Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a power distribution network cable inspection device. Background Technology

[0002] The power distribution network is a crucial link connecting users in the power system, and the stable operation of its cable lines directly affects the reliability of power supply. With the advancement of smart grid construction, the use of automated equipment for cable inspection has become a mainstream trend. Currently, the use of drones for cable inspection is a widely researched and applied technology in the industry.

[0003] Drone inspection technology, equipped with high-definition visible light cameras and infrared thermal imagers, can quickly cover large areas of cable lines, effectively reducing the labor intensity of manual inspections and improving inspection efficiency. However, in practical applications, this technology still suffers from a series of inherent and difficult-to-overcome technical defects, specifically as follows: To achieve effective monitoring, drones must continuously fly above the cable path, consuming significant amounts of electrical energy to maintain attitude and position. This continuous flight operation results in enormous power consumption, typically limiting a single flight to 20-30 minutes. For long-distance cable line inspections, frequent takeoffs and landings for battery replacements are necessary, severely hindering inspection efficiency and increasing maintenance and time costs.

[0004] To ensure flight safety and avoid collisions between drones and cables, towers, and other infrastructure (i.e., "drone crashes"), drones must maintain a sufficiently large safety distance from cables. However, this safety distance directly increases the physical distance between the monitoring equipment and the cable target, resulting in decreased image resolution. Minor defects (such as surface cracks on insulators, slight corrosion of hardware, and small foreign objects) are difficult to detect clearly, thus reducing the accuracy of monitoring and the ability to provide early warning of faults.

[0005] Because drones typically fly above or to the side of power cables, their onboard camera sensors primarily use a top-down or oblique view. Consequently, critical areas such as the cable's underside, bottom fittings, and connection points are completely obscured and cannot be monitored. These areas are precisely where moisture and dust easily accumulate, leading to corrosion or overheating. For complex three-dimensional components like cable joints and suspension points, a single viewpoint cannot provide a comprehensive assessment of their condition, leaving significant safety hazards. Summary of the Invention

[0006] This invention provides a power distribution network cable inspection device, which can solve the following problems existing in the prior art: 1) There is a prominent contradiction between endurance and patrol energy consumption; 2) Safe flight distance and monitoring clarity are mutually restrictive; 3) There are unavoidable monitoring blind spots.

[0012] Preferably, the limiting wheel has an arc-shaped groove on its wheel body for embedding the cable body.

[0013] Preferably, a limiting seat is rotatably arranged on the drive shaft, one side of the limiting seat is fixedly connected to the second guide rod, and the other end of the second guide rod is slidably inserted into the second sleeve.

[0014] Preferably, both the upper monitoring module and the lower detection module are rotatably mounted on the drive shaft, and the upper monitoring module and the lower detection module are fixed by a connecting bracket; The upper monitoring module is fixedly connected to the limiting seat.

Several sets of strip-shaped slots are arranged in a circumferential array inside the limiting sleeve. A locking rod is fixedly arranged at the axis of the toothed ring. Several sets of strip-shaped locking seats that slide and engage with the strip-shaped slots are fixedly arranged on the locking rod.

[0016] Preferably, the rotating mechanism includes a rack that meshes with the first gear.

[0017] This invention provides a power distribution network cable inspection device, which has the following beneficial effects: 1) When the monitoring drone of the present invention moves along the cable body, it can simultaneously drive the upper monitoring module and the lower detection module to move. The cable body is located in the middle of the upper monitoring module and the lower monitoring module, so that the upper half and the lower half of the cable body can be monitored simultaneously, making the monitoring range more comprehensive. 2) Compared to existing technologies where drones must maintain a continuous flight attitude to move along the cable's path, this invention significantly reduces energy consumption through a "cable-walking" mode. This is because the power required for the drive wheels to move is far lower than the power required to drive the rotors to maintain flight. Therefore, when the dual-head motors are driving the movement, their operating speed and output power are much lower than in flight mode, resulting in significant energy savings and extending the equipment's single-operation time.

[0018] 3) In this invention, because the device is directly attached to the cable body via the limiting wheels, it achieves close, or even zero-distance, contact with the cable body. This completely eliminates the image blurring problem caused by maintaining a safe distance, enabling the monitoring module to acquire extremely high-definition images and data; thus, it allows for a comprehensive, blind-spot-free inspection of the cable's lower surface, side surface, and other previously unmonitored areas, greatly improving the comprehensiveness and reliability of the inspection.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1

[0023] like Figures 1 to 3As shown in the figure, the present invention provides a power distribution network cable inspection device, including a monitoring drone 1; specifically, this embodiment uses the monitoring drone 1 to monitor the power distribution network cables, thereby enabling remote monitoring of high-altitude cables, effectively improving safety and efficiency.

[0024] In this embodiment, the monitoring drone 1 includes a main structure 101, with two sets of frames 102 symmetrically fixed on both sides of the main structure 101. A dual-head motor 103 is fixedly mounted at the end of the frame 102, and a rotor 104 is fixedly mounted on the dual-head motor 103. Specifically, when the monitoring drone 1 takes off, the rotor 104 can be driven to rotate by each dual-head motor 103. This is existing technology, and this embodiment will not elaborate on it.

[0025] As one embodiment of this invention, two sets of limiting wheels 5 are symmetrically arranged on both sides of the main structure 101. The wheel body of the limiting wheel 5 is provided with an arc-shaped groove 501 for embedding into the cable body 2. Each set of limiting wheels 5 is also rotatably provided with a drive wheel 402 for rolling contact with the side edge of the cable body 2. Each drive wheel 402 is fixed to the other end of the dual-head motor 103 through a transmission module. It can be noted that when the monitoring drone of this embodiment is used, the main structure 101 can be lifted above the two sets of adjacent cables to be monitored. Then, the limiting wheels 5 on both sides are adjusted to overlap the cable body 2. After the overlap is completed, each drive wheel 402 rolls against the side edge of the cable body 2. Then, the dual-head motor 103 can drive the drive wheel 402 to rotate through the transmission module. Based on the friction between the drive wheel 402 and the side edge of the cable body 2, the effect of driving the main structure 101 to move along the cable body 2 can be achieved. In addition, in order to increase the friction between the drive wheel 402 and the cable body 2, protrusions are evenly provided on the wheel body of the drive wheel 402 to ensure that the drive wheel 402 can stably drive the monitoring drone 1 to move along the cable body 2.

[0026] As a further embodiment, an adjustment module is also included, which is used to adjust the distance between the two limiting wheels 5; it can be explained that, based on the different distances between the two sets of adjacent cable bodies 2, Specifically, when monitoring the drone 1 as it moves along the cable body 2, in order to monitor the cable body 2, please refer to... Figure 1 as well as Figure 4Each drive wheel 402 has an upper monitoring module 4 and a lower monitoring module 401 symmetrically arranged on one side in the vertical direction. It can be explained that when the monitoring drone 1 in this embodiment moves along the cable body 2, it can simultaneously drive the upper monitoring module 4 and the lower monitoring module 401 to move. The cable body 2 is located in the middle of the upper monitoring module 4 and the lower monitoring module 401, so that the upper half and the lower half of the cable body 2 can be monitored simultaneously, making the monitoring more comprehensive.

[0027] Based on this, in this embodiment, when a detailed inspection of the cable body 2 is required, the flight system of the monitoring drone 1 can be used for initial positioning, and the limiting wheels 5 on both sides can be smoothly placed on the target cable. Subsequently, the control system switches the power mode, and transmits the power generated by the dual-head motor 103 to the drive wheel 402 through the transmission module, driving the drive wheel 402 and the limiting wheels 5 to move along the cable body 2, thus moving the entire device.

[0028] Compared to existing technologies where drones must maintain a continuous flight attitude to move along the path of the cable body 2, this invention significantly reduces energy consumption through a "cable-walking" mode. This is because the power required for the drive wheels 402 to move is far lower than the power required for the drive rotors 104 to maintain flight. Therefore, when the dual-head motors 103 are driving the movement, their operating speed and output power are much lower than in flight mode, thus achieving significant energy savings and extending the single-operation time of the equipment.

[0029] Furthermore, because the device is directly attached to the cable body 2 via the limiting wheel 5, it achieves close or even zero-distance contact with the cable body 2. This completely eliminates the image blurring problem caused by maintaining a safe distance, enabling the monitoring module to acquire extremely high-definition images and data; thus, it allows for a comprehensive inspection of the cable's lower surface, side surface, and other previously blind spots, greatly improving the comprehensiveness and reliability of the inspection.

[0030] Example 2

[0031] Based on Example 1, please refer to Figures 1-2 as well as Figures 4-6 The main structure 101 is also equipped with an adjustment module, which is used to drive the two drive wheels 402 to move closer to each other or further apart. It can be explained that, by setting an adjustment module, based on the different spacing between two adjacent sets of cable bodies 2, this embodiment can adaptively adjust the spacing between the two drive wheels 402 on both sides through the adjustment module, and synchronously drive the limit wheel 5 to move, so as to ensure that the limit wheel 5 can be placed on the cable body 2.

[0032] For guidance and support of limit wheel 5, please refer to Figure 1 , Figures 5-8The main structure 101 has a positioning hole 108, and an adjusting rod 109 is slidably inserted into the positioning hole 108. A limiting plate 110 with a diameter larger than the positioning hole 108 is fixedly arranged at the top of the adjusting rod 109. The other end of the adjusting rod 109 is fixedly connected to the base plate 105. A first sleeve 602 is fixedly arranged on the base plate 105. A first guide rod 603 is slidably inserted at both ends of the first sleeve 602. The end of the first guide rod 603 away from the first sleeve 602 is fixed to the limiting plate 502. The limiting wheel 5 is rotatably arranged on the limiting plate 502. It can be noted that in this embodiment, when adjusting the distance between the two limiting wheels 5, the two limiting wheels 5 drive the first guide rod 603 to extend and retract in the first sleeve 602 through the limiting plate 502, so as to improve the stability of the movement of the limiting wheel 5 and play a guiding and limiting role.

[0033] In one embodiment of this invention, the adjustment module includes a drive shaft 304 fixed to the drive wheel 402, a swing plate 302 rotatably mounted on the drive shaft 304, and a first gear 301 fixedly mounted at the other end of the swing plate 302. The first gear 301 is connected to a rotation mechanism that drives its rotation. It can be noted that in this embodiment, when adjusting the two drive wheels 402 to move closer together or further apart, the first gear 301 can be driven to rotate by the rotation mechanism. During the rotation of the first gear 301, the movement of the drive shaft 304 can be adjusted by the swing plate 302 (see reference). Figure 3 This allows for the simultaneous adjustment of the distance between the two drive wheels 402, enabling the two drive wheels 402 to roll and contact the side edges of the cable body 2.

[0034] Furthermore, in this embodiment, the flight control system of the monitoring drone 1 is communicatively connected to the adjustment module. A pressure sensor is provided where the drive wheel 402 contacts the cable body 2, and / or a current detection unit for monitoring its operating current is provided at the power output end of the adjustment module; the signal output ends of the pressure sensor and / or the current detection unit are connected to the flight control system.

[0035] For example, when the drone flies to the area of ​​the target dual cable body 2 and hovers initially, the control system activates the adjustment module to drive the drive wheels 402 on both sides to extend outward away from the main structure 101.

[0036] Scenario 1 (Ideal): If the initial position of the monitoring drone 1 is basically centered, the two drive wheels 402 will extend synchronously and contact the side edges of the two cable bodies 2 almost simultaneously. When the pressure sensor detects the contact pressure signal and / or the current detection unit detects a significant increase in the load current of the drive motor, the flight control system determines that the drive wheels 402 have made reliable contact with the cable bodies 2, and then controls the adjustment module to stop moving. At this time, the monitoring drone 1 is precisely confined to the symmetrical center line of the two cable bodies 2.

[0037] Scenario 2 (Non-ideal): If the initial position of the monitoring drone 1 is biased to one side, the drive wheel 402 on that side will contact the cable first. Since the monitoring drone 1 is in a hovering state, its flight control system will try to maintain the current position. At this time, the reaction force of the positioning rod that first contacts the cable body 2 will act as a continuous external force on the main structure 101. As the adjustment module continues to drive the two drive wheels 402 to move in opposite directions, this reaction force will push the main structure 101 towards the other side of the cable body 2 until the drive wheel 402 on the other side also contacts the cable body 2. When the flight control system determines through sensor signals that both drive wheels 402 have contacted the cable body 2, it immediately stops the adjustment module, thereby completing the automatic centering adjustment of the monitoring drone 1.

[0038] This implementation method achieves fully automated positioning of the UAV between two cables, eliminating the need for manual fine-tuning and reducing operational difficulty and technical dependence. Through the synergistic effect of mechanical limit and flight control, it achieves high centering accuracy and good reliability, laying a solid foundation for subsequent precision operations. It can adapt to different initial position deviations and automatically complete the entire process of correction and centering. The device has a simple structure, is easy to implement, and ensures the accuracy of the action and system safety through dual judgment by sensors.

[0039] Specifically, in this embodiment, when the adjustment module drives the two drive wheels 402 to move, in order to achieve the effect of synchronously adjusting the movement of the limiting wheel 5, a limiting seat 405 is rotatably arranged on the drive shaft 304. One side of the limiting seat 405 is fixedly connected to the second guide rod 403, and the other end of the second guide rod 403 is slidably inserted into the second sleeve 505. It can be explained that in this embodiment, when the swing plate 302 drives the drive shaft 304 to swing, it can synchronously drive the second guide rod 403 to extend and retract in the second sleeve 505. At the same time, the limiting plate 502 synchronously drives the first guide rod 603 to extend and retract in the first sleeve 602, so that during the movement, the amount of change in the distance between the two limiting wheels 5 is consistent with the amount of distance between the two drive wheels 402. When the drive wheel 402 abuts against the cable body 2, the limiting wheel 5 moves just above the cable body 2, avoiding misalignment.

[0040] It should also be noted that both the upper monitoring module 4 and the lower monitoring module 401 are rotatably mounted on the drive shaft 304, and the upper monitoring module 4 and the lower monitoring module 401 are fixed by the connecting bracket 404. The upper monitoring module 4 is fixedly connected to the limiting seat 405. Specifically, when the drive shaft 304 rotates in this embodiment, the relative positions and angles of the upper monitoring module 4, the lower monitoring module 401 and the limiting seat 405 remain unchanged, thereby enabling comprehensive monitoring of the cable body 2.

[0041] In one embodiment of this invention, after the drive wheel 402 abuts against the cable body 2, in order to drive the monitoring drone 1 to move along the cable body 2 via the drive wheel 402, the transmission module includes a second gear 303 fixed on the drive shaft 304. The second gear 303 meshes with a gear ring 3, and the gear ring 3 is rotatably mounted on the first gear 301. A third guide rod 504 is fixedly connected to the end of the first gear 301 away from the gear ring 3. Two guide rods 504 are symmetrically fixed on both sides of the bottom of the main structure 101. An L-shaped bracket 506 is assembled, with a third sleeve 503 fixedly arranged at its end, which slides into the third guide rod 504. A limiting sleeve 106 is fixedly arranged at the end of the dual-head motor 103 away from the rotor 104. Several sets of strip-shaped slots 107 are arranged in a circumferential array inside the limiting sleeve 106. A locking rod 305 is fixedly arranged at the axis of the toothed ring 3, and several sets of strip-shaped locking seats 306 are fixedly arranged on the locking rod 305, which slide into the strip-shaped slots 107. It can be noted that in the initial state... At this time, the lever 305 and the limiting sleeve 106 are in a separated state. When the two drive wheels 402 abut against the cable body 2, the flight control system adjusts the main structure 101 to descend until the arc groove 501 on the limiting wheel 5 is engaged with the cable body 2. The flight control system adjusts the rotor 104 to decelerate and keep the angle consistent. Under the action of gravity, the main structure 101 continues to descend until the lever 305 is inserted into the limiting sleeve 106 and the strip-shaped card seat 306 is engaged with the strip-shaped card groove 107. When the rotor 104 continues to rotate, the lever 305 can be driven to rotate through the limiting sleeve 106. The lever 305 drives the gear ring 3 to rotate. The gear ring 3 can drive the drive shaft 304 to rotate by meshing with the second gear 303. In this embodiment, there is no need to set up other servo drive equipment to adjust the rotation of the drive wheel 402. The drive wheel 402 can be driven to rotate under the cooperation of the flight system and the transmission module. This not only reduces the cost but also reduces the weight of the monitoring drone 1, further improving the endurance of the equipment.

[0042] In addition, the drive wheel 402 in this embodiment needs to be provided with a certain length in the axial direction to ensure that the drive wheel 402 can stably abut against the cable body 2.

[0043] For details, please refer to Figure 1 as well as Figures 5-8The rotating mechanism of this embodiment includes a rack 604 meshing with the first gear 301. The rack 604 is fixedly connected to a support plate 6 slidably mounted on the base plate 105 via a support rod 601. Baffles 7 are fixedly mounted on both sides of the base plate 105. A support shaft 701, fixedly connected to the support plate 6, is slidably inserted into the baffle 7. A telescopic spring 702 is mounted on the support shaft 701. One end of the telescopic spring 702 is fixedly connected to the baffle 7, and the other end is fixedly connected to the support plate 6. A wedge-shaped plate 703 is fixedly mounted on the side of the two support plates 6 that are close to each other. Inclined guide surfaces 704 are provided on the same side of both sets of wedge-shaped plates 703. An electric cylinder 705 is also fixedly mounted on the base plate 105. The driving end of the electric cylinder 705 is symmetrically mounted with two sets of guide wheels 706 that roll against the inclined guide surfaces 704 on both sides. It can be noted that in the initial state, based on the telescopic spring 70... With configuration 2, the two side support plates 6 are positioned close to each other, and the distance between the two drive wheels 402 is minimized. When it is necessary to adjust the distance between the two drive wheels 402, the electric cylinder 705 first drives the two guide wheels 706 to move. The guide wheels 706 roll against the inclined guide surface 704, driving the two wedge plates 703 to move away from each other, so as to simultaneously compress the telescopic spring 702 and generate elastic force. The wedge plates 703 drive the rack 604 to move through the support plate 6 and the support rod 601. The rack 604 then drives the first gear 301 to rotate. During the rotation of the first gear 301, the drive shaft 304 can be adjusted by the swing plate 302. Based on this, this embodiment only needs to set one set of electric cylinders 705 to achieve the effect of synchronous adjustment of the synchronous movement of each drive wheel 402, which not only reduces the cost but also ensures the synchronicity and stability of each drive wheel 402.

[0044] A method for inspecting power distribution network cable inspection equipment includes the following steps: Please see Figures 1-4 S1. When performing a detailed inspection of the cable body 2, the flight system of the drone 1 is monitored for preliminary positioning, and the limiting wheels 5 on both sides are smoothly placed on the target cable. S2. The control system switches the power mode and transmits the power generated by the dual-head motor 103 to the drive wheel 402 through the transmission module, which drives the drive wheel 402 and the limit wheel 5 to move along the cable body 2, thus moving the entire equipment. S3. When the monitoring drone 1 moves along the cable body 2, it synchronously drives the upper monitoring module 4 and the lower detection module 401 to move. The cable body 2 is located in the middle of the upper monitoring module 4 and the lower monitoring module 401, and the upper and lower halves of the cable body 2 are monitored synchronously.

[0045] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
