Abstract

The invention relates to the underwater testing field, especially relates to a underwater digital ultrasonic flaw detector based on the underwater robot (ROV), the flaw detector is composed of a marine device and a underwater device, the two are connected by a communication cable, wherein the underwater device includes a water tight probe, an ultrasonic signal transmitting and receiving circuit, the marine device includes a ultrasonic waveform oscilloscope, the signal detected by the water tight probe is transferred to the ultrasonic waveform oscilloscope by the ultrasonic signal transmitting and receiving circuit and is displayed, the device is suitable for divers to carry and can acquire high quality images, the cost is low, which can guarantee quality and testing speed of visual investigation, and can be used in muddy water and various waters.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to an underwater digital ultrasonic flaw detector based on an underwater robot (ROV). Background technique [0002] Underwater nondestructive testing technology is a new technology developed with the rise of underwater engineering. In recent years, due to the sharp increase of offshore facilities, such as submarine pipelines and production platforms, how to ensure the safe operation of offshore facilities is very important. In addition, the underwater monitoring of large ships has also received more and more attention. At present, the widely used underwater non-destructive testing methods mainly include: visual inspection method, ultrasonic thickness measurement and ultrasonic flaw detection. Underwater ultrasonic flaw detection is an important content of underwater detection, and it is the main means to find internal defects of underwater metal structures. Using underwater rob...
