Semi-submersible unmanned vessel
By coordinating ballast tanks and pumping components, the hull's buoyancy is adjusted, and underwater propulsion and submersible propulsion are used for propulsion. This solves the problems of high resistance and instability in water navigation for semi-submersible unmanned surface vessels, achieving low energy consumption and high stability navigation.

AI Technical Summary
Technical Problem
Existing semi-submersible unmanned surface vessels (USVs) experience high drag and energy consumption due to density differences when navigating in water, and their navigation is unstable in wind and waves.
Method used
The system employs ballast tanks and pumping units to regulate the buoyancy of the hull by controlling the discharge and intake of water. It is driven by both underwater propulsion and submersible propulsion, and the hull is stabilized by separating the tanks with bulkheads, thereby reducing drag and improving stability.
Benefits of technology
In calm seas, it reduces sailing resistance and energy consumption; in rough seas, it improves sailing stability, reduces hull rolling, and enhances system reliability.

Abstract
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.
