AI Technical Summary

Benefits of technology

This technology uses an underground system where electric wires are placed inside pipes that protect them from being damaged due to environmental factors such as water intrusion. When there're no signs left by pets while digging up for new electrical lines, this design prevents any harm caused by breaking out too much wire. Its technical effect includes improved safety measures against outside hazards, reduced costs over longer periods, increased efficiency compared to traditional methods like covered tunnels, and ability to install hidden cables alongside existing ones without causing problems.

Problems solved by technology

This patented technical problem addressed in this patents relates to prevention of damage caused from cutting through buried cords used for communication purposes such as telecommunications networks when they were laid down beforehand without identifying themselves with specific markers attached thereto. Additionally, current methods require manual detection of cables after excavated operations, making it difficult to fully cover up any potential hazards while ensuring proper placement.

Embodiment Construction

[0014] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a physical anti-breakage device for directly buried cables includes several resistance devices 1 buried above the cables at intervals, and a strong connection device is connected between two adjacent resistance devices 1, and the strong connection The device includes connecting ropes 2 horizontally spaced and connected between two resistance devices.

[0016] The resistance device 1 is a cube-shaped resistance block.

[0017] The connecting rope 2 is an aramid yarn braided rope.

[0018] A moisture-proof and corrosion-proof protective sheath 3 is coated on the outside of each connecting rope 2 .

[0019] The diameter of the connecting rope 2 is 50 mm.

[0020] The length of the resistance device 1 is 600 mm, the width is

Abstract

A physical external-damage prevention apparatus for a directly-buried cable comprises a plurality of resistance devices buried over a cable at intervals, wherein a strong connecting device is connected between the two adjacent resistance devices, and the strong connecting device comprises a connecting cord horizontally connected between the two resistance devices at intervals. According to the physical external-damage prevention apparatus for the directly-buried cable provided by the present invention, by adopting the above scheme, the plurality of resistance devices are laid over the cable when the cable is buried, so that once excavation is performed when an identifier at the cable, the cable will not be damaged, thereby avoiding occurrence of accidents, such as cable breakage and short lines. The apparatus meets external-damage prevention strength requirements, and is low in cost and long in service life, and can achieve relatively high economical benefits. The installing construction is simple, installation without power interruption can be implemented, and the apparatus will not cause disturbance and impact on other devices in the installation process. The installation of the apparatus and the direct burying of the cable can be synchronized, and after the construction is completed, the original appearance of the earth surface can be restored, without affecting the city appearance.
