[0022] In some embodiments, the support platform is a symmetrical platform having a center of symmetry or an axis of symmetry;

[0023] Multiple support frames are symmetrically distributed between two adjacent support platforms with a center of symmetry or an axis of symmetry.

[0029] At least two blades, arranged along the first direction;

[0030] The second connector connects each blade to the rotating shaft of the wind turbine.

[0033] The same blade is connected to multiple connecting rods to form multiple connection points; the multiple connection points are evenly distributed on the same blade.

Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0051] See Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the structure of a wind power generation device according to some exemplary embodiments, such as... Figures 1 to 4 As shown, the device includes:

[0052] At least two support platforms 1 are stacked along a first direction;

[0053] A wind turbine generator 2 and a support frame 3 are installed between two adjacent support platforms 1;

[0054] Support frame 3 connects two adjacent support platforms 1;

[0055] The wind turbine 2 is detachably connected to one of the two adjacent support platforms 1, and is spaced apart from both the support frame 3 and the other of the two adjacent support platforms 1.

[0056] In some embodiments, the support platform 1 may be circular, elliptical, polygonal, or irregular in shape. For example, the support platform 1 may be triangular, square, rectangular, or pentagonal. Here, each support platform 1 may have the same shape, or at least two support platforms 1 may have different shapes.

[0057] In some embodiments, each support platform 1 may have the same shape, and two adjacent support platforms 1 may be aligned in a first direction.

[0058] In some embodiments, the first direction can be a direction perpendicular to the ground. The rotation shaft 21 of the wind turbine 2 can be arranged along the first direction. In this case, the wind turbine 2 can be a vertical axis wind turbine 2. Alternatively, the rotation shaft 21 of the wind turbine 2 can be arranged along a second direction perpendicular to the first direction. In this case, the wind turbine 2 can be a horizontal axis wind turbine 2.

[0059] It should be noted that, with the rapid development of new energy technologies in my country, wind power generation has been widely used as a green energy source. Currently, the mainstream wind turbines on the market are divided into horizontal axis wind turbines and vertical axis wind turbines. Among them, vertical axis wind turbines are gradually being used in fields such as smart computing and public power supply due to their simple structure and convenient installation.

[0060] Although vertical axis wind turbines are becoming increasingly widely used, their inherently low wind energy conversion coefficient leads to lower power generation efficiency and higher cost per unit of electricity generated. For example, because the blade structure of an H-type vertical axis wind turbine cannot be manufactured too large, and the power generation area during operation is linearly related to the blade length, the power generation area of ​​a vertical axis wind turbine is generally small. Furthermore, the wind energy conversion coefficient of vertical axis wind turbines is generally low, resulting in a lower overall power generation efficiency compared to horizontal axis wind turbines, with an energy conversion efficiency only about half that of horizontal axis turbines. This low overall power generation efficiency leads to a significant increase in the cost per unit of electricity generated, as more turbines must be manufactured to produce the same amount of electricity. This increases the procurement and processing costs of materials such as towers, support frames, and beams, ultimately resulting in poor economic viability for vertical axis wind turbines.

[0061] The development of vertical axis wind turbines needs to focus more on high efficiency and low cost. Current research on vertical axis wind turbines mainly focuses on how to lower the starting wind speed and increase the power generation efficiency of a single turbine. For example, mechanical parameters such as the number of blades, height, and rotor diameter can be adjusted to improve the power generation efficiency of a single vertical axis wind turbine. For instance, the height of the turbine can be adjusted using a height-adjustable structure to improve the wind energy utilization efficiency. However, these technologies only improve the power generation efficiency of a single vertical axis wind turbine; the high cost remains a problem when multiple vertical axis wind turbines are used for power generation.

[0062] Based on this, in some embodiments, a first number of support platforms 1 can be stacked in a first direction, and a vertical axis wind turbine can be arranged between two adjacent support platforms 1. The first number is greater than or equal to 3. That is, the wind power generation device may include at least two wind turbines 2 stacked along the first direction, with different wind turbines 2 connected to different support platforms 1.

[0063] It should be noted that when the wind turbine 2 is a vertical axis wind turbine, at least two wind turbines 2 can be stacked along the first direction to form a steamer-type wind turbine generator structure sharing a common support platform 1 in the first direction. In this case, compared to the related technologies that use a single vertical axis wind turbine for power generation, resulting in low power output, this embodiment of the disclosure can utilize at least two wind turbines 2 to generate power together, thereby improving the power generation efficiency of the wind power generation device. Furthermore, since each wind turbine 2 is stacked vertically, the installation height of the wind turbine can be increased, allowing the wind turbine to receive better wind speed conditions at a higher position than a single vertical axis wind turbine, thus increasing the power generation of the wind turbine under better wind speed conditions. On the other hand, compared with the related technologies where a separate support structure is required for each wind turbine 2 at different heights, the embodiments of this disclosure can share multiple stacked support platforms 1 to set wind turbines 2 at different heights, thereby spreading the manufacturing cost of structural components such as support platforms and support frames, effectively controlling the cost of constructing a single wind turbine, and thus reducing the cost required to set wind turbines 2 at different heights.

[0064] In some embodiments, the support frame 3 may be a support rod, a support plate, or a support column.

[0065] In some embodiments, the width of the support frame 3 can be positively correlated with the number of support platforms 1 and / or the number of wind turbines 2. Thus, the more support platforms 1 are stacked in the first direction, the wider the support frame 3 can be used to provide stronger support, thereby improving support stability and increasing the strength of the overall support structure.

[0066] For example, the support frame 3 can be a tower, and the diameter of the tower is positively correlated with the number of support platforms 1 and / or the number of wind turbines 2. It should be noted that in the wind power generation device of this disclosure, the number of support platforms 1 and / or the number of wind turbines 2 can be expanded in the first direction via flange connection structures. If the expanded number of support platforms 1 and / or wind turbines 2 is large, the overall structural strength can be improved by increasing the diameter of the support tower.

[0067] In some embodiments, the support frame 3 can be arranged along a first direction. In this case, the arrangement direction of the support frame 3 is the same as the direction in which the support platforms 1 are stacked, thereby providing support force to the stacked support platforms 1 by means of vertical support. Alternatively, the support frame 3 can be arranged along a fourth direction, where the angle between the fourth direction and the first direction is an acute or obtuse angle. In this case, the support frame 3 between two adjacent support platforms 1 can provide support force to the stacked support platforms 1 by means of oblique support.

[0068] In one embodiment, a plurality of support frames 3 are provided between two adjacent support platforms 1, and the plurality of support frames 3 are spaced apart and surround the wind turbine generator 2 located between the two adjacent support platforms 1. In this way, a stable support space can be provided for the wind turbine generator 2 located within the enclosure of the plurality of support frames 3.

[0069] In one embodiment, the distance between the support frame 3 located on two adjacent support platforms 1 and the wind turbine 2 is greater than a predetermined distance. This allows sufficient clearance between the two adjacent support platforms 1 to allow airflow, thereby providing the wind turbine 2 with wind energy that can be used for power generation.

[0070] In some embodiments, the wind turbine 2 and the support platform 1 can be connected by threads. For example, the wind turbine 2 and the support platform 1 can be connected by a flange.

[0071] In some embodiments, the support frame 3 can be fixedly connected between two adjacent support platforms 1. For example, the support frame 3 can be welded between two adjacent support platforms 1. Alternatively, the support frame 3 can be detachably connected between two adjacent support platforms 1. For example, the support frame 3 can be threadedly connected between two adjacent support platforms 1.

[0072] In this embodiment, the wind turbine 2, positioned between two adjacent support platforms 1, can be detachably connected to one of the support platforms 1, and is spaced apart from the other support platform 1 and the support frame 3 positioned between the two adjacent support platforms 1. That is, there is no connection between the wind turbine 2 and the other support platform 1, nor between the wind turbine 2 and the support frame 3.

[0073] At this point, during the dismantling of the wind turbine 2 located between two adjacent support platforms 1, after dismantling the connection between the wind turbine 2 and one of the support platforms 1, the wind turbine 2 can be successfully dismantled from between the two adjacent support platforms 1. This reduces the difficulty of dismantling and increases the speed of dismantling. It also improves the convenience of maintenance when it is necessary to dismantle the wind turbine 2 for maintenance.

[0074] In some embodiments, see Figures 1 to 4 Wind power generation equipment includes:

[0075] The first connector 4 connects one of the two adjacent support platforms 1 to the wind turbine 2;

[0076] The wind turbine 2 and the first connector 4 are detachably connected, and / or the first connector 4 and one of the two adjacent support platforms 1 are detachably connected.

[0077] In some embodiments, the first connector 4 may be a connecting rod, a connecting plate, or a connecting column. For example, the first connector 4 may be a fan column.

[0078] In this embodiment of the disclosure, the wind turbine 2 can be disassembled from the two adjacent support platforms 1 by detaching the wind turbine 2 from the first connector 4 and / or by detaching the first connector 4 from one of the two adjacent support platforms 1. This improves the flexibility of disassembling the wind turbine 2.

[0079] In some embodiments, see Figures 1 to 4 The first connector 4 is arranged along the first direction and aligned with the rotating shaft 21 of the wind turbine 2.

[0080] In some embodiments, the first connector 4 is disposed along a first direction, and the central axis of the first connector 4 is aligned with the central axis of the rotation axis 21.

[0081] In this embodiment of the present disclosure, the first connector 4 is arranged along the first direction and aligned with the rotating shaft 21 of the wind turbine 2, thereby providing a stable support force to the rotating shaft 21 of the wind turbine 2 in the first direction through the first connector 4, thereby improving the connection stability of the wind turbine 2.

[0082] In some embodiments, see Figure 5 The first connector 4 includes a first connecting end and a second connecting end that are disposed opposite to each other;

[0083] The first connection end is connected to one of the two adjacent support platforms 1;

[0084] The second connection end is connected to the electromagnetic braking module 25 at the bottom of the wind turbine generator 2 via the first flange 27.

[0085] In some embodiments, the electromagnetic braking module 25 is connected between the second connection end and the rotating shaft 21 of the wind turbine generator 2. The electromagnetic braking module 25 is used to apply a frictional force opposite to the rotational direction to the rotating shaft 21 when the rotational speed of the rotating shaft 21 in the rotational direction is greater than a speed threshold.

[0086] In one embodiment, each wind turbine 2 is individually connected to a control module, which is used at least to detect environmental parameters of the environment in which the wind turbine 2 is located and / or state parameters of the wind turbine 2. The control module is also used to adjust the operating parameters of the wind turbine 2 based on the detected environmental parameters and / or state parameters.

[0087] In one embodiment, the first connector 4 is hollow, and the electromagnetic braking module 25 of the wind turbine 2 is connected to a control module located outside the wind turbine 2 via a first line disposed inside the first connector 4. Under the action of the control signal output by the control module, the electromagnetic braking module 25 applies a frictional force opposite to the rotation direction to the rotating shaft 21. The control module is used to detect the rotational speed of the rotating shaft 21 and outputs a control signal to the electromagnetic braking module 25 when the rotational speed of the rotating shaft 21 is greater than a speed threshold.

[0088] In this embodiment, on the one hand, the electromagnetic braking module 25 at the bottom of the wind turbine 2 and the second connecting end of the first connector 4 can be detachably connected via the first flange 27, thereby facilitating the disassembly of the wind turbine 2. On the other hand, the electromagnetic braking module 25 in the wind turbine 2 can perform emergency braking in the event of a stall, thereby improving the safety of the wind turbine 2.

[0089] In some embodiments, there are multiple support frames 3; the multiple support frames 3 are spaced apart and are all connected to the edge positions of two adjacent support platforms 1.

[0090] In one embodiment, multiple support frames 3 are evenly distributed between two adjacent support platforms 1. In this way, the support frames 3 can provide uniform support force to the support platforms 1 stacked on top of each other, thereby improving support stability.

[0091] In this embodiment, since multiple support frames 3 are spaced apart and connected to the edge positions of two adjacent support platforms 1, sufficient gaps can be reserved between the two adjacent support platforms 1 for airflow to pass through, so that the blades 22 of the wind turbine 2 set between the two adjacent support platforms 1 can rotate under the action of the airflow, thereby converting wind energy into electrical energy.

[0092] In some embodiments, each support platform 1 has multiple support edges and a support angle formed by two adjacent support edges;

[0093] Two adjacent support platforms 1 have two support edges aligned along a first direction and two support corners aligned along the first direction;

[0094] The two support corners that are aligned are connected by a support frame 3;

[0095] And / or,

[0096] The two support edges that are aligned are connected by another support frame 3.

[0097] In one embodiment, all two aligned support corners of two adjacent support platforms 1 are connected by a support frame 3, and / or all two aligned support edges of two adjacent support platforms 1 are connected by a support frame 3. In this way, the pressure can be distributed among multiple support frames 3, thereby increasing the load-bearing capacity.

[0098] In one embodiment, the support frame 3 between the two symmetrically arranged support sides is located at the midpoint of each support side. In this way, the load is evenly distributed by the support frame 3 located at the midpoint of the symmetrical sides, thereby improving the stability of the support.

[0099] In this embodiment, two support corners aligned in the first direction are connected by a support frame 3, and / or two support edges aligned in the first direction are connected by another support frame 3. This allows the support frame 3 to support the aligned edge regions of two adjacent support platforms 1 in the first direction, improving the consistency between the support direction and the orientation of the support platforms 1. Furthermore, it enhances the symmetry between the support points formed in the two aligned support platforms 1, thereby improving support stability.

[0100] In some embodiments, the support platform 1 is a symmetrical platform having a center of symmetry or an axis of symmetry;

[0101] Multiple support frames 3 are symmetrically distributed between two adjacent support platforms 1 with a center of symmetry or an axis of symmetry.

[0102] For example, the support platform 1 can be equilateral trapezoidal in shape, in which case the support platform 1 has an axis of symmetry. Alternatively, the support platform 1 can be equilateral triangle in shape, in which case the support platform 1 has a center of symmetry and an axis of symmetry.

[0103] In this embodiment of the disclosure, multiple support frames 3 can be symmetrically distributed between two adjacent support platforms 1, thereby improving the uniformity of the load on the multiple support frames 3, reducing the safety risks caused by uneven load, and improving support stability.

[0104] In some embodiments, the first connector 4 connecting the wind turbine generator 2 in the wind power generation device is located at the center of symmetry.

[0105] In some embodiments, multiple support frames 3 are symmetrically distributed between two adjacent support platforms 1, with the first connector 4 connecting the wind turbine generator 2 in the wind power generation device as the center of symmetry. Here, the support platform 1 can be a symmetrical structure or an asymmetrical structure. The first connector 4 can be located at the center of symmetry of the support platform 1 or at any position other than the center of symmetry of the support platform 1. Here, there is no need to limit the structure of the support platform 1 or the position of the first connector 4 on the support platform 1; it is only necessary to ensure that the multiple support frames 3 can be symmetrically distributed with the first connector 4 as the center of symmetry.

[0106] In this embodiment, since the first connector 4 connecting the wind turbine 2 in the wind power generation device is located at the center of symmetry, multiple support frames 3 are evenly distributed around the first connector 4 with the location of the first connector 4 as the center of symmetry. This provides a stable support space for the first connector 4 and the wind turbine 2 connected to the first connector 4. In this way, the safety of the wind turbine 2 can be ensured.

[0107] In some embodiments, the support frame 3 has a first support end and a second support end along a first direction;

[0108] The first support end is connected to one of the two adjacent support platforms 1 via the second flange;

[0109] The second support end is connected to another support platform 1 among the two adjacent support platforms 1 via a third flange.

[0110] Here, flange interfaces for connecting to flanges can be reserved at the first and second support ends respectively, so as to quickly connect the flange interfaces and the flanges connected to the support platform 1, thereby completing the connection between each support end of the support frame 3 and each support platform 1.

[0111] In this embodiment, the two support ends of the support frame 3 and the support platform 1 can be detachably connected by flanges, which facilitates the disassembly and replacement of the support frame 3 installed in two adjacent support platforms 1.

[0112] In some embodiments, the wind turbine 2 includes:

[0113] At least two blades 22 are arranged along the first direction;

[0114] The second connector 23 is connected between each blade 22 and the rotating shaft 21 of the wind turbine 2;

[0115] The third connector 24 is connected between two adjacent blades 22.

[0116] In some embodiments, the third connector 24 connecting two adjacent blades 22 includes a plurality of connecting rods, which are spaced apart. The connecting rods of the third connector 24 are arranged along a second direction, which is perpendicular to the first direction.

[0117] For example, the third connecting member 24 connecting two adjacent blades 22 includes: a first connecting rod 241, a second connecting rod 242, and a third connecting rod 243, which are sequentially spaced between the two adjacent blades 22. For example, the first connecting rod 241 can be an upper connecting rod, connecting the top ends of the two adjacent blades 22. The second connecting rod 242 can be a middle connecting rod, connecting the midpoint between the two adjacent blades 22. The third connecting rod 243 can be a lower connecting rod, connecting the bottom ends of the two adjacent blades 22. Here, the two adjacent blades 22 can be securely connected by the multiple connecting rods in the third connecting member 24.

[0118] In this embodiment of the disclosure, the connection strength of the overall structure of the wind turbine 2 can be enhanced by the second connector 23 connected between each blade 22 and the rotating shaft 21 of the wind turbine 2, and the third connector 24 connected between two adjacent blades 22.

[0119] In some embodiments, the second connector 23 connecting each blade 22 and the rotating shaft 21 of the wind turbine 2 includes: a plurality of connecting rods;

[0120] The same blade 22 is connected to multiple connecting rods to form multiple connection points; the multiple connection points are evenly distributed on the same blade 22.

[0121] In this embodiment of the disclosure, the multiple connection points formed by the multiple connecting rods of the second connector 23 and the same blade 22 are evenly distributed on the same blade 22, so that the load can be evenly transmitted between the blade 22 and the rotating shaft 21, thereby improving the service life of the connecting rods and the stability of the connection.

[0122] In some embodiments, the length of the blade 22 along the first direction is the same as the length of the rotating shaft 21 along the first direction, and the second connector 23 is disposed along the second direction; the second direction is perpendicular to the first direction;

[0123] or,

[0124] The length of the blade 22 along the first direction is different from the length of the rotating shaft 21 along the first direction. The second connector 23 is arranged along a third direction, and the angle between the third direction and the first direction is an acute angle or an obtuse angle.

[0125] In some embodiments, the second connecting member 23 connecting each blade 22 and the rotating shaft 21 of the wind turbine 2 includes a fourth connecting rod 231 and a fifth connecting rod 232; wherein the fourth connecting rod 231 is arranged along a second direction, which is perpendicular to the first direction. The fifth connecting rod 232 is arranged along a third direction, and the angle between the third direction and the first direction is an acute or obtuse angle. In this way, by providing the fourth and fifth connecting rods with intersecting directions, support forces in different directions can be provided, thereby improving the stability of the connection.

[0126] In this embodiment, on one hand, when the length of the blade 22 along the first direction and the length of the rotating shaft 21 along the first direction are the same, the blade 22 and the rotating shaft 21 can be securely connected laterally by the second connector 23. On the other hand, when the length of the blade 22 along the first direction and the length of the rotating shaft 21 along the first direction are different, the blade 22 and the rotating shaft 21 can be securely connected by oblique support. Thus, the orientation of the second connector 23 connecting the blade 22 and the rotating shaft 21 can be flexibly set to adapt to the lengths of the blade 22 and the rotating shaft 21 in the first direction, improving the flexibility of connecting the blade 22 and the rotating shaft 21.

[0127] In some embodiments, the plurality of wind turbines 2 of the wind power generation device include a first wind turbine located at a first height and a second wind turbine located at a second height; the second height is greater than the first height;

[0128] The first wind turbine has more blades than the second wind turbine.

[0129] It should be noted that, under the same conditions, the altitude of wind turbine 2 is positively correlated with the wind speed at that altitude.

[0130] In some embodiments, two adjacent support platforms include: a first support platform and a second support platform stacked above the first support platform. The first wind turbine may be a wind turbine connected to the first support platform, and the second wind turbine may be a wind turbine connected to the second support platform.

[0131] In some embodiments, the first wind turbine may be a wind turbine connected to the first support platform 1. Other wind turbines in the wind power generation device, besides the first wind turbine, may have the same number of blades.

[0132] In this embodiment, when the wind speed at the first altitude is lower than the wind speed at the second altitude, the number of blades 22 of the first wind turbine 2 at the first altitude can be greater than the number of blades 22 of the wind turbine 2 at the second altitude, thereby reducing the difference in power generation between the first and second wind turbine 2. This improves the consistency of power generation at all altitudes.

[0133] For a better understanding of the embodiments of this disclosure, see [link to relevant documentation]. Figure 5 , Figure 5 The structure of a wind turbine generator 2 is illustrated by way of example. The wind turbine generator 2 includes:

[0134] Rotation axis 21 is set along the first direction;

[0135] At least two blades 22 are arranged along the first direction;

[0136] The second connector 23 connects each blade 22 and the rotating shaft 21;
