Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower installation foundations, specifically to a wind turbine tower reinforcement device. Background Technology

[0002] In the field of wind power generation, the wind turbine tower is an important supporting structure for wind turbine generators, and its stability and safety are of paramount importance. The main materials used for wind turbine towers are high-strength steel or aluminum alloys to ensure sufficient strength and optimized weight ratio.

[0003] During operation, the vibrations caused by the rotation of the turbine blades and wind loads are transmitted downwards through the tower. If the tower's stiffness is insufficient or its damping is inadequate, these vibrations are easily amplified in the upper and middle parts of the tower, causing vibrations in the top turbine. Continuous vibration increases the fatigue stress on the tower material, which may lead to fatigue cracks or even failure in the long run. At the same time, vibration may also cause excessive lateral swaying or deformation of the tower.

[0004] In related technologies, the strength and rigidity of the tower structure are often improved by simply increasing the thickness of the tower wall or internal support. However, the actual cost is high, the weight increases significantly, and the effect on suppressing vibration in a specific direction is limited. Simple ground anchors cannot effectively resist dynamic multi-directional pull-out forces. Utility Model Content

[0005] In view of this, the present invention provides a wind turbine tower reinforcement device to solve the problems mentioned in the background art.

[0006] In a first aspect, this utility model provides a wind turbine tower reinforcement device, comprising:

[0007] The sleeve assembly includes a connecting ring plate, a bolt structure, and a collar; multiple sets of connecting ring plates are provided, and the multiple sets of connecting ring plates are together encircling the outer surface of the wind turbine tower; the bolt structure penetrates and connects two adjacent connecting ring plates, fixing the multiple sets of connecting ring plates to the wind turbine tower; the collar is rotatably sleeved on the bolt structure, and the collar is disposed between two adjacent connecting ring plates;

[0008] The inclined cable reinforcement component and the fixing component are provided. The upper end of the inclined cable reinforcement component is fixedly connected to the collar, and the lower end of the inclined cable reinforcement component is fixedly connected to the fixing component. The fixing component is adapted to be fixed to the ground side.

[0009] The inclined cable reinforcement component transmits the vibration energy of the wind turbine tower to the ground side.

[0010] Beneficial effects: By using a sleeved assembly to encircle the wind turbine tower, the inclined cable reinforcement assembly connects to the upper sleeve and the lower fixed assembly on the ground side to transfer vibration energy to the ground side. The inclined cable assembly forms a rigid support, which, when sleeved on the upper part of the tower, enhances the lateral stiffness of the upper part of the tower, suppresses vibration amplification, and effectively overcomes the defect of insufficient stiffness. The rotatable design of the sleeve optimizes the dynamic adaptability of force transmission, preventing the inclined cables from being rigidly pulled apart due to slight deformation of the tower. It directs vibration energy to the ground, reducing the fatigue stress on the tower, lowering the fatigue risk, and preventing cracks. The wind turbine tower reinforcement device provided in this application can effectively resist dynamic multi-directional pull-out forces. Furthermore, compared to traditional technologies that increase wall thickness or internal support, external reinforcement helps to reduce material costs and optimize the tower's self-weight.

[0011] In some embodiments, the fixing component includes:

[0012] A fixing plate that fits against the ground side, wherein a first mounting hole and a second mounting hole are provided through the fixing plate; the first mounting hole is arranged in the vertical direction, and the second mounting hole is arranged at an angle to the vertical direction;

[0013] The first rivet is anchored into the ground side, and the first rivet is vertically inserted into the first mounting hole. The side wall of the first rivet is provided with an oblique hole.

[0014] A second rivet is inserted at an angle into the second mounting hole and anchored into the ground side, the second rivet passing through the angled hole;

[0015] The first rivet and the second rivet form a cross anchoring structure.

[0016] Beneficial effects: A vertical first mounting hole and an inclined second mounting hole are provided on the fixing plate. The first rivet is directly anchored vertically, and the second rivet passes through the inclined hole at an angle to form a cross anchorage. The cross anchorage structure effectively decomposes horizontal and inclined pull-out forces and effectively resists dynamic multi-directional pull-out forces. Furthermore, the second rivet passes through the inclined hole of the first rivet, forming a mechanical interlock to prevent the anchor from coming loose when the soil is loose.

[0017] In some embodiments, the cable-stayed reinforcement assembly includes:

[0018] Two sets of cable components, each set of cable components includes a stay cable, a limiting plate and a threaded rod. The stay cable and the threaded rod are fixedly installed on both sides of the limiting plate. The upper end of the stay cable of one set of cable components is fixedly installed with the collar, and the lower end of the stay cable of the other set of cable components is fixedly installed with the fixing plate. The threaded rod is installed on the opposite side of the two sets of cable components.

[0019] An adjusting frame is connected between two sets of cable components. The adjusting frame has threaded portions at both ends along its length, and the threaded portions are threadedly sleeved on the end of the threaded rod away from the limiting plate.

[0020] Beneficial effects: The cable-stayed reinforcement component includes two sets of cable components and an adjustment frame. Specifically, the threaded rod and the threaded part of the adjustment frame are engaged to adjust the overall length of the cable-stayed reinforcement component and the preload of the two sets of cable components, so as to reasonably adjust the structural stiffness and suppress vibration. In actual construction, on-site adjustment can compensate for installation errors or foundation deformation to maintain the optimal tension state. This threaded engagement is conducive to modular maintenance, and a single set of cables can be replaced independently when damaged, reducing maintenance costs.

[0021] In some embodiments, a groove is provided on the outer surface of the first rivet, and a ridge is provided on the inner wall of the first mounting hole. The groove and the ridge fit together to limit the insertion angle of the first rivet, so that the oblique hole is aligned with the second mounting hole.

[0022] Beneficial effects: The groove on the first rivet engages with the protrusion on the fixing plate to constrain the oblique hole to align with the second mounting hole, ensuring the desired insertion angle; mechanical limiting ensures that the oblique hole and the second mounting hole are forcibly aligned, improving assembly accuracy; and the foolproof design eliminates the need for users to repeatedly adjust the angle, thus improving construction efficiency and shortening installation time.

[0023] In some embodiments, the upper surface of the fixing plate has two inclined structures. The inclined cable is fixed to the inclined structure near the wind turbine tower. The second mounting hole is inclinedly disposed on the other inclined structure, and the inclination direction of the second mounting hole corresponds to the insertion direction of the second rivet.

[0024] Beneficial effects: The fixing plate is equipped with two inclined structures. The inclined cable is connected to the inclined surface near the inner side of the wind turbine tower, and the second rivet is connected to the inclined surface on the outer side. By optimizing the structural connection layout, stress concentration that could lead to deformation of the fixing plate can be avoided. This separation of the inclined cable and the anchor point can also avoid operational interference and facilitate on-site operation. The two inclined structures can ensure that the cable tension and the rivet anchoring force are intersected, improving the effect of vibration suppression and fixing.

[0025] In some embodiments, the adjusting frame is configured as a hollow cylindrical structure with internal threads, and its two ends are respectively threaded into two threaded rods; when the adjusting frame is rotated, the two sets of cable components are adapted to move synchronously closer or further apart.

[0026] Beneficial effects: The adjusting frame is a hollow threaded cylinder, which drives the threaded rods on both sides to move synchronously when rotated; this method can ensure the tension of the cables on both sides is balanced, achieving a symmetrical tensioning effect. Both sides can be adjusted in a single operation, making it highly efficient and suitable for high-altitude operations.

[0027] In some embodiments, the limiting plate is configured as a circular plate structure, the diameter of which is larger than the diameter of the hollow cylindrical structure.

[0028] Beneficial effect: The limiting plate mechanically stops the adjusting bracket to limit excessive screwing and prevent thread stripping failure.

[0029] In some embodiments, the groove extends axially along the first rivet, and the protrusion extends axially along the first mounting hole, the two together forming a circumferential limiting structure.

[0030] Beneficial effects: The groove and the convex strip extend axially to form a circumferential limiting structure; this design can prevent the first rivet from rotating and suppress rotational loosening under tower vibration environment, and ensure that the anchoring angle of the cross rivets is stable, thereby ensuring reliable and effective anchoring and diagonal support.

[0031] In some embodiments, four sets of the inclined cable reinforcement components and the fixing components are provided corresponding to each other, and the four sets of the inclined cable reinforcement components and the fixing components are distributed in a ring on the outer periphery of the wind turbine tower.

[0032] Beneficial effects: The four sets of inclined cable components are evenly distributed in a ring around the outer perimeter of the tower to cover the vibration components in multiple directions and prevent the tower from lateral swaying or deformation; at the same time, it can promote the balanced transmission of vibration load, avoid local stress concentration, and extend the service life of the tower.

[0033] In some embodiments, the two ends of the connecting ring plate are provided with connecting ears, the bolt structure includes a bolt and a nut, the bolt is inserted through the connecting ears, the nut is threadedly locked with the bolt to fix the two adjacent connecting ring plates, and the collar is rotatably sleeved on the bolt.

[0034] Beneficial effects: The connecting lugs, bolts, and nuts lock two adjacent connecting ring plates together, thereby locking multiple sets of connecting ring plates onto the tower. This quick assembly and disassembly method, through the connection and combination of multiple sets of connecting ring plates and bolt structures, can adapt to towers of different diameters and is easy to adjust and assemble. By rotating the collar to engage the bolts, the slight displacement caused by thermal expansion and contraction or vibration of the tower can be released, playing a dynamic compensation role and enhancing the adaptation and fixing effect on wind turbine towers.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The purpose of this invention is to efficiently guide and disperse the vibration energy of the upper part of the tower to the ground anchor points using an adjustable tension cable system, while greatly enhancing the pull-out resistance of the ground anchor points through an innovative cross-anchoring structure, thus forming a dynamically stable "cable-stayed bridge" type reinforcement system.

[0045] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a wind turbine tower reinforcement device is provided, which includes a sleeve assembly, a diagonal bracing reinforcement assembly 5, and a fixing assembly 6.

[0047] See Figure 1 and Figure 2 The sleeve assembly includes a connecting ring plate 2, a bolt structure 3, and a collar 4. Multiple sets of connecting ring plates 2 are provided, and the multiple sets of connecting ring plates 2 are arranged together around the outer surface of the wind turbine tower 1. The bolt structure 3 passes through and connects two adjacent connecting ring plates 2, fixing the multiple sets of connecting ring plates 2 to the wind turbine tower 1. The collar 4 is rotatably sleeved on the bolt structure 3 and is arranged between two adjacent connecting ring plates 2.

[0048] The upper end of the inclined cable reinforcement component 5 is fixedly connected to the collar 4, and the lower end of the inclined cable reinforcement component 5 is fixedly connected to the fixing component 6. The fixing component 6 is suitable for fixing to the ground side. The inclined cable reinforcement component 5 transmits the vibration energy of the wind turbine tower 1 to the ground side.

[0049] The wind turbine tower reinforcement device provided in this embodiment uses a sleeve assembly to encircle the wind turbine tower 1. The inclined reinforcement assembly 5 is connected to a collar 4 on the upper side and a fixed assembly 6 on the ground side on the lower side to transfer vibration energy to the ground side. The inclined assembly forms a rigid support. When sleeved on the upper part of the tower, it can enhance the lateral stiffness of the upper part of the tower, suppress vibration amplification, and effectively overcome the defect of insufficient stiffness. The rotatable design of the collar 4 optimizes the dynamic adaptability of force transmission, which can prevent the inclined cable 501 from being rigidly pulled and broken due to micro-deformation of the tower. It guides the vibration energy to the ground, reduces the fatigue stress on the tower, reduces the fatigue risk, and avoids cracks.

[0050] The wind turbine tower reinforcement device provided in this embodiment can effectively resist dynamic multi-directional pull-out forces; and compared with the traditional technology of increasing wall thickness or internal support, external reinforcement is conducive to reducing material costs and optimizing the self-weight of the tower.

[0051] In some embodiments, see Figure 1 and Figure 2 The connecting ring plate 2 has connecting ears protruding from both ends. The bolt structure 3 includes a bolt and a nut. The bolt passes through the connecting ears, and the nut and bolt are threaded together to lock the two adjacent connecting ring plates 2. The collar 4 is rotatably fitted onto the bolt. The collar 4 has an axial cavity for the bolt to pass through.

[0052] Two adjacent connecting ring plates 2 are locked together by connecting lugs, bolts, and nuts to lock multiple sets of connecting ring plates 2 onto the tower. This quick assembly and disassembly method, through the connection and combination of multiple sets of connecting ring plates 2 and bolt structure 3, can adapt to towers of different diameters and is easy to adjust and assemble. By rotating the collar 4 to engage the bolts, the slight displacement caused by thermal expansion and contraction or vibration of the tower can be released, which plays a dynamic compensation role and enhances the adaptation and fixing effect of the wind turbine tower 1.

[0053] In some embodiments, see Figure 4 The fixing component 6 includes a fixing plate 601, a first rivet 604, and a second rivet 606; the first rivet 604 and the second rivet 606 form a cross-anchoring structure. The cross-anchoring structure effectively decomposes horizontal and oblique pull-out forces and effectively resists dynamic multi-directional pull-out forces.

[0054] Specifically, see Figure 3 and Figure 4 The fixing plate 601 is attached to the ground side, and the fixing plate 601 is provided with a first mounting hole 602 and a second mounting hole 603; the first mounting hole 602 is set in the vertical direction, and the second mounting hole 603 is set at an angle to the vertical direction.

[0055] Specifically, both the first rivet 604 and the second rivet 606 are anchored into the ground side. The first rivet 604 is vertically inserted into the first mounting hole 602, and the side wall of the first rivet 604 is provided with an oblique hole 605. The second rivet 606 is obliquely inserted into the second mounting hole 603, and the second rivet 606 passes through the oblique hole 605.

[0056] By providing a vertical first mounting hole 602 and an inclined second mounting hole 603 on the fixing plate 601, the first rivet 604 is directly and vertically anchored in, and the second rivet 606 is inclined through the inclined hole 605 to form a cross anchoring. Furthermore, the second rivet 606 passes through the inclined hole 605 of the first rivet 604, forming a mechanical interlock to prevent the anchor from coming loose when the soil is loose.

[0057] In some embodiments, see Figure 2 and Figure 3 The cable-stayed reinforcement component 5 includes cable members and an adjustment frame 504; the cable members are provided in two sets, and the adjustment frame 504 is connected between the two sets of cable members.

[0058] Specifically, see Figures 3 to 5Each set of cable components includes a stay cable 501, a limiting plate 502, and a threaded rod 503. The stay cable 501 and the threaded rod 503 are fixedly installed on both sides of the limiting plate 502. The upper end of the stay cable 501 of one set of cable components is fixedly installed with the collar 4, and the lower end of the stay cable 501 of the other set of cable components is fixedly installed with the fixing plate 601. The threaded rod 503 is installed on the opposite side of the two sets of cable components. The adjusting frame 504 has threaded parts at both ends along its length direction. The threaded parts are threadedly sleeved on the end of the threaded rod 503 away from the limiting plate 502.

[0059] The threaded rod 503 engages with the threaded part of the adjusting frame 504 to adjust the overall length of the cable reinforcement component 5 and the preload of the two sets of cable components, thereby reasonably adjusting the structural stiffness and suppressing vibration. In actual construction, on-site adjustment can compensate for installation errors or foundation deformation to maintain the optimal tension state. This threaded engagement is conducive to modular maintenance, and a single set of cables can be replaced independently when damaged, reducing maintenance costs.

[0060] In some embodiments, see Figure 4 The outer surface of the first rivet 604 is provided with a groove, and the inner wall of the first mounting hole 602 is provided with a protrusion. The groove and the protrusion fit together to limit the insertion angle of the first rivet 604, so that the oblique hole 605 is aligned with the second mounting hole 603.

[0061] By engaging the groove on the first rivet 604 with the protrusion on the fixing plate 601, the oblique hole 605 can be constrained to align with the second mounting hole 603, ensuring the desired insertion angle; mechanical limiting ensures that the oblique hole 605 and the second mounting hole 603 are forcibly aligned, improving assembly accuracy; a foolproof design is established, so users do not need to repeatedly adjust the angle, which helps to improve construction efficiency and shorten installation time.

[0062] In some embodiments, see Figure 4 The upper surface of the fixing plate 601 has two inclined structures. The stay cable 501 is fixed to the inclined structure near the wind turbine tower 1, and the second mounting hole 603 is inclinedly set on the other inclined structure, with the inclination direction of the second mounting hole 603 corresponding to the insertion direction of the second rivet 606. By setting two inclined structures on the fixing plate 601, with the stay cable 501 connected to the inclined structure near the inner side of the wind turbine tower 1 and the second rivet 606 connected to the outer inclined structure, the optimized structural connection layout avoids stress concentration that could lead to deformation of the fixing plate 601. This separation of the stay cable 501 from the anchor point also avoids operational interference and facilitates on-site operation. The two inclined structures ensure that the cable tension and the rivet anchoring force are intersected, improving vibration suppression and fixation effectiveness.

[0063] In some embodiments, see Figure 5The adjusting frame 504 is configured as a hollow cylindrical structure with internal threads, and its two ends are respectively threaded with two threaded rods 503; when the adjusting frame 504 is rotated, the two sets of cable components are adapted to move synchronously closer or further away.

[0064] The adjusting frame 504 is a hollow threaded cylinder that drives the threaded rods 503 on both sides to move synchronously when rotated. This method can ensure the tension of the cables on both sides is balanced, achieving a symmetrical tensioning effect. Both sides can be adjusted in a single operation, making it highly efficient and suitable for high-altitude operations.

[0065] In a further embodiment, the limiting plate 502 is configured as a circular plate structure, the diameter of which is larger than the diameter of the hollow cylindrical structure. The limiting plate 502 mechanically stops the adjusting frame 504 to limit excessive screwing and prevent thread stripping failure.

[0066] In some embodiments, see Figure 4 The groove extends axially along the first rivet 604, and the ridge extends axially along the first mounting hole 602, together forming a circumferential limiting structure. Extending the groove and ridge axially to form a circumferential limiting structure prevents the first rivet 604 from rotating under tower vibration conditions, suppresses rotational loosening, and ensures the stability of the cross rivet anchoring angle, thereby guaranteeing reliable and effective anchoring and diagonal support.

[0067] In a specific embodiment, four sets of inclined bracing components 5 and fixing components 6 are provided correspondingly, and the four sets of inclined bracing components 5 and fixing components 6 are distributed in a ring around the outer periphery of the wind turbine tower 1. The four sets of inclined bracing components are evenly distributed in a ring around the outer periphery of the tower to cover the vibration components in multiple directions and avoid lateral swaying or deformation of the tower; at the same time, it can promote the balanced transmission of vibration load, avoid local stress concentration, and extend the service life of the tower.

[0068] The wind turbine tower reinforcement device provided in this embodiment, through the cooperation of the inclined reinforcement component 5 and the fixing component 6, forms an inclined structure between the wind turbine tower 1 and the ground, which can effectively disperse the vibration energy at the top of the tower, enhance the overall stability of the tower, reduce stress concentration at the bottom of the tower, and reduce the risk of tower tilting or collapse; the cable assembly and the adjusting frame 504 provide adjustable tension to ensure that the tower is subjected to uniform force under different working conditions, avoid excessive stress at the bottom, and extend the service life of the tower; the first rivet 604 and the second rivet 606 form a cross anchoring structure in the soil layer on the ground side, providing stronger fixing force and ensuring the stability of the device under complex terrain and extreme weather conditions.

[0069] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
