Description

Technical Field

[0001] This utility model relates to the field of structural safety monitoring technology, specifically to a safety monitoring device for offshore wind power booster stations and wind turbine support structures. Background Technology

[0002] With the increasing global demand for clean energy, offshore wind power is playing an increasingly important role in energy structure transformation due to its advantages such as stable resources and large installed capacity potential. To improve the power generation efficiency and system operation safety of offshore wind farms, booster stations are typically installed in the wind farms for centralized power transmission. Simultaneously, the wind turbine support structures also need to operate stably over the long term to ensure normal power generation. During long-term operation, the booster stations and wind turbine foundations are susceptible to structural risks such as corrosion, fatigue, and tilting due to the marine environment. Therefore, conducting condition monitoring of these critical infrastructures is a necessary means to ensure the safe operation of the system.

[0003] Currently, structural health monitoring technology has been widely applied to the safety management of land structures such as bridges and high-rise buildings. Some offshore wind farms have also introduced a system framework for sensor acquisition, communication transmission, and condition diagnosis to monitor the operating status of supporting structures. However, existing monitoring systems are mostly customized installations, with dispersed structures and low integration. Limited by the high humidity, high salt spray, strong corrosion, and remote deployment environment of the ocean, they suffer from problems such as significant signal interference, unstable communication, difficulty in maintaining power supply, and short maintenance cycles, making it difficult to achieve long-term, accurate, and automated monitoring goals. Furthermore, existing sensing solutions mostly focus on single strain or displacement monitoring, failing to comprehensively reflect the combined effects of structural stress, vibration, and the environment, thus remaining functionally limited.

[0004] Therefore, under complex marine environmental conditions, how to construct a highly integrated, fully functional, conveniently deployed, and adaptable safety monitoring device for booster stations and wind turbine support structures that meets the needs of offshore operations, and solve problems such as insufficient monitoring dimensions, discontinuous data acquisition, and unstable system operation, has become a key technical problem that urgently needs to be solved in the field of structural safety monitoring technology.

[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] Example 1

[0039] This utility model provides a safety monitoring device for offshore wind power booster stations and wind turbine support structures. The device is composed of a combination of multiple types of sensors, a modular mounting base with a suitable structure, an integrated signal acquisition and processing unit, an industrial-grade remote communication module, and an independent power supply system. It realizes multi-dimensional monitoring of the operating status of wind power foundation structures and remote data reporting, thereby improving the intelligent level of equipment operation and the structural safety assurance capability.

[0040] like Figure 1 As shown, the device includes a sensor monitoring component, a modular mounting base, a signal processing module, a remote communication module, and a power supply module. The overall structure is compact and suitable for installation on key parts such as load-bearing beams, pile legs, jacket foundation nodes, and tower bases of substations or wind turbines.

[0041] The sensor monitoring assembly includes a fiber optic strain sensor, a triaxial accelerometer, a tilt sensor, a corrosion monitoring sensor, and a temperature and humidity sensor, used to sense the structure's stress, vibration, attitude, corrosion status, and environmental parameters in real time. All sensors are connected to the signal processing module via lead cables.

[0042] The modular mounting base is used for the unified integration and installation of various sensors and signal cables, and provides a stable support structure. It is located on the surface of platform components or inside cavities, and has vibration isolation and protection functions. The signal processing module is located in the mounting base or connected to the central control unit via cable, and is used to complete data acquisition, filtering, limit judgment, and buffering. The remote communication module is used to upload data from the signal processing module to the shore platform or remote server via a wireless link. The power supply module provides a stable energy source for the system, using a combination of solar power and lithium battery energy storage, and has energy regulation and power protection functions.

[0043] The modular mounting base is made of salt spray resistant, high-strength composite material, making it suitable for long-term exposure to high-humidity and high-corrosion marine environments. The mounting base features a magnetic adsorption structure and threaded fixing holes on the outside, allowing for flexible adsorption or threaded fastening methods depending on the shape of the mounting surface. It is compatible with curved steel structures, flat components, or flange interfaces, enabling reliable installation and rapid replacement.

[0044] The mounting base features a partitioned internal structure with a rubber buffer layer and cable guide channels, ensuring the stability of sensor installation and the independence of cable signal transmission, thereby improving the overall vibration resistance and signal integrity of the monitoring device.

[0045] The signal processing module internally houses a low-power industrial microprocessor and integrates an analog-to-digital signal conversion module, a signal filtering circuit, a data buffer chip, and a threshold judgment logic unit. Specifically, the signal acquisition unit uniformly samples the analog inputs from various sensors, removes high-frequency noise and low-frequency drift through the filtering circuit, and then sends the samples to the judgment circuit.

[0046] The judgment circuit uses a hardware comparator and logic chip to compare the changing trends of parameters such as tilt angle, acceleration, and strain in real time, and determines whether there is a structural abnormality based on preset thresholds. If the set threshold is exceeded, the system will trigger a local alarm output and send an alarm signal to the remote communication module.

[0047] The signal processing module is also equipped with an RS485 interface and an Ethernet interface, which supports establishing stable communication with the shore-based local monitoring platform or maintenance terminal. It is also equipped with an EEPROM storage chip for non-volatile storage of operating parameters and monitoring history records.

[0048] The signal processing module is also equipped with a USB debugging port, allowing maintenance personnel to read parameters, debug on-site, and export records via laptops or mobile terminals, thus improving on-site operation and maintenance efficiency.

[0049] The remote communication module consists of a 5G-enabled cellular module and a LoRa communication unit, which can automatically switch communication modes according to network conditions and has link redundancy. The communication module is encapsulated in a metal protective housing, has IP68 waterproof and dustproof capabilities, and internally includes surge protection circuitry and a temperature control module.

[0050] The communication module's antenna employs a sealed external structure and connects to the signal processing module via a dedicated signal lead. Communication data is encrypted and uploaded using the TLS encryption protocol, ensuring the integrity and security of the monitoring data. This module supports communication modes including timed transmission, limit-triggered transmission, and remote request / response.

[0051] The corrosion monitoring sensor employs a three-electrode electrochemical measurement system, comprising a working electrode, a reference electrode, and an auxiliary electrode. Each electrode is made of a different metal and is installed near structural welds, in areas of alternating water levels, or in areas affected by sea splash, to measure changes in the potential difference of the material under the influence of seawater, thereby assessing the corrosion trend of the metal. This configuration effectively enhances the early detection capability of localized corrosion rates.

[0052] The modular mounting base features multi-channel lead-in conduits, and signal cables from different sensors are isolated and routed using independent insulating sleeves and fixing clamps to prevent signal cross-interference. The cable guide path incorporates a flexible support frame and an electromagnetic shielding layer to ensure signal stability and anti-interference capabilities during long-term operation.

[0053] The power supply module consists of solar panels, a lithium battery pack, and an energy management circuit. The solar panels use flexible monocrystalline silicon photovoltaic thin films with a scratch-resistant transparent coating, allowing them to be directly adhered to the booster station platform or the top of the equipment without the need for drilling or slotting. The lithium battery pack is composed of high-energy-density cells encapsulated in a sealed, pressure-resistant battery box.

[0054] The energy management circuit includes an MPPT (Maximum Power Point Tracking) module, a charge / discharge control chip, and a power switching module. It is used to automatically switch between solar and battery power supply modes under different weather and power supply conditions, while protecting the battery from overcharging, over-discharging, abnormal voltage, and abnormal temperature.

[0055] Even in a continuous dark environment, the power supply module can still ensure the stable operation of the entire device for no less than 72 hours.

[0056] In summary, this utility model, through the rational integration of multiple types of sensors, structurally compatible installation modules, intelligent signal processing systems, remote communication units, and energy management systems, forms a structural safety monitoring device with complete structure, comprehensive functions, and strong environmental adaptability. It fully supports online monitoring of the operating status of wind power booster stations and wind turbine support structures, providing solid support for improving the operational safety and intelligence level of offshore wind farms.

[0057] Example 2

[0058] Taking a coastal wind farm as an example, this wind farm is located in the sea area about 45 kilometers from the shore, with an installed capacity of 300MW, and is equipped with a booster station platform and 50 wind turbine generators. Considering the risks of corrosion, high humidity, vibration and settlement faced by offshore structures during long-term operation, the wind farm has deployed the safety monitoring device for the offshore wind power booster station and wind turbine support structure provided by this utility model at the jacket joint of the booster station, the connection between the pile legs and the deck, the base of the wind turbine tower, and the top surface of the platform.

[0059] During installation, workers secured modular mounting bases integrating sensor monitoring components to the joints between the jacket support columns and trusses, using a combination of magnetic and threaded installation methods to accommodate different structural surfaces. Solar panels were installed on the unobstructed area above the substation platform and connected to the internal power supply module via multi-core waterproof cables. Once powered on, fiber optic strain sensors acquired real-time truss stress data, triaxial accelerometers recorded the vibration response of the wind turbine during operation, tilt sensors monitored changes in the substation's attitude, corrosion monitoring electrodes monitored the structural corrosion trend over the long term, and temperature and humidity sensors provided feedback on the internal environmental conditions of the cabin.

[0060] After the collected structural status data is initially judged and cached by the signal processing module, it is uploaded to the shore-side monitoring platform via the 5G communication module, realizing remote real-time monitoring and intelligent alarm of the substation's structural health. Since the system began operating three months ago, the equipment has been working stably without manual intervention, and the data transmission has been complete. It successfully identified an abnormal displacement at a bolt connection point on the pile leg and triggered a maintenance plan in advance, preventing structural fatigue expansion and significantly improving the operational safety and maintenance efficiency of the wind farm.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
