Description

Technical Field

[0001] This invention relates to the field of new energy technology, and in particular to a vertical axis wind power drive device. Background Technology

[0002] Wind energy, as a renewable energy source, has the characteristics of huge reserves, renewability, wide distribution, and no pollution, making it a globally welcomed clean energy source. Wind power generation has become the renewable energy power generation method with the most conditions for large-scale development and commercial prospects.

[0003] Wind power generation is divided into horizontal axis and vertical axis types, with horizontal axis being the most commonly used. However, with technological advancements, the disadvantages of horizontal axis wind turbines, such as noise, large size, complex structure, and poor wind resistance, have become apparent. Consequently, countries worldwide have begun to vigorously develop vertical axis wind turbines. However, due to the inability to effectively address the influence of wind speed and direction, and the low wind energy utilization rate caused by smaller blade areas, current vertical axis wind turbines are mostly limited to small and micro-sized units. The development of large-scale units is scarce. This invention provides a vertical axis wind power drive device particularly suitable for large and ultra-large generator sets. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical axis wind power drive device that effectively addresses the impact of wind speed and direction and effectively increases blade area, thereby improving wind energy utilization. The specific technical solution is as follows:

[0005] This invention provides a vertical axis wind power drive device, including a main frame, a wind turbine, a central shaft, a speed-changing pin, a speed-changing sleeve, a synchronization pin, a synchronization sleeve, a wind speed and vane indicator, and a directional drive unit; the height direction of the vertical axis wind power drive device is a first direction; the main frame is mounted on a foundation, and the main frame includes an upper crossbeam, a lower crossbeam, and support members. The upper and lower crossbeams are respectively provided with upper and lower hinges at their centers, which rotatably connect to the central shaft of the wind turbine, thereby controlling the wind turbine. Vertically mounted on the main frame; the wind turbine includes: a central rotating shaft, multiple frame beams, multiple blade groups, a speed-changing pin, and a synchronization pin; the central rotating shaft is located at the center of the wind turbine, and multiple frame beams are evenly distributed radially around the central rotating shaft; each frame beam forms multiple square windows from upper beams, lower beams, support plates, and arc-shaped partitions, and each square window has an upper shaft sleeve and a lower shaft sleeve at its center, through which a synchronously rotating blade group is hinged; the blade group includes a blade rotating shaft and a blade shaft tightly connected to the blade rotating shaft. The wind turbine comprises a fixed I-shaped blade and a driven synchronous sprocket, the driven synchronous sprocket being mounted on the blade shaft. A speed-changing pin and a synchronous pin are fixedly connected to the lower beam, and a speed-changing sleeve shaft and a synchronous sleeve shaft are respectively hinged to the lower beam. A speed-changing sleeve shaft is fixedly connected to a speed-changing gear and a first elliptical gear, and a second elliptical gear and a driving synchronous sprocket are fixedly connected to the synchronous sleeve shaft. A central sleeve shaft is hinged to the central shaft and is fixedly connected to a directional gear and a central gear. The directional driving unit includes a driving component, and the directional driving unit and the driving component are mounted on the main frame. Furthermore, the directional driving unit is connected to the directional gear, the central sleeve shaft, and the central gear via the driving component. The central sleeve shaft is connected to the speed-changing sleeve shaft and the first elliptical gear via the meshing of the central gear and the speed-changing gear. The speed-changing sleeve shaft is connected to the synchronous sleeve shaft and the driving synchronous sprocket via the meshing of the first elliptical gear and the second elliptical gear. The synchronous sleeve shaft is connected to the blade shaft via a chain drive between the driving synchronous sprocket and multiple driven synchronous sprockets. The wind turbine rotation speed ω... 30 , center sleeve shaft speed ω 11 , speed of the gearbox shaft ω 316 Synchronous sleeve shaft speed ω 314 Blade shaft rotation speed ω 321 The relationship between motion, ω 30 -ω 11 =2ω 316 =-2ω 321 (Rotation speed in a full revolution), ω 316 =-ω 314 (The instantaneous rotational speed of the elliptical gears during meshing is variable), ω 314 =ω 321 (Chain drive);

[0006] Further technical solutions include: the I-shaped blade comprises a first blade and two circular second blades, the second blades being respectively disposed on both sides of the first blade along the first direction, and the second blades being perpendicular to the first blade. The arc-shaped baffle is disposed on both sides of the I-shaped blade along the extension direction of the frame beam; the arc surface of the arc-shaped baffle is clearance-fitted with the arc end face of the second blade;

[0007] Furthermore: the vertical axis wind power drive device also includes a wind speed and wind vane, which is used to receive wind speed and wind direction information;

[0008] Furthermore: the vertical axis wind power drive device has a working area and a power unloading area, and the central sleeve shaft is provided with a main plane and a main normal index perpendicular to the main plane;

[0009] Furthermore: the arc-shaped partition is disposed between the upper and lower beams of the frame beam, and on both sides of the blade assembly along the extension direction of the frame beam, with the concave portions of the arc-shaped partition on both sides of each blade assembly facing each other;

[0010] Furthermore: the rotational speed ω of the central sleeve shaft 11 , speed of the gearbox shaft ω 316 The relationship between them is ω 11 =-2ω 316 The first and second elliptical gears are the same elliptical gears;

[0011] Furthermore: the first blade is a rectangular plate-shaped blade, and the second blade is a blade with a rounded end face;

[0012] Furthermore: the blade shaft is an extendable shaft that extends through the first direction.

[0013] The beneficial effects of this invention are:

[0014] The main plane is characterized in that when the main normal and the wind speed and wind vane are in the same direction, whenever the wind turbine frame beam coincides with the main plane, the first blade of the I-shaped blade on the frame beam in the working zone coincides with its own beam, that is, coincides with the main plane. The first blade of the I-shaped blade in the unloading zone is perpendicular to its own beam, that is, perpendicular to the main plane.

[0015] When the wind turbine is in a constant wind direction, the main normal and the wind speed vane are in the same direction, the directional drive unit and drive components are stationary, and the directional gear, central sleeve shaft, and central gear are stationary. The blade shaft rotates along with the turbine frame beam and also rotates around its own axis due to the meshing relationship between the central gear and the transmission gear, the meshing relationship between the first and second elliptical gears, and the chain drive relationship between the active and driven synchronous sprockets, driving the I-shaped blades to rotate. Subsequently, based on the characteristics of the main plane, the first blade of the I-shaped blade located on the frame beam in the working zone coincides with its own beam, i.e., coincides with the main plane. The first blade of the I-shaped blade located in the unloading zone is perpendicular to its own beam, i.e., perpendicular to the main plane. This ensures that the windward area of ​​the blade assembly in the working zone is always greater than the windward area in the unloading zone, achieving continuous rotation of the wind turbine around its central axis and maximizing wind energy utilization.

[0016] When the wind turbine changes direction, the wind speed and vane indicator changes position. The directional drive unit receives the signal from the wind speed and vane indicator and adjusts the directional gear through the drive component, causing the central sleeve shaft to rotate, making the main plane and the main normal indicator perpendicular to the wind speed and vane indicator position; the main normal indicator and the wind speed and vane indicator are in the same direction. At the same time, the central sleeve shaft drives the blade shaft to rotate, causing the I-shaped blades to rotate, through the meshing relationship between the central gear and the variable speed gear, the meshing relationship between the first elliptical gear and the second elliptical gear, and the chain drive relationship between the active synchronous sprocket and the driven synchronous sprocket. Subsequently, whenever the wind turbine frame beam coincides with the main plane that changes due to the wind speed and vane indicator, the first blade of the I-shaped blade on the frame beam in the working area coincides with its own beam, that is, coincides with the main plane. The first blade of the I-shaped blade in the unloading area is perpendicular to its own beam, that is, perpendicular to the main plane. This causes the principal plane and principal normal of the wind turbine to change with the wind direction, thereby enabling the wind turbine to rotate continuously and normally around the central axis and maximizing wind energy utilization.

[0017] The arc surface of the arc-shaped baffle is fitted with the arc end face of the second blade with a clearance fit; when the main normal and the wind speed and wind vane are in the same direction, the I-shaped blade and the arc-shaped baffle on the working area frame beam are connected together without gap along the extension direction of the frame beam, which helps to increase the working windward area; the I-shaped blade and the arc-shaped baffle on the unloading area frame beam are separated from each other, which is conducive to unloading wind and unloading power; therefore, it helps the wind turbine to continuously rotate around the central axis and maximize wind energy utilization.

[0018] When the angle between the main normal and the wind speed vane is 0° (i.e., they are in the same direction), the vertical axis wind power drive device is in the maximum wind energy utilization state corresponding to the wind speed. When the angle is 90° (i.e., they are perpendicular), the vertical axis wind power drive device is in a self-locking state and stops rotating, meaning the wind turbine has a self-locking characteristic. Utilizing this self-locking characteristic, the optimal working state of the wind turbine (such as matching the power frequency) can be obtained by adjusting the angle between the main normal and the wind speed vane. In particular, when encountering strong winds, the wind turbine can operate normally by appropriately adjusting the angle between the main normal and the wind speed vane of the central shaft using the self-locking characteristic. When maintenance or other matters require the wind turbine to stop, the self-locking characteristic can be used to stop its rotation.

[0019] The blade shaft is an extendable shaft extending along the first direction. This allows the wind turbines to be combined in multiple stages along the first direction to form a multi-stage vertical axis wind power drive device. Attached Figure Description

Detailed Implementation

[0031] like Figures 1 to 9As shown (taking 6 frame beams 31 as an example), the vertical axis wind power drive device includes a main frame 20, a wind turbine 30, a central sleeve shaft 11, a speed change pin 315, a speed change sleeve shaft 316, a synchronization pin 313, a synchronization sleeve shaft 314, a wind speed and wind vane 61, and a directional drive unit 50; the height direction of the vertical axis wind power drive device is the first direction X; the main frame 20 is set on the foundation, and the main frame 20 includes an upper crossbeam 21, a lower crossbeam 22, and a support member 23; the upper crossbeam 21 and the lower crossbeam 22 are respectively provided with an upper hinge 211 and a lower hinge 221 at their centers, which are connected by the... The upper hinge 211 and lower hinge 221 are rotatably connected to the central shaft 10 of the wind turbine 30, which vertically mounts the wind turbine 30 onto the main frame 20. The wind turbine 30 includes a central shaft 10, multiple frame beams 31, multiple blade groups 32, a speed-changing pin 315, and a synchronization pin 313. The wind turbine 30 is centrally fixed to the central shaft 10, and six frame beams 31 are evenly distributed radially around the central shaft 10. Each frame beam 31 forms multiple square windows from an upper beam 311, a lower beam 312, a support plate 317, and an arc-shaped partition 324. Each square window has a centrally located... An upper bushing 3111 and a lower bushing 3121 are hinged together to synchronously rotate a blade assembly 32. The blade assembly 32 includes a blade shaft 321, I-shaped blades 322 fixedly connected to the blade shaft 321, and a driven synchronous sprocket 46. A speed-changing pin 315 and a synchronous pin 313 are fixedly connected to the lower beam, and a speed-changing sleeve shaft 316 and a synchronous sleeve shaft 314 are respectively hinged to them. A speed-changing sleeve shaft 316 is fixedly connected to a speed-changing gear 48 and a first elliptical gear 47, and a second elliptical gear 43 is fixedly connected to the synchronous sleeve shaft 314. The wind turbine 30 is equipped with an active synchronizing sprocket 44; the central sleeve shaft 11 is hinged to the central rotating shaft 10, and the central sleeve shaft 11 is fastened with a directional gear 41 and a central gear 42; the main plane 63 and the main normal indicator 62 perpendicular to the main plane 63 are located on the central sleeve shaft 11; the main plane 63 is characterized in that: when the main normal indicator is in the same direction as the wind speed and wind vane, whenever the wind turbine 30 frame beam 31 coincides with the main plane 63, the first blade 3221 of the I-shaped blade 322 on the frame beam 31 of the working area A coincides with its own beam, that is, coincides with the main plane 63. The first blade 3221 of the I-shaped blade 322 in the unloading area B is perpendicular to its own beam, that is, perpendicular to the main plane 63.The directional drive unit 50 includes a drive component 51, and the directional drive unit 50 and the drive component 51 are mounted on the main frame 20. Furthermore, the directional drive unit 50 is connected to the directional gear 41, the central sleeve shaft 11, and the central gear 42 via the drive component 51. The central sleeve shaft 11 is connected to the variable speed sleeve shaft 316 and the first elliptical gear 47 via the central gear 42 meshing with the variable speed gear 48. The variable speed sleeve shaft 316 is connected to the synchronous sleeve shaft 314 and the active synchronous sprocket 44 via the first elliptical gear 47 meshing with the second elliptical gear 43. The synchronous sleeve shaft 314 is connected to the blade shaft 321 via the active synchronous sprocket 44 and multiple driven synchronous sprockets 46 via a chain drive 49. The blade shaft 321 is fixedly connected to an I-shaped blade 322. The central sleeve shaft rotates at a speed ω. 11 , speed of the gearbox shaft ω 316 The relationship between their motions is ω 11 =-2ω 316 The first elliptical gear 47 and the second elliptical gear 43 are exactly the same elliptical gears.

[0032] During the initial setup of the vertical axis wind power drive device, the orientation of the main normal 62 and the main plane 63 is determined. The central sleeve shaft 11 is fixed, and one of the frame beams 31 and the blade shaft 321 of the wind turbine 30 are adjusted so that the first blade 3221 of the I-shaped blade 322 coincides with the main plane 63, defined as orientation I. The six orientations are evenly distributed after one revolution around the central shaft 10. For example... Figure 3 , Figure 8 As shown, with the wind turbine 30 as the reference frame (ignoring changes in wind direction), the rotational speed ω of the central sleeve shaft 11 is... 11 Wind turbine speed 30 rpm 30 316 speed change ω of the gearbox shaft 316 Synchronous sleeve shaft 314 rotation speed ω 314 And the blade shaft rotation speed ω 321 321 The relationship between motion, ω 30 -ω 11 =2ω 316 =-2ω 321 (Rotation speed in a full revolution), ω 316 =-ω 314 (The instantaneous rotational speed of the elliptical gears during meshing is variable), ω 314 =ω 321 (Chain drive) can be obtained using a graphical method.

[0033]

[0034] like Figure 4 As shown, the windward area of ​​the first blade 3221 in the working zone A is greater than the windward area of ​​the first blade 3221 in the unloading zone B, which causes the wind energy to drive the wind turbine 30 to rotate around the central shaft 10.

[0035] like Figure 5 As shown, if the wind speed and vane azimuth 'a' changes by 60° clockwise, the directional drive unit 50 receives the signal from the wind speed and vane 61 and drives the directional gear 41 and the central sleeve shaft 11 via the drive component 51 to rotate the main plane 63 and the main normal azimuth 62 60° clockwise, aligning them with the wind speed and vane 61. The main plane 63 then rotates from azimuth I to azimuth II. Simultaneously, all blade shafts 321 rotate according to the kinematic relationship ω... 30 -ω 11 =2ω 316 =-2ω 321 (Rotation speed in a full revolution), ω 316 =-ω 314 (The instantaneous rotational speed of the elliptical gears during meshing is variable), ω 314 =ω 321 This results in a corresponding clockwise rotation (the rotation of the impeller 30, i.e., ω, is temporarily disregarded). 30 =0), that is, ω after the change 321 Angle = Existing ω 321 Corner - ω 321 The angle difference is as follows: -16° + 16° → 0° in azimuth II, -43° + 27° = -16° in azimuth III, -90° + 47° = -43° in azimuth IV, -137° + 47° = -90° in azimuth V, -164° + 27° = -136° in azimuth VI, and -180° + 16° = -164° in azimuth I. This causes the first blade 3221 of the blade group 32 at azimuth II to coincide with its corresponding frame beam, that is, the main plane 63 turns from azimuth I to azimuth II. Subsequently, whenever the frame beam 31 of the wind turbine 30 passes through azimuth II, the first blade 3221 of its I-shaped blade 322 coincides with its corresponding frame beam 31 and the main plane 63, realizing the tracking of the wind speed and wind vane 61 by the main plane 63 and the main normal 62.

[0036] like Figure 4 , Figure 9As shown, the I-shaped blade 322 includes a first blade 3221 and two circular second blades 3222. The second blades 3222 are respectively disposed on both sides of the first blade 3221 along the first direction X, and the second blades 3222 are perpendicular to the first blade 3221. The arc-shaped partition 324 is disposed between the upper beam 311 and the lower beam 312 of the frame beam 31, and is disposed on both sides of the I-shaped blade 322 along the extension direction of the frame beam 31. The concave portions of the arc-shaped partition 324 on both sides of each I-shaped blade 322 are opposite to each other. The first blade 3221 of the I-shaped blade 322 is a rectangular plate-shaped blade, and the second blade 3222 is a blade with a rounded end face 3230. Therefore, along the extension direction of the frame beam 31, the arc surface of the arc-shaped baffle 324 and the arc end face 3230 of the second blade 3222 are in clearance fit. The I-shaped blade 322 and the arc-shaped baffle 324 on the frame beam 31 in the working zone A are connected together without gap, which helps to increase the working frontal area. The I-shaped blade 322 and the arc-shaped baffle 324 on the frame beam 31 in the unloading zone B are separated from each other, which helps to unload wind and unload power. This promotes the continuous rotation of the wind turbine 30 around the central axis 10 and maximizes the utilization of wind energy.

[0037] like Figure 4 , Figure 6 As shown, when the angle between the main normal 62 and the wind speed vane 61 is 0° (i.e., they are in the same direction), the vertical axis wind power drive device is in the maximum wind energy utilization state corresponding to the wind speed; when the angle is 90° (i.e., they are perpendicular), the vertical axis wind power drive device is in a self-locking state and stops rotating, that is, the wind turbine 30 has a self-locking characteristic; by using the self-locking characteristic, the optimal working state of the wind turbine 30 (such as matching the power frequency) can be obtained by adjusting the angle between the main normal 62 and the wind speed vane 61; in particular, when encountering strong winds, the wind turbine 30 can also operate normally by appropriately adjusting the angle between the main normal 62 and the wind speed vane 61 of the central sleeve shaft 11 using the self-locking characteristic; when the wind turbine 30 needs to be stopped due to maintenance or other matters, the rotation of the wind turbine 30 can be stopped using the self-locking characteristic.

[0038] A pair of identical elliptical gears have a full-cycle transmission ratio of -1, but the instantaneous transmission ratio varies; this is beneficial for reducing the width of the arc-shaped partition 324 and improving wind energy utilization.

[0039] like Figure 7 As shown, the blade shaft 321 is an extendable shaft that runs through the first direction X, and the wind turbine 30 is combined in multiple stages along the first direction X to form a large vertical axis wind power drive device.

[0040] This invention features centralized installation of the motion mechanism and full controllability, simple and accurate motion law, few moving components, stable and reliable larger components, high strength, long life and low failure rate, smooth rotational motion and low noise, making it particularly suitable for the development and utilization of ultra-large vertical axis wind power drive devices.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
