Grounding device

The invention belongs to the technical field of power construction, and discloses a grounding device which comprises a wiring assembly and a grounding assembly; the grounding assembly comprises a grounding body and a connecting assembly; the grounding body is connected with a grounding grid; the connecting assembly is rotationally arranged on the grounding body; and a connecting part is arranged on the wiring assembly. When to-be-grounded equipment is powered off, the connecting assembly is driven to rotate relative to the grounding body to make the connecting assembly connected with the connecting part, so that the wiring assembly is fixed to the grounding assembly, and residual charges on the to-be-grounded equipment smoothly flow to the grounding grid through a grounding wire and the grounding device; after the maintenance is completed, the connecting assembly is rotated reversely, so that the connecting assembly is separated from the connecting part, then the connection between the wiring assembly and the
