Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline dredging technology and relates to a dredging device for underground pipelines. Background Technology
[0002] Sewage pipe networks are a crucial part of urban drainage systems and an essential infrastructure for the normal operation of a city. Their primary purpose is to transport domestic sewage and industrial wastewater to sewage treatment plants. Currently, the technical methods for operation and maintenance are still outdated, and blockages are inevitable during use, requiring dredging. Currently, methods such as vacuum trucks to remove sludge and high-pressure water jets are convenient for areas near inspection wells. However, these methods are unsuitable for blockages far from wells where the vacuum truck's hose cannot reach. Some people use steel bars to loosen the blockage, which can hook out soft materials like plastic bags, but this only provides temporary relief. Since only small openings are cleared, the blockage will recur after a while. Water flushing is insufficient and wasteful due to the large volume of water required. When the pipe walls are stained with oil, water flushing alone is insufficient; chemical dispersants are needed. Excessive use of these chemicals also increases the burden on sewage treatment. Therefore, the current manual operation and dredging of pipelines is costly and inefficient. Utility Model Content

The front rotating brush is connected to the circumference of the front rotating disk, which is fixed to the front of the front rotating shaft. The front rotating shaft is equipped with a rotating motor, which drives the front rotating shaft to rotate. The rotating motor is located inside the counterweight housing. The forward anti-slip roller is installed outside the counterweight housing and is a non-drive wheel. The drive motor is connected to the counterweight housing via a connecting rod. The drive motor is connected to a traveling wheel, which is driven to rotate by the drive motor. The waterproof cable is electrically connected to the drive motor and the rotating motor. The traction line is connected to the counterweight housing. The infusion pipeline is a flexible hose, with one end connected to a nozzle, which is fixed to the counterweight housing.
[0005] Furthermore, a rear turntable is provided, with a rear rotating brush connected to the circumference of the rear turntable. The rear turntable is connected to a rotating motor inside the counterweight housing. The rotating motor has a bidirectional output structure, and the drive shaft connected to the rear turntable is a hollow tube, which is sleeved on the outer layer of the connecting rod.
[0006] The nozzles are multiple, facing the front and rear rotating brushes respectively. The nozzles are connected to the infusion pipeline through a ring pipe, which is located inside the counterweight housing.
[0007] Furthermore, the connecting rod is a metal round tube, and the waterproof cable, traction line, and infusion line are placed inside the metal round tube.
[0008] Preferably, the front and rear rotating brushes are made of ABS or PE wire mixed with stainless steel wire.

Detailed Implementation
[0013] A sewage underground pipe dredging device, such as Figure 1 It includes a front rotating brush 1, a front rotating disk 2, a front rotating shaft 3, a counterweight housing 4, a forward anti-slip roller 5, a drive motor 8, a waterproof cable 9, a traction line 10, and an infusion line 11. The front rotating disk 2 is connected to the front rotating brush 1 on its circumference and is fixed to the front of the front rotating shaft 3. The front rotating shaft 3 is equipped with a rotating motor, which drives the front rotating shaft 3 to rotate. The rotating motor is located inside the counterweight housing 4. The forward anti-slip roller 5 is installed on the outside of the counterweight housing 4. The forward anti-slip roller 5 is a non-drive wheel and uses teeth on its outer edge for anti-slip. The drive motor 8 is connected to the counterweight housing 4 through a connecting rod 14. The drive motor 8 is connected to a traveling wheel 15, which is driven by the drive motor 8 to rotate. The waterproof cable 9 is electrically connected to the drive motor 8 and the rotating motor. The traction line 10 is connected to the counterweight housing 4. The infusion line 11 is a flexible hose, and one end of the infusion line 11 is connected to a nozzle 12, which is fixed on the counterweight housing 4.
[0014] Further, a rear turntable 7 can be provided, with a rear rotating brush 6 connected to its circumference. The rear turntable 7 is connected to a rotating motor inside the counterweight housing 4. The rotating motor has a bidirectional output structure, and the drive shaft 16 connected to the rear turntable 7 is a hollow tube, which is sleeved on the outer layer of the connecting rod 14. The rear rotating brush 6 enhances the removal effect of silt.
[0015] Multiple nozzles 12 are provided, facing the front rotating brush 1 and the rear rotating brush 6 respectively. The nozzles 12 are connected to the infusion line 11 through a ring pipe, which is located inside the counterweight housing 4. The nozzles spray rinsing fluid, simultaneously brushing and spraying for rinsing.
[0016] To ensure a compact structure and prevent pipeline wear and shortened lifespan, the connecting rod 14 is a metal round tube, and the waterproof cable 9, traction line 10, and infusion line 11 are placed inside the metal round tube.
[0017] The front rotating brush 1 and the rear rotating brush 6 are made of ABS or PE wire mixed with stainless steel wire. The combination of metal and non-metal wires in the bristles can remove stubborn dirt and also clean areas that are difficult for steel wire to reach.
[0018] Furthermore, the front end of the front rotating shaft 3 is set with a conical tip 13, which can break through the blockage layer when the mud and sand that are not easy to wash away block the device's progress, allowing the device to move forward.
[0019] The device works as follows: The dredging device enters the dredging pipeline via the traction line 10. The drive motor 8 is turned on, driving the traveling wheels 15 to rotate. The traveling wheels 15 and the forward anti-slip rollers 5 rotate along the pipe wall, propelling the device forward. The infusion line 11 supplies water to the nozzles 12. The front rotating brush 1 and the rear rotating brush 6 are driven by the rotating motor to rotate and sweep, cleaning the silt and sediment in the pipeline. Once the slurry becomes fluid, the blockage in the pipeline is cleared, and the subsequent flow of sewage carries the silt and sediment into the sewage tank. After cleaning, the drive motor 8 is turned off, and the device is pulled out of the pipeline using the traction line 10.
