AI Technical Summary

Technical Problem

Existing methods for monitoring the tilt and settlement of wind turbines have problems such as reflectors being easily rained on and accumulating dust, leading to large errors and inaccurate monitoring results.

Method used

Design a wind turbine settlement and tilt angle monitoring device, which adopts a tilt angle measuring mechanism and a settlement measuring mechanism. It is fixed inside the tower by a central hanging component and a central distance sensor. The central distance sensor is always vertically downward. Combined with the left and right components, it monitors the settlement depth. The signal is reflected by the lower plate and the left and right plates to achieve accurate monitoring.

Benefits of technology

It enables real-time and precise monitoring of wind turbine foundation settlement and tower tilt angle, improving the reliability and accuracy of monitoring, reducing monitoring costs, minimizing manual intervention, and increasing work efficiency.

Abstract

This application relates to the field of wind turbine monitoring technology, specifically disclosing a wind turbine settlement and tilt angle monitoring device and method. The wind turbine settlement and tilt angle monitoring device includes a tilt angle measuring mechanism installed inside the wind turbine tower. The tilt angle measuring mechanism includes an upper support, a lower plate, a central sag bracket, and a central distance sensor. The lower plate is perpendicular to the axial direction of the tower. The upper support has a circular groove with a circular hole at the bottom. The central sag bracket has a central ball head, a central sleeve, and a central counterweight, fixedly connected from top to bottom. The central ball head is installed in the circular groove. The central distance sensor is fixed to the central counterweight. Under the influence of the weight of the central counterweight, the central ball head rotates around its center, ensuring that the signal emitted by the central distance sensor is always vertically downward. Regardless of the tower's tilt direction, this device can accurately monitor the wind turbine's tilt angle.
