Large unmanned aerial vehicle suitable for taking off and landing on different terrains

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a large unmanned aerial vehicle suitable for taking off and landing in different terrains, which comprises an unmanned aerial vehicle body, a telescopic structure is mounted on the unmanned aerial vehicle body, a supporting structure is mounted on the telescopic structure, a protective structure is mounted on the unmanned aerial vehicle body, and a connecting structure is mounted on the protective structure. A furling structure is mounted on the unmanned aerial vehicle body, and a fixing structure is mounted on the furling structure; the telescopic structure is installed on the unmanned aerial vehicle body, the unmanned aerial vehicle body can be adjusted up and down through the telescopic structure when water exists on the ground, stable landing of the unmanned aerial vehicle is facilitated, the unmanned aerial vehicle body can be prevented from sinking when the unmanned aerial vehicle body lands on a muddy road surface through the supporting structure, and when the water level is too high and the road surface cannot be seen clearly, the unmanned aerial vehicle body is prevented from directly sinking into a muddy road surface hidden in water.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a large-scale unmanned aerial vehicle adapted to take off and land on different terrains. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. With the maturity of UAV technology, it is possible to use UAV to complete some difficult, dangerous, toxic and harmful tasks that are difficult for humans to complete. , UAVs can be used for plant protection, surveying and mapping, photography, high-voltage cables, and agricultural and forestry inspections. UAVs also have a broad application space in logistics and other fields, but in some disaster-stricken areas, due to road damage and other factors, it is not convenient and timely To send materials to the disaster area, large drones can be used for material delivery at this time. [0003] However, after the disaster in some disaster a...

Problems solved by technology

[0003] However, after the disaster in some disaster areas, the road surface may be flooded or muddy. At this time, if the UAV needs to land, it may be flooded or the landing gear and the muddy road surface may sink due to the small stress area. It will cause the UAV to fail to put into work in time, and when the UAV is transporting materials, if it encounters windy weather, some hanging materials will shake too much, which will easily cause the UAV to fall Damage, when the drone is used to deliver materials to the disaster area, the drone stops working to pick up the goods, and then takes off, which affects the delivery efficiency of the drone, and the drone does not stop working to pick up the goods, no one The wings of the aircraft are easy to cause injury to the picker
