Description

Technical Field

[0001] This application relates to the field of anti-seepage devices, and in particular to an anti-seepage mechanism for water supply and drainage pipes. Background Technology

[0002] In municipal construction and environmental management projects, water supply and drainage systems account for a significant portion of the investment. With the continuous development of urban construction, municipal pipeline types have diversified, and water supply and drainage pipes play a crucial role in urban water supply and drainage systems. They are widely used in various settings, including residential, commercial, industrial, and municipal sectors, primarily for water supply, drainage, and hot and cold water transmission, thereby maintaining urban environmental sanitation and the quality of life for residents. However, existing drainage pipes are typically installed with the interior completely sealed. As liquid is discharged, the pressure inside the pipe exceeds that outside, causing the liquid to gradually seep out and damage the drainage pipe. Utility Model Content

[0003] To address the problem that conventional drainage pipe sealing installations result in inconsistent air pressure inside and outside the pipe, accelerating liquid seepage and easily causing damage to the drainage pipe, this application provides a seepage prevention mechanism for water supply and drainage pipes.

[0004] The water supply and drainage pipe seepage prevention mechanism provided in this application adopts the following technical solution:

[0005] A seepage prevention mechanism for water supply and drainage pipes includes an outer pipe body, a connecting layer provided on the inner wall of the outer pipe body, a squeezing cavity for squeezing movement provided between the connecting layer and the outer pipe body, a support ring provided in the squeezing cavity, the outer surface of the support ring being fixedly connected to the inner wall of the outer pipe body, and an inner pipe body for discharging water provided on the inner wall of the connecting layer.

[0006] Multiple extrusion rods are provided on one side of the support ring in the extrusion chamber. The multiple extrusion rods are rotatably connected to the support ring. One end of each of the multiple extrusion rods passes through the connecting layer and the inner tube in sequence, and the passing end is located inside the inner tube. An extrusion plate is fixed on the side of the multiple extrusion rods away from the passing end. The multiple extrusion plates are fixed to the outer surface of the connecting layer.

[0007] By adopting the above technical solution, the liquid flows into the inner pipe body and impacts the squeezing rod. The squeezing rod is centered on the support ring, and the support ring connects the outer pipe body and the connecting layer to form an integral fixation, which improves the stability of the pipeline. This causes the squeezing rod to squeeze the connecting layer, allowing the liquid and gas that have seeped into the inner pipe body to be discharged to the outside. This avoids liquid seepage caused by the pressure difference between the inside and outside of the pipeline, thus making it less likely to damage the drain pipe.

[0008] Preferably, a rotating locking block is fixedly arranged around the inner surface of the support ring, and a locking groove is opened on the side of the plurality of pressing rods near the rotating locking block, and the plurality of locking grooves are rotatably engaged with the rotating locking block.

[0009] By adopting the above technical solution, the rotating block and the slot are rotated and engaged, so that when the extrusion rod is subjected to pressure, it rotates around the engagement point of the rotating block, thereby applying pressure to the connecting layer.

[0010] Preferably, the inner tube surface is provided with mounting grooves at the positions of multiple extrusion plates, and each of the multiple mounting grooves is sealed with a permeation inner plate for liquid permeation.

[0011] By adopting the above technical solution, the opening of the installation groove provides a fixed space for the installation of the permeable inner plate, while the permeable inner plate is in contact with the liquid, thereby receiving the internal air pressure and part of the liquid.

[0012] Preferably, the connecting layer has permeation chambers at the positions of multiple extrusion plates, the bottom of each permeation chamber penetrates the inner surface of the connecting layer, and a permeation outer plate is sealed at the penetration opening.

[0013] By adopting the above technical solution, the outer permeation plate is aligned with the inner permeation plate to receive the moisture and gas pressure discharged from the inner permeation plate and transport them to the permeation chamber for temporary storage, thereby reducing the gas pressure inside the inner tube.

[0014] Preferably, each of the multiple permeation chambers has a discharge port extending through the outer surface of the connecting layer on one side of its top.

[0015] By adopting the above technical solution, the discharge port is connected to the outside through the connecting layer, which facilitates the discharge of gas and liquid in the permeation cavity, thereby reducing the gas pressure inside the inner tube.

[0016] Preferably, the outer surface of the outer tube has slots at the locations of multiple discharge ports, the multiple slots are connected to the discharge ports, and filter cotton is fixed in each of the multiple slots.

[0017] By adopting the above technical solution, the slot is connected to the discharge port, thereby receiving the gas pressure and liquid discharged from the permeation chamber. At the same time, the liquid is filtered by the filter cotton, thereby reducing the discharge speed.

[0018] Preferably, the surface of the connecting layer has movable outer openings at the through ends of the multiple extrusion rods, and the surface of the inner tube has movable inner openings at the through ends of the multiple extrusion rods, with the movable inner openings aligned and connected to the movable outer openings.

[0019] By adopting the above technical solution, the movable outer port penetrates the connecting layer, the movable inner port penetrates the inner tube body, and the movable inner port is connected to the movable outer port, thereby providing a space for the pressing and pressing out of the extrusion rod to form an extrusion action.

[0020] Preferably, multiple sealing covers are fixedly provided on the inner surface of the inner tube at the positions where multiple extrusion rods pass through, and each of the multiple sealing covers has a force-bearing arc surface recessed on the side facing the water discharge.

[0021] By adopting the above technical solution, the sealing cover seals and covers the through ends of multiple extrusion rods, thereby preventing liquid from flowing out through the through gaps of the extrusion rods. At the same time, the force-bearing arc surface increases the contact area with the liquid, thereby increasing the pressure applied to the through ends.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When liquid passes through the inner tube, it enters the permeation chamber through the inner and outer permeation plates, which in turn drives the internal gas to enter simultaneously. At the same time, the liquid comes into contact with the sealing cover and generates an impact, causing the squeezing rod to rotate around the rotating block. This causes the squeezing plate to squeeze the connecting layer located in the permeation chamber, expelling the liquid and gas in the permeation chamber to the outside. This avoids the problem of inconsistent air pressure inside and outside the pipe, which can easily lead to damage to the drain pipe due to liquid seepage. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses a seepage prevention mechanism for water supply and drainage pipes.

[0033] Reference Figure 1 , Figure 2 , Figure 4 A seepage prevention mechanism for water supply and drainage pipes includes an outer pipe body 1. A support ring 5 is fixed inside the pipe of the outer pipe body 1. The support ring 5 is made of polytetrafluoroethylene (PTFE) to provide sufficient support. A rotating block 8 is protruding from the inner ring of the support ring 5. The surface of the rotating block 8 is round and smooth. A connecting layer 2 is fixed inside the annular inner ring of the rotating block 8. An inner pipe body 3 is fixedly attached to the inner surface of the connecting layer 2. The inner pipe body 3 is made of stainless steel to ensure good hygiene when in direct contact with liquid. A squeezing chamber 4 is set between the connecting layer 2 and the outer pipe body 1. The support ring 5 is located in the squeezing chamber 4 and fixedly connected to the outer pipe body 1. At the same time, multiple slots 12 (at least six slots 12) are opened around the outer surface of the outer pipe body 1. Each slot 12 is filled with filter cotton 20. Collection or discharge structures are set at the positions of the multiple slots 12 on the outside.

[0034] It should be noted that the connecting layer 2 has permeation chambers 14 at the positions of multiple slots 12. The top of the permeation chamber 14 has a discharge port 15 that penetrates the outer surface of the connecting layer 2. The multiple discharge ports 15 are connected to the multiple slots 12 one by one, and the connection points are filled with sealant. At the same time, the other side of the permeation chamber 14, relative to the discharge port 15, penetrates the inner surface of the connecting layer 2 and contacts the inner tube 3. A permeation outer plate 16 is sealed and fixed at the penetration point. The permeation outer plate 16 is made of polyethylene terephthalate and has a certain degree of permeability. The inner tube 3 has mounting grooves 18 at the positions of multiple permeation outer plates 16. A permeation inner plate 19 is sealed and fixed in each of the multiple mounting grooves 18. The permeability of the permeation inner plate 19 is lower than that of the permeation outer plate 16.

[0035] The inner wall of the inner tube 3 is in direct contact with the liquid, and the transmitted vibration is received by the connecting layer 2. At the same time, the connecting layer 2 is fixed to the outer tube 1 through the support ring 5, thus forming an integral fixation. The extrusion chamber 4 is located between the connecting layer 2 and the outer tube 1 to relieve the transmitted vibration and ensure the stability of the pipeline when discharging liquid. Then, the permeable outer plate 16 and permeable inner plate 19 installed on the surface of the connecting layer 2 and the inner tube 3 provide discharge space for the permeation of liquid and air, thereby preventing the pipeline from being completely permeated due to the difference in air pressure between the inner tube 3 and the outside. This allows the liquid to permeate regularly into the area where the permeable inner plate 19 is located and be introduced into the external storage structure.

[0036] Reference Figure 3 , Figure 4 , Figure 5Multiple extrusion rods 6 are connected around the circular surface of the rotating block 8. The multiple extrusion rods 6 are arranged around the connecting layer 2. Each of the multiple extrusion rods 6 has a fitting groove 9 at the connection point of the rotating block 8. The groove 9 is movably engaged with the surface of the rotating block 8, thus forming a rotatable but immovable state. One end of each of the multiple extrusion rods 6 passes through the connecting layer 2 and the inner tube 3 in sequence and is located on the inner surface of the inner tube 3. The end of the multiple extrusion rods 6 is triangular in shape, and the inclined surface of the triangle is facing the liquid inflow end. The other end of the multiple extrusion rods 6 extends from the extrusion chamber 4 to the permeation chamber 14. An extrusion plate 7 is fixed at the extended end. The surface of the extrusion plate 7 is fixed to the outer surface of the connecting layer 2.

[0037] It should be noted that the inner tube 3 is covered with a sealing cover 10 at the penetration points of the multiple extrusion rods 6. The sealing cover 10 is sealed to the inner wall of the inner tube 3, and the side of the sealing cover 10 facing the liquid inflow is recessed inward to form a force-bearing arc surface 11 to increase the force-bearing area. The part of the connecting layer 2 that is fixed to the extrusion plate 7 is made of rubber and can be deformed by the extrusion from the extrusion plate 7. At the same time, the connecting layer 2 has multiple movable external openings 13 at the penetration points of the multiple extrusion rods 6, and the inner tube 3 has multiple movable internal openings 17 at the penetration points of the multiple extrusion rods 6, thereby providing space for the rotation of the extrusion rods 6.

[0038] Liquid flows into the inner tube 3 and contacts the force-bearing arc surface 11, thereby applying a thrust to the through end of the extrusion rod 6. At the same time, the extrusion rod 6 rotates around the locking point of the rotating block 8, causing the other end of the extrusion rod 6 to press downward, which in turn drives the extrusion plate 7 to apply downward pressure to the surface of the connecting layer 2. The permeation chamber 14 is subjected to pressure, which compresses the internal air and liquid, forcing the air and liquid to be squeezed into the slot 12 from the discharge port 15. The air and liquid are intercepted by the filter cotton 20, which slows down the discharge speed and reduces the pressure difference between the inside and outside of the inner tube 3. At the same time, some liquid enters the permeation chamber 14 from the permeation inner plate 19 and the permeation outer plate 16, providing auxiliary outlet for liquid permeation and effectively preventing damage to the pipeline caused by permeation.

[0039] The implementation principle of the anti-seepage mechanism for water supply and drainage pipes in this application embodiment is as follows: When using this device, liquid flows in from one side of the inner pipe body 3. As the inner pipe body 3 continues to discharge liquid, the liquid comes into contact with the inner permeation plate 19, thereby permeating inward with liquid and air. Then, the inner permeation plate 19 enters the outer permeation plate 16 and is finally temporarily stored in the permeation chamber 14. At the same time, due to the double-layer isolation between the inner permeation plate 19 and the outer permeation plate 16, the permeation speed is slow, thereby avoiding affecting the overall liquid discharge of the pipeline.

[0040] Then, it comes into contact with the sealing cover 10 to form a thrust. At the same time, when the liquid impacts the force-bearing arc surface 11, it causes a brief pause, which increases the thrust on the sealing cover 10. The sealing cover 10 applies a squeezing force to the through end of the squeezing rod 6. The squeezing rod 6 is squeezed and rotates around the rotating block 8, thereby converting the squeezing force into downward pressure applied to the surface of the squeezing plate 7. The surface of the squeezing plate 7 is subjected to pressure and simultaneously applies pressure to the connecting layer 2. The connection part between the connecting layer 2 and the squeezing plate 7 is made of rubber and can be deformed, thereby squeezing out the liquid and gas temporarily stored in the permeation chamber 14 from the discharge port 15.

[0041] The discharge port 15 is aligned with the slot 12, allowing the liquid and gas to undergo secondary filtration with the filter cotton 20 before being discharged into the external storage structure. During the discharge process, the discharge speed is reduced to maintain normal discharge of the inner tube 3, thereby ensuring that the air pressure inside and outside the pipeline is consistent, effectively reducing liquid permeation. At the same time, the permeated liquid is regularly discharged to the outside through the designated permeation chamber 14, extending the service life of the pipeline.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
