The device comprises an intelligent excess length control device body and is characterized in that the intelligent excess length control device body is provided with a temperature reduction water tank, a support, a water storage tank, a tractor and a main control cabinet, wherein a bottom portion of the temperature reduction water tank is fixed on an upper surface of the support, a bottom end of the support is fixed on the ground, the temperature reduction water tank is provided with a protection cover and a through tube hole, the protection cover is connected with an inner side wall of the temperature reduction water tank through a hinge, the through tube hole is mounted at the middle portion of left and right sides of the temperature reduction water tank, the water storage tank is mounted at the gap of the support on the ground, the tractor is mounted behind the support and is fixed on the ground, and the main control cabinet is mounted on the ground. The device is advantaged in that a field use result indicates that the structure is simple and reliable in design, precise system control is realized, the three-level temperature reduction water tank is utilized to cool the beam tube, a cooling speed of the beam tube is controlled through the tractor, excellent matching is realized, automatic fiber excess length control is realized, and the device is suitable for popularization and application.

Description

Technical field [0001] The invention relates to the technical field related to the manufacture of optical fibers and cables, in particular to a fully automatic adjustment device for the excess length of the optical fiber for a bundle tube. Background technique [0002] The fiber bundle tube is the main component of optical cables such as ADSS and flame-retardant cables. The excess length of the fiber in the bundle tube will affect the quality and life of the optical cable itself. When the excess length is too long, not only the fiber is wasted, but the entangled fiber will The inner wall of the bundle tube is directly rubbed, which increases the loss of optical signal transmission and reduces the service life; if the excess length is too small, when the optical cable is slightly bent or stretched, the fiber inside will be stressed, and the stressed fiber will transmit optical signals The phenomenon of high distortion rate and unstable signal transmission damages the optical fiber...

Problems solved by technology

[0002] Optical fiber bundle tube is the main component of ADSS, flame-retardant cable and other optical cables, and the excess length of the optical fiber in the bundle tube will affect the quality and life of the optical cable itself. Direct friction occurs on the inner wall of the bundle tube, which increases the transmission loss of optical signals and reduces the service life; when the excess length is too small, when the optical cable is slightly bent or stretched, the optical fiber in it will be stressed, and the optical signal will be transmitted on the stressed optical fiber The phenomenon of high distortion rate and unstable signal transmission will damage the optical fiber and shorten the service life
