Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of Novel underground fiber cable cross connection box, comprise casing 2, casing 2 is placed in the underground space 1, and the underground space 1 comprises opening 11, opening 11 is provided with Sealing shield ring 5, casing 2 is arranged with bracing or strutting arrangement, and bracing or strutting arrangement comprises brace table 8, brace table 8 is provided with support frame 9, casing 2 is placed on support frame 9, and casing 2 is not fixedly connected with support frame 9.
Casing 2 is fixedly installed heat abstractor 3, heat abstractor comprises heat dissipation tank 3, casing 2 inside is communicated with heat dissipation tank 3, heat dissipation tank 3 is fixedly installed the seal cover board 4 matched with Sealing shield ring 5, toroidal membrane 31 is provided with in heat dissipation tank 3, toroidal membrane 31 is divided into heat dissipation tank 3 into headroom 32 and air outlet space 33, heat dissipation tank 3 outer wall is provided with several air intake vents 34, air intake vent 34 is communicated with into headroom 32, bending ventilation duct 47 on air outlet space 33 communication seals cover plate 4, is provided with fan 35 in air outlet space 33.Be provided with grid division board 48 in bending ventilation duct 47, grid division board 48 is provided with hydrophobic permeable membrane.Bending ventilation duct 48 slides and is provided with gland bonnet 44, gland bonnet 44 top is circular arc, gland bonnet 44 is provided with the sealing gasket 46 matched with seal cover board 4, and gland bonnet 44 is connected with seal cover board 4 by flexible fastening silk simultaneously.Seal cover board 4 is provided with first annular sealing strip 43, Sealing shield ring 5 is provided with the second annular sealing strip 51 agreed with mutually with described first annular sealing strip 43, space is left between casing 2 and the underground space 1 sidewall, admission passage 12 and leaving channel 13 is provided with in the underground space 1, admission passage 12 is provided with several first rolling wheels 6, leaving channel 13 is provided with several second rolling wheels 7, groove 14 is provided with inside opening 11, seal cover board 4 is movably set with the card column 41 matched with groove 14, described seal cover board 4 is provided with the keyhole 42 controlling card column 41.
When needing maintenance, only need staff by keyhole 42 card column 41 to be exited from groove 14 and just can take out whole device, in order to prevent optical cable from getting loose while taking-up, need longer cable line, these longer cable lines just can be wound on first rolling wheel 6 on admission passage 12 and leaving channel 13 and second rolling wheel 7, prevent that cable line is rambling to be wrapped in the underground space 1.
