Description

Technical Field

[0001] This application relates to the field of wind power generation technology, and in particular to a combined nacelle and wind turbine generator set. Background Technology

[0002] With the development of wind power technology, the capacity of wind turbine generators used on land has gradually increased. To ensure the normal operation of these large-capacity wind turbine generators, they typically require larger yaw drive motors and matching bases, as well as larger nacelles. Furthermore, to obtain sufficient wind power, the locations where wind turbine generators are installed are usually quite remote, requiring the components to be transported separately to the installation site for assembly. During this process, the large nacelles require higher transportation standards, resulting in a decrease in overall transportation efficiency and higher transportation costs.

[0003] Therefore, there is an urgent need for a nacelle that can be adapted to large-capacity units and is easy to transport, as well as a corresponding wind turbine generator set. Summary of the Invention

[0036] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, "multiple" means two or more, and the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections. The terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate orientation or positional relationships only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art will understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] In the existing field of wind power technology, with the innovation and progress of wind power technology and related material technology, the capacity of wind turbine generators has gradually increased. At present, the single unit capacity of onshore wind turbine generators can even reach 8MW. Larger capacity wind turbine generators usually require larger nacelle bases and yaw drives, which in turn require larger nacelles. Therefore, the nacelle size in existing wind turbine generators has also increased.

[0040] Meanwhile, to ensure sufficient wind power, onshore wind turbines are typically installed in remote locations. Components within the turbine usually need to be transported separately to the installation site for assembly. During this process, the nacelle base, due to its large size, can pose a transportation challenge. Existing nacelle bases are usually integrally machined castings, thus requiring transport as a whole. When transporting large items on land, items with a width between 3.5m and 4.5m are classified as Class I large items, while those between 4.5m and 5.5m are Class II large items. The required vehicles, transportation routes, and technical personnel differ accordingly based on the classification.

[0041] Based on this, the inventors discovered that as the capacity of wind turbine generator sets gradually increases, the size of the base also gradually increases. When transporting the nacelle or base, higher transportation specifications are usually required, which results in problems such as low transportation efficiency and high transportation costs.

[0042] To address the aforementioned issues, this application proposes a modular cabin, in which the cabin is configured as multiple detachable and connectable modules. By rationally dividing the cabin into multiple modules for separate transportation, transportation efficiency can be effectively improved and transportation costs reduced.

[0043] It is understood that the following embodiments of this application are only described by way of example, which include at least a base, a main beam and a support frame in the nacelle. However, it should be understood that this application is not limited to this and may also include embodiments with other components used in the nacelle of wind turbine generators, and protect such embodiments.

[0044] To better understand this application, the following will be combined with... Figures 1 to 7 The combined nacelle and wind turbine generator set of the embodiments of this application will be described in detail.

[0045] Please refer to the following: Figures 1 to 5 , Figure 1 This is a structural schematic diagram of a modular cabin provided in an embodiment of this application. Figure 2 This is an exploded structural diagram of the combined cabin provided in the embodiments of this application. Figure 3 This is a top view of the combined cabin provided in the embodiments of this application. Figure 4 This is a partial structural schematic diagram of the combined cabin provided in an embodiment of this application. Figure 5 This is a schematic diagram of the structure of the seat unit provided in the embodiment of this application.

[0046] In a first aspect, according to embodiments of this application, a modular cabin 100 is provided, comprising: a base portion 10 and a support frame 20, wherein the base portion 10 includes at least two seat units 11 and a main beam 12 corresponding to at least one seat unit 11, wherein adjacent two seat units 11 are detachably connected to each other. The support frame 20 has a receiving cavity 21, the base portion 10 is at least partially located in the receiving cavity 21, the support frame 20 is detachably connected to the base portion 10, and the support frame 20 includes two or more frame units 22, adjacent frame units 22 are detachably connected to each other, and each frame unit 22 is detachably connected to at least one seat unit 11.

[0047] The combined cabin 100 in this embodiment includes a base portion 10 and a support frame 20. Both the base portion 10 and the support frame 20 include multiple detachably connected components. The base portion 10 includes multiple detachably connected seat units 11 and a main beam 12 connected to the seat units 11. The multiple seat units 11 can be connected end-to-end in sequence and are detachably connected to form a complete base. In this embodiment, the base portion 10 includes at least two seat units 11. When the complete base is divided into multiple seat units 11, the interface can be planar or curved. The resulting multiple seat units 11 can be symmetrically or irregularly distributed, as long as a stable and reliable detachable connection can be formed between adjacent seat units 11.

[0048] Taking the base portion 10 to be formed having a circular through hole for accommodating other components as an example, in order to facilitate processing, casting, and transportation, the multiple base units 11 in this embodiment can be divided according to similar volumes. For example, when two base units 11 are included, the interface between the two base units 11 can be a symmetrical plane extending in the same direction along the extension direction of the base portion 10 itself, so that the base portion 10 is divided into two symmetrical base units 11. Alternatively, when three or four base units 11 are included, the hole wall portion can be divided into three equal parts with a central angle of 120° or a central angle of 90°, with the center of the circular through hole as the center. During transportation, these base units 11 are transported separately, thereby reducing the level of transportation required and reducing transportation costs. When in use, these multiple base units 11 are connected end to end to form a complete base portion 10 for easy use.

[0049] The base portion 10 in this embodiment further includes main beams 12, each of which is connected to a seat unit 11. Optionally, each seat unit 11 may have one main beam 12 connected to it, or multiple main beams 12 may be connected simultaneously. Alternatively, all main beams 12 may be interconnected with the same seat unit 11. The distribution can be based on the division method of the seat units 11 and the volume of each seat unit 11. The main beams 12 can be connected to the seat units 11 using detachable or fixed connections. Multiple main beams 12 can be arranged in parallel or extend along intersecting directions.

[0050] Optionally, the extension direction and extension dimension of the main beam 12, as well as the relative positional relationship between the main beam 12 and the seat unit 11, can be designed according to the overall shape and volume required by the combined cabin 100. After the seat unit 11 and the main beam 12 are set up, the base part 10 can be used as the base or frame for the subsequent installation and configuration of other components. That is, the combined cabin 100 in this application can adjust its shape and size by adjusting the position and size of each component in the base part 10.

[0051] The modular cabin 100 in this embodiment further includes a support frame 20, which forms part of the skeleton structure of the modular cabin 100 except for the base portion 10, and at least partially houses the base portion 10 within the receiving cavity 21 formed by the support frame 20. After the support frame 20 is installed, other components such as a cabin cover can be installed on the support frame 20 according to the specific design and usage requirements of the cabin.

[0052] The support frame 20 in this embodiment includes at least two frame units 22 that are detachably connected to each other. Similar to the arrangement of the seat unit 11, these frame units 22 can be detachably connected to the seat unit 11, or detachably connected to both the seat unit 11 and the main beam 12. The structures of the multiple frame units 22 can be the same or different. At the same time, the method of dividing the overall structure of the frame units 22 can be the same as the method of dividing the seat unit 11 and the main beam 12, that is, the interface between adjacent frame units 22 can coincide with the interface between the seat unit 11 or the main beam 12, thereby enabling the combined cabin 100 to be divided into multiple parts for transportation in a more regular manner.

[0053] Optionally, the support frame 20 in this embodiment can also be divided according to its own shape and position. That is, in addition to being divided into multiple frame units 22 corresponding to the seat unit 11, the support frame 20 can also be divided into multiple frame units 22 according to each surface of the rectangle, and processed and transported separately, and then assembled after being transported to the assembly site.

[0054] It is understood that the modular cabin 100 in this embodiment includes a base portion 10 and a support frame 20. The base portion 10 further includes a seat unit 11 and a main beam 12. The seat unit 11 and the main beam 12 can be fixedly connected or detachably connected. The support frame 20 and the base portion 10 are detachably connected. That is, when transporting the modular cabin 100, the base portion 10 and the support frame 20 can be transported separately. Alternatively, the seat unit 11 and the frame unit 22 connected to the seat unit 11 can be transported together. Alternatively, the interconnected seat unit 11, main beam 12, and frame unit 22 can be transported together. That is, the modular cabin 100 includes multiple separately transportable structural parts, each part including at least one of the seat unit 11, main beam 12, and frame unit 22. Given that most of the components in the modular cabin 100 are detachably connected, they can be disassembled and transported according to the specific component dimensions and division methods. This application does not impose specific limitations on this.

[0055] In some alternative embodiments, the base portion 10 includes two seat units 11, which are disposed opposite to each other in a first direction X and are detachably connected. Each seat unit 11 is connected to a main beam 12, and each main beam 12 extends along a second direction Y, where the first direction X intersects with the second direction Y.

[0056] This application provides a modular nacelle 100, in which multiple seat units 11 are spliced ​​together to form a complete base portion 10. During the use of wind turbine generator sets, the base portion 10 usually needs to withstand large impacts and loads, so there are certain requirements for the overall strength of the base portion 10. Based on this, in order to ensure that the base portion 10 has corresponding connection strength and impact resistance, and to avoid misalignment or separation at the connection points during use, the base portion 10 can be split into two seat units 11. The two seat units 11 can be arranged opposite each other in the first direction X and can be detachably connected. Each seat unit 11 can be connected to at least one main beam 12. These main beams 12 can extend along the second direction Y intersecting the first direction X, that is, the modular nacelle 100 can be divided into two parts along the direction intersecting the main extension direction of the base portion 10, so as to reduce the width of the base portion 10 to a greater extent and facilitate the transportation of the modular nacelle 100.

[0057] In some alternative embodiments, the two seat units 11 have the same structure and are symmetrically distributed in the first direction X.

[0058] As mentioned above, the base portion 10 may include two seat units 11, and these two seat units 11 may be symmetrically arranged in the first direction X. That is, the seat units 11 may be divided with a certain symmetrical plane of the base portion 10 as the dividing interface, thereby forming seat units 11 with symmetrical identical structures, so as to more evenly and stably bear the load, and the symmetrical division also facilitates the design and processing of the seat units 11.

[0059] It is understandable that, based on the symmetrical arrangement of the two seat units 11, the main beam 12 connected to the seat units 11 can also be symmetrically arranged. Furthermore, the frame unit 22 connected to the seat units 11 can also be symmetrically arranged. Based on the symmetrical arrangement of all three, the combined cabin 100 can be divided into two symmetrical parts, so that the overall structure is convenient for both transportation and loading and unloading.

[0060] Optionally, the first direction X can be perpendicular to the second direction Y to form a more regular and easier-to-manufacture interface, and to reduce the width dimensions of the two parts of the combined cabin 100 to a large extent.

[0061] Please see Figure 6 , Figure 6 This is a partial structural schematic diagram of the seat unit provided in the embodiments of this application. In some optional embodiments, two seat units 11 spliced ​​together are provided with connecting flanges 111 at the splicing point. One connecting flange 111 is provided with a positioning pin 112 and the other connecting flange 111 is provided with a positioning hole 113. The positioning pin 112 and the positioning hole 113 are matched in shape and can be inserted and engaged.

[0062] Optionally, in this embodiment, a connecting flange 111 may be provided between two adjacent seat units 11. The interface between the connecting flange 111 and the seat unit 11 is arranged parallel to each other, so that the connecting flanges 111 of adjacent seat units 11 can fit together smoothly and abut against each other, forming a stable connection. Based on the provision of connecting flanges 111, adjacent connecting flanges 111 can be aligned and fixed together by the cooperation of positioning pins 112 and positioning holes 113.

[0063] By inserting the positioning pin 112 on one side of the connecting flange 111 into the positioning hole 113 on the other side of the connecting flange 111, the two connected seat units 11 can be precisely aligned, ensuring that the circular through hole formed by the two seat units 11 in the base part 10 has a certain coaxiality and preventing misalignment.

[0064] It is understood that in the embodiments of this application, the positioning pins 112 provided at each connection between adjacent seat units 11 can be respectively provided on the connecting flanges 111 on both sides. Correspondingly, the positioning holes 113 can also be respectively provided on the connecting flanges 111 on both sides. That is, each connecting flange 111 can be provided with both positioning pins 112 and positioning holes 113 at the same time. As long as the connecting flanges 111 on both sides to be connected can be aligned and inserted, the connection can be made more stable and the load-bearing capacity at the connection can be more uniform.

[0065] In some alternative embodiments, the end of the locating pin 112 opposite to the connected seat unit 11 is tapered.

[0066] In this embodiment, the positioning pin 112 can be provided starting from the connecting surface of the connecting flange 111 and extending towards the opposite connecting flange 111. On this basis, the end of the positioning pin 112 away from the seat unit 11 to which it is connected can be provided with a tapered end. That is, the protruding end of the cylindrical pin can be processed into a tapered end to achieve a guiding function. When an alignment error occurs between the two connected seat units 11, it can be guided by the inclined surface of the tapered end, so that the positioning pin 112 can slide into the corresponding positioning hole 113 along the inclined angle of the inclined surface, which has a certain error elimination capability.

[0067] In some alternative embodiments, the locating pin is provided with a force-applying part, which includes at least one flat surface disposed on the outer peripheral wall of the locating pin 112. A threaded connection can be formed between the locating pin 112 and the locating hole 113. Based on this, it is usually necessary to rotate the locating pin 112 circumferentially. To facilitate the application of a driving force for rotation, a force-applying part can be provided on the outer peripheral wall of the locating pin 112. The force-applying part includes at least one flat surface parallel to the axial direction of the locating pin 112. When the locating pin 112 is rotated, it can be held and fixed by the force-applying part, and the clamping surface of the clamp abuts against the flat surface to avoid slippage or other problems when rotating the cylindrical pin.

[0068] It is understood that the force-applying part may include a plane, or the force-applying part may include two planes arranged symmetrically and in parallel, in order to further increase the force-applying area between the clamping member and the positioning pin 112, so as to facilitate the rotation of the positioning pin 112.

[0069] In some alternative embodiments, in the two seat units 11 that are spliced ​​together, one of them is provided with a protrusion and the other is provided with a recess of a matching shape, and the protrusion can be inserted into the recess to connect and fix the two seat units 11.

[0070] Corresponding to the connection method of the connecting flange 111, the locating pin 112, and the locating hole 113, the seat units 11 can be detachably connected by using a connection method with protrusions and recesses. In this connection method, the protrusions and recesses can extend correspondingly along the second direction Y. In embodiments where the seat units 11 are symmetrically arranged along the first direction X, the protrusions extending along the intersecting second direction Y can effectively prevent the connection between the seat units 11 from slipping.

[0071] It is understood that a protrusion and a recess can be provided at each connection between adjacent seat units 11, or multiple protrusions and recesses can be provided at intervals. In this case, protrusions and recesses can be provided simultaneously on the seat unit 11 on the same side, and the protrusions and recesses can be provided alternately at equal intervals to form a stable and firm connection.

[0072] In addition, the seat unit 11 in this embodiment can also be connected and fixed by a positioning pin arranged in a direction perpendicular to the plane formed by the first direction X and the second direction Y. At this time, a connecting hole can be provided between adjacent seat units 11 that runs through and overlaps each other in the aforementioned direction, so that the positioning pin passes through the connecting hole provided on both sides of the seat unit 11 at the same time, thereby forming a corresponding connection and fixation.

[0073] In some alternative embodiments, each seat unit 11 includes an interconnected bottom flange 114 and an annular sidewall 115, at least one of the bottom flange 114 and the annular sidewall 115 being detachably connected to a support frame 20.

[0074] The seat unit 11 in this embodiment may include a bottom flange 114 and an annular sidewall 115. Multiple annular sidewalls 115 of connected seat units 11 are interconnected to form the aforementioned circular through hole. The bottom flange 114 may extend along a plane perpendicular to the axial direction of the annular sidewall 115 to facilitate the assembly and fixation of the combined nacelle 100 with other components such as the tower. Multiple through holes may be spaced apart on the bottom flange 114 to facilitate connection with other components.

[0075] It is understood that the base portion 10 in this embodiment includes a seat unit 11 and a main beam 12, wherein the bottom flange 114 can be appropriately avoided at the connection position between the seat unit 11 and the main beam 12. Meanwhile, the sidewall height and sidewall thickness of the annular sidewall 115 can be adjusted and designed according to the requirements for cooperation with other components, and this application does not impose specific limitations on them.

[0076] In this embodiment, the frame unit 22 and the same seat unit 11 may have multiple connection points. Based on this, the frame unit 22 may be connected to either the bottom flange 114 or the annular sidewall 115. Alternatively, the frame unit 22 may be connected to both the bottom flange 114 and the annular sidewall 115. This connection may be detachable so that the support frame 20 and the base part 10 can be transported separately according to actual needs.

[0077] In some alternative embodiments, each seat unit 11 is provided with a cantilever beam, and the seat unit 11 is detachably connected to the support frame 20 via the cantilever beam.

[0078] As mentioned above, when the support frame 20 is connected to the seat unit 11, it can be connected to the bottom flange 114 and / or the annular sidewall 115. Due to the limitation of the extension direction of the support frame 20 itself, the part of the support frame 20 connected to the bottom flange 114 can be directly connected to the side surface of the bottom flange 114 near the annular sidewall 115, while the part of the support frame 115 connected to the annular sidewall 115 can be connected by a cantilever beam, that is, a cantilever beam extending along the second direction Y is provided on the outer side wall of the annular sidewall 115, and the support frame 20 is connected to the protruding end of the cantilever beam.

[0079] It is understandable that the support frame 20 connected to the annular sidewall 115 can also be directly connected, that is, one side surface of the support frame 20 can be connected to the outer surface of the annular sidewall 115 by means of screws, rivets or other connection methods; correspondingly, the part of the support frame 20 connected to the bottom flange 114 can also be connected by a cantilever beam, thereby expanding the volume of the internal cavity 21 of the support frame 20, and correspondingly expanding the overall volume of the combined cabin 100. The specific expansion can be adjusted by the length of the cantilever beam.

[0080] Optionally, the connection between the support frame 20 and the main beam 12 in this embodiment can also be achieved by a cantilever beam, that is, a cantilever beam extending protruding along the first direction X is provided on the surface of the main beam 12, and the protruding end is connected to the support frame 20.

[0081] In summary, the present application does not impose specific limitations on the connection method between the support frame 20 and the seat unit 11, and the connection methods in the above embodiments can be selected and matched.

[0082] In some optional embodiments, the number of frame units 22 is the same as the number of seat units 11, and the frame units 22 and seat units 11 are arranged in a one-to-one correspondence.

[0083] In this embodiment, the support frame 20 can be divided into frame units 22, which are the same number as the seat units 11. That is, each seat unit 11 is connected to a frame unit 22, and the two are set one-to-one. This allows the seat units 11 and frame units 22 to be preliminarily aligned and assembled on the processing site with the help of sufficient mechanical equipment after processing and production, forming multiple independent and detachably connected cabin components. This facilitates the segmented transportation of the modular cabin 100 and saves the assembly operation required after transportation to the installation site, thereby improving assembly efficiency.

[0084] In some optional embodiments, there are two seat units 11 and two frame units 22. The two seat units 11 are symmetrically distributed with respect to the first reference surface, and the two frame units 22 are symmetrically distributed with respect to the second reference surface. The first reference surface and the second reference surface coincide.

[0085] In this embodiment, the seat unit 11 and the frame unit 22 are arranged in a one-to-one correspondence. The two can be arranged symmetrically with the same plane as the plane. On this basis, the main beam 12 is also arranged symmetrically with respect to the same plane, so that the combined cabin 100 can be divided into two completely symmetrical parts. The two parts are detachably connected. In this connection relationship, the seat unit 11 and the support frame 20 in the two parts can be detachably connected to form a firm and reliable connection relationship.

[0086] In some alternative embodiments, there are two main beams 12, which are arranged in a one-to-one correspondence with two seat units 11, and each frame unit 22 is connected to both the seat unit 11 and the main beam 12.

[0087] In this embodiment, the number of main beams 12 can be the same as the number of seat units 11, and they can be arranged in a one-to-one correspondence. As mentioned above, the combined cabin 100 can then form two symmetrical and detachably connected parts. Simultaneously, the frame unit 22 can be connected to both the seat unit 11 and the main beam 12, provided that the seat unit 11 and the main beam 12 are already connected and fixed. In this case, the frame unit 22 can provide support while also providing auxiliary connection and fixation for the connection between the seat unit 11 and the main beam 12.

[0088] like Figure 2 As shown, in some optional embodiments, the support frame 20 is an overall frame structure. The support frame 20 has a main frame 23, a plurality of support frames 24 and a plurality of diagonal supports 25. The main frame 23 is spaced apart from the base portion 10. One end of each support frame 24 is connected to the main frame 23 and the other end is connected to one of the seat unit 11 and the main beam 12. Each diagonal support 25 is intersected with the support frame 24 and connected between the main frame 23 and the support frame 24.

[0089] The support frame 20 in this embodiment can be a frame structure for forming the receiving cavity 21, which may include a main frame 23 extending in the same direction as the main beam 12, a support frame 24 perpendicular to the bottom flange 114, and an oblique support 25 inclinedly connected between the two, forming a rectangular frame structure with oblique reinforcement.

[0090] The support frame 20 in this embodiment can be used to accommodate the base portion 10 and other mechanical components that need to be installed in the cabin. It can also be used as a skeleton for installing the cabin cover. Setting the support frame 20 as a rectangular frame with diagonal bracing reinforcement can give the support frame 20 corresponding support strength. At the same time, connecting the support frame 20 to the base portion 10 through multiple connection points can further improve the strength of the support frame 20.

[0091] In some alternative embodiments, the support frame 20 further includes an auxiliary support 26 connected between adjacent main beams 12 and extending in a direction perpendicular to the main beams 12.

[0092] To further reinforce the support structure of the modular cabin 100, the support frame 20 may also include auxiliary supports 26. The auxiliary supports 26 are disposed between adjacent main beams 12. When multiple main beams 12 extend in the same direction, the auxiliary supports 26 can be disposed perpendicular to the main beams 12 to provide good support and fixation. When multiple main beams 12 extend in multiple intersecting directions, the auxiliary supports 26 between adjacent main beams 12 can extend along a broken line, that is, the two auxiliary supports 26 are perpendicular to the main beams 12 on both sides respectively. Alternatively, the auxiliary supports 26 can still extend along a straight line and form a certain angle with the main beams 12. As long as the auxiliary supports 26 can help fix the distance between adjacent main beams 12 to a preset value.

[0093] It is understood that the auxiliary support 26 can be a single frame structure, a multi-parallel frame structure, or a reinforced frame structure, such as an I-beam frame, etc. This application does not make any specific limitations in this regard.

[0094] In some alternative embodiments, the main beam 12 and the seat unit 11 are detachably connected; or, the main beam 12 and the connected seat unit 11 are an integral structure.

[0095] In this embodiment, the main beam 12 and the seat unit 11 connected thereto can be integrally formed. That is, when casting the seat unit 11, the main beam 12 can be cast integrally at the same time, thereby obtaining a base part 10 with high strength. Alternatively, in this embodiment, the main beam 12 and the seat unit 11 can be detachably connected, thereby saving materials. Optionally, the seat unit 11 and the main beam 12 can also be connected and fixed by flanges and hole and pin fits or screw and nut fits. The specific connection method can be designed according to the strength requirements.
