An optical fiber s-shaped swing device and a production method for a high-voltage optical fiber composite cable

Abstract

The invention discloses an optical-fiber S-shaped pendulous device and a production method for a high-voltage optical-fiber composite cable. The optical-fiber S-shaped pendulous device includes a plurality of wrapping-tape guide rods which are arranged to be surrounding a cable. A wrapping tape is wrapped on the cable through the wrapping-tape guide rods. A friction wheel, which is attached on the cable closely and moves with the traveling of the cable, is arranged on the outer periphery side of the cable. A swing arm is arranged on the outer periphery side of the cable. An optical fiber passes through a die hole at the rear end of the swing arm. Moreover, the invention also provides a method for producing the high-voltage optical-fiber composite cable through use of the optical-fiber S-shaped pendulous device. The cable moves forwards and drives the friction wheel to rotate. The friction wheel drives the swing arm to swing through a gear transmission mechanism and a swing-arm driving mechanism. The optical fiber is attached on the surface of the cable in an S-shape through the die hole in the swing arm and at the same time, the wrapping-tape guide rods rotate in a counterclockwise manner. The wrapping tape is wrapped on the cable after passing the wrapping-tape guide rods and then the optical fiber is fixed on the surface of cable in an S-shape. The optical-fiber S-shaped pendulous device and the production method for the high-voltage optical-fiber composite cable reduce the work intensity of operators significantly and improve efficiency by dozens of times and the formed S-shape is significantly regular and tidy and effect is greatly ideal.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a production method of a high-voltage optical fiber composite cable and a corresponding production device. Background technique [0002] The high-voltage optical fiber composite cable uses the temperature-measuring optical fiber laid inside or close to its surface to realize real-time online monitoring of the temperature of the high-voltage cable. The requirement is to attach one or two temperature-measuring optical fibers to the outside of the cable insulation layer. Due to the large diameter of the cable, when the cable is bent, the outer length will be elongated. Therefore, when attaching the optical fiber to the cable, the optical fiber must be attached to the surface of the cable in an S shape, so as to ensure that the optical fiber will not be pulled off at any time. [0003] The optical fiber composite production method is at the front end of the buffer tape wrapping. A...

AI Technical Summary

Problems solved by technology

[0004] Since the optical fiber is artificially arranged in an S shape, glued firmly with adhesive tape, and then wrapped around the tape, the defect is that the efficiency is low, the labor intensity of the operator is high, the S shape is irregular, and the effect is not ideal.

Moreover, if the joint of the semi-conductive buffer belt is encountered, it is necessary to paste the upper and lower layers of the tape. This manual operation method also has potential safety hazards.
