Problems solved by technology

The single-pile tower foundation used in wind power generators in the prior art is mainly composed of steel towers with anti-corrosion coatings. However, since the design life of offshore wind turbines is more than 25 years, in the harsh environment at sea, anti-corrosion coatings It is inevitable to fall off, and the steel structure is exposed to the highly corrosive seawater and marine atmosphere, which will damage the life of the structural foundation of offshore wind turbines, and even cause serious safety accidents. Therefore, it is particularly important to perform corrosion detection on the structure of offshore wind power foundations.

Embodiment 1

[0030] like figure 1 and figure 2 As shown, this embodiment introduces an online detection device for corrosion of offshore wind power monopile foundations in the tidal range zone. The foundation 1 passes through the ocean's sea mud area, full immersion area, tidal range area, and splash area from bottom to top, until it enters and exits the atmosphere area; the detection equipment includes buoys 2 and buoys 2 installed on the outer periphery of the tower foundation 1 in the tidal range area. A plurality of waterproof cameras 3 are arranged on the top, and the lenses of each camera 3 are directed towards the tower foundation 1 in the tidal zone, so as to take images of the outer wall surface of the tower foundation 1 submerged in the tidal zone.

[0031] Through the above settings, the buoy can be moved up and down in the tidal range area according to the rising and falling tide of the sea surface, and the camera set on the buoy can take a comprehensive picture of the tower ...

Embodiment 2

[0042] like figure 1 and image 3 As shown, this embodiment introduces an online detection device for corrosion in the splash zone of an offshore wind power single pile foundation. The foundation 1 passes through the ocean's sea mud area, full immersion area, tidal range area, and splash area from bottom to top, until it enters and exits the atmosphere area; the testing equipment includes an annular platform 6 set on the outer periphery of the tower foundation 1 in the splash area, The ring-shaped platform 6 is installed on the tower foundation 1 through the lifting device; multiple waterproof cameras 3 are arranged on the ring-shaped platform 6, and the lens of each camera 3 faces the tower foundation 1 in the splash zone, so that the lifting device During the process of driving the annular platform 6 to move up and down, an image is taken of the outer wall surface of the tower foundation 1 in the splash area.

[0043] Through the above settings, the ring-shaped platform is...

Embodiment 3

[0062] like Figure 4 As shown, this embodiment is based on the first and second embodiments above, and also introduces an online detection system for corrosion of offshore wind power single pile foundations. The control server 16 of the entire offshore wind farm is set on the coast, and the towers of each wind power generator at sea There are controllers 14 inside, and each controller 14 is connected to the control server 16 through communication cables, so that two-way data transmission can be performed between the controller 14 and the control server 16, so that the offshore wind power described in the first embodiment above Corrosion signals in the tidal range zone of the offshore wind power single pile foundation detected by the on-line detection equipment for corrosion in the tidal range zone of the single pile foundation and detected by the camera 3 on the online detection equipment for corrosion in the splash zone of the offshore wind power single pile foundation descri...

Abstract

The invention discloses on-line detecting equipment for tidal range zone corrosion in an offshore wind power single-pile foundation. A wind power generator erected on the sea comprises a tower barrelfoundation extending from the seabed to the sea surface, and the vertically cylindrical tower barrel foundation penetrates through a mud zone, a full immersion area, a tidal range zone and a splash zone of the sea in sequence from bottom to top to an atmospheric zone; the detecting equipment includes a buoy installed on the outer periphery of the tower barrel foundation of the tidal range zone ina sleeving mode, and the buoy is provided with a plurality of waterproof-treated cameras, and the lenses of the cameras are oriented toward the tower barrel foundation in the tidal range zone to perform image shooting on the outer wall surface of the tower barrel foundation immersed in the tidal range zone. Through the arrangement, the buoy can be subjected to corresponding lifting and lowering displacement in the tidal range zone along with the rising tide and falling tide of the sea surface, so that the cameras arranged on the buoy can fully capture the tower barrel foundation of the tidal range zone, and the purpose of accurately obtaining the corrosion detection information of the tube barrel foundation in the tidal range zone is achieved. Meanwhile, the on-line detecting equipment issimple in structure, simple in method and remarkable in effect, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to wind power generation equipment installed on the sea, in particular to an on-line detection device for corrosion in the tidal range zone of a single pile foundation of offshore wind power. Background technique [0002] In the current severe situation where fossil energy resources such as coal and oil are increasingly scarce, and greenhouse gas emissions threaten the living environment of human beings, wind energy, as a green energy resource that can be continuously regenerated and sustainable in nature, is characterized by its huge reserves, wide distribution, and unlimited potential. Pollution and other advantages are increasingly valued by countries around the world. Since the world's first offshore wind farm was built in Denmark in 1991, offshore wind power has become a key field of renewable energy development in the world. After more than 20 years of development, offshore wind power technology has become increasingly matu...
