Description

Technical Field:

[0001] The utility model relates to the technical field of grounding, in particular to a tower grounding device. Background Art:

[0002] A grounding device generally refers to the grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment, which is a device that forms an electrical connection between an electrical equipment or other object and the ground.

[0003] Currently, most of the existing grounding devices for power towers directly insert the grounding wire into the ground for use. The grounding wire uses copper-plated grounding flat steel. In relatively moist soil, due to poor protection measures, the grounding wire is easily affected by the service life under long-term soil corrosion. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a tower grounding device to solve the problems raised in the above background art.

[0005] The utility model is implemented by the following technical solutions:

[0006] A tower grounding device includes a base seat fixed on the ground. A protective cap is fixed on the base seat. A tower is vertically installed on the protective cap. One side of the bottom of the tower is fixed with a connecting piece. The connecting piece is fixedly connected with one end of a copper-plated grounding flat steel through a bolt. The surfaces of the base seat and the protective cap are continuously provided with wiring grooves in a "stepped" shape. A lower wiring groove plate and an upper wiring groove plate are fixed in the wiring grooves. The lower wiring groove plate and the upper wiring groove plate are buckled with each other to clamp the copper-plated grounding flat steel between them. One end of the copper-plated grounding flat steel placed underground is welded to one end of a graphite grounding wire. A heat shrinkable tube is also sleeved outside the connection of the lower wiring groove plate, the upper wiring groove plate, the copper-plated grounding flat steel and the graphite grounding wire. After the heat shrinkable tube is heated, it shrinks to seal and wrap the outside of the connection of the lower wiring groove plate, the upper wiring groove plate, the copper-plated grounding flat steel and the graphite grounding wire.

[0007] Preferably, the surface of the copper-plated grounding flat steel is plated with an oxidation-resistant coating.

[0008] Preferably, the lower wiring groove plate has a "U" shape structure, the upper wiring groove plate has an "inverted U" shape structure, and the upper wiring groove plate is located above the lower wiring groove plate.

[0009] The advantages of the utility model: By adding protection measures outside or on the surface of the grounding wire, the grounding device on the ground is ensured not to be scratched and damaged, and at the same time, the grounding wire underground is prevented from being corroded, improving the service life of the grounding wire.
