Abstract

The invention discloses a protection device for buried transmission lines, which includes a buried box buried underground, and a protective shell that can move in the buried box and is used to accommodate cables is provided in the buried box. The surface of the shell is provided with a metal protective column that is in contact with the external barrier. When the external barrier is pressed on the metal protective column, the metal protective column drives the protective shell to avoid one side through the avoidance of its circular surface, thereby avoiding protection. The shell is broken by an external barrier. When an external barrier such as an excavator digs into the buried box, the bucket of the excavator first touches the surface of the metal protection column. Due to the round surface of the metal protection column, the metal protection column will The surface of the bucket moves, thereby driving the protective shell to move toward the side of the buried box for avoidance, preventing the cables inside the protective shell from being cut by the bucket of the excavator, which plays a good protective role.

Description

technical field

[0001] The invention relates to the technical field of buried transmission lines, in particular to a protection device for buried transmission lines. Background technique

[0002] Buried transmission lines are transmission line equipment buried in the ground. Usually, PVC pipes are used to surround multiple groups of cables and then bury them in the ground, thereby saving ground space and increasing the beauty of the ground.

[0003] In the prior art, the use of PVC pipes to surround multiple groups of cables and then bury them in the ground is inconvenient for disassembly and maintenance on the one hand, and on the other hand, they are easily broken by external excavators and have poor protection. The protection device of the buried transmission line solves the above problems. SUMMARY OF THE INVENTION

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a protection device for buried transmission lines...
