Description

Technical Field

[0001] This invention relates to the field of pipeline dredging technology, and in particular to a municipal engineering pipeline drainage dredging device. Background Technology

[0002] During the use of municipal pipelines, impurities and plastics mixed in with sewage can accumulate inside the pipes. When too many impurities accumulate, it can easily cause blockages, leading to the growth of harmful substances and bacteria, which can severely pollute water resources and hinder environmental water management. Therefore, it is necessary to dredge the inside of the pipelines to ensure unobstructed flow.

[0003] Existing unblocking methods generally involve using high-pressure water jets to flush out silt from pipes. The process involves bringing a small vehicle capable of spraying high-pressure water to the site, inserting a nozzle into the pipe using a high-pressure water hose, and pushing the hose to move the nozzle forward, allowing the high-pressure water to disperse the accumulated silt and clear the blockage. However, this method is generally ineffective. When the blockage is heavy, involves multiple types of impurities, or is long, high-pressure water alone cannot achieve a satisfactory unblocking effect. Summary of the Invention

[0008] As a preferred embodiment of the present invention, a curved wheel ring is fixedly connected to the surface of the movable disc, a fixed frame is fixedly connected to the movable rod, a pulley that can roll along the curved wheel ring is fixedly connected to the fixed frame, an elastic telescopic member is fixedly connected to one end of the movable rod, a U-shaped connecting frame is fixedly connected to the unblocking nozzle, and the elastic telescopic member is fixedly connected to the connecting frame.

[0009] As a preferred embodiment of the present invention, the elastic telescopic member includes a rod cylinder and a rod body, a return spring is connected inside the rod cylinder, a limiting strip is provided on the surface of the rod body, and a limiting groove that cooperates with the limiting strip is provided on the inner wall of the rod cylinder.

[0010] As a preferred embodiment of the present invention, a spiral conveying blade is fixedly connected to the surface of the rotating tube, and the surface of the spiral conveying blade is provided with a clearance groove that cooperates with the crushing blade.

[0011] As a preferred embodiment of the present invention, a rotating shaft is rotatably connected inside the unblocking nozzle, one end of the rotating shaft is connected to a worm gear blade for increasing water pressure, a second driven gear is fixedly connected to the rotating shaft, and a second driving gear meshing with the second driven gear is fixedly connected to the rotating shaft.

[0012] As a preferred embodiment of the present invention, the unblocking nozzle is provided with annular spray holes, and a movable annular valve ring is connected inside the spray holes. The valve ring is fixedly connected to the fixing frame through a second support rod.

[0013] As a preferred embodiment of the present invention, the outer surface of the valve ring is provided with a conical structure, and the inner surface of the valve ring is provided with a sliding groove that is slidably connected to the connecting frame.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example

[0031] like Figures 1-9 As shown in the figure, this embodiment discloses a municipal engineering pipeline drainage dredging device, including a dredging nozzle 3, a water pipe 6 connected to the dredging nozzle 3, annular spray holes 18 on the dredging nozzle 3, a rotating pipe 1 rotatably connected to one end of the dredging nozzle 3, and a crushing component 2 for crushing blockages in the pipeline connected to the rotating pipe 1; the crushing component 2 crushes large blockages, making it easier for the dredging nozzle 3 to flush and dredge the blockages.

[0032] like Figures 2-5As shown, a rotating ring 108 is rotatably connected to the surface of the rotating pipe 1. The rotating ring 108 is fixedly connected to the unblocking nozzle 3 via a bracket 109, ensuring stable rotation of the rotating pipe 1. A spiral conveying blade 101 is fixedly connected to the surface of the rotating pipe 1. When the spiral conveying blade 101 rotates, it can drive the blockage forward, facilitating pipe unblocking. The pulverizing component 2 includes a moving rod 202, which is located inside the rotating pipe 1. The moving rod 202 can move back and forth inside the rotating pipe 1, and always remains stationary. A rotating ring 108 is rotatably connected to the surface of the moving rod 202. Several connecting rings 201 are connected to the rotating tube 1, and a gap is provided between the spiral conveying blade 101 and the rotating tube 1 to allow the connecting rings 201 to move. The surface of the rotating tube 1 has several sliding holes 102 that slidably engage with the connecting rings 201, with each connecting ring 201 corresponding to 3-4 sliding holes 102. A limiting block 204 is provided on the inner surface of the connecting ring 201 and slidably connected to the sliding hole 102. The surface of the moving rod 202 is rotatably connected to the limiting block 204. When the moving rod 202 moves, it can drive the connecting rings 201 to move along the sliding holes 102. The connecting ring 201 has multiple hinge seats 206 arranged radially on its surface. A hinge block 205 is rotatably connected to each hinge seat 206, and a crushing blade 203 is fixedly connected to each hinge block 205. A first connecting rod 208 connects adjacent connecting rings 201, with both ends of the first connecting rod 208 rotatably connected to the hinge block 205. The surface of the spiral conveying blade 101 has a clearance groove 103 that mates with the crushing blade 203, allowing the crushing blade 203 to be stored during use and preventing it from affecting the movement of the rotating tube 1. A movable moving disc is connected to the surface of the rotating tube 1. 104. The moving disk 104 is rotatably connected to the hinge block 205 on the nearest connecting ring 201 with the second connecting rod 5. The rotating tube 1 is equipped with a pushing mechanism 107, which can be an electric push rod. The pushing mechanism 107 is fixedly connected to the moving disk 104. The moving disk 104 is driven to move on the rotating tube 1 by the pushing mechanism 107, thereby controlling the unfolding and retraction of the crushing blade 203. When the crushing blade 203 is working, it is unfolded. When it is not working, it is retracted into the spiral conveying blade 101.

[0033] To control the reciprocating motion of the crushing component 2, a curved wheel ring 105 is fixedly connected to the surface of the moving disc 104. A fixed frame 209 is fixedly connected to the moving rod 202, and a pulley 210 that can roll along the curved wheel ring 105 is fixedly connected to the fixed frame 209. An elastic telescopic member 207 is fixedly connected to one end of the moving rod 202. A U-shaped connecting frame 11 is fixedly connected to the unblocking nozzle 3. The elastic telescopic member 207 is fixedly connected to the connecting frame 11. The elastic telescopic member 207 ensures that the pulley 210 always remains in contact with the curved wheel ring 105. When the rotating tube 1 rotates, it drives the crushing component 2 to rotate, crushing the blockage. The crushed blockage is then conveyed forward by the spiral conveying blades 101. When the rotating tube 1 rotates, it drives the curved wheel ring 105 to rotate. When the pulley 210 rotates on the surface of the curved wheel ring 105, it drives the moving rod 202 to move back and forth. The elastic telescopic component 207 continuously extends and retracts, thereby driving each connecting ring 201 to move back and forth on the surface of the rotating tube 1, which in turn drives the crushing blade 203 to move back and forth, crushing blockages at different locations to achieve a better crushing effect.

[0034] like Figure 6 As shown, the elastic telescopic member 207 includes a rod cylinder 2071 and a rod body 2072. A return spring 2073 is connected inside the rod cylinder 2071. A limiting strip 2075 is provided on the surface of the rod body 2072. A limiting groove 2074 that cooperates with the limiting strip 2075 is provided on the inner wall of the rod cylinder 2071. The return spring 2073 applies elastic force to the rod body 2072, thereby resetting the moving rod 202.

[0035] like Figure 1 and Figure 7 As shown, a movable annular valve ring 4 is connected inside the water spray hole 18. The valve ring 4 is fixedly connected to the fixing frame 209 via the second support rod 211. The outer surface of the valve ring 4 is provided with a conical structure 401, and the inner surface of the valve ring 4 is provided with a sliding groove 402 that is slidably connected to the connecting frame 11. When the crushing component 2 is working, the moving rod 202 moves back and forth, driving the valve ring 4 to move back and forth inside the water spray hole 18. Through the conical structure 401 on the outer surface of the valve ring 4, the size of the water spray hole 18 is continuously changed, and the direction of water spray is changed, so as to flush different positions in the pipeline and better flush away the blockage.

[0036] like Figures 8-9As shown, a support frame 16 is fixedly connected to the bottom of the unblocking nozzle 3, and a roller 17 is fixedly connected to the bottom of the support frame 16 to facilitate the movement of the unblocking nozzle 3. The support frame 16 supports the device and prevents the crushing component 2 from contacting the bottom of the pipe during operation. A motor 7 and a power supply 13 are installed on the outside of the unblocking nozzle 3. The power supply 13 supplies power to the motor 7. A rotating shaft 8 is connected to the motor 7, and a first drive gear 9 is connected to the rotating shaft 8. A first driven gear 106 that meshes with the first drive gear 9 is fixedly connected to the surface of the rotating tube 1. A rotatable part of the unblocking nozzle 3 is rotatably connected inside. A rotating shaft 14 has a worm gear blade 15 connected to one end to increase water pressure. A second driven gear 12 is fixedly connected to the rotating shaft 14, and a second driving gear 10 that meshes with the second driven gear 12 is fixedly connected to the rotating shaft 8. During operation, the motor 7 drives the first driving gear 9 and the second driving gear 10 to rotate. When the first driving gear 9 rotates, it drives the rotating tube 1 and the crushing component 2 to rotate. When the second driving gear 10 rotates, it drives the worm gear blade 15 to rotate, further increasing the water pressure in the unblocking nozzle 3, so that water is sprayed out from the spray hole 18 at high pressure, flushing away the blockage.

[0037] Working principle: When in use, the device is inserted into the pipe through the water pipe 6. The motor 7 is started, which drives the rotating pipe 1 and the crushing component 2 to rotate. When the rotating pipe 1 rotates, it drives the crushing component 2 to move back and forth. The crushing component 2 stirs and crushes the blockage. The spiral conveyor blade 101 conveys the crushed blockage forward, and high-pressure water is sprayed out through the unblocking nozzle 3 to further wash away the crushed blockage, thereby achieving the purpose of rapid unblocking.
