Description

Technical Field

[0001] The utility model relates to the technical field of grounding component devices, in particular to a grounding component used for a power cabinet. Background Art

[0002] A grounding device is a general term for a grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment. A grounding device is also called an integrated grounding device, which is a device that forms an electrical connection between electrical equipment or other objects and the ground. It is used to connect the electrical system to the earth. A metal object that is in direct contact with the earth to achieve electrical connection is a grounding electrode. It can be an artificial grounding electrode or a natural grounding electrode. This grounding electrode can be given a certain electrical function, such as system grounding, protective grounding or signal grounding. Through it, the equipotential bonding wires in the electrical device are interconnected, thereby achieving a total equipotential bonding between large conductive parts in a building. The connecting wire between the grounding electrode and the grounding busbar is called a grounding electrode lead.

[0003] For example, a grounding component with the announcement number CN113224556A includes a vertical grounding electrode, a horizontal grounding strip and a connecting piece. There are multiple vertical grounding electrodes, and each vertical grounding electrode includes a first braided layer, a first support frame, a first resistance reduction filler, a hard shell and an impact head. The first braided layer is cylindrical and includes an accommodating cavity. The first support frame is arranged in the accommodating cavity. The first resistance reduction filler is arranged in the accommodating cavity. The hard shell can be covered on the first braided layer. The impact head is fixedly arranged at the lower end of the first braided layer and can be detachably connected to the hard shell. There are multiple horizontal grounding strips, and the connecting piece is used to connect each vertical grounding electrode to an adjacent horizontal grounding strip.

[0004] The above device can ensure that when graphite is used as the conductive material, the work difficulty is reduced, the process steps are reduced, and thus the work efficiency is improved. However, the drill bit of the above device can only be inserted on a surface with relatively soft soil. If a harder geology is encountered, the drill bit set at the front end will not be effective, and the support frame placed inside the device has a relatively loose structure and is prone to falling off.

[0007] Preferably, a connecting device is provided at the lower end of the rotating cover, and an electrical connecting component is placed inside the connecting device.

[0008] Preferably, a graphite filling column is arranged in the center of the hard shell, and the graphite filling column is arranged in a cylindrical shape and is placed in the middle of the hard shell in a full state.

[0009] Preferably, a fixed column is arranged in the center of the graphite filling column, and the lower end of the fixed column is connected to the isolation end arranged on the upper end of the bottom spiral drill bit, and the upper end of the fixed column is connected to the partition arranged on the lower side of the connecting device.

[0010] Preferably, the fixed column is composed of a plurality of unit sections, and a ring side column is arranged beside the unit section, and a connecting rod is arranged between the ring side column and the fixed column.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with other grounding components for power cabinets, the present device can also be effective on hard surfaces through the setting of the front spiral front drill, and the drilling rig can be connected through the upper access component to allow the front end of the device to have a ground drilling effect, and the design of the spiral pattern reduces friction for ground drilling and increases the surface adaptability of the present device. In addition, the device changes the shape of the support frame of each section, and the central and peripheral settings provide the support frame with basic support force to stabilize the graphite material set inside, and the stability is relatively more prominent, avoiding the phenomenon of structural collapse.
