Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a tower anti-deformation device. Background Art

[0002] Towers are widely used in wind power, transmission towers and other fields. They are an important component of wind turbines. Their main function is to support the nacelle and blades of wind turbines so that they reach the appropriate height to capture wind energy. Towers usually consist of several sections, and each section is stored and transported separately. During installation, adjacent sections are bolted together through end face flange holes. During the storage and transportation of the tower, due to bumps and other reasons, it is very easy to cause the sections to deform, causing parameters such as the verticality and roundness of the tower to change, making it impossible to install the tower. The deformation of the tower will pose a huge safety hazard to the lifting of the entire machine and the movement of the unit. Therefore, there is a need for a tooling to prevent the deformation of the tower during the storage and transportation of the tower. The existing related tooling to prevent tower deformation has the following defects: the tooling size is fixed, but the cross-sectional dimensions of the tower sections are different, and each section needs to be equipped with multiple tooling of different sizes, which results in a high overall cost of use.

[0006] The extension members correspond to the support members one by one and are detachably connected, and a plurality of second through holes are formed on each extension member, and the second through holes are arranged at intervals at least along the length direction of the support member corresponding to the extension member;

[0007] The sum of the number of the first through holes and the second through holes in the length direction of the support member is consistent with the number of cylinder sections of the tower.

[0008] In some embodiments, an area of ​​each of the first through hole and / or the second through hole is larger than an area of ​​an end face flange hole of a tower segment.

[0009] In some embodiments, each of the first through holes is further arranged at intervals along the width direction of the support member where it is located; and / or each of the second through holes is further arranged at intervals along the width direction of the support member corresponding to the extension member where it is located.

[0012] In some embodiments, each of the second support components forms an acute angle with the first support component; and / or, two of the second support components and the other two second support components are symmetrically arranged with the first support component as the axis of symmetry.

[0013] In some embodiments, gaps are formed between adjacent support members in the first support assembly and / or the second support assembly, and the bracket further includes a plurality of reinforcement members, each of which is located in one of the gaps and respectively connects adjacent support members.

[0016] In some embodiments, the length of each of the extension members is much smaller than the length of each of the support members.

[0017] The present invention has at least the following beneficial effects: since the first through holes on each support member are arranged at intervals along the length direction of the support member on which they are located (corresponding to the radial direction of the tower), and the second through holes on each extension member are arranged at intervals along the length direction of the support member corresponding to the extension member on which they are located (corresponding to the radial direction of the tower), the sum of the number of the first through holes and the second through holes in the length direction of the support member is consistent with the number of cylinder sections of the tower, so the first through holes and the second through holes can correspond one-to-one to the end faces of cylinder sections with different cross-sectional dimensions, thereby, by selecting through holes in appropriate positions from the first through holes and the second through holes, a tower anti-deformation device can be simultaneously adapted to the end faces of each cylinder section, and a tower anti-deformation device can be suitable for the anti-deformation transportation and storage of each section of the entire tower, without the need to equip each cylinder section with multiple tooling of different sizes, thereby reducing the overall cost of use.

[0027] The terms "first," "second," "third," etc., are used solely to facilitate description of the present technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first," "second," "third," etc. may explicitly or implicitly include one or more of such features. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] like Figure 1 As shown in FIG, the tower of a wind turbine (offshore wind turbine or onshore wind turbine) generally comprises several axially connected cylinder sections, with adjacent cylinder sections connected together by bolts. The cross-sectional dimensions of each cylinder section are different. Specifically, Figure 1 Taking the tower shown as an example, this tower has four sections, and the tower is in an inverted cone shape, meaning that the cross-sectional dimensions of the tower gradually decrease from bottom to top. The four sections are defined as, from bottom to top, the first section 11, the second section 12, the third section 13, and the fourth section 14. The first section 11 is generally (hollow) cylindrical, with cross-sectional dimensions that are uniform at all axial positions. The lower cross-sectional dimensions of the second section 12 are equal to the upper cross-sectional dimensions of the first section 11, and the upper cross-sectional dimensions of the second section 12 are smaller than the lower cross-sectional dimensions. The lower cross-sectional dimensions of the third section 13 are equal to the upper cross-sectional dimensions of the second section 12, and the upper cross-sectional dimensions of the third section 13 are smaller than the lower cross-sectional dimensions. The lower cross-sectional dimensions of the fourth section 14 are equal to the upper cross-sectional dimensions of the third section 13, and the upper cross-sectional dimensions of the fourth section 14 are smaller than the lower cross-sectional dimensions. The number of sections is typically four, but other numbers, such as three or five, are not excluded.

[0029] See also Figure 2 and Figure 3 The tower anti-deformation device of the present invention is used to be installed on any end face of any tower segment 10. That is, the present invention aims to design a tower anti-deformation device that can adapt to each tower segment 10. When the tower segment 10 is transported, a tower anti-deformation device is configured on each of its two end faces, or a tower anti-deformation device is configured on one of its end faces, which can provide reliable support for the tower segment 10 and effectively prevent the tower segment 10 from being deformed by external forces during transportation. Specifically:

[0030] Please also read Figures 2 to 4An embodiment of the tower anti-deformation device of the present invention includes a bracket and a plurality of extension members 30. The bracket includes a plurality of support members 20, which are arranged in a circumferential direction. The circumferential direction can refer to the circumferential direction of the tower. Each support member 20 has a length direction L and a width direction W.

[0031] A plurality of first through holes 201 are formed on each support member 20, and each of the first through holes 201 is arranged at intervals along at least the length direction L of the support member 20 on which it is located. The extension members 30 correspond to the support members 20 one by one and are detachably connected. That is, each extension member 30 is connected to a corresponding support member 20, and the number of extension members 30 and support members 20 is the same. A plurality of second through holes 302 are formed on each extension member 30, and each of the second through holes 302 is arranged at intervals along at least the length direction L of the support member 20 corresponding to the extension member 30 on which it is located. When the tower anti-deformation device is installed on the end face of the cylinder segment, the length direction L of each support member 20 is consistent with the radial direction of the cylinder segment of the tower. The width direction W of the support member 20 is perpendicular to the length direction L.

[0032] Each first through hole 201 and each second through hole 302 corresponds to the end face flange hole 101 of the tower section 10. Figure 5 and Figure 6 As shown, further, the tower anti-deformation device also includes a plurality of first fasteners 41 and a plurality of second fasteners 42. Each first fastener 41 is detachably inserted into one of the first through holes 201 and one of the end face flange holes 101 of the tower tube segment 10, thereby fixing the support member 20 and the end face of the tube segment 10 together. Alternatively, in other embodiments, each first fastener 41 is detachably inserted into one of the second through holes 302 and one of the end face flange holes 101 of the tower tube segment 10, thereby fixing the extension member 30 and the end face of the tube segment 10 together. Figure 1 As shown, the cross-section of the barrel segment 10 near the top is smaller, so the extension member 30 can be omitted and the support member 20 can be fastened to the end surface of the barrel segment 10. The cross-section of the barrel segment 10 near the bottom is larger, and if the support member 20 is not long enough, the extension member 30 can be connected to the support member 20 and then fastened to the end surface of the barrel segment 10. Each second fastener 42 is detachably provided through the extension member 30 and the support member 20 to detachably connect the extension member 30 and the support member 20 together.

[0033] Please continue reading Figures 2 to 4 The sum of the number of the first through holes 201 and the second through holes 302 in the length direction L of the support member 20 is consistent with the number of the tower sections 10. Figure 4In the illustrated embodiment, along the length direction L of the support member 20, there are two first through holes 201 and two second through holes 302, with each of the four through holes corresponding to the four cylinder segments 10. As described above, the cross-sectional dimensions of the tower gradually decrease from bottom to top, and the cross-sectional dimensions of the first tower at the bottom are equal at both ends. Therefore, the four towers have four end surfaces with different cross-sectional dimensions, and the number of tower segments 10 matches the number of end surfaces with different cross-sectional dimensions. Therefore, the sum of the number of the first through holes 201 and the second through holes 302 in the length direction L of the support member 20 is consistent with the number of cylinder segments 10 of the tower, and the first through holes 201 and the second through holes 302 can correspond one-to-one to the end faces of the cylinder segments 10 with different cross-sectional sizes. Therefore, by selecting through holes in appropriate positions from the first through holes 201 and the second through holes 302, one tower anti-deformation device can be simultaneously adapted to the end faces of each cylinder segment 10. One tower anti-deformation device can be suitable for the anti-deformation transportation and storage of each section of the cylinder segments 10 of the entire tower, without the need to equip each cylinder segment 10 with multiple tooling of different sizes, thereby reducing the overall cost of use.

[0034] To sum up, since the first through holes 201 on each support member 20 are arranged at intervals along the length direction L of the support member 20 (corresponding to the radial direction of the tower), and the second through holes 302 on each extension member 30 are arranged at intervals along the length direction L of the support member 20 corresponding to the extension member 30 (corresponding to the radial direction of the tower), the sum of the number of the first through holes 201 and the second through holes 302 in the length direction L of the support member 20 is consistent with the number of cylinder segments 10 of the tower, so the first through holes 201 and the second through holes 302 can correspond one-to-one to the end faces of the cylinder segments 10 with different cross-sectional dimensions. Therefore, by selecting through holes in appropriate positions from the first through holes 201 and the second through holes 302, a tower anti-deformation device can be simultaneously adapted to the end faces of each cylinder segment 10, and a tower anti-deformation device can be suitable for the anti-deformation transportation and storage of each section of the cylinder segment 10 of the entire tower, and can be reused repeatedly without the need to equip each cylinder segment 10 with multiple tooling of different sizes, thereby reducing the overall cost of use. Moreover, since the extension piece 30 and the support piece 20 correspond one to one and are detachably connected, for different sections of the tower tube segment 10, the extension piece 30 can be selected for disassembly and assembly according to the end face cross-sectional size of the tube segment 10. Therefore, the protruding length of the bracket relative to the tube segment 10 of the tower tube will not be too long, thereby avoiding collision with objects around the tube segment 10.

[0035] In some embodiments, the length of each extension member 30 is much smaller than the length of each support member 20 , so the extension member 30 is very convenient to assemble and disassemble, and since the extension member 30 is smaller in length after disassembly, it is very easy to store.

[0036] In some embodiments, the area of ​​each first through-hole 201 and second through-hole 302 is larger than the area of ​​the end flange hole 101 of the tower segment 10. Alternatively, in other embodiments, only the area of ​​each first through-hole 201 is larger than the area of ​​the end flange hole 101 of the tower segment 10; or, in still other embodiments, only the area of ​​each second through-hole 302 is larger than the area of ​​the end flange hole 101 of the tower segment 10. That is, the first through-hole 201 and / or the second through-hole 302 have a certain margin relative to the end flange hole 101 of the tower segment 10. This prevents minor deformation that could make fastener installation and removal difficult, thereby ensuring that the end flange hole 101 of the tower segment 10 is not damaged, while also maintaining circumferential deformation protection for the tower segment 10.

[0037] like Figure 4 As shown, in some embodiments, each first through hole 201 is further spaced apart along the width direction W of the support member 20 in which it is located. Each second through hole 302 is further spaced apart along the width direction W of the support member 20 in which it is located, corresponding to the extension member 30 in which it is located. That is, along the width direction W of the support member 20, at least two first through holes 201 are spaced apart, and at least two second through holes 302 are spaced apart. Both the first through holes 201 and the second through holes 302 along the width direction W of the support member 20 can correspond to the end face flange holes 101 of the barrel segment 10 and are connected via the first fasteners 41 and the second fasteners 42. Thus, the number of first through holes 201 and second through holes 302 can be increased, and the number of first fasteners 41 and second fasteners 42 can be correspondingly increased, thereby increasing the number of connection points between the support member 20 and the extension member 30 and the end face of the barrel segment 10, thereby enhancing the fastening between the two and improving the anti-deformation protection capability. In some other embodiments, only the first through holes 201 may be arranged at intervals along the width direction W of the support member 20 ; or only the second through holes 302 may be arranged at intervals along the width direction W of the support member 20 .

[0038] like Figure 4 As shown, in some embodiments, the center line Y of at least two first through holes 201 spaced apart along the width direction W of the support member 20 is not parallel to the width direction W of the support member 20. Similarly, the center line Y of at least two second through holes 302 spaced apart along the width direction W of the support member 20 is not parallel to the width direction W of the support member 20 in which they are located. Thus, the arrangement trajectory of the first through holes 201 and the second through holes 302 spaced apart along the width direction W of the support member 20 corresponds to the arrangement trajectory (slightly curved) of the end face flange holes 101 of the barrel segment 10, thereby ensuring a one-to-one correspondence between each first through hole 201 (or second through hole 302) in the width direction W of the support member 20 and the end face flange hole 101 of the barrel segment 10.

[0039] like Figure 2 and Figure 3 As shown, in the first embodiment, the bracket includes a first support assembly 21 and at least four second support assemblies 22. That is, the number of second support assemblies 22 can be four or more. The first support assembly 21 includes at least two mutually parallel support members 20, and each second support assembly 22 also includes at least two mutually parallel support members 20. That is, two of the multiple support members 20 are parallel to each other to form a first support assembly 21. Another two of the multiple support members 20 are parallel to each other to form a second support assembly 22, and another two support members 20 are parallel to each other to form another second support assembly 22, and so on. At least eight support members 20 define a total of at least four second support assemblies 22. Each second support assembly 22 is connected to the first support assembly 21 respectively.

[0040] like Figure 2 and Figure 3 In the first embodiment shown, each second support assembly 22 forms an acute angle with the first support assembly 21. Specifically, each support member 20 of each second support assembly 22 forms an acute angle with the first support assembly 21. Furthermore, two of the second support assemblies 22 are arranged symmetrically with the other two second support assemblies 22 about the first support assembly 21. Specifically, two of the second support assemblies 22 are mirror-symmetrical with the other two second support assemblies 22 about the first support assembly 21. The four second support assemblies 22 are located at the upper left corner, upper right corner, lower left corner, and lower right corner of the first support assembly 21, respectively. Thus, the first support assembly 21 serves as the support point for each of the second support assemblies 22. Each of the second support assemblies 22 is spread out circumferentially around the barrel segment 10, with a total of twelve support members 20 arranged at intervals along the circumference. This effectively distributes stress on the barrel segment 10 circumferentially, preventing deformation under stress and providing effective anti-deformation protection.

[0041] like Figure 2 and Figure 3 In the first embodiment shown, spaces are formed between adjacent support members 20 in the first support assembly 21, and spaces are also formed between adjacent support members 20 in the second support assembly 22. The bracket further includes a plurality of reinforcement members 50, each of which is located within one of the spaces and connects adjacent support members 20. In other embodiments, spaces may be formed only between adjacent support members 20 in the first support assembly 21, or only between adjacent support members 20 in the second support assembly 22. The reinforcement members 50 serve to enhance the overall rigidity of the bracket.

[0042] like Figure 7As shown, in the second embodiment, the bracket is in the shape of a "M". There are eight support members 20 arranged at intervals along the circumferential direction, and the length directions L of adjacent support members 20 form an acute angle.

[0043] Figure 2 and Figure 3 In the second embodiment shown, and Figure 7 In the second embodiment shown, there are three types of support members 20 with different length directions L. The length directions L of the three types of support members 20 form an angle less than or equal to 90° between each other.

[0044] Models of the tower anti-deformation devices of the first and second embodiments were constructed using computer software, and finite element analysis was performed on the models of the first and second embodiments, respectively, resulting in the data in Table 1 below. Table 1 shows the deformation and stress under corresponding operating conditions when the first and second embodiments, respectively, were installed on the end faces of tower segments.

[0045]

[0046]

[0047] Table 1

[0048] In Table 1, the working condition 1 of the top section tower refers to the support surface spacing of 12500mm, the working condition 2 refers to the support surface spacing of 35500mm, and the working condition 3 refers to the tower over-mooring condition; the working condition 1 of the middle and upper section tower refers to the support surface spacing of 12500mm; the working condition 2 refers to the support surface spacing of 34980mm, and the working condition 3 refers to the tower over-mooring condition; the working condition 1 of the middle and lower section tower refers to the support surface spacing of 12500mm; the working condition 2 refers to the support surface spacing of 22500mm, and the working condition 3 refers to the tower over-mooring condition.

[0049] The finite element calculation results in Table 1 show that the maximum overall stress of the tower anti-deformation device in the second embodiment is 140.8 MPa, located at the tower edge, which is less than the material's allowable stress of 231 MPa and meets the design requirements for strength. The maximum tower deformation is 13.88 mm, located in the middle of the upper-middle tower section. The maximum deformation of the flange surface is 13 mm, located on the upper flange surface of the upper-middle tower section. The maximum deformation of the tower anti-deformation device is 8.55 mm, located on the upper flange surface of the upper-middle tower section. All of these deformations are elastic, but the deformation is relatively large. The maximum overall stress of the tower anti-deformation device in the first embodiment is 111.73 MPa, located at the contact point of the support surface in the upper-middle tower section, which is less than the material's allowable stress of 231 Pa and meets the design requirements for strength. The maximum tower deformation is 24.05 mm, located in the middle of the top tower section. The maximum deformation of the flange surface is 4.35 mm, located on the upper flange surface of the upper-middle tower section. The maximum deformation of the tower anti-deformation device is 7.12 mm, located at the connection between the lower flange surface of the lower-middle tower section. The above deformations are all elastic deformations and meet the design requirements.

[0050] According to the above table, the M-shaped tower anti-deformation device (second embodiment) and Figure 2 、 Figure 3 The tower anti-deformation device (first embodiment) shown meets the strength and stiffness requirements. The maximum deformation of the tower flange surface installed with the second embodiment is 13mm, while the maximum deformation of the tower flange surface installed with the first embodiment is 4.35mm. This shows that the first embodiment significantly reduces tower flange deformation and effectively prevents tower deformation.

[0051] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
