[0002] A wind turbine generator set includes a frame, a wind turbine main shaft, a main shaft bearing seat, a wind rotor, and a nacelle. In the prior art, the nacelles of some early wind turbines had design issues, with a small distance between the front of the nacelle and the main shaft wind rotor, and the front of the nacelle was similar to a flat plate structure, resulting in poor rigidity. After long-term use, the front nacelle deformed inward. Furthermore, the nacelle was connected to the frame using elastic supports, and the frame itself had a certain backward tilt angle. After long-term operation, the front of the nacelle easily interfered with the wind rotor, causing wear on the nacelle. This not only reduced the service life of the equipment but also posed a safety hazard. Utility Model Content

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, an auxiliary support device for a wind turbine nacelle cover includes a support frame 1, which is fixedly connected to a fixed object A2.

An adjusting portion for adjusting along the axial direction of the adjusting rod assembly is provided on the adjusting rod assembly, and the adjusting portion abuts against a moving object B3 on a side away from the support frame 1.

[0033] The beneficial effects of this embodiment are: the support frame 1 is fixedly connected to the fixed object A2, and the adjustment part is against the movable object B3, preventing the fixed object A2 and the movable object B3 from being too close, reducing mutual interference and equipment wear; the adjustment part can be moved and adjusted by the adjustment rod assembly, and is suitable for different equipment and different spacings.

[0034] In this embodiment, Figure 3 As shown, the wind turbine unit includes a frame, a wind turbine main shaft, a main shaft bearing seat 16, a wind rotor 17 and a nacelle cover, etc. The frame is located below the wind turbine main shaft, the main shaft bearing seat 16 and the wind rotor 17, and the nacelle cover is located behind the wind rotor 17;

[0035] The fixed object A2 is the frame, and the movable object B3 is the nacelle cover. The nacelle cover is a plate-like structure with poor rigidity. It is easy to deform and interfere with the wind wheel disk 17 after long-term use. Therefore, the support frame 1 is fixed to the frame, and the position of the adjustment part is moved by the adjustment rod assembly. The adjustment part supports the nacelle cover to prevent it from sticking to the wind wheel disk 17 and reduce wear.

[0040] Then screw the second nut 7 onto the screw rod 4, and then insert the adjusting part. One end of the adjusting part rests on the second nut 7, and the other end rests on the nacelle cover. The adjusting part can slide to the position where the second nut 7 is screwed, thereby realizing the adjustment of the adjusting part.

[0041] In addition, the threaded connection has a certain self-locking property, the friction force of the threaded contact surface is large, and the first nut 6 and the second nut 7 are not easily moved by force.

[0042] In addition, the anti-loosening nut 14 can be pressed against the first nut 6 or the second nut 7. When any one of the nuts is tightened, the nut can be tightened to prevent loosening.
