Problems solved by technology

[0003] In the actual installation work, the operator stands on the pole, and the operating arm forms an angle with the wire, which causes the grounding wire clip and the wire to be not fastened firmly, and the contact is not comprehensive, which affects the grounding effect, and because the grounding wire clamp is heavy, the operation The personnel need to use both hands to lift the grounding wire assembly for installation, which usually takes 20 to 30 minutes. In addition, the operator needs to wear insulating gloves to work, which is inconvenient to operate and consumes time and physical strength. For grounding installation, it is necessary to replace the grounding clamp with the appropriate size

Embodiment 1

[0044] refer to Figure 1-5 , is the first embodiment of the present invention, which provides a grounding clamp for a ten thousand volt distribution line, which can adjust the inclination angle between the operating rod 300 and the wire 400, so that the main body 200 is always kept vertical state, clamp the wire 400 vertically.

[0045] Specifically, the ground clamp of the ten thousand volt power distribution line includes a connecting unit 100, a main body 200 and an operating rod 300, and the connecting unit 100 connects the main body 200 and the operating rod 300, wherein the connecting unit 100 includes a first connecting body 101 and the second connecting body 102 , the first connecting body 101 and the second connecting body 102 are rotatably connected by a rotating shaft or a bearing, and the first connecting body 101 is connected to the operating rod 300 , and the second connecting body 102 is connected to the main body 200 .

[0046]Based on the above, the second c...

Embodiment 2

[0056] refer to Figure 6-9 , is the second embodiment of the present invention, different from the previous embodiment, this embodiment directly pulls the flexible member 301 through the fastening rod 303 to make the telescopic rod 204 shrink, the operation is quick, and the physical strength of the staff is saved. The stable state in nature automatically adjusts the clamping angle and contact point to achieve a more fitting and stable effect.

[0057] Specifically, the operating rod 300 may include a fixed rod 302 and a fastening rod 303. The fixed rod 302 is connected to the first connecting body 101 through a buckle or screw thread. Extend through the fixed rod 302 to the inside of the fixed rod 302. Preferably, the outer diameter of the exposed part M of the fastening rod 303 needs to be larger than the outer diameter of the built-in part N. The built-in part N is a sliding connection between the polished rod and the fixed rod 302. The built-in part N The upper end face ...

Embodiment 3

[0061] refer to Figure 10 , is the third embodiment of the present invention, different from the previous embodiment, this embodiment can realize the clamping of the wire when the operating rod 300 is in the state of free rotation, and the state of the operating rod 300 will not affect the installation. Clamp effect and stability.

[0062] Specifically, the telescopic end of the telescopic rod 204 can also be connected to the second connecting body 102 through the flexible piece 301. When the operating rod 300 connected to the connecting unit 100 is rotated, the flexible piece 301 is pulled to wrap around the second connecting body 102. The telescopic rod 204 is provided with a through hole 304 for the flexible member 301 to pass through, and the second connecting body 102 and the flexible member 301 are connected by a mutually detachable buckle 301c, and the buckle 301c is arranged on the upper part of the second connecting body 102, In order to prevent the flexible member ...

Abstract

The invention discloses a ground clamp for a ten thousand volt power distribution line, which comprises a connecting unit, a main body and an operating rod, the connecting unit connects the main body and the operating rod, and the connecting unit includes a first connecting body and a second connecting body body, the two are connected in rotation, the main body includes a grounding part, a fixed part, a movable part and a telescopic rod connecting the fixed part and the movable part, the fixed part and the movable part both include a wire clamp, and the wire clamp is connected to the The grounding part is connected, wherein, the connecting rod of the fixed part is fixedly connected with the fixed end of the telescopic rod and the grounding part, and the telescopic connection between the connecting rod of the movable part and the telescopic rod Both ends are flexibly connected to the grounding part, and the operating rod is connected to the telescopic end of the telescopic rod through a flexible piece. The invention achieves the effect of vertically clamping the wire by adjusting the clamping inclination angle between the operating rod and the wire, and the bonding with the wire is more stable, the operation is quick and labor-saving, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance safety protection tools, in particular to a grounding clamp for a ten-kilovolt power distribution line. Background technique [0002] The grounding wire is a kind of safety tool for temporarily short-circuiting the grounding of the equipment that has been powered off. Its function is to prevent the sudden call of the equipment and the induced voltage generated by the adjacent high-voltage live equipment from harming the human body when the high-voltage equipment is powered off for maintenance or other work. Discharge residual charge from de-energized equipment. [0003] In the actual installation work, the operator stands on the pole, and the operating arm forms an angle with the wire, which causes the grounding wire clip and the wire to be not fastened firmly, and the contact is not comprehensive, which affects the grounding effect, and because the grounding wire clamp is heavy...
