Embodiment 1

[0029] The present invention utilizes an artificial intelligence (AI) deep learning method, combined with optical fiber safety monitoring technology, and the actual measurement data of an ultra-high molecular weight polyethylene corrosion-resistant orbital ultrasonic sounder (multi-wave velocity), to achieve scouring of pile foundations (extreme events) Real-time coupling analysis with optical fiber safety monitoring results.

[0030] refer to figure 1 , an offshore wind power foundation safety monitoring platform based on real-time monitoring and AI analysis, by installing an orbital ultrasonic sounder on the foundation of the offshore wind turbine to scan the water depth around the pile foundation in real time, the sounder will obtain terrain data ; At the same time, through the real-time comparison of optical fiber safety monitoring data, the impact of seabed scour and wind power foundation is calculated. Through edge computing and AI deep learning, the regular scanning da...

Embodiment 2

[0041] refer to figure 2 , a marine wind power basic safety monitoring method, comprising the following steps:

[0042] Step 1. Use the first multi-wave velocity sounder 5 and the second multi-wave velocity sounder 6 to measure the water depth around the pile foundation in real time; use the fan safety monitoring system to monitor the vibration and displacement of the fan, and use the regular scanning device to collect The change data of the seabed of the wind farm as a whole (that is, the change of the regional seabed);

[0043] Step 2. Obtain real-time topographic data according to water depth, and conduct coupling analysis on real-time topographic data and optical fiber safety monitoring data; analyze the impact of extreme events on erosion and wind turbine vibration and regional sea conditions based on real-time topographic data and regular scanning data. Bed movement and change; analysis of the actual impact of scour on wind turbine pile foundations based on regional se...

Abstract

The invention discloses an ocean wind power foundation safety monitoring platform and a monitoring method. The monitoring platform comprises a first multi-wave-velocity depth finder and an integrated system, the output end of the first multi-wave-velocity depth finder is connected with the integrated system, the first multi-wave-velocity depth finder is installed on a first guide rail, and the first guide rail is installed on the peripheral face of a fan pile foundation; the multi-wave-velocity depth finder is used for measuring the water depth around the pile foundation and transmitting the water depth to the integrated system, topographic changes around the pile foundation are monitored in real time through an underwater double-track multi-channel ultrasonic depth finder, the scouring problem is reflected through data fusion and comparison with a regional AI technology for regular scanning measurement, the moving speed of a whole seabed is eliminated, and meanwhile, the influence of scouring on the safety of a fan is found by comparing actually measured safety data of the fan.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to foundation scour monitoring of offshore wind farms. Background technique [0002] As the most important part of the earth's water resources, the ocean contains huge renewable energy. Although offshore wind power started late, it has been developing rapidly in recent years due to the stability of sea wind resources and the characteristics of large power generation. At present, the development and utilization of offshore wind power is on the rise, which has greatly promoted the research on the ability of offshore structures to resist waves and tidal erosion. [0003] Offshore wind turbine foundation is an important infrastructure of offshore wind power and a supporting component of offshore wind turbines. The environment in which it is located is very harsh, and it not only bears the effects of various natural conditions, but also suffers from foundation e...
