[0025] The present embodiment provides a pipeline oxide skin cleaning assembly, as shown in Figure 1 and Figure 2 The pipeline oxide skin cleaning assembly comprises a base disc 100 and a plurality of first elastic members 200, the first ends of the plurality of first elastic members 200 are connected to the base disc 100 and are arranged in a circumferential direction of the base disc 100, the second ends of the plurality of first elastic members 200 extend radially outside the base disc 100 and are connected with power scrapers 300, the second ends of the plurality of first elastic members 200 form a contour column extending axially along the base disc 100, and each power scraper 300 is spirally wound on the contour column; the pipeline oxide skin cleaning assembly further comprises a rotating drive member 400, the driving end of the rotating drive member 400 is connected to the tail end of the base disc 100, and the housing is connected with a plurality of support legs 510 arranged in a circumferential direction.

[0026] The present embodiment further provides a pipeline oxide skin cleaning device, which comprises a control assembly and the above-mentioned pipeline oxide skin cleaning assembly, and the rotating drive member 400 of the pipeline oxide skin cleaning assembly is communicatively connected to the control assembly.

[0027] In the pipe oxide scale cleaning assembly provided in this embodiment, multiple first elastic elements 200 are radially distributed on the base plate 100, and the first elastic elements 200 can be compressed or extended along the radial direction of the base plate 100. When the first elastic elements 200 are not subjected to the force of the inner wall of the pipe to be cleaned, the outer ends of the multiple first elastic elements 200 form a contour circle coaxial with the base plate 100. The contour circle extends along its axial direction to form a contour cylinder. Each power scraper 300 is a spiral scraper of the same shape. The multiple power scrapers 300 are all coiled around the contour cylinder and arranged at intervals along its circumference. Then, the outer ends of the multiple power scrapers 300 along the radial direction of the contour cylinder can form a contour cylinder segment coaxial with the base plate 100. When the degree of compression of the first elastic element 200 changes, the outer diameter of the contour cylinder segment changes accordingly. The end of the support leg 510 away from the shell is used to abut against the inner wall of the pipe to be cleaned. The end of the multiple support legs 510 away from the shell forms a contour circle coaxial with the base plate 100.

[0028] When this pipe oxide scale cleaning component is used in a pipe oxide scale cleaning device, the rotating drive component 400 is communicatively connected to an external control component. Specifically, the control component can be a computer or other remote control with a controller. During use, when the first elastic element 200 is not squeezed by the inner wall of the pipe to be cleaned, the outer diameter of the cylindrical section formed by the outer end of the power scraper 300 is at its maximum. This cleaning component is suitable for pipes whose inner diameter is less than or equal to the outer diameter of this cylindrical section. When the cleaning component is inserted into the pipe to be cleaned, preferably with the power scraper 300 facing inward, the inner wall of the pipe to be cleaned squeezes the power scraper 300 inward. The first elastic element 200 is correspondingly compressed by the squeezing force transmitted by the power scraper 300, and the outer ends of the multiple power scrapers 300 abut against the pipe to be cleaned. Next, the outer ends of each support leg 510 abut against the inner wall of the pipe to limit the circumferential rotation of the rotation drive 400 through static friction with the inner wall of the pipe; then, the control component controls the rotation drive 400 to drive the disc to rotate around the first direction, and multiple spiral power scrapers 300 rotate relative to the inner wall of the pipe under the drive of the disc. During this process, the power scrapers 300 can not only scrape the oxide scale on the inner wall of the pipe, but also generate a propulsive force between themselves and the inner wall of the pipe to drive the entire cleaning component forward in relation to the pipe to be cleaned. Thus, the process of a single rotation drive 400 driving the power scraper 300 to rotate enables the power scraper 300 to simultaneously act as a power foot and a scraping blade to thoroughly scrape the inner wall of the pipe along the length of the pipe to be cleaned. The structure is simple and the functionality is strong.

[0029] When the cleaning assembly reaches the end of the pipe to be cleaned, the control component controls the rotating drive 400 to drive the disc to rotate in a second direction opposite to the first direction. Multiple powered scrapers 300, driven by the disc, rotate in the opposite direction relative to the inner wall of the pipe. This performs a secondary scraping of the oxide scale on the inner wall of the pipe, and simultaneously generates a propulsive force between the scraper and the inner wall, propelling the entire cleaning assembly backward. Thus, it simultaneously acts as a power foot and scraper blades to perform a secondary, comprehensive scraping of the inner wall of the pipe until it exits the pipe, completing a comprehensive, multiple-stage cleaning. Alternatively, depending on the severity of the oxide scale in the pipe, the cleaning assembly can be controlled to perform multiple reciprocating scraping operations before exiting the pipe.

[0030] When in use, this pipe scale removal assembly utilizes a single rotating drive component 400 to drive the rotation of the power scraper 300. This allows the power scraper 300 to act as a scraping blade, removing scale from the inner wall of the pipe to be cleaned, while simultaneously acting as a power foot to apply forward or backward thrust to the entire cleaning assembly. The assembly is simple in structure and compact in size, providing excellent pipe cleaning results, eliminating the need for consumables, reducing cleaning costs, and having no limitations on the length of horizontal or vertical pipes to be cleaned. It is also suitable for cleaning pipes with small diameters. Furthermore, the inclusion of the first elastic element 200 in this cleaning assembly enables the power scraper 300 to form... The outer diameter of the cylindrical section is adapted to the inner diameter of the pipe to be cleaned. This not only ensures that the power scraper 300 effectively scrapes and cleans the inner wall of the pipe during the cleaning process, but also allows the power scraper 300 to elastically extend and retract to adapt to the unevenness of the inner wall of the pipe, thereby increasing the applicability of the cleaning component. It can also effectively reduce jamming and damage caused by rigid collision between the power scraper and the protrusions of the inner wall of the pipe during the cleaning process. In addition, when this pipe oxide scale cleaning component is used in a pipe oxide scale cleaning device, the operator only needs to operate the external control component to control the rotation drive 400 during the cleaning process, which makes the operation more convenient and reduces the labor cost of pipe cleaning.

[0031] Specifically, when the first elastic element 200 is not subjected to the force of the inner wall of the pipe to be cleaned, the outer diameter of the contoured cylindrical section can be 0.05-0.1mm larger than the inner diameter of the pipe to be cleaned; the outer diameter of the contoured circle formed by the multiple support legs 510 away from the housing can be 0.05-0.1mm smaller than the pipe to be cleaned; this cleaning assembly can be used for cleaning small-diameter pipes with an inner diameter of 30mm-40mm, and is also suitable for cleaning large-diameter pipes.

[0032] In this embodiment, as Figure 2 and Figure 3As shown, the first end of the support leg 510 is hinged to the housing, and the second end is inclined toward the tail end of the housing. A second elastic element 530 is connected between the support leg 510 and the housing. When the second elastic element 530 is compressed, it is used to push the support leg 510 to rotate away from the housing. When the second elastic element 530 is not subjected to external force, it is approximately in a naturally extended state. At this time, the outer diameter of the contour circle formed by the second end of the support leg 510 is at its maximum. The cleaning component is adapted to the pipe to be cleaned with an inner diameter less than or equal to the outer diameter. When the cleaning component is placed into the pipe to be cleaned, the inner wall of the pipe presses the second end of the support leg 510 inward, and the second elastic element 530 is compressed accordingly so that the contour circle formed by the second end of the support leg 510 fits the pipe to be cleaned. The elastic force applied by the second elastic element 530 to the support leg 510 outward can ensure that the second end of the support leg 510 abuts against the inner wall of the pipe, thereby increasing the applicability of the cleaning component and effectively reducing the occurrence of jamming or other situations caused by the rigid collision between the second end of the support leg 510 and the protrusion of the inner wall of the pipe during the cleaning process, thereby ensuring the smooth forward or backward movement of the cleaning component.

[0033] Furthermore, since the support leg 510 can rotate and adjust to the inner wall of the pipe under the combined action of the second elastic element 530 and the inner wall of the pipe, the cleaning assembly can be used not only for cleaning straight pipes, but also for cleaning curved pipes and pipes with bends. Specifically, when cleaning curved pipes and bends, the first elastic element 200 can make the power scraper 300 adjust accordingly to the changes in the inner wall of the pipe, and the second elastic element 530 can make the support leg 510 change accordingly to the changes in the inner wall of the pipe, so that the cleaning assembly can pass smoothly through curved pipes and bends, and the power scraper 300 can scrape them in close contact during the process, thereby further improving the applicability of the cleaning assembly.

[0034] Specifically, in this embodiment, as Figure 2 and Figure 3 As shown, the second end of the support leg 510 is rotatably connected to a roller 520 via a rotating shaft. The axial direction of the roller 520 is perpendicular to both the extension direction of the support leg 510 and the axial direction of the base plate 100. When the cleaning assembly is placed inside the pipe to be cleaned, the roller 520 abuts against the inner wall of the pipe and can roll relative to the inner wall of the pipe along the extension direction of the pipe to be cleaned under the propulsion of the power scraper 300. During the forward or backward movement of the cleaning assembly in the pipe to be cleaned, the support leg 510 experiences rolling friction with the inner wall of the pipe through the roller 520, which has relatively low friction. The circumferential relative movement between the roller 520 and the inner wall of the pipe results in relatively high static friction. This ensures that the support leg 510 provides circumferential limitation to the rotating drive component 400, while reducing the resistance caused by the support leg 510 to the forward or backward movement of the cleaning assembly. Consequently, the driving load of the rotating drive component 400 is reduced, and the smoothness of the movement of the cleaning assembly is improved.

[0035] Optionally, in this embodiment, as Figure 2 and Figure 3As shown, the first elastic element 200 is connected to an adjusting component 600, which is used to adjust the compression degree of the first elastic element 200. The adjusting component 600 is communicatively connected to a control component, which is used to control the operation of the adjusting component 600. During the cleaning process, when the power scraper 300 gets stuck with the inner wall of the pipe to be cleaned, the adjusting component 600 can be controlled by the control component to further compress the first elastic element 200, thereby reducing the outer diameter of the cylindrical section formed by the power scraper 300 and releasing the stuck situation between the power scraper 300 and the inner wall of the pipe. Subsequently, the adjusting component 600 is controlled by the control component to return to its initial position, the first elastic element 200 returns to its initial compression degree accordingly, and drives the power scraper 300 to return to its initial position. The power scraper 300 abuts against the inner wall of the pipe again, and the rotating drive component 400 drives the power scraper 300 to scrape the inner wall of the pipe again and push the entire cleaning component to continue to move forward or backward. The adjustment of component 600 can enable the cleaning component to automatically unblock inside the pipe, thereby further improving the functionality and ease of use of the cleaning component.

[0036] Specifically, the adjustment component 600 can be a single component, which can simultaneously adjust the compression degree of all the first elastic elements 200; or there can be multiple adjustment components 600, which can adjust the compression degree of multiple first elastic elements 200 one by one.

[0037] Optionally, in this embodiment, as Figure 2As shown, the first elastic element 200 includes a spring, and the adjustment assembly 600 includes an adjustment drive connected to the base plate 100 and a screw 610 passing through the first elastic element 200. The end of the screw 610 facing the base plate 100 is movably fitted with a first stop 620 and screwed with a nut 640, and the end facing away from the base plate 100 is provided with a second stop 630. The first stop 620 is sandwiched between the first end of the first elastic element 200 and the nut 640, and the second stop 630 abuts against the second end of the first elastic element 200. The drive end of the adjustment drive is connected to the nut 640 and is used to drive the nut 640 to rotate relative to the screw 610. There are multiple adjustment components 600, each corresponding to a different first elastic element 200. Specifically, each adjustment component 600 includes an adjustment drive component such as a motor. The drive end of the adjustment drive component is coaxially connected to the nut 640. For example, a connecting arm can be provided at the drive end of the motor, and the connecting arm is connected to the nut 640. When the cleaning component is used for the first time, the compression degree of the first elastic element 200 is adjusted by the adjustment component 600 according to the inner diameter of the pipe to be cleaned. Or, if the cleaning component gets stuck with the pipe to be cleaned during the cleaning process, the control component can control the adjustment drive component to start and drive the corresponding nut 640 to rotate, thereby reducing the distance between the first stop 620 and the second stop 630. The first elastic element 200 is compressed by the first stop 620, the screw 610 and the second stop 630 to reduce the radial extension length of the power scraper 300 along the base plate 100, thereby realizing the adjustment of the outer diameter of the contour cylindrical section formed by multiple power scrapers 300. Similarly, after the jamming is released, the adjusting drive can be controlled to rotate the nut 640 in the opposite direction to loosen the first stop 620. The first elastic member 200 in the compressed state pushes the first stop 620 against the nut 640, thereby reducing the compression degree of the first elastic member 200, so as to increase the extension length of the power scraper 300 along the radial direction of the base plate 100, and correspondingly realize the adjustment of the outer diameter of the contour cylindrical section formed by the multiple power scrapers 300.

[0038] Specifically, the adjustment component 600 and the first elastic element 200 can both be disposed on the front end face of the base plate 100 or on the outer peripheral surface of the base plate 100. Preferably, a receiving cavity can be provided on the outer peripheral surface of the base plate 100 to receive the adjustment drive component.

[0039] In this embodiment, as Figures 1-3As shown, a front-facing camera 710 is provided at the front end of the base plate 100. In use, the front-facing camera 710 is communicatively connected to the control component and can display images or videos captured by the front-facing camera 710 through the control component or an additional display screen. Specifically, during the cleaning process, the cleaning component is located inside the pipe to be cleaned. The front-facing camera 710 can capture real-time images of the internal condition of the pipe in front of the cleaning component and upload them to the control component. Operators can use images or videos to understand the internal condition of the pipe to be cleaned, as well as the cleaning progress and operating status of the cleaning component, and make corresponding adjustments to the cleaning component based on the real-time situation. Specifically, the severity of the oxide scale inside the pipe to be cleaned can be understood based on images or videos, and the rotation speed of the rotating drive component 400 can be controlled accordingly, as can the scraping speed of the power scraper 300 on the inner wall of the pipe to be cleaned and the forward speed of the power scraper 300 pushing the entire cleaning component forward. Alternatively, images or videos can be used to detect if the cleaning component is stuck, and the adjusting component 600 can be controlled to compress the first elastic element 200 to free the cleaning component, thereby further improving the functionality and ease of use of the cleaning component.

[0040] In this embodiment, as Figure 2 and Figure 3 As shown, a side camera 720 can also be installed on the side of the housing. In use, the side camera 720 is communicatively connected to the control component. During cleaning, the side camera 720 is located behind the power scraper 300 and can capture images of the inner wall of the pipe after being scraped by the power scraper 300. The operator can determine the scraping speed and number of times the cleaning component scrapes the inner wall of the pipe based on the scraping effect, and correspondingly control the rotation speed and direction of the rotating drive component 400. Specifically, if the oxide scale on the inner wall of the pipe is severe, and a large amount of oxide scale remains in a local area after the power scraper 300 scrapes the inner wall, the rotating drive component 400 can be controlled to drive the power scraper 300 to repeatedly scrape that area multiple times, thereby further improving the functionality and ease of use of the cleaning component.

[0041] Optionally, in this embodiment, as Figure 2As shown, the housing is equipped with an electromagnet 810. During use, the electromagnet 810 is communicatively connected to the control component, which can control the opening and closing state of the electromagnet 810. During the initial cleaning process, the electromagnet 810 is in the off state. When the pipe to be cleaned contains a horizontal pipe, a bend, or an elbow, after cleaning, the control component can open the electromagnet 810. As the cleaning component passes through the bend, elbow, or horizontal pipe, the oxide scale scraped off inside the pipe can be attracted to the electromagnet 810 by its magnetic attraction. Correspondingly, the cleaning component can carry the electromagnet 810 and the attracted oxide scale out of the pipe, thus completing both the scraping of oxide scale inside the pipe and the cleaning of the scraped-off oxide scale. This reduces the need for subsequent cleaning steps for the scraped-off oxide scale, further improving the functionality of the cleaning component and reducing the workload of the operator.

[0042] In this embodiment, as Figure 3 As shown, the pipe oxide scale cleaning assembly also includes a receiving bag 900, which includes a bag body 910 and a support ring 920 supporting the opening of the bag body 910. The support ring 920 is connected to the rear of the housing. The housing is provided with a push drive component 820, and an electromagnet 810 is connected to the drive end of the push drive component 820. The push drive component 820 is used to push the electromagnet 810 through the support ring 920 into the bag body 910 or through the support ring 920 out of the bag body 910. The receiving bag 900 is provided on the rear side of the housing to work with the electromagnet 810, and its push drive component 820 is communicatively connected to the control component during use. The support ring 920 can keep the opening of the bag body 910 open to ensure that the electromagnet 810 can enter and exit the bag body 910. The flexible bag body 910 does not increase the radial dimension of the cleaning assembly, thereby reducing interference with the inner wall of the pipe during cleaning and ensuring smooth forward and backward movement of the cleaning assembly.

[0043] Initially, the drive unit 820 is in the retracted state, and the electromagnet 810 is located outside the containing bag 900. When the electromagnet 810 is activated, it can magnetically attract the oxide scale scraped off from the pipe. When there is a lot of oxide scale covering the outside of the electromagnet 810, it will block it and weaken its magnetic attraction. At this time, the drive unit 820 can be activated by the control component. The drive unit 820 drives the electromagnet 810 to carry the oxide scale adsorbed on it into the bag 910 through the support ring 920. Then, the electromagnet 810 is controlled to close, and the oxide scale adsorbed on the electromagnet 810... The oxide scale falls into the bag 910. There is almost no oxide scale adhering to the electromagnet 810. Then, the drive component 820 is pushed to drive the electromagnet 810 out of the container bag 900 and return it to the initial position. The electromagnet 810 is then restarted to magnetically absorb and collect the oxide scale in the pipe again until the oxide scale in the entire pipe is collected and magnetically attracted clean. During the process of collecting oxide scale, the rotation of the drive component 400 can be controlled to drive the power scraper 300 to control the start and stop of the entire cleaning component to cooperate with the electromagnet 810 to magnetically attract and collect the oxide scale.

[0044] The inclusion bag 900 is designed to contain the oxide scale attracted by the electromagnet 810, ensuring the magnetic attraction of the electromagnet 810 to the oxide scale and increasing the amount of oxide scale carried by the cleaning component. This allows the cleaning component to completely clean the oxide scale in a single stroke without having to move back and forth multiple times, thereby further improving the functionality and ease of use of the cleaning component.

[0045] Specifically, in this embodiment, the support ring 920 is coaxial with the base plate 100, and the front end of the support ring 920 is surrounded by an elastic body, which is flared in the direction away from the support ring 920. The elastic edge can be made of elastic materials such as rubber or silicone. The outer diameter of the elastic edge is approximately equal to or slightly smaller than the inner diameter of the pipe to be cleaned. In use, the cleaning component is placed inside the pipe to be cleaned, and the elastic edge is approximately fitted inside the pipe. As the cleaning component moves forward, the power scraper 300 scrapes off the oxide scale from the front side, and the elastic edge can perform a secondary scraping of the scraped oxide scale from the rear side of the power scraper 300, thereby scooping the scraped oxide scale into the bag 910. This achieves simultaneous scraping of oxide scale by the power scraper 300 and collection of the scraped oxide scale by the elastic edge and the containing bag 900, thereby improving the functionality of the cleaning component, reducing the magnetic attraction load of the electromagnet 810, and improving the cleaning efficiency of the cleaning component on the pipe. In addition, during the cleaning process, the elastic edge can adapt to the shape of the inner wall of the pipe and undergo elastic deformation to reduce interference and jamming between the elastic edge and the inner wall of the pipe, thereby ensuring the smooth operation of the cleaning component.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
