Rapid grounding rod with plugging device, suitable for temporary opeartion

Abstract

Provided is a rapid grounding rod with a plugging device, suitable for temporary opeartion. A main objective is to solve problems that a grounding rod used in existing logging operation cannot easily be rapidly fixed and detached. The rapid grounding rod is characterized in that on a grounding rod main body, between the lower part of a threading groove and the upper part of an external thread segment, a plurality of embedded circular rings are fixed at equal interval, the longitudinal section of the bulge part of the embedded circular ring is in a trapezoid shape, and the plurality of embedded circular rings form a left straight-toothed rack and a right straight-toothed rack from top to bottom. The grounding rod also comprises a support sleeve with a support cylinder skirt base. The top end of the support sleeve is welded and fixed with two vertical ear plates. A pair of straight toothed spur gear plates are respectively fixed between the two vertical ear plates through gear plate bearings. The grounding rod main body is in the support sleeve. The straight teeth on the pair of straight toothed spur gear plates are respectively meshed with the left straight-toothed rack and the right straight-toothed rack which are formed by the plurality of embedded circular rings. The pair of straight toothed spur gear plates are respectively fixedly provided with symmetric insulation compression bars.

Description

technical field [0001] The invention relates to a grounding rod which is suitable for the drawworks of the well logging instrument in the field of oil field logging when implementing the logging operation. Background technique [0002] The grounding rod is a commonly used protection device in the operation of the power system. Its main function is to prevent lightning strikes and lead high-voltage electricity into the ground. Easy to pull out for long-term and stable protection. In well logging operations, the ground rod is also an indispensable device. According to CNPC's logging operation instructions and operating standard documents, the logging tool drawworks must use ground rods when performing logging operations, and shuttle buses or camping vehicles are used as supplementary vehicles for transporting logging instruments, auxiliary equipment and HSE equipment. It is a temporary rest place between wellhead work during the stay. No matter whether the power is connected...

AI Technical Summary

Problems solved by technology

This method of pulling out is a helpless move, which is laborious and affects timeliness. There have even been incidents where the grounding rod was nailed too deep and could not be pulled out. The logging tool winch was able to leave the well site by cutting the grounding wire and abandoning the grounding rod.

In a nutshell, the existing grounding rods for well logging have the following problems: (1) single heavy hammer nailing method, if the heavy hammer is lost during well logging construction, it will not be able to enter the ground, which directly affects the inability to perform well logging operations; ( 2) Restricted by the timeliness of logging operations, it is difficult to pull out in a short time, especially in the winter operation period; (3) The ground wire and ground rod are the simplest winding contact connection, which is not laborious and easy to oxidize. Rust increases resistance and reduces conductivity
