Multi-umbrella vertical grounding electrode device

A multi-umbrella vertical grounding electrode device disclosed by the present invention comprises a tubular vertical grounding electrode main body, a plurality of V-shaped unfolding racks are arranged on the outer wall of the vertical grounding electrode main body at intervals up and down, and each V-shaped unfolding rack comprises sub grounding electrode tubes symmetrically arranged on the two sides of the vertical grounding electrode main body. The lower ends of the sub-grounding electrode tubes are hinged to the vertical grounding electrode main body, and the upper ends of the sub-grounding electrode tubes are barb structures extending outwards; the sub-grounding electrode tubes are unfolded outwards, inserted into soil and unfolded in a V shape, so that the contact area between the grounding electrode and the ground can be increased, the conductivity is increased, the grounding performance requirement of an electric power system is met, construction is easy and convenient, and time and labor are saved; th
