[0018] 1. When the whole device needs to be installed, the box needs to be kept stationary so that when the twist valve is twisted, the grounding pile and the grounding column can only receive vertical force and extend into the ground, and the gripping teeth on the gripping floor will tightly bite the ground to prevent the box from rotating freely. The grounding grip of the electrical equipment in the thermal power plant is stronger.

[0019] 2. When the grounding device needs to be installed, step on the floor with both feet and grip it tightly. At this time, the gripping teeth grip the ground tightly. At this time, manually rotate the twist valve in the forward and reverse directions, thereby driving the screw rod to rotate in the forward and reverse directions, and then driving the circular plate to adjust the height through the threaded cylinder, thereby driving the four rectangular plates to adjust the height. When the four rectangular plates move downward, in this process, four grounding piles and one grounding column are driven deep into the ground to achieve grounding. The grounding device has a fast installation speed and a simple installation method. It is more convenient and quicker to use in the grounding of electrical equipment in thermal power plants.
