[0002] Overhead ground wire generally refers to one or more conductors on the top layer of the power transmission and distribution line, also known as lightning arrester, which is a conductor directly connected to the earth. Due to the shielding of the conductor by the overhead ground wire and the coupling effect between the conductor and the overhead ground wire, the chance of lightning directly striking the conductor can be reduced. When lightning strikes the tower, part of the lightning current can be diverted through the overhead ground wire, thereby reducing the potential at the top of the tower and improving the lightning resistance level. Common overhead ground wires are mostly galvanized steel stranded wire, aluminum-clad steel stranded wire, optical fiber composite ground wire, etc.

[0003] Because the overhead ground wire is exposed to wind and sun for a long time, fatigue cracks will occur when the stress or vibration reaches a certain level, causing the strands of the stranded wire to break, become scattered, or become disconnected over time. When the wire is subjected to a local large current, such as a lightning strike, it is also prone to melting, resulting in broken or scattered strands.

Such operation is relatively simple, so the technical solution of this embodiment effectively solves the problem of low overhead ground wire repair efficiency in the related art.

This structural design not only ensures the structural strength of the device, but also enables the device to be more stable when clamping the overhead ground wire, reduces the safety hazards during operation, and is suitable for power line maintenance work in various complex environments. In actual use, this structural design can withstand the test of various extreme weather conditions, ensure the stability and safety of the equipment in complex terrain and harsh environments, and provide a solid guarantee for the maintenance of power lines.

[0042] Specifically, a bearing seat is provided on the limit block 16, and the lead screw 22 is connected to the bearing seat, so that the position of the lead screw 22 is more stable.

The device can also integrate more functions, such as real-time monitoring, data collection and analysis, to further enhance its role in power system maintenance.

[0047] Specifically, the use process of the technical solution of this embodiment is as follows:

[0050] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0051] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.
