Modular Systems for Wind Turbine Assembly

Modular wind turbine system that allows scaling wind power generation capacity by connecting multiple smaller turbines into a larger structure. The modular turbine has a stator with a housing containing a generator, and a turbine with multiple rotors separated by plates. Each rotor has magnets. The turbine sections can be connected to form a larger turbine with more rotors and power output. An anemoscope and motors on the stator baffles can adjust rotation and deflection angles for optimal power capture based on wind direction and speed. This allows scaling wind power capacity by connecting multiple smaller turbines into a larger structure.

Planetary blade wind turbine with multiple power units that maximize wind energy capture in a compact space. The turbine has a fixed shaft and multiple rotating shafts with blades. The blades are connected to the fixed shaft via worm gears. The blades have swinging wings to buffer wind loads. The rotating shafts are stacked like planetary gears around the fixed shaft. This allows all blades to rotate together when wind hits one side. It prevents the blades on the other side from spinning. The turbine has multiple power units arranged like planetary gears around the fixed shaft. The blades on adjacent units rotate in opposite directions. This allows simultaneous blade rotation on both sides of the fixed shaft.

A method and mobile factory for modular wind turbine blade assembly. This method involves manufacturing blade sections at a factory, transporting them to the wind turbine site, and using a movable factory platform to connect the sections in the field. This approach enables the production and transport of longer blades in shorter, more manageable sections that can be joined on-site.

Electric generators designed for wind turbines that are compact yet scalable to very high power outputs. The generator utilizes multiple axial flow electrical machines with coaxial rotors and surrounding stators. The rotors can be manufactured independently and then secured together to generate multiple magnetic fluxes simultaneously when rotated. This modular design allows for the combination of multiple machines of the same or different sizes and technologies to increase power output.

A modular wind turbine blade design and manufacturing method that simplifies the assembly of turbine blades on-site. The modular blade design utilizes double-tapered connections between blade sections. A connecting member with double-tapered ends links two blade modules together. Each module incorporates an internal double-tapered channel. These matching double-tapered connections enable modules to be aligned and easily joined during assembly. The double tapers provide self-aligning assembly and create strong connections between the modules. Additionally, a blade module manufacturing process using tapered molds is described.

A modular wind turbine blade design enabling longer blades to be divided into shorter modules for easier transportation and on-site assembly. The blade modules feature a tapered dovetail joint and a connecting member that securely fits into the joint to connect the modules. During manufacturing, the blade modules are produced using a split mold assembly with a tapered feature to create the dovetail joint recess in the blade shell. This process ensures precise alignment and bonding of the connecting member to the spar inside the recess. The double-tapered dovetail joint provides a robust, self-aligning connection between the blade modules.

Multi-segment rotor blade for horizontal-axis wind turbines that allows pitch angle control of each blade segment to optimize performance and reduce loads. The blade is made up of multiple segments that can rotate relative to each other to change the pitch angle. The blade segments are connected by guiding structures and actuating mechanisms that allow variable pitch between segments. This enables independent pitch control of each segment for optimal angle of attack and feathering. The blade design increases efficiency, reduces loads, and allows transportation of larger blades.

Concrete wind turbine towers that are assembled from cylindrical segments joined at vertical flanges. The invention enables more accurate and efficient assembly of wind turbine towers. It provides alignment tools and systems that mount on the tower segments' vertical flanges to guide their connection. These tools have heads with surfaces that engage and slide along opposing flanges during assembly, aligning them. This ensures the bolt holes in the flanges line up properly. The tools avoid direct contact with the flanges to prevent damage during alignment.

Modular brushless permanent magnet motor/generator design for large direct drive turbines. The design uses segmented rotor and stator rings that can be manufactured in sections and assembled on-site. This enables large diameter, high power generators without the need for a gearbox. The rotor segments contain magnet modules that encircle the stator segments containing coil modules. The modular design allows the stator and rotor to be manufactured in sections that are assembled on-site, reducing transportation and installation challenges. The rotor and stator segment also allows for automatic calibration to maintain optimal air gap distance.

Modular transportation and storage system for wind turbine blades that can be flexibly adjusted to accommodate different sizes and shapes of blades. The system includes modular tip end and root end frames that can be configured to hold blades at different angles. This allows blades with varying dimensions to be securely stored and transported together, reducing damage and costs. For example, the tip end frame can support blades vertically or at an angle, while the root end frame can rotate to match blade orientations.

A wind turbine design with multiple concentric rings of blades attached around the hub to improve efficiency and enable portability. The rings hold the blades in place and provide support to the hub. The rings can be detached for transport and reassembled at the installation site. This allows the turbine to be easily moved and set up in multiple locations. The multiple rings of blades around the hub also improves efficiency compared to a single blade design. The rings can be spaced apart to optimize blade angles for different wind speeds.

A wind power generation system that improves efficiency and reduces cost compared to conventional wind turbines. The system uses an upper wind power generation unit on top of a tall tower. The upper unit has an internal vertical axis wind turbine (VAWT) with blades that can rotate in both directions. This allows power generation from winds coming from any direction, unlike horizontal axis turbines that need winds from the side. The upper unit also has an outer vertical axis turbine that can stop rotation in high winds to prevent damage. The tower has an intake duct for the internal turbine and an outlet duct for the external turbine. This allows wind to be shared between the inner and outer turbines. The tower bottom has an inlet damper and air supply duct for the internal turbine. This allows wind to be shared between the tower-mounted turbines and the tower-top turbine. The tower also has an
