Bionic robotic fish for monitoring corrosion condition of underwater pile foundation of offshore wind plant

Abstract

The invention relates to the technical field of wind power plant operation and maintenance management, in particular to a bionic robotic fish for monitoring the corrosion condition of an underwater pile foundation of an offshore wind power plant. Comprising a bionic robotic fish body, a power propeller, a buoyancy regulator, a sinking and floating air bag, an air compressor, a processor, a power manager, a multi-beam detection sonar and a sound velocity profiler are regularly arranged in the bionic robotic fish body, and a measuring ship, a master control machine room and a satellite reference / moving station are arranged outside the bionic robotic fish body. According to the design, original underground diving and autonomous cruising can be achieved, and the influence of stormy waves is reduced; by carrying the multi-beam sonar, the underwater three-dimensional image of the wind power plant can be obtained, the corrosion condition of the wind power plant can be accurately measured, a repair scheme can be quickly and accurately customized, and the operation and maintenance management cost of the wind power plant is reduced; monitoring data can be acquired nearby and calculated, the monitoring work efficiency and accuracy are improved, defects of the wind power plant are found and repaired in time, and the power generation efficiency and safety of the wind power plant are guaranteed.

Description

Technical field [0001] The present invention relates to the field of wind farm operation and maintenance management technology, specifically, to a bionic robotic fish for monitoring the corrosion of underwater pile foundations in offshore wind farms. Background [0002] China's offshore wind energy resources are abundant, and are mainly distributed in the southeast coastal areas with developed economy, strong power grid structure and lack of conventional energy, so offshore wind farms came into being. Offshore wind farms mostly refer to offshore wind power with a water depth of about 10 meters, which has the advantages of not occupying land resources, basically not affected by terrain and landform, higher wind speed, larger single unit capacity of wind turbines, and higher annual utilization hours compared with onshore wind farms. However, the technology required to build offshore wind farms is higher than that of on-road wind farms, and offshore wind farms are not only expensiv...

AI Technical Summary

Problems solved by technology

However, the technology required to build offshore wind farms is higher than that of on-road wind farms. Offshore wind farms are not only expensive to build, but also expensive to operate and maintain

The main components such as pile foundations and submarine cables of offshore wind farms are immersed in seawater for a long time. It is very easy to damage the seabed, pile foundations or submarine cables due to wave erosion and seawater corrosion, which not only affects the power generation efficiency, but also has a large However, once the components of the wind farm are damaged due to serious defects, it is difficult to repair and cause a lot of economic losses

However, due to the strong wind and waves at sea, conventional underwater detection devices are easily affected by the wind and waves and deviate from the preset route. Not only is it difficult to accurately and quickly monitor the corrosion of the underwater pile foundation of the wind farm, but it is also difficult to manage
