DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4As shown, a detection device with auxiliary structure for magnetic leakage in pipelines described in an embodiment of the utility model comprises a magnetic leakage internal detector 1; a pair of slide rails 11 are fixedly connected to the side wall of the magnetic leakage internal detector 1; the pair of slide rails 11 are symmetrically arranged on both sides of the magnetic leakage internal detector 1 and have the same structure; a slider 12 is slidably connected to the inner wall of the slide rail 11; a plurality of rubber strips 13 are evenly fixed to the side wall of the slider 12; a telescopic rod 14 is fixed to the side wall of the slider 12; a first spring 15 is sleeved on the outer side of the telescopic rod 14; the ends of the telescopic rod 14 and the first spring 15 are fixedly connected to the same scraper 16; when in use, the staff first holds the scraper 16, aligns the slide rail 11 with the slider 12, and inserts the slider 12 onto the inner wall of the slide rail 11. At this time, a certain friction force will be generated due to the contact between the rubber strip 13 and the slide rail 11. , so that the scraper 16 can be fixed, and then when the magnetic flux leakage detector 1 is placed in the pipeline, the scraper 16 is squeezed to cause the telescopic rod 14 and the first spring 15 to perform telescopic movement, and under the elastic action of the first spring 15, a certain reaction force can be applied to the scraper 16, so that the scraper 16 can fully contact the inner wall of the pipeline. At this time, the scraper 16 can scrape off the dirt and impurities adhering to the inner wall of the pipeline. In this process, the dirt and impurities adhering to the inner wall of the pipeline can be reduced, resulting in obstruction between the magnetic flux leakage detector 1 and the pipeline, thereby affecting the accuracy of the magnetic flux leakage detector 1 in detecting the pipeline. At this time, the scraper 16 is set to clean the dirt and impurities adhering to the pipeline, thereby improving the accuracy of the magnetic flux leakage detector 1 during detection. At the same time, the slide rail 11 can facilitate the disassembly and maintenance of the scraper 16.

[0024] like Figure 1-4 As shown, a pair of first elastic rods 2 are fixedly connected to the side wall of the scraper 16; the pair of first elastic rods 2 are symmetrically arranged on both sides of the scraper 16 and have the same structure; a weight ball 21 is fixedly connected to the end of the first elastic rod 2; a plurality of elastic sheets 22 are evenly fixedly connected to the side wall of the scraper 16; the positions of the weight ball 21 and the elastic sheet 22 correspond to each other; when in use, a certain vibration is generated when the leakage magnetic internal detector 1 moves in the pipeline, causing the first elastic rod 2 to swing, and at the same time, under the action of the gravity of the weight ball 21, the swing range of the first elastic rod 2 can be increased, and at this time, during the swinging process of the first elastic rod 2, The counterweight ball 21 hits the wall of the elastic sheet 22, and the elastic sheet 22 can be caused to shake to a certain extent by hitting it. During the shaking process of the elastic sheet 22, a certain vibration will be generated, and at this time, the vibration will be transmitted to the wall of the scraper 16, so that the dirt and impurities adhering to the wall of the scraper 16 can be vibrated off. In this process, the scraper 16 can be reduced. When used for a long time, there will be a lot of dirt and impurities adhering to the side wall, which is inconvenient to clean, thereby affecting the use effect of the scraper 16. At this time, the elastic sheet 22 is set to clean the dirt and impurities adhering to the side wall of the scraper 16.

[0025] like Figure 1-4 As shown, the side wall of the slider 12 is fixedly connected to the support plate 3; the side wall of the support plate 3 is fixedly connected to the second spring 31; the end of the second spring 31 is fixedly connected to the insertion rod 32; the side wall of the insertion rod 32 is fixedly connected to the pull rod 33; the pull rod 33 passes through the wall of the support plate 3 and is slidably connected thereto; the side wall of the slide rail 11 is provided with a slot 34; when in use, first hold the pull rod 33 and pull it, and the insertion rod 32 can be moved by pulling the pull rod 33, at this time the second spring 31 is squeezed and will perform telescopic movement, when the slider 12 is fully inserted into the slide rail When the slider 12 is fixed on the inner wall of the slide rail 11, the rod 32 will correspond to the position of the slot 34. At this time, the pull rod 33 is released, and the second spring 31 will exert a certain reaction force on the rod 32 to push the rod 32 onto the side wall of the slot 34, thereby fixing the slider 12. In this process, the poor fixing effect of the slider 12 on the inner wall of the slide rail 11 can be reduced, resulting in the slider 12 easily sliding out from the inner wall of the slide rail 11 when the slider 12 is accidentally pulled. At this time, the rod 32 is set to further increase the fixing effect of the scraper 16.

[0026] like Figure 1-4 As shown, a pair of elastic plates 4 are fixedly connected to the side walls of the slide rail 11; the pair of elastic plates 4 are symmetrically arranged on both sides of the slide rail 11 and have the same structure; a second elastic rod 41 is fixedly connected between the elastic plate 4 and the slide rail 11; when in use, by inserting the slider 12 onto the inner wall of the slide rail 11, the slider 12 will contact and squeeze the elastic plates 4 on both sides, and by squeezing the elastic plates 4, a certain deformation can be generated between the slider 12 and the second elastic rod 41, at this time, the slider 12 will slide toward the middle of the elastic plates 4 on both sides, and at the same time, under the elastic action of the elastic plates 4, a certain reverse thrust can be applied to the slider 12, so that the slider 12 is moved to The middle part of the slide rail 11 is pushed, and under the elastic action of the second elastic rod 41, the slider 12 and the elastic plate 4 can be offset, and a certain reverse thrust can be applied to the elastic plate 4, so that the elastic plate 4 can be quickly reset. In this process, the difficulty in aligning the slider 12 and inserting the slider 12 into the inner wall of the slide rail 11 can be reduced. At this time, the elastic plate 4 is set to limit the slider 12 when it is inserted into the inner wall of the slide rail 11. At the same time, the second elastic rod 41 can support the elastic plate 4, reducing the deformation of the elastic plate 4 and the difficulty in resetting.

[0027] like Figure 1-4As shown, the side wall of the scraper 16 is evenly fixed with multiple cleaning brushes 5; the side wall of the cleaning brush 5 is fixed with a connecting rod 51; the connecting rod 51 passes through the wall of the cleaning brush 5 and is fixed thereto; when in use, when the scraper 16 scrapes off the dirt and impurities in the pipeline, the cleaning brush 5 can be used to clean the position after the scraper 16 scrapes off the remaining dirt and impurities, and at the same time, the multiple cleaning brushes 5 can be fixedly connected by the connecting rod 51 so that they are concentrated together during cleaning. In this process, the poor cleaning effect of the scraper 16 can be reduced, resulting in dirt and impurities still adhering to the inner wall of the pipeline, thereby causing a certain impact on the detection effect of the leakage magnetic internal detector 1. At this time, the cleaning brush 5 is set to further increase the cleaning effect of the leakage magnetic internal detector 1, and at the same time, the connecting rod 51 can increase the concentration of the cleaning brush 5 during cleaning, thereby improving the cleaning effect.

[0028] like Figure 1-4 As shown, the side wall of the counterweight ball 21 is fixedly connected with a rubber sleeve 6; when in use, when the counterweight ball 21 collides with the elastic sheet 22, the flexible action of the rubber sleeve 6 can prevent the direct contact between the counterweight ball 21 and the elastic sheet 22. In this process, the impact of the counterweight ball 21 on the elastic sheet 22 can be reduced. Over time, the elastic sheet 22 is easily damaged. At this time, the rubber sleeve 6 is set to protect the counterweight ball 21 from colliding with the elastic sheet 22, thereby reducing the damage caused by the counterweight ball 21 to the elastic sheet 22.

[0029] like Figure 1-4 As shown, the side wall of the pull rod 33 is evenly fixed with a plurality of rubber blocks 7; when in use, when the pull rod 33 is gripped and pulled, the hand will contact the rubber block 7 and generate a certain friction force. In this process, the friction force between the hand and the pull rod 33 can be reduced, resulting in the hand easily slipping off the side wall of the pull rod 33 when the pull rod 33 is pulled. At this time, the rubber block 7 is provided to increase the firmness of the hand on the side wall of the pull rod 33.

[0030] like Figure 1-4 As shown, a plurality of sponge pads 8 are evenly fixed to the side wall of the elastic plate 4; when in use, when the elastic plate 4 limits the slider 12, the sponge pad 8 can block the direct contact between the elastic plate 4 and the slider 12. In this process, a certain friction can be generated when the slider 12 contacts the elastic plate 4, resulting in a certain wear on the elastic plate 4, thereby affecting the service life of the elastic plate 4. At this time, the sponge pad 8 is provided to protect the elastic plate 4 and improve the service life of the elastic plate 4.

[0031] When working, firstly, the staff holds the scraper 16, aligns the slide rail 11 with the slider 12, and inserts the slider 12 into the inner wall of the slide rail 11. At this time, a certain friction force is generated by the contact between the rubber strip 13 and the slide rail 11, so that the scraper 16 can be fixed. After that, when the magnetic flux leakage detector 1 is placed in the pipeline, the scraper 16 is squeezed to make the telescopic rod 14 and the first spring 15 telescopic movement, and under the elastic action of the first spring 15, a certain reaction force can be applied to the scraper 16, so that the scraper 16 can fully contact the inner wall of the pipeline. At this time, the scraper 16 can scrape off the dirt and impurities adhering to the inner wall of the pipeline. When in use, the magnetic flux leakage detector 1 will generate when it moves in the pipeline. A certain vibration causes the first elastic rod 2 to swing. At the same time, under the gravity of the counterweight ball 21, the swing range of the first elastic rod 2 can be increased. At this time, during the swinging of the first elastic rod 2, the counterweight ball 21 will hit the wall of the elastic sheet 22. By hitting the elastic sheet 22, it can cause a certain shake. During the shaking of the elastic sheet 22, a certain vibration will be generated. At this time, the vibration will be transmitted to the wall of the scraper 16, so that the dirt and impurities adhering to the wall of the scraper 16 can be shaken off. When in use, first hold the pull rod 33 and pull it. By pulling the pull rod 33, the insertion rod 32 can be moved. At this time, the second spring 31 is squeezed and telescopic. When the slider 12 is fully inserted into the slide rail 1 1, the insertion rod 32 will correspond to the position of the slot 34. At this time, the pull rod 33 is released, and the second spring 31 will apply a certain reaction force to the insertion rod 32, pushing the insertion rod 32 to the side wall of the slot 34, so that the slider 12 can be fixed. When in use, during the process of inserting the slider 12 into the inner wall of the slide rail 11, the slider 12 will contact and squeeze the elastic plates 4 on both sides. By squeezing the elastic plates 4, a certain deformation can be generated between the slider 12 and the second elastic rod 41. At this time, the slider 12 will slide toward the middle of the elastic plates 4 on both sides. At the same time, under the elastic action of the elastic plates 4, a certain counter-thrust force can be applied to the slider 12 to push the slider 12 to the middle of the slide rail 11, and the slider 12 can be pushed to the middle of the slide rail 11 by the second elastic rod 41. 1, after the slider 12 and the elastic plate 4 are offset, a certain reverse thrust is applied to the elastic plate 4, so that the elastic plate 4 can be quickly reset. When in use, when the scraper 16 scrapes off the dirt and impurities in the pipeline, the cleaning brush 5 can clean the position after the scraper 16 scrapes off the remaining dirt and impurities. At the same time, multiple cleaning brushes 5 can be fixedly connected by the connecting rod 51 so that they are concentrated together when cleaning. When in use, when the counterweight ball 21 hits the elastic sheet 22, the flexible action of the rubber sleeve 6 can prevent the counterweight ball 21 from directly contacting the elastic sheet 22. When in use, when the pull rod 33 is held and pulled, the hand will contact the rubber block 7 and generate a certain friction force.
