Pressure injection type plugging core cover of communication cable pipeline

Abstract

The invention discloses a pressure injection type plugging core cover of a communication cable pipeline, and belongs to the technical field of communication pipeline plugging. A plurality of pressure injection cylinders are embedded in an inner plugging plate, and the number of the pressure injection cylinders is in one-to-one correspondence with the number of cable cores in the communication pipeline; a plurality of groups of cable cores extend outwards through the elastic plugging bag one by one under the auxiliary limit of the cable auxiliary jacket, at the moment, a pouring opening in the top end part of the pressure injection cylinder is utilized to introduce a rubber material into the pressure injection cavity, the rubber material extrudes the elastic plugging bag after being introduced, and the extruded elastic plugging bag plays a very good role in pressing and attaching the cable cores on the inner side of the elastic plugging bag; and after the sizing material is solidified, mechanical connection between the elastic plugging bag and the cable core is realized, and the inner plugging plate is plugged and sealed by utilizing the matching of the main plugging ring positioned on the outer side of the top end of the inner plugging plate and the outer plugging plate, so that the mechanical strength of the plugging core cover is effectively improved, and the layer-by-layer embedded coating structure is not easy to be bitten by small animals or is not easy to age and damage for a short time due to weak mechanical strength.

Description

technical field [0001] The invention relates to the technical field of communication pipeline plugging, in particular to a pressure-injection type sealing core cover for communication cable ducts. Background technique [0002] The pipe blocker is a sealing device suitable for various cables and cable ducts. It eliminates the potential safety hazards caused by water seepage in the pipeline and small animals entering the pipeline and infringing on the cables. It protects the cables in the communication pipeline and extends the cables. service life effect. [0003] The existing cable duct plugging device adopts an inflatable type for sealing. Although the use of an inflatable structure for sealing is easy to operate, its mechanical strength is not good. When the inflatable part is bitten by a small animal or is damaged due to aging, the above-mentioned Hidden dangers; there are also products that use rubber structures. However, the fixed rubber structure is difficult to fit ti...

[0003] The existing cable duct plugging device adopts inflatable type for sealing. Although the use of inflatable structure for sealing is easy to operate, its mechanical strength is not good. When the inflatable parts are bitten by small animals or damaged due to aging, the above-mentioned Hidden dangers; there are also products that use rubber structures. However, the fixed rubber structure is difficult to fit tightly with the cable without gaps. The sealing effect is not particularly ideal, and the service life of the cable is reduced.
