Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ultrasonic detection, more particularly to a non-contact ultrasonic detection unmanned plane. BACKGROUND

[0002] In the prior art, ultrasonic detection is usually used to detect internal defects.

[0003] Traditionally, there are two kinds of ultrasonic scanning devices: one is a two-axis or three-axis scanning mechanism for scanning a plane, which is used for C-scan imaging of regular-shaped workpieces; the other is a multi-axis detection device that is matched with a rotating shaft or uses a mechanical arm, which is used for detecting workpieces with non-planar or nonlinear surface curvature.

[0004] However, in practical applications, both of these methods are limited to detecting objects near the detection system, which is not suitable for in-service large aircraft detection. For example, aircraft maintenance units commonly use manual high-altitude operations to climb to the detection area to determine the specific detection of internal damage, which is undoubtedly a time-consuming and labor-intensive work with high risk to the operator.

[0005] For some narrow areas, personnel are difficult to reach due to body size restrictions, which can easily cause missed detection. In addition, since most large passenger planes or military aircraft are more than ten meters high or even higher, climbing operations are difficult to avoid and are dangerous. In view of the above problems, there are many ultrasonic detection devices on crawlers and unmanned planes at home and abroad, which usually use direct contact methods to apply coupling agents to the detected surface for contact detection. Although it is suitable for small areas, it is often time-consuming and inefficient for large-area detection, especially for non-contact parts such as J-20 stealth coating. There is currently no suitable method.

[0006] Therefore, how to provide a new non-contact ultrasonic detection unmanned plane that can detect large aircraft while using a non-contact detection method instead of manual scanning is a problem that needs to be solved by those skilled in the art. UTILITY MODEL CONTENT
