Cable protection device capable of preventing overlarge tensioning force

Abstract

The invention discloses a cable protection device capable of preventing overlarge tensioning force, which relates to the technical field of power transmission cables. The device comprises cable connecting devices, a cable sliding device, a cable breaking and closing device and a cable, wherein two ends of the section of cable are fixedly connected with the cable connecting devices; the cable connecting device is fixedly connected with a connecting seat A in the cable breaking and closing device; a fixing seat in the cable breaking and closing device is fixedly mounted on the wire tower; the cable sliding device comprises a sliding rail and a limiting rod; the top of the sliding rail is hinged with the top of the wire tower; the bottom of the sliding rail is slidably connected with the limiting rod; the bottom end of the limiting rod is hinged to the bottom of the wire tower. One end of a sliding chain is in sliding fit with the peripheral surface of the sliding rail. Through the effects of the cable connecting device, the cable sliding device and the cable breaking and closing device, when extreme weather and wind speed early warning is carried out, what can be avoided is that thecable is broken due to the fact that the tensioning force is too large in the extreme weather, and the beneficial effects of protecting line safety and improving property safety guarantee are achieved.

Description

technical field [0001] The invention belongs to the technical field of power transmission cables, in particular to a cable protection device for preventing excessive tension force. Background technique [0002] The current power transmission cables are generally long in length, which results in a large weight load of the power transmission cables, and then requires relatively high strength of the cables. [0003] For example, when the wind speed in extreme weather is very high, the impact on the sway of the cable will make the tension of the transmission cable larger, and it is easy to cause a large damage to the transmission cable in a short time. impact, resulting in the phenomenon of breaking due to excessive tension, and the cable is easily injured when the line is thrown due to the break, and even the serious consequences of the collapse of the tower; all of which will cause property damage. serious loss. [0004] Aiming at the above-mentioned defects, the present inv...
