Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline technology, specifically an anti-clogging PVC drainage pipe for buildings. Background Technology
[0002] PVC drainage pipes are a type of building drainage pipe made primarily of sanitary-grade polyvinyl chloride resin, with the addition of stabilizers, lubricants, and other additives, through extrusion or injection molding. Due to their advantages such as corrosion resistance, smooth inner wall, low fluid resistance, low price, and convenient installation, they are widely used in building drainage, municipal engineering, and industrial wastewater transportation. Under normal operating conditions, their lifespan can reach over 50 years, making them an important replacement for traditional cast iron pipes. However, many existing PVC drainage pipe installations, especially in terms of anti-clogging and long-term maintenance, still have significant technical shortcomings, affecting the stability and efficiency of the drainage system.
[0003] Many existing PVC drainage pipes lack built-in, active anti-deposition designs, relying primarily on the natural flushing force of water flow for drainage. When wastewater contains fine particles, fibers, or grease, these substances easily deposit and solidify on the pipe walls, forming sediment. Over time, this sediment reduces the effective flow area of the pipe, increases flow resistance, and ultimately leads to blockage. Traditional solutions often rely on targeted tapping or high-pressure water jet flushing, but these methods have limited effectiveness, are not long-lasting, and require manual intervention, making preventative maintenance difficult. Especially in drainage environments with high particulate loads or uneven flow velocities, the risk of blockage increases significantly, impacting system reliability.
[0004] While some existing drain pipes have simple filters at the inlet, these devices are often bolted or embedded, making disassembly and cleaning extremely cumbersome. When the filter becomes covered with large debris, it must be removed manually with tools after the system is stopped, a time-consuming and labor-intensive process. More seriously, if cleaning is not timely, the filter itself may become a new blockage point, further hindering water flow. This reactive maintenance model increases long-term operating costs. Utility Model Content
[0005] The purpose of this utility model is to provide a clogging-resistant PVC drainage pipe for buildings, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A clog-resistant PVC drainage pipe for buildings, comprising a pipe, an anti-clogging mechanism, and a filtration mechanism; The anti-accumulation mechanism is set on the outer surface of the pipe. The anti-accumulation mechanism includes a sliding component, a driving component, and a striking component. The sliding component is set on the outer surface of the pipe, and the driving component and the striking component are both set on the sliding component. The filtration mechanism is located inside the pipe and includes a blocking component and a connecting component, both of which are located inside the pipe.
[0007] As a further embodiment of this utility model: the sliding assembly includes two guide rails, two slide blocks and a wheel ring. Each guide rail is fixedly installed on the outer surface of the pipe, the two slide blocks are slidably connected to the outer surfaces of the two guide rails respectively, and the wheel ring is fixedly installed on the outer wall of the two slide blocks.
[0008] As a further embodiment of this utility model: the drive assembly includes two mounting plates, a drive wheel, and a single-axis motor. Each mounting plate is fixedly mounted on the outer wall of the wheel ring. The drive wheel is rotatably connected between the two mounting plates. The single-axis motor is fixedly mounted on the outer wall of one of the mounting plates. The output end of the single-axis motor is fixedly connected to the side end of the drive wheel.
[0009] As a further embodiment of this utility model: the striking assembly includes a mounting base, a dual-axis motor, two rotating discs, two soft ropes, and two hollow balls. The mounting base is fixedly mounted on the outer wall of the wheel ring, the dual-axis motor is fixedly mounted on the bottom of the mounting base, the two rotating discs are respectively fixedly mounted on the two output shafts of the dual-axis motor, the two soft ropes are respectively fixedly mounted on the outer surface of the two rotating discs, and the two hollow balls are respectively fixedly mounted on the side ends of the two soft ropes.
[0010] As a further embodiment of this utility model: the blocking component includes a connecting groove, a mounting frame and a filter screen. The connecting groove is opened on the outer surface of the pipe, the mounting frame is slidably connected to the inside of the connecting groove, and the filter screen is fixedly installed inside the mounting frame.
[0011] As a further embodiment of this utility model: the connecting component includes two sliding grooves and two sliding rails. Each sliding groove is opened inside the connecting groove, and each sliding rail is fixedly installed on the outer wall of the mounting frame. The two sliding rails are slidably connected to the interior of the two sliding grooves respectively.
[0012] As a further embodiment of this invention: both hollow spheres are made of rubber material, and a handle is provided on the top of the mounting frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This device's anti-accumulation mechanism, through the synergistic design of its unique sliding, driving, and striking components, constructs an automatic cleaning system that can move along the outer wall of the pipe, effectively solving the problem of particulate matter deposition on the pipe wall. Its core lies in the single-axis motor in the driving component, which drives the active wheel to rotate, relying on friction to drive the driven wheel on the wheel ring, enabling the entire mechanism to move along the guide rail along the entire length of the pipe's outer wall. Simultaneously, the dual-axis motor in the striking component drives a rotating disc, which, through a soft rope, pulls a hollow rubber ball to continuously and uniformly strike the pipe wall at a high frequency. This "movement + full-area striking" mode generates vibration waves that are transmitted into the pipe, effectively disrupting the deposition process of fine particles in the sewage and preventing them from accumulating and solidifying on the inner wall. This significantly reduces the risk of blockage caused by the reduction in the internal flow area of the pipe due to long-term use. Compared to traditional solutions that can only strike at fixed points or rely entirely on water flow, this dynamic anti-accumulation method has a wider range of action and a more thorough anti-clogging effect, making it particularly suitable for drainage environments prone to sedimentation.
[0014] 2. The filtration mechanism of this device features a highly efficient and easy-to-maintain pretreatment unit at the inlet. Its core component is a barrier assembly, which slides directly into the connecting groove at the pipe inlet via a mounting frame with a filter screen. This design effectively intercepts large solid impurities in wastewater, preventing them from entering deep into the pipe and causing serious blockages. The sliding rails and grooves in the connecting assembly ensure stable positioning of the mounting frame within the connecting groove, resisting the impact of water flow and preventing shaking or abnormal noise during operation. More importantly, its modular quick-release design allows for easy removal of the filter screen: when cleaning is needed, operators can simply pull the entire mounting frame directly out of the connecting groove using the handle on top for quick cleaning or replacement, and then easily reinsert it. This design greatly simplifies daily maintenance, avoiding the inconvenience of cleaning traditional fixed filter screens, effectively ensuring the durability of the filtration effect, and significantly reducing the difficulty and time cost of long-term maintenance.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0023] The present invention provides the following preferred embodiments: Example 1, as Figures 1-6 As shown, an anti-clogging PVC drainage pipe for buildings includes a pipe 1, and also includes an anti-clogging mechanism and a filtering mechanism; The anti-accumulation mechanism is set on the outer surface of the pipe 1. The anti-accumulation mechanism includes a sliding component, a driving component, and a striking component. The sliding component is set on the outer surface of the pipe 1, and the driving component and the striking component are both set on the sliding component. The filter mechanism is located inside the pipe 1. The filter mechanism includes a blocking component and a connecting component, both of which are located inside the pipe 1.
[0024] like Figures 1-2 As shown, the sliding assembly includes two guide rails 2, two slide blocks 3, and a wheel ring 4. Each guide rail 2 is fixedly installed on the outer surface of the pipe 1. The two slide blocks 3 are slidably connected to the outer surfaces of the two guide rails 2 respectively. The wheel ring 4 is fixedly installed on the outer wall of the two slide blocks 3. The wheel ring 4 consists of an annular bracket and three driven wheels. The three driven wheels are all in contact with the outer surface of the pipe 1. The wheel ring 4 is slidably connected to the outer surface of the pipe 1 through the cooperation of the guide rails 2 and the slide blocks 3. When the drive assembly is started, the wheel ring 4 can drive the striking assembly to move on the outer surface of the pipe 1.
[0025] like Figures 2-4 As shown, the drive assembly includes two mounting plates 5, a drive wheel 6, and a single-axis motor 7. Each mounting plate 5 is fixedly mounted on the outer wall of the wheel ring 4. The drive wheel 6 is rotatably connected between the two mounting plates 5. The single-axis motor 7 is fixedly mounted on the outer wall of one of the mounting plates 5. The output end of the single-axis motor 7 is fixedly connected to the side end of the drive wheel 6. The drive wheel 6 is in contact with one of the driven wheels on the wheel ring 4. The single-axis motor 7 is started by an external controller. When the single-axis motor 7 runs, it drives the drive wheel 6 to rotate. When the drive wheel 6 rotates, it drives the driven wheel to rotate through friction, thereby causing the wheel ring 4 to move the striking assembly.
[0026] like Figures 2-5 As shown, the striking assembly includes a mounting base 8, a dual-axis motor 9, two rotating discs 10, two flexible ropes 11, and two hollow balls 12. The mounting base 8 is fixedly installed on the outer wall of the wheel ring 4. The dual-axis motor 9 is fixedly installed at the bottom of the mounting base 8. The two rotating discs 10 are respectively fixedly installed on the two output shafts of the dual-axis motor 9. The two flexible ropes 11 are respectively fixedly installed on the outer surface of the two rotating discs 10. The two hollow balls 12 are respectively fixedly installed on the side ends of the two flexible ropes 11. The dual-axis motor 9 is started by the outer wall controller. When the dual-axis motor 9 runs, it drives the rotating discs 10 on both sides to rotate. When the rotating discs 10 rotate, they drive the flexible ropes 11 to rotate. During the rotation of the flexible ropes 11, they drive the hollow balls 12 to continuously strike the outer wall of the pipe 1. The pipe 1 is a PVC drainage pipe with a relatively thick wall, which can prevent fine dust that escapes from the filter mechanism from accumulating on the inner wall of the pipe 1 and forming a blockage. With the movement of the sliding assembly, the pipe 1 can be struck throughout to prevent deposition.
[0027] like Figures 1-6 As shown, the blocking assembly includes a connecting groove 13, a mounting frame 14, and a filter screen 15. The connecting groove 13 is formed on the outer surface of the pipe 1, the mounting frame 14 is slidably connected to the inside of the connecting groove 13, and the filter screen 15 is fixedly installed inside the mounting frame 14. The filter screen 15 is located at the water inlet of the pipe 1, thereby blocking large pieces of dirt and preventing serious blockage inside the pipe 1. Since the mounting frame 14 and the connecting groove 13 are slidably connected, the filter screen 15 can be cleaned by pulling out the mounting frame 14 after long-term use.
[0028] like Figures 1-6 As shown, the connecting assembly includes two slide grooves 16 and two slide rails 17. Each slide groove 16 is formed inside the connecting groove 13, and each slide rail 17 is fixedly installed on the outer wall of the mounting frame 14. The two slide rails 17 are slidably connected to the interior of the two slide grooves 16 respectively. The presence of the slide rails 17 and slide grooves 16 makes the sliding connection of the mounting frame 14 inside the connecting groove 13 more stable, avoiding the shaking of the mounting frame 14 due to the impact of water flow.
[0029] like Figures 3-6 As shown, both hollow spheres 12 are made of rubber. The top of the mounting frame 14 is equipped with a handle. The hollow rubber material can provide sufficient impact force without damaging the pipe 1. The handle makes it easy for workers to lift the mounting frame 14.
[0030] The specific working process of this utility model is as follows: First, the blocking component of the filtration mechanism begins to operate. The filter screen 15, installed at the inlet of pipe 1, performs preliminary filtration of the water flowing through pipe 1, intercepting large pieces of dirt and preventing them from entering the depths of pipe 1 and causing serious blockage. The filter screen 15 is installed in the connecting groove 13 via the mounting frame 14 and is kept stable by the sliding engagement of the sliding rail 17 and the sliding groove 16 of the connecting component. When cleaning or replacement is required, it can be pulled out entirely via the handle on the top of the mounting frame 14. At the same time, the anti-accumulation mechanism is activated to prevent the deposition of fine particles: the single-axis motor 7 of the drive component is activated by the external controller, driving the drive wheel 6 to rotate. The friction drives the driven wheel on the wheel ring 4, causing the entire wheel ring 4 and its striking component to move slowly along the guide rail 2 on the outer surface of pipe 1. Then, the dual-axis motor 9 of the striking component is activated, driving the two rotating disks 10 to rotate, causing the rubber hollow balls 12 at the ends of the soft ropes 11 attached to the disks to continuously and cyclically strike the outer wall of pipe 1. The resulting vibration is transmitted to the inside of pipe 1, causing any fine particles that may have deposited to detach from the pipe wall and be washed away by the water flow. By moving the sliding component at a constant speed, dynamic anti-deposition treatment can be achieved throughout the entire length of the pipeline, effectively solving the blockage problem caused by particle deposition.
[0031] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
