[0035] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0036] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the outline of the corresponding component. In addition, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0037] according to Figures 1 to 4 As shown, the first aspect of the present disclosure provides a hanging hole cover structure for the nacelle hanging hole 5 of a wind turbine generator system, which can realize the opening and closing of the nacelle hanging hole 5. The hanging hole cover structure may include a fixed bracket 1 and a hanging hole cover 4. The fixed bracket 1 may include a connecting portion 6 for connecting to the circumference of the nacelle hanging hole 5, and a sliding portion 3 extending along a first direction X. The hanging hole cover 4 is slidably connected to the sliding portion 3. The hanging hole cover 4 has a first position for covering the nacelle hanging hole 5 and a second position for opening the nacelle hanging hole 5. The hanging hole cover 4 can switch between the first position and the second position.

[0038] Through the above technical solution, the hanging hole cover 4 is slidably connected to the sliding portion 3 of the fixed bracket 1, so that the hanging hole cover 4 can close the cabin hanging hole 5 when it is moved to the first position, and open the cabin hanging hole 5 when it is moved to the second position. As a result, the hanging hole cover 4 can be quickly installed and removed, effectively reducing time costs and providing greater convenience.

[0039] The first position may be any suitable position above the cabin hanging hole 5, as long as the hanging hole cover 4 can be combined with the fixing bracket 1 to block the cabin hanging hole 5; the second position may be any suitable position away from the cabin hanging hole 5, as long as it does not block the cabin hanging hole 5. This disclosure does not make any specific restrictions on this.

[0040] Since the nacelle of a wind turbine is usually set at a high altitude, for example, 70 meters above the ground, the wind is strong at high altitude, and the wind turbine inevitably vibrates during operation, causing the nacelle cover made of fiberglass to deform to varying degrees, resulting in a gap between the hanging hole cover 4 and the nacelle cover. The hanging hole cover 4 cannot fit tightly with the nacelle cover to close the nacelle hanging hole 5. In windy weather, the hanging hole cover 4 will fall into the inside of the nacelle cover and fall to the ground when the wind is strong, causing a safety hazard.

[0041] Therefore, in order to further enhance the stability of the hanging hole cover 4, in some practicable ways, for example, referring to Figure 2 and Figure 3 As shown, the sliding portion 3 may include a first groove 30 and a second groove 31 extending along a first direction X and arranged at intervals along a second direction Y perpendicular to the first direction X. The hanging hole cover 4 is slidably connected to the first groove 30 and the second groove 31 on opposite sides along the second direction Y, so that the hanging hole cover 4 can slide along the first direction X to open and close the cabin hanging hole 5. The hanging hole cover 4 located in the first groove 30 and the second groove 31 can better reduce the adverse effects of strong wind.

[0042] The structure of the sliding portion 3 can be adaptively adjusted according to actual needs. For example, the sliding portion 3 can further include two slide rails extending along the first direction X and arranged opposite to each other along a second direction Y perpendicular to the first direction X. The hanging hole cover 4 is slidably connected to the two slide rails along opposite sides in the second direction Y. The present disclosure is not limited thereto.

[0043] In some embodiments, for example, referring to Figures 2 to 4 As shown, the fixed bracket 1 can also include a third groove 32, the two ends of the third groove 32 are respectively connected to one end of the first groove 30 and the second groove 31 along the first direction X, so that the first groove 30 and the second groove 31 can form an opening 33 on the side away from the third groove 32, and the hanging hole cover 4 can close the cabin hanging hole 5 through the in-and-out opening 33; the fixed bracket 1 can also include a rectangular bracket body 10 arranged around the circumference of the cabin hanging hole 5, and a limiting bracket 2 connected to the top of the rectangular bracket body 10, the limiting bracket 2 and the upper end of the rectangular bracket body 10 together form the first groove 30, the second groove 31 and the third groove 32, the rectangular bracket body 10 is used to support the hanging hole cover 4, and the limiting bracket 2 is used to limit the hanging hole cover 4 to only be able to enter and exit the first groove 30, the second groove 31 and the third groove 32 through the opening 33, and further enhance the stability of the hanging hole cover 4.

[0044] The rectangular bracket body 10 and the limiting bracket 2 can be connected in any suitable manner. For example, the rectangular bracket body 10 and the limiting bracket 2 can be constructed as an integrally formed structure to reduce the processing process. The rectangular bracket body 10 and the limiting bracket 2 can also be connected by welding. This disclosure does not specifically limit this.

[0045] Optionally, the limiting bracket 2 may include a first plate 20 extending in a vertical direction perpendicular to the first direction X, and a second plate 21 arranged perpendicular to the first plate 20. The first plate 20 is connected to the top of the rectangular bracket body 10, and the second plate 21 is used to limit the movement of the hanging hole cover 4 in the vertical direction to prevent the hanging hole cover 4 from being lifted off to the inside of the cabin when the wind is strong, which is safer and more stable.

[0046] In some embodiments, for example, referring to Figures 1 to 2 As shown, the connecting portion 6 may include a support 60 connected to the outer side wall of the fixing bracket 1, and the support 60 is detachably connected to the nacelle shell 8 through a first fastener 61. The detachable manner facilitates the operator to replace and maintain the fixing bracket 1.

[0047] The structure of the support 60 can be adaptively adjusted according to actual needs. For example, the support 60 can be configured as an L-shaped connecting plate with a through hole, and the first fastener 61 can be configured as a connecting bolt connected to the cabin shell 8 through the through hole. The present disclosure is not limited thereto.

[0048] The number of supports 60 can be adaptively adjusted according to actual needs. For example, the number of supports 60 can be eight, and the eight supports 60 are respectively arranged around the circumference of the fixed bracket 1. The number of supports 60 can also be twelve. This disclosure does not make specific limitations on this.

[0049] In some embodiments, for example, referring to Figure 1 As shown, a handle 40 may also be provided on the hanging hole cover 4 to facilitate the operator to operate the hanging hole cover 4.

[0050] In some embodiments, for example, referring to Figure 1 and Figure 2 As shown, the outer wall of the fixed bracket 1 can also be provided with a locking member 7, which is configured to lock and fix the hanging hole cover 4 when the hanging hole cover 4 moves to the first position to prevent the hanging hole cover 4 from moving to the second position due to non-human factors.

[0051] The structure of the locking member can be adaptively adjusted according to the needs of actual conditions. For example, the locking member 7 may include a fixing seat 70 with a mounting hole and a second fastener 71. The fixing seat 70 is connected to the side wall of the fixing bracket 1 and is located at the opening 33 of the fixing bracket 1. The second fastener 71 is used to cooperate with the mounting hole to achieve the fixation of the second fastener 71 and enable the second fastener 71 to limit the hanging hole cover 4. The locking member 7 can also be constructed as a mounting plate. The mounting plate and the fixing bracket 1 are both provided with corresponding mounting holes. The second fastener 71 is used to connect the mounting plate and the fixing bracket to close the opening 33 and limit the movement of the hanging hole cover 4 to the second position. The second fastener 71 can be constructed as a connecting bolt or a latch, and the mounting hole can be constructed as a threaded hole. The present disclosure is not limited to this.

[0052] According to a second aspect of the present disclosure, a cabin cover is provided, comprising a cabin shell 8 and a hanging hole cover structure, wherein a cabin hanging hole 5 is provided on the cabin shell 8, and the hanging hole cover structure is provided at the cabin hanging hole 5. The hanging hole cover structure has all the beneficial effects of the above-mentioned specific embodiments, which will not be repeated in this disclosure.

[0053] Optionally, the cabin hanging hole 5 can be located at the bottom of the cabin shell 8 to facilitate the transportation of materials.

[0054] The present disclosure exemplarily describes the installation process of the hanging hole cover structure. For example, the connecting portion 6 of the fixing bracket 1 is fixed to the circumference of the cabin hanging hole 5 by connecting bolts. After the fixing is completed, sealant can be applied to the contact surface between the fixing bracket 1 and the cabin shell 8 to further reinforce it. Subsequently, the hanging hole cover 4 is pushed into the first groove 30 and the second groove 31 from the opening 33 of the fixing bracket 1, and moved along the first groove 30 and the second groove 31 to the third groove 32. When the hanging hole cover 4 completely covers the cabin hanging hole 5, the opening 33 is closed by the locking member 7 to limit the movement of the hanging hole cover 4, and the installation is completed.

[0055] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments.
