[0002] In the field of wind power technology, the precise installation and calibration of wind vanes are crucial for ensuring the accuracy of the turbine's windward angle and thus optimizing power generation efficiency. The adjusting sleeve at the bottom of the wind vane is mounted on a fixed stake, and its circumferential position is typically adjusted by the operator directly rotating the sleeve. This traditional method has significant drawbacks: low adjustment accuracy and a tendency to produce large deviations. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a wind turbine wind vane fine adjustment device to solve the problems of low adjustment accuracy and large deviation in the existing technology.

A scale is provided on the fixed frame, and the movement direction of the scale corresponds to that of the indicator. The rotating part and the top of the adjusting sleeve are rotatably connected, and a wind vane is fixedly disposed on the top of the rotating part. The working principle of this utility model is as follows: This utility model moves the end of the telescopic rod, thereby driving the adjusting sleeve to rotate. The end of the telescopic rod can be precisely controlled to move along the screw axis.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] like Figure 1As shown, a wind turbine wind vane fine-tuning device includes a fixed frame 4, a screw 5, a fixed stake 3, a telescopic rod 12, an adjusting sleeve 2, an indicator 13, and a rotating part. The fixed frame 4 is fixedly connected to the side of the fixed stake 3. The screw 5 is horizontally disposed on one side of the fixed stake 3, and both ends of the screw 5 are rotatably connected to the fixed frame 4. The indicator 13 is slidably connected to the screw 5. The adjusting sleeve 2 is rotatably connected to the top of the fixed stake 3, and directional marks are provided on opposite sides of the adjusting sleeve 2. One end of the telescopic rod 12 is fixedly connected to the adjusting sleeve 2, and the other end of the telescopic rod 12 is hinged to the indicator 13. A scale is provided on the fixed frame 4, and the movement direction of the scale corresponds to that of the indicator 13. The rotating part is rotatably connected to the top of the adjusting sleeve 2, and a wind vane 1 is fixedly disposed on the top of the rotating part.

[0020] Operating Procedure: The operator pushes the telescopic rod 12 from the end furthest from the adjusting sleeve 2, causing the indicator 13 to slide along the screw 5. When the indicator 13 aligns with the midpoint of the scale on the fixed frame 4, it indicates that the circumferential position of the adjusting sleeve 2 has been adjusted to the correct orientation. By finely moving the telescopic rod 12 from the operating end furthest from the adjusting sleeve 2, the displacement of the indicator 13 can be precisely controlled, thereby achieving fine adjustment of the rotation angle of the adjusting sleeve 2.

[0021] Preferably, the indicator 13 includes a sliding sleeve 7 and a pointer 6 fixed to the outer wall of the sliding sleeve 7 and extending downward. The sliding sleeve 7, with the help of the downward-extending pointer 6, improves the accuracy of the scale reading.

[0022] Preferably, the screw 5 is provided with locking nuts 11 at both ends for limiting the position of the indicator 13. The locking nuts 11 securely lock the indicator 13, effectively preventing it from being accidentally displaced due to vibration or external force during use.

[0023] Preferably, both ends of the screw 5 are threadedly connected to the fixing frame 4, and the end of the screw 5 is provided with a rotation groove 10. The groove 10 at the end of the screw 5 facilitates fine-tuning using standard tools, improving the ease of operation.

[0024] Preferably, the fixing bracket 4 is provided with a rotation scale at the end of the screw 5. The rotation scale converts the number of rotations into an intuitive and quantifiable reading, making the adjustment process more precise rather than empirical.

[0025] Preferably, the telescopic rod 12 includes a fixed sleeve 8 and a sliding rod 9, which are coaxial and slidably connected. The free end of the fixed sleeve 8 is fixedly connected to the adjusting sleeve 2, and the free end of the sliding rod 9 is hinged to the sliding sleeve 7.

[0026] Preferably, the orientation markings include S and N. In this embodiment, S faces the wind turbine rotor and is perpendicular to the rotor's rotation surface.

[0027] Preferably, a connecting bearing is provided between the rotating part and the adjusting sleeve 2. The connecting bearing makes the rotation between the rotating part and the adjusting sleeve 2 smoother and more flexible, effectively reducing friction loss and operating resistance.

[0028] Preferably, the telescopic rod 12 is provided with screws for locking the relative position of the fixing sleeve 8 and the sliding rod 9.

[0029] Preferably, the adjusting sleeve 2 and the fixed pile 3 are rotatably connected by a thrust ball bearing.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
