Description

Technical Field

[0001] This invention relates to the field of segmented tower technology, and particularly to a segmented tower with self-positioning docking. Background Technology

[0002] In the field of wind power generation, the tower is a key component supporting the wind turbine generator, and its structural design and installation efficiency directly affect the construction cycle and operating costs of the entire wind power project. Traditional segmented towers typically use a ring-shaped arrangement of multiple segmented units, with each segment requiring connection points in four directions: the two sides for circumferential connection to adjacent segments, and the top and bottom for connection between upper and lower tower sections.

[0003] This design necessitates the creation of numerous bolt holes in each unit section, requiring simultaneous handling of bolts in four directions during installation. This not only increases the number of bolts used but also significantly reduces on-site installation efficiency. More importantly, the multi-connection design inevitably leads to more joint gaps. These gaps can easily cause stress concentration during long-term operation of the wind turbine, while also posing significant challenges to the tower's sealing, affecting the overall structural strength and corrosion resistance of the tower. Furthermore, the structural design of the joints in existing technologies is often quite complex, increasing manufacturing costs and installation difficulty, especially in high-altitude operating environments where installation accuracy is difficult to guarantee, easily leading to joint deviations. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a segmented tower with self-positioning docking capability, comprising a first segment and a second segment. The first segment has a first closing portion, and the second segment has a second closing portion. A connecting hole is provided between the first and second closing portions, and a U-bolt is provided in the connecting hole. After seamless docking, the first and second closing portions are laterally locked by the U-bolt. A tubular reinforcing body is provided on the inner surface of the first closing portion, and a clamping groove is provided on the tubular reinforcing body. A longitudinal locking rod is inserted into the tubular reinforcing body. The closed end of the U-bolt enters the clamping groove and clamps the longitudinal locking rod. The open end of the U-bolt extends into the second segment and is locked by a nut, and a locking channel is provided. An extension rod is inserted into the locking channel. One end of the extension rod is locked in the locking channel by a nut, and the other end is laterally pressed against the second segment.

[0005] As a further preferred embodiment, this application also proposes that the first sheet and the second sheet are semi-circular tubes, the first closure portion is a horizontal plate formed at the maximum diameter of the first sheet, and the second closure portion is a horizontal plate formed at the maximum diameter of the second sheet, so that the first sheet can achieve a large-area seamless connection with the second closure portion of the second sheet through the first closure portion.

[0006] As a further preferred embodiment, this application also proposes that the two sides of the first closed portion and the cavity forming part of the first piece are provided with a first rounded corner, and the two sides of the second closed portion and the cavity forming part of the second piece are provided with a second rounded corner.

[0007] As a further preferred embodiment, this application also proposes that the connecting holes are arranged in two rows, left and right, and are longitudinally opened along the height direction of the first closed portion and the second closed portion, respectively.

[0008] As a further preferred embodiment, this application also proposes that the tubular reinforcement is formed at the middle of the inner surface of the first closure portion, and that the two sides of the tubular reinforcement are provided with a third rounded corner at the connection between the tubular reinforcement and the inner surface of the first closure portion.

[0009] As a further preferred embodiment, this application also proposes that the tubular reinforcement is semi-circular, and its center coincides with the center of the first sheet. The semi-circular outline of the tubular reinforcement protrudes outward away from the inner surface of the first closure portion, and forms a fan-shaped structural cavity with the cavity wall of the first sheet.

[0010] As a further preferred embodiment, this application also proposes that the tubular reinforcement is at the same height as the first closure portion, and that there are several clamping grooves, which are distributed along the height direction of the tubular reinforcement, and each clamping groove is disposed opposite to the two connecting holes on the left and right sides.

[0011] As a further preferred embodiment, this application also proposes that the open end of the U-bolt is provided with a tapered external thread, and the nut is engaged with the open end of the U-bolt through the tapered external thread. The locking groove is a straight groove opened inward from the end of the open end of the U-bolt. When the nut moves linearly along the external thread towards the second closed part, the tapered shape is used to close and lock the locking groove, and the force generated by the closing and locking is used to lock the extension rod.

[0012] As a further preferred embodiment, this application also proposes that the extension rod is a flat tube, and the locking surface shape of the locking groove matches the flat tube.

[0013] The advantages of this invention compared to the prior art are:

[0014] 1. A first closing part and a second closing part are provided at the maximum diameter of the first and second pieces to achieve seamless connection. Two rows of connecting holes are opened on the first closing part and the second closing part, and U-bolts are provided according to the connecting holes. After the first closing part and the second closing part are seamlessly connected, the first and second pieces are laterally locked by U-bolts. The double stud head structure of the U-bolt saves a lot of installation steps compared to cylindrical bolts.

[0015] 2. The seamless connection between the first closed part and the second closed part saves multiple connecting parts on the sheet body. In addition to eliminating a large number of bolt holes, the seamless connection only requires a sealing gasket between the first closed part and the second closed part to complete the sealing treatment. Unlike the existing technology, which requires multiple sealing gaskets for multiple connection positions, thus affecting efficiency.

[0016] 3. The U-bolt, combined with the clamping structure of the longitudinal locking rod and the tubular reinforcement, enables rapid self-positioning installation. It also utilizes the locking point of the closed end of the U-bolt on the longitudinal locking rod to improve the connection strength between the first and second pieces. It has the advantages of reducing the number of bolts, improving installation efficiency, reducing the risk of stress concentration, and enhancing sealing performance.

[0017] 4. The threaded end (open end) of the U-bolt has a locking groove, which transfers the supporting strength of the longitudinal locking rod and the tubular reinforcement to the extension rod, and then from the free end of the extension rod to the first piece. This ensures the strength of both the first and second pieces. Conversely, it ensures the strength of both the second and first pieces. By combining these structures, the U-bolt is used to hold the first and second pieces together through the closed plane between them, which improves assembly efficiency, especially during on-site assembly, which speeds up the construction process.

Detailed Implementation

[0025] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In one implementation, such as Figures 1-6 As shown:

[0027] This embodiment provides a segmented tower with self-positioning docking, including a first segment 1 and a second segment 2. The first segment 1 is provided with a first closing part 3, and the second segment 2 is provided with a second closing part 4. A connecting hole 5 is provided between the first closing part 3 and the second closing part 4. A U-bolt 6 is provided in the connecting hole 5. After the first closing part 3 and the second closing part 4 are seamlessly connected, they are locked laterally by the U-bolt 6. A tubular reinforcing body 7 is provided on the inner surface of the first closing part 3. A clamping groove 8 is provided on the tubular reinforcing body 7. A longitudinal locking rod 9 is inserted in the tubular reinforcing body 7. The closed end of the U-bolt 6 enters the clamping groove 8 to clamp the longitudinal locking rod 9. The open end of the U-bolt 6 extends into the second segment 2 and is locked by a nut 10. A locking groove 11 is provided. An extension rod 12 is inserted in the locking groove 11. One end of the extension rod 12 is locked in the locking groove 11 by the nut 10, and the other end is laterally pushed against the second segment 2.

[0028] Specifically, the first piece 1 and the second piece 2 form a seamless connection through planar contact of the closed portion, eliminating the butt joint seam caused by traditional side connections. After the U-bolt 6 passes laterally through the connecting hole 5, its closed end is embedded in the clamping groove 8 to wrap around the longitudinal locking rod 9, converting the lateral locking force into a circumferential constraint force on the longitudinal locking rod 9, forming a longitudinal rigid support. When the nut 10 is tightened, the tapered external thread 17 at the open end of the U-bolt 6 drives the locking groove 11 to close, and at the same time clamps the extension rod 12 to generate a locking force, making the second piece 2 fit tightly with the first piece 1, while locking the free end of the extension rod 12 onto the second piece 2, so that multiple lateral locking points are formed inside the second piece 2, which is equivalent to forming multiple lateral support skeletons inside the second piece 2, thereby improving the support strength and deformation resistance of the second piece 2. It can also be understood as follows: the longitudinal locking rod 9 is inserted longitudinally into the tubular reinforcement 7, which is also the structure of the first piece 1. In addition to using the tubular reinforcement 7 as the internal radial skeleton support of the first piece 1 to improve the radial strength of the first piece 1, the longitudinal locking rod 9 is also used to improve the longitudinal strength of the first piece 1. Furthermore, the support strength of the longitudinal locking rod 9 and the tubular reinforcement 7 is transferred to the extension rod 12 through the U-bolt with the circumferential feature. The strength is then transferred from the free end of the extension rod 12 to the first piece 1. Thus, in addition to ensuring the strength of the first piece 1, the strength of the second piece 2 is also ensured. At the same time, the strength of the second piece 2 is also ensured. Combining these structures, the first piece 1 and the second piece 2 are held together by the U-bolt through the closed plane between them, which improves the assembly efficiency, especially during on-site assembly, the construction progress is faster.

[0029] Before the first closing part 3 and the second closing part 4 are seamlessly connected, only a sealing gasket needs to be placed between the two to achieve a seal.

[0030] like Figure 6 As shown, in this scheme, the first piece 1 and the second piece 2, in addition to forming the main body of the tower through seamless connection, are also suitable for rapid connection of multi-stage towers in the height direction. It is not necessary to set separate connecting parts at the upper and lower ends of the first piece 1 or the second piece 2. When connecting in the height direction, for example, after raising the first piece 1 relative to the second piece 2, the connecting hole 5 on the first piece 1 is offset upward with the connecting hole 5 on the second piece 2. Then, the connecting hole 5 on the first piece 1 of the second piece is connected with the upwardly offset connecting hole 5 on the second piece 2. Then, U-bolts 6 are inserted into their connecting holes 5 to lock them in the height direction. This method of staggered hole connection is used until the entire tower is assembled, saving a lot of connecting parts and cylindrical bolts.

[0031] Compared to existing technologies, traditional segmented tower structures require connecting parts at four locations on each segment, with each connecting part requiring a separate bolt assembly. This solution, however, achieves docking simply through lateral locking of the closure section, reducing the number of connecting parts. In existing technologies, longitudinal and lateral connecting bolts need to be installed step-by-step. This solution, through the synergistic action of the U-bolt 6 and the longitudinal locking rod 9, achieves simultaneous lateral locking and longitudinal constraint, reducing installation steps. The stepped joints formed by traditional multi-directional connections are prone to leakage paths. This solution's seamless docking structure improves the continuity of the sealing surface, reducing the amount of sealing material used. The combined structure with the longitudinal locking rod 9 creates an internal truss effect, improving the bending resistance of the closure section. It also avoids the increased thickness of the connection section caused by traditional external reinforcing ribs and reduces stress concentration. For seamless docking, only one sealing gasket is needed between the first closure section 3 and the second closure section 4 to complete the sealing process, eliminating the need for multiple sealing gaskets required for multiple connection points, which affects efficiency, as is the case with existing technologies.

[0032] like Figure 3 , Figure 4 As shown, in another embodiment, the first piece 1 and the second piece 2 are semi-circular tubes, the first closing part 3 is a horizontal plate formed at the maximum diameter of the first piece 1, and the second closing part 4 is a horizontal plate formed at the maximum diameter of the second piece 2, so that the first piece 1 can achieve a large-area seamless connection with the second closing part 4 of the second piece 2 through the first closing part.

[0033] A semi-circular tube refers to a tubular structure with a semi-circular cross-section. It can be formed by rolling metal sheets or by casting in a single process. Its symmetrical structure facilitates the formation of a complete circular cross-section when two sheets are joined. Specifically, it can be achieved through casting or welding, where the closure is located at the maximum diameter, maximizing the contact area and reducing the number of joints.

[0034] Specifically, the symmetrical nature of the semi-circular tube allows the two plates (plate 1 and plate 2) to form a complete circular structure without angle adjustment during docking. A horizontal plate is formed at the tube's maximum diameter, ensuring continuous planar contact at the closure point during docking, avoiding the need for multiple independent connection points required in traditional multi-directional connections. Through the large-area contact of the horizontal plate, the load is evenly distributed across the entire mating surface, reducing localized stress concentration and eliminating assembly gaps caused by multiple connection points, thus simplifying the sealing process.

[0035] Compared to existing technologies, traditional segmented tower designs require connection points at four locations on each unit segment, resulting in a large number of cylindrical bolts, low installation efficiency, and significant sealing challenges. This solution, however, utilizes an integrated design of a semi-circular tube and a horizontal plate, requiring only a single closure at the maximum diameter to complete the connection. This reduces the number of connection points and simplifies assembly complexity. It also reduces the number of cylindrical bolts used (one U-bolt is equivalent to two cylindrical bolts, so installing one U-bolt is equivalent to installing two cylindrical bolts in stages), simplifying on-site installation steps and improving assembly efficiency. Furthermore, the large-area seamless connection of the closure reduces the number of connection gaps, simplifies sealing, and improves the overall sealing performance of the tower structure.

[0036] like Figure 1 , Figure 3 As shown, in another embodiment, the two sides of the first closed portion 3 and the cavity forming part of the first piece 1 are provided with a first rounded corner 13, and the two sides of the second closed portion and the cavity forming part of the second piece 2 are provided with a second rounded corner 14.

[0037] Specifically, when a segmented tower is subjected to load, a complex stress distribution occurs at the connection area between the closure and the segmented tube cavity. By transforming the traditional right-angle connection into a rounded transition, stress is uniformly transferred across the curved surface, avoiding localized stress peaks caused by geometric abrupt changes at right angles. During assembly, the continuous curved surface formed by the rounded corner structure guides the uniform distribution of contact pressure and provides a smooth transition contact surface for the filling of sealing material, effectively improving the sealing reliability of the mating joint.

[0038] Compared to existing technologies, the rounded corner design alters the geometry of the connection, dispersing stress that was originally concentrated on the right-angled edges to the curved surface, thus enhancing the structure's fatigue resistance. Furthermore, the continuous curved surface formed by the rounded corners allows the sealant to form a complete annular sealing band during assembly, overcoming the defect of easy breakage of sealing materials at right-angle joints.

[0039] like Figure 1 , Figure 6 As shown, in another embodiment, the connecting holes 5 are arranged in two rows, left and right, and are longitudinally opened along the height direction of the first closed part 3 and the second closed part 4, respectively.

[0040] Among them, the two rows of connecting holes 5 on the left and right refer to the hole structure symmetrically distributed on both sides of the closed part. Specifically, it can be achieved by adopting a double row of holes with equal spacing, forming a bidirectional force support through symmetrical distribution.

[0041] Among them, longitudinal opening in the height direction means that the axis of the hole position is parallel to the vertical extension direction of the closed part.

[0042] Specifically, the two rows of connecting holes 5 on the left and right sides form a symmetrical array of locking points on both sides of the closed section. When the U-bolt is inserted laterally, the symmetrical locking force on both sides produces a balanced clamping effect on the mating surface, preventing displacement caused by unilateral force during the mating process. The longitudinally opened holes extend along the height of the closed section, so that the axial constraint force generated when the bolt is locked covers the entire mating area, enhancing the shear resistance. At the same time, when the cylinder is stacked in the height direction, the two plates are distributed vertically, and their connecting holes 5 are staggered vertically, which facilitates the mating with the plate unit of the upper-level tower body by locking it with the U-bolt insertion holes.

[0043] Compared to existing technologies, traditional segmented tower designs require connection points and multiple sets of bolt holes in four directions, necessitating repeated adjustments to align the holes in multiple directions during installation. This solution, through a symmetrical layout of two rows of longitudinal holes on the left and right sides, concentrates the connection points on both sides of the closure section, reducing the amount of cylindrical bolts used while achieving bidirectional self-positioning and eliminating the assembly complexity caused by multi-directional connections. The multi-hole layout combined with multiple U-bolts for locking avoids seal failure caused by localized stress concentration, thereby improving the overall sealing reliability of the structure.

[0044] In another embodiment, the tubular reinforcement 7 is formed at the middle of the inner surface of the first closed portion 3, and the two sides of the tubular reinforcement 7 are provided with a third rounded corner 15 at the connection between the tubular reinforcement 7 and the inner surface of the first closed portion 3.

[0045] Specifically, the tubular reinforcement 7 is centrally arranged along the axis of the closure, and its symmetrical structure allows the butt load to be evenly distributed to both sides of the plate. When an external load is applied to the closure, the tubular reinforcement 7 resists bending deformation through axial stiffness, while the third fillet 15 allows stress to diffuse smoothly along the arc surface, avoiding peak stress at the right-angle connection. During assembly, after the longitudinal locking rod 9 is inserted into the tubular reinforcement 7, the third fillet 15 also reduces the local stress in the contact area between the locking rod and the closure.

[0046] like Figures 1 to 4 As shown, in another embodiment, the tubular reinforcement 7 is semi-circular, and its center coincides with the center of the first piece 1. The semi-circular outline of the tubular reinforcement 7 protrudes outward away from the inner surface of the first closure portion 3, and forms a fan-shaped structural cavity 16 between it and the cavity wall of the first piece 1.

[0047] Specifically, when the two plates are joined through the closure, the semi-circular tubular reinforcement 7 is arranged concentrically with the tower, ensuring that the constraint force of the longitudinal locking rod 9 is evenly distributed circumferentially. When subjected to lateral locking force, the outwardly protruding semi-circular contour transforms concentrated stress into circumferential tensile stress through its arc-shaped structure. The presence of the fan-shaped cavity 16 creates a triangular support structure between the reinforcement and the inner wall of the tower. During bolt pre-tightening, this cavity guides stress to be dispersed and transmitted along the arc surfaces on both sides of the tubular reinforcement 7. This integrated structural design allows a single reinforcement to simultaneously perform both longitudinal constraint and lateral support functions, eliminating the need for additional independent connecting components.

[0048] Compared to existing technologies, traditional segmented tower structures require separate bolt holes and connecting plates at each connection point, leading to complex assembly processes and an increase in sealing surfaces. This solution, through geometric optimization of the tubular reinforcement 7, integrates longitudinal locking and lateral support functions into a single structure, reducing the number of connection points by approximately 50%. In existing technologies, the stepped joints formed by multiple independent connecting plates are prone to leakage risks, while the smooth transition surface formed by the continuous semi-circular structure in this solution significantly reduces sealing difficulty.

[0049] like Figure 3 , Figure 4 As shown, in another embodiment, the tubular reinforcement 7 is at the same height as the first closing part 3, and there are several clamping grooves 8. The several clamping grooves 8 are distributed along the height direction of the tubular reinforcement 7, and each clamping groove 8 is disposed opposite to the two connecting holes 5 on the left and right.

[0050] Specifically, when the closed end of the U-bolt is embedded in the clamping groove 8, its open end passes through the connecting hole 5 and is locked by the nut 10. At this time, the longitudinal locking rod 9 is wrapped by the tubular reinforcement 7, and the clamping groove 8 forms a longitudinal constraint on the U-bolt. Since the clamping grooves 8 are equidistantly distributed along the height direction of the tubular reinforcement 7, and each groove is directly opposite the central area between the left and right connecting holes 5, the tensile force generated during the lateral locking process is transmitted to the longitudinal locking rod 9 through the U-bolt, forming a composite constraint of lateral and longitudinal forces. This layout allows a single connecting hole 5 to complete both lateral bolt locking and longitudinal force transmission through the clamping groove 8, thereby reducing the number of independent connection parts.

[0051] Compared to existing technologies, traditional segmented tower structures require connecting parts in four directions and multiple sets of bolts. This solution, however, integrates the longitudinal locking function into the transverse connection structure through the coordinated layout of the clamping grooves 8 and connecting holes 5. In existing technologies, each connecting part requires a separate bolt hole and fastener installation. This solution, through the longitudinal distribution of the clamping grooves 8, allows a single row of connecting holes 5 to simultaneously bear both transverse and longitudinal loads, reducing the amount of bolts used and the installation process.

[0052] like Figure 2 , Figure 5As shown, in another embodiment, the open end of the U-bolt 6 is provided with a tapered external thread 17. The nut 10 is fitted onto the open end of the U-bolt 6 through the tapered external thread 17. The locking groove 11 is a straight groove opened inward from the end of the open end of the U-bolt 6. When the nut 10 moves linearly along the external thread 17 toward the second closed part 4, the tapered shape is used to close and lock the locking groove, and the force generated by the closing and locking is used to lock the extension rod 12.

[0053] The tapered external thread 17 refers to a thread structure where the outer diameter of the thread gradually changes along the axial direction. Specifically, it can be achieved using a thread parameter with a taper of 1:16, generating radial contraction force through the tapered surface fit. The locking groove 11 is a through groove opened along the bolt axis. Specifically, it can be formed by wire cutting to create a straight groove structure with a width of 2mm, providing directional guidance for deformation closure. The extension rod 12 is a rigid rod with a flat cross-section, specifically implemented using a rectangular steel tube with a wall thickness of 3mm. Its lateral pressing effect can disperse stress concentration at the connection point.

[0054] Specifically, when the nut 10 is screwed into the closed portion along the tapered external thread 17, the tapered surface engagement forces the open end to undergo radial contraction deformation, causing the locking groove 11 to close and clamp the extension rod 12. During this process, the axial movement of the nut 10 is converted into radial deformation of the locking groove 11, firmly fixing the extension rod 12 within the closed groove. Simultaneously, the lateral pressure of the extension rod 12 forms a self-balancing structure through the reaction force of the second plate 2, effectively reducing shear stress at the connection point and ensuring that the cavity of the second plate 2 remains undeformed. Furthermore, during installation, one end of the extension rod 12 is first inserted into the unlocked locking groove, and the free end of the extension rod 12 presses against the cavity wall of the second plate 2. The nut 10 then locks the U-bolt 6, simultaneously locking the first closed portion 3 and the second closed portion 4 (the two plates are tightly bound together) and simultaneously securing the extension rod 12, improving work efficiency.
