Abstract
The utility model discloses an aerial optical cable leading down sealing protection device which comprises a sealing waterproof rubber tape wound around a guide optical cable at the outlet of a pre-buried steel pipe. A protection sheath is arranged outside the sealing waterproof rubber tape. A first steel hoop is arranged at the position, which is near the upper end, of the protection sheath. A second steel hoop is arranged at the position, which is near the lower end, of the protection sheath. A half type split structure design is used. A casing body is fixed by double plastic buckles and can be assembled or disassembled in a few of seconds. A joint can be completely isolated from the external environment. The possibility of moisture condensation is eliminated. The electrical performance of the optical cable and the joint can be improved. Vibration caused by a wind load or a vibration force can be effectively reduced, so as to keep the torque of the joint. The device passes a waterproof test and has the advantages of simple assembly and disassembly. The high-altitude operation time of an operator is greatly shortened, which makes assembly and disassembly secure.
Description
Technical field
The utility model relates to lightguide cable link shutoff field, relates in particular to a kind of aerial optical cable and draws the lower seal protective device.
Background technology
At present, traditional fire prevention mudding plugging technique, the mudding of directly preventing fires gets lodged in the embedded steel tube exit, because anti-chamotte is exposed in air for a long time, often occur dry and cracked, the phenomenon such as shutoff is not tight, cause embedded steel tube weld ponding, run into severe cold weather and often cause the optical cable frostbite, cause Cable's Fault, the safety of optical cable in serious threat.
The utility model content
The deficiency that exists for solving prior art; the utility model specifically discloses a kind of aerial optical cable and draws the lower seal protective device, adopts Hafu type to split structural design, and housing is fixed for two plastic lock catch; several seconds can complete installation or removal, and it has waterproof, anti-icing, insulation advantage.
For achieving the above object, concrete scheme of the present utility model is as follows:
A kind of aerial optical cable draws the lower seal protective device, comprises the water-tight rubber adhesive tape, and water-tight rubber adhesive tape outside is provided with the protection sheath, and the protection sheath is provided with the first stirrup near upper end, and the protection sheath is provided with the second stirrup near lower end;
Described water-tight rubber adhesive tape is arranged on the guiding optical cable in embedded steel tube exit;
Built-in two the elastic water-proof Rubber washers in described protection sheath top;
The structure of described protection sheath be Hafu type to opening structure, the housing of protection sheath be the housings that two plastic lock catch are fixed.
In the place's shutoff of the embedded steel tube mouth of pipe, prevent on a small quantity chamotte, stirrup is fixed for confining the protection sheath, makes to protect sheath and guiding optical cable, embedded steel tube to accomplish seamless link.
The beneficial effects of the utility model:
1 agility: adopt Hafu type to split structural design, housing is fixed for two plastic lock catch, and the several seconds can complete installation or removal.
2 reliabilities: joint and external environment condition can be isolated fully, eliminate the possibility that moisture condenses, improve the electric property of optical cable and joint, can effectively slow down by the vibrations that wind carries or vibration force causes, to keep the moment of torsion of joint, pass through waterproof test.
3 securities: loading and unloading are simple, greatly shortened the time of operating personnel's work high above the ground, make installing/dismounting work safer.
The accompanying drawing explanation
Fig. 1 scheme of installation of the present utility model;
Fig. 2 installation figure of the present utility model;
In figure, 1 guiding optical cable, 2 first stirrups, 3 second stirrups, 4 water-tight rubber adhesive tapes, 5 protection sheaths, 6 anti-chamotte, 7 embedded steel tubes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1-2, a kind of aerial optical cable draws the lower seal protective device, comprise the water-tight rubber adhesive tape 4 on the guiding optical cable 1 that is filled in embedded steel tube 7 exits, there is protection sheath 5 water-tight rubber adhesive tape 4 outsides, protection sheath 5 is provided with the first stirrup 2 near upper end, and protection sheath 5 is provided with the second stirrup 3 near lower end;
Built-in two the elastic water-proof Rubber washers in described protection sheath 5 tops;
Described protection sheath 5 be Hafu type to opening structure, the housing of protection sheath 5 be the housings that two plastic lock catch are fixed.
In embedded steel tube 7 mouth of pipe place shutoff, prevent on a small quantity chamotte 6; on guiding optical cable 1, fill water-tight rubber adhesive tape 4; water-tight rubber adhesive tape 4 outsides install protection sheath 5 additional; built-in two elastic water-proof Rubber washers sealing on protection sheath 5 tops; with the first stirrup 2 and the fixing protection sheath 5 of the second stirrup 3, make to protect sheath 5 and guiding optical cable 1, embedded steel tube 7 to accomplish seamless link.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
