Docking device of autonomous underwater vehicle and submarine observation network

The invention discloses a docking device of an autonomous underwater vehicle and a submarine observation network. The docking device comprises two parts of an autonomous underwater vehicle and a docking station main body. The autonomous underwater vehicle comprises a first hoop, a buoyancy ring and a first electric energy communication cavity and a conical protective sleeve, wherein the first hoop, the buoyancy ring and the first electric energy communication cavity are fixed on the autonomous underwater vehicle main body; the conical protective sleeve is sleeved on the autonomous underwater vehicle main body; and the docking station main body comprises a supporting rod, a horn entry guide, a cylindrical entry guide, a second electric energy communication cavity, a control cavity and a mechanism, wherein the supporting rod is installed on a universal joint, a coaxial line of the entry guide and the cylindrical entry guide is fixed on the supporting rod, and the mechanism is used for clamping the autonomous underwater vehicle main body tightly. When the docking device is adopted, the autonomous underwater vehicle drives into the horn entry guide and stops in the docking station main body reliably through the guidance of the horn entry guide and the cylindrical entry guide and the limit of the conical protective sleeve, and charging of the autonomous underwater vehicle as well as transmission of the electric energy and a signal between the autonomous underwater vehicle and the submarine observation network are realized. The invention has the advantages of simple structure and convenience for control.
