Embodiment
As shown in Figure 3, three cable pipeline 2 closeouts described in the utility model embodiment, comprise elastomer 1, the shape of described elastomer 1 all matches with the internal diameter of pipeline 2 with size, on described elastomer 1, be evenly provided with three cable aperture 4 that pass perpendicular to elastomer 1 and for current supply cable 3, the figure that the line in 4 centers of circle, adjacent cable hole forms is equilateral triangle, and described elastomer 1 is provided with 10 through holes 15 that are parallel to described cable aperture 4.
As Fig. 1, shown in 2, described elastomer 1 is arranged on inside and outside both sides on pipeline 2, and to be equipped with quantity be the pressing plate 14 of 3, described pressing plate 14 is evenly distributed on the outside of described cable aperture 4, described pressing plate 14 is arranged on elastomer 1 with cable aperture 4 is interlaced, the extension 12 of described pressing plate 14 is identical with the external diameter shape of elastomer 1 and be slightly less than the external diameter of elastomer 1, in described pressing plate 14, prolong 13 identical with the internal diameter shape of cable aperture 4 and be slightly larger than the internal diameter of cable aperture 4, for the extruding scope of maximized covering elastomer 1, make pressing plate 14 push the maximizing efficiency of elastomer 1.
Described pressing plate 14 position corresponding with described through hole 15 is provided with bolt hole, described bolt is from inside to outside successively through pad, pressing plate 14, elastomer 1 and outer plate 14 nut 5 matching with it that is threaded, tight a bolt, make inner-outer pressing plate 14 push elastomer 1, cause the external diameter of elastomer 1 and the part internal diameter of cable aperture 4 radially deformation occurs and expand, increase the pressure between elastomer 1 and pipeline 2 inwalls, also increase the pressure between cable aperture 4 and cable 3 simultaneously.
The through hole 15 of described bolt through described cable aperture 4 nut 5 that is threaded, between described bolt and elastomer 1, be provided with pad, because the elastomer 1 between cable aperture 4 is too narrow, therefore be not easy to arrange pressing plate 14, enough realize the extruding of the elastomer 1 between cable aperture 4 by the extruding of nut 6 and nut 5, there is radial expansion in Shi Gai district elastomer 1, increases the pressure between cable 3 and elastomer 1, realizes shutoff cable aperture 4.
As shown in Figure 4, described cable aperture 4 is furnished with the cable aperture 4 matching with it and fills in, described cable aperture 4 plugs comprise the round and elastic body 9 matching with cable aperture 4, the center of described round and elastic body 9 is provided with described through hole 15, the inside and outside both sides of described round and elastic body 9 are respectively equipped with circular clip plate 11 and circular outer plate 10, described circular clip plate 11 is equipped with described bolt hole with the center of circular outer plate 10, described bolt is from inside to outside successively through pad, circular clip plate 11, round and elastic body 9 nut 5 that is threaded with circular outer plate 10, the external diameter of described circular clip plate 11 is slightly less than the internal diameter of cable aperture 4, the external diameter of described circular outer plate 10 is slightly larger than the internal diameter of cable aperture 4.
As shown in Figure 5, described bolt hole is square through hole 15, described bolt comprises nut 6 and screw rod 7, between described nut 6 and screw rod 7, be provided with the spiral shell ridge 8 matching with described bolt hole, being shaped as of described spiral shell ridge 8 is square, when fastening nut 5 because square spiral shell ridge 8 match with bolt hole, prevent bolt rotate and cannot fastening nut 5.
As Fig. 1, shown in 2, when concrete use, first the pressing plate of both sides 14 is bolted to connection to elastomer 1, then cut open elastomer 1 with the internal diameter of two cable aperture 4 to the direction of elastomer 1 external diameter respectively with cutter, cut open elastomer 1 with cutter with the direction of three cable aperture 4 internal diameters of internal diameter to the of one of them cable aperture 4 simultaneously, then three cable aperture 4 are enclosed within respectively on three cables 3, then elastomer 1 being prolonged to cable 3 axial directions puts in pipeline 2 again, last fastening nut 5, make elastomer 1 radial expansion in pipeline 2, thereby increase the pressure between elastomer 1 and pipeline 2, also increase the pressure between elastomer 1 and cable 3 simultaneously, thereby realize the effect of sealing paired cable 3 pipelines 2.
When removing after cable 3, nut 5 is now threaded circular screw bolt passes clip plate 11, round and elastic body 9 with circular outer plate 10, thereby composition cable aperture 4 is filled in, because the external diameter of circular outer plate 10 is slightly larger than the internal diameter of cable aperture 4, therefore cable aperture 4 plugs are put into the rear automatic clamping master of cable aperture 4, last fastening nut 5, makes 9 radial expansions of round and elastic body, increase the pressure between round and elastic body 9 and elastomer 1, thereby realize shutoff cable aperture 4.
