Description

Technical Field

[0001] This invention relates to the field of wave energy generation technology, specifically to a biomimetic seaweed-style piezoelectric ceramic power generation grid for fixed breakwaters. Background Technology

[0002] Currently, reducing greenhouse gas emissions and reducing dependence on fossil fuels has become a common consensus and an urgent task for the international community. Developing and utilizing abundant and widely distributed renewable energy sources is not only a key path to achieving emission reductions, but also a choice to ensure national energy security and promote sustainable economic development. Among many renewable energy sources, tidal energy has unique advantages due to its extremely high predictability and energy density. Unlike intermittent solar and wind power, tides are driven by the gravitational pull of the moon and the sun, and their tidal cycles are stable and reliable, providing near-constant baseload power, making them an ideal source for stable power supply. With the popularization of the Internet of Things (IoT), sensing technology, and automated control, modern breakwaters, ports, waterways, and other marine infrastructure have deployed a large number of intelligent devices for monitoring hydrological and meteorological conditions, structural health, and ship traffic. These sensors, which constitute the nerve endings of the "smart ocean," have extremely high requirements for a continuous and stable power supply. Traditional cable power supply or battery replacement solutions are difficult to implement in remote areas and have high maintenance costs, becoming a bottleneck restricting the development of the marine IoT.

[0003] Breakwaters, as readily available marine engineering structures widely found along coastlines, are themselves located in the energy-intensive intertidal zone. Integrating power generation devices with breakwaters can utilize existing structures, significantly reducing the civil engineering costs and environmental footprint of tidal power generation, achieving "dual-purpose breakwaters." Seaweed in the water, with its unique leaf structure, sways randomly under the influence of water currents, reducing the impact of the water flow on the leaves and ensuring it is not washed away. This biomimetic design can be applied to breakwaters to reduce the impact of tides on shoreline structures. Biomimetic seaweed-inspired piezoelectric ceramic power generation grids can be used to achieve erosion resistance and localized stable power generation for breakwaters. Summary of the Invention

[0004] To address the shortcomings of the existing technology, the present invention aims to propose a biomimetic seaweed-inspired piezoelectric ceramic power generation grid for fixed breakwaters, which aims to solve the problems of how to utilize tidal energy to provide constant base load power and reduce the impact of tides on shore structures.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A biomimetic seaweed-type piezoelectric ceramic power generation grid for fixed breakwaters includes a wave-dissipating box, piezoelectric ceramic seaweed, a counterweight assembly, a top anchoring mechanism, and wiring terminals. The wave-dissipating box is a square box arranged vertically at an angle, with an internal cavity structure open on the front.

[0007] The inside of the soundproof box is fixedly equipped with a grid frame, which divides the internal cavity of the soundproof box into several tunnel cavities. All tunnel cavities are regularly distributed in a square array. The rear ends of each tunnel cavity in the same column are connected and communicate with each other through a through cavity inside the soundproof box.

[0008] The inner side of the tunnel cavity is provided with a set of piezoelectric ceramic seaweed, and the inner side of the through cavity is provided with multiple sets of the same piezoelectric ceramic seaweed. The multiple sets of piezoelectric ceramic seaweed located in the same through cavity are arranged sequentially from top to bottom at intervals. Each set of piezoelectric ceramic seaweed includes multiple piezoelectric ceramic seaweeds that are regularly distributed in a staggered manner.

[0009] Each piezoelectric ceramic seaweed located inside the tunnel cavity is installed on the bottom surface of the tunnel cavity, while each piezoelectric ceramic seaweed located inside the through cavity is installed on the rear side wall of the through cavity.

[0010] The top rear side of the breakwater has a probing edge that extends horizontally relative to its rear sidewall. A top anchoring mechanism is located inside the probing edge. A counterweight assembly is located below the breakwater and connected to the bottom of the breakwater.

[0011] Furthermore, the wave-damping box includes a top plate, a bottom plate, a left side plate, a right side plate, and a rear side plate. The rear side plate is a square flat plate with its upper middle part tilted backward. The left side plate and the right side plate are both parallelograms with equal dimensions. The left side plate and the right side plate are arranged opposite each other on the front side of the left and right ends of the rear side plate.

[0012] The top plate and bottom plate are arranged in parallel and staggered and fixed to the front sides of the upper and lower ends of the rear side plate respectively. The left and right ends of the top plate and bottom plate are fixedly connected to the corresponding ends of the left side plate and right side plate to form a whole.

[0013] Furthermore, the grid frame includes vertical plates and horizontal plates, both of which are strip-shaped flat plates and are provided in multiples. The vertical plates are parallelogram structures that match the internal cavity of the washout box.

[0014] Each upright plate is arranged at equal intervals from left to right on the inner side of the soundproof box. The upright plates are arranged vertically, and their rear end faces are connected to the rear side plates to form a whole. Each upright plate divides the internal cavity of the soundproof box into multiple independent strip-shaped grooves.

[0015] The horizontal plates are arranged at equal intervals from top to bottom. Each horizontal plate intersects with each vertical plate in a cross shape and is connected to form a whole. The left and right ends are respectively connected to the inner side wall of the soundproof box. The horizontal plates divide the strip groove to form the tunnel cavity.

[0016] Furthermore, both the breakwater box and the grid frame are made of rigid, corrosion-resistant PE material or fiberglass, and the probe edge is a rectangular plate integrally formed with the breakwater box.

[0017] The width of the vertical plate is greater than the width of the horizontal plate. The front end face of each vertical plate is flush with the front end face of all the horizontal plates. The rear end of the vertical plate protrudes backward relative to the horizontal plate. The through cavity is formed between the rear end face of the horizontal plate and the rear side plate.

[0018] Furthermore, the piezoelectric ceramic seaweed includes a base, an elastic support body, a piezoelectric ceramic plate, and a flexible shell. The base is fixedly embedded on the upper surface of the horizontal plate or the front surface of the rear plate, and the elastic support body is located on the outer surface of the base.

[0019] A set of piezoelectric ceramic plates is provided on both sides of the elastic support body. The set of piezoelectric ceramic plates includes multiple piezoelectric ceramic plates that are linearly spaced along the length of the elastic support body. Each piezoelectric ceramic plate is electrically connected to the terminal block through a bridge rectifier.

[0020] One end of the flexible shell is fixedly and sealed to the surface of the base, encapsulating the elastic support and the piezoelectric ceramic plate inside it.

[0021] Furthermore, the elastic support body includes an elastic rubber sheet and a spring. The elastic rubber sheet has a rectangular structure, with one end fixedly connected to the surface of the base. There are two springs, symmetrically arranged inside both sides of the elastic rubber sheet along its length, with one end of each spring fixedly connected to the surface of the base.

[0022] The flexible outer shell is a sheet-like shell that imitates the shape of seaweed. The two sides of the flexible outer shell along its length have a serrated structure, and the other end away from the base is pointed.

[0023] Furthermore, the top anchoring mechanism includes multiple anchor rods, each anchor rod is equipped with a pad and a locking nut, and the probe has mounting holes that are equal in number and correspond one-to-one with the number of anchor rods, and all mounting holes are distributed laterally at equal intervals.

[0024] During installation, vertical holes need to be drilled at the top of the breakwater slope, anchoring agent is placed in the holes, and then the anchor rod is fixed. The upper end of the anchor rod passes through the corresponding installation hole, the pad is placed, and the locking nut is tightened.

[0025] Furthermore, there are four counterweight components, which are respectively located at the four corners of the base plate. Each counterweight component includes a metal ring, a steel cable, and a counterweight block. Through holes are provided at each of the four corners of the base plate, and the metal rings are installed in the corresponding through holes and are movably connected to the base plate.

[0026] One end of the steel cable is connected to a metal ring, and a counterweight is connected to the other end of the steel cable. The weight of the counterweight keeps the back of the breakwater box in contact with the slope surface of the breakwater.

[0027] By adopting the above technical solution, the beneficial technical effects of the present invention are as follows:

[0028] Compared with the prior art, the present invention has the following advantages: The interior of the breakwater box of the present invention forms regularly distributed tunnel cavities by setting a grid frame. The rear ends of the tunnel cavities in the same row are connected by an inclined through cavity. The internal structure of the breakwater box greatly reduces the impact of tides on the breakwater. By arranging piezoelectric ceramic seaweed with a biomimetic structure on the inner walls of the tunnel cavities and the through cavity, the force of the seawater flow inside the breakwater box on the piezoelectric ceramic seaweed is used to provide stable power. The present invention can be deployed over a large area along the coastline to generate considerable power generation. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings:

[0036] Implementation examples, in conjunction with Figures 1 to 6 A biomimetic seaweed-style piezoelectric ceramic power generation grid for fixed breakwaters includes a wave-dissipating box 1, piezoelectric ceramic seaweed 2, a counterweight assembly 3, a top anchoring mechanism 4, and wiring terminals 5. The wave-dissipating box 1 is a vertically inclined square box with an open front cavity structure inside. The back of the wave-dissipating box 1 is attached to the inclined surface of the breakwater. The biomimetic seaweed-style piezoelectric ceramic power generation grid is produced in a modular manner. During installation, the biomimetic seaweed-style piezoelectric ceramic power generation grids are arranged adjacent to each other along the extension direction of the breakwater. Specifically, the wave-dissipating box 1 includes a top plate 11, a bottom plate 12, a left side plate 13, a right side plate 14, and a rear side plate 15. The rear side plate 15 is a square flat plate with the upper middle part inclined backward. The left side plate 13 and the right side plate 14 are both parallelograms with equal dimensions, and the left side plate 13 and the right side plate 14 are arranged opposite each other on the front side of the left and right ends of the rear side plate 15.

[0037] The top plate 11 and the bottom plate 12 are arranged in parallel and staggered positions and are fixed to the front sides of the upper and lower ends of the rear side plate 15, respectively. The left and right ends of the top plate 11 and the bottom plate 12 are fixedly connected to the corresponding ends of the left side plate 13 and the right side plate 14 to form a whole. The ends of the left side plate 13, the right side plate 14, the top plate 11 and the bottom plate 12 are connected end to end to form a closed frame. The rear ends are fixedly and sealed to the corresponding sides of the rear side plate 15 to form a box structure with a square cavity inside.

[0038] In addition, the top rear side of the breakwater box 1 has a protruding edge 16 extending horizontally relative to its rear sidewall. The protruding edge 16 is a rectangular plate integrally formed with the breakwater box 1. The protruding edge 16 on the top rear side of the breakwater box 1 is attached to the top of the breakwater, so that the upper end of the breakwater box 1 is fixed to the breakwater by the top anchoring mechanism 4, and can resist the impact of tides.

[0039] The top anchoring mechanism 4 is located on the inner side of the probe edge 16. The top anchoring mechanism 4 includes multiple anchor rods 41. Each anchor rod 41 is equipped with a pad 42 and a locking nut 43. The probe edge 16 has mounting holes 161 that are equal in number and correspond one-to-one with the number of anchor rods 41. All mounting holes 161 are distributed horizontally at equal intervals.

[0040] During installation, vertical holes need to be drilled at the top of the breakwater slope, and anchoring agent is placed in the holes. Then, the anchor rod 41 is fixed, and the upper end of the anchor rod 41 is passed through the corresponding installation hole 161. The pad 42 is placed and the locking nut 43 is tightened to fix the top of the breakwater box 1 to the top of the breakwater slope. The installation and disassembly operations are simple.

[0041] The counterweight assembly 3 is located below the wave-damping box 1 and connected to the bottom of the wave-damping box 1. There are four counterweight assemblies 3, which are respectively located at the four corners of the base plate 12. Each counterweight assembly 3 includes a metal ring 31, a steel cable 32, and a counterweight block 33. The base plate 12 has through holes at each of its four corners, and the metal ring 31 is installed in the corresponding through holes and movably connected to the base plate 12.

[0042] One end of the steel cable 32 is connected to the metal ring 31, and the counterweight 33 is connected to the other end of the steel cable 32. The gravity of the counterweight 33 keeps the back of the breakwater box 1 in contact with the slope surface of the breakwater. Because the breakwater box 1 is designed with an inclined structure, under the action of the counterweight assembly 3, the back of the breakwater box 1 is kept pressed against the slope of the breakwater, and the breakwater box 1 resists the impact of tides and avoids the breakwater from being directly impacted by sea waves.

[0043] A grid frame 6 is fixedly installed on the inner side of the wave-damping box 1. The grid frame 6 divides the internal cavity of the wave-damping box 1 into several tunnel cavities 71. All tunnel cavities 71 are regularly distributed in a square array. The rear ends of each tunnel cavity 71 in the same row are connected and communicate with each other through a through cavity 72 inside the wave-damping box 1. The tunnel cavities 71 in the same row are interconnected on the inner side. Water in the upper tunnel cavity 71 flows into the lower tunnel cavity 71 through the through cavity 72, and water in the lower tunnel cavity 71 can also flow into the upper tunnel cavity 71 through the through cavity 72. The inside of the wave-damping box 1 is arranged with piezoelectric ceramic seaweed in the horizontal and vertical directions, which can swing randomly under the action of tidal water flow to generate electricity.

[0044] Both the breakwater enclosure 1 and the grille frame 6 are made of rigid, corrosion-resistant PE material or fiberglass. The grille frame 6 includes vertical plates 61 and horizontal plates 62, both of which are strip-shaped flat plates and are provided in multiples. The vertical plates 61 are parallelogram structures that match the internal cavity of the breakwater enclosure 1. The vertical plates 61 are arranged at equal intervals from left to right on the inner side of the breakwater enclosure 1. The vertical plates 61 are arranged vertically, and their rear ends are connected to the rear side plate 15 to form a single unit. Each vertical plate 61 divides the internal cavity of the breakwater enclosure 1 into multiple independent strip-shaped grooves.

[0045] Each horizontal plate 62 is arranged at equal intervals from top to bottom. Each horizontal plate 62 intersects with each vertical plate 61 in a cross shape and is connected to form a whole. The left and right ends are respectively connected to the inner sidewall of the wave-damping box 1. The horizontal plate 62 divides the strip groove to form the tunnel cavity 71.

[0046] The width of the vertical plate 61 is greater than the width of the horizontal plate 62. The front end face of each vertical plate 61 is flush with the front end face of all horizontal plates 62. The rear end of the vertical plate 61 protrudes rearward relative to the horizontal plate 62. The through cavity 72 is formed between the rear end face of the horizontal plate 62 and the rear side plate 15.

[0047] The inner side of the tunnel cavity 71 is provided with a set of piezoelectric ceramic seaweed 2, and the inner side of the through cavity 72 is provided with multiple sets of the same piezoelectric ceramic seaweed 2. The multiple sets of piezoelectric ceramic seaweed 2 located in the same through cavity 72 are arranged in sequence from top to bottom at intervals. Each set of piezoelectric ceramic seaweed 2 includes multiple piezoelectric ceramic seaweed 2 that are regularly distributed in a staggered manner.

[0048] Each piezoelectric ceramic seaweed 2 located in the tunnel cavity 71 is installed on the bottom surface of the tunnel cavity 71, and each piezoelectric ceramic seaweed 2 located in the through cavity 72 is installed on the rear side wall of the through cavity 72.

[0049] The piezoelectric ceramic seaweed 2 includes a base 21, an elastic support 22, a piezoelectric ceramic plate 23, and a flexible outer shell 24. The base 21 is fixedly embedded in the upper surface of the horizontal plate 62 or the front surface of the rear side plate 15, and the elastic support 22 is located on the outer surface of the base 21. Specifically, the upper surface of the horizontal plate 62 and the front side wall of the rear side plate 15 are provided with mounting grooves that match the base 21. The interior of the horizontal plate 62 and the rear side plate 15 has wire holes that communicate with the bottom of each mounting groove. The base 21 is fixedly embedded in the corresponding mounting groove and sealed with resin to prevent seawater from entering.

[0050] A set of piezoelectric ceramic plates 23 is provided on each side of the elastic support 22. The set of piezoelectric ceramic plates 23 includes multiple piezoelectric ceramic plates 23 linearly spaced along the length of the elastic support 22. Each piezoelectric ceramic plate 23 is electrically connected to the terminal 5 through a bridge rectifier. The bridge rectifier is installed inside the base 21. The piezoelectric ceramic plates 23 located on the same elastic support 22 are connected to the bridge rectifier in parallel. The bridge rectifier converts the AC power of the piezoelectric ceramic plates 23 into DC power, which is then transmitted to the energy storage device through the terminal 5 at the top of the damping box 1.

[0051] The elastic support body 22 includes an elastic rubber sheet and a spring. The elastic rubber sheet has a rectangular structure, with one end fixedly connected to the surface of the base 21. There are two springs, symmetrically arranged inside both sides of the elastic rubber sheet along its length. One end of each spring is fixedly connected to the surface of the base 21. The springs serve as the skeleton of the elastic support body 22. Under the action of water flow, the elastic support body 22 and the flexible outer shell 24 swing and vibrate, causing the piezoelectric ceramic to continuously generate electricity.

[0052] One end of the flexible outer shell 24 is fixedly and sealed to the surface of the base 21, serving as an insulating protective layer for the piezoelectric ceramic seaweed 2. The flexible outer shell 24 encapsulates the elastic support 22 and the piezoelectric ceramic plate 23 within it. The flexible outer shell 24 is a sheet-like shell in the shape of seaweed, with serrated structures on both sides along its length and a pointed end away from the base 21.

[0053] During operation, waves impact the wave-damping box 1 and its inner grid frame 6. Water flows into the lower tunnel cavity 71, impacting the electro-ceramic seaweed 2 within the cavity and causing it to oscillate. The water then reaches the through-cavity 72 and flows upwards, impacting the electro-ceramic seaweed 2 within the through-cavity 72 and causing it to oscillate. Alternatively, it may flow from the through-cavity 72 into the upper tunnel cavity 71. The flow of waves within the wave-damping box 1 effectively dampens and prevents waves. The water flowing inside also causes the electro-ceramic seaweed 2 to oscillate, vibrating the piezoelectric ceramic plate 23 to generate electricity, providing continuous power output. The piezoelectric ceramic seaweed 2 also reduces the kinetic energy of the water flow, lowering its impact force.
