Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example

A first motor 2 is fixedly connected to the middle of the upper side of the outer surface of the support frame 1. A one-way screw 3 is fixedly connected to the output end of the first motor 2. A moving block 4 is slidably connected to the outer surface of the one-way screw 3. A fixing groove 5 is fixedly connected to the lower surface of the moving block 4.
[0028] In this embodiment, a second motor 6 is fixedly connected to one end of the outer surface of the fixing groove 5, and a bidirectional lead screw 7 is fixedly connected to the output end of the second motor 6. One end of the bidirectional lead screw 7 is rotatably connected to the inner wall of the fixing groove 5. A first arc-shaped rust removal plate 8 is slidably connected to one end of the outer surface of the bidirectional lead screw 7, and a second arc-shaped rust removal plate 9 is slidably connected to the other end of the outer surface of the bidirectional lead screw 7.
[0029] In practical use, the water pipe that needs rust removal is sprayed with rust remover, so that the surface of the water pipe is coated with rust remover. Then, the distance is adjusted according to the required length of the water pipe to be rusted. One end of the water pipe is connected to the outer surface of the limiting post 32. The other end is first started by starting the second motor 6 so that the distance between the first arc-shaped rust removal plate 8 and the second arc-shaped rust removal plate 9 on the outer surface of the bidirectional screw 7 is adjusted to reduce the collision of the water pipe when it is fixed in position. After fixing the other end of the water pipe in position, the second motor 6 is started again so that the inside of the first arc-shaped rust removal plate 8 and the second arc-shaped rust removal plate 9 contacts the outer surface of the water pipe. The first motor 2 is started so that the moving block 4 drives the fixing groove 5 and the first arc-shaped rust removal plate 8 and the second arc-shaped rust removal plate 9 to move on the outer surface of the unidirectional screw 3. During the movement, the first arc-shaped rust removal plate 8 and the second arc-shaped rust removal plate 9 rub against the outer surface of the water pipe to remove rust.
[0030] In this embodiment, a third motor 10 is fixedly connected to the center of the front of the support frame 1. A rotating rod 11 is fixedly connected to the output end of the third motor 10. A turntable 12 is rotatably connected to the outer surface of the rotating rod 11. One end of the rotating rod 11 extends through to the inner side of the support frame 1. The outer surface of the turntable 12 is rotatably connected to the interior of the support frame 1. A threaded rod 13 is fixedly connected to one end of the rotating rod 11. A cylinder 14 is fixedly connected to the center of the inner side of the turntable 12. The interior of the cylinder 14 is threadedly connected to the outer surface of the threaded rod 13.
[0031] In practical use, when fixing the other end of the pipe, align the inner diameter of the pipe with the position of the threaded rod 13, and then start the third motor 10 to make the rotating rod 11 rotate, causing the threaded rod 13 to rotate inside the cylinder 14.
[0032] In this embodiment, a limiting disk 15 is fixedly connected to one end of the outer surface of the threaded rod 13. A ring 16 is rotatably connected to the outer surface of the limiting disk 15. A telescopic rod 17 is uniformly fixedly connected to one side of the outer surface of the ring 16. A connecting housing 18 is fixedly connected to one end of the telescopic rod 17. A connecting plate 19 is fixedly connected to the outer surface of the connecting housing 18. The interior of the connecting housing 18 is slidably connected to the outer surface of the cylinder 14. The outer surface of the threaded rod 13 is slidably connected to the interior of the connecting housing 18.
[0033] In practical use, when the threaded rod 13 rotates, the connecting housing 18 slides on the outer surfaces of the threaded rod 13 and the cylinder 14, while the telescopic rod 17 is also adjusting. When the third motor 10 rotates forward, the threaded rod 13 rotates forward, causing the outer surface of the limiting plate 15 at one end of the threaded rod 13 to rotate with the inside of the ring 16. At the same time, the telescopic rod 17 extends, causing the connecting housing 18 to slide on the outer surfaces of the cylinder 14 and the threaded rod 13, gradually approaching one end of the turntable 12, completing the process of opening the L sliding plate 21, so as to clamp and fix the position inside the pipe. When the third motor 10 rotates in reverse, the threaded rod 13 rotates in reverse, causing the outer surface of the limiting plate 15 at one end of the threaded rod 13 to rotate with the inside of the ring 16. At the same time, the telescopic rod 17 retracts, causing the connecting housing 18 to slide on the outer surfaces of the cylinder 14 and the threaded rod 13, gradually approaching one end of the limiting plate 15, completing the process of retracting the L sliding plate 21, so as to loosen the pipe.
[0034] In this embodiment, a connecting rod 20 is rotatably connected to the outer surface of the connecting plate 19, and an L-sliding plate 21 is rotatably connected to one end of the connecting rod 20. One side of the outer surface of the L-sliding plate 21 is slidably connected to the inner wall of the turntable 12.
[0035] In actual use, when the connecting housing 18 moves to a new position, the connecting rod 20 on the outer surface of the connecting plate 19 will also rotate, causing the L sliding plate 21 to move to a new position on the inner wall of the turntable 12, so that the distance between the outer diameter of the L sliding plate 21 and the inner diameter of the water pipe can be adjusted.
[0036] In this embodiment, a connecting block 22 is uniformly and fixedly connected to one side of the turntable 12, and a first gear 23 is fixedly connected to one side of the outer surface of the connecting block 22.
[0037] In practical use, the connecting block 22 supports and fixes the first gear 23 to the turntable 12, so as to allow the clamp on the inner wall of the turntable 12 to rotate.
[0038] In this embodiment, a fourth motor 24 is fixedly connected to the lower part of the front side of the support frame 1. A second gear 25 is fixedly connected to the output end of the fourth motor 24. One end of the second gear 25 is rotatably connected to the front side of the support frame 1. The outer surface of the second gear 25 is meshed with the outer surface of the first gear 23. A buffer frame 26 is fixedly connected to one side of the inner bottom wall of the support frame 1.
[0039] In practical use, after the fourth motor 24 is started, the second gear 25 rotates, which causes the first gear 23 to rotate. This achieves the effect of rotating the pipe to remove rust during the rust removal process. If the water pipe falls during the fixing process, the buffer frame 26 can effectively protect the water pipe and reduce the damage caused by the water pipe falling.
[0040] In this embodiment, a long plate 27 is slidably connected inside the buffer frame 26, a rack 28 is fixedly connected to one side of the outer surface of the long plate 27, a fifth motor 29 is fixedly connected to one side of the upper surface of the buffer frame 26, a third gear 30 is fixedly connected to the output end of the fifth motor 29, and the outer surface of the third gear 30 is meshed with one side of the rack 28.
[0041] In practical use, when the distance needs to be adjusted, the fifth motor 29 is started to make the third gear 30 rotate. The third gear 30 meshes with the rack 28, causing the long plate 27 to move inside the buffer frame 26. When the appropriate position is reached, the fifth motor 29 is stopped. The sliding of the long plate 27 inside the buffer frame 26 can effectively move the position of the limiting post 32.
[0042] In this embodiment, a support plate 31 is fixedly connected to one end of the outer surface of the long plate 27, a limit post 32 is rotatably connected to the inner wall of the support plate 31, and the lower surface of the support plate 31 is slidably connected to the other side of the inner bottom wall of the support frame 1.
[0043] In actual use, when the long plate 27 moves, the support plate 31 also moves on the other side of the inner bottom wall of the support frame 1, and the support plate 31 supports the limiting post 32 and the water pipe.
[0044] Working principle: During use, the water pipe to be derusted is sprayed with rust remover, so that the surface of the water pipe is coated with rust remover. Then, the distance is adjusted according to the required length of the water pipe to be derusted. One end of the water pipe is clamped to the outer surface of the limiting post 32. The other end is first started by activating the second motor 6 to adjust the distance between the first arc-shaped rust removal plate 8 and the second arc-shaped rust removal plate 9 on the outer surface of the double-acting screw 7 to reduce collisions when the water pipe is fixed in position. When fixing the other end of the pipe, the inner diameter of the pipe is aligned with the position of the threaded rod 13. Then, the third motor 10 is started to rotate the rotating rod 11, causing the threaded rod 13 to move inside the cylinder 14. As the threaded rod 13 rotates, the connecting housing 18 slides on the outer surfaces of the threaded rod 13 and the cylinder 14. Simultaneously, the telescopic rod 17 adjusts. When the third motor 10 rotates forward, the threaded rod 13 rotates forward, causing the outer surface of the limiting plate 15 at one end of the threaded rod 13 to rotate with the inside of the ring 16. At the same time, the telescopic rod 17 extends, causing the connecting housing 18 to slide on the outer surfaces of the cylinder 14 and the threaded rod 13, gradually approaching one end of the turntable 12, completing the process of opening the L-shaped sliding plate 21. After the other end of the water pipe is fixed in position, the second motor 6 is started, causing the inside of the first arc-shaped rust-removing plate 8 and the second arc-shaped rust-removing plate 9 to connect with the water pipe. When the outer surface of the pipe comes into contact, the first motor 2 is started, causing the moving block 4 to move the fixed groove 5 and the first arc-shaped rust-removing plate 8 and the second arc-shaped rust-removing plate 9 on the outer surface of the one-way screw 3. During the movement, the first arc-shaped rust-removing plate 8 and the second arc-shaped rust-removing plate 9 rub and remove rust from the outer surface of the water pipe. After the fourth motor 24 is started, the second gear 25 rotates, causing the first gear 23 to rotate, thus achieving the effect of rotating the pipe to remove rust during the rust removal process. When the distance needs to be adjusted, the fifth motor 29 is started, causing the third gear 30 to rotate. The third gear 30 meshes with the rack 28, causing the long plate 27 to move inside the buffer frame 26, adjusting to the desired position. When the fifth motor 29 is stopped at the appropriate position, the long plate 27 slides inside the buffer frame 26, which can drive the limiting post 32 to move effectively. When the long plate 27 moves, the support plate 31 also moves on the other side of the bottom wall of the support frame 1. The support plate 31 supports the limiting post 32 and the water pipe. When the third motor 10 reverses, the threaded rod 13 reverses, causing the outer surface of the limiting plate 15 at one end of the threaded rod 13 to rotate with the inside of the ring 16. At the same time, the telescopic rod 17 retracts, causing the connecting housing 18 to slide on the outer surface of the cylinder 14 and the threaded rod 13, gradually approaching one end of the limiting plate 15, completing the process of retracting the L sliding plate 21, so as to loosen the pipe.
