Description
Technical field
The utility model relates to OPGW optical cable in a kind of transformer station and draws lower optical cable Anti-freezing structure.
Background technology
At present, the Anti-freezing measure that transformer station's OPGW optical cable draws lower guiding fiber cable laying is not sought unity of standard and requirement, and classic method mainly through by optical cable overcoat PVC hard tube, penetrates coating steel pipe under the drawing of framework, after stretch into sand pit direct-burried steel pipe, finally do waterproof shutoff drawing lower PVC hard tube top.Outside waterproof plugging material is chronically exposed to, the phenomenons such as easy generation loosens, cracking, rainwater is caused to infiltrate in PVC hard tube from waterproof shutoff, rainwater directly can infiltrate framework coating steel pipe and direct-burried steel pipe joint by sand pit simultaneously, flow in pvc pipe butt seam, cause producing ponding around guiding optical cable, ice up in winter expands and causes optical cable to be out of shape to optical cable severe crush, causes the power communication accident of interruption of optical cables.
Utility model content
The purpose of this utility model is to provide OPGW optical cable in a kind of transformer station and draws lower optical cable Anti-freezing structure, can prevent the optical cable distortion caused because ponding is freezing.
In a kind of transformer station, OPGW optical cable draws lower optical cable Anti-freezing structure, comprise transformer substation framework shaft tower, its special feature: be provided with remaining cable frame in the middle of described transformer substation framework shaft tower, transformer substation framework shaft tower above this remaining cable frame is provided with top coating steel pipe and transformer substation framework shaft tower below remaining cable frame is provided with bottom coating steel pipe, the bottom of this bottom coating steel pipe is stretched into underground and is also provided with direct-burried steel pipe in the underground that this bottom is other, and this direct-burried steel pipe stretches in the cable duct of underground; Also comprise flexible plastic tube, the top of this flexible plastic tube is coiled on aforesaid remaining cable frame and this top down, and the bottom of this flexible plastic tube is stretched in cable duct through after bottom coating steel pipe, direct-burried steel pipe successively.
Wherein on transformer substation framework shaft tower, fibre-optical splice box is installed.
Wherein be wound with adhesive waterproof tape on the top of flexible plastic tube.
Wherein flexible plastic tube adopts PE plastic tube.
The beneficial effects of the utility model are, are laid by an overall flexible PE plastic tube, efficiently solve rainwater and are connected the problem seeped water in pipe at gap place by conventional P VC hard tube.PE plastic tube leaves surplus at remaining cable frame place, can with OPGW optical cable with guiding reel on remaining cable frame, the mouth of pipe of PE plastic tube down, solves because waterproof shutoff is aging, loosening, ftractures, and causes rainwater to enter ponding in pillar and to freeze the generation of situation.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is that in a kind of transformer station, OPGW optical cable draws lower optical cable Anti-freezing structure, comprise transformer substation framework shaft tower 1, remaining cable frame 3 is provided with in the middle of described transformer substation framework shaft tower 1, transformer substation framework shaft tower 1 above this remaining cable frame 3 is provided with top coating steel pipe 8 and transformer substation framework shaft tower 1 below remaining cable frame 3 is provided with bottom coating steel pipe 7, the bottom of this bottom coating steel pipe 7 is stretched into underground and is also provided with direct-burried steel pipe 5 in the underground that this bottom is other, and this direct-burried steel pipe 5 stretches in the cable duct 6 of underground; Also comprise flexible plastic tube 4, the top of this flexible plastic tube 4 is coiled on aforesaid remaining cable frame 3 and this top down, and the bottom of this flexible plastic tube 4 is stretched in cable duct 6 through after bottom coating steel pipe 7, direct-burried steel pipe 5 successively.
Wherein on transformer substation framework shaft tower 1, be provided with fibre-optical splice box 2, be wound with adhesive waterproof tape on the top of flexible plastic tube 4, flexible plastic tube 4 can adopt PE plastic tube in addition.
Using method of the present utility model is:
As shown in Figure 1, a flexible PE plastic tube of entirety lays from cable duct 6, penetrate in the direct-burried steel pipe 5 at cable duct 6 to framework shaft tower 1 place, then penetrate framework to draw to remaining cable frame 3 place in lower coating steel pipe (i.e. bottom coating steel pipe 7), and reserve the surplus can coiling Gu2Quan at remaining cable frame 3 herein; The guiding optical cable passed in top coating steel pipe 8 is penetrated in flexible PE plastic tube, after completing framework place optical cable welding, by PE plastic tube with transformer station OPGW optical cable, guiding reel admittedly on remaining cable frame 3, and adjust PE plastic tube length and make the mouth of pipe of plastic tube (namely towards ground) down, guarantee that rainwater etc. cannot enter PE plastic tube top.And do at the port adhesive waterproof tape on PE plastic tube top and be wound around protection, prevent port from damaging optical cable.
