Problems solved by technology
The construction of a large number of offshore oil and gas projects has put forward new requirements for the efficiency and quality of underwater pipeline maintenance operations. Traditional manual maintenance operations can no longer meet the needs. Underwater ultrasonic flaw detection robots are an inevitable choice for realizing the opening of the ocean.
[0003] However, the existing ultrasonic flaw detection robot can only perform ultrasonic flaw detection operations on pipelines of the same specification, which reduces the scope of use of flaw detection devices and is inconvenient to use

The invention relates to the technical field of ultrasonic flaw detection, in particular to an ultrasonic flaw detection device suitable for underwater vertical pipelines with different diameters, which comprises a pincerlike mechanical arm assembly, a guide wheel assembly and an ultrasonic flaw detection box assembly, the pincerlike mechanical arm assembly comprises two three-axis mechanical arms, and the two three-axis mechanical arms are connected to the left side and the right side of the underwater robot correspondingly and used for fixing the robot. The guide wheel assembly is installed at the tail end of the pincerlike mechanical arm assembly and used for guiding movement of the pincerlike mechanical arm assembly and switching movement modes. The ultrasonic flaw detection box assembly is connected with the four-fork end of the pincerlike mechanical arm assembly and used for confirming whether the pincerlike mechanical arm assembly is unfolded to a proper angle or not and completing ultrasonic flaw detection and data processing of the pipeline. The ultrasonic flaw detection device is fixedly mounted with an underwater robot, so that ultrasonic flaw detection operation on underwater pipelines with different diameters can be realized, and the application range of the ultrasonic flaw detection device is greatly expanded; the robot can be independently disassembled and assembled, and other work of the robot is not affected.
Description
technical field [0001] The invention relates to the technical field of ultrasonic flaw detection, in particular to an ultrasonic flaw detection device suitable for underwater vertical pipelines with different diameters. Background technique [0002] At present, in the face of new changes in the energy supply and demand pattern and new trends in international energy development, my country continues to promote the development of marine resources. The construction of a large number of offshore oil and gas projects has put forward new requirements for the efficiency and quality of underwater pipeline maintenance operations. Traditional manual maintenance operations can no longer meet the needs. Underwater ultrasonic flaw detection robots are an inevitable choice to realize the opening of the ocean. [0003] However, the existing ultrasonic flaw detection robot can only perform ultrasonic flaw detection operations on pipelines of the same specification, which reduces the scope o...
