Description

Technical Field

[0001] This application relates to the field of wind power equipment technology, and in particular to a wind turbine nacelle support device. Background Technology

[0002] The nacelle is a key component of a wind turbine generator set, usually located on top of the turbine. The nacelle provides a stable support structure for the various internal equipment, enabling it to operate normally in high-altitude environments. At the same time, the nacelle shell protects the internal equipment from the harsh external environment. The various components inside the nacelle work together to convert the wind energy captured by the rotor into electrical energy through processes such as gearbox speed-up and generator power generation. This electrical energy is then transmitted to the power grid via transmission lines, realizing the conversion and transmission of wind energy into electrical energy.

[0003] Before the wind turbine nacelle is used, it needs to be lifted with hoisting tools. To ensure construction safety, no construction operations can be carried out within a certain range below the wind turbine nacelle after it is lifted. This will affect the work originally planned to be carried out in the construction area (including below the nacelle), directly causing delays in related procedures. The construction personnel, equipment and other resources originally arranged in this area may be idle, resulting in waste of resources and reduced construction efficiency. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0022] The following is a detailed description of the wind turbine nacelle support device through specific embodiments: Reference Figures 1 to 3 As shown in the figure, some embodiments of this application provide a wind turbine nacelle support device, including a base 10, a load-bearing component, a lifting component 30, a support component, and a snap-fit ​​component.

[0023] The supporting component is located above the base 10, and the top surface of the supporting component forms a supporting surface for directly supporting the wind turbine nacelle.

[0024] The lifting assembly 30 is supported between the base 10 and the load-bearing assembly and is configured to lift the load-bearing assembly relative to the base 10 for vertical movement. By setting the lifting assembly 30, a smooth and powerful lifting force can be provided to ensure that the cabin rises and falls slowly and avoids impact.

[0025] The support assembly includes a sleeve 41 and a support 42 movably inserted into the sleeve 41. One of the sleeve 41 and the support 42 is connected to the base 10, and the other is connected to the bearing assembly. The support 42 is provided with a plurality of snap-fit ​​grooves 421 arranged sequentially along the height direction. The snap-fit ​​assembly includes a snap-fit ​​member 51, which is movably disposed on the outside of the sleeve 41 so that it is inserted into the snap-fit ​​groove 421 when it moves toward the snap-fit ​​member 51, and disengaged from the snap-fit ​​groove 421 when it moves away from the snap-fit ​​member 51.

[0026] In other words, after the lifting assembly 30 is activated, the load-bearing assembly gradually rises or falls as needed, causing the support member 42 to gradually extend or retract from the sleeve member 41. When the target height is reached, the lifting assembly 30 is stopped, and then the locking assembly is operated to insert the locking member 51 into the locking slot 421 corresponding to the current height. In this way, the support member 42 is mechanically locked and cannot be retracted. The lifting assembly 30 and the support assembly are jointly supported between the base 10 and the load-bearing assembly. Even if the lifting assembly 30 fails, the load-bearing assembly will not descend. When it is necessary to adjust the nacelle height, the locking assembly is first operated to disengage the locking member 51 from the locking slot 421, and then the lifting assembly 30 is used to control the movement of the load-bearing assembly.

[0027] The entire device is powered for lifting via the lifting component 30, mechanically locked and guided by the support component, and securely locked by the locking component. The coordinated operation of height adjustment and locking is achieved through the linkage between the three components, making it simple and reliable to operate.

[0028] In practice, the wind turbine nacelle support device of this application allows the wind turbine nacelle to be lifted to a certain height, freeing up the space below the nacelle so that construction personnel and equipment can work below the nacelle, avoiding process delays and resource waste. The snap-fit ​​component provides a reliable mechanical locking mechanism to prevent the load-bearing component from falling accidentally, improving safety. The entire device is robust and easy to operate, suitable for construction at wind power generation sites, and effectively solves the problem that the space below the nacelle cannot be utilized during hoisting.

[0029] Specifically, the lifting component 30 can use a hydraulic, mechanical, or pneumatic structure to lift the load-bearing component.

[0030] In some embodiments, a fixing plate 411 and a guide plate 412 are provided on the outer side of the sleeve 41.

[0031] Reference Figure 2 and Figure 3 As shown, the snap-fit ​​component 51 includes a first connecting arm 511 and a snap-fit ​​block 512. One end of the first connecting arm 511 is rotatably connected to the fixing plate 411, and the fixing plate 411 can provide a fulcrum for rotation. The snap-fit ​​block 512 is movably connected to the other end of the first connecting arm 511. One of the snap-fit ​​block 512 and the guide plate 412 is provided with a guide groove 513, and the other is provided with a guide block 413. For example, the guide plate 412 is provided with a guide groove 513, and the snap-fit ​​block 512 is provided with a guide block 413; or, the guide plate 412 is provided with a guide block 413, and the snap-fit ​​block 512 is provided with a guide groove 513.

[0032] The guide block 413 slides in conjunction with the guide groove 513 to guide the snap-fit ​​block 512 as it is inserted into and removed from the snap-fit ​​groove 421. In other words, the guide block 413 and guide groove 513 guide the movement of the snap-fit ​​block 512. It can be understood that when the first connecting arm 511 rotates, it drives the snap-fit ​​block 512 to move. At this time, the guide block 413 slides along the guide groove 513, thereby guiding the snap-fit ​​block 512 to move along a predetermined path, ensuring that the snap-fit ​​block 512 is accurately inserted into or removed from the snap-fit ​​groove 421.

[0033] In practice, when locking the support component is required, the first connecting arm 511 is operated to rotate around the fixed plate 411. The first connecting arm 511 drives the locking block 512 to move towards the support member 42. Under the constraint of relative sliding between the guide block 413 and the guide groove 513, the locking block 512 is inserted into the locking groove 421 in a vertical or near-vertical direction. When the locking block 512 is fully inserted into the locking groove 421, the support member 42 is locked. When unlocking is required, the first connecting arm 511 is operated in reverse, and the locking block 512 disengages from the locking groove 421. The cooperation between the guide groove 513 and the guide block 413 reduces friction and misalignment during the movement of the locking block 512, ensuring smooth operation and avoiding jamming or misoperation.

[0034] Specifically, the first connecting arm 511 and the fixed plate 411 are connected by a rotating shaft 414 to achieve relative rotation. The guide groove 513 can be straight or curved to optimize the movement trajectory of the snap-fit ​​block 512.

[0035] Reference Figure 2 and Figure 3 As shown, the snap-fit ​​component 51 also includes a second connecting arm 514, which is connected to the first connecting arm 511, and the connection between the second connecting arm 514 and the first connecting arm 511 forms a rotation axis that rotates relative to the fixed plate 411; the snap-fit ​​assembly also includes a support column 52 and a drive frame 53 that is slidably disposed on the support column 52 along the height direction, the drive frame 53 being rotatably connected to the second connecting arm 514 so that when the drive frame 53 slides relative to the support column 52, it drives the snap-fit ​​block 512 to move through the first connecting arm 511.

[0036] In other words, the drive frame 53 is slidably mounted on the support column 52 along the height direction, meaning that the drive frame 53 can slide up and down along the support column 52. The drive frame 53 is rotatably connected to the second connecting arm 514, for example, by a pin hinge. When the drive frame 53 slides relative to the support column 52, the second connecting arm 514 can drive the first connecting arm 511 to rotate, thereby driving the locking block 512 to move.

[0037] Specifically, the second connecting arm 514 and the first connecting arm 511 are angled together and form an integral structure.

[0038] For example, when the drive frame 53 slides upward, the second connecting arm 514 pulls the first connecting arm 511, causing the first connecting arm 511 to rotate around the fixed plate 411, thereby driving the locking block 512 to disengage from the locking groove 421. When the drive frame 53 slides downward, it pushes the first connecting arm 511 to rotate in the opposite direction, so that the locking block 512 can move toward the support member 42 and insert into the locking groove 421 to achieve locking.

[0039] In some embodiments, the drive frame 53 has a through hole, the support column 52 passes through the through hole, the through hole is formed as a first threaded hole, and a threaded mating part 521 is formed on the outer side of the support column 52, the threaded mating part 521 is threaded through the first threaded hole.

[0040] When the support column 52 rotates, the drive frame 53 moves up and down along the support column 52 due to the threaded engagement, thereby driving the locking member 51 to move through the second connecting arm 514. It is understood that the threaded transmission provides self-locking capability, meaning that when the support column 52 stops rotating, the drive frame 53 can maintain its position, preventing accidental movement and ensuring high reliability. Furthermore, by converting rotary motion into linear motion, precise control can be achieved.

[0041] Specifically, the support column 52 can be rotatably connected to the base 10 via a bearing. In some embodiments, there are multiple support components. Each support component has a snap-fit ​​component 51 on the outer side of the sleeve 41. The second connecting arm 514 of each snap-fit ​​component 51 is rotatably connected to the drive frame 53. The support column 52 is rotatably connected to the base 10 so that when the support column 52 is driven to rotate, the drive frame 53 drives multiple snap-fit ​​components 51 to move relative to the sleeve 41 at the same time.

[0042] In practice, when the operator rotates the support column 52, the drive frame 53 moves up and down due to the threaded engagement. The movement of the drive frame 53 simultaneously pulls or pushes all the second connecting arms 514, thereby driving all the locking parts 51 to move synchronously through their respective first connecting arms 511. That is, all the locking parts 51 can be inserted into or withdrawn from their respective locking slots 421 at the same time, realizing the synchronous locking or unlocking of all support components, ensuring that the load-bearing components are locked evenly, avoiding uneven loads, and at the same time reducing operation time and manpower, improving work efficiency and safety.

[0043] Understandably, multiple second connecting arms 514 are connected to the drive frame 53 respectively. Under the condition that the position of the support component is fixed, the rotation of the support column 52 can be directly converted into the up and down movement of the drive frame 53, avoiding additional rotation, improving the accuracy of the locking operation, and avoiding the locking effect being affected by the incomplete displacement of the locking block 512.

[0044] In some embodiments, the first connecting arm 511 has a relief groove 515 on the side facing the snap-fit ​​block 512, and the relief groove 515 extends along the extension direction of the first connecting arm 511. For example, the relief groove 515 is an elongated groove formed on the first connecting arm 511. The snap-fit ​​block 512 has a positioning post 516 on the side facing the first connecting arm 511. The positioning post 516 is slidably disposed in the relief groove 515, and the positioning post 516 is rotatably engaged with the groove wall of the relief groove 515.

[0045] When the first connecting arm 511 rotates, the locking block 512 can be driven to move through the cooperation of the clearance groove 515 and the positioning post 516. At the same time, the clearance groove 515 allows the positioning post 516 to slide and rotate, thereby adapting to the position change of the locking block 512 during the movement. With the cooperation of the guide groove 513 and the guide block 413, the locking block 512 and the positioning post 516 can be adaptively adjusted within a certain angle to ensure that the locking block 512 can be smoothly inserted into the locking groove 421, reducing the wear between the locking block 512 and the locking groove 421, improving the smoothness of operation and reducing assembly errors.

[0046] In some embodiments, refer to Figure 1As shown, the load-bearing assembly includes a base 21 and a load-bearing platform 22 mounted on the base 21. The top surface of the load-bearing platform 22 is formed as a load-bearing surface, which is formed as an arc-shaped surface to match the curved contour of the nacelle, ensuring large-area contact and reducing local pressure. Anti-slip pads 221 are attached to the load-bearing surface to increase the coefficient of friction, prevent the nacelle from shifting under wind or vibration, and enhance safety.

[0047] Specifically, there are two support platforms 22, and at least one support platform 22 is slidably connected to the base 21 to achieve relative proximity or relative distance. That is, the support platform 22 can slide relative to the base 21 to achieve relative proximity or distance between the two support platforms 22, and the other support platform 22 may be fixedly connected to the base 21 or also slidably connected.

[0048] Understandably, the sliding support platform 22 design allows the device to adapt to wind turbine nacelles of different sizes, improving the device's versatility and flexibility. The adjustment mechanism of the support platform 22 is simple, reducing the time required to change tooling and improving construction efficiency.

[0049] Reference Figure 1 As shown, a guide post 211 is provided on the base 21, and a first through hole is provided on the support platform 22. The guide post 211 slides through the first through hole. A drive motor 212 and a drive rod 213 are also provided on the base 21. The drive motor 212 drives the drive rod 213 to rotate relative to the base 21. A second through hole is provided on the support platform 22. A first threaded portion 214 and a second threaded portion 215 are formed on the outer side of the drive rod 213. The first threaded portion 214 is threaded through the second through hole of one of the support platforms 22, and the second threaded portion 215 is threaded through the second through hole of the other support platform 22. The thread directions of the first threaded portion 214 and the second threaded portion 215 are opposite.

[0050] Specifically, the base 21 includes a base plate 216 and two side plates 217 disposed on opposite sides of the base plate 216. The support platform 22 is located between the two side plates 217. The guide column 211 and the drive rod 213 can rotate relative to the side plates 217 through bearings and other structures.

[0051] When the drive motor 212 starts, it drives the drive rod 213 to rotate. Due to the opposite thread direction, the two support platforms 22 move closer or further apart along the guide post 211 (depending on the rotation direction of the drive rod 213). The guide post 211 ensures the linear movement of the support platforms 22 and avoids jamming. The movement of the two support platforms 22 can be synchronously controlled by one drive rod 213. Precise spacing adjustment can be achieved through the electric control of the controller 70. After the adjustment is in place, the drive motor 212 stops, and the relative position between the two support platforms 22 is maintained by the thread self-locking mechanism.

[0052] In some embodiments, the wind turbine nacelle support device further includes an adjustment assembly; the adjustment assembly includes a bottom support plate 61 and a threaded rod 62. The bottom support plate 61 is used to support the ground in the construction area to increase the support area and ensure support stability. The threaded rod 62 is disposed on the top surface of the bottom support plate 61, and a second threaded hole is provided on the base 10, through which the threaded rod 62 is threaded. It is understood that, under uneven ground conditions, the base 10, by providing the adjustment assembly, can be leveled to adapt to ground undulations, reducing the risks caused by uneven loads and improving safety and adaptability.

[0053] Specifically, refer to Figure 1 As shown, when the height of the base 10 needs to be adjusted, the threaded rod 62 is rotated. Due to the threaded engagement, the base 10 rises or falls relative to the bottom support plate 61. Each corner of the base 10 is equipped with an adjustment component. By adjusting each threaded rod 62 individually, the base 10 can be adjusted horizontally. After adjustment, the position of the threaded rod 62 can be fixed by tightening the lock nut.

[0054] Furthermore, the bottom of the bottom support plate 61 is provided with a pad made of rubber or polyurethane material to increase friction and prevent slippage.
