Description

Technical Field

[0001] This utility model relates to the field of offshore wind power technology, specifically to a digital twin visualization monitoring device for offshore wind power support structures. Background Technology

[0002] Offshore wind power, as an important renewable energy development method, converts wind energy into electricity, offering advantages such as abundant resources, high power generation efficiency, and reduced carbon emissions. To ensure the long-term stable operation of wind turbines, the support structures in offshore wind farms must withstand complex marine environmental loads, such as wind loads, wave loads, and ocean current loads. Under these loads, the support structures are prone to fatigue, corrosion, and stress deformation. Therefore, real-time monitoring and condition assessment of the support structures are of great significance. The health status of the support structures directly affects the operational safety and maintenance costs of the entire wind power system.

[0003] Currently, monitoring of offshore wind turbine support structures primarily relies on traditional sensor deployment methods. This involves dispersing strain sensors, accelerometers, and other equipment to monitor the structural stress and vibration states. However, due to issues such as dispersed sensor deployment, delayed data processing, and insufficient environmental adaptability, existing systems often suffer from fragmented monitoring information, poor real-time performance, and a lack of system integration and visual management capabilities. Furthermore, traditional systems largely depend on periodic manual inspections, making it difficult to detect potential risks to the support structure in a timely manner, increasing maintenance difficulty and costs. In addition, the offshore environment places higher demands on equipment protection, independent power supply, and data communication capabilities; existing technologies still have significant room for improvement in long-term stable operation and remote intelligent monitoring.

[0004] To address the challenges of fragmented monitoring methods, insufficient data integration and real-time performance, and limited remote communication and independent power supply capabilities for offshore wind power support structures in complex environments, there is an urgent need to develop a highly integrated, real-time, and environmentally adaptable support structure health monitoring and visualization management device. This device would enable continuous dynamic monitoring of the health status of offshore wind power support structures and intelligent operation and maintenance support. Utility Model Content

[0011] A further improvement of this invention is that the central data processing unit is equipped with a data acquisition module, an edge computing module, and a data storage module arranged in functional compartments.

[0012] A further improvement of this invention is that the adaptive digital twin modeling module dynamically adjusts the virtual simulation model parameters of the support structure based on real-time force data, vibration data, and tilt data.

[0013] A further improvement of this utility model is that the solar panel in the power supply module is fixed to the top of the support structure by an aluminum alloy bracket, which can withstand a level 12 wind load and maintain an independent power supply capability for more than seven days in continuous rainy conditions.

[0014] A further improvement of this invention is that the energy storage battery pack is installed inside the protective enclosure, and the charging and discharging state of the battery is controlled by a charging and discharging management system to maintain the stable operation of the power supply system.

[0015] A further improvement of this invention is that the 5G communication module and the satellite communication module in the communication module adopt a redundant backup design, and automatically switch to the satellite communication link when the 5G communication is interrupted.

[0016] A further improvement of this invention is that the multifunctional visualization display terminal adopts a high-brightness touch screen with salt spray resistance treatment, and displays the stress distribution, vibration mode and environmental parameter change curves of the support structure based on three-dimensional dynamic graphics.

[0017] A further improvement of this invention is that the adaptive digital twin modeling module has a built-in intelligent learning unit, which can optimize the accuracy of simulation modeling based on historical monitoring data and improve the accuracy of the health status assessment of the supporting structure.
