AI Technical Summary

Technical Problem

In the existing technology, high-voltage cable recovery in narrow tunnels is inefficient and labor-intensive, and the existing equipment cannot meet the cable bending radius requirements, resulting in insulation layer damage and operational difficulties, and unable to meet the construction period requirements.

Method used

The portable collection device adopts a tricycle structure, equipped with an adaptive cable guide device and a new energy battery. It realizes orderly winding of the cable through motor drive and control handle, ensuring that the cable bending radius meets the specifications and does not require an external power supply.

Benefits of technology

It improves the cable recovery efficiency, reduces labor intensity, ensures the safety and adaptability of the cable, adapts to the narrow tunnel environment, and realizes efficient and safe cable recovery.
