Cable conduit with good sealing effect

Abstract

The invention discloses a cable conduit with a good sealing effect. The cable conduit comprises a cable conduit body and a sealing unit, wherein the sealing unit comprises a sealing plate, a through hole, a clamping assembly and a sealing assembly; the sealing plate is in threaded connection to an inner wall of the cable conduit, the through hole is formed in the sealing plate and used for the a cable to penetrate through, and the clamping assembly and the sealing assembly are arranged on a lateral wall of the through hole; the clamping assembly comprises a plurality of pieces of clamping plates which are annularly arranged on an inner wall of the through hole, the first end of each clamping plate is fixedly connected to the inner side of the inner wall of the through hole, the second endof each clamping plate extends in the axial direction of the through hole and is gradually close to a through hole axis drifting device; the sealing assembly comprises an inflation cushion which is annularly arranged in a gap formed by the clamping plates and the through hole, the inflation cushion is inflated to extrude the clamping plates until the clamping plates move close to the through holeaxial direction to abut against the cable, and the cable is wrapped by the inflation cushion. The cable conduit disclosed by the invention at least has the following advantages of better sealing performance, ability in better fixing the cable and ability in performing structure optimization on the cable.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a cable guide with good sealing effect. Background technique [0002] Cable conduit is a protective part popularized and used in electric power engineering. It is used to protect wires and cables in electrical installations, allowing the penetration and replacement of wires and cables. At present, the waterproofing of cable trenches and cable wells mainly uses cement, plugging mud and other materials to seal the cable pipes, but the water blocking effect is not good. Waterproof effect. In addition, daily cable maintenance operations will inevitably damage the sealing material at the cable tube, which needs to be resealed, which is inconvenient for future electrical replacement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable guide with good sealing effect, which has good sealing performan...
