Threaded high-voltage grounding wire operating rod extension device

technical field

The invention relates to the field of electric equipment, in particular to a threaded high-voltage grounding wire operating rod extension device.

Background technique

In the construction of high-voltage lines or substation maintenance, portable high-voltage grounding wires are commonly used to prevent electrostatic induction electric shocks near electrified bodies or to ensure safety when closing the switch by mistake. However, when the grounding wire is suspended on a line or equipment with a high height, due to the limited length of the operating rod, it is necessary to use an insulating step stool to increase the height, thereby reducing the safe distance between the human body and the live equipment, and there is also a risk of falling from the step stool. Dangerous, there are potential safety hazards.

At the same time, the inner cylinder and the outer cylinder stop relative rotation, and the outer cylinder moves to the upper part of the shell, and cooperates with the retaining ring to tighten the protective ring. ring. After use, turn the control lever, the inner cylinder is reset, the outer cylinder is away from the retaining ring card, and the high-voltage grounding wire operation lever is removed.

As an improvement: a protrusion is provided on the inner upper part of the outer cylinder, and a surrounding ring is provided on the lower part of the inner cylinder near the second opening. After the inner cylinder rotates in the outer cylinder, the upper and lower parts of the handle are constrained and no deviation occurs.

As an improvement: the outer cylinder is provided with a bottom surface, and a side of the bottom surface close to the first opening is provided with a low platform. When the handle is installed, it contacts with the bottom surface to prevent the high-voltage grounding wire operating rod from rotating when the inner cylinder rotates.

As an improvement: the limiting device includes an arc-shaped hole, the arc-shaped hole is arranged on the bottom surface, a connecting rod is provided between the inner cylinder and the control rod, and the connecting rod passes through the arc-shaped hole. The arc hole limits the rotation angle between the shell and the outer cylinder.

As an improvement: the connecting rod is L-shaped, and the control rod is located in the center of the housing.

As an improvement: the control rod and the casing are provided with a limit plate. Keep the lever in the center of the housing.

As an improvement: the lower part of the upper end of the shell is provided with a handle and a retaining ring. Allow multiple devices to be connected in series

As an improvement: the control lever is provided with a handle.

As an improvement: the control rod is detachably connected with the handle.

As an improvement: the shape of the grommet is C-shaped or U-shaped.

Due to the adoption of the above-mentioned technical scheme, the present invention enables workers to hang grounding wires to higher-height lines or equipment while occupying the ground, while being safe and reliable, saving time and effort, being convenient to carry, and improving work efficiency.

The present invention will be further described below in conjunction with drawings and embodiments.
