Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a support component for a wind power generation device and a wind power generation device. Background Technology

[0002] In the structural design of wind power generation, the wind turbine, as one of the core components, undertakes the crucial task of capturing wind energy and converting it into mechanical energy. A reliable connection between the wind turbine and the support rod is fundamental to ensuring the stable and efficient operation of the entire wind energy conversion system. Typically, the wind turbine is securely assembled to the support rod via a flange.

[0003] However, in practical applications, differences in the diameter, number of blades, blade length, and materials of different wind turbine models result in varying mechanical properties such as wind load and moment of inertia. Simultaneously, the support rods also exhibit diverse specifications and dimensions due to design requirements, operating environment, and load-bearing capacity. This diversity in wind turbine and support rod models directly leads to differences in the dimensions, bolt hole layout, and load-bearing capacity of the flanges required for their connection.

[0004] The incompatibility between different models of wind turbines and support rods makes it impossible to establish a unified standard for the matching flanges, resulting in a lack of versatility. This not only increases the variety of parts and management costs during equipment manufacturing but also creates inconvenience for on-site installation, maintenance, and replacement, impacting the economic viability and maintainability of wind power generation systems. Utility Model Content

[0005] In view of this, the present invention provides a support component and a wind power generation device for wind power generation devices, so as to solve the problem that different models of wind turbines and support rods require different flange sizes and lack universality.

[0006] In a first aspect, this utility model provides a support assembly for a wind power generation device, including a support rod, a housing, an adjusting part, and a fixing part; the support rod has a connecting section at its top; the housing is slidably fitted onto the outer periphery of the connecting section along the axial direction of the support rod; the housing is used to connect a power generation unit; the adjusting part is detachably filled in the radial gap between the housing and the connecting section; the fixing part is located below the adjusting part along the axial direction of the support rod and is fixed to the support rod; wherein, the housing has a fixed position connected to the fixing part and a separated position separated from the fixing part; when the housing is in the fixed position, along the radial direction of the support rod, the two side surfaces of the adjusting part abut against the outer surface of the connecting section and the inner wall of the housing, respectively.

[0007] Beneficial effects: By incorporating a detachable adjustment section, the filling position and thickness of the adjustment section within the radial gap can be flexibly adjusted, allowing the same housing to accommodate support rods of different diameters, or the same support rod to accommodate housings of different sizes. When the required support rod or housing specifications change, only the adjustment section needs to be replaced or moved to match the new radial gap size, eliminating the need for customized housings or connecting structures, thus improving the universal assembly capability for support rods and housings of different specifications. Furthermore, filling the radial gap between the housing and the support rod connection section with the detachable adjustment section effectively eliminates the gap between them. When the housing is in a fixed position, the two sides of the adjustment section tightly abut against the outer surface of the connection section and the inner wall of the housing, respectively, enhancing the radial rigidity and stability of the housing, effectively preventing shaking or displacement, and ensuring precise positioning. Because the enclosure has a fixed position for connecting to the fixed part and a separate position for separating from the fixed part, the enclosure can be raised to the separate position during installation or maintenance to facilitate the insertion or removal of the adjustment part; after adjustment, the enclosure can be lowered to the fixed position and locked to the fixed part, simplifying the installation, debugging and disassembly process of the support components.

[0008] In one optional embodiment, a first fastener is further included; a first through hole is provided on the fixing part along the axial direction of the support rod, and a first threaded hole is provided on the bottom of the housing; the first fastener passes through the first through hole and is threadedly connected to the first threaded hole.

[0009] Beneficial effects: By setting the first fastener to pass through the first through hole of the fixing part and tighten it with the first threaded hole at the bottom of the housing, the housing can be firmly locked to the fixing part axially. This threaded connection process simultaneously applies a downward pulling force, causing the housing to move downwards until the two sides of the adjusting part along the radial direction of the support rod are tightly abutted against the outer surface of the connecting section and the inner wall of the housing, respectively. This not only provides reliable axial restraint through the threaded connection, effectively preventing the housing from accidentally sliding or loosening on the support rod, thus ensuring the stability and reliability of the power generation unit carried on it; but also makes the connection and separation between the housing and the fixing part extremely simple. Fixing or separation can be completed simply by tightening or loosening the first fastener, without the need for complex tools or additional structures, improving installation, commissioning, and maintenance efficiency.

[0010] In one alternative embodiment, a second fastener is further included; along the radial direction of the support rod, the housing is provided with a second through hole, and the adjusting part is provided with a second threaded hole, the second fastener passing through the second through hole and threadedly connected to the second threaded hole.

[0011] Beneficial effects: By passing the second fastener through the second through hole of the housing and screwing it into the second threaded hole of the adjustment part, a locking force can be applied in the radial direction, thereby locking and fixing the housing in the radial direction and making the housing and the adjustment part fit tightly together, improving the rigidity and deformation resistance of the housing in the radial direction, and preventing the power generation unit from shifting due to vibration or external force.

[0012] In one optional embodiment, the connecting section is provided with a radially recessed mounting groove, and the first section of the adjusting part is fixed in the mounting groove along the radial direction of the support rod; the second section of the adjusting part protrudes from the mounting groove and abuts against the housing.

[0013] Beneficial effects: By setting a mounting groove and fixing the first section of the adjustment part within the mounting groove, the adjustment part is positioned and constrained, preventing displacement or detachment during operation and ensuring the stability of the initial installation. The second section protruding from the mounting groove is used to fill the radial gap between the housing and the support rod. The mounting groove facilitates individual replacement of the adjustment part as needed, protecting the main structure of the support rod from repeated assembly and disassembly, and improving the overall maintainability and service life of the support assembly.

[0014] In one alternative embodiment, the outer periphery of the connecting section is covered with a reinforcing layer, and along the radial direction of the support rod, both sides of the adjusting part abut against the outer surface of the reinforcing layer and the inner wall of the housing, respectively.

[0015] Beneficial effects: By wrapping the outer periphery of the connecting section with a reinforcing layer, the structural strength of the connecting section is enhanced, providing a high-strength, wear-resistant support interface for the adjustment part. By setting the reinforcing layer to directly bear the radial clamping force and friction force of the adjustment part, direct contact between the adjustment part and the connecting section body is effectively isolated, avoiding wear or deformation of the core support rod surface and extending the life of the support rod. Furthermore, when the contact surface between the reinforcing layer and the adjustment part is worn due to long-term use, only the reinforcing layer itself needs to be replaced, rather than the entire support rod, reducing maintenance costs and improving the sustainability of the support components.

[0016] In one alternative embodiment, the side wall of the enclosure is provided with an observation port.

[0017] Beneficial effects: By setting an observation port on the housing, the wear, misalignment or loosening of the adjustment part can be directly monitored. The life of the component can be assessed without disassembling the housing, preventing the risk of failure due to adjustment failure. Furthermore, when replacing the adjustment part with a different thickness to fit the new diameter support rod, the contact status between the adjustment part and the connecting section and the housing can be confirmed in real time through the observation port, ensuring the reliability of the radial locking force.

[0018] In one alternative embodiment, the housing is further provided with a protective plate, which covers the observation port.

[0019] Beneficial effects: By setting up protective plates, rainwater, sand and dust can be prevented from entering the interior of the enclosure, preventing the adjustment part from failing to lock due to corrosion or contamination, and improving the durability of the support components in harsh environments.

[0020] In one alternative embodiment, the support rod is a cement rod.

[0021] Beneficial effects: Using cement poles as support towers for wind power generation devices offers high structural strength and stability, enabling them to withstand the enormous loads generated during operation and the complex and ever-changing forces of the natural environment. This provides a reliable support foundation for the entire wind power generation system, ensuring its safety and stability during long-term operation and reducing the risk of damage or even safety accidents caused by support structure failure. Furthermore, cement poles possess excellent durability and corrosion resistance. Their material properties allow them to resist erosion from harsh environmental factors such as rain, humidity, and salt spray, reducing the need for frequent maintenance and replacement, thereby lowering maintenance and operating costs throughout the entire lifecycle.

[0022] Secondly, the present invention also provides a wind power generation device, including the aforementioned support assembly and power generation unit for the wind power generation device; the power generation unit is disposed on top of the support assembly for the wind power generation device.

[0023] In one optional embodiment, the power generation unit includes a mounting box, a power generation component, and a wind turbine component. The mounting box is fixed to the top of the support component for the wind power generation device and has an internal installation space. The power generation component is disposed within the installation space. The wind turbine component is disposed on the top of the mounting box and is drively connected to the power generation component.

[0024] Beneficial effects: By setting up an installation box and placing the power generation components inside the box, not only is the appearance of the wind power generation device improved, but the power generation components are also protected from rain, snow and lightning, and maintenance is simple and convenient.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, a support assembly for a wind power generation device is provided, including a support rod 11, a housing 12, an adjusting part 13, and a fixing part 14; the support rod 11 has a connecting section 111 at its top; the housing 12 is slidably fitted onto the outer periphery of the connecting section 111 along the axial direction of the support rod 11; the housing 12 is used to connect a power generation unit; the adjusting part 13 is detachably filled in the radial gap between the housing 12 and the connecting section 111; the fixing part 14 is located below the adjusting part 13 along the axial direction of the support rod 11 and is fixed to the support rod 11; wherein, the housing 12 has a fixed position connected to the fixing part 14 and a separated position separated from the fixing part 14; when the housing 12 is in the fixed position, along the radial direction of the support rod 11, the two side surfaces of the adjusting part 13 abut against the outer surface of the connecting section 111 and the inner wall of the housing 12, respectively.

[0035] In the above embodiments, by providing a detachable adjustment part 13, the filling position and thickness of the adjustment part 13 within the radial gap can be flexibly adjusted, allowing the same housing 12 to accommodate support rods 11 of different diameters, or the same support rod 11 to accommodate housings 12 of different sizes. When the required specifications of the support rod 11 or housing 12 change, only the adjustment part 13 needs to be replaced or moved to match the new radial gap size, without the need for customized housing 12 or connecting structures, thus improving the universal assembly capability for support rods 11 and housings 12 of different specifications. Furthermore, by filling the radial gap between the housing 12 and the connecting section 111 of the support rod 11, the detachable adjustment part 13 effectively eliminates the gap between them. When the housing 12 is in a fixed position, the two side surfaces of the adjustment part 13 tightly abut against the outer surface of the connecting section 111 and the inner wall of the housing 12, respectively, enhancing the radial rigidity and stability of the housing 12, effectively preventing shaking or displacement, and ensuring precise positioning. Since the housing 12 has a fixed position connected to the fixing part 14 and a separate position separated from the fixing part 14, the housing 12 can be lifted to the separate position during installation or maintenance to facilitate the insertion or removal of the adjustment part 13; after adjustment, the housing 12 is lowered to the fixed position and connected and locked to the fixing part 14, which simplifies the installation, debugging and disassembly process of the support components.

[0036] Preferably, when the housing 12 is in a fixed position, along the radial direction of the support rod 11, the two side surfaces of the adjustment part 13 abut against the outer surface of the connecting section 111 and the inner wall of the housing 12, respectively, and structural adhesive is applied between the abutting surfaces of the adjustment part 13 and the inner wall of the housing 12 to further enhance the stability of the connection.

[0037] In a specific embodiment, multiple adjustment parts 13 are provided, and the multiple adjustment parts 13 are evenly distributed along the circumference of the support rod 11 to ensure that the radial locking force on the housing 12 is evenly distributed, thereby improving the stability of the overall structure. Specifically, there may be two, three, or four adjustment parts 13. Preferably, in this embodiment, there are four adjustment parts 13.

[0038] Specifically, the fixing part 14 is a flange.

[0039] In a specific embodiment, the box body 12 is cone-shaped, and the inner diameter of the box body 12 gradually increases towards the side closer to the fixing part 14 along the axial direction of the support rod 11; and the adjusting part 13 is preferably a wedge-shaped block. When the box body 12 is in the fixed position, the two side surfaces of the wedge-shaped block abut against the outer surface of the connecting section 111 and the inner wall of the box body 12 respectively along the radial direction of the support rod 11.

[0040] In one embodiment, a first fastener is also included; along the axial direction of the support rod 11, the fixing part 14 is provided with a first through hole, and the bottom of the housing 12 is provided with a first threaded hole; the first fastener passes through the first through hole and is threadedly connected to the first threaded hole.

[0041] In the above embodiment, by setting a first fastener to pass through the first through hole of the fixing part 14 and tighten it with the first threaded hole at the bottom of the housing 12, the housing 12 can be firmly locked onto the fixing part 14 in the axial direction. This threaded connection process simultaneously applies a downward pulling force, causing the housing 12 to move downwards until the two sides of the adjusting part 13 along the radial direction of the support rod 11 are in close contact with the outer surface of the connecting section 111 and the inner wall of the housing 12, respectively. This not only provides reliable axial restraint through the threaded connection, effectively preventing the housing 12 from accidentally sliding or loosening on the support rod 11, thus ensuring the stability and reliability of the power generation unit carried on it; but also makes the connection and separation operations between the housing 12 and the fixing part 14 extremely simple, requiring only tightening or loosening the first fastener to complete the fixing or separation, without the need for complex tools or additional structures, thus improving installation, commissioning, and maintenance efficiency.

[0042] Preferably, the diameter of the first through hole is larger than the diameter of the first fastener rod, allowing for a slight amount of movement in the housing 12 before final tightening. This facilitates precise adjustment of the housing 12's position during installation, ensuring better alignment with the fixing part 14 or other related components, thus guaranteeing assembly accuracy. Final rigid fixation is then achieved by tightening the first fastener.

[0043] Specifically, the first through hole is a through hole with a diameter of 21 mm; the first fastener is a bolt with a nominal diameter of 20 mm.

[0044] In a specific implementation, multiple first fasteners are provided, and the multiple first fasteners are evenly spaced along the circumference of the housing 12. Each first fastener is provided with a first through hole and a first threaded hole. Specifically, there may be two, three, or four first fasteners. Preferably, in this embodiment, there are four first fasteners.

[0045] In one embodiment, a second fastener is also included; along the radial direction of the support rod 11, the housing 12 is provided with a second through hole, and the adjusting part 13 is provided with a second threaded hole, the second fastener passing through the second through hole and threadedly connected to the second threaded hole.

[0046] In the above embodiment, by passing the second fastener through the second through hole of the housing 12 and screwing it into the second threaded hole of the adjustment part 13, a locking force can be applied in the radial direction to achieve the locking and fixing of the housing 12 in the radial direction, and to make the housing 12 and the adjustment part 13 fit tightly together, thereby improving the rigidity and deformation resistance of the housing 12 in the radial direction and preventing the power generation unit from shifting due to vibration or external force.

[0047] In a specific embodiment, the adjusting part 13 is provided with a plurality of second threaded holes, which are arranged sequentially at intervals along the axial direction of the support rod 11, and each second threaded hole is provided with a second through hole and a second fastener. Specifically, each adjusting part 13 may have one, two, three or four second threaded holes. Preferably, in this embodiment, each adjusting part 13 is provided with three second threaded holes.

[0048] Preferably, the diameter of the second through hole is larger than the diameter of the second fastener, allowing for minor positional adjustments of the housing 12 relative to the adjusting part 13 before tightening. This facilitates precise alignment during installation and optimizes assembly accuracy. Once the position is determined, a secure and reliable radial fixation can be achieved simply by tightening the second fastener, making the operation simple and efficient.

[0049] In another embodiment, the second through hole can be an elongated hole extending along the axial direction of the support rod 11 and corresponding to the positions of multiple second threaded holes. Specifically, multiple second fasteners pass through the elongated hole and connect to the corresponding second threaded holes. The heads of the second fasteners are spaced apart from the housing 12. During the connection of the first fastener to the housing 12, the housing 12 will slide axially, and the second fastener will slide relative to the housing 12 within the elongated hole. After the first fastener is in place, the second fastener is tightened until its head presses against the housing 12. It should be noted that the diameter of the second fastener head is larger than the width of the elongated hole, ensuring that the second fastener can effectively connect the housing 12 and the adjusting part 13.

[0050] In one embodiment, the connecting section 111 is provided with a radially recessed mounting groove 112, and the first section of the adjusting part 13 is fixed in the mounting groove 112 along the radial direction of the support rod 11; the second section of the adjusting part 13 protrudes from the mounting groove 112 and abuts against the housing 12.

[0051] In the above embodiment, by providing the mounting groove 112 and fixing the first section of the adjusting part 13 within the mounting groove 112, the adjusting part 13 is positioned and constrained, preventing it from shifting or falling off during operation and ensuring the stability of the initial installation. The second section protruding from the mounting groove 112 is used to fill the radial gap between the housing 12 and the support rod 11. The mounting groove 112 facilitates the individual replacement of the adjusting part 13 as needed, protecting the main structure of the support rod 11 from repeated assembly and disassembly, and improving the overall maintainability and service life of the support assembly.

[0052] In a specific embodiment, multiple mounting slots 112 are provided, and each mounting slot 112 is correspondingly provided with an adjustment part 13.

[0053] In a specific embodiment, the adjustment part 13 is fixed in the mounting groove 112 by snap-fit ​​or by fasteners such as bolts.

[0054] In a specific embodiment, the fixing part 14 is fitted under the mounting groove 112 on the support rod 11; the adjusting part 13 is positioned and fixed in the mounting groove 112; then the housing 12 is installed, so that the first fastener passes through its first through hole and is screwed into the first threaded hole of the housing 12. When the first fastener is tightened, the housing 12 is pulled downward and moves axially until the inner wall of the housing 12 is in close contact with the surface of the adjusting part 13. Then the second fastener is tightened to complete the assembly of the entire support assembly.

[0055] In one embodiment, the outer periphery of the connecting section 111 is covered with a reinforcing layer 113, and along the radial direction of the support rod 11, the two sides of the adjusting part 13 abut against the outer surface of the reinforcing layer 113 and the inner wall of the box 12, respectively.

[0056] In the above embodiments, by covering the outer periphery of the connecting section 111 with a reinforcing layer 113, the structural strength of the connecting section 111 is enhanced, providing a high-strength, wear-resistant support interface for the adjusting part 13. By setting the reinforcing layer 113 to directly bear the radial clamping force and friction force of the adjusting part 13, the direct contact between the adjusting part 13 and the body of the connecting section 111 is effectively isolated, avoiding wear or deformation of the surface of the core support rod 11 and extending the life of the support rod 11. Furthermore, when the contact surface between the reinforcing layer 113 and the adjusting part 13 is worn due to long-term use, only the reinforcing layer 113 itself needs to be replaced, without replacing the entire support rod 11, reducing maintenance costs and improving the sustainability of the support assembly.

[0057] In a specific implementation, the reinforcing layer 113 may be a single carbon fiber or glass fiber layer.

[0058] In one embodiment, the side wall of the housing 12 is provided with an observation port 121.

[0059] In the above embodiment, by providing an observation port 121 on the housing 12, the wear, misalignment or loosening of the adjustment part 13 can be directly monitored. The life of the component can be assessed without disassembling the housing 12, preventing the risk of failure due to adjustment failure. Furthermore, when replacing the adjustment part 13 with one of different thicknesses to fit the support rod 11 of a new diameter, the contact state between the adjustment part 13 and the connecting section 111 and the housing 12 can be confirmed in real time through the observation port 121, ensuring the reliability of the radial locking force.

[0060] In a specific implementation, an observation port 121 is provided between each pair of adjacent adjustment parts 13, which helps to achieve all-round monitoring of the status of multiple adjustment parts 13 inside the box.

[0061] Specifically, the observation port 121 is rectangular.

[0062] In one embodiment, the housing 12 is further provided with a protective plate 122, which covers the observation port 121.

[0063] In the above embodiment, by setting the protective plate 122, rainwater, sand and dust can be blocked from entering the interior of the box 12, preventing the adjustment part 13 from failing to lock due to corrosion or pollution, and improving the durability of the support component in harsh environments.

[0064] In one embodiment of this invention, the protective plate 122 is a louvered type. In another embodiment, the protective plate 122 is a plate-like structure with a hinged or snap-fit ​​design, which ensures both protective efficiency and ease of maintenance. The protective plate 122 also has ventilation holes, providing ventilation and cooling while protecting the components installed inside the enclosure 12. In yet another embodiment, the protective plate 122 is preferably made of impact-resistant and transparent material such as polycarbonate. Even when closed, the status of the adjustment section 13 can be monitored in real time, eliminating the maintenance burden of repeated disassembly and reassembly required by traditional metal covers and reducing the risk of misoperation.

[0065] In one embodiment, the support rod 11 is a cement rod.

[0066] In the above embodiments, using cement poles as the support towers for the power generation device provides high structural strength and stability. These poles can withstand the enormous loads generated during the operation of the power generation unit, as well as the complex and ever-changing forces of the natural environment. This provides a reliable support foundation for the entire wind power generation device, ensuring its safety and stability during long-term operation and reducing the risk of damage or even safety accidents caused by support structure failure. Furthermore, cement poles possess excellent durability and corrosion resistance. Their material properties allow them to resist erosion from harsh environmental factors such as rainwater, humidity, and salt spray, making them less prone to rust and rot. This reduces the need for frequent maintenance and replacement, thereby lowering maintenance and operating costs throughout the entire lifecycle.

[0067] In specific implementations, the support rod 11 includes, but is not limited to, cement rods, metal rods, etc.

[0068] Preferably, the support rod 11 is an ultra-high performance concrete (UHPC) cement rod. Compared with ordinary concrete cement rods, its compressive strength reaches 100MPa-200MPa, tensile strength is greater than or equal to 3.5MPa, and bending strength is greater than or equal to 22MPa. Through steel fiber or hybrid fiber toughening, its impact resistance and fatigue resistance are enhanced. Compared with traditional concrete cement rods, the wall thickness is reduced by 50%, and the weight is reduced by 40% to 50%. Furthermore, while ensuring the same strength, its cost is lower than that of metal rods.

[0069] According to an embodiment of the present invention, another aspect provides a wind power generation device, including the aforementioned support assembly and power generation unit for the wind power generation device; the power generation unit is disposed on top of the support assembly for the wind power generation device.

[0070] In this embodiment, the wind power generation device is a vertical axis wind power generation device.

[0071] In one embodiment, the power generation unit includes a mounting box 21, a power generation component 22, and a wind turbine component 23. The mounting box 21 is fixed to the top of the support component for the wind power generation device and has an installation space inside. The power generation component 22 is disposed in the installation space. The wind turbine component 23 is disposed on the top of the mounting box 21 and is connected to the power generation component 22 in a transmission manner.

[0072] In the above embodiments, by setting up the mounting box 21 and placing the power generation component 22 inside the mounting box 21, not only is the appearance of the wind power generation device improved, but the power generation component 22 can also be protected from rain, snow and lightning, and maintenance is simple and convenient.

[0073] Specifically, the mounting box 21 is cylindrical.

[0074] Specifically, the power generation assembly 22 may include components such as a generator, a speed increaser, and a coupling. The wind turbine assembly 23 may include components such as a main shaft and an impeller.

[0075] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
