The number and capacity of offshore wind power facilities are growing rapidly worldwide. Data as of 2023 show that the capacity of offshore wind power facilities has reached 31.89 million kilowatts. However, the problem of corrosion is a huge challenge currently faced by offshore wind power facilities, and it has caused many accidents. At present, the corrosion detection of offshore wind power facilities still uses manual climbing, ultrasonic technology, infrared technology, etc. to measure the coating thickness and rust condition for detection. However, these detection methods require manual operation, which is more dangerous, and the cost and operation time are relatively long. This project is mainly a design plan for an unmanned platform. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described below.

[0025] like Figure 1-6 As shown, the global adaptive offshore wind power equipment corrosion monitoring unmanned platform of this embodiment includes a UAV body 1 carrying the platform, a detection device 3 and a retractable mechanical arm 2 for mounting and adjusting the detection device. The mechanical arm is mounted under the belly of the UAV body, and the detection device 3 is fixed at the top movable end of the mechanical arm. The UAV body 1 includes a UAV wing 11, a first motor 12, a carbon fiber frame 13, a UAV control room 14, a fixed landing gear device 15 and a fixed landing gear 16. The UAV wing 11 and the first motor 12 are assembled and fixed on the carbon fiber frame 13. The carbon fiber frame 13 is installed around the UAV control room 14. Landing devices are arranged on both sides of the UAV control room 14, and the landing devices include a fixed landing gear device 15 and a fixed landing gear 16. The UAV control room 14 is provided with a camera 17. The mechanical arm 2 includes an upper rack 21 and a lower rack 22 corresponding to the upper rack 21. The upper rack 21 and the lower rack 22 are connected and driven by a gear 23. The movable end of the upper rack 21 is fixed with a detection device 3. The gear 23 is connected to a second motor 24, the second motor 24 is connected to a single-chip microcomputer, and the single-chip microcomputer is connected to a battery. A shell 25 is provided on both sides of the upper rack 21 and the lower rack 22. The shell 25 is connected by a metal connecting frame 26. The second motor 24 is embedded on one side of the shell 25, and a battery is hung on the other side. The battery is placed in a groove formed by a battery lower bracket 27 and a battery side bracket 28. The battery lower bracket 27 and the battery side bracket 28 are fixed to one side of the shell 25 by studs. The detection device 3 is a thickness gauge for measuring the thickness of the coating.

[0026] This device mainly consists of three parts, namely, the UAV platform as a carrying platform, the mechanical arm 2 for adjusting the position of the detection equipment 3, and the detector for coating thickness measurement. In terms of structure, the mechanical arm 2 is mounted under the belly of the UAV body 1 through the connecting frame 26, and is fixed with six M3 screws. The top movable end of the rack on the mechanical arm 2 is connected to the coating thickness gauge by clamping and locking. The mechanical arm 2 controls the second motor 24 to drive the gear 23 to rotate through the single-chip microcomputer loaded in the single-chip microcomputer bracket 29, and can achieve two mechanical forms, namely the storage form and the extension form. The storage form is used on the ground and during transportation. The gear 23 drives the upper rack 21 and the lower rack 22 of the mechanical arm 2 to retract to the center, and the main body and the clamped coating thickness gauge are received together under the UAV body, which reduces the wind resistance of the UAV during flight to a certain extent and can ensure that the equipment does not touch the ground. The extended form is used during flight inspection. The robotic arm 2 is extended forward as a whole, and the upper rack 21 equipped with a coating thickness gauge is extended forward and moved to the lower front position of the drone. At the same time, the lower rack 22 will also move backward accordingly to ensure the stability of the center of gravity, which greatly increases the safety and stability of the drone during inspection.
