Description

Technical Field

[0001] This invention belongs to the technical field of pipeline dredging equipment, and specifically relates to an ecological dredging device for urban pipeline networks. Background Technology

[0002] Urban underground pipeline systems play a crucial role in urban life and production, including flood control, drainage, and sewage disposal. In recent years, heavy rains have also posed a significant challenge to underground pipeline projects in municipal engineering construction in various cities. Typically, in public infrastructure construction, rainwater and sewage discharge are facilitated by complex underground drainage pipeline systems. Over long-term use, foreign matter accumulates within these underground drainage pipes.

[0003] A search revealed that Chinese Patent Publication No. CN213834728U, authorized on July 30, 2021, discloses an ecological dredging mechanism for urban pipe networks, comprising several hanging devices and a dispensing device for dispensing bacterial solution. The hanging devices include hooks that attach to the well edge, the hooks being used to hang the dispensing devices, and an adjustment device installed between the dispensing devices and the hooks to adjust the distance between the hanging devices. In this invention, the dispensing device for dispensing bacterial solution is suspended inside the drainage well via the hanging devices. Additionally, a cover is installed on the hanging device, which can be used as a temporary manhole cover without obstructing vehicle traffic. The dispensing device for dispensing bacterial solution is equipped with a driving device, which controls the sealing element to move along the connecting opening into the inner cavity of the connecting pipe, thereby allowing the bacterial solution in the dispensing device to be discharged intermittently. The adjustment device can adjust the distance between the hanging devices according to the size of different well openings to suit different well openings.

[0004] However, the equipment still has the following defects: although it can discharge the bacterial liquid in the dosing device intermittently, it cannot evenly spray the biological sludge removal agent on the sludge at different locations on the inner wall of the drainage pipe network. Moreover, the intermittent discharge of the bacterial liquid makes it impossible to effectively collect and separate the sewage in the sludge after it falls off, which easily leads to the phenomenon that the bacterial liquid and sewage are not conducive to recycling and treatment. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an ecological dredging device for urban pipe networks, comprising a bacterial solution dispensing component. A drainage pipe network is attached to the top edge of the bacterial solution dispensing component.

[0006] Furthermore, the bacterial liquid dispensing component includes a bacterial liquid storage tube; the bottom end of the bacterial liquid storage tube is a closed structure, and a handle is fixedly connected to the top of the bacterial liquid storage tube near the opening.

[0007] Furthermore, the outer wall of the lower limit plate is provided with two sets of guide grooves, and the inner walls of the two sets of guide grooves are sleeved on the outside of the steel wire rope. The two sets of guide grooves are rectangular structures, and the inner walls of the two sets of guide grooves are rolledly connected with several sets of balls, and the several sets of balls are in close contact with the outer wall of the steel wire rope.

[0008] Furthermore, the hanging mechanism includes a telescopic rod; one end of the telescopic rod is fixedly connected to the outer wall of the bacterial liquid storage tube, a screw is threaded onto the outer wall of the telescopic rod, and a right-angle metal piece is fixedly connected to the top of the telescopic rod and the side away from the screw. A first positioning post and a second positioning post are fixedly connected to the right-angle metal piece. The first positioning post is fitted and connected to the inner wall of the drainage pipe network, and the second positioning post is fitted and connected to the top of the drainage pipe network.

[0009] Furthermore, the sludge flushing assembly includes a linkage plate; a liquid collection shell is provided on the top of the linkage plate, and an air collection shell is provided on the bottom of the linkage plate. The air collection shell and the liquid collection shell are symmetrically arranged with the central axis of the linkage plate as the center. An elastic threaded tube connects the top of the liquid collection shell and the bottom of the bacterial liquid storage tube, and the bottom of the elastic threaded tube is rotatably connected to the top of the liquid collection shell.

[0010] Furthermore, several sets of high-pressure water nozzles are embedded in the outer wall of the liquid collection shell, and several sets of high-pressure air nozzles are embedded in the outer wall of the air collection shell. An adjustment groove is provided at the center of the central axis of the linkage plate, and a linkage rod is rotatably connected to the inner wall of the adjustment groove. The top end of the linkage rod is fixedly connected to the bottom end of the liquid collection shell, and the bottom end of the linkage rod is fixedly connected to the top end of the air collection shell.

[0011] Furthermore, a second positioning gear is fixedly connected to the center of the central axis of the linkage rod, a second driving gear is meshed with one side of the second positioning gear, the top of the second driving gear is drivenly connected to the output end of a stepper motor, and the side of the stepper motor away from the output end is fixedly connected to the top of the inner wall of the adjustment groove.

[0012] Furthermore, the outer wall of the linkage plate is provided with two sets of guide grooves, which are symmetrically arranged with the central axis of the linkage rod as the center. The inner wall of each set of guide grooves is rotatably connected to two sets of convex wheels. The two sets of convex wheels are rolled and attached to the outer wall of the steel wire rope.

[0013] Furthermore, the wastewater separation component includes a wastewater collection box; the top of the wastewater collection box is provided with a sludge guiding mechanism, and the sludge guiding mechanism is funnel-shaped; two sets of hanging rope locking parts are fixedly connected to the inner wall of the wastewater collection box.

[0014] Furthermore, both sets of the suspension rope locking components are threadedly fastened to the other end of the steel wire suspension rope, and the inner wall of the sewage collection box is movably connected with two sets of perforated plates, and the two sets of perforated plates are rotatably connected with hinge components.

[0015] The beneficial effects of this invention are:

[0016] 1. The bacterial solution dispensing component is adjusted to fit drainage pipe networks of different diameters, allowing it to be attached to the top of the network. A sludge flushing component is rolled and attached to different positions on two sets of steel wire ropes. During the lifting and lowering process, the bacterial solution from the dispensing component is evenly sprayed onto different positions on the inner wall of the drainage pipe network. High-pressure bacterial solution is used to flush the sludge from top to bottom along the inner wall of the network. The sludge and wastewater falling during the flushing process fall into a wastewater separation component. The wastewater separation component stores the sludge at the top and the wastewater at the bottom for separate treatment, effectively recycling the bacterial solution and wastewater.

[0017] 2. The biological sludge-removing agent in the bacterial liquid storage pipe is transferred to the collection shell through an elastic threaded tube. Several sets of high-pressure water nozzles spray the biological sludge-removing agent to make it contact the sludge on the inner wall of the drainage pipe network. Then, a micro air pump is used to deliver gas to the air collection shell, and several sets of high-pressure air nozzles blow the gas onto the surface of the sludge after the biological sludge-removing agent has been sprayed, in order to accelerate the penetration effect of the biological sludge-removing agent into the sludge.

[0018] 3. The bottom of the sewage collection box is extended to the bottom of the drainage pipe network via a steel wire rope. During the horizontal movement of the vertical rod driven by the output ends of several sets of miniature electric push rods, several sets of linkage balls pull the elastic rubber rings in different directions, causing the tops of several sets of sludge guide plates to move towards one side of the inner wall of the drainage pipe network. This causes the top of the sludge guiding mechanism to unfold in a funnel shape. The sludge and sewage that fall off the inner wall of the drainage pipe network after being flushed are collected by several sets of sludge guide plates and elastic bandages. The fallen sludge is then separated by a perforated plate, causing the sludge to accumulate on the top of the perforated plate and the sewage to be stored at the bottom of the perforated plate. This facilitates the drying of the sludge after the ecological treatment of the inner wall of the drainage pipe network.

[0019] 4. The output of the servo motor drives the first drive gear to rotate, and the first positioning gear, which meshes with the first drive gear, drives the storage cylinder to rotate synchronously. This is used to wind the two sets of steel wire ropes onto the storage cylinder. The ball bearings in different directions in the guide groove can roll and position the steel wire ropes during the winding process, improving the smoothness of the upward lifting of the sewage separation component after use. The ecological dredging device can then be easily recycled by pulling the handle.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0037] This invention provides an ecological dredging device for urban pipe networks, including a bacterial solution dispensing component 2; for example, such as... Figure 1 and Figure 2 As shown.

[0038] The top edge of the bacterial liquid dispensing component 2 is attached to a drainage pipe network 1.

A sewage separation component for collecting sludge that falls from the inner wall of the drainage pipe network 1 is fixedly connected to the bottom of the two sets of steel wire ropes 3.

[0039] Specifically, the bacterial solution dispensing component 2 is adjusted to fit drainage pipe networks 1 of different diameters, so that the bacterial solution dispensing component 2 is attached to the top of the drainage pipe network 1, and is attached to the sludge flushing component 4 at different positions of the two sets of steel wire ropes 3 by rolling.

[0043] The hanging mechanism 23 includes a telescopic rod 231; for example, such as Figure 6 As shown.

[0044] One end of the telescopic rod 231 is fixedly connected to the outer wall of the bacterial liquid storage tube 21. A screw 232 is threaded onto the outer wall of the telescopic rod 231. A right-angle metal piece 233 is fixedly connected to the top of the telescopic rod 231 and the side away from the screw 232.

[0045] The sludge flushing assembly 4 includes a linkage plate 41; for example, such as Figure 7 , Figure 8 and Figure 9 As shown.

[0046] The top of the linkage plate 41 is provided with a liquid collection shell 42, and the bottom of the linkage plate 41 is provided with an air collection shell 44. The air collection shell 44 and the liquid collection shell 42 are symmetrically arranged about the central axis of the linkage plate 41. The top of the liquid collection shell 42 is connected to the bottom of the bacterial liquid storage pipe 21 by an elastic threaded pipe 43, and the bottom of the elastic threaded pipe 43 is rotatably connected to the top of the liquid collection shell 42. Several sets of high-pressure water nozzles 45 are embedded in the outer wall of the liquid collection shell 42, and several sets of high-pressure air nozzles 46 are embedded in the outer wall of the air collection shell 44.

Two sets of guide grooves 412 are opened on the outer wall of the linkage plate 41. The two sets of guide grooves 412 are symmetrically arranged with the central axis of the linkage rod 48 as the center. Two sets of convex wheels 413 are rotatably connected to the inner wall of each set of guide grooves 412. The two sets of convex wheels 413 are rolled and attached to the outer wall of the steel wire rope 3. A micro motor is drivenly connected to one end of each set of convex wheels 413. The side of the micro motor away from the output end is embedded in the inner wall of the guide groove 412. A micro air pump 414 is provided at the bottom of the air collecting housing 44.

[0047] Furthermore, a bearing is embedded in the top of the liquid collection housing 42, and the interior of the bearing is fixedly connected to the bottom end of the elastic threaded tube 43.

[0048] The wastewater separation component 5 includes a wastewater collection box 52; for example, such as Figure 10 and Figure 11 As shown.

[0049] The top of the sewage collection box 52 is provided with a sludge guiding mechanism 51, which is funnel-shaped. The inner wall of the sewage collection box 52 is fixedly connected with two sets of suspension rope locking parts 53. Both sets of suspension rope locking parts 53 are threadedly fastened to the other end of the steel wire suspension rope 3. The inner wall of the sewage collection box 52 is movably connected with two sets of perforated plates 54, and the two sets of perforated plates 54 are rotatably connected with a hinge part 55.

[0050] Furthermore, a drain valve is also provided on one side wall of the sewage collection box 52.

[0051] The sludge guiding mechanism 51 includes an elastic rubber ring 511 and a metal positioning ring 517; for example, such as Figure 12 and Figure 13 As shown.

[0052] Several sets of sludge guide plates 512 are embedded in the elastic rubber ring 511, and elastic bandages 513 are provided between the sets of sludge guide plates 512. Several sets of linkage balls 514 are also embedded in the elastic rubber ring 511. The bottom of each set of linkage balls 514 is fixedly connected to a vertical rod 515. The outer wall of the vertical rod 515 is drivenly connected to the output end of a miniature electric push rod 516. The bottom of each set of sludge guide plates 512 is connected through a metal positioning ring 517. The outer wall of the metal positioning ring 517 is fixedly connected to several sets of U-shaped metal parts 518, and the sets of U-shaped metal parts 518 are located between every two sets of sludge guide plates 512. The sets of U-shaped metal parts are fixedly connected to the outer wall of the sewage collection box 52. The sets of miniature electric push rods 516 are fixedly connected to the inner wall of the sewage collection box 52, and the output ends of the sets of miniature electric push rods 516 penetrate through the outer wall of the sewage collection box 52.

[0053] Specifically, the top opening of the bacterial liquid storage pipe 21 is used to add biological sludge-removing bacterial agent. After the first positioning column 234 is adjusted to fit and connected to the inner wall of the drainage pipe network 1 by the telescopic rod 231, the adjusted length of the telescopic rod 231 is locked by rotating the screw 232. This allows several sets of first positioning columns 234 and second positioning columns 235 to fit and connect to different positions on the top and inner wall of the drainage pipe network 1, so that the sludge removal device is in a state ready for sludge removal after installation.

[0054] The elastic threaded tube 43 is used to transfer the biological sludge-removing agent in the bacterial liquid storage tube 21 to the liquid collection shell 42, so that several sets of high-pressure water nozzles 45 spray the biological sludge-removing agent, so that the biological sludge-removing agent comes into contact with the sludge on the inner wall of the drainage pipe network 1. Then, the micro air pump 414 is used to transport the gas to the air collection shell 44, so that several sets of high-pressure air nozzles 46 blow the gas on the surface of the sludge after the biological sludge-removing agent has been sprayed, so as to accelerate the penetration effect of the biological sludge-removing agent on the sludge.

[0055] The output end of the stepper motor 411 drives the second drive gear 410 to rotate, which drives the meshing second positioning gear 49 to rotate synchronously, so that the liquid collection housing 42 and the air collection housing 44 rotate around the second positioning gear 49. The connection between the top of the liquid collection housing 42 and the elastic threaded tube 43 is a rotatable connection, so that the liquid collection housing 42 will not be entangled with the elastic threaded tube 43 during the rotation of the liquid collection housing 42. Furthermore, several sets of high-pressure water nozzles 45 and high-pressure air nozzles 46 can evenly spray liquid and gas onto different positions on the inner wall of the drainage pipe network 1. Then, the output end of the micro motor drives the convex wheel 413 to rotate, so that the convex structure of every two sets of convex wheels 413 rolls and rubs against the steel wire rope 3, which is used to move the linkage plate 41 to different positions of the steel wire rope 3, so that several sets of high-pressure water nozzles 45 and high-pressure air nozzles 46 can wash the sludge from top to bottom on the inner wall of the drainage pipe network 1.

[0056] The bottom of the sewage collection box 52 extends to the bottom of the drainage pipe network 1 via a steel wire rope 3. During the horizontal movement of the vertical rod 515 driven by the output ends of several sets of micro electric push rods 516, several sets of linkage balls 514 pull the elastic rubber ring 511 in different directions, causing the tops of several sets of sludge guide plates 512 to move closer to one side of the inner wall of the drainage pipe network 1. This causes the top of the sludge guide mechanism 51 to unfold in a funnel shape. The sludge and sewage that fall off after rinsing the inner wall of the drainage pipe network 1 are collected by several sets of sludge guide plates 512 and elastic bandages 513. The fallen sludge is separated by a perforated plate 54, so that the sludge accumulates on the top of the perforated plate 54 and the sewage is stored at the bottom of the perforated plate 54. This is beneficial for the drying of the sludge after the ecological treatment of the inner wall of the drainage pipe network 1.

[0057] The output end of the servo motor drives the first drive gear 28 to rotate, and the first positioning gear 27, which meshes with the first drive gear 28, drives the storage cylinder 26 to rotate synchronously. This is used to wind the two sets of steel wire ropes 3 onto the storage cylinder 26. Furthermore, the ball bearings 210 in different directions in the guide groove 29 can roll and position the steel wire ropes 3 during the winding process, thereby improving the smoothness of the upward lifting of the sewage separation component 5 after use. Then, the ecological dredging device can be easily recycled by pulling the handle 22.

[0058] The working principle of an ecological dredging device for urban pipe networks proposed in this invention is as follows:

[0059] The biological sludge-removing agent is added through the top opening of the bacterial liquid storage pipe 21. After the first positioning column 234 is adjusted to fit and connect to the inner wall of the drainage pipe network 1 by the telescopic rod 231, the adjusted length of the telescopic rod 231 is locked by rotating the screw 232. This allows several sets of first positioning columns 234 and second positioning columns 235 to fit and connect to different positions on the top and inner wall of the drainage pipe network 1, so that the sludge removal device is in the state of being ready to remove sludge after installation.

[0060] The biological sludge-removing agent in the bacterial liquid storage pipe 21 is transferred to the liquid collection shell 42 through the elastic threaded tube 43, so that several sets of high-pressure water nozzles 45 spray the biological sludge-removing agent to contact the sludge on the inner wall of the drainage pipe network 1. Then, the micro air pump 414 delivers gas to the air collection shell 44, so that several sets of high-pressure air nozzles 46 blow the gas on the surface of the sludge after the biological sludge-removing agent has been sprayed, in order to accelerate the penetration effect of the biological sludge-removing agent on the sludge.

[0061] The output of the stepper motor 411 drives the second drive gear 410 to rotate, which in turn drives the meshing second positioning gear 49 to rotate synchronously. This causes the liquid collection housing 42 and the air collection housing 44 to rotate around the second positioning gear 49. The connection between the top of the liquid collection housing 42 and the elastic threaded tube 43 is a rotatable connection, which will not cause entanglement with the elastic threaded tube 43 during the rotation of the liquid collection housing 42. Furthermore, several sets of high-pressure water nozzles 45 and high-pressure air nozzles 46 can evenly spray liquid and gas onto different positions on the inner wall of the drainage pipe network 1. Then, the output of the micro motor drives the convex wheel 413 to rotate, so that the convex structure of every two sets of convex wheels 413 rolls and rubs against the steel wire rope 3. This allows the linkage plate 41 to move to different positions on the steel wire rope 3, achieving the effect of several sets of high-pressure water nozzles 45 and high-pressure air nozzles 46 flushing the sludge from top to bottom on the inner wall of the drainage pipe network 1.

[0062] The bottom of the sewage collection box 52 is extended to the bottom of the drainage pipe network 1 by the steel wire rope 3. During the horizontal movement of the vertical rod 515 driven by the output end of several sets of micro electric push rods 516, several sets of linkage balls 514 pull the elastic rubber ring 511 in different directions, causing the top of several sets of sludge guide plates 512 to move closer to one side of the inner wall of the drainage pipe network 1. The top of the sludge guide mechanism 51 unfolds in a funnel shape. The sludge and sewage that fall off after the inner wall of the drainage pipe network 1 is washed by several sets of sludge guide plates 512 and elastic bandages 513. The fallen sludge is separated by the perforated plate 54, so that the sludge accumulates on the top of the perforated plate 54 and the sewage is stored at the bottom of the perforated plate 54. This is conducive to the drying of the sludge after the ecological treatment of the inner wall of the drainage pipe network 1.

[0063] The output of the servo motor drives the first drive gear 28 to rotate, which in turn drives the first positioning gear 27, which meshes with the first drive gear 28, to rotate the storage cylinder 26 synchronously. This is used to wind the two sets of steel wire ropes 3 onto the storage cylinder 26. Furthermore, the ball bearings 210 in different directions within the guide groove 29 can roll and position the steel wire ropes 3 during the winding process, improving the smoothness of the upward lifting of the sewage separation component 5 after use. The ecological dredging device can then be easily recycled by pulling the handle 22.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
