Description

Technical Field

[0001] This invention relates to the field of wind turbine towers, and in particular to a segmented anti-vibration reinforcement support device for wind turbine towers. Background Technology

[0002] As the core supporting structure of a wind power generation system, the stability of the wind turbine tower directly affects the safe operation and power generation efficiency of the entire generator set. These towering towers are usually made of steel cylindrical or conical structures, reaching heights of tens or even hundreds of meters, with the heavy nacelle, generator, and rotating blades on top. Serving in complex outdoor environments for extended periods, the towers not only have to withstand the enormous static loads of themselves and the upper equipment, but also cope with the dynamic excitations generated by natural winds and turbine operation. As the wind power industry develops towards larger scale and higher efficiency, the height and flexibility of the towers are constantly increasing, making their vibration problems under dynamic loads increasingly prominent and a key factor that must be considered during design. The importance of vibration-resistant reinforcement for wind turbine towers is self-evident, primarily aimed at ensuring structural safety and extending service life. Wind loads, turbine operation, especially blade rotation, and dynamic forces such as earthquakes can induce various forms of vibration in the tower, including overall swaying and localized bending vibrations. These continuous vibrations can lead to fatigue damage in the tower structure, particularly in critical areas such as the tower root and connecting flanges. Accumulated stress may eventually cause weld cracking or component failure, and in severe cases, even tower overturning. Furthermore, excessive vibration can affect the alignment accuracy of the top generator, reduce power generation efficiency, and increase maintenance costs. Therefore, taking effective vibration-resistant measures to suppress vibration amplitude and dissipate vibration energy is crucial for ensuring the safe and reliable operation of wind turbine towers throughout their entire life cycle. However, existing wind turbine tower support and vibration damping technologies still have some obvious limitations. Traditional support methods mostly focus on rigid connections of the foundation or single damping elements, which are often unable to cope with the differentiated vibration characteristics of different sections of the tower. A common drawback is that the damping mechanism is concentrated in the lower part, which is not effective in controlling the sway of the upper part of tall towers and may lead to stress concentration in specific areas. On the other hand, some complex vibration damping devices are expensive to manufacture and are not convenient for rapid on-site installation and subsequent maintenance, which to some extent limits their widespread application. To address this, a segmented vibration damping and reinforcement support device for wind turbine towers is proposed. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a segmented vibration-resistant reinforcement support device for wind turbine towers. This device effectively addresses issues such as concentrated vibration-resistant functions, uneven stress distribution, and difficult installation and maintenance in the prior art through an innovative segmented vibration-resistant structure and multi-stage energy dissipation mechanism. Specifically, the device achieves segmented dissipation and coordinated control of vibration energy by setting up first, second, and third buffer components for vibrations in the lower, middle, and leg sections of the tower, respectively. The modular connecting strips and flanges of the support components simplify the on-site installation process. Furthermore, the use of reinforcement frames and ribs enhances overall stability. This device not only effectively suppresses multi-frequency vibrations of the tower under different operating conditions but also adapts to complex terrain and long-term use requirements through adjustable anchoring structures and standardized interfaces, effectively solving the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a segmented anti-vibration reinforcement support device for wind turbine towers, comprising tower legs and a first buffer assembly; Tower legs: There are four, and a reinforcing frame is fixed on the side of each tower leg. A support component is installed on the upper side of each of the four tower legs. A connecting component is installed on the upper side of each support component. A second buffer component is installed on the support component and the side of each of the four tower legs. Four corresponding third buffer components are installed between the four tower legs. The first buffer assembly comprises a support plate, an inclined block, a fixed barrel, a sliding rod, a damping disc, a first spring, and a connecting frame. Two corresponding support plates are fixed to the side of the reinforcing frame. An inclined block is fixed to the side of the support plate. A fixed barrel is hinged to the side of the inclined block. A sliding rod is slidably connected inside the fixed barrel. A damping disc is fixed to the end face of the sliding rod and slidably connected inside the fixed barrel. A first spring is fixed to the end face of the damping disc, and the other end of the first spring is fixed inside the fixed barrel. Two corresponding connecting frames are fixed to the side of the reinforcing frame. The end of the sliding rod away from the damping disc is hinged to the inside of the corresponding connecting frame. Stable support is provided by four tower legs. The first buffer assembly absorbs the initial energy from foundation vibration and wind load by utilizing the sliding friction of the spring and the damping disc, reducing stress concentration at the tower root.

[0005] Furthermore, the support assembly includes connecting strips and connecting flanges. Connecting strips are provided on the upper side of the tower legs. Four connecting strips are connected to four tower legs through four connecting flanges. Modular assembly is achieved through connecting strips and connecting flanges, which facilitates transportation and on-site installation. The connecting flanges provide a high-strength rigid connection to ensure the integrity of the tower under wind load, while also providing an installation foundation for the upper second buffer assembly.

[0006] Furthermore, the second buffer assembly includes a T-shaped groove, a sliding frame, an arc-shaped plate, a connecting column, and a second spring. Two corresponding arc-shaped plates are provided on the side of the connecting strip. Two corresponding connecting columns are fixed to the upper and lower sides of the arc-shaped plates. Two corresponding sliding frames are provided at the upper and lower ends of the arc-shaped plates. The connecting columns are rotatably connected to the interior of the corresponding sliding frames. Two corresponding T-shaped grooves are opened on the sides of the tower legs and the connecting strip. All sliding frames are slidably connected to the interior of the corresponding T-shaped grooves. A second spring is fixed to the side of the sliding frame and is fixed inside the T-shaped groove. The arc-shaped plate slides within the T-shaped groove through the sliding frame. Combined with the elastic deformation of the second spring, the arc-shaped plate is allowed to undergo slight displacement under wind load, thereby consuming the tower's swaying energy. The rotatable connection of the connecting column avoids rigid constraints, achieving flexible buffering and reducing the risk of localized fatigue in the tower.

[0007] Furthermore, the third buffer assembly includes T-shaped brackets, connecting columns, and rubber heads. Four corresponding T-shaped brackets are fixed between the four tower legs. Two corresponding connecting columns are fixed on the side of each T-shaped bracket. Rubber heads are fixed on the end faces of the connecting columns. All rubber heads are respectively attached to the sides of the four connecting strips. The third buffer assembly is used to suppress the relative displacement and vibration transmission between the tower legs. The T-shaped brackets provide lateral support. The rubber heads are attached to the connecting strips and absorb high-frequency vibration energy through the elastic deformation of the rubber, preventing resonance between the legs and enhancing the stability of the device under extreme weather conditions.

[0008] Furthermore, the connecting assembly includes connecting blocks, connecting discs, and connecting grooves. A connecting block is fixed to the upper side of the connecting strip, and a connecting disc is fixed between the four connecting blocks. A connecting groove is provided at the upper end of the connecting disc. The connecting assembly serves as the interface between the tower and the upper wind turbine equipment. The connecting disc and connecting groove enable quick alignment and installation. The connecting block distributes the upper load to the connecting strip, reducing stress concentration and ensuring a stable connection of the tower top during unit operation.

[0009] Furthermore, a connecting ring is fixed to the circumference of the connecting plate, and the upper end of the connecting ring has evenly distributed connecting holes. The connecting ring and connecting holes provide additional mounting points for fixing cables or auxiliary equipment, preventing cable tangling and wind-induced wear. The evenly distributed connecting holes facilitate adjustment of the installation position, improving the practicality and maintainability of the device.

[0010] Furthermore, the support plate has a threaded groove on its lower side, and a threaded post is threadedly connected inside the threaded groove. A tapered fixing post is fixed at the lower end of the threaded post. The threaded post and the tapered fixing post allow the device to be deeply anchored to the foundation. The tapered design enhances pull-out resistance and prevents foundation slippage, making it suitable for soft soil or mountainous environments.

[0011] Furthermore, the upper side of the support plate is provided with four corresponding fixing holes, and a reinforcing ring is fixed inside the fixing hole. The reinforcing ring is embedded in the fixing hole to increase the local stiffness and compressive strength of the support plate, prevent deformation under long-term load, and extend the service life of the first buffer assembly.

[0012] Furthermore, evenly distributed reinforcing ribs are fixed to the sides of the four tower legs, and reinforcing frames are fixed to the sides of the four tower legs. The reinforcing ribs and reinforcing frames form a mesh support structure, which improves the bending and torsional resistance of the tower legs, reduces lateral deformation caused by wind load, and ensures the structural integrity of the device under strong winds.

[0013] Furthermore, a locking post is fixed to the lower side of the connecting strip, and a locking groove is opened on the upper side of the tower leg. The locking post is engaged inside the corresponding locking groove. The locking design of the locking post and the locking groove enables quick positioning and pre-installation, avoids displacement of the connecting strip during hoisting, improves assembly efficiency, and provides additional shear resistance, enhancing the reliability of the connection between the support component and the leg.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This segmented vibration-resistant reinforcement and support device for wind turbine towers has the following advantages: 1. Through the hinged design of the inclined block and the fixed barrel in the first buffer assembly, combined with the sliding of the slide rod in the fixed barrel and the synergistic effect of the damping disc and the first spring, the device can flexibly cope with vibration impacts from different directions. This multi-directional buffer mechanism can not only effectively absorb the vibration energy transmitted from the foundation and the initial energy of the wind load, but more importantly, it avoids the stress concentration phenomenon generated at the root of the tower by allowing small displacements and rotations, thereby significantly reducing the risk of structural fatigue damage. 2. The second buffer assembly forms a unique flexible constraint system in the upper part of the tower through the ingenious combination of the arc-shaped plate, connecting column and sliding frame. The arc-shaped plate slides in the T-shaped groove through the sliding frame, and with the help of the elastic restoring force of the second spring, the constraint force is not rigid but flexible. When the tower bends or swings, this assembly allows the arc-shaped plate to produce a small displacement, and consumes the swing kinetic energy through friction and spring deformation, thereby effectively suppressing the harmful vibration of the upper part of the tower and avoiding the risk of local buckling. 3. The third buffer component works in conjunction with the reinforcing frame, reinforcing ribs, and other structures to greatly improve the overall stability of the support device; the T-shaped bracket and the connecting column with rubber head form a lateral support between the legs, and the elastic deformation of the rubber material can effectively absorb high-frequency vibration energy, block the transmission path of vibration between the legs, and prevent adverse resonance effects; at the same time, the mesh support structure composed of the reinforcing frame and reinforcing ribs significantly enhances the bending and torsional resistance of the tower legs, ensuring that the entire support system maintains geometric stability and structural integrity under extreme loads such as strong winds; 4. The modular design concept of this device is implemented throughout, bringing significant engineering convenience; the support components and tower legs are quickly positioned and firmly connected through the cooperation of connecting flanges and clamps and slots, which greatly simplifies the on-site hoisting and assembly process and improves installation accuracy and efficiency; this split design also effectively overcomes the limitations of transporting large-sized components; in addition, the clear modular division facilitates subsequent inspection, maintenance or partial replacement, reduces the maintenance cost throughout the entire life cycle, and demonstrates excellent engineering applicability; Attached Figure Description

[0022] Please see Figure 1-5This embodiment provides a technical solution: a segmented anti-vibration reinforcement support device for wind power towers, including tower legs 1 and a first buffer assembly 3; Tower legs 1: Four are provided.

An arc-shaped plate 53 has two corresponding connecting columns 54 fixed on its upper and lower sides. Two corresponding sliding brackets 52 are provided at the upper and lower ends of the arc-shaped plate 53. The connecting columns 54 are rotatably connected to the interior of the corresponding sliding brackets 52.

A second spring 55 is fixed on the side of the sliding bracket 52 and is fixed inside the T-shaped groove 51. The third buffer assembly 6 includes a T-shaped bracket 61, connecting columns 62, and rubber heads 63. Four corresponding T-shaped brackets 61 are fixed between the four tower legs 1. Two corresponding T-shaped brackets 63 are fixed on the side of the T-shaped brackets 61. The connecting column 62 has rubber heads 63 fixed on its end face. All rubber heads 63 are respectively attached to the sides of the four connecting strips 41. The connecting assembly 7 includes a connecting block 71, a connecting plate 72, and a connecting groove 73. A connecting block 71 is fixed on the upper side of the connecting strip 41, and a connecting plate 72 is fixed between the four connecting blocks 71. A connecting groove 73 is opened at the upper end of the connecting plate 72. The connecting assembly 7 serves as the interface between the tower and the upper wind turbine equipment. Quick alignment and installation are achieved through the connecting plate 72 and the connecting groove 73. The connecting block 71 distributes the upper load to the connecting strip 41, reducing stress concentration and ensuring a stable connection of the tower top during unit operation. The third buffer assembly 6 is used to suppress the relative displacement and vibration transmission between the tower legs 1. T-type support The frame 61 provides lateral support, and the rubber head 63 fits into the connecting strip 41. The elastic deformation of the rubber absorbs high-frequency vibration energy, prevents resonance between the legs, and enhances the stability of the device under extreme weather conditions. The arc plate 53 slides in the T-shaped groove 51 through the sliding frame 52. Combined with the elastic deformation of the second spring 55, the arc plate 53 is allowed to move slightly under wind load, thereby consuming the swaying energy of the tower. The rotating connection of the connecting column 54 avoids rigid constraints, realizes flexible buffering, and reduces the risk of local fatigue of the tower. Modular assembly is realized through the connecting strip 41 and the connecting flange 42, which facilitates transportation and on-site installation. The connecting flange 43 provides a high-strength rigid connection to ensure the integrity of the tower under wind load, and at the same time provides an installation foundation for the upper second buffer component 5.

A first spring 36 is fixed to the end face of the damping disc 35 and the other end of the first spring 36 is fixed inside the fixed barrel 33. Two corresponding connecting frames 37 are fixed to the side of the reinforcing frame 2. The end of the sliding rod 34 away from the damping disc 35 is hinged to the inside of the corresponding connecting frame 37. Stable support is provided by four tower legs 1. The first buffer assembly 3 uses the sliding friction of the spring and the damping disc 35 to absorb the initial energy from foundation vibration and wind load, reducing stress concentration at the tower root.

[0023] The connecting plate 72 has a connecting ring 8 fixed on its circumferential surface. The upper end of the connecting ring 8 has evenly distributed connecting holes 14. The connecting ring 8 and the connecting holes 14 provide additional mounting points for fixing cables or auxiliary equipment, preventing cable tangling and wind-induced wear. The evenly distributed connecting holes 14 facilitate adjustment of the installation position, improving the practicality and maintainability of the device.

[0024] Among them: the support plate 31 has a threaded groove on the lower side, and the threaded groove is connected to a threaded post 9. The lower end of the threaded post 9 is fixed with a tapered fixing post 10. The threaded post 9 and the tapered fixing post 10 allow the device to be deeply anchored to the foundation. The tapered design enhances the pull-out resistance and prevents the foundation from slipping. It is suitable for soft soil or mountainous environments.

[0025] The support plate 31 has four corresponding fixing holes on its upper side. A reinforcing ring 11 is fixed inside the fixing hole. The reinforcing ring 11 is embedded in the fixing hole to increase the local stiffness and compressive strength of the support plate 31, prevent deformation under long-term load, and extend the service life of the first buffer component 3.

[0026] Among them: the four tower legs 1 are fixed with evenly distributed reinforcing ribs 12, and the four tower legs 1 are fixed with reinforcing frames 13. The reinforcing ribs 12 and the reinforcing frames 13 form a mesh support structure, which improves the bending and torsional resistance of the tower legs 1, reduces lateral deformation caused by wind load, and ensures the structural integrity of the device under strong wind.

[0027] Wherein: a locking post 15 is fixed on the lower side of the connecting strip 41, and a locking groove is opened on the upper side of the tower leg 1. The locking post 15 is locked into the corresponding locking groove. The locking design of the locking post 15 and the locking groove enables quick positioning and pre-installation, avoids the connecting strip 41 from shifting during hoisting, improves assembly efficiency, and provides additional shear resistance, enhancing the connection reliability between the support component 4 and the leg.

[0028] The working principle of the segmented vibration-resistant reinforcement support device for wind turbine towers provided by this invention is as follows: The foundation support system, consisting of four tower legs 1 and their side reinforcement frames 2, provides a stable load-bearing foundation for the entire device. When dynamic loads such as wind loads, turbine operation vibrations, or earthquakes act on the tower, the first buffer component 3 initiates a response: the vibration energy is transmitted to the inclined block 32 through the support plate 31, driving the hinged fixed barrel 33 to produce an adaptive deflection, pushing the slide bar 34 to move, causing the damping disc 35 to slide within the fixed barrel 33 to generate frictional damping. At the same time, the first spring 36 undergoes compression or tension deformation, converting the foundation impact kinetic energy into heat energy dissipation, effectively reducing the vibration amplitude and stress concentration at the tower root. When the remaining vibration energy is transmitted upward to the middle of the tower, the support component 4, through the connecting strip 41 and the connecting flange, 42. Distribute the load, and at the same time, the second buffer component 5 starts to work: the arc plate 53 transmits the force to the sliding frame 52 through the connecting column 54, so that it slides in the T-shaped sliding groove 51 and compresses the second spring 55, and consumes the swing energy in the middle of the tower through friction and elastic deformation; the third buffer component 6 simultaneously suppresses the vibration between the legs: the T-shaped bracket 61 fits against the side of the connecting strip 41 through the rubber head 63 at the front end of the connecting column 62, and uses the elastic deformation of the rubber to absorb high-frequency vibration and prevent the legs from resonating; the connecting component 7 achieves a stable connection with the upper equipment through the connecting block 71, the connecting plate 72 and the connecting groove 73; the auxiliary structure includes the threaded column 9 and the tapered fixed column 10 to enhance the foundation anchorage, the reinforcing ring 11 to increase the stiffness of the support plate 31, the reinforcing rib 12 and the reinforcing frame 13 to form a mesh reinforcement system, and the clamping column 15 cooperates with the clamping groove to simplify the installation process.
