A cement groove for preventing the cable of the upper pole from breaking outside

Abstract

The invention relates to a cement tank used for preventing damage of upper pole cable by external force, belonging to the technical field of operation and maintenance of power distribution lines. Thecement groove includes underground cable wells, one end of the cable work well communicates with a cable drain pipe, the other end communicates with the cable tray, one end of the cable slot extends to the pole, The cable drain pipe and the cable slot are both hollow structures with openings at both ends. The lower surface of the cable slot is designed as a ramp. The height of the lower surface ofthe cable slot near one end of the pole is higher than that of the lower surface of the cable slot near one end of the cable well. The pole is also provided with a cable pipe. The top of the cable pipe is located above the ground and the bottom is connected with the cable slot. The cement groove not only can effectively protect the cable buried directly to the cable pipe by exposing the root of the pole and bending underground, but also can flexibly repair and replace the cable, save time and labor, greatly improve the working efficiency of the working personnel on the spot, and is safe and reliable.

Description

technical field [0001] The invention designs a cement tank for preventing the external force damage of upper rod cables, and belongs to the technical field of power grid distribution line operation and maintenance. Background technique [0002] Cable conduit is a kind of conduit used to protect cables when laying cables. It can provide paths and enough space for cables to be buried underground, and provide protection for cables. When the cable passes through the discharge pipe and goes up the pole, the existing technology for putting the cable on the pole is generally to bury the underground part of the cable directly. When the cable is close to the pole, the cable is bent and then put on the pole. These two methods have great potential safety hazards. [0003] At present, the common way to protect the cables on the upper pole is to install a cable guard at the root of the pole. Since the cable guard can only provide protection for the cables on the pole, the root of the po...

When the cable passes through the discharge pipe and goes up the pole, the existing technology for putting the cable on the pole is generally to bury the underground part of the cable directly. When the cable is close to the pole, the cable is bent and then put on the pole. There are great safety hazards in these two ways

[0003] At present, the common way to protect the cables on the upper pole is to install a cable guard at the root of the pole. Since the cable guard can only provide protection for the cables on the pole, the root of the pole is exposed and bent underground, and it is directly buried to the cable pipe. The part cannot provide effective protection, and when there is excavation construction near the pole, due to the existence of cables that have not penetrated through the pipe and are directly buried, the excavation machinery of the construction party is easy to damage this part of the cable, resulting in short-circuit tripping of the line. There have been accidents where the upper pole cables were not effectively protected and were damaged by construction, causing the entire line to trip and cause a large-scale power outage. Moreover, when some cables passing through the cable pipes need to be repaired and replaced, the construction excavation is not only cumbersome. , but also time-consuming and laborious, low work efficiency and high cost. If there are other cables near the direct burial of the upper pole cable, unreasonable excavation may accidentally damage the nearby cables, and the safety factor is low.
