Description

Technical Field

[0001] This invention relates to the field of corrugated pipe technology, specifically to a dual-channel switching double-wall corrugated pipe. Background Technology

[0002] Double-wall corrugated pipes have been widely adopted and applied in many industries due to their excellent performance and relatively economical cost. Traditional double-wall corrugated pipes have only one channel inside, which can only be used to transport or discharge a single medium, and have certain limitations. In recent years, double-channel and even multi-channel double-wall corrugated pipes have appeared on the market, which have a uniform corrugated outer wall and are divided into two or more independent channels inside.

[0003] In practical applications, double-channel double-wall corrugated pipes are also used for water flow transmission. Some water flows need to be filtered, so a filter screen is often installed inside the double-wall corrugated pipe for filtration. However, over time, the filter screen will accumulate more and more impurities. Therefore, it is necessary to stop the water flow transmission first and then clean the filter screen. This undoubtedly makes continuous operation impossible. Summary of the Invention

[0014] (III) Beneficial Effects

[0015] This invention provides a dual-channel switching double-wall corrugated pipe. It has the following beneficial effects:

[0016] 1. This invention transmits water through a first connecting pipe and an upper water flow channel. The water is filtered by an arc-shaped water flow filter. When the arc-shaped water flow filter contains a large amount of impurities, a servo motor is activated. The output shaft of the servo motor rotates a rotating gear, causing a fixed gear ring to rotate a switching movable pipe, thus swapping the positions of the first and second connecting pipes. At this point, water is transmitted through the first connecting pipe and the lower water flow channel. Then, the second connecting pipe is connected to a backwash pipe. The backwash water is transmitted from the right side of the second connecting pipe to the left side to backwash the arc-shaped water flow filter. The backwashed water is discharged through the left side of the second connecting pipe. This not only ensures uninterrupted water flow transmission but also simultaneously cleans the arc-shaped water flow filter, guaranteeing continuous and efficient operation.

[0017] 2. In this invention, the fixed connecting plate and the mounting clip are interference-fitted, which allows the arc-shaped water flow filter screen to be disassembled and replaced. Attached Figure Description

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.

[0026] Example:

[0027] like Figure 1-6 As shown, this embodiment of the invention provides a dual-channel switching double-wall corrugated pipe, including a corrugated pipe body 1. A first connecting partition 2 is fixedly connected to the inner wall of the corrugated pipe body 1. The first connecting partition 2 divides the interior of the corrugated pipe body 1 into two symmetrically arranged water flow channels 3. Two arc-shaped water flow filters 4 are detachably connected to the interior of the corrugated pipe body 1. A fixed connecting plate 5 is fixedly connected to the inner wall of the corrugated pipe body 1. An installation block 6 is fixedly connected to one side of the arc-shaped water flow filters 4. The fixed connecting plate 5 and the installation block 6 are engaged. The fixed connecting plate 5 and the installation block 6 are interference-fitted. This arrangement allows the arc-shaped water flow filters 4 to be disassembled and replaced.

[0028] Two arc-shaped water flow filter screens 4 are located inside two water flow channels 3 respectively. Both ends of the corrugated pipe body 1 are fixedly connected to end connecting rings 7. The end of the end connecting ring 7 away from the corrugated pipe body 1 is rotatably sealed to a switching movable pipe 8. The surface of the end connecting ring 7 is provided with a power component that drives the switching movable pipe 8 to rotate. The power component includes a servo motor 10 fixedly connected to the outer surface of the end connecting ring 7. The output shaft of the servo motor 10 is fixedly connected to a rotating gear 11. The outer surface of the switching movable pipe 8 is fixedly connected to a fixed gear ring 9. The rotating gear 11 meshes with the fixed gear ring 9. When the servo motor 10 is started, the output shaft of the servo motor 10 rotates the rotating gear 11, causing the fixed gear ring 9 to rotate the switching movable pipe 8, thereby swapping the positions of the first connecting pipe 17 and the second connecting pipe 18.

[0029] A second connecting baffle 12 is fixedly connected to the inner wall of the switching movable pipe 8. Each of the two switching movable pipes 8 has a detachable pipe assembly at the end furthest from the end connecting ring 7. The detachable pipe assembly includes a threaded connecting end cap 16 threadedly connected to the switching movable pipe 8. A first connecting pipe 17 and a second connecting pipe 18 are fixedly connected through the side wall of the threaded connecting end cap 16. Valves are installed on both the first connecting pipe 17 and the second connecting pipe 18. The first connecting pipe 17 is located above the second connecting pipe 18. The two first connecting pipes 17 correspond to the upper water flow channel 3, and the two second connecting pipes 18 correspond to the lower water flow channel 3. Water is transmitted through the first connecting pipes 17 and the lower water flow channel 3. Then, the second connecting pipe 18 is connected to the backwash pipe. The backwash water is transmitted from the right second connecting pipe 18 to the left second connecting pipe 18 to backwash the arc-shaped water flow filter screen 4. The backwashed water is discharged through the left second connecting pipe 18, ensuring uninterrupted water flow transmission. It can also clean the arc-shaped water flow filter screen 4 at the same time, ensuring the continuity and efficiency of the operation. The inner wall of the switching movable pipe 8 is fixedly connected with an internal mounting ring 14, and the side wall of the internal mounting ring 14 is fixedly connected with a sealing gasket 15. The threaded connection end cap 16 is in contact with the sealing gasket 15. One side of the second connecting partition 12 is tightly in contact with the threaded connection end cap 16. The sealing gasket 15 ensures the sealing between the threaded connection end cap 16 and the switching movable pipe 8. The other side of the second connecting partition 12 is fixedly connected with a rubber bonding strip 13. The rubber bonding strip 13 ensures the sealing between the first connecting partition 2 and the second connecting partition 12. The rubber bonding strip 13 is in contact with one side of the first connecting partition 2. The outer surface of the end connecting ring 7 is fixedly connected with a connecting mounting seat 19. Both sides of the connecting mounting seat 19 are fixedly connected with connecting blocks 20. The surface of the connecting block 20 is provided with a through mounting hole, which can be used to install bolts. The connecting mounting seat 19 can be used to fix the end connecting ring 7.

[0030] Working principle:

[0031] During normal water flow transmission, the two first connecting pipes 17 are connected to external water flow pipes, and water flow is transmitted through the first connecting pipes 17 and the upper water flow channel 3. The water flow is filtered through the arc-shaped water flow filter screen 4. When there are many impurities in the arc-shaped water flow filter screen 4, the servo motor 10 is started. The output shaft of the servo motor 10 drives the rotating gear 11 to rotate, which causes the fixed gear ring 9 to rotate with the switching movable pipe 8, so that the positions of the first connecting pipe 17 and the second connecting pipe 18 are switched. At this time, water flow is transmitted through the first connecting pipe 17 and the lower water flow channel 3. Then, the second connecting pipe 18 is connected to the backwash pipe. The flushing water is transmitted from the second connecting pipe 18 on the right to the second connecting pipe 18 on the left to backwash the arc-shaped water flow filter screen 4. The flushed water is discharged through the second connecting pipe 18 on the left. This not only ensures that the water flow can be transmitted without stopping, but also cleans the arc-shaped water flow filter screen 4 at the same time, ensuring the continuity and efficiency of the operation.
