Description

Technical Field

[0001] The invention belongs to the field of wind turbine maintenance equipment, and in particular relates to an offshore wind turbine base crack detection device based on a flexible waterproof membrane sensor. Background Art

[0002] As a clean and renewable energy source, the development and utilization of wind energy will not emit greenhouse gases such as carbon dioxide, thereby significantly reducing air pollution and the greenhouse effect, and helping to address global climate change issues. Offshore wind turbines can use ocean wind energy to generate electricity. This low-carbon and environmentally friendly energy supply method is of great significance for promoting the optimization and transformation and upgrading of energy structure. About 70% of the earth's surface is covered by the ocean, and the ocean wind energy resources are extremely rich, and the wind speed at sea is more stable and strong than that on land. This means that the continuous and stable power generation of offshore wind turbines can provide a more reliable power supply for the power grid and improve the stability and reliability of the power system. Offshore wind turbines play an important role in solving energy problems in terms of clean and low-carbon, rich resources, promoting economic development, alleviating the imbalance of energy distribution, promoting scientific and technological innovation, and reducing the impact on the ecological environment. With the continuous advancement of technology and the increase in global demand for clean energy, offshore wind turbines will play a more important role in the future.

[0003] The underwater steel foundation structure of offshore wind turbines can ensure that offshore wind turbines maintain a stable operating state in a complex and changeable marine environment due to its good rigidity and strength. It can effectively resist the erosion and impact of natural forces such as waves, tides, and wind currents, and ensure the safety and stability of wind turbine towers and blades. In deep sea or sea areas with strong winds and waves, the steel foundation structure can withstand huge loads from the marine environment, including wind, water flow, wave force, etc., providing a solid support platform for wind turbines. Stable foundation support can ensure that wind turbines operate under optimal conditions, thereby improving power generation efficiency and power quality. This helps to reduce operating costs and improve economic and social benefits. However, although the underwater steel foundation of offshore wind turbines is coated with an anti-corrosion layer, it is easy to cause the anti-corrosion layer to fall off due to the impact of waves or floating objects, and the corrosion effect of seawater is enhanced, cracks will occur, and regular inspections are required. Nowadays, some detection equipment mostly uses electronic detection components or observes through cameras. These solutions, due to the use of electronic components, will be soaked in seawater and cause short circuits when operating at sea.

It solves the problem that the existing offshore wind turbine steel foundation inspection equipment cannot work stably, is prone to short circuit and requires repeated manual underwater inspection.
