Intelligent detector for submarine pipeline

Abstract

The disclosed detector comprises: a driver, a magnetic-leakage probe, a magnetic-leakage signal process device with a rotary coder, a power, an ultrasonic probe, and a ultrasonic signal processor with a roller carried a milometer all connected by gimbals in turn. This invention integrates both magnetic-leakage and ultrasound, realizes precise positioning to defect in pipeline, and can detect the defect and hidden danger all round.

Description

technical field [0001] The invention relates to a detector in the technical field of detection, in particular to an intelligent detector for submarine pipelines. Background technique [0002] Pipeline transmission is the main way to transport energy such as oil and natural gas. However, many pipeline networks have been used for decades, whether domestic or foreign, and pipeline leakage occurs from time to time. In particular, submarine pipelines, due to their extremely harsh working conditions, are more prone to corrosion, fatigue damage, or leakage accidents caused by potential internal defects in the pipeline developing into damage. If they are not repaired in time, this will inevitably cause huge economic losses and serious environmental pollution. Therefore, effective online detection of pipelines has become a top priority, but there is currently no effective online detection system for offshore submarine pipelines in China. At the same time, since the design and const...

Problems solved by technology

"Its shortcoming is that the detection device only records the time difference of the pulse reflection of the inner and outer walls. Once the pulse is judged incorrectly, due to the lack of original ultrasonic data, manual judgment cannot be performed again, and the reliability of the system is greatly reduced; the detection device only measures the pipeline Wall thickness, potentially dangerous defects such as cracks cannot be identified
