Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) airborne transport equipment technology, and more specifically, to a UAV-borne wire transport and maintenance fixing device and a UAV transport system. Background Technology

[0002] As the core carrier of electrical energy transmission, the safe and stable operation of power transmission lines is directly related to national energy security and socio-economic development. To suppress corona discharge, reduce line losses, and increase transmission capacity, high-voltage and ultra-high-voltage transmission lines generally adopt split conductor structures, such as 2-split, 4-split, 6-split, or even more split conductors. Routine inspection and maintenance of these lines are crucial for ensuring the reliability of the power grid.

[0003] In recent years, drone technology, with its advantages of maneuverability, wide operating range, and no need for personnel to climb towers, has gradually replaced traditional manual tower climbing or live-line working vehicle inspection methods, becoming a core technology in the field of power transmission line operation and maintenance. Transporting maintenance equipment (such as obstacle clearing devices, withstand voltage testers, and image inspection devices) to the target conductor location via drones and ensuring reliable fixation of the equipment to the conductor is a prerequisite for achieving autonomous and precise drone-based operation and maintenance.

[0004] However, existing conductor fixing devices suitable for UAV transport still have the following technical shortcomings in practical applications: poor adaptability to split conductors: current fixing devices are mostly designed for single-specification conductors, and their clamping mechanism spacing, opening and closing dimensions, and structural layout are fixed. For conductors with different numbers of splits (such as 4-split and 6-split) or different split spacings, a single device is often not universally applicable. This not only requires power operation and maintenance units to purchase multiple models of equipment, increasing inventory costs and management difficulties, but also necessitates frequent device replacements when working on lines of different specifications, severely restricting inspection efficiency.

[0005] In summary, given the significant shortcomings in the adaptability of existing fixing devices, there is an urgent need to develop a UAV-borne conductor operation and maintenance fixing device that can adapt to conductors with different numbers of splits. This would meet the urgent needs of the power system for efficient, safe, and intelligent operation and maintenance of transmission lines, and promote the upgrading and development of transmission line operation and maintenance technology. Summary of the Invention

[0006] In view of this, the present invention proposes a UAV-borne conductor transport and maintenance fixing device and a UAV transport system, which aims to solve the problem that existing fixing devices cannot be compatible with conductors with different split spacings.

[0007] On one hand, the present invention proposes a UAV-borne wire transport and maintenance fixing device, which includes: a support carrier; at least two pairs of wire fixing plates, each pair of wire fixing plates being spaced apart on the support carrier along the width direction, and two wire fixing plates in each pair being arranged opposite to each other on both sides of the support carrier along the length direction; and a plurality of wire clamping plates arranged one-to-one with the plurality of wire fixing plates, wherein the two corresponding wire clamping plates in each pair of wire fixing plates are arranged between the two wire fixing plates in a manner that allows them to move towards each other or away from each other, for retracting into the interior of the support carrier to make way for the split wire, so that it can be placed on the inner lower side of the wire fixing plate, or extend to the outside of the support carrier and move toward the corresponding wire fixing plate, so as to clamp the split wire between the wire fixing plate and the wire clamping plate, thereby fixing the support carrier to the split wire.

[0008] Furthermore, in the aforementioned UAV-borne wire transport and maintenance fixing device, the wire clamping plate is connected to a lateral drive mechanism, which drives the two wire clamping plates corresponding to each pair of wire fixing plates to move synchronously towards each other or away from each other.

[0009] Furthermore, in the aforementioned UAV-borne cable transport and maintenance fixing device, the lateral drive mechanism includes: a drive component; and several transmission conversion components, each corresponding to one of the pairs of cable clamping plates. The power input end of each transmission conversion component is connected to the drive component, and each transmission conversion component has two power output ends, which are respectively connected to two cable clamping plates in each pair of cable clamping plates. The transmission conversion components are used to convert the output rotation of the drive component into linear motion of the two cable clamping plates in opposite directions or away from each other.

[0010] Furthermore, in the aforementioned UAV-borne cable transport and maintenance fixing device, the transmission conversion component includes: a lead screw, with a guide rail on at least one side of the lead screw; two movable plates, both of which are slidably connected to the guide rail, and both of which are spaced apart on the lead screw and threadedly connected to the lead screw to form two oppositely arranged ball screw pairs; two wire clamping plates are respectively disposed on the two movable plates, and the two movable plates are used to drive the two wire clamping plates to move towards or away from each other.

[0011] Furthermore, in the aforementioned UAV-borne cable transport and maintenance fixing device, the driving component is connected to multiple transmission conversion components via a transmission synchronization component, which drives the multiple transmission conversion components to move synchronously, thereby driving multiple pairs of cable clamping plates to move synchronously.

[0012] Furthermore, in the aforementioned UAV-borne cable transport and maintenance fixing device, the transmission synchronization component includes: a driving gear, a transmission chain, and a plurality of driven gears corresponding one-to-one with the transmission conversion component; wherein, the transmission chain is sleeved on the outer periphery of the driving gear and the plurality of driven gears, and the transmission chain meshes with the driving gear and the plurality of driven gears.

[0013] Furthermore, in the aforementioned UAV-borne wire transport and maintenance fixing device, the wire fixing plate is arranged inclined downwards along the length direction of the supporting carrier, from the outer edge of the side of the supporting carrier to the outer side away from the supporting carrier.

[0014] Furthermore, in the aforementioned UAV-borne wire transport and maintenance fixing device, the wire clamping plate is arranged parallel to the lower side of the wire fixing plate; or, the wire clamping plate is placed on the lower side of the wire fixing plate, and the distance between the wire fixing plate and the wire clamping plate gradually decreases from the connecting end of the wire fixing plate to the free end of the wire fixing plate.

[0015] Furthermore, in the aforementioned UAV-borne conductor transport and maintenance fixing device, clamping pads are provided on the opposing walls of the conductor fixing plate and the wire clamping plate for clamping onto the outer wall of the split conductor.

[0016] Furthermore, in the aforementioned UAV-borne wire transport and maintenance fixing device, the wire clamping plate is also connected to a vertical drive mechanism, which is used to drive each wire clamping plate to adjust its vertical position, so as to cooperate with the lateral movement of the wire clamping plate to clamp the split wires at different spacing positions.

[0017] On the other hand, the present invention also proposes an unmanned aerial vehicle (UAV) transport system, which is equipped with a UAV-borne wire transport and maintenance fixing device.

[0018] The UAV-borne conductor transport and maintenance fixing device and UAV transport system provided by this invention, by setting multiple pairs of conductor fixing plates arranged at intervals along the width direction, and in conjunction with retractable wire clamping plates, can flexibly adapt to conductors with different split spacings. When the wire clamping plates retract, they can provide sufficient clearance for split conductors; when the wire clamping plates extend and clamp, they can be firmly fixed to classified conductors with different spacings. One set of devices can be used for various specifications of lines such as 2-split, 4-split, and 6-split, significantly reducing equipment procurement costs and replacement frequency, and solving the problem that existing fixing devices cannot be compatible with conductors with different split spacings.

Detailed Implementation

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figures 1 to 5 This figure illustrates a preferred structure of the UAV-borne wire transport and maintenance fixing device provided in an embodiment of the present invention. As shown, the device includes: a support carrier 1, at least two pairs of wire fixing plates 2, a wire clamping plate 3, and a lateral drive mechanism 4; wherein, The support carrier 1, serving as the main support, can be fixed to the split conductor 7 via the conductor fixing plate 2 and the wire clamping plate 3 under the transport of the drone, thereby enabling the operation detection of the conductor. Specifically, the support carrier 1 can be made of lightweight, high-strength insulating material (such as carbon fiber composite material), and can be a hollow shell structure that can accommodate a control module, a battery-powered module, and a lateral drive mechanism 4, etc. The top of the support carrier 1 can be equipped with a drone mounting interface 5, such as a hook, for detachable connection with the drone's mounting device, enabling transport with the drone. In this embodiment, the support carrier 1 is equipped with several fixing nuts 11 for fastening the support carrier 1 to the internal structure to ensure reliable operation of the device during drone lifting. The drone can be a multi-rotor drone or a regular drone.

[0022] Each pair of wire fixing plates 2 is spaced apart on the support carrier 1 along the width direction, and two of the wire fixing plates 2 in each pair are arranged opposite each other on both sides of the support carrier 1 along the length direction of the support carrier 1.

[0023] Specifically, the wire fixing plate 2 is used to directly support the wire and serve as a clamping reference. In this embodiment, two pairs of wire fixing plates 2 are provided, but other numbers, such as three pairs, can also be used. The specific number is determined according to the actual situation, which can further improve the clamping stability. Each pair of wire fixing plates 2 is along the width direction of the supporting carrier 1 (e.g., ...). Figure 1 As shown in the Y-axis direction, the wire fixing plates 2 are spaced apart, with two pairs of wire fixing plates 2 respectively located at both ends of the width direction of the support carrier 1, and other pairs of wire fixing plates 2 evenly distributed between the wire fixing plates 2 at both ends. Two fixing plates in each pair of wire fixing plates 2 are arranged along the length direction of the support carrier 1 (e.g., along the Y-axis direction). Figure 1 The X-axis direction shown is arranged opposite each other on both sides of the support carrier 1 (e.g., Figure 3(As shown on the left and right sides). In this embodiment, four wire fixing plates 2 are provided, with two wire fixing plates 2 arranged on each of the left and right sides of the support carrier 1.

[0024] A preferred arrangement in this embodiment is as follows: Figure 3 As shown, along the length of the support carrier 1, from the outer edge of the side of the support carrier 1 to the outer side away from the support carrier 1, the wire fixing plate 2 is arranged obliquely downwards, as shown. Figure 3 The right-side wire fixing plate 2 is arranged inclined downwards from left to right, and the left-side wire fixing plate 2 is arranged inclined downwards from right to left. Specifically, the wire fixing plate 2 extends outwards in a cantilever shape, and its connecting end (such as...) Figure 2 The upper left end of the right wire fixing plate 2 or the upper right end of the left wire fixing plate 2 (as shown) is connected to the side of the support carrier 1, while its free end faces downward at a wide angle. This inclined design has the following functions: Firstly, when the UAV lifts the device above the target wire and lowers it, the downward-sloping guide surface can guide the split wire 7 to slide smoothly into the lower inner side of the wire fixing plate 2, playing a good guiding and clearance role and avoiding the wire from getting stuck with the edge of the fixing plate; secondly, when the clamping plate 3 clamps the wire onto the wire fixing plate 2, the downward-sloping support surface can use the component of gravity to make the wire fit more closely to the surface of the fixing plate, further enhancing the stability of the clamping and adapting to the displacement changes of the wire under galloping conditions.

[0025] Several wire clamping plates 3 are arranged in a one-to-one correspondence with multiple wire fixing plates 2. The two wire clamping plates 3 corresponding to the two wire fixing plates 2 in each pair of wire fixing plates 2 are arranged between the two wire fixing plates 2 in a manner that allows them to move towards each other or away from each other. They are used to retract into the interior of the support carrier 1 to make way for the split wire 7, so that it can be placed on the inner lower side of the wire fixing plate 2, or extend to the outside of the support carrier 1 to move towards its corresponding wire fixing plate 2, thereby clamping the split wire 7 between the wire fixing plate 2 and the wire clamping plate 3, and thus fixing the support carrier 1 to the split wire 7.

[0026] Specifically, the wire clamping plates 3 and the wire fixing plates 2 are arranged in a one-to-one correspondence. The two wire clamping plates 3 corresponding to each pair of wire fixing plates 2 are positioned between the two wire fixing plates 2 in a manner that allows them to move towards or away from each other. In particular, the side wall of the support carrier 1 is provided with clearance holes to allow for the lateral movement of the wire clamping plates 3. The wire clamping plates 3 have two working positions: in the "clearance state," the wire clamping plates 3 retract into the interior of the support carrier 1. At this time, there is a large opening space between the wire fixing plates 2 and the side wall of the support carrier 1, allowing the split wire 7 to enter this space without obstruction and be placed on the inner lower side of the wire fixing plates 2; in the case of... Figure 2In the "clamped state" shown, the wire clamping plate 3 extends and moves closer to the corresponding wire fixing plate 2 until it is as shown. Figure 2 As shown, split conductors 7 with different spacings are clamped between conductor fixing plate 2 and wire clamping plate 3, thereby reliably fixing the entire support carrier 1 to the split conductors 7. In particular, the same split conductor 7 is clamped by two or more correspondingly arranged conductor fixing plates 2 and wire clamping plates 3 on the same side of the support carrier 1. That is, the conductor fixing plates 2 and wire clamping plates 3 on both sides of the support carrier 1 are respectively clamped on the two upper split conductors 7 among the multiple split conductors 7, and two split conductors 7 with different spacings can be clamped between conductor fixing plates 2 and wire clamping plates 3. Here, the inner lower side of conductor fixing plate 2 refers to the inner side of conductor fixing plate 2 between two conductor fixing plates 2 in a pair and located below conductor fixing plate 2. As is well known to those skilled in the art, the spacing between the split conductors 7 is generally 0.3-0.5 meters (300-500 millimeters), with the specific value depending on the voltage level, the number of splits, and the line type (AC / DC). In this embodiment, the conductor fixing plate 2 has a certain structural length, enabling effective clamping of two split conductors 7 within the aforementioned typical spacing range, thereby significantly improving the device's adaptability to different split spacings. In other words, by adopting an adjustable clamping mechanism, this device can flexibly adapt to various specifications and different spacings of split conductors 7, such as 2-split, 4-split, and 6-split, and can complete cross-specification line maintenance operations without changing the device due to changes in line specifications. That is, this device is applicable to different split conductors, forming a UAV-borne conductor maintenance fixing device. This can significantly reduce the equipment procurement cost and operating time cost for power operation and maintenance units, and significantly improve overall operation and maintenance efficiency.

[0027] See also Figures 1 to 5 The wire clamping plate 3 and the wire fixing plate 2 are arranged in a one-to-one correspondence. As two preferred arrangements in this embodiment, the relative positional relationship between the wire clamping plate 3 and the wire fixing plate 2 can be as follows: Arrangement 1: The wire clamping plate 3 is arranged parallel to the lower side of the wire fixing plate 2. This parallel arrangement is simple in structure, easy to manufacture and assemble. When the wire clamping plate 3 extends and clamps, it remains parallel to the wire fixing plate 2, and can apply a uniform clamping force perpendicular to the contact surface to the wire, suitable for wire fixing under normal working conditions. Arrangement 2: As... Figure 3As shown, the clamping plate 3 is placed below the conductor fixing plate 2, and the distance between the conductor fixing plate 2 and the clamping plate 3 gradually decreases from the connecting end to the free end of the conductor fixing plate 2. In other words, the clamping plate 3 is arranged at an angle relative to the conductor fixing plate 2, forming a wedge-shaped space between them, which gradually decreases from top to bottom. When the clamping plate 3 moves towards the conductor fixing plate 2 to clamp the conductor, the gradual narrowing of the wedge-shaped space as the clamping plate 3 extends will generate a gradually increasing clamping force on the conductor, forming a self-locking effect that tightens as it clamps, which can effectively resist the pull-out force generated by the conductor due to galloping or vibration. It is particularly suitable for line sections with harsh dynamic working conditions such as heavy icing areas and strong wind areas. When the distance between the two split conductors 7 is different, the moving distance of the clamping plate 3 is different, and clamping can be achieved in both cases, especially for two split conductors 7 within a certain distance range. The two arrangement methods described above can be flexibly selected according to the actual application scenario. Both can achieve the wire clamping plate 3 retracting into the support carrier 1 in the yielding state, so that the split wire 7 can be placed on the inner lower side of the wire fixing plate 2; in the clamping state, it extends and moves closer to the corresponding wire fixing plate 2 to reliably clamp the split wire 7.

[0028] To further enhance the stability of the clamping and protect the surface of the conductor, clamping pads are provided on the opposing walls of the conductor fixing plate 2 and the wire clamping plate 3 for clamping onto the outer wall of the split conductor 7. Specifically, as follows... Figure 2 As shown, the surface of the wire fixing plate 2 facing the wire clamping plate 3 (e.g.) Figure 3 The lower inner surface shown is provided with a first clamping pad 8, and the wire clamping plate 3 faces the wire fixing plate 2 on one side surface (e.g. Figure 3 The upper surface shown is provided with a second clamping pad 9. When the wire clamping plate 3 moves closer to the wire fixing plate 2 and clamps, the split wire 7 is clamped between the first clamping pad 8 and the second clamping pad 9. The shape of the rubber pad of the rounded corner wire clamping plate 3 can be adjusted according to the wire configuration, so as to reliably hug and fit the wire without damaging it.

[0029] Preferably, both the first clamping pad 8 and the second clamping pad 9 are made of flexible materials with high friction coefficient and good insulation properties, such as rubber, polyurethane, or silicone. The use of flexible materials allows the clamping pads to undergo slight elastic deformation during clamping, thereby tightly conforming to the irregular outer surface of the conductor, increasing the contact area, improving the friction coefficient, and effectively preventing axial sliding or circumferential rotation of the conductor under clamping conditions. Simultaneously, the buffering effect of the flexible materials prevents rigid clamping from causing indentations or wear on the conductor surface, protecting the conductor from damage.

[0030] Furthermore, the surfaces of the first clamping pad 8 and the second clamping pad 9 that contact the wire can be configured as arc-shaped concave surfaces adapted to the outer surface of the wire, or they can be provided with anti-slip textures, such as wavy patterns or dotted protrusions, to further increase friction and improve clamping reliability.

[0031] By setting the aforementioned clamping pads, the device can obtain greater static friction and a more stable clamping posture when clamping the split conductor 7. Even under dynamic conditions such as the conductor being swayed by wind or dancing due to icing, it can effectively resist external disturbances and ensure that there is no relative displacement or loosening between the device and the conductor, significantly improving the safety and reliability of operation and maintenance.

[0032] See also 2 and Figure 6 To drive the movement of the wire clamping plates 3, a transverse drive mechanism 4 is connected to the wire clamping plates 3, which drives the two wire clamping plates 3 corresponding to each pair of wire fixing plates 2 to move synchronously towards each other or away from each other. Specifically, the transverse drive mechanism 4 transmits power to each pair of wire clamping plates 3 through a linkage structure, so that each pair of wire clamping plates 3 moves synchronously, so as to synchronously clamp the split wires 7 at different axial positions. This synchronous drive design can ensure that when clamping the split wires 7, multiple pairs of wire clamping plates 3 apply uniform clamping force to the wires at the same time, avoiding wire skew or unstable clamping due to one side contacting first or uneven clamping force, thereby improving the adaptability and reliability of the device under dynamic working conditions. Since the two fixing plates in each pair of wire clamping plates 3 correspond to two different split wires 7, the transverse drive mechanism 4 transmits power synchronously to these two wire clamping plates 3 through a linkage structure, ensuring that the two always maintain synchronous movement during clamping or releasing, that is, synchronous movement towards each other or away from each other. This synchronous drive design ensures that when clamping the split wires 7, the two split wires 7 corresponding to the same pair of wire fixing plates 2 are simultaneously subjected to uniform clamping force by their respective corresponding clamping plates 3. This ensures that the two split wires 7 are under consistent force, preventing the overall device from being tilted or twisted due to asynchronous movement of the clamping plates 3 on both sides. This improves the adaptability and clamping stability of the device under conditions involving multiple split wires 7. In this embodiment, as... Figure 6 As shown, the support carrier 1 may have a main support frame 12 inside, which supports the internal structure, especially the lateral drive mechanism 4. The main support frame 12 serves as the core load-bearing skeleton and can be made of lightweight, high-strength insulating materials (such as carbon fiber composites) to connect and support various functional components, ensuring the rigidity and stability of the overall structure under UAV lifting and wire clamping conditions. A base 13 may be provided on the main support frame 12 for connecting other operational loads or monitoring equipment, such as obstacle clearing devices, withstand voltage testers, and image inspection instruments. Through the standardized interface design of the base 13, the device can be quickly mounted and dismounted with various operational loads, meeting the collaborative operation needs of different transportation and maintenance tasks and expanding the functional adaptability of the device.

[0033] In this embodiment, a control module and / or communication module may be provided on the support carrier 1, especially inside it. Specifically, the control module, as the "brain" of the device, is responsible for overall coordination and command execution. The core of the control module adopts an MCU module based on the STM32 architecture. This MCU module, as the core control unit, is reliably connected to the lateral drive mechanism 4, the data monitoring module, the communication module, and the power supply module. The communication module can be a wireless communication module, used to receive remote control commands from the ground station or handheld terminal and transmit the commands to the MCU module. It can use an enhanced LoRa wireless communication method, with a communication distance of up to 200m between the two ends, achieving long-distance communication. The communication module and the MCU communicate via serial port, thereby enabling data and command transmission between the remote control and the MCU. After parsing the commands, the MCU module sends corresponding control signals to the lateral drive module, driving the lateral drive mechanism 4 to move, thereby achieving the clamping and loosening of the wire clamping plate 3, completing the automated fixing and release of the wires. To ensure the reliability of communication and anti-interference capability, such as... Figure 1 and Figure 2 As shown, the communication antenna 6 is installed on the outside of the support carrier 1, preferably on the top of the support carrier 1. This external installation method can effectively avoid the electromagnetic shielding effects of the metal components, motor drive module and power supply module inside the device body on the communication signal, ensure the signal transmission and reception quality of the communication module in a strong electromagnetic environment, realize remote communication, and thus enable ground personnel to remotely control the device to engage and disengage the wires, as well as monitor the wire status and remotely control the device load.

[0034] In this embodiment, the data monitoring module includes an accelerometer, a current sensor, a voltage sensor, and a motor encoder, which are used to collect the device's acceleration status, motor drive current, system power supply voltage, and motor speed and rotation number in real time. Acceleration data is used to monitor the device's attitude changes and movement on the conductor; current and voltage data are used to monitor the system's operating status and determine if there is an overload or power supply abnormality; motor speed and rotation number data reflect the extension and retraction position of the clamping plate 3 in real time. After the above multi-source monitoring data is transmitted to the MCU module in real time, the MCU preprocesses the data using a built-in filtering algorithm to eliminate data fluctuations caused by electromagnetic interference. The processed data is used, on the one hand, to achieve closed-loop control of the servo motor, especially the drive motor in the transverse drive mechanism 4. The MCU adjusts the drive signal in real time based on the deviation between the target position and the actual number of rotations of the motor, ensuring that the clamping plate 3 accurately reaches the preset position and maintains a stable clamping force; on the other hand, it is used for overall device status monitoring to determine whether the device is in a safe and reliable operating state.

[0035] All monitoring data is remotely transmitted. After being processed by the MCU, it is transmitted back in real time to the remote controller or ground station via the communication module, allowing operators to read and interpret the data in real time, thus enabling remote monitoring of the operation process. Simultaneously, the data storage function supports inserting an SD card into the remote controller for local storage of status monitoring data, facilitating post-operation analysis and data traceability.

[0036] The power supply module provides stable and reliable power support for the MCU and various functional modules, ensuring that the entire control system operates continuously and stably during operation.

[0037] Through the above integrated design, the MCU module coordinates all aspects such as instruction reception, motor closed-loop control, multi-source data acquisition and feedback, enabling the device to have high-precision motion control capabilities, comprehensive status perception capabilities, and remote data interaction functions, significantly improving the automation level and intelligence of operation and maintenance.

[0038] Once the drone lifts the device above the target conductor and lowers its altitude so that the conductor enters the lower side of the conductor fixing plate 2, the ground operator only needs to send a "clamp" command. The control module then controls the lateral drive mechanism 4 to move, driving the wire clamping plate 3 to extend and clamp the conductor, achieving automated installation. Disassembly is similar; sending a "release" command causes the wire clamping plate 3 to retract, detaching the device from the conductor, allowing the drone to lift and retrieve it.

[0039] In this embodiment, to further enhance the device's adaptability to wires with different numbers of splits and different split spacings, the wire clamping plate 3 is also connected to a vertical drive mechanism, which is used to drive each wire clamping plate 3 to adjust its vertical position so as to cooperate with the lateral movement of the wire clamping plate 3 to clamp the split wires 7 at different spacing positions.

[0040] Specifically, the vertical drive mechanism can be housed inside the support carrier 1. In particular, the horizontal drive mechanism 4 and the wire clamping plate 3 can be located at the power output end of the vertical drive mechanism. The clamping length of the wire clamping plate 3 is less than the clamping length of the wire fixing plate 2, and its adaptability to clamping wires with different split spacings can be further expanded through height adjustment in conjunction with horizontal position adjustment. The vertical drive mechanism 500 can take the form of a linear module, an electric push rod, or a lead screw 421 lifting mechanism, etc. Its output end is connected to the fixed end of the horizontal drive mechanism 4, enabling it to drive the horizontal drive mechanism 4 and the wire clamping plate 3 to rise or fall vertically relative to the wire fixing plate 2. Through the coordinated operation of the vertical drive mechanism and the horizontal drive mechanism 4, the wire clamping plate 3 can achieve position adjustment in a two-dimensional plane: the horizontal drive mechanism 4 controls the extension and retraction of the wire clamping plate 3 in the horizontal direction, while the vertical drive mechanism controls the height position of the wire clamping plate 3 in the vertical direction.

[0041] This dual regulatory mechanism has the following significant advantages: First, it adapts to conductors with different numbers of splits. Conductors with different numbers of splits (such as 2-split, 4-split, and 6-split) not only have different split spacings, but their relative positions in space also differ. By adjusting the vertical height of the wire clamping plate 3 through the vertical drive mechanism, the wire clamping plate 3 can be further adapted to clamp conductors with longer clamping lengths 2, enabling the clamping of conductors 7 with more split spacings, thus achieving universal adaptation of a single device for conductors with multiple numbers of splits.

[0042] Secondly, it adapts to conductor sag and installation errors. In actual lines, due to conductor sag, installation tolerances, or wind deflection, the individual conductors 7 of the same group of conductors may not be on the same strictly horizontal plane. The vertical drive mechanism can fine-tune the vertical height of the clamping plate 3 according to the actual detected conductor position, so that the clamping plate 3 is precisely aligned with the conductor, avoiding incomplete clamping or skewed force due to height deviation.

[0043] Furthermore, the yielding and clamping actions are optimized. In the yielding state, the wire clamping plate 3 can be appropriately raised through the vertical drive mechanism to provide more space for the wire to pass through into the inner side of the wire fixing plate 2; in the clamping state, the wire clamping plate 3 can be adjusted to the optimal clamping height according to the wire diameter and position to ensure that the clamping pad is in close contact with the outer surface of the wire and maximize the clamping effect.

[0044] The vertical drive mechanism is also under the unified control of the MCU module. Based on the wire position information detected by the data monitoring module, or based on preset wire specification parameters, the MCU module automatically calculates and outputs control commands to drive the vertical drive mechanism to adjust the wire clamping plate 3 to the target height, achieving fully automatic alignment and clamping. Simultaneously, the vertical drive mechanism can also be equipped with real-time feedback on the vertical position of the wire clamping plate 3, forming a closed-loop control to ensure adjustment accuracy. The position sensor can be a displacement sensor or an encoder.

[0045] By adding a vertical drive mechanism, the device of the present invention further increases the vertical adjustment capability on the basis of horizontal adjustment, realizing full adaptation to the spatial position of the split conductor 7, significantly expanding the versatility and applicability of the device, and being able to meet the operation and maintenance needs of transmission lines with different voltage levels, different number of splits, and different erection methods.

[0046] See also Figures 6 to 9 The transverse drive mechanism 4 includes: a drive component 41, several transmission conversion components 42, and a transmission synchronization component 43; wherein, several transmission conversion components 42 correspond one-to-one with each pair of wire clamping plates 3, the power input end of each transmission conversion component 42 is connected to the drive component 41, each transmission conversion component 42 has two power output ends and is respectively connected to two wire clamping plates 3 in each pair of wire clamping plates 3, and the transmission conversion component 42 is used to convert the output rotation of the drive component 41 into linear motion of the two wire clamping plates 3 towards or away from each other.

[0047] Specifically, the drive component 41, serving as the power source for the entire transverse drive mechanism 4, preferably employs a servo motor and is fixedly mounted on the base 13. Its output torque and rotation angle are precisely controlled by the MCU module according to remote control commands. Several transmission conversion components 42 correspond one-to-one with each pair of wire clamping plates 3; that is, each pair of wire fixing plates 2 corresponds to two wire clamping plates 3, each equipped with an independent transmission conversion component 42. The power input end of each transmission conversion component 42 is connected to the drive component 41, and each transmission conversion component 42 has two power output ends, which are respectively connected to two wire clamping plates 3 in each pair. Multiple transmission conversion components 42 move synchronously, realizing the synchronous movement of multiple pairs of wire clamping plates 3. The transmission conversion components 42 are used to convert the rotational motion output by the drive component 41 into the linear motion of the two wire clamping plates 3 moving towards or away from each other. The transmission conversion components 42 can adopt various structural forms to achieve the conversion of motion modes.

[0048] In this embodiment, the driving component 41 is connected to multiple transmission conversion components 42 via a transmission synchronization component 43, which drives the multiple transmission conversion components 42 to move synchronously, that is, transmits the power output by the driving component 41 to each transmission conversion component 42 synchronously and at the same speed. Specifically, the transmission synchronization component 43 is disposed between the power output end of the driving component 41 and the power input end of each transmission conversion component 42, playing a dual role of power distribution and motion synchronization. After the driving component 41 is started, its output rotational motion is first transmitted to the transmission synchronization component 43, which synchronously and at the same speed distributes the motion to each transmission conversion component 42, ensuring that no matter how many pairs of wire clamps 3 are provided in the device, all transmission conversion components 42 can simultaneously receive the same driving torque and drive their respective wire clamps 3 to move at the same speed and phase.

[0049] Through the above structural design, the transverse drive mechanism 4 achieves the following functions: After the drive unit 41 is activated, its output rotation is synchronously transmitted to the power input end of each transmission conversion component 42 via the transmission synchronization component 43. Each transmission conversion component 42 converts this rotation into two linear motion output ends with opposite directions of motion, thereby driving the two wire clamping plates 3 corresponding to each pair of wire fixing plates 2 to move synchronously towards each other (clamping) or away from each other (releasing and displacement). During this process, the actions of all pairs of wire clamping plates 3 always maintain synchronicity and consistency, ensuring that multiple positions of each type of wire are subjected to uniform and synchronous clamping force. At the same time, it ensures that each type of wire is subjected to uniform and synchronous clamping force, avoiding device tilting or uneven force on the wires due to asynchronous actions.

[0050] The transmission synchronization component 43 ensures the motion synchronization between multiple pairs of wire clamping plates 3, while the structural design of the transmission conversion component 42 ensures the motion synchronization between two wire clamping plates 3 within the same pair. This dual synchronization mechanism enables the device of the present invention to achieve coordinated and consistent action of all wire clamping plates 3 during the clamping operation of the split wire 7, significantly improving the reliability and control accuracy of the device.

[0051] In one preferred embodiment, the transmission conversion assembly 42 employs a bidirectional output gear and rack mechanism: the driving member 41 transmits power to the input gear of each transmission conversion assembly 42 via the transmission synchronization assembly 43. The rotation of the input gear drives the two racks meshing with it to move in opposite directions in a linear motion. The two racks correspond to the two wire clamping plates 3 respectively, thereby achieving synchronous approach or synchronous departure of the two wire clamping plates 3. In another preferred embodiment, the transmission conversion assembly 42 can also employ a bidirectional lead screw mechanism. The forward and reverse threaded sections of the lead screw are respectively connected to the two wire clamping plates 3, and the forward and reverse rotation of the lead screw drives the two wire clamping plates 3 to move synchronously towards or away from each other. The following is a detailed description of the lead screw mechanism structure: See also Figure 6 The transmission conversion assembly 42 includes: a lead screw 421, a guide rail 423, and two movable plates 422; wherein, the lead screw 421 is provided with a guide rail 423 on at least one side; the two movable plates 422 are slidably connected to the guide rail 423, the two movable plates 422 are spaced apart on the lead screw 421 and are threadedly connected to the lead screw 421 to form two oppositely arranged ball screw pairs, and the two wire clamping plates 3 are respectively correspondingly arranged on the two movable plates 422 to drive the two wire clamping plates 3 on the two movable plates 422 to move towards or away from each other.

[0052] Specifically, the lead screw 421, as the core component for motion conversion, has a helical structure on its outer circumference for threaded transmission engagement with the moving plate 422. The lead screw 421 is connected to the output end of the transmission synchronization assembly 43 and is driven to rotate by the drive component 41 through the transmission synchronization assembly 43. The guide rail 423 is arranged parallel to the lead screw 421, with its fixed end mounted on the main frame or base 13 of the device, providing guidance for the linear motion of the moving plate 422; there can be two guide rails 423, respectively located on both sides of the lead screw 421. The relative position of the guide rail 423 and the lead screw 421 can be such that the lead screw 421 passes through the interior of the guide rail 423. Both moving plates 422 are slidably connected to the guide rails 423, meaning that the moving plates 422 have sliders or guide holes that engage with the guide rails 423, allowing them to slide smoothly along the guide rails 423. Two movable plates 422 are spaced apart on the lead screw 421 and are threadedly connected to the lead screw 421, forming two oppositely arranged ball screw pairs. The lead screw 421 has two threaded sections with opposite directions of rotation: a left-hand thread section and a right-hand thread section. One movable plate 422 is connected to the left-hand thread section, and the other movable plate 422 is connected to the right-hand thread section. When the lead screw 421 rotates, due to the opposite directions of rotation of the two threads, the two movable plates 422 produce linear motions in opposite directions under the drive of the lead screw 421: when the lead screw 421 rotates forward, the two movable plates 422 move closer to each other (moving towards each other); when the lead screw 421 rotates in the reverse direction, the two movable plates 422 move further apart (moving away from each other). In other embodiments, the threaded holes in the two movable plates 422 have opposite thread directions, namely left-handed and right-handed threads. The lead screw 421 has two threaded sections with the same thread direction, which are threadedly connected to the left-handed and right-handed threads in the two movable plates 422, respectively. Since the threaded holes of the two movable plates 422 have opposite thread directions, the two movable plates 422 generate linear movements in opposite directions under the drive of the lead screw 421. A wire clamping plate 3 is fixedly connected to each of the two movable plates 422, that is, one wire clamping plate 3 is connected to each movable plate 422. As the movable plates 422 move towards or away from each other, the two wire clamping plates 3 move synchronously closer or farther away, thereby clamping or releasing the split wire 7. The guide rail 423 ensures that the movable plates 422 maintain a stable linear trajectory during movement, avoiding deflection or jamming of the movable plates 422 due to the tangential force generated by the threaded transmission, thus improving the smoothness of movement and transmission accuracy. Meanwhile, the use of ball screw pairs has advantages such as high transmission efficiency, smooth movement, and high positioning accuracy, which can meet the requirements for precise control of the position of the wire clamping plate 3.

[0053] Through the above structural design, the transmission conversion component 42 achieves precise conversion from the rotational motion of the lead screw 421 to the linear motion of the two wire clamping plates 3 in opposite directions / backwards, which has the following beneficial effects: Firstly, it features a compact structure and smooth transmission. The integrated design of the lead screw 421 and guide rail 423 reduces the number of parts and lowers assembly complexity; the low-friction characteristics of the ball screw pair ensure smooth transmission and efficiency.

[0054] Secondly, it offers high positioning accuracy and good controllability. The lead screw 421 transmission has a fixed lead relationship, and the moving distance of the clamping plate 3 corresponds precisely to the number of rotations of the lead screw 421, which facilitates the MCU to achieve precise closed-loop position control through the motor encoder.

[0055] Third, it has good synchronization. The two reverse threads on the same lead screw 421 ensure strict synchronization of the movement of the two moving plates 422, and the two wire clamping plates 3 can move in opposite directions or in the same direction without the need for an additional synchronization mechanism.

[0056] Fourth, it has a strong load-bearing capacity. Ball screw assemblies can withstand large axial loads, meeting the requirements for maintaining clamping force under dynamic conditions such as conductor galloping.

[0057] See also Figure 6 and Figure 9 The transmission synchronization component 43 adopts synchronous belt drive. The transmission synchronization component 43 may include: driving gear 431, transmission chain 433 and several driven gears 432 corresponding one-to-one with the transmission conversion component 42; wherein, the transmission chain 433 is sleeved on the outer periphery of the driving gear 431 and the multiple driven gears 432, and the transmission chain 433 meshes with the driving gear 431 and the multiple driven gears 432.

[0058] Specifically, the transmission chain 433 can be a synchronous belt, also known as a toothed belt, which has equally spaced teeth on its inner side. These teeth mesh with the teeth of the driving gear 431 and the driven gear 432 to achieve slip-free synchronous transmission. The driving gear 431 and the driven gear 432 are synchronous pulleys, with teeth on their outer circumference that match the tooth profile of the synchronous belt. In this embodiment, the driving gear 431 and driven gears 432 are arranged side by side, i.e., on a straight line. The motor (drive component 41) operates at a low speed, preventing the traditional problem of excessive speed difference between the gears and chain. Secondly, the intermediate driving wheel drives the two rotating wheels via the chain, ensuring power transmission and preventing slippage or jumping. Being on a straight line ensures the smoothness and reliability of the chain drive. Simultaneously, the addition or removal of pads at the bottom of the driving gear 431 ensures the tension and stability of the chain drive. The entire structure is firmly fixed, ensuring the smooth operation of the equipment's transmission and overall reliability. Furthermore, in the actual prototype, baffles and stops can be added to achieve better meshing between the chain and gears. Of course, to improve reliability, in other embodiments, the driving gear 431 and multiple driven gears 432 can also be arranged in a polygonal pattern. When the drive component 41 starts, the driving gear 431 rotates, and through the tooth meshing between the transmission chain 433 and the gears, it drives all the driven gears 432 to rotate synchronously. Because the transmission chain 433 and the gears engage in a slip-free meshing transmission, a strict speed ratio is maintained between the driving gear 431 and each driven gear 432, ensuring that all transmission conversion components 42 operate synchronously at exactly the same speed. To ensure smooth transmission and synchronization accuracy, the transmission chain 433 is preferably made of rubber or polyurethane synchronous belt, with internally embedded tensile steel wires or fiber cores to improve strength and tensile properties. Simultaneously, a tensioning device (not shown in the figure) can be installed as needed to adjust the tension of the synchronous belt, eliminate transmission backlash, and further improve synchronization accuracy.

[0059] Through the above-described synchronous belt drive structure, the transmission synchronization component 43 achieves synchronous driving of a single drive element 41 to multiple transmission conversion components 42, which has the following beneficial effects: Firstly, it has high synchronization accuracy. The tooth meshing between the synchronous belt and the pulley ensures strict synchronization between the driving gear 431 and each driven gear 432, eliminating slippage and ensuring that all transmission conversion components 42 operate at exactly the same speed and phase.

[0060] Secondly, it offers smooth transmission and low noise. Synchronous belt drives have damping and vibration absorption capabilities, resulting in lower noise during transmission, making them suitable for precision control scenarios where high operational stability is required.

[0061] Third, it features a flexible layout and compact structure. The synchronous belt can be flexibly routed according to the actual structural layout, adapting to the space constraints inside the support carrier 1, and facilitating the centralized drive of multiple sets of transmission conversion components 42.

[0062] Fourth, it requires no lubrication and is easy to maintain. Synchronous belt drives do not require lubricating oil, avoiding potential pollution of power transmission lines by lubricating oil, and are simple to maintain, making them suitable for field operations.

[0063] In other embodiments, the transmission synchronization component 43 may also take the form of gear transmission or linkage transmission.

[0064] How to operate the device: Before the operation begins, the drone, carrying the mounting ring, attaches to the drone mounting interface 5 of the device. The drone is then controlled to transport the device above the multi-split conductor 7, ensuring that the two upper conductors of the multi-split conductor 7 are positioned on the lower sides of the conductor fixing plates 2 on either side. Subsequently, ground personnel send a remote command via remote controller to activate the lateral drive mechanism 4, which drives the wire clamping plate 3 to move towards the conductor fixing plate 2, precisely locking the conductors. After locking, the drone detaches from the device and flies back to the ground, while the device remains fixed to the conductor to perform maintenance or monitoring tasks. After the task is completed, the drone flies back above the device and attaches again. The remote controller sends a release command, causing the wire clamping plate 3 to retract, separating the device from the conductor. The drone then carries the device back to the ground, completing the operation.

[0065] In summary, the UAV-borne conductor transport and maintenance fixing device provided in this embodiment, by setting multiple pairs of conductor fixing plates 2 spaced apart along the width direction, and in conjunction with the retractable wire clamping plate 3, can flexibly adapt to conductors with different split spacings. When the wire clamping plate 3 retracts, it can provide sufficient clearance for the split conductors 7; when the wire clamping plate 3 extends and clamps, it can be firmly fixed to the conductors of each category. One set of devices can be used for various specifications of lines such as 2-split, 4-split, and 6-split, which significantly reduces equipment procurement costs and replacement frequency, and solves the problem that existing fixing devices cannot be compatible with conductors with different split spacings.

[0066] Furthermore, the wire clamping plate 3, actively controlled by the transverse drive mechanism 4, cooperates with the fixed wire fixing plate 2 to form an active clamping structure. Compared with the traditional passive spring clamping, the clamping force is greater and adjustable. Even if the wire dances or swings, the drive mechanism can maintain a stable clamping force, effectively preventing the equipment from loosening or falling off, and significantly improving the safety of operation and maintenance. In particular, the use of servo motor closed-loop control ensures that the device maintains a stable clamping force under different operating conditions, further avoiding line faults or equipment damage caused by the equipment falling off, and ensuring the safety and testing accuracy of operation and maintenance.

[0067] Meanwhile, by integrating a control system and wireless communication module, the device can be remotely and controllably installed and dismantled. The drone is only responsible for transporting the equipment to the target location, eliminating the need for pilots to perform complex micro-management and mounting. The installation process can be completed with a single remote command, reducing manual intervention and enabling the effective completion of subsequent auxiliary testing and maintenance tasks. This not only reduces reliance on pilot skills but also improves the success rate of operations in complex environments and overall inspection efficiency. The device is adaptable to the operation and maintenance scenarios of different split conductors in UHV transmission lines, providing core fixed support for the autonomous and intelligent operation and maintenance of drones. This helps the power system build an efficient, safe, and low-cost transmission line operation and maintenance system, meeting the national power system's operation and maintenance needs as it develops towards UHV and intelligent systems, and promoting the upgrading and iteration of transmission line operation and maintenance technology.

[0068] System Implementation Example: This embodiment also proposes a drone transport system, which is equipped with the aforementioned drone-borne wire transport and maintenance fixing device. The specific implementation process of the drone-borne wire transport and maintenance fixing device is described above and will not be repeated here. In other words, the drone transport system may include a drone body and a drone-borne wire transport and maintenance fixing device; wherein, the drone body is provided with a hanging ring for attaching the drone mounting interface 5, that is, the drone mounting interface 5 is attached to the hanging ring on the drone body.

[0069] Since the UAV-borne conductor transport and maintenance fixing device has the above-mentioned effects, the UAV transport system with the UAV-borne conductor transport and maintenance fixing device also has the corresponding technical effects.
