High voltage cable support protection device

Abstract

The invention discloses a high-voltage cable supporting protector. The high-voltage cable supporting protector includes a pedestal and support columns, wherein the support columns are hollow and are arranged horizontally by the central axis; the support columns include an upper cylinder and a lower cylinder which are symmetrical in design; the upper end surface of the lower cylinder is equipped with dovetails in the axial direction; the lower end surface of the upper cylinder is equipped with guide rails in the axial direction, and the guide rails are connected with the dovetails; each of theupper cylinder and the lower cylinder includes a cylinder outer wall and a cylinder inner wall; the cylinder inner wall of the upper cylinder is movably connected with the cylinder outer wall of the upper cylinder; the high-voltage cable supporting protector also includes a compaction structure; the compaction structure includes gears and screws; the screws penetrate through screwed holes and thenare rotatably connected with the cylinder inner wall of the upper cylinder; the gears are fixedly connected with gear shafts; the gear shafts are rotatably connected with the cylinder outer wall of the upper cylinder; soft shafts are connected between the gear shafts and the screws; a tooth bar is arranged on the cylinder outer wall of the lower cylinder; the length of the tooth bar is identicalto the axial length of the lower cylinder; and each gear is engaged with the tooth bar when the upper cylinder is connected with the lower cylinder. When the high-voltage cable supporting protector isarranged in a narrow pipe or obstructions exist around high voltage cables, the high-voltage cable supporting protector is convenient to mount and dismount.

Description

technical field The invention belongs to the technical field of high-voltage cable installation equipment, and in particular relates to a high-voltage cable support and protection device. Background technique High-voltage cables are power cables used to transmit 1KV-1000KV voltage. At present, the main laying methods include buried and overhead lines. The laying of high-voltage cables in suburban or less populated areas mainly adopts overhead lines. Because the buried type occupies less land, beautifies the city and has good security and concealment, when the high-voltage cables enter the big cities, the overhead lines are often transferred to the buried type, and some protective devices are needed when the overhead line connecting cables enter the ground surface. The cable is protected, but the existing protection device has problems such as inconvenient installation and disassembly due to its large size. In order to solve the above problems, the Chinese invention patent ...
