Description

Technical Field

[0001] The utility model relates to the technical field of pipeline blocking, in particular to a novel cable pipeline blocking device. Background Art

[0002] At present, in the process of using cables, cable pipes are often used to protect the cables. Placing the cables in the pipes can well protect the cables from damage by small animals or other substances. However, there will be a gap between the cable and the side wall of the pipe at the interface connection between the cable and the pipe.

[0003] In order to avoid this problem, many manufacturers have designed and produced corresponding plugging devices. Most of the existing pipe pluggers use elastic rubber to make the inner pad of the pipe plugger. When the rubber is subjected to force, it expands inward and outward, filling the section between the pipe and the cable, thereby fixing the cable and achieving pipe sealing. For example, the Chinese utility model patent, application number 201920102196.3, is a plugging device for the gap between the cable and the pipeline, including an upper annular cover plate and a lower annular cover plate arranged in parallel, the upper annular cover plate and the lower annular cover plate have the same diameter, an annular rubber body is arranged between the upper annular cover plate and the lower annular cover plate, a fastening device is arranged between the upper annular cover plate and the lower annular cover plate, an annular cavity is arranged in the annular rubber body, the longitudinal section of the annular cavity is elliptical, and an annular groove is arranged on the opposite side of the upper annular cover plate and the lower annular cover plate, the longitudinal section of the annular groove is arc-shaped, the longitudinal section of the end of the annular rubber body is arc-shaped, and the free end of the annular rubber body is located in the annular groove, which solves the technical problems of the existing plugging device with complex structure and poor sealing effect. However, in actual use, since this type of occluder has only one layer of protection of elastic rubber, it will inevitably age over time, affecting the sealing effect and causing leakage.
