Description

Technical Field

[0001] The utility model relates to the technical field of fan settlement monitoring circuits, and more specifically, to an online intelligent monitor for fan settlement. Background Art

[0002] The hub heights of modern large-scale wind turbines generally exceed 80 meters. The tall wind power towers are prone to violent shaking and even deformation under harsh climate conditions, such as strong winds and typhoons. The tall structure of the wind turbine makes it very sensitive to minor uneven settlements of the foundation, which may cause the tower to tilt, and large horizontal offsets to occur in the nacelle, hub, blades, etc. Severe uneven settlement of the foundation may cause the fan to tilt significantly, and even induce the occurrence of tower collapse accidents.

[0003] The automated online monitoring system for uneven settlement can collect data in real time, helping the administrator to detect abnormal situations in time and carry out effective early warning and intervention. This real-time monitoring feature is particularly important for wind turbines because minor changes in the foundation structure can have a significant impact on overall safety. By automatically collecting data, errors that may occur in manual operations are avoided, so the accuracy and reliability of the data are relatively high. This is crucial for accurately evaluating the settlement of wind turbines. Although the traditional manual inspection method is simple and easy to implement, the manual labor intensity is high, and safety hazards may not be discovered in time due to the carelessness and negligence of the staff. The automated online monitoring system can significantly reduce the frequency and intensity of manual inspections and improve work efficiency. At the same time, the online monitoring system can store historical data, which is convenient for users to analyze, compare, and trace. This has important reference value for analyzing the settlement trend of wind turbines and predicting future settlement situations. The automated online monitoring system can operate automatically, reducing the number of times and workload of manual intervention and improving the operation and maintenance efficiency.

[0004] With the rapid development of infrastructure construction, the geological conditions of the subgrade section are complex. Traditional manual monitoring can no longer meet the requirements of settlement monitoring in complex situations. Automated settlement monitoring needs to be collected in various special sections to meet the requirements, which is of great significance for the large-scale automated operation and maintenance management of wind farms.
