Description

Technical Field

[0001] The present invention belongs to the technical field of wave energy power generation equipment, and more specifically, relates to a multifunctional offshore wave energy conversion and protection system and method. Background Art

[0002] Wave energy, as a clean and renewable marine energy source, has great development potential. The source of wave energy is mainly the waves generated when the wind blows over the ocean surface. These waves carry huge amounts of energy, mainly manifested as the vertical displacement (potential energy) of the waves and the horizontal flow of water (kinetic energy). Wave energy conversion technology aims to capture this energy and convert it into electrical energy or other available forms of energy.

[0003] With the intensification of global climate change and the increasing demand for ocean resource development, traditional single-functional marine engineering systems can no longer meet the dual needs of carbon neutrality goals and coastal zone sustainable development. Against this background, a multifunctional offshore wave energy conversion system integrating wave energy power generation, coastal protection, and ecological restoration has become the research focus in the international marine engineering field.

[0004] The global energy transition is accelerating, and the carbon neutrality goal has made ocean energy development inevitable. It is predicted that by 2050, wave energy will need to contribute at least 3.5% of the global electricity demand, driving the "seawall-power generation" integrated design to become a key technical path. At the same time, the threat of extreme climate is escalating. In 2024, the global average sea level rise rate reached 4.8 mm / year, resulting in 30% of coastal cities facing the risk of tidal disasters, and the damage rate of traditional breakwaters under extreme sea conditions exceeds 65%.

[0005] At present, wave energy development faces many technical difficulties, which seriously restrict its large-scale commercial application. The energy conversion efficiency of the mainstream oscillating water column (OWC) device is low, averaging only 18%-25%, and under irregular wave conditions, the power fluctuation rate exceeds 40%, resulting in insufficient power generation stability. In addition, the mechanical transmission system has poor durability in the marine salt spray environment, with a service life of only 5-8 years, far lower than the 20 years of onshore wind power equipment. Under extreme sea conditions, the adaptability of existing wave energy devices is poor. When the wave height exceeds 10 meters, 80% of the devices will automatically shut down, resulting in an average annual power generation loss of 27%. At the same time, the reliability of the anchoring system is insufficient, and its failure has become the main failure mode, accounting for 43% of the total accidents. The existing wave energy development technology urgently needs to make breakthroughs in efficiency, durability and stability; traditional coastal protection projects also face many challenges. The construction of concrete breakwaters has had a significant negative impact on the ecological environment, resulting in the degradation of 85% of intertidal zone biological habitats, which has seriously damaged the balance of the marine ecosystem. In addition, artificial hard revetments have changed the nearshore flow field, further exacerbating the erosion rate of local coasts to 4 meters per year. From an economic perspective, the operation and maintenance costs of a single protective facility are extremely high, costing $120-200 per meter per year, and 70% of the world's coastal areas cannot afford such high costs in the long term, which not only limits the sustainability of coastal protection projects, but also highlights the dual dilemma of traditional protection models in terms of ecology and economy. Summary of the invention

[0017] Further, the intelligent buffer module is made of a damping material and forms a honeycomb structure inside, and the honeycomb is filled with magnetorheological fluid.

[0018] According to the second aspect of the present invention, there is provided a multifunctional offshore wave energy conversion and protection method, which is realized by applying the multifunctional offshore wave energy conversion and protection system described above, and includes the following steps:

[0019] S100: The sea waves act on the conversion and protection device, causing adjacent two intelligent buffer modules to generate up-and-down undulation and swaying motions;

[0041] Embodiment 1

[0042] As Figures 1-3 shown, an embodiment of the present invention provides a multifunctional offshore wave energy conversion and protection system, including a plurality of conversion and protection devices 1. The adjacent conversion and protection devices 1 are hinged through a flexible connection member 2. The use of the flexible connection member 2 enables multi-dimensional relative movement between the conversion and protection devices 1 while maintaining the connectivity of the overall structure. It can effectively adapt to complex working conditions and dynamically changing environments. In the wave energy conversion and protection device, the flexible connection member 2 can stretch and adjust the angle with the undulation of the waves, thereby improving the energy capture efficiency; through the hinged manner of the flexible connection member 2, a plurality of conversion and protection devices 1 can work together to form a dynamic system, which can better capture and utilize external energy (such as wave energy), and optimize the energy conversion process by adjusting the length and angle of the telescopic rod.

[0043] As Figures 4-6 shown, the conversion and protection device 1 includes two intelligent buffer modules 11 and a transmission plate 12. Each top surface of the intelligent buffer module 11 is provided with two first ball hinge connection devices 15. The bottom surface of the first ball hinge connection device 15 is fixedly installed with a connecting plate 151, and the bottom of the connecting plate 151 is fixedly installed with a sliding block 152; the top of the intelligent buffer module 11 is provided with a chute 111 matching the sliding block 152, allowing the first ball hinge connection device 15 to slide relative to the intelligent buffer module 11; each side of the bottom of the transmission plate 12 is fixedly installed with two second ball hinge connection devices 16. A support transmission rod 13 is provided between the connecting plate 151 and the transmission plate 12. The support transmission rod 13 is ball-hinged to the connecting plate 111 through the first ball hinge connection device 15, and the support transmission rod 13 is ball-hinged to the transmission plate 12 through the second ball hinge connection device 16. Under the action of the sea waves, the two intelligent buffer modules 11 can adapt to different angles and positions. The support transmission rod 13 is ball-hinged to the connecting plate 151 and the transmission plate 12 through the first ball hinge connection device 15 and the second ball hinge connection device 16 respectively, forming an efficient force transmission path, which not only optimizes the force transmission efficiency but also ensures the uniform distribution of force during the whole operation process, reducing the risk of failure caused by local stress concentration.

[0044] Further, the two intelligent buffer modules 11 are rotatably connected through a shaft transmission assembly 14. The shaft transmission assembly 14 includes connecting ear plates 141 provided at the ends of the intelligent buffer modules 11 and parallel to each other. Each connecting ear plate 141 is provided with a through hole. The two intelligent buffer modules 11 are connected to each other in a rotational manner by a second shaft 142 passing through the through holes in the connecting ear plates 141, thereby forming a transmission structure with a flexible angle adjustment. This structure not only ensures the reliable connection between the modules but also allows the intelligent buffer module 11 to dynamically adjust its attitude according to the direction and intensity of the waves, so as to better capture and convert wave energy.

[0045] Further, two parallel lifting lugs 121 are fixedly installed in the middle of the transmission plate 12. The lifting lugs 121 are provided with round holes. A roller flywheel power generation device 17 is provided between the transmission plate 12 and the shaft transmission assembly 14. The roller flywheel power generation device 17 is rotatably connected to the lifting lugs 121 through a first shaft 122, and the roller flywheel power generation device 17 is rotatably connected to the connecting ear plates 141 through a second shaft 142.

[0046] Specifically, the transmission plate 12 is ball-joint connected to the support transmission rod 13 and rotatably connected to the roller flywheel power generation device 17 to form a toggle transmission mechanism, which efficiently converts the small displacement at the input end into a large-range displacement at the output end. On the one hand, by using the geometric lever principle and non-linear amplification characteristics, an exponential displacement increase is achieved when approaching the "dead point", which is suitable for scenarios of rapid expansion or contraction. On the other hand, by optimizing the conversion of force and displacement, sacrificing part of the input force in exchange for a larger output displacement, and having a self-locking characteristic, it can maintain a stable position without continuous force application at a specific angle. In addition, this transmission member also has spatial compactness. Its folding structure and multi-degree-of-freedom integrated design not only significantly reduce the occupied space in the non-working state but also achieve complex trajectory output through multi-stage series or parallel connection while maintaining the overall structure simple and efficient.

[0047] Specifically, acting on the intelligent buffer module 11, the intelligent buffer module 11 will generate up-and-down and swaying motions due to the undulation and impact of the waves. The transmission plate 12 moves relative to the intelligent buffer module 11 through the first ball-joint connection device 15, the support transmission rod 13, and the second ball-joint connection device 16, and efficiently transfers the mechanical motion of the intelligent buffer module 11 to the roller flywheel power generation device 17. The linkage of these devices causes the roller flywheel power generation device 17 to undergo a large-displacement motion, thereby driving the generator in the device to operate efficiently and converting mechanical energy into electrical energy.

[0048] Furthermore, a plurality of connecting rods 19 are provided between the two supporting transmission rods 13 on each intelligent buffer module 11, and the plurality of connecting rods 19 form a maintenance ladder, which provides a direct and convenient passage for maintenance personnel to quickly reach the key parts of the equipment for inspection and maintenance. This design reduces the preparation work such as building temporary scaffolding, significantly shortens the maintenance time, takes into account the complex working environment at sea, and can adapt to the displacement or deformation that may occur during the operation of the equipment.

[0049] Furthermore, if Figure 5 As shown, a connecting column 112 is disposed at the other end of the intelligent buffer module 11 , and the flexible connecting member 2 between the two conversion and protection devices 1 is fixedly connected to the intelligent buffer module 11 via the connecting column 112 .

[0050] Furthermore, the flexible connection member 2 includes but is not limited to a spring, rubber or cable structure. The flexible connection member 2 (such as a spring, rubber or cable structure) can effectively absorb and buffer external impact forces, reduce the impact of waves or other external forces on the conversion and protection device 1, thereby protecting the stability and safety of the device. The flexible connection member 2 can provide elastic support, allowing the device to freely expand or deform within a certain range, while maintaining the stability of the connection, absorbing energy, and reducing equipment damage caused by external force impact, thereby improving the reliability and service life of the entire system.

[0051] Specifically, the roller flywheel power generation device 17 is a composite energy management system that integrates flywheel energy storage technology, roller low-friction transmission, and inertial mass control. When the device is running, the coordinated movement of the transmission plate 12 and the intelligent buffer module 11 drives the roller flywheel power generation device 17 to move through the pin shaft, and the flywheel will quickly convert these mechanical energies into its own rotational kinetic energy for storage. In terms of achieving efficient power generation, the roller flywheel power generation device uses a set of precise electromagnetic conversion devices. When the flywheel rotates at high speed, the powerful kinetic energy it generates drives the power generation components connected to it to operate. The power generation components use the principle of electromagnetic induction. The rapidly rotating coil in the magnetic field cuts the magnetic flux lines, thereby accurately converting the mechanical energy of the flywheel rotation into electrical energy. This electromagnetic conversion method is highly efficient and stable, and can convert the kinetic energy stored in the flywheel into available electrical energy to the maximum extent, greatly improving the efficiency of energy utilization.

[0052] Furthermore, an energy storage device 18 is provided at the top of the transmission plate 12. The energy storage device 18 is connected to the roller flywheel power generation device 17. During the operation of the roller flywheel power generation device 17, mechanical energy is efficiently converted into electrical energy through a specific electromagnetic induction principle, and then the generated electrical energy will be timely transmitted and stored in the energy storage device 18; the electrical energy stored in the energy storage device 18 has multiple uses. On the one hand, it can provide stable power support for various sensors (such as radar, lidar, cameras, and ultrasonic sensors) of the intelligent buffer module 11, ensuring that it can monitor the surrounding environment in real time and operate normally, and can also provide key data support for the intelligent buffer module 11 to make buffer adjustment decisions in a timely and accurate manner. On the other hand, this electrical energy can also supply power to the lighting equipment on the bridge, ensuring the lighting requirements of the bridge at night or in dim light environments, improving the safety and convenience of bridge passage, and providing a clear view for passing vehicles and pedestrians.

[0053] Specifically, advanced energy storage media are adopted inside the energy storage device 18, such as high-performance lithium-ion batteries or supercapacitors. These energy storage media have the characteristics of high energy density, fast charge and discharge capabilities, and long cycle life, and can effectively store the electrical energy generated by the roller flywheel power generation device 17 and quickly release it when needed. The energy storage device 18 is equipped with an intelligent power supply and control system, which can monitor the state of the energy storage unit (such as voltage, current, temperature, etc.) in real time and intelligently distribute electrical energy according to system requirements. Through the built-in sensors and microprocessors, the system automatically adjusts the charge and discharge process to ensure the safe operation of the energy storage unit while optimizing the energy utilization efficiency. The energy storage device 18 also integrates an energy conversion module, which can convert the electrical energy generated by the roller flywheel power generation device 17 into a voltage and current form suitable for storage. At the same time, this module is also responsible for converting the stored electrical energy into an electrical energy form suitable for the sensors in the intelligent buffer module 11 and the bridge lighting equipment, ensuring the stability and compatibility of power supply.

[0054] Furthermore, the intelligent buffer module 11 is internally provided with multiple sensors, including but not limited to radar, cameras, ultrasonic sensors, force sensors, temperature sensors, and inclination sensors, which are used to monitor the position, speed, and movement trajectory of surrounding obstacles in real time and can identify potential collision targets such as ships; the radar sensor can monitor the position, speed, and movement trajectory of distant obstacles in real time by emitting and receiving electromagnetic waves, and is used to give early warnings of potential collision targets and provide time for the dynamic adjustment of the buffer module; the camera sensor captures image or video data through optical imaging and is used for target recognition and environmental monitoring, for the automatic recognition and classification of targets such as ships, further improving the intelligence level of the system; the ultrasonic sensor emits and receives ultrasonic waves to detect the distance and speed of nearby obstacles and is suitable for close-range monitoring, effectively complementing the blind area of the radar sensor; the force sensor is used to monitor the force acting on the buffer module in real time, can accurately measure the magnitude and direction of the collision force, and dynamically adjusts the buffer hardness according to the collision intensity to protect the equipment and structure; the temperature sensor is used to monitor the ambient temperature and the internal temperature of the equipment to ensure that it is within the optimal operating temperature range; the inclination sensor is used to detect the tilt angle of the equipment to ensure its stability in a complex environment.

[0055] Furthermore, the intelligent buffer module 11 is made of damping material and forms a honeycomb structure inside. The honeycomb is filled with magnetorheological fluid, combining the excellent energy dissipation characteristics of the damping material, the high strength and lightweight advantages of the honeycomb structure, and the intelligent controllable rheological characteristics of the magnetorheological fluid, realizing the dynamic adjustment of the buffer performance and efficient energy absorption. The damping material provides the basic shock absorption function for the module, while the honeycomb structure further disperses the impact force, reduces stress concentration, and enhances the flow damping effect of the magnetorheological fluid through its multi-channel design. The magnetorheological fluid can quickly change its viscosity under the action of an external magnetic field, thus realizing the controllability of the damping force, enabling the buffer module to be dynamically adjusted according to different working conditions, adapting to high impact loads and complex dynamic environments. This integrated design not only improves the buffer performance but also protects bridges and other fixed structures.

[0056] Specifically, the magnetorheological fluid is a kind of intelligent material, which is composed of tiny soft magnetic particles with high magnetic permeability and low hysteresis and a non-magnetic conductive liquid. In the absence of an external magnetic field, the magnetorheological fluid exhibits liquid fluidity and can flow freely within the honeycomb structure, further enhancing the flexibility and adaptability of the buffer module. However, when subjected to an external magnetic field, the magnetic particles in the magnetorheological fluid will quickly arrange into a chain-like structure, causing a significant change in the viscosity and yield strength of the magnetorheological fluid instantaneously, changing from a liquid state to a solid-like state. This rapid and reversible rheological characteristic enables the intelligent buffer module 11 to adjust its own buffer performance in real time by adjusting the magnetic field strength according to the actual impact situation, achieving an intelligent buffer effect.

[0057] Furthermore, the device for adjusting the magnetorheological fluid mainly includes an electromagnetic coil, a power supply and control system, and a sensor feedback system. Its working principle is to monitor the force and state of the buffer module in real time through the sensor. The control system adjusts the current of the electromagnetic coil according to the feedback signal, thereby changing the magnetic field strength and dynamically adjusting the viscosity and hardness of the magnetorheological fluid to achieve intelligent adjustment of the buffering performance.

[0058] Furthermore, an electromagnetic coil for adjusting the rheological properties of the magnetorheological fluid is provided inside the intelligent buffer module 11. The electromagnetic coil is connected to the energy storage device 18. The energy storage device 18 provides a stable current for the electromagnetic coil and dynamically adjusts the current magnitude according to requirements. The information of the collision target monitored by the sensor is transmitted to the control system. The control system calculates the optimal magnetic field strength through an algorithm according to the feedback signal and adjusts the current of the electromagnetic coil. The change in the current causes a change in the magnetic field strength, which in turn affects the arrangement state of the magnetic particles in the magnetorheological fluid. In the absence of a magnetic field or a weak magnetic field, the magnetorheological fluid remains in a low-viscosity liquid state, and the buffer module has good flexibility and adaptability; under the action of a strong magnetic field, the magnetic particles quickly arrange into a chain-like structure, significantly increasing the viscosity and yield strength of the magnetorheological fluid, and the hardness of the buffer module also increases accordingly.

[0059] The offshore wave energy conversion and protection system of the present invention is applicable to various complex engineering scenarios such as ocean engineering, cross-sea bridge engineering, and coastal areas. In ocean engineering and coastal areas, the present invention can efficiently utilize wave energy for power generation, providing stable renewable energy for offshore facilities, monitoring equipment, and coastal infrastructure, reducing dependence on traditional energy, and lowering operating costs; in cross-sea bridge engineering, the intelligent buffer module can effectively absorb the energy of ship collisions, protect the bridge structure from impact damage, improve the safety and durability of the bridge, and reduce maintenance costs.
