Tension self-tightening device for outdoor cable

Abstract

The invention provides a tension self-tightening device for an outdoor cable. The device comprises a shell, a base is arranged at the bottom of the shell, a protective shell is installed on the front face of the shell through bolts, a self-locking forward and reverse rotation motor is installed on the front face of the shell through bolts, a winding roller is rotationally connected to the interior of the shell, one end of the winding roller is connected to the self-locking forward and reverse rotation motor, and limiting discs are welded to the two sides of the winding roller correspondingly; and a clamping frame is arranged at one sides of the limiting discs, a supporting rod is arranged in the shell, a tension sensor is arranged at the top of the supporting rod, a first controller is installed in the shell, and a positioner is arranged at the top of the first controller. The tension state of the cable can be conveniently adjusted through the device, a worker can conveniently know the close state of the cable, the worker can conveniently remotely operate the tension self-tightening device, the worker can conveniently know the position of the tension self-tightening device, the exterior of the cable can be wiped, and impurities outside the cable are prevented from entering the tension self-tightening device.

Description

technical field [0001] The invention specifically relates to the technical field of outdoor cables, in particular to a tension self-tightening device for outdoor cables. Background technique [0002] Cable is a kind of electric energy or signal transmission device, usually composed of several or several groups of wires, cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables , Marine cables, mining cables, aluminum alloy cables and so on. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the system of the photovoltaic power station. The tension self-tightening device is required when the cable is used. [0003] The cable tension tightening device in the prior art has the following problems: it is inconv...
