Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically to a self-cleaning water supply pipeline. Background Technology

[0002] Water supply pipelines are pipeline systems used to transport various types of water for domestic, industrial, and fire-fighting purposes. They are core infrastructure ensuring urban water supply, building water supply, and industrial water use. Their core function is to safely and stably deliver water that meets water quality standards from water sources (such as reservoirs and water plants) or water storage facilities (such as water towers and water tanks) to end users (such as household faucets, industrial equipment, and fire hydrants). During long-term use, external impurities enter the pipelines with the water flow, accumulating and forming blockages. What may seem like a minor problem of "reduced water flow" can actually trigger a chain reaction from water use failure to safety accidents, causing multi-dimensional harm to daily life, production, and even building safety.

[0003] Conventional water supply pipes lack self-cleaning capabilities and can only rely on water flow to carry some impurities out of the pipes. As usage time increases, impurities or foreign objects accumulate inside the pipes, causing blockages. Cleaning blockages using high-pressure water jets, chemical cleaners, or mechanical scrapers is time-consuming, labor-intensive, and costly. Summary of the Invention

[0004] This invention provides a self-cleaning water supply pipe, which aims to achieve a certain degree of self-cleaning without consuming additional energy, thereby preventing pipe blockage.

[0005] This invention is achieved through the following technical solution: a self-cleaning water supply pipe, comprising: The main shaft is fixed inside the pipe along the pipe axis; A rotating assembly is rotatably mounted on the main shaft. The rotating assembly includes a blade, an annular connector, and at least one protrusion. One end of the blade is rotatably connected to the main shaft, and the other end of the blade is fixed to the annular connector. The protrusion is connected to the outer circumferential surface of the annular connector. The pipe body includes a rigid pipe and an elastic wall. The elastic wall is coaxially disposed inside the rigid pipe. An elastic support is connected between the rigid pipe and the elastic wall. A gap that can accommodate fluid is formed between the elastic wall and the rigid pipe. The elastic wall is serrated. The blade can drive the annular connector and the protrusion to rotate around the main axis under the drive of the fluid in the pipe, so that the protrusion impacts the serrated surface of the elastic wall.

[0006] Compared with existing technologies, this solution has the following advantages and beneficial effects: During use, the water flow inside the pipe is fast. The blades in the rotating component rotate around the main shaft under the action of the water flow, which drives the annular connector and the protrusion to rotate together. This causes the protrusion to continuously impact the elastic wall, creating vibration. This bounces up any impurities or foreign objects that may be attached to or deposited on the elastic wall, and carries them out of the pipe with the water flow, preventing them from clogging the pipe.

[0007] This solution minimizes the likelihood of impurities and foreign objects adhering to the inner wall of the pipe (i.e., the elastic wall in this solution) without consuming additional energy, thereby reducing the risk of pipe blockage and consequently reducing maintenance costs.

[0008] In this design, the protrusions periodically impact the serrated surface of the elastic wall as the rotating component rotates, generating high-frequency vibrations. These vibrations directly act on impurities such as scale, silt, and microbial films adhering to the inner side of the elastic wall, breaking the adhesion between the impurities and the wall surface, causing them to peel off and bounce off the elastic wall surface.

[0009] The impurities that are vibrated and bounced up are directly carried away by the continuously flowing water in the pipe, without the need for additional disassembly and cleaning or the use of chemical descaling agents. This achieves a closed-loop self-cleaning process of water flow driving rotation - rotation generating vibration - vibration stripping impurities - water flow discharging impurities, thus preventing pipe blockage caused by impurity accumulation from the root.

[0010] In this solution, the elastic support is used to fix the elastic wall, ensure the basic shape of the elastic wall, and can reset after the protrusion hits the elastic wall. This cycle of impact deformation-reset rebound allows the elastic wall to generate additional small vibrations after a single impact, prolonging the vibration duration and more fully peeling off the attached stubborn impurities (such as scale).

[0011] The serrated surface of the elastic wall can change the impact contact mode of the protrusion. Compared with the planar structure, the teeth of the serration can form point / line contact with the protrusion, concentrate the impact stress, and improve the local vibration intensity. At the same time, the groove can accommodate some flowing water to help flush away the small impurities that have been peeled off, further improving the cleaning efficiency.

[0012] The gap between the rigid pipe and the elastic wall can accommodate fluid (such as water at the same pressure as the supply water), which can balance the pressure on both sides of the elastic wall. This prevents excessive deformation of the elastic wall due to excessive supply water pressure in the pipe, and also prevents the elastic wall from sticking to the rigid pipe due to vibration due to insufficient pressure. This ensures that the elastic wall is not easily damaged during long-term impact and extends its service life.

[0013] The entire self-cleaning process relies on mechanical vibration and water flow, requiring no addition of descaling agents, disinfectants, or other chemicals, and does not alter the composition of the water supply. Furthermore, compared to traditional water supply pipes that require regular disassembly and cleaning, the pipe structure in this solution allows for cleaning as needed, reducing the frequency and cost of manual maintenance.

[0014] Furthermore, the rotating assembly also includes a bearing, the inner ring of which is coaxially fixed to the main shaft, and the outer ring of which is fixedly connected to one end of the blade.

[0015] Beneficial effects: In this design, the blades are rotatably connected to the main shaft via bearings. The bearings reduce the friction between the blades and the main shaft, making it easier for the blades to rotate smoothly under the action of water flow.

[0016] Furthermore, the elastic wall is a thin film structure, and the material of the elastic wall is any one of fluoropolymer, engineering plastic, elastomer or metal sheet.

[0017] Beneficial effects: The elastic wall in this solution has a thin film structure. When the protrusion is impacted, it can generate rapid and small elastic deformation. During the deformation process, high-frequency micro-vibration of impact-rebound will be generated. This vibration can be directly transmitted to the inner side of the elastic wall, which can more efficiently remove attached scale, mud and other impurities. Compared with thick-walled structures (such as rigid plates), the vibration transmission loss is smaller and the cleaning efficiency can be improved.

[0018] The thin-film structure is lightweight and only requires a small impact force from the protrusions of the rotating component to make it vibrate. No additional water flow thrust or power is needed. It is perfectly suited to the low-energy design of water flow driven rotating components, avoiding the difficulty of starting the rotating component due to excessive weight of the elastic wall, and ensuring that the self-cleaning function can still be effective under low water flow conditions.

[0019] Furthermore, multiple elastic support members are provided, and each elastic support member is a spring, with the multiple springs evenly distributed along the circumference of the rigid tube.

[0020] Beneficial effects: Multiple springs are evenly distributed along the circumference of the rigid tube, distributing the supporting force of the elastic wall to multiple points on the circular trajectory. This ensures balanced force across all areas of the elastic wall, preventing deformation due to uneven local stress and ensuring long-term stability of the overall shape. The impact position and force remain consistent throughout. It also prevents localized sagging or concavity of the elastic wall caused by concentrated support points, maintaining the preset contour opposite to the protrusions and fundamentally avoiding impact misalignment and cleaning failure.

[0021] Furthermore, the inner surface of the elastic wall is a smooth surface.

[0022] Beneficial effects: This design reduces the likelihood of impurities and foreign objects adhering to the surface of the elastic wall, and makes it easier for impurities and foreign objects to detach from the elastic wall during the vibration process caused by the protrusion hitting the elastic wall.

[0023] Furthermore, the protrusions are provided in multiple ways, and the multiple protrusions are evenly distributed along the circumference of the annular connector. The serrated surface of the elastic wall includes multiple spaced teeth and grooves. During rotation, the protrusions alternately pass through the grooves and impact the teeth.

[0024] Beneficial effects: When multiple evenly distributed protrusions rotate with the annular connector, they create continuous impacts. Compared to a single protrusion requiring a full rotation cycle after each impact, multiple protrusions can initiate multiple impacts on the serrated surface of the elastic wall within the same rotation cycle, increasing the impact frequency several times. This high-frequency vibration can more quickly break the adhesion between impurities and the elastic wall, significantly improving cleaning efficiency.

[0025] The protrusions are evenly distributed circumferentially, and together with the uniform teeth on the serrated surface of the elastic wall, the impact point can be ensured to cover the entire circumference of the elastic wall, avoiding cleaning dead corners caused by impacts concentrated in local areas, and achieving uniform cleaning of the entire inner side of the elastic wall, thereby improving the cleaning effect.

[0026] Furthermore, the cross-sections of both the teeth and the protrusions are triangular or trapezoidal, and the width of the groove is greater than the width of the protrusion.

[0027] Beneficial effects: In this design, the cross-sectional shape of the teeth and protrusions of the elastic wall is triangular or trapezoidal, which makes the root of the teeth and protrusions wider, thus enhancing the bending strength of the protrusions. Compared with rectangular protrusions with the same width at the end and the root, they are less prone to fracture due to stress concentration at the root under long-term high-frequency impact.

[0028] The trough is wider than the protrusion. The wider trough can accommodate small impurities that are dislodged by vibration, preventing impurities from getting stuck between the protrusion and the trough (causing rotational jamming). At the same time, the width of the trough can work with the water flow in the pipe to form a drainage channel, allowing the water flow to carry away impurities in the trough more smoothly, reducing the temporary accumulation of impurities in the trough and further reducing the risk of pipe blockage.

[0029] Furthermore, the portion of the protrusion that strikes the tooth has a rounded corner.

[0030] Beneficial effects: If the impact point is a sharp corner, the stress will concentrate at the tip of the corner, and long-term high-frequency impact can easily cause the tip of the protrusion to crack. At the same time, the sharp corner may also pierce / tear the teeth of the elastic wall. Rounded corners can disperse the concentrated stress into surface stress, which can significantly reduce the risk of the protrusion breaking and the teeth of the elastic wall tearing, thereby extending the service life of both.

[0031] Furthermore, the protrusion is hollow inside.

[0032] Beneficial effect: This design reduces the weight of the protrusion and decreases the rotational resistance of the entire rotating assembly.

[0033] Furthermore, the rotating assembly is provided in multiple parts, and the multiple rotating assemblies are distributed at intervals along the axial direction of the main shaft.

[0034] Beneficial effects: A single rotating component can only cover a local axial area of ​​its location, while multiple rotating components distributed axially at intervals can be segmented and spliced ​​to form a cleaning range covering the entire length of the pipe, thereby improving cleaning effectiveness and efficiency.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0038] As one embodiment of this application, such as Figures 1-3 As shown, this embodiment provides a self-cleaning water supply pipe, including: Main shaft 1 is fixed inside the pipe along the pipe axis. Specifically, brackets are welded and fixed at both ends of the pipe and on its inner side. Main shaft 1 is welded and fixed to the brackets, so that main shaft 1 is fixed in the center of the pipe. A rotating assembly is rotatably mounted on a main shaft 1. The rotating assembly includes blades 3, annular connectors 4, and at least one protrusion 5. One end of the blades 3 is rotatably connected to the main shaft 1, and the other end of the blades 3 is fixed to the annular connectors 4. The protrusion 5 is connected to the outer circumferential surface of the annular connectors 4. In this embodiment, the annular connectors 4 are circular rings. The rotating assembly also includes a bearing 2. The inner ring of the bearing 2 is coaxially fixed to the main shaft 1, and the outer ring of the bearing 2 is welded and fixed to one end of the blades 3. The blades 3 are rotatably connected to the main shaft 1 through the bearing 2. The rotating assembly has multiple blades 3, which are evenly distributed around the bearing 2. In this embodiment, the blades 3 are welded and fixed to the inner side of the annular connectors 4, while the protrusion 5 is welded and fixed to the outer side of the annular connectors 4. The pipe body includes a rigid pipe 7 and an elastic wall 6. The elastic wall 6 is coaxially disposed inside the rigid pipe 7. An elastic support is connected between the rigid pipe 7 and the elastic wall 6. In this embodiment, multiple elastic supports are provided, and the elastic supports are springs 9. Multiple springs 9 are evenly distributed along the circumference of the rigid pipe 7. The arrangement of springs 9 can provide support for the elastic wall 6 and ensure the basic shape of the elastic wall 6. In this embodiment, a ring for connecting springs 9 is integrally provided on the side of the rigid pipe 7 and the elastic wall 6 that are directly opposite each other. The two ends of springs 9 are hooked onto the rings of the rigid pipe 7 and the elastic wall 6, respectively. A gap is formed between the elastic wall 6 and the rigid pipe 7 to accommodate fluid. Liquid is filled into the gap between the elastic wall 6 and the rigid pipe 7. In this embodiment, the liquid is water 8. This ensures that the elastic wall 6 is subjected to balanced pressure from the water 8 on both sides during the process of water flowing through the pipe body, and can prevent the elastic wall 6 from undergoing large deformation under gravity. In this embodiment, the elastic wall 6 has a circular cross-section and is serrated. The serrations of the elastic wall 6 are opposite to the protrusions 5. Driven by the fluid in the pipe, the blade 3 can drive the annular connector 4 and the protrusions 5 to rotate around the main shaft 1, so that the protrusions 5 continuously impact the serrated surface of the elastic wall 6, thereby causing the elastic wall 6 to vibrate. This will cause any impurities or foreign objects that may be attached or deposited to be bounced up and carried out of the pipe with the water flow, thus preventing them from clogging the pipe.

[0039] The rigid pipe 7 in this embodiment can be made of metal or hard plastic. In this embodiment, the rigid pipe 7 is a metal pipe. The metal pipe can protect the overall structure and reduce the damage to the pipe caused by external forces.

[0040] In one embodiment, the elastic wall 6 is a thin film structure, and the material of the elastic wall 6 is any one of fluoropolymer, engineering plastic, elastomer, or metal sheet. The fluoropolymer is polytetrafluoroethylene or ethylene-tetrafluoroethylene copolymer, the engineering plastic is polypropylene or polycarbonate, the elastomer is ethylene propylene diene monomer (EPDM) rubber or silicone rubber, and the thickness of the metal sheet is 1-3 mm. In this embodiment, the elastic wall 6 is preferably made of fluoropolymer.

[0041] In one embodiment, the inner surface of the elastic wall 6 is a smooth surface, and the surface roughness Ra of the elastic wall 6 needs to be ensured to be ≤0.8μm during the processing to reduce the adhesion of impurities to the elastic wall 6. For example, a uniform smooth film layer can be formed on the inner wall of the elastic wall 6 by a brushing process.

[0042] In one embodiment, such as Figure 1 As shown, multiple protrusions 5 are provided, and the multiple protrusions 5 are evenly distributed along the circumference of the annular connector 4. The serrated surface of the elastic wall 6 includes multiple spaced teeth and grooves. During rotation, the protrusions 5 alternately pass through the grooves and impact the teeth, thereby causing the elastic wall 6 to vibrate continuously, which shakes off the impurities attached to the inner surface of the elastic wall 6. In this embodiment, the number of protrusions 5 is the same as the number of grooves in the elastic wall 6.

[0043] In one embodiment, such as Figure 1 As shown, the cross-sections of the teeth and the protrusions 5 are both triangular or trapezoidal. The root width of the teeth and the protrusions 5 is greater than the end width, and the width of the groove is greater than the width of the protrusions 5. In this embodiment, the cross-sections of the teeth of the elastic wall 6 and the protrusions 5 on the annular connector 4 are both trapezoidal.

[0044] In one embodiment, the part of the protrusion 5 that impacts the tooth is provided with rounded corners. Specifically, in this embodiment, both sides of the end of the trapezoidal columnar protrusion 5 (i.e., the end corners) are rounded. In this embodiment, the end corners of the teeth of the elastic wall 6 are also rounded, so that the end corners of the protrusion 5 and the teeth of the elastic wall 6 are smoothly transitioned, avoiding sharp collision contact between the two and causing damage to both, thereby extending the service life of both the elastic wall 6 and the protrusion 5.

[0045] In one embodiment, the protrusion 5 is hollow inside. Specifically, the protrusion 5 is a hollow stainless steel structure, which can reduce the weight of the protrusion 5, making the entire rotating assembly lighter and reducing the rotational resistance of the blade 3.

[0046] In one embodiment, multiple rotating components are provided, and the multiple rotating components are distributed at intervals along the axial direction of the main shaft 1. This allows a certain number of rotating components to be set at corresponding intervals according to the actual length of the pipe, so that the rotating components can clean the pipe more comprehensively and reduce pipe blockage.

[0047] The specific implementation process is as follows: After the pipeline is installed, water 8 is filled into the gap between the elastic wall 6 and the rigid pipe 7 to ensure that the pressure exerted by the water 8 on both sides of the elastic wall 6 is balanced when the water flows through.

[0048] In use, the self-cleaning water supply pipe of the present invention has a fast internal water flow rate. The blade 3 rotates around the main shaft 1 under the action of the water flow, thereby driving the protrusion 5 to rotate and continuously impact the smooth elastic wall 6, forming vibration. This causes any impurities or foreign objects that may be attached or deposited to be bounced up and carried out of the pipe with the water flow, thus preventing them from clogging the pipe.

[0049] This invention can minimize the possibility of impurities and foreign objects adhering inside the pipe without consuming additional energy, thereby reducing the risk of pipe blockage and thus reducing maintenance costs.

[0050] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
