Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade maintenance technology, specifically to a mechanism for removing excess adhesive from 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] The connection between the trailing edge serrations and the wind turbine blades is mostly achieved by adhesive bonding. This involves applying adhesive to the trailing edge serrations and then attaching the adhesive-coated end face to the wind turbine blade. However, after the trailing edge serrations are attached to the wind turbine blade, excess adhesive may appear at the edges of the blade and the trailing edge serrations. In current technology, the excess adhesive is often removed by manually wiping it off, which is both labor-intensive and inefficient. Utility Model Content

[0004] In view of this, the problem to be solved by this utility model is to provide an overflow adhesive removal mechanism for the trailing edge serrations of wind turbine blades.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An overflow adhesive removal mechanism for the trailing edge serrations of wind turbine blades includes an inverted V-shaped roller assembly, a towel roller, and a conical rubber-coated roller.

[0007] The inverted V-shaped roller assembly is used to clamp the wind turbine blade in the thickness direction;

[0008] The conical rubber-coated roller is located on the side behind the inverted V-shaped roller group. When driven, it can move back and forth along the direction of the inverted V-shaped roller group to abut against the serrated edge after the rubber coating, so that the serrated edge is in close contact with the wind turbine blade.

[0009] The towel roller is located on the front side of the inverted V-shaped roller assembly and is used to abut against the wind turbine blade with serrated trailing edges.

[0010] In addition to the glue overflow mechanism, the main frame is also included. The main frame includes an n-shaped frame part and a strip-shaped frame part constructed at the bottom of the two legs of the n-shaped frame part; the inverted V-shaped roller assembly is mounted on the n-shaped frame part.

[0011] The tapered rubber-coated roller is vertically mounted on the tapered rubber-coated roller bracket. The vertical support rod I on the rubber-coated roller bracket is rotatably connected to the strip frame part through the rotating arm I; the vertical support rod II on the rubber-coated roller bracket is rotatably connected to the strip frame part through the rotating arm II.

[0012] In addition to the glue overflow mechanism, there is also a cylinder, which is horizontally mounted on the strip frame. The output end of the cylinder is rotatably connected to the vertical support rod II through a constant force pneumatic strut.

[0013] The main frame is also equipped with a suction cup robotic arm for picking up and placing the tail edge serrations.

[0014] The left and right sides of the main frame are also equipped with track assemblies for moving the main frame.

[0015] The advantages and positive effects of this utility model are:

[0016] (1) A towel roller is provided. When the glue removal mechanism moves relative to the wind turbine blade, the towel roller rotates relative to the wind turbine blade under the action of friction. The towel strip on the towel roller contacts and rubs with the surface of the attached tail edge serration, thereby removing the glue overflow at the tail edge serration and the edge of the wind turbine blade. Compared with the manual wiping method, this reduces the workload of workers and improves the efficiency of glue removal.

[0017] (2) A conical rubber-coated roller is provided, which abuts against the serrated edge after being driven. Before the glue is initially cured, the serrated edge is tightly attached to the wind turbine blade, preventing the serrated edge from slipping off the wind turbine blade under its own weight, thus improving the bonding strength between the serrated edge and the wind turbine blade.

[0025] 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.

[0026] like Figures 1 to 2 As shown, this utility model provides a glue removal mechanism for the trailing edge serrations of wind turbine blades, including an inverted V-shaped roller group 15, a towel roller 64, and a conical rubber-coated roller 63;

[0027] The inverted V-shaped roller assembly 15 is used to clamp the wind turbine blade in the thickness direction. That is, the rollers on the left and right sides of the V-shaped roller assembly 15 provide support for the wind turbine blade on the left and right sides, so that the glue removal mechanism is installed vertically on the wind turbine blade.

[0028] The conical rubber-coated roller 63 is located on the side behind the inverted V-shaped roller group 15. When driven, it can move back and forth along the direction of the inverted V-shaped roller group 15 to abut against the tail edge saw teeth after the glue is applied. Before the glue is initially cured, the tail edge saw teeth are tightly attached to the wind turbine blade, preventing the tail edge saw teeth from slipping off the wind turbine blade under its own weight.

[0029] The towel roller 64 is located on the front side of the inverted V-shaped roller assembly 15 and is used to abut against the wind turbine blade with the trailing edge serrations. After the glue has initially cured, the entire glue removal mechanism moves forward. Under the action of friction, the towel roller 64 rotates relative to the wind turbine blade. The towel strips on the towel roller 64 contact and rub against the surface of the trailing edge serrations that have been glued, thereby removing the excess glue.

[0030] Specifically, in addition to the glue overflow mechanism, the main frame 2 is also included. The main frame 2 includes an n-shaped frame part 23 and a strip-shaped frame part 24 constructed at the bottom of the two legs of the n-shaped frame part 23; the inverted V-shaped roller assembly 15 is mounted on the n-shaped frame part 23.

[0031] A tapered rubber-coated roller 63 is vertically mounted on a tapered rubber-coated roller bracket 631. The vertical support rod I 6311 on the rubber-coated roller bracket 631 is rotatably connected to the strip frame part 24 via a rotating arm I 651. The vertical support rod II 6312 on the rubber-coated roller bracket 631 is rotatably connected to the strip frame part 24 via a rotating arm II 652. In addition to the glue overflow mechanism, a cylinder 61 is also included. The cylinder 61 is horizontally mounted on the strip frame part 24. The output end of the cylinder 61 is rotatably connected to the vertical support rod II 6312 via a constant force pneumatic strut 621.

[0032] When the cylinder 61 extends, it pushes the rubber-coated roller bracket 631 through the constant force pneumatic strut 621. The rubber-coated roller bracket 631 is acted upon by the rotating arm I 651 and the rotating arm II 652, and moves in the direction close to the V-shaped roller group 15, thereby causing the conical rubber-coated roller 63 to apply constant pressure to the tail edge serrations until the glue is initially cured.

[0033] When the cylinder 61 retracts, the constant force pneumatic strut 621 pulls the rubber-coated roller bracket 631. The rubber-coated roller bracket 631 is moved away from the V-shaped roller group 15 by the action of the rotating arm I 651 and the rotating arm II 652, thereby causing the conical rubber-coated roller 63 to separate from the tail edge serration.

[0034] like Figure 1 and Figure 3As shown, specifically, the left and right sides of the main frame 2 are also equipped with track assemblies 12 for moving the main frame 2. The combination of the two sets of track assemblies 12 is also an inverted V-shaped structure, which provides support force to the wind turbine blades on the left and right sides. In conjunction with the inverted V-shaped roller assembly 15, the overflow removal mechanism is vertically installed on the wind turbine blade. When the track of the track assembly 12 starts, the entire overflow removal mechanism is driven forward under the action of friction.

[0035] Specifically, the main frame 2 is also equipped with a suction cup robot 5 for picking up and placing the trailing edge saw teeth. The suction cup robot 5 is a multi-degree-of-freedom flipping robot. The trailing edge saw teeth can be placed flat on the main frame 2. When the glue removal mechanism moves to the position where the trailing edge saw teeth need to be pasted, the suction cup robot 5 picks up the trailing edge saw teeth and then lifts and flips them, so that the glue surface of the trailing edge saw teeth is pasted on the wind turbine blade.

[0036] The working principle and process of this utility model are as follows:

[0037] When it is necessary to attach the trailing edge saw teeth to the wind turbine blade, the track assembly 12 starts and drives the overflow adhesive removal mechanism to move upright on the wind turbine blade. When the overflow adhesive removal mechanism moves to the position where the trailing edge saw teeth need to be attached, the suction cup robot arm 5 picks up the trailing edge saw teeth on the main frame 2 and then lifts and flips them, so that the adhesive surface of the trailing edge saw teeth is attached to the wind turbine blade.

[0038] Then, cylinder 61 extends and pushes rubber-coated roller bracket 631 through constant force pneumatic strut 621. Rubber-coated roller bracket 631 is moved in the direction close to V-shaped roller group 15 by the action of rotating arm I 651 and rotating arm II 652, thereby causing the conical rubber-coated roller 63 to apply constant pressure to the tail edge serration. After the glue has initially cured, cylinder 61 retracts and pulls rubber-coated roller bracket 631 through constant force pneumatic strut 621. Rubber-coated roller bracket 631 is moved in the direction away from V-shaped roller group 15 by the action of rotating arm I 651 and rotating arm II 652, thereby causing the conical rubber-coated roller 63 to separate from the tail edge serration. Track assembly 12 starts again, and the entire glue removal mechanism moves forward. Under the action of friction, towel roller 64 rotates relative to the wind turbine blade. The towel strip on towel roller 64 contacts and rubs against the surface of the glued tail edge serration, thereby removing the glue overflow.

[0039] 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.
