Description

Technical Field

[0001] This utility model relates to the field of power operation and maintenance equipment technology, and in particular to a high-voltage line anti-strand scattering device based on a drone. Background Technology

[0002] During the operation and maintenance of high-voltage transmission lines, conductors are prone to loosening, loose twisting, or single-strand breakage due to long-term exposure to wind vibration, ice loads, and thermal expansion and contraction. To prevent further spread of loose strands and the occurrence of phase-to-phase short circuits or conductor breakage accidents, it is usually necessary to reinforce or rewrap the loose strands between towers. In existing technologies, manual tower climbing or mechanical clamps with insulated telescopic poles are often used to assist in the installation. The clamping and reinforcement operation is completed by workers approaching the high-voltage line.

[0003] However, the above-mentioned manual or ground-assisted installation methods have several shortcomings: First, manual tower climbing near live lines is risky, with strict requirements on ambient wind speed, line voltage level, and safety distance, making safety protection difficult; Second, the operation of insulating poles is not precise enough under the influence of high-altitude winds, and the clamps are difficult to accurately position at the point of strand breakage; Third, existing anti-strand breakage clamps usually require manual force to close or screw and lock, and cannot achieve automatic clamping and fixing in remote environments, resulting in low operating efficiency and unsuitability for rapid emergency response.

[0004] Therefore, there is an urgent need for a technical solution that can clamp and fix loose strands of wire without direct contact with high-voltage lines, and that has the structural characteristics of being able to be remotely deployed by drones and automatically complete the clamping action, thereby realizing safe, intelligent and rapid operation of high-voltage lines to prevent loose strands. Utility Model Content

[0005] This utility model aims to provide a high-voltage line anti-stranding device based on unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art. This solution combines UAV technology with a mechanical self-locking clamp structure to form a remotely deployable high-voltage line anti-stranding device, achieving non-contact automatic reinforcement of high-altitude conductors. The device adopts a separable base and clamp design. Utilizing the clamping force provided by a torsion spring and the linkage trigger mechanism, the clamp automatically closes the moment the conductor comes into contact, completing conductor clamping without manual intervention. The cooperation of the guide plate and limit block structure automatically centers the conductor and ensures stable clamping direction, significantly improving the fault tolerance and capture success rate of UAV aerial operations. The base can automatically detach from the clamp after triggering, allowing the UAV to safely evacuate without touching the high-voltage line. Through the above structural design, this device effectively reduces the risk of live line maintenance, improves emergency response efficiency, and possesses beneficial effects such as lightweight structure, high operational reliability, excellent safety, and high level of intelligence.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figure 1-4 The high-voltage line anti-strand device based on a drone shown includes:

[0027] The base 1 has a connecting rod 3 connected to its top end, and a pair of slots 2 are provided on the outer end of the base 1.

[0028] The first clamping block 4 and the second clamping block 5 are arranged opposite to each other and rotatably connected. The first clamping block 4 is connected to both ends of the mounting post 6. The first clamping block 4 and the second clamping block 5 are connected to both ends of the limiting post 7. The outer end of the mounting post 6 is fitted with a torsion spring 8. The two ends of the torsion spring 8 are respectively attached to a pair of limiting posts 7 located on the same side of the first clamping block 4 and the second clamping block 5.

[0029] The first link 10 and the second link 11 are rotatably connected to the first clamping block 4 and the second clamping block 5, respectively. The first link 10 and the second link 11 are rotatably connected and are arranged opposite to each other. The top of the first link 10 and the second link 11 are integrally formed with a locking block 13, which matches the locking groove 2. The bottom of the first link 10 and the second link 11 extends to the lower side of the first clamping block 4 and the second clamping block 5.

[0030] In this embodiment, the base 1 is a connecting component of the drone mounting structure. It is connected to the gimbal below the drone via a quick-release structure through a connecting rod 3. The base 1 is made of lightweight and high-strength aluminum alloy to reduce the load weight of the drone. The outer ends of the base 1 are provided with slots 2 on both sides to form a temporary locking structure with the locking block 13, so that a detachable connection with the base 1 can be achieved when the clamp is pried open.

[0031] The first clamping block 4 and the second clamping block 5 are the main clamping mechanisms, and the two are symmetrically rotated and connected by a rotating shaft; the torsion spring 8 sleeved on the mounting column 6 provides clamping force, so that the two blocks are in a closed state in their natural state.

[0032] Each clamping block is connected to a limit post 7 at both ends, and the two ends of the torsion spring 8 are respectively attached to the limit post 7. The clamping strength is controlled by changing the preload of the torsion spring.

[0033] The first link 10 and the second link 11 form a linkage triggering mechanism. They are respectively connected to a corresponding pair of rotatable parts, so that they maintain synchronous movement during opening and closing actions.

[0034] When the device is in use, the operator pries open the two clamping blocks, causing the first connecting rod 10 and the second connecting rod 11 to rotate, so that the locking block 13 is inserted into the locking groove 2 of the base 1, thereby fixing the clamp to the drone base. When the drone flies to the point where the high-voltage line is unstretched, when the wire enters the inside of the clamp and abuts the lower end of the first connecting rod 10 and the second connecting rod 11, the connecting rod is pushed away from the locking groove 2. At the same time, the torsion spring 8 releases its elastic force, so that the clamp quickly clamps the wire to achieve anti-unstretching fixation. At this time, the base 1 and the clamp automatically separate, and the drone can be safely withdrawn.

[0035] Guide plates 9 are connected to the bottom ends of both the first clamping block 4 and the second clamping block 5.

[0036] In this embodiment, the guide plate 9 is an auxiliary wire-entry structure, fixedly installed at the bottom of the clamping block. Its main function is to form a V-shape or flared opening to guide the high-voltage wire smoothly into the clamp when the device falls close to the wire. The guide plate 9 is made of insulating nylon to prevent arc breakdown. With the setting of the guide plate 9, even if the UAV attitude is slightly deviated, the wire can still be guided to the effective clamping area below the connecting rod, significantly improving the wire capture success rate.

[0037] A pair of guide plates 9 are arranged symmetrically at an angle, and the distance between the pair of guide plates 9 increases from top to bottom.

[0038] In this embodiment, the upper end of the guide plate 9 has a small spacing and the lower end has a large spacing, forming a trumpet-shaped guide opening structure. During the descent of the UAV and its approach to the wire, the wire first contacts the inner wall surface of the guide plate, and then slides along the inclined surface between the clamping blocks. This symmetrical tilt design not only serves as a guide, but also generates a small guiding force at the moment of contact with the wire, causing the wire to automatically center in the center of the clamp, facilitating balanced force distribution on the linkage mechanism and improving the clamping success rate.

[0039] A reserved groove 12 is provided at the center of one end of the first clamping block 4 and the second clamping block 5 that are close to each other, and the first connecting rod 10 and the second connecting rod 11 are both located inside the reserved groove 12.

[0040] In this embodiment, the reserved slot 12 is used to accommodate and protect the first connecting rod 10 and the second connecting rod 11, so that they are not exposed when the clamp is closed, thus avoiding external interference and insulation damage.

[0041] Both the first link 10 and the second link 11 are designed with an L-shaped structure.

[0042] In this embodiment, the L-shaped structure design allows the connecting rod to form a significant lever arm difference during movement. When the wire presses against the vertical part of the connecting rod, the connecting rod will achieve a large angle rotation with a small triggering force, thereby effectively releasing the locking state of the bottom locking block 13 and the locking groove 2. This L-shaped connecting rod not only enhances the action sensitivity, but also ensures smooth triggering action and a compact and stable mechanical structure through the coaxial design of the rotating shaft and the clamping block.

[0043] Mounting post 6 is coaxially arranged with the rotation axis of the first connecting rod 10 and the second connecting rod 11.

[0044] In this embodiment, through the coaxial design, the torque of the torsion spring 8 can be directly applied to the linkage hinge point when the clamp is opened and closed, thereby ensuring that the linkage action is synchronized and the response is rapid at the moment of triggering, while reducing the size of the device and making it easier for the UAV to be mounted and deployed.

[0045] One end of the first link 10 is integrally formed with a limiting block 14, which abuts against the second link 11 to limit the rotation direction of the first link 10 and the second link 11.

[0046] In this embodiment, the limiting block 14 is used to ensure that the connecting rod rotates only within a specified angle range. When the limiting block 14 abuts against the second connecting rod 11 to form a physical stop, it forms a limiting relationship with a pair of clamping blocks, keeping the pair of clamping blocks in an open state. This limiting structure improves the reliability of the mechanism and prevents repeated clamping or malfunction.

[0047] Positioning blocks 15 are connected to the bottom of both ends of the base 1. The bottom of the positioning blocks 15 has an arc-shaped structure that matches the mounting column 6.

[0048] In this embodiment, the arc-shaped bottom surface of the positioning block 15 can fit with the mounting column 6 to improve assembly stability. During the takeoff of the UAV, the positioning block 15 can prevent the fixture from swinging and shifting. When the wire triggers the connecting rod, the locking block 13 disengages from the slot 2. Under slight vibration, the positioning block 15 can automatically release its contact with the mounting column 6, allowing the fixture to smoothly detach from the base and ensuring a stable and reliable deployment process.
