However, due to the special geographical and climatic conditions of plateau wind farms, such as low oxygen, high cold and strong gusts, the operation and maintenance of wind power equipment have been posed with unique challenges. Under these conditions, the maintenance of wind turbines is particularly critical, and the operation of the brake disc is an indispensable daily task.

[0024] Preferably, the heat dissipation module also includes a temperature sensor for monitoring the temperature of the brake disc in real time and adjusting the rotation speed of the cooling fan or the heat dissipation efficiency of the heat sink according to the temperature conditions.

[0025] The working principle and beneficial effects of the above technical solution are: The present invention provides a wind turbine brake disc turning system under a plateau wind farm environment, including a brake disc assembly having a brake disc body, wherein the brake disc body is provided with a heat dissipation groove, which is used to improve the heat dissipation performance of the brake disc, effectively reduce the temperature of the brake disc, and improve the braking performance; an actuator comprises a driving motor and a turning operation device, wherein the driving motor is connected to the brake disc assembly through the turning operation device, and is used to receive the turning control signal and drive the brake disc to perform a turning operation, which can effectively improve the working efficiency of the turning operation and reduce the efficiency of the staff; secondly, a reducer arranged on the actuator is used to adjust the output torque of the driving motor to meet the needs of different turning operations; a turning control module is used to monitor the operating parameters of the driving motor and the operating state of the brake disc assembly, and control the starting, Stop, forward and reverse rotation and speed adjustment. Secondly, through the set parameter acquisition unit, control signal generating unit and control signal sending unit, the influence of the cranking operation on the fan performance is effectively reduced, and the operation efficiency and stability of the fan are improved; a position detection module is used to detect the rotation position of the brake disc or the drive motor, and feed back the detected position information to the cranking control module to achieve precise control of the cranking operation, wherein the set position detector is an encoder or a Hall sensor, which can accurately detect the rotation angle and position of the brake disc or the drive motor; a heat dissipation module includes components such as a fan and a heat sink, and is connected to the brake disc assembly, and is used to further reduce the temperature of the brake disc during and after the cranking operation. At the same time, the heat dissipation grooves are distributed in a spiral or radial shape on the brake disc body to improve the heat dissipation efficiency.

[0026] When the above-mentioned cranking system is performing a cranking operation, it first obtains the operating parameters of the fan through the parameter acquisition module; then, according to the obtained operating parameters and the preset cranking operation requirements, a cranking control signal is generated through the control signal generation module; the cranking control signal is sent to the actuator to drive the brake disc to perform a cranking operation; secondly, the rotation position of the brake disc or the motor is monitored in real time through the position detector, and the cranking operation is adjusted according to the position information; at the same time, during and after the cranking operation, the temperature of the brake disc is reduced through the heat dissipation module.

[0027] Among them, the winch system has the following advantages: First, it improves the winch efficiency. By replacing manual operation with electronic control drive, the single winch operation time is shortened from several hours to several minutes. Especially in the daily maintenance of multiple wind turbines, the efficiency improvement is particularly significant. In the traditional method, the staff needs to manually rotate the small end of the gear disc. Due to the speed ratio, it takes a very long time to complete a circle of gear disc rotation. The automated design directly drives the large gear disc through mechanical power, avoiding unnecessary waste of time. Second, it enhances safety. In the plateau wind farm environment, safety is always the top priority of maintenance work. The traditional manual winch operation requires staff to work at close range. Contact with equipment can easily lead to safety accidents in strong gusts, and the above-mentioned turning system, through remote control and mechanized design, greatly reduces the frequency of direct contact between operators and equipment, significantly improving safety; thirdly, it improves economic benefits. The operation and maintenance costs of plateau wind farms are relatively high, of which labor costs and maintenance time account for a large proportion. The above-mentioned turning system indirectly increases the operating time of wind turbines by reducing the number of manual operations and shortening maintenance time, thereby increasing the power generation income of the wind farm. Assuming that the time of a single turning operation is saved by 50%, the economic benefit of reducing the cumulative maintenance time throughout the year will be considerable.

[0031] The working principle and beneficial effects of the above technical solution are: The above-mentioned turning operation device 1 is set up. When the wind turbine brake disc turning system is performing turning operation in a plateau wind farm environment, the operator first needs to check the appearance of the equipment to ensure that the electrical control box 8, the transmission mechanism 9 and the jacking drive mechanism 13 are well connected. Then, after connecting the 220V power supply, open the valve 32 and connect the air source to complete the pressurization preparation work of the transmission mechanism 9 and the jacking drive mechanism 13. After the entire turning system is ready, the driving rubber wheel of the jacking drive mechanism 13 is in close contact with the brake disc 14, and the brake caliper is released to release the gear disc.

[0032] Secondly, when the transmission mechanism 9 needs to be equipped with the jacking drive mechanism 13 to perform the turning operation, the valve 32 is first opened to connect the first gas pipeline 31 to the gas source, and at the same time the electric control box 8 controls the first solenoid valve 29 to close and the second solenoid valve 30 to open, and then the second gas pipeline 33 delivers the gas to the gas inlet specified by the piston cylinder 26, thereby pushing the piston rod 27 to slide left along the piston cylinder 26, and then the piston rod 27 pulls the hinged L-shaped rod 16 to rotate along the first hinge seat under the action of the second mounting seat 25, so that the L-shaped rod 16 rotates a certain angle and drives the hinged limit rod 24 to move left, and then the limit block 23 fixedly mounted on the second mounting plate 22 cooperates with the limit block 23, so that the L-shaped rod 16 is locked, and at this time the spring 17 is stretched, and then the L-shaped rod 16 drives the hinged transmission rod 18 to move downward, and then the transmission gears 21 at both ends of the transmission shaft 20 are realized with the driving gear 6 and the driven gear 12 The gear 21 is engaged with the driven gear 12, and the driven gear 12 is engaged with the driven gear 12, so that the rotating shaft 11 is rotated, and then the lifting drive mechanism 13 is driven to rotate to complete the turning operation; when the turning operation is completed, the electric control box 8 first controls the second solenoid valve 30 to close and the first solenoid valve 29 to open, and then the second gas pipeline 33 delivers gas to the gas inlet specified by the piston cylinder 26, thereby pushing the piston rod 27 to slide rightward along the piston cylinder 26, and then the piston rod 27 pulls the hinged L-shaped rod 16 under the action of the second mounting seat 25, so that the L-shaped rod 16 rotates a certain angle and drives the transmission rod 18 to move upward, and the elastic force of the spring 17 realizes the reset of the L-shaped rod 16, and then the transmission gear 21 is disengaged from the driving gear 6 and the driven gear 12, and at this time the transmission mechanism 9 is disconnected from the lifting drive mechanism 13, and the turning operation is completed. Through the transmission mechanism 9 and the control components of the turning operation device 1, the turning operation is performed with the design of an automatic mechanical device, which greatly improves the turning efficiency, reduces the manpower requirements, and enhances the safety; at the same time, it effectively improves the electronic control technology and the mechanical transmission device, and realizes efficient and stable operation of the sprocket.

[0033] Example 3 On the basis of Example 1 or 2, Figure 2 , Figure 4 As shown, the lifting drive mechanism 13 includes: a U-shaped bracket 34, the U-shaped bracket 34 is fixedly connected to one end of the rotating shaft 11, the top and bottom of the U-shaped bracket 34 are respectively embedded with grooves 35, and lifting cylinders 36 are fixedly installed in the two grooves 35, and the telescopic ends of the lifting cylinders 36 are respectively connected to driving components 37; The driving assembly 37 includes an auxiliary box 38, which is fixedly mounted on the side wall of the U-shaped bracket 34. One end of the first wedge block 39 slides through the side wall of the auxiliary box 38 and is fixedly connected to the telescopic end of the lifting cylinder 36. The lower end of the second wedge block 40 slides through the bottom of the auxiliary box 38 and is fixedly mounted with a rubber driving wheel 43. A spring 41 is sleeved on the second wedge block 40. A sliding rod 42 is fixedly connected to the side wall of the second wedge block 40, and one end of the sliding rod 42 is slidably connected to the side wall of the auxiliary box 38. The rubber driving wheel 43 is in contact with the brake disc 14, and the brake disc 14 is mounted on the connecting shaft 44.

[0034] The working principle and beneficial effects of the above technical solution are: The drive motor 4, transmission mechanism 9 and control components of the winch operation device 1 of the jacking drive mechanism 13 are provided above, so as to realize the winch operation of the fan and ensure the portability and versatility of the winch system. When the jacking drive mechanism performs the winch operation, the jacking cylinder 36 located in the groove 35 is first turned on and started. At this time, the electric control box 8 controls the action of the jacking cylinder 36, and then the jacking cylinder 36 drives the first wedge block 39 to slide to the left, so that the second wedge block 40 slides downward along the bottom of the auxiliary box 38.

At the same time, the spring 2 41 is compressed. At this time, the second wedge block 40 drives the rubber drive wheel 43 to tightly contact the brake disc 14. The U-shaped bracket 34 is tightly fitted, and then the U-shaped bracket 34 is rotated under the drive of the rotating shaft 11, so that the U-shaped bracket 34 cooperates with the driving component 37 to drive the brake disc 14, and then the disc turning operation is realized under the forward and reverse rotation of the driving motor 4; at the same time, after the disc turning operation is completed, the jacking drive mechanism 13 needs to be under the action of the jacking cylinder 36, and the elastic force of the second spring 41, so that the second wedge block 40 is reset, and then the rubber driving wheel 43 is separated from the brake disc 14, the driving motor 4 is turned off, the power is disconnected and the air pressure is released, and then the disc turning system is in a shutdown state.

[0035] During the specific operation, the lifting drive mechanism 13 drives the rubber driving wheel 43 to press against the surface of the brake disc 14, and then uses the static friction to drive the brake disc 14 to rotate, thereby realizing the rotation of the sprocket connected to the connecting shaft 44. This method avoids the efficiency loss in traditional manual operation, and at the same time directly transmits mechanical power to the sprocket, reducing the energy consumption and time waste in the intermediate links. The driving motor 4 is controlled by the electronic control box 8, which can realize both forward and reverse rotation of the sprocket, ensuring flexible and efficient operation of the turning machine.
