Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power submarine cable monitoring, in particular to an automatic inspection device for monitoring sensors for dynamic submarine cable monitoring of offshore wind power. Background Technique

[0002] Due to the decreasing economically exploitable wind resources on land, the global construction of wind farms has shown a trend of developing from land to offshore. Compared with onshore wind power, the energy benefit of wind energy resources in offshore wind power is 20% to 40% higher than that of onshore wind farms. It also has the advantages of not occupying land, high wind speed, less dust, large power generation, stable operation, and zero dust emission. At the same time, it can reduce the wear of the unit and extend the service life of the wind turbine generator set, which is suitable for large-scale development. Offshore wind power usually needs to use submarine cables to transmit electric energy to onshore power consumption facilities. However, submarine cables are affected by complex external factors such as water flow, temperature, and pressure in the marine environment, and their postures will change dynamically. Therefore, regular inspections are required to ensure that the dynamics of offshore wind power submarine cables do not change excessively.

[0003] The utility model with the authorized announcement number of CN214152007U discloses an intelligent monitoring and warning system for offshore wind farms, including a ship traffic management module, including an AIS module and a communication module.

[0004] Adopting the above technical solution, it is possible to monitor whether the submarine cable is working properly, whether the navigating ships will affect the submarine cable, the water depth of the ships and whether their anchoring will affect the submarine cable. If there is a risk of an accident, the communication module is used to warn the ships to reduce the occurrence of accidents. However, in the above technical solution, the traditional dynamic inspection of offshore wind power submarine cables mainly relies on fixed-point sensors and manual inspections, which have problems such as poor real-time performance, incomplete data coverage, and high maintenance costs, and cannot automatically and real-time inspect the dynamics of offshore wind power submarine cables more accurately and conveniently, affecting the use safety of offshore wind power submarine cables.
