Description

Technical Field

[0001] This utility model relates to the technical field of safety grounding devices for high-voltage power lines, and in particular to a universal rotatable grounding rod. Background Technology

[0002] Grounding rods, also known as grounding electrodes or grounding grids, are electrical safety devices designed to improve the conductivity of the grounding conductor and reduce the resistivity of the soil outside the conductor. They are often used in conjunction with grounding copper wires and are widely used in various fields such as power, communications, and petrochemicals that require reliable grounding.

[0003] Existing general-purpose rotatable grounding rods are mostly fixed in a straight line, making it impossible to adjust the angle and length. For example, in confined spaces such as 10kV switchgear, the height of the switchgear is often lower than the length of the grounding rod, and the grounding copper busbar has a bend. It is difficult to firmly tighten the grounding wire with a fixed grounding rod, making the operation time-consuming and laborious. At the same time, when dealing with irregular grounding positions or equipment at different heights, it is necessary to replace the grounding rod with one of the corresponding specifications, further increasing the complexity of the operation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing grounding rods are mostly fixed in a straight line, making it impossible to adjust their angle and length. For example, in confined spaces such as 10kV switchgear, the height of the switchgear is often lower than the length of the grounding rod, and the grounding copper busbar has a bend. It is difficult to firmly tighten the grounding wire with a fixed grounding rod, making the operation time-consuming and laborious. In addition, when dealing with irregular grounding positions or equipment at different heights, it is necessary to replace the grounding rod with one of the corresponding specifications, further increasing the complexity of the operation. Therefore, a universal rotatable grounding rod is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a universal rotatable grounding rod, comprising a lower grounding rod, an upper grounding rod at the top of the lower grounding rod, a clamp limiting end on the side of the upper grounding rod away from the lower grounding rod, an adjustment device between the lower and upper grounding rods, the adjustment device comprising a threaded rod disposed inside the lower and upper grounding rods, an installation groove formed on the surface of the lower grounding rod, two installation grooves respectively formed on the surfaces of the upper and lower grounding rods, the bottom of the threaded rod fixedly connected to the interior of the lower grounding rod, a first spring fixedly connected between the upper and lower grounding rods, a nut threadedly connected to the surface of the threaded rod, and the first spring sleeved on the surface of the threaded rod.

[0006] Furthermore, a mounting frame is fitted onto the surface of the upper grounding rod, and a movable groove is provided on the lower surface of the mounting frame. Two movable grooves are respectively provided on both sides of the lower end of the mounting frame.

[0007] Furthermore, a sliding rod is movably connected inside the movable groove, and an arc-shaped ring is fixedly connected to one side of the sliding rod, the arc-shaped ring being disposed inside the mounting frame.

[0008] Furthermore, the arc-shaped ring is snapped onto the surface of the upper grounding rod, and a protective pad is fixedly connected to the surface of the arc-shaped ring, with the protective pad disposed on one side of the arc-shaped plate.

[0009] Furthermore, a connecting plate is fixedly connected between the two sliding rods, and a positioning groove is provided on the surface of the connecting plate. A fixing plate is fixedly connected to one side of the mounting frame.

[0010] Furthermore, a second spring is fixedly connected between the fixing plate and the connecting plate, and the surface of the fixing plate has movable holes.

[0011] Furthermore, a movable rod is movably connected inside the movable hole, the second spring is sleeved on the surface of the movable rod, the movable rod is movably connected inside the movable hole and extends into the interior of the positioning groove, a bushing is fixedly connected to one side of the movable rod, and the other side of the movable rod is fixedly connected to the surface of the protective pad.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, the mounting frame can be sleeved onto the surface of the upper grounding rod during use. Simultaneously, the bushing drives the movable rod through the movable hole and positioning groove to pull it to one side. When the mounting frame is in the appropriate position, the movable rod is loosened, and under the action of the second spring, its arc-shaped ring is fixed to the surface of the upper grounding rod. Then, the grounding rod is rotated to the ground. Simultaneously, the nut rotates on the surface of the threaded rod, pressing the upper end of the grounding rod, causing it to move downwards and shorten. When the nut rotates in the opposite direction, it moves upwards, and the first spring presses the upper end of the grounding rod upwards, extending the grounding rod. In substations, busbar bridges, and other scenarios where the grounding position has significant height differences and complex spatial structures, the adjustment device can flexibly adapt to equipment and lines of different heights. When facing high busbars or voltage testing rings, the extended rod allows for connection from the ground, eliminating the need for climbing. For confined spaces such as switch cabinets, the shortened rod allows for flexible insertion into the interior, avoiding operational obstruction caused by an excessively long rod. If used for ground grounding, the length can be adjusted to make it easier to insert the grounding terminal into the appropriate depth, ensuring a firm grounding and improving the flexibility of the device during use.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a universal rotatable grounding rod, including a lower grounding rod 1, an upper grounding rod 2 is provided on the top of the lower grounding rod 1, a clamp limiting end 3 is provided on the side of the upper grounding rod 2 away from the lower grounding rod 1, and an adjustment device 4 is provided between the lower grounding rod 1 and the upper grounding rod 2.

[0016] The specific settings and functions of its adjustment device 4 will be explained below.

[0017] In this embodiment: the adjusting device 4 includes a threaded rod 41, which is disposed inside the lower grounding rod 1 and the upper grounding rod 2. The surface of the lower grounding rod 1 is provided with an installation groove 43. The bottom of the threaded rod 41 is fixedly connected to the interior of the lower grounding rod 1. A first spring 44 is fixedly connected between the upper grounding rod 2 and the lower grounding rod 1. A nut 42 is threadedly connected to the surface of the threaded rod 41, and the first spring 44 is sleeved on the surface of the threaded rod 41.

[0018] Specifically, an installation frame 45 is fitted onto the surface of the upper grounding rod 2, and a movable groove 46 is provided on the lower surface of the installation frame 45.

[0019] Specifically, a sliding rod 47 is movably connected inside the movable groove 46, and an arc-shaped ring 48 is fixedly connected to one side of the sliding rod 47.

[0020] The aforementioned components achieve the following effect: by rotating and raising the nut 42 on the surface of the threaded rod 41, the length of the grounding rod can be adjusted using the action of the first spring 44, thereby increasing the flexibility of the grounding rod's use. The mounting frame 45 on the surface of the upper grounding rod 2 allows it to be fitted and rotated when needed, and can be quickly disassembled when not in use.

[0021] Specifically, the arc-shaped ring 48 is snapped onto the surface of the upper grounding rod 2, and a protective pad 49 is fixedly connected to the surface of the arc-shaped ring 48.

[0022] Specifically, a connecting plate 410 is fixedly connected between the two sliding rods 47, and a positioning groove 411 is provided on the surface of the connecting plate 410. A fixing plate 413 is fixedly connected to one side of the mounting frame 45.

[0023] Specifically, a second spring 412 is fixedly connected between the fixing plate 413 and the connecting plate 410, and a movable hole 414 is provided on the surface of the fixing plate 413.

[0024] Specifically, a movable rod 415 is movably connected inside the movable hole 414, a second spring 412 is sleeved on the surface of the movable rod 415, the movable rod 415 is movably connected inside the movable hole 414 and extends through the interior of the positioning groove 411, and a bushing 416 is fixedly connected to one side of the movable rod 415.

[0025] The effect achieved by the above components is as follows: by setting the nut 42 to rotate on the surface of the threaded rod 41 while rotating, the nut 42 presses against the upper end of the grounding rod, so the upper end of the grounding rod will move downward and shorten. When the nut 42 rotates in the opposite direction, the nut 42 moves upward, and the first spring 44 will press against the upper end of the grounding rod and move upward, so the grounding rod will be extended. The grounding rod of the adjusting device 4 does not need to frequently change tools. By quickly adjusting the length on site, and with its own rotatable characteristics, a suitable operating angle and length can be quickly found, and the fixing of the grounding clamp and grounding connection can be quickly completed, which greatly shortens the preparation and operation time of grounding work.

[0026] Working principle: When in use, the mounting frame 45 of the adjustment device 4 can be fitted onto the surface of the upper grounding rod 2. During placement, the bushing 416 drives the movable rod 415 to be pulled to one side through the movable hole 414 and the positioning groove 411. When the mounting frame 45 is placed in the appropriate position, the movable rod 415 is loosened. Under the action of the second spring 412, the arc ring 48 is fixed to the surface of the upper grounding rod 2. Then, the grounding rod is rotated to the ground. During rotation, the nut 42 can rotate on the surface of the threaded rod 41. The nut 42 presses the upper end of the grounding rod, so the upper end of the grounding rod will move downward and shorten. When the nut 42 rotates in the opposite direction, the nut 42 moves upward, and the first spring 44 will press the upper end of the grounding rod upward, so the grounding rod will be extended. In substations, bus bridges and other scenarios, the grounding position height varies greatly and the spatial structure is complex. The adjustment device 4 can flexibly adapt to equipment and lines of different heights. When dealing with high-mounted busbars or voltage rings, the extended pole allows for connection from the ground, eliminating the need for climbing. For confined spaces like switchgear, the shortened pole allows for flexible access and avoids operational bottlenecks caused by excessive pole length. When used for ground grounding, the length can be adjusted to allow the grounding terminal to be inserted to the appropriate depth, ensuring a secure grounding connection.
