Description

A ground wire retractable device

technical field

The utility model relates to the technical field of electric wire retraction, in particular to a grounding wire retraction device.

Background technique

Hanging the ground wire is the most important part of the power maintenance work. During the power maintenance, after the experience proves that the equipment is clearly without power, the ground wire should be installed immediately. The length of the grounding wire is also different in different environments. In the maintenance of 10 kV line, a grounding wire of about 12 meters is often used.

The grounding wire is frequently used in daily maintenance work. If the grounding wire is wound into a circle and then strung together, it is very inconvenient to carry and organize the grounding wire, and the grounding wire is prone to knotting when the grounding wire is opened. Or it is easy to be hooked by other tools, etc. It takes a lot of time to deal with it and reduces work efficiency. Moreover, the length of the grounding wire is relatively long, and problems such as messy storage will occur when the grounding coils are stored in a string.

If the grounding wire is wound on the spool like a cable, it is not easy to be knotted when the grounding wire is retracted and unwound, and it is not easy to cause the grounding wire to be hooked by other tools, and it also avoids when the grounding coil is stored in a string. messy storage and other issues. But, when paying off with the bobbin, need to rotate the bobbin along with the grounding wire unwinding, make the grounding wire constantly pay out. And, when taking up the wire with the bobbin, it is also necessary to reversely rotate the bobbin along with the winding of the grounding wire, so that the grounding wire is wound on the bobbin. Like this, use the spool to retract the grounding wire, the work efficiency is low, time-consuming and labor-intensive.

Therefore, need a kind of grounding wire retractable device that can store neatly, carry conveniently, and retractable wire conveniently in electric power maintenance work.
