[0001] The present invention relates to the technical field of drainage pipes, and in particular to an anti-crystallization replaceable filling type drainage pipe. Background Art

[0002] Municipal tunnel drainage systems often face blockage problems caused by mineral crystallization in drainage pipes. This is because calcium and magnesium minerals dissolved in tunnel seepage water enter the tunnel drainage pipes with the water flow. When the water flow is slow or there is air in the pipe section, the water continues to evaporate, causing the mineral concentration to increase. Crystals such as calcium carbonate precipitate and accumulate on the pipe wall, causing blockage and affecting drainage.

[0003] For example, in the prior art, patent document CN215211424U proposes a municipal tunnel drainage device that intercepts strip-shaped impurities (such as plastic bags) through a sewage collection box.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The embodiment of the present invention provides a crystallization-proof replaceable filling type drain pipe, such as Figure 1-16 As shown, the anti-crystallization replaceable filling drainage pipe includes an upstream pipe 101, a downstream pipe 102, and a debris removal box 1 and a water pipe 2 arranged between the upstream pipe 101 and the downstream pipe 102; wherein, the debris removal box 1 is provided with a water inlet and a water outlet on both sides, and a separation mechanism for removing floating garbage is provided in the debris removal box 1; a sponge tube 20 is provided in the water pipe 2 for absorbing water to reduce evaporation and reduce crystallization in the pipe.

[0026] In this embodiment, efficient drainage and crystallization prevention are achieved through the use of a debris removal box 1 and a water pipe 2, located between the upstream pipe 101 and the downstream pipe 102. A separation mechanism is incorporated into the debris removal box 1 to separate and collect floating debris. A hydrophilic polyurethane sponge 20 is embedded in the water pipe 2 to effectively absorb and bind water, reducing the evaporation area and inhibiting the crystallization of minerals such as calcium carbonate.

[0027] In a further preferred embodiment of the present invention, the separation mechanism (such as Figure 1 、 Figure 2 and Figure 16 The utility model comprises: a rotating shaft 13 rotatably mounted on the inner walls on both sides of the debris removal box 1 through a sealed bearing, one end of the rotating shaft 13 extends to the outside of the debris removal box 1; a plurality of rows of rotating gear rods 14 fixedly mounted on the rotating shaft 13, and the plurality of rows of rotating gear rods 14 are distributed in a ring shape; a servo motor 15 fixedly mounted on one side of the debris removal box 1, and the output shaft of the servo motor 15 is fixedly connected to one end of the rotating shaft 13 through a coupling.

[0028] In this embodiment, the separation mechanism drives the rotating shaft 13 through the servo motor 15 to drive the multiple rows of rotating tooth rods 14 distributed in a ring to rotate, forming an offset with the fixed tooth rods 12, separating the floating garbage in the water flow and guiding it to the semi-enclosed space formed by the L-shaped mesh plate 10; the rotating shaft 13 is installed through a sealed bearing to ensure smooth operation and waterproof sealing, and the servo motor 15 cooperates with the flow sensor 7 to realize intelligent start and stop, which not only ensures that impurities are cleaned in time but also avoids idling energy consumption, solves the problem that floating garbage such as plastic bags are easily entangled and blocked in traditional drainage pipes, and improves the reliability of the drainage system.

[0029] In a further preferred embodiment of the present invention, an L-shaped mesh plate 10 and a vertical mesh plate 11 (such as Figure 2 and Figure 15 As shown in FIG, the L-shaped mesh plate 10 and the vertical mesh plate 11 form a semi-open space with the inner wall of the debris removal box 1 for collecting the floating garbage separated by the rotating toothed rod 14, and a row of fixed toothed rods 12 are fixedly installed on the debris removal box 1. The fixed toothed rods 12 are staggered with the rotating toothed rods, and the rotating toothed rods 14 rotate clockwise (in Figure 2 When the upstream pipe 1 is rotated (from a different perspective), the floating garbage in the water transported in the upstream pipe 1 is flipped onto the fixed tooth rod 12 and slides into the above-mentioned semi-open space.

[0030] In this embodiment, the L-shaped mesh plate 10 and the vertical mesh plate 11 cooperate with the inner wall of the debris removal box 1 to form a semi-open collection space. When the servo motor 15 drives the rotating tooth rod 14 to rotate clockwise, the offset setting between it and the fixed tooth rod 12 produces a forced flipping effect, separating the floating garbage in the water and pushing it into the collection space, ensuring the reliability of impurity collection.

[0031] In a further preferred embodiment of the present invention, the top and bottom of the debris removal box 1 are provided with cleaning ports, and an upper sealing cover 16 and a lower sealing cover 17 are detachably installed respectively, and the upper sealing cover 16 and the lower sealing cover 17 are opened to clean floating garbage and deposited garbage respectively.

[0032] In this embodiment, the upper sealing cover 16 provided on the top of the debris removal box 1 facilitates direct cleaning of floating garbage collected by the L-shaped mesh plate 10, and the lower sealing cover 17 provided at the bottom can quickly discharge deposited impurities; combined with the flippable feature of the debris removal box 1, the original top cleaning port is turned downward to dump garbage, thereby improving cleaning efficiency.

[0033] In a further preferred embodiment of the present invention, a filter cover 18 is installed on the water outlet on one side of the impurity removal box 1 to cover the water outlet and prevent deposited impurities from entering the water pipe 2.

[0034] In this embodiment, the filter cover 18 is tightly installed at the water outlet of the debris removal box 1 to form a filter barrier, which can effectively intercept fine sediments while ensuring smooth water flow.

[0035] In a further preferred embodiment of the present invention, the sponge tube 20 in the water pipe 2 is a hydrophilic polyurethane sponge in the shape of a circular tube, which is used to reduce the formation and accumulation of mineral crystals in the water pipe 2.

[0036] In this embodiment, the tubular hydrophilic polyurethane sponge tube 20 converts the free water in the water pipe 2 into bound water through its unique microporous structure, effectively reducing the water evaporation area and inhibiting the crystallization of minerals such as calcium carbonate.

[0037] In a further preferred embodiment of the present invention, a plurality of annularly distributed limiting strips 21 are provided on the inner wall of the water pipe 2, a plurality of limiting slots 22 are opened on the outer wall of the sponge tube 20, and the plurality of limiting strips 21 extend into the plurality of limiting slots 22 respectively.

[0038] In this embodiment, the limiting strips 21 distributed in an annular manner on the inner wall of the water pipe 2 and the limiting grooves 22 on the outer wall of the sponge tube 20 form an axial positioning structure, ensuring that the sponge tube 20 is completely fitted with the tube wall when installed, ensuring the stability of the sponge tube 20. At the same time, when the water pipe 2 is manually rotated and adjusted, the sponge tube 20 can be rotated synchronously with the water pipe 2, so that different parts of the sponge tube 2 are in the lowest water absorption position in turn, so that its utilization rate is maximized; the cooperation between the limiting strips 21 and the limiting grooves 22 not only ensures that it will not loosen during long-term use, but also makes it convenient to pull out the sponge tube 2 longitudinally after removing the water pipe 2, so as to facilitate replacement.

[0039] In a further preferred embodiment of the present invention, the ends of the upstream pipe 101 and the downstream pipe 102 close to each other are fixedly sleeved with a first connecting sleeve 103 and a second connecting sleeve 104, respectively. Connecting pipes 19 are provided on both sides of the debris removal box 1, which are connected to the inside of the debris removal box 1 through the water inlet and the water outlet, respectively. One of the connecting pipes 19 is rotatably sleeved on one end of the first connecting sleeve 103 through a sealed bearing. Telescopic pipes 30 are installed at both ends of the water supply pipe 2. The other connecting pipe 19 is rotatably sleeved on one end of one of the telescopic pipes 30 through a sealed bearing. The second connecting sleeve 104 is rotatably sleeved on one end of the other telescopic pipe 30 through a sealed bearing. The middle section of the telescopic pipe 30 is the telescopic section 31. The debris removal box 1 can be manually flipped over so that the cleaning port on the top is facing downward. Opening the upper sealing cover 16 can easily clean out floating impurities.

[0040] In this embodiment, the first connecting sleeve 103 and the second connecting sleeve 104 form a rotatable pipe connection system with the connecting pipe 19 and the telescopic tube 30 through a sealed bearing, and the telescopic section 31 of the telescopic tube 30 is used to realize free adjustment of the length, so that the impurity removal box 1 can be rotated 360 degrees to the optimal cleaning angle; when cleaning is required, the impurity removal box 1 can be flipped 180 degrees so that the upper sealing cover 16 faces downward, so that the impurities can be quickly dumped and the cleaning work is convenient.

[0041] In a further preferred embodiment of the present invention, the flanges at both ends of the water pipe 2 are fixedly connected to the flange at one end of the telescopic tube 30 by bolts, and the top and bottom of the telescopic tube 30 are fixedly installed with a first fixing block 32, and two symmetrical and horizontally arranged first screw rods 33 are fixedly installed on the flange of the telescopic tube 30. The first screw rod 33 passes through the through hole on the first fixing block 32, and a nut is threaded on the first screw rod 33. After removing the bolts connecting the telescopic tube 30 and the water pipe 2, the telescopic section 31 of the telescopic tube 30 is shortened by tightening the nut on the first screw rod 33, so as to facilitate the removal of the water pipe 2 and then facilitate the replacement of the sponge tube 20.

[0042] In this embodiment, the telescopic tube 30 is connected to the water pipe 2 via flange bolts. Together with the first fixing block 32 and the first screw 33, it forms a quick-adjustment mechanism. When the sponge cartridge 20 needs to be replaced, simply remove the flange bolts and tighten the nut on the first screw 33 to retract the telescopic section 31 by more than 50 mm, instantly freeing up space for the pipe connection. This design simplifies traditional pipe installation and disassembly, which typically requires multiple people, to a single person in just three minutes, improving maintenance efficiency by 90%. The bidirectional symmetrical arrangement of the first screw 33 ensures uniform force distribution, preventing damage to the sealing surface from pipe deflection. Combined with the 360-degree rotatable connecting tube 19 and the debris removal box 1, the entire system allows for quick, tool-free replacement of the sponge cartridge 20 while maintaining a pressure tolerance of 0.5 MPa. This makes it particularly suitable for efficient maintenance in confined spaces such as tunnels, reducing annual maintenance costs by over 60%.

[0043] In a further preferred embodiment of the present invention, a locking mechanism is provided on the first connecting sleeve 103 for locking the connecting pipe 19 and further locking the debris removal box 1. Figure 3 and Figure 7 As shown, the locking mechanism includes a second fixed block 34 fixedly mounted on the first connecting sleeve 103, a sliding sleeve is provided on the second fixed block 34, one end of the sliding rod 35 is fixedly connected to a pin block 36, and the other end is fixedly installed with a pull ring 38, a sliding sleeve is provided on the sliding rod 35 and a spring 37 is provided between the second fixed block 34 and the pin block 36, and a corresponding connecting tube 19 is fixedly provided with a ring block 39, and two pin grooves symmetrically arranged on one side of the ring block 39, and the pin block 36 is snapped into the corresponding pin groove to lock the debris removal box 1.

[0044] In this embodiment, the locking mechanism drives the pin block 36 to engage with the pin groove of the ring block 39 through the sliding rod 35 on the second fixed block 34, and the spring 37 provides a locking force to ensure that the debris removal box 1 does not move; when cleaning is required, it is only necessary to pull down the pull ring 38 with one hand to overcome the elastic force of the spring 37 to release the lock, so that the debris removal box 1 can be freely rotated to the optimal cleaning position; the mechanism adopts a symmetrical double pin groove design, allowing the debris removal box 1 to be quickly locked at two positions of 0° and 180°, realizing a quick cleaning process of "one pull, one turn, and one flip".

[0045] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a flow sensor 7 is installed on the upstream pipe 1 to monitor whether there is liquid flowing in the upstream pipe 1 to trigger the start of the servo motor 15, which is automatically controlled by a set controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. It is an existing mature technology and will not be elaborated here.

[0046] In this embodiment, the flow sensor 7 (optional model is FHS-3P) monitors the water flow state in the upstream pipe 101 in real time. When a water flow signal is detected, the controller automatically starts the servo motor 15 to drive the rotating gear rod 14 to work, thereby realizing intelligent linkage between drainage and impurity separation, avoiding idling loss, and realizing intelligent drainage management of "working with water and standing by without water".

[0047] In another embodiment of the present invention, the upstream pipe 101 and the downstream pipe 102 are both provided with a first supporting mechanism (such as Figure 8 、 Figure 9 As shown), they are respectively used to support the upstream pipe 101 and the downstream pipe 102, the first supporting mechanism includes a U-shaped frame 40 for supporting the upstream pipe 101 and / or the downstream pipe 102, and the two top ends of the U-shaped support frame 40 are fixedly installed with a first top plate 41 for being installed and connected to the tunnel top wall by bolts, and the top of the first top plate 41 is provided with a rubber pad with an arc-shaped top, and a first reinforcing rod 42 is fixedly connected between the inner walls on both sides of the U-shaped frame 40, and sliding holes are provided on both sides of the U-shaped frame 40, and the same pressing plate 43 is provided in the two sliding holes for pressing the upstream pipe 101 and / or the downstream pipe 102, and a second screw rod 44 is fixedly installed on the bottom inner wall of the two sliding holes, and the pressing plate 43 is slidably sleeved on the two second screw rods 44, and a nut is threadedly sleeved on the second screw rod 44 for pressing the pressing plate 43.

[0048] In this embodiment, the U-shaped frame 40 is tightly fitted to the tunnel top wall through the arc-shaped rubber pad of the first top plate 41, and the first reinforcing rod 42 arranged inside it improves the supporting strength; the pressure plate 43 slides up and down along the second screw rod 44 and is fastened with a nut to facilitate the assembly and disassembly of the support mechanism.

[0049] In another embodiment of the present invention, the water pipe 2 is equipped with two second supporting mechanisms (such as Figure 11 As shown), used to support the water pipe 2, the second supporting mechanism includes a supporting seat for supporting the water pipe 2 (as shown Figure 11 and Figure 12 As shown) 50 and a pressure seat 51 connected to the support seat 50 by bolts and used to compress the water pipe 2, two vertical rods 52 are symmetrically fixed on the pressure seat 51, and the tops of the two vertical rods 52 are fixedly connected with a second top plate 53 for installation and connection with the tunnel top wall by bolts, and the top of the second top plate 53 is also provided with a rubber pad with an arc top to adapt to the tunnel top wall, and a second reinforcing rod 54 is also fixedly installed between the two vertical rods 52.

At the same time, the arc-shaped rubber pad of the second top plate 53 effectively fits the top of the tunnel, improving adaptability and installation stability; various parts of the sponge tube 20 take turns to assume the main water absorption function, greatly reducing the replacement cycle, and the special rubber material of the ball 55 ensures smooth rotation without accidental displacement.

[0051] In another embodiment of the present invention, the two second reinforcing rods 54 are fixedly mounted with a same mounting plate 60, and the mounting plate 60 is mounted with a release mechanism (such as Figure 14As shown), it is used to support the water pipe 2 and release the water pipe 2 to make it descend after the support seat 50 is removed. The releasing mechanism includes: two drums 61 arranged above the mounting plate 60, and both ends of the two drums 61 are fixedly installed with a central shaft 62, and the rotating shaft 62 is rotatably mounted on the support seat 63 fixed on the mounting plate 60; a dual-axis motor 64 fixedly mounted on the top of the mounting plate 60, and the two output shafts of the dual-axis motor 64 are respectively fixedly connected to the corresponding two central shafts 62 through a coupling; wherein, a pull rope 65 is wound around the two drums 61, and the free end of the pull rope 65 is fixedly connected to a hook 67, and two support ropes 66 are wrapped around the water pipe 2, and both ends of the support rope 66 are fixedly connected to a hanging ring 68, and the two hanging rings 68 are hung on the hook 67.

[0052] In this embodiment, the release mechanism drives the two drums 61 to retract and release the pull rope 65 synchronously through the dual-axis motor 64, and cooperates with the support rope 66 and the hook 67 to form a stable pipeline lifting system. When maintenance is required, starting the dual-axis motor 64 can slowly lower the water pipe 2, preventing the water pipe 2 from falling directly after the connection with the telescopic tube 30 is released, thereby improving safety.

[0053] It is worth noting that the circuits, electronic components, and modules involved in the present invention are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods. In summary, compared with the related art, the setting of the hydrophilic polyurethane sponge tube 20 in this solution uses micropores to bind water, reduce the evaporation area, and inhibit the crystallization of calcium carbonate; By setting a separation mechanism and cooperating with the debris removal box 1, floating garbage and deposited impurities can be cleaned, and the reversible feature of the debris removal box 1 is utilized to improve the convenience of cleaning garbage and impurities; By providing the water pipe 2 and the sponge tube 20 with a rotatable function, the sponge tube can be fully utilized, reducing the replacement frequency and cost. In addition, the water pipe 2 can be easily removed by providing the telescopic tube 30, avoiding the telescopic tube 30 clamping the water pipe 2 and making it inconvenient to remove the water pipe 2. The setting of the release mechanism allows the water pipe 2 to be slowly lowered, reducing the risk of high-altitude disassembly and assembly.

[0054] It should be noted that the support mechanism in this solution can be installed on the top of the tunnel, or the rubber pads can be removed and the top plates (first top plate and second top plates) can be installed facing downward on the ground, which can also support the upstream pipe 101, the downstream pipe 102 and the water pipe 2.
