Description
Technical Field
[0001] This utility model relates to the field of stator support installation technology, specifically an adjustable support base for offshore wind power stator supports. Background Technology
[0002] The stator support serves as the "skeleton" of the generator, fixing the stator core (including windings) at one end and connecting the base (such as a tower or floating platform) at the other end to ensure that the generator maintains a stable position during operation. For example, in floating wind power, the support needs to buffer the vibration caused by waves through flexible connections or damping devices to avoid efficiency reduction due to changes in the air gap between the stator and rotor. In offshore wind power equipment, the support base of the stator bracket needs to be adapted to the special humid environment at sea, while also meeting the height adjustment function. At present, the industry generally adopts a structure with screw and threaded sleeve connection to drive the support arm, thereby realizing the height adjustment of the support base. However, the high humidity and high salt spray environment at sea can easily aggravate the wear and corrosion of the screw and sleeve, seriously affecting the service life and operational stability of the regulating mechanism. To alleviate this problem, the existing technology usually uses the method of regularly applying lubricating oil to the mating surface of the screw and sleeve for protection. However, due to the limited space formed after the support arm is installed, this operation is not only time-consuming and laborious, but also difficult to evenly apply the lubricating oil to the entire thread mating surface, greatly reducing the protective effect and causing many inconveniences to the daily maintenance of the equipment. Therefore, an adjustable support base for offshore wind turbine stator supports is proposed to address the above problems. Utility Model Content

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: An adjustable support base for an offshore wind turbine stator includes a support platform 1. Oil storage support seats 2 are fixed to both sides of the upper surface of the support platform 1. A self-lubricating support arm mechanism 3 is installed inside the oil storage support seat 2. The tops of the two self-lubricating support arm mechanisms 3 are mounted on the same bearing platform 4. Each self-lubricating support arm mechanism 3 includes a connecting seat 31. A support arm 32 is hinged to the inner side of the connecting seat 31. An adjusting arm 33 is hinged to one end of the support arm 32. A first connecting seat 34 slides along the top of the adjusting arm 33 via a connecting shaft. A first threaded sleeve 35 is hinged to the bottom end of the first connecting seat 34. The inner side of the first threaded sleeve 35 is threaded... A screw mechanism 36 is connected, and a drive mechanism 37 is installed at one end of the screw mechanism 36. A second connecting seat 38 is fixed below the first screw sleeve 35. A maintenance rod mechanism 39 is rotatably connected to the inner side of the second connecting seat 38. The maintenance rod mechanism 39 includes a second screw sleeve 391. Both ends of the outer side of the second screw sleeve 391 are fixed with stirring blades 392. A fiber brush sleeve 393 is fixed to the back of the stirring blades 392. A connecting screw 394 is threadedly connected to the inner side of the second screw sleeve 391. A ball connecting rod 395 is fixed to one end of the connecting screw 394 through a telescopic rod. A storage sleeve 396 is sleeved on the other end of the connecting screw 394.
[0017] As a further implementation of this solution, the screw mechanism 36 includes a screw body 361, with drive shafts 362 fixed at both ends of the screw body 361. The axis of the drive shafts 362 and the axis of the screw body 361 are located on the same central axis. The two drive shafts 362 are rotatably connected to both ends of the inner side of the oil storage support 2, and a connecting sleeve 363 is fixed at one end of one of the drive shafts 362. Specifically, the screw body 361 and the oil storage support 2 are stably connected by the drive shaft 362, ensuring the stability and reliability of the screw body 361 when rotating. The connecting sleeve 363 provides a connection point for the drive mechanism 37, so that the drive mechanism 37 can effectively drive the screw body 361 to rotate, thereby accurately adjusting the height of the support base. As a further implementation of this solution, the drive mechanism 37 includes a guide rod 371, a support spring 372 is sleeved on the outside of the guide rod 371, an external hexagonal drive rod 373 is fixed to one end of the guide rod 371, a drive wheel 374 is fixed to one end of the external hexagonal drive rod 373, and a circular rail 375 is fixed to the back of the drive wheel 374. Specifically, through the elastic force of the support spring 372, the external hexagonal drive rod 373 can be separated from the connecting sleeve 363 in its natural state to avoid misoperation. When the height needs to be adjusted, an external force is applied to the drive wheel 374 to compress the spring and make the external hexagonal drive rod 373 engage with the connecting sleeve 363 to drive the screw mechanism 36. The circular rail 375 provides the power transmission basis for the subsequent operation of the maintenance rod mechanism 39. As a further implementation of this solution, the other end of the guide rod 371 is slidably connected to the center of the inner side of the connecting sleeve 363. The shape of the inner side of the connecting sleeve 363 is adapted to the shape of the outer side of the hexagonal drive rod 373, and the hexagonal drive rod 373 and the connecting sleeve 363 are inserted into each other. Specifically, the guide rod 371 slides within the connecting sleeve 363, allowing the external hexagonal drive rod 373 to be accurately inserted into the connecting sleeve 363, forming a reliable rigid connection. This effectively prevents slippage or misalignment during the drive process, ensuring smooth height adjustment. As a further implementation of this scheme, the two stirring blades 392 are symmetrically distributed from left to right. The stirring blades 392 are located below the screw body 361, and there is a gap between the stirring blades 392 and the screw body 361. The fiber brush sleeve 393 is attached to the screw body 361. Specifically, the symmetrical distribution design of the stirring blades 392 can evenly stir the lubricating oil in the oil storage support 2 when rotating, improve the fluidity of the lubricating oil, and enable it to better perform its lubricating function. The fiber brush sleeve 393 fits into the screw body 361, which can evenly apply the stirred lubricating oil to the screw body 361, effectively protecting the threaded mating surface between the screw body 361 and the first screw sleeve 35, reducing wear and corrosion, and extending the service life of the support base. As a further implementation of this solution, the connecting screw 394 is located below the screw body 361, and extends to the outside of one end of the oil storage support 2. One end of the spherical connecting rod 395 is rotatably engaged with the inner side of the circular rail 375. The storage sleeve 396 extends to the outside of the other end of the oil storage support 2 and is fixedly connected to the oil storage support 2. The axis of the storage sleeve 396 and the axis of the connecting screw 394 are located on the same central axis. The storage sleeve 396 is responsible for positioning and storing the connecting screw 394. As a further implementation of this solution, the bottom end of the connecting seat 31 is fixedly connected to one side of the upper surface of the oil storage support seat 2, and the upper surface of the first connecting seat 34 is fixedly connected to the lower surface of the bearing platform 4. Specifically, this ensures that the height adjustment action of the self-lubricating support arm mechanism 3 can be accurately transmitted to the bearing platform 4, thereby achieving precise adjustment of the stator support height.
[0018] Workflow: The support platform 1 is placed securely in the predetermined position. The oil storage support 2 is fixed on both sides of the upper surface of the support platform 1. The interior is filled with sufficient lubricating grease and is higher than the screw mechanism 36. All components of the self-lubricating support arm mechanism 3 are in the initial position. The support spring 372 in the drive mechanism 37 is in the natural state. The external hexagonal drive rod 373 is not in contact with the connecting sleeve 363. The maintenance rod mechanism 39 is in the standby state. The bearing platform 4 is placed above the self-lubricating support arm mechanism 3 to provide support for the stator bracket. When it is necessary to adjust the height of one side of the stator support, an external force is applied to the drive wheel 374. The drive wheel 374 drives the external hexagonal drive rod 373 and the guide rod 371 to move synchronously. The support spring 372 contracts, so that the external hexagonal drive rod 373 is inserted into the connecting sleeve 363 to form a rigid connection. The drive wheel 374 continues to rotate, and drives the connecting sleeve 363 to rotate through the external hexagonal drive rod 373. The connecting sleeve 363 drives the screw body 361 to rotate synchronously through the transmission shaft 362. Since the screw body 361 is threadedly connected to the first screw sleeve 35, the first screw sleeve 35 slides along the inner side of the oil storage support 2, thereby changing the tilt angle of the adjusting arm 33. The adjusting arm 33 drives the bearing platform 4 to move up and down through the first connecting seat 34, thereby adjusting the height of the bearing platform 4 on the target side, and thus adjusting the height of the stator support on that side. During the process of the drive wheel 374 rotating and driving the external hexagonal drive rod 373 to insert into the connecting sleeve 363, the drive wheel 374 applies pressure to the spherical connecting rod 395 through the circular rail 375. The spherical connecting rod 395 pushes the connecting screw 394 to extend into the inner side of the second threaded sleeve 391. Since the second threaded sleeve 391 is threadedly connected to the connecting screw 394, the second threaded sleeve 391 rotates rapidly around the second connecting seat 38 as the center, driving the stirring blade 392 and the fiber brush sleeve 393 to rotate synchronously. The stirring blade 392 stirs the lubricating oil in the oil storage support seat 2 to improve the fluidity of the lubricating oil. The fiber brush sleeve 393 evenly coats the lubricating oil on the rotating screw body 361, achieving effective protection for the screw body 361 and the first threaded sleeve 35. During the height adjustment process of the drive wheel 374, the drive wheel 374 drives the circular rail 375 to rotate. The circular rail 375 and the spherical connecting rod 395 rotate in coordination, which will not cause motion interference to the maintenance rod mechanism 39. At the same time, since the spherical connecting rod 395 will not disengage from the limit of the circular rail 375, when the first threaded sleeve 35 moves, the second connecting seat 38 below moves synchronously with the first threaded sleeve 35. The second connecting seat 38 drives the second threaded sleeve 391 to move synchronously. When the movement is close to or away from the drive mechanism 37, pressure will be applied to the connecting screw 394, causing the second threaded sleeve 391 to rotate, thereby ensuring the continuous operation of the stirring blade 392 and the fiber brush sleeve 393. During adjustment, continuous lubrication protection can be provided for the screw body 361 and the first threaded sleeve 35. After the height adjustment is completed, the external force on the drive wheel 374 is released, the support spring 372 returns to its natural state, and the external hexagonal drive rod 373 separates from the connecting sleeve 363 under the elastic force of the support spring 372. At this time, the bearing platform 4 remains at the adjusted height, providing stable support for the stator bracket.
