Description

Technical Field

[0001] This application relates to the field of wind power generation, and more specifically, to a vertical wind turbine with a clutch. Background Technology

[0002] In existing technologies, during wind power generation, the wind turbine's power generation components are always connected to the main shaft. That is, when the main shaft rotates, it drives the power generation components to rotate and generate electricity; when the main shaft stops, it stops generating electricity. This makes it difficult to independently control the state of the power generation components, resulting in low controllability of the power generation process. Summary of the Invention

[0003] The purpose of this application is to provide a vertical wind turbine with a clutch, which can control the state of the power generation components according to the actual power generation needs, thereby improving the controllability of the power generation process.

[0004] The embodiments of this application are implemented as follows:

[0005] This application provides a vertical wind turbine with a clutch, including a wind turbine assembly, a clutch, and a power generation assembly. The wind turbine assembly includes a main shaft and a blade assembly. The blade assembly is configured to drive the main shaft to rotate when exposed to wind. The main shaft is provided with a first gear, which is configured to rotate synchronously with the main shaft. The clutch includes a clutch gear set and a drive assembly connected to the clutch gear set. The drive assembly is configured to drive the clutch gear set close to and engage with the first gear, or to drive the clutch gear set away from and disengage from the first gear. The power generation assembly is connected to the clutch gear set and is configured to rotate synchronously with the clutch gear set and generate electricity.

[0006] In the above technical solution, the clutch gear set can mesh with the first gear on the main shaft, and the drive component can drive the clutch gear set to move closer to or away from the first gear. At the same time, the power generation component is connected to the clutch gear set. Through the cooperation of the clutch gear set and the drive component, the connection or disconnection of the power generation component and the main shaft can be realized, thereby improving the controllability of the power generation process.

[0007] In some alternative embodiments, the clutch gear set includes a second gear and a third gear that are always meshed with each other. The second gear is connected to a drive assembly, and the third gear is connected to a power generation assembly. The drive assembly is configured to drive the second gear toward and mesh with the first gear, or to drive the second gear away from and disengage from the first gear. The power generation assembly is configured to rotate synchronously with the third gear and generate electricity.

[0008] In the above technical solution, the clutch gear set includes a second gear and a third gear that are always meshed with each other. The second gear is connected to the drive component, and the third gear is connected to the power generation component. This arrangement allows the drive component to connect or disconnect the power generation component from the main shaft simply by driving the second gear, which is not connected to the power generation component. Since the second gear exists independently, it does not have to bear the pressure from the power generation component, which makes the clutch safer and more stable during movement. At the same time, it is less likely to damage the wind turbine structure.

[0009] In some alternative implementations, the number of teeth on the second gear corresponds to the number of teeth on the third gear, and the number of teeth on the second gear is 1 / 8 to 1 / 4 of the number of teeth on the first gear.

[0010] In the above technical solution, setting the tooth number relationship of the second and third gears in the above form enables them to have a suitable tooth number ratio so as to drive the power generation component to generate electricity; setting the tooth number relationship of the second and first gears in the above form enables them to have a suitable tooth number ratio so as to have high transmission efficiency and thus improve power generation efficiency.

[0011] In some alternative implementations, an elliptical limiting hole is provided at the position corresponding to the shaft of the second gear on the base of the clutch. The elliptical limiting hole is configured to ensure that the second gear can always mesh with the third gear during movement.

[0012] In the above technical solution, setting an elliptical limiting hole to restrict the movement trajectory of the second gear can easily achieve the purpose of the second gear always meshing with the third gear during the movement process. At the same time, this limiting method also has the advantage of a relatively simple structure of the trajectory limiting unit.

[0013] In some alternative embodiments, the shaft of the second gear is housed within an elliptical limiting hole, and during movement, the shaft of the second gear moves along the extending direction of the inner wall of the elliptical limiting hole.

[0014] In the above technical solution, the second gear and the elliptical limiting hole are engaged in the manner described above, which has the advantage of a relatively smooth movement process.

[0015] In some alternative embodiments, a fourth gear is provided on the shaft of the third gear, the fourth gear being configured to rotate synchronously with the shaft of the third gear, and the power generation component includes a fifth gear and a power generation device connected to the fifth gear, the fifth gear being configured to always mesh with the fourth gear and be able to drive the power generation device to generate electricity.

[0016] Optionally, the number of teeth of the third gear is 1 / 4 to 1 / 2 of the number of teeth of the fourth gear, and the number of teeth of the fourth gear is 2 to 4 times the number of teeth of the fifth gear.

[0017] In the above technical solution, the power generation component and the adjacent third gear adopt a gear transmission form. At the same time, the internal structure of the power generation component also adopts a gear transmission form, which enables the power generation component to have advantages such as simple transmission structure, high transmission efficiency and relatively stable power generation process.

[0018] Furthermore, by limiting the gear ratios of the third and fourth gears and the fourth and fifth gears to the aforementioned ranges, the entire transmission system of the power generation unit can achieve high transmission efficiency, thereby enabling the power generation unit to achieve high power generation efficiency.

[0019] In some alternative implementations, the drive assembly includes a linear drive and a connector, the end of the connector near the linear drive being connected to the power output end of the linear drive, and the end of the connector away from the linear drive being connected to a second gear, the linear drive being configured to drive the connector toward or away from the first gear.

[0020] Alternatively, the linear drive can be a cylinder, a hydraulic cylinder, or an electric actuator.

[0021] In some alternative embodiments, the drive assembly includes a lead screw nut disposed on the base of the clutch, a lead screw passing through the lead screw nut, and a rotary drive member, one end of the lead screw being connected to a second gear and the other end of the lead screw being connected to the rotary drive member, the rotary drive member being configured to drive the lead screw and the lead screw nut to rotate relative to each other so that the lead screw can move closer to or away from the first gear.

[0022] In the above technical solution, the driving component can be either linear or rotary, giving it multiple driving forms and thus multiple implementation options, thereby improving its compatibility. Furthermore, in the linear driving form, the linear driving element can also take on multiple different forms, giving it multiple implementation options and further improving its compatibility.

[0023] In some alternative implementations, the blade assembly includes a plurality of wind turbine blades and a plurality of first connecting rods, one end of each first connecting rod being connected to a wind turbine blade and the other end of each first connecting rod being connected to a main shaft, so that the wind turbine blades can drive the main shaft to rotate when exposed to wind, and each wind turbine blade is configured to rotate about its own axis.

[0024] In the above technical solution, the wind turbine blades can revolve around the main shaft or rotate on their own axis. Compared with the form in which the wind turbine blades can only revolve around the main shaft, this can improve the overall transmission efficiency of the wind turbine, thereby further improving the power generation efficiency of the wind turbine.

[0025] In some alternative embodiments, the vertical wind turbine also includes a transmission assembly, which includes a second connecting rod and a second and a third conical tooth disposed at both ends of the second connecting rod and rotating synchronously. A first conical tooth is rotatably sleeved on the main shaft, and a sixth gear is disposed on the shaft. The second connecting rod is rotatably connected to the first connecting rod. The first conical tooth meshes with the second conical tooth, and the third conical tooth meshes with the sixth gear. The first conical tooth is configured to satisfy the following condition: when the main shaft rotates, the first conical tooth remains stationary, so that the wind turbine blades can rotate around the shaft when exposed to wind.

[0026] In the above technical solution, the wind turbine blades can be easily rotated by setting them up in the above manner. At the same time, all transmission links in the above implementation method adopt gear transmission, which makes the transmission process have the advantages of high transmission efficiency and relatively stable transmission process.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] See Figure 1 and Figure 2 This application provides a vertical wind turbine 10 with a clutch 200, including a wind turbine assembly 100, a clutch 200, and a power generation assembly 300. The wind turbine assembly 100 includes a main shaft 110 and a blade assembly 120. The blade assembly 120 is configured to drive the main shaft 110 to rotate when exposed to wind. The main shaft 110 is provided with a first gear 111, which is configured to rotate synchronously with the main shaft 110. The clutch 200 includes a clutch gear set 210 and a drive assembly 220 connected to the clutch gear set 210. The drive assembly 220 is configured to drive the clutch gear set 210 to approach and mesh with the first gear 111, or to drive the clutch gear set 210 away from and disengage from the first gear 111. The power generation assembly 300 is connected to the clutch gear set 210 and is configured to rotate synchronously with the clutch gear set 210 and generate electricity.

[0041] In this application, the clutch gear set 210 can mesh with the first gear 111 on the main shaft 110, and the drive component 220 can drive the clutch gear set 210 to move closer to or away from the first gear 111. At the same time, the power generation component 300 is connected to the clutch gear set 210. Through the cooperation between the clutch gear set 210 and the drive component 220, the connection or disconnection between the power generation component 300 and the main shaft 110 can be realized, thereby improving the controllability of the power generation process.

[0042] It should be noted that there is no limit to the number of power generation components 300 that the main shaft 110 can drive to generate electricity when it rotates. That is, the main shaft 110 can be equipped with only one power generation component 300 or multiple power generation components 300 (equivalent to the first gear 111 being able to be connected or disconnected from one power generation component 300 or multiple power generation components 300).

[0043] As an example, along the circumference of the first gear 111, the first gear 111 is correspondingly arranged with a plurality of power generation components 300, and each power generation component 300 is correspondingly provided with a clutch 200 between it and the first gear 111.

[0044] In this embodiment, multiple power generation components 300 are provided, which can improve power generation efficiency by increasing the number of power generation components 300. At the same time, each power generation component 300 is provided with a clutch 200, which can control the number of power generation components 300 connected or disconnected from the first gear 111 according to the actual power generation needs, so that the wind turbine can generate electricity effectively under different wind conditions.

[0045] See Figure 2 As an example, the clutch gear set 210 includes a second gear 211 and a third gear 212 that are always meshed with each other. The second gear 211 is connected to the drive assembly 220, and the third gear 212 is connected to the power generation assembly 300. The drive assembly 220 is configured to drive the second gear 211 close to and mesh with the first gear 111, or the drive assembly 220 is configured to drive the second gear 211 away from and disengage from the first gear 111. The power generation assembly 300 is configured to rotate synchronously with the third gear 212 and generate electricity.

[0046] In this embodiment, the clutch gear set 210 includes a second gear 211 and a third gear 212 that are always meshed with each other. The second gear 211 is connected to the drive assembly 220, and the third gear 212 is connected to the power generation assembly 300. This arrangement allows the drive assembly 220 to connect or disconnect the power generation assembly 300 from the main shaft 110 simply by driving the second gear 211, which is not connected to the power generation assembly 300. Since the second gear 211 exists independently, it does not have to bear the pressure from the power generation assembly 300, which makes the clutch 200 safer and more stable during movement. At the same time, it is less likely to damage the wind turbine structure.

[0047] It should be noted that the gear ratios between the gears are not fixed and can be adjusted according to actual needs.

[0048] As an example, the number of teeth of the second gear 211 corresponds to the number of teeth of the third gear 212, and the number of teeth of the second gear 211 is 1 / 8 to 1 / 4 of the number of teeth of the first gear 111.

[0049] In this embodiment, setting the tooth number relationship of the second and third gears 212 in the above manner enables them to have a suitable tooth ratio so as to drive the power generation component 300 to generate electricity; setting the tooth number relationship of the second and first gears 111 in the above manner enables them to have a suitable tooth ratio so as to have high transmission efficiency and thus improve power generation efficiency.

[0050] It should be noted that, since the second gear 211 needs to be able to move back and forth while also being able to mesh with the third gear 212 during its movement, the movement trajectory of the second gear 211 is not a simple linear motion, but a curved motion with a specific trajectory. In order to achieve this function, it is necessary to limit the movement trajectory of the second gear 211.

[0051] It should be noted that the trajectory of the second gear 211 is not limited and can be determined using conventional techniques in this field.

[0052] See Figure 3 As an example, an elliptical limiting hole 230 is provided at the position corresponding to the shaft 1211 of the second gear 211 on the base of the clutch 200. The elliptical limiting hole 230 is configured to satisfy the following: the second gear 211 can always mesh with the third gear 212 during movement.

[0053] In this embodiment, an elliptical limiting hole 230 is provided to limit the movement trajectory of the second gear 211, which can easily achieve the purpose of the second gear 211 always meshing with the third gear 212 during the movement. At the same time, this limiting method also has the advantage of a relatively simple structure of the trajectory limiting unit.

[0054] It should be noted that the fit between the second gear 211 and the elliptical limiting hole 230 is not limited, as long as the trajectory limiting function can be achieved.

[0055] As an example, the shaft 1211 of the second gear 211 is housed in the elliptical limiting hole 230, and during the movement of the second gear 211, the shaft 1211 of the second gear 211 moves along the extending direction of the inner wall of the elliptical limiting hole 230.

[0056] In this embodiment, the second gear 211 and the elliptical limiting hole 230 are engaged in the manner described above, which has the advantage of a relatively smooth movement process.

[0057] It should be noted that the transmission method of the power generation component 300 is not limited, as long as it can be driven by the clutch 200 to achieve the power generation function.

[0058] As an example, a fourth gear 213 is provided on the shaft 1211 of the third gear 212. The fourth gear 213 is configured to rotate synchronously with the shaft 1211 of the third gear 212. The power generation assembly 300 includes a fifth gear 310 and a power generation device 320 connected to the fifth gear 310. The fifth gear 310 is configured to always mesh with the fourth gear 213 and drive the power generation device 320 to generate electricity.

[0059] In this embodiment, the power generation component 300 and the adjacent third gear 212 adopt a gear transmission form. At the same time, the internal transmission of the power generation component 300 also adopts a gear transmission form, which enables the power generation component 300 to have advantages such as simple transmission structure, high transmission efficiency and relatively stable power generation process.

[0060] It should be noted that the gear ratios between the gears are not fixed and can be adjusted according to actual needs.

[0061] As an example, the number of teeth of the third gear 212 is 1 / 4 to 1 / 2 of the number of teeth of the fourth gear 213, and the number of teeth of the fourth gear 213 is 2 to 4 times the number of teeth of the fifth gear 310.

[0062] In this embodiment, by limiting the tooth ratio of the third gear 212 to the fourth gear 213 and the tooth ratio of the fourth gear 213 to the fifth gear 310 to the above range, the entire transmission system of the power generation component 300 can have a high transmission efficiency, thereby enabling the power generation component 300 to have a high power generation efficiency.

[0063] It should be noted that the driving form of the drive component 220 is not limited, as long as it can drive the second gear 211 to move back and forth.

[0064] See Figure 5 As an example, the drive assembly 220 includes a linear drive 221 and a connector 222. One end of the connector 222 near the linear drive 221 is connected to the power output end of the linear drive 221, and the other end of the connector 222 away from the linear drive 221 is connected to a second gear 211. The linear drive 221 is configured to drive the connector 222 near or away from the first gear 111.

[0065] See Figure 6 As an example, the drive assembly 220 includes a lead screw nut 223 disposed on the base of the clutch 200, a lead screw 224 passing through the lead screw nut 223, and a rotary drive member 225. One end of the lead screw 224 is connected to the second gear 211, and the other end of the lead screw 224 is connected to the rotary drive member 225. The rotary drive member 225 is configured to drive the lead screw 224 to rotate relative to the lead screw nut 223 so that the lead screw 224 can move closer to or away from the first gear 111.

[0066] In this embodiment, the drive component 220 can be either linearly driven or rotary driven, giving the drive component 220 multiple drive forms and thus multiple possible implementations, thereby improving the compatibility of the drive component 220.

[0067] It should be noted that "linear drive 221" here refers to a type of drive that provides power through a linear motion trajectory.

[0068] As an example, the linear drive 221 is a cylinder, a hydraulic cylinder, or an electric actuator.

[0069] In this embodiment, the linear drive 221 has a variety of different forms, which makes the linear drive 221 have a variety of possible implementations and can further improve the compatibility of the drive assembly 220.

[0070] It should be noted that "rotational drive 225" here refers to a type of drive that provides power by converting rotation into linear motion.

[0071] As an example, the rotary drive 225 is a joystick.

[0072] It should be noted that the form of the blade assembly 120 is not limited, as long as it can drive the main shaft 110 to rotate when exposed to wind.

[0073] See Figure 1 and Figure 4 As an example, the blade assembly 120 includes a plurality of wind turbine blades 121 and a plurality of first connecting rods 122, one end of each first connecting rod 122 being connected to a wind turbine blade 121 and the other end of each first connecting rod 122 being connected to a main shaft 110, so that the wind turbine blades 121 can drive the main shaft 110 to rotate when exposed to wind, and each wind turbine blade 121 is configured to rotate about the axis of rotation 1211 of the wind turbine blade 121.

[0074] In this embodiment, the wind turbine blade 121 can revolve around the main shaft 110 or rotate around its own axis 1211. Compared to the form in which the wind turbine blade 121 can only revolve around the main shaft, this can improve the overall transmission efficiency of the wind turbine, thereby further improving the power generation efficiency of the wind turbine.

[0075] It should be noted that the distribution of multiple wind turbine blades 121 is not limited.

[0076] As an example, multiple wind turbine blades 121 are evenly spaced along the circumference of the first gear 111.

[0077] It should be noted that the form of the drive structure that drives the wind turbine blade 121 to rotate is not limited.

[0078] As an example, the vertical wind turbine 10 also includes a transmission assembly 123, which includes a second connecting rod 1231 and a second conical tooth 1232 and a third conical tooth 1233 disposed at both ends of the second connecting rod 1231 and rotating synchronously. The main shaft 110 is rotatably sleeved with a first conical tooth 112, and a sixth gear 1212 is disposed on the rotating shaft 1211. The second connecting rod 1231 is rotatably connected to the first connecting rod 122. The first conical tooth 112 meshes with the second conical tooth 1232, and the third conical tooth 1233 meshes with the sixth gear 1212. The first conical tooth 112 is configured to satisfy the following condition: when the main shaft 110 rotates, the first conical tooth 112 remains stationary, so that the wind turbine blade 121 can rotate around the rotating shaft 1211 when exposed to wind.

[0079] In this embodiment, the wind turbine blades can be easily rotated by setting them up as described above. At the same time, all transmission links in the above implementation method use gear transmission, which gives the transmission process the advantages of high transmission efficiency and relatively stable transmission process.

[0080] Based on the above structure, in order to better understand the technical solution, the revolution, rotation, and power generation principle of the wind turbine blade 121 are explained here:

[0081] Revolution principle: The wind turbine blade 121 is connected to the wind turbine main shaft 110 through the first connecting rod 122. When the wind turbine blade 121 is exposed to wind, it can transmit the driving force provided by the wind to the main shaft 110 through the first connecting rod 122, thereby driving the main shaft 110 to rotate, thus realizing the revolution of the wind turbine blade 121 around the main shaft 110.

[0082] Rotation principle: Since the first conical tooth 112 remains stationary during the rotation of the main shaft 110, the third conical tooth 1233, which meshes with the first conical tooth 112, will rotate around the main shaft 110 under the drive of the first connecting rod 122. The rotation of the third conical tooth 1233 will cause the second conical tooth 1232, which is coaxial with the third conical tooth 1233, to rotate synchronously. The rotation of the second conical tooth 1232 will cause the sixth gear 1212, which meshes with the second conical tooth 1232, to rotate synchronously. The rotation of the sixth gear 1212 will cause the shaft 1211 of the wind turbine blade 121 connected to it to rotate synchronously, thereby realizing the rotation of the wind turbine blade 121.

[0083] Power generation principle: During the rotation of the main shaft 110, the first gear 111 connected to the main shaft 110 will rotate synchronously with the main shaft 110. At this time, the drive assembly 220 will bring the second gear 211, which is always meshed with the third gear 212, closer to the first gear 111 under the limitation of the elliptical limiting hole 230, until the second gear 211 meshes with the first gear 111. Then, the second gear 211 will rotate synchronously with the first gear 111. Then, the second gear 211 will transmit the rotation to the fourth gear 213 coaxial with the third gear 212 through the third gear 212. The fourth gear 213 will further transmit the rotation to the fifth gear 310 meshing with it. The fifth gear 310 will then drive the power generation device 320 coaxial with it to rotate synchronously, thereby realizing wind turbine power generation.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
