[0069] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0070] The invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0071] Example 1

[0072] An internal oscillation wave power generation device based on a single-oscillator cross-axis mechanism. Figure 1 A schematic diagram of the overall structure of an embodiment of the present invention is shown, as follows. Figure 1 As shown, it includes:

[0073] Enclosed floating body (1), guiding unit (2), transmission unit (3) and power generation unit (4);

[0074] The guiding unit (2), the transmission unit (3) and the power generation unit (4) are located in the internal cavity of the enclosed float (1).

[0075] The enclosed float (1) has a cavity inside. The specific structure of the enclosed float (1) is not limited here. It can be a rectangular structure or a frustum structure. Optionally, in this embodiment, the enclosed float (1) is a fully enclosed structure and a cylindrical structure. When the power generation device in this embodiment is placed in the ocean to generate electricity, the lower end of the cylindrical structure is close to the seabed and the upper end of the cylindrical structure is far away from the seabed. The cylindrical structure has good structural stability and can remain stable in a complex marine environment. The fully enclosed design allows the float to better resist the erosion of seawater and protect the internal components from damage.

[0076] The guide unit (2) is connected to the enclosed float (1), and the power generation unit (4) is connected to the guide unit (2) through the transmission unit (3).

[0077] Under the influence of wave energy, the guiding unit (2) drives the power generation unit (4) and the transmission unit (3) to move along the guiding direction of the guiding unit (2); the transmission unit (3) moves in the guiding direction defined by the guiding unit (2) to drive the power generation unit to generate electricity; wherein, the guiding direction of the guiding unit (2) includes the axial direction and the radial direction of the enclosed float. For example, when using the enclosed float (1) with a cylindrical structure in the embodiment of the present invention, the guiding direction of the guiding unit (2) is the axial direction and the radial direction of the cylinder.

[0078] The guide unit (2) is connected to the enclosed float (1), ensuring that the guide unit can be stably fixed on the float and move with the movement of the float. The power generation unit (4) is connected to the guide unit (2) through the transmission unit (3), forming a linked system. When waves act on the enclosed float (1), the float will move with the rise and fall of the waves. This movement is transmitted to the guide unit (2), and the transmission unit (3) moves along the guide direction defined by the guide unit under the drive of the guide unit (2). This movement is converted into the power input of the power generation unit (4), thereby driving the power generation unit to generate electricity. Since the guide direction of the guide unit (2) includes the axial and radial directions of the enclosed float, it can effectively adapt to and convert wave energy from different directions.

[0079] The specific structure of the guide unit (2) is not limited here. In this embodiment, the guide unit (2) can be designed as a combination of a series of bearings and rails, so that the transmission unit (3) and the power generation unit (4) can slide freely on the rails, while the bearings ensure the smoothness of the movement. The guide unit (2) can also use hydraulic or pneumatic cylinders as the guide and support structure, and control and stabilize the movement of the transmission unit (3) and the power generation unit (4) by the pressure of the fluid. The guide unit (2) can also use flexible materials (such as high-strength ropes or chains) combined with specially designed guide pulleys or sliders to adapt to the multidimensional movement of the transmission unit (3) and the power generation unit (4) under the action of waves. In this embodiment, the guide unit (2) includes a guide rail (2-1) and a slider (2-2) that cooperates with the guide rail. The guide rail (2-1) is connected to the enclosed float (1), and the slider (2-2) is connected to the transmission unit (3). Under the action of wave energy, the slider (2-2) drives the transmission unit (3) and the power generation unit (4) to move along the guide direction through the guide rail (2-1). The specific structure of the guide rail (2-1) is not limited here. It can be a single guide rail structure or a double guide rail structure. When the guide rail (2-1) is a double guide rail structure, the slider (2-2) slides with the double guide rail. The guide unit (2) includes an axial guide unit and a radial guide unit. The length direction of the guide rail (2-1) of the axial guide unit is along the axial direction of the closed float (1), and the length direction of the guide rail (2-1) of the radial guide unit is along the radial direction of the closed float (1). The guide rails in the two directions together form a rectangular frame. The transmission unit and the power generation unit are both set inside the rectangular frame.

[0080] Figure 2 This is a schematic diagram of a transmission unit and a power generation unit according to an embodiment of the present invention; Figure 3 This is another schematic diagram of the transmission unit and power generation unit according to one embodiment of the present invention, as shown below. Figure 2 and Figure 3 As shown,

[0081] The specific content of the transmission unit (3) is not limited here. The transmission unit (3) includes a first transmission component (3-1), a second transmission component (3-2), and a third transmission component (3-3). One end of the first transmission component (3-1) is connected to the slider (2-2) in the guide unit (2), and the other end is connected to the power generation unit (4). Here, it can be directly connected to the power generation unit (4) or indirectly connected. The function of the first transmission component (3-1) is to transmit the wave energy to the power generation unit (4), so that the power generation unit (4) moves along the first transmission component (3-1) in the guide direction. The first transmission component (3-1) drives the power generation unit (4) to move in the guide direction by compression and expansion. In this embodiment, the other end of the first transmission component (3-1) is indirectly connected to the power generation unit (4). Through the housing (5), the power generation unit (4) is connected to the housing (5), such as Figure 1 As shown, at least a portion of the power generation unit (4) is disposed outside the housing (5), and another portion is disposed inside the housing (5). The power generation unit (4) is fixed to the housing (5). The two ends of the first transmission member (3-1) abut against the housing (5) and the guide unit (2) respectively; the first transmission member (3-1) drives the housing (5) to move while simultaneously driving the power generation unit (4) to move.

[0082] The two ends of the second transmission component (3-2) abut against the opposite sides of the guide unit (2); the guide unit (2) is a rectangular frame structure, and the two ends of the second transmission component (3-2) abut against the opposite sides of the rectangular frame; when the power generation unit (4) is fixed on the housing (5), the second transmission component (3-2) passes through the housing (5) and connects with the opposite sides of the rectangular frame of the guide unit (2).

[0083] The third transmission component (3-3) meshes with the second transmission component (3-2); when the second transmission component (3-2) penetrates the housing (5), the third transmission component (3-3) is located inside the housing (5), and the third transmission component (3-3) meshes with the second transmission component (3-2) inside the housing (5), and is connected to the part of the power generation unit (4) inside the housing (5). When the first transmission component (3-1) is compressed and extended along the guide direction, it drives the housing (5) to move along the direction of compression and extension of the first transmission component (3-1), and the housing (5) drives the power generation unit (4) fixedly connected to it to move in the same direction. When the power generation unit (4) moves along the direction of compression and extension of the first transmission component (3-1), it drives the third transmission component (3-3) connected to it to rotate along the length direction of the second transmission component (3-2), and the third transmission component (3-3) drives the power generation unit (4) to generate electricity through rotation.

[0084] Furthermore, in this embodiment, the first transmission component (3-1) includes an elastic component (3-1-1), the second transmission component (3-2) includes a rack (3-2-1), and the third transmission component (3-3) includes a gear (3-3-1); one end of the elastic component (3-1-1) is connected to the slider (2-2) of the guide unit (2), and the other end abuts against the housing (5); the specific content of the elastic component (3-1-1) is not limited here, and it can be a spring, a soft rubber column, etc.

[0085] The elastic component (3-1-1) drives the power generation unit (4) to move along the guide direction; the rack (3-2-1) abuts against the opposite surface of the guide unit (2), and the length direction of the rack (3-2-1) is the same as the guide direction; the gear (3-3-1) includes a gear shaft, one end of which is connected to the power generation unit; when the gear (3-3-1) rotates, it drives the power generation unit (4) to rotate and generate electricity through the gear shaft. The other end of the gear shaft is connected to the housing (5), ensuring the stable operation of the gear. The elastic component (3-1-1) is a flexible connection, and the gear and rack are rigid connections. The flexible connection has high flexibility and adaptability, and can better adapt to changes in length, angle and shape of the structure. As a rigid connection, the gear and rack have high structural stability. Through hard contact direct meshing, various positioning errors caused by intermediate links can be eliminated, so the positioning accuracy is high. The synergistic effect of the flexible connection and the rigid connection can efficiently convert wave energy into electrical energy, improving the energy conversion efficiency.

[0086] The specific content of the power generation unit (4) is not limited here. In this embodiment, the power generation unit (4) includes an axial generator (4-1) and a radial generator (4-2); the transmission unit (3) includes an axial transmission unit and a radial transmission unit; the axial transmission unit moves along the guiding direction defined by the axial guide unit; the radial transmission unit moves along the guiding direction defined by the radial guide unit. The axial transmission unit includes a first transmission component (3-1), a second transmission component (3-2), and a third transmission component (3-3). The radial transmission unit includes a first transmission component (3-1), a second transmission component (3-2), and a third transmission component (3-3).

[0087] An axial generator (4-1) is connected to an axial drive unit; a radial generator (4-2) is connected to a radial drive unit. The compression and expansion direction of the first drive component of the axial drive unit is the axial direction of the enclosed float; the compression and expansion direction of the first drive component of the radial drive unit is the radial direction of the enclosed float. By separately setting up axial generators (4-1) and radial generators (4-2), wave energy from different directions can be captured and converted more effectively. Axial generator (4-1) focuses on converting energy in the axial direction of the enclosed float, while radial generator (4-2) converts energy in the radial direction; this improves the overall energy conversion efficiency.

[0088] Furthermore, in this embodiment, the transmission unit (3) also includes a connecting rod (3-4), the two ends of which abut against the opposite side of the guide unit (2);

[0089] The connecting rod (3-4) and the rack (3-2) are in the same length direction. The connecting rod (3-4) and the rack (3-2) are arranged parallel to each other. The connecting rod (3-4) passes through the housing (5) and abuts against the opposite side of the guide unit (2). One connecting rod (3-4) is arranged radially and one axially. The connecting rod (3-4) and the rack (3-2) in the same direction are symmetrically arranged with respect to the central axis of the housing (5). The elastic member (3-1) includes a connecting rod elastic member sleeved on the connecting rod. The two ends of the connecting rod elastic member abut against the guide unit (2) and the power generation unit (4) respectively. The elastic member (3-1) also includes a rack elastic member sleeved on the rack. The two ends of the rack elastic member abut against the guide unit (2) and the power generation unit (4) respectively. The compression and expansion directions of the rack elastic member and the connecting rod elastic member are the same as the guide direction. Figure 1 As shown, there are four elastic members (3-1-1) on the axial direction, respectively sleeved on the connecting rod (3-4) and the rack (3-2), and four elastic members (3-1-1) on the radial direction, respectively sleeved on the connecting rod (3-4) and the rack (3-2), making the transmission system more stable.
