Description
technical field [0001] The invention belongs to the field of pipeline leakage detection, in particular to an underwater gas transmission pipeline leakage detection experimental platform. Background technique [0002] Pipeline transportation has the advantages of safety, economy, quality assurance, and no pollution. With the continuous development of marine resources, various projects of submarine oil and gas pipelines are gradually increasing. People are paying more and more attention to the operation status and safety maintenance of submarine pipelines. While the underwater detection technology continues to develop, an experimental platform under ordinary laboratory conditions is needed to simulate the underwater environment to detect pipeline leaks, so as to improve the detection system to improve its performance and positioning accuracy. [0003] The existing underwater waveguide laboratory can simulate the complex situation of the seabed, but due to the actual situation ...
