An automated cleaning device and method for marine pipes

Abstract

This invention relates to the technical field of pipeline cleaning and discloses an automated cleaning device and method for marine pipelines. To solve the problem of excessive waste of cleaning fluid during pipeline cleaning, a cleaning piston and a brush plate are installed on the end of a toothed pusher. When cleaning batches of marine pipe fittings, the cleaning piston is fitted inside the pipe fitting, and the tilting assembly is adjusted to make the tilting frame relatively tilted. This ensures that the cleaning fluid input into the pipe will gather at one end of the cleaning piston and immerse the brush plate. As the brush plate rotates, the inner wall of the pipe containing the cleaning fluid is subjected to high-intensity scrubbing by the brush plate, achieving efficient cleaning of the inside of the pipe. At the same time, the forward movement of the toothed pusher not only changes the brushing position of the brush plate but also uses the cleaning piston to scrape the inside of the pipe, thereby reducing the residue of cleaning fluid. Ultimately, it achieves the effects of tilted water storage cleaning and scraping to prevent residue.

Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and in particular to an automated cleaning device and method for marine pipelines. Background Technology

[0002] In marine systems, marine piping is a crucial component, responsible for transporting media such as oil, water, and gas. Through carefully designed connections between pipes, various required fluid transfer operations can be completed efficiently.

[0003] A search revealed that publication number CN216501289U discloses an internal cleaning device for liquefied gas pipelines, including a main body box. The main body box is provided with several brushing components in the direction of pipeline extension. The brushing components are attached to the inner wall of the pipeline by a pressing member. The main body box is provided with several limiting components for supporting the main body box in the pipeline. The limiting components are evenly distributed along the circumference of the pipeline. The main body box can move along the axial direction of the pipeline by a displacement member.

[0004] Although the cleaning equipment uses rotating brush plates for cleaning and sprays cleaning fluid during the process to dissolve and remove stubborn impurities, thus improving cleaning efficiency, some shortcomings still exist. Specifically, the cleaning fluid often flows directly out from both ends of the pipe after being sprayed, resulting in low utilization of the cleaning fluid. Therefore, a large amount of cleaning fluid is consumed during pipe cleaning, increasing costs. More importantly, marine pipes typically require internal coating after production. However, residual cleaning fluid can severely interfere with the normal operation of the coating process, thereby affecting the quality and efficiency of subsequent pipe manufacturing. Summary of the Invention

[0005] This invention proposes an automated cleaning device and method for marine pipelines, which has the advantages of tilting water storage cleaning and scraping water to prevent residue, thereby solving the problem of excessive waste of cleaning fluid during pipeline cleaning mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automated cleaning device for marine pipelines, comprising: a support base, with a tilting frame movably mounted on one end of its surface, and a tilting assembly connected between the other end of the support base surface and the tilting frame, the tilting assembly enabling the tilting frame to tilt up and down; a support roller, fixed to the surface of the tilting frame, for supporting the pipe fittings; a pipe pressing assembly, disposed on the surface of the tilting frame, for pressing and securing the pipe fittings; a cleaning assembly bracket, fixedly mounted on the end of the tilting frame, and a toothed pusher movably mounted on the top of the cleaning assembly bracket, wherein a motor reducer assembly on the cleaning assembly bracket uses gears to mesh with the bottom of the toothed pusher, enabling the motor reducer assembly to control the directional movement of the toothed pusher; a cleaning piston, fixed to the end of the toothed pusher and fitted inside the pipe fitting; a cleaning motor fixedly mounted on the end of the toothed pusher, and the cleaning motor enabling the brush plate to brush the inside of the pipe fitting.

[0007] Furthermore, the flipping assembly includes a flipping motor and a flipping screw assembly. The flipping motor is movably mounted on one side of the surface of the support base, and the flipping screw assembly is mounted on the output shaft of the flipping motor. The flipping screw assembly and the end of the flipping frame are movably mounted.

[0008] Furthermore, the hose pressing assembly includes a hose pressing cylinder and a hose pressing head. The hose pressing cylinder is connected to an air pump, and the hose pressing head is fixed on the air rod of the hose pressing cylinder.

[0009] Furthermore, a cleaning fluid connector connected to a cleaning fluid pump is fixedly installed at one end of the cleaning piston; and a water connector connected to a water pump is fixedly installed at the other end.

[0010] Furthermore, a support ring is fixedly installed at the end of the cleaning piston, and a filter hole is opened on the outer side of the support ring. An adjusting piston is movably installed inside the cleaning piston, and a coupling sleeve is threadedly connected to the end of the adjusting piston. A transmission shaft rod that is movably installed with the coupling sleeve is fixedly installed on the output shaft of the cleaning motor. An output sleeve is fixedly installed at the end of the adjusting piston, and the outer side of the output sleeve is slidably connected to the inner side of the support ring. An outer protective sleeve is movably installed on the outer side of the support ring, and an axial flow fan blade is fixedly installed on the inner side of the end of the outer protective sleeve. A partition ring is movably installed on the axial flow fan blade shaft, and the outer side of the partition ring and the inner side of the support ring are fitted together. A transmission groove is opened on the outer side of the partition ring to guide the movement of the output sleeve. A return spring is movably connected between the partition ring and the axial flow fan blade shaft. A brush plate is connected to the outer side of the outer protective sleeve via a telescopic rod, and a pull rope passing through the side of the outer protective sleeve is provided between the brush plate and the partition ring.

[0011] Furthermore, the cross-sectional shape of both the drive shaft and the axial fan blade shaft is elliptical.

[0012] Furthermore, there are multiple brush plates, and these brush plates are arranged in a ring at equal angles on the outside of the outer protective sleeve.

[0013] Furthermore, a partition sleeve is movably installed at the end of the support ring sleeve, and a magnet assembly is provided between the end of the partition sleeve and the inner side of the support ring sleeve. A one-way limiting piston that is pushed towards the support ring sleeve by a limiting spring is movably installed in the middle of the adjusting piston. An outwardly protruding switching hook is provided at the end of the output sleeve frame, and a limiting groove corresponding to the switching hook is opened on the outer side of the partition ring frame and at the end of the transmission channel.

[0014] Furthermore, the magnet assembly consists of a pair of mutually attracting ring magnets, one of which is fixed to the inner side of the support ring sleeve and the other is fixed to the end of the partition sleeve.

[0015] A method of using an automated pipeline cleaning device for ships includes the following steps:

[0016] S1. Place the pipe to be cleaned on the support roller, ensuring that the cleaning piston and the pipe are arranged coaxially, and adjust the distance between the pipe and the cleaning assembly bracket.

[0017] S2. Adjust the air pump and the pipe-pressing cylinder to make the pipe-pressing head descend and fix the pipe fitting in the adjusted position.

[0018] S3. Adjust the tilting component to tilt the tilting frame downwards, so that one end of the pipe is higher than the other end, and inject cleaning fluid into the pipe through the cleaning fluid connector.

[0019] S4. Control the cleaning motor to drive the brush plate immersed in the cleaning solution to rotate and perform high-intensity brushing on the inner wall of the pipe.

[0020] S5. During the process of brushing the pipe fittings, the motor reducer group is adjusted to make the gear drive toothed pusher move towards the pipe fittings, pushing the cleaning piston to move further into the pipe fittings. On the one hand, the brush plate continues to brush, and on the other hand, the cleaning piston scrapes the inner wall of the pipe fittings to reduce the residue of cleaning fluid.

[0021] S6. When the cleaning piston extends fully from one end of the pipe, it pushes out all the cleaning fluid inside the pipe and scrapes the inner wall of the pipe to complete the cleaning of the inner wall of the pipe.

[0022] The present invention has the following beneficial effects:

[0023] This invention provides an automated cleaning device and method for marine pipelines, ingeniously integrating a cleaning piston and a brush plate at the end of the toothed pusher frame. This device demonstrates extremely high efficiency and practicality when faced with a large volume of marine pipelines requiring cleaning.

[0024] First, the cleaning piston is fitted into the pipe to be cleaned. This piston is designed with a sealing function to ensure that the liquid does not leak during the cleaning process. Then, the tilting mechanism in the device is precisely adjusted to tilt the frame appropriately. This step is crucial because it ensures that the cleaning fluid injected into the pipe naturally converges at one end of the cleaning piston and fully submerges the brush plate, providing sufficient cleaning medium for subsequent scrubbing operations.

[0025] As the motor drives the brush plates to rotate, the inner wall of the pipe containing the cleaning fluid undergoes high-intensity mechanical scrubbing, effectively removing deposits and achieving efficient cleaning of the pipe's interior. Simultaneously, the toothed pusher not only steadily moves forward along the pipe's axis, continuously changing the brush plate's scrubbing position to ensure every inch of the pipe is thoroughly cleaned, but its front-end cleaning piston also gently scrapes the inner wall of the pipe during its advancement. This design significantly reduces cleaning fluid residue within the pipe.

[0026] In summary, this automated marine pipeline cleaning device, by combining tilting water storage cleaning technology, high-intensity brushing with rotating brush plates, and the water-scraping and residue-preventing function of the cleaning piston, not only significantly improves cleaning efficiency but also effectively ensures cleaning quality.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1-3 As can be seen, the steel frames are fixed together using connectors to form a support base 1 that provides support. The support base 1, with multiple legs at its bottom, can be stably placed in the desired position. The tilting frame 3 is movably connected to the support base 1 using bearing seats. More specifically, from... Figure 1 It is evident that the end shaft of the tilting frame 3 is mounted on a bearing seat fixed to one side of the surface of the support base 1, thereby enabling the tilting frame 3 to rotate vertically around the shaft. Considering the limitations of the actual rotation angle, combined with... Figure 1 and Figure 3As can be seen, a tilting assembly 6 is movably mounted on the surface of the support base 1, relative to the side furthest from the bearing seat. The tilting assembly 6 enables a movable connection between the tilting frame 3 and the end of the support base 1. The tilting assembly 6 mainly includes a tilting motor 600 and a tilting lead screw assembly 601. The tilting motor 600 is movably mounted on one side of the surface of the support base 1 via a motor bracket. The tilting lead screw assembly 601 is mounted on the output shaft of the tilting motor 600. The tilting lead screw assembly 601 includes a threaded sleeve and a lead screw. The lead screw is fixedly connected to the output shaft of the tilting motor 600, ensuring that the lead screw can rotate with the tilting motor 600. The top of the threaded sleeve is movably mounted to the end of the tilting frame 3, and the other end is threadedly connected to the lead screw. Thus, it can be seen that when the tilting motor 600 drives the lead screw to rotate, the relative movement between the threaded sleeve and the lead screw ultimately achieves relative movement between the tilting frame 3 and the support base 1, that is, the tilting frame 3 deflects up and down on the surface of the support base 1. Since the pipe 7 is supported by the support roller 300 fixed to the surface of the tilting frame 3, when one end of the tilting frame 3 deflects, the pipe 7 placed above the support roller 300 will also tilt relatively. To ensure the stability of the pipe 7 placed on the support roller 300, combined with... Figure 1 and Figure 3 As can be seen, the pipe pressing assembly 5 set in the middle of the flipping frame 3 can squeeze the pipe 7, ensuring that the pipe 7 placed on the flipping frame 3 is relatively fixed. The pipe pressing assembly 5 mainly includes a pipe pressing cylinder 500 and a pipe pressing head 501. The pipe pressing cylinder 500 is generally connected to an air pump. When the air pump passes air into the pipe pressing cylinder 500, the pipe pressing head 501 fixed on the air rod of the pipe pressing cylinder 500 will press downward, thereby applying pressure to the pipe 7 placed on the support roller 300, ensuring the stability of the pipe 7 placed on the support roller 300.

[0042] In this first embodiment, in order to achieve cleaning of the inside of pipe 7, such as Figure 1 , Figure 5 and Figure 8 As shown, a cleaning component bracket 8, bolted to the end of the tilting frame 3 and on the same side as the tilting assembly 6, is located. A rectangular mounting groove is provided on the side of the cleaning component bracket 8. Bolts pass through the rectangular groove and are threaded onto the end of the tilting frame 3. Therefore, the cleaning component bracket 8 can move up and down along the rectangular groove, allowing its actual installation position to be adjusted within a certain range, thus facilitating installation and adjustment. A motor reducer assembly 9 is fixedly mounted on the surface of the cleaning component bracket 8, providing power to the gear 10 fixed at its output end. A gear pusher 11 is movably mounted on the top of the cleaning component bracket 8. Figure 8It can be seen that the outer teeth of the bottom toothed pusher 11 and the gear 10 are engaged. When the motor reducer group 9 drives the gear 10 to rotate, the engagement between the gear 10 and the bottom toothed pusher 11 allows the toothed pusher 11 to move left and right under the guidance of the cleaning component bracket 8. The direction of its movement depends on the rotation direction of the motor reducer group 9. Therefore, controlling the forward and reverse rotation of the motor reducer group 9 can make the toothed pusher 11 move closer to / away from the pipe 7. A cleaning piston 12 is bolted to the end of the toothed pusher 11 near the pipe 7. Generally, the outer diameter of the cleaning piston 12 corresponds to the inner diameter of the pipe 7 to be cleaned. This not only ensures that the cleaning piston 12 moves directionally along the pipe 7, but also uses the rubber layer on the outside of the cleaning piston 12 to scrape the inner wall of the pipe 7, thereby reducing the residue of cleaning fluid on the inner wall of the pipe 7. A cleaning motor 14 is fixedly installed at the end of the toothed pusher 11. When the cleaning motor 14 rotates, the brush plate 23 can brush the inner side of the pipe fitting 7, thereby ensuring that the attached substances on the inner side of the pipe fitting 7 can be removed.

[0043] In practical application of this embodiment, the pipe fitting 7 to be cleaned is placed on the support roller 300. By adjusting the height of the cleaning assembly bracket 8, the cleaning piston 12 and the pipe fitting 7 are arranged relatively coaxially. This ensures that the cleaning assembly bracket 8 does not need frequent up-and-down adjustments when cleaning the same batch of pipe fittings 7. To bring the pipe fitting 7 further closer to the cleaning assembly bracket 8, from... Figures 2-4 As can be seen, a reciprocating tube-stopping slide 402 is movably arranged on the surface of the tilting frame 3 between the two support rollers 300. A tube-pushing motor 400 is fixed at the end of the tilting frame 3. A tube-pushing screw 401, which is threadedly connected to the tube-stopping slide 402, is mounted on the output shaft of the tube-pushing motor 400. Therefore, when the tube-pushing motor 400 drives the tube-pushing screw 401 to rotate, the tube-stopping slide 402 can reciprocate along the axial direction of the tube 7 until the tube-stopping slide 402 abuts against the end of the tube 7. The tube 7 can be moved axially by the tube-stopping slide 402, thereby facilitating the adjustment of the distance between the tube 7 and the cleaning component bracket 8. It should be noted that after the tube-stopping slide 402 adjusts the tube 7 into position, the control console 2 fixed to the side of the support base 1 is used for adjustment to start the air pump. The air rod on the tube-pressing cylinder 500 pushes the tube-pressing head 501 downward, fixing the adjusted tube 7 in the adjusted position. After the distance adjustment is completed, the push tube assembly 4 rotates through the push tube motor 400, so that the stop tube slide 402 is relatively far away from the tube 7, thus avoiding the problem that the cleaning piston 12 cannot extend normally due to the subsequent blockage of the tube 7 by the stop tube slide 402.

[0044] After the pipe fitting 7 is clamped and aligned with the central axis of the cleaning piston 12, the control console 2 adjusts the tilting assembly 6 to tilt the top tilting bracket 3 downwards, as follows: Figure 5 As shown, when the right end of the tilting frame 3 rotates clockwise around the left pivot, the left end of the pipe fitting 7 is higher than the right end. (Combined with...) Figure 6 and Figure 7 As can be seen, a cleaning fluid connector 13 is fixedly installed at the end of the cleaning piston 12. The cleaning fluid connector 13 is connected to a cleaning fluid pump, which draws the cleaning fluid into the pipe 7. Since the pipe 7 is at a relative inclination, the cleaning fluid accumulated inside the pipe 7 will simultaneously immerse the brush plate 23. When the control console 2 controls the cleaning motor 14 to rotate the brush plate 23, the brush plate 23 performs high-intensity scrubbing on the inner wall of the pipe 7, thereby removing the deposits inside the pipe 7. During this process, the cleaning fluid remains inside the pipe 7, thus ensuring continuous use of the input cleaning fluid and avoiding waste caused by the cleaning fluid flowing out from the end.

[0045] Furthermore, after the brush plate 23 has finished cleaning the outer area of ​​the pipe fitting 7, the control console 2, through the adjustment of the motor reducer group 9, causes the gear 10 to drive the gear rack pusher 11 to move towards the pipe fitting 7, and the cleaning piston 12 further pushes into the pipe fitting 7. On the one hand, it pushes the brush plate 23 forward to brush; on the other hand, it uses the cleaning piston 12 to scrape the inner side of the pipe fitting 7, thereby reducing the amount of cleaning fluid remaining on the inner wall of the pipe fitting 7. Finally, when the cleaning piston 12 extends from the left end of the pipe fitting 7, it not only pushes all the cleaning fluid inside the pipe fitting 7 outward, but also scrapes the inner wall of the pipe fitting 7 thoroughly, ensuring that no cleaning fluid remains on the inner wall of the pipe fitting 7, thus completing the cleaning of the inner wall of the pipe fitting 7.

[0046] Based on this, since the inner wall will be sprayed after pipe cleaning, in order to further reduce the residue of cleaning solution, combined with Figure 8 As can be seen, a water connector 131 connected to a water pump is fixedly installed at the end of the cleaning piston 12. It should be noted that the drain ports of the water connector 131 and the cleaning fluid connector 13 are located at opposite ends of the cleaning piston 12. After the internal pipe of the pipe fitting 7 is cleaned, during the return stroke of the toothed pusher 11, the pipe fitting 7 is deflected upward by the flipping assembly 6, making the right side of the pipe fitting 7 relatively higher than the left side. Then, clean water is injected into the water connector 131 by the water pump, ensuring that the cleaning piston 12 further washes the inner wall of the pipe fitting 7 with clean water during the return stroke. Then, the inner wall of the pipe fitting 7 is scraped again by the cleaning piston 12, thereby further reducing the residue of cleaning fluid on the inner wall of the pipe fitting 7.

[0047] Example 2 is a further improvement on Example 1. Please refer to [link / reference]. Figure 6 , Figure 7 and Figure 9It can be seen that a support ring 18 is fixedly installed at the end of the cleaning piston 12 and on the side away from the toothed pusher 11. Figure 7 It can be seen that there is a certain gap between the support ring 18 and the cleaning piston 12, and the two are connected by an arc-shaped plate. The cross-sectional shape of the support ring 18 along the axis is "L"-shaped, and a filter hole 180 for filtering the cleaning fluid is opened on its outer side. Figure 6 As shown, when the cleaning fluid flows from the inside of the support ring sleeve 18 to the outside through the filter hole 180, the filter residue is collected on the inside of the support ring sleeve 18. Therefore, when the cleaning fluid rinses the inside of the pipe fitting 7, it can be filtered after passing through the inside of the support ring sleeve 18, thus improving the cleanliness of the cleaning fluid.

[0048] An adjusting piston 16 is movably mounted inside the cleaning piston 12. This adjusting piston 16 can not only rotate inside the cleaning piston 12 but also move along the axial direction of the cleaning piston 12. Figure 6 and Figure 9 It can be seen that a coupling sleeve 151 is threadedly connected to the end of the adjusting piston 16 near the cleaning motor 14. Correspondingly, a transmission shaft 15, which is movably mounted on the output shaft of the cleaning motor 14 and connected to the coupling sleeve 151, is fixedly installed. The cross-sectional shape of the transmission shaft 15 is preferably elliptical. Therefore, when the cleaning motor 14 rotates, it can not only transmit torque to the coupling sleeve 151 through the transmission shaft 15, but also ensure that there is axial movement space between the transmission shaft 15 and the coupling sleeve 151. An output sleeve 21 is fixedly installed at the end of the adjusting piston 16. Figure 6 and Figure 7 As can be seen, the output sleeve 21 is approximately cuboid in shape, and there are multiple cuboids. These multiple output sleeves 21 are fixedly connected to a ring frame at equal angles, and the ring frame is fastened to the end of the adjusting piston 16. For example... Figure 6 As shown, when the cleaning motor 14 drives the adjusting piston 16 to rotate, the adjusting piston 16 can drive the output sleeve 21 to rotate synchronously. The outer side of the output sleeve 21 is slidably connected to the inner side of the support ring sleeve 18. When the output sleeve 21 rotates with the adjusting piston 16, the sweeping motion of the output sleeve 21 on the inner side of the support ring sleeve 18 prevents filter residue from continuously accumulating on the inner side of the support ring sleeve 18 and at the filter hole 180, ultimately making it easier for the cleaning liquid to pass through the filter hole 180.

[0049] Corresponding to the above, in combination Figure 6 , Figure 7 and Figure 9As can be seen, an outer protective sleeve 22 is mounted on the outer side of the support ring sleeve 18 and located outside the filter hole 180, and is movably mounted via a bearing. The outer protective sleeve 22 can rotate using the bearing. An axial flow fan blade 24 is fixedly mounted on the inner side of the end of the outer protective sleeve 22. When the outer protective sleeve 22 rotates, the axial flow fan blade 24 accelerates the flow of the medium around it. Furthermore, the direction of the medium flow around the axial flow fan blade 24 is limited by the rotation direction of the axial flow fan blade 24, for example, by a direction reference. Figure 6 When the axial fan blade 24 rotates clockwise, the medium flows from right to left; similarly, when the axial fan blade 24 rotates counterclockwise, the medium flows in the opposite direction. A partition ring frame 25 is movably mounted on the shaft of the axial fan blade 24, and the outer side of the partition ring frame 25 is fitted into the inner side of the support ring sleeve 18. Guided by the inner side of the support ring sleeve 18 and the shaft of the axial fan blade 24, the partition ring frame 25 can only reciprocate along the axial direction of the shaft of the axial fan blade 24. Preferably, the cross-sectional shape of the shaft of the axial fan blade 24 and the movably mounted part of the partition ring frame 25 is elliptical, ensuring that the partition ring frame 25 can rotate synchronously with the axial fan blade 24. Figure 9 and Figure 10 It can be seen that a transmission channel 251 is provided on the outer side of the partition ring 25 to guide the movement of the output sleeve 21, ensuring that the output sleeve 21 can reciprocate along the transmission channel 251. Under normal conditions, because a return spring 250 is movably connected between the partition ring 25 and the shaft of the axial fan blade 24, the partition ring 25 is always kept relatively close to the axial fan blade 24 due to the elastic force of the return spring 250. Figure 6 As shown. Based on this, the brush plates 23 are connected to the outside of the outer protective sleeve 22 via telescopic rods. There are multiple brush plates 23, arranged in a ring at equal angles on the outside of the outer protective sleeve 22. Restricted by the telescopic rods, the brush plates 23 can only reciprocate along the radial direction of the support ring sleeve 18. Normally, a pull rope 230 passing through the side of the outer protective sleeve 22 is provided between the brush plates 23 and the partition ring frame 25. Combined with the above, the partition ring frame 25 is pushed by the return spring 250, causing it to constantly pull the pull rope 230 with a tendency to move to the left, thus keeping the brush plates 23 tightly against the outside of the support ring sleeve 18.

[0050] Under normal conditions, the cleaning motor 14 stops working, and the partition ring 25, pushed by the return spring 250, pulls the brush plate 23 tightly against the outside of the outer protective sleeve 22 via the pull rope 230. During normal operation, the fixing and tilting of the pipe fitting 7 and the injection of cleaning fluid are as described in Example 1, and will not be elaborated further here.

[0051] When the cleaning motor 14 rotates, power is transmitted through the drive shaft 15 and coupling sleeve 151, causing the adjusting piston 16 to drive the output sleeve 21 to rotate synchronously in the forward direction. This forward rotation causes the output sleeve 21 to drive the isolation ring frame 25 to rotate synchronously in the forward direction. Furthermore, the isolation ring frame 25, through the rotation of the axial fan blades 24, forces the outer protective sleeve 22 to rotate synchronously in the forward direction. (Reference) Figure 6 As shown, at this time, the cleaning fluid on the left side of the cleaning piston 12 has submerged the axial flow fan blade 24. When the axial flow fan blade 24 rotates in the forward direction, the cleaning fluid inside the outer protective sleeve 22 is continuously discharged into the pipe 7 by the guidance of the axial flow fan blade 24. When the cleaning fluid inside the outer protective sleeve 22 decreases, the cleaning fluid inside the pipe 7 is transported from the gap between the support ring sleeve 18 and the cleaning piston 12 into the support ring sleeve 18. After passing through the filter hole 180, the cleaning fluid flows back into the outer protective sleeve 22. It can be seen that by utilizing the rotation of the axial flow fan blade 24, the cleaning fluid can perform real-time autonomous filtration during the brushing of the inner wall of the pipe 7. At the same time, when the outer protective sleeve 22 rotates, the brush plate 23 is subjected to rotation, which increases the centrifugal force generated by the rotation, thereby causing the brush plate 23 to move outward until it contacts the inner side of the pipe 7. During the movement, the pull rope 230 pulls the partition ring frame 25 to compress the return spring 250 relative to it.

[0052] Subsequently, as the toothed pusher 11 pushes the cleaning piston 12 forward, the inner side of the pipe 7 is gradually cleaned. When the cleaning piston 12 disengages from the left end of the pipe 7, the outer side of the brush plate 23 is no longer restricted. Therefore, under the action of centrifugal force, the brush plate 23 extends further outward and is further pulled by the pull rope 230 to compress the return spring 250 of the partition ring frame 25. At this time, the transmission channel 251 also moves along the output sleeve 21. During this movement, the right end of the partition ring frame 25 pushes out the filter residue inside the support ring sleeve 18. Finally, the right end of the partition ring frame 25, which moves to the right, aligns with the right end of the support ring sleeve 18. Due to the continuous rotation of the partition ring frame 25, the filter residue is thrown outward from the gap between the cleaning piston 12 and the support ring sleeve 18, thus cleaning the filter residue. In addition, the rotation of the outer protective sleeve 22 and the partition ring frame 25 causes the residual cleaning liquid to be thrown out. When the cleaning motor 14 stops and the inner side of the pipe 7 is washed again, the cleaning fluid on the left side of the cleaning piston 12 has been ejected. Therefore, the residual cleaning fluid on the left side of the cleaning piston 12 is prevented from dripping onto the inner side of the pipe 7 during the return stroke.

[0053] Further improvements based on the above, combined with Figure 6 , Figure 7 and Figure 9As can be seen, a partition sleeve 19 is movably installed at the end of the support ring sleeve 18. The partition sleeve 19 is a cylindrical body with a through-center. A magnet assembly 20 is provided between the left end of the partition sleeve 19 and the inner side of the support ring sleeve 18. The magnet assembly 20 consists of a pair of mutually attracting annular magnets. One magnet is fixed to the inner side of the support ring sleeve 18, and the other is fixed to the left end of the partition sleeve 19. When the partition sleeve 19 moves away from the support ring sleeve 18, it separates the two. The right end of the partition sleeve 19 is movably installed between the right end and the output sleeve frame 21, allowing relative movement between them. The partition sleeve 19 can also move axially with the output sleeve frame 21. Figure 6 It can be seen that the outer diameter of the partition sleeve 19 is the same as the diameter of the adjusting piston 16. Therefore, when the partition sleeve 19 moves to the right, it can eventually seal the gap between the support ring sleeve 18 and the cleaning fluid connector 13. A one-way limiting piston 17, which is pushed towards the support ring sleeve 18 by the limiting spring 170, is movably installed in the middle of the adjusting piston 16. The one-way limiting piston 17 constitutes a one-way shut-off valve, which only allows the medium on the left side of the cleaning piston 12 to move unidirectionally to the right. However, it should be noted that the one-way shut-off valve can only be opened if the pressure on the left side of the cleaning piston 12 overcomes the elastic force of the limiting spring 170.

[0054] More importantly, combining Figure 9 and Figure 10 It can be seen that the output sleeve 21 has an outwardly protruding switching hook 210 at its end. Correspondingly, the outer side of the partition ring 25, located at the end of the transmission channel 251, has a limiting channel 252 corresponding to the switching hook 210. Under normal conditions, the partition sleeve 19 is restricted by the magnet assembly 20 to retract into the support ring 18, and the distance between the support ring 18 and the cleaning piston 12 is not obstructed. The return spring 250 pushes the partition ring 25 relatively close to the axial fan blade 24. At this time, the brush plate 23 is attached to the outer side of the outer protective sleeve 22, and the switching hook 210 corresponds to the limiting channel 252. Figure 10 As shown in the diagram. When the cleaning piston 12 rotates in the forward direction, the output sleeve 21 will cause the switching hook 210 to deflect away from the limiting channel 252. Therefore, the switching hook 210 will not be inserted into the limiting channel 252, which ensures that, as mentioned above, during the rotation of the output sleeve 21 and the isolation ring 25, the transmission channel 251 can move along the switching hook 210.

[0055] As mentioned above, after the cleaning piston 12 has extended from the left end of the pipe 7, as described in Embodiment 1, the tilt angle of the pipe 7 is changed, and clean water is injected into the right end of the cleaning piston 12 through the water connector 131. Then, the toothed pusher 11 pulls the cleaning piston 12 out to the right along the pipe 7. During this process, the control console 2 controls the cleaning motor 14 to rotate in the reverse direction, causing the switching hook 210 to insert into the limiting channel 252, and driving the isolation ring 25 to rotate in the reverse direction through the output sleeve 21. At this time, the reverse-rotating axial fan blades 24 cause the airflow to flow from left to right, with the direction referenced... Figure 6 Under centrifugal force, the brush plate 23 moves outward and, through the pull rope 230, causes the partition ring frame 25 to move to the right. Since the switching claw 210 is engaged in the limiting channel 252 at this time, when the partition ring frame 25 moves to the right, it pushes the output sleeve frame 21 and the adjusting piston 16 to move synchronously to the right. When the output sleeve frame 21 pulls the partition sleeve 19 to the right, the outer part of the partition sleeve 19 seals the gap between the support ring sleeve 18 and the cleaning piston 12. Afterward, the airflow delivered by the axial fan blades 24 finally gathers inside the support ring sleeve 18. When the airflow pressure inside the support ring sleeve 18 increases, it causes the one-way limiting piston 17 to open. Ultimately, the external airflow passes through the inside of pipe 7, the axial fan blades 24, the inside of the support ring sleeve 18, and the one-way limiting piston 17, and then flows continuously outward from the right side of pipe 7. This results in a continuous airflow inside pipe 7 during the rinsing process, thereby accelerating the drying inside pipe 7 and reducing water residue on the inner side of pipe 7 after cleaning. It should be noted that when the brush plate 23 is thrown outward due to reverse rotation, the distance it moves outward will not exceed the outermost edge of the support ring sleeve 18. This ensures that the brush plate 23 will not come into contact with the inside of pipe 7 during the process of the cleaning piston 12 being pulled out of pipe 7, thus ensuring the cleanliness of the inner side of pipe 7.

[0056] In practical applications, users can optionally install a detection spring 171 at the end of the one-way limiting piston 17, with the end of the detection spring 171 located near the right end of the filter orifice 180. The advantage of this design is that when replacing the cleaning piston 12 to accommodate pipes of different inner diameters, if the pipe is large, the brush plate 23 will move outwards too far, and the partition ring 25 will move further to the right, reducing the actual filtration area of ​​the filter orifice 180. This results in the cleaning fluid on the left side of the cleaning piston 12 not being effectively filtered. Therefore, when the replacement cleaning piston 12 is large, the brush plate 23 will drag the partition ring 25 to the right via the pull rope 230. When the partition ring 25 contacts the detection spring 171 and pushes further to the right, the one-way limiting piston 17 will be forced to open. Given that the left end of fitting 7 is relatively higher than the right end, and the left side of the cleaning piston 12 is filled with cleaning fluid, the cleaning fluid will leak from the end of fitting 7, thus serving as a warning to the user that the cleaning piston 12 being replaced here is too large and needs to be adjusted.
