Technical Field
[0001] This utility model relates to the field of wind turbine technology, specifically a wind turbine transmission chain reset device. Background Technology
[0002] In recent years, with the continuous growth of global electricity demand and the sustained increase in carbon emissions, renewable energy power generation, especially wind power generation, has become the key to ensuring that future energy supply meets demand. As a pollution-free, high-yield, and renewable new energy source, wind energy has received widespread attention from countries around the world.
[0003] In existing technology, the speed measuring disc is a key component of wind turbine units, used to measure the rotational speed of the wind turbine. It is crucial for the stable operation and energy output of the unit. During the long-term use of wind turbine units, loosening or wear of the transmission chain can cause the speed measuring disc to become unstable and thus deviate. Therefore, it is necessary to regularly monitor and maintain the speed measuring disc of the wind turbine unit to detect and deal with potential deviation problems in a timely manner.
[0004] When resetting the speed measuring disc, it is necessary to push the speed measuring disc to the initial position and keep it stable so that it can be reset and repaired later. Usually, this is done by the operator manually pressing and holding the disc, which greatly increases the workload of the operator. To solve this problem, this utility model proposes a wind turbine drive chain reset device. Utility Model Content

[0016] This utility model proposes a wind turbine drive chain reset device, which can avoid manual pressing by the operator and continuously maintain the stability of the speed measuring disc, reducing the operator's workload. Specifically, it features 16 bolts evenly distributed on the surface of the rear pressure plate, combined with...

Furthermore, all embodiments can be used in combination with each other.
[0028] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a wind turbine transmission chain reset device, comprising: a wind turbine locking disc 1, a main shaft 5 is provided on the wind turbine locking disc 1, a speed measuring disc 4 and a back plate 6 are provided on the main shaft 5, a rear pressure plate 2 is provided on the surface of the back plate 6 facing the speed measuring disc 4, a bolt 3 is screwed on the rear pressure plate 2, a side lug 10 is fixed on the surface of the abutment disc 7, a limit component 8 is provided on the side lug 10, a guide hole 20 is opened on the surface of the side lug 10, and a guide rod 9 is provided in the guide hole 20;
[0029] In use, a guide hole 20 is opened on the side ear 10 to facilitate matching with the guide rod 9, so as to realize the smooth movement of the clamping plate 7. Through the set limit component 8, after the speed measuring plate 4 is reset, the limit rod 17 can be inserted into the limit hole 19 to limit the clamping plate 7, thereby maintaining the stability of the speed measuring plate 4.
[0030] Example 2: Based on Example 1, there are several bolts 3, which are evenly distributed on the surface of the rear pressure plate 2. The back plate 6 is located between the wind turbine locking plate 1 and the speed measuring plate 4. The abutting plate 7 is in contact with and abuts the surface of the speed measuring plate 4. The abutting plate 7 is located on the periphery of the main shaft 5. The outer wall of the guide rod 9 and the inner wall of the guide hole 20 are slidably connected. One end of the guide rod 9 is rounded. The other end of the guide rod 9 is provided with a threaded end 21, and the threaded end 21 is provided with an external thread.
[0031] When using, combine Figure 2 and Figure 3As shown, there are 16 bolts 3. When the speed measuring disc 4 needs to be reset, remove the two bolts 3 located at about 12 o'clock on the rear pressure plate 2 and the two bolts 3 located at about 6 o'clock on the rear pressure plate 2, and tighten the threaded ends 21 of the four sets of guide rods 9 into them to fix the guide rods 9. The guide rods 9 slide continuously in the guide hole 20, providing stable guidance and support for the movement of the pressure disc 7, ensuring the stability of the speed measuring disc 4 during the reset process, and facilitating adjustment and control by the operator.
[0032] Example 3: Based on Example 2, the limiting rod 17 and the upright plate 18 are plugged together. A top plate 16 is fixed at the top of the limiting rod 17. The top plate 16 is disc-shaped. A spring 22 is sleeved on the limiting rod 17. The spring 22 is located between the top plate 16 and the upright plate 18. One end of the spring 22 is fixedly connected to the upright plate 18, and the other end of the spring 22 is fixedly connected to the top plate 16. A rotating column 14 is rotatably connected to the surface of the top plate 16. A pull ring 13 is fixed at the top of the rotating column 14. A locking rod 15 is fixed to the surface of the rotating column 14. The locking rod 15 can be embedded in the locking groove 12. In use, in the initial state of the limiting assembly 8, the end of the limiting rod 17 is located inside the upright plate 18, and the spring 22 is stretched and stores elastic potential energy. The locking rod 15 is set towards the outer extension rod 11 and is embedded in the locking groove 12. This ensures that the pressing plate 7 can be pushed stably, avoiding contact between the limiting rod 17 and the guide rod 9 and causing obstruction.
[0033] A limiting hole 19 is provided on the surface of the guide rod 9. The limiting hole 19 is provided according to the reset position of the speed measuring disk 4. The limiting rod 17 is inserted into the limiting hole 19. When in use, when the limiting rod 17 is inserted into the limiting hole 19, the limiting component 8 is fixed because the guide rod 9 is fixed, which in turn fixes the side ear 10, and then fixes the clamping disk 7, thereby achieving effective limiting of the speed measuring disk 4.
[0034] Working principle: In actual use, 16 bolts are set (3), and they are evenly distributed on the surface of the rear pressure plate (2). Figure 2 and Figure 3As shown, when the speed measuring disc 4 needs to be reset, remove the two bolts 3 located at approximately 12 o'clock on the rear pressure plate 2 and the two bolts 3 located at approximately 6 o'clock on the rear pressure plate 2, and tighten the threaded ends 21 of the four sets of guide rods 9 into them to fix the guide rods 9. Then move the clamping plate 7 to the main shaft 5, insert the guide rods 9 into the corresponding guide holes 20 and push them continuously, so that the clamping plate 7 continuously approaches the speed measuring disc 4 until it contacts it, and continue to push it to reset the speed measuring disc 4. When the speed measuring disc 4 is reset, the limiting hole 19 and the limiting rod 17 correspond. By pulling the pull ring 13, the locking rod 15 is removed from the locking groove 12. Then rotate the pull ring 13 to rotate the locking rod 15 away from the outer extension rod 11. Then release the pulling force on the pull ring 13. Under the rebound action of the spring 22, the limiting rod 17 will be inserted into the limiting hole 19, thereby limiting the clamping plate 7 and maintaining the stability of the speed measuring disc 4.
