AI Technical Summary

Technical Problem

Existing bird spike devices take up a lot of space during use, and the spikes can easily cause injury to people. The magnetic fixation is not reliable and there is a risk of falling, which affects the safety of high-altitude operations.

Method used

It adopts a clamping base and storage sleeve design, and uses compression springs and semi-circular drive sleeves to realize the storage and unfolding of bird spikes. Combined with the abutment limit claw and crossbeam clamping, it uses the lever principle to simplify installation, and combines pumped liquid to control the shape change of the bird spikes.

Benefits of technology

It reduces space occupation, prevents injury from sharp spikes, improves installation stability and safety, reduces the risk of falling, and simplifies the disassembly process.

Abstract

This invention provides a quick-release bird spike device for power lines, relating to the technical field of bird-proof devices for high-voltage transmission lines. It includes a clamping base, a bird spike connecting seat mounted in a lifting manner within a storage sleeve, and bird spikes mounted on the upper part of the connecting seat. Telescopic support rods are connected to both sides of the connecting seat via pivots. The telescopic support rods on the sides away from the connecting seat are pivotally connected to a semi-circular drive sleeve. An abutment limiting claw is integrally formed on the outer side of the connecting seat. In the retracted state, the bird spikes are clustered together and unfolded after installation, effectively preventing injury to people from their sharp ends. The elastic force generated by the compression spring causes the abutment limiting claw to be fixedly installed on the crossarm. The installation process utilizes the leverage effect of the semi-circular drive sleeve, making installation and disassembly relatively simple while ensuring reliable stability after installation, reducing the risk of falling, and facilitating subsequent repositioning.
