[0021] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0022] like Figure 1 The illustration shows a simple temporary grounding wire insertion device, comprising: a grounding rod 1, a handle 2, a terminal block 3, and a fixing bolt 5. The grounding rod 1 has a conical base and a handle 2 connected to its top, serving as the point of force application when inserting or removing the grounding rod 1. The terminal block 3 is mounted on the upper end of the grounding rod 1. Scale lines 4 are provided on the grounding rod 1 at the bottom of the terminal block 3 to control the insertion depth. A warning sign is installed on the handle 2 to prevent approaching or accidentally touching the device.
[0023] like Figure 2 The terminal block 3 shown is a cubic structure. Adjacent surfaces of the terminal block 3 have insertion holes and threaded holes. The insertion holes are vertically oriented and extend into the interior of the terminal block 3, forming a limiting groove within it. The grounding wire is inserted into the terminal block 3 and stripped. The threaded hole is located on the side of the terminal block 3 and communicates with the insertion hole. A fixing bolt 5 is rotatably connected to the threaded hole, with its end contacting the stripped section of the grounding wire and securing it in the terminal block 3. To increase the contact area for better conductivity and enhance the limiting effect to prevent the grounding wire from detaching from the terminal block 3, a limiting piece is connected to the end of the fixing bolt 5 that contacts the grounding wire. This limiting piece is circular and serves to increase the contact area between the fixing bolt 5 and the grounding wire, while also protecting the fixing bolt 5 and preventing it from detaching from the threaded hole.
[0024] The grounding rod 1 is made of round stainless steel with a certain diameter, which can withstand the force required for grounding without deformation. The handle 2 is made of round stainless steel with a certain diameter, which can withstand the force required for grounding without deformation. The terminal block 3 is made of cubic stainless steel with a certain side length, which is not easy to rust when exposed to rain. The scale lines 4 are marked so that they can be easily observed when grounding.
[0025] Specifically, the grounding rod is made of stainless steel with a diameter of 16mm and a length of 800mm, with one end tapered to a length of 100mm, to facilitate the insertion of the grounding wire into the ground during construction. The handle 2 is made of stainless steel with a diameter of 20mm and a length of 150mm, welded to the top of the grounding rod 1 (untapered section), increasing torque and making it easier to insert or remove the grounding rod 1. The terminal block 3 is made of cubic stainless steel with a side length of 10mm, with a 5mm diameter circular hole and a 4mm threaded hole drilled on two adjacent faces respectively. The fixing bolt 5 is a single M4×0.5×8 round head bolt. Scale lines 4 are engraved on the grounding rod 1 at 500mm, 600mm, and 700mm from the tapered tip, respectively, and marked with the numbers 500mm, 600mm, and 700mm.
[0026] The handle 2 is used as the point of force application and transmits the force to the grounding rod 1. The grounding rod 1 is inserted into the ground, and the insertion depth is controlled by the scale line 4. The grounding wire is connected to the terminal block 3. Unsafe charges or leakage currents caused by various reasons are conducted to the earth through the stripped section of the grounding wire, the fixing bolt 5, the terminal block 3, and the grounding rod 1.
[0027] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
