Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a water pipe structure for preventing siltation. Background Technology

[0002] In urban and rural water supply and drainage systems, structural design flaws are commonly found at the connection points of both water supply pipelines conveying clean water and drainage networks discharging domestic sewage. When these pipe fittings are assembled using traditional methods such as threaded tightening, rubber ring sealing, or socket bonding, the annular gaps, stepped surfaces, or uneven interfaces formed at the joints objectively constitute obstructions to fluid movement. When water flows through these irregular structures, local turbulence and vortices easily form at the connection points, causing suspended matter in the water to undergo inertial deposition or adsorption on the pipe wall in this turbulent flow field, ultimately reducing the effective diameter of the pipe.

[0003] Pipe blockages reduce water flow capacity, leading to insufficient water pressure at the end of the network and potential water outages in high-rise buildings during peak water usage periods. Poor sewage discharge can cause backflow into manholes and road overflows, posing hygiene hazards. Traditional pipe connections have complex geometries, making it difficult to thoroughly remove deposits using conventional high-pressure flushing. This often necessitates cutting the pipe for manual cleaning, increasing maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a water pipe structure that prevents siltation, so as to solve the problem of pipe blockage caused by impurities adhering to the pipe wall.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A water pipe structure for preventing sludge buildup includes: a first pipe fitting, a second pipe fitting, and a third pipe fitting, wherein both ends of the first pipe fitting are respectively inserted into the second pipe fitting and the third pipe fitting; a first cleaning assembly, rotatably installed inside the first pipe fitting, with at least a portion of the first cleaning assembly abutting against the inner wall of the first pipe fitting to clean sludge buildup on the inner wall of the first pipe fitting; a second cleaning assembly, rotatably installed inside the second pipe fitting, with at least a portion of the second cleaning assembly abutting against the inner wall of the second pipe fitting to clean sludge buildup on the inner wall of the second pipe fitting; and a third cleaning assembly, rotatably installed inside the third pipe fitting, with at least a portion of the third cleaning assembly abutting against the inner wall of the third pipe fitting to clean sludge buildup on the inner wall of the third pipe fitting; the first cleaning assembly, the second cleaning assembly, and the third cleaning assembly are connected and can rotate simultaneously.

[0007] Based on the aforementioned technical means, this utility model, by respectively assembling a first cleaning component, a second cleaning component, and a third cleaning component in the first, second, and third pipe fittings, covers the inner wall of the entire pipeline system. The three cleaning components rotate synchronously, continuously scraping away impurities adhering to the pipe wall, preventing long-term deposition of impurities and the formation of stubborn scale, thus fundamentally solving the problem of pipe blockage. Continuous cleaning of the pipe wall reduces inner wall roughness, lowers water flow resistance, improves pipeline transport efficiency, and saves energy.

[0008] The three-pipe plug-in design of this utility model facilitates quick disassembly, and allows for the individual replacement of worn cleaning components or pipes, thus extending the overall service life of the pipeline.

[0009] Furthermore, the first cleaning component includes a first rotating shaft and a first scraper. The first rotating shaft and the first scraper are respectively arranged along the axial direction of the first pipe. The first scraper is connected to the first rotating shaft and abuts against the inner wall of the first pipe. The rotation of the first rotating shaft can drive the first scraper to scrape off the sludge accumulated on the inner wall of the first pipe.

[0010] Based on the aforementioned technical means, this utility model utilizes a first scraper that directly abuts against the inner wall of the first pipe fitting, achieving continuous rotational scraping under the drive of a first rotating shaft. This actively removes deposits adhering to the inner wall of the pipe, preventing pipe diameter reduction or complete blockage caused by long-term impurity deposition. The first rotating shaft and the first scraper are arranged axially along the pipe fitting, ensuring that the scraper covers the entire inner wall cross-section of the pipe fitting during rotation. This eliminates blind spots caused by the structural limitations of traditional cleaning tools, achieving 360° anti-dead-angle anti-deposit. Simultaneously, the axially designed rotating shaft aligns with the water flow direction, effectively reducing fluid resistance during scraper rotation.

[0011] Furthermore, the first cleaning component also includes a first blade, which is helically fixed on the first rotating shaft. The first blade can drive the first rotating shaft to rotate under the impact of water flow. The first scraper is connected to the first scraper through the first blade.

[0012] According to the above-mentioned technical means, the spiral structure makes the contact area between the first blade and the water flow spirally distributed, which can efficiently convert the linear kinetic energy of the water flow into rotational torque. When the propeller blade rotates, its spiral surface pushes the water flow to form an axial vortex. The vortex reacts on the blade surface, thereby generating a continuous self-driving pressurization effect, which can maintain stable rotation even at low flow rates.

[0013] Meanwhile, the right-hand / left-hand spiral structure of the propeller blades is compatible with both forward and reverse water flow. When the water flow direction changes, the blades can still maintain effective drive, avoiding jamming of the cleaning components.

[0014] Furthermore, the second pipe fitting is inserted into the first pipe fitting; the first cleaning assembly also includes a support frame, which is mounted around the inner wall of the first pipe fitting and abuts against the second pipe fitting; an annular groove is formed between the support frame and the inner wall of the first pipe fitting, and the end of the first scraper is movably mounted in the groove.

[0015] According to the above technical means, the support frame in this utility model has an L-shaped cross section. When it is installed around the inner wall of the first pipe, it can form an annular groove in the first pipe. The annular groove is used to place the end of the first scraper. The first scraper is limited to rotate in the groove, so that the first cleaning assembly can be supported in the first pipe.

[0016] Furthermore, the first cleaning component also includes a bearing, which includes an inner ring and an outer ring. The bearing is located on one side of the support frame, and the inner ring is connected to the support frame. The outer ring of the bearing is fixedly connected to the first scraper.

[0017] According to the above-mentioned technical means, the bearing realizes the relative movement between the inner and outer rings through the rolling elements, which transforms the sliding friction between the first scraper and the support frame into rolling friction, reduces the frictional resistance, and greatly improves the cleaning efficiency of the first scraper.

[0018] Furthermore, the first cleaning assembly also includes a second scraper connected to the first scraper, and the second scraper abuts against the side of the bearing away from the support frame.

[0019] Based on the aforementioned technical methods, silt deposits inside the pipeline easily adhere to the rolling elements or raceway surface of the bearing, leading to increased rotational resistance or even jamming. The second scraper continuously removes impurities from the bearing surface through physical contact, avoiding the risk of jamming caused by foreign object intrusion and ensuring the continuous operation of the cleaning assembly.

[0020] Furthermore, the first cleaning component also includes a third scraper, which is connected to the first scraper and is located between the bearing and the bearing, and the third scraper abuts against the bearing and the bearing respectively.

[0021] According to the above-mentioned technical means, the gap between bearings is a hidden area that is difficult to cover by traditional cleaning devices. The third scraper fills the blind spot through physical contact, preventing impurities from accumulating there and avoiding bearing failure due to local blockage.

[0022] Furthermore, the third pipe fitting is inserted into the first pipe fitting; the first cleaning assembly also includes a fourth scraper, which is connected to the first scraper and abuts against the third pipe fitting.

[0023] Based on the aforementioned technical means, the fourth scraper continuously cleans the joint gap between the third and first pipe fittings through physical contact, preventing the accumulation of mud, sand, and other substances, and avoiding flow attenuation or complete blockage due to narrow pipe openings. Pipe opening cleaning ensures unobstructed flow through the joint area, eliminating turbulence and pressure fluctuations caused by localized blockages, and guaranteeing flow balance between upstream and downstream pipe fittings.

[0024] Furthermore, the second cleaning component includes a second rotating shaft, a fifth scraper, and a second blade. The second rotating shaft is coaxially connected to the first rotating shaft. The second blade is helically fixed on the second rotating shaft. The fifth scraper is arranged axially along the second rotating shaft and connected to the second blade. The fifth scraper can abut against the inner wall of the second pipe.

[0025] Based on the above technical means, the spiral structure of the second blade ensures that the water flow impact force is efficiently converted into rotational torque; the second shaft is coaxially connected with the first shaft to form a rigid power transmission link, avoiding energy loss caused by shaft misalignment in traditional split structures; the fifth scraper is arranged axially and elastically abuts against the inner wall of the second pipe fitting, and adapts to the pipe diameter deformation through the centrifugal force generated by the rotation of the second blade, ensuring that the fifth scraper is in continuous contact with the pipe wall of the second pipe fitting, effectively removing hard scale and adhesive deposits.

[0026] Furthermore, the third cleaning component includes a third rotating shaft, a sixth scraper, and a third blade. The third rotating shaft is coaxially connected to the first rotating shaft. The third blade is helically fixed on the third rotating shaft. The sixth scraper is axially arranged along the third rotating shaft and connected to the third blade. The sixth scraper can abut against the inner wall of the third pipe.

[0027] Based on the above technical means, the spiral structure of the third blade ensures that the water flow impact force is efficiently converted into rotational torque; the third shaft is coaxially connected with the first shaft to form a rigid power transmission link, avoiding energy loss caused by shaft misalignment in traditional split structures; the sixth scraper is arranged axially and elastically abuts against the inner wall of the third pipe fitting, and adapts to the pipe diameter deformation through the centrifugal force generated by the rotation of the third blade, ensuring that the sixth scraper is in continuous contact with the pipe wall of the third pipe fitting, effectively removing hard scale and adhesive deposits.

[0028] The beneficial effects achieved by this utility model are:

[0029] This invention utilizes a first cleaning component, a second cleaning component, and a third cleaning component, respectively, installed in the first, second, and third pipe fittings. These components cover the entire inner wall of the pipeline system, and rotate synchronously to continuously scrape away impurities adhering to the pipe wall. This prevents long-term accumulation of impurities and the formation of stubborn scale, thus solving the problem of pipe blockage at its source. Continuous cleaning of the pipe wall reduces inner wall roughness, lowers water flow resistance, improves pipeline transport efficiency, and saves energy.

[0048] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1As shown, a water pipe structure for preventing siltation includes: a first pipe fitting 1, a second pipe fitting 2, and a third pipe fitting 3, wherein the two ends of the first pipe fitting 1 are respectively inserted into the second pipe fitting 2 and the third pipe fitting 3; a first cleaning component 4, which is rotatably installed inside the first pipe fitting 1, and at least a portion of the first cleaning component 4 abuts against the inner wall of the first pipe fitting 1 to clean siltation on the inner wall of the first pipe fitting 1; a second cleaning component 5, which is rotatably installed inside the second pipe fitting 2, and at least a portion of the second cleaning component 5 abuts against the inner wall of the second pipe fitting 2 to clean siltation on the inner wall of the second pipe fitting 2; and a third cleaning component 6, which is rotatably installed inside the third pipe fitting 3, and at least a portion of the third cleaning component 6 abuts against the inner wall of the third pipe fitting 3 to clean siltation on the inner wall of the third pipe fitting 3; the first cleaning component 4, the second cleaning component 5, and the third cleaning component 6 are connected and can rotate simultaneously.

[0050] In this embodiment, the first pipe fitting 1 is an intermediate connecting pipe, and the second pipe fitting 2 and the third pipe fitting 3 can be connected to the water supply system and the other pipe fitting 3 respectively, depending on actual needs; or one pipe fitting can be connected to the water supply system and the other pipe fitting 3 can be connected to the sewage treatment system.

[0051] This embodiment incorporates a first cleaning component 4, a second cleaning component 5, and a third cleaning component 6 in the first pipe fitting 1, the second pipe fitting 2, and the third pipe fitting 3, respectively. These components cover the entire inner wall of the pipeline system, and rotate synchronously to continuously scrape away impurities adhering to the pipe wall. This prevents long-term accumulation of impurities and the formation of stubborn scale, thus solving the pipe blockage problem at its source. Continuous cleaning of the pipe wall reduces inner wall roughness, lowers water flow resistance, improves pipeline transport efficiency, and saves energy.

[0052] In this embodiment, the three-pipe plug-in design facilitates quick disassembly, allowing for individual replacement of worn cleaning components or pipes, thus extending the overall pipeline service life.

[0053] The specific usage process is as follows:

[0054] The first pipe fitting 1 is inserted into the second pipe fitting 2 and the third pipe fitting 3 at both ends to form a complete pipeline system. At this time, the first cleaning component 4, the second cleaning component 5, and the third cleaning component 6 are pre-installed in the corresponding pipe fittings, and the three are linked together by a connecting shaft or gear structure.

[0055] Activation of the cleaning function: Method 1 (water flow driven, detailed water flow drive structure in this embodiment): When water flows into the second pipe fitting 2 or the third pipe fitting 3, the water flow impacts the second cleaning component 5 or the third cleaning component 6 (such as those containing propeller blades or turbine structures), causing the second cleaning component 5 or the third cleaning component 6 to rotate. This, in turn, causes the first cleaning component 4 and the other cleaning component to rotate synchronously through a linkage structure. Simultaneously, in complex water flow environments within the pipeline system, the first cleaning component 4 and the other cleaning component will also rotate independently under the influence of the water flow, thereby comprehensively improving cleaning efficiency.

[0056] Method 2 (External Power): If the water flow power is insufficient, the first cleaning component 4 can be driven by a micro motor or a manual crank, which in turn drives the entire cleaning component to rotate (the micro motor or manual crank can be installed outside the pipe fitting and sealed properly; or a waterproof setting can be implemented, and the micro motor can be installed inside the pipe fitting).

[0057] As the cleaning components rotate, their surfaces (bristles, scrapers, or spiral protrusions) continuously scrape the pipe walls, removing attached impurities (such as silt, algae, and rust) and mixing them into the water flow, which is then discharged from the pipe with the fluid. The three sets of cleaning components work synchronously to ensure that the inner walls of the first pipe fitting 1, the second pipe fitting 2, and the third pipe fitting 3 are cleaned in real time, preventing localized siltation.

[0058] When critical maintenance is required, stop the water flow, disassemble all pipe fittings and connections, and inspect the cleaning components for wear. If a cleaning component is dulled, replace the corresponding component individually; there is no need to replace the entire pipe. Clean any stubborn dirt remaining on the inner walls of the pipe fittings (if any), and reassemble to restore the anti-sludge function.

[0059] like Figure 1 As shown, the first cleaning component 4 includes a first rotating shaft 41 and a first scraper 42. The first rotating shaft 41 and the first scraper 42 are respectively arranged along the axial direction of the first pipe 1. The first scraper 42 is connected to the first rotating shaft 41 and abuts against the inner wall of the first pipe 1. The rotation of the first rotating shaft 41 can drive the first scraper 42 to scrape off the silt accumulated on the inner wall of the first pipe 1.

[0060] In this embodiment, the first scraper 42 directly abuts against the inner wall of the first pipe fitting 1, and under the drive of the first rotating shaft 41, it achieves continuous rotation and scraping. This actively removes deposits (such as silt, scale, biofilm, etc.) adhering to the inner wall of the pipe, preventing pipe diameter reduction or complete blockage caused by long-term accumulation of impurities. The first rotating shaft 41 and the first scraper 42 are arranged along the axial direction of the pipe fitting, ensuring that the first scraper 42 covers the entire inner wall cross section of the pipe fitting during rotation. This eliminates the cleaning blind spots caused by the structural limitations of traditional cleaning tools (such as unidirectional brush heads), achieving 360° anti-dead-angle anti-deposit. At the same time, the axially designed first rotating shaft 41 is consistent with the water flow direction, which can effectively reduce the resistance to the fluid when the first scraper 42 rotates.

[0061] In this preferred embodiment, the first scraper 42 flexibly contacts the pipe wall (e.g., using elastic materials such as rubber or nylon), which can adaptively adjust the contact pressure when the first pipe 1 deforms due to thermal expansion and contraction or external force, avoiding hard friction damage to the pipe wall and extending the service life of the pipeline.

[0062] like Figure 1 and Figure 5 As shown, the first cleaning component 4 also includes a first blade 43, which is spirally fixed on the first rotating shaft 41. The first blade 43 can drive the first rotating shaft 41 to rotate under the impact of water flow. The first scraper 42 is connected to the first scraper 42 through the first blade 43.

[0063] The spiral structure makes the contact area between the first blade 43 and the water flow spirally distributed, which can efficiently convert the linear kinetic energy of the water flow into rotational torque. When the propeller blade rotates, its spiral surface pushes the water flow to form an axial vortex. This vortex reacts on the blade surface, thereby generating a continuous self-driving pressurization effect, which can maintain stable rotation even at low flow rates.

[0064] Meanwhile, the right-hand / left-hand rotation structure of the propeller blades is compatible with both forward and reverse water flow. When the water flow direction changes (such as backflow caused by the start-up and shutdown of the pump station), the propeller blades can still maintain effective drive and avoid jamming of the cleaning components.

[0065] In this embodiment, the first blade 43 can adopt a segmented variable pitch design: the pitch is larger near the inlet end (e.g., P1 = 50mm), utilizing the impact of high-speed water flow to generate initial torque; the pitch gradually decreases near the outlet end (e.g., P2 = 30mm), increasing the outlet pressure by compressing the water flow, forming a "Venturi effect" to assist drive. The first blade 43 can also have its surface processed with biomimetic fish fin-like textured surfaces, such as a sharkskin drag-reducing structure, to reduce water flow separation and lower drive resistance through micro-vortex control.

[0066] It is easy to imagine that multiple sets of first blades 43 are set on the first shaft 41 to balance the axial thrust generated by a single propeller blade and reduce shaft vibration; when one set of blades is blocked by impurities, the others can still maintain basic driving capability.

[0067] like Figure 1 and Figure 3 As shown, the second pipe fitting 2 is inserted into the first pipe fitting 1; the first cleaning assembly 4 also includes a support frame 44, which is mounted around the inner wall of the first pipe fitting 1 and abuts against the second pipe fitting 2; an annular groove is formed between the support frame 44 and the inner wall of the first pipe fitting 1, and the end of the first scraper 42 is movably mounted in the groove.

[0068] In this embodiment, the support frame 44 has an L-shaped cross section. When it is installed around the inner wall of the first pipe 1, it can form an annular groove in the first pipe 1. The annular groove is used to place the end of the first scraper 42. The first scraper 42 is limited to rotate in the groove, so that the first cleaning assembly 4 can be supported in the first pipe 1.

[0069] In this embodiment, the support frame 44 can be multiple sets, such as... Figure 2 As shown, two support frames 44 are respectively provided at both ends of the first scraper 42 to effectively support the entire first cleaning component 4.

[0070] like Figure 1 and Figure 3 As shown, the first cleaning component 4 also includes a bearing 45, which includes an inner ring and an outer ring. The bearing 45 is located on one side of the support frame 44, and the inner ring is connected to the support frame 44. The outer ring of the bearing 45 is fixedly connected to the first scraper 42.

[0071] The bearing 45 achieves relative movement between the inner and outer rings through rolling elements (such as balls or rollers), converting the sliding friction between the first scraper 42 and the support frame 44 into rolling friction, reducing frictional resistance and greatly improving the cleaning efficiency of the first scraper 42.

[0072] like Figure 1 and Figure 3 As shown, the first cleaning assembly 4 also includes a second scraper 46, which is connected to the first scraper 42 and abuts against the side of the bearing 45 away from the support frame 44.

[0073] Debris inside the pipe can easily adhere to the rolling elements or raceway surface of the bearing 45, leading to increased rotational resistance or even jamming. The second scraper 46 continuously removes impurities from the surface of the bearing 45 through physical contact, avoiding the risk of jamming caused by foreign object intrusion and ensuring the continuous operation of the cleaning assembly.

[0074] like Figure 1 and Figure 3 As shown, the first cleaning component 4 also includes a third scraper 47, which is connected to the first scraper 42 and is located between the bearing 45 and the bearing 45. The third scraper 47 abuts against the bearing 45 and the bearing 45 respectively.

[0075] The gap between bearings 45 is a hidden area that is difficult to cover by traditional cleaning devices. The third scraper 47 fills the blind spot through physical contact, preventing impurities from accumulating there and avoiding the problem of bearings 45 not operating due to local blockage.

[0076] like Figure 1 and Figure 4As shown, the third pipe fitting 3 is inserted into the first pipe fitting 1; the first cleaning assembly 4 also includes a fourth scraper 48, which is connected to the first scraper 42 and abuts against the third pipe fitting 3.

[0077] The fourth scraper 48 continuously cleans the joint between the third fitting 3 and the first fitting 1 through physical contact, preventing the accumulation of mud, sand, and other substances, and avoiding flow attenuation or complete blockage due to narrow pipe openings. Pipe opening cleaning ensures that fluid passes through the joint area without obstruction, eliminates turbulence and pressure fluctuations caused by local blockages, and ensures flow balance between upstream and downstream fittings.

[0078] It should be noted that if both ends of the first scraper 42 are equipped with support frames 44, then the fourth scraper 48 is not required.

[0079] like Figure 1 As shown, the second cleaning assembly 5 includes a second rotating shaft 51, a fifth scraper 52, and a second blade 53. The second rotating shaft 51 is coaxially connected to the first rotating shaft 41. The second blade 53 is helically fixed on the second rotating shaft 51. The fifth scraper 52 is arranged axially along the second rotating shaft 51 and connected to the second blade 53. The fifth scraper 52 can abut against the inner wall of the second pipe 2.

[0080] The spiral structure of the second blade 53 ensures that the water flow impact force is efficiently converted into rotational torque; the second shaft 51 is coaxially connected with the first shaft 41 to form a rigid power transmission link, avoiding energy loss caused by shaft misalignment in traditional split structures (such as coupling friction and shaft wobble); the fifth scraper 52 is arranged axially and elastically abuts against the inner wall of the second pipe fitting 2. The centrifugal force generated by the rotation of the second blade 53 adapts to the pipe diameter deformation, ensuring that the fifth scraper 52 is in continuous contact with the pipe wall of the second pipe fitting 2, effectively removing hard scale and adhesive deposits.

[0081] like Figure 1 As shown, the third cleaning component 6 includes a third rotating shaft 61, a sixth scraper 62, and a third blade 63. The third rotating shaft 61 is coaxially connected to the first rotating shaft 41. The third blade 63 is spirally fixed on the third rotating shaft 61. The sixth scraper 62 is arranged axially along the third rotating shaft 61 and connected to the third blade 63. The sixth scraper 62 can abut against the inner wall of the third pipe 3.

[0082] The spiral structure of the third blade 63 ensures that the water flow impact force is efficiently converted into rotational torque; the third shaft 61 is coaxially connected with the first shaft 41 to form a rigid power transmission link, avoiding energy loss caused by shaft misalignment in traditional split structures (such as coupling friction and shaft runout); the sixth scraper 62 is arranged axially and elastically abuts against the inner wall of the third pipe fitting 3. The centrifugal force generated by the rotation of the third blade 63 adapts to the pipe diameter deformation, ensuring that the sixth scraper 62 is in continuous contact with the pipe wall of the third pipe fitting 3, effectively removing hard scale and adhesive deposits.

[0083] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
