AI Technical Summary

Technical Problem

After settlement is detected, existing wind turbine foundations require manual reinforcement, during which settlement can easily continue and cannot be controlled in a timely manner, especially in remote or geologically unstable areas where the risk is greater.

Method used

Design a settlement monitoring device for wind turbine foundation structure. The device uses displacement sensors to monitor in real time and automatically responds through support components. It combines grouting components to achieve temporary reinforcement. The device includes a fixed cylinder, settlement components, support components, displacement sensors, and grouting channels to realize an automated process of monitoring and reinforcement.

Benefits of technology

It enables real-time monitoring and automatic reinforcement of wind turbine foundation settlement, stopping further settlement within minutes, avoiding safety accidents, buying time for manual reinforcement, simplifying operation procedures and extending the life of the device.

Abstract

The invention relates to the technical field of wind power generation, in particular to a wind driven generator foundation structure settlement monitoring device which is characterized in that fixed barrels are uniformly distributed around a tower barrel, grouting channels are arranged in the fixed barrels, settlement assemblies are arranged in the corresponding fixed barrels respectively, and the settlement assemblies are connected with the outer wall of the tower barrel; the fixed cylinder can move downwards along the axial direction of the fixed cylinder along with the settlement of the tower cylinder; the displacement sensors are respectively arranged in the corresponding fixed cylinders and are used for detecting the downward moving distance of the settlement assembly; the supporting assemblies are arranged in the corresponding fixing cylinders correspondingly, the supporting assemblies move upwards in the axial direction of the fixing cylinders to support the sedimentation assembly, and the supporting assemblies move downwards in the axial direction of the fixing cylinders to reset. One end of each grouting piece is communicated with the corresponding grouting channel, and the other end of each grouting piece extends towards the lower part of the tower drum and is used for filling a gap below the tower drum with a reinforcing material from the periphery of the tower drum, so that further development of settlement can be effectively prevented, and safety accidents such as tower drum inclination and equipment damage caused by continuous expansion of settlement are avoided.
