[0002] High-voltage power lines are an important equipment for power transmission, usually used to transmit electricity from power plants to cities, industrial areas or other places that require a lot of electricity. The UAV platform is an aircraft with autonomous flight and sensing capabilities. It can carry different types of sensors and equipment to perform various tasks. Among them, the UAV platform for high-voltage power line maintenance is a UAV system designed specifically for the power industry. It integrates advanced flight control technology, sensor technology and data analysis functions to improve the efficiency and safety of high-voltage power line inspection and maintenance.

[0003] However, most drones on the market currently encounter various complex environments and weather conditions during the high-voltage power line maintenance process. When the outriggers are landing or impacted by external forces, they cannot provide sufficient buffering, which will reduce the stability of the drone platform and affect the safety and efficiency of the maintenance work. In addition, the outriggers will also directly bear the impact and vibration from the ground. In the long run, this direct impact will cause fatigue or damage to the outrigger structure, thereby shortening the service life of the drone platform. Utility Model Content
