[0002] The yaw gear is a key component in a wind turbine's yaw system. It's typically mounted at the base of the nacelle, with its upper end supporting the entire nacelle structure and its lower end bolted to the tower. The yaw gear ring meshes with the yaw reducer output gear. Driven by the yaw motor, it slowly rotates the entire nacelle structure to adjust the direction of the wind turbine rotor.

[0026] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

By setting the oil box 21, when the yaw gear is automatically oiled, the base 1 The oil tank 21 is connected to the oil filling hole on the outside of the yaw gear by connecting one end of the oil pipe 26 to the oil filling hole on the outside of the yaw gear. The lubricating oil is added to the inside of the oil box 21 through the through hole 28 inside the round rod 24, and the amount of lubricating oil inside the oil box 21 is observed through the transparent PC plate 27 on one side of the oil box 21. After the addition is completed, the plug rod 29 is inserted into the through hole 28 and the plug rod 29 is rotated so that the plug rod 29 is threadedly connected to the top of the inner wall of the through hole 28 to block the inside of the through hole 28. By adjusting the parameters of the control component inside the base 1, the electric push rod 22 is operated regularly to extend and drive the rectangular rod 23 to move, so that the round rod 24 pushes the push plate 25 to slide on the inner wall of the oil box 21, and the lubricating oil inside the oil box 21 is pressed into the oil pipe 26 and enters the inside of the yaw gear to lubricate the yaw gear, thereby avoiding the phenomenon of insufficient lubrication of the yaw gear as much as possible and reducing the number of manual oiling.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the top of the plug rod 29 is fixedly connected to an operating block 210, and the outer surface of the operating block 210 is fixedly connected to a plurality of protrusions. Holding the protrusions on the outer surface of the operating block 210 can more conveniently push the operating block 210 to control the rotation of the plug rod 29 without slipping. The bottom end of the operating block 210 is fixedly connected to a gasket 211, and the gasket 211 is a rubber sheet made of rubber material. When the plug rod 29 is completely inside the through hole 28, the gasket 211 will be at the top of the round rod 24 and fit tightly with the top of the round rod 24. The top of the inner wall of the through hole 28 can be further sealed by the rubber gasket 211 to prevent the oil inside the oil box 21 from leaking through the gap between the through hole 28 and the plug rod 29 as much as possible.

[0029] Specifically, such as Figure 2 and Figure 3As shown, an elastic rope 212 is fixedly connected to one side of the rectangular rod 23, and the end of the elastic rope 212 away from the rectangular rod 23 is rotatably connected to the top of the plug rod 29. By setting the elastic rope 212, the plug rod 29 can always be fixed to one side of the rectangular rod 23, which makes it easy to take the plug rod 29 for use and avoids accidental loss of the plug rod 29 when taking it out.

[0030] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the oil delivery pipe 26 is provided with an anti-backflow mechanism 3, which includes a groove block 31. The outer surface of the groove block 31 is fixedly connected to the inner wall of the oil delivery pipe 26. A circular hole 32 and two L-shaped holes 34 are opened in the groove block 31. The two L-shaped holes 34 are respectively located on the left and right sides of the circular hole 32. A cylindrical rod 33 is slidably connected to the inner wall of the circular hole 32. One end of the groove block 31 is fixedly connected to a U-shaped block 35. One end of the cylindrical rod 33 is provided with a spring 36. The upper and lower ends of the spring 36 are respectively fixedly connected to one end of the cylindrical rod 33 and one side of the U-shaped block 35. When the oil filling mechanism 2 is in operation, the push plate 25 applies pressure to the inside of the oil box 21 to make When the lubricating oil enters the oil delivery pipe 26, it will push the cylindrical rod 33 to slide on the inner wall of the circular hole 32 toward the U-shaped block 35 and compress the spring 36. At this time, the lubricating oil can pass through the circular hole 32 into the two L-shaped holes 34 and then enter the other end of the oil delivery pipe 26 to fill the yaw gear with oil. When the oil filling mechanism 2 stops running, the spring 36 will return to its original shape and push the cylindrical rod 33 to slide away from the U-shaped block 35 to return to its original position, blocking one end of the two L-shaped holes 34 through the cylindrical rod 33, thereby preventing the oil output from the yaw gear and the oil delivery pipe 26 from flowing back into the oil box 21 through the oil delivery pipe 26 and affecting the oil filling effect of the oil filling mechanism 2.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, the bottom end of the cylindrical rod 33 is fixedly connected to two blocking rods 37, and the length of the blocking rod 37 is less than the distance between the end of the cylindrical rod 33 away from the spring 36 and the end of the two L-shaped holes 34 located inside the slot block 31. When the cylindrical rod 33 moves inside the circular hole 32 to open the two L-shaped holes 34, one end of the two blocking rods 37 will contact one side of the U-shaped block 35, limiting the movement range of the cylindrical rod 33, and avoiding as much as possible the cylindrical rod 33 from moving too far, causing the spring 36 to be compressed and seriously affecting subsequent use. A positioning rod 38 is fixedly connected to one side of the U-shaped block 35, and the positioning rod 38 is located inside the spring 36. When the spring 36 is deformed, it will move on the outside of the positioning rod 38. The internal shape of the spring 36 can be reinforced by the positioning rod 38, and the spring 36 can be avoided as much as possible from being twisted and affecting normal use.

[0032] The working principle of this utility model is:

[0033] S1. When installing the oil filling mechanism, install the base 1 on one side of the yaw gear, and use tools such as bolts to pass through the mounting hole 4 on the outer surface of the base 1 to fix the base 1 to the working environment of the yaw gear. Connect one end of the oil pipe 26 to the oil filling hole on the outside of the yaw gear, add lubricating oil to the inside of the oil box 21 through the through hole 28 inside the round rod 24, and observe the amount of lubricating oil inside the oil box 21 through the transparent PC plate 27 on one side of the oil box 21. After adding, insert the plug rod 29 into the through hole 28, rotate the plug rod 29 so that the plug rod 29 is threadedly connected to the top of the inner wall of the through hole 28 to block the inside of the through hole 28, and adjust the parameters of the control components inside the base 1.

[0034] S2. Make the electric push rod 22 operate regularly and extend to drive the rectangular rod 23 to move, so that the round rod 24 pushes the push plate 25 to slide on the inner wall of the oil box 21, and presses the lubricating oil inside the oil box 21 into the oil pipe 26. When the lubricating oil enters the oil pipe 26, it pushes the cylindrical rod 33 to slide on the inner wall of the circular hole 32 toward the direction of the U-shaped block 35 and compresses the spring 36. At this time, the lubricating oil can pass through the circular hole 32 into the two L-shaped holes 34 and enter the other end of the oil pipe 26 through the groove block 31 to oil the yaw gear. When the oil filling mechanism 2 stops running, the spring 36 will return to its original shape and push the cylindrical rod 33 to slide away from the U-shaped block 35 to return to its original position, blocking one end of the two L-shaped holes 34 through the cylindrical rod 33.
