Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with an external buffering and shock-absorbing support base. Background Art

[0002] Drone firefighting is widely used in various fields. Many firefighting agencies have successfully used drones to conduct fire scene reconnaissance and monitoring, drop rescue supplies and high-altitude firefighting. For example: in order to make better use of water sources at the fire-fighting location and improve the efficiency of water source utilization, drones are used to connect water pipes and cooperate with fire trucks to extinguish fires. The fire-fighting location is accurately controlled by drones.

[0003] In the existing technology, when a firefighting drone lands on the ground after extinguishing a fire, due to its own gravity and other equipment, its inertia is very large and has a certain impact force on the ground, which can easily cause damage to the drone body, making it unusable for a second time. In more serious cases, the drone will be directly scrapped, which not only wastes a lot of maintenance time, but also increases investment costs. Utility Model Content
