[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.
[0041] This disclosure provides a wind turbine generator set, which may include a tower foundation and a tower fixed above the tower foundation. The tower may be composed of multiple tower segments stacked longitudinally and connected as a whole by prestressed components. For example, but not limited to, the tower may include at least one concrete tower segment and at least one steel tower segment, with the steel tower segment disposed above the concrete tower segment. A transition segment is provided between the bottom steel tower segment and the top concrete tower segment, and the transition segment connects the adjacent tower segment and the concrete tower segment.
[0042] Reference Figure 1 This disclosure provides a tower section, which may include an anchor bolt assembly structure 1 and a concrete component 2, wherein the anchor bolt assembly structure 1 is disposed in the concrete component 2. As an example, the concrete component 2 includes a connection portion 19, at which the bolt assembly structure is disposed.
[0043] Specifically, in an exemplary embodiment of this disclosure, the anchor bolt assembly structure 1 includes a top wall 11 and a bottom wall 12 spaced apart, a prestressed member 13, and a load-bearing assembly. The top wall 11 is located above the bottom wall 12, the prestressed member 13 is connected between the top wall 11 and the bottom wall 12, and the load-bearing assembly is supported below the bottom wall 12. As an example, the load-bearing assembly is embedded in a concrete component 2, the top wall 11 is disposed on the top of the concrete component 2, and the prestressed member 13 located between the top wall 11 and the load-bearing assembly is embedded in the concrete component 2.
[0044] The tower section provided in this embodiment improves the overall structural strength of the tower section by incorporating an anchor bolt assembly structure 1 within the concrete component 2. Furthermore, the low cost of the concrete component 2 and the simple structure of the anchor bolt assembly structure 1 contribute to the excellent economic efficiency of the tower section.
[0045] Continue to refer to Figure 1 and Figure 2 In this embodiment, the bottom wall 12 and the top wall 11 are both annular, and the top wall 11 is arranged approximately parallel to the top of the bottom wall 12. The top wall 11 and the bottom wall 12 are each provided with through holes for the prestressed member 13 to pass through, so that the prestressed member 13 can be fixed to the top wall 11 and the bottom wall 12, but this is not a limitation. As an example, the top wall 11 and the bottom wall 12 can be stainless steel parts, for example, but not limited to, the top wall 11 and the bottom wall 12 can be stamped as a single piece, or they can be formed by assembling multiple arc segments.
[0046] In this embodiment, the top wall 11 has multiple through holes, which are spaced at equal angles along the circumference of the top wall 11, but this is not a limitation. The bottom wall 12 also has multiple through holes, which are spaced at equal angles along the circumference of the bottom wall 12, but this is not a limitation. In this embodiment, the through holes on the top wall 11 can be aligned with the through holes on the bottom wall 12 so that the prestressed member 13 extends approximately along the axial direction of the bottom wall 12, thereby better bearing the axial pressure of the upper tower section.
[0047] As an example, the prestressed member 13 is a prestressed rod, prestressed anchor cable, or prestressed steel strand with applied prestress.
[0048] Continue to refer to Figure 1 and Figure 2 The force-bearing component includes a plurality of force-bearing units 14, which are spaced apart circumferentially along the bottom wall 12 to enable the bottom wall 12 to remain balanced.
[0049] As an example, each bearing unit 14 includes a base 141 and a pair of support ribs 142. Each pair of support ribs 142 is connected between the base 141 and the bottom wall 12. Each pair of support ribs 142 is respectively arranged on the radial inner side and the radial outer side of the circumference where the prestressed member 13 is located, which is more conducive to the leveling of the bottom wall 12.
[0050] Optionally, the support rib 142 and the bottom wall 12 can be connected by fasteners to facilitate leveling of the bottom wall 12. As an example, the bottom wall 12 is provided with an adjustment through hole for the support rib 142 to pass through. The support rib 142 can be connected to a fastener through the adjustment through hole. For example, but not limited to, the fastener can be a nut. The top end of the support rib 142 can be provided with an external thread that matches the fastener. In this way, the flatness of the bottom wall 12 can be adjusted by adjusting the length of the two support ribs 142.
[0051] As an example, each pair of support ribs 142 is symmetrically arranged relative to the circumference of the prestressed member 13, but this is not a limitation. To facilitate the stress distribution of the support ribs 142, the support ribs 142 are arranged parallel to the prestressed member 13. That is, in this embodiment, the prestressed member 13 and the support ribs 142 extend approximately longitudinally. When the tower section is used in a wind turbine generator set, the prestressed member 13 and the support ribs 142 are used to bear longitudinal pressure and avoid bearing bending moment, thereby improving the service life of the tower section.
[0052] In this embodiment, the base 141 can be a metal plate, such as, but not limited to, a stainless steel plate, and the two support ribs 142 can be stainless steel ribs.
[0053] The bearing unit 14 provided in this disclosure has a simple structure and low cost, further reducing the manufacturing cost of the tower section. The bearing unit 14 facilitates the leveling of the bottom wall 12, reducing the manufacturing difficulty of the anchor bolt assembly structure 1. Furthermore, the bearing unit 14 can share the tensile force of the prestressed member 13, improving the stress distribution on the concrete component 2, thereby increasing the service life of the tower section.
[0054] Reference Figure 3 In another exemplary embodiment of this disclosure, to improve the assembly efficiency of the anchor bolt assembly structure 1, the force-bearing component provided by this disclosure further includes a first chassis 15. The first chassis 15 is supported below the force-bearing unit 14, a base 141 is fixed to the first chassis 15, and a support rib 142 is located on the side of the base 141 opposite to the first chassis 15. Thus, by setting the first chassis 15, multiple force-bearing units 14 can be pre-installed on the first chassis 15 without on-site assembly, thereby improving the on-site assembly efficiency of the anchor bolt assembly structure 1.
[0055] As an example, multiple support units 14 can be arranged at equal angles along the circumference of the first chassis 15, but this is not a limitation. In this embodiment, the first chassis 15 is annular, arranged parallel and spaced below the bottom wall 12, and the bottom wall 12 and the first chassis 15 are connected together by the support units 14. In this embodiment, the first chassis 15 can be a single piece, for example, but not limited to, the first chassis 15 can be formed by stamping a metal plate, or it can be formed by assembling multiple arc segments, all of which are within the protection scope of this disclosure.
[0056] In this embodiment, the assembly steps of the anchor bolt assembly structure 1 are roughly as follows:
[0057] First, prepare the first chassis 15 and level the first chassis 15 onto the operating table;
[0058] Multiple force-bearing units 14 are arranged circumferentially on the top surface of the first chassis 15, the base 141 is fixed to the first chassis 15, and the support ribs 142 extend upward along the axial direction of the first chassis 15.
[0059] Install the bottom wall 12 onto the support rib 142 and level the bottom wall 12;
[0060] A predetermined number of prestressed members 13 are connected to the bottom wall 12, and the prestressed members 13 are leveled. Specifically, the bottom end of the prestressed member 13 can be fixed to the bottom wall 12, for example, but not limited to, by fasteners. In this embodiment, three prestressed members 13 can be arranged at circumferential intervals on the bottom wall 12, and these three prestressed members 13 can be leveled, but this is not a limitation. In this way, by selectively setting a predetermined number of prestressed members 13, circumferential leveling of the prestressed members 13 can be achieved, improving the assembly speed of the anchor bolt assembly structure 1.
[0061] Install the top wall 11 on the top of the prestressed member 13 and level the prestressed member 13;
[0062] Finally, the remaining prestressed components 13 are installed, thus completing the overall assembly of the anchor bolt assembly structure 1.
[0063] The anchor bolt assembly structure 1 described above is placed in a predetermined mold, and can be cast and cured with concrete to form a tower section.
[0064] In this embodiment, the anchor bolt assembly structure 1 located below the top wall 11 and the concrete component 2 are fixed together, which facilitates stress diffusion and further improves the service life of the concrete component 2.
[0065] The tower section also includes prestressed ducts 22, which in this embodiment are disposed at the connection portion 19. Specifically, the prestressed ducts 22 are arranged at intervals on the radially inner side of the anchor bolt assembly structure 1 to facilitate the installation of prestressed members between the prestressed ducts 22 and the tower foundation.
[0066] In this embodiment, the tower section can be directly installed on the tower foundation, and can be a transition section connecting the concrete tower and the steel tower 21.
[0067] As a transitional section, continue to refer to Figure 1 The tower section also includes a connecting part 19 and a support part 20 arranged adjacent to each other along the axial direction of the tower section. The anchor bolt assembly structure 1 is disposed in the connecting part 19. The support part 20 extends downward from the bottom wall of the connecting part 19 along the axial direction of the tower section. The outer diameter of the top end of the support part 20 is equal to the outer diameter of the bottom end of the connecting part 19, so that the outer peripheral wall of the tower section is smoothly transitioned, improving the aesthetics of the tower section.
[0068] In this embodiment, the bottom inner diameter of the connecting part 19 is smaller than the top inner diameter of the support part 20, that is, the wall thickness of the connecting part 19 is greater than the wall thickness of the support part 20. This facilitates stress diffusion on the prestressed member 13, avoids excessive local stress, and thus improves the load-bearing capacity of the concrete component 2 to a certain extent, preventing excessive local stress from causing it to scatter, and improving the service life of the tower section. As an example, the prestressed member 13 is located on the radially inner side of the support part 20, but this is not a limitation.
[0069] The anchor assembly structure 1 provided in the second exemplary embodiment of this disclosure, and... Figure 1 The difference lies in the structure of the force-bearing component in this embodiment.
[0070] Specifically, refer to Figure 4 and Figure 5 The load-bearing component includes a second chassis 16 and an inclined support 17. The second chassis 16 is spaced apart below the bottom wall 12, and the inclined support 17 connects the outer edge of the bottom wall 12 and the outer edge of the second chassis 16. As an example, the bottom wall 12, the second chassis 16, and the inclined support 17 are a single integrated structure, but this is not a limitation. The bottom wall 12, the second chassis 16, and the inclined support 17 can also be formed independently and then assembled into a single unit, all within the scope of this disclosure.
[0071] In this embodiment, the second chassis 16 can be annular, and the outer diameter of the second chassis 16 is larger than the outer diameter of the bottom wall 12, so that the anchor bolt assembly structure 1 has a larger force diffusion area, further improving the load-bearing capacity of the tower section.
[0072] Continue to refer to Figure 4 and Figure 5 The inclined support 17 extends inward from the outer diameter edge of the second chassis 16 toward the outer diameter edge of the bottom wall 12 to provide support between the second chassis 16 and the bottom wall 12.
[0073] Specifically, the included angle α between the inclined support 17 and the bottom wall 12 satisfies 40°≤α≤80°. This facilitates the accumulation and compaction of concrete during the pouring of concrete component 2, prevents air bubbles in concrete component 2, and further improves the load-bearing capacity of the tower section.
[0074] In addition, the diagonal support 17 can also be a convex arc surface structure or a concave arc surface structure, which can be selected according to actual needs, and will not be elaborated here.
[0075] Continue to refer to Figure 1 and Figure 2In order to improve the bonding strength between the bearing component and the concrete component 2, the bearing component also includes a plurality of protruding columns 18, which are disposed on the upper and / or lower side of the bottom wall 12; or, the plurality of protruding columns 18 are disposed on the side of the second chassis 16 facing the bottom wall 12; or, the plurality of protruding columns 18 are disposed on the inner and / or outer wall of the inclined support 17.
[0076] In this embodiment, protruding columns 18 are respectively provided on the bottom wall 12, the second chassis 16 and the inclined support 17. More specifically, protruding columns 18 are provided on the lower wall surface of the bottom wall 12, protruding columns 18 are provided on both side walls of the inclined support 17, and protruding columns 18 are also provided on the top wall surface of the second chassis 16, but this is not a limitation.
[0077] Furthermore, the protruding column 18 has a T-shaped structure, with the small end of the T-shaped structure fixed to the bottom wall 12 and the large end spaced apart from the bottom wall 12; or, the small end of the T-shaped structure is fixed to the second chassis 16 and the large end spaced apart from the second chassis 16; or, the small end of the T-shaped structure is fixed to the diagonal support 17 and the large end spaced apart from the diagonal support 17.
[0078] The anchor bolt assembly structure 1 provided in this embodiment includes a bottom wall 12, an inclined support 17, and a second base 16. The structure is more stable and has a good load-bearing capacity, reducing the leveling steps in the assembly process, thereby further improving the assembly efficiency of the anchor bolt assembly structure 1.
[0079] The tower section provided in this disclosure, by setting a bottom wall 12 at the lower end of the prestressed member 13, makes the multiple prestressed members 13 in the circumferential direction of the tower section more uniformly stressed, which facilitates the diffusion of force within the tower section and improves the crack resistance of the concrete component 2.
[0080] By installing a load-bearing component below the bottom wall 12, the force diffusion performance at the lower end of the prestressed member 13 is further improved, thus enhancing the crack resistance of the tower section. Simultaneously, the load-bearing component facilitates leveling of the anchor bolt assembly structure 1, improving its surface flatness.
[0081] By connecting the top wall 11, bottom wall 12, bearing components and prestressed components 13 into one unit, the structural stability of the tower section is improved, and the displacement of the prestressed components 13 during concrete pouring and vibration is avoided, which can better meet the technical requirements of flatness and position.
