[0002] Developing and utilizing wave energy is a complex issue, requiring researchers to possess knowledge in mechanics, multi-rigid-body dynamics, fluid mechanics, wave dynamics, and hydraulic transmission. Due to the dispersed nature of wave energy, high development costs, long investment cycles, and poor shock resistance, large-scale utilization and development of wave energy technology are hindered.

[0014] The gear train consists of eight components: gearbox housing I, gearbox housing end cover I, center gear I, intermediate gear IA, intermediate gear IB, intermediate gear IC, intermediate gear support frame I, and connecting shaft I. The outer side of the other end of gearbox housing I has evenly distributed bolt holes matching those of gearbox housing end cover I, and these bolts are used to securely connect the gearbox housing I to the end cover I.

The outer side of the other end of gearbox housing II has evenly distributed bolt holes matching those of gearbox housing end cover II, and these bolts are used to securely connect the gearbox housing II to the end cover II.

[0015] The other ends of the connecting shaft I and the connecting shaft II are provided with a slotted groove, which is connected to the slotted groove at one end of the flexible coupling I and the flexible connecting shaft II, respectively, and is fixed with screws at the slotted and grooved ends.

[0016] Both ends of the flexible coupling I and the flexible connecting shaft II are provided with a straight groove, and a flexible connecting piece is provided in the middle of the two connecting shafts.

[0017] The generator stator and generator rotor are each provided with a connecting shaft at one end, and each connecting shaft is provided with a slotted groove at one end that matches and connects with the slotted groove at the other end of the flexible coupling I and the flexible connecting shaft II, respectively.

[0018] The left buoy, right buoy, "raindrop-shaped" wave-absorbing float I and "raindrop-shaped" wave-absorbing float II are made of materials such as ABS and PE, and are coated with anti-corrosion materials on the outside.

[0019] The working process of the bidirectional adaptive multi-buoy roll-type wave energy generation device is as follows: The bidirectional adaptive multi-buoy roll-type wave energy generation device floats on the sea surface. The left and right buoys position the entire power generation device in a fixed position on the sea surface. The tip of the "raindrop-shaped" wave-absorbing float I faces the wave-facing or wave-backing side, while the tip of the "raindrop-shaped" wave-absorbing float II faces the wave-backing or wave-facing side. The two wave-absorbing floats face opposite directions to the wave movement. Under the action of the limiting devices on the right side of the left buoy shell and the left side of the right buoy shell, they perform unilateral free roll-type swaying motion. The waves drive the "raindrop-shaped" wave-absorbing float I to roll-type sway. At the same time, under the interaction of the limiting devices on the right side of the "raindrop-shaped" wave-absorbing float I and the left side of the "raindrop-shaped" wave-absorbing float II, the "raindrop-shaped" wave-absorbing float II is driven to generate relative motion. The "raindrop-shaped" wave-absorbing float I transmits the rotational motion to the speed increaser I through a key connection, and the rotational motion is transmitted to the flexible coupling I through the connecting shaft I. The rotational motion is then transmitted to the generator stator by the flexible coupling I. The "raindrop-shaped" wave-absorbing float II transmits the rotational motion to the speed increaser II via a key connection. The rotational motion is then transmitted to the flexible connecting shaft II via the connecting shaft II, and then to the generator rotor via the flexible connecting shaft II. Through the motion transmission of related components, the relative rotational motion of the "raindrop-shaped" wave-absorbing float I and the "raindrop-shaped" wave-absorbing float II is finally transmitted to the generator stator and the generator rotor. At the same time, relative rotational motion is also generated, which cuts magnetic field lines and generates electrical energy for power generation. Driven by continuous waves, the "raindrop-shaped" wave-absorbing float I and the "raindrop-shaped" wave-absorbing float II generate uninterrupted relative rotational motion, which in turn generates uninterrupted continuous rotational motion between the generator stator and the generator rotor, thus continuously generating electrical energy. The generated electrical energy is then stored in the storage batteries I and II through voltage stabilization and rectification processes by wires and control units.

[0020] The present invention also provides an application of a bidirectional adaptive multi-floating body roll wave energy power generation device, which combines multiple horizontal arrays, longitudinal arrays or circumferential arrays of the above-mentioned bidirectional adaptive multi-floating body roll wave energy power generation device on the sea surface to generate electricity through multiple power generation device modules.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention does not rely on intermediate conversion links such as hydraulics or pneumatics, thus reducing the loss of intermediate energy transfer. It has a simple structure, small size, and low cost, making it more suitable for power supply of marine equipment such as buoys and marine robots in the ocean.

[0023] 2. The float box and wave-absorbing float of the present invention are both hollow structures, made of materials such as ABS and PE, and coated with anti-corrosion materials on the outside. At the same time, reinforcing ribs are also set inside the cavity. The structure is lightweight, safe and durable, reducing the production and manufacturing cost of the device.

[0024] 3. The wave-absorbing float of the present invention is designed in the shape of a "raindrop", which is conducive to the tip swinging laterally around the center of the end under the action of waves. Furthermore, the relative rotational motion between the two wave-absorbing floats is significant under the limitation of the limiting device, which greatly improves the power generation efficiency of wave energy conversion.

[0025] 4. By selecting a suitable size for the wave-absorbing float, the present invention can enable the wave-absorbing float to resonate with the waves at the same frequency, thereby further enhancing the wave energy capture efficiency and significantly improving the wave energy conversion efficiency.

[0026] 5. The floating boxes of the present invention all have built-in counterweights, and the center of gravity is concentrated near the bottom, which improves the stability of the power generation device operation;

[0027] 6. The multiple floating bodies such as the buoy and the wave-absorbing float of the present invention cooperate with each other, and adaptively adjust the roll angle between the wave-absorbing floats according to the wave conditions. It can absorb wave energy in multiple directions, which greatly improves the power generation efficiency of the wave energy power generation device.

[0028] 7. The wave energy power generation device of the present invention can be arrayed in multiple groups on the sea surface for grid-connected power generation, and can also be applied in the fields of power supply for ships at sea and civilian offshore power generation, thus expanding the application scenarios of wave energy power generation device.

Under the action of the limiting device on the left side of the side and right float hull 201, it makes a unilateral free lateral swaying motion; the wave-driven "raindrop-shaped" wave-absorbing float I5 sways laterally, and at the same time, under the interaction of the limiting devices on the right side of "raindrop-shaped" wave-absorbing float I5 and the left side of "raindrop-shaped" wave-absorbing float II6, it drives "raindrop-shaped" wave-absorbing float II6 to generate relative motion. "Raindrop-shaped" wave-absorbing float I5 transmits the rotational motion to speed increaser I3 through key connection, and the rotational motion is transmitted to flexible coupling I9 by connecting shaft I7, and then the rotational motion is transmitted to flexible coupling I9 by flexible coupling I9. The motion is transmitted to the generator stator 1101 of the generator 11. The "raindrop-shaped" wave-absorbing float II6 transmits the rotational motion to the speed increaser II4 via a key connection. The rotational motion is then transmitted to the flexible connecting shaft II10 via the connecting shaft II8, and then to the generator rotor 1102 of the generator 11 via the flexible connecting shaft II10. Through the motion transmission of related components, the relative rotational motion of the "raindrop-shaped" wave-absorbing float I5 and the "raindrop-shaped" wave-absorbing float II6 is finally transmitted to the generator stator 1101 and the generator rotor 11. 02. Simultaneously, relative rotational motion is generated, which cuts magnetic field lines, generates electrical energy, and generates electricity. Driven by continuous waves, the "raindrop-shaped" wave-absorbing float I5 and the "raindrop-shaped" wave-absorbing float II6 generate uninterrupted relative rotational motion, which in turn generates uninterrupted relative rotational motion between the generator stator 1101 and the generator rotor 1102, thereby continuously generating electrical energy. The generated electrical energy is then stored in batteries I12 and II13 through voltage stabilization and rectification processes by wires and control units.

The left and right buoys position the entire generator in a fixed location on the sea surface. The tip of the "raindrop-shaped" wave-absorbing float I faces the wave-facing or wave-backing side, while the tip of the "raindrop-shaped" wave-absorbing float II faces the wave-backing or wave-facing side. The two floats face opposite directions towards the wave movement and, under the action of limiting devices on the right side of the left buoy and the left side of the right buoy, perform a unilateral free roll-and-swing motion. Waves drive the roll-and-swing motion of the "raindrop-shaped" wave-absorbing float I. Simultaneously, the interaction of the limiting devices on the right side of the "raindrop-shaped" wave-absorbing float I and the left side of the "raindrop-shaped" wave-absorbing float II causes relative motion in the "raindrop-shaped" wave-absorbing float II. The rotational motion of the "raindrop-shaped" wave-absorbing float I is transmitted to the speed increaser I via a key connection, then to the flexible coupling I via the connecting shaft I, and finally to the flexible coupling I. The generator stator is connected to the "raindrop-shaped" wave-absorbing float II via a key connection, which transmits the rotational motion to the speed increaser II. The connecting shaft II then transmits the rotational motion to the flexible connecting shaft II, which in turn transmits it to the generator rotor. Through the movement of related components, the relative rotational motion of the "raindrop-shaped" wave-absorbing float I and the "raindrop-shaped" wave-absorbing float II is ultimately transmitted to the generator stator and the generator rotor. Simultaneously, relative rotational motion is generated, which cuts magnetic field lines and generates electrical energy. Driven by continuous waves, the "raindrop-shaped" wave-absorbing float I and the "raindrop-shaped" wave-absorbing float II generate uninterrupted relative rotational motion, which in turn generates uninterrupted continuous rotational motion between the generator stator and the generator rotor, thus continuously generating electrical energy. The generated electrical energy is then stored in batteries I and II after being regulated and rectified by wires and the control unit.
