The invention discloses an array ultrasonic internal detection structure for a pipeline. The structure comprises two ultrasonic split bodies arranged oppositely, wherein the two ultrasonic split bodies are connected through an adjustable connecting joint; the two ultrasonic split bodies are provided with driving connecting components, and under the condition that the ultrasonic split bodies are connected to driving parts, the structure can move in a pipeline to be detected in order to conduct ultrasonic detection on the pipeline to be detected; the ultrasonic split bodies comprise probe mounting cylinders, wherein supporting components are arranged at the two ends of each probe mounting cylinder, the two probe mounting cylinders are each provided with a plurality of probe components in the circumferential direction, and the corresponding probe components between the two probe mounting cylinders are arranged in a staggered mode, so that the probe components can fully cover the pipeline to be detected in the ultrasonic detection process of the structure. According to the structure, 360-degree full-coverage ultrasonic detection of the pipeline is realized, ultrasonic detection of a bent pipeline is also realized, and the efficiency and precision of ultrasonic detection of the pipeline are improved to a certain extent.
Description
technical field [0001] The invention belongs to the technical field of pipeline corrosion non-destructive detection, and in particular relates to a pipeline array ultrasonic internal detection structure. Background technique [0002] As an economical, efficient and safe means of material transportation, pipelines are widely used in many important industrial fields, such as shipping, petrochemical, nuclear energy, electric power, etc. With the increase of service time, the pipeline will be corroded by the action of internal and external media. In severe cases, it will cause pipeline leakage and even major safety accidents, which will bring huge hidden dangers to the safe operation of equipment. [0003] The traditional ultrasonic detection of pipeline corrosion uses a single probe to perform local single-point detection on the outside of the pipeline. The detection range is small, the overall corrosion situation of the pipeline cannot be obtained, and the detection capability...
