Abstract

The utility model discloses an OPGW cable rack structure multidirectional insulated guide clamp. The clamp comprises a U-shaped base, and turning mounting holes respectively arranged in the top plate and the side plate of the base and provided with a turning clamp head. The clamp is mounted on the position of an OPGW cable possibly contacted with a rack structure, enough safety distance between the OPGW cable and the rack structure is ensured, and the OPGW cable is not contacted with the rack structure under any circumstances, so as to avoid the discharge phenomena; and moreover the turning clamp head changes by 90 degrees on the base, so as to adapt to different installations.

Description

Lower clamp is drawn in the multidirectional insulation of a kind of OPGW optical cable framework
Technical field
The utility model relates to a kind of optical cable anchor clamps, and lower clamp is drawn in the multidirectional insulation of especially a kind of OPGW optical cable framework.
Background technology
From the early 1990s in last century so far, the OPGW optical cable has been set up in China's electric system on a large scale.Yet the OPGW damage repeatedly occurs in the transformer substation framework side in the OPGW optical cable in recent years, causes the optical fiber communication discontinuity events, has a strong impact on the communication network safe operation.Culprit is because OPGW optical cable downlead contacts with substation architecture ground wire metal support, when thunderbolt or line of electric force generation ground short circuit, ground current causes optical cable and framework contact position to produce potential difference (PD), cause OPGW optical cable and framework contact point place that arc discharge occurs, the high temperature that the arc discharge that continues produces causes the light unit to destroy the fusing of OPGW optical cable.Therefore, for the problems referred to above, be necessary to design a kind of special anchor clamps.
The utility model content
The technical problems to be solved in the utility model provides the multidirectional insulation that a kind of OPGW of preventing optical cable contacts with framework and draws lower clamp.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: lower clamp is drawn in the multidirectional insulation of a kind of OPGW optical cable framework, it is characterized in that: comprise the U-shaped base, respectively be provided with one on the top board of base and the side plate and turn to mounting hole, turn to and establish the chuck that turns to that annular is installed in the mounting hole.
Wherein, the base plate of described base is provided with puller bolt.
Wherein, the described chuck that turns to is annular, and its inside is provided with the insulating mat of annular.
Wherein, the described bottom that turns to chuck is provided with and turns to bolt.
Wherein, the described opening part of chuck that turns to is provided with fastening bolt.
The beneficial effect that adopts technique scheme to produce is: the utility model is installed in the position that OPGW optical cable and framework might come in contact on the shaft tower, puller bolt is used for base is fixed on shaft tower, the OPGW optical cable is through the insulating mat center, and utilize fastening bolt to be fixed on to turn in the chuck, guaranteed that OPGW optical cable and framework have the safe enough spacing, so that under any environmental baseline, OPGW optical cable and framework do not come in contact, to avoid the generation of electric discharge phenomena; And turn to chuck by turning to bolt, can install at base up conversion an angle of 90 degrees degree, to adapt to different installation occasions.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, puller bolt, 2, base, 3, turn to chuck, 4, insulating mat, 5, fastening bolt, 6, turn to bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Be illustrated in figure 1 as structural representation of the present utility model.The utility model is that lower clamp is drawn in the multidirectional insulation of a kind of OPGW optical cable framework, comprise U-shaped base 2, the base plate of base 2 is provided with puller bolt 1, respectively be provided with one on its top board and the side plate and turn to mounting hole, and turning to mounting hole is threaded hole, the chuck 3 that turns to of annular turns to bolt 6 to be installed in to turn in the mounting hole, turn to the insulating mat 4 that is provided with annular in the chuck 3, and its opening part is provided with fastening bolt 5 by what arrange in its bottom.
Operation instruction of the present utility model:
During use, the U-shaped opening of base 2 is sticked into shaft tower flange or angle steel place, realize and being fixedly connected with of shaft tower by the puller bolt 1 of rotating base 2 bottoms; According to the site operation needs, turn to chuck 3 to turn to bolt 6 by what be arranged on its bottom, can be installed in turning in the mounting hole on base 2 top boards, also can be installed in turning in the mounting hole on its side plate, realize 90 degree rotations; Then will turn to again the openend of chuck 3 to open, the OPGW optical cable will be passed from the center of insulating mat 4, at last the fastening bolt 5 of openend be tightened, realize that finally OPGW optical cable and shaft tower are in the insulation of mounting points.
