Description

Technical Field

[0001] This application relates to the field of wind turbine installation technology, and in particular to a positioning device and wind turbine installation equipment. Background Technology

[0002] When installing offshore wind turbines, it is typically necessary to assemble the prefabricated transformer and nacelle on-site on the platform deck before hoisting them together to their designated positions on the tower. In one existing on-site installation scheme, a high-level nacelle fixture is required to support both the bow and stern of the nacelle, and another fixture is needed to support the prefabricated transformer. The three high-level nacelle fixtures should have good positional accuracy to ensure the efficiency, convenience, and safety of subsequent assembly of the prefabricated transformer and nacelle. Currently, the positioning of these three high-level nacelle fixtures is usually done manually, one by one, using a line-laying method. This method is inefficient and has relatively low positioning accuracy. Summary of the Invention

[0003] To address the aforementioned issues, embodiments of this application provide a positioning device and a wind turbine installation equipment.

[0004] In a first aspect, embodiments of this application provide a positioning device, including: The positioning base is provided in multiple ways, and the multiple positioning bases are arranged at intervals in at least two columns and at least two rows. The positioning bases in any row are arranged along a first direction, and the positioning bases in any column are arranged along a second direction. The first direction and the second direction are orthogonal. The positioning components are provided in multiples. Each positioning component is provided between two adjacent positioning bases in the same row and column. The multiple positioning components form a positioning space, and each positioning component is provided with a positioning mark. The positioning space is used to place the high-level tooling in the cabin. The positioning mark is used to align with the feature mark of the high-level tooling in the first direction and the second direction.

[0005] Optionally, the positioning base includes a positioning block for fixed welding to the load-bearing structure.

[0006] Optionally, the positioning element includes a telescopic rod, which is connected to two adjacent positioning blocks in the same row or column, and the telescopic rod can extend or shorten along its own extension direction.

[0007] Optionally, the positioning block has a threaded hole, and the telescopic rod has a threaded section, which is threadedly connected to the threaded hole.

[0008] Optionally, the positioning block has a cuboid structure, and the threaded hole is located at the center of the rectangular surface of the positioning block.

[0009] Optionally, the plurality of positioning elements form at least two positioning spaces, and the at least two positioning spaces are respectively used to place different cabin high-level tooling.

[0010] Optionally, eight positioning bases are provided, which are distributed in four columns along the first direction and in two rows along the second direction. A positioning element is provided between two adjacent positioning bases in the same row and column. The positioning space includes a first positioning space, a second positioning space, and a third positioning space, and the first positioning space, the second positioning space, and the third positioning space are arranged along the first direction.

[0011] Optionally, the extension range of the positioning members that extend along the second direction constituting the first positioning space, the second positioning space, and the third positioning space is the same.

[0012] Optionally, the telescopic range of the positioning member extending along the first direction constituting the third positioning space is different from that of the other positioning members, and the length of the positioning member extending along the first direction constituting the third positioning space is smaller than that of the other positioning members.

[0013] Optionally, the positioning mark is painted on the positioning element.

[0014] Secondly, embodiments of this application provide a wind turbine installation device, which includes any of the positioning devices described in the first aspect and a nacelle high-position tooling. The nacelle high-position tooling is disposed within the positioning space of the positioning device. The nacelle high-position tooling has a feature mark, which is aligned with the positioning mark in the positioning device in a first direction and a second direction.

[0015] Optionally, the high-level tooling for the nacelle includes a first tooling, a second tooling, and a third tooling. The first tooling is adapted to support the bow of the nacelle, the second tooling is adapted to support the box-type transformer, and the third tooling is adapted to support the tail of the nacelle. The positioning device includes three positioning spaces, with the first tooling, the second tooling, and the third tooling each disposed within one of the positioning spaces; the feature marks of the first tooling, the second tooling, and the third tooling are respectively aligned with the positioning marks corresponding to their respective positioning spaces.

[0016] In some implementations of this application, the positioning device includes a positioning base and positioning elements. The positioning bases are distributed in at least two rows and at least two columns, and positioning elements are provided between adjacent positioning bases in the same row and column. The positioning elements enclose a positioning space, within which the high-level tooling in the cabin is located. The positioning mark on the positioning element is aligned with the feature mark on the high-level tooling in the cabin in a first direction and a second direction. The positioning base provides a reliable positional basis for the positioning elements, and the positioning mark on the positioning elements provides a reliable positioning reference for the high-level tooling in the cabin. Compared to the positioning method of manual line laying, positioning using the positioning device described in this application only requires ensuring that the positioning mark on the positioning element is aligned with the feature mark on the high-level tooling in the cabin to achieve the positioning of the high-level tooling. This avoids operational errors caused by manual line laying, which is beneficial to improving the positioning accuracy of the high-level tooling in the cabin. Furthermore, it simplifies the positioning process and avoids the low positioning efficiency caused by manual line laying.

[0019] Embodiments of the present invention will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0020] The nacelle is the power and control center of an existing wind turbine, integrating devices responsible for power generation, transmission, control, and protection. The prefabricated transformer is one of the core components of the nacelle, responsible for core power conversion, power on / off, power distribution, relay protection, and monitoring auxiliary functions. Therefore, the reliable installation of the prefabricated transformer within the nacelle is always a key focus during on-site wind turbine installation.

[0021] In one existing on-site installation scheme, the prefabricated substation needs to be assembled with the nacelle first, and then the two are hoisted together to a predetermined position on the tower. The prefabricated substation is large and heavy, and when docking with the nacelle, lifting equipment and high-level nacelle fixtures are usually required to ensure the accuracy, stability, and safety of the docking. Specifically, during the assembly process, three different high-level nacelle fixtures are needed to support both the prefabricated substation and the nacelle. One high-level nacelle fixture is needed at the head and tail of the nacelle to support the weight of the nacelle and substation assembly, and a separate high-level nacelle fixture is also required for the prefabricated substation to be carried and hoisted.

[0022] During the assembly phase, the three nacelle high-level tooling fixtures are positioned relatively far apart, often requiring manual positioning and layout. This method is not only cumbersome and inefficient, but also prone to cumulative errors, making it difficult to guarantee the relative positional accuracy of the three nacelle high-level tooling fixtures. If the positioning deviation of the three nacelle high-level tooling fixtures is too large, the nacelle cannot be accurately placed on the high-level tooling fixtures, requiring readjustment of the three nacelle high-level tooling fixtures. During the readjustment process, the nacelle needs to be suspended in mid-air, which not only occupies scarce hoisting equipment, but also increases the difficulty of wind turbine installation, resulting in a waste of time, manpower, and resources. In offshore operations, this can easily lead to missing the wind turbine hoisting window, forcing the wind turbine installation work to be suspended midway, and also drastically increasing construction safety risks and operating costs.

[0023] Therefore, this application provides a positioning device 1 to overcome many problems existing in the prior art.

[0024] refer to Figure 1In a first aspect, embodiments of this application provide a positioning device 1 for positioning the high-level tooling 2 of the nacelle in a wind turbine generator set. Specifically, the positioning device 1 includes a positioning base 11 and a positioning element 12.

[0025] The positioning base 11 serves as the mounting foundation for the positioning element 12 and is used to connect with the supporting structure of the positioning device 1. In the embodiments described in this application, the supporting structure on which the positioning base 11 is located can be ground or other supporting structures. In an offshore installation scenario, the supporting structure can specifically be the deck of an offshore platform. Multiple positioning bases 11 are provided, arranged in at least two columns along a first direction X, and in at least two rows along a second direction Y. Any row of positioning bases 11 is arranged along the first direction X, and any column of positioning bases 11 is arranged along the second direction Y. The first direction X and the second direction Y are orthogonal, meaning the included angle between them is 90 degrees.

[0026] refer to Figure 1 The positioning element 12 is the main structure providing positional reference for the high-level tooling 2 in the cabin. Multiple positioning elements 12 are provided, with one positioned between each pair of adjacent positioning bases 11 in the same row and column. These positioning elements 12 form a positioning space 13, within which the high-level tooling 2 is positioned. Positioning marks 12a are provided on the positioning elements 12. These marks 12a can be markings painted on the positioning elements 12, or they can be structures such as collars, protrusions, or magnets on the positioning elements 12. The positioning marks 12a can be aligned with the feature marks 2a of the high-level tooling 2 in the first direction X and the second direction Y to achieve positioning of the high-level tooling 2 in both directions X and Y. The feature marks 2a of the high-level tooling 2 can be structures such as holes or protrusions on the high-level tooling 2, or they can be markings painted on the high-level tooling 2, attracted magnets, or pasted labels.

[0027] For example, four positioning bases 11 can be provided, arranged in two columns along the first direction X and in two rows along the second direction Y. A positioning element 12 is provided between each pair of positioning bases 11 in the same row, with the extension direction of the positioning element 12 along the first direction X. A positioning element 12 is also provided between each pair of positioning bases 11 in the same column, with the extension direction of the positioning element 12 along the second direction Y. The four positioning elements 12 form a rectangular positioning space 13, within which the cabin high-position tooling 2 is positioned. In this case, the positioning mark 12a on the positioning element 12 extending along the first direction X can be aligned with the corresponding feature mark 2a on the cabin high-position tooling 2 to achieve positioning of the cabin high-position tooling 2 in the first direction X. The positioning mark 12a on the positioning member 12 extending along the second direction Y can be aligned with the corresponding feature mark 2a on the cabin high-position tooling 2 to achieve the positioning of the cabin high-position tooling 2 in the second direction Y.

[0028] For example, six positioning bases 11 can be provided, arranged in three columns along the first direction X, and in two rows along the second direction Y. A positioning element 12 is provided between each pair of positioning bases 11 in the same row, with the extension direction of the positioning element 12 along the first direction X. A positioning element 12 is provided between each pair of positioning bases 11 in the same column, with the extension direction of the positioning element 12 along the second direction Y. The seven positioning elements 12 form two rectangular positioning spaces 13, each containing a cabin high-position tooling 2. The positioning of the cabin high-position tooling 2 and the positioning elements 12 can be referred to the previous description and will not be repeated here.

[0029] refer to Figure 1 For example, eight positioning bases 11 can be provided, arranged in four columns along the first direction X, and in two rows along the second direction Y. A positioning element 12 is provided between each pair of positioning bases 11 in the same row, with the extension direction of the positioning element 12 along the first direction X. A positioning element 12 is provided between each pair of positioning bases 11 in the same column, with the extension direction of the positioning element 12 along the second direction Y. The ten positioning elements 12 form three rectangular positioning spaces 13, and each of the three rectangular positioning spaces 13 contains a cabin high-position tooling 2. The positioning of the cabin high-position tooling 2 and the positioning elements 12 can be referred to the previous description, and will not be repeated here.

[0030] In summary, there are many ways to set the number and arrangement of the positioning base 11 and the positioning component 12, which will not be listed and elaborated here.

[0031] Compared to manual layout positioning, the positioning base 11 described in this application provides a reliable positional foundation for the positioning component 12. This eliminates the repetitive alignment process required during manual layout and helps the positioning component 12 overcome the influence of the environment on positioning accuracy. The positioning mark 12a on the positioning component 12 provides a reliable positioning reference for the cabin high-level tooling 2. Compared to manual layout, this avoids both manual operation errors and cumulative errors, as well as the impact of complex operating environments on positioning accuracy. Therefore, compared to manual layout positioning, using the positioning device 1 described in this embodiment only requires ensuring that the positioning mark 12a of the positioning component 12 is aligned with the feature mark 2a on the cabin high-level tooling 2 to achieve positioning of the cabin high-level tooling 2. This avoids the operational and cumulative errors caused by manual layout, thus improving the positioning accuracy of the cabin high-level tooling 2. Furthermore, it simplifies the positioning process, avoiding the cumbersome steps and low positioning efficiency associated with manual layout.

[0032] The improved positioning accuracy prevents excessive positioning deviations in the nacelle high-position tooling 2, ensuring the nacelle is accurately positioned on it. This minimizes the need for readjusting the position of the high-position tooling 2, saving on hoisting equipment, reducing installation difficulties, and avoiding waste of time, manpower, and resources. In offshore operations, this ensures the wind turbine installation can proceed steadily and orderly within the hoisting window, reducing the possibility of forced interruptions and minimizing construction safety risks and operating costs.

[0033] refer to Figure 1 In some embodiments of this application, the positioning base 11 optionally includes a positioning block 111, which is used for fixed welding to the supporting structure. Exemplarily, in the scenario of installing wind turbines at sea, the positioning block 111 can be a metal block made of cast iron or other metal materials. The shape and size of the positioning block 111 can be configured in various ways, which will not be elaborated here. The positioning block 111 can be spot-welded to the deck of the offshore operating platform to ensure a reliable connection between the positioning block 111 and the offshore operating platform, which serves as the supporting structure. Fixed welding makes it easier to ensure the positional accuracy of the positioning block 111. Based on the fixed welding method between the positioning block 111 and the supporting structure, the positioning block 111 can provide accurate and reliable positional assurance for the positioning component 12. This helps the positioning component 12 overcome the influence of the environment on positioning accuracy, thus helping to ensure the positioning accuracy of the positioning device 1. Simultaneously, since the positioning block 111 is fixedly welded to the supporting structure, it can be reused when installing wind turbines of the same specifications, thereby improving the installation efficiency when installing wind turbines of the same specifications in batches.

[0034] refer to Figure 1 In some embodiments of this application, optionally, the positioning member 12 includes a telescopic rod 121, which is connected to two adjacent positioning blocks 111 in the same row or column. The telescopic rod 121 can extend or shorten along its own extension direction to adjust its length according to the distance between the positioning blocks 111. The telescopic rod 121 can specifically adopt an existing telescopic structure. For example, the telescopic rod 121 can have at least two rod sections, which are nested sequentially. In use, the length of the telescopic rod 121 can be adjusted by pulling out or pushing back a portion of the rod section. Compared to a rigid rod, the use of a telescopic rod 121 in the positioning member 12 can reduce interference and facilitate the installation of the telescopic rod 121 and the positioning blocks 111. On the other hand, the telescopic rod 121 can adapt to changes in the distance between the positioning blocks 111 and can be applied to the installation of wind turbine units of different specifications. Therefore, the use of a telescopic rod 121 in the positioning member 12 helps to ensure the interchangeability of the positioning member 12, thereby reducing the implementation cost of the positioning device 1 when installing wind turbine units of different specifications. The dimensions of the telescopic pole 121 can be set according to actual needs. For example, the cross-section of the telescopic pole 121 can be a circle with a diameter of 30mm, and the length of the telescopic pole 121 can be 5m~10m or 2m~4m.

[0035] refer to Figure 2 In some embodiments of this application, optionally, the positioning block 111 has a threaded hole 1111, and the telescopic rod 121 has a threaded section 1211, which is threadedly connected to the threaded hole 1111. In other words, the telescopic rod 121 and the positioning block 111 are connected by a threaded engagement. This facilitates the installation of the telescopic rod 121 and also ensures a good and reliable connection between the telescopic rod 121 and the positioning block 111 based on the self-locking property of the thread. This helps the positioning component 12 overcome the influence of the environment on the positioning accuracy and helps ensure the positioning accuracy of the positioning device 1. The specifications of the threaded section 1211 on the telescopic rod 121 and the threaded hole 1111 on the positioning block 111 can be set according to actual needs, and will not be elaborated here.

[0036] refer to Figure 2In some embodiments of this application, the positioning block 111 may optionally be a cuboid structure. The specifications of the positioning block 111 can be set according to actual needs. For example, the length, width, and height of the positioning block 111 may be 200mm, 200mm, and 100mm, respectively. The cuboid positioning block 111 has six rectangular faces, and the threaded hole 1111 is located at the center of each rectangular face, which is also the intersection of the diagonals of the rectangular faces. The cuboid shape of the positioning block 111 facilitates its positioning and installation. Furthermore, the threaded hole 1111 being located at the center of the rectangular face of the positioning block 111 helps ensure its positioning. This facilitates the positioning of the positioning member 12, helps ensure the positional accuracy of the positioning member 12, and thus provides convenience and accuracy for setting the positioning mark 12a on the positioning member 12.

[0037] refer to Figure 1 In some embodiments of this application, optionally, multiple positioning elements 12 enclose at least two positioning spaces 13, and the at least two positioning spaces 13 are respectively used to place different cabin high-level tooling 2. Different cabin high-level tooling 2 can be cabin high-level tooling 2 of the same specification from different individuals, or cabin high-level tooling 2 of different individuals and different specifications. Exemplarily, six positioning bases 11 can be provided, the six positioning bases 11 are arranged in three columns along the first direction X, and the six positioning bases 11 are arranged in two rows along the second direction Y. A positioning element 12 is respectively provided between two positioning bases 11 in the same row, and the extension direction of the positioning element 12 is set along the first direction X. A positioning element 12 is respectively provided between two positioning bases 11 in the same column, and the extension direction of the positioning element 12 is set along the second direction Y. The above seven positioning elements 12 enclose two rectangular positioning spaces 13, and one cabin high-level tooling 2 is provided in each of the two rectangular positioning spaces 13.

[0038] Alternatively, by way of example, eight positioning bases 11 may be provided, arranged in four columns along the first direction X, and in two rows along the second direction Y. A positioning element 12 is provided between each two positioning bases 11 in the same row, with the extension direction of the positioning element 12 along the first direction X. A positioning element 12 is provided between each two positioning bases 11 in the same column, with the extension direction of the positioning element 12 along the second direction Y. The ten positioning elements 12 form three rectangular positioning spaces 13, and each of the three rectangular positioning spaces 13 contains a cabin high-position tooling 2.

[0039] Multiple positioning components 12 form at least two positioning spaces 13, and different cabin high-level tooling 2s are placed in each of the at least two positioning spaces 13. This means that each cabin high-level tooling 2 can be positioned independently in its corresponding positioning space 13. This avoids mutual interference between the positioning operations of different cabin high-level tooling 2s, and helps ensure that each cabin high-level tooling 2 has a good positioning effect. At the same time, this also improves the convenience of positioning different cabin high-level tooling 2s, thereby improving the positioning efficiency of the cabin high-level tooling 2s.

[0040] refer to Figure 1 In some embodiments of this application, optionally, eight positioning bases 11 are provided, arranged in four columns along the first direction X and in two rows along the second direction Y. A positioning element 12 is provided between each pair of adjacent positioning bases 11 in the same row and column, meaning there are a total of eight positioning elements 12 in the positioning bases 11. The eight positioning elements 12 form three positioning spaces 13, which are named first positioning space 131, second positioning space 132, and third positioning space 133 for easy distinction. The first positioning space 131, second positioning space 132, and third positioning space 133 are arranged along the first direction X. This allows the positioning device 1 to better correspond to the three nacelle high-level tooling 2 corresponding to the nacelle and box-type transformer during wind turbine installation. The three high-level tooling fixtures 2 corresponding to the nacelle and the box-type transformer can each be positioned independently within their respective positioning spaces 13, thus avoiding mutual interference between the positioning operations of different high-level tooling fixtures 2 and ensuring that each high-level tooling fixture 2 can achieve a good positioning effect. At the same time, this also improves the convenience of positioning different high-level tooling fixtures 2, thereby improving the positioning efficiency of the high-level tooling fixtures 2.

[0041] refer to Figure 1 Specifically, during wind turbine installation, the three high-level nacelle fixtures 2 corresponding to the nacelle and prefabricated transformer are: the first fixture 21, the second fixture 22, and the third fixture 23. The first fixture 21 supports the nacelle head, which is the connection point between the nacelle and the fourth tower section of the wind turbine; therefore, the first fixture 21 has a cylindrical shape adapted to the nacelle head. The second fixture 22 can be an open cuboid frame structure. The prefabricated transformer is placed inside the second fixture 22 before installation, and the second fixture 22 is used for lifting the prefabricated transformer. The third fixture 23 can be a frame structure with outriggers. The third fixture 23 uses the outriggers to support the tail of the nacelle, which is the other part of the nacelle relative to the head in its extension direction. The first fixture 21 is located in the first positioning space 131, the second fixture 22 is located in the second positioning space 132, and the third fixture 23 is located in the third positioning space 133.

[0042] refer to Figure 1 In some embodiments of this application, optionally, the extension and retraction ranges of the positioning members 12 extending along the second direction Y that constitute the first positioning space 131, the second positioning space 132, and the third positioning space 133 are the same. In other words, two of the positioning members 12 forming the first positioning space 131 extend along the second direction Y, and these two positioning members 12 have the same extension and retraction range as the two positioning members 12 forming the second positioning space 132 that extend along the second direction Y. Similarly, two of the positioning members 12 forming the third positioning space 133 extend along the second direction Y, and these two positioning members 12 have the same extension and retraction range as the two positioning members 12 forming the second positioning space 132 that extend along the second direction Y. The telescopic range of the positioning member 12 extending along the second direction Y, constituting the first positioning space 131, the second positioning space 132, and the third positioning space 133, can be specifically set according to actual needs. For example, this range can be 5m to 10m, that is, the specific length of the telescopic rod 121 at this position can be one of the following dimensions: 5m, 6m, 7m, 8m, 9m, 10m, etc. The telescopic rods 121 at the above positions have the same telescopic range, which can improve the interchangeability between the telescopic rods 121. This facilitates the assembly of the positioning device 1, thereby improving the convenience of using the positioning device 1 and thus improving the positioning efficiency of the positioning device 1.

[0043] refer to Figure 1In some embodiments of this application, optionally, the telescopic range of the positioning member 12 extending along the first direction X constituting the third positioning space 133 is different from that of the other positioning members 12, and the length of the positioning member 12 extending along the first direction X constituting the third positioning space 133 is less than that of the other positioning members 12. In other words, among the positioning members 12 forming the third positioning space 133, two positioning members 12 extend along the first direction X, and these two positioning members 12 have different telescopic ranges from the two positioning members 12 extending along the first direction X constituting the second positioning space 132 and the first positioning space 131. In the first direction X, the length of the two positioning members 12 extending along the first direction X constituting the third positioning space 133 is less than that of the other positioning members 12, and its range can specifically be 2m to 4m. In other words, the length of the two positioning members 12 extending along the first direction X constituting the third positioning space 133 can specifically be one of the dimensions such as 2m, 3m, and 4m. Since the aforementioned third tooling 23 has a relatively small size in the first direction X, the above-mentioned arrangement can reduce the volume of the third positioning space 133, making the third positioning space 133 more compatible with the third tooling 23 in terms of size. This avoids the positioning device 1 from becoming too large, saving material costs and improving its ease of use. Furthermore, it avoids errors caused by a large size difference between the third positioning space 133 and the third tooling 23, thus better ensuring the positioning accuracy of the third tooling 23.

[0044] refer to Figure 1 Optionally, the positioning mark 12a is painted on the positioning component 12. In other words, the positioning mark 12a is a symbol or pattern painted on the positioning component 12. This simplifies the structure of the positioning component 12, thereby reducing its manufacturing cost. Furthermore, after each positioning operation, the positioning component 12 can be restored by erasing the positioning mark 12a, allowing it to be reused in the installation of wind turbine units of different specifications. This improves the versatility and interchangeability of the positioning component 12, helps reduce the cost of the positioning device 1, and also enhances the ease of use of the positioning device 1.

[0045] refer to Figure 3 Specifically, the positioning process of the positioning device 1 described in this application embodiment is as follows: Feature marks 2a are made on the first tooling 21, the second tooling 22, and the third tooling 23 to align with the positioning marks on the positioning member 12 during positioning. Specifically, since the first tooling 21 is a cylindrical structure, the end of the first tooling 21 away from the second tooling 22 along the first direction X can be taken as the 0-degree point. Feature marks 2a are set at the 0-degree, 90-degree, 180-degree, and 270-degree points of the first tooling 21 along its circumference. Feature marks 2a can be symbols or patterns painted on the first tooling 21. The feature marks 2a at the 0-degree and 180-degree points of the first tooling 21 indicate the midpoint position of the first tooling 21 in the second direction Y, and the feature marks 2a at the 90-degree and 270-degree points indicate the midpoint position of the first tooling 21 in the first direction X. Feature marks 2a are set at the midpoint positions of the second tooling 22 in the first direction X and the second direction Y. The third tooling 23 has a feature mark 2a at the support point (midpoint of the bottom surface of the leg of the third tooling 23) in the first direction X, and a feature mark 2a at the midpoint in the second direction Y.

[0046] Obtain the external shape data of the first tooling 21, the second tooling 22, and the third tooling 23. Specifically, the external shape data of the first tooling 21, the second tooling 22, and the third tooling 23 can be obtained from the engineering drawings or relevant data of the high-level tooling 2 in the engine room provided by the manufacturer. Alternatively, the relevant external shape parameters of the high-level tooling 2 in the engine room can also be obtained through on-site measurement. Here, the radius of the first tooling 21 is defined as R1, the length of the second tooling 22 in the first direction X is defined as L2, and the support distance of the third tooling 23 in the first direction X is defined as L3 (L3 is specifically the distance from the midpoint of the bottom surface of the leg of the third tooling 23 along the first direction X to the edge of the third tooling 23 away from the first tooling 21).

[0047] Obtain the position data of the first tooling 21, the second tooling 22, and the third tooling 23. Specifically, the position data of the first tooling 21, the second tooling 22, and the third tooling 23 can be obtained from the engineering drawings or relevant data of the high-level tooling 2 in the engine room provided by the manufacturer. Alternatively, the relevant position parameters of the high-level tooling 2 in the engine room can also be obtained through on-site measurement. Along the first direction X, the distance between the side of the engine room away from the third tooling 23 and the 90-degree point or the 270-degree point of the first tooling 21 is S1; the distance between the side of the engine room away from the third tooling 23 and the midpoint of the second tooling 22 is S2; and the distance between the side of the engine room away from the third tooling 23 and the midpoint of the bottom surface of the leg of the third tooling 23 is S3.

[0048] Positioning fixture 21. For ease of reference, among the telescopic rods 121 forming the first positioning space 131, the two telescopic rods 121 arranged opposite each other in the second direction Y are designated as the first rod and the second rod, both extending along the first direction X. The two telescopic rods 121 arranged opposite each other in the first direction X are designated as the third rod and the fourth rod, both extending along the second direction, with the third rod being further away from the third fixture 23 in the first direction than the fourth rod. Along the second direction Y, the distance from the first rod and the second rod to the outer wall of the cabin is D. Along the first direction X, the distance from the third rod to the outer wall of the cabin is also D, and the distance from the fourth rod to the first fixture 21 is D1. Along the first direction X, the distance from the midpoint of the first rod and the midpoint of the second rod to the axis of the third rod is S1+D, and the lengths of the first rod and the second rod are both S1+D+R1+D1. The cabin has a centerline extending along the first direction X, and the cabin is symmetrical with respect to the centerline. Therefore, the lengths of the third and fourth rods in the second direction Y are both the cabin width B+2D. Along the second direction Y, the distances from the midpoint of the third rod to the axes of the first and second rods are both 0.5B+D, and the distances from the midpoint of the fourth rod to the axes of the first and second rods are both 0.5B+D. During on-site positioning, based on the above parameters, positioning marks 12a are set at the midpoints of the first, second, third, and fourth rods. The positioning mark 12a of the first rod is aligned with the feature mark 2a at the 90-degree point of the first tooling 21 along the second direction Y. The positioning mark 12a of the second rod is aligned with the feature mark 2a at the 270-degree point of the first tooling 21 along the second direction Y. The positioning mark 12a of the third rod is aligned with the feature mark 2a at the 0-degree point of the first tooling 21 along the first direction X. The positioning mark 12a of the fourth rod is aligned with the feature mark 2a at the 180-degree point of the first tooling 21 along the first direction X. This completes the positioning of the first tooling 21.

[0049] Position the second tooling 22. For ease of reference, among the telescopic rods 121 that enclose the second positioning space 132, the two telescopic rods 121 arranged opposite each other in the second direction Y are the fifth rod and the sixth rod, respectively. Both the fifth and sixth rods extend along the first direction X, with the fifth rod and the first rod arranged on the same side, and the sixth rod and the second rod arranged on the same side. The telescopic rod 121 that is spaced apart from the fourth rod in the first direction X is the seventh rod. The seventh rod extends along the second direction, and in the first direction, the seventh rod is further away from the first tooling 21 than the fourth rod. The fifth rod, the sixth rod, the seventh rod, and the aforementioned fourth rod enclose the second positioning space 132. In the first direction, the distance from the midpoint of the fifth rod and the midpoint of the sixth rod to the axis of the third rod is S2+D, and the lengths of the fifth rod and the sixth rod are S2-S1+0.5L2-R1+D2-D1, where D2 is the distance of the seventh rod along the first direction X to the second tooling 22. The cabin has a centerline extending along the first direction X, and the cabin is symmetrical with respect to the centerline. Therefore, the lengths of the seventh and fourth rods in the second direction Y are both the cabin width B+2D. Along the second direction Y, the distances from the midpoint of the seventh rod to the axis of the fifth and sixth rods are both 0.5B+D, and the distances from the midpoint of the fourth rod to the axis of the fifth and sixth rods are both 0.5B+D. During on-site positioning, based on the above parameters, positioning marks 12a are set at the midpoints of the fourth, fifth, sixth, and seventh rods. The positioning mark 12a of the fifth rod is aligned with the feature mark 2a at the midpoint of the second tooling 22 in the first direction X along the second direction Y. The positioning mark 12a of the sixth rod is aligned with the feature mark 2a at the midpoint of the second tooling 22 in the first direction X along the second direction Y. The positioning mark 12a of the seventh rod is aligned with the feature mark 2a at the midpoint of the second tooling 22 in the second direction Y along the first direction X. The positioning mark 12a of the fourth rod is aligned with the feature mark 2a at the midpoint of the second tooling 22 in the second direction Y along the first direction X. This completes the positioning of the second tooling 22.

[0050] Positioning fixture 23. For ease of reference, among the telescopic rods 121 that form the third positioning space 133, the two telescopic rods 121 arranged opposite each other in the second direction Y are designated as the eighth rod and the ninth rod. Both the eighth and ninth rods extend along the first direction X, with the eighth rod and the first rod arranged on the same side, and the ninth rod and the second rod arranged on the same side. The telescopic rod 121 that is spaced apart from the seventh rod in the first direction X is designated as the tenth rod. The tenth rod extends along the second direction, and in the first direction, the tenth rod is further away from the first fixture 21 than the seventh rod. The eighth, ninth, and tenth rods, together with the aforementioned seventh rod, form the third positioning space 133.

[0051] Positioning marks 12a are set on the eighth and ninth rods. Along the first direction X, the distance from positioning marks 12a on the eighth and ninth rods to the axis of the third rod is S3+D. The lengths of the eighth and ninth rods are S3-S2+L3-0.5L2+D3-D2, where D3 is the distance from the tenth rod along the first direction X to the third tooling 23. The cabin has a centerline extending along the first direction X, and the cabin is symmetrical with respect to the centerline. Therefore, the lengths of the tenth and seventh rods in the second direction Y are both the cabin width B+2D. Along the second direction Y, the distance from the midpoint of the tenth rod to the axis of the eighth and ninth rods is 0.5B+D, and the distance from the midpoint of the seventh rod to the axis of the eighth and ninth rods is also 0.5B+D. During on-site positioning, based on the above parameters, positioning marks 12a are set at the midpoints of the tenth and seventh rods. The positioning mark 12a of the eighth rod is aligned with the feature mark 2a of the support point of the third tooling 23 in the first direction X along the second direction Y. The positioning mark 12a of the ninth rod is aligned with the feature mark 2a of the support point of the third tooling 23 in the first direction X along the second direction Y. The positioning mark 12a of the tenth rod is aligned with the feature mark 2a of the midpoint of the third tooling 23 in the second direction Y along the first direction X. The positioning mark 12a of the seventh rod is aligned with the feature mark 2a of the midpoint of the third tooling 23 in the second direction Y along the first direction X. Thus, the positioning of the third tooling 23 is completed.

[0052] After use, the positioning device 1 can be disassembled from the positioning block 111 and the telescopic rod 121 and then folded for storage to reduce the storage space required for the positioning device 1. The distance calculation between the above points can be done manually or by computer software, which will not be elaborated here.

[0053] Secondly, embodiments of this application provide a wind turbine installation device, which includes any of the positioning devices 1 described in the first aspect and a nacelle high-position fixture 2. The nacelle high-position fixture 2 is disposed within the positioning space 13 of the positioning device 1; the nacelle high-position fixture 2 has a feature mark 2a, which is aligned with the positioning mark 12a in the positioning device 1 in the first direction X and the second direction Y. Compared with the positioning method of manual line laying, the positioning base 11 in the positioning device 1 can provide a reliable positional basis for the positioning component 12, thus eliminating the repetitive alignment process during manual line laying and helping the positioning component 12 overcome the influence of the environment on the positioning accuracy. The positioning mark 12a on the positioning component 12 can provide a reliable positioning reference for the nacelle high-position fixture 2. Compared with manual line laying, this can avoid both manual operation errors and cumulative errors, and also avoid the influence of complex working environments on positioning accuracy. Therefore, compared to the manual layout positioning method, using the positioning device 1 described in this embodiment only requires ensuring that the positioning mark 12a of the positioning component 12 is aligned with the feature mark 2a on the cabin high-level tooling 2 to achieve the positioning of the cabin high-level tooling 2. This avoids the operational and cumulative errors caused by manual layout, thus improving the positioning accuracy of the cabin high-level tooling 2. Furthermore, it simplifies the positioning process, avoiding the cumbersome steps and low positioning efficiency associated with manual layout.

[0054] The improved positioning accuracy prevents excessive positioning deviations in the nacelle high-position tooling 2, ensuring the nacelle is accurately positioned on it. This minimizes the need for readjusting the position of the high-position tooling 2, saving on hoisting equipment, reducing installation difficulties, and avoiding waste of time, manpower, and resources. In offshore operations, this ensures the wind turbine installation can proceed steadily and orderly within the hoisting window, reducing the possibility of forced interruptions and minimizing construction safety risks and operating costs.

[0055] In some embodiments of this application, optionally, the high-level tooling 2 of the nacelle includes a first tooling 21, a second tooling 22 and a third tooling 23. The first tooling 21 is adapted to support the head of the nacelle, the second tooling 22 is adapted to support the box-type transformer, and the third tooling 23 is adapted to support the tail of the nacelle.

[0056] Correspondingly, the positioning device 1 includes three positioning spaces 13, with the first tooling 21, the second tooling 22, and the third tooling 23 each located within one positioning space 13. The feature marks 2a of the first tooling 21, the second tooling 22, and the third tooling 23 are aligned with the positioning marks 12a corresponding to their respective positioning spaces 13. This allows the positioning device 1 to better correspond to the three nacelle high-level tooling 2s corresponding to the nacelle and the box-type transformer during wind turbine installation. Each of the three nacelle high-level tooling 2s can be positioned independently within its corresponding positioning space 13, avoiding mutual interference between the positioning operations of different nacelle high-level tooling 2s, thus ensuring good positioning performance for each nacelle high-level tooling 2. Simultaneously, this also improves the convenience of positioning different nacelle high-level tooling 2s, thereby increasing the positioning efficiency of the nacelle high-level tooling 2s.
