Description

Technical Field

[0001] The utility model relates to the technical field of pipeline ultrasonic detection, in particular to a pipeline ultrasonic internal detector. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting defects in parts by utilizing the characteristic that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when passing from one section to another. When the ultrasonic beam passes from the surface of the part through the probe into the metal interior, it generates reflected waves when encountering defects and the bottom surface of the part. The location and size of the defect are determined based on these waveforms. A pipe refers to a steel material with openings at both ends and a hollow section, and its length is relatively large compared to its circumference.

[0003] For example, the authorization announcement number "CN209727855U" is named as an ultrasonic detection device for pipeline detection. The screw is transmitted to the inner side of the first fixing sleeve, so that the first fixing sleeve is deformed by the support rod pressing the spring, so that the first fixing sleeve and the second fixing sleeve fix the pipeline, achieving the beneficial effect of being able to detect pipelines of different diameters and increasing practicality of use. However, the existing ultrasonic detection device for pipeline detection needs to insert the pipeline into the opened detection device when fixing the pipeline to be inspected. Then the detection device can only clamp the pipeline through the separated space and cannot be opened to accommodate the pipeline. In this way, when facing some longer pipelines for inspection, the operator needs to first insert one end of the longer pipeline into the detection device, and then slide it to a certain distance before inserting the other end to fix it. Not only is the operation process cumbersome, it also increases the workload of the staff and affects the efficiency of the use of the ultrasonic detection device for pipeline detection.

[0004] At the same time, the existing ultrasonic detection device for pipeline detection needs to insert the detection probe into the pipeline to be tested as far as possible during ultrasonic detection, so that the detection results can be more accurate. At present, the ultrasonic detection device for pipeline detection only sets the detection probe on the outside of the pipeline to be tested. In this way, the ultrasonic wave is more affected by the interference and influence of the external environment when it is emitted for detection, which may eventually lead to inaccurate detection results of the ultrasonic detection device for pipeline detection. Utility Model Content

[0005] The utility model aims to solve the problems of low efficiency and inaccurate detection results of ultrasonic detection devices used for pipeline detection, and proposes a pipeline ultrasonic internal detector.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pipeline ultrasonic internal detector is designed, including a pipeline body, a base and a support frame. The support frame is fixedly installed above the base.

The other end of the movable ring is fixedly installed with a mounting plate, and the inner side of the mounting plate is movably connected to a locking bolt, and the lower end of the locking bolt is threadedly connected to a mounting nut.

[0009] Preferably, the outer wall of the mounting plate is movably connected to one side of the top end of the fixing ring, and the side wall of the mounting nut is movably connected to the lower end of the fixing ring.

[0011] Preferably, the ultrasonic detection probe positioning and moving structure includes a horizontal plate and an electromagnet, the electromagnet is slidably connected to the outer wall of the pipe body, the horizontal plate is fixedly installed on the inner walls of two fixed rings, a sliding groove is fixedly opened inside the horizontal plate, and a slider is slidably connected to the inner side of the sliding groove, the top of the slider is fixedly connected to the lower end of the electromagnet, the outer wall of the slider is fixedly connected to a pushing block, and the bottom of the electromagnet is fixedly connected to a power cord.

[0012] Preferably, the other end of the power line is fixedly connected to an ultrasonic detection device, and the other end of the ultrasonic detection device is electrically connected to an ultrasonic detection probe through a wire.

[0013] The utility model proposes a pipeline ultrasonic internal detector, which has the beneficial effect that: the movable ring with the same size as the fixed ring on the upper side can be flipped along the rear side of the fixed ring to open or close through the flip pin. When fixing the pipeline, the movable ring is first flipped upward, and the movable ring will be opened above the fixed ring. At this time, the pipeline body can be directly placed into the open fixed ring. Thereafter, the movable ring is flipped and fastened with the fixed ring, the mounting plate falls on the end of the fixed ring, the locking bolt is inserted into the inner side of the mounting plate, and the position of the movable ring and the fixed ring can be connected by rotating the mounting nut at the lower end upward and tightening it. This can quickly and conveniently realize the installation and positioning of the detection pipeline, thereby improving the use efficiency of the pipeline ultrasonic internal detector.

[0014] When the power cord is connected, the electromagnet can generate a certain amount of suction. At this time, the ultrasonic detection probe with metal is placed inside the pipe body. At this time, the electromagnet generates suction at the lower end to adsorb the ultrasonic detection probe, and then pulls the push block horizontally to slide toward the deep part of the pipe body. In this way, the ultrasonic detection probe will be sent deeper into the pipe body through the suction provided by the electromagnet. The ultrasonic detection probe can be driven manually to a deeper position in the pipe body for ultrasonic detection, which reduces external interference, makes ultrasonic transmission less likely to be blocked, and improves the detection structure accuracy of the pipeline ultrasonic internal detector.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Example 1:

[0024] See also Figure 1-6 : In this embodiment, a pipeline ultrasonic internal detector includes a pipeline body 1, a base 2 and a support frame 4. The support frame 4 is fixedly installed above the base 2 and is vertically welded above the base 2. The tops of multiple support frames 4 support a fixed connection seat 51.

[0025] The pipeline detection rapid support structure 5 includes a connecting seat 51 and a fixing ring 52. The connecting seat 51 is fixedly installed on the top of the support frame 4. The two connecting seats 51 are welded to the outer wall of the fixing ring 52 at the left and right ends. The fixing ring 52 is fixedly connected above the two connecting seats 51. The fixing ring 52 is made of semicircular stainless steel metal. The pipeline body 1 to be inspected can be placed inside the fixing ring 52. One end of the fixing ring 52 is rotatably connected to a flip pin 57. The flip pin 57 can make the movable ring 53 above, which is similar in size to the fixing ring 52, flip along the back side of the fixing ring 52 to open or close.

[0026] The other side of the flip pin 57 is rotatably connected to the movable ring 53, and the other end of the movable ring 53 is fixedly installed with a mounting piece 54. When fixing the pipeline, first flip the movable ring 53 upwards, and the movable ring 53 will be opened above the fixed ring 52. At this time, the pipeline body 1 can be directly placed into the opened fixed ring 52, and then the movable ring 53 is flipped over to engage with the fixed ring 52, and the mounting piece 54 falls on the end of the fixed ring 52. The locking bolt 55 is inserted into the inside of the mounting piece 54, and the position of the movable ring 53 and the fixed ring 52 can be connected by rotating the mounting nut 56 at the lower end upward and tightening it. This can quickly and conveniently realize the installation and positioning of the detection pipeline.

[0027] A locking bolt 55 is movably connected to the inner side of the mounting plate 54, and a mounting nut 56 is threadedly connected to the lower end of the locking bolt 55. The outer wall of the mounting plate 54 is movably connected to the top side of the fixing ring 52, and the side wall of the mounting nut 56 is movably connected to the lower end of the fixing ring 52.

[0028] The fixing ring 52 is made of semicircular stainless steel metal. The pipe body 1 to be inspected can be placed inside the fixing ring 52. The flip pin 57 can make the movable ring 53 above, which is similar in size to the fixing ring 52, flip along the back side of the fixing ring 52 to open or close. When fixing the pipeline, first flip the movable ring 53 upwards. The movable ring 53 will be opened above the fixing ring 52. At this time, the pipe body 1 can be directly placed into the opened fixing ring 52, and then the movable ring 53 is flipped over to engage with the fixing ring 52. The mounting piece 54 falls on the end of the fixing ring 52, and the locking bolt 55 is inserted into the inside of the mounting piece 54. The position of the movable ring 53 and the fixing ring 52 can be connected by rotating the mounting nut 56 at the lower end upward and tightening it. This can quickly and conveniently realize the installation and positioning of the detection pipeline, thereby improving the use efficiency of the pipeline ultrasonic internal detector.

[0029] The ultrasonic detection probe positioning and moving structure 7 includes a transverse plate 71 and an electromagnet 74. The electromagnet 74 is slidably connected to the outer wall of the pipe body 1. The transverse plate 71 is fixedly installed on the inner walls of the two fixing rings 52. A slide groove 72 is fixedly opened inside the transverse plate 71. The inner side of the transverse plate 71 is used to support the opening of the slide groove 72. The inner side of the slide groove 72 is slidably connected with a slider 73. The slider 73 can be manually driven by a push block 75 to slide left and right along the slide groove 72. The top of the slider 73 is fixedly connected to the lower end of the electromagnet 74. The outer wall of the slider 73 is fixedly connected to the push block 75. The bottom of the electromagnet 74 is fixedly connected to a power cord 76.

[0030] When the power cord 76 is connected to supply power, the electromagnet 74 can generate a certain amount of suction. At this time, the ultrasonic detection probe 8 with metal is placed inside the pipe body 1. At this time, the electromagnet 74 generates suction at the lower end to adsorb the ultrasonic detection probe 8, and then pulls the pushing block 75 horizontally to slide toward the deep part of the pipe body 1. In this way, the ultrasonic detection probe 8 will be sent deeper into the pipe body 1 through the suction provided by the electromagnet 74. The other end of the power cord 76 is fixedly connected to the ultrasonic detection device 3. When the electromagnet 74 is powered, the ultrasonic detection probe 8 will not be powered to work.

[0031] Similarly, when the ultrasonic detection probe 8 generates ultrasonic waves, the electromagnet 74 will not be powered, thereby reducing the electromagnetic interference between the electromagnet 74 and the ultrasonic detection probe 8. The ultrasonic detection device 3 is consistent with the existing model specifications of the ultrasonic detection device for pipeline inspection with the authorization announcement number "CN209727855U" of the comparative document. When the ultrasonic detection device is started, it radiates ultrasonic waves to detect pipeline defects. The other end is electrically connected to the ultrasonic detection probe 8 through a wire.

[0032] The inner side of the horizontal plate 71 is used to support the opening of the slide groove 72, and the slider 73 can be manually driven by the pushing block 75 to slide left and right along the slide groove 72. When the power cord 76 is connected to the power supply, the electromagnet 74 can generate a certain amount of suction. At this time, the ultrasonic detection probe 8 with metal is placed inside the pipe body 1. At this time, the electromagnet 74 generates suction at the lower end to adsorb the ultrasonic detection probe 8, and then pulls the pushing block 75 horizontally to slide toward the deep direction of the pipe body 1. In this way, the ultrasonic detection probe 8 will be sent deeper into the pipe body 1 by the suction provided by the electromagnet 74. When the electromagnet 74 is powered, the ultrasonic detection probe 8 will not be powered to work. Similarly, when the ultrasonic detection probe 8 generates ultrasonic waves, the electromagnet 74 will not be powered to work. This reduces the mutual electromagnetic interference between the electromagnet 74 and the ultrasonic detection probe 8. The ultrasonic detection probe 8 can be manually driven to enter a deeper position of the pipe body 1 for ultrasonic detection, reducing external interference. The ultrasonic transmission is not easily obstructed, thereby improving the detection structure accuracy of the pipeline ultrasonic internal detector.

[0033] Working principle:

[0034] When using an ultrasonic internal detector for pipelines, the ultrasonic detection device 3 can realize the detection of internal damage defects of the pipeline by using the reflection of ultrasonic waves. The ultrasonic detection device 3 is a relatively mature existing technology, which uses ultrasonic technology to detect internal defects of pipelines and is applicable to various types of pipelines. The ultrasonic detection device 3 includes components such as a probe, a host, and a data storage card. The probe is the main part of the ultrasonic detection and is the key part for detecting the interior of the pipeline. The host is the central control part of the pipeline detector, responsible for controlling the probe and storing and analyzing data. The data storage card can store pipeline detection data for subsequent use. In this way, when the ultrasonic detection probe 8 is inserted into the pipeline to be inspected, the power supply is connected to start the ultrasonic detection device 3, and ultrasonic waves are radiated to detect internal defects of the pipeline.

[0035] Rapid pipeline placement and positioning structure of pipeline ultrasonic internal detector:

[0036] The fixing ring 52 is made of semicircular stainless steel metal. The pipe body 1 to be inspected can be placed inside the fixing ring 52. The flip pin 57 can make the movable ring 53, which is similar in size to the fixing ring 52, flip along the back side of the fixing ring 52 to open or close. When fixing the pipe, first flip the movable ring 53 upwards. The movable ring 53 will be opened above the fixing ring 52. At this time, the pipe body 1 can be directly placed into the opened fixing ring 52. Then, the movable ring 53 is flipped over to buckle with the fixing ring 52. The mounting piece 54 falls on the end of the fixing ring 52. The locking bolt 55 is inserted into the inner side of the mounting piece 54. The mounting nut 56 at the lower end is rotated upward and tightened to connect the movable ring 53 and the fixing ring 52.

[0037] The ultrasonic detection probe of the pipeline ultrasonic internal detector can move the structure:

[0038] The inner side of the horizontal plate 71 is used to support the opening of the slide groove 72, and the slider 73 can be manually driven by the pushing block 75 to slide left and right along the slide groove 72. When the power cord 76 is connected to the power supply, the electromagnet 74 can generate a certain amount of suction. At this time, the ultrasonic detection probe 8 with metal is placed in the interior of the pipe body 1. At this time, the electromagnet 74 generates suction at the lower end to adsorb the ultrasonic detection probe 8, and then pulls the pushing block 75 horizontally to slide toward the depth of the pipe body 1. In this way, the ultrasonic detection probe 8 will be sent deeper into the pipe body 1 through the suction provided by the electromagnet 74. When the electromagnet 74 is powered, the ultrasonic detection probe 8 will not be powered to work. Similarly, when the ultrasonic detection probe 8 generates ultrasonic waves, the electromagnet 74 will not be powered to work. This reduces the mutual electromagnetic interference between the electromagnet 74 and the ultrasonic detection probe 8. The ultrasonic detection probe 8 can be driven manually to enter a deeper position of the pipe body 1 for ultrasonic detection, thereby reducing external interference.

[0039] Example 2:

[0040] See also Figure 1-5: In this embodiment, a pipeline ultrasonic internal detector also includes a pipeline diameter adjustment clamping structure 6 including a torsion wheel 61 and a clamping arc plate 63. The two clamping arc plates 63 are movably connected to the outer wall of the pipeline body 1 on both sides. There are two clamping arc plates 63, one is set inside the fixed ring 52, and the other is set inside the movable ring 53. When the movable ring 53 and the fixed ring 52 are tightly clamped, in order to more firmly clamp the inner pipe bodies 1 with different diameters, the torsion wheels 61 on both sides can be twisted, and the torsion wheels 61 will push the screw 62 By rotating, the screw 62 can push the clamping arc plate 63 at the top end to tighten and push it inward, so that the pipe body 1 can be further clamped and fixed. The inner walls of the two clamping arc plates 63 are fixedly installed with a clamping layer 64. The clamping layer 64 adopts a vertical metal steel texture. The clamping layer 64 can increase the friction force of the clamping arc plate 63. The outer sides of the two clamping arc plates 63 are movably connected with two screws 62. The other ends of the two screws 62 are fixedly installed with a torsion wheel 61. The two screws 62 are respectively threadedly connected to the inner ends of the fixed ring 52 and the movable ring 53.

[0041] Working principle:

[0042] There are two clamping arc plates 63, one is arranged inside the fixed ring 52, and the other is arranged inside the movable ring 53. When the movable ring 53 and the fixed ring 52 are fitted and tightened, in order to be able to clamp and fix the inner pipe body 1 of different diameters more firmly, the torsion wheels 61 on both sides can be screwed. The torsion wheel 61 will push the screw 62 to rotate, and the screw 62 can push the clamping arc plate 63 at the top end to tighten and push it inward, so that the pipe body 1 can be further clamped and fixed. The inner walls of the two clamping arc plates 63 are fixedly installed with a clamping layer 64. The clamping layer 64 adopts a vertical metal steel texture, and the clamping layer 64 can increase the friction of the clamping arc plate 63.
