[0021] Please refer to Figures 1 to 3 The present application provides a wind turbine nacelle, which comprises a plurality of nacelle pieces 100 and a plurality of connecting parts 200. The plurality of nacelle pieces 100 are assembled together through the plurality of connecting parts 200, and the connecting parts 200 are fixedly connected with the nacelle pieces 100. The nacelle piece 100 comprises a plurality of sheet materials 110, and the adjacent sheet materials 110 are fixedly connected. One of the adjacent sheet materials 110 is provided with a first connecting part 111, and the other is provided with a second connecting part 112. The first connecting part 111 is provided with a groove 1111, and the second connecting part 112 is provided with a protrusion 1121 matched with the groove 1111. The protrusion 1121 extends into the groove 1111, and the fixed connection between the first connecting part 111 and the second connecting part 112 is realized through the cooperation of the protrusion 1121 and the groove 1111, so as to realize the fixed connection of the adjacent sheet materials 110.
[0022] The number of the sheet 110 in each nacelle cover piece 100 is not limited in the present application. For example, each nacelle cover piece 100 can include two sheets 110, three sheets 110 or more sheets 110, which is adjusted according to the size of the nacelle cover piece 100. The wind turbine nacelle cover in the present application can not only meet the road transportation requirements by setting the nacelle cover piece 100 into multiple sheets 110, but also reduce the transportation cost of the nacelle cover and improve the transportation efficiency. Moreover, compared with the traditional bolt connection, the connection mode of the sheet 110 does not need to pre-tighten the bolts one by one, which can greatly improve the assembly efficiency of the nacelle cover, shorten the assembly cycle of the nacelle cover, improve the production efficiency, and does not need to reserve flanges on the sheet 110 for assembly, which can improve the effective utilization of space.
[0023] Please refer to Figure 2 The shape of the protrusion 1121 and the groove 1111 is not limited in the present application, as long as the shape of the protrusion 1121 is consistent with the shape of the groove 1111. For example, the shape of the protrusion 1121 is a cube, and the shape of the groove 1111 is also a cube. The shape of the protrusion 1121 is a cuboid, and the shape of the groove 1111 is also a cuboid. The shape of the protrusion 1121 is a trapezoid, and the shape of the groove 1111 is also a trapezoid. In an embodiment, the shape of the protrusion 1121 is a trapezoid, and the longer end of the trapezoid base faces the first connecting piece 111. The trapezoidal protrusion 1121 and the trapezoidal groove 1111 not only can increase the contact area of the first connecting piece 111 and the second connecting piece 112, but also can concentrate stress on the edge of the groove 1111, reduce stress concentration, and improve the tensile strength and fatigue resistance of the protrusion 1121. For example, the second connecting piece 112 is in interference fit with the first connecting piece 111, and the fixed connection of the second connecting piece 112 and the first connecting piece 111 realizes the fixed connection of the adjacent sheets 110. In the present embodiment, in order to improve the connection strength of the adjacent sheets 110, the first connecting piece 111 and the second connecting piece 112 are fixedly connected by sealing glue, and the type of the sealing glue is not limited herein, for example, the commonly used sealing glue in the art such as silicone sealing glue, polyurethane sealing glue, acrylic sealing glue, epoxy sealing glue, etc. can be selected. For example, the thickness of the sealing glue is 1-2 mm.
[0024] Please refer to Figure 2In an embodiment, the first connecting member 111 is integrally formed with the corresponding sheet 110, and the second connecting member 112 is integrally formed with the corresponding sheet 110.

For example, the first connecting member 111 and the first sheet 120 are integrally formed by a vacuum infusion process. The specific operation is as follows: lay a first glass fiber layer 121 on a mold, arrange a first core material 122, position the first sheet 120 to pull the first connecting member 111, and then integrally form by a vacuum infusion process. The surface of the first sheet 120 pulling the first connecting member 111 needs to be the surface of the release cloth in use, so as to ensure the interfacial bonding force with the first glass fiber layer 121. The second connecting member 112 and the second sheet 130 are integrally formed by a vacuum infusion process. The specific operation is as follows: lay a second glass fiber layer 131 on a mold, arrange a second core material 132, position the second sheet 130 to pull the second connecting member 112, and then integrally form by a vacuum infusion process. The surface of the second sheet 130 pulling the second connecting member 112 needs to be the surface of the release cloth in use, so as to ensure the interfacial bonding force with the second glass fiber layer 131. In this application, the number of connecting members on each sheet 110 is not limited, and can be adaptively adjusted according to the size of the sheet 110, as long as the stable connection of adjacent sheets 110 is met.

The assembly process of the wind turbine nacelle is as follows: first, the plurality of sheets 110 are assembled into nacelle cover pieces 100, and then the nacelle cover pieces 100 are assembled through the connecting parts 200 to form a nacelle main body. Specifically, a sealing glue with a thickness of 1-2 mm is applied in the groove 1111 of the first connecting piece 111, the protrusion 1121 on the second connecting piece 112 is inserted into the groove 1111 of the first connecting piece 111, the overflowing sealing glue is cleaned, and the assembly of the nacelle main body is completed after the sealing glue is solidified. Then, the nacelle main body is fixedly connected with the special-shaped structure 300, the assembly of the wind turbine nacelle is completed, and the assembled nacelle is assembled onto the nacelle.
