Description
Technical Field
The invention belongs to the technical field of power cable construction equipment, and particularly relates to a full-automatic grounding device for cable repair.
Background
As known in the art, when a cable is broken due to theft or natural factors such as ice, snow, and wind, the broken cable needs to be repaired in time, and a ground wire needs to be connected to the broken cable (grounded) before the broken cable is connected according to the operating regulations of the national grid company. The method comprises the following steps: one end of the ground wire is electrically connected to the cable at a location corresponding to the broken cable jacket (i.e., the "outer insulation layer") after the broken cable jacket is punctured, and the other end of the ground wire is grounded.
The devices for temporary earthing of cables, such as CN103022751B (a earthing cable clamp), CN106848912A (high-voltage cable head earthing device) and CN109273875A (a conductive chuck of a cable terminal earthing protection wire), etc., are not known in the published chinese patent documents. The above-mentioned patent, which is not limited to the above-mentioned patent, does not have a function of piercing the outer surface of the cable with an insulating layer, and thus is not a tool for normal construction in power line construction work, but is not a tool for repairing a broken cable, and is not a tool for indicating the structure of the grounding device having a piercing function.
The combined puncture clamp recommended by CN100369326C, the puncture clamp provided by CN201025633Y and the insulating puncture clamp with electric protection function introduced by CN201616510U can puncture the outside of the cable, so that the combined puncture clamp is suitable for grounding when the broken cable is repaired.
The "cable puncturing device and puncturing tool for the device and equipotential connecting line thereof" disclosed in CN1021076606A overcomes the disadvantages of the aforementioned CN100369326C and the like and can embody the technical effects thereof described in paragraph 0016 of the specification, but still has the following disadvantages: firstly, because the pricking pin is forced to pierce the outer coating (see paragraph 0029 in the specification) by manual holding and pinching operation, the operation is relatively laborious, and particularly, the hardness of the outer coating of some cables is high, so that the effect that the pricking pin penetrates the outer coating and is in electrical contact with the conductor of the cable core is difficult to ensure; secondly, because the puncture is performed manually, namely by hand, the puncture speed is influenced; thirdly, after the puncture is finished and the cable puncture device is withdrawn from the cable, the puncture piece body is temporarily kept on the cable in an independent mode under the condition that the support or the care of the cable puncture device is lost until the cable connection work is finished, so that the puncture piece body has the risk of falling off, the grounding function cannot be realized, and the safety cannot be ensured. In view of this, there is a need for reasonable improvements, and the solutions described below have been made in this context.
