Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a power cable protection device for power transmission towers. Background Technology

[0002] In the power industry, power transmission towers serve as crucial infrastructure for power transmission, bearing the responsibility of carrying high-voltage power lines. However, with the continuous growth of electricity demand and the increasing complexity of power networks, the power cables on these towers face numerous challenges. On the one hand, severe weather conditions, such as strong winds, heavy rain, and snow, can cause varying degrees of damage to the cables, affecting their transmission efficiency and safety. On the other hand, the activities of birds and other animals can also damage the cables, even causing serious accidents such as short circuits.

[0003] Traditional methods of protecting power cables mainly rely on physical isolation and regular inspections, but these methods often have limited protective effects and high maintenance costs. Physical isolation, such as installing baffles or mesh covers, can prevent direct damage to cables from external factors to a certain extent, but it is often complex in structure, inconvenient to install, and difficult to cope with various complex environments. Regular inspections, on the other hand, require a significant investment of manpower and resources, and it is difficult to detect and address potential safety hazards in a timely manner.

[0004] Therefore, there is an urgent need in the market for an efficient, convenient, and reliable power cable protection device to address the various challenges faced by power cables on power transmission towers. This device needs to possess good stability, durability, and flexibility, providing comprehensive and multi-layered protection for power cables under various climatic conditions. Simultaneously, the device should also be easy to install and maintain to reduce maintenance costs and improve work efficiency. Utility Model Content

[0008] Optionally, the groove of the anti-wear wheel is an annular V-shaped structure, and the groove wall of the anti-wear wheel is a stepped layered structure for anti-slip and anti-detachment purposes.

[0009] Optionally, the protective cover has a tapered structure that is narrow at the top and wide at the bottom, with the edge of the protective cover covering the top of the pressure seat;

[0010] A whistle with both ends through it is fixedly installed at the edge of the protective cover along the tangential direction.

[0011] Optionally, a groove is provided laterally on the side wall of the synchronization plate that is in contact with the wire pressing seat.

[0035] Example 1: Please refer to Figures 1 to 4 :

[0036] This utility model proposes a power cable protection device for power transmission towers, comprising: a mounting plate 1, a rotating shaft 2, an anti-wear wheel 3, a protective cover 4, a synchronization plate 5, a wire pressing seat 6, and a wire pressing wheel 601; the mounting plate 1 has an L-shaped structure, and the vertical plate of the mounting plate 1 has mounting holes for installation on the power transmission tower; the rotating shaft 2 is vertically and rotatably mounted in the middle of the horizontal plate of the mounting plate 1; the anti-wear wheel 3 is rotatably mounted on the rotating shaft 2; the synchronization plate 5 is also rotatably mounted on the rotating shaft 2 between the anti-wear wheel 3 and the mounting plate 1; the wire pressing seats 6 are vertically and upwardly mounted at both ends of the synchronization plate 5; at least three wire pressing wheels 601 are rotatably mounted on the upper end of the wire pressing seat 6 at a position opposite to the anti-wear wheel 3 via wheel seats, and the power cable passes through the space between the wire pressing wheel 601 and the anti-wear wheel 3.

[0037] Among them, an arc-shaped guide groove 101 is provided on the mounting plate 1 at the position below the pressure seat 6 with the rotating shaft 2 as the center. A loading and unloading slot 102 is provided in the middle of the guide groove 101 towards the edge of the mounting plate 1. The diameter of the guide groove 101 and the loading and unloading slot 102 are the same.

[0038] Among them, the groove of the anti-wear wheel 3 is a ring-shaped V-shaped structure, and the groove wall of the anti-wear wheel 3 is a stepped layered structure, which is used for anti-slip and anti-detachment.

[0039] Among them, the protective cover 4 has a tapered structure that is narrow at the top and wide at the bottom, and the edge of the protective cover 4 covers the top of the pressure seat 6;

[0040] A whistle 401 with both ends through it is fixedly installed at the edge of the protective cover 4 along the tangential direction.

[0041] Among them, a groove 501 is horizontally opened on the side wall of the synchronous plate 5 that is connected to the pressure seat 6.

[0042] The wire clamping base 6 has an L-shaped structure. The lower end of the wire clamping base 6 is upside down on the bottom of the mounting plate 1. The wire clamping base 6 and the synchronization plate 5 are in a fitted state at the joint. The outer wall of the wire clamping base 6 at the joint is provided with a clamping groove 604 that is in contact with the groove 501. The clamping groove 604 and the groove 501 are fitted with mounting plates 603. Two mounting bolts 605 are symmetrically installed on the mounting plates 603 to fix the wire clamping base 6 and the synchronization plate 5.

[0043] A directional shaft 606 is fixed vertically downward at the middle position of the bottom plane of the wire pressing base 6, and the directional shaft 606 is slidably placed in the guide groove 101.

[0044] The working principle of this embodiment:

[0045] The device is first fixed to the power tower through the mounting holes on the mounting plate 1, providing a stable support foundation for the entire protective device. The mounting plate 1 is designed with an L-shaped structure, which not only facilitates installation but also ensures the stability of the structure.

[0046] The rotating shaft 2 is vertically mounted in the middle of the horizontal plate of the mounting plate 1, and serves as the axis of rotation for the anti-wear wheel 3 and the synchronous plate 5. As a key component, the anti-wear wheel 3 has a ring-shaped V-shaped groove with stepped groove walls. This design aims to enhance the friction between the cable and the anti-wear wheel, prevent the cable from slipping off due to wind or other external forces, and protect the cable from wear.

[0047] The synchronization plate 5 is mounted on the rotating shaft 2, located below the anti-wear wheel 3, and serves to connect and support the clamping seat 6. The clamping seat 6 is vertically mounted at both ends of the synchronization plate 5, and at least three clamping wheels 601 are rotatably mounted on the wheel seat at its upper end. These clamping wheels, together with the anti-wear wheel 3, work together to firmly clamp the power cable in the middle, ensuring the stability and safety of the cable during transmission. When the cable is subjected to external force, the clamping wheels and anti-wear wheels can rotate flexibly to absorb and disperse the external force, protecting the cable from damage.

[0048] To further enhance the protective effect, the device is also designed with a protective cover 4. The protective cover has a conical structure, with its edge covering the top of the cable clamp 6, forming an additional protective barrier. The whistle 401 on the edge of the protective cover can make a sound as the protective cover 4 rotates, achieving the effect of repelling birds and preventing birds from landing on the cable.

[0049] Structurally, the guide groove 101 and loading / unloading slot 102 on the mounting plate 1 provide space for the flexible movement of the wire clamping base 6 and the synchronization plate 5, facilitating stress relief and reducing cable friction. The wire clamping base 6 slides in the guide groove via the directional shaft 606, enabling flexible cable arrangement at different angles and directions. Simultaneously, the wire clamping base 6 and the synchronization plate 5 are tightly connected and fixed through structures such as the embedded groove 501, the clamping groove 604, and the mounting plate 603, ensuring the stability and durability of the entire protective device.

[0050] In summary, this utility model, through its ingenious design and efficient working principle, provides comprehensive and multi-layered protection for power cables on power transmission towers, ensuring the safety and stability of power transmission.
