[0030] See Figure 1 and Figure 2 This utility model discloses a mobile magnetic grounding device 1. The mobile magnetic grounding device 1 includes a first conductor 203, a grounding stake 204, a second conductor 101, a magnetic component 103, a wiring terminal 106, and a cover plate 104.

[0031] The second conductor 101 is a rectangular box-shaped grounding shell made of galvanized steel, with a rectangular receiving groove on the top of the grounding shell. Bolt holes are provided at each of the four corners of the top of the grounding shell.

[0032] The magnetic component 103 is a magnetic block made of a rectangular magnetic material. The magnetic block is adapted to the shape of the rectangular receiving groove on the top of the second conductor 101, for example, a slightly smaller rectangular block, so that the magnetic block can be embedded in the rectangular receiving groove.

[0033] The cover plate 104 can be made of galvanized steel. Each of the four corners of the cover plate 104 has a bolt hole, and two terminals 106 are provided at both ends of the cover plate 104.

[0034] After the magnetic block is embedded in the cuboid receiving groove, the cover plate 104 is placed on top of the cuboid receiving groove. The four bolt pre-drilled holes correspond one-to-one with the four bolt holes. The bolt 105 is a cylindrical threaded fastener made of galvanized steel. The bolt 105 passes through the bolt pre-drilled holes and connects with the bolt holes to fix the cover plate 104 on the grounding shell.

[0035] The grounding wire 202 of this utility model is a PE grounding wire.

[0036] The copper or brass terminal block 106 is a connector that connects the lug 107 to the cover plate 104. One end of the lug 107 is connected to the terminal block 106 on the cover plate 104, and the other end of the lug 107 is connected to the grounding wire 202 of the electrical equipment. The other end of the grounding wire 202 is electrically connected to the electrical equipment 201. It should be noted that in some embodiments, the lug 107 and the grounding wire 202 may also be part of the movable magnetic grounding device 1.

[0037] The first conductor 203 is a flat iron, which is welded to a grounding stake 204, which is buried in the ground 205. The upper surface of the flat iron has a certain area and can be rectangular or other planar structures. The upper surface of the flat iron is a ferromagnetic bearing surface. The first conductor 203 is arranged in at least one mechanical equipment operating area of ​​the construction site for grounding of electrical equipment in that area. In some embodiments, the first conductor 203 is also welded with branch sections that can extend to other electrical equipment. Each branch section can extend to any location of electrical equipment that needs to be grounded, and all branch sections are electrically connected to the grounding stake 204.

[0038] When any electrical device 201 needs to be grounded, the second conductor 101 is placed at a suitable position on the upper surface of the first conductor 203. Under the action of the magnetic component 103, the second conductor 101 is magnetically attracted to the bearing surface of the first conductor 203, fixing the second conductor 101 to the first conductor 203 and electrically connecting it. This achieves an electrical connection between the electrical device 201, grounding wire 202, lug 107, terminal block 106, cover plate 104, second conductor 101, first conductor 203, grounding stake 204, and earth 205. The current travels within the mobile magnetic grounding device 1 along the lug 107, terminal block 106, cover plate 104, and second conductor 101 to the grounding first conductor 203. The first conductor 203 is an extension of the grounding stake 204, and its function is to conduct the current to the earth through the grounding stake 204, preventing the current from causing harm to the human body. Of course, the second conductor 101 can also be moved along the bearing surface according to the operation situation so that the second conductor 101 is always in a suitable position and will not hinder the construction.

[0039] As can be seen, this mobile magnetic grounding device 1 is simple to operate and easy to learn, requiring no professional electrician to operate, making it a grounding device that can effectively reduce labor costs. This device allows the second conductor 101 to move freely via a first conductor 203, such as a grounding flat iron or steel column, eliminating the need for temporary electrical equipment 201 and repeated disassembly and modification, thus effectively reducing costs.

[0040] In summary, the mobile magnetic grounding device provided by this utility model, in practical applications, involves leading out a PE grounding wire 202 from the temporary electrical equipment 201, fixing it to the mobile magnetic grounding device 1 via a wire lug 107, and fixing the grounding shell to the grounding flat iron via magnetic force. The grounding flat iron is connected to the grounding stake 204 by welding, and the grounding stake 204 is buried in the ground 205. The grounding shell can move freely on the grounding flat iron. In the event of leakage or other situations in the electrical equipment 201, the current can be introduced into the ground through the safety facilities of the mobile magnetic grounding device 1.
