A ground rod for electrical engineering

Abstract

This utility model relates to the field of grounding rod technology and discloses a grounding rod for power engineering. The grounding rod for power engineering includes an extension rod one, an extension rod two at one end of the extension rod one, and an extension rod three at the end of the extension rod one away from the extension rod two. A stabilizing component is provided on the outer wall of the extension rod one. This grounding rod for power engineering has a streamlined, spindle-shaped outer shell with a smooth external curved surface, reducing wind interference and improving the stability of the grounding rod. When the wind direction changes, the spindle-shaped shell rotates around the bearing, causing it to adjust to a streamlined, windward posture, reducing the vibration of the grounding rod and improving its stability during operation. When the live wire shakes, the pendulum, due to inertial hysteresis, will move in the opposite direction relative to the grounding rod, thereby partially offsetting the vibration energy of the grounding rod, playing a vibration damping role, and reducing the impact of power line vibration on the grounding rod.

Description

Technical Field

[0001] This utility model relates to the field of grounding rod technology, specifically a grounding rod used in power engineering. Background Technology

[0002] In power systems, during line maintenance and equipment repair, in order to prevent accidents, a grounding wire needs to be connected between the cable and the ground wire. This is usually achieved with the help of a grounding rod. The grounding wire is fixed to the grounding rod, and then the grounding rod is clamped to the high-voltage line to complete the grounding of the high-voltage electricity.

[0003] According to a public notice (Announcement No.: CN 222107049 U) regarding a grounding rod for power engineering, the above application includes a rod body, a first extension rod inserted at the bottom of the rod body, a second extension rod inserted at the bottom of the first extension rod, a first fixing ring sleeved on the outside of the second extension rod, a second fixing ring sleeved on the outside of the second extension rod, a first side plate fixedly connected to the side of the first fixing ring, a second side plate fixedly connected to the side of the second fixing ring, a first fixing strap provided on the side of the first side plate, and a second fixing strap provided on the side of the second side plate.

[0004] However, in actual use, the aforementioned grounding rods must be installed next to utility poles. Without utility poles, they cannot maintain stability. In areas without utility poles, such as open areas or temporary construction sites, grounding rods cannot be installed on utility poles, affecting the progress of power engineering and limiting their application scenarios. In view of this, we propose a grounding rod for power engineering. Utility Model Content

[0011] Preferably, a connecting sleeve is fixedly connected to the end face of the spindle-shaped shell, and a bolt is threadedly connected to the outer wall of the connecting sleeve. The number of spindle-shaped shells is set to several groups, and the several groups of spindle-shaped shells are fixedly connected by the connecting sleeve and the bolt.

[0012] Preferably, a telescopic rod is sleeved on the end face of the extension rod two, and the end of the telescopic rod away from the extension rod two is fixedly connected to the inner top surface of the housing, and a spring is sleeved on the side wall of the telescopic rod.

[0013] Preferably, one end of the spring abuts against the end face of the extension rod two, and the other end of the spring abuts against the inner top surface of the housing.

[0017] Compared with the prior art, this utility model provides a grounding rod for power engineering, which has the following beneficial effects:

[0018] 1. This grounding rod used in power engineering, through the setting of stabilizing components, forms a triangle with two sets of inclined frames and the live wire. The triangle has stability, which can improve the stability between the grounding rod and the live wire and prevent it from shaking during use. The streamlined shell has a smooth external curved surface, which reduces wind interference and improves the stability of the grounding rod. When the wind direction changes, the shell rotates around the bearing, causing the shell to adjust to a streamlined windward posture, making the airflow more stable, reducing the vibration of the grounding rod, and improving the stability of the grounding rod during operation. When the live wire shakes, the pendulum will move in the opposite direction relative to the grounding rod due to the inertial lag effect, thereby partially offsetting the vibration energy of the grounding rod, playing a vibration reduction role, reducing the impact of wire vibration on the grounding rod, and ensuring the safe conduction of current to the ground wire.

[0019] 2. This grounding rod used in power engineering uses a telescopic rod and spring. The clip pulls the wire downward, and the contact arc plate pushes the wire upward under the elastic action of the spring. This bidirectional force maintains a stable pressure between the live wire and the contact arc plate, ensuring reliable current conduction and improving the contact performance of the grounding rod.

[0029] like Figures 1-8 As shown, this utility model provides a technical solution: a grounding rod for power engineering, including an extension rod 1, an extension rod 2 at one end of the extension rod 1, an extension rod 3 at the end of the extension rod 1 away from the extension rod 2, and a stabilizing component 4 on the outer wall of the extension rod 1. The stabilizing component 4 includes a connecting frame 401, a spindle-shaped shell 402, a connecting sleeve 403, a bolt 404, a mounting frame 405, a bearing 406, a mounting plate 407, an inclined frame 408, a buckle 409, a housing 410, a contact arc plate 411, a conductive cover 412, a hinge rod 413, and a pendulum 414.

[0030] In one embodiment of this utility model, the connecting frame 401 is fixedly connected to the outer wall of the extension rod 1. A shuttle-shaped shell 402 is fixedly connected to the outer wall of the connecting frame 401. A connecting sleeve 403 is fixedly connected to the end face of the shuttle-shaped shell 402. A bolt 404 is threadedly connected to the outer wall of the connecting sleeve 403. Several sets of shuttle-shaped shells 402 are provided. Several sets of shuttle-shaped shells 402 are fixedly connected by the connecting sleeve 403 and the bolt 404.

[0031] Mounting bracket 405 is fixedly connected to the inner wall of shuttle-shaped shell 402. Bearing 406 is fixedly connected to the inner wall of mounting bracket 405. Mounting plate 407 is fixedly connected to the top end face of bearing 406. Inclined bracket 408 is fixedly connected to the top end face of mounting plate 407. Buckle 409 is fixedly connected to the top end face of inclined bracket 408. Two sets of inclined bracket 408 and buckle 409 are provided. The two sets of inclined bracket 408 and live wire form a triangle. The triangle has stability and can improve the stability between grounding rod and live wire. Shell 410 is set on the end face of extension rod 2. Contact arc plate 411 is fixedly connected to the end of shell 410 away from extension rod 2.

[0032] The conductive cover 412 is fixedly connected to the end of the extension rod 3 away from the extension rod 1. The inner top surface of the conductive cover 412 is hinged to a hinge rod 413. The end of the hinge rod 413 away from the conductive cover 412 is hinged to a pendulum 414. The rotation angle between the hinge rod 413 and the conductive cover 412 and the rotation angle between the hinge rod 413 and the pendulum 414 are at a 90-degree angle, allowing the pendulum 414 to rotate at any angle. The contact arc plate 411, the shell 410, the extension rod 1, the extension rod 2, the extension rod 3, and the conductive cover 412 are made of copper. The contact arc plate 411 is in contact with the live wire, and the conductive cover 412 is electrically connected to the ground wire.

[0033] Several sets of shuttle-shaped shells 402 are connected by bolts 404, so that extension rod 1, extension rod 2 and extension rod 3 are connected together. The buckle 409 is fastened to the live wire, and the conductive cover 412 is electrically connected to the ground wire. The two sets of inclined frames 408 and the live wire form a triangle. The triangle has stability, which can improve the stability between the grounding rod and the live wire and prevent it from shaking during use.

[0034] When the wind blows the shuttle-shaped shell 402, the streamlined outer shell of the shuttle-shaped shell 402 has a smooth external curved surface, which allows the airflow to flow along the surface of the shuttle-shaped shell 402 without forming obvious eddies, reducing the wind pressure coefficient, reducing wind interference, and improving the stability of the grounding rod. If the wind direction changes, the airflow distribution on the windward and leeward sides will become asymmetrical. The airflow pressure on the windward side will increase, which will increase the negative pressure on the leeward side. This imbalance will generate a torque that makes the stabilizing component 4 rotate, causing the shuttle-shaped shell 402 to rotate around the bearing 406, prompting the shuttle-shaped shell 402 to adjust to a streamlined windward posture, making the airflow more stable, reducing the vibration of the grounding rod, and improving the stability of the grounding rod during operation.

[0035] When the live wire shakes, the force of the swing is transmitted downwards, causing the stabilizing component 4 and the extension rod 3 to swing. Due to the inertial hysteresis effect, the pendulum 414 will move in the opposite direction relative to the grounding rod, thereby partially offsetting the vibration energy of the grounding rod, playing a vibration reduction role, reducing the impact of wire vibration on the grounding rod, and ensuring that the current is safely conducted into the ground wire.

[0036] In addition, a telescopic rod 5 is sleeved on the end face of the extension rod 2. The end of the telescopic rod 5 away from the extension rod 2 is fixedly connected to the inner top surface of the housing 410. A spring 6 is sleeved on the side wall of the telescopic rod 5. One end of the spring 6 abuts against the end face of the extension rod 2, and the other end of the spring 6 abuts against the inner top surface of the housing 410. The buckle 409 pulls the wire down, and the contact arc plate 411 pushes the wire up under the elastic action of the spring 6. This bidirectional force keeps the pressure between the live wire and the contact arc plate 411 stable, ensuring reliable current conduction and improving the contact performance of the grounding rod.

[0037] In this invention, during use, several sets of shuttle-shaped shells 402 are connected by bolts 404, connecting extension rod 1, extension rod 2, and extension rod 3. The buckle 409 is fastened to the live wire, and the conductive cover 412 is electrically connected to the ground wire. The two sets of inclined frames 408 and the live wire form a triangle. The triangle provides stability, improving the stability between the grounding rod and the live wire. When the wind blows the shuttle-shaped shells 402, the streamlined outer shell of the shuttle-shaped shells 402 has a smooth external curved surface, allowing airflow to flow along the surface of the shuttle-shaped shells 402 without forming obvious vortices, reducing the wind pressure coefficient and lowering the wind speed. When there is low wind interference, the wind direction changes, and the airflow distribution on the windward and leeward sides becomes asymmetrical. The airflow pressure on the windward side increases, which increases the negative pressure on the leeward side. This imbalance generates a torque that causes the stabilizing component 4 to rotate, causing the shuttle-shaped shell 402 to rotate around the bearing 406. This causes the shuttle-shaped shell 402 to adjust to a streamlined windward posture, making the airflow more stable. Due to the inertial lag effect, the pendulum 414 will move in the opposite direction relative to the grounding rod, thereby partially offsetting the vibration energy of the grounding rod, playing a vibration reduction role, and reducing the impact of power line vibration on the grounding rod.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
