[0021] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] The following is combined with Figure 1-3 The utility model is described in further detail.

[0023] The utility model embodiment discloses a wind turbine nacelle cover. Figure 1-3 A wind turbine nacelle cover includes a cover body Ⅰ1 and a cover body Ⅱ2 that are spliced ​​together, wherein a connecting plate Ⅰ11 is extended inwardly at the end of the cover body Ⅰ1, and a connecting plate Ⅱ21 is extended inwardly at the end of the cover body Ⅱ2, wherein the connecting plate Ⅰ11 and the connecting plate Ⅱ21 are attached to each other and fixedly connected by bolts, wherein a transverse water diversion groove 12 is provided inwardly on a side of the cover body Ⅰ1 located away from the cover body Ⅱ2 and recessed therein, and a transverse pasting plate 22 for being attached to the transverse water diversion groove 12 is provided on a side of the cover body Ⅱ2 located close to the cover body Ⅰ1 and the connecting plate Ⅱ21. The transverse water diversion groove 12 can divert water from the surface of the cabin to prevent water accumulation on the surface of the cabin, thereby greatly improving the waterproof performance. At the same time, the application of this structure can also eliminate the addition of EPDM sealing strips during the installation of conventional flange docking structures, thereby saving material consumption and installation time. Similarly, the glass glue sealing used at the end of the base can also be eliminated when the structure is used, thereby greatly improving the installation time efficiency.

[0024] In this embodiment, the transverse water diversion trough 12 is gradually inclined downward from the middle to both sides, so that rainwater entering the transverse water diversion trough 12 can flow down to both sides of the cabin through the transverse water diversion trough 12 to avoid rainwater accumulation on the cabin.

[0025] In this embodiment, the cover body II2 is provided with a transverse water retaining strip 23 protruding outwardly on the side of the transverse plate 22 away from the cover body I1. The protruding transverse water retaining strip 23 can effectively prevent wind and rain from penetrating into the interior of the cabin cover, greatly improving the waterproof performance.

[0026] In this embodiment, the cover body I1 is located on one side of the transverse water diversion groove 12 close to the cover body II2 and protrudes outward and fits against the inner wall of the transverse water retaining strip 23. The cover body I1 protrudes outward and fits against the transverse water retaining strip 23, which can play a secondary waterproofing role.

[0027] In this embodiment, the cover body II2 is divided into two parts on the left and right sides. A left connecting plate 24 is longitudinally arranged on the inner side of the left side of the cover body II2. The left connecting plate 24 is connected to the connecting plate II21 on the left side of the cover body II2. A right connecting plate 25 is longitudinally arranged on the inner side of the right side of the cover body II2. The right connecting plate 25 is connected to the connecting plate II21 on the right side of the cover body II2. The left connecting plate 24 and the right connecting plate 25 are fixedly connected by bolts.

A longitudinal pasting plate 27 for fitting in the longitudinal water diversion groove 26 is provided on one side of the left side portion of the cover body Ⅱ2 close to the right side portion of the cover body Ⅱ2. The accumulated water on the cabin cover body Ⅱ2 can be drained away through the longitudinal water diversion groove 26, so that the accumulated water on the cabin can be drained away through the transverse water diversion groove 12 and the longitudinal water diversion groove 26, thereby realizing longitudinal and transverse drainage and achieving better drainage effect.

[0029] In this embodiment, a longitudinal water retaining strip 28 is provided on one side of the left side portion of the cover body II2 close to the right side portion of the cover body II2 and protrudes outward in the longitudinal direction. The longitudinal sticker plate 27 is provided on one side of the longitudinal water retaining strip 28 close to the right side portion of the cover body II2. The longitudinal water retaining strip 28 can effectively prevent wind and rain from penetrating into the interior of the cabin cover, thereby greatly improving the waterproof performance.

[0030] In this embodiment, the right side portion of the cover body II 2 is located between the longitudinal water diversion groove 26 and the right connecting plate 25, protrudes outward in the longitudinal direction and fits on the inner wall of the longitudinal water retaining strip 28. The outward protruding portion of the right side portion of the cover body II 2 can achieve a secondary waterproofing effect.

[0031] Finally, it should be noted that the horizontal direction in the above embodiments is the short side of the cabin cover, and the vertical direction is the long side of the cabin cover. The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
