This application relates to the technical field of unmanned surface vessels (USVs), and in particular to a semi-submersible USV, comprising a
hull,
ballast assembly, and control
assembly. The
hull includes a base and a
canopy, with the
canopy fixedly connected to the top of the base. An
underwater propulsion unit is mounted at the
stern of the base, and a submersible propulsion unit is mounted at the
stern of the
canopy. The
ballast assembly includes a
ballast tank and a pumping unit. The
ballast tank is mounted on the base, and one end of the pumping unit communicates with the
ballast tank, while the other end communicates with the bottom of the base. The control assembly includes a battery, a
control unit, and a
communication unit. The battery and
control unit are mounted inside the base, and the
communication unit is fixedly connected to the top of the canopy. The battery and
control unit are electrically connected, and the control unit and
communication unit are also electrically connected. In calm sea conditions, the
hull floats, and the submersible propulsion unit drives the hull, significantly reducing drag during movement. This application effectively reduces
energy consumption during navigation.
