Profile buoys have become a global marine real-time observation system and are widely applied to marine hydrological and meteorological investigation, but the existing profile buoys work in a way that reciprocating vertical motion is measured between the surface of seawater and deep seawater, horizontal motion cannot be performed, and more complex and accurate observation tasks cannot be performed. Meanwhile, the buoy has overlarge drift distance and deviates from an expected observation sea area due to sea waves, ocean currents and trim in the self sinking and floating process, so that the positioning accuracy is low. If the propeller propulsion system is directly added, the vertical posture of the propeller propulsion system also generates larger resistance, and the propeller propulsion system is not beneficial to horizontal driving due to the limitation of electric energy of the buoy.
Therefore, the existing section buoy can not well meet the fine observation of the medium and small-scale upper ocean, and an attitude adjusting and horizontal propelling system for the section buoy is urgently needed to break through the technical bottleneck of high space-time resolution observation of the medium and small-scale ocean observation.
