Embodiment 1

[0019] Embodiment 1, the grounding wire anti-off protection device, such as figure 1 As shown, it includes the terminal clamp 1 connected to the grounding wire 2. The terminal clamp 1 is made of high-quality aluminum alloy die-casting. The grounding wire is fixedly connected to the terminal clamp 1 through the bolt group 12, and the grounding is realized by connecting the terminal clamp 1 and the wire. Line 2 is connected to the wire.

[0020] The connecting clip 1 includes a left wire clip 3 and a right wire clip 4 which are hingedly connected, and a torsion spring 5 is arranged at the hinge of the left wire clip 3 and the right wire clip 4, and the two ends of the torsion spring 5 are connected to the left wire respectively. The inner side of clip 3 and the inner side of right wire clip 4, under the effect of torsion spring 5, left wire clip 3 and right wire clip 4 are not under the effect of external force and are in closed state.

[0021] Two second hinged plates 4-2 are ...

Embodiment 2

[0027]Embodiment 2, the grounding wire anti-off protection device, the left wire clamp 3 is provided with a mounting hole 8 opposite to the right wire clamp 4, and the right wire clamp 4 is provided with a movable hole 9 corresponding to the mounting hole 8, and the support Rod 10 is hinged in mounting hole 8 and passes movable hole 9, and one end of support rod 10 passing movable hole 9 cooperates with described stop surface 6-2, and the setting of mounting hole 8 and movable hole 9 has both alleviated the whole The weight of the device can limit the range of motion of the support rod 10 and fully ensure the convenience of the support rod 10 abutting against the stop surface 6-2.

[0028] Other structures of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0029] Embodiment 3, the protection device for preventing the ground wire from falling off, the support rod 10 is hinged on the upper side of the torsion spring 5, and a tension spring 11 is arranged between the upper end surface of the support rod 10 and the upper side wall of the mounting hole 8, and the tension spring 11 is crimped on the hinged end of the support rod 10, so that the other end of the support rod 10 can always keep the upward tilting trend, ensuring that the support rod 10 is more stable and reliable when supporting the stop surface 6-2, and will not accidentally loosen. take off.

[0030] The overhauler can also lower the clamp 1 through the traction rope 7. Under the action of the tension spring 11, the support rod 10 has a tendency to tilt upwards, and the end of the support rod 10 can be stably attached to the stop surface 6-2. Support, as long as the traction rope 7 is not shaken vigorously, the support rod 10 will not be separated from the stop surface...

Abstract

The invention discloses a ground wire anti-fall protection device which solves the technical problem that a conventional portable short-circuit ground wire is inconvenient to hang and unlock. The ground wire anti-fall protection device includes a wire clip connected to a ground wire. The wire clip includes a left wire clip and a right wire clip that are hinged to each other. A torsion spring is disposed at the hinge of the left wire clip and the right wire clip. The two tail ends of the torsion spring are abutted against the inner side of the left wire clip and the inner side of the right wireclip. The right wire clip is hinged to a locking lever at the outer end surface of the lower side of the torsion spring. The locking lever is connected with a traction rope. The end portion of the locking lever away from the hinged end is connected with a right wire clip stopper. A passage groove is disposed on the locking lever. A stop surface is disposed in the passage groove. The left wire clip is hinged to a support rod in clearance fit with the stop surface. The ground wire anti-fall protection device can remotely control the opening and closing of the wire clip through the traction rope, thereby conveniently connecting or disconnecting a portable ground wire to or from a high-voltage wire.

Description

technical field [0001] The invention relates to the technical field of grounding wire connection, in particular to a grounding wire detachment prevention protection device used in line maintenance. Background technique [0002] The short-circuit grounding wire is a safety short-circuit device to be connected in the power industry before maintenance after the equipment or line is powered off. It is used to prevent sudden calls and prevent damage to operators or equipment. [0003] The existing portable short-circuit grounding wire is composed of an insulating support rod and a wire clip. The wire clip is made of high-quality aluminum alloy die-casting with high strength, and the surface of the wire clip is not suitable for oxidation after surface treatment. The operating rod is refined into a colored tube with imported epoxy resin, which has good insulation performance, high strength, light weight, bright color and smooth appearance. However, it is very inconvenient to use t...
