Description

Technical Field

[0001] This invention relates to the field of integrated development technology of offshore renewable energy, and in particular to an integrated device for a floating wind turbine-oscillating float wave energy device. Background Technology

[0002] In recent years, floating offshore wind turbine (FOWT) technology has developed rapidly due to engineering improvements, gradually propelling the industry towards maturity. However, several major issues still constrain the large-scale development of FOWT. Although FOWT has development potential in deep water areas, it is still in its early stages of development, with high levelized cost of energy (LCOE). Furthermore, providing a stable operating environment for FOWT is also a significant challenge. Meanwhile, to further increase the overall development of marine clean energy, the core focus should be on researching the integrated development of multiple marine energy sources to achieve large-scale utilization of marine energy.

[0003] To promote the large-scale utilization of ocean energy, and considering that wave energy, as a high-energy-density and highly predictable renewable energy source, is abundant but its independent development costs are too high, it is worth noting that most wind-rich sea areas also contain abundant wave energy resources. This creates conditions for building an integrated "wind-wave" complementary platform. By integrating the Wave Energy Converter (WEC) into the foundation of a floating wind turbine, near-surface space can be effectively utilized, energy output can be increased, and the cost of infrastructure sharing can be reduced.

[0004] Among various types of wind turbine (WEC) systems, the oscillating buoy (OB) unit is widely considered the best integration choice for floating wind turbine platforms due to its simple structure, high energy extraction efficiency, and high reliability. Its working principle utilizes the reciprocating motion of a buoy driven by waves to convert mechanical energy into electrical energy through a hydraulic or mechanical transmission system. Crucially, the target height for wind energy harvesting from floating wind turbines typically exceeds 100 meters, indicating that the space near the sea surface is not fully utilized. Furthermore, during periods of low wind speed, wind power generation is insufficient. Therefore, integrating the OB unit into the wave zone of the floating foundation allows for complementary development of wind and waves in both time and space.

[0005] Numerous academic studies and engineering case studies have demonstrated that the application of heave plates can significantly suppress the heave motion response of floating platforms. With proper design, it can also optimize the motion of other degrees of freedom of the floating platform. The single-column (SPAR) offshore floating oil platform and the OC4 offshore floating wind turbine are two of the most typical application cases.

[0006] CN111412102A discloses a wind-wave energy integrated power generation platform based on a semi-submersible floating wind turbine and an oscillating buoy. This innovatively integrates the oscillating buoy wave energy conversion device and the floating wind turbine, demonstrating a significant increase in power output compared to a single oscillating buoy wave energy conversion device, achieving integrated wind-wave energy development. CN117588369A discloses a wind-wave integrated power generation platform and an anti-overturning rapid balancing system, utilizing multiple oscillating buoy wave energy conversion devices to improve the stability of the floating platform and solve the problem of excessive overturning in wind and wave environments. However, under extreme sea conditions, these inventions cannot reduce the load on the integrated device and may even increase stress, hindering motion response. Furthermore, components subjected to wave action are prone to damage, making it difficult to guarantee their durability.

[0007] Research at the forefront of offshore energy development and innovative inventions reveal that how to efficiently integrate or develop wind and waves, optimize the platform stability of floating wind turbines, and improve the durability and survivability of floating wind turbines are urgent problems to be solved.

[0038] The purpose of this invention is to provide an integrated device for a floating wind turbine-oscillating buoy wave energy system, to solve the problems existing in the prior art, enabling the complementary utilization of wind and wave energy in mid- and offshore areas, reducing the wave load on the floating wind turbine, improving its overall stability, and enhancing its survivability and durability. The invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] An integrated device for a floating wind turbine-oscillating buoy wave energy conversion device, comprising: a wind turbine unit 1, a floating foundation 2, an oscillating buoy wave energy conversion device 3, a control terminal, and a power transmission system;

[0040] Preferably, it also includes a multi-layer sway plate device 4.

[0041] Preferably, the integrated device of floating wind turbine-oscillating buoy wave energy conversion device is moored in the open sea. The wind turbine device 1 works under the action of sea wind, continuously converting wind energy into electrical energy. At the same time, the oscillating buoy wave energy conversion device 3 also works under the action of waves, continuously converting wave energy into electrical energy. Then, together with the electrical energy generated by the wind turbine device 1, they are collected into the matching power transmission system. In this way, the energy utilization efficiency can be greatly improved and the cost per kilowatt-hour can be reduced through a single system.

[0042] Preferably, in this invention, the wind turbine device 1 includes: a tower 13, a generator nacelle 12 located at the top of the tower, wind turbine blades 11, a wind speed monitoring sensor 15 and a laser wavefront displacement sensor 14 disposed on the side of the tower 13.

[0043] With this, the wind speed monitoring sensor 15 and the laser wavefront displacement sensor 14 on the side wall of the tower 13 collect wind and wave information of the current sea state, and at the same time determine the current sea state. The control terminal can lock or unlock the float 32 and adjust the raising and lowering of the energy-concentrating arc plate 31 to maximize energy conversion efficiency and ensure structural safety.

[0044] Preferably, in this invention, the floating foundation 2 comprises: side columns 21, side column bottom floating hoppers 22, side connecting floating hoppers 23, upper horizontal bracing 25, upper diagonal bracing 26, and lower horizontal bracing 27;

[0045] With this, three side columns 21, three side column bottom floating tanks 22, and three side connecting floating tanks 23 are set up to form an overall foundation frame. Multiple supporting connecting columns 24, upper horizontal braces 25, upper diagonal braces 26, and lower horizontal braces 27 are connected to each other to ensure the rigidity, buoyancy, and stability of the floating foundation.

[0046] With this in mind, the wave-affected portion of each side column 21 was redesigned using a lattice structure. Instead of using a single, continuous connection, multiple supporting columns 24 were used to connect the upper and lower parts, reducing the area of ​​the foundation of the entire integrated device exposed to waves. Waves can effectively pass through the lattice design section, thereby reducing the load on the foundation caused by waves.

[0047] Preferably, in this invention, the oscillating float wave energy conversion device 3 comprises: a wave energy generation mechanism, a reflection energy focusing mechanism, and a float survival protection mechanism, all of which are integrated into each side column 21.

[0048] Preferably, in this invention, the wave energy generation mechanism comprises: a float 32, a rigid connecting rod 33, and a direct-drive power generation mechanism 36;

[0049] With this, one float 32 is set in each side column 21, which is connected to a rigid connecting rod 33. The lower part of the rigid connecting rod 33 passes through the groove reserved in the center of the lower side column and swings within the lattice structure. Wave energy is converted by the direct-drive power generation mechanism 36 within it.

[0050] Preferably, in this invention, the reflective energy-concentrating mechanism comprises: an energy-concentrating arc-shaped plate 31 and an arc-shaped plate control track 34, both disposed on the side wall of the upper side column;

[0051] With this, each reflective energy-concentrating mechanism is equipped with four energy-concentrating arc-shaped plates 31, each approximately 90 degrees. Under the control of the control terminal, the connecting gear set 37 is driven by a motor located inside the side column 21 to lower or raise the arc-shaped plate control track 34. In surviving sea conditions, raising all the energy-concentrating arc-shaped plates allows waves to effectively pass through the lattice-shaped design section, reducing the wave action area and thus reducing the load. In working sea conditions, lowering the corresponding two energy-concentrating arc-shaped plates 31 can reflect waves back to the float 32, improving wave energy conversion efficiency.

[0052] Preferably, in this invention, the float survival protection mechanism comprises: a float protection chamber 35 and a float locking chuck 38;

[0053] With this, the float shelter 35 is formed in the recessed center of the top of the lower side pillar, designed to just accommodate the float 32. The float locking chuck 38 is set to be embedded in the lower part of the float shelter 35 and can be controlled by the control terminal to clamp the rigid connecting rod 33 to lock the float 32, or release the rigid connecting rod 33 to unlock the float 32. In the survival sea state, locking the float 32 in the float shelter 35 can reduce the wave force on the float 32, prevent the float 32 from being damaged due to excessive movement, and improve its durability. In the working sea state, the float 32 is unlocked, and the float 32 floats up due to its own buoyancy and continues to generate electricity by heave.

[0054] Preferably, in this invention, the multi-layer sway plate device 4 comprises: a multi-layer sway plate 42 and a sway plate connecting column 43;

[0055] With this, the lower extension tower 41 of the wind turbine is the downward extension of the tower through the floating foundation, and multiple heave plates 42 are connected by multiple heave plate connecting columns 43; this design can significantly improve the heave stiffness and pitch stiffness of the overall system, reduce the heave and pitch motion response of the overall system under wave action, and improve the stability of the overall system.

[0056] Even better, the multi-layer heave plate device 4 can significantly reduce the heave motion response of the overall system, increase the relative motion between the float 32 and the overall system, and improve the wave energy conversion efficiency.

[0057] Preferably, in this invention, the control terminal is integrated inside the tower of the wind turbine unit and is electrically connected to various system controllers such as the float locking chuck and the energy-concentrating arc plate controller.

[0058] For easier understanding, please refer to Figures 1-6 .

[0059] Fan unit 1 Figure 2 As shown, it includes wind turbine blades 11, generator nacelle 12, tower 13, laser wavefront displacement sensor 14, and wind speed monitoring sensor 15;

[0060] Specifically, the wind turbine blades 11, generator nacelle 12, and tower 13 constitute a wind power generation unit; the laser wavefront displacement sensor 14 and the wind speed monitoring sensor 15 collect wind and wave information of the current sea state, and at the same time determine the current sea state. The control terminal can lock or unlock the float and adjust the raising or lowering of the energy-concentrating arc plate to maximize energy conversion efficiency and ensure structural safety.

[0061] Floating foundations, such as Figure 3 As shown, it includes side column 21, side column bottom floating tank 22, side connecting floating tank 23, supporting connecting column 24, upper horizontal brace 25, upper diagonal brace 26, and lower horizontal brace 27;

[0062] Specifically, the floating foundation 2 is equipped with 3 side columns 21, 3 side column bottom floating tanks 22, and 3 side connecting floating tanks 23 to form an overall foundation frame. Multiple supporting connecting columns 24, upper horizontal braces 25, upper diagonal braces 26, and lower horizontal braces 27 are interconnected to ensure the rigidity, buoyancy, and stability of the foundation.

[0063] Specifically, each side column 21 is designed as two parts, upper and lower, connected by three supporting columns 24 in the middle. This forms a lattice structure while ensuring overall strength and load-bearing capacity. This reduces the area of ​​the floating foundation 2 exposed to waves, allowing waves to effectively pass through the lattice structure, reducing the load on the overall system and improving overall stability.

[0064] Oscillating float wave energy conversion device such as Figure 4 and Figure 5 As shown, the wave energy generation mechanism, the energy reflection and focusing mechanism, and the float survival cover mechanism are all integrated into the side column 21;

[0065] Specifically, the wave energy generation mechanism includes a float 32, a rigid connecting rod 33, and a direct-drive power generation mechanism 36. The float 32 is connected to the rigid connecting rod 33, and the direct-drive power generation mechanism 36 is integrated on the upper part of the side column 21. Under the action of waves, the float 32 drives the rigid connecting rod 33 to perform a swaying motion. The coil on the upper part of the rigid connecting rod 33 cuts magnetic field lines in the direct-drive power generation mechanism 36 to generate electricity, thereby realizing wave energy conversion.

[0066] Specifically, the energy-concentrating reflection mechanism includes an energy-concentrating arc plate 31, an arc plate control track 34, and a gear set 37. Each side column 21 has four energy-concentrating arc plates on its side wall, each approximately 90 degrees. Under the control of the control terminal, the gear set 37 is driven by a motor located inside the side column 21 to lower or raise the plate on the arc plate control track 34. In surviving sea conditions, raising all the energy-concentrating arc plates 31 allows waves to effectively pass through the lattice structure, reducing the wave impact area, reducing load, and enhancing stability. In working sea conditions, lowering the two energy-concentrating arc plates 31 corresponding to the wave direction information reflects the waves back to the float 32, improving wave energy conversion efficiency.

[0067] Specifically, the float survival protection mechanism includes a float protection chamber 35 and a float locking chuck 38. The float protection chamber is formed in the recessed center of the top of the lower side pillar, designed to just accommodate the float 32. The float locking chuck 38 is embedded in the lower part of the float protection chamber 35 and can be controlled by a control terminal to clamp the rigid connecting rod 33 to lock the float, or release the rigid connecting rod 33 to unlock the float 32. In the survival sea state, when the float 32 and the rigid connecting rod 33 reach the warning value during a heave motion, and the float 32 just moves to the lowest point and is completely inside the float protection chamber 35, the float locking chuck 38 clamps the rigid connecting rod, locking the float in the float protection chamber 35, reducing the wave force on the float, preventing the float from being damaged due to excessive movement, and improving its durability. When returning to the working sea state, the float locking chuck 38 releases the rigid connecting rod, and the float rises due to its own buoyancy and continues to generate electricity.

[0068] Multi-layer slab structure such as Figure 6 As shown, it includes a lower extension tower 41 of the wind turbine, a multi-layer sway plate 42, and a sway plate connecting column 43;

[0069] Specifically, the lower extension tower 41 of the wind turbine is the downward extension of the tower 13 through the floating foundation 2, and multiple sway plates 42 are connected by multiple sway plate connecting columns 43. This design can significantly improve the sway stiffness and pitch stiffness of the overall system, reduce the relevant motion response of the overall system under wave action, and improve the stability of the overall system.

[0070] In particular, the multi-layer heave plate device 4 can reduce the heave motion response of the overall system, increase the relative motion between the float 32 and the overall system, and improve the wave energy conversion efficiency.

[0071] The control terminal is integrated inside the tower 13 of the wind turbine unit 1 and is electrically connected to various system controllers such as the float locking chuck 38 and the energy-concentrating arc plate controller.

[0072] For any of the above-mentioned parts involving electrical signal control, corrosion prevention, or other stringent requirements, strict sealing methods must be employed to protect the safety and durability of the overall integrated device.
