Description

Technical Field

[0001] The utility model relates to the technical field of embedded pipelines, in particular to a pipeline orifice sealing device for embedded pipelines. Background Art

[0002] With the development of China's power industry, pipeline embedding has become the development trend of the laying of power cables and communication optical cables. During the construction of cable pipelines, it is often necessary to penetrate walls, and holes need to be reserved according to construction requirements, and the reserved pipelines need to be blocked to ensure the smooth progress of subsequent project construction. Existing sealing devices all block the pipeline orifice with components. Such devices are generally made of metal and are difficult to change in size. To adapt to different pipe diameters, different sizes of sealing devices are required, which easily causes problems such as mismatch or incomplete sealing.

The utility model relates to the technical field of embedded pipelines, in particular to a pipeline orifice plugging device for embedded pipelines, which includes a plugging seat and a fixing mechanism. The fixing mechanism includes a locking assembly connected to the plugging seat and a telescopic assembly for abutting and cooperating with the inner wall of the pipeline. The telescopic assembly includes a first connecting rod, a second connecting rod, and at least two abutting blocks circumferentially arranged around the locking assembly. The two ends of the first connecting rod are respectively hinged to the abutting block and the locking assembly; the two ends of the second connecting rod are respectively hinged to the abutting block and the locking assembly. Adjusting the angle between the first connecting rod and the second connecting rod can adjust the distance between the abutting block and the locking assembly. The plugging seat can be used to close the pipeline orifice of the embedded pipeline. During installation, the telescopic assembly is inserted into the pipeline, and then the telescopic assembly is adjusted through the locking assembly. The telescopic assembly abuts against the pipeline, so as to stably fix the plugging seat at the pipeline orifice of the embedded pipeline. The disadvantage of this utility model is that it cannot adapt to the internal sizes of various pipelines and is prone to incomplete sealing. Summary of the Utility Model
