description | The invention belongs to the technical field of grounding resistance measurement, and discloses a tower grounding resistance measuring device which comprises a box body, a box cover, a sealing assembly and a pressing assembly, a contact ring is fixedly connected to an opening of the box body, and an extrusion plate is located below the contact ring and slidably arranged on the inner side wall of the box body. The sealing piece is arranged between the extrusion plate and the contact ring, the driving mechanism is movably arranged on the inner side wall of the box body and can make contact with the box cover, the driving mechanism is in transmission connection with the pressing piece, the pressing piece is connected to the extrusion plate, and when the box cover covers the opening of the box body, the driving mechanism drives the pressing piece to move upwards along the wall face of the box body; the pressing piece drives the extrusion plate to approach the sealing piece and extrude the sealing piece, so that t |
