Description

technical field [0001] The invention mainly relates to the technical field of unmanned aerial vehicles, in particular to an emergency safety landing device for a bridge detection unmanned aerial vehicle. Background technique [0002] With the continuous maturity and development of UAV technology, its application fields are becoming more and more extensive. In the field of bridge inspection, special drones have also appeared to take pictures of the bottom surface, cylinder, beams, stay cables and other parts of the bridge for experts to inspect, saving time and effort and making the inspection more comprehensive. However, most of the bridges are set on the river. Once the drone collides with the bridge, it needs to make an emergency landing if it fails, and it will fall into the water. In the existing technology, structures such as airbags and parachutes have appeared for the emergency and safe landing of UAVs, but these structures can only ensure that UAVs land on the groun...

Problems solved by technology

However, most of the bridges are set on the river. Once the drone collides with the bridge, it needs to make an emergency landing if it fails, and it will fall into the water.

In the prior art, structures such as airbags and parachute aids have appeared for the emergency and safe landing of drones, but these structures can only ensure that the drone lands on the ground smoothly. When the drone is in the process of bridge inspection During an emergency landing, it will still fall into the water and be damaged
