Further, the wave energy conversion kinetic energy unit includes:

Side panels, airfoils and stepper motors;

The side plate is vertically connected with the screw rod, the front end adopts a semicircle, the tail end adopts a T-shape, and a notch is opened at the bottom, and the notch is used to mount the wing piece, and the rear end of the wing piece is installed with a Described stepper motor. Further, the side panels may be single-piece or double-piece. Further, a hole is provided at the top of the notch for reinforcing the airfoil.

Specifically, as shown in FIG. 3 to FIG. 4 , the wave energy conversion kinetic energy unit includes a side plate 3 , a fixed screw 1 , and an airfoil 2 . The thin plate is used, the head of the side plate 3 adopts a semicircular design, and the tail adopts a "T"-shaped design; there is a notch under the side plate 3 to reduce lateral resistance and provide mounting space. Semi-circular design, the front adopts arc design, the arc radius is the same as the head of side plate 3; there is a hole above the notch of side plate 3, which is used to install and fix the wing. The side plate 3 is provided with a single piece or a double piece (single piece in the figure), and the side plate is connected and fixed symmetrically by four fixing screws.

The airfoils described in this embodiment are provided with 10 pieces in total, all of which are outer airfoils 2; 3 vertical connections. As shown in Figure 2, the structure of the wing set includes a connecting round shaft 4, a torsion spring, and a bearing (not shown in the figure). The circular shaft 4 and the two outer wing pieces 2 are respectively fixed on the two ends of the side plate 3 by means of the connecting circular shaft 4 through fastening screws.

In the whole process, there is no external energy supply, and the mechanical structure is completely relied on to convert wave energy into forward thrust.

As shown in Figure 5, further, it also includes: a frictional nanogenerator connected to the storage battery; the frictional nanogenerator is a frictional nanolayer arranged outside the hull shell, Layers are fixed with screws.

Specifically, add a layer of shell 15 on the hull 14, keep the gap that exists freely with the hull 14 under the condition of no pressure, increase the friction nano layer inside the double shell of the hull, and the shell of the ship is designed As the insulating layer of the generator, the two polymer materials have a large difference in the ability to capture electrons. The inner shell of the ship is fixed by the fixed screw 1 at the bottom. Through the non-directional impact of the waves, the double shell will generate friction due to the impact, so that it will be in close contact with the friction nano-layer on the inner surface of the shell and undergo charge transfer, so that the two The inner surface of the polymer sheet is electrically opposite to the triboelectric charge through periodic contact-separation due to the triboelectric effect. When the deformation is released due to the undirectional motion of the wave, the two oppositely charged surfaces will automatically separate, and the opposite frictional charge will generate an electric field between the two surfaces, thereby forming an electric field between the two electrodes. Potential difference, in order to shield this potential difference, electrons will be driven to flow from one electrode to the other through an external circuit. The current generated during this process will continue until the potentials of the two electrodes are equalized again. Subsequently, when the outer shell is compressed again towards the tribo-nanolayer on the outside of the hull, the potential difference induced by the triboelectric charge starts to decrease to zero, and the transferred charge will flow back through the external circuit, generating another current pulse in the opposite direction. When the waves sustain this periodic mechanical deformation, an alternating current signal will continue to be generated, inducing a periodic change in potential difference. There is nanomaterial support between the two layers of thin plates. If it is fixed with the hull with connecting rods, and a layer of cover is buckled on the top and the hull, the shell can be fixed. Wave undulations cause the heave motion of the ship on the water surface, and the heave motion causes the lifting motion of the underwater tractor through the connecting rod, and the rotating joint hydrofoil converts the lifting motion into the forward motion of the underwater tractor, and the forward motion is passed through The connecting rod causes the forward movement of the water rocking boat. Therefore, on the undulating sea surface, the underwater tractor is always under the front and bottom of the swaying ship on the water surface.

When the waves are raised, the ship swings vertically upward under the action of buoyancy, and due to the forward and downward pulling force of the connecting rod, a forward speed is generated, that is, when the wave rises, the ship must move forward. sports. When the waves are raised, the underwater tractor is subjected to the upward and backward pulling force of the connecting rod, and the hydrofoil produces a downward and forward lift force. At this time, it is difficult to determine whether the underwater tractor is moving forward. However, at this time, there is a critical angle for judging the forward and backward movement of the underwater tractor. When the angle formed by the cable and the vertical line is less than the critical angle, the underwater tractor moves forward. When it is greater than the critical angle, the underwater tractor moves forward. Backward movement (when the waves are raised, the ship must move forward when the water surface is swaying, so the included angle gradually decreases, so that the included angle is smaller than the critical angle, and the underwater tractor starts to move forward). When the wave sinks, the rocking ship undergoes a vertical downward heaving motion under its own gravity. At this time, whether the rocking ship is moving forward is still undetermined. However, at this time there is a critical distance (the length of the connecting rod) for judging whether the rocking boat moves forward, that is, when the connecting rod is tight, the rocking boat must move forward; when the connecting rod is loose, the rocking boat keeps Stay in place. During this process, the surface swaying ship heaves downward under the action of waves, and its speed conforms to the sinusoidal law, that is, it has a high downward speed at the equilibrium position. For the underwater tractor, it slides downward under its own gravity , has a constant taxiing speed, so the most likely relaxation process occurs in the middle of the wave sag, when the water surface is swaying and the ship is stationary and the underwater tractor is sliding forward. In the front period of wave sag, when the water surface shakes the ship, the underwater tractor also moves forward; during the rear end period, when the water surface shakes the ship moves forward, and the underwater tractor moves forward.

The utility model combines mechanical power transmission technology, photovoltaic effect solar panel, wave energy conversion kinetic energy device, rotor blower wind propulsion system, wireless transmission and maritime early warning technology. The photovoltaic effect adopts the direct conversion method of light and electricity, which uses the photoelectric effect to directly convert solar radiation energy into electrical energy; the utilization of wind energy, the aerodynamic principle used when using the rotary sail is the Magnus effect , the rotating cylinder moves forward and will be subjected to a lateral force perpendicular to the direction of motion; the wave energy utilization is mainly composed of a frame, and a floating board that can float up and down is installed in the frame, and the characteristic is that the floating board is equipped with a crank And the connecting rod, the crank is arranged on the frame through the bearing seat, the connecting rod is movably connected with the floating plate, and the crank is also externally connected with a power output. And add a nano-friction film layer on the outer surface of the hull, so that when the hull impacts with seawater, the inner and outer layers of the hull will undergo relative displacement, causing friction between the inner and outer layers to generate electrical energy, which will be stored in the battery to achieve the purpose of making full use of wave energy; information transmission , Relying on the existing ship-to-shore wireless transmission technology, a camera is installed on the ship, and a wireless communication device is equipped to obtain its position, weather conditions, wind pressure, wind speed, wind direction, etc., so as to realize the early warning function.
