Problems solved by technology
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.
And because it is underground for a long time, it is easy to infiltrate water vapor at the connection of the cable conduit, which will affect the cable

The invention discloses a cable guide pipe with sealing and dehumidifying functions. The cable guide pipe with the sealing and dehumidifying functions comprises a cable guide pipe body, wherein sealing units are arranged at openings of two ends of the cable guide pipe body; a humidifying unit is arranged in the cable guide pipe body; the sealing units are used for sealing the end port of the cableguide pipe body; each sealing unit comprises a sealing plate in threaded connection with the inner wall of the cable guide pipe body, a through hole formed in the sealing plate and used for a cable to penetrate through, and a sealing assembly arranged on the side wall of the through hole; each sealing assembly comprises an inflatable cushion arranged on the inner wall of each through hole in a surrounding way; each inflatable cushion is inflated to cover the cable; the dehumidifying unit comprises multiple humidity sensors arranged on the inner side wall of the cable guide pipe body, and dehumidifying assemblies in signal connection with the humidity sensors; the humidity sensors are also in signal connection with the inflatable cushions. The cable guide pipe with the sealing and dehumidifying functions provided by the invention at least has the following advantages of better sealing performance and dehumidifying performance, and optimized structure.
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. And because it is underground for a long time, it is easy to infiltrate water vapor at the connection of the cable guide, which will affect the cable. Contents of the invention [...
