Description

Technical Field

[0001] The utility model relates to a grounding device, in particular to a compressor grounding component, belonging to the technical field of compressors. Background Art

[0002] The grounding wire is a wire directly connected to the earth, and can also be called a safety return line. When danger occurs, it transfers high voltage directly to the earth. It can be considered a lifeline. When the compressor is used as the heart of the refrigeration system, multiple sets of refrigeration equipment need to be installed in the factory that requires refrigeration to ensure the normal production needs. In order to ensure the safety of the refrigeration equipment and the internal compressor, a grounding wire is usually connected to reduce the risk of static electricity and electrical failure.

[0003] A Chinese patent publication (publication number: CN208986200U) discloses a compressor grounding assembly, which includes a grounding block, a grounding terminal, a thrust block and a locking screw; the grounding block is a grounding block on the compressor, the thrust block, the grounding terminal and the grounding block are arranged in sequence from top to bottom, the locking screw passes through the thrust block and the grounding terminal, and is threadedly connected to the grounding block, and the thrust block is used to fix the wiring terminal to prevent the wiring terminal from rotating;

[0004] Although the device can firmly fix the grounding wire, each grounding block can only be connected to one set of grounding terminals. When grounding equipment used by multiple compressors, multiple sets of grounding wires need to be installed to connect the grounding wires. This reduces the ability to manage multiple sets of grounding wires during subsequent inspections and maintenance, thereby increasing the labor intensity of maintenance. Utility Model Content

The outer wall of the stud 8 is inserted with an O-type grounding wire 10, and the top of the stud 8 is threadedly connected with a nut 9. By using the O-type grounding wire 10, it can be put on the stud 8 and fixed with the nut 9, and the O-type grounding wire can be crimped firmly.

[0026] In one embodiment, a conductive plate 3 is fixedly connected to the bottom end of the grounding metal rod 2. The conductive plate 3 can conduct a large amount of current transmitted from the grounding metal rod 2 to the ground through the conductive plate 3, thereby improving the conductivity. The conductive plate 3 is formed by welding four metal plates. The four metal plates can conduct current to the ground from multiple sides, so that the device has good conductivity.

[0027] In one embodiment, the conductive plate 3 and the grounding metal rod 2 are buried underground. The conductive plate 3 and the grounding metal rod 2 are buried underground, and the transmitted electricity can be sent to the earth to achieve the safety of the safety protection equipment and the operator. The grounding box 1 is placed on the ground. The grounding box 1 is placed on the ground and multiple sets of O-type grounding wires 10 can be installed to fix it.

[0028] In one embodiment, limiting grooves 11 are provided on the outer walls on both sides of the grounding box 1.
