Abstract

The invention provides an external grounding device and belongs to the technical field of electric power construction tools. The external grounding device comprises a grounding panel, a grounding mechanism, a driving mechanism and a lubrication mechanism, wherein the grounding panel is provided with a grounding pole, the grounding mechanism is arranged on the grounding panel, the driving mechanismis used for driving the grounding mechanism to operate and enter into the ground, and the lubrication mechanism is used for injecting lubricating fluid during the drilling process of the grounding mechanism. According to the external grounding device provided by the invention, the driving mechanism is adopted to drive the grounding mechanism to enter the ground, and the manual drilling of a grounding rod is not required; the lubrication mechanism is adopted, during the drilling of the grounding rod, the grounding rod can be lubricated, so that the grounding rod can enter into the ground conveniently and quickly. The grounding device is mainly to prevent thunderstorm and lightning from damaging the shell of a working tool and hurting an operator. When it is rains with thunder and lightningaccompanied, the grounding device can reliably guide lightning to the ground so as to ensure the safe operation of the worker and equipment and protect the safe operation of the worker and the equipment.

Description

technical field [0001] The invention belongs to the technical field of electric construction machines, and more specifically relates to an external grounding device. Background technique [0002] With the need for maintenance and maintenance of large and medium-sized power equipment and lines such as power grids, power equipment, distribution lines, and transmission lines, the working area of ​​many equipment is far away from the main grounding terminal under the power structure, making maintenance personnel Personal safety cannot be guaranteed. [0003] In the existing substation grounding facilities: 1) The main grounding body is mainly the grounding system of the equipment area in the power grid. The connection structure is the ring network grounding of the main equipment. If the equipment needs to choose a grounding point, it is easy to The grounding bolt of the equipment shell is tightened and the wire is slipped or broken, and the grounding surface is unreliable. 2) ...
