AI Technical Summary

Technical Problem

In the existing technology, 10kV distribution network live-line work has problems such as high safety risks for workers, high cost of robotic live-line work, and difficulty for insulated bucket trucks to reach mountainous areas, making it difficult to achieve safe and efficient live-line stripping operations.

Method used

The method employs a drone-based live-line stripping tool, which is carried by a drone and flies above the overhead conductor. Through the coordinated action of the guide plate and components, the tool clamps and fixes the conductor and performs the stripping operation, reducing the risk of manual access to live equipment and adapting to areas that cannot be reached by insulated bucket trucks.

Benefits of technology

It reduces the risk to workers from exposed live equipment without increasing costs, avoids damage to conductor cores, and enables safe and efficient live wire stripping operations in mountainous areas and other places where insulated bucket trucks cannot reach.

Abstract

This invention relates to the field of power engineering technology, specifically to a live-line stripping tool and method based on a drone. It includes two sets of guide plates arranged side-by-side, with a suspension assembly at the top. The suspension assembly includes a guide rail arranged side-by-side between the two sets of guide plates, with an electromagnetic lock on the rail. The electromagnetic lock is connected to the drone via an insulating rope. One set of guide plates has a connected blade adjusting assembly and a centering assembly on its outer side, and a rotating assembly on its inner side that drives the blade adjusting assembly and centering assembly to rotate. The centering assembly uses two sets of closely spaced centering clamps to press the conductor into the V-groove of the centering clamps, determining the conductor's axial position. The other set of guide plates has a clamping assembly on its inner side, and a traveling assembly is located between the two sets of guide plates. The clamping assembly holds and fixes the conductor using two sets of closely spaced clamping clamps. The traveling assembly uses a screw-slider structure to drive the clamping assembly, along with the main support, to move linearly along the conductor's axial direction.
