Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, specifically a portable pipeline cleaning ball pushing device. Background Technology

[0002] In industrial production, municipal engineering, and building water supply and drainage systems, pipeline cleaning and maintenance are crucial for ensuring the normal operation of these systems. Currently, pipeline cleaning technologies mainly include high-pressure water jet cleaning, mechanical scraping cleaning, chemical cleaning, and ball cleaning. Among these, ball cleaning is widely used for cleaning small and medium-diameter pipelines due to its ease of operation, low cost, and minimal damage to the pipeline.

[0003] Chinese Patent Publication No. CN220837072U discloses a pipe cleaning ball, belonging to the technical field of pipe cleaning equipment. It includes a front ball, a rear ball, and an energy storage impact mechanism. The front ball is made of solid wood and is shaped like a gyroscope, with a conical front end and a cylindrical rear end. The rear ball is made of polyurethane or silicone, is disc-shaped, with cylindrical side walls and a chamfered front end. The diameter of the front ball is larger than that of the rear ball, and the diameter of the rear ball is slightly larger than the inner diameter of the pipe. An energy storage impact mechanism is provided between the front and rear balls. When a water pressure pulse impacts the rear ball, the energy storage impact mechanism stores the impact force and strikes the front ball, causing it to vibrate and move forward. This cleaning ball solves the problem of existing cleaning balls getting stuck in pipes, requiring repeated pressure application at both ends of the pipe to remove them, thus improving the success rate of pipe unblocking and enhancing the cleaning effect. It also eliminates the need for repeated pressure application to both ends of the pipe when the cleaning ball gets stuck.

[0004] In the existing technology, the cleaning of a pipe cleaning ball relies solely on the vibration of the front ball and the contact between the rear ball and the inner wall of the pipe. For stubborn dirt that is tightly attached to the inner wall of the pipe, the impact force generated by vibration alone is insufficient to completely remove it, leaving cleaning residue and failing to achieve deep cleaning of complex dirt. Therefore, we have made improvements and proposed a portable pipe cleaning ball pushing device. Utility Model Content

The two ends of the fixing tube 3 are respectively inserted into the interior of the two cleaning hemispheres 1 and rotatably connected thereto. An adjusting rod 5 is provided inside the cross base 2, and the adjusting rod 5 passes through the cross base 2 and is rotatably connected thereto. First gears 6 are fixedly installed on the corresponding sides of the adjusting rod 5. The two first gears 6 are respectively inserted into the interior of the two cleaning hemispheres 1 and slidably connected thereto.

[0035] In this embodiment of the utility model, the first servo motor 9 is started, and its output end drives the second gear 8 connected to it to rotate. Through gear meshing transmission, the other second gear 8 drives the adjusting rod 5 to rotate synchronously. When the adjusting rod 5 rotates, the first gears 6 on both sides rotate accordingly. Since the first gear 6 meshes with the external gear ring 7 inside the cleaning hemisphere 1, it drives the two cleaning hemispheres 1 to rotate relative to each other around the fixed tube 3 as the axis, so that the cleaning angle can be flexibly adjusted.

[0036] Example 2: Please refer to the appendix of the instruction manual. Figure 1-6 In a preferred embodiment of this utility model, T-shaped rotating blocks 4 are fixedly installed on the side of the two external gear rings 7 that are close to each other.

[0037] Two annular plates 10 are provided on the outer side of the adjusting rod 5. The adjusting rod 5 passes through the two annular plates 10 and is fixedly connected to them. The two annular plates 10 are respectively inserted into the interior of the two T-shaped rotating blocks 4 and are slidably connected to them. Sealing rings are fixedly installed at the junctions of the cleaning hemisphere 1 and the T-shaped rotating blocks 4 with the annular plates 10. Sealing rings are fixedly installed at the junctions of the adjusting rod 5 and the two annular plates 10.

[0038] One-way valves 12 are fixedly installed at both ends of the fixed pipe 3, and the one-way valves 12 are slidably connected to the cleaning hemisphere 1. Water supply pipes 11 are fixedly installed inside the two cross bases 2, and the two ends of the one-way valves 12 are respectively connected to the fixed pipe 3 and the water supply pipes 11. The output end of the one-way valves 12 is inserted into the interior of the water supply pipes 11 and slidably connected to them. Several conical flushing heads 13 are fixedly installed on the side of the two water supply pipes 11 that are far apart from each other. Output holes that cooperate with the conical flushing heads 13 are opened on the two water supply pipes 11. Several conical flushing heads 13 pass through one side of the cleaning hemisphere 1 and are fixedly connected to it.

[0039] Two cleaning hemispheres 1 are fixedly installed with protruding rings 22 on the side of each other. A rubber cleaning sleeve 14 is provided on the outside of the cleaning hemispheres 1 and the rubber cleaning sleeve 14 is fitted on the outside of the cleaning hemispheres 1 and the protruding rings 22. Several conical rinsing heads 13 pass through the rubber cleaning sleeve 14 and are movably connected to it.

[0040] On the side of the cross base 2 away from the cleaning hemisphere 1, a hand grip plate 15, an auxiliary block 16, and a rubber tube 17 are arranged sequentially from far to near. The two ends of the rubber tube 17 are fixedly connected to the cross base 2 and the auxiliary block 16, respectively, and the rubber tube 17 is connected to the cross base 2 and the auxiliary block 16.

[0041] Connecting plates 18 are provided on both sides of the rubber tube 17. Both connecting plates 18 are fixedly connected to the cross base 2 and slidably connected to the auxiliary block 16. Rotating shafts are fixedly installed on both sides of the auxiliary block 16, and the two rotating shafts are respectively inserted into the interior of the two connecting plates 18 and slidably connected to them. Worm gears 19 and limiting plates 21 are fixedly installed on the opposite sides of the two rotating shafts, and the worm gears 19 and limiting plates 21 are rotatably connected to the connecting plates 18. A worm 20 is meshed on the outer side of the worm gear 19, and the worm 20 is rotatably connected to one of the connecting plates 18. A handle is fixedly installed on one side of the worm 20, and the handle passes through one side of one of the connecting plates 18 and is rotatably connected to it.

[0042] One of the cleaning hemispheres 1 has a control module 23 fixedly installed inside it, and the control module 23 is electrically connected to the first servo motor 9.

[0043] In this embodiment of the utility model, when the cleaning hemisphere 1 rotates, the external gear ring 7 drives the T-shaped rotating block 4 to rotate synchronously around the fixed tube 3. The fixed ring forms an axial limit on the T-shaped rotating block 4 to prevent it from shifting axially along the fixed tube 3 during rotation, effectively limiting the axial displacement of the cleaning hemisphere 1, ensuring structural stability during rotation, avoiding gear meshing failure caused by displacement, and extending the service life of the device.

[0044] When the annular plate 10 rotates with the adjusting rod 5, it forms a sliding fit with the inner wall of the T-shaped rotating block 4. The sealing ring tightly fits the contact surface, preventing sewage and impurities in the pipeline from entering the internal structure of the device and preventing internal gears, motors and other components from being contaminated and damaged. The sliding fit between the annular plate 10 and the T-shaped rotating block 4 not only ensures the smooth rotation of the adjusting rod 5, but also enhances the overall structural integrity.

[0045] External high-pressure water is delivered to the one-way valve 12 through the fixed pipe 3. The one-way valve 12 prevents water backflow. The water flow is distributed to each conical flushing head 13 through the water supply pipe 11 and finally sprayed out in the form of a high-pressure water jet to flush the inner wall of the pipe. The conical flushing head 13 enhances the water flow impact force and improves the cleaning efficiency. The distribution design of the water supply pipe 11 and the flushing head realizes all-round flushing of the inner wall of the pipe without any dead corners.

[0046] In this embodiment of the utility model, when the device moves inside the pipe, the rubber cleaning sleeve 14 comes into direct contact with the inner wall of the pipe and removes the attached dirt through friction; the convex ring 22 enhances the connection stability between the rubber cleaning sleeve 14 and the cleaning hemisphere 1, preventing the cleaning sleeve from falling off; the water jet from the conical flushing head 13 passes through the gap of the rubber cleaning sleeve 14, and works together to complete the dual cleaning of rinsing and wiping.

[0047] The operator controls the direction of the device by holding the handle 15. The rubber tube 17 serves as a water supply channel, delivering external water to the cross base 2 and then distributing it to the fixed pipe 3 and the water supply pipe 11. The auxiliary block 16 serves as a connection and force transmission, enhancing the stability of handheld operation.

[0048] By rotating the handle, the worm gear 20 is driven to rotate, which in turn drives the worm wheel 19 and the connected shaft to rotate, thereby causing the auxiliary block 16 to rotate around the shaft within the connecting plate 18, thus realizing the angle adjustment between the cross base 2 and the hand-held part to adapt to changes in the pipeline direction.

[0049] The control module 23 is electrically connected to the peripheral controller. The control module 23 remotely receives external commands to control the start, stop, speed and direction of the first servo motor 9, thereby regulating the rotation state of the cleaning hemisphere 1.

[0050] Example 3: Please refer to the appendix of the instruction manual. Figure 5-6 In a preferred embodiment of this utility model, the auxiliary block 16 is inserted into the handgrip 15 and rotatably connected to it. A rotating ring is fixedly installed on the outer side of the auxiliary block 16 away from the cross base 2, and the rotating ring is rotatably connected to the handgrip 15. A second servo motor is fixedly installed inside the handgrip 15, and a third gear is fixedly installed at the output end of the second servo motor. Several teeth that mesh with the third gear are fixedly installed on the outer side of the rotating ring. The third gear and several teeth are slidably connected to the handgrip 15. Through-hole plates are fixedly installed on the corresponding sides of the handgrip 15 away from the cross base 2. An auxiliary cylinder is fixedly installed on the side of the fixed tube 3 away from the rubber tube 17. A push head is provided on one side of the auxiliary cylinder, and a T-shaped rod is fixedly installed on the side of the push head near the auxiliary cylinder. The T-shaped rod is composed of a square plate and a rod body. The T-shaped rod is inserted into the interior of the auxiliary cylinder and slidably connected to it. A pressure sensor and a reset spring are respectively provided inside the auxiliary cylinder and on both sides of the T-shaped rod. The reset spring is located on the outside of the T-shaped rod, and its two ends are fixedly connected to the T-shaped rod and the auxiliary cylinder respectively. The pressure sensor is embedded in one side of the inner wall of the auxiliary cylinder. The control module 23 is electrically connected to the second servo motor.

[0051] In this embodiment of the utility model, the second servo motor drives the third gear to rotate, which in turn drives the auxiliary block 16 and the cross base 2 to rotate as a whole through meshing with the teeth of the rotating ring, thereby realizing the circumferential angle adjustment of the device. When the device is pushed forward, the push head is pushed by the pipeline resistance to compress the T-shaped rod and the return spring. The pressure sensor detects the pressure value and feeds it back to the control module 23. The control module 23 adjusts the output of the second servo motor according to the pressure data to optimize the pushing force.

[0052] In this embodiment of the utility model, the circumferential angle adjustment function makes the cleaning range more comprehensive; the pressure sensor is linked with the motor to achieve adaptive propulsion, avoiding damage to pipes or devices due to excessive force, and improving operational safety and intelligence; the through-hole plate is easy to cooperate with existing fixing bolts to extend the hand grip plate 15.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
