How to efficiently develop and utilize ocean energy has attracted increasing attention both domestically and internationally. my country has also gradually increased its research and development efforts in marine resources. However, due to the low energy density and strong regional characteristics of marine resources, their development remains challenging and limited to some extent. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wave pressure power generation module and a breakwater for installing the wave pressure power generation module, which utilizes near-shore wave energy to convert it into electrical energy.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a wave pressure power generation module, including a shell, a top support plate, an elastic support, a permanent magnet bracket, permanent magnet blocks, a coil support, and a coil. An annular coil support is set inside the shell, and the coil is evenly wound on the coil support. A through hole is opened at the top of the shell corresponding to the cavity inside the annular coil support. The top of the elastic support is connected to the bottom edge of the top support plate, and the bottom is connected to the through hole at the top of the shell. The permanent magnet bracket is connected to the center of the bottom surface of the top support plate, and several long strip permanent magnet blocks are hung at the bottom of the permanent magnet bracket. The long strip permanent magnet blocks are suspended in the shell through the through holes and can move up and down in the shell as the elastic support is compressed, so that the coil evenly wound on the coil support cuts the magnetic field lines to generate electricity during the up and down movement of the permanent magnet blocks.

[0005] The top support plate is a circular thin steel plate, and the elastic bracket is annular with springs evenly arranged inside.

[0006] A breakwater with the aforementioned wave pressure power generation module includes a wave-breaking block, a wave-stopping plate, a water-stopping strip, and a wave pressure power generation module. The wave-breaking block is a regular hexagonal prism, which is rigidly connected vertically to the bottom regular hexagonal wave-stopping plate. The bottom of each corner of the wave-stopping plate is connected to the top support plate of the wave pressure power generation module. The power generation module serves to support the wave-stopping plate. A water-stopping strip is set between adjacent wave-stopping plates, which flexibly connects adjacent wave-stopping plates while serving to stop water. Multiple wave-stopping plates are spliced ​​together to form the upstream face structure of the breakwater.

[0007] The top support plate is a circular thin steel plate, with its top surface connected to three adjacent wave-stopping plates. The three wave-stopping plates are evenly pressed onto the top surface of the top support plate. The wave pressure power generation module is arranged at the corner where the wave-stopping plates are spliced ​​with the adjacent wave-stopping plates. The top of the wave pressure power generation module supports the wave-stopping plates, and the bottom is fixed to the concrete cushion layer. The inlet and outlet cables of each power generation module are connected to the control box in the cable trench set downstream of the breakwater wall through the pre-embedded cable pipe in the concrete cushion layer. A transition zone and a backfill zone are set sequentially downstream of the concrete cushion layer, forming the main structure of the breakwater.

[0008] The wave-breaking blocks are regularly arranged on the upstream water-facing side of the breakwater and are rigidly connected to the wave-damping plate vertically, converting the wave force acting on its surface in an uncertain direction into pressure along the normal direction of the wave-damping plate.

[0016] like Figure 1 As shown, the wave pressure power generation module of the present invention includes a shell 8, a top support plate 5, an elastic support 6, a permanent magnet bracket 7, a permanent magnet block 9, a coil support 11, and a coil 10. The shell 8 is provided with an annular coil support 11, and the coil 10 is evenly wound on the coil support 11. A through hole is opened at the top of the shell 8 corresponding to the cavity inside the annular coil support. The top of the elastic support 6 is connected to the bottom edge of the top support plate 5, and the bottom is connected to the through hole at the top of the shell 8. The permanent magnet bracket 7 is connected to the center of the bottom surface of the top support plate 5. Several long strip permanent magnet blocks 9 are hung at the bottom of the permanent magnet bracket 7. The long strip permanent magnet blocks 9 are suspended in the shell 8 through the through hole and can move up and down in the shell 8 with the compression of the elastic support 6, so that the coil 10 evenly wound on the coil support 11 cuts the magnetic field lines to generate electricity during the up and down movement of the permanent magnet blocks 9.

[0017] Preferably, the top support plate 5 is a circular thin steel plate, and the elastic support is annular with springs evenly arranged inside.

[0018] like Figure 2 , 3 As shown, a breakwater equipped with the aforementioned wave pressure power generation module includes a wave-breaking block 1, a wave-stopping plate 2, a water-stopping strip 3, and a wave pressure power generation module 4. The wave-breaking block is a regular hexagonal prism, which is rigidly connected vertically to the bottom regular hexagonal wave-stopping plate 2. Each corner of the wave-stopping plate 2 is connected to the top support plate 5 of the wave pressure power generation module 4. The power generation module serves to support the wave-stopping plate. A water-stopping strip 3 is set between adjacent wave-stopping plates 2, which flexibly connects adjacent wave-stopping plates while serving to stop water. Multiple wave-stopping plates 3 are spliced ​​together to form the upstream structure of the breakwater.

[0019] Preferably, the top support plate 5 is a circular thin steel plate, and its top surface is connected to three adjacent wave-stopping plates 2. The three wave-stopping plates 2 are evenly pressed on the top surface of the top support plate. The wave pressure power generation module 4 is arranged at the corner where the wave-stopping plate and the adjacent wave-stopping plate are spliced. The top of the wave pressure power generation module supports the wave-stopping plate, and the bottom is fixed on the concrete cushion layer 13. The inlet and outlet cables of each power generation module are connected to the control box 17 set in the cable trench downstream of the breakwater wall 16 through the pre-embedded cable pipe 12 in the concrete cushion layer. The downstream of the concrete cushion layer is provided with a transition area 14 and a backfill area 15 in sequence, which constitute the main structure of the breakwater.

[0020] The wave-breaking blocks 1 are regularly arranged on the upstream water-facing side of the breakwater and are rigidly connected to the wave-stopping plate 2 vertically, converting the wave force acting on its surface in an uncertain direction into pressure along the normal direction of the wave-stopping plate.

[0021] Specifically, the wave-breaking block 1 is rigidly connected vertically to the wave-stopping plate 2. A water-stopping strip 3 is set between adjacent wave-stopping plates 2 to stop water flow. A power generation module 4 is set on the bottom surface of the corner of the wave-stopping plate 2. The power generation module 4 consists of a top support plate 5, an elastic support 6, a permanent magnet bracket 7, a permanent magnet block 9, a shell 8, a coil bracket 11, and a coil 10. The top surface of each top support plate 5 evenly supports the corners of three adjacent wave-stopping plates 3. The center of the bottom surface of the top support plate 5 is connected to the permanent magnet bracket 7. Several long strip permanent magnet blocks 9 are hung at the bottom of the permanent magnet bracket 7. The elastic support 6 is ring-shaped, with its top connected to the edge of the top support plate 5 and its bottom connected to the shell 8. A ring-shaped coil bracket 11 is set inside the shell, and the coil 10 is evenly wound on the coil bracket 11. The wave-breaking block 1 is positioned facing the water's edge. Under the action of the waves, it transmits wave pressure to the wave-stopping plate 2, causing the wave-stopping plate 2 to tend to move vertically downwards. Under the pressure of the wave-stopping plate 2, the top support plate 5, along with the permanent magnet bracket 7 and the permanent magnet block 9, moves downwards. Meanwhile, the elastic support 6 connected to the bottom periphery of the top support plate 5 pushes the top support plate 5 and the permanent magnet bracket 7 and permanent magnet block 9 upwards after the wave pressure weakens, until the original balance is restored. The coil 10, fixed and evenly wound on the coil bracket 11, cuts magnetic field lines to generate electricity during the up-and-down movement of the permanent magnet block 9. The breakwater uses wave-breaking blocks 1 as the facing structure instead of traditional T-shaped blocks. Multiple wave-stopping plates 2 are spliced ​​together, forming the upstream face structure of the breakwater together with the waterstop 3 and wave-breaking blocks 1. Multiple power generation modules 4 are set on the bottom of the upstream face. The foundation of the power generation module 4 is set with a concrete cushion layer 13, and cable pipes 14 are buried in the concrete cushion layer 13. The cables laid in the concrete cushion layer 13 connect the power generation module 4 and the control box 17. Downstream of the concrete cushion layer 13, a transition area 14 and a backfill area 15 are set as the main structure of the breakwater. A wave-breaking wall 16 is set at the top upstream of the breakwater. A cable trench is reserved at the bottom of the wave-breaking wall. The control box 17 is set in the cable trench. The control box 17 converts the electrical energy generated by the power generation module into stable output electrical energy through rectifiers, capacitors, voltage stabilizers, etc., and connects to external power equipment through cables.

[0022] The wave-breaking blocks are the wave-weakening protective structures of this invention. They are regularly arranged on the upstream water-facing side of the breakwater structure and rigidly connected to the wave-stopping plates. They convert the wave force acting on their surface in an uncertain direction into pressure in the direction normal to the wave-stopping plates. The wave-stopping plates are the pressure transmission structures of this invention. They transmit the pressure from the wave-breaking blocks to the power generation module connected to their bottom. Water-stopping strips are set between adjacent wave-stopping plates to stop water flow and together with the wave-stopping plates, they form the upstream surface of the breakwater structure of this invention. Under the pressure of the wave-stopping plates, the top support plate of the power generation module moves downward along with the permanent magnet bracket and permanent magnet blocks. The elastic supports connected around the bottom of the top support plate push the top support plate and the permanent magnet bracket and permanent magnet blocks connected to the top support plate upward after the wave pressure weakens until the original equilibrium is restored. A coil, fixed and uniformly wound on a coil support, generates electricity by cutting magnetic field lines during the up-and-down movement of a permanent magnet block. The concrete cushion layer is the foundation layer of the power generation module in this invention, supporting the outer shell of the power generation module to prevent it from moving. The cable conduit is a thin tube structure pre-embedded in the concrete cushion layer of the breakwater of this invention. The cable buried in the conduit connects the power generation module and the control box, transmitting the current generated by the power generation module to the control box. The wave-breaking wall is the wave-breaking structure at the top of the breakwater of this invention. A cable trench is set downstream of it to house the control box and cables connected to external power transmission and transformation equipment. The control box is the integrated control structure of this invention, containing a rectifier, capacitor, voltage regulator, etc., which converts the electrical energy generated by the power generation module into stable output electrical energy through rectification, filtering, and voltage stabilization processes. The transition zone and backfill zone of the breakwater are the main body of the breakwater structure, and their shape or gradation can be adjusted according to the terrain, geological conditions, and material source conditions.

[0023] For example, a breakwater in China is designed to be 3.5m high and 130m long. This invention relates to the wave pressure power generation device and the breakwater structure incorporating this device. The wave-breaking block is 1.0m high, with a hexagonal cross-section and a side length of 0.3m. The wave-breaking block is made of reinforced concrete and has a hollow internal structure. The wall thickness of the wave-breaking block is 0.1m. The wave-stopping plate is also a hexagonal reinforced concrete plate with a side length of 0.6m and a thickness of 0.15m. An externally attached rubber waterstop is used, installed on the water-facing side of adjacent wave-stopping plates. The top support plate of the power generation module is made of 304L stainless steel, while the permanent magnet support and coil support are made of fluoroplastic. The elastic support is internally equipped with a stainless steel high-strength spring assembly with an axial deformation range of 0–7cm. The foundation concrete pad of the power generation module is 0.5m thick, using C15 plain concrete. The transition layer downstream of the concrete pad is a 1.2m thick graded material with a maximum particle size of 25mm, and the backfill material downstream of this layer is excavated material. The cable conduit embedded in the concrete foundation is made of PVC pipe with an inner diameter of 25mm.

[0024] This invention relates to a wave pressure power generation module and a breakwater incorporating this module, providing a novel method for converting ocean wave energy into electrical energy. While fully utilizing the breakwater's functions, it also enables the collection and utilization of ocean wave energy resources. The dimensions of the wave pressure power generation module and the breakwater structure, as well as the materials used, can be designed and adjusted according to the wave characteristics, topographical and geological conditions, and material availability of the breakwater's location, making it highly adaptable.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The patent scope of the present invention should not be limited by these embodiments. That is, all equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.
