Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, and specifically relates to an electrical engineering grounding device. Background Technology

[0002] Grounding is a core technical measure in electrical engineering, with its core functions being "safe current discharge" and "potential stabilization." On the one hand, by connecting the metal parts of electrical equipment or a point in the circuit to the earth, dangerous currents can be quickly conducted to the earth in the event of equipment leakage, lightning strikes, or short circuits, preventing accidents such as electric shock, equipment damage, or fires. On the other hand, grounding provides a stable zero-potential reference point for power systems and electronic circuits. For example, neutral point grounding in a power system can prevent voltage deviation caused by three-phase load imbalance, and grounding of electronic equipment can ensure signal stability. In addition, it can work with devices such as leakage current protectors to achieve rapid fault detection and protection. Furthermore, grounding through the metal casing can shield electromagnetic interference, ensuring the normal operation of equipment in an electromagnetically compatible environment.

[0003] Currently, the most commonly used grounding rods are made of angle steel, round steel, and steel pipe. The traditional installation method involves one person holding the grounding rod upright while another person uses a hammer to drive it into the ground until it reaches a depth of about 1.5 meters, with one end touching the moist soil. However, this installation method has significant drawbacks. If there is a deviation during the hammering, it can not only cause the grounding rod to tilt but also potentially injure the person holding the rod, resulting in injuries to construction workers and safety accidents. This makes the traditional grounding device impractical. Utility Model Content

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected," "equipped with," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or arrangement, a detachable connection or arrangement, or an integral connection or arrangement. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Terms such as "comprising" as used herein do not exclude the presence or addition of one or more other elements or combinations thereof, and therefore should not be construed as limiting this utility model.

[0028] like Figure 1As shown in the preferred embodiment of this utility model, this embodiment provides an electrical engineering grounding device, including a main rod 1, a blocking pin 3, a grounding rod 4, and a counterweight 12. A guide groove 2 is provided inside the main rod 1, and the grounding rod 4 is slidably connected inside the guide groove 2. In this embodiment, to make it easier for the grounding rod 4 to be inserted into the soil, the bottom of the grounding rod 4 is tapered. Considering ease of wiring and conductivity, the grounding rod 4 is made of aluminum alloy. Aluminum alloy has good conductivity and high hardness, ensuring that the grounding rod 4 is not easily deformed while facilitating the transmission of electricity to the soil. A wiring hole is provided on the grounding rod 4 for easy connection of wiring. A support plate 6 is also fixedly installed on the outer periphery of the bottom of the main rod 1. During installation, the horizontal state of the support plate 6 helps to calibrate the verticality of the main rod 1, preventing the main rod 1 or the grounding rod 4 from tilting, ensuring uniform contact between the grounding rod 4 and the soil, stabilizing the grounding resistance, and preventing localized increases in resistance due to tilting. In soft soil environments, the support plate 6 increases the contact area with the ground, making the grounding rod 4 more stable in the soil; if installed on hard ground (such as concrete pavement), the support plate 6 can be fixed to the ground with bolts, making the main rod 1 stable on the hard base, thus making the device more stable during use. Figure 2 As shown, in other embodiments, if the grounding rod 4 is inserted at a building corner or other location where it is inconvenient to place the support plate 6, the support plate 6 can be removed and the device can be used, depending on the actual situation.

[0029] In the device provided in this embodiment, two handles 11 are fixedly installed on both sides of the top of the main rod 1, allowing the worker to carry and control the offset angle of the device. In other embodiments, such as Figure 3 As shown, the top of the main rod 1 may not have a handle 11, and the offset angle of the device can be controlled directly by the handle 8. Protective sleeves 10 are fitted onto the two handles 11. The protective sleeves 10 can be made of materials such as rubber or silicone, which are elastic and can distribute the pressure of the hand when gripping, reducing soreness after prolonged use. This is especially suitable for the usage scenario of this device, reducing hand discomfort caused by frequent forceful gripping by workers. Furthermore, the outer periphery of the protective sleeve 10 is textured. In this embodiment, the protective sleeve 10 has raised and recessed textures to increase the friction between the worker's palm and the handle 11. In other embodiments, the protective sleeve 10 can also be made of thick fleece or sponge, and its surface can be fitted with textures suitable for the material to increase friction.

[0030] In the device provided in this embodiment, a plurality of slots 7 are formed through the main rod 1. A blocking pin 3 is inserted into each slot 7. The blocking pin 3 cooperates with the grounding rod 4, using the blocking pin 3 to hold the top of the grounding rod 4 in place. The worker lifts the entire main rod 1 to a certain height and then presses it down forcefully, causing the blocking pin 3 to collide with the grounding rod 4, thus inserting the grounding rod 4 into the ground. When the grounding rod 4 has been inserted a certain distance into the ground, the main rod 1 can be lifted, and the position of the blocking pin 3 can be adjusted, inserting it into a lower slot 7. The main rod 1 is then pressed down again, causing the blocking pin 3 to collide with the grounding rod 4 once more, further pushing the grounding rod 4 downwards. This process is repeated until the grounding rod 4 is inserted into the appropriate position in the soil.

[0031] like Figure 4 and Figure 5 As shown, in the device provided in this embodiment, a counterweight 12 is sleeved on the main rod 1, and the counterweight 12 and the main rod 1 are rotatably connected. In this embodiment, in order to reduce the friction between the counterweight 12 and the main rod 1, a plurality of balls 9 are provided on the inner side of the counterweight 12, and all the balls 9 are in rolling connection with the counterweight 12. All the balls 9 are in contact with the main rod 1, and all the balls 9 are also in rolling connection with the main rod 1. The design of the balls 9 makes the friction between the counterweight 12 and the main rod 1 relatively small during rotation. A handle 8 is fixedly installed on the outer side of the counterweight 12, and the two handles 8 facilitate the worker to control the counterweight 12, so that the counterweight 12 can move up and down relative to the grounding rod 4. A protective sleeve 10 with a textured surface is also sleeved on the handle 8 to increase the friction between the worker's palm and the handle 8. A mounting protrusion 13 is fixedly provided at the bottom of the counterweight 12, and a mounting ring 5 is fixedly provided on the outer periphery of the main rod 1. The mounting ring 5 has a mounting groove 14. The mounting protrusion 13 can be embedded in the mounting groove 14 and can slide along the mounting groove 14 to facilitate adjustment of the angle of the handle 8 to adapt to different grounding environments, making the device more convenient to use. In this embodiment, the mounting protrusion 13 is set as a T-shaped protrusion, and the end of the vertical rod is fixedly connected to the counterweight 12. The mounting groove 14 is set as a T-shaped groove that matches the mounting protrusion 13. The horizontal rod and part of the vertical rod of the mounting protrusion 13 are inserted into the mounting groove 14. The horizontal rod of the mounting protrusion 13 cooperates with the mounting groove 14 to restrict the up and down movement of the counterweight 12 along the direction of the main rod 1, ensuring that when the worker lifts the counterweight 12 through the handle 8, the counterweight 12 will not move relative to the main rod 1, ensuring the accuracy and stability of the position between the counterweight 12 and the main rod 1 during operation.

[0032] In use, the device provided in this embodiment first installs the grounding rod 4 into the guide groove 2 and adjusts the position of the blocking pin 3 so that the top of the grounding rod 4 abuts against the blocking pin 3. One worker holds two handles 11 and places the bottom of the grounding rod 4 on the ground, while another worker holds two handles 8 and lifts the entire main rod 1. When the main rod 1 is lifted to a certain height, it is pressed down forcefully, causing the blocking pin 3 to strike the top of the grounding rod 4, thus inserting the grounding rod 4 into the soil. When the grounding rod 4 is inserted to a certain depth, the main rod 1 is lifted, the blocking pin 3 is inserted into the next slot 7, the position of the main rod 1 is readjusted so that the top of the grounding rod 4 abuts against the blocking pin 3 again, and the counterweight 2 and the main rod 1 are lifted again using the handles 8, and the grounding rod 4 is struck down again until it is inserted to the appropriate depth in the soil. After the grounding rod 4 is inserted, the grounding wire is passed through the wiring hole on the grounding rod 4 and fixed to the grounding rod 4. Then, from the rear or side, the other end of the grounding wire is connected to the conductor that needs to be grounded using insulating material, so as to install a grounding wire or make a line connection between the conductor to be grounded and the conductor that has been grounded.

[0033] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
