Description

Technical Field

[0001] This invention belongs to the field of special structure composite material preparation technology, specifically relating to a cross-regional self-assembly equipment for wind turbine blades and its braided connection method. Background Technology

[0002] Wind energy is a clean and renewable energy source, using wind power to drive wind turbines and convert kinetic energy into electrical energy. With increasing global emphasis on environmental protection and energy structure adjustment, wind energy is being increasingly widely used in the renewable energy sector. Wind power generation not only reduces dependence on fossil fuels and lowers greenhouse gas emissions, but also boasts the advantages of abundant and widely distributed resources. Continuous advancements in modern wind power technology have improved power generation efficiency and system stability, making wind energy a crucial support for achieving a low-carbon economy and sustainable development. The development of wind energy is of great significance for promoting energy structure transformation and achieving sustainable development goals.

[0003] With the continuous advancement of wind power technology, wind turbine blades are trending towards larger sizes. Data shows that the average rotor diameter for onshore wind turbines has increased from 135 meters in 2020 to 195 meters in 2024; during the same period, the average rotor diameter for offshore wind turbines increased from 152 meters to 235 meters. The increased blade size allows them to capture wind energy over a wider area, significantly improving single-unit power generation efficiency and overall performance to meet the ever-growing demand for electricity.

[0004] Over the past decade, blade lengths have gradually increased from tens of meters to over a hundred meters, bringing greater energy conversion capabilities and economic benefits. However, the increase in blade size has also brought numerous challenges. Ultra-long blades face problems such as space constraints, difficulties in road access, and increased safety risks during manufacturing, transportation, and installation. Transportation requires specialized vehicles and route planning, significantly increasing logistics and time costs, while also placing higher demands on infrastructure. These issues have become key bottlenecks that the wind power industry must address in developing ultra-large blades, affecting the speed of wind power project implementation and economic benefits.

[0005] To effectively address the challenges of transporting and installing large wind turbine blades, segmented wind turbine blade technology has gradually emerged and gained widespread attention. This technology, by designing the blade as multiple detachable parts, facilitates segmented transportation, not only solving the bottleneck of transporting ultra-long blades but also improving the flexibility and adaptability of wind power projects, enabling the application of larger blades. However, traditional segmented blade connection methods suffer from problems such as bulky connection structures, low assembly precision, and stress concentration at the connection points, which can easily lead to decreased structural fatigue performance and limit the development of blades towards longer dimensions and higher performance. For example, the rigid connection fastening method using clips, slots, and bolts is employed in Chinese utility model patent CN222254203U (A Segmented Wind Turbine Blade). While this type of method offers advantages in structural reliability and disassembly, it typically involves additional metal connector mass, potentially causing uneven stress distribution at the joints and hindering structural lightweighting. Patent CN118934503A (A Segmented Wind Turbine Blade and Splicing Method) utilizes an inner skin butt joint, layer-by-layer reinforcement fabric laying, and final resin injection molding to achieve segment-to-segment connection. This method effectively avoids metal connectors and optimizes the load transfer path through large-area adhesive bonding. However, its process involves multiple manual on-site operations, heavily relying on operator skills and experience, and exhibiting high complexity in process control. Therefore, developing a connection device and method capable of achieving biomimetic structural weaving to optimize stress distribution at the joints and achieve lightweight and high-performance connections is of great significance for improving the overall performance of carbon fiber reinforced aluminum alloy wind turbine blade structural components. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The present invention aims to provide a cross-regional self-assembly equipment for wind turbine blades and its braided connection method, in order to solve the problems of equipment separation, complicated procedures, low positioning accuracy, and difficulty in directly preparing high-performance composite material connection layers with specific biomimetic arrangement structures in the field assembly of large segmented blades in the existing technology.

[0008] To address this, a biomimetic design and functional integration approach is adopted. Based on the high-efficiency load-bearing principle of biological structures, specialized equipment is used to achieve the spacing and weaving of fiber bundles, resulting in a composite material reinforcement layer with higher load-bearing efficiency. By adjusting the fiber bundle spacing and weaving angle, the stress distribution and lightweight level of the connection structure are optimized. Compared with traditional mechanical connections or simple weaving methods, this technology integrates mobile transfer, positioning adjustment, on-site welding, and automated biomimetic weaving functions into a single piece of equipment, realizing a continuous "transfer-positioning-welding-weaving" integrated operation solution without significantly increasing process complexity, meeting the high-performance and high-efficiency on-site connection requirements of large wind turbine blades.

[0009] Technical solution

[0010] A cross-site self-assembly equipment for wind turbine blades is characterized by comprising a mobile support unit, a positioning and adjustment module, a biomimetic weaving component, and an intelligent control terminal. The mobile support unit is located at the bottom of the equipment and is used to provide stable cross-site transportation. The positioning and adjustment module is mounted on the mobile support unit and is used to clamp the segmented shells of the wind turbine blades and adjust their spatial attitude and position. The biomimetic weaving component is mounted on the mobile support unit and is used to weave carbon fiber bundles in the blade connection area. The intelligent control terminal is communicatively connected to the mobile support unit, the positioning and adjustment module, and the biomimetic weaving component to control the coordinated operation of each component.

[0011] The biomimetic woven assembly is the core component connecting segmented wind turbine blades. Its internal functional mechanisms include fiber guiding and tension control units. After being drawn out from the pre-embedded liner, the carbon fiber bundles are spatially arranged via guides and maintained at a constant preset tension under the precise control of the tension controller. By controlling the movement of the woven kit along the slide rail in coordination with the blade rotation, multiple independent carbon fiber bundles are directly woven into a continuous, reinforced preform with a predetermined biomimetic structure on the surface of the connection area.

[0012] This invention provides a fiber weaving method for carbon fiber reinforced wind turbine blade structural components, employing the aforementioned cross-regional self-assembly equipment, which includes the following steps:

[0013] S1. Positioning Welding: The segmented blades are transported to the designated assembly position and precisely positioned and calibrated using the positioning adjustment module. The aluminum alloy liner plates at the ends of the segments are then joined together. The blade shells are clamped by chucks and connected to the pre-embedded alternating "convex and concave" shaped aluminum alloy liner plates by welding, thus completing the rigid connection and positioning.

[0014] S2. Bionic Weaving: Using the welded aluminum alloy liner as the anchoring base, the bionic weaving assembly is activated. Carbon fiber bundles, drawn from the welded aluminum alloy liner by a carbon fiber traction device, are spatially positioned and tensioned under the coordination of a guiding and tension control mechanism. By controlling the movement speed, weaving angle, and fiber bundle spacing of the bionic weaving kit along the slide rail, multiple independent carbon fiber bundles are directly woven into a continuous reinforcement layer with a predetermined bionic structure on the surface of the connection area. During the weaving process, the fiber bundles are laid out in a cross-layout at ±45° to the blade axis. The weaving pattern, tension, and gap are precisely controlled by an intelligent control terminal. Based on the different performance design requirements of the segmented blades in various parts of the connection structure, a bionic arrangement structure for the carbon fiber reinforcement layer is selected. This arrangement structure includes both tight, seamless cross-layouts and cross-layouts with gaps. For a tight, seamless cross-layout, all carbon fiber bundles are cross-woven under constant high tension, with adjacent bundles tightly bonded together to form a dense, mesh-like load-bearing structure. For a cross-layout with gaps, the fiber bundle guide spacing is adjusted to ensure that adjacent carbon fiber bundles maintain a predetermined uniform gap after weaving, while maintaining a cross-layout angle of ±45°, forming a biomimetic hollow structure with regular mesh-like gaps. Resin will fill these gaps in subsequent processes.

[0015] S3. Resin Curing: After weaving is completed, an epoxy resin system is prepared. This epoxy resin system is composed of E51 type epoxy resin and a curing agent mixed at a mass ratio of 2:1. The mixed resin system is placed in a defoaming tank for degassing treatment. The defoamed resin is then evenly applied and impregnated onto the surface and gaps of the woven carbon fiber bundles in the blade connection area. The resin serves to protect the carbon fibers, fill the gaps between the fiber bundles, and bond and cure, ultimately forming a high-performance carbon fiber composite reinforcement layer in the connection area.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this invention are:

[0018] This invention effectively solves the bottleneck problems in traditional large-scale segmented wind turbine blade connections, such as poor overall structural reliability, high manufacturing costs, and difficult maintenance due to low on-site assembly precision, bulky connection structures, insufficient fatigue strength, and low efficiency of manual or semi-automatic processes. By innovatively adopting a composite connection process of "positioning welding-fiber weaving" and using dedicated cross-site self-assembly equipment, lightweight, high-strength, and high-precision assembly of the connection structure is achieved. This method does not significantly increase process complexity, but significantly improves the static load strength, fatigue resistance, and long-term reliability of the connection parts, fully leveraging the advantages of both carbon fiber composite materials and metal materials. The equipment features high integration and automation, is adaptable to field operation environments, and has a smooth operating process. The resulting blade connection structure can meet the high-performance, high-efficiency manufacturing and rapid on-site assembly requirements of future ultra-long, large-scale wind turbine blades, and has broad application prospects in both onshore and offshore wind power fields.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] This example focuses on carbon fiber reinforced wind turbine blade structural components, specifically demonstrating how to manufacture blade segments pre-embedded with aluminum alloy liners and carbon fiber bundles in a factory environment. This provides qualified wind turbine blade structural components for subsequent inter-regional transport and on-site connection. The details are as follows:

[0032] Mold preparation:

[0033] Pre-fabrication is carried out in a specialized composite blade negative mold. The mold adopts a composite material profile structure supported by a steel frame. Its profile is made of high-strength epoxy resin and carbon fiber composite material laminated together, and is precision CNC machined and repeatedly polished to form a smooth cavity that perfectly matches the aerodynamic shape of the blade design. This profile has high precision, high rigidity, low coefficient of thermal expansion, and excellent demolding performance. The supporting frame is a three-dimensional spatial frame welded from heavy-duty steel, firmly connected to the factory foundation, providing rigid support for the tens of meters long mold to withstand process loads and ensuring minimal mold deformation during molding.

[0034] Before the layup process begins, the mold surface is thoroughly cleaned. Then, a high-gloss semi-permanent polymer release agent is sprayed evenly, typically in three coats, with each coat spaced at specific intervals and allowed to fully cure, to form a complete, dense, and smooth release film, ensuring the surface quality of the final product and facilitating demolding.

[0035] Structural layup:

[0036] The layup proceeds from the blade root towards the blade tip. First, the inner skin layer of the blade shell is laid, using ±45° biaxial carbon fiber fabric. Workers precisely lay the fabric according to laser-projected positioning lines, repeatedly compacting it with rollers to remove air. When the layup reaches approximately 2.5 meters from the segment end face, it is paused, and the installation of key connectors begins. Using a bridge crane and specialized lifting equipment, the aluminum alloy liner is smoothly lifted into the pre-set cavity position within the mold. This liner is 2.2 meters long, and its outline matches the position of the blade's main beam cap and web. The liner is then finalized using a high-precision three-dimensional fine-tuning positioning fixture integrated into the mold. After confirming correct positioning, the liner is temporarily bolted to the steel frame of the mold.

[0037] Pre-embedded carbon fiber bundles:

[0038] The main load-bearing structural layer continues to be laid around the fixed aluminum alloy liner. At the main beam cap location, T700 unidirectional fabric is laid axially while carbon fiber bundles are pre-embedded. Simultaneously, 24 guide holes with a diameter of 6 mm are pre-machined inside the aluminum alloy liner, with the hole axis at ±45° to the blade axis. Before pre-embedding, an appropriate amount of resin is injected into each guide hole. Individual carbon fiber bundles are drawn from the 24 independent carbon fiber bundle axes. Each fiber bundle first passes through the corresponding pre-insulated guide hole in the liner to form an anchor point. Then, workers hold the fiber bundles and lay them straight between the stacked carbon fiber fabric layers along a ±45° path pre-marked on the uncured layup. The fiber bundles extend from the liner, leaving a 1.5-meter tail end, and pass through a temporarily installed flexible conduit, leading out of the current layup and the future vacuum bag system, and are fixed to a special bracket at the edge of the mold with numbered clips. Above the path area where the carbon fiber bundles are embedded, subsequent structural layers are laid to ensure that these embedded bundles are completely enclosed and integrated with the surrounding composite material.

[0039] Curing and molding:

[0040] After all structural layers are laid up, encapsulation is performed according to standard vacuum infusion process: release fabric, flow guide net, vacuum bag film are laid up sequentially and sealed. Special attention is paid to the area where the tail ends of the 24 carbon fiber bundles pass through the vacuum bag, requiring special sealing treatment to ensure vacuum level. The mixed and degassed epoxy resin is introduced into the system under vacuum negative pressure. The resin fully impregnates all dry fibers, embedded carbon fiber bundles, and fills the interface between the liner and the composite material. After infusion, the entire mold is transferred to a curing oven. The set curing program is executed: pre-curing at 40°C for 10 hours, then heating to 80°C at a rate of 0.8°C / min and holding at that temperature for 10 hours. During this process, the resin cross-links, and the carbon fiber fabric, embedded carbon fiber bundles, and aluminum alloy liner are co-cured and molded into a complete component in one step.

[0041] Demolding process:

[0042] After curing, the material is cooled to below 40°C before demolding. A large gantry milling machine is used to machine the end faces of the demolded segmented blades. First, using the blade main beam as a reference, a CNC milling cutter flattens the end face of the composite material. Then, the exposed aluminum alloy liner "boss" is precisely contour-milled to ensure that its contour dimensions and surface finish fully conform to the design drawings, guaranteeing a zero-gap connection with another "groove" liner on site. The temporary protection for the tail end of the carbon fiber bundle is carefully removed, combed, cleaned, and a protective cover is installed. A label indicating the number and specifications is then attached.

[0043] Example 2

[0044] This case study focuses on carbon fiber reinforced wind turbine blade structural components. The components are fabricated using a biomimetic weaving technique with carbon fiber, followed by vacuum resin infusion, curing, and finally performance testing to investigate the impact of different weaving structures on the performance of the wind turbine blade structural components. The specific details are as follows:

[0045] Position welding:

[0046] Using segmented blades made of T700 carbon fiber reinforced composite material, high-performance aluminum alloy liners are pre-embedded at the connecting ends during manufacturing. The mating surfaces of these liners are machined into matching concave-convex geometries to achieve self-positioning and effective load transfer during connection. During the docking process, a cross-regional self-assembly equipment first smoothly transports the two blade segments to a dedicated docking station. Then, through the integrated positioning adjustment module and hydraulic lifting system, the blades are precisely adjusted in six degrees of freedom, gradually bringing the concave-convex interfaces of the two liners closer together until precise alignment is achieved, maintaining a uniform gap of no more than 0.5 mm. Based on this, a non-consumable inert gas (NOG) shielded welding process is used to continuously weld the mated aluminum alloy liners. By strictly controlling heat input and weld formation, a complete, dense, and high-strength rigid connection foundation is established between the ends of the composite blades, thereby ensuring the continuity and reliability of the overall structure under subsequent stress.

[0047] Fiber weaving:

[0048] Using the welded aluminum alloy liner as the anchoring base, the biomimetic weaving kit is activated. Carbon fiber bundles, drawn from the welded aluminum alloy liner via a carbon fiber bundle traction device, are spatially positioned and tensioned under the coordination of a guiding and tension control mechanism. By controlling the movement speed, weaving angle, and fiber bundle spacing of the biomimetic weaving kit along the slide rail, multiple independent carbon fiber bundles are directly woven into a continuous reinforcement layer with a predetermined biomimetic structure on the surface of the connection area. During the weaving process, the fiber bundles are laid out in a cross-layout at ±45° to the blade axis, and the weaving pattern, tension, and gap are precisely controlled by an intelligent control terminal. Based on the different performance design requirements of the segmented blades in various parts of the connection structure, a biomimetic arrangement structure for the carbon fiber reinforcement layer is selected. This arrangement structure includes both a tight, seamless cross-layout and a cross-layout with gaps. For a tight, seamless cross-layout: all carbon fiber bundles are cross-woven under constant high tension, with adjacent bundles tightly bonded together to form a dense, mesh-like load-bearing structure; for a cross-layout with gaps: the spacing is controlled by guides to ensure that adjacent fiber bundles form a uniform gap of 3 mm width after weaving while maintaining a cross-angle of ±45°, creating a biomimetic hollow structure with regular mesh-like gaps. Resin will fill these gaps in subsequent processes.

[0049] Resin Curing: After weaving, an epoxy resin system is prepared. This system consists of E51 type epoxy resin and a curing agent mixed at a mass ratio of 2:1. The mixed resin system is placed in a defoaming tank for degassing treatment. The defoamed resin is then evenly applied and impregnated onto the surface and gaps of the woven carbon fiber bundles in the blade connection area. The resin protects the carbon fibers, fills the gaps between the fiber bundles, and acts as a bonding and curing agent, ultimately forming a high-performance carbon fiber composite reinforcement layer in the connection area.

[0050] Performance analysis of carbon fiber reinforced aluminum alloy composites prepared under the above preparation conditions:

[0051] The carbon fiber resin laminate formed on the wind turbine blade was cut and made into standard samples for tensile testing, three-point bending testing and impact testing.

[0052] Three carbon fiber laminates of each structure were prepared, and each underwent different performance tests. In the tensile test, the laminate strength, from strongest to weakest, was determined by cross-layout with a 3mm gap and tight, seamless cross-layout. The tensile strength of the tight, seamless cross-layout was 43.25 MPa, while the tensile strength of the cross-layout with a 3mm gap reached 66.39 MPa, representing a 53.5% increase compared to the traditional tight-layout structure. In the three-point bending test, the bending strength of the tight, seamless cross-layout structure was measured to be 40.01 MPa, while the bending strength of the cross-layout with a 3mm gap was 57.02 MPa, representing a 42.51% increase in bending strength. In the impact test, the impact energy absorption of the tight, seamless cross-layout structure was 2.245 J, while the impact energy absorption of the cross-layout with a gap was 2.856 J, demonstrating a significant 27.22% improvement in impact resistance. The above conclusions show that the gapped structure after biomimetic weaving has significantly improved tensile, bending and impact resistance properties compared with the traditional tightly laid structure, proving that the weaving method and equipment are effective and feasible, and have high reliability.
