Description

Technical Field

[0001] This utility model relates to the field of iron pipe inner wall cleaning technology, specifically to a large ductile iron pipe inner wall cleaning device. Background Technology

[0002] Ductile iron pipes are pipes made by centrifugally casting molten iron of grade 18 or higher with the addition of spheroidizing agents using a centrifugal ductile iron casting machine at high speed. They are also known as ductile iron pipes or ductile cast pipes, and are mainly used for the transportation of tap water, making them an ideal material for tap water pipelines.

[0003] Large ductile iron pipes require internal cleaning after prolonged use. Chinese patent CN218610850U describes a large pipe internal wall cleaning device for pipeline engineering. This patent uses a water pump to pressurize water and deliver it to a nozzle, which sprays high-pressure water to flush the pipe's internal wall. This method is very common in existing technology. Although this method can clean the pipe's internal wall quickly, the high-pressure water will collect inside the pipe under gravity. Some water will carry dirt along the pipe's internal wall and be discharged, but some water containing dirt will not be discharged directly and will remain inside the pipe. In this case, a second cleaning is usually required, which is quite cumbersome. Therefore, a large ductile iron pipe internal wall cleaning device is proposed to solve the above-mentioned problems. Utility Model Content

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0030] Please see Figure 1 A large ductile iron pipe inner wall cleaning device includes: a cleaning component and a water pump 6 connected to the cleaning component;

[0031] The cleaning component includes a first support 1 and a second support 2, which are interconnected by a rotating nozzle 3. Both the first support 1 and the second support 2 are fitted with a partition ring 5. The rotating nozzle 3 is disposed between the two partition rings 5. The first support 1 is connected to the inlet of the water pump 6 through a water suction pipe 14 disposed between the two partition rings 5. The rotating nozzle 3 is interconnected with the water inlet pipe through the second support 2.

[0032] Based on the above, the setting of the partition ring 5 allows the water flow sprayed from the rotating nozzle 3 to stay between the two partition rings 5, preventing the water with stains from spreading everywhere. The water and stains are then discharged in a directed manner by the water pump 6, which not only prevents the stains from adhering to the inner wall of the cast iron pipe 7 again, but also prevents the sewage from spreading to the external environment and causing pollution.

[0033] like Figure 1 , Figure 2 as well as Figure 3 As shown, the first support member 1 includes a hollow connecting rod 11, a partition ring 5 is sleeved on the outside of the hollow connecting rod 11, a water suction pipe 14 is provided on the outer surface of the hollow connecting rod 11 and communicates with the hollow connecting rod 11, one end of the hollow connecting rod 11 away from the second support member 2 is communicated with the water pump 6, at least three sets of first side plates 12 are provided on the outer surface of the hollow connecting rod 11, a first roller 13 is provided between two first side plates 12 in one set, and the first roller 13 is in contact with the inner wall of the cast iron pipe 7;

[0034] The second support member 2 includes a connecting rod 21. The outer surface of the connecting rod 21 is provided with at least three sets of second side plates 22. A second roller 23 is provided between two second side plates 22 in one set. The second roller 23 is in contact with the inner wall of the cast iron pipe 7. A partition ring 5 is sleeved on the outer surface of the connecting rod 21. The partition ring 5 includes a ring plate 51. The ring plate 51 is a hard plate. A sealing ring 52 is provided on the outer ring of the ring plate 51. The sealing ring 52 is a rubber plate. The sealing ring 52 is in contact with the inner wall of the cast iron pipe 7. The water pump 6 is connected to the hollow connecting rod 11 through a hose and is connected to the suction pipe 14 through the hollow connecting rod 11.

[0035] Based on the above, the arrangement of the first support member 1 and the second support member 2 enables the rotating nozzle 3 to be supported, and under the action of the first roller 13 and the second roller 23, the device can move along the axial direction of the cast iron pipe 7. The arrangement of the partition ring 5 enables the water droplets splashed out by the rotating nozzle 3 to be blocked by the partition ring 5 when the high-pressure water flow sprayed out to flush and clean the inner wall of the cast iron pipe 7, thus preventing the water flow from flowing directly to the outside of the two partition rings 5. The arrangement of the suction pipe 14 enables the sewage that stays between the two partition rings 5 ​​to be sucked into the suction pipe 14 under the action of the water pump 6 and discharged from the drain of the water pump 6.

[0036] The connecting rod 21 allows the side of the second support member 2 away from the rotating nozzle 3 to be connected to the water inlet pipe and the water pump to input water into the interior of the rotating nozzle 3 and spray it out from the nozzle body 32, thereby achieving the effect of flushing and cleaning the inner wall of the cast iron pipe 7.

[0037] like Figures 2-4 As shown, the rotating nozzle 3 includes a rotating component 31. A rotating shaft 33 is provided at one end of the rotating component 31 near the hollow connecting rod 11. The rotating shaft 33 is connected to the hollow connecting rod 11 through a bearing. A rotating tube 34 is provided on the side of the rotating component 31 near the connecting rod 21. The rotating tube 34 extends into the interior of the connecting rod 21 and is connected to the connecting rod 21 through a bearing, and communicates with the connecting rod 21. An annular groove 35 is formed on the outer surface of the rotating tube 34. A sealing ring 4 is provided inside the annular groove 35 to seal and connect with the connecting rod 21.

[0038] The rotating component 31 is a hollow cavity. At least two nozzle bodies 32 are equidistantly arranged on the circumferential surface of the rotating component 31. The nozzle bodies 32 are tangent to the rotating component 31 and are interconnected with the rotating component 31. The nozzles of the two nozzle bodies 32 have opposite directions. The rotating component 31 is interconnected with the connecting rod 21 through the rotating tube 34.

[0039] Based on the above, the arrangement of at least two nozzle bodies 32 ensures that when the high-pressure water jet impacts the inner wall of the cast iron pipe 7, the rotating nozzle 3 rotates under the action of the reverse force, thereby achieving the effect of flushing and cleaning the inner wall of the cast iron pipe 7. The arrangement of the rotating pipe 34 ensures that the second support member 2 and the rotating pipe 34 are not only rotatably connected but also interconnected, ensuring that the water jet can enter the interior of the rotating nozzle 3.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
