Description

Technical Field

[0001] The present invention relates to the technical field of power transmission operation and maintenance technology, and in particular to a remote-controlled electric cylinder clamping multi-dimensional steering grounding device. Background Art

[0002] Ground rods are important power maintenance equipment and are indispensable in the operation and maintenance of high-voltage transmission lines. Their role is to ensure the personal and operational safety of workers. With the rapid development of the national economy, in order to meet the demand for electricity and the rapid development of power grid construction, there are more and more ultra-high voltage transmission lines such as 220kV and 500kV. Ultra-high voltage lines are exposed to the external environment for a long time and are easily affected by external forces or the natural environment and fail. They need to be regularly inspected and maintained, such as cleaning, zeroing, and replacing insulator strings, as well as replacing ground wires, spacers, and shock-absorbing hammers. In order to ensure the safety of maintenance personnel, when overhead transmission lines are shut down for maintenance, ground wires must be hung at both ends of the maintenance area to prevent personal injury caused by sudden power or induced voltage in the maintenance area.

[0003] The currently used 220kV and above high-voltage overhead line grounding wires cannot adapt well to the maintenance work of high-voltage overhead lines, mainly manifested in: 1. The connection of the terminal clamp is unstable; 2. The traditional grounding wire clamp cannot adjust the angle between the wire clamp and the operating rod. The wire clamp hook and the operating rod are in a straight line, which makes it impossible for maintenance personnel standing on the cross arm of the tension tower to hang the grounding wire clamp to the outside of the porcelain bottle string; 3. When using the grounding rod, there is often a certain angle between the staff and the conductor, which easily leads to poor contact between the clamp and the conductor, causing the clip to slip or a gap between the clamp and the conductor, causing the risk of discharge, thereby causing the risk of burning the clamp and the conductor, and even causing personal electric shock casualties.

[0004] Due to the existence of the above problems, the workload of installing and removing the grounding wire increases, which wastes the time of power outage maintenance and the physical strength of the operators. This not only reduces the economic benefits of the enterprise, but also increases the possibility of sudden power supply (reverse power supply, induced power supply, wrong power supply, etc.) due to the long time of installing the grounding wire, further increasing the danger of the operation. Therefore, it is urgent to solve this problem. Therefore, it is urgent to develop a new type of multi-dimensional steering portable grounding wire. Summary of the invention
