Abstract

The invention provides an unmanned aerial vehicle (UAV) capable of running underwater or overhead. The UAV comprises a UAV body, wherein the UAV body is provided with at least one UAV arm; the end of each UAV arm is respectively provided with a driving part; rotors are mounted on the top end of the driving parts; marine propellers are mounted under the bottom end of the driving parts; and the rotors are connected with the marine propellers by one-way bearings or one-way clutches. When the UAV flies overhead, a motor drives the rotors to rotate to realize the normal flight of the UAV overhead, and the attitude adjustment is realized through the control of the rotors. In this case, the effect of the marine propellers is not good in the sky, and the marine propellers does not affect the flight of the UAV. When the UAV runs underwater, the motor drives the marine propellers to work, and in this case, the rotors does not provide the efficiency required for underwater movement and does not work. By increasing the rotating speed of the marine propellers, the UAV moves downwards to be underwater, and then the underwater running of the UAV is realized through the attitude control of the UAV. The UAV capable of running underwater or overhead can realize aerial operation and underwater operation and expand the working field of the UAV.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a water-air amphibious unmanned aerial vehicle. Background technique [0002] With the continuous development of micro drone technology, we have put forward higher requirements for the technology and functions of drones. Common drones fly and operate in the air. Based on the expansion of the application field of drones, the research and development of amphibious drones can further promote the promotion and use of micro drones. Considering the difference in fluid conditions and densities in the air and water, the current quadrotor unmanned rotor cannot propel the drone well underwater due to the limitation of volume and material, and its efficiency is low. The marine propeller is small in size and high in hardness. It can be selected at high speed underwater to provide greater propulsion and propel the drone forward. [0003] After searching, the Chinese...
