Description

Technical Field

[0001] The present application relates to the field of regulatory technology, and in particular to a wind-wave fusion power generation platform. Background Art

[0002] The development of offshore renewable energy is the key to solving global crises such as climate warming and environmental pollution. Since 2001, the annual increase in offshore wind power has been on the rise, especially from 2013 to 2023, the new installed capacity of offshore wind turbines has developed rapidly, and offshore wind power has become an important development direction of the wind energy industry. my country has abundant marine wind energy resources, and the development of offshore wind energy resources can effectively improve my country's energy structure. By the end of 2021, my country's cumulative offshore wind power installed capacity accounted for the largest proportion in the world. In the deep sea, floating foundations have more advantages than fixed foundations, such as richer wind resources and less noise pollution. Therefore, the development and utilization of offshore wind and wave energy resources will become the key to solving the current technical problems and promoting the development and utilization of deep sea resources in my country.

[0003] At present, the development of offshore wind and wave energy faces some key challenges. First, as the development of shallow-water wind power in my country gradually approaches saturation, some planned offshore wind farms are already located in deep waters of more than 50 meters, and traditional fixed wind turbines cannot adapt to this deep-water environment. Therefore, floating wind power has become an inevitable trend in the development of offshore wind power in the future. However, when developing wind energy in deep-sea areas, under the interaction of wind and waves, the platform will resonate or swing excessively when subjected to wind and wave forces of different directions and frequencies. On the other hand, wind and wave energy are inherently fluctuating, and the available energy has a high degree of uncertainty in time and intensity, which will affect the continuity and efficiency of power generation. Secondly, since the platform is far away from the coast, special equipment and relevant technicians are required for repair and maintenance, which will incur corresponding operation and maintenance costs.

[0004] Therefore, it is urgent to provide a new solution to solve the technical problems of instability, high wave energy development cost and low wave energy capture efficiency of existing floating wind turbine platforms. Summary of the invention

[0005] In view of this, the purpose of this application is to provide a wind-wave fusion power generation platform to solve the technical problems of instability, high wave energy development cost and low wave energy capture efficiency of existing floating wind turbine platforms.

[0006] In order to achieve the above technical objectives, the present application provides a wind-wave fusion power generation platform, including a wind power generation device, a floating foundation, an oscillating water column wave energy device, and a pendulum plate wave energy device;

[0007] The floating foundation is connected to a dynamic cable device;

[0008] The wind power generation device is installed on the floating foundation;

[0009] The oscillating water column wave energy devices are in multiple numbers and are distributed around the circumference of the floating foundation and are flexibly connected to the floating foundation;

[0010] There are multiple pendulum-type wave energy devices, which are arranged one by one below the oscillating water column type wave energy device and are flexibly connected to the oscillating water column type wave energy device.

[0012] Further, the floating foundation includes a platform foundation and a plurality of hinged components;

[0013] The plurality of hinge assemblies are fixed to the outer peripheral surface of the platform foundation and are distributed around the circumference of the platform foundation;

[0014] Each of the hinged assemblies comprises at least one first universal joint;

[0015] Each of the oscillating water column wave energy devices is correspondingly connected to the first universal joint of one of the hinged components;

[0016] The wind power generation device fixes the top of the platform foundation.

[0017] Further, the oscillating water column type wave energy device comprises a hydraulic connecting rod, an oscillating water column body and a turbine generator;

[0018] The turbine generator is installed on the top of the oscillating water column body;

[0019] The pendulum-plate wave energy device is connected to the bottom of the oscillating water column body;

[0020] One end of the hydraulic connecting rod is connected to the outer peripheral surface of the oscillating water column body, and the other end is connected to the first universal joint.

[0021] Further, each of the hinged assemblies comprises two first universal hinges;

[0022] The two first universal joints are spaced apart in an upper and lower direction;

[0023] Each of the oscillating water column wave energy devices comprises two hydraulic connecting rods;

[0024] The two hydraulic connecting rods are spaced apart from each other, and the other ends of the two hydraulic connecting rods are connected to the two first universal joints in a one-to-one correspondence.

[0025] Further, the swing plate type wave energy device comprises a rotating rod, a second universal joint and a swing plate device body;

[0026] The rotating rod is installed at the bottom of the oscillating water column type wave energy device;

[0027] The second universal joint is connected to the rotating rod;

[0028] The swing plate device body is connected to the second universal joint.

[0029] Furthermore, the wind power generation device comprises a plurality of wind turbine blades, a wind turbine nacelle and a wind turbine tower;

[0030] The wind turbine tower is fixedly installed on the top of the floating foundation;

[0031] A plurality of fan blades are installed in a circular array on the fan nacelle;

[0032] The wind turbine nacelle is fixed to the top of the wind turbine tower.

[0033] Furthermore, the number of the fan blades is three.

[0034] Further, the dynamic cable device includes a mooring cable device and a ballast unit;

[0035] The mooring cable device is connected to the outer peripheral surface of the platform foundation;

[0036] The ballast unit is connected to the bottom of the platform foundation.

[0037] Furthermore, there are three oscillating water column wave energy devices, which are evenly distributed around the circumference of the floating foundation.

[0038] It can be seen from the above technical solutions that the wind-wave fusion power generation platform designed in this application has the following beneficial effects:

[0039] 1. The floating foundation and the oscillating water column wave energy device are designed to be connected flexibly, making the oscillating water column wave energy device modular, easy to install, disassemble and replace at sea, and reducing the difficulty and cost of operation and maintenance; the floating foundation can also serve as the base of other functional modules (such as wind power generation devices) at the same time, and the oscillating water column wave energy device can be integrated into the multi-energy complementary system through flexible connection.

[0040] 2. The flexible connection design can make the oscillating water column wave energy device adapt to waves of different directions and frequencies, and achieve more efficient wave energy capture by freely moving or adjusting angles. It can reduce the rigid coupling between the floating foundation and the oscillating water column wave energy device, thereby reducing the interference of the floating foundation movement on the air column vibration inside the oscillating water column body of the oscillating water column wave energy device, ensuring a more stable energy conversion process.

[0041] 3. The flexible connection design enables the oscillating water column wave energy device to maintain efficient operation under large wave heights or complex wave conditions, thus expanding its scope of application. Secondly, multiple oscillating water column wave energy devices are deployed in an array to form a large-scale wave energy field with the floating foundation, thus improving economic efficiency.

The co-structured wave energy device consisting of an oscillating water column wave energy device and a pendulum plate wave energy device is flexibly connected to a floating foundation and is matched with a wind power generation device, which comprehensively utilizes two renewable energy sources, wind and waves, to achieve multi-level and diversified development of offshore renewable energy, realize the complementarity of wind and wave energy resources, and effectively improve the utilization rate of renewable resources in the installation sea area.

[0043] 5. The oscillating water column wave energy device and the pendulum plate wave energy device adopt a common structure to achieve multi-layer energy capture. The oscillating water column wave energy device mainly uses the pressure changes of waves near the water surface to drive the air column to generate energy, while the pendulum plate wave energy device mainly captures the energy generated by the horizontal and vertical movement of underwater waves. By combining the two, the surface and middle and lower layer energy of the waves can be captured at the same time, significantly improving the energy conversion capacity of a single system.

[0044] 6. The pendulum-type wave energy device is connected to the oscillating water column wave energy device in a flexible connection manner, which can reduce the impact of waves on the oscillating water column wave energy device and avoid damage to the equipment due to severe sea conditions. The flexible connection design allows the oscillating water column wave energy device and the pendulum-type wave energy device to be designed and manufactured separately, which is convenient for transportation, installation and maintenance; secondly, the oscillating water column wave energy device mainly occupies surface space, while the pendulum-type wave energy device is located underwater, which can make full use of vertical water space resources, realize compact deployment of the marine energy system, and achieve the effect of efficient space utilization.

[0045] 7. The oscillating water column wave energy device and the pendulum plate wave energy device share the anchoring and floating foundation, which reduces the construction cost. The oscillating water column wave energy device and the pendulum plate wave energy device can be operated together on the floating foundation, and the maintenance work of the combined system can be carried out centrally, reducing the manpower and resource investment required for the operation of independent devices.

[0046] 8. The entire platform is compactly designed and occupies a relatively small area of ​​sea. Its deep-sea deployment reduces the impact on the nearshore ecosystem, while the flexible connection design reduces interference with underwater organisms.

[0047] 9. The floating + flexible connection design reduces the impact of wave impact on power output fluctuations and can provide a more stable energy supply. The water-swinging wave energy device and the pendulum-type wave energy device enable the entire platform to continuously capture energy under different wave conditions to meet long-term operation requirements.

[0066] The wind-wave fusion power generation platform designed in this application has the following beneficial effects:

[0067] 1.

[0070] 4.

[0071] 5. The oscillating water column wave energy device 30 and the swing plate wave energy device 40 adopt a common structure to achieve multi-layer energy capture. The oscillating water column wave energy device 30 mainly uses the pressure change of waves near the water surface to drive the air column 34 to generate energy, while the swing plate wave energy device 40 mainly captures the energy generated by the horizontal and vertical movement of underwater waves. By combining the two, the surface layer and the middle and lower layer energy of the wave can be captured at the same time, significantly improving the energy conversion capacity of a single system.

[0076] The above is an embodiment of a wind-wave fusion power generation platform provided in the embodiment of the present application. The following is an embodiment of a wind-wave fusion power generation platform provided in the embodiment of the present application. For details, please refer to Figures 1 to 7 .

[0077] Based on the solution of the above embodiment 1:

[0078] Furthermore, the floating foundation 14 is a straight cylindrical semi-submersible foundation; the straight cylindrical semi-submersible foundation is a deep-water floating structure, and its design relies on the downward shift of the center of gravity and the stability of the center of buoyancy, and has excellent anti-capsulation ability. In complex sea conditions, the stability of this floating foundation 14 can provide a more stable base for the connected oscillating water column wave energy device 30, reducing the overall impact of waves on the power generation platform.

[0079] Furthermore, if Figure 5 As shown, the design of the floating foundation 14 includes a platform foundation 20 and a plurality of hinged components.

[0080] A plurality of articulated assemblies are fixed to the outer peripheral surface of the platform foundation 20 and are distributed around the circumference of the platform foundation 20; each articulated assembly includes at least one first universal joint 21. A universal joint is an existing mechanical connection component that can realize flexible rotation connection in multiple directions. Its core principle is to allow the two connected components to rotate relative to each other within a certain angle range through a special structural design, and this rotation can occur on multiple planes at the same time. For example, it is similar to a human shoulder joint, which can move in different directions to adapt to various complex movement requirements. For this reason, the specific structure of the universal joint is not described in detail.

[0081] Each oscillating water column type wave energy device 30 is correspondingly connected to a first universal joint 21 of a hinge assembly to achieve a flexible connection.

[0082] The wind turbine generator 10 is fixed on the top of the platform foundation 20 .

[0083] Furthermore, if Figure 3 as well as Figure 4 As shown, the design of an oscillating water column wave energy device 30 (ie, an OWC wave energy device) includes a hydraulic connecting rod 31 , an oscillating water column body 33 , and a turbine generator 32 ; the turbine generator 32 is installed on the top of the oscillating water column body 33 .

[0084] The swing plate wave energy device 40 is connected to the bottom of the oscillating water column body 33; one end of the hydraulic connecting rod 31 is connected to the outer peripheral surface of the oscillating water column body 33, and the other end is connected to the first universal joint 21. The swing plate wave energy device 40 is connected to the oscillating water column body 33 to form a co-structured wave energy device, and then connected to the platform foundation 20 through the hydraulic connecting rod 31 and the first universal joint 21; the oscillating water column wave energy device 30 achieves a balance of overall flexibility and stability through the joint action of the hydraulic connecting rod 31 and the first universal joint 21, and can swing freely under the action of multi-directional waves, thereby more efficiently capturing wave energy.

[0085] like Figure 6As shown, the oscillating water column wave energy device 30 drives the oscillation of the air column 34 in the oscillating water column body 33 through the periodic movement of waves, thereby compressing the air in the cavity 35, and the air then drives the turbine generator 32 to generate electricity. For more specific structural components, reference can be made to existing OWC wave energy devices or they can be directly used, and no further description is given.

[0086] Furthermore, if Figure 5 As shown, each hinge assembly includes two first universal joints 21, and the two first universal joints 21 are spaced apart from each other.

[0087] like Figure 3 As shown, correspondingly, each water-swinging column type wave energy device includes two hydraulic connecting rods 31 , which are spaced apart from each other, and the other ends of each of the hydraulic connecting rods 31 are connected to the two first universal joints 21 in a one-to-one correspondence.

[0088] The design of double hydraulic connecting rods 31 makes the connection reliability between the water-swinging column type wave energy device and the platform foundation 20 better.

[0089] Furthermore, if Figure 4 As shown, the design of a swing plate type wave energy device 40 includes a rotating rod 42, a second universal joint 41 and a swing plate device body 43.

[0090] The rotating rod 42 is rotatably mounted on the bottom of the oscillating water column wave energy device 30 (specifically, rotatably mounted on the bottom of the oscillating water column body 33 ), the second universal joint 41 is connected to the rotating rod 42 , and the swing plate device body 43 is connected to the second universal joint 41 .

[0091] The swing plate device body 43 realizes overall swinging through the rotating rod 42 , and at the same time realizes flexible connection with the oscillating water column type wave energy device 30 through the cooperation of the second universal joint 41 and the rotating rod 42 .

[0092] The waves cause the periodic swing of the swing plate device body 43 through underwater movement, thereby converting the kinetic energy of the waves into mechanical energy, and further into electrical energy. The swing plate device body 43 is an existing swing type wave energy power generation module, and the more specific structural composition is not described in detail.

[0093] Furthermore, if Figure 2 As shown, the wind power generation device 10 is designed to include a plurality of wind turbine blades 11 , a wind turbine nacelle 12 and a wind turbine tower 13 .

[0094] The wind turbine tower 13 is fixedly mounted on the top of the floating foundation 14 , and a plurality of wind turbine blades 11 are mounted in a circular array on the wind turbine nacelle 12 . The wind turbine nacelle 12 is fixed to the top of the wind turbine tower 13 .

[0095] Under the action of wind, the plurality of fan blades 11 rotate, driving the generator set inside the fan nacelle 12 to generate electricity.

[0096] Furthermore, the number of the fan blades 11 may be three.

[0097] Furthermore, if Figure 3 As shown, a dynamic cable device 50 is designed to include a mooring cable device 51 and a ballast unit 52 .

[0098] The mooring cable device 51 is connected to the outer peripheral surface of the platform foundation 20; the mooring cable device 51 is an existing mooring cable module, which mainly includes a mooring cable, which is used to limit the movement of the floating foundation 14 to fix it in a specific position.

[0099] The ballast unit 52 is connected to the bottom of the platform foundation 20 and is used to adjust the center of gravity, draft, stability, buoyancy and other properties of the floating foundation 14. The specific composition is referred to the existing ballast module and will not be described in detail.

[0100] Furthermore, there are three oscillating water column wave energy devices 30, which are evenly distributed around the circumference of the floating foundation 14 (adjacent devices are spaced 120 degrees apart). Correspondingly, there are also three swing plate wave energy devices 40, and there are also three articulated assemblies.

[0101] The above is a detailed introduction to a wind-wave fusion power generation platform provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
