Description

Lifting platform of aerial survey unmanned aerial vehicle Technical Field The utility model relates to the technical field of unmanned aerial vehicle landing platforms, in particular to a landing lifting platform of an aerial survey unmanned aerial vehicle. Background With the social development, the aerial unmanned aerial vehicle is widely applied to various fields such as topographic mapping, urban planning, disaster monitoring and the like by virtue of the flexible and efficient characteristics, can rapidly acquire high-resolution image data, and provides accurate information support for various industries. However, when the aerial survey unmanned aerial vehicle lands after completing the task, the safety is ensured by needing a stable landing platform, the existing aerial survey unmanned aerial vehicle is generally used outdoors, the landing is often fallen in the land with grass, as the existing landing platform cannot adjust the height, when the unmanned aerial vehicle lands, grass can be contacted with the unmanned aerial vehicle, the unmanned aerial vehicle is damaged due to the fact that parts such as a propeller and a landing gear of the unmanned aerial vehicle are possibly wound, the subsequent normal use of the unmanned aerial vehicle is influenced, the unmanned aerial vehicle is possibly caused to land unstably, accidents such as rollover occur, and even safety accidents are caused, and the flight safety of the unmanned aerial vehicle and the smooth performance of data acquisition work are seriously threatened.
