▎ 摘　　要

NOVELTY - The device has a main body provided with an adjacent composite graphene rod. The adjacent composite graphene rod is fixedly connected to a connecting structure. The connecting structure is provided with an upper combined body, a lower combined body and a connecting sleeve (2). The composite grounding graphene is sequentially provided with an upper combination body (13), a rod body (11) and a lower combination body from the upper part to the lower part. The upper combining body and the lower combining body is inserted in the horizontal direction for forming a cylinder coaxial with the rod bodyafter inserting, where the outer diameter of the cylinder body is less than that of the rod. USE - Graphene composite grounding device. ADVANTAGE - The grounding device is provided with simple and easy operation of the connection structure so that the graphene the composite grounding rod saves time and labor, at the same time, the connection effect is good, and it is not easy to loose. The grounding rod is ensured not to be influenced by the bad environment of the underground. The fastening effect of the connecting sleeve is enhanced by using steel wire of fastening at the periphery of connecting sleeve.
