Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline cleaning technology, and in particular to a pipeline cleaning device. Background Technology

[0002] Municipal sewage pipes need to be cleaned regularly to prevent blockages from causing poor drainage during rainy seasons. Currently, pipe cleaning is mostly done manually by going down into the underground pipes for preliminary cleaning, which is very difficult and inefficient.

[0003] The technical solution disclosed in Chinese Patent No. CN221133461U involves installing multiple connecting rods and support rods inside the insertion tube. The movement of the moving plate drives the multiple connecting rods and support rods to move synchronously. Under the action of the torsion spring, the support rod flips and fits against the inner wall of the slot. As the moving plate continues to move, the length of the support rod extends continuously until the rotating wheel on the support rod contacts the inner wall of the pipe. The multiple support rods effectively support the insertion tube, allowing the insertion tube to move smoothly inside the pipe. At the same time, rotating the nozzle can evenly spray clean water onto the inner wall of the pipe, improving the cleaning effect of the inner wall of the pipe.

[0004] However, the device still has shortcomings: the device cleans the inner wall of the pipe by spraying water in the forward direction. The debris that falls off can easily form a blockage area with the debris that has not been cleaned during the forward movement, which makes the resistance of the device increase and the cleaning work more and more difficult. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a pipeline cleaning device.

[0006] The technical solution of this utility model is as follows: a pipeline cleaning device includes a chassis, on which several support plates are arranged in a circular array around its axis, and rollers are provided on the support plates. A motor B is provided on one set of support plates to drive the rollers on the support plates to rotate.

[0007] The drive assembly connects the chassis to each support plate. When in operation, the drive assembly drives each support plate to move closer or further away synchronously.

[0008] The feed tube has an output end connected to the discharge tube. The feed end side wall of the feed tube has a through hole that communicates with its interior. An auger is installed inside the feed tube. One end of the auger's main shaft extends out of the feed tube and is connected to a rotary cutter. A motor C that drives the auger to rotate is installed on the end cap of the feed tube.

[0009] A sealing ring is fitted around the outside of the feed tube and rotatably connected to it. A through hole is located inside the sealing ring, and a material collecting assembly communicating with the through hole is provided on the sealing ring.

[0010] And a transmission assembly, which drives the main shaft of the auger and the sealing ring to drive the material collection assembly to rotate while the auger is rotating.

[0011] Preferably, a cylindrical cavity is provided inside the chassis, and several through holes communicating with the interior of the cylindrical cavity are arranged in a circular array around its axis on the chassis.

[0012] Preferably, the drive assembly includes sliders, a bidirectional lead screw, and motor A. Two sliders are symmetrically arranged within the cylindrical cavity and slidably connected to its inner wall. Several connecting rods are rotatably connected to the sliders in a circular array. Each set of connecting rods passes through a through hole on a corresponding side and is rotatably connected to a support plate on that side. The bidirectional lead screw is located within the cylindrical cavity and rotatably connected to the housing. The sliders on both sides are helically connected to the corresponding ends of the bidirectional lead screw. Motor A is connected to the housing, and the output end of motor A is connected to the end of the bidirectional lead screw.

[0013] Preferably, the guide tube passes through the slider and is slidably connected to it.

[0014] Preferably, the rotary cutter comprises multiple sets, and the distance between the outer end face of the rotary cutter and the auger shaft gradually decreases in the direction away from the chassis.

[0015] Preferably, the material collection assembly includes an outer pipe, a material collection hopper, and a hydraulic cylinder. The outer pipe is connected to a sealing ring and communicates with a through hole. An inner pipe is slidably connected to the outer pipe. The end of the inner pipe away from the sealing ring is connected to the material collection hopper, which communicates with it. An L-shaped scraper is provided at the opening edge of the material collection hopper, and the horizontal end of the scraper is close to the machine housing. The hydraulic cylinder is connected to the outer pipe, and the end of the push rod of the hydraulic cylinder is connected to the inner pipe.

[0016] Preferably, the transmission assembly includes a ring and gear A. A disc is mounted at the end of the guide pipe away from the discharge pipe. The ring is fitted around the outside of the disc and rotatably connected to it. A connecting plate is mounted on the ring and connected to the outer pipe. Gear grooves are provided on the inner side of the ring. Gear A is coaxially connected to the main shaft of the auger and is located inside the ring. Gear B is rotatably mounted on the disc, located inside the ring, and meshes with both gear A and the gear grooves.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By setting up a structure that synchronously drives the extension and retraction of each support plate through a drive assembly, and by setting up a hydraulic cylinder to push the extension and retraction of the collection hopper, the device can be placed in pipes of different inner diameters to clean the pipes. By setting up a guide pipe with an auger inside, the collection hopper is connected to the inside of the guide pipe through an outer pipe, an inner pipe, a sealing ring, and a through hole. The collection hopper is also connected to the auger through a transmission assembly. When the auger rotates, the collection hopper rotates automatically through the cooperation of gears A and B, as well as the ring and the internal tooth groove of the ring. The scraper on the rotating collection hopper scrapes off and removes the deposits on the inner wall of the pipe. At the same time, this utility model also sets up a rotary cutter on the main shaft of the auger to unclog the blockage inside the pipe and cut up the blockage. Through the cooperation of the collection hopper, the auger, and the guide pipe, the blockage is sucked out of the pipe. Compared with the flushing and pushing method in the prior art, this device has less resistance and higher cleaning efficiency. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-Figure 4As shown, the present invention proposes a pipeline cleaning device, comprising a housing 1, a drive assembly 2, a guide pipe 6, a sealing ring 11, and a transmission assembly. Several support plates 3 are arranged in a circular array around the housing 1's axis, with rollers 4 mounted on each support plate 3. A motor B5 is mounted on one set of support plates 3 to drive the rollers 4 on that support plate 3 to rotate. A cylindrical cavity is formed inside the housing 1, and several through holes 101 communicating with the interior of the cylindrical cavity are arranged in a circular array around the housing 1's axis. The drive assembly 2 connects the housing 1 to each support plate 3, and includes a slider 201, a bidirectional lead screw 203, and a motor A204. Two sliders 201 are symmetrically arranged within the cylindrical cavity and slidably connected to its inner wall. Several connecting rods 202 are rotatably connected to the sliders 201 in a circular array. Each set of connecting rods 202 passes through the through holes 101 on the corresponding side and is rotatably connected to the support plate 3 on that side. A bidirectional lead screw 203 is located inside the cylindrical cavity and is rotatably connected to the housing 1. Two sliders 201 on each side are helically connected to their corresponding ends of the bidirectional lead screw 203. A motor A204 is connected to the housing 1, and its output end is connected to the end of the bidirectional lead screw 203. The drive assembly 2 drives each support plate 3 to move synchronously closer or further away during operation. A guide pipe 6 passes through the slider 201 and is slidably connected to it. The output end of the guide pipe 6 is connected to the discharge pipe 7. A through hole 601 communicating with the inside of the guide pipe 6 is provided on the side wall of its inlet end. An auger 8 is installed inside the guide pipe 6. One end of the auger 8's main shaft extends out of the guide pipe 6 and is connected to a rotary cutter 10. A motor C9 driving the auger 8 to rotate is installed on the end cap of the guide pipe 6. A sealing ring 11 is sleeved on the outside of the guide pipe 6 and rotatably connected to it. The through hole 601 is located inside the sealing ring 11, and a material collecting assembly communicating with the through hole 601 is provided on the sealing ring 11. The material collection assembly includes an outer tube 12, a collection hopper 14, and a hydraulic cylinder 15. The outer tube 12 is connected to a sealing ring 11 and communicates with a through hole 601. An inner tube 13 is slidably connected to the outer tube 12. The end of the inner tube 13 away from the sealing ring 11 is connected to the collection hopper 14, which communicates with it. An L-shaped scraper 141 is provided at the opening edge of the collection hopper 14, and the horizontal end of the scraper 141 is close to the housing 1. The hydraulic cylinder 15 is connected to the outer tube 12, and the push rod end of the hydraulic cylinder 15 is connected to the inner tube 13. The scraper 141 is located behind the collection hopper 14 in the spiral direction to allow the scraped-off accumulated material to smoothly enter the interior of the collection hopper 14. The transmission assembly includes a ring 16 and a gear A18. A disc 602 is provided at the end of the guide pipe 6 away from the discharge pipe 7. The ring 16 is sleeved on the outside of the disc 602 and rotatably connected to it. A connecting plate 17 is provided on the ring 16, and the connecting plate 17 is connected to the outer tube 12. The inner side of the ring 16 is provided with a toothed groove 161. The gear A18 is coaxially connected to the main shaft of the auger 8. The gear A18 is located inside the ring 16, and the gear B19 is rotatably provided on the disc 602. The gear B19 is located inside the ring 16 and meshes with both the gear A18 and the toothed groove 161.The transmission assembly is connected to the main shaft of the auger 8 and the sealing ring 11 to drive the material collection assembly to rotate while the auger 8 is rotating.

[0026] In this embodiment, during use, the casing 1 is first placed inside the pipe, and then the motor A204 is started. The motor A204 drives the bidirectional lead screw 203 to rotate, causing the sliders 201 on both sides to move away from each other, thereby changing the angle of the connecting rod 202. This increases the distance between the support plates 3 so that all rollers 4 abut against the inner wall of the pipe. Then, the hydraulic cylinder 15 is started, driving the inner tube 13 to slide and extending the scraper 141 on the collecting hopper 14 to contact the inner wall of the pipe. Then, the motor C9 is started, driving the auger 8 to rotate. During the rotation of the auger 8, the gear A18 on the main shaft of the auger 8 drives the gear B19 to rotate, and the gear B19... The rotating ring 16 drives the sealing ring 11 and the collecting hopper 14 to rotate around the main shaft of the auger 8. At this time, the scraper 141 on the opening of the collecting hopper 14 scrapes off the deposits on the inner wall of the pipe as the collecting hopper 14 rotates. The scraped deposits enter the collecting hopper 14. Due to the high-speed rotation of the auger 8, air and the deposits in the collecting hopper 14 are quickly drawn into the guide pipe 6 by the airflow. The deposits are then discharged along the discharge pipe 7 by the auger 8. Then, the motor B5 is started, driving the rollers to rotate and thus moving the entire device forward in the pipe, cleaning the pipe network as it moves. While the auger 8 rotates, the rotary cutter 14 in its forward direction rotates at high speed, thus selectively cutting and refining the blockages in the forward direction of the casing 1, preventing the blockages from obstructing the cleaning of the pipe.

[0027] Example 2

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the pipe cleaning device proposed in this utility model, compared with the first embodiment, includes multiple sets of rotary cutters 10, and the distance between the outer end face of the rotary cutter 10 and the axis of the auger 8 gradually decreases in the direction away from the casing 1.

[0029] In this embodiment, as the chassis 1 moves forward, the rotary cutter 10, whose cutting radius gradually decreases, maintains high-speed rotation. When encountering a large blockage, the small-radius rotary cutter 10 first inserts into the blockage to cut and open a hole. Then, the rotary cutter 10, whose cutting radius gradually increases, passes through the blockage along the insertion hole in sequence, thereby gradually decomposing, chopping, and refining the blockage.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
