Electric grounding pile for electric power engineering

Abstract

The invention discloses an electric grounding pile for electric power engineering. The grounding pile comprises a grounding pile body, a cavity, a plug, a push rod, an accommodating groove, a rotatingshaft, a gear, a groove, a spring, a limiting plate, a rack plate and an elastic plate. The cavity is arranged in the grounding pile body, the top end of the grounding pile body is provided with theplug, and a wiring hole is formed in the plug. The push rod is arranged in the cavity, the accommodating groove is formed on the inner side wall of the cavity, and the rotating shaft is fixedly arranged in the accommodating groove and is rotatably connected with the gear. The rack plate is fixedly arranged on the push rod, a groove with an opening at the bottom end is formed at the top end of thecontaining groove, and the spring is fixedly connected to the side wall of the groove. The other end of the spring is fixedly connected with the limiting plate, the other side face of the limiting plate is closely connected with the side wall of the groove, and the bottom end of the limiting plate extends between every two adjacent meshing teeth and is hinged to the elastic plate. In general, theelectric grounding pile has the advantages of being firm in fixation, being not prone to being pulled out and being capable of reducing the maintenance cost.

Description

technical field [0001] The invention relates to a ground pile, in particular to an electric ground pile for electric engineering. Background technique [0002] Power transmission lines and related equipment are mostly located outdoors, and are prone to lightning strikes. Line trips caused by lightning strikes often occur. In order to prevent lightning strikes, it is necessary to install grounding devices for transmission lines to guide the current generated by lightning strikes to the ground to avoid The wires or power transmission equipment are damaged by the lightning voltage. The existing grounding piles are hammered into the ground by external forces, and are easily pulled out by external forces, which brings hidden dangers to the safe operation of the lines and high maintenance costs. [0003] Therefore, in order to solve the above problems, it is necessary to develop a power grounding pile for power engineering. Contents of the invention [0004] The object of the p...
