Description

Technical Field

[0001] This invention relates to the field of smart urban water supply technology, and in particular to a robot for repairing urban water supply pipelines. Background Technology

[0002] Smart urban water supply is an important infrastructure for urban construction, playing a crucial role in ensuring the stable development of the urban economy and improving people's living standards. Among these aspects, the laying and management of urban water supply pipelines are of paramount importance.

[0003] During long-term use, water supply pipelines are prone to corrosion due to the continuous transport of water. This can lead to localized corrosion and rot. If the corrosion is not addressed, it will worsen and eventually cause perforation, resulting in leaks and severely impacting the normal water delivery process.

[0004] Currently, the usual way to deal with the corrosion on the inner wall of the water supply pipes mentioned above is to manually add an anti-corrosion layer to the corroded part of the inner wall of the water supply pipe, either by applying an anti-corrosion paint to the corroded part or by covering and fixing a stainless steel plate on the corroded part.

[0005] However, the existing treatment methods described above only address the localized corrosion on the inner wall of the water supply pipe, leaving the surrounding areas exposed and susceptible to further corrosion. Furthermore, these localized treatment methods cannot comprehensively enhance the corrosion resistance of the water supply pipe's inner wall, making it prone to fouling and nodule formation, and failing to guarantee the cleanliness of the pipe's interior. Manually treating localized corrosion on the inner wall of the water supply pipe requires workers to precisely locate each corroded section, which is difficult and labor-intensive. Therefore, the existing treatment methods cannot effectively and comprehensively repair the corrosion on the inner wall of the water supply pipe. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively and comprehensively repair corroded parts on the inner wall of water supply pipelines, and to propose a city water supply pipeline repair robot.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a city water supply pipeline repair robot, including a vehicle, a feeding port on one side of the vehicle, and a rolling mechanism inside the vehicle, which is used to roll and press a stainless steel inner liner into a ring structure.

[0009] The rolling mechanism is provided with an inner lining mechanism on one side, and the inner lining mechanism is located on the side of the vehicle. The inner lining mechanism is used to arrange the stainless steel inner lining plate of the ring structure onto the inner wall of the water supply pipe.

[0010] Preferably, the rolling mechanism includes a plurality of first cylinders and an upper rolling roller. The plurality of first cylinders are fixedly connected inside the vehicle. A mounting frame is fixedly connected to the upper end of the plurality of first cylinders. A lower rolling roller is rotatably connected to the mounting frame. The upper rolling roller is rotatably connected inside the vehicle and is located directly above the lower rolling roller. A driving device is provided between the upper rolling roller and the lower rolling roller. A pushing mechanism is provided on the upper rolling roller. The inner lining mechanism is provided at one end of the upper rolling roller.

[0011] Preferably, the pushing mechanism includes a second cylinder, which is fixedly connected inside the vehicle. One end of the second cylinder is fixedly connected to a push plate, and the lower end of the push plate has a notch, through which the upper rolling roller passes.

[0012] Preferably, the lining mechanism includes a first electric telescopic rod, which is fixedly connected to one end of the upper rolling roller. A connecting block is fixedly connected to one end of the first electric telescopic rod, and a spreading mechanism is provided on the connecting block.

[0013] Preferably, the spreading mechanism includes a plurality of third cylinders, which are circumferentially and uniformly fixedly connected to the side wall of the connecting block, and each of the plurality of third cylinders has a support plate fixedly connected to one end.

[0014] Preferably, a rolling seam welding mechanism is fixedly connected to the lower end of the connecting block. The rolling seam welding mechanism includes a second electric telescopic rod, which is fixedly connected to the lower end of the connecting block. A first welding machine is fixedly connected to one end of the second electric telescopic rod.

[0015] Preferably, one end of the connecting block is provided with a welding edge mechanism, and the welding edge mechanism is connected to the first welding machine. The welding edge mechanism includes a connecting rod, which is fixedly connected to one end of the connecting block. A circular plate is fixedly connected to one end of the connecting rod. A ring-shaped gear is rotatably connected to the side of the circular plate near the connecting block through a rotating mechanism. A second welding machine is fixedly connected to the side wall of the ring-shaped gear.

[0016] Preferably, the rotating mechanism includes a fixed block, a rack and a through-hole. The fixed block is fixedly connected to the connecting rod. A first gear is rotatably connected to the lower end of the fixed block. A second gear is fixedly connected to the lower end of the first gear, and the second gear meshes with the annular surface gear. One end of the rack is fixedly connected to one side of the first welding machine, and the rack meshes with the first gear. The through-hole is opened through the circular plate, and the other end of the rack passes through the through-hole.

[0017] The urban water supply pipeline repair robot proposed in this invention has the following advantages:

[0018] 1. This urban water supply pipeline repair robot, through the setup of a rolling mechanism and an inner lining mechanism, can easily roll a stainless steel inner lining plate into a circular shape. Furthermore, the inner lining mechanism allows for convenient placement of the circular stainless steel inner lining plate onto the inner wall of the water supply pipeline. By lining the inner wall of the water supply pipeline with a circular stainless steel inner lining plate, not only can the corroded parts of the pipeline's inner wall be sealed and covered, preventing further corrosion, but also a layer of stainless steel is effectively formed on the inner wall of the water supply pipeline. The steel layer significantly improves the corrosion resistance of water supply pipelines during water transportation. It also prevents the formation of scale and nodules, ensuring the cleanliness of the pipeline's interior. Furthermore, the stainless steel lining provides excellent self-lubrication, resulting in a smooth inner wall, low flow resistance, and improved transportation efficiency. The stainless steel lining also enhances the pipeline's internal structure's resistance to damage and facilitates maintenance of the annular stainless steel lining plate. Therefore, by lining the inner wall of the water supply pipeline with an annular stainless steel lining plate, corroded areas can be effectively repaired, ensuring normal water transportation.

[0019] 2. The opening mechanism not only facilitates the lifting and support of the pushed-in annular stainless steel liner, making it easier to insert the annular stainless steel liner into the water supply pipe and thus cover the corroded parts on the inner wall of the water supply pipe, but also, by adjusting several third cylinders, several support plates can firmly adhere the annular stainless steel liner to the inner wall of the water supply pipe, thereby enhancing the sealing performance of the annular stainless steel liner over the corroded parts and improving the repair quality of the water supply pipe.

[0020] 3. The rolling seam welding mechanism not only facilitates the welding of the seam created during the rolling process of the annular stainless steel liner, ensuring that the annular stainless steel liner can be completely fitted onto the inner wall of the water supply pipe and preventing any uncovered areas, thus providing comprehensive anti-corrosion treatment for the inner wall of the water supply pipe; but also ensures that the rolling seam is welded to the inner wall of the water supply pipe, enhancing the stability of the annular stainless steel liner on the inner wall of the water supply pipe.

[0021] 4. The welding mechanism allows for easy welding of the entire circular side of the end of the annular stainless steel liner to the inner wall of the water supply pipe. This not only improves the stability of the annular stainless steel liner on the inner wall of the water supply pipe, but also ensures that the annular stainless steel liner is precisely positioned to always cover the corroded parts of the inner wall of the water supply pipe, thereby ensuring the repair effect of the water supply pipe.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1

[0039] Reference Figures 1-4A city water supply pipeline repair robot includes a vehicle 1, a feeding port 2 on one side of the vehicle 1, and a rolling mechanism 5 inside the vehicle 1. The rolling mechanism 5 is used to roll and press a stainless steel inner lining plate 3 into a ring structure. The vehicle 1 can be easily moved to the water supply pipeline that needs to be repaired. The feeding port 2 on the vehicle 1 is used to feed the stainless steel inner lining plate 3 to the rolling mechanism 5. The vehicle 1 has a built-in power supply to power the electrical equipment on the vehicle 1.

[0040] A lining mechanism 6 is provided on one side of the rolling mechanism 5, and the lining mechanism 6 is located on the side of the vehicle 1. The lining mechanism 6 is used to line the stainless steel lining plate 3 of the ring structure onto the inner wall of the water supply pipe 4.

[0041] The rolling mechanism 5 includes several first cylinders 51 and an upper rolling roller 54. The several first cylinders 51 are fixedly connected inside the vehicle 1. The upper ends of the several first cylinders 51 are fixedly connected to a mounting frame 52. A lower rolling roller 53 is rotatably connected to the mounting frame 52. The upper rolling roller 54 is rotatably connected inside the vehicle 1 and is located directly above the lower rolling roller 53. A driving device 55 is provided between the upper rolling roller 54 and the lower rolling roller 53. A pushing mechanism is provided on the upper rolling roller 54. The pushing mechanism includes a second cylinder 56. The second cylinder 56 is fixedly connected inside the vehicle 1. A push plate 57 is fixedly connected to one end of the second cylinder 56. A notch 58 is opened at the lower end of the push plate 57, and the upper rolling roller 54 passes through the notch 58. The notch 58 has an arc-shaped structure, so that the upper rolling roller 54 can be just stuck in the notch 58.

[0042] The inner lining mechanism 6 is located at one end of the upper winding roller 54.

[0043] During the work, firstly, the carrier 1 is moved to the water supply pipe 4 that needs to be repaired, so that the discharge port on one side of the carrier 1 is aligned with the pipe opening of the water supply pipe 4. Then, the workers pass the flat stainless steel inner lining plate 3 through the feed port 2 and transport it between the lower rolling roller 53 and the upper rolling roller 54.

[0044] Next, by adjusting several first cylinders 51, the height of the lower rolling roller 53 is adjusted so that the lower rolling roller 53 moves upward and approaches the upper rolling roller 54 so that the distance between the two is just enough to roll the stainless steel inner liner 3. Then, by starting the drive device 55, the drive device 55 will drive the lower rolling roller 53 and the upper rolling roller 54 to rotate in opposite directions. Then, the lower rolling roller 53 and the upper rolling roller 54 will roll and press the stainless steel inner liner 3 between them, and a circular stainless steel inner liner 3 will be rolled and formed on the upper rolling roller 54.

[0045] After the rolling is completed, several first cylinders 51 are adjusted again to lower the lower rolling roller 53 to the initial position. At this time, the annular stainless steel inner lining plate 3 on the upper rolling roller 54 will naturally fall and fit onto the upper rolling roller 54. Then, by adjusting the second cylinder 56, the push plate 57 is driven to move in a straight line in the horizontal direction. The push plate 57 will push the annular stainless steel inner lining plate 3 towards the inner lining mechanism 6. Then, through the inner lining mechanism 6, the annular stainless steel inner lining plate 3 can be placed on the inner wall of the water supply pipe 4, thus completing the repair process on the inner wall of the water supply pipe 4.

[0046] Therefore, through the arrangement of the rolling mechanism 5 and the lining mechanism 6, the stainless steel lining plate 3 can be easily rolled into a ring shape under the action of the rolling mechanism 5. Furthermore, the ring-shaped stainless steel lining plate 3 can be easily placed onto the inner wall of the water supply pipe 4 via the lining mechanism 6. By lining the inner wall of the water supply pipe 4 with the ring-shaped stainless steel lining plate 3, not only can the corroded parts on the inner wall of the water supply pipe 4 be sealed and covered, thus preventing further corrosion of the inner wall of the water supply pipe 4, but also a layer of stainless steel is added to the inner wall of the water supply pipe 4. This significantly improves the corrosion resistance of the water supply pipe 4 during water transportation; it also prevents the formation of scale and nodules, ensuring the cleanliness of the pipe's interior. Furthermore, the stainless steel lining provides excellent self-lubrication during water transportation, resulting in a smooth inner wall, low flow resistance, and improved efficiency. The stainless steel lining also enhances the pipe's internal structure's resistance to damage and facilitates maintenance of the annular stainless steel lining plate 3. Therefore, by lining the inner wall of the water supply pipe 4 with an annular stainless steel lining plate 3, corroded sections can be effectively repaired, ensuring normal water transportation.

[0047] Example 2

[0048] Reference Figures 2-3 and Figures 5-7 As another preferred embodiment of the present invention, the difference from embodiment 1 is that the inner lining mechanism 6 includes a first electric telescopic rod 61, which is fixedly connected to one end of the upper rolling roller 54. The first electric telescopic rod 61 is connected to the built-in power supply on the vehicle 1 through a wire, and a switch for controlling the operation of the first electric telescopic rod 61 is provided on the wire.

[0049] One end of the first electric telescopic rod 61 is fixedly connected to a connecting block 62. The connecting block 62 is provided with a spreading mechanism 63. The spreading mechanism 63 includes several third cylinders 631. The several third cylinders 631 are circumferentially and uniformly fixedly connected to the side wall of the connecting block 62. One end of each of the several third cylinders 631 is fixedly connected to a support plate 632. The support plates 632 are all arc-shaped structures. The several support plates 632 can form a circle.

[0050] When the pusher plate 57 pushes the annular stainless steel inner lining plate 3 towards the inner lining mechanism 6, it pushes the annular stainless steel inner lining plate 3 to the outside of several support plates 632. Then, by adjusting several third cylinders 631, several support plates 632 are driven to move outward until they just support the inner wall of the annular stainless steel inner lining plate 3. Next, by adjusting the first electric telescopic rod 61, the connecting block 62 is driven to move horizontally to one side. The connecting block 62 will then drive several third cylinders 631 and several... When the support plate 632 moves horizontally to one side, the support plates 632 will drive the annular stainless steel inner lining plate 3 to move horizontally to one side until the annular stainless steel inner lining plate 3 moves and inserts into the water supply pipe 4, so that the annular stainless steel inner lining plate 3 completely covers the corroded part on the inner wall of the water supply pipe 4. Then, the third cylinders 631 are adjusted to make the support plates 632 firmly stick the annular stainless steel inner lining plate 3 to the inner wall of the water supply pipe 4.

[0051] Therefore, by setting up the spreading mechanism 63, not only can the pushed-in annular stainless steel liner 3 be easily supported and supported, facilitating the insertion of the annular stainless steel liner 3 into the water supply pipe 4, thus allowing the annular stainless steel liner 3 to easily cover the corroded parts on the inner wall of the water supply pipe 4; moreover, by adjusting several third cylinders 631 respectively, several support plates 632 can also make the annular stainless steel liner 3 firmly adhere to the inner wall of the water supply pipe 4, thereby enhancing the sealing performance of the annular stainless steel liner 3 in covering the corroded parts and improving the repair quality of the water supply pipe 4.

[0052] Example 3

[0053] Reference Figures 5-7As another preferred embodiment of the present invention, the difference from embodiment 2 is that a rolling seam welding mechanism 64 is fixedly connected to the lower end of the connecting block 62. The rolling seam welding mechanism 64 includes a second electric telescopic rod 641, which is fixedly connected to the lower end of the connecting block 62. The second electric telescopic rod 641 is connected to the built-in power supply on the vehicle 1 through a wire, and a switch for controlling the operation of the second electric telescopic rod 641 is provided on the wire. A first welding machine 642 is fixedly connected to one end of the second electric telescopic rod 641.

[0054] When the annular stainless steel liner 3 is moved and inserted into the water supply pipe 4 to cover the corroded part, the second electric telescopic rod 641 is activated. The second electric telescopic rod 641 will drive the first welding machine 642 to move horizontally in a straight line. During this process, the first welding machine 642 will weld the gap generated during the rolling process of the annular stainless steel liner 3. At the same time, this rolling seam can be welded to the inner wall of the water supply pipe 4, which will enhance the stability of the annular stainless steel liner 3 on the inner wall of the water supply pipe 4.

[0055] Therefore, by setting up the rolling seam welding mechanism 64, not only can the gap generated during the rolling process of the annular stainless steel inner lining plate 3 be easily welded, so that the annular stainless steel inner lining plate 3 can be completely lined to the inner wall of the water supply pipe 4, preventing any uncovered parts and providing comprehensive anti-corrosion treatment for the inner wall of the water supply pipe 4; but also, this rolling seam can be welded to the inner wall of the water supply pipe 4, enhancing the stability of the annular stainless steel inner lining plate 3 on the inner wall of the water supply pipe 4.

[0056] Example 4

[0057] Reference Figures 8-10 As another preferred embodiment of the present invention, the difference from embodiment 3 is that a welding edge mechanism 65 is provided at one end of the connecting block 62, and the welding edge mechanism 65 is connected to the first welding machine 642. The welding edge mechanism 65 includes a connecting rod 651, which is fixedly connected to one end of the connecting block 62. A circular plate 652 is fixedly connected to one end of the connecting rod 651. A ring-shaped gear 659 is rotatably connected to the side of the circular plate 652 near the connecting block 62 through a rotating mechanism. The rotating mechanism includes a fixed block 654 and a spur rack 657. The through-hole 658 and the fixing block 654 are fixedly connected to the connecting rod 651. The lower end of the fixing block 654 is rotatably connected to the first gear 655. The lower end of the first gear 655 is fixedly connected to the second gear 656, and the second gear 656 meshes with the ring surface gear 659. One end of the rack 657 is fixedly connected to one side of the first welding machine 642, and the rack 657 meshes with the first gear 655. The through-hole 658 is opened through the circular plate 652, and the other end of the rack 657 passes through the through-hole 658.

[0058] A second welding machine 653 is fixedly connected to the side wall of the annular gear 659.

[0059] During the horizontal linear motion of the first welding machine 642 driven by the second electric telescopic rod 641, the first welding machine 642 also drives the rack 657 to move horizontally. The rack 657 drives the first gear 655 to rotate, the first gear 655 drives the second gear 656 to rotate, the second gear 656 drives the annular gear 659 to rotate on one side of the circular plate 652, and the annular gear 659 drives the second welding machine 653 to rotate circumferentially. Thus, the second welding machine 653 welds the entire circular side of the end of the annular stainless steel inner lining plate 3, thereby welding this part to the inner wall of the water supply pipe 4.

[0060] Therefore, by setting the welding edge mechanism 65, the entire circular side of the end of the annular stainless steel inner lining plate 3 can be easily welded to the inner wall of the water supply pipe 4. This not only improves the stability of the annular stainless steel inner lining plate 3 on the inner wall of the water supply pipe 4, but also ensures that the annular stainless steel inner lining plate 3 can be accurately positioned to always cover the corroded part of the inner wall of the water supply pipe 4, thereby ensuring the repair effect of the water supply pipe 4.

[0061] Working principle:

[0062] During the work, firstly, the carrier 1 is moved to the water supply pipe 4 that needs to be repaired, so that the discharge port on one side of the carrier 1 is aligned with the pipe opening of the water supply pipe 4. Then, the workers pass the flat stainless steel inner lining plate 3 through the feed port 2 and transport it between the lower rolling roller 53 and the upper rolling roller 54.

[0063] Next, by adjusting several first cylinders 51, the height of the lower rolling roller 53 is adjusted so that the lower rolling roller 53 moves upward and approaches the upper rolling roller 54 so that the distance between the two is just enough to roll the stainless steel inner liner 3. Then, by starting the drive device 55, the drive device 55 will drive the lower rolling roller 53 and the upper rolling roller 54 to rotate in opposite directions. Then, the lower rolling roller 53 and the upper rolling roller 54 will roll and press the stainless steel inner liner 3 between them, and a circular stainless steel inner liner 3 will be rolled and formed on the upper rolling roller 54.

[0064] After the rolling is completed, several first cylinders 51 are adjusted again to make the lower rolling roller 53 descend to the initial position. At this time, the annular stainless steel inner lining plate 3 on the upper rolling roller 54 will naturally fall and fit onto the upper rolling roller 54. Then, by adjusting the second cylinder 56, the push plate 57 is driven to make a linear movement in the horizontal direction. The push plate 57 will push the annular stainless steel inner lining plate 3 towards the inner lining mechanism 6. Then, through the inner lining mechanism 6, the annular stainless steel inner lining plate 3 can be placed on the inner wall of the water supply pipe 4, thus completing the repair process on the inner wall of the water supply pipe 4.

[0065] Secondly, when the pusher plate 57 pushes the annular stainless steel inner lining plate 3 towards the inner lining mechanism 6, it pushes the annular stainless steel inner lining plate 3 to the outside of several support plates 632. Then, by adjusting several third cylinders 631 respectively, several support plates 632 are driven to move outward until several support plates 632 just support the inner wall of the annular stainless steel inner lining plate 3. Then, by adjusting the first electric telescopic rod 61, the connecting block 62 is driven to move horizontally to one side. The connecting block 62 will then drive several third cylinders 631 and several If one of the support plates 632 moves horizontally to one side, then the support plates 632 will drive the circular stainless steel inner lining plate 3 to move horizontally to one side until the circular stainless steel inner lining plate 3 moves and inserts into the water supply pipe 4, so that the circular stainless steel inner lining plate 3 completely covers the corroded part on the inner wall of the water supply pipe 4; then, the third cylinders 631 are adjusted to make the support plates 632 firmly stick the circular stainless steel inner lining plate 3 to the inner wall of the water supply pipe 4.

[0066] Next, when the annular stainless steel inner lining plate 3 is moved and inserted into the water supply pipe 4 to cover the corroded part, the second electric telescopic rod 641 is activated. The second electric telescopic rod 641 will drive the first welding machine 642 to move horizontally in a straight line. In this process, the first welding machine 642 will weld the gap generated during the rolling process of the annular stainless steel inner lining plate 3. At the same time, this rolling seam can be welded to the inner wall of the water supply pipe 4, which will enhance the stability of the annular stainless steel inner lining plate 3 on the inner wall of the water supply pipe 4.

[0067] Then, during the process of the second electric telescopic rod 641 driving the first welding machine 642 to move horizontally in a straight line, the first welding machine 642 will also drive the rack 657 to move horizontally in a straight line. The rack 657 will drive the first gear 655 to rotate, the first gear 655 will drive the second gear 656 to rotate, the second gear 656 will drive the annular surface gear 659 to rotate on one side of the circular plate 652, and the annular surface gear 659 will drive the second welding machine 653 to rotate circumferentially. Then, the second welding machine 653 will weld the entire circular side of the end of the annular stainless steel inner lining plate 3, thus welding this part to the inner wall of the water supply pipe 4.

[0068] Finally, after the annular stainless steel inner lining plate 3 is inserted into the water supply pipe 4 to cover the corroded part and is welded and fixed, several third cylinders 631, second electric telescopic rods 641 and first electric telescopic rods 61 can be adjusted to return them to their initial positions.

[0069] Therefore, based on the above, firstly, through the arrangement of the rolling mechanism 5 and the lining mechanism 6, the stainless steel lining plate 3 can be easily rolled into a ring shape under the action of the rolling mechanism 5. Furthermore, through the lining mechanism 6, the ring-shaped stainless steel lining plate 3 can be easily arranged on the inner wall of the water supply pipe 4. Thus, by lining the inner wall of the water supply pipe 4 with the ring-shaped stainless steel lining plate 3, not only can the corroded parts on the inner wall of the water supply pipe 4 be sealed and covered, thus preventing further corrosion of the inner wall of the water supply pipe 4, but also, by lining the inner wall of the water supply pipe 4 with a layer of... The stainless steel lining significantly improves the corrosion resistance of the water supply pipe 4 during water transport. Furthermore, it prevents the formation of scale and nodules, ensuring the cleanliness of the pipe's interior. The stainless steel lining also provides excellent self-lubrication, resulting in a smooth inner wall, low flow resistance, and improved transport efficiency. Additionally, the stainless steel lining enhances the pipe's internal structural resistance and facilitates maintenance of the annular stainless steel lining plate 3. Therefore, by lining the inner wall of the water supply pipe 4 with an annular stainless steel lining plate 3, corroded sections can be effectively repaired, ensuring normal water transport. Secondly, the supporting mechanism 63 not only facilitates the lifting and support of the pushed-in annular stainless steel liner 3, making it easier to insert the annular stainless steel liner 3 into the water supply pipe 4, thus allowing the annular stainless steel liner 3 to easily cover the corroded parts on the inner wall of the water supply pipe 4; but also, by adjusting several third cylinders 631, several support plates 632 can make the annular stainless steel liner 3 firmly adhere to the inner wall of the water supply pipe 4, thereby enhancing the sealing performance of the annular stainless steel liner 3 in covering the corroded parts and improving the repair quality of the water supply pipe 4. In addition, the rolling seam welding mechanism 64 not only facilitates the welding of the gap generated during the rolling process of the annular stainless steel inner lining plate 3, thus ensuring that the annular stainless steel inner lining plate 3 can be completely lined to the inner wall of the water supply pipe 4, preventing any uncovered parts and providing comprehensive anti-corrosion treatment for the inner wall of the water supply pipe 4; but also enables the rolling seam to be welded to the inner wall of the water supply pipe 4, enhancing the stability of the annular stainless steel inner lining plate 3 on the inner wall of the water supply pipe 4.Meanwhile, the welding mechanism 65 allows for easy welding of the entire circular side of the end of the annular stainless steel liner 3 to the inner wall of the water supply pipe 4. This not only improves the stability of the annular stainless steel liner 3 on the inner wall of the water supply pipe 4, but also ensures that the annular stainless steel liner 3 is precisely positioned to always cover the corroded parts of the inner wall of the water supply pipe 4, thereby ensuring the repair effect of the water supply pipe 4.
