Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a yaw drive repair and debugging device based on a wind turbine. Background Technology

[0002] Wind energy is the most technologically mature and fastest-growing clean energy source among renewable energy sources, and it also has the greatest potential for large-scale development and commercialization. It is generated through wind turbines, which use wind power to rotate the turbine blades. A speed increaser further accelerates the rotation, causing the generator to produce electricity. Currently, most wind turbines use 2-4 sets of inputs with yaw motors and reducers to provide greater driving torque. This results in large footprints and high costs. Due to time differences in signal input, yaw asynchrony occurs. Furthermore, the direction of force on the impeller is not fixed, leading to significant turbine shaking and noise during yaw motor start-up and shutdown. Frequent collisions and friction at the gear or friction wheel mating surfaces also affect service life. When wind speeds are too high, the turbine blades rotate at high speeds, and once a certain speed is reached, the turbine cannot be stopped, easily causing runaway and damage. Therefore, we designed a yaw drive repair and debugging device based on a wind turbine unit. Utility Model Content

There are several bearing balls 3, which are circumferentially distributed inside the rotation limiting groove 2. The bearing balls 3 and the rotating ring 4 are connected by rotation. The first drive motor 8 and the repair and adjustment gear 9 are connected by drive. There are two first mounting side plates 7, which are symmetrically distributed on both sides of the top of the first limiting connecting ring 1. The two first mounting side plates 7 have the same structure. The repair and adjustment gear 9 and the main gear turntable 6 are connected by meshing. There are several connecting rods 5, which are circumferentially distributed between the rotating ring 4 and the main gear turntable 6.

[0020] In the implementation plan, the rotation of the repair and debugging gear 9 is directly controlled by the first drive motor 8 on the first mounting side plate 7 on both sides of the first limiting connecting ring 1. This enables yaw drive repair operation for the main gear turntable 6, and synchronous rotation transmission operation on both sides, improving the transmission repair efficiency of the device. The rotation of the main gear turntable 6 can drive the rotating ring 4 to rotate inside the rotation limiting groove 2. The rotation angle of the rotating ring 4 relative to the power spindle 12 is used to achieve the correction operation. The correction is achieved through the cooperation between the first limiting connecting ring 1 and the second limiting connecting ring 11, ensuring the correction operation at different points of the power spindle 12, thereby further improving the correction efficiency of the device.

[0021] Example 2:

[0022] Please see Figure 1-4This utility model provides a technical solution: a yaw drive repair and debugging device based on a wind turbine generator set, including a yaw drive repairer 13 disposed on one side of a first limiting connecting ring 1, a control panel 14 fixedly mounted on the top of one side of the yaw drive repairer 13, a data display 15 fixedly mounted on one side of the top of the control panel 14, a control setting disk 16 disposed on one side of the top of the control panel 14, a first motor control connection line 17 fixedly connected between a first drive motor 8 and the yaw drive repairer 13, second mounting side plates 18 fixedly connected to the top of both sides of the second limiting connecting ring 11, a second drive motor 19 fixedly mounted on the bottom of one side of the second mounting side plate 18, a second motor control connection line 20 fixedly connected between the second drive motor 19 and the yaw drive repairer 13, the connection relationship between the first drive motor 8 and the yaw drive repairer 13 is a power control connection, and the connection relationship between the second drive motor 19 and the yaw drive repairer 13 is a power control connection.

[0023] In the implementation scheme, the control panel 14 on the yaw drive repairer 13 directly controls the starting operation of the first drive motor 8, and simultaneously controls the starting operation of the second drive motor 19.

The yaw drive repairer 13 directly controls the use of the first limit connecting ring 1 and the second limit connecting ring 11 to ensure the uniformity of the correction of the device, thereby ensuring the correction quality of the device.

[0024] Working principle:

[0025] By setting the first drive motor 8 on the first mounting side plate 7 on both sides of the first limit connecting ring 1, the rotation of the repair and debugging gear 9 is directly controlled. The yaw drive repair operation is realized for the main gear turntable 6, and the rotation transmission operation is realized on both sides simultaneously, which improves the transmission repair efficiency of the device. The rotation of the main gear turntable 6 can drive the rotating ring 4 to rotate inside the rotation limit groove 2. The rotation angle of the rotating ring 4 relative to the power spindle 12 is used to realize the correction operation. The correction is realized through the cooperation between the first limit connecting ring 1 and the second limit connecting ring 11, ensuring the correction operation for different positions of the power spindle 12, thereby further improving the correction efficiency of the device.

The data display 15 on the control panel 14 facilitates data control and display. The control setting panel 16 allows for the versatility of the yaw drive repairer 13, enabling periodic control of the start-up of the first drive motor 8 and the second drive motor 19, and periodic correction of the power spindle 12 to ensure the stability of the correction. The yaw drive repairer 13 also directly controls the use of the first limit connecting ring 1 and the second limit connecting ring 11, ensuring the uniformity of the correction and thus guaranteeing the quality of the correction.
