Abstract

This invention relates to the field of unmanned aerial vehicle (UAV) technology and discloses a high-efficiency underwater UAV. The UAV is equipped with an adjustable power drive mechanism and an observation mechanism, and internally features a high-strength, lightweight internal frame and a satellite navigation system. The adjustable power drive mechanism employs a tail-mounted power unit, tail fin, and multiple side-mounted adjustable propellers in a coordinated layout. The propellers can achieve pitch, rotation, and angle adjustment, satisfying multi-attitude control requirements such as hovering, turning, climbing, and diving, with stable thrust and flexible maneuverability. It is equipped with a deep-sea pressure-resistant transparent protective cover and a sonar positioning device, combined with satellite navigation for precise positioning and navigation, providing strong protection and environmental awareness capabilities. This invention solves the problems of traditional UAVs, such as single power source, insufficient maneuverability, and limited observation capabilities. It possesses advantages such as high-efficiency navigation, precise control, strong environmental adaptability, and reliable structure, making it suitable for deep-sea exploration, engineering inspection, environmental monitoring, and other operational scenarios.
