Phased array probe detection device for internal pipeline welded joint detection

The utility model provides a phased array probe detection device for internal pipeline welded joint detection. The device comprises a support frame, a telescopic rod and a probe, and is characterized in that the support frame consists of a supporting rod and a tripod; the supporting rod is perpendicular to the middle axis of the tripod; and the front end of the supporting rod is connected with the telescopic rod with the probe. According to the device, the problems that the pipeline weld joint only can be detected by virtue of the outer wall by virtue of conventional phased array detection equipment, some pipelines blocked or covered by buildings and welding members cannot be effectively detected or detection cannot be implemented because the pipeline cannot be touched by arms due to extremely long pipeline distance when the interior of the pipeline is detected are solved.
