Flexible probe ring for pipeline guided wave detection system

Abstract

The invention provides a flexible probe ring for a pipeline guided wave detection system. A plurality of probe module seats (7) and probe module press sheets (8) are installed on the inner side of a steel ring (9) with a circular opening along the axial direction, a probe module interface (6) is arranged at one end of the side of each probe module seat (7), and an air wrapping belt (11) with a circular opening is wrapped outside the steel ring (9), an air bag (12) is arranged in the air bag wrapping belt (11), and an outer cover layer (10) with a circular opening is further wrapped outside the air bag wrapping belt (11). The outside of the outer cover layer (10) is fixedly connected with a lemoTM interface seat (2) and an inflation opening (4). Each ends of the openings of the steel ring (9), the air bag wrapping belt (11) and the outer cover layer (10) are connected with one end of a butt joint clamp (5). A probe module (1) is connected with the lemoTM interface seat (2) on a probe ring (1) through a cable and then is connected with a system host. The flexible probe ring for the pipeline guided wave detection system is good in mechanical coupling effect, light and convenient to transport, not easy toe abrade and damage.

Description

technical field [0001] The invention relates to a flexible probe ring of a pipeline guided wave detection system. The field of measurement and piping technology involving ultrasound. Background technique [0002] Guided wave detection system can be used for the detection of pipeline defects. However, the sensors in the guided wave detection system need to be coupled. In the pipeline guided wave detection system, since the frequency of use of the guided wave is low, no couplant is required for coupling, but only mechanical coupling is required. However, the quality of the mechanical coupling has a great influence on the test results. [0003] At present, the research institutes and universities engaged in the research of ultrasonic guided wave technology in the world mainly include British Imperial College of Technology, the Southwest Research Institute of the United States, and the University of Pennsylvania in the United States. The British guided wave company (GUL) is e...

Problems solved by technology

But the design of the docking fixture is not flexible enough, the airbag and the inflation port are easily damaged, the material is easy to wear, and the base material is a steel ring. It is easier to install the curved arm to the mouth before installing the probe, but it is difficult to align the slot after installing the probe.

The existing equipment uses MCX wiring, which is convenient to use, but it is easy to block the plug due to dust entering during field use, and repeatedly plugging and unplugging the wiring head when installing and removing the probe will easily cause the wire core to be stressed and distorted
