Abstract

The application discloses a cable mounting and dismounting clamp matched with an external damage prevention warning lamp, relates to the technical field of high-voltage transmission line auxiliary equipment, and aims to solve the technical problems of the traditional warning lamp clamp, such as easy discharge ablation of the conductor, narrow cable adaptation range, easy loosening of clamping, and power-off operation during mounting and dismounting. The clamp is integrally formed with a metal equipotential conductive structure, thereby eliminating the potential difference between the clamp and the conductor and the micro-gap discharge hidden danger. The buckle type quick-change small clamp is used to realize the full adaptation of the clamp, the 12mm-35mm clamp and the cable.

The overall protection grade of the clamp reaches IP66 of the clamp, and the clamp has the characteristics of operation safety, reliable clamping, strong universality and efficient mounting and dismounting, and is suitable for the quick mounting and dismounting of the external damage prevention warning device of the high-voltage overhead transmission line.

Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for high-voltage transmission lines, specifically to a metal clamping device for an externally damaged warning light that is compatible with multiple cable specifications and can be quickly installed and removed by drones. Background Technology

[0002] In my country's high-voltage overhead transmission line network, a large number of lines traverse urban suburbs, industrial parks, construction sites, and major traffic arteries. The risk of these lines being damaged by construction machinery such as excavators, cranes, and concrete pump trucks, as well as oversized vehicles and floating debris, is continuously increasing. External damage has become one of the main causes of unplanned outages, line breaks, and tower collapses. To effectively reduce the incidence of external damage accidents, power operation and maintenance units generally install external damage warning lights at critical crossing points of transmission line conductors and ground wires, in densely populated construction areas, and at accident-prone locations. These lights utilize active nighttime illumination to provide a direct warning to nearby personnel and equipment, thereby ensuring the safe and stable operation of transmission lines.

[0003] Currently, anti-damage warning lights generally use a gull-type insulated clamping device to secure the wire: the clamp body is a metal part, with insulating pads attached to the inner wall, and a single torsion spring provides clamping force, holding the wire in line contact. This structure has significant drawbacks in long-term engineering applications: 1. The clamp and the conductor are isolated by an insulation layer to form a non-equipotential structure. Under the long-term effects of line vibration, wind swaying, diurnal temperature variation deformation, and ultraviolet aging, the insulation layer is prone to wear, cracking, peeling, and warping. This leads to the formation of tiny air gaps between the clamp and the conductor, causing local electric field distortion and intermittent air discharge. Long-term discharge will directly burn the surface of the conductor, and in severe cases, it will cause the conductor strands to break and the strength to decrease, threatening the safety of the line itself. 2. Traditional clamps have a fixed opening size and can only match wires with a single outer diameter. They cannot cover the mainstream steel-cored aluminum stranded wires in the 12mm-35mm clamp range. Multiple clamps of various specifications need to be equipped on site according to the wire type, resulting in a large number of spare parts, high management costs, and complicated replacement operations. 3. Relying solely on a single torsion spring to provide clamping force, with a tangential line contact, the clamping pressure is unevenly distributed. Under harsh conditions such as strong winds, line vibration, and icing, the clamps are prone to loosening, slippage, and deflection, leading to the warning lights shifting, falling off, or becoming ineffective, thus losing their warning and protective function. 4. Traditional warning light clamps do not have a quick-release mechanism after installation. If maintenance, replacement or relocation is required, the line must be de-energized, or the disassembly must be carried out by professionals using insulated operating rods and equipotential working methods. The operation process is complicated, the operation risk is high, and the power outage affects a wide range, which seriously reduces the reliability of power grid supply and operation and maintenance efficiency.

[0004] The above problems are interconnected and are all caused by the insulation isolation structure, fixed size design, single-power clamping method and non-linkage assembly and disassembly structure of traditional clamping devices. Existing technologies cannot solve these problems simultaneously in one device. Therefore, there is an urgent need for a new type of clamping device that is structurally integrated, rationally designed, safe to operate, and easy to assemble and disassemble. Summary of the Invention

[0005] The purpose of this invention is to provide a cable installation and removal clamp for a warning light designed to prevent external damage. This clamp has the advantages of equipotential anti-discharge, wide compatibility with a wide range of cables, stable clamping, and quick installation and removal of drones without power outages. It solves the problems of traditional clamping devices, such as easy discharge, loose clamping, poor compatibility, and high risk of installation and removal operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable installation and removal clamp for an anti-damage warning light, comprising a metal clamping assembly, a conductive assembly, a clamping power assembly, an installation and removal linkage assembly, and a silicone protective assembly. The metal clamping assembly includes a first clamp, a second clamp, and a quick-release clamp fixing seat. The first clamp and the quick-release clamp fixing seat are integrally formed from metal material, and the second clamp is rotatably connected to the first clamp via a hinge. The clamping power assembly includes a hinge torsion spring and a tension spring. The hinge torsion spring is sleeved on the hinge pivot, and the tension spring connects the first clamp and the quick-release clamp fixing seat. The installation and removal linkage assembly includes a top plate, an elastic reset pin, and a removal rod. The top plate, the elastic reset pin, and the removal rod are interconnected and can form a triggering engagement with a top rod mounted on a UAV to realize the installation and removal of the device. The silicone protective assembly includes a high-pressure weather-resistant silicone sleeve and a waterproof pad, with a protection level of IP.

[0007] The invention is further configured such that the second clip and the quick-release clip fixing base are connected by a snap-on quick-release connection. The second clip is standardly equipped with a 12~25mm cable and can be replaced with a larger specification second clip that is compatible with 25~35mm cables. The second clip has a circular arc-shaped structure.

[0008] The above technical solution allows for quick replacement of clip two without tools, is compatible with mainstream steel-cored aluminum stranded wires from 12mm to 35mm, and features a rounded, encircling design to ensure full contact with the conductor, improving adaptability and versatility.

[0009] The present invention is further configured such that the inner side of the second clip is provided with a high-pressure weather-resistant silicone layer, and the surface of the silicone layer is provided with anti-slip texture.

[0010] The above technical solution avoids mechanical wear on the wires through flexible contact, and the anti-slip texture increases static friction, thereby improving clamping stability.

[0011] The present invention is further configured such that the hinge torsion spring provides the initial clamping force and the tension spring provides the secondary locking force, forming a dual-power graded clamping structure.

[0012] The above technical solution abandons the single spring reset and uses graded clamping to ensure that the cable is tight without damage, resists vibration and wind, and does not loosen during long-term operation.

[0013] The present invention is further configured such that the top plate is pressed to trigger the locking pin to disengage, thereby achieving installation, and the disassembly rod is pressed to trigger the locking pin to disengage, thereby achieving disassembly.

[0014] The above technical solution, linked with the drone's top rod, enables power-free and contactless assembly and disassembly, allowing for single-person, single-machine operation, reducing operational risks and improving efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up an integral metal clamping component and an equipotential conductive structure, has the advantages of stable conductivity and no risk of discharge, eliminates potential difference and micro gap, prevents electric field distortion and air discharge, and protects the wire from damage. 2. This invention has the advantage of wide applicability by setting a snap-on replaceable clip, which is compatible with mainstream cables from 12mm to 35mm, without the need to replace the entire clamp, and has strong versatility. 3. This invention features a dual-power, graded clamping mechanism with a hinge torsion spring and a tension spring, providing a firm grip, multi-point circumferential contact, resistance to line vibration and wind interference, and no displacement during long-term operation. 4. This invention, through the linkage structure of the top plate, locking shaft, and disassembly rod, has the advantages of rapid assembly and disassembly of drones, eliminating the need for power outages, enabling contactless operation, and requiring no equipotential operation, thus ensuring safety and efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] Please see Figure 1-3 A cable installation and removal clamp for an external damage warning light includes a metal clamping assembly, a conductive assembly, a clamping power assembly, an installation and removal linkage assembly, and a silicone protective assembly. The metal clamping assembly includes a first clamp 14, a second clamp 15, and a quick-release clamp fixing seat 9. The first clamp 14 and the quick-release clamp fixing seat 9 are integrally formed from metal material, and the second clamp 15 is rotatably connected to the first clamp 14 via a hinge. The clamping power assembly includes a hinge torsion spring 16 and a tension spring 11. The hinge torsion spring 16 is sleeved on the hinge pivot, and the tension spring 11 connects the first clamp 14 and the quick-release clamp fixing seat 9. The installation and removal linkage assembly includes a top plate 13, an elastic reset pin 12, and a removal rod 10. The top plate 13, the elastic reset pin 12, and the removal rod 10 are interconnected and can form a triggering engagement with a top rod mounted on a drone to realize the installation and removal of the device. The silicone protective assembly includes a high-pressure weather-resistant silicone sleeve and a waterproof pad 7, with a protection level of IP66.

[0020] Please see Figure 1 Clip 2 15 and clip quick-release mounting base 9 adopt a snap-on quick-release connection. The standard configuration includes clip 2 15, which is compatible with 12~25mm cables. A larger size clip 2 15, which is compatible with 25~35mm cables, can be replaced. Clip 2 15 has a rounded, wrap-around structure, which can be quickly replaced without tools. It is compatible with mainstream steel core aluminum stranded wires from 12mm to 35mm. The rounded, wrap-around design ensures full contact with the wire, improving adaptability and versatility.

[0021] Please see Figure 1 The inner side of clip 15 is provided with a high-voltage weather-resistant silicone layer. The surface of the silicone layer is provided with anti-slip texture. The flexible contact avoids mechanical wear of the wires, and the anti-slip texture increases static friction and improves clamping stability.

[0022] Please see Figure 1 The hinge torsion spring 16 provides the initial clamping force, and the tension spring 11 provides the secondary locking force, forming a dual-power graded clamping structure. This eliminates the need for a single spring reset, and the graded clamping ensures that the cable is tight without damage, resists vibration and wind, and does not loosen during long-term operation.

[0023] Please see Figure 1-3 When the top plate 13 is pressed, the locking shaft 12 is released to achieve installation. When the disassembly rod 10 is pressed, the locking shaft 12 is released to achieve disassembly. It is linked with the top rod of the drone to achieve power-free and contactless installation and disassembly. It can be operated by a single person and a single machine, reducing operation risks and improving efficiency.

[0024] Brief description of the usage process: During installation, replace the second clip 15 with the appropriate one according to the outer diameter of the cable. The drone carrying the device flies to the installation position, pushes the cable with the top rod and presses down the top plate 13. The pressure on the top plate 13 triggers the release of the locking shaft 12. The hinge torsion spring 16 drives the second clip 15 to initially clamp the cable. After the top plate 13 is completely released, the tension spring 11 tightens to achieve secondary locking, completing the installation. During disassembly, the drone's top rod is aligned with the disassembly rod 10 and pushed upwards. The disassembly rod 10 drives the locking shaft 12 to release, and the tension spring 11 loosens to release the secondary locking. Continue pushing to release the second clip 15. The drone drives the device to descend to complete the disassembly.
