Description

Technical Field

[0001] This utility model belongs to the field of wind turbine generator maintenance technology, and in particular relates to a repair device for the fuse breakage of the rotor lead wire of a wind turbine generator. Background Technology

[0002] With the continuous development of wind power generation technology, wind turbine generators are increasingly widely used in new energy systems. The wind turbine generator rotor is a key component inside the generator, responsible for converting wind energy into electrical energy. The lead wires, as conductors connecting the generator's internal windings to the external circuit, are prone to insulation damage or conductor breakage due to overload, short circuits, vibration, etc., leading to fuse failures during long-term operation. To ensure safety, it is necessary to promptly disconnect the lead wires for replacement or repair. In such cases, the lead wires must be reliably disconnected to avoid secondary faults and improve maintenance efficiency and operational safety.

[0003] However, currently, most cutting operations are performed manually using handheld wire cutters, wire strippers, and other tools. During the cutting process, the lead wire is prone to slipping, shifting, or shaking, resulting in inaccurate cutting positions and uneven cuts. These problems not only affect the quality of repairs but may also damage adjacent windings or insulation structures, increasing the difficulty of repairs and maintenance costs.

[0004] Therefore, it is necessary to design a repair device for the fuse failure of the rotor lead wire of a wind turbine generator to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing manual cutting methods, which easily lead to slippage and displacement of the lead wire, affecting cutting accuracy and increasing repair difficulty and maintenance costs, this utility model provides a repair device for the fuselage of the rotor lead wire of a wind turbine generator.

[0006] This utility model is achieved through the following technical means: a repair device for the fuse of a wind turbine generator rotor lead wire, comprising a guide block, a motor, a bidirectional lead screw, a slider, a cutting blade, a pressure plate, a guide rod, a compression spring, and an auxiliary clamping assembly. The motor is installed at one end of the guide block, with its output shaft extending to the left. The bidirectional lead screw is rotatably disposed inside the guide block, and the output shaft of the motor is fixedly connected to one end of the bidirectional lead screw. Two sliders are symmetrically distributed and slidably disposed inside the guide block. The bidirectional lead screw passes through the two sliders and is threadedly connected to them. A cutting blade is installed on the side of the two sliders that are close to each other, and the cutting tips of the two cutting blades are opposite each other. Multiple guide rods are slidably disposed on the side of the two sliders that are close to each other, distributed along a rectangular direction. A pressure plate is fixedly connected between one end of the multiple guide rods on the same side. An opening is reserved on the pressure plate to accommodate the cutting blade passing through. A compression spring is fixedly connected between each guide rod and the corresponding slider. The auxiliary clamping assembly is disposed between the guide block and the two sliders.

[0007] In one embodiment, the auxiliary pressing assembly includes a connecting block, a rotating block, a pressure roller, a rotating plate, a sliding plate, and a telescopic spring. Two connecting blocks are arranged side by side and fixed to the outside of the guide block. Two rotating blocks are rotatably arranged on each connecting block. A pressure roller is rotatably arranged on each rotating block. Two rotating plates are rotatably arranged at the lower part of each slider. A sliding plate is rotatably arranged at one end of each pressure roller. The sliding plate extends into the corresponding rotating plate and slides therewith. Two symmetrically distributed telescopic springs are fixed between the roller and the rotating plate.

[0008] In one embodiment, the motor is a servo motor.

[0009] In one embodiment, the slider and the guide block are connected by a slidable engagement of a protrusion and a groove structure.

[0010] In one embodiment, the pressing surface of the pressure plate is covered with a rubber pad.

[0011] In one embodiment, the surface of the pressure roller is wrapped with a ring of anti-slip pads.

[0012] Beneficial effects: Through the cooperative structure of the pressure plate, guide rod and compression spring, the pressure plate can apply pressure to the area around the cutting point of the lead wire before the cutting blade contacts the lead wire, stabilizing and fixing it, effectively preventing the lead wire from shaking or shifting during the cutting process. At the same time, the pressure rollers in the auxiliary clamping assembly further apply pressure to the lead wire from different directions, forming a synergistic clamping effect with the pressure plate, significantly enhancing the overall clamping effect, thereby ensuring that the cutting process is more accurate, stable and safe.

[0019] Example: A repair device for a blown rotor lead wire of a wind turbine generator, such as... Figures 1-5 As shown, the assembly includes a guide block 1, a motor 2, a bidirectional lead screw 3, sliders 4, a cutter 5, a pressure plate 7, a guide rod 8, a compression spring 9, and an auxiliary clamping assembly. The motor 2 is bolted to the right end of the guide block 1, with its output shaft extending to the left. The motor 2 is a servo motor, capable of precisely controlling speed and direction. The bidirectional lead screw 3 is rotatably mounted inside the guide block 1. The output shaft of the motor 2 is fixedly connected to the right end of the bidirectional lead screw 3 via a coupling. Two sliders 4 are symmetrically distributed and slidably mounted inside the guide block 1 via a protrusion and groove structure, ensuring the smooth sliding of the sliders 4. The bidirectional lead screw 3 passes through the two sliders 4 and is threaded to them. The sides of the two sliders 4 closest to each other are bolted together. There is a cutting blade 5, and the cutting tips of the two cutting blades 5 are opposite each other, which can cooperate to cut the lead wire. On the side of the two sliders 4 that are close to each other, there are four guide rods 8 distributed along a rectangular direction. A pressure plate 7 is fixedly connected to one end of the four guide rods 8 on the same side. The pressure plate 7 has a rectangular opening for the cutting blade 5 to pass through. The pressure surface of the pressure plate 7 is covered with a rubber pad. The rubber pad has a certain elasticity and friction, which can play an anti-slip role when pressing the lead wire. A compression spring 9 is fixedly connected between each guide rod 8 and the corresponding slider 4, which provides a reset force and a clamping force for the guide rod 8 and the pressure plate 7. An auxiliary clamping assembly is set between the guide block 1 and the two sliders 4.

[0020] like Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary clamping assembly includes a connecting block 10, a rotating block 11, a pressure roller 12, a rotating plate 13, a sliding plate 14, and a telescopic spring 15. Two connecting blocks 10 are arranged side by side and fixedly connected to the outside of the guide block 1. Two rotating blocks 11 are rotatably arranged on each connecting block 10. A pressure roller 12 is rotatably arranged on each rotating block 11. The surface of the pressure roller 12 is wrapped with a rubber anti-slip pad to further enhance the friction between the pressure roller 12 and the lead wire and ensure the clamping effect. Two rotating plates 13 are rotatably arranged at the lower part of each slider 4. A sliding plate 14 is rotatably arranged at the lower end of each pressure roller 12. The sliding plate 14 extends into the corresponding rotating plate 13 and slides therewith. Two symmetrically distributed telescopic springs 15 are fixedly connected between the sliding plate 14 and the rotating plate 13 to provide a reset force and clamping force for the sliding plate 14 and the pressure roller 12.

[0021] When using this equipment, the operator first places the equipment in a suitable position, so that the lead wire to be cut is placed between the two cutting blades 5. Then, the motor 2 is started, and its output shaft drives the bidirectional lead screw 3 to rotate clockwise. Under the drive of the bidirectional lead screw 3, the two sliders 4 move inward synchronously to approach the lead wire.

[0022] As the slider 4 moves, the pressure plate 7 first contacts the surface of the lead wire. Since the pressure plate 7 and the slider 4 are connected by the guide rod 8 and the compression spring 9, as the slider 4 continues to move inward, the pressure plate 7 moves outward under the pressure of the lead wire, causing the guide rod 8 to slide into the slider 4 and squeeze the compression spring 9. At this time, the pressure plate 7 applies pressure to the area around the cut point of the lead wire to fix it.

[0023] At the same time, the pressure rollers 12 (i.e., four pressure rollers 12) also contact the surface of the lead wire. Under the pressure of the lead wire, the pressure rollers 12 drive the slide plate 14 to slide into the rotating plate 13 and squeeze the telescopic spring 15. At this time, the pressure rollers 12 apply pressure to the lead wire from different directions and work together with the pressure plate 7 to further press the area around the cutting point of the lead wire, ensuring that the lead wire will not shake or shift during the cutting process.

[0024] As slider 4 continues to move inward, the cutting blade 5 passes through the rectangular opening on the pressure plate 7 and cuts the lead wire. After the cutting is completed, the output shaft of the control motor 2 drives the bidirectional lead screw 3 to rotate counterclockwise, driving the two sliders 4 to move outward synchronously to reset. During the reset, the pressure plate 7 disengages from the lead wire, the compression spring 9 returns to its original state, and pushes the guide rod 8 to drive the pressure plate 7 back to the initial position. The pressure roller 12 also returns to the initial position under the action of the slide plate 14 and the telescopic spring 15, completing one lead wire cutting operation. Finally, the motor 2 is turned off, and the equipment returns to the standby state.
