension clamps and connecting pipes without affecting line operation, and has become an important detection method.

[0004] However, existing X-ray inspection technology cannot inspect multiple wires in one task, resulting in low inspection efficiency. Therefore, a solution that can improve inspection efficiency is needed. Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides a live detection device and a live detection method for split conductors of a power transmission line.

When the annular airbag is in the first state, the flexible imaging plates are fitted one to one with the conductors to be tested. The drone carrier moves circumferentially along the cavity formed by the conductors to be tested. When the drone carrier is close to one of the conductors to be tested, the X-ray machine rotates relative to the drone carrier so that the rays emitted by the X-ray machine pass through the nearest conductor to be tested and reach the flexible imaging plate corresponding to the conductor to be tested.

[0009] In one embodiment, a walking wheel and a walking rod are provided below the walking mechanism; an annular groove is provided on the walking wheel, and one of the conductors to be tested is inserted into the annular groove; the walking rod is placed on the other conductor to be tested.

[0010] In one embodiment, a driving motor is provided in the traveling mechanism, and the driving motor is in transmission connection with the first traveling wheel or the second traveling wheel.

[0011] In one embodiment, a first traction ring is provided on the walking mechanism, a second traction ring is provided on the UAV carrier, and a traction rope is connected between the first traction ring and the second traction ring.

[0012] In one embodiment, the charge detection device further includes a rotation adjustment component, which is fixed to the UAV carrier, and the X-ray machine is rotationally connected to the rotation adjustment component.

[0013] In one embodiment, the rotation adjustment assembly includes a gantry, a rotating sleeve and a drive unit. The gantry is fixed on the UAV carrier and spans the through hole. The rotating sleeve is mounted on the crossbeam of the gantry. The X-ray machine is fixed on the rotating sleeve. The drive unit is connected to the rotating sleeve in a transmission manner.

[0014] In one embodiment, the charged detection device further includes an adjustable telescopic rod, the base and the traveling mechanism are fixedly connected to the adjustable telescopic rod respectively, and the adjustable telescopic rod is used to adjust the distance between the base and the traveling mechanism.

[0015] In one embodiment, the charged detection device further includes a plurality of counterweights, the weights of the plurality of counterweights are equal, and the plurality of counterweights are connected to the UAV carrier by snapping, magnetism, or bolts.

[0016] The second aspect of the present application provides a live detection method, which is applied to the live detection device provided in the first aspect of the present application. The live detection method includes: switching the annular airbag to a first state with air, so that a plurality of flexible imaging plates are fitted one-to-one with a plurality of conductors to be tested; controlling the UAV carrier and the walking mechanism to move forward synchronously; controlling the X-ray machine to rotate and emit rays, so that the rays pass through the conductor to be tested closest to the UAV carrier in turn and reach the flexible imaging plate corresponding to the conductor to be tested; receiving and processing images from a plurality of flexible imaging plates.

[0017] In one embodiment, before switching the annular airbag to the first state with air, the live detection method further includes: placing the walking mechanism on the conductor to be tested located above, and placing the annular airbag in the second state without air in the space formed by the conductors to be tested.

[0018] Compared with the prior art, the embodiment of the present application provides a device and method for detecting a split conductor of a power transmission line with a charge, and has the following advantages:

[0019] After the annular airbag in the imaging assembly is inflated, several flexible imaging plates can be simultaneously attached to several conductors under test. The drone vehicle moves circumferentially along the cavity formed by the conductors. When the drone vehicle approaches one of the conductors under test from the outside, the X-ray machine rotates relative to the drone vehicle, and the X-ray machine's radiation passes through the conductor under test and reaches the corresponding flexible imaging plate. By simply adjusting the drone vehicle's position and the X-ray machine's angle, multiple conductors under test can be inspected in a single mission while moving. Compared to the traditional method of inspecting only one conductor under test per mission, this greatly improves the efficiency of detecting split conductors on power transmission lines, saving considerable time and labor costs.

DETAILED DESCRIPTION

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] In the description of the present application, it should be understood that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are intended to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate so that the embodiments of the present application can be implemented in a marking manner other than that shown or described. In addition, "including", "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of components, steps or units is not necessarily limited to those components, steps or units that are explicitly listed, but may also include other components, steps or units that are not explicitly listed but are inherent to these processes, methods, products or devices. In the present application, the conductor to be tested can refer to the conductor itself, or to components such as tension clamps and connecting pipes on the conductor. The specific component referred to depends on the detection target of the actual task.

[0030] Overhead transmission lines are crucial for long-distance power transmission and are crucial to modern life and production. Failures in these lines can severely impact industrial production and public life, causing widespread power outages and significant economic losses. As electricity demand grows, multi-split conductor technology is being widely adopted to improve transmission line capacity. This technology splits a single conductor into multiple smaller conductors, which are then installed in parallel. This reduces the electric field strength on the conductor surface, minimizing corona losses and improving transmission efficiency and capacity.

[0031] In overhead transmission lines, crimped power fittings must withstand the full tension of the conductor or ground wire and also act as a conductor to handle overcurrent. Their quality is crucial to the safe operation of the transmission line. Furthermore, the crimping process is affected by a variety of factors, including the skill level of the construction personnel and the accuracy of the crimping equipment. This can lead to problems such as inadequate crimping and wire breakage. These issues are relatively hidden, difficult to detect through routine visual inspections, and can lead to line accidents over time.

[0032] In recent years, X-ray digital imaging inspection technology has been widely used in power transmission line inspection. X-rays have strong penetrating power and can perform comprehensive or partial inspections of tension clamps, splices, and other items without damaging the object being inspected. They can clearly reveal defects such as internal cracks, crimp deformation, and eccentricity, without affecting the normal operation of the transmission line.

[0033] However, existing inspection technologies face numerous limitations when it comes to multi-split conductors. For one thing, conventional X-ray inspection equipment is bulky and cumbersome, making it difficult to adapt to the complex spatial arrangement of multi-split conductors. This makes the inspection process labor-intensive and time-consuming to move and debug, making it extremely inconvenient. Furthermore, due to the circular arrangement of multi-split conductors, the spacing between each conductor is small, and the space is narrow, conventional inspection equipment cannot inspect multiple conductors simultaneously. This requires a one-by-one inspection process, which is not only inefficient, but also can lead to inconsistent and incoherent results due to slight deviations in equipment position during multiple inspections.

[0034] In addition, some detection technologies have problems such as detection accuracy being affected by electromagnetic interference and insufficient equipment safety performance in live working environments. They are unable to meet the efficient, accurate and safe detection needs of modern transmission lines. Innovative technologies and equipment are urgently needed to overcome these problems.

[0035] Based on this, Figure 1 As shown, a preferred embodiment of the present application is a live detection device 1 for split conductors of a transmission line, wherein several conductors 2 to be tested are arranged circumferentially. The live detection device 1 may include: a drone carrier 11, a walking mechanism 12, a X-ray machine 13 and an imaging component 14.

[0036] A through hole 1111 is provided on the drone carrier 11. The walking mechanism 12 is used to move synchronously with the drone carrier 11 along the two conductors 2 to be tested. The ray machine 13 is rotatably arranged on the drone carrier 11, and the rays emitted by the ray machine 13 pass through the through hole 1111. The rotation plane of the ray machine 13 is perpendicular to the roll axis of the drone carrier 11. The imaging component 14 includes a base 141, an annular airbag 143 and a plurality of flexible imaging plates 144. The base 141 is fixedly connected to the walking mechanism 12. The annular airbag 143 has a first inflated state and a second airless state. The annular airbag 143 is nested on the cylindrical surface of the base 141. A plurality of flexible imaging plates 144 are correspondingly fixed on the annular airbag 143. The number of the plurality of flexible imaging plates 144 is equal to the number of the plurality of conductors 2 to be tested, and the positions correspond one to one.

[0037] Among them, when the annular airbag 143 is in the second state, the imaging component 14 enters the cavity formed by the several conductors 2 to be tested from the gap of the conductor 2 to be tested. When the annular airbag 143 is in the first state, the several flexible imaging plates 144 are fitted one-to-one with the several conductors 2 to be tested. The drone carrier 11 flies outside the cavity formed by the several conductors 2 to be tested. When the drone carrier 11 is close to one of the conductors 2 to be tested, the X-ray machine 13 rotates compared to the drone carrier 11 so that the rays emitted by the X-ray machine 13 pass through the nearest conductor 2 to be tested and reach the flexible imaging plate 144 corresponding to the conductor 2 to be tested.

[0038] It is understandable that the present application does not limit the number of split conductors, as shown in the accompanying drawings of the present application. Figure 4 In the example above, six split conductors are used. In the actual solution, Figure 5 The embodiment shown uses eight split conductors or another number of split conductors, and the number of flexible imaging plates 144 can be appropriately adjusted according to the structural characteristics of the present application. Therefore, any number of split conductors is applicable to the present application, and the corresponding modified solution also falls within the scope of protection of the present application.

[0039] It is understandable that the through hole 1111 can be set on any part of the UAV vehicle 11, such as the fuselage, the arm, the battery compartment, etc. Figure 2 As shown, this application takes the body 111 as an example, and the through hole 1111 can be set on the body 111.

[0040] With this solution, when testing is required, the imaging assembly 14, equipped with the annular airbag 143 in its second, deflated state, can be lowered into the cavity formed by the multiple split conductors to be tested using a drone 11 or other tool. Simultaneously, the walking mechanism 12 can be placed on the two conductors 2 to be tested located above. After the annular airbag 143 is inflated, it pushes the corresponding flexible imaging plates 144, causing them to move from the center of the base 141 outward toward the surrounding areas, proximate to the corresponding conductors 2 to be tested.

[0041] At this time, if Figure 3 As shown, the movement of the walking mechanism 12 drives the entire imaging assembly 14 forward along the extension direction of the conductor 2 under test. The drone 11 moves circumferentially along the cavity formed by the conductors 2 under test. When a conductor 2 under test needs to be measured, the drone 11 approaches that conductor 2. The X-ray machine 13 rotates relative to the drone 11. The radiation emitted by the X-ray machine 13 passes through the nearest conductor 2 under test and reaches the flexible imaging plate 144 corresponding to that conductor 2 under test. This allows for the sequential testing of multiple, or even all, conductors 2 under test during a single mission, significantly improving detection efficiency.

[0042] In order to prevent the walking mechanism 12 from falling out, Figure 1 As shown, a wire wheel 121 and a walking rod 122 can be provided below the walking mechanism 12, wherein the wire wheel 121 is provided with an annular groove, into which one of the wires to be tested 2 is inserted, and the walking rod 122 is placed on the other wire to be tested 2.

[0043] By adopting the above solution, it is only necessary to align the walking wheel 121. The walking rod 122 can effectively contact the conductor 2 to be tested within a certain length range. It can be seen that the walking rod 122 has a natural redundant effect on the distance between the two conductors, so it is more convenient to align the walking mechanism 12 and place it on the conductor 2 to be tested.

[0044] Because the walking stick 122 has a certain length, the arrangement of the walking stick 122 is highly adaptable to variations in conductor spacing. Without requiring significant modifications to the device, it can be used with multiple split conductors of varying arrangements. This reduces the device's limitations, improves its versatility and adaptability, and broadens its application scenarios. When testing split conductors of varying spacing, even if the spacing between two adjacent test conductors 2 differs from that in another scenario, the use of the walking stick 122 allows the walking mechanism 12 to remain usable.

[0045] In one embodiment, the surface of the walking stick 122 is provided with a pattern. In the detection of overhead power lines, the surface conditions of multiple split conductors and the actual operating environment are relatively complex. The pattern on the surface of the walking stick 122 can increase the friction between the walking stick 122 and the conductor 2 to be tested.

[0046] For example, in special environments such as humidity, oil pollution, or ice, the pattern can effectively prevent the running rod 122 from slipping on the conductor 2 under test, ensuring that the live detection device 1 can move stably along the conductor 2 under test, thereby ensuring smooth detection. Even if the conductor 2 under test is tilted or vibrates, the friction provided by the pattern can ensure that the running rod 122 is in close contact with the conductor, allowing the live detection device 1 to reliably move along the conductor 2 under test, thereby improving the stability and reliability of the device during the detection process.

[0047] In an exemplary embodiment of the present application, a driving motor may be provided in the walking mechanism 12 , and the driving motor is in transmission connection with the walking wheel 121 or the walking rod 122 .

[0048] By providing a drive motor in the walking mechanism 12, the walking mechanism 12 can directly drive the imaging component 14, thereby achieving a high transmission efficiency. The drive motor can provide a stable torque output, so that the walking mechanism 12 can run smoothly, avoiding device jitter or sudden speed changes caused by unstable power. This embodiment enables the walking mechanism 12 to have the ability to operate autonomously. The staff only needs to control the drive motor to achieve the movement of the live detection device 1 on the conductor 2 to be tested, without relying on external complex traction or control equipment. This greatly simplifies the operating process, reduces the requirements for the operator's skill level, reduces the possibility of operational errors, and allows even inexperienced staff to quickly get started, thereby improving the convenience and safety of the detection work.

[0049] In another embodiment of the present application, a first traction ring may be provided on the walking mechanism 12, and a second traction ring may be provided on the UAV carrier 11, and a traction rope is connected between the first traction ring and the second traction ring.

[0050] Through the above embodiment, the first traction ring and the second traction ring enable the walking mechanism 12 to receive power from the UAV vehicle 11, thereby broadening the power source of the walking device.

[0051] The traction rope connection eliminates the need for a complex drive system within the traveling mechanism 12, simplifying its internal structure. This not only reduces manufacturing costs and processing complexity, but also makes the device lighter and more compact overall. In practical applications, the lightweight design facilitates drone loading, reduces drone load pressure, and facilitates installation, disassembly, and transportation, improving its portability and flexibility.

[0052] In actual application scenarios, the drive motor embodiment and the traction rope embodiment are not mutually exclusive, but can be organically combined to jointly serve the detection of split conductors in power transmission lines.

[0053] Because the presence of a traction rope would interfere with the drone 11 being able to circle all the conductors 2 under test, a solution driven by the power of the walking mechanism 12 itself is preferred. When the conductors 2 under test are in extreme environments, such as snowy areas or dusty and sandy environments, the walking mechanism 12 needs to overcome greater resistance. In this case, the traction rope solution can be combined with the drone 11 to increase power to successfully complete the inspection task.

[0054] Although the solution using a traction rope has certain limitations, the UAV vehicle 11 can detect each wire to be tested by repeatedly entering and exiting the cavity formed by several wires to be tested 2, and can still ensure a more efficient detection efficiency than the traditional solution.

[0055] In the embodiment of the present application, the charge detection device 1 may further include a rotation adjustment component 15 , which is fixed to the UAV carrier 11 , and the X-ray machine 13 is rotationally connected to the rotation adjustment component 15 .

[0056] Specifically, the rotation adjustment assembly 15 may include a gantry 151, a rotating sleeve 152, and a drive unit. The gantry 151 is fixed to the UAV vehicle 11 (e.g., the fuselage 111), and the gantry 151 spans the through hole 1111. The rotating sleeve 152 is mounted on the crossbeam of the gantry 151. The X-ray machine 13 is fixed to the rotating sleeve 152, and the drive unit is in transmission connection with the rotating sleeve 152.

[0057] The introduction of the rotation adjustment assembly 15 allows the operator to easily adjust the angle of the X-ray machine 13 simply by controlling the drive unit. This improvement greatly reduces the difficulty of operation, effectively reduces the angle deviation problem caused by improper operation, and improves the convenience and reliability of operation.

[0058] The use of the rotary adjustment assembly 15 enables automated angle adjustment of the X-ray machine 13 in the live detection device 1, a significant upgrade to the device's intelligence. This automated adjustment not only improves detection efficiency and accuracy but also facilitates integration with the entire detection device's control system, enabling more intelligent detection operations.

[0059] For example, a preset program can be used to enable the device to automatically adjust the angle of the X-ray machine 13 according to different detection tasks, further improving the intelligence level and automation level of the detection work and adapting to the needs of the development of modern power detection technology.

[0060] In one embodiment of the present application, the charged detection device 1 further includes an adjustable telescopic rod 142 , the base 141 and the traveling mechanism 12 are fixedly connected to the adjustable telescopic rod 142 respectively, and the adjustable telescopic rod 142 is used to adjust the distance between the base 141 and the traveling mechanism 12 .

[0061] The adjustable telescopic rod 142 makes the distance between the imaging assembly 14 and the walking mechanism 12 adjustable, which means that the charged detection device 1 can adapt to cavities of different diameters in the split conductor.

[0062] For example, when facing a split conductor composed of large-diameter wires, the adjustable telescopic rod 142 can be extended to allow the imaging component 14 to smoothly enter the larger cavity and fit with the wires; while for a split conductor composed of small-diameter wires, the adjustable telescopic rod 142 is shortened to ensure that the imaging component 14 is in a suitable position, achieving effective detection, and greatly broadening the application range of the device.

[0063] Traditional detection devices often require multiple sets of specialized equipment to accommodate split conductors of varying sizes, increasing procurement, storage, and maintenance costs. However, the live detection device 1 in this application, which utilizes an adjustable telescopic rod 142, utilizes flexible adjustment capabilities to accommodate the detection needs of multiple split conductors. This eliminates the need to purchase separate equipment for different conductor types, reducing equipment investment costs.

[0064] Not only that, in the embodiment of the present application, one end of the adjustable telescopic rod 142 is hinged to the walking mechanism 12, and the live detection device 1 can also include an angle adjuster, which can include a threaded sleeve and a screw. One end of the threaded sleeve is hinged to the walking mechanism 12, and the threaded sleeve can rotate along a preset direction compared to the walking mechanism 12, and the preset direction is the circumferential direction of the threaded sleeve.

[0065] The threaded sleeve and the adjustable telescopic rod 142 are both hinged to the traveling mechanism 12, but at different hinge locations. The other end of the threaded sleeve is threadedly engaged with one end of the screw, and the other end of the screw is hinged to the adjustable telescopic rod 142. The hinge points of the threaded sleeve and the adjustable telescopic rod 142 with the traveling mechanism 12 each form a first side. The hinge points of the adjustable telescopic rod 142 with the traveling mechanism 12 and the screw and the adjustable telescopic rod 142 form a second side. The screw and the threaded sleeve form a third side. The first, second, and third sides form a triangle. The angle formed by the first and second sides is the angle between the adjustable telescopic rod 142 and the traveling mechanism 12, and the opposite side of this angle is the third side.

[0066] By rotating the screw rod so as to change the distance between the screw rod and the threaded sleeve (ie, the length of the third side changes), the angle between the adjustable telescopic rod 142 and the walking mechanism 12 can be adjusted.

[0067] The threaded sleeve and the screw cooperate to achieve stepless adjustment of the angle between the adjustable telescopic rod 142 and the walking mechanism 12. This design allows the imaging assembly 14 to be flexibly adjusted in distance (the telescopic function of the adjustable telescopic rod 142) and accurately positioned in angle.

[0068] In order to facilitate the coordination between the threaded sleeve and the screw, other structural components may be added to the angle adjuster in this application to realize functions such as fixation and rotation. This application will not elaborate on this part of the content, and the extended solutions on this basis also fall within the scope of protection of this application.

[0069] The actual transmission line environment is complex and changeable, and conductors may present different spatial postures due to factors such as terrain and span. The angle adjuster gives the device the ability to adaptively adjust in three-dimensional space, allowing the imaging component 14 to better adapt to various unconventional detection scenarios.

[0070] In one embodiment, the charged detection device 1 may further include a plurality of counterweights, each of which has the same weight, and the plurality of counterweights are connected to the UAV carrier 11 by snapping, magnetic attraction, or bolts.

[0071] During the inspection of overhead power transmission lines, the drone carrier 11 is affected by airflow during flight, or the inspection device moves on the conductor, the X-ray machine 13 rotates, and other operations may cause the center of gravity of the device to shift. The present application effectively balances the weight of each part of the device by setting an adjustable counterweight on the walking mechanism 12 or the drone carrier 11. The counterweight is designed as a plurality of standard weight modules (such as 5g / 10g specifications), which can be installed at a specific position of the drone carrier 11 or the walking mechanism (such as the card slot under the wing) by snap connection, bolt connection or magnetic attraction. By reasonably distributing the weight, the center of gravity is lowered and shaking and vibration are reduced. For example, when performing inspection tasks in a strong wind environment, the modular counterweight system can quickly adjust the center of gravity distribution to ensure that the imaging component 14 and the conductor 2 to be tested maintain a stable relative position.

[0072] Because the counterweights are connected to the drone carrier 11 and the walking mechanism 12 using snap-on or bolt connections, workers can quickly and easily adjust the number and installation positions of the counterweights based on actual testing needs. When testing split conductors of varying sizes, or when the device needs to be inspected at different angles and heights, adding or removing counterweights and changing their installation layout allows the device's center of gravity to be precisely adjusted to accommodate diverse testing scenarios, greatly enhancing its versatility and adaptability.

[0073] Correspondingly, such as Figure 6 As shown, the present application further provides a charge detection method, which is applied to the charge detection device 1 in any embodiment of the present application. The charge detection method may include:

[0074] S101 , switching the annular airbag 143 to a first state with air, so that the plurality of flexible imaging plates 144 are fitted to the plurality of wires 2 to be tested in a one-to-one correspondence.

[0075] S102 , controlling the UAV vehicle 11 and the walking mechanism 12 to move forward synchronously.

[0076] S103 , controlling the ray machine 13 to rotate and emit rays, so that the rays pass through the wire 2 to be tested that is closest to the UAV carrier 11 and reach the flexible imaging board 144 corresponding to the wire 2 to be tested.

[0077] S104 , receiving and processing images from the plurality of flexible imaging plates 144 .

[0078] Furthermore, before switching the annular airbag 143 to the first state with air, the live detection method may also include: placing the walking mechanism 12 on the conductor 2 to be tested located above, and placing the annular airbag 143 in the second state without air in the space formed by several conductors 2 to be tested.

[0079] The working process of this application is as follows: first, the drone 11 carrying the walking mechanism 12 is controlled to fly directly above the split conductors to be tested. Then, it is controlled to slowly descend so that the wire wheels 121 and walking rods 122 on both sides of the walking mechanism 12 accurately land on the two wires 2 to be tested. At the same time, the airless imaging assembly 14 passes through the gap between the wires and smoothly enters the cavity surrounded by the wires. Then, the annular airbag 143 is inflated. After the annular airbag 143 expands, it pushes the flexible imaging plate 144 to tightly fit each wire 2 to be tested.

[0080] Subsequently, the drone 11 moves circumferentially along the cavity formed by the conductors 2 under test. The X-ray machine 13 adjusts its angle relative to the drone 11 based on the drone's position. The X-ray machine 13 emits radiation that passes through the nearest conductor 2 under test and reaches the corresponding flexible imaging board 144. The flexible imaging board 144 on the imaging assembly 14 simultaneously receives the radiation and forms a detection image. After data acquisition is complete, the image is transmitted to the backend for analysis and processing.

[0081] In summary, the embodiments of the present application provide a live detection device 1 and method for split conductors of a transmission line. The device 1 and method achieve flexible movement by combining an unmanned aerial vehicle (UAV) carrier 11 with a walking mechanism 12. By means of a rotatable X-ray machine 13 and an adaptively fitted imaging component 14, the device breaks through the limitations of traditional detection and can inspect each conductor in turn in one mission, significantly improving detection efficiency and accuracy, effectively reducing the risks and costs of manual inspection, and providing reliable guarantees for the safe and stable operation of transmission lines.

[0082] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
