Description

Technical Field

[0002] Traditional wind turbine towers are mostly constructed of steel or concrete, which presents problems such as heavy weight, difficult transportation and installation, and high carbon emissions. Steel towers require flange connections in ultra-high sections, which can easily lead to stress concentration and fatigue damage. Concrete towers, on the other hand, suffer from long construction cycles and heavy weight. Existing research on wooden wind turbine towers is mostly limited to miniaturization applications, which cannot meet the load-bearing requirements of modern large-scale wind turbines. At the same time, traditional towers lack intelligent monitoring and adaptive adjustment capabilities, resulting in insufficient dynamic performance under complex wind load conditions. Protection mainly relies on periodic painting and maintenance, lacking self-healing functions, and their durability is limited in harsh environments. In addition, existing tower systems have limited functions and fail to effectively integrate additional functions such as renewable energy collection. These technical bottlenecks restrict the development of wind turbine towers towards lightweight, intelligent, and multifunctional designs, urgently requiring breakthroughs in innovative structural design and material systems.

Each segmented equal-section cylinder 1 is equipped with a bamboo-joint-like intelligent connection system 2. The multiple segmented equal-section cylinders 1 are coaxially assembled via the bamboo-joint-like intelligent connection system 2. The wall thickness of the multiple segmented equal-section cylinders 1 increases non-linearly from the top to the bottom, and the wall thickness gradient satisfies the relationship: δ(h)=δ_0+k·h^n, where δ_0 is the initial wall thickness at the top, k is the material coefficient, n is the gradient exponent, and h is the height from the top. The cross-section of each segmented equal-section cylinder 1 is a bamboo-like structure, with its circumscribed circle diameter gradually increasing from 3000mm at the top to 5000mm at the bottom. Each segmented equal-section cylinder 1 includes wood-plastic composite structural members 101, the number of which is... Eight wood-plastic composite structural members 101 are interlaced and wound at a golden spiral angle. Fiber-reinforced transition layers 102 are fixedly connected to the top and bottom of each wood-plastic composite structural member 101. End caps 105 are fixedly connected to the top and bottom of each fiber-reinforced transition layer 102. High-strength steel bars are embedded inside each wood-plastic composite structural member 101.

Gravity dampers 104 are fixedly connected to the bottom of the connectors 103. The gravity dampers 104 are located at the bottom of the upper end cap 105. The number of segmented equal-section cylinders 1 is 4 to 10, which can be flexibly changed according to construction needs. The wind turbine tower adopts a multi-segment design with a bamboo-like structure. The wall thickness increases non-linearly from the top to the bottom to optimize material distribution and improve structural efficiency. The segmented cylinders are coaxially assembled through an intelligent connection system to form an overall stress system. The wall thickness changes according to a specific gradient relationship to ensure smooth stress transmission and reduce the risk of local stress concentration. The wood-plastic composite structural materials are arranged in a biomimetic helical angle to enhance circumferential and axial mechanical properties. The fiber-reinforced transition layer is set at the end of the cylinder to effectively alleviate the abrupt change in stiffness between different materials and improve connection reliability. The end caps work together with the internal prestressed high-strength steel bars to further enhance the overall stiffness and fatigue resistance.

[0020] The fiber-reinforced transition layer 102 comprises the following alternating structures: a first transition layer with a thickness of 0.5 to 1.2 mm, which is a two-way mesh fabric woven from bamboo fiber and polylactic acid fiber in a 3:1 ratio; and a second transition layer with a thickness of 2 to 3 mm, which comprises a honeycomb balsa wood filler and a glass fiber reinforced epoxy resin layer covering it, with a honeycomb pore size of 5 to 8 mm and a wall thickness of 0.2 to 0.5 mm. The fiber-reinforced transition layer adopts a multi-layer composite structure, combining high-strength fiber braid and lightweight honeycomb filling material to achieve a balance between stiffness and toughness. The interface between the transition layer and the wood-based plywood is treated with a special process to enhance the interlayer bonding force. The connection between the end cap and the transition layer adopts high-precision processing technology to ensure the continuity of the load transfer path. This design significantly reduces stress concentration and improves the fatigue life of the overall structure.

The intelligent connection system adopts a bamboo-like design, combined with a shape memory alloy pre-tightening ring and a six-claw bionic connector, to achieve high-precision assembly and dynamic load adaptation. The connector optimizes the contact stress distribution through curved meshing teeth to reduce local wear.

The preload force F_p of the six-claw bionic connector is determined by the following formula: F_p = (0.6-0.8)·(E·A·α·ΔT), where E is the elastic modulus of the connector, A is the contact area, α is the coefficient of thermal expansion, and ΔT is the working temperature difference.

[0023] The outer surface of the segmented, uniform cross-section cylinder 1 is equipped with a self-healing protective system, including: a bottom layer: a polyurethane matrix with a thickness of 0.5-1mm containing microcapsule repair agent with a capsule diameter of 50-100μm and a core material that is a mixture of two-component epoxy resin and curing agent; a middle layer: a hydrophobic modified cement mortar with a thickness of 2-3mm, a surface contact angle θ≥150°, and a roll-off angle ≤5°; and an outer layer: a graphene conductive film with a thickness of 0.2-0.5mm, a resistance ≤5Ω / sq, and an adhesion grade ≥3B. The outer surface of the tower is equipped with a multi-layer self-healing protection system, including a microcapsule repair layer, a hydrophobic intermediate layer, and a conductive outer layer. The microcapsule repair agent is released when the crack expands, enabling the material to repair itself. The hydrophobic layer effectively blocks the penetration of moisture and corrosive media. The conductive outer layer has both anti-icing and monitoring functions, improving the durability of the structure in harsh environments. The protection system has been verified by accelerated aging in the laboratory, showing excellent long-term performance stability.

The core material includes: component A: 60-70wt% bisphenol A type epoxy resin; component B: 30-40wt% modified amine curing agent; wherein component A and component B are precisely encapsulated in a 1:1 volume ratio using microfluidic technology.

[0025] The manufacturing process of the segmented constant cross-section cylinder 1 includes the following steps: S1, Parametric modeling: Based on ANSYS topology optimization, determine the wall thickness gradient distribution and generate the laying path of each layer of single board; S2, Robotic Layup: Automatic layup is performed using a six-axis robotic arm with a positioning accuracy of ≤±0.1mm and a layup speed of 10~15m / min; S3, microwave curing: frequency 2.45GHz±50MHz, power density 3~5W / cm², temperature gradient controlled in three stages from 120℃ to 80℃ to 150℃; S4, Laser finishing: End face processing is performed using a 3kW fiber laser, with a cutting speed of 20-30mm / s and a focal diameter of ≤0.1mm; The tower manufacturing process employs parametric modeling and robotic automated layup technology to ensure geometric accuracy and material consistency. Microwave curing optimizes resin distribution and curing effect, reducing internal defects. Laser finishing technology ensures end face processing accuracy, meeting the assembly requirements of the intelligent connection system. A vision positioning system corrects layup deviations in real time, improving manufacturing efficiency and quality control.

[0026] In step S2, a visual positioning system is used to compensate for the layup error in real time, including a high-resolution CCD camera: resolution 2448×2048 pixels, sampling rate 1000fps; a laser displacement sensor: measurement range ±5mm, accuracy 0.01mm; and an online compensation algorithm: real-time path correction based on the least squares method, with an iteration period ≤10ms. The tuned mass damping system is designed based on the structure's natural frequency. It dissipates vibration energy through the synergistic effect of the mass block and elastic elements. The active control algorithm dynamically adjusts the damping parameters based on real-time monitoring data, effectively suppressing wind-induced vibration. This system significantly reduces the dynamic response of the tower, improving operational safety and comfort.

[0027] The segmented, uniform cross-section cylinder 1 is internally equipped with a tuned mass damping system, comprising: a mass block made of tungsten alloy, with a mass M = (0.3-0.5)% of the total mass of the tower; a spring assembly consisting of parallel disc springs and rubber dampers, with a stiffness ratio K_s / K_r = 2:1; and a control system based on the LQR algorithm, with a sampling frequency ≥ 1 kHz and a phase lag ≤ 5°. The operating frequency f_d of the tuned mass damping system satisfies: f_d=(0.95-1.05)·f_n, where f_n is the first natural frequency of the tower, calculated by the following formula: f_n=(1 / 2π)·√(3EI / (mH^4)), where E is the equivalent elastic modulus, I is the moment of inertia of the section, m is the mass per unit length, and H is the total height of the tower; The segmented, uniform cross-section cylindrical integrated photovoltaic power generation system includes: a flexible photovoltaic film with a conversion efficiency ≥22% and a bending radius ≤50mm; an energy storage module: a graphene supercapacitor array with an energy density ≥50Wh / kg; and an intelligent power distribution system with maximum power point tracking and an efficiency ≥98%. The tower's outer surface integrates a flexible photovoltaic film, incorporating renewable energy sources other than wind power into the power supply system. A supercapacitor energy storage module provides rapid charging and discharging capabilities to balance power fluctuations. An intelligent power distribution system optimizes energy allocation and improves self-sufficiency. This design expands the tower's functionality and reduces operation and maintenance energy consumption. Accelerated fatigue testing and long-term environmental exposure testing verify the tower structure's performance stability throughout its entire lifecycle. An intelligent monitoring system tracks key mechanical parameters in real time, providing a basis for maintenance decisions. Biomimetic connections and self-healing designs significantly extend the structure's lifespan and reduce overall lifecycle costs. This tower system demonstrates significant advantages in sustainability and economy.

[0028] This hollow, segmented, bamboo-like wooden wind turbine tower structure achieves a significant breakthrough in lightweighting through biomimetic design and intelligent material systems. Its core innovation lies in combining the structural principles of natural bamboo with modern composite material technology to construct a novel tower system that combines lightweight, high strength, and dynamic adaptability. The segmented cylinder uses biomimetic spiral-wound wood-based adhesive as its main structure. An optimized fiber-reinforced transition layer achieves a gradient change in material properties, significantly reducing its weight while maintaining structural integrity. The wall thickness design follows a non-linear increasing law, meeting the load-bearing requirements at the bottom while avoiding material redundancy at the top, achieving optimal weight distribution balance. The intelligent connection system is another key to the structure's lightweighting; its bamboo-like segment design not only simplifies the connection construction but also... The use of shape memory alloys and optimized meshing tooth profiles achieves a balance between weight reduction and efficient force transmission. The miniaturization of the distributed monitoring module further reduces the added mass. The outer protection system adopts a multi-layer composite design, integrating self-healing function and superhydrophobic properties into a lightweight film, which significantly reduces maintenance weight compared to traditional protective coatings. The built-in tuned mass damping system achieves excellent vibration control with minimal mass through material selection and parameter optimization. The structure also innovatively integrates renewable energy components. The integrated design of the flexible photovoltaic system and energy storage module avoids the additional weight of external equipment. Overall, through collaborative innovation in three dimensions—material selection, structural topology optimization, and functional system integration—this tower has achieved a qualitative leap in lightweighting while ensuring structural safety.
