Problems solved by technology

[0002] In the prior art, such as the Chinese patent application, the application number is: 201420759964X, and the patent name is: cable duct plugging device, which squeezes and expands the seal by compressing the flexible seal provided between the two pressure plates , to achieve the sealing of the cable duct; however, during the compression process, the deformation direction of the seal is uncertain, which will eventually result in poor sealing of the cable duct
Especially the sealing effect between the sealing member and the cable is poor, because the surface of the cable is irregular or there are small gaps, etc., the existing occluder has a poor sealing effect between the sealing member and the cable and the pipeline during the sealing process. The pressure cannot reach the level that can completely seal small gaps and irregular surfaces, so the sealing performance is poor

Embodiment 1

[0017] Such as figure 1 As shown, a cable duct sealing device described in this embodiment includes an annular first pressing plate 1, an annular second pressing plate 3 and a rubber member 2 arranged between the first pressing plate 1 and the second pressing plate 3, The rubber part 2 is an annular structure, and one of them is provided with an opening 8, such as figure 2 As shown, the rubber part 2 includes an annular top wall 4, an annular outer side wall 5 and an annular inner side wall 6, the upper ends of the outer side wall 5 and the inner side wall 6 are connected to the top wall 4, and the outer side wall 5 and the inner side wall 6 are connected to each other. There is a gap between them, and a plurality of connection holes 7 are arranged at intervals on the top wall 4 between the outer side wall 5 and the inner side wall 6, and a plurality of connection holes 7 are respectively arranged on the first pressure plate 1 and the second pressure plate 3 corresponding to ...

Abstract

The invention relates to the field of pipeline plugging equipment, particularly a cable pipeline plugging apparatus. The cable pipeline plugging apparatus comprises an annular first pressing plate, an annular second pressing plate, and a rubber part arranged between the first pressing plate and the second pressing plate; the rubber part adopts an annular structure, and an opening is formed in one position thereof; each of the first pressing plate and the second pressing plate is formed by two semi-annular structures separately; and the first pressing plate, the second pressing plate and the rubber part are fixedly connected through threaded rods and nuts. According to the cable pipeline plugging apparatus obtained in the invention, by virtue of compression of the first pressing plate and the second pressing plate, the outer side wall of the rubber part can be extruded to be convex outwards; and meanwhile, by virtue of the design of the inclined inner wall of the second pressing plate, the inner side wall of the rubber part can be compressed inwardly, so as to generate relatively high pressure between the inner side wall of the rubber part and the cable, so that better sealing performance is achieved.

Description

technical field [0001] The invention relates to the field of pipeline sealing equipment, in particular to a cable pipeline sealing device. Background technique [0002] In the prior art, such as the Chinese patent application, the application number is: 201420759964X, and the patent name is: cable duct plugging device, which squeezes and expands the seal by compressing the flexible seal provided between the two pressure plates , to realize the sealing of the cable duct; however, during the compression process, the deformation direction of the sealing member is uncertain, which will eventually result in poor sealing of the cable duct. Especially the sealing effect between the sealing member and the cable is poor, because the surface of the cable is irregular or there are small gaps, etc., the existing occluder has a poor sealing effect between the sealing member and the cable and the pipeline during the sealing process. The pressure cannot reach the level of sealing all the ...
