Problems solved by technology

[0003] At present, most of the techniques used to seal the cable protection nozzle on site are plugging mud, but there is no standard device in the pipe to support the plugging mud, which will cause the plugging mud to fall into the pipe over time, resulting in plugging failure. Therefore, it is necessary to A cable protection tube plugging device to solve this problem, so as to meet the requirements of protecting the safe and stable operation of cables

Abstract

The invention discloses a cable protection pipe plugging device. The plugging device comprises a cable pipe sleeve and a cable wire sleeve fixedly connected to an upper port of the cable pipe sleeve.The upper port of the cable wire sleeve is a cable wire outlet. A lower port of the cable pipe sleeve is a cable wire inlet. A cable enters into the plugging device from the cable wire inlet and penetrates out of the cable wire outlet. The invention relates to a full-sealed inverted funnel type sealing rubber device designed according to various types of cable protection diameters. Because of a rubber stretching characteristic, combination with an outer diameter of the cable can be achieved; installation is simple, construction is convenient, and an irreversible economic damage to a factory caused by potential danger and power failure is prevented; and a lifelong effect can be achieved, a specific size can be customized according to the diameter of the cable protection pipe, the device issuitable for various types of cable protection pipes, the device only needs to be buckled on a pipe for protecting the cable after wiring is completed, and the device can well solve a plugging problem of the cable protection pipe.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a plugging device for a cable protection tube. Background technique [0002] Power cables laid outdoors along poles or walls are generally protected by galvanized iron pipes or MPP pipes. Since the diameter of galvanized iron pipes or MPP pipes is more than 1.5 times the cable cross-section when considering the heat dissipation of the cables, the iron pipes are more than sufficient after the cables are laid through the pipes. In order to prevent rain, snow or small animals from entering the cable protection tube, the cable is usually blocked immediately after laying. [0003] At present, most of the techniques used to seal the cable protection nozzle on site are plugging mud plugging, but there is no standard device in the pipe to support the plugging mud, which will cause the plugging mud to fall into the pipe over time, resulting in plugging failure, so it is necessary to ...
