Description
Technical Field
[0001] This utility model relates to the field of dredging equipment technology, specifically, to a pipeline dredging device. Background Technology
[0002] Water supply and drainage pipelines are widely used in various industries, including industrial and mining enterprises and public institutions, and are distributed throughout urban and rural areas. As pipelines that collect and discharge sewage, wastewater, and rainwater over a long period of time, regular dredging of water supply and drainage pipelines and cleaning of silt and dirt inside the pipelines has become an important task that cannot be ignored.
[0003] Current methods for cleaning water supply and drainage pipes typically involve manually pulling and pushing to remove silt and debris from the pipes. If the pipes are too long or severely blocked, it may even require breaking open the ground for repairs. This traditional approach is inefficient, consumes significant manpower and resources, and is ineffective at removing sticky deposits from the pipe walls. As the water supply and drainage pipes age, cleaning will only become more frequent and difficult.
[0004] Therefore, there is an urgent need to develop a high-efficiency, automated, water-saving and environmentally friendly pipeline dredging device. Utility Model Content

[0008] A rotary dredging mechanism includes a dredging component and a rotary drive component. The rotary drive component is installed in the protective accommodating cavity and penetrates the front end plate. The dredging component is connected to the rotary drive component and is installed in front of the front end plate.
[0009] The forward propulsion mechanism includes multiple sets of roller assemblies, which are evenly distributed around the outer side of the cylindrical side plate in the circumferential direction; one set of roller assemblies is connected to a forward drive member to serve as a forward drive wheel set, and the remaining roller assemblies serve as support wheel sets.
[0010] The spray cleaning mechanism includes a cylindrical water tank installed inside the protective accommodating cavity and closely attached to the inner wall of the cylindrical side plate. Spray holes are evenly distributed circumferentially on the outer wall of the cylindrical water tank, and the spray holes extend to the outside through the openings on the cylindrical side plate.
[0011] A portable power source is installed inside the protective cavity and is electrically connected to the rotating sludge removal mechanism, the forward propulsion mechanism, and the spray cleaning mechanism to provide driving force.
[0012] Furthermore, the rotation drive assembly includes:
[0013] The drive shaft, the output end of which is fixedly connected to the center of the dredging component;
[0014] A rotary motor is connected to the input end of the drive shaft to drive the drive shaft to rotate.
[0015] Furthermore, the dredging component includes:
[0016] A barrier-breaking propeller is connected to the output end of the drive shaft;
[0017] The wall scraper is installed at the output end of the drive shaft, located behind the obstacle-breaking propeller.
[0018] Furthermore, the obstacle-clearing propeller includes:
[0019] The propeller shaft is fixedly connected to the output end of the drive shaft;
[0020] Multiple obstacle-breaking blades are arranged in a spiral shape around the propeller shaft.
[0021] Furthermore, the wall scraper includes:
[0022] A flange is inserted through the output end of the drive shaft;
[0023] The cutter head is coaxially and fixedly connected to the flange.
[0024] Multiple scraping blades are evenly distributed along the circumference of the outer wall of the cutter disc on the skirt of the cutter disc.
[0025] Furthermore, the roller assembly includes:
[0026] The mounting bracket is fixed to the middle of the outer side of the cylindrical side plate and is parallel to the axis of the cylindrical side plate;
[0027] Two wheel frames are symmetrically hinged to the front and rear ends of the mounting frame via hinged ends, and each forms an angle with the mounting frame;
[0028] Two rollers are symmetrically mounted on the support ends of two wheel frames via wheel axles, the wheel axles being perpendicular to the axis of the cylindrical side plate;
[0029] A tension spring is parallel to the axis of the cylindrical side plate, and its two ends are respectively connected to the middle of the two wheel frames.
[0030] Furthermore, the rear end cover of the cylindrical water tank is closely attached to the rear end plate, and a quick water pipe interface is installed on it, which extends to the outside through the opening on the rear end plate to connect with the booster pump water pipe.
[0031] Furthermore, two bolts are respectively installed in the middle of the two wheel frames, the bolts are perpendicular to the axis of the cylindrical side plate, and the two ends of the tension spring are respectively hooked onto the two bolts.
[0032] Furthermore, the edge of the obstacle-breaking blade is curved.
[0033] Furthermore, the flange is radially oriented.
[0034] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0035] This invention provides a pipe dredging device. Its forward propulsion mechanism allows it to be internally supported within a pipe and move independently along it. By adjusting the angle of the forward propulsion mechanism, it can enter water supply and drainage pipes of different diameters. The obstruction-breaking propeller at the foremost end can rotate and break up large, hard blockages encountered during the device's movement, ensuring unobstructed flow. The rear-mounted scraper, equipped with densely arranged blades, further breaks down the broken blockages into smaller pieces, facilitating subsequent flushing.
[0036] Compared to existing dredging methods, this pipeline dredging device, through the cooperation of dredging components and forward propulsion mechanism, can automatically break up and remove hard blockages that are difficult to clean inside the pipeline. It has the advantages of automated dredging, thorough dredging, and high efficiency. It can also adapt to pipelines of different diameters and materials, flexibly responding to various dredging needs, and has strong adaptability. At the same time, the high degree of automation and simple operation of this pipeline dredging device further improves dredging efficiency, reduces labor costs, and the design takes safety factors into account, reducing the risk of personnel entering the pipeline and ensuring operational safety.
[0037] This invention eliminates the need for a built-in booster pump. Instead, the pump's water pipe can be connected to the water tank via a quick-connect water pipe interface, allowing water to be pumped directly into the tank and sprayed onto the inner wall of the pipe. Compared to traditional water pipe flushing methods, this not only improves flushing efficiency but also saves a considerable amount of water, achieving water conservation and environmental protection.

[0055] In some embodiments, the cylindrical side plate 11 is composed of several rectangular side plates, and its cross-sectional shape, as well as the shapes of the front end plate 12 and the rear end plate 13, are regular hexagons. Other regular polygons, such as equilateral triangles, regular pentagons, or circles, may also be used. The protective connection mechanism 1 effectively protects the components installed in the protective accommodating cavity A, preventing debris removed by the rotating sludge removal mechanism 2 from entering the device and causing damage to the internal power supply and rotating motor 232.
[0056] Figure 4 This is a schematic diagram of the rotating sludge removal mechanism 2 of this utility model. The following is in conjunction with... Figure 4 and Figure 2 The specific structure of the rotating sludge removal mechanism 2 in this utility model is described in detail.

[0058] Preferably, the rotary drive assembly includes a drive shaft 231 and a rotary motor 232. The output end of the drive shaft 231 is fixedly connected to the center of the dredging assembly. The rotary motor 232 is connected to the input end of the drive shaft 231 to drive the drive shaft 231 to rotate.
[0059] Preferably, the dredging assembly includes a barrier-breaking propeller 21 and a wall scraper 22; the barrier-breaking propeller 21 is connected to the output end of the drive shaft 231; the wall scraper 22 is installed at the output end of the drive shaft 231 and located behind the barrier-breaking propeller 21. The barrier-breaking propeller 21 is located at the forefront of the pipeline dredging device and is used to handle large, hard blockages encountered during the advancement of the pipeline dredging device, performing rotational crushing to maintain unobstructed progress. The wall scraper 22 is installed behind the barrier-breaking propeller 21 to further crush the blockages after they have been broken up by the barrier-breaking propeller 21, making them smaller objects. At the same time, the wall scraper 22 can remove sticky deposits from the pipe wall during its rotational advancement. The drive shaft 231 is connected to a rotary motor 232, allowing the barrier-breaking propeller 21 and the wall scraper 22 to rotate simultaneously. Their combined operation makes this pipeline dredging device suitable for most pipeline blockage situations.
[0060] Preferably, the obstacle-breaking propeller 21 includes a propeller shaft 211 and a plurality of obstacle-breaking blades 212; the propeller shaft 211 is fixedly connected to the output end of the drive shaft 231; the plurality of obstacle-breaking blades 212 are arranged in a spiral shape around the propeller shaft 211. In some embodiments, the edges of the obstacle-breaking blades 212 are curved to improve their efficiency in breaking up blockages, and they are made of high-hardness alloy materials, such as stainless steel, alloy steel or other wear-resistant materials, to improve their durability and cutting ability.

At the same time, the closely arranged wall scraping blades 223 can make full contact with the pipe wall, effectively scraping away the blockage that is difficult to remove from the pipe wall. Moreover, the connection between the wall scraping blades 223 and the skirt of the cutter head 222 is detachable, which is easy to replace and allows for quick replacement after wear.
[0062] In some embodiments, flange 221 is radially arranged.
[0063] Figure 5 This is a schematic diagram of the forward motion mechanism 3 of this utility model. The following is in conjunction with... Figure 5 The specific structure of the forward motion mechanism 3 in this utility model is described in detail.
[0064] like Figure 5 As shown, the forward propulsion mechanism 3 includes multiple sets of roller 313 assemblies 31, which are evenly distributed around the cylindrical side plate 11 on the outer side of the cylindrical side plate 11. One set of roller 313 assemblies 31 is connected to a forward drive component to serve as a forward drive wheel set, while the remaining roller 313 assemblies 31 serve as support wheel sets. The forward drive wheel sets drive the support wheel sets forward. The single-power structure can avoid the jamming caused by the asynchrony of multiple power structures, making the pipeline dredging device move forward more smoothly.
[0065] Preferably, the roller 313 assembly 31 includes a mounting frame 311, two wheel frames 312, two rollers 313, and a tension spring. The mounting frame 311 is fixed to the outer middle of the cylindrical side plate 11 and is parallel to the axis of the cylindrical side plate 11. The two wheel frames 312 are symmetrically hinged to the front and rear ends of the mounting frame 311 through hinge ends, and each forms an angle with the mounting frame 311. The two rollers 313 are symmetrically mounted on the support ends of the two wheel frames 312 through wheel axles, and the wheel axles are perpendicular to the axis of the cylindrical side plate 11. The tension spring is parallel to the axis of the cylindrical side plate 11, and the two ends of the tension spring are respectively connected to the middle of the two wheel frames 312. In some embodiments, two bolts 314 are respectively installed in the middle of the two wheel frames 312, the bolts 314 are perpendicular to the axis of the cylindrical side plate 11, and the two ends of the tension spring are respectively hooked onto the two bolts 314. The hinged wheel frame 312, in conjunction with the tension spring, allows the opening angle of the wheel frame 312 to be adjusted, thereby ensuring uniform contact between the roller 313 assembly 31 and the inner wall of the pipe. This allows the roller to adapt to different pipe diameters and maintain stable operation without manual intervention, while also evenly distributing the load and reducing damage to the inner wall of the pipe.
[0066] Figure 6 This is a schematic diagram of the spray cleaning mechanism 4 of this utility model. The following is in conjunction with... Figure 6 The specific structure of the spray cleaning mechanism 4 in this utility model is described in detail.
[0067] like Figure 6 As shown, the spray cleaning mechanism 4 includes a cylindrical water tank 41, which is installed inside the protective accommodating cavity A and closely attached to the inner wall of the cylindrical side plate 11.

The cylindrical water tank 41, installed inside the protective accommodating cavity A and closely attached to the inner wall of the cylindrical side plate 11, saves space while ensuring a compact structure. The evenly distributed circumferential spray holes 42 on the outer wall of the cylindrical water tank 41 ensure a wide and uniform coverage area when spraying cleaning liquid, improving cleaning efficiency. The cylindrical water tank 41 can be easily connected to a water pipe with a small booster pump via a quick water pipe interface 43, so that water can be transported to the cylindrical water tank 41 through the water pipe. During operation, the water in the cylindrical water tank 41 is sprayed onto the inner wall of the pipe through the spray hole 42 for rinsing, which can further clean the residual dirt in the pipe. Compared with the original water pipe flushing method, it can not only improve the cleaning efficiency, but also save a considerable amount of water resources.
