Therefore, the need to accelerate the development of ocean wave energy resources has emerged as the country and society need.

[0003] The power generation capacity of a wave power generation device is directly related to the frequency of the incident waves and the damping of the system. The optimal matching damping of the system changes with the change of the frequency of the incident waves. The wave height, wavelength and frequency of waves in the ocean are random, resulting in unstable and discontinuous wave energy. The efficiency of the traditional oscillating water column device is only 20%-30% due to air turbine losses; the float type device is difficult to integrate multi-directional wave energy due to the single transmission chain design, and the fixed anchoring system is prone to capsizing in extreme sea conditions; the counterweight adjustment relies on the mechanical counterweight block, and the response speed is slow.

Detailed implementation manners

[0021] Energy is an important material basis for the development of human society. However, the increasing depletion of traditional fossil energy and the serious environmental pollution caused by its use during the process have prompted the world to actively seek sustainable clean energy alternative solutions. The ocean occupies about 71% of the earth's surface area and contains huge energy. Among them, wave energy is an important part of ocean energy. Wave energy has the advantages of high energy density, wide distribution, renewable, clean and pollution-free, and is regarded as one of the most potential future energy sources. Developing and utilizing wave energy power generation technology is of great significance for alleviating the energy crisis, reducing greenhouse gas emissions, and promoting the diversification and sustainable development of the energy structure.

[0022] Wave energy is the mechanical energy generated by the wind acting on the sea surface, and its energy size is closely related to factors such as wave height, wavelength, and period. The basic principle of wave energy power generation is to convert the mechanical energy such as the kinetic energy and potential energy of waves into electrical energy through a specific device. Essentially, the wave energy power generation process is a multi-stage energy conversion process. First, the mechanical energy of the waves drives the mechanical components of the power generation device to move, then this movement is transmitted to the generator through the mechanical transmission device, and finally the generator converts the mechanical energy into electrical energy for output.

[0023] There are various forms of wave power generation technology. According to the installation form, it can be divided into fixed type and floating type; according to different working principles, it can be divided into oscillating body type, oscillating water column type, overtopping type, etc. Different types of wave energy power generation devices have differences in energy conversion methods and specific structures, but generally they all revolve around the core goal of efficiently capturing wave energy and achieving stable energy conversion.

[0024] Oscillating water column wave energy power generation device

[0025] The oscillating water column wave energy power generation device is a wave energy power generation technology that is currently widely used. Its basic structure includes an air chamber communicating with the sea and an air turbine - generator set installed on the top of the air chamber. When waves enter the air chamber, the air inside the air chamber is compressed and expanded, forming an oscillating air flow, and the air flow drives the air turbine to rotate, thereby driving the generator to generate electricity.

[0026] The advantages of the oscillating water column device are relatively simple structure, high reliability, and suitability for various marine environments; the disadvantages are relatively low energy conversion efficiency, relatively large volume of the device, and relatively large impact on the environment.

[0027] Pendulum wave energy power generation device

[0028] The pendulum wave energy power generation device mainly consists of a pendulum plate, a hinge, and a mechanical transmission system. The pendulum plate is installed on the shore or an offshore platform and is connected to the fixed structure through a hinge. When waves act on the pendulum plate, the pendulum plate makes a reciprocating swing around the hinge, and the swing energy of the pendulum plate is transmitted to the generator through the mechanical transmission system to achieve the conversion of mechanical energy into electrical energy.

[0029] The pendulum device has the advantages of compact structure and high power generation efficiency, but the manufacturing and maintenance costs are relatively high.

[0030] Buoy type wave power generation device

[0031] The buoy type wave power generation device utilizes the up and down floating of the buoy under the action of waves, and converts the kinetic energy of the buoy into electrical energy through a transmission mechanism. This device has a simple structure and is easy to maintain, but the power generation efficiency is greatly affected by the size, direction, and frequency of the waves.

[0032] Suspended device

[0033] The suspended device drives the generator to generate electricity through the up and down movement of a heavy object suspended in the water under the action of waves. This device is suitable for deep - sea areas and has the advantages of high power generation efficiency and small floor area, but the installation and maintenance are difficult.

[0034] Concentrating wave reservoir type wave energy power generation device

[0035] The technology of wave energy generation using a concentrating reservoir is to use a special wave concentrating device to concentrate wave energy, raise the sea water level, form a water level difference similar to that of a reservoir, and then convert the potential energy of the water level difference into electrical energy through a water turbine - generator set. Its principle is similar to that of traditional hydropower generation.

[0036] The advantage of the wave concentrating reservoir device is that it can achieve stable power output and is not affected by the intermittency of waves; the disadvantage is that the construction cost is high, the requirements for terrain conditions are harsh, and a suitable bay or coastal terrain is needed to build the wave concentrating reservoir.

[0037] Point absorber wave energy generation device

[0038] The point absorber wave energy generation device is usually a small floating device. It mainly absorbs and converts the energy of waves into electrical energy by the up and down movement of one or more floats under the action of waves. The advantage of the point absorber device is its high flexibility, which can be arranged in different sea areas according to needs and has less impact on the environment; the disadvantage is that the power generation of a single device is small, and usually multiple devices need to form an array to meet the power demand of a larger scale.

[0039] The research on wave energy generation technology can be traced back to the end of the 18th century. In 1799, the Girard father and son in France first proposed the idea of using wave energy and obtained the first wave energy patent. Since then, in the 19th century, there were successive patent applications for the utilization of wave energy, but most of these early designs remained at the theoretical and conceptual stage and could not be put into practical use due to technical limitations.

[0040] In the mid-20th century, with the progress of science and technology and the gradual increase in the demand for new energy, the research on wave energy generation technology began to enter the substantive stage. In 1947, the British built the world's first oscillating water column wave energy generation device for navigation lights. Although its power was small, this marked an important step for wave energy generation from theory to practice.

[0041] During this period, the principles and designs of various wave energy generation devices were proposed and experimental studies were carried out, including different types of devices such as pendulum type, oscillating water column type, and raft type. In 1974, Japan built the "Wam" wave energy generation ship, which was the largest wave energy generation device in the world at that time, with a total installed capacity of 125 kW. The successful operation of the "Wam" provided valuable experience for the development of wave energy generation technology.

[0042] In the 1980s and 1990s, wave energy power generation technology made some progress in technical performance and reliability, and some countries began to build small wave energy power generation demonstration power stations. For example, in 1985, Norway built an oscillating water column wave energy power station with an installed capacity of 500kW on Toft Island near Bergen, which was the world's first commercially operated wave energy power station. However, due to the immature technology and high power generation costs at the time, wave energy power generation technology still failed to achieve large-scale commercial application during this period.

[0043] Entering the 21st century, with the rapid development of related fields such as materials science, control technology, and power electronics technology, wave energy power generation technology has ushered in new development opportunities. Countries have continuously increased their investment in the research and development of wave energy power generation technology, and many new wave energy power generation devices and technical solutions have emerged. At the same time, a series of large-scale wave energy power generation demonstration projects have been carried out around the world, such as the Agucadura wave energy power plant in Portugal, which was put into operation in 2008 with an installed capacity of 2.25MW, making it the largest wave energy power plant in the world at that time.

[0044] In recent years, wave energy power generation technology has achieved remarkable results in improving energy conversion efficiency, reducing costs, and enhancing device reliability. Some wave energy power generation devices have been able to achieve stable connection with the power grid and provide clean electricity for coastal areas. Although wave energy power generation still accounts for a small proportion of the global energy structure, with the continuous advancement of technology and the continuous reduction of costs, its development prospects are very broad.

[0045] The research, development and application of wave energy power generation devices involve multiple key technical fields and also face many challenges.

[0046] Energy conversion efficiency

[0047] Energy conversion efficiency is one of the core indicators of wave power generation devices. At present, the energy conversion efficiency of wave power generation devices is generally low. How to improve the energy conversion efficiency is an important direction for the development of wave power generation technology.

[0048] In order to improve the efficiency of energy conversion, researchers are constantly exploring new energy conversion mechanisms and device structures. For example, more efficient energy capture mechanisms are adopted, transmission system and generator design are optimized, and advanced control algorithms are introduced. In addition, the working performance of the device is predicted and evaluated through virtual simulation and experimental verification to optimize the design and performance of the device.

[0049] Device reliability and durability

[0050] Wave energy power generation devices need to operate in harsh marine environments for a long time, so their reliability and durability are crucial. At present, there are still some problems with the reliability and durability of wave energy power generation devices, such as material corrosion, mechanical wear, electrical faults, etc.

[0051] To improve the reliability and durability of the device, researchers are constantly exploring new materials and manufacturing processes to enhance the corrosion resistance and anti-wear ability of the device. At the same time, strengthen the maintenance and upkeep of the device, regularly inspect and repair the device, and promptly detect and handle potential faults. In addition, by introducing intelligent control systems and remote monitoring technologies, real-time monitoring and fault warning of the device are realized, improving the reliability and stability of the device.

[0052] Cost Control and Economic Benefits

[0053] Cost control and economic benefits of wave energy power generation devices are one of the key factors restricting their commercial application. At present, the cost of wave energy power generation devices is still relatively high, resulting in poor economic benefits.

[0054] To reduce the cost of wave energy power generation devices, researchers are constantly exploring new materials and manufacturing processes to reduce the manufacturing cost of the device. At the same time, by optimizing the structure and performance of the device, the power generation efficiency and reliability of the device are improved, thereby reducing the operation cost and maintenance cost. In addition, strengthen policy support and capital investment, promote the research and development and application of wave energy power generation technology, and promote the rapid development of the wave energy power generation industry.

[0055] Environmental Impact and Sustainability

[0056] Wave energy power generation devices will have a certain impact on the marine environment during the development and operation process. For example, the deployment and operation of the device may interfere with the habitat and migration of marine organisms, generating noise and vibration, etc. Therefore, during the research and development and application of wave energy power generation technology, it is necessary to fully consider its impact on the environment and sustainability.

[0057] To reduce the impact on the marine environment, researchers are constantly exploring new device structures and materials to reduce the interference and damage to marine organisms. At the same time, strengthen environmental monitoring and assessment, and promptly detect and handle potential environmental problems. In addition, promote the coupling and integration of wave energy power generation technology with other renewable energy technologies to form a multi-energy complementary power generation system, improving the utilization efficiency and stability of renewable energy.

[0058] As a clean and renewable energy technology, wave energy power generation devices have broad application prospects and development trends.

[0059] Power Supply Systems for Remote Islands and Coastal Cities

[0060] Wave energy power generation devices can provide stable and reliable power supply for remote islands and coastal cities. These areas are usually far from the traditional power grid, and the power supply is difficult and unstable. By using wave energy power generation devices, clean and reliable power supply can be provided for these areas to meet their electricity demands for living and production.

[0061] Energy supply for offshore observation and monitoring platforms

[0062] Wave energy power generation devices can provide energy supply for offshore observation and monitoring platforms. These platforms usually need to carry out long-term and continuous observation and monitoring work, so they require stable and reliable energy supply. By using wave energy power generation devices, continuous and stable power supply can be provided for these platforms to ensure their normal operation and the accuracy of data collection.

[0063] Coupling and integration with other renewable energy technologies

[0064] Wave energy power generation technology can be coupled and integrated with other renewable energy technologies such as solar energy and wind energy to form a multi-energy complementary power generation system. This multi-energy complementary power generation system can improve the utilization efficiency and stability of renewable energy, reduce the dependence on traditional energy and environmental pollution.

[0065] Development of intelligent and remote monitoring technologies

[0066] With the continuous development of intelligent and remote monitoring technologies, the intelligent level of wave energy power generation devices will continue to improve. By introducing advanced sensors, Internet of Things technologies and data analysis algorithms, real-time monitoring, remote control and intelligent scheduling of wave energy power generation devices can be realized. This can not only improve the reliability and stability of the devices, but also optimize their operation efficiency and power generation performance, and reduce the operation and maintenance costs.

[0067] Promotion of large-scale and commercial applications

[0068] With the continuous progress of technology and the continuous reduction of costs, wave energy power generation devices will gradually achieve large-scale production and commercial applications. In the future, more wave energy power generation projects will be launched and operated globally, forming a certain scale of wave energy power generation industry. This will provide strong support and promotion for the further development and application of wave energy power generation technology.

[0069] Strengthening of policy support and capital investment

[0070] The government's support for renewable energy will continue to increase, including policy measures such as providing tax incentives, financial subsidies, and support for technology R & D. This will provide strong policy guarantees and financial support for the R & D and application of wave energy power generation technology. At the same time, with the continuous development and improvement of the capital market, more funds will be invested in the field of wave energy power generation, promoting the rapid development of the wave energy power generation industry.

[0071] Strengthening of international cooperation and exchanges

[0072] The development and application of wave energy power generation technology require cooperation and exchanges on a global scale. Countries will strengthen cooperation and exchanges in aspects such as wave energy power generation technology R & D, demonstration project construction, and market promotion, jointly promoting the innovation and development of wave energy power generation technology. This will help accelerate the commercialization process of wave energy power generation technology and promote the transformation of the global energy structure and sustainable development.

[0073] As a clean and renewable energy technology, wave energy power generation devices have broad application prospects and development potential. With the continuous progress of technology and the continuous reduction of costs, wave energy power generation devices will gradually achieve large-scale production and commercial application. In the future, wave energy power generation technology will play an important role in remote islands, coastal cities, offshore observation platforms and other fields, contributing to the transformation of the energy structure and sustainable development.

[0074] However, the development of wave energy power generation technology still faces some challenges and problems. For example, how to improve energy conversion efficiency, reduce operation and maintenance costs, and reduce the impact on the marine environment still requires further research and exploration. Therefore, we need to strengthen technology R & D and innovation, promoting the continuous progress and improvement of wave energy power generation technology. At the same time, the government and all sectors of society also need to increase support and investment in wave energy power generation technology, providing strong policy guarantees and financial support for its development.

[0075] Looking ahead, wave energy power generation technology will become an important part of the global energy structure transformation and sustainable development. We believe that with the joint efforts of all parties, wave energy power generation technology will continue to make new breakthroughs and progress, making greater contributions to the sustainable development of human society.

[0076] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0077] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] Referring to Figure 1 - Figure 2 As shown, this embodiment provides an ocean wave energy power generation device, including an anchoring mechanism. The anchoring mechanism includes an anchoring platform 1. The bottom of the anchoring platform 1 is provided with an anchoring part connected to the seabed. The top surface of the anchoring platform 1 is rotatably connected to a first connecting rod 2. The top surface of the first connecting rod 2 is slidably connected to a wave absorption mechanism. The wave absorption mechanism includes a first connecting column 3 slidably connected to the first connecting rod 2. A wave collection part is drivingly connected inside the first connecting column 3. The top surface of the first connecting column 3 is fixedly connected to a balance chamber 4. An electric quantity collection part is arranged inside the balance chamber 4. The electric quantity collection part is drivingly connected to the wave collection part. A balance mechanism is arranged outside the balance chamber 4.

[0079] The ocean wave energy power generation device is fixed to the seabed through the anchoring mechanism. The wave pushes the wave absorption mechanism to slide along the first connecting rod 2. The wave collection part inside the first connecting column 3 converts the wave kinetic energy into mechanical energy and generates electricity through the electric quantity collection part. The balance mechanism monitors the inclination angle of the platform and adjusts the balance chamber 4 to maintain the stability of the device. At the same time, the sensor inside the balance chamber 4 monitors the wave frequency in real time, combines with the AI algorithm to predict the wave pattern, and maximizes the energy absorption by adjusting the mass of the balance chamber 4 to make the resonance frequency of the device match the wave.

[0080] In a further optimized solution, the wave collection part includes second connecting rods 5 symmetrically and rotatably connected to the first connecting column 3. A plurality of flow guiding plates 6 are circumferentially and equally spaced and fixedly connected to the side of the second connecting rod 5 away from the first connecting column 3. A first cavity 7 is arranged inside the first connecting column 3. One end of the second connecting rod 5 close to the first connecting column 3 extends into the first cavity 7 and is fixedly connected to a first bevel gear 8. A second bevel gear 9 is drivingly connected between the two first bevel gears 8. The second bevel gear 9 is drivingly connected to the electric quantity collection part.

[0081] The wave impacts the flow guiding plate 6, driving the second connecting rod 5 to rotate. Then, through the transmission of the first bevel gear 8 and the second bevel gear 9, the mechanical energy is transmitted to the electric quantity collection part. The design of the flow guiding plate 6 increases the contact area between the wave and the device, and the bevel gear set realizes two-way kinetic energy integration, improving the energy collection efficiency.

[0082] In a further optimized solution, the electric quantity collection part includes a third connecting rod 10 fixedly connected to the second bevel gear 9. One end of the third connecting rod 10 away from the second bevel gear 9 extends into the balance chamber 4 and is fixedly connected to a first magnetic gear 11. A generator 12 is fixedly connected to the top inner surface of the balance chamber 4. A second magnetic gear 13 is fixedly connected to the output shaft of the generator 12. The first magnetic gear 11 is adapted to the second magnetic gear 13.

[0083] The third connecting rod 10 drives the first magnetic gear 11 to rotate, and drives the second magnetic gear 13 and the generator 12 to generate electricity through magnetic coupling, avoiding mechanical contact friction. The magnetic gear transmission reduces energy loss and maintenance frequency. The combination of the magnetic gear and the generator 12 realizes efficient conversion of mechanical energy to electrical energy. Through the multi-stage transmission chain of the guide plate 6-bevel gear-magnetic gear, efficient conversion of wave energy → mechanical energy → electrical energy is realized.

[0084] A further optimized solution is that a first groove 14 is provided at the bottom of the first connecting column 3, the first connecting rod 2 is slidably connected in the first groove 14, a first slide groove 15 is symmetrically provided in the first groove 14, sliders 16 are symmetrically fixed at both ends of the first connecting rod 2, the slider 16 is slidably connected to the first slide groove 15 adjacent to it, and a spring 17 is fixed between the bottom surface of the slider 16 and the first slide groove 15.

[0085] The first connecting column 3 slides along the first sliding groove 15 through the slider 16, and the spring 17 buffers the wave impact force and suppresses resonance. The design of the spring 17 enhances the stability and durability of the device, reduces the peak stress, further reduces the impact of waves on the device, and prolongs the life of the device.

[0086] A further optimized solution is that the balancing mechanism includes a level sensor 18 fixedly connected to the top surface of the balancing chamber 4, a water tank 19 is provided on the bottom surface of the balancing chamber 4, a plurality of balancing cylinders 20 are fixedly connected at equal intervals on the outer circumference of the balancing chamber 4, the water tank 19 is connected to the balancing cylinder 20 via a first connecting pipe 21, and a first valve 22 is provided in the first connecting pipe 21.

[0087] The horizontal sensor 18 detects the tilt angle of the platform and controls the first valve 22 to adjust the water distribution between the balance cylinder 20 and the water tank 19, dynamically adjusting the center of gravity. Real-time counterweight adjustment makes the platform roll angle ≤5° to ensure power generation stability.

[0088] According to a further optimization scheme, the balancing cylinder 20 is connected to the bottom of the balancing chamber 4 with a second connecting pipe 23 . The second connecting pipe 23 is located below the first connecting pipe 21 . The second connecting pipe 23 is connected to the water tank 19 . A second valve 24 is provided in the second connecting pipe 23 .

[0089] The second connecting pipe 23 quickly drains water when it is extremely tilted, and controls the return water tank 19 through the second valve 24 to achieve rapid center of gravity reset. The dual-pipe system shortens the balance response time, thereby increasing its survival rate under typhoon conditions.

[0090] According to a further optimization scheme, the anchoring part includes an anchoring seat 25 fixed to the seabed, one end of a chain 26 is hinged to the anchoring seat 25, a plurality of ball joints 27 are fixed to the bottom surface of the anchoring platform 1, and the other end of the chain 26 is transmission-connected to the ball joint 27.

[0091] The anchoring seat 25 is flexibly connected to the chain 26 through a spherical hinge 27, allowing the platform to swing in multiple directions to disperse the wave impact force. The flexible anchoring system reduces the risk of anchor chain breakage and adapts to complex seabed topography.

[0092] In a further optimized solution, superhydrophobic coatings are respectively sprayed on the outer surfaces of the anchoring platform 1, the first connecting rod 2, and the first connecting column 3.

[0093] The superhydrophobic coating reduces the adhesion and corrosion of seawater to the surface of the device, extending the service life of the device. At the same time, the superhydrophobic coating repels water molecules through micro-nano structures, reducing the attachment of marine organisms.

[0094] In a further optimized solution, the balance bin 4 is made of carbon fiber reinforced polymer. The carbon fiber reinforced polymer balance bin 4 reduces the inertial resistance through lightweight design.

[0095] In a further optimized solution, embedded ultrasonic generators are respectively provided inside the anchoring platform 1, the first connecting rod 2, and the first connecting column 3. The embedded ultrasonic generators release high-frequency pulses to destroy the attachment mechanism of marine organisms and reduce the impact of biological fouling on the power generation efficiency.

[0096] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0097] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
