[0002] In chemical production and related operations, pipelines are typically used to transport materials to designated areas for chemical production.

[0003] Most chemical materials are corrosive. Pipes are usually made of metal, which can resist corrosion to some extent. However, they will still corrode after long-term use. Therefore, it is necessary to use ultrasonic methods to detect corrosion on the pipe walls.

[0004] Currently, when detecting corrosion on pipe walls, cylinders are used to adjust the inner clamping plates according to the pipe diameter. Multiple sets of cylinders are used to ensure stable clamping. However, during adjustment, all cylinders need to be started and adjusted synchronously, making the adjustment to fit the pipe diameter cumbersome. Furthermore, if one set of cylinders fails to adjust properly, the clamping effect on the pipe will decrease, making it impossible to effectively and stably detect corrosion on the pipe wall. Therefore, this invention provides a corrosion damage early warning device for chemical pipelines to solve the above-mentioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6In this embodiment of the utility model, a chemical pipeline corrosion damage early warning device includes a main component, an adjustment component, and a locking component. The main component includes an outer ring plate 1, a base plate 2, an adjustment motor 3, an adjustment gear 4, a clamping component, and a driving component. There are two sets of outer ring plates 1, with one end of each set movably connected to the other. The two sets of outer ring plates 1 can rotate about the connecting end as the axis. When closed, the two sets of outer ring plates 1 form a ring shape. The base plate 2 is installed on one side of the outer ring plate 1. The adjustment motor 3 is installed on the base plate 2. The adjustment motor 3 is a disclosed technology and will not be described in detail here. The adjustment gear 4 is installed at the output end of the adjustment motor 3. The end of the adjustment gear 4 away from the adjustment motor 3 slides through the corresponding side wall of the outer ring plate 1. The clamping component is arranged around the outer ring plate 1, with one end of the clamping component extending to the inner ring of the outer ring plate 1. The driving component is movably installed on the base plate 2. The driving component can drive the main component to move on the pipeline.

[0026] The adjustment component is installed on the inner side of the outer ring plate 1 corresponding to the position of the adjustment gear 4. The adjustment component is also movably connected to the clamping component. The adjustment motor 3 starts and controls the adjustment gear 4 to rotate, so that the adjustment gear 4 can drive the adjustment component to move and adjust the clamping component, so that different sizes of pipe diameters can be clamped and adjusted.

[0027] The locking assembly is installed on the two sets of outer ring plates 1 at a position away from the mutually movable connection end. The locking assembly enables the two sets of outer ring plates 1 to complete the sealing and locking.

[0028] The clamping component includes a push rod 9, a clamping plate 11, and a detection head 12. The push rod 9 is mounted around the side wall of the outer ring plate 1. One end of the push rod 9 slides through the corresponding position of the wall of the outer ring plate 1 and extends to the inner ring position of the outer ring plate 1. The clamping plate 11 is fixedly mounted on the push rod 9 at one end of the inner ring of the outer ring plate 1. The detection head 12 is mounted on the end of the clamping plate 11 away from the clamping plate 11. The push rod 9 and the adjustment component are movably connected to each other. By adjusting the adjustment component, the push rod 9 can be moved and adjusted on the side wall of the outer ring plate 1, thereby adjusting the distance between the clamping plate 11 connected to the push rod 9 and the axis of the inner ring of the outer ring plate 1, so as to effectively adapt to the pipe diameter.

[0029] The detection head 12 includes an integrated ultrasonic sensor that can transmit / receive ultrasonic signals behind the pipe wall and determine the degree of corrosion by analyzing the acoustic feedback.

[0030] The driving component includes a movable plate 5, a drive wheel 6, a drive motor 7, and a fixed base block 32. The fixed base block 32 is fixedly installed on the bottom wall of the base plate 2. The movable plate 5 is movably installed on the fixed base block 32 and can be rotated and adjusted on the fixed base block 32. The drive wheel 6 is movably installed at one end of the movable plate 5 away from the fixed base block 32. The drive motor 7 is installed on the side wall of the movable plate 5. The output end of the drive motor 7 passes through the corresponding position of the wall of the movable plate 5 and is connected to the drive wheel 6. When the drive motor 7 is started, it can drive the drive wheel 6 to rotate, thereby enabling the main component to move on the pipe. Because the movable plate 5 can rotate on the fixed base block 32, when the pipe diameter changes, the movable plate 5 can be driven by gravity to make the drive wheel 6 fit the pipe wall, thereby enabling the driving component to move the main component on pipe walls of various specifications.

[0031] The driving component also includes a driven wheel 13, which is movably mounted on the clamping plate 11 at one end away from the push rod 9. The driven wheel 13 can rotate on the clamping plate 11. When the drive motor 7 controls the drive wheel 6 to move the main component on the pipe wall, the driven wheel 13 can assist in pushing the clamping plate 11 to move on the pipe wall, thereby reducing the movement resistance of the main component on the pipe wall.

[0032] The adjustment assembly includes a driving component and a driven component. The driving component is movably installed inside the outer ring plate 1 and meshes with the adjusting gear 4. The driven component is movably installed on the outer ring plate 1 at the position corresponding to the push rod 9. One end of the driven component is movably connected to the push rod 9, and the other end of the driven component is connected to the driving component. The rotation of the adjusting gear 4 drives the driving component to adjust on the outer ring plate 1, so that the driving component can drive the driven component to adjust the push rod 9 accordingly. This allows the push rod 9 to adjust the clamping plate 11 in the inner ring area of ​​the outer ring plate 1 accordingly, thereby completing the clamping according to the pipe diameter.

[0033] The driving component includes an adjusting ring 15, adjusting teeth 17, and adjusting groove 20. The adjusting groove 20 is formed on the side wall of the outer ring plate 1 near the base plate 2, and the adjusting groove 20 on the top set of outer ring plates 1 and the adjusting gear 4 are positioned corresponding to each other. The adjusting gear 4 passes through the corresponding wall of the outer ring plate 1 and extends into the adjusting groove 20. The adjusting ring 15 is annular plate-shaped, and the size of the adjusting ring 15 is adapted to the size of the inner side of the adjusting groove 20. The adjusting ring 15 is movably installed in the adjusting groove 20. The adjusting teeth 17 are annularly spaced on the outer side wall of the top set of adjusting rings 15, and the position of the adjusting teeth 17 corresponds to the position of the adjusting gear 4. The adjusting teeth 17 on the top set of adjusting rings 15 and the adjusting gear 4 mesh with each other. The driven component is installed on the side wall of the adjusting ring 15 away from the base plate 2.

[0034] The driven component includes an auxiliary adjustment groove 8, an auxiliary adjustment rod 10, an adjustment plate 16, and a movable groove 21. The movable groove 21 is located on the inner side of the outer ring plate 1, corresponding to the clockwise side of the push rod 9. The movable groove 21 and the adjustment groove 20 are interconnected. The adjustment plate 16 is located in the movable groove 21 and is fixedly connected to the adjustment ring 15. The adjustment plate 16 can move on the movable groove 21. The auxiliary adjustment rod 10 is located between the push rod 9 and the adjustment plate 16. One end of the auxiliary adjustment rod 10 is movably mounted on the side wall of the push rod 9, and the other end of the auxiliary adjustment rod 10 is movably mounted on the outer side of the adjustment plate 16 near the push rod 9. Both ends of the auxiliary adjustment rod 10 can be rotated and adjusted on the push rod 9 and the adjustment plate 16. The auxiliary adjustment groove 8 is located on the outer side wall of the outer ring plate 1, corresponding to the position of the movable groove 21. The auxiliary adjustment groove 8 facilitates the adjustment of the auxiliary adjustment rod 10 under the movement of the adjustment plate 16.

[0035] When the adjusting gear 4 rotates, the adjusting teeth 17 on the top set of adjusting rings 15 can drive the adjusting rings 15 to rotate accordingly, thereby driving the adjusting plate 16 to move inside the movable groove 21. Due to the fixed length limitation of the auxiliary adjusting rod 10, when the adjusting plate 16 moves inside the movable groove 21, it can drive the push rod 9 to perform a matching extension and retraction adjustment on the outer ring plate 1, thereby controlling multiple sets of clamping plates 11 to complete the clamping adjustment according to the pipe diameter.

[0036] Two sets of adjusting rings 15 are connected by connectors at the movable connection ends of the two sets of outer ring plates 1. The two sets of adjusting rings 15 are connected by the connectors. When the top set of adjusting rings 15 is adjusted, it can stably push the bottom set of adjusting rings 15 to adapt and adjust, thereby enabling synchronous adjustment of multiple sets of clamping plates 11.

[0037] The locking assembly includes a locking plate 14, a plug, a clip, and a lock. The locking plate 14 is fixedly installed on the side wall of the two sets of outer ring plates 1 at a position away from the movable connection end of the two sets of outer ring plates 1. The plug is installed on the two sets of locking plates 14. The clip is installed on the top set of locking plates 14. The plug can be inserted into the clip to lock the plug. The lock is installed on the bottom set of locking plates 14. The clip can lock the clip.

[0038] The insert includes a slot 22, a locking rod 23, a through groove 24, and a slot 25. The slot 22 is located above the top set of locking plates 14 and penetrates the side wall of the locking plate 14 away from the outer ring plate 1. The locking rod 23 is obliquely and fixedly installed above the bottom set of locking plates 14, and the locking rod 23 is obliquely inclined towards the side away from the outer ring plate 1. The through groove 24 is located on the bottom wall of the top set of locking plates 14 and gradually narrows from bottom to top. The through groove 24 penetrates the corresponding wall of the locking plate 14 and the slot 25. The two sets of outer ring plates 1 are interconnected. One end of the locking rod 23, away from the bottom set of locking plates 14, extends into the slot 22 through the through groove 24. The through groove 24, which gradually narrows from bottom to top, allows the locking rod 23 to be easily inserted into the slot 22 when the two sets of outer ring plates 1 are closed in a ring-shaped adjustment. The slot 25 is opened on both sides of the side wall of the locking rod 23, and the slot 25 is located in the corresponding slot 22 on the locking rod 23. The clip can be inserted into the slot 25 on the locking rod 23 to complete the latching of the plug.

[0039] The locking mechanism includes a locking plate 26, a pressure plate 27, a pressure groove 28, and a limiting rod 31. The locking plate 26 is disposed in the slot 22. The end of the locking plate 26 near the locking rod 23 is U-shaped, allowing it to be inserted into the slot 25 on the locking rod 23. The pressure plate 27 is disposed on the side of the locking plate 14 away from the outer ring plate 1 and is fixedly mounted on the locking plate 26. The limiting rod 31 is fixedly mounted on both ends of the pressure plate 27. The end of the limiting rod 31 away from the pressure plate 27 slides through the corresponding position on the wall of the locking plate 14. The two sets of limiting rods 31 can drive the pressure plate 27 to move on the locking plate 14. The pressure groove 28 is opened on the side wall of the pressure plate 27 away from the locking plate 14. The pressure groove 28 allows the locking mechanism to be pressed on the pressure plate 27, thereby locking the locking mechanism.

[0040] The locking mechanism includes a bolt 29 and a pressing plate 30. The bolt 29 is threaded onto a set of bottom locking plates 14, and the pressing plate 30 is fixedly mounted on the side wall of the bolt 29. When the bolt 29 is spirally pushed onto the locking plate 14, it can drive the pressing plate 30 to press the pressure groove 28 on the pressure plate 27. When the bolt 29 is fully threaded onto the set of bottom locking plates 14, the pressing plate 30 can restrict the movement of the pressure plate 27, thereby completing the locking of the locking mechanism.

[0041] The connector includes a connecting groove 18, a connecting plate 19, a locking groove 33, a locking block 34, and a locking adjustment groove 35. The locking adjustment groove 35 is formed on the inner sidewall of the two sets of outer ring plates 1. Specifically, the locking adjustment groove 35 is formed at the corresponding movable connection position of the two sets of outer ring plates 1. The locking adjustment groove 35 penetrates the corresponding wall surface of the outer ring plate 1 and communicates with the interior of the adjustment groove 20. The connecting groove 18 is formed on the inner sidewall of the two sets of adjustment rings 15, and the position of the connecting groove 18 corresponds to the position of the locking adjustment groove 35. The connecting plate 19 is disposed in the connecting groove 18, and the top end of the connecting plate 19 is movably mounted on the inner side of the connecting groove 18 on the top set of adjustment rings 15. The connecting plate 19 can move within the connecting groove 18. The locking groove 33 is formed in the connecting groove 18 on the bottom set of adjusting rings 15. The locking block 34 is fixedly installed on the outer side wall of the connecting plate 19, and the position of the locking block 34 corresponds to the position of the locking groove 33. The locking block 34 can be locked in the locking groove 33 by rotating the connecting plate 19. When the adjusting ring 15 is rotated, the end of the connecting plate 19 corresponding to the locking block 34 will move out of the locking groove 35 position, and will be restricted by the inner side of the adjusting groove 20 corresponding to the side wall of the outer ring plate 1, thereby stably connecting the two sets of adjusting rings 15. The locking groove 35 makes it easy to rotate and adjust the connecting plate 19, thereby completing the connection and contact connection of the two sets of adjusting rings 15.

[0042] The connecting piece enables the two sets of adjusting rings 15 to be connected and in contact, which facilitates the contact connection of the two sets of adjusting rings 15 when the locking components on the two sets of outer ring plates 1 are not engaged during the rotational adjustment of the two sets of outer ring plates 1. This allows the two sets of outer ring plates 1 to be effectively separated from the movable connection end. When the locking components on the two sets of outer ring plates 1 are engaged, the two sets of adjusting rings 15 can be connected, allowing the bottom set of adjusting rings 15 to be effectively adjusted through the top set of adjusting rings 15, thereby improving the synchronous clamping of the pipe wall by the multiple sets of clamping plates 11.

[0043] The working principle of this utility model is as follows:

[0044] In use, the top set of outer ring plates 1 is clamped onto the pipe wall. By rotating the bottom set of outer ring plates 1, the two sets of outer ring plates 1 are closed. The locking assembly on the two sets of outer ring plates 1 can lock the two sets of outer ring plates 1. Specifically, the locking rod 23 on the bottom set of locking plates 14 is inserted into the slot 22. By turning the bolt 29, the pressing plate 30 on the bolt 29 pushes the pressure plate 27 to move closer to the slot 22, so that the locking plate 26 is inserted into the slot 25 on the locking rod 23, thereby completing the locking of the two sets of outer ring plates 1. The connecting plate 19 on the two sets of adjusting rings 15 is adjusted by the locking groove 35, so that the locking groove 33 on the connecting plate 19 is engaged in the locking block 34. At this time, a pre-adjustment is performed. The adjusting motor 3 is started to drive the adjusting gear 4 to rotate, so that the adjusting gear 4... The adjusting ring 15 is rotated by the adjusting teeth 17 on the top set of adjusting rings 15, so that the connecting plate 19 moves past the locking groove 35 into the adjusting groove 20. After the pre-adjustment is completed, the adjusting motor 3 drives the adjusting gear 4 to rotate according to the pipe diameter, so that the adjusting ring 15 drives the adjusting plate 16 to move in the inner side of the movable groove 21. Under the limitation of the fixed length of the auxiliary adjusting rod 10, the push rod 9 is driven to move to the inner ring position of the outer ring plate 1, so that the clamping plate 11 on the multiple sets of push rods 9 fits with the pipe wall, thereby completing the adjustment of the pipe diameter. At this time, the inside of the pipe is ultrasonically tested by the detection head 12. During the test, the drive motor 7 is started and can drive the drive wheel 6 to rotate on the pipe wall, thereby pushing the main component to move on the pipe wall until the corrosion test of the chemical pipeline is completed.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
