Underwater unmanned aerial vehicle

The utility model provides an underwater unmanned aerial vehicle. Comprising a fuselage, a snorkeling device arranged on the fuselage and used for driving the fuselage to float or dive, a power device arranged on the fuselage and used for driving the fuselage to move, a depth detection device used for measuring the distance between the fuselage and the sea level, and a terrain collection device used for collecting the terrain condition near the fuselage. According to the scheme, through the arrangement, the unmanned aerial vehicle is directly adopted to replace a traditional manual detection mode, the device can be safely and stably moved to a detection site, the detection efficiency is improved, and potential safety hazards are reduced. And meanwhile, the intelligent detection enables the detection and acquisition efficiency to be higher, the detection accuracy and the acquisition definition can be improved, and subsequent work is facilitated. 本实用新型提供一种水下无人机，包括机身、设置于机身上且用于驱动机身上浮或下潜的浮潜装置、设置于机身上且用于驱动机身移动的动力装置、
