[0002] Foam pipe cleaner is a pipe cleaning device made of foaming material. It is a cylindrical body with a conical head, and various wear-resistant scraping materials are cross-wound and coated on its tail or surface. It is mainly used for dewatering and drying inside the pipe. After adding other auxiliary equipment, it can remove impurities such as scale and corrosion products in the pipe, and is used for pipeline detection and tracking. However, the existing foam pipe cleaners are generally large in size, have poor permeability in small-diameter pipes, are easily blocked, and because the foam itself is relatively soft, the outer coating is easily deformed, resulting in reduced cleaning ability.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0038] The utility model respectively arranges a first sealing baffle 20 and a second sealing baffle 30 at the two ends of the main body 10 at the front and rear ends of the main body 10, and can effectively clean oil stains, welding slag adhered to the inner wall of the pipeline, pickling liquid and other impurities in the pipeline by scratching the pipeline, and the second sealing baffle 30 at the rear end plays a role of secondary cleaning, and the first sealing baffle 20 and the second sealing baffle 30 have high hardness and strong scratching ability, which can protect the main body 10 and make the main body 10 not easy to deform; a flexible central rod 40 is arranged in the main body 10, which enhances the overall strength of the foam pipe cleaner and can have a better cleaning effect, and the flexible central rod 40 is soft in texture, which can make the foam pipe cleaner have better passing ability when facing small diameter elbows to prevent them from getting stuck, and is more suitable for small diameter pipelines.

[0039] In this embodiment, the body 10 is composed of a truncated cone structure and a cylindrical structure. The cylindrical structure is arranged at the end of the truncated cone structure with a larger size, and the bottom surface size of the cylindrical structure is the same as the bottom surface size of the truncated cone structure. Specifically, the truncated cone structure is the front end of the body 10, which is buckled with the first sealing baffle 20, and the cylindrical structure is the rear end of the body 10, which is connected to the second sealing baffle 30.

[0040] Furthermore, a groove is provided on the first sealing baffle 20, and the shape of the groove fits the truncated cone structure of the body 10. The front end of the body 10 can be completely wrapped by the first sealing baffle 20, which increases the strength of the body 10 and prevents the body 10 from being damaged during use.

[0041] Furthermore, the size of the first sealing baffle 20 gradually decreases on one side near the end, so as to facilitate the foam pipe cleaner to enter the pipeline. Preferably, the outer shape of the first sealing baffle 20 is the same as the shape of the body 10 located at this end, and specifically, the outer shape of the first sealing baffle 20 is a combination of a truncated cone and a cylinder.

[0042] Furthermore, the second sealing baffle 30 is a cylindrical structure, and the size of the bottom surface is the same as the size of the connected body 10. The second sealing baffle 30 can perform secondary scraping cleaning on the inner wall of the pipeline, thereby improving the cleaning ability of the pipe cleaner.

[0043] In this embodiment, the two ends of the flexible central rod 40 are respectively provided with a first connection portion 41 and a second connection portion 42 for connecting with the first sealing baffle 20 and the second sealing baffle 30. Preferably, the first connection portion 41 is a cross-tenon block, and the second connection portion 42 is an external thread.

[0044] Furthermore, a cross groove 21 is provided in the first sealing baffle 20, which is adapted to the cross tenon groove. The cross groove 21 is a cross-shaped groove structure formed by digging again at the bottom of the groove. Specifically, the cross groove 21 is located on the central axis of the first sealing baffle 20. The cross groove 21 is arranged to cooperate and fix with the cross tenon groove, which is convenient for processing, and the cross-shaped structure can realize the positioning of the first sealing baffle 20 and the body 10 in two directions perpendicular to the axis, and can maintain a stable connection during use, avoiding rotation between the first sealing baffle 20 and the body 10.

[0045] Furthermore, the second sealing baffle 30 is provided with an internal thread 31 which matches with the external thread. Preferably, the internal thread 31 is arranged on the central axis of the second sealing baffle 30 .

[0046] In this embodiment, the maximum diameter of the first sealing baffle 20 and the second sealing baffle 30 is the same as the maximum diameter of the body 10. Therefore, the first sealing baffle 20 and the second sealing baffle 30 can protect the body 10 while also playing the role of scratching the inner wall of the pipeline. Similarly, the body 10 can also contact the inner wall of the pipeline to play the maximum cleaning role.

[0047] In this embodiment, the first sealing baffle 20 and the second sealing baffle 30 are preferably in interference fit with the inner wall of the pipeline, so that the first sealing baffle 20 and the second sealing baffle 30 can be in close contact with the inner wall of the pipeline, and the scraping cleaning effect is good. In addition, when in use, the first sealing baffle 20 and the second sealing baffle 30 can seal the fluid medium before and after the pipeline in the pipeline, generate a pressure difference through the fluid medium, and drive the foam pipe cleaner to move.

[0048] Preferably, in this embodiment, the first sealing baffle 20 and the second sealing baffle 30 are made of polyurethane, which is wear-resistant, aging-resistant, high in hardness and elastic, so that they can have an interference fit with the pipeline and have a good cleaning effect on stains with high viscosity and hard stains such as welding slag and metal debris.

[0049] In this embodiment, the flexible central rod 40 is preferably made of rubber or silicone, which is soft and has good resilience, and can cooperate with the foam pipe cleaner to pass through the curved pipe to prevent clogging.

[0050] In this embodiment, the foam pipe cleaner is suitable for cleaning small-diameter pipes, especially small-diameter industrial pipes with a diameter of less than 80 mm during the prefabrication process and after the construction is completed.

[0051] In this embodiment, the foam pipe cleaner can clean the disassembled pipeline or the whole pipeline that has not been disassembled, as long as a fluid medium can be transported behind the foam pipe cleaner to push the foam pipe cleaner forward. Preferably, the fluid medium is water.

[0052] The method of using the foam pipe cleaner for small-diameter pipelines provided by the utility model is as follows:

[0053] Place the foam pipe cleaner into the pipe to be cleaned, with the first sealing baffle 20 facing the inside of the pipe. The first sealing baffle 20, the main body 10 and the second sealing baffle 30 fit tightly against the inner wall of the pipe to isolate the pipeline in front of the first sealing baffle 20 and the pipeline behind the second sealing baffle 30. Transport the fluid medium behind the second sealing baffle 30 to push the foam pipe cleaner forward. The first sealing baffle 20 and the second sealing baffle 30 scrape and clean the inner wall of the pipe, and the main body 10 is used to absorb water stains in the pipe.

[0054] The utility model respectively arranges a first sealing baffle and a second sealing baffle at the front and rear ends of the main body at both ends of the main body, and can effectively clean oil stains, welding slag adhered to the inner wall of the pipeline, pickling liquid and other impurities in the pipeline by scratching the pipeline, and the second sealing baffle at the rear end plays a role of secondary cleaning, and the first sealing baffle and the second sealing baffle have great hardness and strong scratching ability, which can protect the main body and make the main body not easy to deform; a flexible central rod is arranged in the main body, which enhances the overall strength of the foam pipe cleaner and can have a better cleaning effect, and the flexible central rod is soft in texture, which can make the foam pipe cleaner have better passing ability when facing small diameter elbows and prevent them from being stuck, and is more suitable for small diameter pipelines.
