Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pipe dredging technology, and in particular to a water pipeline dredging device. Background Technology
[0002] Water pipelines are essential facilities for transporting water resources. They generally consist of the main pipe body, connecting fittings, valves, and other components. The main pipe body is made of various materials, such as metal and plastic, and can withstand certain pressures to ensure stable water flow. Connecting fittings ensure tight connections between pipe sections, while valves control the start and stop of water flow and regulate flow rate, collectively ensuring the effective completion of the water transport task. The use of dredging devices in water pipelines is extremely crucial. Sediment and impurities in the water accumulate to form silt, reducing water transport capacity, easily causing blockages, and affecting water supply operations. Furthermore, silt accelerates pipe corrosion and wear, shortening its lifespan, and its harmful substances can pollute the water quality. Regular dredging is of great significance for restoring water transport, preventing blockages, protecting pipes, maintaining water quality, and maintaining the stability of the water supply system.
[0003] Existing water pipeline dredging equipment exhibits diverse structures. Walking and driving mechanisms include wheeled structures, powered by motors driving rubber wheels for flexible and rapid movement; tracked structures with large contact area tracks, suitable for large-diameter, uneven pipelines; and spiral propulsion structures that generate thrust through spiral blades, ensuring stable operation over long distances. Dredging and excavation techniques encompass high-pressure water jets and chain bucket excavators. Collection and conveying methods include suction pumps, pneumatic conveying, and spiral conveying structures. Additionally, there are detection and monitoring, power and control, and auxiliary support and protection structures, each performing its specific function to ensure efficient and precise dredging operations.
[0004] However, existing water pipeline dredging devices typically use a chain bucket method, which has many drawbacks. The chain bucket structure is relatively complex, and numerous components operating in the harsh underwater environment for extended periods are prone to wear, deformation, and corrosion. Frequent repairs and replacements not only increase equipment maintenance costs but also disrupt dredging operations, affecting the normal maintenance schedule of the water pipeline. Furthermore, when excavating hard or sticky silt and clumps, the chain bucket is less effective, easily leading to bucket blockage and residual silt, resulting in incomplete dredging. This, in turn, affects the water delivery efficiency and water quality safety of the pipeline. Over time, silt accumulation can also exacerbate localized corrosion, shortening the pipeline's lifespan. Therefore, this paper proposes a new water pipeline dredging device to address these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a water pipeline dredging device, which aims to improve the problem that the existing technology of using chain buckets for dredging has poor digging effect on some hard or sticky silt and clumps.

[0016] The wrench is rotatably connected to a connecting post, and a fixed post is slidably connected to the connecting post. One end of the fixed post is fixedly connected to the side wall of the clamping plate.
[0017] As a further description of the above technical solution:

This solves the problem that the traditional fixed type is too troublesome to maintain the internal suction machine, resulting in reduced dredging efficiency, and improves the convenience of the water pipeline dredging device.

[0030] 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 protection scope of the present utility model.
[0031] Reference Figures 1-3 An embodiment of this utility model provides a water pipeline dredging device, including a pipeline moving mechanism 1. The pipeline moving mechanism 1 is usually made of high-strength aluminum alloy, which has good strength and rigidity, can withstand various external impacts when moving in the water pipeline, and has a light weight, making it easy to move flexibly in the pipeline. A first fixing ring 3 is fixedly connected inside the pipeline moving mechanism 1. A hollow block 11 is fixedly connected inside the pipeline moving mechanism 1. A suction machine 8 is fixedly connected inside the hollow block 11. A sewage pipe 9 is fixedly connected to the output end of the suction machine 8. The sewage pipe 9 is mostly made of wear-resistant rubber material, whose flexibility can adapt to the complex spatial layout inside the pipeline, making it easy to transport the suctioned sludge and other impurities to the designated discharge position. A suction pipe 10 is fixedly connected to the input end of the suction machine 8. A drive component is set inside the pipeline moving mechanism 1.
[0032] The drive assembly includes a motor 7, with a rotating disk 2 fixedly connected to the output end of the motor 7. The rotating disk 2 can be made of alloy steel, possessing high strength and wear resistance. A cutting blade 5 is fixedly connected inside the rotating disk 2. The cutting blade 5 is typically made of carbide and has a sharp blade edge, effectively cutting branches, plastics, and other debris inside the pipe, breaking them into smaller fragments to facilitate subsequent suction and cleaning operations, preventing large debris from clogging the pipe or affecting the operation of the dredging device. A crushing column 4 is rotatably connected inside the rotating disk 2. The crushing column 4 can be made of quenched steel. Made of fire-resistant steel, it has high hardness and can crush harder materials in the pipe. Rotating blades 6 are fixedly connected inside the rotating disk 2. A connecting component is provided on the outer wall of the hollow block 11. A second fixing ring 19 is fixedly connected to the outer wall of the suction pipe 10. The second fixing ring 19 can be made of metal so that the suction pipe 10 can be accurately positioned to perform sludge suction operation. The bottom of the second fixing ring 19 is fixedly connected to the inside of the pipe moving mechanism 1. A first fixing ring 3 is fixedly connected to the outer wall of the sewage pipe 9. The side wall of the first fixing ring 3 is fixedly connected to the inside of the pipe moving mechanism 1.
[0033] Specifically, during water pipeline dredging operations, the pipeline moving mechanism 1 is precisely positioned at the starting point inside the cleaned pipeline. Next, the iris mechanism on the side wall of the pipeline moving mechanism 1 is closed to ensure the sealing and stability of the device during movement within the pipeline. Then, the device is propelled smoothly within the pipeline by the force of fluid flow. At this time, the motor 7 is activated, and its powerful output drives the rotating disk 2 to rotate rapidly. The rotating disk 2, like a tireless dancer, drives the internal cutting blades 5 to rotate at high speed. During the rotation of the rotating disk 2, the cutting blades 5 precisely adhere to and shred debris such as branches and plastic, creating a smoother path for subsequent dredging work and allowing the device to move more steadily and continuously within the pipeline. Simultaneously, the rapid rotation of the rotating disk 2 also drives the internal sturdy and powerful breaking column 4 to rotate violently. It is worth mentioning that the outer wall of the crushing column 4 is cleverly equipped with multiple round and hard spheres. During high-speed rotation, these spheres can crush the hard materials inside the pipe. Finally, the sludge is sucked in through the suction pipe 10 via the input end of the suction machine 8. Then, the suction machine 8, with its efficient output end, steadily and smoothly discharges the sludge through the drain pipe 9, effectively ensuring the cleanliness and unobstructed flow of the water pipeline.
[0034] Reference Figure 1 , Figure 3 and Figure 4 The connecting components include a connecting block 12, which is typically made of robust engineering plastic material, which has good mechanical strength and corrosion resistance. The side wall of the connecting block 12 is fixedly connected to the side wall of the hollow block 11. The bottom of the hollow block 11 is located inside the pipe moving mechanism 1. A retaining ring 13 is fixedly connected inside the connecting block 12. A retaining plate 14 is provided on the inner wall of the retaining ring 13. The retaining plate 14 can be made of hard alloy, which can withstand greater friction and impact. A hollow groove plate 16 is fixedly connected inside the pipe moving mechanism 1. A wrench 17 is rotatably connected to the inner wall of the hollow groove plate 16. The wrench 17 is generally made of metal, such as carbon steel, with a rust-proof surface, making it easy to operate and durable. A connecting post 18 is rotatably connected inside the wrench 17. A fixing post 15 is slidably connected inside the connecting post 18. The fixing post 15 is typically made of stainless steel. One end of the fixing post 15 is fixedly connected to the side wall of the retaining plate 14.
[0035] Specifically, when maintenance is required on the suction machine 8, the maintenance personnel must first hold a special wrench 17 and then steadily turn it. The moment the wrench 17 is applied, it will forcefully move the connecting column 18 on its inner wall smoothly. Once the connecting column 18 moves, it will naturally cause the connected internal fixed column 15 to slide smoothly along a predetermined track. During this process, the connecting column 18 will slide precisely within the internal space of the fixed column 15. Then, as the fixed column 15 continues to slide, it will cleverly move the clamping plate 14, allowing it to rotate flexibly around a specific axis. As the clamping plate 14 rotates, its inner wall will gradually disengage from the inner wall of the tightly engaged retaining ring 13. Once this series of actions is successfully completed, maintenance personnel can easily lift the hollow block 11, which makes it extremely convenient to carry out maintenance and replacement work on the internal suction machine 8, thereby ensuring that the entire water pipeline dredging device can be restored to normal operation as soon as possible and ensuring the efficient and continuous dredging operation.
[0036] Working Principle: When using the water pipeline dredging device, first place the pipeline moving mechanism 1 inside the pipeline to be cleaned. Then, close the iris mechanism on the side wall of the pipeline moving mechanism 1, and push it to move it inside the pipeline. The output end of the motor 7 drives the rotating disk 2 to rotate. As the rotating disk 2 rotates, the internal cutting blade 5 is also driven to rotate along with it. During the rotation of the rotating disk 2, the blades on the side of the rotating disk 2 adhere to some branches, plastic and other debris, cutting them up to facilitate movement. Then, during the rotation of the rotating disk 2, the internal crushing column 4 is also driven to rotate. The outer wall of the crushing column 4 has multiple spheres, which can break up the debris inside the pipeline. Harder materials are crushed, achieving efficient and stable sludge removal. The sludge can then be sucked away through the input end of the suction machine 8 and discharged through the drain pipe 9 through the output end of the suction machine 8. When repairing the suction machine 8, first turn the wrench 17. The wrench 17, under force, moves the connecting column 18 on the inner wall. The movement of the connecting column 18 causes the internal fixed column 15 to slide, simultaneously making the connecting column 18 slide inside the fixed column 15. Then, as the fixed column 15 slides, it causes the clamping plate 14 to rotate. When the clamping plate 14 rotates, it disengages the inner wall from the inner wall of the retaining ring 13. Subsequently, the hollow block 11 can be pulled up, facilitating the repair and replacement of the internal suction machine 8.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
