A portable ground rod installation power mechanism

Abstract

The invention discloses a portable ground rod installation power mechanism, which comprises: a steel cylinder with an opening at the lower end, a spring at the top of the inner cavity of the steel cylinder, an iron core capable of moving up and down in the cavity of the steel cylinder with a width greater than the opening at the lower end of the steel cylinder, An iron hammer fixedly connected to the bottom end of the iron core, the width of the hammer is smaller than the opening at the lower end of the steel cylinder; wherein, a pair of guide rail pairs are provided on the left and right sides of the inner wall of the steel cylinder, and the inner side of the guide rail pair is parallel to the axial direction. The outer layer of the ball and the guide rail pair is wound with a coil along the axial direction; the inner side of the guide rail pair on one side, at the gap between the iron core and the inner wall of the steel cylinder, starting from the bottom of the inner cavity, there are Hall sensors at intervals. The device can give the hammer enough impact force within a limited height range, so as to realize the mechanical and automatic installation of the grounding rod. Good portability, easy to use in various construction environments.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance equipment, in particular to a portable ground rod installation power mechanical device. Background technique [0002] The grounding device occupies an extremely important position in the grounding protection of the power equipment line of the distribution network. When the power equipment is subjected to induced overvoltage, short-circuit overvoltage, and induced lightning strike, the grounding current generated instantaneously is very large, and the grounding electrode can quickly spread the grounding current. into the ground, avoiding the breakdown damage of power equipment and maintaining the normal operation of power line equipment. Generally, the grounding resistance of power line equipment is less than 10 ohms. The smaller the grounding resistance, the stricter the requirements for the material of the grounding electrode and the quality of construction and installation....

AI Technical Summary

Problems solved by technology

When the ground electrode is driven into the ground to a depth of less than 3 meters, manual installation is generally used. This method cannot ensure that the ground rod is vertically pressed into the ground, and because the ground rod will swing when held by hand, there are certain slits around the ground rod. The reason for the increase in the resistance value is often a problem here. It is necessary to repeatedly beat the surrounding soil or fill the resistance reducing agent several times to reduce the resistance value, resulting in slow installation speed and low efficiency.

[0003] In addition, when the grounding rod needs to be driven into the ground to a depth greater than 3 meters, especially when the installation depth is required to be 6-10 meters, the construction workers are very laborious and cannot drive the grounding rod into the ground.

In this case, the construction unit must first use the excavator to dig out the required vertical deep pit with the help of large-scale excavation equipment, then put the grounding electrode into the excavated deep pit, and use soil backfill to compact the excavated area. This construction method is very It is not economical, plus large machinery generally has a large power, large volume, and is relatively heavy. It requires trained and qualified professional and skilled workers to operate and use it. The cost of running such equipment is also very high.

On the other hand, the roads in many construction sites are narrow, and it is difficult for excavation machinery to enter and cannot be used for construction. Even in places with small working spaces, remote mountainous areas and the wild, large machinery and equipment cannot be used for construction.

[0004] At the present stage, there is no mature mechanical equipment that is convenient to operate, safe and reliable in the installation and use of grounding rods, which can directly drive the grounding rods into the ground
