Description

Technical Field

[0001] This utility model relates to the field of dredging mechanisms, and more particularly to a dredging mechanism for municipal pipelines. Background Technology

[0002] Dredging agencies are organizations or units that specialize in cleaning up silt. Municipal pipelines need dredging agencies because after long-term use, debris accumulates inside the pipelines. This not only reduces drainage capacity, leading to urban flooding that affects traffic and the safety of residents' lives and property, but also damages the pipelines due to corrosive substances in the debris, causing sewage leaks that pollute the soil and groundwater. Furthermore, silt can breed bacteria and germs, producing odors that endanger residents' health. In addition, if sewage overflows into nearby water bodies, it will damage the urban ecological environment. Therefore, regular cleaning by dredging agencies is crucial for maintaining the normal operation of municipal pipelines and the urban environment.

[0003] The existing municipal pipeline dredging mechanisms mainly operate on the following principles: Mechanical dredging utilizes a cutter head to break up silt and debris, which is then sucked out by a sludge pump. This is suitable for cleaning silt containing hard debris. Grab dredging uses a crane or dredging truck's grab bucket to grab and transport the silt, capable of handling lumpy silt and large debris. Hydraulic dredging employs high-pressure water jet dredging, which relies on high-pressure water flow to disperse the silt into a slurry, allowing it to be naturally discharged or pumped out. This method is effective for cleaning soft silt and complex areas. Hydraulic flushing dredging involves introducing a high-speed water flow upstream to flush the silt downstream. Additionally, manual dredging is used when pipe diameter is small, equipment is difficult to access, or in special circumstances. Workers wearing protective gear enter the pipeline and use tools to shovel and transport the silt, but this method is less efficient and carries certain risks.

[0004] While dredging agencies play a vital role in municipal pipeline dredging, several shortcomings remain. One particularly prominent issue is the failure to effectively address the compatibility of equipment with different sludge conditions. Sludge in municipal pipelines is complex and diverse, ranging from sticky sludge formed by long-term sewage sedimentation to thick silt mixed with large amounts of sand and gravel, and even various types of construction waste, household waste, and other debris. Existing dredging equipment often has limited functionality, leading to frequent equipment changes based on sludge conditions during actual dredging operations. This cumbersome process significantly impacts the convenience of municipal pipeline dredging agencies, reduces dredging efficiency, and increases manpower, material, and time costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sludge dredging mechanism for municipal pipelines, aiming to improve the problem that different sludge conditions require different equipment for treatment during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dredging mechanism for municipal pipelines, comprising a housing, a sewage pipe fixedly connected inside the housing, a water inlet pipe fixedly connected inside the housing, multiple guide wheels fixedly connected to the outer wall of the housing, a drive assembly disposed inside the housing, a rotating shaft rotatably connected inside the housing, a liquid guide fan fixedly connected to the outer wall of the rotating shaft, a water spray wheel fixedly connected to the outer wall of the rotating shaft, a water spray head fixedly connected inside the water spray wheel, a fixed column fixedly connected to one end of the rotating shaft, a connecting column slidably connected inside the fixed column, multiple fixing components disposed inside the connecting column, a connecting shaft fixedly connected to one end of the connecting column, and a stirring assembly disposed on the outer wall of the connecting shaft;

[0007] Each of the fixing components includes a locking pin, a limiting plate, and a spring.

The output end of the motor is connected to one end of the drive gear. One end of the drive gear is fixedly connected to one end of the motor. One side of the driven gear is fixedly connected to one end of the rotating shaft. The drive gear and the driven gear mesh with each other.

[0012] As a further description of the above technical solution:

In this utility model, the water flowing into the inlet pipe is not only sprayed into the pipe through the spray wheel, but also flows into the diversion pipe, then into the guide pipe, and then into the booster pipe. After the pressure is changed, the water is sprayed into the inlet of the sewage pipe by the spray head connected to the spray pipe. This achieves the effect of dispersing large pieces of sludge at the inlet of the sewage pipe during the use of the equipment, avoiding the problem of large pieces of sludge clogging the sewage pipe and causing equipment failure. This improves the efficiency of the municipal pipeline dredging mechanism. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a municipal pipeline dredging mechanism, comprising a housing 1, a drain pipe 2 fixedly connected inside the housing 1 for discharging crushed sludge, a water inlet pipe 3 fixedly connected inside the housing 1 for introducing clean water, multiple guide wheels 4 fixedly connected to the outer wall of the housing 1 for guiding the movement of the equipment, a drive assembly inside the housing 1, and a rotating shaft 8 rotatably connected inside the housing 1 for driving the components at the front end of the equipment to rotate, with a liquid guide fixedly connected to the outer wall of the rotating shaft 8. Fan 9 is used to guide the crushed sludge into the sewage pipe 2. A water spray wheel 10 is fixedly connected to the outer wall of the rotating shaft 8 for mounting water spray heads 11. The water spray wheel 10 is fixedly connected to the water spray heads 11 for spraying clean water. A fixed column 12 is fixedly connected to one end of the rotating shaft 8 for connecting to the connecting shaft 17. A connecting column 13 is slidably connected inside the fixed column 12. Multiple fixing components are provided inside the connecting column 13. A connecting shaft 17 is fixedly connected to one end of the connecting column 13. A stirring component is provided on the outer wall of the connecting shaft 17.

[0034] Each fixing component includes a locking pin 14, a limiting plate 15, and a spring 16. The outer wall of the locking pin 14 is slidably connected to the inside of the connecting post 13 to fix the connecting shaft 17. The outer wall of the locking pin 14 passes through the inside of the fixing post 12. The inner wall of the limiting plate 15 is fixedly connected to the outer wall of the locking pin 14 to limit the movement range of the locking pin 14. The spring 16 is disposed inside the connecting post 13 to provide a restoring force to the locking pin 14. One end of the spring 16 is fixedly connected to the inside of the locking pin 14, and the other end of the spring 16 is fixedly connected to the inside of the connecting post 13. The stirring assembly includes multiple agitator blades 18 and sludge breaking heads 19, each... One end of each agitator blade 18 is fixedly connected to the outer wall of the connecting shaft 17 for agitating sludge. One end of the sludge breaking head 19 is fixedly connected to one end of the connecting shaft 17 for breaking the surface of the sludge. The drive assembly includes a motor 5, a drive gear 6, and a driven gear 7. The outer wall of the motor 5 is fixedly connected to the inside of the housing 1 for driving the equipment. The output end of the motor 5 is connected to one end of the drive gear 6. One end of the drive gear 6 is fixedly connected to one end of the motor 5 for driving the driven gear 7. One side of the driven gear 7 is fixedly connected to one end of the rotating shaft 8 for driving the rotating shaft 8 to rotate. The drive gear 6 and the driven gear 7 mesh with each other.

[0035] Specifically, when it is necessary to replace different types of agitator blades 18, the operator first presses down the locking pin 14 forcefully so that the locking pin 14 can smoothly retract into the interior of the connecting column 13. After ensuring that the locking pin 14 has fully retracted, the operator holds the connecting shaft 17 and uses appropriate force to pull the connecting column 13, which is tightly connected to it, out of the interior of the fixing column 12. As the connecting column 13 is pulled out, the old agitator blade 18 is successfully removed. Then, the operator picks up the new agitator blade 18, aligns its connecting column 13 with the inlet of the fixing column 12, and inserts it. When the connecting column 13 is fully inserted into the fixing column 12, the replacement of the agitator blade 18 is successfully completed. The entire process requires the operator to be careful enough to ensure the accuracy and efficiency of the equipment replacement.

[0036] Reference Figure 4 and Figure 5Multiple diversion pipes 20 are fixedly connected to the outer wall of the inlet pipe 3 to divert the introduced clean water. Each diversion pipe 20 has a guide pipe 21 fixedly connected to its bottom to guide the clean water into the booster pipe 22. Each guide pipe 21 has a booster pipe 22 fixedly connected to one side. Each booster pipe 22 has a buffer pipe 23 fixedly connected to one end. Each buffer pipe 23 has a spray pipe 24 fixedly connected to one side to guide the clean water into the spray head 25. Each spray pipe 24 has a spray head 25 fixedly connected to one end for spraying clean water. The drain pipe 2 and the inlet pipe 3 are arranged in a parallel array and fixedly connected inside the housing 1. The spray heads 11 are arranged in a ring array and fixedly connected inside the spray wheel 10. The diversion pipes 20 are arranged in a ring array and fixedly connected to the outer wall of the inlet pipe 3. The guide pipes 21 are arranged in a parallel array and set on one side of the diversion pipe 20.

[0037] Specifically, part of the water flowing in from the inlet pipe 3 rushes towards the spray wheel 10. Driven by the high-speed rotation of the spray wheel 10, it is powerfully sprayed into the pipe in a scattering pattern, forming an initial flushing force on the inside of the pipe. At the same time, another part of the water flows into the diversion pipe 20. This water flows in the diversion pipe 20 and then turns into the guide pipe 21. Guided by the guide pipe 21, the water flows into the booster pipe 22. Inside the booster pipe 22, the water undergoes a process of rapid pressure change, and the pressure is significantly increased. Then, the high-pressure water is transmitted through the spray pipe 24 and finally sprayed out in a columnar high-speed jet from the spray head 25, which is closely connected to the spray pipe 24. It is precisely sprayed at the inlet of the sewage pipe 2. This powerful water flow can effectively and quickly disperse the large and compact sludge accumulated at the inlet of the sewage pipe 2, creating favorable conditions for subsequent sewage discharge work and ensuring that the entire dredging process is carried out more smoothly.

[0038] Working principle: When using the municipal pipeline dredging mechanism, first select the appropriate agitator blade 18 based on the sludge condition. Then, remove the agitator blade 18 from the equipment. First, press down the locking pin 14 to retract it into the connecting column 13. Then, the operator holds the connecting shaft 17 and pulls the connecting column 13 out of the fixed column 12, thus removing the old agitator blade 18. Then, insert the connecting column 13 of the new agitator blade 18 into the fixed column 12 to complete the replacement of the agitator blade 18. Then, connect the outlet of the sewage pipe 2 and the inlet of the water inlet pipe 3 to the corresponding positions, and then start the motor 5. Simultaneously, clean water is introduced into the inlet pipe 3, and the motor 5 drives the drive gear 6 to rotate, which in turn causes the driven gear 7 to rotate, thereby driving the rotating shaft 8 to rotate, causing the spray wheel 10, the agitator blades 18, and the sludge breaking head 19 to rotate, thus treating the sludge. Part of the water flow inside the inlet pipe 3 will flow into the diversion pipe 20, and then from the diversion pipe 20 into the guide pipe 21, and then into the booster pipe 22. After the pressure is changed, the spray head 25 connected to the spray pipe 24 sprays the water onto the inlet of the sewage pipe 2, thereby dispersing the larger pieces of sludge at the inlet of the sewage pipe 2, preventing the sludge from being too large and clogging the sewage pipe 2, thus affecting the operation of the equipment.

[0039] 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.
