Description

Technical Field

[0001] This invention relates to the field of offshore wind power, and in particular to a node reinforcement member for wind turbine jackets, wind turbine jackets, and wind turbine generators. Background Technology

[0002] Wind turbine jackets mainly consist of main pipes and branch pipes, forming a stable frame structure through complex connections to support the main unit and blades of the wind turbine generator. Traditional wind turbine jacket designs often focus on meeting basic structural strength and stability requirements, but in the deep-sea environment, the long-term effects of complex marine environmental factors such as ocean currents, waves, and tides pose a severe challenge to the durability of the jackets.

[0003] In related technologies, traditional wind turbine jacket structures often fail to meet structural strength requirements in deep-sea areas, especially in waters deeper than 50 meters, due to limitations in length and weight, posing safety hazards. The connection nodes between the main pipe and branch pipes are weak points in the jacket structure, easily affected by ocean currents and fatigue loads, leading to connection failure or structural damage. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a node reinforcement member for wind turbine jackets. According to the node reinforcement member of this invention, through the synergistic effect of the first reinforcement member, the first connector, and the second reinforcement member, the overall rigidity and stability of the wind turbine jacket are significantly enhanced, external loads are effectively distributed and balanced, and the service life of the wind turbine jacket is extended.

[0005] The present invention also proposes a wind power jacket with the above-mentioned node reinforcement components.

[0006] The present invention also proposes a wind turbine with the above-mentioned wind power jacket structure.

[0007] According to the present invention, a node reinforcement member is used for a wind turbine jacket, the wind turbine jacket including a main pipe and a branch pipe, the main pipe being configured as a plurality of such main pipes spaced apart in the circumferential direction of the wind turbine jacket, the branch pipes being connected between two adjacent main pipes, the node reinforcement member including: a first reinforcement member, the first reinforcement member being arranged around to be adapted to wrap the outer peripheral wall of the main pipe; a first connector, the first connector being configured as a plurality of such connectors disposed on one side of the first reinforcement member, one end of each first connector being connected to the first reinforcement member, and the other end being connected to a second reinforcement member (13); a second reinforcement member, the second reinforcement member being arranged around to be adapted to wrap the outer peripheral wall of the branch pipe, the second reinforcement member being configured as a plurality of such connectors corresponding to the plurality of first connectors, each second reinforcement member being connected to the other end of the corresponding first connector.

[0008] The node reinforcement member according to the present invention is used for wind turbine jacket structures, which include main pipes and branch pipes. The main pipes are configured as multiple pipes spaced apart circumferentially on the wind turbine jacket structure. The multiple main pipes are arranged in a ring-like pattern with intervals between them, collectively forming the main support structure of the wind turbine jacket structure. Branch pipes connect adjacent main pipes; the branch pipes serve to connect and stabilize the main pipes, transmitting forces between the two main pipes and ensuring the stability of the wind turbine jacket structure.

[0009] The wind turbine jacket includes a first reinforcing member, which is arranged around the main pipe so that its shape and size are sufficient to wrap around the outer peripheral wall of the main pipe, thereby enhancing the strength and rigidity of the main pipe and improving its ability to resist external loads.

[0010] The wind turbine jacket also includes a second reinforcing member, which is arranged around the branch pipe. The shape and size of the second reinforcing member are such that it can wrap around the outer wall of the branch pipe to enhance the strength and rigidity of the branch pipe and improve its ability to resist external loads.

[0011] The wind turbine jacket also includes first connectors for connecting first and second reinforcing members. Multiple first connectors are configured to be located on one side of the first reinforcing member. Specifically, for the wind turbine jacket, all first connectors are located on one side of the corresponding first reinforcing member between multiple main pipes, so that all first connectors extend towards the multiple main pipes to connect with branch pipes between the main pipes. One end of each first connector is connected to the first reinforcing member, and the other end of each first connector is connected to the second reinforcing member, making the connection between the main pipe and the branch pipe tighter, increasing the force transmission channel between the main pipe and the branch pipe, effectively transferring the load on the branch pipe to the main pipe, and distributing it evenly within the wind turbine jacket structure.

[0012] The second reinforcing member is constructed in multiple ways, corresponding to multiple first connecting members, with each second reinforcing member connected to the other end of its corresponding first connecting member. This allows the main pipe to connect with multiple surrounding branch pipes through the multiple second reinforcing members, further enhancing the overall rigidity and stability of the wind turbine jacket. Because the multiple second reinforcing members are distributed around the main pipe and tightly connected to their respective branch pipes, the node reinforcing components can effectively distribute and balance loads in different directions and angles, preventing local overload and stress concentration, thereby extending the service life of the wind turbine jacket.

[0016] According to some embodiments of the present invention, the first connecting portion forms a through first mounting hole, the second connecting portion forms a through second mounting hole, and the first mounting hole and the second mounting hole communicate with each other; the node reinforcement structure further includes a fastener, the fastener passing through the first mounting hole and the second mounting hole.

[0017] According to some embodiments of the present invention, at least one of the second reinforcing members is symmetrical about the connection point connected to the first connecting member.

[0018] According to some embodiments of the present invention, a plurality of second reinforcing members are arranged rotationally symmetrically around the first reinforcing member.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In related technologies, traditional wind turbine jacket structures often fail to meet structural strength requirements in deep-sea areas, especially in waters deeper than 50 meters, due to limitations in length and weight, posing safety hazards. The connection nodes between the main pipe and branch pipes are weak points in the jacket structure, easily affected by ocean currents and fatigue loads, leading to connection failure or structural damage.

[0042] The following is for reference. Figures 1-5 The node reinforcement member 1 according to an embodiment of the present invention is described.

[0043] like Figures 1-4As shown, the node reinforcement member 1 according to the present invention is used for a wind turbine jacket 2. The wind turbine jacket 2 includes main pipes 21 and branch pipes 22. The main pipes 21 are configured to be multiplely spaced apart in the circumferential direction of the wind turbine jacket 2. The multiple main pipes 21 are arranged in a ring and are spaced apart from each other, together forming the main support structure of the wind turbine jacket 2. The branch pipes 22 are connected between two adjacent main pipes 21; the branch pipes 22 serve to connect and stabilize the main pipes 21, and can transmit forces between the two main pipes 21 to ensure the stability of the wind turbine jacket 2 structure.

[0044] The wind turbine jacket 2 includes a first reinforcing member 11, which is arranged around the main pipe 21. The shape and size of the first reinforcing member 11 are such that it can wrap around the outer peripheral wall of the main pipe 21 to enhance the strength and rigidity of the main pipe 21 and improve the ability of the main pipe 21 to resist external loads.

[0045] The wind turbine jacket 2 also includes a second reinforcing member 13, which is arranged around the perimeter so that the shape and size of the second reinforcing member 13 can wrap around the outer peripheral wall of the branch pipe 22 to enhance the strength and rigidity of the branch pipe 22 and improve the ability of the branch pipe 22 to resist external loads.

[0046] The wind turbine jacket 2 also includes first connectors 12, which connect the first reinforcing member 11 to the second reinforcing member 13. Multiple first connectors 12 are configured to be disposed on one side of the first reinforcing member 11. Specifically, for the wind turbine jacket 2, all first connectors 12 are located on one side of the corresponding first reinforcing member 11 between multiple main pipes 21, so that all first connectors 12 extend towards the multiple main pipes 21 to connect with the branch pipes 22 between the multiple main pipes 21. One end of each first connector 12 is connected to the first reinforcing member 11, and the other end of each first connector 12 is connected to the second reinforcing member 13, making the connection between the main pipe 21 and the branch pipe 22 tighter, increasing the force transmission channel between the main pipe 21 and the branch pipe 22, effectively transferring the load on the branch pipe 22 to the main pipe 21, and distributing it evenly within the structure of the wind turbine jacket 2.

[0047] The second reinforcing member 13 is constructed in multiple ways corresponding to the multiple first connecting members 12, and each second reinforcing member 13 is connected to the other end of the corresponding first connecting member 12. This allows the main pipe 21 to establish connections with multiple surrounding branch pipes 22 through the multiple second reinforcing members 13, further enhancing the overall rigidity and stability of the wind turbine jacket 2. Since the multiple second reinforcing members 13 are distributed around the main pipe 21 and are tightly connected to their respective corresponding branch pipes 22, the node reinforcing member 1 can effectively distribute and balance the load in different directions and angles, preventing local overload and stress concentration, thereby extending the service life of the wind turbine jacket 2.

[0048] Therefore, according to the node reinforcement member 1 of the present invention, through the synergistic effect of the first reinforcement member 11, the first connector 12 and the second reinforcement member 13, the overall rigidity and stability of the wind power jacket 2 are significantly enhanced, the external load is effectively distributed and balanced, and the service life of the wind power jacket 2 is extended.

[0049] According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the node strengthening member 1 also includes a second connector 14, which connects two adjacent second strengthening members 13 to further connect the two adjacent second strengthening members 13, increasing the structural strength and stiffness of the node strengthening member 1. By setting the second connector 14, not only is the connection strength between adjacent branch pipes 22 enhanced, but the entire wind turbine jacket 2 can also better distribute and balance stress when subjected to external loads, reducing the risk of stress concentration.

[0050] According to some embodiments of the present invention, such as Figures 3-5 As shown, at least one of the first reinforcing member 11 and the second reinforcing member 13 includes a first arc-shaped plate 151 and a second arc-shaped plate 152. By splicing and assembling the first arc-shaped plate 151 and the second arc-shaped plate 152 to form the first reinforcing member 11 or the second reinforcing member 13, the prefabricated construction of the node reinforcement component is realized, the installation process is simplified, and it is easy to replace, which can avoid wet work during the construction process.

[0051] One of the first arc-shaped plate 151 and the second arc-shaped plate 152 is connected to the first connector 12 to establish a connection between the first reinforcing member 11 and the second reinforcing member 13. Specifically, in some embodiments, the first reinforcing member 11 includes the first arc-shaped plate 151 and the second arc-shaped plate 152. By connecting one of the first arc-shaped plate 151 and the second arc-shaped plate 152 to the first connector 12, the first reinforcing member 11 can be connected to the second reinforcing member 13 via the first connector 12. In some embodiments, the second reinforcing member 13 includes the first arc-shaped plate 151 and the second arc-shaped plate 152. By connecting one of the first arc-shaped plate 151 and the second arc-shaped plate 152 to the first connector 12, the second reinforcing member 13 can be connected to the first reinforcing member 11 via the first connector 12.

[0052] The first arc-shaped plate 151 has a first reinforcing surface 1511, and the second arc-shaped plate 152 has a second reinforcing surface 1521. Both the first reinforcing surface 1511 and the second reinforcing surface 1521 are constructed as arc-shaped surfaces, which conform to the contour of the outer peripheral wall of the main pipe 21 or the branch pipe 22, so that the first arc-shaped plate 151 and the second arc-shaped plate 152 can fit tightly against the outer peripheral wall of the main pipe 21 or the branch pipe 22. After the first arc-shaped plate 151 and the second arc-shaped plate 152 are spliced ​​and assembled, the first reinforcing surface 1511 and the second reinforcing surface 1521 are arranged opposite to each other in the radial direction of the corresponding first reinforcing member 11 or second reinforcing member 13 and protrude away from each other. Therefore, the first reinforcing surface 1511 and the second reinforcing surface 1521 can cooperate with each other and tightly wrap around the outer peripheral wall of the main pipe 21 or the branch pipe 22 from both sides, so that the stress is more evenly distributed during the transmission process, thereby further improving the load-bearing capacity and stability of the node.

[0053] According to some embodiments of the present invention, such as Figure 3 As shown, both the first reinforcing member 11 and the second reinforcing member 13 include a first arc-shaped plate 151 and a second arc-shaped plate 152. The first arc-shaped plate 151 of the first reinforcing member 11 is connected to the first arc-shaped plates 151 of the second reinforcing members 13 via multiple first connecting members 12 to form a pre-assembled component. When the node reinforcing member 1 is assembled onto the wind turbine duct frame 2, the pre-assembled component is first installed between the main pipe 21 and the branch pipe 22, with the first arc-shaped plate 151 of the first reinforcing member 11 attached to the outer peripheral wall of the main pipe 21, and the first arc-shaped plate 151 of the second reinforcing member 13 attached to the outer peripheral wall of the branch pipe 22, thus realizing the installation of the pre-assembled component. Subsequently, the second arc-shaped plate 152 of the first reinforcing member 11 is spliced ​​with the first arc-shaped plate 151 already installed on the main pipe 21, and tightly wraps around the main pipe 21 from the other side. Similarly, the second arc-shaped plate 152 of the second reinforcing member 13 is spliced ​​with the second arc-shaped plate 152 already installed on the branch pipe 22, and tightly wrapped around the branch pipe 22 from the other side, thereby completing the assembly of the entire node reinforcing member 1.

[0054] Pre-assembled components can be pre-assembled in the factory, ensuring product quality and reducing the number of parts, thus simplifying the on-site installation process. In a factory environment, advanced manufacturing equipment can be used to precisely process and assemble the first reinforcing member 11, the second reinforcing member 13, and the first connecting member 12.

[0055] According to some embodiments of the present invention, such as Figure 3 As shown, the pre-assembled parts also include a second connector 14, which connects between the first arcuate plates 152 of two adjacent second reinforcing members 13 to enhance the overall stability and rigidity of the pre-assembled parts.

[0056] According to some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the edge of the first arc-shaped plate 151 has an outwardly extending first connecting portion 1512, that is, the first connecting portion 1512 extends from the edge of the first arc-shaped plate 151 in a direction away from the first arc-shaped plate 151. Similarly, the edge of the second arc-shaped plate 152 has an outwardly extending second connecting portion 1522, that is, the second connecting portion 1522 extends from the edge of the second arc-shaped plate 152 in a direction away from the second arc-shaped plate 152. The first connecting portion 1512 and the second connecting portion 1522 can cooperate with each other to firmly connect the first arc-shaped plate 151 and the second arc-shaped plate 152 together.

[0057] Specifically, the first connecting portion 1512 has a first connecting surface, while the second connecting portion 1522 has a second connecting surface. After the first arc-shaped plate 151 and the second arc-shaped plate 152 are assembled together, the first connecting surface and the second connecting surface are in a relative and matched state in the radial direction of the corresponding first reinforcing member 11 or second reinforcing member 13. Therefore, when the first arc-shaped plate 151 and the second arc-shaped plate 152 are placed together, the first connecting surface and the second connecting surface can be precisely aligned and in contact with each other, thereby forming a stable connection interface.

[0058] By matching the first connecting part 1512 with the second connecting part 1522, the installation process can be simplified and the connection stability and reliability can be improved.

[0059] According to some embodiments of the present invention, such as Figure 4 As shown, the first connecting portion 1512 has a through first mounting hole, which is pre-set for the fastener 16 to pass through when it is subsequently installed. Similarly, the second connecting portion 1522 has a through second mounting hole, which is also pre-set for the fastener 16 to pass through when it is subsequently installed.

[0060] When the first arc plate 151 and the second arc plate 152 are spliced ​​together in a predetermined position and direction, the first mounting hole of the first connecting part 1512 and the second mounting hole of the second connecting part 1522 will naturally align and communicate with each other, so that the fastener 16 passes through the first mounting hole and the second mounting hole.

[0061] The node reinforcement structure also includes a fastener 16, which passes through the first mounting hole and the second mounting hole to securely lock the first arc plate 151 and the second arc plate 152 together, thus effectively preventing the first arc plate 151 and the second arc plate 152 from separating or misaligning when subjected to external force.

[0062] By using fastener 16, the installation process is simplified, and the reliability and durability of the connection are improved. Fastener 16 can also be easily disassembled and reinstalled, thereby reducing maintenance costs and time.

[0063] According to some embodiments of the present invention, the fastener 16 is constructed as a grooved rivet, which not only effectively prevents the connection from loosening during long-term use, but also exhibits excellent vibration resistance, ensuring the stability and reliability of the node reinforcement component. Furthermore, due to the significant fastening effect of the grooved rivet, structural failures caused by connection problems are reduced, thereby lowering the maintenance and monitoring costs of the structure during later operation and improving overall economic efficiency.

[0064] According to some embodiments of the present invention, such as Figure 1 As shown, at least one second reinforcing member 13 is symmetrical about the connection point with the first connecting member 12. The connection point is the point where the second reinforcing member 13 contacts and is fixed together with the first connecting member 12. The second reinforcing member 13 and the first connecting member 12 can be fixed together by various methods such as welding or integral molding. The second reinforcing member 13 has a mirror-symmetrical layout or shape at the connection point, which allows the second reinforcing member 13 to distribute the external force more evenly when subjected to the external force transmitted from the first connecting member 12, thereby reducing the risk of local stress concentration. This not only improves the strength and durability of the second reinforcing member 13 itself, but also enhances the stability and safety of the entire wind turbine jacket 2 structure.

[0065] According to some embodiments of the present invention, such as Figure 1 As shown, multiple second reinforcing members 13 are arranged rotationally symmetrically around the first reinforcing member 11. The arrangement of the multiple second reinforcing members 13 follows the principle of rotational symmetry, that is, no matter which direction is viewed, the position and distribution of the multiple second reinforcing members 13 relative to the first reinforcing member 11 are uniform and symmetrical, which helps to balance the stress on the structure and improve the stability and durability of the overall structure.

[0066] According to some embodiments of the present invention, such as Figure 1 As shown, the second reinforcing member 13 is symmetrically arranged radially with an adjacent second reinforcing member 13 of the first reinforcing member 11. Radial refers to the straight line extending radially from the center of the first reinforcing member 11. The presence of two second reinforcing members 13 symmetrical about the first reinforcing member 11 in the radial direction establishes connections between the main pipe 21 and the branch pipes 22 on both sides, and helps to disperse and balance forces from various directions, enabling the entire structure to remain stable under external forces and reducing local stress concentration and deformation.

[0067] The second reinforcing member 13 is symmetrically arranged with the adjacent second reinforcing member 13 along the axial direction of the first reinforcing member 11. The axial direction refers to the straight line along the central axis of the first reinforcing member 11. The symmetrical arrangement of the second reinforcing members 13 along the axial direction of the first reinforcing member 11 enhances the stability of the structure, helps to balance the axial stress on the structure, and reduces bending or torsional deformation caused by non-uniform stress. Furthermore, the axially symmetrical arrangement of the second reinforcing members 13 simplifies the design and manufacturing process, improves construction efficiency and accuracy, and provides strong protection for the reliability and durability of the engineering structure.

[0068] According to some embodiments of the present invention, the node reinforcing member 1 further includes second connecting members 14. Two second connecting members 14 are configured to be symmetrically arranged axially on the first reinforcing member 11. One second connecting member 14 connects between two adjacent second reinforcing members 13 radially on the first reinforcing member 11, and the other second connecting member 14 connects between two other adjacent second reinforcing members 13 radially on the first reinforcing member 11. The two second connecting members 14 respectively connect different, radially adjacent second reinforcing members 13. Each second connecting member 14 strengthens the connection strength between two adjacent second reinforcing members 13 radially on the first reinforcing member 11. The symmetrical arrangement of the two second connecting members 14 axially on the first reinforcing member 11 further improves the overall balance and torsional resistance of the node reinforcing member 1, enabling the node reinforcing member 1 to bear force evenly under complex loads, avoiding stress concentration and localized failure.

[0069] According to some embodiments of the present invention, such as Figure 1 As shown, the center of the first reinforcing member 11 is located at the weld joint of the main pipe 21, enhancing the strength and toughness of the weld area. This is because welds are often the weakest parts of a structure, prone to cracking and propagation under alternating loads. By aligning the center of the first reinforcing member 11 with the weld joint, not only can the concentrated stress at the weld joint be dispersed, but the material cross-section can also be increased to resist possible crack propagation, significantly improving the overall durability and safety of the main pipe 21.

[0070] The position of the second reinforcing member 13 can be adjusted according to the location of the weak point of the branch pipe 22. By determining the weak point on the branch pipe 22, the second reinforcing member 13 is then strategically placed at the weak point to effectively alleviate and disperse local stress, thereby maximizing the load-bearing capacity of the branch pipe 22 and ensuring the stable operation of the entire wind power jacket 2 under complex working conditions.

[0071] The following is a brief description of the wind power jacket 2 according to the present invention.

[0072] The wind turbine jacket 2 according to the present invention includes the node reinforcement member 1 in any of the above embodiments. Because the wind turbine jacket 2 according to the present invention includes the node reinforcement member 1 in any of the above embodiments, the wind turbine jacket 2 according to the present invention significantly improves overall rigidity and stability, effectively distributes and balances external loads, thereby significantly extending its service life.
