Description

Technical Field

[0001] This application relates to the field of wind power equipment technology, and in particular to an offshore wind power foundation and an offshore wind turbine generator set. Background Technology

[0002] Wind energy, as a clean and renewable energy source, is being widely used globally. Offshore wind turbines are one of the important ways to utilize wind energy, and they typically include offshore wind power foundations.

[0003] Unlike onshore wind turbine foundations, offshore wind turbine foundations are not only affected by wind loads, but also by environmental loads such as waves, ocean currents, and sea ice. This results in offshore wind turbine foundations bearing greater loads and are prone to motion response, which in turn leads to a decrease in the stability of offshore wind turbine foundations.

[0004] Therefore, a new device is urgently needed to solve the above problems. Utility Model Content

[0005] This application provides an offshore wind power foundation and an offshore wind turbine generator set to solve the problem that current offshore wind power foundations are prone to motion response, which leads to a decrease in the stability of the offshore wind power foundation.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] On one hand, this application provides an offshore wind power foundation, including: a monopile foundation; and damping units disposed on the monopile foundation. Multiple sets of damping units are arranged at intervals along the height direction of the monopile foundation. Each set of damping units includes multiple damping components, which are distributed circumferentially around the monopile foundation. Each damping component includes a driving member and a damping element rotatably connected to the driving member. The end of the driving member away from the damping element is connected to the monopile foundation. The damping element has a damping surface on its side facing the outer circumferential surface of the monopile foundation. The damping surface can be set at a predetermined angle relative to the height direction of the monopile foundation. The driving member is used to drive the damping element to rotate relative to the monopile foundation, so that the predetermined angle is adjustable.

[0008] In one possible implementation, the offshore wind power foundation provided in this application has a predetermined tilt angle greater than or equal to 0° and less than or equal to 60°.

[0009] In one possible implementation, the offshore wind power foundation provided in this application has, along the circumferential direction, a spacing angle between two adjacent damping components in each group of damping units that is less than or equal to 60°; and / or, along the height direction, the orthographic projections of each damping component in at least two groups of damping units are staggered from each other.

[0010] In one possible implementation, the offshore wind power foundation provided in this application has a spacing of less than or equal to 0.5m between any two adjacent damping units in each set of damping units along the height direction.

[0011] In one possible implementation, the offshore wind power foundation provided in this application has, along the height direction, at least some of the damping elements in each group of damping units have the same thickness; and in each group of damping units, at least some of the damping elements have a gradually decreasing thickness.

[0012] In one possible implementation, the offshore wind power foundation provided in this application includes a damping plate as the damping element, and the damping plate includes at least one of a flat damping plate, a fan-shaped damping plate, and an arc-shaped damping plate.

[0013] In one possible implementation, the offshore wind power foundation provided in this application includes a damping component comprising a first connecting portion and a second connecting portion; and a driving component comprising a first driving portion and a second driving portion, wherein the first driving portion is rotatably connected to the first connecting portion, and the second driving portion is rotatably connected to the second connecting portion, and at least one of the first driving portion and the second driving portion is used to drive the damping component to rotate.

[0014] In one possible implementation, the offshore wind power foundation provided in this application includes at least one of the first drive unit and the second drive unit, which includes a telescopic rod. The telescopic rod includes at least one of a hydraulic telescopic rod, an electric telescopic rod, and a pneumatic telescopic rod.

[0015] In one possible implementation, the offshore wind power foundation provided in this application includes a first drive unit comprising a telescopic rod that extends or shortens radially along the monopile foundation itself to allow the damping element to open and close relative to the monopile foundation; and a second drive unit comprising a support rod that supports and assists the damping element in opening and closing relative to the monopile foundation.

[0016] In one possible implementation, the offshore wind power foundation provided in this application also includes a controller and a monitor. The monitor is communicatively connected to the controller and is used to monitor the motion response of the monopile foundation. The controller is communicatively connected to the damping components and controls the operation of the drive components based on the motion response.

[0017] On the other hand, this application provides an offshore wind turbine generator set, including a generator set and the aforementioned offshore wind power foundation, wherein the generator set is installed on a monopile foundation of the offshore wind power foundation.

[0018] The offshore wind power foundation provided in this application includes a monopile foundation and damping units. Multiple sets of damping units are arranged along the height of the monopile foundation. Each set of damping units includes multiple damping components, thus each damping component can cover at least a portion of the offshore wind power foundation. Each damping component includes a driving element and a damping element rotatably connected to the driving element. When the monopile foundation exhibits a motion response in one direction, the driving element drives the corresponding damping element to rotate, adjusting the opening angle of the damping element. This allows waves and currents to act on the damping surface, providing the damping element with a force in the opposite direction to the monopile foundation. This results in the damping element providing reverse resistance to the monopile foundation, reducing the structural load and motion response of the monopile foundation, thereby improving the stability of the offshore wind power foundation itself.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the preferred embodiments of this application will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] It should be noted that in the description of the embodiments of this application, the terms "upper", "lower", "inner", "outer" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0037] Furthermore, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] This application provides an offshore wind turbine generator set, including a generator set and an offshore wind power foundation, with the generator set connected to the offshore wind power foundation. When wind power acts on the generator set, the generator set converts the captured wind energy into electrical energy. The offshore wind power foundation supports the generator set to ensure its safe operation.

[0040] However, offshore wind turbine foundations need to withstand environmental loads such as waves, ocean currents, and sea ice, resulting in large loads on the foundations and making them prone to motion response, which in turn leads to a decrease in stability.

[0041] In view of this, one embodiment of this application provides a new offshore wind power foundation, which can be used for the offshore wind turbine generator provided in the above embodiments. The offshore wind power foundation can improve its stability through a damping unit.

[0042] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0043] See Figures 1 to 3 This application provides an offshore wind power foundation 10, which may include a monopile foundation 100 and damping units 200. The damping units 200 are disposed on the monopile foundation 100, and multiple sets of damping units 200 are distributed at intervals along the height direction X of the monopile foundation 100. Each set of damping units 200 includes multiple damping components 210, which are distributed at intervals around the circumferential direction Y of the monopile foundation 100. Each damping component 210 includes a driving member 211 and a damping member 212 rotatably connected to the driving member 211. The end of the driving member 211 away from the damping member 212 is connected to the monopile foundation 100. The side of the damping member 212 facing the outer circumferential surface of the monopile foundation 100 has a damping surface 2121, which can be set at a predetermined tilt angle relative to the height direction X of the monopile foundation 100. The driving member 211 drives the damping member 212 to rotate relative to the monopile foundation 100, so that the predetermined tilt angle is adjustable.

[0044] Understandably, the arrangement of multiple damping units 200 at intervals along the height direction X of the monopile foundation 100 can enhance the longitudinal bearing capacity and overturning resistance of the monopile foundation 100, enabling the monopile foundation 100 to better adapt to the dynamics of water flow and wind action at different depths.

[0045] The damping unit 200 can be provided in two, three or more sets along the height direction X. The specific number can be set according to the height of the single pile foundation 100, and this application does not limit it.

[0046] It should be noted that each damping unit 200 includes multiple damping components 210, which are arranged sequentially around the circumferential Y-axis of the monopile foundation 100. To reduce the structural load and motion response of the monopile foundation 100, each damping component 210 may include a driving element 211 and a damping element 212. One end of the driving element 211 is connected to the monopile foundation 100, and the other end is flexibly connected to the damping element 212 via a rotational connection. This allows the damping element 212 to rotate relative to the monopile foundation 100 under the driving force of the driving element 211; or, in other words, the damping element 212 can open and close relative to the monopile foundation 100 under the drive of the driving element 211.

[0047] The structural load of the single pile foundation 100 can be understood as the force borne by the single pile foundation 100, such as wind force, wave load, water flow impact force, etc. The motion response can be understood as the displacement, velocity (the rate at which the single pile foundation 100 displaces under load), and acceleration (the rate at which the single pile foundation 100 changes velocity under load).

[0048] Optionally, the drive component 211 can be a combination of a motor and a lead screw, a pneumatic telescopic component, a hydraulic telescopic component, or other structures.

[0049] It should also be noted that a damping surface 2121 is provided on the side of the damping element 212 facing the outer periphery of the monopile foundation 100. The damping surface 2121, through the driving element 211, can form different predetermined inclination angles relative to the height direction X of the monopile foundation 100 according to the structural load borne by the monopile foundation 100 and its motion response. By setting the adjustable inclination angle of the damping surface 2121, the driving element 211 can adjust the opening angle of the predetermined inclination angle of the damping surface 2121 according to the motion response of the monopile foundation 100, so that waves and ocean currents can act on the damping surface 2121. Thus, the damping element 212 can provide reverse resistance to the monopile foundation 100, thereby enhancing the dynamic response capability of the monopile foundation 100, effectively dissipating the energy brought by waves and wind, reducing the vibration and displacement of the monopile foundation 100, and thus improving the stability of the offshore wind power foundation 10 itself.

[0050] The monopile foundation 100 has two opposing sides along its radial direction. Taking the monopile foundation 100 moving towards one side as an example, the damping element 212 on the other side opens relative to the monopile foundation 100 under the drive of the drive element 211. That is, when the monopile foundation 100 does not move, the predetermined angle of the damping surface 2121 relative to the height direction X can be 0°. When the monopile foundation 100 moves, the drive element 211 drives the damping element 212 at the corresponding position to rotate, so as to appropriately increase the predetermined angle of the damping surface 2121 relative to the height direction X according to the movement response. As a result, wave loads and water flow impact forces can act on the damping surface 2121, causing the damping element 212 to increase the reverse resistance, thereby reducing the structural load and movement response of the monopile foundation 100 and improving the stability of the offshore wind power foundation 10 itself.

[0051] In some embodiments, the predetermined tilt angle is greater than or equal to 0° and less than or equal to 60°.

[0052] Exemplarily, the monopile foundation 100 has a first end and a second end opposite to each other along the height direction X. The first end can be used for connection to a generator set. The damping member 212 can be configured to be inclined towards the side where the first end is located, so that the damping surface 2121 faces the first end. Alternatively, the damping member 212 can also be configured to be inclined towards the side where the second end is located, so that the damping surface 2121 faces the second end. The purpose is to achieve the damping effect of the damping member 212, and this application does not limit it.

[0053] It should be noted that, see Figure 2 The predetermined inclination angle is A. By setting the predetermined inclination angle within the range of 0° to 60°, the driving component 211 can adjust the opening and closing angle of the corresponding damping component 212 according to the structural load and motion response of the monopile foundation 100, so that the damping component 212 can provide sufficient reverse resistance to reduce the structural load and motion response of the monopile foundation 100. If the predetermined inclination angle is too large, such as 80° or 90°, the damping component 212 will have difficulty providing sufficient reverse resistance, which will lead to a decrease in damping effect.

[0054] See Figure 3 In some embodiments, along the circumferential Y direction, the interval angle between two adjacent damping components 210 in each group of damping units 200 is less than or equal to 60°.

[0055] Setting the interval angle between adjacent damping components 210 to less than 60°, such as 45° or 40°, can improve the response speed and damping effect of the damping unit 200. When the monopile foundation 100 generates a motion response, the damping components 210 can work together to reduce the structural load and motion response of the monopile foundation 100 through the different opening and closing angles of each damping element 212. In other words, a smaller interval angle between adjacent damping components 210 can increase the reverse resistance provided by the damping unit 200, thereby improving the stability of the offshore wind power foundation 10 itself.

[0056] Furthermore, this arrangement helps improve the reliability and durability of the damping unit 200. During long-term use, the coordinated use of adjacent damping components 210 helps reduce the risk of loosening or damage to the damping components 210. Simultaneously, the uniform damping distribution can also reduce structural fatigue problems in the damping components 210 caused by localized overloads, thereby extending the service life of the damping unit 200.

[0057] In some alternative embodiments, along the height direction X, the orthographic projections of each damping component 210 in at least two sets of damping units 200 are staggered from each other.

[0058] With this configuration, each damping unit 200 can form a denser damping network, which can more effectively absorb wave loads and water flow impacts from different directions, thereby providing better reverse resistance to the monopile foundation 100 and improving the stability of the offshore wind power foundation 10 itself.

[0059] It should be noted that when the interval angle between two adjacent damping components 210 is large, such as 60°, the damping components 210 along the height direction X can be staggered. When the interval angle between two adjacent damping components 210 is small, such as 15°, it is not necessary to stagger the damping components 210 along the height direction X, and this application does not impose any restrictions on this.

[0060] In some embodiments, along the height direction X, the spacing between any two adjacent damping units 200 in each group of damping units 200 is less than or equal to 0.5m.

[0061] Understandably, setting the interval between any two adjacent sets of damping units 200 to less than or equal to 0.5m, such as 0.4m or 0.35m, allows the damping units 200 to work together more effectively, improving the damping effect and thus enhancing the stability of the offshore wind power foundation 10. Conversely, if the interval between any two adjacent sets of damping units 200 is too large, such as 1m, the synergistic effect between the damping units 200 will be affected, leading to a decrease in the damping effect.

[0062] In some embodiments, along the height direction X, the thickness of each damping element 212 in at least a portion of the damping units 200 is the same. The thickness of each damping element 212 in at least a portion of the damping units 200 gradually decreases.

[0063] Specifically, the damping elements 212 located above the lowest tide level can be configured to have a uniform thickness, thereby ensuring that each damping element 212 can provide relatively balanced and stable damping performance. Furthermore, the damping elements 212 located below the lowest tide level can be configured to gradually decrease in size along the direction away from the lowest tide level. Along the direction away from the lowest tide level, the wave load and water flow impact force on the damping elements 212 are relatively reduced. This configuration can alleviate the fatigue burden on the damping units 200 below the lowest tide level, thereby achieving a more efficient damping effect.

[0064] In some embodiments, the damping member 212 includes a damping plate 2122, which includes at least one of a flat damping plate 2122a, a fan-shaped damping plate 2122b, and an arc-shaped damping plate 2122c.

[0065] Among them, see Figure 5 The flat damping plate 2122a has a relatively simple structure and is easy to manufacture. (See also...) Figure 6 The fan-shaped damping plate 2122b can effectively absorb and dissipate wave loads and water flow impact forces, thereby providing reverse resistance to the monopile foundation 100.

[0066] It should be noted that, see Figure 4 and Figure 7 The arc-shaped damping plate 2122c may include an arc-shaped damping plate 2122c arranged in an arc along the height direction X and an arc-shaped damping plate 2122c arranged in an arc along the circumferential direction Y of the monopile foundation 100. The arc-shaped damping plate 2122c arranged in an arc along the height direction X may be recessed in a direction away from the monopile foundation 100.

[0067] For example, in sea areas with relatively large wave loads and water flow impact forces, the damping plate 2122 can be set as an arc-shaped damping plate 2122c arranged in an X-shape along the height direction. Thus, the damping plate 2122 can better withstand wave loads and water flow impact forces, providing reverse resistance for the monopile foundation 100.

[0068] See Figure 1 In some embodiments, the damping member 212 may include a first connecting portion 2123 and a second connecting portion 2124. The driving member 211 may include a first driving portion 2111 and a second driving portion 2112, wherein the first driving portion 2111 is rotatably connected to the first connecting portion 2123, and the second driving portion 2112 is rotatably connected to the second connecting portion 2124, and at least one of the first driving portion 2111 and the second driving portion 2112 is used to drive the damping member 212 to rotate.

[0069] To achieve the connection between the damping element 212 and the driving element 211, and the driving action of the driving element 211 on the damping element 212, the damping element 212 may be provided with a first connecting portion 2123 and a second connecting portion 2124. Correspondingly, the driving element 211 may be provided with a first driving portion 2111 and a second driving portion 2112. The first connecting portion 2123 and the first driving portion 2111, and the second connecting portion 2124 and the second driving portion 2112, can be rotatably connected by hinges.

[0070] At least one of the first drive unit 2111 and the second drive unit 2112 is configured to have a drive function, that is, at least one of the first drive unit 2111 and the second drive unit 2112 can drive the damping member 212 to rotate by a drive method such as motor, hydraulic or pneumatic.

[0071] In some embodiments, at least one of the first drive unit 2111 and the second drive unit 2112 includes a telescopic rod, which includes at least one of a hydraulic telescopic rod, an electric telescopic rod, and a pneumatic telescopic rod.

[0072] Understandably, the telescopic rod can adjust its length according to actual needs, thereby driving the damping component 212 to rotate.

[0073] In a specific implementation, the first driving part 2111 can be configured as a telescopic rod, and the second driving part 211 can be configured as a support rod, which can support the damping part 212. That is, the first driving part 2111 drives the damping part 212 to rotate by adjusting its own length, and the second connecting part 2124 rotates relative to the second driving part 2112 to cooperate in realizing the rotation of the damping part 212. Alternatively, the second driving part 2112 can be configured as a telescopic rod, and the first driving part 2111 can be configured as a support rod. Or, both the first driving part 2111 and the second driving part 2112 can be configured as telescopic rods.

[0074] For example, the telescopic rod includes at least one of a hydraulic telescopic rod, an electric telescopic rod, and a pneumatic telescopic rod. A hydraulic telescopic rod utilizes the pressure transmission characteristics of a hydraulic system to achieve precise control and rapid response. An electric telescopic rod uses a motor to drive a lead screw to achieve smooth extension and retraction of the rod and rotation of the damping element 212. A pneumatic telescopic rod uses compressed air as a power source, achieving the extension and retraction function of the rod through the piston movement of a cylinder.

[0075] See Figure 1 and Figure 2 In some embodiments, the first drive unit 2111 includes a telescopic rod that extends or shortens radially along the monopile foundation 100 itself to open and close the damping element 212 relative to the monopile foundation 100. The second drive unit 2112 includes a support rod for supporting and assisting the damping element 212 in opening and closing relative to the monopile foundation 100.

[0076] In practice, the telescopic rod can extend or shorten radially along the monopile foundation 100, allowing the damping element 212 to open and close relative to the monopile foundation 100 according to its motion response. The second drive unit 2112 is configured as a support rod to provide support force to the damping element 212 and also assist the damping element 212 in opening and closing relative to the foundation body. By providing the support rod, the stability of the damping element 212 can be improved, ensuring that it maintains rigidity and durability during the opening and closing process.

[0077] During the operation of the damping assembly 210, the telescopic rod first drives the damping element 212 to start opening and closing through its extension or retraction action. Then, the support rod provides the necessary support and assistance to ensure that the damping element 212 can rotate smoothly during the opening and closing process.

[0078] In some embodiments, a controller and a monitor are also included, the monitor being communicatively connected to the controller and used to monitor the motion response of the monopile foundation 100. The controller is communicatively connected to the damping assembly 210 and controls the operation of the drive unit 211 based on the motion response.

[0079] The monitor can be installed on the monopile foundation 100, or, in some alternative embodiments, the monitor can also be installed on the generator set. The monitor may include an acceleration sensor capable of monitoring the motion response of the monopile foundation 100 in real time and accurately.

[0080] The controller receives and processes information from the monitor and issues commands accordingly. The controller is communicatively connected to the damping assembly 210 and can control the operation of the drive unit 211 as needed. When the monitor detects displacement in the monopile foundation 100, the controller responds quickly, determines the resistance required from the damping assembly 212 and the required rotation angle of the damping assembly 212, and transmits the predetermined angles of each damping assembly 212 to the corresponding drive unit 211. This allows the drive unit 211 to adjust the predetermined angles of the damping assemblies 212 according to the motion response of the monopile foundation 100, enabling the damping assemblies 212 to provide reverse resistance to the monopile foundation 100, thereby reducing the motion response of the monopile foundation 100.

[0081] Based on the above embodiments, this application provides an offshore wind turbine generator set, including a generator set and an offshore wind power foundation 10 provided in any of the above embodiments, wherein the generator set is installed on a monopile foundation 100 of the offshore wind power foundation 10.

[0082] The offshore wind power foundation 10 has been described in detail in the above embodiments and will not be repeated here.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
