Embodiment Construction

[0014] The enclosed optical cable tray includes a cross 1 and a cylindrical shield 6. The four ends of the same side of the cross 1 are fixed with a straight plate 2 perpendicular to the surface where the cross is located. The ends of 2 are all forked, and a part of the fork is bent 90 degrees toward the center of the cross to form an inner bend 3, and the other part of the fork is bent away from the center of the cross to form an outer bend 5, and the inner bend 3 is opened There are screw holes 4, and the bottom surface of the cylindrical shield 6 is provided with a screw hole 4 corresponding to the screw hole on the inner curved piece 3, and the diameter of the opening of the cylindrical shield 6 is greater than any linear distance relative to the end of the outer curved piece. Have inlet 8 and outlet on the tube wall at the opening of shaped shield 6.

[0015] For the above-mentioned closed type optical cable reel holder, the cylindrical shield 6 is made by stamping steel ...

Abstract

The invention relates to a device for coiling and retaining a power communication optical cable, in particular to an enclosed type optical cable coiling and retaining frame. The enclosed type optical cable coiling and retaining frame comprises a cross and a cylindrical protective cover. Four ends of the same side of the cross are respectively and fixedly provided with a straight panel perpendicular to the plane where the cross is located. The panel surfaces of the straight panels at the opposite positions are opposite. The end of each straight panel is branched, wherein one branch is bent 90 degrees towards the center of the cross to form an inward bent piece, the other branch is bent in the direction deviating from the center of the cross to form an outward bent piece, and each inward bent piece is provided with a threaded hole. The bottom face of the cylindrical protective cover is provided with threaded holes corresponding to the threaded holes formed in the inward bent pieces. The opening diameter of the cylindrical protective cover is larger than the linear distance between the ends of any two opposite outward bent pieces. Through the enclosed type optical cable coiling and retaining frame, the optical cable coiled and retained on the cross can be covered with the cylindrical protective cover, the optical cable can not be damaged accidentally, and the optical cable can not be damaged when a cable joint is ignited in the detonation process; thus, the enclosed type optical cable coiling and retaining frame can effectively protect the power communication optical cable.

Description

technical field [0001] The invention relates to a device for reeling power communication optical cables, in particular to a closed type optical cable reel rack. Background technique [0002] The power communication optical cable is laid along with the cables in the power tunnel or power pipe. In the cable inspection well for maintenance and repair, the optical cable needs to be welded after the fault is interrupted. Therefore, the optical cable must be redundant, and the redundant optical cable is stored on the optical cable tray. , and be fixed on the wall of the inspection well, and the existing optical cable tray is an open structure, which has poor anti-collision damage and fire resistance, and cannot effectively protect the optical cables existing thereon. Contents of the invention [0003] In order to solve the problem that the existing open optical cable reel shelf cannot effectively protect the power communication optical cables existing thereon, the present invent...
