[0003] Therefore, how to improve the support stability of the fairing bracket is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0008] Optionally, in the above-described support structure, the first support member includes a first rod and a second rod. The first end of the first rod is connected to the second connecting portion, and the second end of the first rod includes either an outer tube or an inner tube. The first end of the second rod is connected to the third connecting portion, and the second end of the second rod includes either the outer tube or the inner tube. The outer tube and the inner tube cooperate with each other, and the first rod and the second rod are capable of moving relative to each other along the axial direction of the first support member.

[0009] Optionally, in the above-described support structure, the second connecting plate further includes a reinforcing plate, one side of which is connected to the third connecting portion, and the other side of which is connected to the fourth connecting portion.

[0010] Optionally, in the above-described support structure, the first support assembly further includes a third connecting plate and a second support member. The third connecting plate is connected to the flange, the first end of the second support member is connected to the third connecting plate, and the second end of the second support member is connected to the third connecting portion.

[0012] Optionally, in the above support structure, the fairing bracket includes a first bracket, a second bracket, and a connecting frame. The two ends of the connecting frame are respectively connected to the first bracket and the second bracket. The first bracket is connected to the interior of the hub, and the second bracket is suspended outside the hub. The size of the first bracket is smaller than the size of the second bracket, and the second end of the first support assembly is connected to the second bracket. It also includes a second support component, the first end of which is connected to the second end of the first support component, and the second end of the second support component is connected to the first bracket.

[0014] The support structure provided by this utility model establishes a stable support path between the hub and the fairing support by connecting the first end of the first support component to the flange of the hub and the second end to the fairing support.

In traditional structures, these loads are mainly borne by the fairing support itself and its welded joints to the hub, easily leading to stress concentration, weld fatigue, and consequently, weld breakage or fracture.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] See Figure 1 and Figure 2 This application provides a support structure including a first support assembly. The first support assembly includes a first connecting plate 100, a second connecting plate 101, and a first support member 102. The first connecting plate 100 is fixedly connected to the flange 201 of the hub 200, and the second connecting plate 101 is fixedly connected to the fairing bracket 300. The first end of the first support member 102 is connected to the first connecting plate 100, and the second end of the first support member 102 is connected to the second connecting plate 101. The first support assembly is used to support the fairing bracket 300, and the fairing bracket 300 is fixed to the hub 200.

[0024] Specifically, the flange 201 of the hub 200 is usually used to connect key components such as the pitch bearing. When the wind turbine is running, the complex loads (including wind pressure, gravity, centrifugal force, vibration, etc.) acting on the fairing and fairing support 300 are now transmitted in parallel paths in addition to the original welding points. That is, part of the load is transmitted to the first connecting plate 100 through the second connecting plate 101 and the first support member 102, and finally introduced into the flange 201 of the hub 200.

[0025] The support structure provided by this utility model establishes a stable support path between the hub 200 and the fairing support 300 by connecting the first end of the first support component to the flange 201 of the hub 200 and the second end to the fairing support 300. During wind turbine operation, the fairing and its support 300 bear significant wind and vibration loads. In traditional structures, these loads are mainly borne by the fairing support 300 itself and its welded joint with the hub 200, which can easily lead to stress concentration, weld fatigue, and consequently, weld breakage or fracture. By adding the first support component, some of the load is directly transferred to the flange 201 of the hub 200, effectively dispersing the force and torque borne by the fairing support 300, reducing its structural burden, enhancing overall rigidity, and thus improving the support stability of the fairing support 300.

[0026] To optimize the above technical solution, the first connecting plate 100 includes a first connecting part 1001 and a second connecting part 1002. The first connecting part 1001 and the second connecting part 1002 have an included angle of 0 to 90 degrees. The first connecting part 1001 is bolted to the flange 201, and the second connecting part 1002 is bolted to the first end of the first support member 102.

[0027] Specifically, the first connecting part 1001 is used to achieve a reliable fit and connection with the flange 201 of the hub 200. Since the end face of the flange 201 of the hub 200 is usually flat, the first connecting part 1001 is designed to match the flat surface, which can achieve surface contact fixation by bolts to ensure a stable connection. The first connecting part 1001 and the second connecting part 1002 have an included angle of 0 to 90 degrees (the second connecting part 1002 can be a right angle L-shape with the first connecting part 1001, or other acute angles). On the one hand, it can satisfy the fit between the first connecting part 1001 and the flange 201, and on the other hand, it can avoid the installation of other components (such as pipelines and sensors) on the hub 200, thus improving the spatial adaptability of the support structure.

[0028] Because the first connecting part 1001 and the second connecting part 1002 have an included angle of 0 to 90 degrees, construction personnel can more easily align the bolt holes during on-site installation, which improves the convenience and reliability of installation and ensures the reliability and consistency of connection quality.

[0029] See Figure 3 and Figure 4To optimize the above technical solution, the fairing support 300 is provided with a fixing member 303. One end of the fixing member 303 is fixedly connected to the fairing support 300, and the other end of the fixing member 303 is provided with a fixing hole. The second connecting plate 101 includes a third connecting part 1011 and a fourth connecting part 1012. The third connecting part 1011 and the fourth connecting part 1012 have an included angle of 0 to 90 degrees. The third connecting part 1011 is bolted to the second end of the first support member 102, and the fourth connecting part 1012 is bolted to the fixing hole.

[0030] Specifically, the fairing bracket 300 is used to install the fairing and requires an "adapter ear plate" or "connecting support" with two through holes. The aforementioned fastener 303 can directly adopt the existing "adapter ear plate" or "connecting support". The through holes are the aforementioned fixing holes. The fastener 303 and the fairing bracket 300 can be a welded integral structure to improve the structural strength of the fairing bracket 300.

[0031] Specifically, the principle behind the angle between the third connecting part 1011 and the fourth connecting part 1012 is the same as that behind the angle between the first connecting part 1001 and the second connecting part 1002. Both are designed to facilitate fitting and installation and optimize the installation space, allowing the second connecting plate 101 to flexibly adjust its posture according to the position and direction of the fixing part 303 on the fairing bracket 300, ensuring that the second connecting plate 101 is in a good stress state. This will not be elaborated further here.

[0032] In use, the load from the first support member 102 first acts on the third connecting part 1011 of the second connecting plate 101, then the force is transmitted to the fourth connecting part 1012, and then transmitted to the fixing member 303 through bolt connection, and finally diffused onto the main body of the fairing bracket 300. The fixing member 303, as a reinforced part, can withstand concentrated bolt preload and working load, thereby improving the overall support capacity of the fairing bracket 300.

[0033] To optimize the above technical solution, the first support member 102 includes a first rod and a second rod. The first end of the first rod is connected to the second connecting part 1002, and the second end of the first rod includes either an outer tube or an inner tube. The first end of the second rod is connected to the third connecting part 1011, and the second end of the second rod includes either an outer tube or an inner tube. The outer tube and the inner tube cooperate with each other, and the first rod and the second rod can move relative to each other along the axial direction of the first support member 102.

[0034] Specifically, through the sleeve connection between the outer tube and the inner tube, the first rod and the second rod can slide relative to each other along the axial direction of the first support 102, thereby steplessly adjusting the total length of the entire first support 102 to compensate for the uncertain deviation in the actual distance between the hub 200 flange 201 and the predetermined reinforcement point on the fairing bracket 300.

[0035] In some embodiments, at least one (usually two at 90 degrees) threaded hole is opened on the side wall of the outer tube and equipped with a locking bolt. During adjustment, the bolt is loosened, slid to a suitable length, and then the bolt is tightened to fix the inner tube by using the end of the bolt to press against it.

[0036] In other embodiments, a series of equidistant adjustment holes are opened along the axial direction on the inner and outer tubes, and the length is selected and fixed by inserting pins or bolts.

[0037] In other embodiments, the inner and outer tubes are connected to each other by internal and external threads and their relative positions are adjusted.

[0038] The cooperation between the inner and outer tubes only needs to enable the first rod and the second rod to move relative to each other along the axial direction of the first support 102, which will not be elaborated here.

[0039] During the installation and adjustment phase, the workers fix the first connecting plate 100 to the flange 201 and the second connecting plate 101 to the guide vane bracket 300. Then, by pushing or pulling the first or second rod, the inner and outer pipes slide relative to each other until both ends of the first support 102 can easily and stress-free align with the corresponding joints on the first connecting plate 100 and the second connecting plate 101. After adjusting to the optimal length, the positions of the inner and outer pipes are locked to prevent them from sliding during operation.

[0040] This arrangement allows the same support structure to be used for different individual fans of the same model, and even for installation needs under different operating conditions (such as thermal expansion and contraction caused by temperature), which greatly improves the versatility of the support structure and the efficiency of on-site installation.

[0041] To optimize the above technical solution, the second connecting plate 101 also includes a reinforcing plate 1013. One side of the reinforcing plate 1013 is connected to the third connecting part 1011, and the other side of the reinforcing plate 1013 is connected to the fourth connecting part 1012.

[0042] Specifically, the second connecting plate 101 is used to connect the first support member 102 and the fixing member 303. The corner area between the third connecting part 1011 and the fourth connecting part 1012 of the second connecting plate 101 is a key area of ​​stress concentration. When the load direction transmitted from the first support member 102 is not completely perpendicular to the plane of the second connecting plate 101, or when there is a large bending moment, the corner of the second connecting plate 101 will be subjected to complex tensile, compressive, and bending stresses. The reinforcing plate 1013 is essentially a triangular reinforcing rib or an inclined support plate, thereby providing a direct force diversion path. That is, a part of the load will be "diverted" through the reinforcing plate 1013. The reinforcing plate 1013 "supports" the angle between the third connecting part 1011 and the fourth connecting part 1012, preventing the angle from opening or closing and ensuring the overall geometric stability and rigidity of the connection node, thereby improving the support stability of the fairing bracket 300.

[0043] To optimize the above technical solution, the first support assembly further includes a third connecting plate 103 and a second support member 104. The third connecting plate 103 is connected to the flange 201, the first end of the second support member 104 is connected to the third connecting plate 103, and the second end of the second support member 104 is connected to the third connecting part 1011.

[0044] Specifically, the third connecting plate 103 functions similarly to the first connecting plate, and is also installed on the flange 201 of the hub 200 (usually at different bolt positions on the same flange 201, or on adjacent flanges 201). The second support member 104 functions similarly to the first support member 102. The first end of the second support member 104 is connected to the third connecting plate 103, and the second end of the second support member 104 is connected to the third connecting portion 1011 of the second connecting plate 101. That is, the second support member 104 and the first support member 102 meet at the same point (the third connecting portion 1011) on the second connecting plate 101, thus forming a "triangular" or "A-shaped" stable support structure. Starting from the two independent mounting points (the first connecting plate 100 and the third connecting plate 103) on the flange 201 of the hub 200, they are supported together on the same target point (the third connecting portion 1011 of the second connecting plate 101) of the fairing bracket 300 through the first support member 102 and the second support member 104, respectively. When the fairing bracket 300 is subjected to a load, the load is distributed to the first support 102 and the second support 104 through the second connecting plate 101, and then transmitted back to the two independent mounting points on the flange 201 of the hub 200 by the first support 102 and the second support 104 respectively.

[0045] This arrangement can better resist forces and moments from different directions, effectively suppress the lateral swaying and torsional deformation of the fairing support 300, improve the support stability of the fairing support 300, and ensure that if either the first support member 102 or the second support member 104 is accidentally damaged or fails to connect, the other support member 102 or the second support member 104 can still provide a considerable degree of support, thereby greatly improving the safety redundancy and reliability of the support structure.

[0046] To optimize the above technical solution, the second support member 104 is an angle steel, and the second support member 104 is bolted to the third connecting plate 103 and the third connecting part 1011 respectively.

[0047] Specifically, angle steel is a long strip of steel with an L-shaped cross-section. It has good resistance to compression, bending, and torsion, can withstand complex loads, and can be easily drilled on its two vertical edges (flanges) for bolt connections. At the same time, angle steel is relatively easy to obtain, resulting in lower material and processing costs.

[0048] Specifically, the second support member 104 is bolted to the third connecting plate 103 and the third connecting part 1011 respectively. Combined with the bolt connection methods of the above components, the support structure can meet the characteristics of being non-welded and detachable, thereby ensuring the ease of construction and maintainability of the support structure.

[0049] Specifically, the flat flange of the angle steel provides an ideal contact surface for bolted connections and facilitates connection. The angle steel is closely connected to the third connecting plate 103 and the third connecting part 1011, which can provide a large contact area and stable shear resistance, further improving the support stability of the support structure.

[0050] To optimize the above technical solution, the fairing bracket 300 includes a first bracket 301, a second bracket 302, and a connecting frame 304. The two ends of the connecting frame 304 are respectively connected to the first bracket 301 and the second bracket 302. The first bracket 301 is connected to the interior of the hub 200, and the second bracket 302 is suspended outside the hub 200. The size of the first bracket 301 is smaller than the size of the second bracket 302. The second end of the first support assembly is connected to the second bracket 302. The system also includes a second support assembly. The first end of the second support assembly is connected to the second end of the first support assembly, and the second end of the second support assembly is connected to the first bracket 301.

[0051] Specifically, both the first bracket 301 and the second bracket 302 are annular brackets, and the two ends of the connecting frame 304 are respectively connected to the circumference of the first bracket 301 and the second bracket 302. In the prior art, the first bracket 301 and the second bracket 302 are supported by the connecting frame 304, and there are no supporting components between the first bracket 301, the second bracket 302 and the flange 201.

[0052] Specifically, the first support component acts as the "main support" and directly supports the second bracket 302 from the flange 201 of the hub 200. The second support component acts as the "secondary support" and pulls the second bracket 302, which has been supported by the main support, at one end, while the other end is fixed to the first bracket 301, which is closer to the root and relatively more stable inside the hub 200.

[0053] The second support component constrains the deformation of the second bracket 302 relative to the first bracket 301. When the second bracket 302 is subjected to downward deflection or torsion, the second support component pulls it back, working synergistically with the first support component to limit the bending and torsional deformation of the fairing bracket 300, thereby improving the support stability of the support structure.

[0054] See Figure 5 To optimize the above technical solution, the second support component includes a first bonding plate 401, a second bonding plate 402, and a third support member 400. The two ends of the third support member 400 are respectively connected to the first bonding plate 401 and the second bonding plate 402. The first bonding plate 401 is bonded to the first bracket 301 and fixedly connected to the first bracket 301. The second bonding plate 402 is bonded to the first support component and bolted to the first support component.

[0055] Specifically, the first bonding plate 401 is designed to connect with the first bracket 301. The first bonding plate 401 is designed to match the outer surface shape of the first bracket 301, and is fixedly connected through large-area surface contact (such as welding, bolting, or being tubularly fitted onto the outside of the first bracket 301) to ensure the stability of the connection. The second bonding plate 402 is designed to connect with the first support assembly (specifically, the second end of the first support assembly, such as the second connecting plate 101), also using a bonding method to ensure the rigidity and reliability of the connection. The third support member 400 is a connecting rod linking the first bonding plate 401 and the second bonding plate 402, and can be a rod, tube, or other component.

[0056] In use, the two ends of the third support member 400 are firmly connected to the first bonding plate 401 and the second bonding plate 402, respectively. The first bonding plate 401 is tightly bonded and fixed to the first bracket 301, and the second bonding plate 402 is tightly bonded and fixed to the second connecting plate 101 of the first support assembly. A rigid indirect connection channel is established between the first bracket 301 and the first support assembly. When the first support assembly drives the second bracket 302 to move, the movement trend is transmitted to the first bracket 301 through the second bonding plate 402, the third support member 400, and the first bonding plate 401, and vice versa. The first support assembly and the second support assembly mutually constrain each other to achieve the purpose of jointly stabilizing the fairing bracket 300.

[0057] This application embodiment also provides a wheel hub 200, including a wheel hub body, a fairing bracket 300, and a support structure as described above. The wheel hub body is connected to multiple flanges 201. One side of the fairing bracket 300 is connected to the interior of the wheel hub body, and the other side of the fairing bracket 300 is connected to the support structure. Multiple support structures can be evenly arranged along the circumference of the fairing bracket 300 to ensure uniform stress distribution on the fairing bracket 300 and improve its support stability.

[0058] The specific structure of the support structure is as described in the above embodiments. Since this wheel hub 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.
