Description

Technical Field

[0001] This utility model relates to the technical field of pipeline sludge cleaning devices, specifically a pipeline sludge cleaning device suitable for pipelines of different diameters. Background Technology

[0002] A pipe sludge cleaner is a device used to remove silt, debris, and blockages from pipes. Widely used in urban drainage pipes, industrial wastewater pipes, and agricultural irrigation pipes, it effectively removes silt, debris, and blockages, ensuring unobstructed pipe flow.

[0003] For example, in the case of a pipeline dredging device (CN218814287U), the output shaft of a drive motor drives a rotating ring to rotate via a rotating shaft. The rotating ring drives a scraper to rotate, and the scraper scrapes off the dirt on the inner wall of the pipeline. The dirt enters the cavity through a through groove and is then discharged from the drain pipe. The device is simple to operate and convenient to use. The connecting sleeve can be removed by unscrewing the bolts. Different diameter rotating rings can be replaced according to the inner diameter of the pipeline. The brush facilitates the cleaning of residual dirt on the inner wall of the pipeline, greatly improving its practicality.

[0004] When using the pipe cleaning device described above, it is necessary to replace the hanging rods of different lengths according to the pipe diameter to adapt to the pipe diameter. This method of adapting to the pipe diameter is relatively cumbersome to operate, and the adjustable length is relatively fixed, which has great limitations. It is difficult to fit tightly against the inner wall of the pipe, making it inconvenient to clear the blockage. Utility Model Content

[0005] The purpose of this invention is to provide a pipe cleaning device suitable for pipes of different diameters, so as to solve the problem mentioned in the background art that existing pipe cleaning devices are difficult to adapt to pipe diameters.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe cleaning device suitable for pipes of different diameters, comprising: a body and a locking mechanism, wherein a connecting pipe is fixed to one end of the body, and a motor housing is fixed inside the body.

[0007] The output end of the motor housing is fixed with a drive shaft, one end of which is fixed with a connecting block. Inside the connecting block, a connecting seat is movably connected via a rotating shaft. A connecting rod is fixedly connected to one side of the connecting seat, and a rubber sleeve is fixed to the outside of the connecting rod. One side of the rubber sleeve is fixedly connected to the connecting block. One end of the connecting rod is movably connected to a scraper via a damping rotating shaft. Inside the connecting block, a threaded rod a is movably connected via a bearing. A rack rod is threadedly connected to the outside of the threaded rod a. Multiple sets of gears are meshed on the outside of the rack rod. Both sides of the gears are fixedly connected to the connecting seat. The inside of the connecting block has a rotating groove that matches the connecting rod. One end of the threaded rod a is provided with a locking mechanism.

[0008] Preferably, multiple sets of fixing blocks are fixed to the outside of the machine body, and the fixing blocks are internally threaded with threaded rods b.

[0009] Preferably, one end of the threaded rod b is movably connected to a bracket via a rotating shaft, one end of the bracket is movably connected to a roller via a rotating shaft, a limit rod is slidably connected to one side of the bracket, and one end of the limit rod is fixedly connected to the machine body.

[0010] Preferably, the engaging mechanism includes a handle that is slidably connected to one end of the threaded rod a, and a rotating block is movably connected inside the handle via a rotating shaft.

[0011] Preferably, a tension spring is fixedly connected to one side of the rotating block, and one end of the tension spring is fixedly connected to the threaded rod a.

[0012] Preferably, a protrusion is fixedly connected to one end of the threaded rod a near the tension spring, and an annular groove is provided inside the handle, with the annular groove slidably connected to the protrusion.

[0013] Preferably, a limiting groove is provided on one side of the protrusion, and the limiting groove is formed inside the handle.

[0014] Compared with existing technologies, the advantages of this pipe cleaning device suitable for pipes of different diameters are as follows: When cleaning pipes of different diameters, the pipe cleaning device extends the tension spring by pulling the handle in the locking mechanism. When the limiting groove in the handle engages with the protrusion at the end of the threaded rod a, the handle can be rotated to drive the threaded rod a and the rack rod to perform threaded transmission, which in turn drives the rack rod to move. The rack rod will mesh with multiple sets of gears, thereby driving the gears and connecting rod to rotate. The scraper will also move to adapt to the diameter of the pipe. After adjustment, the rotatable scraper can be made to fit against the inner wall of the pipe. At this time, when the motor box is started, the transmission shaft will drive multiple sets of scrapers to scrape the inner wall of the pipe, causing the sludge to fall off. In this way, the pipe cleaning device can be used to clean pipes of different diameters through the above operation. Attached Figure Description

[0022] Please see Figures 1-5 This utility model provides a technical solution: a pipe cleaning device suitable for pipes of different diameters, comprising: a body 1 and a locking mechanism 15, a connecting pipe 2 fixed to one end of the body 1, and a motor housing 3 fixed inside the body 1.

[0023] A drive shaft 4 is fixed to the output end of the motor housing 3. A connecting block 5 is fixed to one end of the drive shaft 4. A connecting seat 13 is movably connected to the inside of the connecting block 5 via a rotating shaft. A connecting rod 6 is fixedly connected to one side of the connecting seat 13. A rubber sleeve 7 is fixed to the outside of the connecting rod 6. One side of the rubber sleeve 7 is fixedly connected to the connecting block 5. A scraper 8 is movably connected to one end of the connecting rod 6 via a damping rotating shaft. A threaded rod a9 is movably connected to the inside of the connecting block 5 via a bearing. A rack rod 10 is threadedly connected to the outside of the threaded rod a9. Multiple sets of gears 11 are meshed to the outside of the rack rod 10. Both sides of the gears 11 are fixedly connected to the connecting seat 13. A rotating groove 12 matching the connecting rod 6 is opened inside the connecting block 5. A locking mechanism 15 is provided at one end of the threaded rod a9.

[0024] Multiple sets of fixing blocks 16 are fixed to the outer side of the body 1. A threaded rod b17 is threadedly connected to the inside of each fixing block 16. One end of the threaded rod b17 is movably connected to a bracket 18 via a rotating shaft. One end of the bracket 18 is movably connected to a roller 14 via a rotating shaft. A limit rod 19 is slidably connected to one side of the bracket 18. One end of the limit rod 19 is fixedly connected to the body 1. The threaded rod a9 and the rack rod 10 form a threaded transmission structure, and the rack rod 10 and the gear 11 form a meshing transmission structure. The engaging mechanism 15 includes a handle 151 slidably connected to one end of the threaded rod a9. A rotating block 152 is movably connected inside the handle 151 via a pivot. A tension spring 153 is fixedly connected to one side of the rotating block 152, and one end of the tension spring 153 is fixedly connected to a threaded rod a9. A protrusion 154 is fixedly connected to one end of the threaded rod a9 near the tension spring 153. An annular groove 155 is provided inside the handle 151, and the annular groove 155 is slidably connected to the protrusion 154. A limiting groove 156 is provided on one side of the protrusion 154, and the limiting groove 156 is provided inside the handle 151. The rotating block 152 and the handle 151 form a rotating structure through the pivot.

[0025] In practical implementation, this pipe cleaning device, applicable to pipes of different diameters, when clearing blockages in pipes of different diameters, extends the tension spring 153 by pulling the handle 151 in the locking mechanism 15. When the limiting groove 156 in the handle 151 engages with the protrusion 154 at the end of the threaded rod a9, the handle 151 can be rotated to drive the threaded rod a9 and the rack rod 10 through threaded transmission, causing the rack rod 10 to move. The rack rod 10 will mesh with multiple sets of gears 11, thereby driving the gears 11 and the connecting rod 6 to rotate. The scraper 8 will also move to adapt to the pipe diameter. After adjustment, the scraper 8 can be rotated to fit against the inner wall of the pipe. After adjustment, the handle 151 can be released, at which point the tension spring 153... The device will reset and pull the handle 151 to move it, causing the limiting groove 156 inside the handle 151 to disengage from the protrusion 154 and enter the annular groove 155. At this time, the handle 151 will rotate freely to prevent the threaded rod a9 from rotating accidentally. When the motor box 3 is started, the transmission shaft 4 will drive multiple sets of scrapers 8 to scrape the inner wall of the pipe, causing the sludge to fall off. At the same time, by rotating the threaded rod b17 and the fixed block 16 for threaded transmission, the bracket 18 can be moved, causing the roller 14 at the bottom of the bracket 18 to contact the inner wall of the pipe, allowing the pipe cleaner to move in pipes of different diameters. In this way, the pipe cleaner can be used to clear blockages in pipes of different diameters through the above operations.

[0026] In summary: When using a pipe cleaning device suitable for pipes of different diameters, first connect the connecting pipe 2 at one end of the machine body 1 to the vacuum pump, then send the machine body 1 into the pipe. The scraper 8 can clean the sludge on the inner wall of the pipe, and then the vacuum pump sends the sludge out of the pipe.
