Description

Technical Field

[0001] This utility model relates to the field of bird deterrence devices for cable towers, and more particularly to a bird deterrence device for cable towers. Background Technology

[0002] With the rapid development of my country's power grid, high-voltage transmission lines have become a crucial infrastructure for the national economy. Cable towers, as the supporting structures for overhead transmission lines, are exposed to the natural environment for extended periods, facing various risks of biological attack, with bird activity posing a particularly prominent safety hazard. Statistics show that in 2022, over 3,700 line tripping incidents were caused by bird activity in the national power grid, accounting for 18.6% of all transmission faults that year, resulting in direct economic losses exceeding 780 million yuan. Birds' nesting, defecating, and pecking activities on cable towers can not only cause short-circuit accidents, but the organic matter they carry can also accelerate the corrosion process of metal components, seriously affecting the safety and reliability of the power grid operation.

[0003] Traditional bird control techniques primarily employ either physical barriers or chemical repellents. The most common method is the bird spike device, which uses densely packed metal needles to form a physical barrier. However, in practical applications, it has been found that bird spikes only effectively protect the top area of ​​the tower and are prone to structural deformation and failure due to strong winds. While chemical repellents offer significant initial effects, they pose a risk of environmental residue. Utility Model Content
