[0002] Floating breakwaters are devices used to defend against wave intrusion and form a sheltered waterway. Floating breakwaters not only ensure the safety of the sheltered waterway, allowing personnel or equipment to operate safely and stably within it, but they are also increasingly chosen in practice due to their strong adaptability and ease of construction. Wave energy, as a clean, renewable, and high-density energy source, has enormous potential for development and utilization. If floating breakwaters can be combined with wave energy power generation technology, not only can the efficient utilization of wave energy be achieved, but the functionality of floating breakwaters can also be further expanded.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0052] The accompanying drawings show schematic diagrams of layer structures according to embodiments of the present invention. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations.

[0053] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0054] In the description of this utility model, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] Combination Figures 1 to 4 The first aspect of this utility model provides a portable breakwater based on wave energy power generation, hereinafter referred to as the breakwater. The breakwater includes an upper floating body 1, a lower floating body 2, a first power generation component 3, a second power generation component 4, and an energy storage component. The first power generation component 3 and the second power generation component 4 are disposed within the upper floating body 1, and the energy storage component is disposed within the lower floating body 2. The first power generation component 3 and the second power generation component 4 are electrically connected to the energy storage component. The first power generation component 3 includes a movable baffle 31, a magnet 32, and a coil 33. A first groove 1a is formed on the side of the upper floating body 1. The movable baffle 31 and the first... The bottom of the groove 1a is elastically connected, the magnet 32 ​​is fixedly connected to the movable baffle 31, the coil 33 is fixedly connected to the bottom of the first groove 1a, and the movable baffle 31 can drive the magnet 32 ​​to move in the axial direction of the coil 33; the second power generation component 4 includes a generator, a gear pair 41, a connecting rod structure 42, a horizontal plate 43 and a base 44. The generator is fixedly connected to the upper floating body 1, the gear pair 41 is connected to the rotating shaft of the generator, the gear pair 41 is connected to the horizontal plate 43 through the connecting rod structure 42, the horizontal plate 43 is movably connected to the base 44, and the base 44 is fixedly connected to the bottom of the upper floating body 1.

[0056] Specifically, the upper floating body 1 and the lower floating body 2 form the main body of the breakwater. The upper floating body 1 carries the power generation components, and the lower floating body 2 houses the energy storage components, realizing functional zoning and facilitating equipment installation and maintenance. The movable baffle 31 of the first power generation component 3 reciprocates along the first groove 1a under the action of waves, driving the magnet 32 ​​to cut the magnetic field lines of the coil 33 to generate electricity, directly generating electricity using the reciprocating motion of the waves. The horizontal plate 43 of the second power generation component 4 converts the motion of the wave-driven horizontal plate 43 relative to the upper floating body 1 into the rotation of the generator shaft through the linkage structure 42 and the gear pair 41. The energy storage components store electrical energy, realizing the collection, storage and distribution of energy, and improving energy utilization efficiency. The specific shapes of the upper floating body 1 and the lower floating body 2 are not limited here. Preferably, the upper floating body 1 has a planar structure facing the waves and an arc-shaped structure facing away from the waves, which is conducive to the absorption of wave energy. The lower floating body 2 is set as a frustum structure with an increased bottom diameter, which improves the overall stability of the breakwater.

[0057] With this configuration, a first power generation component 3 and a second power generation component 4 are integrated into the breakwater. The energy of the wave impact is converted into electrical energy by the first power generation component 3, and the energy of the portable breakwater floating in the waves is converted into electrical energy by the second power generation component 4. This allows the breakwater to absorb wave energy more comprehensively and improves the energy absorption and utilization rate. By setting the breakwater as the upper floating body 1 of the power generation area and the lower floating body 2 of the energy storage area, the overall stability of the breakwater is improved. At the same time, it facilitates the transportation and installation of the breakwater and ensures that the breakwater can operate stably in complex environments.

[0058] It should be noted that the specific arrangement of the first power generation component 3 and the second power generation component 4 on the upper floating body 1 is not limited here. Preferably, the first power generation component 3 is located on the front of the upper floating body 1 where it is impacted by wave energy, and the second power generation component 4 is located on the inner side of the upper floating body 1. This allows the movable baffle 31 of the first power generation component 3 to move within the first groove 1a under the impact of wave energy, and the horizontal plate 43 of the second power generation component 4 to have relative movement with the upper floating body 1. The specific direction of movement of the horizontal plate 43 is also not limited, as long as there is relative movement between the horizontal plate 43 and the upper floating body 1, and the movement of the horizontal plate 43 relative to the upper floating body 1 can be converted into the rotation of the gear pair 41.

[0059] like Figure 7 As shown, in a preferred embodiment, the base 44 has a spherical joint 441 at its top, and the base 44 is connected to the horizontal plate 43 via a ball hinge. Specifically, the ball hinge allows the horizontal plate 43 to rotate in three dimensions (front and back, up and down, left and right), fully adapting to the complex motion of waves and ensuring that the horizontal plate 43 always follows the waves, maximizing energy absorption.

[0060] With this configuration, the ball joint allows for multi-directional rotation. Regardless of the wave direction, the horizontal plate 43 can rotate effectively, improving energy absorption efficiency. It can convert the three-dimensional motion of the horizontal plate 43 into gear rotation. The spherical contact reduces wear and stress concentration, enhances durability in marine environments, reduces the risk of equipment damage, and extends service life.

[0061] It should be noted that the specific manner in which the horizontal plate 43 drives the gear pair 41 to rotate during the rotation is not limited here, but is combined with Figure 4 The "arbitrary direction" described here does not refer to rotation around point O of the ball joint. In an optional scenario, the gear pair 41 needs to be fitted onto the generator shaft. During the power generation process of the second power generation component 4, the relative position of the gear pair 41 and the generator shaft is fixed, and they rotate together. There is a limit in the axial direction of the shaft. In some cases, this limit restricts the rotation of the horizontal plate 43 in a certain direction. In this case, the rotation direction of the horizontal plate 43 is limited to the direction that can drive the gear pair 41 to rotate. When the rotation of the horizontal plate 43 and the limited movement direction of the gear pair 41 (i.e., the movement relative to the generator shaft) interfere, the horizontal plate 43 is limited by the connecting rod structure 42, so that the horizontal plate 43 will not rotate in this direction.

[0062] In a preferred embodiment, the gear pair 41 includes a first bevel gear 411 and a second bevel gear 412. The first bevel gear 411 is vertically arranged and sleeved on the generator shaft, while the second bevel gear 412 is horizontally arranged and meshes with the first bevel gear 411. Specifically, in the initial state, the horizontal plate 43 is arranged horizontally along the X-axis, and the generator is located behind the first bevel gear 411 in the Y-axis direction, with its shaft arranged horizontally along the Y-axis. During the movement of the horizontal plate 43, the first bevel gear 411 can be directly driven to rotate through the connecting rod structure 42, and the first bevel gear 411 drives the generator shaft to rotate and generate electricity. When the horizontal plate 43 cannot directly drive the first bevel gear 411 to rotate in some directions, it can drive the second bevel gear 412 to rotate, and the second bevel gear 412 meshes with the first bevel gear 411, thereby realizing the rotation of the first bevel gear 411.

[0063] With this configuration, the orthogonally arranged first bevel gear 411 and second bevel gear 412 directly match the spatial layout, eliminating the need for additional transmission components and improving efficiency. The multi-directional rotation of the horizontal plate 43 is converted into the rotation of the generator shaft driven by the first bevel gear 411, enhancing adaptability to different wave directions, such as utilizing both vertical and horizontal waves, and improving wave energy conversion efficiency.

[0064] Combination Figures 4 to 7In a preferred embodiment, the linkage structure 42 includes a first vertical rod 421, a first connecting rod 422, a second vertical rod 423, and a second connecting rod 424. The first vertical rod 421 is connected to the horizontal plate 43, and the first vertical rod 421 is rotatably connected to the first connecting rod 422. The first connecting rod 422 is rotatably connected to the first bevel gear 411. When the horizontal plate 43 rotates relative to the base 44 in a first direction, the first vertical rod 421 and the first connecting rod 422 drive the first bevel gear 411 to rotate. The second vertical rod 423 is connected to the horizontal plate 43, and the second vertical rod 423 is rotatably connected to the second connecting rod 424. The second connecting rod 424 is rotatably connected to the second bevel gear 412. When the horizontal plate 43 rotates relative to the base 44 in a second direction, the second vertical rod 423 and the second connecting rod 424 drive the second bevel gear 412 to rotate.

[0065] Specifically, when the horizontal plate 43 rotates in the first direction, it rotates around the Y-axis in the vertical plane (the plane where X and Z are located). At this time, the second vertical rod 423 remains stationary, and the first vertical rod 421 moves with the horizontal plate 43 in the vertical direction. The first connecting rod 422 is rotatably connected to the first vertical rod 421, and the first connecting rod 422 rotates around the axis of the first bevel gear 411, thereby driving the first bevel gear 411 to rotate. When the horizontal plate 43 rotates in the second direction, it rotates around the Z-axis in the horizontal plane (the plane where X and Y are located). At this time, the first vertical rod 421 remains stationary, and the second vertical rod 423 moves with the horizontal plate 43 in the horizontal plane. The second connecting rod 424 is rotatably connected to the second vertical rod 423, and the second connecting rod 424 rotates around the axis of the second bevel gear 412, thereby driving the second bevel gear 412 to rotate.

[0066] With this setup, each set of links can independently transmit power in a single direction, ensuring effective motion transmission and avoiding interference; independent transmission reduces energy loss, adapts to dynamic waves, enhances stability, and improves power generation efficiency and equipment reliability.

[0067] It should be noted that the first and second directions described here are determined based on the specific installation position of the generator within the upper floating body 1. The specific arrangement of the gear pair 41, connecting rod structure 42, and cross plate 43 can be adaptively adjusted according to the generator's specific position, ensuring that the cross plate 43 can drive the generator shaft to rotate when rotating in the aforementioned two directions. Furthermore, the first and second directions do not mean that the cross plate 43 can only achieve the aforementioned transmission effect by rotating in a single first or second direction. The cross plate 43 can be used in these two directions or in more complex motion scenarios, where the gear pair 41 is constrained by the generator shaft, and the connecting rod structure 42 restricts the rotation of the cross plate 43 in some directions, for example... Figure 4In the middle, the horizontal plate 43 is restricted from rotating around the X-axis in the YZ plane. Under this condition, as long as the horizontal plate 43 can rotate, there are two directions of rotation, namely the first direction and the second direction. This can drive the first bevel gear 411 to rotate in the first direction and drive the second bevel gear 412 to rotate in the second direction. The two are superimposed to further improve the energy conversion efficiency.

[0068] In a preferred embodiment, the second power generation component 4 further includes a first ratchet structure 45 and a second ratchet structure 46. A first connecting rod 422 is connected to a first bevel gear 411 via the first ratchet structure 45, and a second connecting rod 424 is connected to a second bevel gear 412 via the second ratchet structure 46. Specifically, the first ratchet structure 45 allows only the first bevel gear 411 to rotate in one direction, and the second ratchet structure 46 allows only the second bevel gear 412 to rotate in one direction, thereby achieving unidirectional rotation of the generator shaft. This configuration filters the effective direction, protects the generator, improves energy utilization, avoids ineffective losses, and the ratchet mechanism is mature, low-cost, suitable for long-term use in marine environments, and reduces maintenance costs.

[0069] It should be noted that the specific shapes of the first link 422 and the second link 424 are not limited here, such as... Figure 5 and Figure 6 In an optional configuration, both the first link 422 and the second link 424 adopt a Y-shaped structure. When the first link 422 and the second link 424 rotate around their respective axes, they drive the first bevel gear 411 and the second bevel gear 412 to rotate in one direction via a ratchet structure. The specific direction of the unidirectional rotation of the first bevel gear 411 and the second bevel gear 412 is not limited here, as long as the rotation direction of the generator shaft is consistent during the power generation process and the rotation directions of the first bevel gear 411 and the second bevel gear 412 do not conflict. The specific number of each component in the link structure 42 is also not limited. Optionally, two of each of the following components are provided: the first vertical rod 421, the first link 422, the second vertical rod 423, and the second link 424. The first vertical rod 421 and the first link 422 correspond one-to-one, and the second vertical rod 423 and the second link 424 correspond one-to-one. At this time, the first ratchet structure 45 includes two ratchets, and each first link 422 drives one ratchet. The second ratchet structure 46 includes two ratchets, and each second link 424 drives one ratchet.

[0070] It should be noted that the specific manner in which the second vertical rod 423 remains stationary when the horizontal plate 43 rotates in the first direction is not limited, nor is the specific manner in which the first vertical rod 421 remains stationary when the horizontal plate 43 rotates in the second direction. In a preferred embodiment, a second groove 43a is formed on the horizontal plate 43, and the first vertical rod 421 is movably connected to the second groove 43a. When the horizontal plate 43 rotates in the second direction, the first vertical rod 421 slides against the second groove 43a. A buffer portion 431 is provided on the surface of the horizontal plate 43, and the second vertical rod 423 is connected to the horizontal plate 43 through the buffer portion 431. When the horizontal plate 43 rotates in the first direction, the second vertical rod 423 slides against the buffer portion 431.

[0071] Specifically, when the horizontal plate 43 rotates in the first direction, a sliding space is formed in the vertical direction within the buffer part 431, and the top position of the second vertical rod 423 is fixed. When the buffer part 431 moves with the horizontal plate 43 in the vertical direction, the bottom of the second vertical rod 423 slides with the sliding space within the buffer part 431, thereby fixing the position of the second vertical rod 423 when the horizontal plate 43 rotates in the first direction. When the horizontal plate 43 rotates in the second direction, a horizontal sliding space is formed within the second groove 43a. At this time, the horizontal plate 43 rotates around the Z-axis, the top position of the first vertical rod 421 is fixed, and the bottom of the first vertical rod 421 slides within the sliding space in the second groove 43a, thereby fixing the position of the first vertical rod 421. At this time, the second groove 43a is an arc structure shaped around point O.

[0072] With this configuration, when the horizontal plate 43 rotates in the first and second directions, it drives the first bevel gear 411 and the second bevel gear 412 to rotate respectively, avoiding the restriction of the horizontal plate 43's rotation in the first and second directions caused by the connecting rod structure 42, thereby ensuring the continuity of the horizontal plate 43's rotation and improving power generation efficiency.

[0073] Combination Figure 1 In a preferred embodiment, the top cover 11 of the floating body 1 is provided with a third power generation component 5, which is electrically connected to the energy storage component. The third power generation component 5 includes a photovoltaic panel 51 and a support rod 52, and the photovoltaic panel 51 is fixedly connected to the top cover 11 through the support rod 52. Specifically, the photovoltaic panel 51 is installed on the top cover 11 of the floating body 1 to convert light energy into electrical energy and transmit it to the energy storage component.

[0074] This setup combines photovoltaics and wave energy to enhance the diversity of energy utilization and ensure a continuous and sufficient energy supply. The photovoltaic system on the top cover (11) requires no additional land, enabling a portable design, expanding energy acquisition pathways, and improving the utilization rate of the breakwater structure.

[0075] In a preferred embodiment, the top of the floating body 1 is provided with an arc-shaped breakwater wall 12, which is located above the first power generation component 3. Specifically, the arc-shaped wall guides the water flow to concentrate and impact the movable baffle 31, thereby improving the electromagnetic power generation efficiency. At the same time, in environments with large waves, the breakwater wall 12 guides the wave flow, disperses some of the wave impact, enhances the overall stability of the breakwater, and extends the service life of the equipment.

[0076] In a preferred embodiment, the movable baffle 31 is provided with a limiting ring 311, the center of the magnet 32 ​​coincides with the center of the limiting ring 311, and a third groove 31a is formed between the magnet 32 ​​and the limiting ring 311. One end of the coil 33 is located within the third groove 31a. Specifically, the limiting ring 311 and the third groove 31a position the magnet 32, ensuring that the magnet 32 ​​and the coil 33 are coaxial, thus optimizing the distribution of the electromagnetic induction magnetic field. Through this arrangement, the limiting ring 311 and the groove ensure that the magnet 32 ​​and the coil 33 are coaxial, resulting in uniform magnetic flux variation and improved power generation efficiency; it also reduces the impact of vibration, enhances the stability of the power generation components, and ensures stable power generation under complex sea conditions.

[0077] It should be noted that the movable baffle 31 and the upper floating body 1 are sealed together. There are no restrictions on the specific sealing measures and sealing structures. As long as the first power generation component 3 is in a closed condition and seawater can be prevented from seeping in.

[0078] Combination Figure 8 Another aspect of this utility model provides a breakwater assembly, comprising at least two portable breakwaters connected by a pontoon 7. The pontoon 7 is connected to a crossbar 6 of the portable breakwaters, and the crossbar 6 passes through a through-hole 1b of each portable breakwater. A sealing element is provided at the through-hole 1b, which is fitted onto the crossbar 6 and seals the through-hole 1b. Adjacent breakwaters are connected by the pontoon 7, and the sealing element (not shown in the figure) seals the through-hole 1b to prevent seawater from entering. The connection method between the crossbar 6 of adjacent breakwaters and the pontoon 7 is not limited here; it can be a fixed connection or a rotatable connection, or the crossbars 6 of two adjacent breakwaters can be directly connected, with the connected crossbar 6 fixedly connected to the top of the pontoon 7. The specific form of the sealing element is also not limited, as long as it can cover the through-hole 1b on the side of the upper floating body 1 to prevent seawater from entering the upper floating body 1. This configuration connects multiple breakwaters via pontoons 7, which are then connected to crossbars 6, enhancing wave protection capabilities, ensuring energy conversion efficiency, and improving the overall stability of the breakwater assembly. This allows for adaptation to various application scenarios. Especially during high waves, the linkage system balances the load, preventing damage from single-point overload.

[0079] In a preferred embodiment, the crossbar 6 is rotatably connected to the pontoon 7. Alternatively, after two adjacent crossbars 6 are fixedly connected to the top of the pontoon 7, the included angle between the two adjacent crossbars 6 can rotate. The specific method of rotation is not limited here, such as a ball joint connection (not shown in the figure). With this configuration, when multiple portable breakwaters are connected sequentially by multiple pontoons 7 to form a breakwater assembly, the breakwater assembly can adapt to the terrain or be positioned along the perimeter of the ship, improving the overall flexibility of the application and the stability after installation.
