Intertidal zone corrosion detection device for offshore wind turbine tower tube

Abstract

The invention discloses an intertidal zone corrosion detection device for an offshore wind turbine tower tube. Herein, encircling measurement is carried out through a combined floating element, so that the detection device adapts tower drums with different diameters and is convenient to disassemble and assemble; the device is characterized by comprising a baffle table, a floating element and a positioning rod, wherein the floating elements are connected end to end through bolts to form a semi-floating ring; the two semi-floating rings are connected through two telescopic positioning rods to form a whole floating ring; the baffle table is located above the whole floating ring. The positioning rod is connected with the baffle table; a floating block is arranged on the positioning rod; the tower crane intertidal zone monitoring device is simple in structure, convenient to assemble and disassemble, convenient for personnel to assemble, maintain and disassemble, and capable of performing camera monitoring on a tower crane intertidal zone along with tide fall, finding tower crane corrosion traces in time, performing maintenance treatment early, and ensuring the service life and equipmentsafety of the tower drum.

Problems solved by technology

[0002] Offshore wind power towers have been in harsh marine corrosion environments for a long time, and steel pipe piles that have been in the intertidal zone and seawater submerged areas for a long time are coated with anti-corrosion layers, but in the long-term environment of alternating dry and wet seawater, the anti-corrosion layer continues to deteriorate. Under the impact of sea waves and external floating objects, it is easy to peel off and fall off, causing the internal tower to be immersed in sea water. If it is not found and maintained in time, the corrosion of the tower will increase rapidly, and even cause damage to the overall structure of the wind turbine unit. Bengkai, and the existing notification number CN109868847A discloses an online detection device for corrosion of offshore wind power single pile foundations in the tidal range zone. The base of the tube 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 buoys installed on the outer periphery of the tower base in the tidal range area. Multiple waterproof cameras, the lens of each camera is facing the tower foundation in the tidal range area. Although this equipment can monitor the tower in real time, due to the huge diameter of the tower used for seawater wind turbines, the device is a whole Due to the unique structure, it is necessary to cooperate with the hoisting and installation of the tower during installation. At the same time, the structure size needs to be designed according to the diameter of the tower in advance, which has great limitations in use and is extremely inconvenient for subsequent maintenance and disassembly.
