Description

TECHNICAL FIELD

[0001] The utility model relates to cable sealing field, specifically, relate to a big diameter single cable modularization reducing seal device. BACKGROUND

[0002] With the development needs of social construction, more and more industries continuously improve the demand for electrification, and the cable consumption and sealing demand gradually increase.

[0003] Cable inevitably passes through structural parts in use, and there is a gap between the structural opening and the cable. For large diameter cables, the current sealing element with a peelable core is used to achieve sealing of pipelines with different diameters by peeling the core. The patent with application number CN201510897008.7 discloses a variable-diameter sealing module, which includes two elastic outer shell halves. A semicircular groove is provided in each elastic outer shell half. An elastic body sheet layer covers the groove. The elastic body sheet layer is composed of multiple layers of peelable elastic body sheets. The upper and lower surfaces of each layer of peelable elastic body sheets are respectively provided with convex structures and concave structures. The width of the convex structure matches the width of the concave structure, and the height of the convex structure matches the depth of the concave structure. The convex structures and concave structures of adjacent two layers of peelable elastic body sheets are embeddedly connected. After the two elastic outer shell halves are connected, a circular through hole is formed inside, which can be used for passing cables or pipelines. Although this patent can seal the gap between cables with different diameters and structures, this sealing structure cannot adapt to sealing devices with different cable diameters. When the cable needs to be replaced, the sealing element with a peeled core needs to be re-adapted to the new cable. Especially in the case of a new cable with a smaller diameter, the missing core layer of the sealing element also needs to be replaced with a new sealing element, causing resource waste. In addition, the sealing effect is poor.

[0004] Therefore, the utility model is proposed. UTILITY MODEL CONTENT
