Description

Technical Field

[0001] The present application relates to the technical field of wind power equipment, and in particular to a support structure and a wind power tower assembly. Background Art

[0002] With the change of my country's energy structure, the wind power industry has achieved rapid development. Wind turbine towers are an important component of wind power generation systems, used to support the nacelle and blades of wind turbines.

[0003] To facilitate transportation and installation, traditional wind turbine towers typically utilize a multi-segment structure, with flanges welded to each end to connect the segments. To prevent the flanges from deforming, channel steel is typically used to support them. Specifically, holes are drilled at each end of the channel steel, which is then bolted to the flange holes and installed at the end of the flange.

[0004] However, as wind turbines develop towards larger sizes, the height and diameter of wind turbine towers are also increasing. Traditional channel steels can no longer meet the requirements of flange deformation control. The method of installing channel steels only on the flange end face is prone to deformation control position deviation, causing the weld between the flange and the cylinder section to tear.

[0005] Therefore, there is an urgent need for a support structure to meet the support requirements of large-diameter wind turbine towers. Summary of the Invention

[0006] The embodiments of the present application provide a support structure and a wind turbine tower assembly. The support structure can provide support at any position inside the end of the wind turbine tower, thereby avoiding deformation of the end of the wind turbine tower.

[0007] In a first aspect, an embodiment of the present application provides a support structure for a wind turbine tower, the support structure comprising:

[0008] The support body is configured to be disposed in a communication cavity of a communication member of the wind turbine tower and / or in a cylinder segment; the cavity wall of the communication cavity and the inner wall of the cylinder segment form a circumferential inner wall of the wind turbine tower; the support body has a first end and a second end in the longitudinal direction;

[0010] When the support body is arranged in the communication cavity of the connecting piece and / or the cylinder section of the wind turbine tower, the first flexible support piece and the second flexible support piece are both supported on the circumferential inner wall of the wind turbine tower.

[0011] The support structure provided in the present application is provided with a support body and a flexible support component. In the length direction of the support body, the first end of the support body is connected to the first flexible support member, and the second end of the support body is connected to the second flexible support member.

[0012] When the support body is arranged inside the end of the wind turbine tower, the first flexible support member and the second flexible support member are supported on the circumferential inner wall of the wind turbine tower. The different diameters of the wind turbine towers result in different locations of stress concentration during transportation. Therefore, the locations of the wind turbine tower that require deformation control are also different. Unlike traditional support structures that can only act on the end of the wind turbine tower, the support structure provided by the present application moves the action position of the support structure to the inside of the flange. According to the different diameters of the wind turbine tower and the flange, the support structure is supported at the corresponding deformation control position. The action position is free, which can avoid the tearing of the welds between the flange and the wind turbine tower due to the deviation of the deformation control position, and meet the transportation support requirements of large-diameter wind turbine towers.

[0013] Moreover, through the flexible support assembly, the support structure can be supported on the circumferential inner wall of the wind turbine tower without bolts, and the support body is in flexible contact with the circumferential inner wall of the wind turbine tower, thereby avoiding the problem of mechanical damage to the flange hole caused by the rigid contact between the support body and the circumferential inner wall of the wind turbine tower, further reducing the risk of additional mechanical damage.

[0014] In some possible implementations of the present application, the first flexible support member covers the end surface of the support body at the first end and is connected to the first end.

[0015] In some possible implementations of the present application, the support body has a first connecting plate on an end surface of the first end;

[0016] The first flexible support member is arranged on the plate surface of the first connecting plate and is detachably connected to the first connecting plate.

[0017] In some possible implementations of the present application, the surface area of ​​the first connecting plate is greater than or equal to the end surface area of ​​the first end; and the first flexible support member covers the surface area of ​​the first connecting plate.

[0018] In some possible implementations of the present application, the second flexible support member covers the end surface of the support body at the second end and is connected to the second end.

[0019] In some possible implementations of the present application, the support body has a second connecting plate on an end surface of the second end;

[0020] The second flexible support member is arranged on the plate surface of the second connecting plate and is detachably connected to the second connecting plate.

[0021] In some possible implementations of the present application, the surface area of ​​the second connecting plate is greater than or equal to the end surface area of ​​the second end; and the second flexible support member covers the surface area of ​​the second connecting plate.

[0022] In some possible implementations of the present application, the support body includes a first support segment and a second support segment, the second support segment includes a fixed segment and a telescopic segment, the fixed segment is connected to the first support segment; an end of the first support segment facing away from the fixed segment forms the first end;

[0023] The telescopic section is connected to a side of the fixed section away from the first supporting section, and the telescopic section can be extended or retracted relative to the fixed section; one end of the telescopic section away from the fixed section forms the second end.

[0024] In some possible implementations of the present application, the support body further includes a third connecting plate, wherein the third connecting plate is disposed between the first supporting segment and the fixing segment, and the first supporting segment and the fixing segment are detachably connected.

[0025] On the other hand, the present application also provides a wind turbine tower assembly, comprising:

[0026] A wind turbine tower comprises a cylinder segment and a connecting piece, wherein the connecting piece is provided at the end of the cylinder segment and has a connecting cavity; the cavity wall of the connecting cavity and the inner wall of the cylinder segment form the circumferential inner wall of the wind turbine tower;

[0027] The support structure as described in any one of the above items is arranged in the cylinder section and / or the connecting cavity, and the support structure has a first flexible support member and a second flexible support member, and the first flexible support member and the second flexible support member are both supported on the circumferential inner wall of the wind turbine tower.

[0028] The wind turbine tower assembly provided in this application adopts the support structure provided in this application, and therefore has the same technical effect, namely, meeting the transportation support requirements of large-diameter wind turbine towers and reducing the mechanical damage caused by the rigid contact between the support body and the circumferential inner wall of the wind turbine tower.

[0041] The wind power industry is a recyclable new energy industry. Wind turbine towers are an important component of wind power systems, used to support the nacelle and blades of wind turbines.

[0042] Traditional wind turbine towers typically utilize a multi-segment structure for ease of transportation and installation. To ensure the tower's strength and stability, flanges are welded to each end of the segments, connecting adjacent segments via flanges. In recent years, with China's vigorous development of the wind power industry, the installed capacity of simple wind turbine towers has increased rapidly, and the diameter of wind turbine towers has also increased rapidly along with this increase in installed capacity. Due to their large diameter, the flanges can experience varying degrees of structural deformation due to bumps during transportation.

[0043] During transportation, the traditional method for preventing flange deformation is to drill holes at both ends of the channel steel and bolt the channel steel to the flange ends. Specifically, the channel steel can form a cross bracket or a Pozi bracket at the flange end to prevent deformation. However, this type of deformation prevention measure is only suitable for wind turbine towers with smaller diameters. For wind turbine towers with larger diameters, it is easy to cause the weld between the flange and the wind turbine tower to tear.

[0044] In addition, the traditional flange deformation prevention measure is to connect the flange and channel steel with bolts, relying on the rigid contact between the bolts and the flange hole to control deformation. The main force comes from the shear stress of the bolts, which can easily cause mechanical damage to the flange hole during transportation.

[0045] Therefore, how to meet the support requirements of towers with excessively large diameters and avoid tearing of the welds between the flange and the wind turbine tower and mechanical damage to the flange holes is a technical problem that urgently needs to be solved.

[0046] In light of this, embodiments of the present application provide a support structure for use in wind turbine towers. This support structure is located within the end of the wind turbine tower. Based on the varying diameters of the wind turbine tower, appropriate support locations are selected within the end of the wind turbine tower to avoid deviations in the deformation control position, thereby preventing tearing of the wind turbine tower end. The deformation control position refers to an area of ​​the tower end that requires special attention and is prone to deformation, as it is susceptible to stress concentration and deformation.

[0047] A first flexible support member and a second flexible support member are provided at both ends of the support body of the support structure. The first flexible support member and the second flexible support member are in contact with the circumferential inner wall of the end of the wind turbine tower, so that the support structure can be supported inside the end of the wind turbine tower without bolts, so that the support body is in flexible contact with the circumferential inner wall of the wind turbine tower, thereby avoiding the problem of mechanical damage to the flange hole caused by the rigid contact between the support body and the circumferential inner wall of the wind turbine tower, and further reducing the risk of additional mechanical damage.

[0048] The support structure provided in the embodiments of the present application is further described below with reference to the accompanying drawings and embodiments.

[0049] refer to Figure 1 and Figure 2 The embodiment of the present application provides a support structure, which includes a support body 100 and a flexible support assembly 200. The support body 100 is arranged in a communication cavity of a connecting piece of a wind turbine tower and / or in a cylinder section.

[0050] The support body 100 has a first end 111 and a second end 121 in the longitudinal direction. The flexible support assembly 200 includes a first flexible support member 210 and a second flexible support member 220. The first flexible support member 210 is mounted on the first end 111 of the support body 100, and the second flexible support member 220 is mounted on the second end 121 of the support body 100.

[0051] Among them, the cavity wall of the connecting cavity and the inner wall of the cylinder section form the circumferential inner wall of the wind turbine tower. When the support body 100 is arranged in the connecting cavity and / or the cylinder section of the connecting part of the wind turbine tower, the first flexible support member 210 and the second flexible support member 220 both support the circumferential inner wall of the wind turbine tower.

[0052] For example, the connecting member of a wind turbine tower can be a flange. The wind turbine tower comprises at least two segments, each of which has a flange at its end. For example, the flange can be welded to the end of the segment. The flange is used to connect the segments. The flange wall and the inner wall of the segment form the circumferential inner wall of the wind turbine tower.

[0053] Due to the different diameters of wind turbine towers, the deformation control positions are different. The support body 100 can be arranged inside the flange according to the support requirements.

[0054] For example, a supporting body 100 may be provided inside the flange to support the flange at a deformation control position.

[0055] like Figure 3 As shown, multiple support bodies 100 can also be installed inside the flange. These support bodies 100 are arranged in a cross pattern, with the intersection coinciding with the central axis of the flange. The support bodies 100 are located in the same plane, which is perpendicular to the central axis of the flange. For example, two support bodies 100 can be installed inside the flange in a cross configuration, or three support bodies 100 can be installed inside the flange in a "P-shaped" configuration.

[0056] A plurality of support bodies 100 may also be arranged in sequence in the extension direction of the central axis of the flange to support multiple positions inside the flange.

[0057] In addition, the support body 100 can also be arranged inside the cylinder section of the wind turbine tower to further support the wind turbine tower.

[0058] Furthermore, the supporting body 100 can also be simultaneously disposed inside the flange and the cylinder section of the wind turbine tower to further support the wind turbine tower.

[0059] In the embodiment of the present application, the number of the supporting bodies 100 is not limited, as long as they can support the deformation control position.

[0060] The embodiment of the present application moves the action position of the support structure to the inside of the flange. According to the different diameters of the wind turbine tower and the flange, the support structure is supported at the corresponding deformation control position. The action position is free, which can avoid the tearing of the welds between the flange and the wind turbine tower due to deviation in the deformation control position, and meet the transportation support requirements of large-diameter wind turbine towers.

[0061] The support structure does not require bolts to connect to the flange, thus avoiding mechanical damage to the flange hole caused by the shear stress of the bolts due to the rigid connection between the bolts and the flange hole. A first flexible support member 210 and a second flexible support member 220 are provided at both ends of the support body 100. During transportation, the first and second flexible supports 210, 220 contact the circumferential inner wall of the flange, acting as a shock absorber, avoiding rigid contact between the support body 100 and the interior of the flange, and reducing the possibility of mechanical damage.

[0062] In some embodiments of the present application, the first flexible support member 210 may only cover the end surface of the support body 100 at the first end 111 and be connected to the first end 111. The first flexible support member 210 may also have a receiving groove, and the first end 111 of the support body 100 is installed in the receiving groove, and the first flexible support member 210 covers the end surface and part of the side wall of the first end 111 of the support body 100.

[0063] Similarly, the connection method between the second flexible support member 220 and the second end 121 of the support body 100 is the same as the connection method between the first flexible support member 210 and the first end 111 of the support body 100 .

[0064] Exemplarily, the first flexible support member 210 and the second flexible support member 220 are rubber pads, which have good elasticity and shock absorption properties, can effectively buffer and disperse pressure, and avoid the support body 100 from making rigid contact with the inside of the flange during support, thereby preventing mechanical damage.

[0065] For example, the first flexible support member 210 may be adhered to the first end 111 using an adhesive, or may be fixed to the first end 111 using a clamp. The second flexible support member 220 may be adhered to the second end 121 using an adhesive, or may be fixed to the second end 121 using a clamp.

[0066] In some embodiments of the present application, the support body 100 may be provided with a first connecting plate 1111 on the end surface of the first end 111 , and the first flexible support member 210 is installed on the plate surface of the first connecting plate 1111 and is detachably connected to the first connecting plate 1111 .

[0067] For example, the first connecting plate 1111 can be integrally formed with the first end 111 of the support body 100, or can be connected to the first end 111 of the support body 100 by welding. The first connecting plate 1111 has a first mounting hole, and the first flexible support member 210 has a second mounting hole. A bolt or screw passes through the first mounting hole and is screwed into the second mounting hole to achieve a detachable connection between the first connecting plate 1111 and the first flexible support member 210.

[0068] Similarly, the support body 100 is provided with a second connecting plate 1211 on the end surface of the second end 121. The second flexible support member 220 is mounted on the surface of the second connecting plate 1211 and is detachably connected to the second connecting plate 1211. The connection method between the second connecting plate 1211 and the second flexible support member 220 is the same as the connection method between the first connecting plate 1111 and the first flexible support member 210.

[0069] The first connecting plate 1111 and the first flexible support member 210, as well as the second connecting plate 1211 and the second flexible support member 220, are all connected by bolts or screws. This provides additional fixing strength, making it suitable for use in high-load environments. Furthermore, the detachable connection facilitates subsequent adjustment, repair, and replacement, increasing the support structure's flexibility and simplifying maintenance and repair.

[0070] In some embodiments of the present application, the surface area of ​​the first connecting plate 1111 is greater than or equal to the surface area of ​​the first end 111, and the first flexible support member 210 covers the surface area of ​​the first connecting plate 1111. The surface area of ​​the second connecting plate 1211 is greater than or equal to the surface area of ​​the second end 121, and the second flexible support member 220 covers the surface area of ​​the second connecting plate 1211.

[0071] The larger connecting plate surface area provides a larger contact surface, thereby dispersing stress and improving the stability and load-bearing capacity of the support structure. Furthermore, the first flexible support member 210 covers the entire surface area of ​​the first connecting plate 1111, while the second flexible support member 220 covers the entire surface area of ​​the second connecting plate 1211. This increased surface area increases the coverage area of ​​the first flexible support member 210, and the contact area between the first and second flexible supports 210, 220, and the inner wall of the flange, reducing stress concentration, better absorbing and dispersing vibration, and lowering the risk of damage to the inner wall of the flange.

[0072] In some embodiments of the present application, the support body 100 includes a first support section 110 and a second support section 120. The second support section 120 includes a fixed section 122 and a telescopic section.

[0073] The fixed section 122 is connected to the first support section 110. The support body 100 may further include a third connecting plate 1221, which is positioned between the fixed section 122 and the first support section 110. For example, the third connecting plate 1221 may be provided at one end of the fixed section 122, near the end connected to the first support section 110, and the third connecting plate 1221 may also be provided at one end of the first support section 110, near the end connected to the fixed end. Both third connecting plates 1221 have mounting holes, through which bolts pass and are tightened with nuts to achieve the connection between the fixed section 122 and the first support section 110.

[0074] By providing the third connecting plate 1221 , the contact area between the first supporting segment 110 and the fixing segment 122 is increased, the connection strength is improved, and a stable connection between the first supporting segment 110 and the fixing segment 122 is ensured.

[0075] The end of the first supporting section 110 that is away from the fixed section 122 forms a first end 111 .

[0076] The telescopic section is connected to the end of the fixed section 122 away from the first support section 110 and can be extended or retracted relative to the fixed section 122. The end of the telescopic section away from the fixed section 122 forms the second end 121.

[0077] For example, the telescopic section can be a telescopic sleeve. Using sleeves of different diameters, the smaller sleeve is installed within the larger sleeve. A locking device, such as a pin, locking bolt, or clip, is provided between the sleeves to lock the smaller sleeve in place. By adjusting the extension or retraction length of the smaller sleeve, the length of the telescopic section can be adjusted, allowing for fine-tuning of the support structure's length.

[0078] Preferably, the telescopic section can be a jack 123. Jack 123 has a telescopic end 1231 that can extend or retract along the length of the support structure. The end of jack 123 facing away from telescopic end 1231 is connected to fixed section 122, and telescopic end 1231 is connected to second connecting plate 1211. By adjusting the length of telescopic end 1231, jack 123 fine-tunes the length of support body 100, enabling precise adjustment of the length of the support structure.

[0079] In summary, the support structure allows the length of the first support segment 110 to be adjusted based on the actual diameter of the wind turbine tower. The second support segment 120 connects to the first support segment 110, extending the first support segment 110. The fixed segment 122 of the second support segment 120 is used to connect to the first support segment 110, while the telescopic segment is used to fine-tune the length of the second support segment 120.

[0080] When in use, the first support section 110 and the second support section 120 of the support structure can be detachably connected, and the first support section 110 and the second support section 120 can be selected and matched according to the diameter of the cylinder, which is highly flexible and can achieve flexible adaptation to towers of different sizes.

[0081] The second support section 120 extends the length of the first support section 110. The fixed section 122 ensures a secure connection between the second support section 120 and the first support section 110. The telescopic section allows for fine-tuning of the support structure. This not only improves the versatility and adaptability of the support structure but also enhances installation precision and stability, ensuring reliable support for a variety of wind turbine tower diameters, simplifying the installation process, and improving construction efficiency.

[0082] Embodiments of the present application also provide a wind turbine tower assembly, comprising: a wind turbine tower and any of the aforementioned support structures provided in the embodiments of the present application. The wind turbine tower comprises a segment and a connecting piece, the connecting piece being disposed at the end of the segment and having a connecting cavity. The cavity wall of the connecting cavity and the inner wall of the segment form the circumferential inner wall of the wind turbine tower.

[0083] The support structure provided by any of the above-mentioned embodiments of the present application is arranged in the cylinder section and / or the connecting cavity, and the support structure has a first flexible support member and a second flexible support member, and the first flexible support member and the second flexible support member are both supported on the circumferential inner wall of the wind turbine tower.

[0084] An embodiment of the present application provides a wind turbine tower assembly, which avoids deformation due to position deviation of deformation control by applying the support assembly provided by the embodiment of the present application, thereby improving the quality assurance of the wind turbine tower.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
