Description

Technical Field

[0001] The present invention belongs to the technical field of fan detection, and particularly relates to a stable and portable corrosion detection device for offshore wind turbines. Background Art

[0002] Offshore wind turbines are exposed to complex marine environments for a long time and are eroded by various factors such as salt spray, humidity, and sea waves, resulting in corrosion on the surface of the wind turbines. This corrosion not only seriously affects the appearance of the wind turbines but also gradually erodes the structure of the wind turbines, shortening their operating life. Therefore, in order to ensure the normal operation of the wind turbines, it is necessary to periodically detect the corrosion on the surface of the offshore wind turbines. However, the corrosion detection of offshore wind turbines is not an easy task; since the wind turbines are located offshore and far from land, the detection work often needs to be carried out in complex marine environments. In addition, corrosion cracks are often encountered in actual detection. These cracks are small and difficult to directly observe, making it impossible for conventional cameras to capture clear images. This brings great difficulties to the evaluation of the corrosion level. More importantly, the offshore working environment is more severe than the onshore working environment. The wind force level offshore is higher and the waves are rough, which all increase the difficulty and risk of the detection work. In such an environment, the quality of the visual images obtained is often low, and problems such as blurred and distorted images are common. This directly leads to large errors in the evaluation of the corrosion level and makes it difficult to accurately judge the corrosion degree of the wind turbines. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present utility model provides a stable and portable corrosion detection device for offshore wind turbines. The stable and portable corrosion detection device for offshore wind turbines can be operated by hand, has better stability, and can collect images of corrosion cracks, and the collected images have higher precision, thus being beneficial to improving the detection efficiency.

[0004] The technical solution of the present utility model to solve the above technical problems is:

[0005] A stable and portable corrosion detection device for offshore wind turbines includes an image acquisition device and a linear driving device for driving the image acquisition device to perform linear motion.

[0019] Figure 4 It is a structural diagram of a linear drive device. Specific implementation manners

[0020] The present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the implementation manners of the present utility model are not limited thereto.

[0021] See Figures 1 - 4 , the stable and portable corrosion detection device for offshore wind turbines of the present utility model includes an image acquisition device and a linear drive device for driving the image acquisition device to perform linear motion. Among them, the image acquisition device includes a mounting base 4, an endoscope 6 provided on the mounting base 4, and a telescopic drive mechanism for driving the endoscope 6 to extend and retract. Among them, the diameter of the endoscope 6 is 8 mm, which enables the lens of the endoscope 6 to easily enter the narrow gaps of the tower barrel and reach areas that are difficult for conventional cameras to reach, so as to collect more comprehensive and detailed image data, and thus solve the problem that conventional cameras cannot obtain high-quality pictures when shooting in gaps; a stability maintaining device 3 is further provided between the mounting base 4 and the drive end of the linear drive device, where the stability maintaining device 3 is a three-axis gimbal anti-shake stabilizer or a four-axis anti-shake gimbal, and the above three-axis gimbal anti-shake stabilizer or four-axis anti-shake gimbal can be realized by using existing devices; this enables the stable and portable corrosion detection device for offshore wind turbines of the present utility model to ensure the stable operation of the image acquisition device even in a slightly shaking sea breeze environment;

[0022] In this embodiment, the image acquisition device may further include a camera or a camera head provided on the mounting base 4.

[0023] See Figures 1 - 4 , the linear drive device includes a sleeve 2 and a linear drive mechanism for driving the sleeve 2 to perform linear motion. Among them, the end of the sleeve 2 is connected to the three-axis gimbal anti-shake stabilizer; the linear drive mechanism includes a linear drive motor 1 and a screw drive mechanism. Among them, one end of the screw 7 in the screw drive mechanism is connected to the main shaft of the linear drive motor 1 through a coupling; the screw nut 8 in the screw drive mechanism is installed in the inner cavity of the sleeve 2. The linear drive motor 1 drives the screw 7 to rotate, thereby driving the screw nut 8 and the sleeve 2 connected to the screw nut 8 to perform linear motion, and further driving the image acquisition device to perform linear motion.

[0024] See Figures 1 - 4, a sensor is provided inside the mounting base 4. The sensor includes a gyroscope, an accelerometer, a magnetometer, and an inertial measurement unit. Through the above sensors, data can be collected in real time, and an accurate anti-shake function can be achieved through the stability maintenance device 3 to ensure the stability of the captured image. In addition, an external interface 5 is provided on the mounting base 4 for connecting with various peripheral devices. The peripheral devices include expansion modules such as a display screen and a processor. This not only improves the overall performance of the device but also provides users with more function options and operation convenience.

[0025] See Figures 1 - 4 , an anti-corrosion coating is provided on the outer surface of the stable and portable offshore wind turbine corrosion detection device of the present invention, so that the stable and portable offshore wind turbine corrosion detection device of the present invention can be applied to the offshore wind turbine application environment to avoid corrosion damage to the device caused by seawater and wind loads.

[0026] See Figures 1 - 4 , the telescopic driving mechanism includes a sleeve and a rotary motor for driving the sleeve to rotate. Among them, the outer cylindrical surface of the sleeve is rotatably connected to the mounting base 4, and the endoscope 6 passes through the sleeve. A threaded connection is adopted between the outer cylindrical surface of the endoscope 6 and the inner cavity of the sleeve. The rotary motor is installed on the mounting base 4 and is connected to the sleeve through a transmission mechanism. The transmission mechanism is a gear transmission mechanism or a belt transmission mechanism. By driving the sleeve to rotate through the rotary motor, the endoscope 6 is driven to perform a telescopic movement (similar to a lead screw transmission mechanism). Since the endoscope 6 is a flexible part, it can be bent freely, so that the endoscope 6 can enter the narrow gaps of the tower barrel and capture areas that are difficult for conventional cameras to reach.

[0027] Finally, a handheld part is provided in the stable and portable offshore wind turbine corrosion detection device of the present invention to facilitate the operator to hold and operate.
