Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade maintenance technology, specifically to a flipping mechanism for transferring the trailing edge serrations of wind turbine blades. Background Technology

[0002] With the development of the wind power industry, the installed capacity of wind turbines in my country is increasing day by day. As the equipment for capturing wind energy, the wind turbine blade is the core component of the wind turbine unit. To reduce the operating noise of wind turbine blades and extend their lifespan, installing trailing edge serrations is one of the most widely used solutions. Essentially, this reduces the aerodynamic noise generated by the interaction between turbulence on the blade surface and the trailing edge airfoil. Therefore, adding trailing edge serrations can effectively reduce blade vibration, prevent blade fatigue damage, and reduce maintenance costs.

[0003] During transportation, the trailing edge saw teeth, which are placed horizontally on the main frame, need to be flipped into an upright position and raised to a certain height so that they can be easily transported to the position on the wind turbine blade that needs to be pasted by two sets of conveyor rollers. However, most existing technologies still rely on manual handling, which increases the workload of workers and also makes the transfer efficiency low. Utility Model Content

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] like Figures 1 to 5 As shown, this utility model provides a flipping mechanism for transferring the sawtooth edge of a wind turbine blade, including: a bevel gear set, a suction cup 55, and a movable plate set;

[0037] The upper and lower plates 523 in the movable plate group are slidably mounted on the main frame via vertical slide rails, and the left and right plates 524 are slidably mounted on the upper and lower plates 523 via horizontal slide rails. Thus, when the upper and lower plates 523 move vertically in a periodic motion, they can drive the left and right plates 524 to move vertically in a periodic motion synchronously.

[0038] The fixed bevel gear 541 in the bevel gear set is fixed on the left and right plates 524, and the movable bevel gear 542 connected to the suction cup 55 is installed on the horizontal connecting rod 525.

[0039] The movable bevel gear 542 and the suction cup bracket 551 of the suction cup 55 are both fixed on the transverse shaft 571, and the transverse shaft 57 is mounted on the L-shaped frame 575 through bearings;

[0040] The fixed bevel gear 541 is fixed to the support platform 573 on the side of the left and right plates 524 by the vertical support rod 572;

[0041] The vertical support rod 572 is also fitted with a sleeve 574, which can rotate axially relative to the vertical support rod 572. One end of the horizontal connecting rod 525 and the L-shaped frame 575 are detachably connected to the sleeve 574. In the detached state, the relative position of the horizontal connecting rod 525 and the L-shaped frame 575 can be adjusted. In the tightened state, the horizontal connecting rod 525 and the L-shaped frame 575 can rotate synchronously. The other end of the horizontal connecting rod 525 is rotatably connected to the upper and lower plates 523.

[0042] When driven, the upper and lower plates 523 can perform vertical periodic movements, thereby driving the suction cup 55 to perform vertical periodic movements, causing the suction cup 55 with the serrated tail edge to move upward. When driven, the left and right plates 524 can perform horizontal periodic movements, thereby pushing or pulling the horizontal connecting rod 525 through the left and right plates 524, causing the suction cup 55, the horizontal connecting rod 525, and the L-shaped frame 575 to rotate relative to the vertical support rod 572, i.e., the fixed bevel gear 541, which in turn drives the axial rotation of the movable bevel gear 542. Since the movable bevel gear 542 is meshed with the fixed bevel gear 541, under the action of the fixed bevel gear 541, the movable bevel gear 542 rotates axially, thereby driving the suction cup 55 with the serrated tail edge to rotate. That is, the movable bevel gear 542 rotates around the support rod 572 and is driven by the meshed fixed bevel gear 541 to rotate along its own axis, so that the serrated tail edge completes the combined action of lifting and flipping.

[0043] Specifically, the tilting mechanism also includes a cam assembly and a linkage assembly;

[0044] The cam assembly includes cam I 511 and cam II 512, and the linkage assembly includes upper and lower linkages 521 and left and right linkages 522;

[0045] Rollers are provided on the first and last sides of the upper and lower connecting rods 521 and on the first and last sides of the left and right connecting rods 522.

[0046] The bottom of the upper and lower plates 523 is provided with horizontal grooves 5231, and the left and right plates 524 are provided with vertical grooves 5241;

[0047] The tail roller of the upper and lower connecting rod 521 is slidably mounted on the transverse groove 5231. One end of the tension spring I is hooked on the plate frame 56, and the other end is hooked on the upper and lower connecting rod 521, so that the first roller of the upper and lower connecting rod 521 elastically abuts against the cam I 511.

[0048] The first end of the left and right connecting rods 522 is rotatably connected to the plate frame 56, and the tail roller of the left and right connecting rods 522 is slidably mounted on the vertical groove 5241. One end of the tension spring II is hooked on the plate frame 56, and the other end is hooked on the left and right connecting rods 522, so that the first roller of the left and right connecting rods 522 elastically abuts against the cam II 512.

[0049] The design of tension springs I and II ensures that the rollers never leave the contour range of cams I and II. The upper and lower connecting rods 521 and the left and right connecting rods 522 oscillate periodically under the drive of cams I 511 and cam II 512, thereby driving the upper and lower plates 523 and the left and right plates 524 to perform vertical and horizontal periodic movements.

[0050] Specifically, both cam I 511 and cam II 512 are fixed on the drive shaft 561, which is mounted on the plate frame 56 via bearings. The flipping mechanism also includes a drive motor 53, which is fixed on the plate frame 56. Its output end passes through the plate frame 56 and is connected to a drive gear. A drive gear 562 that meshes with the drive gear is also fixed on the drive shaft 561.

[0051] like Figures 6 to 7 As shown, taking the upward movement of the upper and lower plates 523 and the left and right plates 524 as the positive direction, the rhythm of the movement of the upper and lower plates 523 and the left and right plates 524 is as follows: Figure 7 The motion trajectory of the suction cup 55 is the superposition trajectory of the movement of the upper and lower plates 523, the left and right plates 524 and the rotation of the movable bevel gear 542, and the rotation angle of the movable bevel gear 542 is 90 degrees.

[0052] The working principle and process of this utility model are as follows:

[0053] After the suction cup 55 adsorbs the serrated edge, the drive motor 53 drives the cam I 511 and cam II 512 to rotate, causing the upper and lower plates 523 to oscillate periodically under the influence of the upper and lower connecting rods 521. Driven by the upper and lower connecting rods 521, the upper and lower plates 523 can perform vertical periodic motion, thereby driving the suction cup 55 to move vertically periodically, causing the suction cup 55 with the serrated edge to move upwards. The left and right plates 524, driven by the left and right connecting rods 522, can perform horizontal periodic motion, thereby pushing and pulling the horizontal connecting rod 525, causing the suction cup 55, the horizontal connecting rod 525, and the L... The frame 575 rotates relative to the vertical support rod 572, i.e., the fixed bevel gear 541, which in turn drives the axial rotation of the movable bevel gear 542. Since the movable bevel gear 542 is engaged with the fixed bevel gear 541, the movable bevel gear 542 rotates axially under the action of the fixed bevel gear 541, which in turn drives the suction cup 55 with the tail edge sawtooth to rotate. That is, the movable bevel gear 542 rotates around the support rod 572 and is driven by the engaged fixed bevel gear 541 to rotate along its own axis, so that the tail edge sawtooth completes the combined action of lifting and flipping.

[0054] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
