Description

Technical Field

[0001] This utility model relates to the field of monitoring technology for offshore wind power infrastructure, specifically to a real-time assessment and alarm device for the safety status of offshore wind power support structures. Background Technology

[0002] Offshore wind power, as a renewable and clean energy source, has been widely used globally in recent years. Offshore wind turbines are typically installed on jacket, monopile, or gravity foundations, which bear a combination of loads from ocean wind, waves, currents, the turbine's own weight, and operational loads. Due to the complex and rapidly changing marine environment, wind turbine foundations need to maintain long-term stability and durability; therefore, real-time monitoring and safety assessment of their operational status are of great importance.

[0003] Existing monitoring methods for offshore wind turbine support structures primarily rely on deploying single sensors in limited locations to monitor localized stress, vibration, or tilt angles. Some systems wirelessly transmit monitoring data to shore-based or remote servers for centralized processing. While this achieves basic data collection, it suffers from problems such as sparse deployment, limited information dimensions, lack of local real-time analysis and feedback, and insufficient system resistance to environmental interference. Furthermore, some current monitoring equipment is highly dependent on power and communication conditions, making it difficult to meet the requirements for long-term stable operation in unattended offshore environments, resulting in significant delays in the timely detection and response to abnormal conditions in the support structure.

[0004] Based on the above, there is an urgent need for a structured monitoring device in the field of real-time monitoring of offshore wind power support structures that can integrate multi-parameter acquisition, local status determination, independent power supply and local alarm functions, so as to realize continuous tracking of the status of the support structure and timely response to abnormal conditions, thereby improving the safety of offshore wind turbine foundation operation and maintenance management efficiency.

It is suitable for jacket type, monopile and pile-raft composite wind power foundation structures.

[0042] like Figure 1 As shown, the device is installed on the outer surface of the wind power support structure 1 via an installation structure. The overall structure uses the main support plate as a carrier, and integrates various functional components into one unit through fastening connections. Externally, two or more annular clamps firmly fix the main support plate to the surface of the cylindrical foundation structure, forming a stable attachment platform.

[0043] Structural monitoring module 2 is located on the surface of the main support plate to sense the structural operating status. This module integrates multiple different types of sensor components, including accelerometers, strain gauges, tilt sensors, crack detection elements, and environmental parameter sensors (humidity, salt spray concentration, etc.), enabling multi-dimensional data acquisition of the support structure's status. The sensor locations are selected based on the structural stress and corrosion risk areas to ensure the representativeness and sensitivity of the monitoring data.

[0045] The alarm output module 4 is located on one side or below the edge control unit and consists of a high-brightness LED flashing component, a high sound pressure buzzer, and an output signal port. When the structural condition is abnormal, this module receives a signal from the control unit, immediately issues an audible and visual warning, and uploads the status signal to a remote platform or SCADA system via an industrial interface.

[0046] Power supply module 5 is installed at the top of the device, employing a wind-powered generator and flexible solar panels to form a wind-solar hybrid system for collecting ambient energy. The generated electricity is transmitted via cables to battery unit 6 for storage.

[0048] Example 2

[0049] like Figure 2 As shown, the modular logic of this invention is clear: the structural monitoring module acts as a signal source, sending various monitoring signals to the edge control unit; the control unit performs comprehensive signal processing and status judgment, and controls the alarm module to start and stop, while simultaneously achieving remote data output through a communication interface; the power supply module serves as the energy source, providing stable operating power to both the structural monitoring module and the edge control unit, ensuring the independence and continuity of the entire system. Distributed wiring is used between modules, providing good system redundancy and ease of maintenance.

[0050] In summary, the real-time safety status assessment and alarm device for offshore wind power support structures described in this utility model, through integrated structural design and collaborative operation of functional modules, achieves full-process monitoring functions from physical signal sensing and local data analysis to local alarm response and remote signal output. The device features a reasonable structural layout, flexible installation methods, clear module logic, and reliable operation, possessing excellent engineering application value.
