Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a sound wave detector for detecting breakage, corrosion and leakage of oil and gas pipelines. Background Art

[0002] When breakage, corrosion and leakage occur in oil and gas pipelines, it is necessary to find out the problem points in time for repair. Generally, a sound wave detector is used to detect the pipelines. The staff fits the detection head part of the sound wave detector on the pipeline surface for detection. The detection head transmits the detected information to the detector, and then the staff understands the detection result through the screen display on the detector.

[0003] Some existing sound wave detectors are composed of a detector body and a detection head. The user holds the detection head and fits it on the surface of the oil and gas pipeline to detect the oil and gas pipeline through the detection head. However, when in a complex environment where the oil and gas pipelines are densely distributed, when the user detects one of the pipelines, due to the inconvenient movement of the body and the difficulty of passing the hand through the gap, it is difficult to detect the back of the oil and gas pipeline. Generally, it is necessary to disassemble the oil and gas pipeline for detection. However, the oil and gas pipeline is installed and fixed by multiple bolts, and the disassembly is relatively troublesome. If the disassembled oil and gas pipeline has problems such as breakage, corrosion and leakage, the disassembly work is useful work and the worker can directly repair it. But if the disassembled oil and gas pipeline is intact, the disassembly work is useless work and will affect the efficiency of the detection work. Content of the Utility Model

The detector body is connected with a connecting frame through a connecting wire. One end of the connecting frame is rotatably connected with a rotating rod. One end of the rotating rod is connected with a first conical meshing wheel. The surface of the connecting frame is rotatably connected with a lead screw. The upper end of the lead screw is connected with a second conical meshing wheel. The first conical meshing wheel and the second conical meshing wheel are meshed with each other. The surface of the lead screw is threadedly connected with a lifting block. The surface of the lifting block is connected with a connecting plate. The connecting plate is slidably connected with an H-shaped rod passing through it. The lower end of the connecting frame is connected with an arc-shaped plate. An arc-shaped groove is opened on the surface of the arc-shaped plate. An arc-shaped limiting block is slidably connected inside the arc-shaped groove.

Detailed implementation manners

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0018] Please refer toFigures 1-4 , the present utility model provides a technical solution: an acoustic wave detection instrument for pipeline breakage, corrosion and leakage of oil and gas pipelines, including a detector body 1. The detector body 1 is connected with an adjusting mechanism 2 through a connecting wire. The adjusting mechanism 2 includes a connecting frame 21. The detector body 1 is connected with the connecting frame 21 through a connecting wire. One end of the connecting frame 21 is rotatably connected with a rotating rod 22. One end of the rotating rod 22 is connected with a first conical meshing wheel 23. The surface of the connecting frame 21 is rotatably connected with a lead screw 24. The upper end of the lead screw 24 is connected with a second conical meshing wheel 25. The first conical meshing wheel 23 and the second conical meshing wheel 25 are meshed with each other. The surface of the lead screw 24 is threadedly connected with a lifting block 26. The surface of the lifting block 26 is connected with a connecting plate 27. The connecting plate 27 is slidably connected with an H-shaped rod 28 passing through it. The lower end of the connecting frame 21 is connected with an arc plate 29. The surface of the arc plate 29 is provided with an arc groove 291. An arc limiting block 292 is slidably connected inside the arc groove 291. One end of the arc limiting block 292 is provided with a detection head 293. The other end of the arc limiting block 292 is hinged with the H-shaped rod 28.

[0019] In this implementation scheme, first, the adjusting mechanism 2 is passed through the gap between two pipelines in a horizontal state, and then the adjusting mechanism 2 is rotated 90 degrees to align the arc plate 29 with the pipeline, so that the detection head 293 fits the surface of the pipeline, thereby using the detection head 293 to detect the pipeline. Then, the rotating rod 22 is rotated, which drives the first conical meshing wheel 23 to rotate, and further drives the second conical meshing wheel 25 to rotate, and then the lead screw 24 rotates. Since the lead screw 24 rotates, the lifting block 26 is driven to lift, and then the connecting plate 27 is driven to lift. Since the connecting plate 27 lifts, the arc limiting block 292 is driven along the arc groove 291 by the H-shaped rod 28, and at the same time, the H-shaped rod 28 slides relative to the connecting plate 27. Therefore, the detection head 293 moves in an arc on the surface of the pipeline and keeps the tangent of the detection head 293 perpendicular to the pipeline, so that transposition detection can be carried out. Therefore, by setting the adjusting mechanism 2, it is convenient for the user to detect the back of the pipeline in an environment with a small working space, so that the pipeline does not need to be disassembled for detection, and the working efficiency of the detection work is improved.

[0020] Specifically, a limit screw 294 is threadedly connected to the surface of the connecting frame 21, and the limit screw 294 is correspondingly arranged at the rotation engagement position of the rotating rod 22.

[0021] In this embodiment, when the position of the detection head 293 is adjusted, by finely adjusting the limit screw 294, the upper end of the limit screw 294 abuts against the rotating rod 22. Since the rotating rod 22 is fixed, the position of the detection head 293 is locked, thereby preventing the problem that the position of the detection head 293 is unstable due to the lack of self-locking effect of the rotating rod 22.

[0022] Specifically, two fixing rings 295 are connected to the surface of the H-shaped rod 28, and two springs 296 are wound around the surface of the H-shaped rod 28. One end of the spring 296 is connected to the fixing ring 295, and the other end of the spring 296 is connected to the connecting plate 27.

[0023] In this embodiment, when the H-shaped rod 28 slides relative to the connecting plate 27, the spring 296 is stretched or compressed. Through the elastic force of the spring 296, the sliding of the H-shaped rod 28 becomes more stable, so that when this mechanism is adjusted, the arc-shaped limiting block 292 moves more stably.

[0024] Specifically, angle lines 297 are provided on the surface of the arc-shaped plate 29, and an indicating plate 298 is connected to the surface of the arc-shaped limiting block 292. The indicating plate 298 is arranged corresponding to the detection head 293.

[0025] In this embodiment, when the detection head 293 detects a problem point of the pipeline, since the indicating plate 298 is aligned with the detection head 293, when the user takes out this mechanism, by observing the degree of the angle line 297 corresponding to the indicating plate 298, the position of the problem point of the pipeline can be known.

[0026] Specifically, two connecting blocks 299 are connected to the surface of the arc-shaped plate 29, and one end of the connecting block 299 is connected to a pressing plate 2991.

[0027] In this embodiment, the pressing plate 2991 can be pressed against the surface of the pipeline, so as to give the user a stable supporting force, and thus it is convenient for the user to hold this mechanism.

[0028] Specifically, the pressing plate 2991 is arc-shaped, and an anti-slip pad is provided at one end thereof.

[0029] In this embodiment, the pressing plate 2991 is arc-shaped, which can better fit the surface of the pipeline. At the same time, the anti-slip pad can increase the friction between the pressing plate 2991 and the pipeline, so that this mechanism fits more stably. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
