[0033] To further clarify the purpose, technical solutions, and advantages of the utility model, the following description of the technical solutions in the utility model is provided in conjunction with the accompanying drawings. Obviously, the embodiments described are only a portion of the embodiments of the utility model, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in the utility model without inventive effort are also within the scope of protection of the utility model.

Therefore, they cannot be understood as limitations on the embodiments of the present invention.

[0035] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary.

[0036] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature on the second feature may be a direct connection between the first and second features, or the first and second features may be indirectly connected through an intermediate medium.

[0037] In the description of this specification, the reference terms "some embodiments", "examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0038] The cabin cover usually includes a top cover panel, a side wall panel and a bottom cover panel. The top cover panel is connected to the top of the side wall panel, and the bottom cover panel is connected to the bottom of the side wall panel. The three of them form the cover cavity of the cabin cover. As the power generation of wind turbines gradually increases, the size of the cabin cover also gradually increases, and it becomes difficult to hoist the cabin cover as a whole. Therefore, the related art adopts a solution of hoisting the side wall panels first and then hoisting the top cover panels. However, there is a demand for the reliability of the connection of the top cover panel placed on the side wall panel, and after the top cover panel is placed on the side wall panel, the waterproofing problem of the connection position between the two also needs to be solved. Of course, in addition to the above-mentioned problems during the hoisting process, the cabin cover will also have corresponding problems when assembled on land. Therefore, the embodiment of the utility model proposes a profile structure and a cabin cover using the profile structure to overcome the above-mentioned problems.

[0039] The following will be combined Figures 1 to 6 The following describes a profile structure provided by an embodiment of the present invention and a nacelle cover 60 using the profile structure.

[0040] This embodiment provides a profile structure, including a profile body, a connecting portion and a waterproof structure.

[0041] The main body of the profile is formed with a hollow inner cavity. This saves materials, reduces costs, and increases structural strength. Of course, at least one reinforcing rib can also be added to the hollow inner cavity to increase the structural strength of the main body of the profile.

[0042] The connecting portion extends from the outer sidewall of the main profile away from the main profile and is used to interconnect with the panels of the nacelle cover 60. The use of the connecting portion protruding from the main profile to connect the panels facilitates connection. Furthermore, the profile structure, connected to the panels via the connecting portion, reinforces the panels and prevents deformation. Furthermore, the two profile structures allow two adjacent panels to be connected together, making the connection more convenient and less prone to deformation, thereby improving the reliability of the assembly connection of the split nacelle cover 60.

[0043] The waterproof structure is formed on the profile body and extends along the length direction of the profile body. The waterproof structure is used to prevent external rainwater from entering the interior of the nacelle cover 60. It can achieve multi-position waterproofing and prevent external rainwater from entering the interior of the nacelle cover 60 along the profile structure.

[0044] Among them, the profile structure can be connected to the top cover panel 30 of the cabin cover 60, or can be connected to the side wall panel 40 of the cabin cover 60, or the profile structure can be connected to both the top cover panel 30 and the side wall panel 40. In this way, when the cabin cover 60 is hoisted and the top cover panel 30 is lowered, the top cover panel 30 and the side wall panel 40 can be connected together through the profile structures connected thereto, which has good connection reliability and prevents external rainwater from entering the interior of the cabin cover 60 along the profile structure.

[0045] In this case, the top cover panel 30 of the nacelle cover 60 can be comprised of multiple sub-panels, facilitating the stacking and transportation of the large-sized nacelle cover 60. The profile structure can be connected to the outer edge of the entire top cover panel 30. Of course, the top cover panel 30 of the nacelle cover 60 can also be a single, integral panel, with the profile structure connected to the edge of the entire panel. Similarly, the side wall panels 40 of the nacelle cover 60 can also be comprised of multiple sub-panels, or the side wall panels 40 can be a single, integral panel, in which case the profile structure can be connected to the top of the entire side wall panel 40.

[0046] Furthermore, the profile structure can also connect the bottom cover panel of the nacelle cover 60 and the entire bottom of the side wall panel 40, ensuring a reliable connection between the side wall panel 40 and the bottom cover panel. This ensures a reliable connection between the side wall panel 40 and the bottom cover panel, regardless of whether the bottom cover panel is hoisted together with the side wall panel 40 or before the side wall panel 40. The connection position of the profile structure can be designed according to requirements.

[0047] Hereinafter, a specific structure of a profile structure will be described by taking a profile structure and a top cover panel 30 of a nacelle cover 60 as an example. Herein, the profile structure for connecting with the top cover panel 30 of the nacelle cover 60 is defined as a first profile 10 .

[0048] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the first profile 10 includes a first profile body 110 and a first connecting portion 120. The first connecting portion 120 is connected to the first profile body 110 and is located on one side of the first profile body 110. The first connecting portion 120 is provided with a mounting hole 121, which is used to connect to the top cover panel 30 of the nacelle cover 60. Bolts or rivets can be used to pass through the mounting hole 121 and the top cover panel 30 to facilitate a secure connection between the first profile 10 and the top cover panel 30.

[0049] The first profile 10 also includes a first waterproof structure, which includes a drainage groove 140 formed between the first profile body 110 and the first connecting portion 120. The drainage groove 140 is arranged opposite to the mounting hole 121, and the groove wall of the drainage groove 140 has a drainage hole 141 connected to the outside. In this way, when the first profile 10 is assembled on the top cover panel 30, the drainage groove 140 can be located directly below the mounting hole 121. Figures 3 to 5 In this way, after rainwater from the outside drops onto the top cover panel 30, even if it flows into the mounting hole 121, it will drop into the drainage groove 140 under the action of gravity, and then be discharged along the drainage hole 141, and will not drop directly into the interior of the cabin. This can prevent rainwater from the outside from entering the interior of the cabin cover 60 along the connection gap between the first profile 10 and the top cover panel 30, and has a good waterproof effect.

[0050] As an example, Figure 1 、 Figure 3 and Figure 5 As shown, the first connecting portion 120 is a bending portion, the first end of the bending portion is uprightly arranged on the first side wall 111 of the first profile body 110, and the second end of the bending portion is bent toward the direction of the first side wall 111, and a side mounting groove 130 with an opening is formed between the first side wall 111 and the bending portion, and the top cover panel 30 of the cabin cover 60 can be inserted into the mounting groove 130.

[0051] In this example, the first connecting portion 120 is designed as a bending portion, and the edge of the top cover panel 30 is inserted into the mounting groove 130, which is conducive to quickly finding the correct position for the two to be docked together, thereby improving assembly efficiency. Moreover, the mounting groove 130 can limit the top cover panel 30, which is conducive to improving the connection stability between the top cover panel 30 and the first profile 10. Moreover, after the edge of the top cover panel 30 is inserted into the mounting groove 130, it can be directly placed in the mounting groove 130, so that when the screw is inserted from top to bottom into the mounting hole 121 and the top cover panel 30, there is no need to prop up the top cover panel 30 to make it close to the first connecting portion 120, and the connection is convenient. In addition, the first profile 10 and the top cover panel 30 are connected firmly by screws. Of course, the screws can also be replaced by connectors such as latches and rivet screws.

[0052] However, since the design of the mounting hole 121 may cause water ingress, and the assembly gap between the top cover panel 30 and the first connecting part 120 may also cause water ingress, sealant may be filled in the assembly gap between the top cover panel 30 and the first connecting part 120, and sealant may be applied around the mounting hole 121. However, the sealant may also age after long-term use, and there is a certain risk of failure.

[0053] Therefore, in this embodiment, see Figures 3 to 5 The portion where the first side wall 111 connects to the first end of the bent portion is recessed in a direction away from the first connecting portion 120, thereby forming a drainage groove 140. Drain holes 141 are formed in the groove wall of the mounting groove 130 near the first end of the bent portion. Rainwater that seeps in through the mounting holes 121 or through the gap between the edge of the roof panel 30 and the first connecting portion 120 drips into the drainage groove 140 and is finally drained out through the drainage holes 141, thereby preventing water accumulation inside the nacelle 60.

[0054] Of course, in order to improve the drainage effect, the first side wall 111 can also be set at an angle, specifically, the end of the first side wall 111 away from the recess is higher than the end close to the recess. In this way, even if the rainwater does not fall into the drainage groove 140, it will slide along the first groove wall of the installation groove 130 into the drainage groove 140 and finally be discharged from the cabin cover 60.

[0055] Of course, in other embodiments, the recess may not be provided, but the mounting groove 130 may be directly used as the drainage groove 140, and the drainage hole 141 may be directly provided on the groove wall of the mounting groove 130. In this way, the first side wall 111 needs to be inclined, specifically, the end of the first side wall 111 away from the drainage hole 141 is higher than the end close to the drainage hole 141, so that the rainwater dripping from the mounting hole 121 flows directly along the first side wall 111 to the drainage hole 141, and finally flows out from the drainage hole 141.

[0056] The first profile 10 is connected to the roof panel 30 of the nacelle cover 60 and prevents rainwater from entering the interior of the nacelle cover 60 through the connection between the two. Of course, the first profile 10 can also serve as a connection to the side wall panels 40 of the nacelle cover 60. This requires further consideration of how the first profile 10 is connected to the side wall panels 40 and the waterproofing of the corresponding positions.

[0057] Therefore, further, Figure 1 、 Figure 3 and Figure 4As shown, the first profile body 110 can also have a second side wall 112 opposite to the first side wall 111, and a recess is provided on the second side wall 112. The profile structure connected to the top of the side wall panel 40 is defined as the second profile 20. A protrusion is provided on the third side wall 211 of the second profile body 210 of the second profile 20. The recess is also formed as a waterproof structure of the first profile 10, and the protrusion is also formed as a waterproof structure of the second profile 20. The second side wall 112 of the first profile 10 and the third side wall 211 of the second profile 20 are configured to be able to dock through the complementary protrusions and recesses. Here, the third side wall 211 can be the upward side wall of the second profile body 210 when applied to the cabin cover 60. Similarly, the second side wall 112 of the first profile body 110 can be the downward side wall of the second profile body 210 when applied to the cabin cover 60, so that when the first profile 10 falls onto the second profile 20, the recessed portion on the second side wall 112 and the convex portion on the third side wall 211 cooperate with each other.

[0058] The design of the convex and concave parts, on the one hand, is conducive to the rapid docking of the two, avoiding large-scale movement of the top cover panel 30 relative to the side wall panel 40, and facilitating the top cover panel 30 to fall stably to the top of the side wall panel 40 during the lifting process; on the other hand, it can prevent external rainwater from flowing smoothly into the interior of the cabin cover 60 along the assembly gap between the second side wall 112 and the third side wall 211, and will be blocked by the convex and concave parts, and the convex and concave parts will also extend the length of the assembly gap, thereby effectively preventing rainwater from entering the interior of the cabin cover 60, achieving a good waterproof effect.

[0059] In addition, reference Figure 3 and Figure 4 The convex and concave portions can also be arranged close to the outer edge of the second side wall 112, that is, close to the side wall panel 40. If rainwater from the outside enters through the gap between the first profile 10 and the second profile 20, it can be blocked by the convex portion and flow downward along the convex portion, and finally flow back to the outside of the nacelle cover 60, thereby avoiding water accumulation in the connection gap between the first profile 10 and the second profile 20.

[0060] Of course, a convex portion may be provided on the second side wall 112 and a concave portion may be provided on the third side wall 211 of the second profile body 210 so that the convex portion and the concave portion cooperate with each other to achieve the above-mentioned effect.

[0061] As an example, Figure 1 、 Figure 3 and Figure 4 As shown, a portion of the second side wall 112 of the first profile body 110 forms a water retaining groove 150, which is configured as a concave portion. A portion of the third side wall 211 of the second profile body 210 forms a protruding water retaining rib 230, which is configured as a convex portion; the water retaining rib 230 is configured to be inserted into the water retaining groove 150.

[0062] As an example, a portion of the second side wall 112 of the first profile body 110 is wavy (not shown), and a portion of the third side wall 211 of the second profile body 210 is wavy (not shown). The two wavy surfaces are matched and butted together to achieve waterproofing. The concave portion of the wavy surface on the second side wall 112 can be used as a recessed portion, and the convex portion of the wavy surface on the third side wall 211 can be used as a convex portion.

[0063] The specific structures of the convex and concave parts can be various and are not limited to the above examples.

[0064] In addition, in order to achieve a firm connection between the first profile 10 and the second profile 20, corresponding bolt holes 160 can be formed on the second side wall 112 of the first profile body 110 and the third side wall 211 of the second profile body 210, respectively, and bolts are passed through the bolt holes 160 to firmly connect the two together.

[0065] Specifically, a avoidance hole can be provided on the fourth side wall 212 opposite to the third side wall 211 on the second profile body 210. The installer inserts the T-shaped bolt 50 from the avoidance hole and the bolt hole 160 on the third side wall 211 into the bolt hole 160 on the second side wall 112 on the inner side of the cabin cover 60, rotates it 90°, and hangs the T-shaped bolt 50 on the second side wall 112. Then, the nut is extended into the hollow inner cavity of the second profile body 210 through the avoidance hole and screwed on the T-shaped bolt 50 to achieve a fastened connection between the second side wall 112 and the third side wall 211.

[0066] Of course, other methods can also be used to connect the first profile 10 and the second profile 20. For example, the T-bolt 50 can be replaced with a connecting piece such as a rivet screw, which is inserted into the bolt holes 160 of the second side wall 112 and the third side wall 211 through the avoidance hole to connect the two together by rivet.

[0067] In order to prevent the connecting member connecting the first profile 10 and the second profile 20 from being contaminated by rainwater, the bolt hole 160 on the second side wall 112 can be located on the side of the convex part or the concave part away from the portion where the first connecting part 120 is connected to the first side wall 111, and the bolt hole 160 on the third side wall 211 can be located on the side of the convex part or the concave part away from the second connecting part 220. Figure 3 and Figure 4 , so that the bolt hole 160 on the second side wall 112 is closer to the inner side of the nacelle cover 60 relative to the concave portion, and similarly the bolt hole 160 on the third side wall 211 is closer to the inner side of the nacelle cover 60 relative to the convex portion, so that when rainwater from the outside comes in, Figure 3 and Figure 4When the connecting piece 10 and the second profile 20 enter the connection gap, it will be blocked by the convex part and the concave part, which can prevent the connecting piece inserted into the two bolt holes 160 from being contaminated by rainwater.

[0068] In addition, reference Figure 1 、 Figure 3 and Figure 4 Furthermore, a connection interface 170 for connecting to the internal structure of the nacelle cover 60 can be formed on the first profile body 110 and the fifth side wall 113 adjacent to the first side wall 111. This connection interface 170 can be connected to other profiles to support the roof panel 30, or it can be connected to other components, thereby preventing other components from being directly connected to the roof panel 30 and increasing the load-bearing capacity of the roof panel 30.

[0069] Hereinafter, another profile structure will be described using the profile structure and the side wall panel 40 of the nacelle cover 60 as an example. Herein, the profile structure used to connect with the side wall panel 40 of the nacelle cover 60 is defined as the second profile 20.

[0070] like Figure 2 As shown, the second profile 20 includes a second profile body 210 and a second connecting portion 220 . The second connecting portion 220 is used to connect to the side wall panel 40 .

[0071] like Figure 2 、 Figure 3 and Figure 4 As shown, the second profile body 210 has a third side wall 211 and a fourth side wall 212 disposed opposite each other. The third side wall 211 may have the aforementioned protrusion or recess to cooperate with the recess or protrusion on the first profile 10 to achieve docking of the second profile 20 with the first profile 10 and provide corresponding waterproofing, which will not be described in detail here.

[0072] The third side wall 211 may also have the above-mentioned bolt hole 160 to cooperate with the bolt hole 160 on the second side wall 112 of the first profile 10, and the bolt hole 160 on the third side wall 211 is set on the side of the convex part or the concave part away from the second connecting part 220, that is, away from the side wall panel 40, to prevent the connecting parts passing through the bolt hole 160 from being contaminated by external rainwater.

[0073] Of course, when the second profile 20 is not connected to the first profile 10 , the third side wall 211 may not have the above-mentioned convex or concave portions, bolt holes 160 and other structures.

[0074] As for the connection structure between the second profile 20 and the side wall panel 40, further, as Figure 2 、 Figure 3 and Figure 4As shown, the second connection portion 220 is connected to the edge of the fourth side wall 212 of the second profile body 210 , and the second connection portion 220 is used to be connected to the side wall panel 40 of the nacelle cover 60 .

[0075] As an example, Figure 2 、 Figure 3 and Figure 4 As shown, when the second profile 20 is connected to the side wall panel 40 , the third side wall 211 and the fourth side wall 212 can be distributed up and down so that the second connecting portion 220 is located outside the second profile 20 , which facilitates connection with the side wall panel 40 .

[0076] The portion of the fourth side wall 212 near the second connecting portion 220 is recessed to form a receiving groove 250. The top end of the side wall panel 40 is inserted into the receiving groove 250. This not only facilitates quick positioning of the side wall panel 40 for connection to the second profile 20, but also serves as a position limiter for the side wall panel 40, preventing it from moving significantly and improving the installation stability of the side wall panel 40. Furthermore, in practical applications, because the notch of the receiving groove 250 faces downward, rainwater from the outside cannot enter the interior of the nacelle 60 through the gap between the side wall panel 40 and the second profile 20, thus providing a waterproof function.

[0077] The second connecting portion 220 is provided with a mounting hole 221, and a screw is inserted into the side wall panel 40 through the mounting hole 221 to secure the connection. Of course, the screw can also be replaced with other connecting pieces, such as rivet screws, latches, etc.

[0078] Furthermore, to prevent rainwater from entering the interior of the nacelle cover 60 through the mounting hole 221 on the second connecting portion 220, glue can be applied between the second connecting portion 220 and the side wall panel 40, and glue can be applied around the mounting hole 221. Since the mounting hole 221 is located on the side of the nacelle cover 60, it is unlikely to be directly hit by rainwater, thus maintaining a long-term waterproof effect and being less likely to fail.

[0079] In addition, if Figure 2 、 Figure 3 and Figure 4 As shown, a connection interface 240 for connecting to the internal structure of the nacelle cover 60 may be formed on the fourth side wall 212 of the second profile body 210 , and other profiles or other components may be connected through this connection interface 240 .

[0080] The second profile 20 is connected to the side wall panel 40 of the nacelle cover 60 , thereby increasing the strength of the side wall panel 40 and facilitating the connection between the second profile 20 and the roof panel 30 .

[0081] The profile structure provided by the present invention can be the above-mentioned first profile 10, or the above-mentioned second profile 20, or can include the above-mentioned first profile 10 and second profile 20 at the same time, and the two can be produced and sold in coordination.

[0082] The profile structure can be made of aluminum alloy, which is lightweight and easy to process. The advantages of aluminum alloy pultrusion can be utilized to achieve various functions, such as waterproofing between panels and profiles, connecting the top cover panel 30 and the side wall panels 40, connecting the respective component frames, and providing a waterproof structure to prevent backflow. Of course, the profile structure can also be made of other materials, not limited to aluminum alloy.

[0083] The profile structure and the panel are connected by screws or riveted connections, avoiding the welding structure, preventing weld cracking caused by vibration fatigue of the unit and increasing the reliability of the unit.

[0084] A structural waterproof structure is used between the first profile 10 and the second profile 20. When the top cover panel 30 is hoisted and docked with the side wall panel 40, the joint does not need to be sealed with glue, avoiding the safety risks caused by high-altitude glue application on site.

[0085] The structural waterproofing between the top cover panel 30 and the first profile 10 increases the waterproofing reliability compared to waterproofing relying solely on sealant.

[0086] like Figure 3 、 Figure 4 and Figure 6 As shown, a second embodiment of the present invention provides a nacelle cover 60, which includes a panel and a profile structure as described in any one of the above embodiments.

[0087] The panels of the nacelle cover 60 may include a top cover panel 30, a side wall panel 40 and a bottom cover panel. The profile structure may connect the corresponding panels as needed.

[0088] Furthermore, when the roof panel 30 includes multiple sub-panels, each sub-panel can include multiple single-layer sub-panels and connecting ribs located at both ends of the single-layer sub-panel in the width direction. Two adjacent single-layer sub-panels are butted together via the two connecting ribs to form a large sub-panel. The multiple sub-panels are then connected together to form a complete roof panel 30. One end of the multiple connecting ribs in the length direction can be inserted into the mounting groove 130 of the first profile 10 along with the edge of the sub-panel.

[0089] A third embodiment of the present invention provides a wind turbine generator set, which includes a nacelle cover 60 provided in the second embodiment.

[0090] The wind turbine generator set provided by the embodiment of this aspect has the nacelle cover 60 of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0091] Although the embodiments of the present invention have been described in detail above, those skilled in the art may 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 opinion of those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
