Remote sensing surveying and mapping unmanned aerial vehicle with high safety

Abstract

The invention discloses a remote sensing surveying and mapping unmanned aerial vehicle with high safety, which comprises a vehicle body, wings are arranged on the two sides of the vehicle body, a front propeller is arranged in the front of the vehicle body, and a tail vane is arranged at the tail of the vehicle body; wherein a fixed rod parallel to the aircraft body is symmetrically fixed in each of the two wings, vertical propellers are rotatably arranged at the two ends of each fixed rod, and each vertical propeller can be driven by a vertical motor fixed in the corresponding fixed rod to rotate; a plurality of arc-shaped protection blocking pieces are distributed at the bottom of the vertical propeller in the circumferential direction of the vertical propeller, the protection blocking pieces are connected with the fixing rod through protection rods, and the protection rods can adjust the distance between the protection blocking pieces and the center of the vertical propeller; compared with the prior art, the unmanned aerial vehicle can be in a vertical lifting mode and a fixed wing mode and is good in maneuverability, high in surveying and mapping efficiency and large in activity range. And the protection blocking pieces can be opened and closed, a protection net is formed between the protection blocking pieces and the protection ropes, safety is high when the device is close to the ground, and air resistance is small when the unmanned aerial vehicle is high.

Problems solved by technology

[0003] According to the flight characteristics, the existing remote sensing mapping UAVs can be divided into two types: fixed-wing UAVs and unmanned helicopters. Fixed-wing UAVs can take off, land and fly through the power system and the sliding of the wings. , strong wind resistance, fast speed, high surveying and mapping efficiency, and long battery life, but the take-off and landing of fixed-wing UAVs requires a relatively open space and taxiing on the runway, and the use scenarios are limited; the technical advantages of unmanned helicopters It is able to take off and land at a fixed point, does not have high requirements on the conditions of the takeoff and landing site, has good maneuverability, has better obstacle avoidance ability, and can be suspended at a fixed point, but its flight speed is slow, the effective range of surveying and mapping is small, and the battery life is short. It is mainly used in investigation of emergencies

[0004] Existing UAVs capable of vertical take-off and landing are prone to hitting obstacles such as personnel, buildings, and branches in low altitudes, and are prone to safety accidents during take-off and landing. Protecting the propeller can improve its safety, but when there are no obstacles when flying at high altitude and high speed, the protective cover becomes a burden instead, increasing air resistance and limiting the flight speed, and the protective cover is also easy to disturb the airflow, which is harmful to drones. operations have an impact on
