Description

Technical Field

[0001] This utility model belongs to the field of wind power generation equipment, and in particular relates to a wind turbine yaw detection device. Background Technology

[0002] During operation, wind turbines require constant adjustments to the nacelle to align with the changing wind direction, maximizing wind energy capture and increasing power generation efficiency. The device used to adjust the turbine's direction is called the yaw system. To ensure accurate operation, anemometers and wind vanes are typically used to collect wind speed and direction data. This information is then processed by a controller to drive the yaw system. Commonly used yaw detection devices include anemometers, wind vanes, and controllers. Anemometers and wind vanes are usually installed outside the nacelle. When the nacelle rotates with the wind, the anemometers and wind vanes move with the nacelle, making it difficult to maintain a horizontal position. Anemometers and wind vanes in a non-horizontal state may have inaccurate readings. Prolonged periods without a horizontal position increase shaft wear, affecting rotational stability and increasing the risk of instrument malfunction. During power generation, the wind turbine itself generates significant vibrations, which can cause inaccurate measurements, loose or broken internal wiring, and reduced instrument lifespan for yaw detection instruments fixed to the nacelle. Utility Model Content

[0003] The purpose of this utility model is to provide a wind turbine yaw detection device to solve the problems of commonly used wind turbine yaw detection devices, including anemometers, wind vanes, and controllers. Anemometers and wind vanes are usually installed outside the nacelle. When the nacelle rotates with the wind, the anemometers and wind vanes will move with the nacelle and are difficult to keep in a horizontal position. The detection values ​​of anemometers and wind vanes in a non-horizontal state may be affected, resulting in inaccurate detection results. Moreover, the inability to maintain a horizontal rotation for a long time will increase the wear of the shaft, affect the rotational stability, and increase the risk of instrument failure. During the power generation process, the wind turbine itself will generate a lot of vibration, which will cause inaccurate measurement accuracy, loose or broken internal wiring, and affect the service life of the yaw detection instrument fixed on the nacelle.

[0004] To achieve the above objectives, the specific technical solution of this utility model for a wind turbine yaw detection device is as follows:

[0005] A wind turbine yaw detection device includes a tower; a nacelle is rotatably mounted on the top of the tower; a wind turbine is rotatably mounted on one side of the nacelle; a power generation device is installed inside the nacelle; a yaw system is installed at the connection between the nacelle and the tower; the yaw system includes drive motors installed on both sides of the power generation device; a fixed gear is fixedly mounted on the top of the tower; the output shaft of the drive motor is provided with a meshing connection between the drive gear and the fixed gear; a mounting platform is installed on the top of the nacelle; multiple threaded posts are fixedly mounted on the mounting platform; a mounting plate is slidably mounted between the multiple threaded posts; an adjusting wheel is threadedly connected to the threaded posts on the underside of the mounting plate; a spring is installed between the adjusting wheel and the mounting plate on the outside of the threaded posts; a column extends upward from the middle of the mounting plate; an anemometer is rotatably mounted on the upper part of the column; a wind vane is rotatably mounted on the top of the column; a rotating shaft extends rotatably from the wind vane into the column and into the nacelle; a controller is installed on one side of the rotating shaft inside the nacelle.

[0006] Furthermore, the central axis of the column coincides with the central axis of the tower and the nacelle rotational configuration.

[0007] Furthermore, the mounting plate is provided with multiple levels at equal intervals around its circumference.

[0008] Furthermore, a rotating wheel is provided at the bottom of the rotating shaft; three different color display areas are provided on the outer side of the rotating wheel; and a color sensor is provided on the controller facing the rotating wheel.

[0009] This utility model discloses a wind turbine yaw detection device with the following advantages: An installation platform and multiple threaded columns are provided on the top of the nacelle. An installation plate is slidably mounted on these columns, and adjustable wheels support the plate. Adjusting the height of the installation plate at different positions ensures the columns and the anemometer and wind vane mounted on them are horizontal, guaranteeing stable operation and accurate detection of wind direction and speed data. Springs between the adjusting wheels and the installation plate filter and reduce vibrations generated by the wind turbine during power generation, minimizing their impact on the anemometer and wind vane, increasing instrument lifespan, and ensuring accurate detection results. By aligning the central axis of the column with the central axis of the tower and nacelle rotation, the installation platform, installation plate, and column rotate together with the nacelle while the nacelle rotates on the tower using a drive motor, but the central axis of the column remains aligned with the tower and nacelle. The nacelle's rotation is designed with the central axis aligned, ensuring that its rotation does not affect the horizontal accuracy of the anemometers and wind vanes mounted on the column, thus preventing nacelle movement from disrupting their stable operation. Multiple levels are equidistantly positioned around the mounting plate, allowing for easy observation of the plate's horizontal position during height adjustments using the adjusting wheels. Adjusting the column to a vertical position ensures the anemometers and wind vanes remain horizontal, making operation simple and convenient. The anemometers and wind vanes detect wind speed and direction data, which are then processed by the controller. This information is used to control the drive motor to rotate the nacelle and adjust the wind turbine wheel to align with the wind direction. Simultaneously, the rotation of the wind vane drives the rotating shaft to rotate the wheel. Changing the color display area of ​​the relative color sensor further alerts the controller, which in turn drives the nacelle to rotate and adjust the wind turbine wheel. These two alert methods operate synchronously, increasing the stability of the wind turbine yaw detection device. Attached Figure Description

[0017] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a wind turbine yaw detection device.

[0018] like Figure 1-6 As shown, this utility model discloses a wind turbine yaw detection device, including a tower 1; a nacelle 2 is rotatably mounted on the top of the tower 1; a wind turbine 3 is rotatably mounted on one side of the nacelle 2; a transmission and power generation device 4 is installed inside the nacelle 2; a yaw system 5 is installed at the connection position between the nacelle 2 and the tower 1; the yaw system 5 includes drive motors 6 installed on both sides of the transmission and power generation device 4; a fixed gear 7 is fixedly mounted on the top of the tower 1; a drive gear 8 is installed on the output shaft of the drive motor 6, and the drive gear 8 is meshed with the fixed gear 7; a mounting platform 9 is installed on the top of the nacelle 2; and multiple [unclear - possibly referring to a specific type of device] are fixedly mounted on the mounting platform 9. Threaded column 10; mounting plate 11 is slidably arranged between multiple threaded columns 10; adjusting wheel 12 is provided on the lower side of the mounting plate 11 via threaded connection to the threaded column 10; spring 13 is provided on the outside of the threaded column 10 between the adjusting wheel 12 and the mounting plate 11; column 14 is provided extending upward from the middle of the mounting plate 11; an anemometer 15 is rotatably arranged on the upper part of the column 14; wind vane 16 is rotatably arranged at the top of the column 14; a rotating shaft 17 is rotatably arranged extending from the wind vane 16 into the column 14 and into the nacelle 2; a controller 18 is provided on one side of the rotating shaft 17 in the nacelle 2.

[0019] Combination Figure 1-6As shown, during operation, wind speed and direction data are detected by the anemometer 15 and wind vane 16 installed on the column 14 at the top of the nacelle 2. The information is then processed by the controller 18. When the wind direction changes, the controller 18 controls the start of the drive motor 6. The drive gear 8 on the output shaft of the drive motor 6 meshes with the fixed gear 7 at the top of the tower 1, driving the nacelle 2 to rotate on the tower 1 and adjusting the direction of the wind turbine 3 to align with the wind direction, thereby maximizing wind energy capture and increasing power generation efficiency. The nacelle 2 is equipped with a mounting platform 9 and multiple threaded columns 10 at the top. The mounting plate 11 is slidably mounted on the multiple threaded columns 10 and supported by the adjusting wheel 12. By adjusting the adjusting wheel 12, the height of the mounting plate 11 at different positions is adjusted so that the column 14 and the anemometer 15 and wind vane 16 mounted on it are in a horizontal state, ensuring the stable operation of the anemometer 15 and wind vane 16 and ensuring the accuracy of wind direction and wind speed data detection.

[0020] A spring 13 is installed between the adjusting wheel 12 and the mounting plate 11 to filter and reduce the vibration generated by the wind turbine during power generation, thereby reducing the impact of vibration on the anemometer 15 and wind vane 16, increasing the service life of the instruments, and ensuring the accuracy of the test results.

[0021] The central axis of column 14 coincides with the central axis of the tower 1 and the nacelle 2. By aligning the central axis of column 14 with the central axis of the tower 1 and the nacelle 2, it is possible to ensure that during the rotation of the nacelle 2 on the tower 1 by the drive motor 6, the mounting platform 9, mounting plate 11, column 14, etc., rotate together with the nacelle 2, but the central axis of column 14 remains aligned with the central axis of the tower 1 and the nacelle 2. This prevents the rotation of the nacelle 2 from affecting the horizontal performance of the anemometer 15 and wind vane 16 mounted on column 14, and prevents the movement of the nacelle 2 from disrupting the stable operation of the anemometer 15 and wind vane 16.

[0022] Multiple levels 19 are equidistantly arranged around the circumference of the mounting plate 11. By adjusting the height of the mounting plate 11 by adjusting the adjusting wheel 12, it is easy to observe the horizontal state of the mounting plate 11. Adjusting the column 14 to be in the vertical direction ensures that the anemometer 15 and wind vane 16 operate in the horizontal direction. The operation process is simple and convenient.

[0023] like Figure 6As shown, a rotating wheel 20 is provided at the bottom of the rotating shaft 17; three different colored display areas 21 are provided on the outer side of the rotating wheel 20; a color sensor 22 is provided on the controller 18 facing the rotating wheel 20. The controller detects wind speed and wind direction data through the anemometer 15 and the wind vane 16, and then processes the information through the controller 18 to control the drive motor 6 to drive the nacelle 2 to rotate and adjust the wind turbine 3 to align with the wind direction. At the same time, the rotation of the wind vane 16 will drive the rotating shaft 17 to rotate the rotating wheel 20. The color display area 21 relative to the color sensor 22 is changed. The changed color display area 21 further reminds the controller 18 to drive the nacelle 2 to rotate and adjust the wind turbine 3 to align with the wind direction through the drive motor 6. The two prompting methods operate synchronously, increasing the stability of the wind turbine yaw detection device.
