Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a unmanned aerial vehicle with a magnetic probe telescopic fixing system. Background Art

[0002] With the rapid development of drone technology, drones are increasingly being used in various fields. Especially in the fields of geological exploration and mineral resource survey, drones equipped with various sensors for aerial detection have become the mainstream. Among them, magnetic detection technology has important application value in these fields due to its high sensitivity and high resolution.

[0003] In the related art, magnetic detection drones generally use fixed magnetic probes and hanging magnetic probes. The fixed magnetic probe is to fix the magnetic probe on the bottom of the drone or other parts. This solution is simple and easy to implement, but the magnetic probe is easily interfered by the drone's own magnetic field, resulting in reduced detection accuracy. The hanging magnetic probe is to suspend the magnetic probe at a certain distance below the drone through a rope. This method makes the magnetic probe have a certain distance from the drone body, which can reduce the drone's own magnetic field interference. However, due to the existence of the rope, especially in high wind conditions, it is easy to affect the flight stability of the drone. Summary of the invention
