Description
Technical Field
[0001] The invention relates to a broken strand repair execution device for a power line, belonging to the technical field of power line safety devices. Background Art
[0002] As a vital component of the national economy, the power industry has a significant impact on social production and people's lives. High-voltage transmission lines are a crucial component and foundation for the operation of power systems. Due to the large cross-sectional area of conductors, long spans, and long installation distances, as well as their frequent construction in open areas such as mountain ridges and plains, conductors and overhead ground wires are constantly exposed to harsh environmental conditions such as strong winds, icing, lightning strikes, and corrosion. Broken strands and wires often occur. Under the influence of natural wind, broken aluminum wires can vibrate and scatter, short-circuiting with nearby conductors and posing a threat to the safe operation of transmission lines. Every year, incidents such as interphase discharges, short-circuit fires, and power outages caused by broken strands occur frequently, causing immeasurable economic losses to people's production and daily lives. To this end, power operations and maintenance departments across the country invest significant manpower, material, and financial resources annually to inspect broken strands and repair and reinforce transmission lines to maintain their normal operation.
[0003] Traditional transmission line broken strand repair is mainly done manually. First, the inspection personnel observe and determine the damage, broken strand condition and location of the conductor. Then the operators reach the vicinity of the broken strand by manual climbing or taking an insulated boom truck or helicopter, and use crimping tools to crimp or wrap pre-twisted wire to repair the broken strand.
[0004] With the advancement of science and technology, some semi-automatic, mobile, online strand repair robots have been developed and put into practical use. These robots can significantly improve operational efficiency and reduce the risks associated with manual operation. However, the strand repair equipment they carry is complex, bulky, and difficult to carry. They often require manual assistance to climb up and down the line, have limited endurance, and cannot be used in some complex environments.
[0005] Therefore, there is an urgent need for a broken strand repair execution device for power lines, which can be used in conjunction with a multi-rotor aircraft to efficiently bandage the broken strands of the power lines to prevent the occurrence of power accidents. It has the characteristics of light weight, small size, easy to carry, simple operation and high safety. Summary of the Invention
