Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sea wave power generation equipment, and more particularly relates to a multifunctional offshore wave energy conversion and protection system and method. BACKGROUND

[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 a huge amount of energy, mainly in the form of vertical displacement (potential energy) and horizontal flow (kinetic energy) of water bodies. Wave energy conversion technology aims to capture these energies and convert them into electrical energy or other usable forms of energy.

[0003] With the intensification of global climate change and the increasing demand for marine resource development, traditional single-function marine engineering systems have been unable to meet the dual demands of carbon neutralization and sustainable development of coastal zones. In this context, the multifunctional offshore wave energy conversion system integrating wave power generation, coastal protection, and ecological restoration has become a research focus in the international marine engineering field.

[0004] Global energy transformation is accelerating, and the carbon neutralization target has made marine energy development inevitable. According to forecasts, wave energy will contribute at least 3.5% of global electricity demand by 2050, driving the integration of "sea wall-power generation" design to become a key technology path. At the same time, the threat of extreme weather is escalating, with the global average sea level rising at a rate of 4.8 mm / year in 2024, leading to 30% of coastal cities facing the risk of tidal disasters, and the damage rate of traditional breakwaters under extreme sea conditions exceeding 65%.

[0005] Currently, wave energy development faces many technical problems, which seriously restricts its large-scale commercial application. The mainstream oscillating water column (OWC) device has low energy conversion efficiency, with an average of only 18%-25%, and in 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, which is much lower than the 20 years of onshore wind power equipment. In extreme sea conditions, the adaptability of existing wave energy devices is poor, and when the wave height exceeds 10 meters, 80% of the devices will automatically shut down, causing an average annual power generation loss of 27%. At the same time, the reliability of the anchoring system is insufficient, and its failure is the main failure mode, accounting for 43% of the total number of accidents. The existing wave energy development technology needs to be broken through in terms of efficiency, durability and stability; traditional coastal protection projects also face many challenges, and the construction of concrete breakwaters has a significant negative impact on the ecological environment, leading to the degradation of 85% of intertidal zone biological habitats and serious damage to the balance of the marine ecosystem. In addition, artificial hard revetments change the nearshore flow field, further increasing the erosion rate of the local coast to 4 meters per year. From an economic point of view, the operation and maintenance cost of a single protection facility is extremely high, at $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 modes in terms of ecology and economy.

[0041] Example 1

[0042] As Figures 1-3 shown, the embodiment of the present application provides a multifunctional offshore wave energy conversion and protection system, comprising a plurality of conversion and protection devices 1, adjacent to the conversion and protection device 1 is hinged through flexible connecting member 2, the use of flexible connecting member 2 makes the conversion and protection device 1 can realize multidimensional relative motion, while maintaining the connectivity of the overall structure. Can effectively adapt to complex working conditions and dynamic changes in the environment, in the wave energy conversion and protection device, flexible connecting member 2 can be with the ups and downs of the wave expansion and angle adjustment, thereby improving the energy capture efficiency; through the hinged way of flexible connecting member 2, a plurality of conversion and protection device 1 can work together, form a dynamic system, can better capture and use external energy (such as wave energy), and by adjusting the length and angle of the telescopic rod, optimize the energy conversion process.

[0043] As Figures 4-6 shown, the conversion and protection device 1 includes two intelligent buffer modules 11 and transmission plate 12, each of the intelligent buffer module 11 top surface is provided with two first ball hinge connecting device 15, the bottom of the first ball hinge connecting device 15 is fixedly installed with connecting plate 151, the bottom of the connecting plate 151 is fixedly installed with sliding block 152; the top of the intelligent buffer module 11 is provided with a sliding groove 111 matched with the sliding block 152, allowing the first ball hinge connecting device 15 to slide relative to the intelligent buffer module 11; the bottom of each side of the transmission plate 12 is fixedly installed with two second ball hinge connecting device 16, the connecting plate 151 and the transmission plate 12 are provided with support transmission rod 13, the support transmission rod 13 and the connecting plate 111 are connected through the first ball hinge connecting device 15, the support transmission rod 13 and the transmission plate 12 are connected through the second ball hinge connecting device 16, under the action of sea waves, the two intelligent buffer modules 11 can adapt to different angles and positions, the support transmission rod 13 is connected with the connecting plate 151 and the transmission plate 12 through the first ball hinge connecting device 15 and the second ball hinge connecting device 16, respectively, forming an efficient force transmission path, not only optimizing the force transmission efficiency, but also ensuring the uniform distribution of force in 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 the shaft rod transmission assembly 14, the shaft rod transmission assembly 14 includes a connecting lug plate 141 arranged at the end of the intelligent buffer module 11 and parallel to each other, a through hole is arranged on each connecting lug plate 141, and the two intelligent buffer modules 11 are rotatably connected to each other through the second shaft rod 142 penetrating through the through holes on the connecting lug plates 141, so as to form a transmission structure with 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 the posture according to the direction and intensity of the wave, so as to better capture and convert wave energy.

[0045] Further, the middle of the transmission plate 12 is fixedly provided with two parallel lifting lugs 121, the lifting lugs 121 are provided with round holes, the transmission plate 12 is rotatably connected with the shaft rod transmission assembly 14 through the roller flywheel power generation device 17, the roller flywheel power generation device 17 is rotatably connected with the lifting lug 121 through the first shaft rod 122, and the roller flywheel power generation device 17 is rotatably connected with the connecting lug plate 141 through the second shaft rod 142.

[0046] Specifically, the transmission plate 12 is rotatably connected with the support transmission rod 13 and the roller flywheel power generation device 17, forming an elbow hinge transmission mechanism, which efficiently converts the small displacement of the input end into a large range of displacement of the output end. On the one hand, by using the geometric lever principle and the nonlinear amplification characteristic, exponential displacement growth is realized when approaching the "dead point", which is suitable for fast expansion or contraction scenarios. On the other hand, by optimizing the conversion of force and displacement, part of the input force is sacrificed to obtain greater output displacement, while the self-locking characteristic is possessed, which can maintain the position stable without continuous force at a certain angle. In addition, the transmission member also has space compactness, the folding structure and multi-degree-of-freedom integrated design not only significantly reduce the occupied space in the non-working state, but also realize complex trajectory output through multi-stage series or parallel connection, while keeping the overall structure simple and efficient.

[0047] Specifically, the intelligent buffer module 11 is subjected to the fluctuation and impact of the wave, and the intelligent buffer module 11 will produce up and down fluctuation and swinging movement, the transmission plate 12 moves relative to the intelligent buffer module 11 through the first ball hinge connecting device 15, the support transmission rod 13 and the second ball hinge connecting device 16, and the mechanical movement of the intelligent buffer module 11 is efficiently transmitted to the roller flywheel power generation device 17. The linkage action of these devices makes the roller flywheel power generation device 17 have large displacement movement, so as to drive the generator in the device to operate efficiently, and convert mechanical energy into electrical energy.

[0048] Further, a plurality of connecting rods 19 are arranged between the two support 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 channel for maintenance personnel to quickly reach the key parts of the equipment for maintenance and repair. This design reduces the preparation work of setting up temporary scaffolding and significantly shortens the maintenance time, taking into account the complex working environment at sea and being able to adapt to the displacement or deformation of the equipment that may occur during operation.

[0049] Further, as shown in Figure 5 the other end of the intelligent buffer module 11 is provided with a connecting column 112, and the flexible connecting member 2 between the two conversion and protection devices 1 is fixedly connected with the intelligent buffer module 11 through the connecting column 112.

[0050] Further, the flexible connecting member 2 includes but is not limited to a spring, rubber or cable structure. The flexible connecting member 2 (such as a spring, rubber or cable structure) can effectively absorb and buffer external impact force, reduce the impact of waves or other external forces on the conversion and protection device 1, thereby protecting the stability and safety of the equipment, and the flexible connecting member 2 can provide elastic support, allowing the device to freely stretch or deform within a certain range while maintaining the stability of the connection, can absorb energy, and can also reduce damage to the equipment caused by external 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 combines flywheel energy storage technology, roller low-friction transmission and inertia mass regulation. 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 quickly converts the mechanical energy into its own rotational kinetic energy and stores it. In terms of 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 assembly connected to it to operate. The power generation assembly uses the principle of electromagnetic induction, and the rapidly rotating coil in the magnetic field cuts the magnetic induction lines, thereby accurately converting the mechanical energy of the flywheel rotation into electrical energy. This electromagnetic conversion method has the characteristics of high efficiency and stability, and can maximize the conversion of kinetic energy stored in the flywheel into usable electrical energy, greatly improving energy utilization efficiency.

[0052] Further, the top of the transmission plate 12 is provided with an energy storage device 18, which is connected with the roller flywheel generator 17. During operation, the roller flywheel generator 17 converts mechanical energy into electrical energy through a specific electromagnetic induction principle, and the generated electrical energy is then transmitted and stored in the energy storage device 18 in a timely manner. 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, laser radar, camera, and ultrasonic sensor) of the intelligent buffer module 11, ensuring that they 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 timely and accurate buffer adjustment decisions. On the other hand, these electrical energies can also be used to power the lighting equipment on the bridge, ensuring the lighting needs of the bridge in the night or dimly lit environment, improving the safety and convenience of the bridge, and providing a clear view for passing vehicles and pedestrians.

[0053] Specifically, advanced energy storage media such as high-performance lithium-ion batteries or supercapacitors are used inside the energy storage device 18. These energy storage media have high energy density, fast charging and discharging capability, and long cycle life, which can effectively store the electrical energy generated by the roller flywheel generator 17 and release it quickly 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. The system automatically adjusts the charging and discharging process through built-in sensors and microprocessors to ensure the safe operation of the energy storage unit and optimize energy utilization efficiency. The energy storage device 18 also integrates an energy conversion module that can convert the electrical energy generated by the roller flywheel generator 17 into a suitable voltage and current form for storage. At the same time, this module is also responsible for converting the stored electrical energy into a form suitable for use by sensors in the intelligent buffer module 11 and bridge lighting equipment, ensuring the stability and compatibility of power supply.

[0054] Further, the intelligent buffer module 11 is internally provided with a plurality of sensors, including but not limited to radar, camera, ultrasonic sensor, force sensor, temperature sensor, and inclination sensor, for real-time monitoring of the position, speed and motion trajectory of surrounding obstacles, and for identifying potential collision targets such as ships; the radar sensor can monitor the position, speed and motion trajectory of distant obstacles in real time by emitting and receiving electromagnetic waves, and can provide early warning of potential collision targets and provide time for dynamic adjustment of the buffer module; the camera sensor captures image or video data through optical imaging, for target recognition and environmental monitoring, for automatic identification and classification of targets such as ships, and further improves the intelligent level of the system; the ultrasonic sensor detects the distance and speed of close-range obstacles by emitting and receiving ultrasonic waves, and is suitable for close-range monitoring, which can effectively supplement the blind area of the radar sensor; the force sensor is used to monitor the force acting on the buffer module, which can accurately measure the magnitude and direction of the collision force, and dynamically adjust 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 working temperature range; the inclination sensor is used to detect the inclination angle of the equipment to ensure its stability in complex environments.

[0055] Further, the intelligent buffer module 11 is made of damping material and has a honeycomb structure inside, which is filled with magnetorheological fluid. The combination of the excellent energy dissipation characteristics of damping material, the high strength and lightweight advantages of honeycomb structure, and the intelligent controllable rheological characteristics of magnetorheological fluid realizes dynamic adjustment of 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, thereby achieving controllability of damping force, so that the buffer module can be dynamically adjusted according to different working conditions, adapt to high impact load and complex dynamic environment. This integrated design not only improves the buffer performance, but also protects the bridge and other fixed structures.

[0056] Specifically, magnetorheological fluid is an intelligent material composed of small soft magnetic particles with high magnetic permeability and low magnetic hysteresis, and a non-magnetic liquid. In the absence of an external magnetic field, the magnetorheological fluid exhibits liquid flowability 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 quickly arrange into a chain structure, causing a significant change in the viscosity and yield strength of the magnetorheological fluid, changing from a liquid state to a solid-like state. This rapid and reversible rheological property enables the intelligent buffer module 11 to adjust its buffer performance in real time by adjusting the magnetic field strength according to the actual impact situation, achieving 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 sensors, and 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 buffer performance.

[0058] Furthermore, the intelligent buffer module 11 is equipped with an electromagnetic coil for adjusting the rheological properties of the magnetorheological fluid. The electromagnetic coil is connected to the energy storage device 18, which provides a stable current to the electromagnetic coil and dynamically adjusts the current magnitude as needed. The information of the collision target detected by the sensor is transmitted to the control system. Based on the feedback signal, the control system calculates the optimal magnetic field strength through an algorithm and adjusts the current of the electromagnetic coil. The change in current leads to a change in the magnetic field strength, which in turn affects the arrangement of magnetic particles in the magnetorheological fluid. Under no magnetic field or weak magnetic field, the magnetorheological fluid maintains 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 structure, which significantly increases the viscosity and yield strength of the magnetorheological fluid, and the hardness of the buffer module also increases accordingly.

[0059] This invention relates to a marine wave energy conversion and protection system, applicable to various complex engineering scenarios such as marine engineering, cross-sea bridge projects, and coastal areas. In marine engineering and coastal areas, this invention can efficiently utilize wave energy for power generation, providing a stable renewable energy source for marine facilities, monitoring equipment, and coastal infrastructure, reducing dependence on traditional energy sources and lowering operating costs. In cross-sea bridge projects, the intelligent buffer module can effectively absorb the energy of ship collisions, protecting the bridge structure from impact damage, improving the safety and durability of the bridge, and reducing maintenance costs.
