Abstract
Description
Technical Field
[0001] Embodiments of the present invention generally relate to renewable energy power generation systems and equipment. In particular, this disclosure relates to wind turbine systems based on drag and lift, having adjustable blades. Background Technology
[0002] The topics discussed in the background section should not be considered prior art simply because they are mentioned there. Similarly, it should not be assumed that the problems mentioned in or related to the topics in the background section have previously been identified in the prior art. The topics in the background section represent only different methods, and they may themselves correspond to implementations of the claimed technology.
[0003] Renewable energy, often referred to as clean energy, has increasingly become one of the world's primary energy sources. With the depletion of non-renewable resources, increasing pollution, and ever-growing demand for electricity, the world is now turning its attention to renewable energy to meet energy needs without harming the environment. Two of the most popular renewable energy sources are solar and wind power. Wind turbines and windmills have existed for centuries and provide the cheapest energy in many parts of the world.
[0004] While the basic platform configuration of a three-bladed horizontal-axis upwind wind turbine on a single-pole tower hasn't changed much, the turbine size has increased by 6-7 times in hub height, 6-8 times in rotor diameter, and 30-50 times in rated power. Today, wind turbines can rival the size of large monuments and buildings, while enduring dynamic and complex loads throughout their lifespan. Most wind turbines consist of three blades mounted on a tower made of tubular steel. Less common varieties have two blades or concrete or steel lattice towers. At 100 feet or higher above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher elevations.
[0005] Turbines capture wind energy through their propeller-like blades, which function much like airplane wings, with only a small portion of the total area the blades sweep across in a circular motion coming into contact with the wind. When the wind blows, a low-pressure air pocket forms on one side of the blade. This low-pressure pocket then pulls the blade towards it, causing the rotor to rotate at a right angle to the wind direction—this is called lift. The lift is always less than the total force of the wind acting in front of the blade, attempting to push the blade in the direction of the wind; this is called drag, which is around 300% or more. A portion of the drag is converted into lift, causing the rotor to rotate like a propeller. A series of gears increases the rotor's rotation speed from about 18 revolutions per minute to about 1500 or 1800 revolutions per minute—a speed that allows the turbine's generator to produce alternating current based on the local power grid.
[0006] The streamlined outer casing houses key turbine components, typically including gears, rotors, and generators, all housed within a nacelle. Some nacelles are located atop the turbine tower and are large enough for a helicopter to land. Another established critical component is the turbine's controller, which adjusts the rotor speed to prevent damage from high winds exceeding 55 mph. An anemometer continuously measures wind speed and transmits the data to the turbine's controller. Brakes are also mounted in the nacelle to stop the rotor mechanically, electrically, or hydraulically in emergencies.
[0007] The angle between the direction of attack and the blade's pitch relative to the windward direction is called the "angle of attack." As this angle of attack increases, more lift is generated, but as the angle becomes larger, exceeding approximately 20 degrees, the blades begin to reduce lift. Therefore, there exists an ideal pitch angle for rotor blades to produce the optimal torque.
[0008] Clearly, this propeller-type wind turbine blade design converts only the lift energy of the wind into usable shaft power called torque. This is achieved by extracting energy from the wind by slowing or decelerating it as it passes over the blades.
[0009] Therefore, there is a need for a drag- and lift-based wind turbine system with adjustable blades that provide a larger blade contact area and can function even at low wind speeds and high wind speeds exceeding 200 km / h, improving efficiency, cost-effectiveness, and ease of maintenance.
[0010] Purpose of the invention
[0011] One object of the present invention is to provide a drag- and lift-based wind turbine system with adjustable blades, wherein drag and lift are combined to improve efficiency by rotating the blades with the wind rather than at right angles.
[0012] Another objective of the present invention is to use drag as the primary propellant and to increase lift by dynamically changing the angle of attack of the blades in response to their rotational position during each rotation.
[0013] Another object of the present invention is to provide a blade assembly comprising sub-blade panels that are rotatable on their own axes and can increase their operating wind speed range from less than 5 Mtrs per second to more than 80 Mtrs per second.
[0014] Another objective of this invention is to make wind turbines more cost-effective and easier to maintain. Summary of the Invention

In the following detailed description, numerical values and ranges are provided for various aspects of the described embodiments. These values and ranges are to be considered merely examples and are not intended to limit the scope of the claims.

Moreover, the terminology and wording used herein are for descriptive purposes only and should not be construed as limiting the scope.
[0035] The present invention provides a wind turbine system based on drag and lift, the wind turbine system having multiple adjustable blade panel assemblies and each blade panel assembly comprising multiple controllable (rotatable) sub-blades.
[0036] This invention, with its novel and inventive arrangement, enables the continuous and independent variation of the incident angle of each blade panel assembly during each rotation to optimize forward drag or reduce reverse drag and generate lift during component rotation. The arrangement is configured such that the wind is tangential to the rotation of the main rotor rather than blowing axially. One or more main rotors can be positioned vertically, horizontally, or at any angle in between, each rotor having one or more blade panel assemblies fixed to a corresponding arm and connected to the rotor at any position along its length. These auxiliary shafts of the blade panel assemblies are controlled by a main control unit and control devices (e.g., cam mechanisms, actuators, etc.) to adjust the incident angle of the blade panels relative to the wind direction, continuously varying within each rotation cycle. Output devices are provided to utilize the rotational energy from the turbine and main rotor.
[0037] Furthermore, because each blade panel assembly includes movable or controllable sub-blade panels, under normal wind / operating conditions, the sub-blade panels are in the closed position to block air (providing the maximum impact area for the wind) and generate maximum forward drag and lift. However, as the wind speed begins to exceed certain predetermined limits, the sub-blade panels of each blade panel assembly can be opened independently (partially or fully) to allow excess air to pass through the blade panels partially or completely. This independent control of the sub-blade panels helps maintain a constant forward torque, even when the wind speed changes by more than 30 times. This design feature eliminates the need for brakes to control rotation when wind speeds are too high. This method allows the collected rotational force to be transferred to be further converted into any other form of energy as needed.
[0038] The invention will now be described with reference to the accompanying drawings, which cover various embodiments of the invention.
[0039] Figure 1A An isometric view of a drag-based wind turbine system (100) in a vertical axis arrangement according to an embodiment of the present invention is illustrated. Figure 1A As shown, the drag-based wind turbine system (100) (hereinafter referred to as "system (100)") has been arranged in a vertical axis configuration. However, those skilled in the art will understand that the system (100) of the present invention can be arranged in any position on the vertical axis, horizontal axis, or in between without departing from the scope of the invention. Other types of arrangements have also been discussed in other embodiments of the invention, which will be explained in the following description. For better explanation and clarity, Figure 1A The front view and top view of the system (100) are also shown respectively. Figure 1B-1C middle.
[0040] like Figure 1AAs shown, the system (100) includes one or more output drive rotors (102) arranged on a base structure (120). The base structure (120) can be understood as a structure that allows the system (100) to reach a desired height and also houses the components of the system (100). The height may range from 1 meter to several hundred meters, depending on the type of application. Therefore, in this sense, the base (120) may be, but is not limited to, a tower, having one or more legs (1204) and one or more horizontal / vertical platforms (1202) to house the components of the system (100) (e.g., Figure 1A and 1B (As shown). Furthermore, if more than one wind turbine is used in a single system (100), there can be multiple base structures (120). One or more output drive rotors (102) can be arranged vertically or horizontally, or at any angle in series or parallel arrangement, depending on the arrangement type (horizontal, vertical, etc.) used in the system (100). One or more output drive rotors (102) serve as the hub of the entire rotating turbine and as a means of collecting energy generated by the system (100) and transferring it to other energy transfer devices, including but not limited to electrical, mechanical, hydraulic, thermal, etc.
[0041] To simplify the explanation, in Figure 1A-1C In the illustrated embodiment, only one output drive rotor (102) is shown vertically arranged on the base. Furthermore, one or more output drive rotors (102) are connected to one or more arms (104). The one or more arm structures can extend radially or tangentially from any end, both ends, or a portion between the ends of each of the one or more output drive rotors (102). For example, four arms (104) extend from... Figure 1A The top of the output drive rotor (102) shown extends radially (90 degrees apart). One or more arms (104) are connected to one or more output drive rotors (102) using a main control unit (106). The conceptual term "main control unit (106)" includes various types of mechanisms and combinations of various types of mechanisms / devices.
[0042] In this sense, one or more primary control devices (106) and secondary control devices (110) are selected from, but not limited to, cam and follower mechanisms, servo motors, belt and pulley mechanisms, chains and sprocket mechanisms, linear and rotary actuators (1066), gear mechanisms, lever mechanisms, centrifuges, hydraulic systems, pneumatic control, numerical control, stepper motors, electromagnetic motors, electromagnets, screw actuators, groove readers, digital and analog control, or combinations thereof. For example: Figure 1A-1BThe illustrated embodiment demonstrates the use of cams and followers in the form of a groove reader (1062) mechanism, a linear actuator, a control lever (1064), a rotary actuator (1066), a linear bearing, a gear mechanism, etc. The main control device is (106).
[0043] Figure 1A-1C The cam and follower (1062) mechanism used in the embodiments has been Figure 2A-2C It is shown in more detail below. Figure 2A-2C The arrangement of a cam and follower in the form of a groove reader, which serves as the main control unit (MCU) (112) of the present invention, is shown. Figure 2A In the diagram, the cam and follower (1062) mechanism is shown as being set in the MCU (112). Figure 2B and 2C The same open-top diagram and exploded diagram are shown respectively. From Figure 2A-2C As can be seen, the MCU (112) includes a housing (202). Furthermore, a cam (204) with a predetermined width and shape is disposed within the housing (202) and surrounded by four followers (206) connected to each control lever (1064). Linear actuators are attached to each of the four arms (104). Each follower (206) is fitted with two freely rotating wheels / bearings (208) appropriately sized to fit into a cam groove configured to move along the profile of the cam (204). The shape of the groove is pre-programmed to optimize the angle of attack for each blade panel assembly, assuming a predefined north wind direction during a full 360° rotation. When this full groove assembly rotates 90° clockwise, the optimal wind direction for all blades changes 90° from the existing north to east.
[0044] The rotation of the complete recessed assembly within the housing (202) is achieved via a gear assembly comprising a smaller drive gear (1070) that meshes with a direction control gear (1068), which, under the control of the main control unit (MCU) (112), is driven by a motor (not clearly visible) to ensure the wind turbine system (100) is in optimal condition in all wind directions. Based on input from a wind direction sensor, the drive gear (1070) assists in rotating the direction control gear (1068) with the housing (202) in the desired direction. Additionally, one or more auxiliary components (208), such as bearings, rivets, small wheels, rods, etc., may be provided to secure the components in place and achieve smooth relative movement.
[0045] It should be noted that the above or Figure 1A-1C and Figure 2A-2CAll components and linkages of the main control unit (106) shown are merely exemplary. These illustrate that the primary control unit (106) can be purely mechanical and can be pre-configured for automatic operation. However, the aforementioned components can be easily replaced by other electrical components listed in the above-described main control unit (106). The invention can simply use an electric motor instead of the cam follower (1062) or the linear and rotary actuators (1066). Furthermore, the connection between one or more output drive rotors (102) and one or more arms (104) (or any moving parts) can involve an electromagnet (e.g., in the housing (202)) and utilize magnetic levitation to optimize (eliminate in low wind speeds and increase in high wind speeds) friction between the moving parts. In this way, the number of required components (and moving parts) can be reduced.
[0046] Return to Figure 1A The system (100) also includes one or more blade panel assemblies (108) rotatably connected to one or more corresponding arms (104). Figure 1A-1C As shown, each arm (104) is connected to a blade assembly (108) at its distal end. As can be seen from Figure 1, each blade panel assembly (108) includes an auxiliary rotation shaft (1084) rotatably mounted on each of one or more arms (104) and connected via one or more main control devices (106). The main control devices (106) rotate the auxiliary rotation shaft (1084), thereby changing the angle of attack of each blade panel assembly (108). Furthermore, a mounting device (1082) is provided to connect to the auxiliary rotation shaft (1084). The mounting device may include one or more of a frame, connecting device, assembly device, etc.
[0047] In the example shown, the mounting arrangement is shown as including a blade frame that may have a square, rectangular, or any polygonal shape. Furthermore, each mounting device (1082) (in this example, a blade frame) has one or more sub-blade panels (1086) that are pivotable at one or more pivot points of the mounting device (1082). This is made possible by one or more auxiliary control devices (110) connected to the mounting device (1082). This allows one or more sub-blade panels (1086) to rotate (open and close), thereby blocking and / or allowing wind to pass partially or completely through the blade panels. In another embodiment, the mounting device (1082) may include directly rotatably securing / mounting the one or more pivotable sub-blade panels (1086) onto an auxiliary rotation shaft (1084) via a connecting device (without requiring any frame).
[0048] Figures 3A-3CThe illustration shows a blade panel assembly (108) having a sub-blade panel (1086) that is (a) closed, (b) partially open / closed, and (c) open. Figure 1A-1C Examples 3A-3C illustrate an embodiment in which the sub-blade panels (1086) are horizontally pivoted and divided into one per row. However, in other embodiments, the sub-blade panels (1086) may be vertically pivoted or pivoted at an angle and may be divided into one per column. In yet another embodiment, there may be multiple sub-blade panels (1086) in each row and each column (e.g., a chessboard), wherein each sub-blade panel or multiple sets of sub-blade panels (1086) operates independently. Furthermore, one or more sub-blade panels (1086) are made of materials selected from, but not limited to, metals, non-metals, alloys, polymers, fibers, glass, ceramics, wood, or combinations thereof. The blade panel assembly (108) itself is novel and inventive because it can also be used to modify existing wind turbines to provide improvements.
[0049] As previously described, the auxiliary control device (110) is configured to facilitate pivoting motion of one or more sub-blade panels (1086). In this sense, the auxiliary control device (110) is selected from, but is not limited to, one or more of the following: cam and follower mechanisms, servo motors, belt and pulley mechanisms, chain and sprocket mechanisms, gear mechanisms, linear and rotary actuators (1066), lever mechanisms, centrifuges, hydraulic systems, pneumatic control, numerical control, stepper motors, electromagnetic motors, electromagnets, screw actuators, groove readers, digital and analog control, or combinations thereof.
[0050] In addition, the system (100) includes one or more sensors (not shown) in conjunction with an auxiliary rotating shaft (1084), a mounting device (1082), one or more sub-blade panels (1086), and one or more output drive rotors (102). The one or more sensors include, but are not limited to, orientation sensors, velocity sensors, accelerometers, gyroscope sensors, magnetometers, groove readers, protrusion readers, optical readers, pressure sensors, radiation sensors, perforated disk readers, magnetic sensors, anemometers, Hall effect sensors, or combinations thereof. These sensors can be arranged anywhere in the system (100) where they are needed, depending on where the system (100) is implemented.
[0051] exist Figure 1A-1CIn the exemplary embodiment shown, the auxiliary control device includes a control lever, a motor (110), a rotary actuator, and a lever mounted on each mounting device (1082). The control lever is connected to each of one or more sub-blade panels (1086), and a servo motor is connected to the control lever. The servo motor moves the control lever, and the control lever sequentially moves each of one or more sub-blade panels (1086) to fully open, partially open / close, or fully close them.
[0052] In addition, as previously mentioned during the main control unit (106), the system (100) also includes a main control unit (MCU (112)). According to embodiments of the invention, the MCU (112) is typically disposed between one or more arm structures (104) and one or more output drive rotors (102). In other embodiments involving multiple output drive rotors (102) and more than one MCU (112), there may be respective MCUs (112) and each output drive rotor (102) (and its connected components). Besides the main control unit (106), the MCU (112) may also include or be connected to a processing module (not shown). Figure 1A Similar embodiments to the illustrated one have only one output drive rotor, and the processing module can be housed in the housing (202) along with the cam and follower (1062). In other embodiments involving multiple output drive rotors (102) and more than one MCU (112), a processing module can be placed in each MCU (112), or there can be a centrally located processing module for the entire system. The MCU (112) with the processing module is connected to one or more sensors, one or more primary control devices (106), and one or more secondary control devices (110). The processing module is capable of receiving input from one or more sensors, input devices, or external connections such as LAN / WAN, the Internet, etc., and is also capable of sending input to one or more primary control devices (106) and, based on the received input, one or more auxiliary control devices (110) and direction control devices.
[0053] The processing module (not shown) may include computing power, such as a memory cell configured to store machine-readable instructions. The machine-readable instructions may be loaded into the memory cell from a non-transitory machine-readable medium such as, but not limited to, CD-ROMs, DVD-ROMs, and flash memory drives. Alternatively, the machine-readable instructions may be loaded into the memory cell in the form of a computer. The memory cell in this manner may be selected from the group consisting of EPROMs, EEPROMs, flash memory, etc. Furthermore, the processing module includes a processor operatively connected to the memory cell. In various embodiments, the processor may be, but is not limited to, ARM-based or multi-core-based processors in the form of field-programmable gate arrays (FPGAs), general-purpose processors, and application-specific integrated circuits (ASICs).
[0054] In another embodiment, the processing module may be a microcontroller. A microcontroller may include one or more CPUs (processor cores), as well as memory and programmable input / output peripherals. The chip typically also includes program memory in the form of ferroelectric RAM, NOR flash memory, or OTP ROM, and a small amount of RAM. In yet another embodiment, the processing module is a microprocessor.
[0055] A microprocessor can be a versatile, clock-driven, register-based digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides the result as output. A microprocessor can contain combinational and sequential digital logic and can operate like an SBC (System-on-a-Branch). In yet another embodiment, the processing module can be a remotely connected external interface with control functions, processing data loaded from an external network.
[0056] Furthermore, the system (100) includes an output device (114) connected to one or more output drive rotors (102), such as Figure 1A-1B As shown. The output device (114) may be positioned on one or more platforms (1202) on the base. The output device (114) is configured to convert the rotational torque of one or more output-driven rotors (102) into one or more forms of energy. Depending on the application, the form of energy may be electrical, mechanical, etc. In this sense, one or more output devices (114) may include generators (for generating electrical energy) or gears, belts, chains, pumps, etc., for generating mechanical energy. The output device (114) may also include hardware for manufacturing accessories and fixing devices, and various kinds of bearings and friction-reducing accessories, ratio converters (for increasing / decreasing rotor rotation as needed), and direction converters using gears and belts or other methods.
[0057] Simply put, the output device (114) is envisioned to include all infrastructure, including auxiliary equipment for energy conversion or energy transfer from one point to another within the system (100), at the site, or elsewhere.
[0058] like Figure 1A-1C The operation of the embodiment (vertical axis) of the drag-based wind turbine system (100) shown:
[0059] As described above, this invention can utilize maximum wind energy ranging from a few miles per hour to hundreds of miles per hour without causing any damage to its structure (even in cyclones). This is achieved using two unique and innovative features of this invention, namely...
[0060] (1) Blade panel assembly (108) rotates dynamically and individually on its own axis according to its angular position during each rotation of the rotor to optimize forward drag and lift while reducing reverse drag;
[0061] (2) The pivotable blade panel (1086) of the blade panel assembly (108) is pivotable (open / close) to change its contact area with the wind and allow excess wind to pass through the panel assembly and prevent any damage in high-speed wind.
[0062] The operation method using the above features will now be described in detail. (Reference) Figure 1A In this embodiment, it is assumed that the wind flows in a forward direction (indicated by the white arrows outlined in black). There are four arms (104), each connected to a blade panel assembly (108) (therefore, four blade panel assemblies (108)). The auxiliary rotation axis (1084) of the blade panel assembly (108) is supported by the corresponding arm structure (104) and controlled by the main control device (106). Thus, each blade panel assembly (108) is configured to rotate 0-270 degrees about the auxiliary rotation axis (1084), but is not limited to 0-270 degrees. However, if a motor is used as the main control device (106) between the corresponding arm structure (104) and the auxiliary rotation axis (1084), 360-degree rotation of the blade panel assembly (108) is also possible.
[0063] Even before the system (100) begins operation, it is clear that certain conditions, such as wind flow, may or may not cause the blade panel assembly (108) to rotate due to the flowing wind. Therefore, if a certain force is applied to each blade panel assembly (108), the four arms (104) will be in a certain angular position, and so on. Therefore, these parameters need to be determined first. Thus, the processing module dynamically determines, but is not limited to, wind direction, wind speed, the rotational speed of one or more output drive rotors (102), the individual angular positions of one or more arms, and the force applied to each blade frame (1082) using one or more sensors.
[0064] Furthermore, based on the wind direction, the required rotation direction for the application, and the force on each blade panel assembly (108), a processing module using one or more sensors is configured to determine the point of maximum thrust on the system (100), i.e., the point of maximum force that causes the system (100) to rotate in the desired direction.
[0065] For example, such as Figure 1C As shown (top view of system (100)), the required rotation is counterclockwise (as indicated by the thick black arrow), and the maximum resistance is on the blade panel assembly (108) on the right (as shown).
[0066] The drag on the rightmost blade panel assembly (108) causes the system (100) to rotate counterclockwise with the wind. To maximize forward thrust while minimizing reverse drag, the angle of attack on the other three panels is continuously adjusted to the optimal position by the MCU (112). Figure 1C Continuing, the leftmost blade panel assembly (108) is most likely to experience reverse drag and cause counterclockwise rotation when moving against the wind. Therefore, its contact area with the wind can be minimized by orienting the left blade. The blade panel assembly (108) is parallel to the wind direction or slightly inward / outward to generate some possible forward lift. Similarly, the front and rear blade panel assemblies (108) (as shown in the diagram) Figure 1C The blades (shown at the bottom and top) are oriented to generate forward drag and / or lift to increase torque from the corresponding arm (104). The direction is counter-clockwise (instead of any other direction). It is important to note that both blades generate lift and drag, and although the lift is perpendicular to the wind direction but synchronized with the counter-clockwise rotation, both forces are additive. All the above parameters are dynamically determined by the MCU (112) (with a processing module) with the aid of one or more sensors. Additionally, it is important to note that the term "dynamically determined" is used to indicate that all the above parameters are determined continuously during each rotation, not just once. This provides better control of the system (100) to achieve the desired results.
[0067] The MCU (112) is configured to dynamically adjust the angle of attack of each mounting device (1082) during each rotation, and repeat this process with each rotation. Therefore, as Figure 1C As shown, each of the four blade panel assemblies (108) continues to gradually exchange their positions at an optimized angle of attack by rotating around their respective auxiliary rotation axes (1086) using a controlled master control unit (106) to achieve the desired orientation for optimized positive torque. Figure 1C The positions of the four blade panel assemblies (108) shown are symbolic; for example, when the arm (104) rotates 90 degrees counterclockwise, the right blade panel assembly (108) moves to the position (topmost as shown). Figure 1C As shown), the next one moves to the left, and the left one moves forward (as shown at the bottom). Figure 1C As shown), the panel moves to the right next / nth position, and there are n other intermediate positions within the 360-degree turn. The panel repeats these positions sequentially under the control of (various types) MCUs.
[0068] It should be noted that when the left side (in) Figure 1C When the blade panel assembly (108) moves to the front (i.e., the bottom position), it will rotate and change its angle of attack by approximately 100 degrees. This 120 degrees ± 50 degrees shifts from an inward direction to an outward direction, as previously held in the front blade panel. This sudden rotation occurs at a pre-programmed rotation position where the reverse thrust is minimal and its duration is shortest. The main control unit (MCU (112)) can be used as follows... Figure 2B The above-mentioned functions are facilitated by a simple groove reader or a main control device (106) with a complex electronic controller (not shown) that is programmed.
[0069] In the exemplary embodiment shown, the main control device (106) includes a cam follower in the form of a groove reader (1062), a control lever (1064), a linear actuator, a rotary actuator (1066), etc. Reference Figure 2B and 2C As can be seen, the cam's profile is accompanied by a groove throughout most of the rotation, slowly moving away from the center for most of the rotation, and then suddenly moving inward and completing a full rotation in a very small portion of the rotation. Here, Figure 2B It depicts the wind direction from west to east and the position of contour lines 2C from north to south, among which... Figure 1A -C indicates the blade assembly position from south to north wind direction. As previously described, the follower (206) rotates around the profile of the cam (204) in a groove surrounding the cam (204) and is further attached to the control lever (1064).
[0070] The movement of the panel and arm forces the follower (206) to move in the groove, the shape of which causes a back-and-forth (linear) motion in the control lever (1064), which forces the blade panel assembly to move through the linearly optimized angle of attack of the panel and the rotary actuator (1066).
[0071] It should be noted that different portions of the cam (204) profile are responsible for causing the rotation of the blade panel assembly (108). For example, a sudden tilt can cause a large rotation of the blade panel assembly (108), such as the approximately 120° ± 50° rotation required for the leftmost blade panel assembly (108) to reach the bottom blade position. Therefore, the absolute positioning of the cam (204) plays a significant role in wind direction. Let's assume that if the wind direction is opposite to the tilt angle of the cam profile, then it would require... Figure 2B Similarly, on opposite sides, because the desired orientation of each blade panel assembly (108) will change by 180 degrees at that location. Therefore, after detecting / determining the change in wind direction, the MCU (112) uses... Figure 1B The drive gear (1070) and control gear (1068) shown rotate the cam assembly (202) in the desired direction by a small motor (not fully visible in the figure).
[0072] It should be noted that the above-mentioned components and the method by which they cause one or more blade panel assemblies (108) to rotate are examples of mechanical master control devices (106).
[0073] In other words, using the above-described components and methods, a technician can implement an automatic or semi-automatic dynamic rotation mechanism for one or more blade panel assemblies (108). However, the aforementioned mechanical devices can be replaced by electrical, electronic, hydraulic, or pneumatic components such as motors (e.g., stepper / servo motors, pistons, etc.) to easily reduce the number of components used while still performing the dynamic angle of attack change mechanism. In addition to these, other devices mentioned in the list of primary / secondary control devices (106) can also be used without departing from the scope of the invention.
[0074] Furthermore, please note that the term "optimization" as used in this specification is contemplated to cover both increasing and decreasing forward drag and lift, as it may be necessary to reduce forward drag in certain situations. Therefore, the present invention is also capable of doing so.
[0075] According to embodiments of the invention, situations such as storms may occur where wind speeds exceed the overall design goals of the wind turbine system (100). For example, a wind speed of 50 m / s is considered too high for any existing wind turbine to generate torque. Therefore, in such scenarios, the invention provides a unique capability to allow dangerously high-speed winds through the blade panel assembly (108) by properly opening all sub-blades to allow wind to pass through rather than impact it. This capability enables the invention not only to avoid damage but also to maintain energy generation even under such harsh environmental conditions.
[0076] This is because each blade panel assembly (108) of the present invention is itself made of one or more pivotable sub-blade panels (1086) (see Figure 3).
[0077] continue Figure 1A For example, when the wind speed exceeds a predetermined limit (as sensed by the system (100)), the MCU (112) is further configured via a processing module to adjust the opening of one or more sub-blades using the panel of one or more auxiliary control devices (110). This allows wind to pass through the blade frame (1082) without any restriction (which will be visible once the blade frame (1082) is fully open).
[0078] The auxiliary control device (110) not only reduces reverse drag but also regulates and smooths torque during gusts and protects the system (100) from abnormal speeds. Furthermore, it ensures reliable and optimal capacity output even under conditions of highly variable wind speeds without interruption, while preventing any damage to the system (100).
[0079] The ability of one or more sub-blade panels (1086) to not only open or close but also partially open allows the invention to be used in a variety of situations other than high-speed winds. This enables the invention to withstand gusts and still produce a constant output. For example, in the case of gusts, the wind speed increases irregularly for a few seconds as the wind rushes in. This change is typically noted to be within 20% of the wind speed increase / decrease. This 20% excess wind force can cause the turbine system to be overloaded by more than 170% during these offsets. Although the duration is short, this creates ripples in power generation, and if it continues for a longer period, it can damage or permanently destroy the power generation equipment.
[0080] Because the wind turbine system (100) of this invention can begin generating electricity at low wind speeds of approximately 3 meters per second or less, it will quickly reach its rated full capacity at moderate wind speeds of 10 to 20 meters per second. In areas with good wind speeds, wind speeds can exceed 20 meters per second, and it is common for them to reach 30 to 40 meters per second. In this system (100), one or more sub-blade panels can be partially opened to regulate the output to maintain optimal constancy. Therefore, this invention can control one or more sub-blades to produce a constant output exceeding its designed optimal full-load wind speed, reaching, but not limited to, 80 meters per second or higher.
[0081] This design can maintain and control the output torque from the turbine system (100) to keep it at the design maximum, with wind speed variations up to ten times the optimal speed.
[0082] According to another embodiment of the invention, the system (100) can also be implemented as a horizontal axis drag-based wind turbine system (100). This embodiment has been... Figure 4A and 4B As shown in [the image]. This embodiment is intended to cover [the specific context]. Figure 1A-1C The broader aspects discussed but not shown include, for example, the horizontal (or angular) direction, multiple output drive rotors (102), multiple arm structures (102) at both ends of the output drive rotors, a central or individual MCU (112), etc. All components and operating principles used in this embodiment are consistent with... Figure 1A The vertical axis implementation is the same, only the number of components and design are different.
[0083] like Figure 4A As shown, there exists a wind turbine system (100) based on horizontal axis drag, mounted on a foundation structure (120). As previously described, the foundation structure (120) may be, but is not limited to, a tower, column, etc., having one or more legs (1204) and one or more platforms (1202) to accommodate components of the system (100). In this embodiment, the output device (114) is arranged on top of the foundation structure (120). This embodiment illustrates one or more output drive rotors (102) (e.g., two, such as...). Figure 4A (As shown in the series arrangement), each output drive rotor is connected to the output arrangement (114) via its own MCU (112) and primary on either side of the control device (106), such as gears, shafts, pulleys, sprockets, etc., for transferring rotational energy from one or more output drive rotors (102) to the output device (114) (in this case, a generator).
[0084] The processing modules can be centrally located or placed within individual MCUs (112). Additionally, one or more arms (104) (e.g., such as...) Figure 4AThe four (plus four) shown extend radially (90 degrees apart) from both ends of each of the two output drive rotors (102) (effectively separating the panels by 45 degrees).
[0085] Furthermore, one or more arms (104) are connected to corresponding blade panel assemblies (108). This embodiment differs from the vertical axis arrangement here, where two parallel arms (104) mount the blade panel assemblies (108) instead of a single arm structure in a vertical axis design (a similar arm structure could also be used). Similarly, each blade panel has an auxiliary rotation axis (1086) that can be rotated using a main control unit (106) and one or more sub-blade panels (1086), and that can be pivoted using an auxiliary control unit (110). Thus, the design of a wind turbine system (100) based on horizontal axis drag and lift could resemble either side of two parallel wind turbine output units (114) (showing a 45-degree offset between the sides, or up to ±180 degrees if required).
[0086] It can be seen that the output device (114) is placed in the outer casing (e.g., Figure 4A On the box-shaped housing shown, two MCUs (112) are connected from the side of the housing. Similar to the vertical axis arrangement, the box-shaped housing is connected to a gear assembly for rotating the entire wind turbine arrangement according to the wind direction. For example, the wind direction currently shown is perpendicular to the top blade panel assembly (108), but if the wind direction becomes axial relative to one or more output drive rotors (102), the entire wind turbine assembly can be rotated 90 degrees so that the wind direction always remains perpendicular to the top blade panel assembly (108).
[0087] The operation method also follows the same steps as the vertical axis system (100).
[0088] like Figure 4B As shown, the wind flows from left to right and the desired rotation direction of one or more output drive rotors (102) is clockwise. Again, the MCU (112) and processing module dynamically determine the wind direction, wind speed, rotational speed of one or more output drive rotors (102), the individual angular position of one or more arms relative to the point of maximum thrust, and the force applied to each mounting device (1082) using one or more sensors. Therefore, to maximize forward drag and lift, the upper blade assembly (such as...) Figure 4B (As shown) is oriented in a certain way to provide the maximum possible area and the optimal angle of attack (angle of attack) of up to 90 degrees.
[0089] For example, the topmost blade panel assembly (108) remains perpendicular to the wind direction to provide maximum area for generating forward drag and allowing the panel to move with the wind, while the bottommost blade, moving against the wind, remains parallel to the wind direction to provide minimum area for the wind and minimize reverse drag. Similarly, all or one blade panel assembly (108) is configured to acquire a predetermined orientation at a specific location during rotation to optimize (increase or decrease) the angle of attack and increase forward drag and / or lift while reducing reverse drag during rotation. Partial rotation against the wind, based on the predetermined rotation position of each blade panel assembly (108).
[0090] Furthermore, similar to the vertical axis system (100), if wind speed increases, one or more auxiliary control devices (110) are used to adjust the opening of one or more sub-blade panels to reduce forward thrust by decreasing the effective area. The blades contact the wind, regulating and smoothing torque during gusts and protecting the system (100) from speeds exceeding design limits. This ensures reliable and optimal full-capacity output without interruption, while preventing any damage to the system (100).
[0091] Those skilled in the art will understand that the above embodiments can readily operate with a single output drive rotor (102) and four arms located on one side of the output device (114). However, a dual arrangement has just been shown to demonstrate how multiple output drive rotors (102) and turbines can be combined to form a single system (100). Similarly, without departing from the scope of the invention, many such arrangements are possible, with an even greater number of output drive rotors (102) and series / parallel connections, as well as arms decreasing or increasing on each side.
[0092] Figure 4A and 4B One advantage of the illustrated embodiment is that the two sets of components on either output drive rotor (102) can be configured independently or complement each other, while providing physical balance for the entire structure. For simplicity, the figure appears to show two sets on a single rotor.
[0093] Regardless of the implementation method, whether it is the vertical axis, the horizontal axis, or the angle between the two, the two novel and inventive features of the present invention can cover each other in case of failure. Therefore, the following features illustrate the flexibility and troubleshooting capabilities of the invention without interrupting its operation:
[0094] For example, in another embodiment, the pivoting action of one or more sub-blade panels (1086) allows the invention to operate without a dynamic rotation mechanism of the MCU (212) controlling each blade panel assembly (108). This can occur when the rotation of the blade panels on the auxiliary rotation axis (1086) is not functioning or when there is a problem with the rotation actuator (1066) in any or all of the blade panel assemblies (108). In that case, any or all of the faulty blade panel assemblies (108) or components can be held in a straight position protruding in series with the corresponding arm structure (104). In this embodiment, the auxiliary control mechanism closes the sub-blade panels and opens all sub-blades during motions where wind generates maximum resistance, and on all panels during upwind rotations to maximize forward drag and minimize reverse drag. This can be done if the rotation mechanism of any one or two or all of the blade panel assemblies (108) is not functioning.
[0095] Similarly, in another implementation, adverse weather conditions may exist where high-speed winds exceed the optimal design limits of the system (100) and the pivotable action of the sub-blade panels (1086) is ineffective. Therefore, in that case, to prevent any damage to the system (100) without interrupting energy production, the system (100) configures the blade panel assemblies (108) to dynamically rotate them and orient them at the desired minimum angle of attack to maintain rotation in the desired direction. In this case, all blade panel assemblies (108) can be oriented in a position substantially parallel to the wind direction. The term "substantially" is used herein to indicate that a small angle will exist to generate forward drag to keep the turbine and system (100) running. Furthermore, it should be noted that this can be easily accomplished if the main control unit (106) is a servo motor, a stepper motor, or any other motor capable of dynamically rotating the auxiliary rotating shaft (1084). This can also be done if any one, two, or all of the pivotable sub-blade panels (1086) of the blade assemblies are not operational or in use. This implementation may be helpful when the invention is used with a conventional blade panel (without a pivotable sub-blade panel (1086)).
[0096] In addition to all the descriptions above, the following are some operational differences compared to existing technologies:
[0097] • Compared to the axial design in existing technologies, the airflow is tangential to the rotation of the main rotor;
[0098] • Compared to lift in existing technology designs, rotor thrust is generated primarily by drag;
[0099] • Compared to the right-angle drag in existing technology designs, drag and lift are additive in the direction of rotation;
[0100] • Compared to existing technology designs, the area swept by the blade is much smaller for the same output;
[0101] • The ratio of total thrust to output on the tower was much better during the invention process;
[0102] • Compared to a single blade in existing technology designs, the blade panel assembly is made of many sub-blade panels;
[0103] • Compared to existing designs where the pitch of all blades varies to adapt to wind speed, even at a constant wind speed, the absolute angle of each blade panel assembly can vary by as much as 270 degrees or more in each rotation.
[0104] • Compared to existing technology designs, wind turbine blade panels are easier to manufacture, install, and transport;
[0105] Any one or both of the primary and secondary control devices of the present invention enable the invention to function and achieve higher output.
[0106] This invention also offers many advantages over the prior art:
[0107] 1. Ultra-high energy output per square meter of scanning area;
[0108] 2. Lightweight turbine design;
[0109] 3. On-site manufacturing and assembly are very easy;
[0110] 4. Even ultra-high power, large turbines utilize components of easily manageable size;
[0111] 5. Easily transport materials to difficult site locations using smaller parts;
[0112] 6. Maintenance does not require highly specialized infrastructure;
[0113] 7. Effective energy production begins at low wind speeds (even below 5 km / h);
[0114] 8. Even with wind speeds exceeding 200 km / h, it can generate electricity while standing upright without causing any damage to the system or interrupting power generation;
[0115] 9. Built-in protection against cyclone wind speeds eliminates the need to shut down power generation;
[0116] 10. No safety braking mechanism required;
[0117] 11. In a vertical rotor design, rotational energy can be easily transferred to the ground;
[0118] 12. Energy harvesting has multiple applications in vertical rotor design.
