Description

[0002] At present, as the power of wind turbine generator sets gradually increases, the sizes of various components inside the wind turbine generator sets also increase accordingly. Therefore, the size of the nacelle must also increase to ensure that the nacelle can accommodate the necessary fan components.

Therefore, existing nacelles often adopt modular design, divided into independent compartments with different functions, and use the method of separate transportation and on-site assembly to solve the problem of transporting large units.

[0038] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale. Detailed implementation manners

[0039] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessarily obscuring the present application; and, for clarity, the dimensions 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.

[0040] The orientation terms appearing in the following description are all the directions shown in the figures, and do not limit the nacelle, the transportation method of the nacelle, and the wind turbine generator set of the present application. In the description of the present 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 may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. The term "along a certain direction" should be understood in a broad sense. For example, it may be consistent with the direction, or have a component or projection in the direction. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] Please refer to Figure 1 , 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, including a tower barrel 100, a nacelle 200, a generator 300, and an impeller 400. The nacelle 200 is arranged at the top of the tower barrel 100. The generator 300 is arranged outside the nacelle 200, and of course, it may also be located inside the nacelle 200. The impeller 400 includes 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 through its hub 410. When the wind acts on the blades 420, the entire impeller 400 and the rotating shaft of the generator 300 are driven to rotate, so as to convert wind energy into electrical energy.

[0042] In the wind turbine generator sets in the prior art, the components of the unit need to be transported to a predetermined position for assembly. With the obvious trend of the unit becoming larger, the dimensions of the large components in the nacelle 200, such as the main shaft system, the gearbox, the generator 300, and the yaw, are getting larger and larger. 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 transformation costs need to be faced.

[0043] Therefore, in order to overcome the above-mentioned deficiencies, the embodiments of the present application further provide a nacelle 200 and a transportation method for the nacelle 200. The nacelle 200 can be used in the wind turbine generator set of the above embodiments and serve as a component of the wind turbine generator set. Of course, it can also be produced or sold separately as an independent component.

[0044] Please refer to Figure 1 and Figure 2 , Figure 2 which shows a schematic structural diagram of a nacelle 200 according to an embodiment of the present application.

[0045] The nacelle 200 provided by the embodiments of the present application is used to accommodate the fan components 500. The nacelle 200 includes a nacelle main body 1 and a mounting platform 2. The nacelle main body 1 has an accommodation cavity. An opening communicating with the accommodation cavity is provided on the surface of the nacelle main body 1 along the first direction X. The mounting platform 2 is arranged on the nacelle main body 1. The mounting platform 2 is configured to support the fan components 500. Wherein, the mounting platform 2 can move relative to the nacelle main body 1 to drive at least part of the fan components 500 to protrude from the nacelle main body 1 through the opening or be received in the accommodation cavity.

[0046] According to the nacelle 200 in the embodiments of the present application, it includes a nacelle main body 1 and a mounting platform 2. The fan components 500 can be fixed to the mounting platform 2. By making the mounting platform 2 movable relative to the nacelle main body 1, when transporting the nacelle 200, the fan components 500 can be driven by the mounting platform 2 to be received in the accommodation cavity, thereby reducing the volume of the nacelle 200 and saving the transportation cost of the nacelle 200. After the nacelle 200 is transported to a predetermined position, the fan components 500 can be driven by the mounting platform 2 to protrude at least partially from the nacelle main body 1 through the opening, thereby breaking through the volume limitation of the nacelle 200 and meeting the different space requirements of the transportation conditions and operation conditions of large-scale units without using split transportation.

[0047] Among them, the fan components 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 work and operation and maintenance of personnel climbing the tower after the unit operates, when transporting the nacelle 200, when at least part of the fan components 500 are received in the accommodation cavity, they can temporarily occupy the personnel passage to effectively utilize the passage space and reduce the transportation difficulty of the nacelle 200. And after the nacelle 200 is transported to a predetermined position, the fan components 500 can also be driven to protrude at least partially from the nacelle main body 1 by moving the mounting platform 2, which is simple and efficient to use.

[0048] It should be noted that after the nacelle 200 is transported to the predetermined position, part of the wind turbine component 500 can protrude from the nacelle main body 1, or all of it can protrude from the nacelle main body 1. And according to the installation position of the wind turbine component 500 on the installation platform 2, after the nacelle 200 is transported to the designated position, the installation platform 2 can be arranged with at least part of the opening protruding from the nacelle main body 1, or it can be located inside the nacelle main body 1, as long as it can meet the requirement that at least part of the wind turbine component 500 arranged on the installation platform 2 protrudes from the opening of the nacelle main body 1 to break through the volume limitation of the nacelle 200.

[0049] It can be understood that the first direction X can be the width direction of the nacelle main body 1. For example, an opening can be arranged on the side plate 111 of the nacelle main body 1, which can reduce the width dimension of the nacelle main body 1 itself, and by making the installation platform 2 drive at least part of the wind turbine component 500 to protrude from the opening of the side plate 111 of the nacelle main body 1, the ultra-wide layout of the nacelle space can be realized at extremely low cost while meeting the width limit requirement during the transportation of the nacelle 200.

[0050] Alternatively, the first direction X can also be the height direction of the nacelle main body 1. For example, an opening can be arranged on the top plate 112 or the bottom plate of the nacelle main body 1, which can reduce the height dimension of the nacelle main body 1 itself, and by making the installation platform 2 drive at least part of the wind turbine component 500 to protrude from the opening of the top plate 112 or the bottom plate of the nacelle main body 1, the ultra-high layout of the nacelle space can be realized at extremely low cost while meeting the height limit requirement during the transportation of the nacelle 200.

[0051] Alternatively, the first direction X can also be the length direction of the nacelle main body 1. For example, an opening can be arranged on the rear end plate 113 of the nacelle main body 1, which can reduce the length dimension of the nacelle main body 1 itself, and by making the installation platform 2 drive at least part of the wind turbine component 500 to protrude from the opening of the rear end plate 113 of the nacelle main body 1, the transportation difficulty of transportation conditions such as turning or lane changing during the transportation of the nacelle 200 can be reduced, and the ultra-long layout of the nacelle space can be realized at extremely low cost.

[0052] Optionally, the wind turbine component 500 can be set as at least one of an electrical cabinet, an inverter, and a transformer. When multiple wind turbine components 500 are provided, at least part of the multiple wind turbine components 500 can be arranged on the same installation platform 2, so that the multiple wind turbine components 500 can protrude from the nacelle main body 1 through the installation platform 2 at the same time. Or, multiple openings can also be arranged on the nacelle main body 1, and an installation platform 2 is provided for each opening, that is, components such as the electrical cabinet, control, and hydraulic components of the wind turbine generator set can be correspondingly installed on the corresponding installation platform 2, as long as the space requirements of the operating conditions of large-scale units can be met.

[0053] Among them, when multiple openings are provided on the nacelle main body 1, the two side plates 111 of the nacelle main body 1 arranged oppositely are defined as the first side plate and the second side plate. The multiple openings can be all provided on the same one of the first side plate, the second side plate, the top plate 112, the bottom plate and the rear end plate 113 of the nacelle main body 1, or can be respectively provided on at least two of the first side plate, the second side plate, the top plate 112, the bottom plate and the rear end plate 113 of the nacelle main body 1. The specific setting position and quantity of the openings can be arranged and adjusted according to the fan component 500, as long as the space requirements of the transportation condition and the operation condition of the large-scale unit can be met.

[0054] For the convenience of description, in the following embodiments and drawings, the first direction X is taken as the width direction of the nacelle main body 1, and only one fan component 500 is provided as an example for illustration.

[0055] In some alternative 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 accommodation cavity; in the second locking state, the fan component 500 at least partially protrudes out of the opening along the first direction X.

[0056] By enabling the mounting platform 2 to be provided with the first locking state and the second locking state, the mounting platform 2 can be fixed in the first locking state during the transportation process to prevent the mounting platform 2 from moving during transportation, and the mounting platform 2 can be fixed in the second locking state during the actual operation of the wind turbine generator set to ensure the reliability during the operation of the nacelle 200.

[0057] In some alternative embodiments, the mounting platform 2 linearly moves relative to the nacelle main body 1 through a linear guiding mechanism, or the mounting platform 2 is rotatably connected to the nacelle main body 1 through a rotating mechanism, and the extending direction of the rotation axis of the rotating mechanism and the nacelle main body 1 intersects with the first direction.

[0058] In the first case, the mounting platform 2 is connected to the nacelle main body 1 through a linear guiding mechanism. The linear guiding mechanism can be specifically set as one of a sliding groove, a gear-rack mechanism, a lead screw-nut mechanism or a telescopic rod, that is, the linear guiding mechanism can be adopted to drive the mounting platform 2 to translate relative to the nacelle main body 1, so that the mounting platform 2 changes its position relative to the nacelle main body 1 in the first direction X.

[0059] The linear guiding mechanism can specifically be manually driven. For example, when the linear guiding mechanism is set as a chute, a chute can be provided on the nacelle main body 1, and the installation platform 2 is pushed manually to drive the installation platform 2 to linearly move within the chute. Alternatively, the linear guiding mechanism can also be electrically driven. For example, when the linear guiding mechanism is a lead screw nut mechanism, a lead screw can be provided on the nacelle main body 1 extending along the first direction X, and the installation platform 2 is in threaded cooperation with the lead screw. Thus, when the motor drives the lead screw to rotate, the installation platform 2 can be driven to reciprocate along the first direction X to precisely control the moving distance of the installation platform 2 relative to the nacelle main body 1. Or, the linear guiding mechanism can also be hydraulically driven. For example, when the linear guiding mechanism is set as a telescopic rod, the installation platform 2 can be arranged at the output end of the telescopic rod to drive the telescopic rod to extend and retract along the first direction X through a hydraulic cylinder, so as to drive the installation platform 2 to linearly move relative to the nacelle main body 1.

[0060] In the second case, the installation platform 2 is connected to the nacelle main body 1 through a rotating mechanism (not shown in the figure). The rotating mechanism can specifically be set as a parallelogram mechanism or a hinge mechanism. By using the rotating mechanism to drive the installation platform 2 to rotate relative to the nacelle main body 1, the fan component 500 thereon can change its position relative to the nacelle main body 1 in the first direction X.

[0061] Among them, the specific structural form of the rotating mechanism can be adjusted according to the rotating direction of the rotating mechanism.

[0062] As an example, when the rotation axis of the installation platform 2 and the nacelle main body 1 extends along the second direction Y, that is, the length direction of the nacelle main body 1, the rotating mechanism can be set as a parallelogram mechanism to drive the installation platform 2 to rotate through the parallelogram mechanism, so that the fan component 500 changes its position relative to the nacelle main body 1 in the first direction X. Moreover, by setting the rotating mechanism as a parallelogram mechanism, it can also be ensured that when the installation platform 2 rotates, the installation surface for carrying the fan component 500 always remains horizontal to achieve stable support for the fan component 500.

[0063] When the rotation axis of the installation platform 2 and the nacelle main body 1 extends along the third direction Z, that is, the height direction of the nacelle main body 1, the rotating mechanism can be set as a hinge mechanism. The installation platform 2 can include a first connecting plate and a second connecting plate intersecting with each other. The first connecting plate is rotatably connected to the main frame 12, and the second connecting plate forms a horizontal installation surface for fixing the fan component 500. Thus, the fan component 500 can change its position relative to the nacelle main body 1 in the first direction X by rotating the first connecting plate relative to the main frame 12.

[0064] Please refer to Figures 2 to 4, considering that the fan component 500 has a certain weight, the installation platform 2 needs to have sufficient load-bearing capacity. In some alternative embodiments, the nacelle main body 1 includes a housing 11 and a main frame 12. The housing 11 encloses to form a receiving cavity with an opening. The main frame 12 is disposed in the receiving cavity. The installation platform 2 is disposed on the main frame 12, and the installation platform 2 can change its position relative to the main frame 12 in the first direction X.

[0065] Since the main frame 12 is the foundation of the nacelle main body 1, that is, the fan component 500 can be fixed on the installation platform 2, and by installing the installation platform 2 on the main frame 12 of the nacelle main body 1, the main frame 12 can bear the weight of devices such as the fan component 500 and the vibration during operation, so as to achieve stable loading of the fan component 500, and the overall structure is more reliable.

[0066] To enable the installation platform 2 to change its position relative to the main frame 12 in the first direction X, in some alternative embodiments, a chute 121 extending in the first direction X is provided on the main frame 12. The installation platform 2 is slidably connected to the chute 121, that is, the installation platform 2 can translate relative to the main frame 12 through the chute 121 to move the fan component 500 disposed on the installation platform 2 out of the receiving cavity. By adopting a sliding structure to move the installation platform 2, the structure is simple, it is more convenient for on-site disassembly and assembly, reduces the installation time, lowers the cost, and has high reliability.

[0067] Optionally, the chute 121 can be set as a V-shaped groove or a dovetail groove, and the installation platform 2 can be provided with a convex portion matching the chute 121 to enable the installation platform 2 to be translated relative to the main frame 12.

[0068] Please refer to Figures 3 to 6 , in some alternative embodiments, the chute 121 includes a sliding section 1211 and a first limiting section 1212 and a second limiting section 1213 respectively disposed at both ends of the sliding section 1211 along the first direction X. The first limiting section 1212 is located on the side closer to the opening relative to the second limiting section 1213. The installation platform 2 has a first locked state and a second locked state. In the first locked state, the installation platform 2 is clamped in the second limiting section 1213, and at least part of the fan component 500 is received in the receiving cavity. In the second locked state, the installation platform 2 is clamped in the first limiting section 1212, and at least part of the fan component 500 protrudes out of the opening along the first direction X.

[0069] Among them, Figure 3 and Figure 4 is a schematic structural diagram of the installation platform 2 in the first locked state, Figure 5 and Figure 6 is a schematic structural diagram of the installation platform 2 in the second locked state.

[0070] By providing a first limiting section 1212 and a second limiting section 1213 at both ends of the sliding groove 121, it is possible to ensure that the installation platform 2 can be effectively fixed and constrained at the two extreme positions within the sliding range, preventing the installation platform 2 from sliding during transportation, increasing the structural stability, and making it safer and more reliable.

[0071] In some alternative embodiments, first limiting holes K1 and second limiting holes K2 are spaced along the first direction X on the installation platform 2. The first limiting hole K1 is located at the extended end of the installation platform 2. The installation platform 2 further includes a limiting member 3, and the limiting member 3 is detachably connected to the first limiting hole K1 or the second limiting hole K2 to achieve the switching between the first locked state and the second locked state of the installation platform 2.

[0072] Moreover, by providing the limiting holes and arranging the limiting member 3 to pass through the limiting holes and the sliding groove 121, it is ensured that the installation platform 2 can only move along the first direction X and can be fastened at the limiting section position, guaranteeing the safety of the installation platform 2 during movement and the reliability during fastening.

[0073] It can be understood that the limiting member 3 can be set as a pin shaft assembly. Therefore, during the switching process of the installation platform 2 from the first locked state to the second locked state, the limiting member 3 can be simply loosened without being removed to utilize the limiting member 3 as a sliding rod. By moving the limiting member 3 along the sliding section 1211, the stability of the installation platform 2 moving along the main frame 12 can be improved. When the installation platform 2 moves to the extreme position, the limiting member 3 is then locked to the first limiting section 1212 or the second limiting section 1213 to lock the installation platform 2 to the first locked state or the second locked state.

[0074] Furthermore, in the first locked state, the first limiting hole K1 is aligned with the second limiting section 1213, and the limiting member 3 passes through the first limiting hole K1 and clamps the installation platform 2 to the second limiting section 1213. In the second locked state, the second limiting hole K2 is aligned with the first limiting section 1212, and the limiting member 3 passes through the second limiting hole K2 and clamps the installation platform 2 to the first limiting section 1212.

[0075] The above setting method can reduce the size of the main support's sliding groove 121 when the extended dimension of the installation platform 2 is fixed, or increase the extendable distance of the installation platform 2 under the condition of a limited length of the sliding groove 121, thereby increasing the protruding distance of the installation platform 2 along the first direction X relative to the accommodating cavity in the second locked state to increase the expandable space of the engine room 200.

[0076] Please refer to Figures 7 to 9 , in some alternative embodiments, a support hole K3 is further provided on the main frame 12, and the engine room 200 further includes a support member 4. In the second locked state, both ends of the support member 4 are respectively connected to the first limiting hole K1 and the support hole K3.

[0077] Since in the second locked state, the support member 4 protrudes at least partially from the main frame 12 in the first direction X, by providing the support member 4 to support the outer edge of the mounting platform 2, the load of the part of the mounting platform 2 that overhangs the main support can be borne by the support member 4, enhancing the structural stability.

[0078] It can be understood that the support member 4 is an inclined support, and its shape and size can be determined according to the weight of the fan component 500 to be installed on the mounting platform 2, as long as it can ensure the reliable support of the mounting platform 2 for the fan component 500 in the second locked state.

[0079] Please refer to Figures 3 to 7 , in some alternative embodiments, on the side of the main frame 12 close to the opening, support ribs 122 are arranged in pairs in the second direction Y, and the sliding grooves 121 are arranged on the support ribs 122. The mounting platform 2 includes a main body portion 21 and side portions 22 connected to both ends of the main body portion 21 in the second direction Y. The side portions 22 are respectively arranged on both sides of the support ribs 122 arranged in pairs, and are slidably connected to the support ribs 122 through the sliding grooves 121. The second direction Y intersects the first direction X.

[0080] By providing the support ribs 122 on the side of the main frame 12 close to the opening and providing the sliding grooves 121 on the support ribs 122 to realize the sliding of the mounting platform 2 along the sliding grooves 121, the structural form is simplified, facilitating processing and installation. The support ribs 122 and the side portions 22 arranged in pairs optimize the structural stress and ensure the stability of the support of the support ribs 122 for the mounting platform 2. The mounting platform 2 is clamped on the support ribs 122 through the side portions 22, further restricting the degrees of freedom of the mounting platform 2 in other directions and ensuring that the mounting platform 2 can move more smoothly in the first direction X.

[0081] Optionally, a bent portion 1221 can be provided at one end of the support rib 122 facing the main body portion 21 in the third direction Z to increase the stiffness of the support rib 122 through the bent portion 1221, making the support of the support rib 122 for the mounting platform 2 more stable.

[0082] Please refer to Figure 8 and Figure 9 , in some alternative embodiments, in the third direction Z, the first limiting section 1212 and the second limiting section 1213 protrude from the relative sliding section 1211 towards the side away from the mounting platform 2. The third direction Z, the first direction X and the second direction Y intersect pairwise.

[0083] That is, the height of the first limit section 1212 and the second limit section 1213 are lower than the height of the sliding section 1211, so that when the installation platform 2 moves to the two extreme positions, it can drive the limit member 3 downward into the first limit section 1212 and the second limit section 1213 through its own gravity, further ensuring the reliability of the fastening connection of the installation platform 2 at the extreme positions from a structural perspective.

[0084] Since the height of the first limit section 1212 and the second limit section 1213 is different from the height 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 arranged between the first limit section 1212 and the second limit section 1213 and the sliding section 1211.

[0085] On the one hand, it can ensure the stability of the installation platform 2 during the sliding process, and prevent the installation platform 2 from suddenly falling when moving to the extreme position, causing damage to the fan component 500. On the other hand, it can also reduce the resistance of the limit member 3 when sliding out of the first limit section 1212 and the second limit section 1213, so as to realize the switching of the installation platform 2 between the first locking state and the second locking state.

[0086] See also Figure 10 In some optional embodiments, the nacelle 200 further includes a cover plate 5, the cover plate 5 having a central area and an edge area, the central area is arranged to protrude relative to the edge area along the first direction X, and the edge area of ​​the cover plate 5 is connected to a side surface of the nacelle body 1 away from the accommodating cavity and snaps into the opening. By providing the cover plate 5, it can cover the opening side of the nacelle 200 and cover the fan component 500 protruding from the accommodating cavity, so as to seal the internal space of the nacelle 200 and improve the reliability of the fan component 500.

[0087] In the process of 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.

[0088] See also Figures 1 to 11 The embodiment of the present application further provides a method for transporting a cabin 200, comprising:

[0089] S1, providing the cabin 200 of the above embodiment, a fan component 500 is installed on the mounting platform 2, and controlling the mounting platform 2 to move so that the fan component 500 is at least partially accommodated in the accommodating cavity;

[0090] S2, moving the nacelle 200 to a designated location by means of a transportation vehicle, and controlling the installation platform 2 to move so that the fan component 500 is at least partially protruded from the nacelle body 1 through the opening.

[0091] In the method for transporting the nacelle 200 in the embodiment of the present application, during the transportation process, the fan component 500 is stored in the accommodating chamber, for example, the personnel passage in the accommodating chamber can be occupied first, thereby reducing the volume of the nacelle 200 and saving the transportation cost of the nacelle 200. After being transported to the designated location, the fan component 500 is arranged to protrude from the nacelle body 1 through the opening, thereby breaking through the volume limitation of the nacelle 200 and meeting the different space requirements of the transportation working conditions and the operating working conditions of the large-scale unit at a very low cost.

[0092] It is understandable that the means of transport may be a vehicle, a ship or other vehicles.

[0093] 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.

[0094] Since the fan component 500 is at least partially accommodated 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 aligned with 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.

[0095] 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 make the installation platform 2 slide 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 continuously to make the installation platform 2 slide 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, and 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 locking state, so that the fan component 500 at least partially protrudes out of the accommodating cavity.

[0096] 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.

[0097] In some optional embodiments, the cabin 200 further includes a cover plate 5, and after the step of moving the cabin 200 to a designated location by a transportation tool, the method further includes:

[0098] The cover plate 5 is buckled onto the opening of the cabin body 1 to seal the accommodating cavity.

[0099] Therefore, after the installation platform 2 is switched to the second locked state, the cover plate 5 can be further closed on the opening side of the engine nacelle 200 and cover the fan component 500 protruding from the accommodation cavity to seal the internal space of the engine nacelle 200 and improve the reliability of the fan component 500.

[0100] The wind turbine generator set of the embodiment of the present application has advantages such as low transportation cost and large internal space of the engine nacelle 200 because it includes the engine nacelle 200 of the above embodiment, and is more likely to be popularized and used.

[0101] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
