Description

Technical Field

[0001] The utility model relates to the technical field of pipeline defect detection, and particularly relates to an ultrasonic non-destructive detection device for pipeline defects. Background Technique

[0002] The ultrasonic non-destructive detection device for pipeline defects is a device that uses ultrasonic technology to detect internal defects of pipelines. It can quickly and accurately detect defects such as cracks and inclusions inside the pipeline without damaging the pipeline structure. The working principle of the ultrasonic non-destructive detection device for pipeline defects is based on the propagation and reflection characteristics of ultrasonic waves in a medium. When the ultrasonic wave signal propagates inside the pipeline and encounters defects (such as cracks and inclusions), reflection or scattering will occur. After these reflected or scattered ultrasonic wave signals are received by the receiver and processed and analyzed by the signal processing system, information related to the defects, such as the location, size, and shape of the defects, can be extracted. When in use, various types of probes are used in the ultrasonic non-destructive detection device and need to be carried separately, which increases the burden on the user and is not easy to use, having certain deficiencies. Therefore, we have proposed an ultrasonic non-destructive detection device for pipeline defects. Content of the Utility Model

[0004] Therefore, the technical solution adopted by the utility model is as follows: an ultrasonic non-destructive detection device for pipeline defects, including an ultrasonic flaw detector, a mounting plate, a winding rack, a connecting rope, a sealing cover, and a limiting block. A threaded groove and a storage groove are opened at the top end of the ultrasonic flaw detector. A limiting groove is opened inside the storage groove. The mounting plate is slidably connected to the ultrasonic flaw detector through the limiting groove. A plurality of jacks are opened on the mounting plate. The winding rack is arranged on the mounting plate, and the mounting block provided at the bottom of the winding rack is inserted into the jacks. One end of the connecting rope is arranged at the top end of the mounting plate. The sealing cover is hinged to the ultrasonic flaw detector. The left side of the sealing cover is fixedly connected to the other end of the connecting rope. A fastening rod is threadedly connected to the sealing cover. The limiting block is arranged inside the storage groove.

[0005] Preferably, a wire is arranged on the left side of the ultrasonic flaw detector, and a probe is arranged on the wire. A handle is rotatably connected to the outside of the ultrasonic flaw detector.

[0026] Specifically, a threaded groove 104 and a storage groove 105 are opened at the top of the ultrasonic flaw detector 100. A limiting groove 107 is opened inside the storage groove 105. A lead wire 101 is arranged on the left side of the ultrasonic flaw detector 100, and a probe 102 is arranged on the lead wire 101. A handle 103 is rotatably connected to the outside of the ultrasonic flaw detector 100. Blocks 106 are arranged at the corners inside the storage groove 105. The cross-section of the storage groove 105 is rectangular. When in use, the lead wire 101 and the probe 102 can be placed in the storage groove 105 for storage and carrying. The probe 102 can contact the pipeline, and after contact, it can detect the defects of the pipeline for use.

[0027] Specifically, the mounting plate 200 is slidably connected to the ultrasonic flaw detector 100 through the limiting groove 107. A plurality of jacks 201 are opened on the mounting plate 200. When in use, the limiting groove 107 plays a limiting role, so that the mounting plate 200 can only move along the limiting groove 107, facilitating the connecting rope 400 to drive the mounting plate 200 to move.

[0028] Specifically, the winding rack 300 is arranged on the mounting plate 200, and the mounting block 301 arranged at the bottom of the winding rack 300 is inserted into the jack 201.
