Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically a UAV nest for power line inspection. Background Technology

[0002] High-voltage transmission lines are erected in complex geographical environments, with power poles, hardware, insulators, conductors, and ground wires directly exposed to harsh natural conditions, resulting in wear, corrosion, aging, and other damage. Once a conductor breaks or an insulator flashes, it can lead to a large-scale power outage. Therefore, regular inspections of high-voltage transmission lines are necessary. However, the complex terrain conditions make manual inspections of transmission lines very difficult. With the development of technology, drones, with their advantages of low cost, small size and weight, and remote control, are gradually being applied to the inspection of transmission lines.

[0003] Upon investigation, Chinese utility model patent CN217416135U discloses a drone cruise nest, which includes a housing and a cover plate that movably cooperates with the housing. The housing is provided with a receiving cavity, and the upper end of the housing is also provided with a hatch. The cover plate is laterally slidably disposed at the hatch for opening or closing the hatch. The housing is provided with a drive assembly, which drives the cover plate to move horizontally laterally.

[0004] Although the aforementioned patent can drive the cover plate to move smoothly by setting the drive component, reducing vibrations when opening and closing the hatch and causing the drone inside the box to shift position, it can only address the drone's position shift when opening and closing the hatch. If the drone's position shifts when it returns to base and parks, it may collide with the drone when it takes off again, causing damage. Manual intervention to adjust it would be a waste of manpower.
