AI Technical Summary
Existing wind turbine vibration detection devices are inconvenient to install, difficult to adjust in position, and involve cumbersome multi-dimensional detection operations that affect detection accuracy, making it difficult to meet the actual needs of online wind turbine vibration monitoring.
The online vibration detection device for wind turbines employs a magnetic base, a combination ring, a traveling mount, and a measuring component. The magnetic base is quickly fixed to the bearing housing, the combination ring provides a moving track, the traveling mount can be locked in any position, and the sensor of the measuring component can be adjusted in direction and position to achieve multi-dimensional vibration detection.
It enables rapid installation, flexible adjustment, and multi-dimensional detection, improving detection accuracy and fault diagnosis accuracy while avoiding damage to equipment structure and complex operation.
