Description

Technical Field

[0001] This utility model belongs to the field of protection device technology, and specifically relates to an extended protection device for surveying drones. Background Technology

[0002] A surveying drone is a type of unmanned aerial vehicle (UAV) system specifically designed for the surveying and mapping field. It combines UAV technology, remote sensing technology, and geographic information system (GIS) technology to acquire geospatial information quickly, efficiently, and accurately.

[0003] Currently, protective devices are installed on the wings of surveying drones to protect them. However, traditional protective devices have certain problems in use. For example, traditional protective devices are generally wing guards, which are designed with a ring around the surface of the wing to cover the wing and prevent it from colliding with foreign objects. Although they can achieve the protection effect, the size of the guard is fixed after production. Since the wings of surveying drones are of different sizes, the fixed size cannot be adjusted, so it cannot be used for wings of different sizes. Utility Model Content
