[0002] A distribution grounding pile is a grounding device used in a power distribution system. It is mainly used to ground the leakage circuit of the current to ensure the safe operation of electrical equipment. The distribution grounding pile is usually made of metal material, one end of which is connected to the grounding line of the electrical equipment and the other end is buried underground. By grounding the leakage circuit of the current, the distribution grounding pile can effectively conduct the current into the underground, avoiding the impact of leakage of electrical equipment on personal safety and equipment damage.

[0003] In the prior art, during the installation of the power distribution grounding pile, the grounding pile needs to be extended to a specified depth underground to ensure the stability of the grounding pile during use.

At the same time, the side walls of the pile are relatively smooth and have poor anti-pull-out effect after being extended underground. It is easy to be affected by external vibrations or other influences and move upward from the ground, which will affect the installation quality of the grounding pile. Utility Model Content
