[0002] Grounding refers to the connection of the neutral point of power systems and electrical devices, the exposed conductive parts of electrical equipment, and the external conductive parts of devices to the earth via conductors. To prevent lightning strikes, grounding devices need to be installed on transmission lines to guide the current generated by lightning strikes to the earth, preventing the conductors or transmission equipment from being damaged by lightning voltage. Existing grounding piles are generally conical piles buried underground. Conical piles are thick at the top and thin at the bottom, which can easily loosen due to external forces and even be easily pulled out. They are relatively unstable, and the connection point between the grounding pile and the conductor is easily loosened by external forces, resulting in poor contact and failure to properly ground. Therefore, it is necessary to propose an electric grounding pile for power engineering to solve the above problems. Utility Model Content
[0003] The purpose of the utility model is to provide an electric grounding pile for electric power engineering, so as to solve the problem that the conical pile is thick at the top and thin at the bottom and is easily loosened by external force, has relatively poor stability, and the connection position between the grounding pile and the wire is easily loosened by external force, resulting in poor contact and failure to ground normally.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric grounding pile for electric power engineering, comprising a conical pile body, the conical pile body being divided into two sections, the upper section of the conical pile body being a closed cylindrical setting, the lower section of the conical pile body being an open setting, and the lower section of the conical pile body being divided into four parts at equal angles to the axis of the conical pile body, the lower section of the conical pile body being provided with a conical cavity, the upper section of the conical pile body being provided with a threaded groove, and the threaded groove being concentrically arranged with the conical pile body, the threaded groove being connected to the conical cavity, the internal thread of the threaded groove being connected with a bolt, a U-shaped groove being provided on the inner wall of the top of the upper section of the conical pile body, and the U-shaped groove being located on the outside of the threaded groove, a connecting plate being fixedly installed on the inner wall of the bottom of the U-shaped groove, a connecting hole being provided on the connecting plate, and the connecting hole running through both sides of the connecting plate.
[0005] Preferably, a plurality of vertical grooves are formed in the lower section of the conical pile body, and the plurality of vertical grooves are distributed at equal angles to the axis of the conical pile body, and inclined plates are fixedly provided in the vertical grooves.
[0006] Preferably, an annular plate is fixedly sleeved on the outer side of the upper section of the conical pile body.
[0007] Preferably, a cross groove is provided on the upper surface of the bolt, and the cross groove is located at the axial center of the bolt.
[0008] Preferably, the bottom of the lower section of the tapered pile body is tapered.
[0009] The technical effects and advantages of this utility model are:
[0010] 1. Since the lower section of the conical pile body is divided into four parts, and the conical cavity is wide at the top and narrow at the bottom, when the bolt enters the conical cavity, it will squeeze the four parts of the lower section of the conical pile body outward, causing the lower section of the conical pile body to expand. At this time, the diameter of the lower section of the conical pile body is larger than that of the upper section of the conical pile body. Therefore, the conical pile body is not easy to be pulled out and has high stability.
[0011] 2. When the bolt is completely inserted into the conical cavity, the lower surface of the bolt head will contact the grounding wire and rub and pull the grounding wire, so that the grounding wire and the connecting plate are in a tensioned state. Therefore, the contact between the grounding wire and the connecting plate is better. At this time, the lower surface of the bolt head presses on the grounding wire and can stably press the grounding wire. Therefore, even if the grounding wire is affected by external force, the connection position of the grounding wire and the connecting plate will not change, and good contact is always maintained. The conductive performance is good and a good grounding effect can be achieved.
[0012] 3. After the inclined plate follows the conical pile body into the ground, the upper end of the inclined plate can be stuck on the inner wall of the ground pile hole, which can increase the friction between the ground pile and the inner wall of the ground pile hole, further increase the stability of the ground pile, make the ground pile not easy to be pulled out, and have high safety.

The conical pile body 1 is cast from metal and can conduct electric current into the ground. This technology is conventional and will not be described in detail.
[0019] In order to solve the problem that the conical pile is thick at the top and thin at the bottom and is easily loosened due to external force, the stability is relatively poor, and the connection position between the grounding pile and the wire is easily loosened by external force, resulting in poor contact and failure to ground normally, the utility model divides the conical pile body 1 into two sections, the upper section of the conical pile body 1 is a closed cylindrical setting, the lower section of the conical pile body 1 is an open setting, and the lower section of the conical pile body 1 is divided into four parts at equal angles to the axis of the conical pile body 1, the lower section of the conical pile body 1 is provided with a conical cavity 2, the upper section of the conical pile body 1 is provided with a thread groove 3, and the thread groove 3 It is concentrically arranged with the conical pile body 1, and the thread groove 3 is connected with the conical cavity 2.

A connecting plate 6 is fixedly installed on the inner wall of the bottom of the U-shaped groove 5. A connecting hole 7 is provided on the connecting plate 6, and the connecting hole 7 runs through both sides of the connecting plate 6. When working, select a suitable position, use a hammer to knock the conical pile body 1 into the ground, and then insert the grounding wire of the power equipment into the connecting hole 7 on the connecting plate 6, and the grounding wire is connected. The thread is screwed onto the connecting plate 6, and then the bolt 4 is screwed into the thread groove 3 of the upper section of the tapered pile body 1. Since the bolt 4 is threadedly connected to the inner wall of the thread groove 3, under the action of force, the bolt 4 descends into the tapered cavity 2 of the lower section of the tapered pile body 1. Since the lower section of the tapered pile body 1 is divided into four parts, and the tapered cavity 2 is wide at the top and narrow at the bottom, the bolt 4 enters the tapered cavity 2 and squeezes the four parts of the lower section of the tapered pile body 1 outward, causing the lower section of the tapered pile body 1 to expand. At this time, the diameter of the lower section of the tapered pile body 1 is larger than that of the upper section of the tapered pile body 1, so the tapered pile body 1 cannot be It is easy to pull out and has high stability. When the bolt 4 completely enters the conical cavity 2, the lower surface of the bolt head of the bolt 4 will contact the grounding wire and will rub and pull the grounding wire, so that the grounding wire and the connecting plate 6 are in a tensioned state. Therefore, the contact between the grounding wire and the connecting plate 6 is better. At this time, the lower surface of the bolt head of the bolt 4 is pressed on the grounding wire, which can stably press the grounding wire.
