Specifically, the two sets of paired hydrofoils have two pairs of four differential hydrofoils 1 in total, all of which are connected to the fixed shaft 2 fixed on the support, one pair is located at the bow, and the other pair is located at the stern.

Specifically, the control mechanism includes a wave vertical velocity sensor 3, a hydrofoil rotation angle sensor 4, a generator 6, a gear box 5, a microprocessor and a control module 7 arranged on the hull 9, and a load controller 8, The wave vertical flow velocity sensor 3 is arranged at both ends of each fixed shaft 2 for obtaining the wave vertical flow velocity; the hydrofoil rotation angle sensor 4 is arranged between the two ends of each fixed shaft 2 and the hydrofoil, Used to obtain the rotation angle of each differential hydrofoil 1; the gearbox 5 of the generator 6 is built in each differential hydrofoil 1, the input end of the gearbox 5 is connected to the fixed shaft 2, and the output end is connected to Generator 6, the output end of described generator 6 is connected to the lithium battery, and in order to adapt to the reliability of long-term operation on the water, the described generator 6 adopts a waterproof generator; flow rate sensor, hydrofoil rotation angle sensor and load controller, the load controller is connected with the microprocessor and control module through a circuit, and is used to control the electric load of each generator, thereby controlling each differential hydrofoil 1 swing amplitude and swing speed, so that each differential hydrofoil 1 performs differential rotation around the fixed shaft 2, so as to obtain the maximum thrust to realize the maximum speed or obtain different thrusts to realize heading control.

In addition, when the hull stops sailing, the load controller 8 controls the power load of each generator 6, thereby controlling the swing amplitude and swing speed of each differential hydrofoil 1, so that each generator 6 can obtain the optimal electric energy output .

The differential hydrofoil wave propeller provided by the above embodiments utilizes the energy of wave motion, and each differential hydrofoil 1 rotates around the fixed shaft 2 while generating heave motion along with the waves. When the differential hydrofoil wave propeller rises upwards, the follow side of the differential hydrofoil 1 turns downward, and when the differential hydrofoil wave propeller slides to the trough, the follow side of the differential hydrofoil 1 turns upward. The rotation of the differential hydrofoil 1 and the direction of the heave motion form a preset included angle, which is called the angle of attack in the field of airfoil, so that the differential hydrofoil 1 generates forward propulsion power. That is to say, the differential hydrofoil 1 can be regarded as a source of power for the boat to move forward.

During the sailing process of the hull 9, the control mechanism combines the hydrofoil rotation position provided by the hydrofoil rotation angle sensor and the wave vertical flow velocity provided by the wave vertical flow velocity sensor to construct different electric loads to adjust the movement speed and swing amplitude of each differential hydrofoil 1 , used to absorb the rotational impact energy of the hydrofoil, and control the differential movement of the hydrofoil according to the optimized propulsion model, in order to obtain the maximum thrust and improve the sailing speed and efficiency.

When the hull 9 stops sailing, each differential hydrofoil 1 moves to drive the gearbox 5, and the gearbox 5 then drives the generator 6 to generate electricity to charge the lithium battery as a (electricity) load to absorb impact energy. Practice has shown that when each differential hydrofoil 1 has different swing amplitudes and swing speeds, the power generation efficiency of the generator 6 driven by it will be different. In order to obtain the optimal power generation efficiency, the load controller 8 controls The power load of each generator 6 controls the swing amplitude and swing speed of each differential hydrofoil 1 , so that each generator 6 can obtain the optimal electric energy output, and improve the power generation efficiency of each generator 6 .
