Electric grounding post for electric power engineering

Abstract

The invention discloses an electric power grounding post for electric power engineering. The electric power grounding post comprises a grounding post, wherein a positioning mounting disc is welded atthe top of the grounding post, the top of the positioning mounting disc is in threaded connection with a mounting sleeve, a first grounding cone is welded at the bottom of the grounding post, the interior of the grounding post is hollow and is fixedly provided with an internal threaded limiting disc, a positioning lifting sleeve with external threads is movably inserted into the grounding post, the interior of the positioning lifting sleeve is of a hollow structure, the positioning lifting sleeve spirally penetrates through a center through hole of the internal threaded limiting disc, the bottom of the positioning lifting sleeve movably penetrates through the first grounding cone to be connected with a second grounding cone, the interior of the second grounding cone is of a cavity structure, and the interior of the positioning lifting sleeve is communicated with the cavity of the second grounding cone. According to the invention, the structure of the existing grounding post is improved, so that the grounding post can be inserted into the ground firmly, early-stage and late-stage good use is facilitated, manpower is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of grounding posts, in particular to an electric grounding post for electric power engineering. Background technique [0002] Power equipment is vulnerable to lightning strikes during long-term use, and line trips due to lightning strikes often occur. In order to prevent lightning strikes, it is necessary to install lightning protection devices for electrical equipment to guide the current generated by lightning strikes to the ground to prevent lines and electrical equipment from being damaged by lightning voltage. The grounding device needs to be reliably grounded, and a metal grounding post is usually used. The grounding post is hammered into the ground by external force. However, since the grounding post is directly driven into the ground, the protection effect on the grounding post is not good. After a long time, it is easy to loosen and cause loss. At the same time, it will affect the installation of o...

Problems solved by technology

The grounding post is hammered into the ground by external force. However, since the grounding post is directly driven into the ground, the protection effect on the grounding post is not good. After a long time, it is easy to loosen and cause loss. At the same time, it will affect the installation of other components, and it will cost a lot of money. manpower and material resources to re-install the grounding post
