However, how to design each piece module and how to splice multiple piece modules together urgently need to be solved. Summary of the Utility Model

[0003] Therefore, the purpose of the present utility model is to provide a nacelle cover for a wind turbine generator set and a wind turbine generator set to solve at least one of the problems existing in the above-mentioned prior art or related art.

[0004] The first aspect embodiment of the present utility model provides a nacelle cover for a wind turbine generator set. The nacelle cover includes a top cover, and the top cover includes a plurality of top cover modules spliced together. Each top cover module includes: a profile frame and a metal panel disposed on the profile frame. The profile frame has a laterally open installation groove, and the edge of the metal panel is inserted into the installation groove and connected to the profile frame through a first connecting member.

[0005] The top cover of the nacelle cover provided in the embodiment of this aspect includes a plurality of top cover modules spliced together, so that each top cover module includes two parts, namely a profile frame and a metal panel, which is convenient for each to be processed and formed, and reduces the processing difficulty. Moreover, the metal panel is inserted into the installation groove on one side of the profile frame, and the two are connected together through a first connecting member. The connection is firm, and it is convenient for the metal panel to be quickly and accurately installed in place by aligning with the position where the installation groove is located, improving the assembly efficiency.

[0006] In some embodiments, the metal panel is a single-layer panel. It is light in weight, convenient for installation and transportation, easy to process, and uses less materials, which is beneficial to cost reduction.

[0007] In some embodiments, the installation groove has a first groove wall and a second groove wall distributed oppositely. The edge of the metal panel is in contact with the first groove wall, and a part of the metal panel is spaced from the second groove wall. The first connecting member connects the edge of the metal panel and the first groove wall.

[0008] In some embodiments, each top cover module includes at least two profile frames. The first profile frame and the second profile frame are distributed at opposite ends of the metal panel in a first direction. Two adjacent top cover modules in the first direction are butted together through the first profile frame and the second profile frame.

[0009] In these embodiments, two adjacent top cover modules are butted together through their respective profile frames. Since the profile frames have high structural strength and are not easily deformed, it is beneficial for the two top cover modules to be firmly spliced together.

[0010] In some embodiments, the first profile frame has a first connection wall for fitting with the second profile frame, the second profile frame has a second connection wall for fitting with the first profile frame, the first profile frame further has a first accommodation cavity located on one side of the first connection wall, the bottom of the first accommodation cavity has a first opening, the second profile frame further has a second accommodation cavity located on one side of the second connection wall, and the bottom of the second accommodation cavity has a second opening; the top cover further includes a second connecting member, and the second connecting member extends into the first accommodation cavity and the second accommodation cavity and penetrates through the first connection wall and the second connection wall.

[0011] In these embodiments, the second connecting member can extend into the first accommodation cavity through the first opening and penetrate through the first connection wall and the second connection wall, or can extend into the second accommodation cavity through the second opening and penetrate through the first connection wall and the second connection wall. The second connecting member can butt the two profile frames together inside the two profile frames, and the connection is firm. Moreover, the second connecting member is hidden in the accommodation cavities of the two profile frames, and the appearance effect is good.

[0012] In some embodiments, the top cover further includes a sealing member, and the sealing member is clamped between the first connection wall and the second connection wall. The sealing member can play a role in blocking water and dust, preventing rainwater or impurities from entering the interior of the engine cover through the gap between the two connection walls. In addition, in cooperation with the second connecting member to connect the first connection wall and the second connection wall together inside the two profile frames, it is beneficial to assist the first connection wall and the second connection wall to clamp the sealing member, thereby improving the sealing effect.

[0013] In some embodiments, the top of the first connection wall has a protruding portion protruding upward, and the top of the second connection wall is curled toward the direction where the protruding portion is located to form a wrapping portion, and the wrapping portion wraps around the outside of the protruding portion.

[0014] In these embodiments, the design of the protruding portion and the wrapping portion can extend the path for external rainwater to enter the gap between the first connection wall and the second connection wall, and the gap between the protruding portion and the wrapping portion can also form a labyrinth waterproof channel, improving the waterproof effect. Especially in cooperation with the sealing member between the first connection wall and the second connection wall, double waterproofing can better prevent rainwater from entering the interior of the engine cover.

[0015] In some embodiments, the first connecting member is a rivet or a bolt. The structure is simple and the cost is low.

[0016] In some embodiments, the profile frame is an aluminum alloy profile frame, and the metal panel is an aluminum alloy panel. It is light in weight, convenient for installation and transportation, and not easily corroded.

[0034] Next, in conjunction with Figures 1 to 3 the nacelle cover 1 provided by the embodiments of the present utility model for a wind turbine will be introduced.

[0035] As Figures 1 to 3 shown, an embodiment of the first aspect of the present utility model provides a nacelle cover 1 for a wind turbine. The nacelle cover 1 includes a top cover 2. The top cover 2 includes a plurality of top cover modules 20 spliced together. Each top cover module 20 includes: a profile frame 210 and a metal panel 220 disposed on the profile frame 210. The profile frame 210 has an installation groove 211 with a lateral opening. The edge of the metal panel 220 is inserted into the installation groove 211 and is connected to the profile frame 210 through a first connecting member.

[0036] The top cover 2 of the nacelle cover 1 provided by the embodiments of this aspect includes a plurality of top cover modules 20 spliced together, so that each top cover module 20 includes two parts, namely a profile frame 210 and a metal panel 220, which is convenient for processing and forming respectively, reduces the processing difficulty, and is convenient for transportation. Moreover, the metal panel 220 is inserted into the installation groove 211 on one side of the profile frame 210, and the two are connected together through a first connecting member, which is convenient for the metal panel 220 to be quickly and accurately installed in place by aligning with the position where the installation groove 211 is located, improves the assembly efficiency, and the connection is firm.

[0037] Moreover, since the edge of the metal panel 220 is inserted into the installation groove 211 of the profile frame 210, the installation groove 211 can limit the position of the metal panel 220. Even if the first connecting member becomes loose, the metal panel 220 will not move extensively and fall out of the profile frame 210, thus improving safety. In addition, the edge of the metal panel 220 is hidden inside the installation groove 211, resulting in a good appearance effect.

[0038] Among them, the metal panel 220 can be a single-layer panel. It is light in weight, convenient for installation and transportation, easy to process, and uses less materials, which is beneficial to cost reduction.

[0039] In addition, the installation groove 211 has a first groove wall 2111 and a second groove wall 2112 that are oppositely distributed, so that the edge of the metal panel 220 fits against the first groove wall 2111, and a part of the metal panel 220 is spaced apart from the second groove wall 2112, enabling the first connecting member to connect the edge of the metal panel 220 and the first groove wall 2111. Optionally, the remaining part of the metal panel can be provided with reinforcing ribs, which contact the second groove wall through the reinforcing ribs to enhance the strength of the engine nacelle.

[0040] There is a gap between a part of the metal panel 220 and the second groove wall 2112, and components that cooperate with the first connecting member can be arranged in this gap. That is to say, the connection point between the metal panel 220 and the profile frame 210 is opposite to this gap, facilitating the connection between the metal panel 220 and the profile frame 210. For example, the first connecting member can be a bolt, and a nut is placed in the gap to cooperate with the bolt to achieve clamping of the metal panel 220 and the first groove wall 2111.

[0041] In addition, when the engine nacelle cover is in a normal use state, the first groove wall 2111 can be located above the second groove wall 2112. On the one hand, this makes it so that there is no large gap between the metal panel 220 and the first groove wall 2111, resulting in a good appearance effect; on the other hand, it can prevent external rainwater or impurities from depositing in the gap between the metal panel 220 and the first groove wall 2111 and even entering the engine nacelle cover 1, reducing the probability of pollution of the engine nacelle cover 1.

[0042] In specific applications, the first connecting member can be a rivet, a bolt, a blind rivet screw, etc. It has a simple structure and low cost.

[0043] Furthermore, in some embodiments, such as Figure 3As shown, each top cover module 20 includes at least two profile frames 210. The at least two profile frames 210 include a first profile frame 230 and a second profile frame 240. The first profile frame 230 and the second profile frame 240 are distributed at opposite ends of the metal panel 220 in a first direction. Two adjacent top cover modules 20 in the first direction are butted together through the first profile frame 230 and the second profile frame 240.

[0044] In these embodiments, two adjacent top cover modules 20 are butted together through their respective profile frames 210. Since the profile frames 210 have high structural strength and are not easily deformed, it is beneficial for the two top cover modules 20 to be firmly spliced together.

[0045] In specific applications, a profile frame 210 can also be connected to each edge of the metal panel 220, so that two adjacent metal panels 220 in any direction are connected together through two adjacent profile frames 210, or the profile frames 210 can be connected to the edges of the metal panel 220 according to requirements.

[0046] Figure 3 The connection method of two adjacent top cover modules 20 is shown in Figure 3 The left top cover module 20 in includes a metal panel 220 and a first profile frame 230 connected to the metal panel 220. Figure 3 The right top cover module 20 in includes a metal panel 220 and a second profile frame 240 connected to the metal panel 220. The first profile frame 230 and the second profile frame 240 are butted together to realize the splicing of two adjacent top cover modules 20.

[0047] For the specific connection method of the first profile frame 230 and the second profile frame 240, further, in some embodiments, as Figure 3 shown, the first profile frame 230 has a first connection wall 231 for fitting with the second profile frame 240. The second profile frame 240 has a second connection wall 241 for fitting with the first profile frame 230. The first profile frame 230 also has a first accommodation cavity 232 on one side of the first connection wall 231. The bottom of the first accommodation cavity 232 has a first opening 233. The second profile frame 240 also has a second accommodation cavity 242 on one side of the second connection wall 241. The bottom of the second accommodation cavity 242 has a second opening 243. The top cover 2 further includes a second connector 30. The second connector 30 extends into the first accommodation cavity 232 and the second accommodation cavity 242 and penetrates through the first connection wall 231 and the second connection wall 241.

[0048] In these embodiments, the second connecting member 30 can extend into the first accommodating cavity 232 through the first opening 233, penetrate through the first connecting wall 231 and the second connecting wall 241, or can extend into the second accommodating cavity 242 through the second opening 243, penetrate through the first connecting wall 231 and the second connecting wall 241. The second connecting member 30 can dock the two profile frames 210 together inside, with a firm connection. Moreover, the second connecting member 30 is hidden in the accommodating cavities of the two profile frames 210, resulting in a good appearance effect.

[0049] The second connecting member 30 can be a bolt or a blind rivet screw, etc.

[0050] Furthermore, to prevent external rainwater from entering the interior of the nacelle cover 1 through the gap between the first connecting wall 231 and the second connecting wall 241, in some embodiments, as Figure 3 shown, the top cover 2 further includes a seal 40, and the seal 40 is clamped between the first connecting wall 231 and the second connecting wall 241. The seal 40 can play a role in blocking water and dust, preventing rainwater or impurities from entering the interior of the nacelle cover 1 through the gap between the two connecting walls.

[0051] In this embodiment, the second connecting member 30 connects the first connecting wall 231 and the second connecting wall 241 together inside the two profile frames 210. When the second connecting member 30 can tighten the first connecting wall 231 and the second connecting wall 241, it is beneficial to clamp the seal 40 on a large area and relatively evenly by means of the tightening of the second connecting member 30, thereby improving the sealing effect.

[0052] As an example, the second connecting member 30 is a bolt. The second connecting member 30 is inserted into the first accommodating cavity 232 through the first opening 233, and then penetrates through the first connecting wall 231, the seal 40, and the second connecting wall 241 and extends into the second accommodating cavity 242. The nut is placed into the second accommodating cavity 242 from the second opening 243 and tightened on the second connecting member 30. The cooperation of the bolt and the nut not only realizes the firm connection of the two profile frames 210, but also can clamp the seal 40. The seal 40 can be a sealing strip.

[0053] To improve the waterproof effect, further, in some embodiments, as Figure 3 shown, the top of the first connecting wall 231 has a protruding portion 234 protruding upward, and the top of the second connecting wall 241 is curled toward the direction where the protruding portion 234 is located to form a wrapping portion 244, and the wrapping portion 244 wraps around the outside of the protruding portion 234.

[0054] In these embodiments, the design of the protruding portion 234 and the wrapping portion 244 can extend the path for external rainwater to enter the gap between the first connecting wall 231 and the second connecting wall 241, improving the waterproof effect. Especially when cooperating with the seal 40 between the first connecting wall 231 and the second connecting wall 241, double waterproofing can better prevent rainwater from entering the interior of the engine hood 1.

[0055] In addition, when connecting the first profile frame 230 and the second profile frame 240 together, the position of the wrapping portion 244 can be aligned first, the protruding portion 234 can be inserted into the wrapping portion 244, and then the two can be connected together by the second connecting member 30, which is beneficial for the first profile frame 230 and the second profile frame 240 to be quickly and accurately butted in place, improving the assembly efficiency.

[0056] As an example, as Figure 3 shown, the cross-section of the wrapping portion 244 is generally in a U-shape, and the protruding portion 234 is inserted into the bottom opening of the U-shape. In this way, rainwater needs to enter the gap between one side of the protruding portion 234 and the wrapping portion 244 through the downward-opening entrance, and then needs to exceed the protruding portion 234 to enter the gap between the other side of the protruding portion 234 and the wrapping portion 244, and finally may enter the gap between the first connecting wall 231 and the second connecting wall 241, with good waterproof effect.

[0057] As an example, the upper surface of the protruding portion 234 is a wavy surface, and the surface of the wrapping portion 244 that fits with the protruding portion 234 is also a wavy surface. The two enclose a waterproof channel extending in a wavy shape, and each wave crest is beneficial for blocking rainwater from entering the gap between the first connecting wall 231 and the second connecting wall 241, with good waterproof effect.

[0058] The specific shapes of the protruding portion 234 and the wrapping portion 244 can be various, and will not be listed one by one here.

[0059] In a specific embodiment, as Figure 3 shown, Figure 3 sealant strips are filled at the docking joints of the left and right top cover modules 20 in the figure. Both the first profile frame 230 and the second profile frame 240 are aluminum profiles, and the forming process of the aluminum profiles is pultrusion. With the help of the process characteristics of aluminum profiles, a labyrinth waterproof channel is added to the outer surface of the joint of the top cover module 20. Specifically, the protruding portion 234 and the wrapping portion 244 are used to form the labyrinth waterproof channel, and the reliability of the top cover seal is increased by using the structural waterproof method.

[0060] Furthermore, in some embodiments, the profile frame 210 is an aluminum alloy profile frame, and the metal panel 220 is an aluminum alloy panel. It is light in weight, convenient for installation and transportation, and not easily corroded.

[0061] Of course, the profile frame 210 can also be a stainless steel frame or other frames that are not easily corroded. The material of the profile frame 210 can be the same as or different from that of the metal panel 220.

[0062] Further, in some embodiments, the nacelle cover 1 further includes side walls and a bottom cover. The top of the side walls is connected to the top cover 2, and the bottom cover is connected to the bottom of the side walls. The top cover 2, the side walls, and the bottom cover enclose the cavity of the nacelle cover 1. The side walls can include a plurality of side wall modules spliced together, and the bottom cover can also include a plurality of bottom cover modules spliced together. Each side wall module and each bottom cover module can each have a corresponding metal panel and profile frame. The connection manner of the panel and the profile frame can be the same as or similar to that of the top cover module 20, and adjacent modules can also be connected together through the profile frame, and the connection structure can also be the same as or similar to that of the top cover module 20.

The wind turbine generator provided by the embodiments of this aspect has the beneficial effects of any one of the above embodiments due to having the nacelle cover 1 in any one of the above embodiments, and will not be described in detail here.

[0064] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention defined by the claims.
