Wire bird nesting-preventing mechanism based on small angle rotating structure

Abstract

The invention belongs to the technical field of high voltage safety and especially relates to a wire bird nesting-preventing mechanism based on a small angle rotating structure. The wire bird nesting-preventing mechanism comprises wires, a driving lever, a cardan joint, rotating discs, a flexible cord, a beam, a volute spiral spring, a first guide rod circular plate and a rotating ring, wherein the wires on the two sides of the beam are connected with the flexible cord through connectors; internal thread holes are formed at the center of the rotating discs; external threads of an external thread rod are matched with internal threads of the internal thread holes through the threads; when the wires are blown by wind, the rotating discs are driven to rotate around the external thread rod by the wires and the rotating discs on the two sides of the beam are approached toward the middle part, so that the wires are straightened and the wires are prevented from being touched in a rotating process; when the wind is stopped or fluctuated, the volute spiral spring can return the rotating discs. The wire bird nesting-preventing mechanism has a simple structure; the circuit fault caused by bird nesting or other foreign matters close to a wire tower can be avoided by rotating the rotating discs for small angles following the wind; the wire bird nesting-preventing mechanism has better practical effect.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electric safety, and in particular relates to a wire bird-proof nesting mechanism based on a small-angle rotating structure. Background technique [0002] At present, the wires installed on the high-voltage power towers generally cannot be rotated, and the wires are fixed on the power towers. On the one hand, bird’s nests or other foreign objects are prone to appear near the power towers, and it is difficult to clean them; if they are not cleaned in time, circuit failures will occur Power outage; On the other hand, if the wind speed is very large, blowing the wires, because the wires are fixedly installed on the power tower, the wind is too strong and the wires are likely to break. [0003] The present invention designs a wire anti-bird nesting mechanism based on a small-angle rotation structure to solve the above problems. Contents of the invention [0004] In order to solve the above-men...

Problems solved by technology

[0002] At present, the wires installed on the high-voltage power towers generally cannot be rotated, and the wires are fixed on the power towers. On the one hand, bird’s nests or other foreign objects are easy to appear near the power towers, and it is difficult to clean them; if they are not cleaned in time, it will cause circuit failure and cause Power outage; on the other hand, if the wind speed is very strong and the wires are blown, because the wires are fixedly installed on the wire tower, the wires are likely to break due to excessive wind
