[0023] Embodiment 1: The present application provides a wind turbine slewing bearing ellipse correction device, comprising a wind turbine slewing bearing body 1; a mounting block 2 is provided at the bottom of the wind turbine slewing bearing body 1, a mounting base 4 is provided below the wind turbine slewing bearing body 1, a placement seat 7 is provided at the bottom of the mounting base 4, a slide rail 10 is provided at equal intervals on the surface of the placement seat 7, and a driving mechanism 11 is provided on one side of the slide rail 10;

[0024] The driving mechanism 11 includes an installation cavity 1101, an electric push rod 1102 and a driving block 1103. The installation cavity 1101 is evenly spaced on the surface of the placement seat 7. The electric push rod 1102 is fixedly installed inside the installation cavity 1101. The driving block 1103 is slidably installed on the surface of the electric push rod 1102. The surface of the installation base 4 is embedded with a displacement sensor 8. The bottom of the installation base 4 is fixedly installed with a slider 9, and the slider 9 is slidably installed inside the slide rail 10.

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the device is in use, the wind power slewing bearing body 1 is installed on the mounting base 4 through the mounting mechanism 6 and fixed inside the corresponding groove 5. When the wind power slewing bearing body 1 is subjected to external force, the slider 9 of the mounting base 4 at the bottom of the wind power slewing bearing body 1 slides radially inside the slide rail 10. When the displacement sensor 8 detects the radial dimensions of the wind power slewing bearing body 1 at different positions and transmits the data to the control system, the control system determines the ellipticity error of the wind power slewing bearing body 1 according to the preset roundness standard, and calculates the position and force that need to be adjusted. Then, the control system is turned on by the driving mechanism 11, and the driving block 1103 is driven by the electric push rod 1102 to slide on the surface of the placement seat 7, and the position of the slider 9 below the wind power slewing bearing body 1 is adjusted until the ellipticity error reaches the preset standard, so that the ellipticity of the wind power slewing bearing body 1 can be quickly detected and calibrated, thereby improving the overall performance and stability of the wind turbine generator set. Through the coordinated use of the displacement sensor 8 and the driving mechanism 11, the measurement, calculation and correction process can be automatically completed without manual intervention, thereby improving work efficiency and safety.

[0026] Further, a corresponding groove 5 is provided on the surface of the mounting base 4, and a mounting mechanism 6 is provided on one side of the corresponding groove 5. The mounting mechanism 6 includes a placement groove 601, an electromagnet 602, a spring 603 and a clamping block 604. The placement groove 601 is provided on one side of the corresponding groove 5, and the electromagnet 602 is embedded and installed on the inner wall of the placement groove 601. A spring 603 is slidably installed on one side of the placement groove 601, and a clamping block 604 is slidably installed on one side of the spring 603. The surface of the mounting block 2 is provided with clamping grooves 3 at equal intervals, and the size of the clamping block 604 matches the size of the clamping groove 3.

[0027] Specifically, Figure 1 , Figure 2 As shown, when personnel install the wind turbine slewing support body 1, they insert the installation block 2 set at the bottom of the wind turbine slewing support body 1 into the corresponding groove 5, so that the slot 3 on one side of the installation block 2 corresponds to the block 604, and then the electromagnet 602 is powered off through an external controller. After the electromagnet 602 is powered off and loses its magnetic force, the block 604 will pop outward under the elastic action of the spring 603, and then the block 604 can be bounced into the inner cavity of the slot 3, so that the wind turbine slewing support body 1 can be quickly installed on the surface of the installation base 4 for use. The wind turbine slewing support body 1 can be quickly installed through the installation mechanism 6. When personnel install and disassemble the wind turbine slewing support body 1, there is no need to use external tools to install it, which can improve the work efficiency and convenience of personnel in its disassembly and installation to a certain extent.

[0028] Working principle: The wind turbine slewing bearing body 1 is installed on the mounting base 4 through the mounting mechanism 6 and fixed inside the corresponding groove 5. When the wind turbine slewing bearing body 1 is subjected to external force, the slider 9 of the mounting base 4 at the bottom of the wind turbine slewing bearing body 1 slides radially inside the slide rail 10. When the displacement sensor 8 detects the radial dimensions of the wind turbine slewing bearing body 1 at different positions and transmits the data to the control system, the control system determines the ellipticity error of the wind turbine slewing bearing body 1 according to the preset roundness standard, and calculates the position and force that need to be adjusted. Then, the control system is turned on by the driving mechanism 11, and the driving block 1103 is driven by the electric push rod 1102 to slide on the surface of the placement seat 7, and the position of the slider 9 below the wind turbine slewing bearing body 1 is adjusted until the ellipticity error reaches the preset standard, thereby being able to quickly detect and calibrate the ellipticity of the wind turbine slewing bearing body 1.
