Description

Portable Grounding Device

technical field

The invention relates to a portable grounding device, which belongs to the technical field of safe electricity utilization.

Background technique

The function of the grounding device is mainly to prevent people from electric shock, ensure the normal operation of the power system, protect lines and equipment from damage, prevent electrical fires, prevent lightning strikes, and prevent electrostatic damage. The grounding device of the power device is composed of a grounding electrode and a grounding wire. The grounding electrode is a metal conductor buried in the soil, and the grounding wire is a metal conductive wire. The grounding device should be applied to different electrical systems or electrical installations. The grounding wire needs to be connected to the electrical device that needs to be grounded. It is often necessary to weld the grounding wire to the electrical device. However, at the construction site, it is often difficult for the power supply and welding equipment to reach the welding position. The grounding wire in the grounding device is placed outdoors for a long time and is easily corroded.

Contents of the invention

The technical problem to be solved by the present invention is to provide a portable grounding device, which can prolong the service life of the grounding device and connect the grounding device with an electrical device.

The portable grounding device of the present invention includes a grounding body and a grounding wire. The grounding body is fixed at the lower end of the grounding wire, and a connecting piece is arranged on the upper end of the grounding wire. The connecting piece includes a fastening bolt, a jacking bolt, and a clamping body. The body is U-shaped, two fastening bolts are arranged on one side of the U-shaped clamping body, and the jacking bolts are arranged at the lower end of the U-shaped clamping body.

The upper end of the connecting line is provided with a connecting piece, which includes a fastening bolt, a jacking bolt, and a clamping body. The clamping body is U-shaped, and two fastening bolts are arranged on one side of the U-shaped clamping body. Bolts are arranged at the lower end of the U-shaped clamping body. The connection between the grounding device and different electrical devices is greatly facilitated, and the grounding efficiency is improved.

The grounding wire is composed of a metal wire, a corrosion-resistant layer, and a rubber layer from the inside to the outside. The corrosion-resistant layer is made of graphite powder. The graphite powder outside the metal wire can protect the metal wire from corrosion and improve the durability of the grounding wire service life.

The grounding body is a metal rod, and the lower end of the metal rod is pointed, which is convenient for the grounding body to be inserted into the ground.

The upper end of the grounding body is provided with two hooks, which are convenient for winding the grounding wire, so that the grounding wire is not loose, neat and beautiful during transportation and storage.

The inner surface of the clamping body on the side where the fastening bolt is not provided has anti-slip serrations, which increases the reliability of the connection between the connecting piece and the electrical device that needs to be grounded.

work process:

Remove the grounding wire wound on the hook, adjust the fastening bolts and jacking bolts of the connecting piece on the upper end of the grounding wire, clamp the base or shell of the electrical device that needs to be grounded, and insert the grounding body into the to the ground.

Compared with prior art, the beneficial effect that the present invention has is:

1. The upper end of the connecting line is provided with a connecting piece, which includes a fastening bolt, a jacking bolt, and a clamping body. The clamping body is U-shaped, and two fastening bolts are arranged on one side of the U-shaped clamping body. The jacking bolts are arranged at the lower end of the U-shaped clamping body, which greatly facilitates the connection of the grounding device with different electrical devices and improves the grounding efficiency.

2. The grounding wire is composed of a metal wire, a corrosion-resistant layer and a rubber layer from the inside to the outside. The corrosion-resistant layer is made of graphite powder. service life.

3. The lower end of the grounding body is pointed, which is convenient for the grounding body to be inserted into the ground.

4. There are two hooks on the upper end of the grounding body, which is convenient for winding the grounding wire, so that the grounding wire will not be loose, neat and beautiful during transportation and storage.

5. The inner surface of the clamping body without fastening bolts has anti-skid serrations, which increases the reliability of the connection between the connector and the electrical device that needs to be grounded.
