Pressure pipeline self-drifting ultrasonic inner detection intelligent ball

Abstract

The invention relates to the field of special equipment and aims at providing a pressure pipeline self-drifting ultrasonic inner detection intelligent ball with the characteristics of convenient operation and high detection precision. The pressure pipeline self-drifting ultrasonic inner detection intelligent ball in the technical scheme is characterized by comprising two balance balls and a detection ball connected between the two balance balls through a traction rope, wherein the detection ball includes a spherical inner shell, a signal processing unit arranged in the inner shell, a pluralityof ultrasonic probes evenly distributed on the inner shell, and an outer shell coating the inner shell; the signal processing unit includes an embedded PC platform and a multichannel ultrasonic card,an accelerometer, a magnetometer, a memory and a high-performance battery connected to an embedded PC platform respectively; and the embedded PC platform is also connected to an ultrasonic probe through a wire.

Description

technical field [0001] The invention relates to the field of special equipment, in particular to a pressure pipeline self-drifting type ultrasonic internal detection smart ball. Background technique [0002] The main causes of pressure pipeline accidents are corrosion, welding and material defects, equipment failure, illegal operation and external force damage. Among them, accidents caused by corrosion, welding and material defect cracking account for a large proportion. Therefore, the pressure pipelines in use should be inspected regularly at regular intervals to detect corrosion, cracks and other defects of the pressure pipelines, and eliminate accidents in the bud. [0003] Pressure pipelines mostly use techniques such as magnetic flux leakage testing, ultrasonic testing, eddy current testing, and visual testing for defect detection and safety assessment. However, these methods are only suitable for external detection of pressure pipelines. For buried pipelines deep und...

Problems solved by technology

However, these methods are only suitable for external detection of pressure pipelines. For buried pipelines deep underground, due to the limitations of their operating environment and transport media, it is difficult to detect corrosion from the outside of the pipeline. The normal working external detection method is used to detect buried pipelines, and the results are also obtained indirectly, requiring careful manual analysis and verification. At the same time, this type of method is not suitable for detecting pipelines under roads, railways, rivers, oceans and other areas , it is impossible to achieve a comprehensive inspection of the pipeline
