Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and more specifically to a wind turbine rotor and its support rod structure. Background Technology

[0002] Vertical axis wind turbines are classified into horizontal axis wind turbines (directed by a horizontal axis) and vertical axis wind turbines (directed by a vertical axis) based on the spatial position of the turbine's rotating axis.

[0003] A wind turbine rotor is a vertical axis wind turbine consisting of several blades connected to a vertical axis (central axis) via support fins.

[0004] Lift-type wind turbines utilize the different shapes of the two sides of the blades. When wind blows on the blade surface, the wind speed on the outer and inner surfaces of the blades is different due to the shape of the two sides and the blade installation angle. This creates a wind speed difference between the outer and inner surfaces of the blades. As we know from fluid mechanics, when the fluid speeds on the inner and outer surfaces are inconsistent, a pressure difference is created between the two surfaces, which is lift. When a certain blade installation angle is selected (the angle between the line connecting the leading and trailing edges of the blade and the tangent of the wind turbine's rotation circle), the component of the lift force generated by the pressure difference will produce a driving torque around the center of rotation of the wind turbine, causing the wind turbine to rotate.

[0005] In existing technology, when the wind is strong, the thrust on the wind turbine increases, and its rotation speed increases accordingly. When the rotation speed of the wind turbine exceeds the rated rotation speed, it will damage the device and reduce the service life of the device.

[0006] How to effectively protect equipment in strong winds and extend its service life is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0052] The beneficial effects of this invention are as follows:

[0053] 1. In strong winds, excessively high rotor speeds can negatively impact equipment lifespan. By incorporating rotating components, when strong winds blow against the blades, the force on the windward side is significantly greater than the force on the leeward side. This causes the entire blade to rotate and change angle, mitigating the force of the wind on the blades. During rotation, a buffer device cushions the force generated and resets the blades when the wind returns to normal. This reduces equipment damage caused by excessive rotor speeds in windy weather, thus extending the equipment's lifespan.

[0054] 2. In windy weather, if the monitoring device detects that the wind turbine is rotating too fast, the drive connection device will connect to the transmission column, so that the wind turbine can drive two generators at the same time to generate electricity. This increases the load on the wind turbine and slows down its rotation speed. This further reduces equipment damage caused by excessive wind turbine rotation speed and improves the service life of the equipment. Attached Figure Description

[0069] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0070] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0071] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0072] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the communication between the inner sides of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0073] like Figure 1 As shown, the present invention discloses a wind turbine rotor, comprising: a power unit 1, a connecting unit, and a transmission unit 3;

[0074] The power unit 1 has a windward side 11 and a leeward side 12;

[0075] The connecting part is fixedly connected at one end to the leeward side 12 of the power unit 1 and at the other end to the side of the transmission unit 3. The power unit 1 can change its windward angle through the connecting part.

[0076] One power unit 1 can be fixedly connected to multiple connecting parts, so that the power unit 1 is perpendicular to the ground;

[0077] The working principle of the above technical solution is as follows: the power unit 1 is a lifting blade, which generates a force to drive the wind turbine to rotate through the wind speed difference between the windward side 11 and the leeward side 12. The connecting part can adjust the windward angle of the power unit 1 to change the wind speed difference.

[0078] The beneficial effects of the above technical solution are as follows: When the wind is strong, the wind turbine rotates too fast, which will affect the service life of the equipment; by setting the rotating component, when the wind blows towards the power unit 1, the force of the windward side 11 is too large compared with the force of the leeward side 12, so the entire power unit 1 changes its angle by rotating the rotating component, thereby reducing the force of the wind on the blades; thus, in windy weather, the equipment damage caused by the wind turbine rotating too fast is reduced, and the service life of the equipment is improved.

[0079] like Figure 2-3 As shown, in one embodiment, the power unit 1 includes: a housing and a frame structure 13, the housing enclosing the entire frame structure 13;

[0080] The frame structure 13 includes: multiple airfoil frames 131, multiple frame support rods 132, and multiple frame connecting beams 133;

[0081] Airfoil frame 131, shaped like an airplane wing;

[0082] Multiple frame support rods 132 are vertically arranged inside the airfoil frame 131, and their two ends are fixedly connected to the airfoil frame 131. The connection points are the frame connection points.

[0083] Multiple frame connecting beams 133, including a first beam and a second beam, multiple airfoil frames 131 are placed side by side, the two ends of the multiple airfoil frames 131 are respectively fixedly connected to the first beam, and the frame connection points corresponding to the multiple airfoil frames 131 are respectively fixedly connected to the second beam.

[0084] Preferably, the outer shell is made of glass fiber as the main material, and all the structures included in the skeleton structure 13 are hollow rods with a partition in the middle of the rod, which reduces weight while ensuring the strength of the skeleton.

[0085] The beneficial effects of the above technical solution are as follows: by setting the frame structure 13, the overall strength of the power unit 1 is guaranteed, the weight is reduced, and the utilization efficiency of wind energy and the service life of the equipment are improved.

[0086] like Figure 4 As shown, in one embodiment, the connecting part includes: a cantilever beam 21, a rotating component 22, a buffer limit block 23, a buffer rod 24, and a buffer device 25;

[0087] The cantilever beam 21 is fixedly connected to the rotating part 3 at one end and hinged to the rotating component 22 at the other end.

[0088] The rotating component 22 is hinged at one end to the cantilever beam 21 and fixedly connected to the leeward side 12 at the other end.

[0089] The buffer limit block 23 is fixedly connected to one end of the rotating component 22 near the power unit 1;

[0090] The buffer device 25 is rotatably connected to the cantilever beam 21 at its bottom;

[0091] The buffer rod 24 is hinged at one end to the buffer limit block 23 and connected to the buffer device 25 at the other end.

[0092] The buffer device 25 is used to buffer the force exerted when the rotating component 22 rotates.

[0093] The rotating component 22 can be fixedly connected to the leeward side 12 via one or more connecting rods to stabilize the power unit 1; for example Figure 4 The diagram shows the structure of the two connecting rods. The two connecting rods and the leeward side 12 form a triangular area, so that the power unit 1 is stably connected to the rotating part 22.

[0094] The connection positions of the buffer rod 24, the buffer limit block 23, and the buffer device 25 are on the same horizontal plane, preferably located directly above or below the cantilever beam 21 and the rotating component 22.

[0095] The working principle of the above technical solution is as follows: when the wind speed is normal or low, the buffer device 25, buffer rod 24 and buffer limit block 23 provide support, keeping the power unit 1 at an angle to drive the wind turbine to rotate; when the wind speed is high, the force of the power unit 1 increases, causing the rotating part to rotate. The buffer device 25, buffer rod 24 and buffer limit block 23 buffer the force generated by the rotation, ensuring that the equipment will not be damaged due to the power unit 1 rotating too fast.

[0096] The beneficial effects of the above technical solution are as follows: In windy weather, changing the angle of the power unit 1 reduces the speed of the wind turbine, prevents excessive speed from damaging the equipment, and improves the service life of the equipment; by setting the buffer device 25, the force of the power unit 1 during rotation is buffered, preventing excessive force from damaging the equipment, and further improving the service life of the equipment.

[0097] like Figure 5-6 As shown, in one embodiment, the cushioning device 25 includes: a device housing 251, a washer ring 252, a slider 253, and an elastic member 254;

[0098] The equipment housing 251 is rotatably connected to the cantilever beam 21 at the bottom. A limiting hole is provided on the side near the rotating component. One end of the buffer rod 24 with a limiting end 241 passes through the limiting hole and is placed inside the equipment housing 251.

[0099] The pad ring 252 is placed on one side of the limiting end 241 and wraps around the part of the buffer rod 24 placed inside the buffer device 25;

[0100] The slider 253 has a slider groove 1 2531 and a slider groove 2532 at both ends. The limiting end 241 is placed in the slider groove 1 2531, and the slider groove 1 2531 limits the limiting end 241. One end of the elastic component 254 is placed in the slider groove 2532, and the other end is fixedly connected to the equipment housing 251.

[0101] Among them, the washer ring 252 is preferably made of rubber material, and the elastic component 254 is preferably made of spring;

[0102] In the slider 253, there is a hole between slider groove 1 2531 and slider groove 2532 to reduce weight; the cross-sectional area of ​​the limiting end 241 is larger than the size of the hole; and the bottom of slider groove 2532 has a position to receive the elastic component 254.

[0103] The working principle of the above technical solution is as follows: when the wind speed is normal or low, the elastic component 254 applies force to the buffer rod 24 to keep the power unit 1 at a normal angle; when the wind speed is high, the rotating component 22 rotates, pushing the buffer rod 24 to compress the elastic component 254, thereby achieving rotation buffering of the rotating component 22. When the wind speed returns to normal, the elastic component 254 pushes the buffer rod to restore the angle of the power unit 1 to normal.

[0104] like Figure 7 As shown, based on the above-mentioned generator wind turbine, this invention discloses a support rod structure for a wind turbine wind turbine, including: a power generation device 4, a support column 5, and a base 6;

[0105] The power generation device 4 is installed on the top of the support column 5 and is fixedly connected to the support column 5;

[0106] The support column 5 is fixedly connected to the base 6 at its bottom, and the wind turbine rotor speed can be adjusted through the support column 5.

[0107] The base 6 is fixed to the wind turbine tower or the ground.

[0108] The beneficial effects of the above technical solution are: when the wind turbine speed is too fast, the support column 5 adjusts the wind turbine speed to prevent the wind turbine speed from being too fast and damaging the equipment, thereby improving the service life of the equipment.

[0109] like Figure 8 As shown, in one embodiment, the power generation device 4 includes: a housing 41, a connecting plate 42, a drive shaft 43, a generator 44, a power supply device 45, a monitoring device 46, and a connecting device 47;

[0110] The connecting plate 42 is disposed on the top of the housing 41, rotatably connected to the top of the housing 41, and fixedly connected to the bottom of the transmission part 3;

[0111] The drive shaft 43 has its upper end passing through the top of the housing 41 and fixedly connected to the connecting plate 42, and its lower end passing through the bottom of the housing 41 and fixedly connected to the connecting device 47; the drive shaft 43 is located inside the housing 41 and is equipped with a drive gear 431.

[0112] The generator 44 is fixedly connected to the bottom of the housing 41 at its bottom and has a generator shaft. The upper end of the generator shaft is rotatably connected to the top of the housing 41. The generator shaft is provided with a driven gear 441, which meshes with the driving gear 431.

[0113] The power supply device 45 is electrically connected to the monitoring device 46 and the connection device 47 respectively, and is used to supply power to the monitoring device 46 and the connection device 47.

[0114] The monitoring device 46 is electrically connected to the connecting device 47 and is used to monitor the rotational speed of the drive shaft 43 and drive the connecting device 47 according to the rotational speed.

[0115] The lower end of the transmission part 3 is provided with a connecting component, and the connecting plate 42 is fixedly connected by screws;

[0116] Among them, a bearing for fixing the drive shaft 43 is provided in the hole through the housing 41;

[0117] The power supply unit 45 includes a battery and a transformer. The battery is connected to an external power source, and the transformer is connected to a detection device and a connection device.

[0118] The detection device 46 includes a microcontroller processor and a speed measuring instrument. The microcontroller processor is electrically connected to the speed measuring instrument and the connection device 47 respectively. The microcontroller processor is equipped with a speed too fast threshold and a speed too slow threshold.

[0119] The working principle of the above technical solution is as follows: the rotation of the wind turbine drives the drive shaft 43 to rotate, and the drive gear 431 of the drive shaft 43 drives the driven gear 441 to rotate, driving the generator 44 to generate electricity; when the wind speed is high, the detection device 46 determines that the speed of the drive shaft 43 is greater than the speed too fast threshold, and the drive connection device 47 connects to the support column 5 to reduce the speed of the drive shaft 43; when the wind speed decreases, the detection device 46 determines that the speed of the drive shaft 43 is less than the speed too slow threshold, and the drive connection device disconnects from the support column 5, so that the wind turbine returns to normal operation.

[0120] The beneficial effects of the above technical solution are as follows: by setting the detection device 46 and the connecting device 47, the rotational speed of the drive shaft 43 is monitored, the connection between the connecting device 47 and the support column 5 is controlled, the rotational speed of the wind turbine is adjusted, the wind turbine speed is prevented from being damaged by excessive speed, and the service life of the equipment is improved.

[0121] like Figure 11 As shown, in one embodiment, the support column 5 has an inner cavity, inside which are disposed: a first transmission column 51, a second transmission column 52, and a torque component 53;

[0122] The connecting device 47 is located inside the cavity;

[0123] The transmission column 51 has its upper end placed inside the connecting device 47 and its lower end provided with a fixing component 54.

[0124] The transmission column 2 52 has a cavity at its upper end, and a fixing component 2 55 is provided on one side of the bottom of the cavity; the lower end of the transmission column 1 51 is placed inside the cavity, and the upper end of the part of the transmission column 1 51 placed inside the cavity is provided with a cavity limiting component 512.

[0125] Torque component 53 is installed on the part of the lower end of transmission column 1 51 that is located inside the cavity. Its upper end is fixedly connected to fixed component 1 54, and its lower end is fixedly connected to fixed component 2 55.

[0126] Among them, both transmission column 1 51 and transmission column 2 52 are hollow structures, in order to reduce weight;

[0127] Among them, the torsion component 53 is preferably a torsion spring, one end of which is fixed on the first transmission column 51 and the other end is fixed on the second transmission column 52. When the first transmission column 51 rotates, the torsion component 53 drives the second transmission column 52 to rotate.

[0128] One or more connection slots 511 can be provided;

[0129] The working principle of the above technical solution is as follows: when the detection device 46 determines that the rotation speed of the transmission shaft 43 is too fast, the drive connection device 47 is connected to the transmission column 51, and the transmission column 51 drives the transmission column 52 to rotate through the torque component 53.

[0130] The beneficial effects of the above technical solution are as follows: the speed of the transmission shaft 43 can be adjusted by connecting the connecting device 47 to the transmission column 51; during adjustment, the reaction force of the connecting device 47 is buffered by the setting of the torque component 53, which prevents the reaction force during connection from being too large and damaging the equipment, and improves the service life of the equipment.

[0131] like Figure 9-10 As shown, in one embodiment, the connecting device 47 includes: a telescopic device 472, a spring 473, a connecting block 474, and a connecting housing 475;

[0132] The transmission column 51 is located inside the connecting housing 475 and has a connecting groove 511.

[0133] The connecting housing 475 has a hollow structure at the lower end and has a second connecting groove 471, which corresponds to the first connecting groove 511.

[0134] The telescopic device 472 is electrically connected to the power supply device 45 and the monitoring device 46 respectively, and is fixedly connected to the bottom of the connecting groove 471.

[0135] Spring 473 is fixedly connected at one end to telescopic device 472 and at the other end to one end of connecting block 474;

[0136] Connecting block 474 is slidably connected to connecting groove 471.

[0137] Among them, one or more connecting slots 471 can be configured to correspond one-to-one with connecting slots 511;

[0138] The telescopic device 472 is preferably an electric telescopic pole;

[0139] Among them, the connecting block 474 has a sliding limit block, and the connecting groove 471 has a corresponding sliding groove;

[0140] The working principle of the above technical solution is as follows: When the detection device 46 determines that the rotation speed of the drive shaft 43 is too fast, it drives the telescopic device 472 to extend, pushes the spring 473 and then pushes the connecting block 474 to move. The connecting block 474 enters the connecting groove 511, completing the connection action between the connecting device 47 and the drive column 51. When the detection device 46 determines that the rotation speed of the drive shaft 43 is too slow, it drives the telescopic device 472 to shorten, and pulls the connecting block 474 through the spring 473, so that the connecting block 474 completely enters the connecting groove 471, completing the disconnection action between the connecting device 47 and the drive column 51.

[0141] like Figure 12 As shown, in one embodiment, the base 6 includes:

[0142] A partition, horizontally positioned, divides the base 6 into an upper cavity and a lower cavity;

[0143] A second drive shaft 61 is located in the upper cavity. Its upper end is fixedly connected to the lower end of the drive column 52, and its lower end is rotatably connected to the partition plate. It is equipped with a second drive gear 611.

[0144] Generator 2 63 is located in the lower cavity and its bottom is fixedly connected to the bottom of the base 6; it has generator shaft 2 62, and generator shaft 2 62 is provided with driven gear 2 621, which meshes with driving gear 2 611.

[0145] The working principle of the above technical solution is as follows: when the transmission column 52 rotates, it drives the transmission shaft 61 to rotate, thereby the driving gear 611 drives the driven gear 621 to rotate, so that the generator 63 generates electricity.

[0146] The beneficial effects of the above technical solution are as follows: the kinetic energy generated by the wind turbine is transmitted to the generator 63 on the base through the transmission column 51 and the transmission column 52 to generate electricity. While adjusting the wind turbine speed, the excess kinetic energy is utilized, thereby improving the power generation efficiency of the equipment.
