[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] A novel MPVE blended double-wall corrugated pipe, such as Figures 1-6 As shown, the system includes a pipe 1 with a cavity 2. A sound-insulating cotton 3 is fixedly connected to the cavity 2 near the outer wall of the pipe 1. Several sound-absorbing cotton 4s are fixedly connected to the sound-insulating cotton 3 near the inner wall of the pipe 1. A cleaning assembly for cleaning the inner wall of the pipe 1 is provided on the inner wall of the pipe 1. The cleaning assembly includes sliding blocks 5 slidably connected to both sides of the inner wall, a positioning rod 6 rotatably connected to the two sliding blocks 5 on one side close to each other, and a scraper 7 fixedly connected between the two positioning rods 6. Torsion springs 8 are fixedly connected to the two sliding blocks 5. The other ends of the two torsion springs 8 are fixedly connected to both sides of the scraper 7 respectively. The torsion springs 8 are sleeved on the positioning rods 6. The pipe 1 and the scraper 7 are provided with driving components for driving the scraper 7 to contact the inner wall of the pipe 1. The driving components include a baffle 9 slidably connected to the inner wall of the pipe 1 and an L-shaped baffle 10 fixedly connected to the scraper 7.

[0025] like Figures 1-6 As shown, after the corrugated pipe is buried underground, when the water flow is small, debris in the water will adhere to the pipe 1. When the water flow is large, the water will impact the baffle 9. Under the impact of the water flow, the baffle 9 will begin to move, and then the baffle 9 will push the L-shaped stop bar 10. When the L-shaped stop bar 10 is pushed by the baffle 9, the scraper bar 7 will rotate. At this time, the torsion spring 8 is in a deformed state. Finally, under the push of the baffle 9, the scraper bar 7 will be aligned and contact the inner wall of the pipe 1. When the L-shaped stop bar 10 is aligned, the baffle 9 will be in an L-shaped position. At the angle of the baffle 10, the baffle 9 continues to be pushed by the water flow, which will drive the sliding block 5, the positioning rod 6 and the aligning scraper 7 to move. When the aligning scraper 7 moves, it will remove the debris adhering to the inner wall of the pipe 1 to avoid turbulence and vortex in the water flow inside the pipe 1, which would increase noise. Subsequently, a small amount of noise will pass through the inner wall of the pipe 1 and come into contact with the sound-absorbing cotton 4 and be partially absorbed. The noise that passes through the sound-absorbing cotton 4 will be blocked by the sound insulation cotton 3, thereby reducing the noise generated by drainage inside the corrugated pipe.

[0026] like Figures 1-3As shown, a guide plate 11 is fixedly connected to the side of the baffle 9 away from the sliding block 5. The guide plate 11 can prevent debris from being accidentally caught on the baffle 9, which would make it difficult for the baffle 9 to move.

[0027] like Figures 1-6 As shown, two automatic rope winders 12 are fixedly connected to the inner wall of pipe 1. The rope of the automatic rope winder 12 is fixedly connected to the adjacent sliding block 5. A cleaning block 13 is fixedly connected to the inner wall of pipe 1. The cleaning block 13 has a through hole 14 for the rope of the automatic rope winder 12 to pass through. When the baffle 9 is impacted by the water flow and the scraper 7 removes the debris adhering to the inner wall of pipe 1, the rope in the automatic rope winder 12 will move with the sliding block 5 and be pulled out from the automatic rope winder 12. At this time, the coil spring in the automatic rope winder 12 is in a contracted state. As the water flow decreases, the torsion spring 8 and the coil spring in the automatic rope winder 12 begin to reset. The reset of the torsion spring 8 will drive the scraper 7 to reset. At this time, the scraper 7 no longer contacts the inner wall of the pipe 1, preventing the scraper 7 from always being in a straight position, which would cause the scraper 7 to block debris in the water flow and leave debris behind. The spring in the automatic rope winder 12 resets, allowing the automatic rope winder 12 to start winding the pull rope inside the automatic rope winder 12. When the pull rope in the automatic rope winder 12 starts winding, the sliding block 5 will move synchronously to reset. When the sliding block 5 moves to reset, it will drive the scraper 7 and the L-shaped stop bar 10 to reset. When the L-shaped stop bar 10 resets, it will push the baffle 9, causing the baffle 9 to also reset. In this way, the inner wall of the pipe 1 can be cleaned again when a large water flow occurs next time.

[0028] like Figures 1-6 As shown, a guide block 15 is fixedly connected to the sliding block 5, which can protect the torsion spring 8 and prevent impurities from adhering to the torsion spring 8, causing the torsion spring 8 to malfunction.

[0029] like Figures 2-4 As shown, several support rings 16 are fixedly connected inside the cavity 2, which can improve the strength of the bellows structure.

[0030] Working principle: after the corrugated pipe is buried in the ground, when the water flow is small, the impurities in the water flow will adhere to the pipe 1, when the water flow is large, the water flow will impact the baffle 9, under the impact of the water flow, the baffle 9 will start to move, then the baffle 9 will push the L-shaped blocking rod 10, when the L-shaped blocking rod 10 is pushed by the baffle 9, the scraper 7 will rotate, at this time the torsional spring 8 is in a deformed state, finally under the pushing of the baffle 9, the scraper 7 is righted to contact the inner wall of the pipe 1, when the L-shaped blocking rod 10 is righted, the baffle 9 will be at the included angle of the L-shaped blocking rod 10, at this time the baffle 9 continues to be pushed by the water flow and will drive the sliding block 5, the positioning rod 6 and the righted scraper 7 to move, when the righted scraper 7 moves, it will remove the impurities adhered to the inner wall of the pipe 1, so as to avoid the turbulence and vortex of the water flow in the pipe 1, increase the noise, then a small amount of noise will pass through the inner wall of the pipe 1 and contact the sound-absorbing cotton 4 to be absorbed part, the part of the noise passing through the sound-absorbing cotton 4 will be interrupted by the sound insulation cotton 3, so that the noise generated in the corrugated pipe due to drainage is reduced.

[0031] When the baffle 9 is impacted by the water flow to drive the scraper 7 to remove the impurities adhered to the inner wall of the pipe 1, the pull rope in the automatic rope winder 12 will be pulled out from the automatic rope winder 12 along with the movement of the sliding block 5, at this time the coil spring in the automatic rope winder 12 is in a retracted state, as the water flow becomes small, the torsional spring 8 and the coil spring in the automatic rope winder 12 start to reset, the reset of the torsional spring 8 drives the scraper 7 to reset, at this time the scraper 7 no longer contacts the inner wall of the pipe 1, avoiding the scraper 7 being always in a righted state, causing the scraper 7 to block the impurities in the water flow, resulting in impurities remaining, the reset of the coil spring in the automatic rope winder 12 can make the automatic rope winder 12 start to wind the pull rope in the automatic rope winder 12, when the pull rope in the automatic rope winder 12 starts to wind, the sliding block 5 will move synchronously to start to reset, when the sliding block 5 moves to reset, it will drive the scraper 7 and the L-shaped blocking rod 10 to reset, when the L-shaped blocking rod 10 resets, the L-shaped blocking rod 10 will push the baffle 9, so that the baffle 9 also starts to reset, so that the inner wall of the pipe 1 can be cleaned again when the next large water flow occurs.

[0032] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as the protection scope of the present application.
