AI Technical Summary

Technical Problem

In existing technologies, the application of coupling agent is separated from detection and scanning, resulting in cumbersome operation, low efficiency, unstable coupling quality, and high labor intensity, especially in high temperature, high altitude, or confined working conditions.

Method used

A coupling agent application unit integrated on the outside of the detection probe was designed, including a movable sleeve, a spraying mechanism and a sealing mechanism. The pre-coating and synchronous replenishment of coupling agent are achieved through mechanical linkage, ensuring that a uniform and bubble-free coupling interface is formed between the detection probe and the pipe surface.

Benefits of technology

It simplifies the operation process, improves detection efficiency, eliminates acoustic wave scattering and attenuation caused by poor coupling, significantly improves the signal-to-noise ratio, and speeds up the single-point detection cycle.

Abstract

The present application relates to the technical field of detection equipment, and discloses a detection equipment and method for power plant pipelines, which comprises a detection equipment body, a detection host for generating and / or processing detection signals, and a detection probe for emitting and / or receiving signals to the pipeline to be detected, the detection host being electrically connected with the detection probe through a wire; and a coupling agent smearing unit arranged outside the detection probe for spraying the coupling agent on the surface of the pipeline to be detected and the detection surface of the detection probe. The present application pre-coats a uniform and bubble-free coupling agent on the detection surface of the probe through a spraying mechanism, and synchronously releases a fixed amount of the coupling agent around the probe at the moment when the probe contacts the pipeline through a mechanically linked plugging mechanism, thereby forming an ideal wet coupling interface from the probe to the pipeline with consistent thickness and no air gap, realizing the integration of the detection probe and the coupling agent smearing mechanism, and improving the operation efficiency.
