Description

Technical Field

[0001] This application relates to the field of pipe oxide scale removal technology, and in particular to an automatic pipe oxide scale removal device in all positions. Background Technology

[0002] Oxide scale refers to an oxide film that forms on the surface of metal pipes. This phenomenon is common in metal materials under high temperature, humid, or oxygen-rich environments, especially in industrial pipelines, hot water pipelines, and some chemical equipment. The presence of oxide scale can lead to further corrosion of the base metal, especially when the oxide scale is uneven or cracked. Furthermore, it can affect the flow of fluids within the pipeline, increasing flow resistance. Therefore, when using industrial pipelines, it is necessary to clean the inside of the pipeline to remove oxide scale and other deposits. This ensures normal pipeline operation and extends the pipeline's service life. After thoroughly removing the oxide scale, an anti-corrosion coating should be applied to the inner surface of the pipeline, depending on the specific usage conditions, to isolate oxygen and moisture, further improving the pipeline's service life and operational safety.

[0003] While there are many methods for removing oxide scale, they are still somewhat insufficient for comprehensive deoxidation of pipelines. For example, mechanical scraping is suitable for large pipelines, but it is difficult to remove oxide scale from welded joints. Chemical cleaning removes oxide scale through a chemical reaction by introducing pickling solutions; however, chemical reactions require a long time, may not be thorough enough for deeply embedded oxide scale, and the acidic contamination level is high, making waste liquid difficult to treat. Summary of the Invention

[0004] The purpose of this application is to provide an automatic oxide scale removal device for pipelines at all locations, which solves the problem of difficulty in removing oxide scale from pipelines in all directions in the prior art.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: This application provides an automatic oxide scale removal device for pipelines at all positions, comprising:

[0006] ontology,

[0007] A drive assembly, disposed on the main body, includes a power supply, a drive motor, and a permanent magnet roller. The drive motor is used to drive the permanent magnet roller to rotate, thereby driving the main body to move.

[0008] The deoxidation component, connected to the main body, includes a vertical guide rail. A reciprocating motor is mounted on the top of the vertical guide rail. A crank is connected to the output end of the reciprocating motor. A rocker arm is rotatably connected to the crank. A horizontal guide rail is slidably connected to the vertical guide rail. A first guide rail and a second guide rail are arranged opposite to each other within the horizontal guide rail. A first slider is slidably connected to the first guide rail at the end of the crank. A second slider is slidably connected to the second guide rail at the end of the rocker arm. A limiting groove is provided on one side of the second guide rail. A connecting member is provided on the rocker arm. The connecting member passes through the limiting groove and is connected to the laser emitter. The reciprocating motor can drive the laser emitter to perform a semi-elliptical reciprocating motion.

[0009] In this design, a permanent magnet roller adheres to the pipe wall using magnetic force, ensuring stable movement of the device. Driven by a linear motor, the permanent magnet roller propels the entire device in a circular motion along the pipe wall, achieving comprehensive cleaning. In use, the device is first placed on the pipe wall, ensuring the area to be cleaned is within the laser emitter's trajectory. Then, driven by the drive assembly, the laser emitter begins its circular motion along the pipe wall, removing oxide scale. When encountering difficult-to-clean areas such as pipe weld seams, the reciprocating motor is activated, causing the laser emitter to perform a semi-elliptical reciprocating motion. This semi-elliptical trajectory conforms to the curvature of the seam, more effectively cleaning oxide scale from these complex areas, ensuring thorough and uniform cleaning. This design enables rapid and accurate cleaning of oxide scale from pipe walls using the laser emitter, improving cleaning efficiency. Through the coordinated operation of the drive assembly and the deoxidation assembly, this device is suitable for cleaning pipes of different diameters. The reciprocating motor enables the laser emitter to perform a semi-elliptical reciprocating motion, achieving precise cleaning of difficult-to-clean areas such as pipe weld seams.

[0010] Optionally, the permanent magnet roller is frustum-shaped.

[0011] The frustum-shaped permanent magnet rollers allow the device to rotate around the pipe wall while simultaneously advancing along the pipe's axial direction. This enables the device to gradually penetrate the pipe, achieving automated cleaning and significantly improving cleaning efficiency.

[0012] Optionally, the connector includes a focusing slide rail, a carrier plate is disposed within the focusing slide rail, and an adjusting bolt is provided on the top of the focusing slide rail. One end of the adjusting bolt passes through the focusing slide rail and is connected to the carrier plate. Rotating the adjusting bolt can move the carrier plate. Adjusting the adjusting bolt can adjust the distance between the laser emitter and the pipe wall, thereby achieving the purpose of laser focusing.

[0013] Optionally, the deoxidation component is connected to the body via a positioning component, the positioning component including: a linear motor, the linear motor having a translation slider, the linear motor being used to drive the translation slider to move linearly, and the translation slider being connected to the vertical guide rail.

[0014] Users can adjust the relative position between the deoxidation component and the main body by controlling the movement of the linear motor, according to the specific conditions of the pipe wall and the cleaning needs, to adapt to cleaning operations in different environments.

[0015] Optionally, the carrier is provided with an air nozzle, and the body is provided with an air compressor connected to the air nozzle, and the air nozzle is located on the movement path of the laser emitter.

[0016] Laser emitters may accumulate heat during prolonged high-intensity operation, affecting their performance and lifespan. Air nozzles, by spraying high-pressure airflow, can effectively remove heat from the laser emitter and its surrounding area, achieving a cooling effect and protecting the laser emitter from overheating damage. Furthermore, when cleaning oxide scale from pipe walls, the laser emitter may generate tiny oxide scale fragments. If these fragments are not removed promptly, they may affect the focusing of the laser beam and the cleaning effect. The airflow from the air nozzles can promptly blow away these fragments, ensuring that the laser beam can continuously and effectively act on the pipe wall. In some difficult-to-clean areas, such as welded joints in pipes, the high-pressure airflow from the air nozzles can work synergistically with the laser beam to form a "gas-light" composite cleaning mechanism. This mechanism can more effectively peel off and remove stubborn oxide scale layers, improving cleaning quality and efficiency.

[0017] Optionally, an industrial camera is also included, which is connected to the vertical guide rail via an adjustment assembly. The industrial camera can be used to photograph the oxide scale on the pipe, allowing users to easily understand the oxidation status inside the pipe.

[0018] Optionally, the adjustment assembly includes: a fixed frame, a first adjustment rod, and a second adjustment rod. The fixed frame is connected to the vertical guide rail, and the first adjustment rod is connected to the fixed frame. The first adjustment rod has a first adjustment groove, and the second adjustment rod has a second adjustment groove. The first adjustment rod and the second adjustment rod are connected via an adjustment knob, and the second adjustment rod is connected to the industrial camera. The position of the industrial camera can be adjusted and fixed using the adjustment assembly.

[0019] Optionally, a microprocessor is also included, which is signal-connected to both the industrial camera and the laser emitter. The microprocessor receives image data transmitted from the industrial camera and processes and analyzes it. The microprocessor embeds a pre-trained deep learning model that can automatically identify and classify the degree of oxide scale in the image. Based on a pre-established mapping relationship between oxide scale thickness and laser threshold, the microprocessor can classify the surface oxidation degree into three types: light, moderate, and heavy. After the microprocessor classifies the image, the laser emitter uses the laser threshold corresponding to the classification result for cleaning. For example, for lightly oxidized areas, the laser emitter may use a lower laser power; while for heavily oxidized areas, it may use a higher laser power. This automatic identification function can accurately determine the degree of oxide scale on the pipe wall, avoiding the subjectivity and error of manual judgment.

[0020] Compared with existing technologies, the beneficial effects achieved by this application are as follows: In this invention, the permanent magnet roller is magnetically attached to the pipe wall, ensuring stable movement of the device on the pipe. Driven by a linear motor, the entire device can move in a circular motion along the pipe wall. This motion mode allows the laser emitter to evenly cover the pipe wall, thereby achieving comprehensive cleaning of the pipe. When encountering difficult-to-clean areas such as pipe weld cuts, the reciprocating motor is activated, and the laser emitter will perform a semi-elliptical reciprocating motion. The semi-elliptical motion trajectory can conform to the curvature of the cut, thereby more effectively cleaning the oxide scale in these complex areas, ensuring thorough and uniform cleaning. In summary, this invention achieves automatic oxide scale removal from all positions of the pipe. This not only improves cleaning efficiency but also reduces the need for manual intervention, making pipe cleaning work more intelligent and automated. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0030] Example 1

[0031] This embodiment describes an automatic oxide scale removal device for pipelines in all positions, referencing... Figures 1 to 3The automatic oxide scale removal device for pipelines in this embodiment includes a main body 1, on which a drive assembly 2 is provided. The drive assembly 2 includes a power supply 21, a drive motor 22, and a permanent magnet roller 23. The power supply 21 can be an external power supply or a built-in battery; in this embodiment, a lithium battery is used. The drive motor 22 drives the permanent magnet roller 23 to rotate, thereby moving the main body 1. Further, the main body 1 also includes an oxide removal assembly 3, which includes a vertical guide rail 31. A reciprocating motor 32 is located at the top of the vertical guide rail 31. A crank 33 is connected to the output end of the reciprocating motor 32. A rocker arm 34 is rotatably connected to the crank 33. A horizontal guide rail 35 is slidably connected to the vertical guide rail 31. The horizontal guide rail 35 contains a first guide rail 351 and a second guide rail 352. A first slider 331 slidably connected to the first guide rail 351 is located at the end of the crank 33, and a slider 331 slidably connected to the second guide rail 352 is located at the end of the rocker arm 34. The second slider 341 is slidably connected. A limiting groove 353 is located on one side of the second guide rail 352. A connecting member 36 is provided on the rocker arm 34. The connecting member 36 passes through the limiting groove 353 and connects to the laser emitter 37. In this embodiment, the connecting member 36 includes a focusing slide rail 361. A carrier plate 362 is provided inside the focusing slide rail 361. An adjusting bolt 363 is provided at the top of the focusing slide rail 361. One end of the adjusting bolt 363 passes through the focusing slide rail 361 and connects to the carrier plate 362. Rotating the adjusting bolt 363 can move the carrier plate 362. Adjusting the adjusting bolt 363 can adjust the distance between the laser emitter 37 and the pipe wall, thereby achieving laser focusing. Rotating the reciprocating motor 32 can drive the laser emitter 37 to perform a semi-elliptical reciprocating motion.

[0032] In use, the permanent magnet roller 23 uses magnetic force to adhere to the pipe wall, ensuring stable movement of the device on the pipe. Driven by the linear motor 61, the permanent magnet roller 23 can drive the entire device to move in a circular motion along the pipe wall, achieving comprehensive cleaning of the pipe wall. In use, the device is first placed on the pipe wall, ensuring the area to be cleaned is within the trajectory of the laser emitter 37. Then, driven by the drive component 2, the laser emitter 37 begins to move in a circular motion along the pipe wall, cleaning the oxide scale. When encountering difficult-to-clean areas such as pipe weld cuts, the reciprocating motor 32 is activated, and the laser emitter 37 will perform a semi-elliptical reciprocating motion. The semi-elliptical motion trajectory can conform to the curvature of the cut, thus more effectively cleaning the oxide scale in these complex areas, ensuring thorough and uniform cleaning. This solution, through the laser emitter 37, can quickly and accurately clean the oxide scale on the pipe wall, improving cleaning efficiency. Through the coordinated work of the drive component 2 and the deoxidation component 3, this device can meet the cleaning needs of pipe walls of different diameters. Driven by the reciprocating motor 32, the laser emitter 37 can perform a semi-elliptical reciprocating motion, enabling precise cleaning of difficult-to-clean areas such as pipe weld cuts.

[0033] refer to Figure 4 In this embodiment, the permanent magnet roller 23 is frustum-shaped. The frustum-shaped permanent magnet roller 23 allows the device to rotate around the pipe wall while simultaneously advancing along the pipe's axial direction. This enables the device to gradually penetrate deeper into the pipe, achieving fully automated cleaning and significantly improving cleaning efficiency. In this embodiment, a traction rope is provided on the main body; after the device has penetrated deep into the pipe and completed the cleaning work, it can be pulled out of the pipe using the traction rope.

[0034] Furthermore, this example also includes a controller for regulating the drive motor 22 and the reciprocating motor 32. The controller is an industrial wireless controller capable of precisely controlling the rotation speed of the drive motor 22, thereby adjusting the movement speed of the laser emitter 37 on the pipe wall. The cleaning speed of the laser emitter 37 is adjusted according to different cleaning needs and the specific conditions of the pipe wall to achieve the best cleaning effect. When cleaning complex locations such as pipe welded joints, the controller can activate the reciprocating motor 32, causing the laser emitter 37 to perform a semi-elliptical reciprocating motion. This motion mode can more effectively clean these hard-to-reach areas, ensuring the comprehensiveness and thoroughness of the cleaning operation.

[0035] Example 2:

[0036] Based on the same inventive concept as Embodiment 1, refer to Figure 5 and Figure 6 The difference lies in that, in this embodiment, the deoxidation component 3 is connected to the body 1 via a positioning component 6. The positioning component 6 includes a linear motor 61, on which a translation slider 62 is mounted. The linear motor 61 drives the translation slider 62 to move linearly, and the translation slider 62 is connected to a vertical guide rail 31. Users can adjust the relative position between the deoxidation component 3 and the body 1 by controlling the movement of the linear motor 61 according to the specific conditions of the pipe wall and cleaning requirements, thus adapting to cleaning operations in different environments.

[0037] refer to Figure 4In this embodiment, the carrier 362 is equipped with an air nozzle 38, and an air compressor connected to the air nozzle 38 is located inside the main body. The air nozzle is positioned along the movement path of the laser emitter. During prolonged high-intensity operation, the laser emitter 37 may accumulate heat, affecting its performance and lifespan. The air nozzle 38, by spraying a high-pressure airflow, can effectively remove heat from the laser emitter 37 and its surrounding area, achieving a cooling effect and protecting the laser emitter 37 from overheating damage. Furthermore, when cleaning oxide scale from pipe walls, the laser emitter 37 may generate tiny oxide scale fragments. If these fragments are not removed promptly, they may affect the focusing of the laser beam and the cleaning effect. The airflow from the air nozzle 38 can promptly blow away these fragments, ensuring that the laser beam can continuously and effectively act on the pipe wall. In some difficult-to-clean areas, such as pipe weld joints, the high-pressure airflow from the air nozzle 38 can work synergistically with the laser beam to form a "gas-light" composite cleaning mechanism. This mechanism can more effectively peel off and remove stubborn oxide scale layers, improving cleaning quality and efficiency.

[0038] This example also uses an industrial camera 4 to photograph the oxide scale on the pipe, allowing users to understand the oxidation status inside the pipe. Specifically, the industrial camera 4 is connected to the vertical guide rail 31 via an adjustment assembly 5. The adjustment assembly 5 includes: a fixing frame 51, a first adjusting rod 52, and a second adjusting rod 53. The fixing frame 51 is connected to the vertical guide rail 31, and the first adjusting rod 52 is connected to the fixing frame 51. The first adjusting rod 52 has a first adjusting groove 54, and the second adjusting rod 53 has a second adjusting groove 55. The first adjusting rod 52 and the second adjusting rod 53 are connected via an adjusting knob 56, and the second adjusting rod 53 is connected to the industrial camera 4. The position of the industrial camera 4 can be adjusted and fixed using the adjustment assembly 5.

[0039] To enable the device to adapt to pipes with varying degrees of oxidation, this embodiment uses a microprocessor to automatically adjust the power of the laser emitter 37. Specifically, the microprocessor is connected to both the industrial camera 4 and the laser emitter 37. The microprocessor receives image data transmitted from the industrial camera 4 and processes and analyzes it. The microprocessor embeds a trained deep learning model that can automatically identify and classify the degree of oxide scale in the images. Based on a pre-established mapping relationship between oxide scale thickness and laser threshold, the microprocessor can categorize surface oxidation into three types: light, moderate, and heavy. After the microprocessor classifies the image, the laser emitter 37 uses the laser threshold corresponding to the classification result for cleaning. For example, for lightly oxidized areas, the laser emitter 37 may use a lower laser power; while for heavily oxidized areas, it may use a higher laser power. This automatic identification function accurately determines the degree of oxide scale on the pipe wall, avoiding the subjectivity and errors of manual judgment.

[0040] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
