Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically a self-cleaning pipeline anti-siltation structure. Background Technology

[0002] Sewage pipe networks are an important component of urban drainage systems. The sewage collection and treatment system consists of two main parts: the sewage pipe network and the sewage treatment system. The main sources of sewage pipe networks are untreated domestic sewage and industrial wastewater. With urban and social development and the intensification of human activities, the phenomenon of siltation and blockage in the drainage pipe networks of some cities is becoming increasingly serious.

[0003] The sources of sediment are twofold: first, surface particulate matter accumulated on various urban catchment surfaces during the dry season, which is washed into the sewage network through storm drains by rainwater; second, suspended particulate matter deposited within the sewage network itself. The former mainly consists of large inorganic particles, while the sediment in the sewage network is primarily composed of organic pollutants, mainly from domestic sewage. It comprises organic matter, non-cohesive materials (such as fine sand), cohesive materials (such as clay, silt, and sediment), and gravel.

[0004] Under weak hydrodynamic conditions, pollutants in the existing pipe network will deposit at the bottom of the pipe network during sewage transportation, forming pipe network sediments. The sediments reduce the cross-sectional area of ​​the pipe network, increase water flow resistance, and weaken the flow capacity. In turn, this further aggravates the siltation of the pipe network, weakens the hydrodynamic conditions, and leads to the accumulation of large amounts of black and odorous sediments, sewage overflow during rainy weather, and even the release of harmful gases. These phenomena are caused by pipe network siltation and blockage under weak hydrodynamic conditions.

[0005] Therefore, a self-cleaning anti-siltation structure for pipeline networks is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model addresses the problem that, under weak hydrodynamic conditions, pollutants in sewage pipe networks accumulate at the bottom of the network during sewage transport, forming deposits. These deposits reduce the cross-sectional area of ​​the pipe network, increase water flow resistance, and weaken flow capacity. This, in turn, further exacerbates siltation in the pipe network itself, weakens hydrodynamic conditions, and leads to the accumulation of large amounts of black and odorous sediments, sewage overflow during rainy weather, and even the release of harmful gases. These phenomena are all caused by siltation and blockage of the pipe network under weak hydrodynamic conditions.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The self-cleaning anti-siltation structure of the pipe network of this utility model includes a pipe network body, a water flow disturbance component is installed inside the pipe network body, and an installation and fixing component is connected to the outer wall of the water flow disturbance component; the water flow disturbance component includes a fixed ring, a movable ring, and a turbulence block, the outer wall of the fixed ring is provided with an annular guide rail, the movable ring is slidably connected to the annular guide rail through a slider, and a turbulence block is fixedly connected to the side of the movable ring.

[0008] Preferably, three turbulence blocks are arranged at equal angles to the bottom of the fixed ring, and the shape of the turbulence blocks is streamlined.

[0009] Preferably, the mounting and fixing assembly includes a base, a lead screw, a rotating shaft, a fixing baffle, and fixing holes. The base is fixed to both ends or the inner wall of the fixing ring. The lead screw passes through the base and is connected to one end of the rotating shaft. The other end of the rotating shaft is connected to the fixing baffle. The fixing baffle has fixing holes inside. When the lead screw is adjusted, it only moves inside the fixing ring or at both ends and does not contact the movable ring.

[0010] Preferably, the lead screw forms a rotating structure with the fixed baffle via a rotating shaft, and the lead screw is threadedly connected to the base.

[0011] The advantages of this utility model are:

[0012] 1. This utility model incorporates a water flow disturbance component. Three streamlined turbulence blocks are distributed at equal angles around the bottom of the fixed ring, forming a symmetrical disturbance structure. When water flows through, velocity and pressure differences are generated upstream and downstream of the turbulence blocks, forcing the water to form transverse circulation and longitudinal vortices within the pipe cross-section. This breaks the low-dynamic state of "layered flow" in traditional pipes, significantly enhancing the scouring force of the water on the silt at the bottom of the pipe. The movable ring is slidably connected to the annular guide rail on the outer wall of the fixed ring via a slider, allowing the turbulence blocks to move radially within a range of ±30°. During installation, the distance between the turbulence blocks and the pipe wall can be manually adjusted according to the pipe's inner diameter to match the disturbance effect with the pipe size, avoiding "water flow short circuit" or "disturbance blind zone" problems caused by the fixed installation of the turbulence blocks. The fixing seat and screw are moved from the outside of the movable ring to the inner wall or both ends of the fixed ring, forming an embedded fixing structure. During adjustment, the lead screw moves axially only inside the fixed ring, completely separating from the sliding path of the moving ring, thus eliminating the mechanical interference problem of "fixed components blocking the moving ring" in traditional designs.

[0013] 2. This utility model, by incorporating a mounting and fixing assembly, with the base fixed to both ends or the inner wall of the fixed ring, forms a radially inner fixing mode for the pipeline, completely detaching the lead screw, rotating shaft, and other transmission components from the sliding path of the movable ring. Compared to traditional external fixing methods, this structure avoids spatial overlap and interference between the fixing assembly and the movable ring, ensuring that the movable ring can slide freely along the annular guide rail and directly engage with the internal thread of the base, resulting in a short and concentrated force transmission path (transmission efficiency ≥95%). When the lead screw is rotated, the axial thrust is evenly transmitted to the fixed baffle through the rotating shaft, causing the fixed baffle to form a surface contact fixing with the inner wall of the pipeline, avoiding the stress concentration problem caused by traditional point contact fixing. The lead screw and the fixed baffle form a rotating structure through the rotating shaft. During adjustment, the lead screw only moves axially, and the fixed baffle synchronously generates radial displacement, while the sliding adjustment of the movable ring needs to be performed independently after the fixing assembly is installed. This step-by-step adjustment mode ensures that the rotational movement of the lead screw during the fixing process will not cause any disturbance to the movable ring, avoiding the "fixed force interfering with the positioning of the flow disturbance mechanism" problem caused by traditional synchronous adjustment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Example 1

[0021] Please see Figures 1 to 3 As shown, a self-cleaning anti-siltation structure for a pipe network includes a pipe network body 1. A water flow disturbance component 2 is installed inside the pipe network body 1, and a mounting and fixing component 3 is connected to the outer wall of the water flow disturbance component 2. The water flow disturbance component 2 includes a fixed ring 201, a movable ring 202, and turbulence blocks 203. The outer wall of the fixed ring 201 is provided with an annular guide rail. The movable ring 202 is slidably connected to the annular guide rail via a slider, and turbulence blocks 203 are fixedly connected to the side of the movable ring 202. Three turbulence blocks 203 are arranged at equal angles to the bottom of the fixed ring 201, and the shape of the turbulence blocks 203 is streamlined. When water flows through the inside of the pipe network body 1, the turbulence blocks 203 will create a velocity difference between the upper and lower parts of the water flow, thereby improving the weak hydrodynamic characteristics within the pipe network body 1. Furthermore, by reconstructing the dynamics, it reduces the accumulation of particulate matter within the pipe network body 1, fundamentally solving the problem of sewage pipe siltation under weak or even extremely weak hydrodynamic conditions.

[0022] Please see Figures 1 to 3 As shown, a self-cleaning pipe network anti-siltation structure includes an installation and fixing component 3, comprising a base 301, a lead screw 302, a rotating shaft 303, a fixing baffle 304, and a fixing hole 305. The lead screw 302 is internally threaded onto the base 301, and the rotating shaft 303 is mounted on one end of the lead screw 302. The fixing baffle 304 is connected to the other end of the rotating shaft 303, and the fixing hole 305 is provided inside the fixing baffle 304. The installation and fixing component 3 allows the device to be installed in pipe network bodies 1 with different inner diameters, increasing the device's practicality. In terms of usability, the lead screw 302 forms a rotating structure with the fixed baffle 304 via the rotating shaft 303, and the lead screw 302 is threadedly connected to the base 301. This allows the device to be securely installed in the water pipe, preventing the water flow from washing it away and thus avoiding the situation where the silt in the water pipe cannot be reduced. Furthermore, the distance between the fixed baffle 304 and the water flow disturbance connection assembly can be controlled by turning the lead screw 302, allowing the device to be installed in the pipe network body 1 with different inner diameters, thus increasing the practicality of the device.

[0023] Working principle: First, place the device in the pipeline body 1. Then, turn the screw 302. The screw 302 will rotate relative to the fixed baffle 304 through the rotating shaft 303. This can adjust the distance between the fixed baffle 304 and the fixed ring 201, so that the fixed baffle 304 can be tightly attached to the inner wall of the pipeline body 1. The device is installed on the inner wall of the pipeline body 1 by bolts and fixing holes 305.

[0024] Next, when water flows through the main body of the pipe network 1, the water flows from the lower part of the turbulence block 203 to the upper part. When the upper part of the water flows over the upper part of the turbulence block 203, the unit volume of the water becomes smaller, and the flow velocity of the water increases. After passing through multiple sets of turbulence blocks 203, the fast-flowing water will wash away the silt accumulated in the main body of the pipe network 1 after passing through the turbulence block 203, thereby achieving the purpose of cleaning the silt in the main body of the pipe network 1.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
