[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application 202311718176.6, filed on December 13, 2023, entitled “Nacelle, Nacelle Transport Method and Wind Turbine Generator Set,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of wind power technology, and in particular to a nacelle, a method for transporting the nacelle, and a wind turbine generator set. Background Art

[0004] At present, as the power of wind turbines gradually increases, the size of the components in the wind turbines also increases accordingly. Therefore, the size of the nacelle must also increase to ensure that the nacelle can accommodate the necessary wind turbine components.

[0005] However, due to restrictions on land transportation of units and components, such as roads, bridges, and toll booths, the design limit for engine cabin dimensions is typically 5 meters in width and 5 meters in height to avoid high transportation and modification costs. Consequently, existing engine cabins often adopt a modular design, divided into independent compartments with different functions. These compartments are then transported individually and assembled on-site to address the transportation challenges of large units. However, this design approach is prohibitively expensive and unsuitable for the current cost-conscious market environment.

[0042] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0043] The directional words appearing in the following description are all directions shown in the figures, and do not limit the cabin, the method of transporting the cabin and the wind turbine generator set of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. The term "along a certain direction" should be understood in a broad sense. For example, it can be consistent with the direction, or it can have a component in the direction, or a projection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] Please refer to Figure 1, which is a schematic structural diagram of a wind turbine generator set according to an embodiment of the present application. The present application provides a wind turbine generator set, comprising a tower 100, a nacelle 200, a generator 300, and an impeller 400. The nacelle 200 is disposed at the top of the tower 100, and the generator 300 is disposed outside the nacelle 200, but may also be located inside the nacelle 200. The impeller 400 comprises a hub 410 and a plurality of blades 420 connected to the hub 410. The impeller 400 is connected to the rotating shaft of the generator 300 via the hub 410. When wind force acts on the blades 420, it drives the entire impeller 400 and the rotating shaft of the generator 300 to rotate, thereby converting wind energy into electrical energy.

[0045] In the prior art, the wind turbine generator sets need to be transported to a predetermined location for assembly. As the units tend to be larger, the sizes of the main shaft system, gearbox, generator 300 and yaw components in the nacelle 200 are getting larger and larger, and the layout of the electrical cabinets in the nacelle 200 is limited. If the volume of the nacelle 200 is increased, high transportation and transportation modification costs will be incurred.

[0046] Therefore, in order to overcome the above-mentioned defects, the embodiment of the present application also provides a nacelle 200 and a method for transporting the nacelle 200. The nacelle 200 can be used in the wind turbine generator set of the above-mentioned embodiment and as a component of the wind turbine generator set. Of course, it can also be produced or sold separately as an independent component.

[0047] Please refer to FIG. 1 and FIG. 2 together. FIG. 2 shows a schematic structural diagram of a cabin 200 according to an embodiment of the present application.

[0048] The nacelle 200 provided in the embodiment of the present application is used to accommodate a fan component 500. The nacelle 200 includes a nacelle body 1 and a mounting platform 2. The nacelle body 1 has a receiving cavity. An opening communicating with the receiving cavity is provided on a surface of the nacelle body 1 along a first direction X. The mounting platform 2 is disposed on the nacelle body 1 and is configured to support the fan component 500. The mounting platform 2 is movable relative to the nacelle body 1 to drive at least a portion of the fan component 500 to protrude from the nacelle body 1 through the opening or to be accommodated in the receiving cavity.

[0049] According to the nacelle 200 in the embodiment of the present application, it includes a nacelle body 1 and a mounting platform 2, to which a fan component 500 can be fixed. Because the mounting platform 2 is movable relative to the nacelle body 1, during transportation of the nacelle 200, the fan component 500 can be driven by the mounting platform 2 to be stored in the accommodating cavity, thereby reducing the volume of the nacelle 200 and saving transportation costs for the nacelle 200. After the nacelle 200 is transported to a predetermined location, the fan component 500 can be driven by the mounting platform 2 to at least partially protrude from the nacelle body 1 through the opening, thereby overcoming the volume limitation of the nacelle 200 and meeting the different space requirements for transportation and operating conditions of large-scale units without using separate transportation.

[0050] Among them, the fan component 500 can be directly installed in the nacelle 200 before transportation. Since a personnel passage is often provided in the nacelle main body 1 to meet the needs of personnel going up to the tower for work and maintenance after the unit is put into operation, when the nacelle 200 is transported, the fan component 500 can be temporarily occupied by being at least partially stored in the storage cavity, thereby effectively utilizing the passage space and reducing the difficulty of transporting the nacelle 200. In addition, after the nacelle 200 is transported to the predetermined location, the fan component 500 can be at least partially protruded from the nacelle main body 1 by moving the installation platform 2, which is simple and efficient to use.

[0051] It should be noted that after the nacelle 200 is transported to the predetermined location, the fan component 500 may be arranged to protrude partially or completely from the nacelle body 1. Furthermore, depending on the installation position of the fan component 500 on the mounting platform 2, after the nacelle 200 is transported to the designated location, the mounting platform 2 may be arranged to protrude at least partially from the nacelle body 1 through an opening, or it may be located within the nacelle body 1. This is sufficient as long as the fan component 500 disposed on the mounting platform 2 can be at least partially protruded from the nacelle body 1 through the opening, thereby overcoming the volume limitation of the nacelle 200.

[0052] It can be understood that the first direction X can be the width direction of the cabin body 1. For example, an opening can be provided on the side panel 111 of the cabin body 1, which can reduce the width dimension of the cabin body 1 itself, and by making the installation platform 2 drive the fan component 500 to at least partially protrude from the opening of the side panel 111 of the cabin body 1, thereby meeting the transportation time limit width requirement of the cabin 200 and realizing an ultra-wide layout of the cabin space at a very low cost.

[0053] Alternatively, the first direction X may also be the height direction of the cabin body 1. For example, an opening may be provided on the top plate 112 or the bottom plate of the cabin body 1, thereby reducing the height dimension of the cabin body 1 itself, and by enabling the mounting platform 2 to drive the fan component 500 to at least partially protrude from the opening of the top plate 112 or the bottom plate of the cabin body 1, thereby achieving an ultra-high layout of the cabin space at an extremely low cost while meeting the height limit requirements for transporting the cabin 200.

[0054] Alternatively, the first direction X may also be the length direction of the nacelle body 1. For example, an opening may be provided on the rear end plate 113 of the nacelle body 1, which can reduce the length dimension of the nacelle body 1 itself, and by causing the installation platform 2 to drive the fan component 500 to at least partially protrude from the opening of the rear end plate 113 of the nacelle body 1, thereby reducing the difficulty of transportation conditions such as turning or changing lanes during transportation of the nacelle 200, and realizing an ultra-long layout of the nacelle space at an extremely low cost.

[0055] Optionally, the wind turbine component 500 can be configured as at least one of an electrical cabinet, a converter, and a transformer. When multiple wind turbine components 500 are provided, at least some of them can be mounted on the same mounting platform 2, allowing the multiple wind turbine components 500 to be simultaneously positioned protruding from the nacelle body 1 via the mounting platform 2. Alternatively, multiple openings can be provided in the nacelle body 1, with a mounting platform 2 positioned for each opening. This allows the wind turbine's electrical cabinet, control, hydraulic, and other components to be mounted on corresponding mounting platforms 2, thus meeting the space requirements for large-scale unit operation.

[0056] Among them, when multiple openings are set on the cabin body 1, the two side panels 111 arranged opposite to each other on the cabin body 1 are defined as the first side panel and the second side panel. The multiple openings can be set on the same one of the first side panel, the second side panel, the top panel 112, the bottom panel and the rear end panel 113 of the cabin body 1, or they can be set on at least two of the first side panel, the second side panel, the top panel 112, the bottom panel and the rear end panel 113 of the cabin body 1 respectively. The specific setting position and number of the openings can be arranged and adjusted according to the fan component 500, and can meet the space requirements of the transportation conditions and operation conditions of the large-scale unit.

[0057] For ease of description, the following embodiments and drawings are all described by taking the first direction X as the width direction of the nacelle body 1 and only one fan component 500 as an example.

[0058] In some optional embodiments, the mounting platform 2 has a first locking state and / or a second locking state. In the first locking state, the fan component 500 is at least partially received in the accommodating cavity; in the second locking state, the fan component 500 is at least partially protruding from the opening along the first direction X.

[0059] By providing the installation platform 2 with a first locking state and a second locking state, the installation platform 2 can be fixed in the first locking state during transportation to prevent the installation platform 2 from moving during transportation, and the installation platform 2 can be fixed in the second locking state during the actual operation of the wind turbine generator set to ensure the reliability of the nacelle 200 during operation.

[0060] In some optional embodiments, the mounting platform 2 moves linearly relative to the cabin body 1 through a linear guide mechanism, or the mounting platform 2 is rotationally connected to the cabin body 1 through a rotation mechanism, and the extension direction of the rotation axis of the rotation mechanism and the cabin body 1 intersects with the first direction.

[0061] In the first case, the mounting platform 2 is connected to the cabin body 1 via a linear guide mechanism. The linear guide mechanism can be configured as a slide, a rack and pinion mechanism, a screw and nut mechanism, or a telescopic rod. The linear guide mechanism can be used to drive the mounting platform 2 to translate relative to the cabin body 1, thereby changing the position of the mounting platform 2 relative to the cabin body 1 in the first direction X.

[0062] The linear guide mechanism can be specifically manually driven. For example, when the linear guide mechanism is configured as a slide groove, the slide groove can be provided on the cabin body 1, and the mounting platform 2 can be pushed manually to drive the mounting platform 2 to move linearly within the slide groove. Alternatively, the linear guide mechanism can also be electrically driven. For example, when the linear guide mechanism is a screw-nut mechanism, the cabin body 1 can be provided with a screw extending along the first direction X, and the mounting platform 2 can be threadedly engaged with the screw. Therefore, when the motor drives the screw to rotate, the mounting platform 2 can be driven to move back and forth along the first direction X to accurately control the movement distance of the mounting platform 2 relative to the cabin body 1. Alternatively, the linear guide mechanism can also be hydraulically driven. For example, when the linear guide mechanism is configured as a telescopic rod, the mounting platform 2 can be provided at the output end of the telescopic rod, so that the hydraulic cylinder drives the telescopic rod to extend and retract along the first direction X to drive the mounting platform 2 to move linearly relative to the cabin body 1.

[0063] In the second case, the mounting platform 2 is connected to the cabin body 1 through a rotating mechanism (not shown in the figure). The rotating mechanism can be specifically set as a parallelogram mechanism or a hinge mechanism. The rotating mechanism is used to drive the mounting platform 2 to rotate relative to the cabin body 1, so that the fan component 500 thereon changes its position relative to the cabin body 1 in the first direction X.

[0064] The specific structural form of the rotating mechanism can be adjusted according to the rotation direction of the rotating mechanism.

[0065] As an example, when the rotation axis of the mounting platform 2 and the nacelle body 1 extends along the second direction Y, i.e., the longitudinal direction of the nacelle body 1, the rotation mechanism can be configured as a parallelogram mechanism, so that the parallelogram mechanism drives the mounting platform 2 to rotate, thereby causing the position of the wind turbine component 500 to change relative to the nacelle body 1 in the first direction X. Furthermore, by configuring the rotation mechanism as a parallelogram mechanism, it is also possible to ensure that when the mounting platform 2 rotates, its mounting surface for supporting the wind turbine component 500 always remains horizontal, thereby achieving stable support for the wind turbine component 500.

[0066] When the mounting platform 2 and the rotation axis of the cabin body 1 are extended along the third direction Z, that is, the height direction of the cabin body 1, the rotating mechanism can be set as a hinge mechanism, and the mounting platform 2 may include a first connecting plate and a second connecting plate arranged to intersect, the first connecting plate being rotatably connected to the main frame 12, and the second connecting plate forming a horizontal mounting surface for fixing the fan component 500, so that the fan component 500 can be rotated relative to the main frame 12 by the first connecting plate, so that the position of the fan component 500 relative to the cabin body 1 in the first direction X can be changed.

[0067] Please refer to Figures 2 to 4. Considering that the wind turbine component 500 has a certain weight, the mounting platform 2 needs to have sufficient load-bearing capacity. In some optional embodiments, the nacelle body 1 includes a shell 11 and a main frame 12. The shell 11 encloses a receiving cavity with an opening. The main frame 12 is arranged in the receiving cavity, and the mounting platform 2 is arranged on the main frame 12. The mounting platform 2 can change its position relative to the main frame 12 in the first direction X.

[0068] Since the main frame 12 is the foundation of the cabin body 1, that is, the fan component 500 can be fixed on the mounting platform 2, and by installing the mounting platform 2 on the main frame 12 of the cabin body 1, the main frame 12 can bear the weight of equipment such as the fan component 500 and the vibration during operation, thereby achieving stable bearing of the fan component 500 and making the overall structure more reliable.

[0069] To enable the mounting platform 2 to change position relative to the main frame 12 in the first direction X, in some optional embodiments, the main frame 12 is provided with a slide groove 121 extending along the first direction X. The mounting platform 2 is slidably connected to the slide groove 121. That is, the mounting platform 2 can be translated relative to the main frame 12 via the slide groove 121 to move the fan component 500 disposed on the mounting platform 2 out of the accommodating cavity. The use of a sliding structure to move the mounting platform 2 simplifies the structure, facilitates on-site assembly and disassembly, reduces installation time and costs, and provides high reliability.

[0070] Optionally, the slide groove 121 may be configured as a V-shaped groove or a dovetail groove, and the mounting platform 2 may be provided with a protrusion matching the slide groove 121 , so that the mounting platform 2 can be arranged to translate relative to the main frame 12 .

[0071] Referring to Figures 3 to 6, in some optional embodiments, the slide 121 includes a sliding section 1211 and a first limiting section 1212 and a second limiting section 1213, respectively disposed at opposite ends of the sliding section 1211 along the first direction X. The first limiting section 1212 is located on a side closer to the opening than the second limiting section 1213. The mounting platform 2 has a first locked state and a second locked state. In the first locked state, the mounting platform 2 is secured to the second limiting section 1213, and the fan component 500 is at least partially accommodated within the accommodating cavity. In the second locked state, the mounting platform 2 is secured to the first limiting section 1212, and the fan component 500 is at least partially protruded from the opening along the first direction X.

[0072] 3 and 4 are schematic diagrams of the structure of the mounting platform 2 in the first locking state, and FIG. 5 and 6 are schematic diagrams of the structure of the mounting platform 2 in the second locking state.

[0073] By setting the first limit section 1212 and the second limit section 1213 at both ends of the slide groove 121, it can ensure that the two extreme positions of the installation platform 2 within the sliding range can be effectively fixed and constrained, avoiding the installation platform 2 from sliding during transportation, increasing the stability of the structure, and being safer and more reliable.

[0074] In some optional embodiments, a first limiting hole K1 and a second limiting hole K2 are spaced apart on the mounting platform 2 along the first direction X, and the first limiting hole K1 is located at the protruding end of the mounting platform 2. The mounting platform 2 also includes a limiting member 3, which is detachably connected to the first limiting hole K1 or the second limiting hole K2 to enable the mounting platform 2 to switch between the first locking state and the second locking state.

[0075] In addition, by opening a limit hole and setting a limit member 3 passing through the limit hole and the slide groove 121, it is ensured that the installation platform 2 can only move along the first direction X and can be fastened at the limit section position, thereby ensuring the safety of the installation platform 2 during movement and the reliability during fastening.

[0076] It is understood that the limiting member 3 can be configured as a pin assembly. Therefore, when the mounting platform 2 switches from the first locking state to the second locking state, the limiting member 3 can be loosened without being removed, so that the limiting member 3 can be used as a slide bar. By moving the limiting member 3 along the sliding section 1211, the stability of the mounting platform 2 along the main frame 12 is improved. When the mounting platform 2 moves to the extreme position, the limiting member 3 is locked to the first limiting section 1212 or the second limiting section 1213 to lock the mounting platform 2 in the first locking state or the second locking state.

[0077] Furthermore, in the first locking state, the first limiting hole K1 is aligned with the second limiting section 1213, the limiting member 3 passes through the first limiting hole K1, and the mounting platform 2 is locked in the second limiting section 1213. In the second locking state, the second limiting hole K2 is aligned with the first limiting section 1212, the limiting member 3 passes through the second limiting hole K2, and the mounting platform 2 is locked in the first limiting section 1212.

[0078] The above-mentioned setting method can reduce the size of the main bracket, which is the slide groove 121, when the removal size of the installation platform 2 is fixed, or increase the movable distance of the installation platform 2 under the condition that the length of the slide groove 121 is limited, thereby increasing the protruding distance of the installation platform 2 relative to the accommodating cavity along the first direction X in the second locking state, so as to increase the expandable space of the cabin 200.

[0079] Please refer to Figures 7 to 9. In some optional embodiments, a support hole K3 is further provided on the main frame 12, and the cabin 200 also includes a support member 4. In the second locking state, both ends of the support member 4 are respectively connected to the first limit hole K1 and the support hole K3.

[0080] Since the support member 4 is at least partially protruding from the main frame 12 along the first direction X in the second locking state, the support member 4 is provided to support the outer edge of the mounting platform 2. The support member 4 can bear the load of the portion of the mounting platform 2 that protrudes out of the main bracket, thereby enhancing the stability of the structure.

[0081] It can be understood that the support member 4 is an inclined support, and its shape and size can be calculated and determined based on the weight of the fan component 500 to be installed on the installation platform 2, so as to ensure that the installation platform 2 can reliably support the fan component 500 in the second locking state.

[0082] Referring to Figures 3 to 7 , in some optional embodiments, a side of the main frame 12 near the opening is provided with a pair of support ribs 122 along the second direction Y, and a slide groove 121 is provided on the support ribs 122. The mounting platform 2 includes a main body 21 and side portions 22 connected to both ends of the main body 21 along the second direction Y. The side portions 22 are provided on either side of the paired support ribs 122 and are slidably connected to the support ribs 122 via the slide groove 121. The second direction Y intersects with the first direction X.

[0083] By providing a support rib 122 on one side of the main frame 12 near the opening and providing a slide groove 121 on the support rib 122 to allow the mounting platform 2 to slide along the slide groove 121, the structure is simplified, facilitating processing and installation. The paired support ribs 122 and side portions 22 optimize structural stress and ensure the stability of the support provided by the support ribs 122 to the mounting platform 2. The mounting platform 2 is clipped onto the support rib 122 via the side portions 22, further limiting the mounting platform 2's degrees of freedom in other directions and ensuring smoother movement of the mounting platform 2 along the first direction X.

[0084] Optionally, a bending portion 1221 may be provided at one end of the support rib 122 along the third direction Z toward the main body 21 to increase the rigidity of the support rib 122 through the bending portion 1221, so that the support rib 122 can support the mounting platform 2 more stably.

[0085] Please refer to Figures 8 and 9. In some optional embodiments, in the third direction Z, the first limiting section 1212 and the second limiting section 1213 are protruded relative to the sliding section 1211 toward a side away from the mounting platform 2, and the third direction Z, the first direction X and the second direction Y intersect with each other.

[0086] That is, the height of the first limit section 1212 and the second limit section 1213 is lower than the height of the sliding section 1211, so that when the mounting platform 2 moves to the two extreme positions, it can drive the limit member 3 downward to be clamped into the first limit section 1212 and the second limit section 1213 by its own gravity, further structurally ensuring the reliability of the fastening connection of the mounting platform 2 at the extreme positions.

[0087] Since the heights of the first limiting section 1212 and the second limiting section 1213 are different from the heights of the sliding section 1211, in order to facilitate the sliding of the installation platform 2 along the first direction X, in some optional embodiments, an arc-shaped transition is set between the first limiting section 1212 and the second limiting section 1213 and the sliding section 1211.

[0088] On the one hand, this ensures the stability of the mounting platform 2 during its sliding process, preventing the mounting platform 2 from suddenly falling when it reaches its limit position, thereby causing damage to the fan component 500. On the other hand, it also reduces the resistance of the limiting member 3 when it slides out of the first limiting section 1212 and the second limiting section 1213, thereby facilitating the switching of the mounting platform 2 between the first locked state and the second locked state.

[0089] Referring to Figure 10 , in some optional embodiments, nacelle 200 further includes a cover plate 5 having a central region and an edge region. The central region protrudes relative to the edge region along a first direction X. The edge region of the cover plate 5 is connected to a surface of the nacelle body 1 facing away from the accommodating cavity and engages with the opening. The cover plate 5 can be positioned to cover the opening of nacelle 200 and enclose the fan component 500 protruding from the accommodating cavity, thereby sealing the interior of nacelle 200 and improving the reliability of the fan component 500.

[0090] During transportation, the cover plate 5 can be placed in the accommodating cavity as a random accessory. After the cabin 200 is transported to the site, the cover plate 5 can be taken out of the accommodating cavity and fastened on the opening of the cabin 200 to seal it.

[0091] Referring to FIG. 1 to FIG. 11 , an embodiment of the present application further provides a method for transporting a cabin 200 , including:

[0092] S1, providing the nacelle 200 of the above embodiment, with a fan component 500 mounted on the mounting platform 2, controlling the movement of the mounting platform 2 to at least partially accommodate the fan component 500 in the accommodating cavity;

[0093] S2, moving the nacelle 200 to a designated location by means of a transportation vehicle, and controlling the movement of the installation platform 2 so that the wind turbine component 500 is at least partially protruded from the nacelle body 1 through the opening.

[0094] The method for transporting nacelle 200 in the embodiment of the present application reduces the volume of nacelle 200 and saves transportation costs by storing fan components 500 in the accommodating chamber during transportation. For example, a personnel passage within the accommodating chamber can be initially occupied. After transport to the designated location, fan components 500 are positioned to protrude from nacelle body 1 through the opening, thereby overcoming the volume limitations of nacelle 200 and meeting the varying space requirements for transportation and operating conditions of large-scale units at a very low cost.

[0095] It is understandable that the means of transport may be a vehicle, a ship or other vehicles.

[0096] The following takes the structure of the nacelle 200 in one embodiment as an example to illustrate the working principle of switching the fan component 500 from being stored in the accommodating cavity to being protruding from the accommodating cavity in the embodiment of the present application.

[0097] Since the fan component 500 is at least partially stored in the accommodating cavity during transportation, the mounting platform 2 is in the first locking state, the first limiting hole K1 of the mounting platform 2 is relative to the second limiting section 1213 of the slide groove 121, and the limiting member 3 is provided through the first limiting hole K1 and the second limiting section 1213.

[0098] Therefore, after transporting to the predetermined position, the limiting member 3 can be loosened first, and then the installation platform 2 or the fan component 500 can be manually pushed to slide the installation platform 2 along the slide groove 121 toward the opening until the first limiting hole K1 of the installation platform 2 is aligned with the first limiting section 1212 of the slide groove 121. Next, the limiting member 3 can be removed, and the installation platform 2 can be pushed further to slide the installation platform 2 along the slide groove 121 toward the opening until the second limiting hole K2 of the installation platform 2 is aligned with the first limiting section 1212 of the slide groove 121. Then, the limiting member 3 is inserted through the second limiting hole K2 and the first limiting section 1212 to switch the installation platform 2 to the second locked state, so that the fan component 500 at least partially protrudes from the accommodating cavity.

[0099] Among them, after the second limiting hole K2 of the mounting platform 2 is aligned with the first limiting section 1212 of the slide groove 121, the outer edge of the mounting platform 2 can be supported by the support member 4, and then the limiting member 3 is passed through the second limiting hole K2 and the first limiting section 1212 to achieve reliable support of the fan component 500 by the mounting platform 2 in the second locking state.

[0100] In some optional embodiments, the cabin 200 further includes a cover plate 5. After the step of moving the cabin 200 to a designated location by a transportation vehicle, the following steps are further included:

[0101] The cover plate 5 is buckled onto the opening of the cabin body 1 to seal the accommodating cavity.

[0102] Therefore, after switching the mounting platform 2 to the second locking state, the cover plate 5 can also be closed on the open side of the cabin 200 and cover the fan component 500 protruding from the accommodating cavity to seal the internal space of the cabin 200 and improve the reliability of the fan component 500.

[0103] The wind turbine generator set according to the embodiment of the present application includes the nacelle 200 according to the above embodiment, so it has the advantages of low transportation cost and large built-in space of the nacelle 200, and is easier to promote and use.

[0104] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
