Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind turbine rotor rotation baking device. Background Technology

[0002] The insulating varnish on the rotor of a wind turbine plays a crucial role. It prevents short circuits between wires inside the motor or between the wires and the motor casing. The insulating varnish typically has good thermal conductivity, helping to conduct heat generated inside the motor to the outside, thereby reducing the motor's operating temperature. Good insulation reduces energy loss and improves motor efficiency. Therefore, the quality of the insulating varnish directly affects the lifespan of the motor.

[0003] The current drying method involves placing the varnish-soaked rotor vertically on a flatcar into a drying oven. This method results in uneven heating of the motor rotor, causing the insulating varnish to flow from top to bottom during heating, leading to uneven varnish thickness and slow curing. This drying process requires two varnish soakings and two drying cycles, which is inefficient. Poor localized treatment can lead to variations in motor performance and a decline in product quality.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0017] refer to Figure 1 As shown in the figure, this application discloses a wind turbine rotor rotation baking device, including a drive component 1. The output end of the drive component 1 drives the rotation component 2 to rotate through the sprocket box 3. The rotation component 2 and the sprocket box 3 are mounted on the base 4. In this embodiment, the base 4 is provided with two sets of rotation components 2, which can make greater use of the space of the baking room and simultaneously rotate and bake two rotors to improve work efficiency.

[0018] The rotating assembly 2 includes a rotor shaft 22, on which a rotor 21 is fitted. One end of the rotor shaft 22 is connected to a sprocket box 3, and the other end is connected to a slip ring 24. Since the rotor is rotating continuously, the temperature measuring wire of the rotor 21 is led out from the iron core of the rotor 21 to the outside of the drying chamber through the slip ring 24 for real-time observation and control of the baking temperature. In this embodiment, only one rotor 21 is needed to reflect the temperature of the rotor 21 inside the drying chamber, so only one slip ring 24 is needed.

[0019] The rotating assembly 2 also includes a roller frame 23, with a roller 231 on the top of the roller frame 23. The roller frame 23 is tactilely connected to the rotor shaft 22 via the roller 231, and the bottom of the roller frame 23 is mounted on the base 4.

[0020] A circular hoop 221 is fixedly sleeved on the rotor shaft 22. The circular hoop 221 is located at both ends of the rotor 21. A boss is provided on the outer circumference of the circular hoop 221, and a groove is provided on the outer circumference of the roller 231. The boss of the circular hoop 221 and the groove of the roller 231 are connected to each other, so that the circular hoop 221 is rolled on the roller 231, thereby allowing the rotor shaft 22 to roll on the roller 231 and ensuring that the rotor shaft 22 is fixed in the axial direction.

[0021] The base 4 is provided with multiple T-slots 41. The base 4 is connected to the roller frame 23 through the T-slots 41. The roller frame 23 can move within the T-slots 41 to accommodate rotors 21 of different lengths.

[0022] The slip ring 24 is provided with a slip ring seat 241, and a slip ring bracket 242 is provided at the end of the slip ring seat 241 away from the slip ring 24. The end of the slip ring bracket 242 away from the slip ring seat 241 is connected to the side of the roller frame 23.

[0023] The drive assembly 1 includes a drive component 11, which is an explosion-proof motor. The output end of the drive component 11 is connected to a reducer 12. The end of the reducer 12 away from the drive component 11 is provided with a connector 13. The end of the connector 13 away from the reducer 12 is connected to a drive shaft 15 through a dial 14. The end of the drive shaft 15 away from the dial 14 is connected to a sprocket box 3. The function of the reducer 12 is to reduce the speed of the motor 11 and increase the output torque. The function of the dial 14 is to transmit the torque output by the reducer 12 to the dial 14 through the connector 13, and then to the sprocket box 3 through the dial 14.

[0024] The reducer 12 is mounted on the drive assembly bracket 16, which fixes the position of the entire drive assembly 1.

[0025] The sprocket box 3 is equipped with a sprocket. One end of the sprocket is connected to the drive shaft 15, and the other end is connected to the rotor shaft 22, so that the drive component 11 of the drive assembly 1 drives the two rotor shafts 22 to rotate simultaneously.

[0026] The specific working principle is as follows: The explosion-proof drive component 11 drives the reducer 12 and the sprocket in the sprocket box 3 to rotate together. The other end of the sprocket drives the rotor shaft 22 to rotate, thereby causing the rotor 21, which is mounted on the rotor shaft 22, to rotate. The rotor shaft 22 is supported by the roller frame 12, so that the rotor shaft 22 rotates on the roller frame 12, thereby realizing the principle of rotary baking.

[0027] The beneficial effects are: This invention maintains a uniform, slow rotation during the drying process of the insulating varnish, ensuring even heating, accelerating curing, and guaranteeing consistent curing across the entire rotor, resulting in a uniform varnish film thickness. This improves the quality stability of the motor product and reduces performance variations caused by poor local processing. It boasts low manufacturing cost, wide applicability, convenient maintenance, high processing efficiency, small footprint, and high safety and reliability.
