Description

Technical Field

[0001] This utility model relates to the technical field of power equipment, and in particular to a power grounding device. Background Technology

[0002] With the continuous development of power systems, grounding devices play an increasingly important role in ensuring the safe operation of electrical equipment. The main function of a grounding device is to create a low-impedance fault current path, effectively diverting dangerous energy to the ground, protecting personal safety, equipment safety, and system stability. However, in practical applications, traditional power grounding devices have some problems in fixing the grounding stakes. Specifically, grounding stakes are usually installed on open ground, and when the stakes are impacted, their fixation performance is poor, making them prone to tipping over, especially on uneven ground.

[0003] The related technology, with publication number CN221708958U, describes a power grounding pile, including a pile body. A connecting block is fixedly connected to the pile body, and a support rod is rotatably connected to the bottom of the connecting block. There are three support rods. Slide rails are provided on both sides of the inner bottom wall of the pile body and the support rods. Insert rods are slidably connected to the slide rails. The insert rods can be inserted into the ground to fix the pile body. Limit screws are provided at the bottom of the front of both the pile body and the support rods. This utility model provides a power grounding pile with insert rods. Grounding piles are usually installed on open ground. When the pile body is impacted, the pile body and support rods cannot be properly fixed to the ground. On uneven ground, the support frame is prone to tipping over upon impact. Collapse can affect the grounding system of connected buildings or equipment. Inserting the insert rods into the ground and using limit screws to secure them prevents the telescopic rods and support rods from tipping over, making the fixation more stable.

[0004] The aforementioned technology uses a stake to more firmly fix the grounding stake to the ground, thereby improving the overall structural stability. However, while this method improves the fixing effect to some extent, it does not fully consider the different sizes of grounding plates, undoubtedly limiting the grounding device's ability to effectively conduct energy into the earth, thus affecting the overall system stability and safety performance. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a power grounding device. The fixing unit fixes the grounding plate to the ground through anchors. The adjusting component allows the first and second pressing plates to open and press the upper surface of the grounding plate, thereby ensuring that the lower surface of the grounding plate always keeps in contact with the ground, thus effectively transferring the load and ensuring the stability of the grounding plate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a power grounding device, including a grounding plate and a fixing unit for fixing the grounding plate;

[0007] The fixing unit includes an anchor penetrating the grounding plate, a first clamping plate hinged to one side of the anchor, a second clamping plate hinged to the other side of the anchor, connecting pins respectively disposed at the connection points between the first and second clamping plates and the anchor, and an adjustment component for adjusting the first and second clamping plates.

[0008] By adopting the above technical solution, the grounding plate is used to bear and transfer loads to the ground; the anchor fixes the grounding plate through its through structure and provides connection points; the first clamping plate and the second clamping plate are connected to the anchor by hinge, and can be opened or closed under the action of the adjustment component, thereby pressing the upper surface of the grounding plate; the adjustment component is used to adjust the distance between the first clamping plate and the second clamping plate so that they can fit more tightly against the upper surface of the grounding plate.

[0009] As a preferred embodiment, the adjusting assembly includes a first locking plate slidably connected to the inner side of the first pressing plate, a second locking plate slidably connected to the inner side of the second pressing plate, a connecting plate for connecting the first locking plate and the second locking plate, a connecting plate fixedly connected to the middle position of the connecting plate, an adjusting screw rotating with the connecting plate, and an adjusting sleeve fixedly connected to the upper end face of the anchor and adapted to the adjusting screw. The inner sides of the first locking plate and the second locking plate are set as right angle sides, and a guide protrusion slidably connected to the right angle side is fixedly provided inside the anchor.

[0010] By adopting the above technical solution, the first and second clamping plates are slidably connected to the guide protrusions inside the anchor through their inner right-angled edges, allowing the first and second locking plates to move smoothly in the vertical direction. The first and second locking plates form a sliding engagement with the guide protrusions inside the anchor, ensuring their stability during vertical movement. A connecting plate connects the first and second locking plates together, and its adjusting screw at its central position engages with an adjusting sleeve fixed to the upper end face of the anchor. Rotating the adjusting screw changes the relative position of the entire connecting plate and even the first and second locking plates.

[0011] As a preferred embodiment, the outer sides of the first locking plate and the second locking plate, and the sides of the first pressing plate and the second pressing plate, are respectively provided as wedge-shaped surfaces, and the inclination of the wedge-shaped surfaces decreases sequentially in their falling direction. The sides of the first pressing plate and the second pressing plate relative to the wedge-shaped surfaces are provided as inclined surfaces, and the inclination of the inclined surfaces increases sequentially in the falling direction of the wedge-shaped surfaces.

[0012] By adopting the above technical solution, when the adjusting screw rotates, the complementary action between the adjusting screw and the adjusting screw sleeve causes the adjusting screw to descend. When the adjusting screw moves downward, it drives the first locking plate and the second locking plate on both sides of the connecting plate to move downward. Then, the cooperation between the wedge-shaped surface and the inclined surface increases the distance between the first pressing plate and the second pressing plate. Conversely, when the adjusting screw is rotated in the opposite direction, the adjusting screw moves upward. When the adjusting screw moves upward, it drives the first locking plate and the second locking plate on both sides of the connecting plate to move upward. Then, the cooperation between the wedge-shaped surface and the inclined surface decreases the distance between the first pressing plate and the second pressing plate, making it suitable for grounding plates of different sizes.

[0013] As a preferred embodiment, a limiting ring is provided on the outer periphery of the adjusting screw relative to one end of the connecting rod, and a rotating groove adapted to the limiting ring is provided on the connecting rod. The limiting ring is circumferentially arranged with the center of the adjusting screw as the center point, and the limiting ring and the rotating groove are interference fit.

[0014] By adopting the above technical solution, the function of the limiting ring is to prevent the connecting rod from rotating due to the rotation of the adjusting screw, thereby ensuring that the adjusting screw can accurately adjust the position of the connecting rod. The rotation of the adjusting screw will not cause the connecting rod to rotate together, because the limiting ring is interference-fitted with the rotation groove on the connecting rod, allowing the limiting ring to rotate smoothly within the rotation groove and guiding the adjusting screw to move along the preset trajectory.

[0015] As a preferred embodiment, it further includes a rolling wheel that is respectively rotated at one end of the first pressing plate and the second pressing plate, which corresponds to one end of the first locking plate and the second locking plate, and the rolling wheel is made of insulating nylon material.

[0016] By adopting the above technical solution, and by assembling rolling wheels at one end of the first and second clamping plates (which correspond to the first and second locking plates) using insulating nylon material, these rolling wheels can reduce friction when they come into contact, thereby reducing wear caused by friction and increasing service life. Furthermore, since the rolling wheels are made of insulating nylon, they can also avoid electromagnetic interference with electrical equipment, improving the product's adaptability to complex environments.

[0017] As a preferred embodiment, the system further includes adjusting springs respectively disposed on the inner sides of the first pressing plate and the second pressing plate, one end of the adjusting spring being fixedly connected to the inner side of the first pressing plate and the second pressing plate respectively, and the inner side of the adjusting spring being fixedly connected to both sides of the guide protrusion respectively.

[0018] By adopting the above technical solution, one end of an adjusting spring is attached to the inner side of the first and second pressing plates, and the other end of the adjusting spring is fixedly connected to both sides of the guide protrusion. In this way, the adjusting spring can automatically adjust the tension according to the relative displacement between the first and second pressing plates, ensuring stable pressure between them.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An electrical grounding device includes a grounding plate 100 and a fixing unit for fixing the grounding plate 100.

[0037] Please refer to details. Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing unit includes an anchor 1 penetrating through the grounding plate 100, a first clamping plate 21 hinged to one side of the anchor 1, a second clamping plate 22 hinged to the other side of the anchor 1, connecting pins 6 respectively disposed at the connection points between the first clamping plate 21 and the second clamping plate 22 and the anchor 1, and an adjustment component for adjusting the first clamping plate 21 and the second clamping plate 22. In this utility model, the grounding plate 100 is used to bear and transmit loads to the ground; the anchor 1 fixes the grounding plate 100 through its penetrating structure and provides a connection point; the first clamping plate 21 and the second clamping plate 22 are connected to the anchor 1 by hinges and can open or close under the action of the adjustment component, thereby pressing the upper surface of the grounding plate 100; the adjustment component is used to adjust the distance between the first clamping plate 21 and the second clamping plate 22 so that they can fit more tightly against the upper surface of the grounding plate 100. The working principle is as follows: the fixing unit fixes the grounding plate 100 to the ground through the anchor 1, and the adjusting component allows the first pressing plate 21 and the second pressing plate 22 to open and press the upper end face of the grounding plate 100, thereby ensuring that the lower end face of the grounding plate 100 always keeps in contact with the ground, thus effectively transferring the load and ensuring the stability of the grounding plate 100.

[0038] Please refer to details. Figure 3 , Figure 4 and Figure 5 The adjusting assembly includes a first locking plate 331 slidably connected to the inner side of the first pressing plate 21, a second locking plate 332 slidably connected to the inner side of the second pressing plate 22, a connecting plate 32 for connecting the first locking plate 331 and the second locking plate 332, a connecting plate 32 fixedly connected to the middle position of the connecting plate 32, an adjusting screw 5 that rotates with the connecting plate 32, and an adjusting screw sleeve 10 fixedly connected to the upper end face of the anchor 1 and adapted to the adjusting screw 5. The inner sides of the first locking plate 331 and the second locking plate 332 are set as right angle sides. A guide protrusion 11 slidably connected to the right angle side is fixedly provided in the anchor 1. The first pressing plate 21 and the second pressing plate 22 are slidably connected to the guide protrusion 11 in the anchor 1 through the right angle side set on their inner sides, so that the first locking plate 331 and the second locking plate 332 can move smoothly in the vertical direction. The first locking plate 331 and the second locking plate 332 respectively form a sliding engagement with the guide protrusion 11 in the anchor 1, ensuring their stability during up and down movement. The connecting plate 32 is used to connect the first locking plate 331 and the second locking plate 332 together, and engages with the adjusting screw 5 at its central position with the adjusting sleeve 10 fixed to the upper end face of the anchor 1. Rotating the adjusting screw 5 can change the relative position of the entire connecting plate 32 and even the first locking plate 331 and the second locking plate 332.

[0039] Please refer to details. Figure 3 , Figure 4 and Figure 5 The outer sides of the first locking plate 331 and the second locking plate 332, and on the side opposite to the first pressing plate 21 and the second pressing plate 22, are respectively configured as wedge-shaped surfaces, with the inclination of the wedge-shaped surfaces decreasing sequentially in their downward direction. The side of the first pressing plate 21 and the second pressing plate 22 opposite to the wedge-shaped surfaces is configured as inclined surfaces, with the inclination of the inclined surfaces increasing sequentially in their downward direction. The wedge-shaped surfaces cooperate with the first pressing plate 21 and the second pressing plate 22, allowing the distance between the first pressing plate 21 and the second pressing plate 22 to be adjusted as needed. Specifically, the inclined surfaces of the first pressing plate 21 and the second pressing plate 22 can interact with the wedge-shaped surfaces of the first locking plate 331 and the second locking plate 332. The adjusting screw 5 can move up and down through its interaction with the adjusting screw sleeve 10, thereby driving the first locking plate 331 and the second locking plate 332 on both sides of the connecting plate 32 to move up and down. When the adjusting screw 5 moves downward, the first locking plate 331 and the second locking plate 332 move downward accordingly. The engagement between the wedge-shaped surface and the inclined surface increases the distance between the first pressing plate 21 and the second pressing plate 22, thus accommodating larger-sized grounding plates 100. Conversely, when the adjusting screw 5 moves upward, the first locking plate 331 and the second locking plate 332 move upward accordingly. The engagement between the wedge-shaped surface and the inclined surface decreases the distance between the first pressing plate 21 and the second pressing plate 22, thus accommodating smaller-sized grounding plates 100. The overall working principle is to control the up-and-down movement of the connecting plate 32 and its first locking plate 331 and second locking plate 332 by rotating the adjusting screw 5, thereby adjusting the distance between the first pressing plate 21 and the second pressing plate 22 to accommodate grounding plates 100 of different sizes.

[0040] Please refer to details. Figure 4 and Figure 5 To prevent the connecting rod 31 from rotating due to the rotation of the adjusting screw 5, a limiting ring 51 is provided on the outer periphery of the adjusting screw 5 relative to one end of the connecting rod 31. The connecting rod 31 has a rotating groove 311 that matches the limiting ring 51. The limiting ring 51 is circumferentially positioned with the center of the adjusting screw 5 as its center point, and the limiting ring 51 and the rotating groove 311 are interference-fitted. The function of the limiting ring 51 is to prevent the connecting rod 31 from rotating due to the rotation of the adjusting screw 5, thereby ensuring that the adjusting screw 5 can accurately adjust the position of the connecting rod 31. The rotation of the adjusting screw 5 will not cause the connecting rod 31 to rotate together because the interference fit between the limiting ring 51 and the rotating groove 311 on the connecting rod 31 allows the limiting ring 51 to rotate smoothly within the rotating groove 311, guiding the adjusting screw 5 to move along a preset trajectory.

[0041] Please refer to details. Figure 2 and Figure 3To reduce the friction between the inner sides of the first and second pressing plates 21 and 22 and the first and second locking plates 331 and 332, rolling wheels 41 are rotatably mounted on the first and second pressing plates 21 and 22 at one end corresponding to the first and second locking plates 331 and 332, respectively. The rolling wheels 41 are made of insulating nylon. By assembling the rolling wheels 41 at one end of the first and second pressing plates 21 and 22 corresponding to the first and second locking plates 331 and 332, and using insulating nylon, these rolling wheels 41 can reduce friction when the two surfaces are in contact, thereby reducing wear caused by friction and improving service life. Furthermore, since the rolling wheels 41 are made of insulating nylon, they can also avoid electromagnetic interference with electrical equipment, improving the product's adaptability in complex environments. The overall working principle is as follows: when the first pressing plate 21 and the second pressing plate 22 come into contact with the first locking plate 331 and the second locking plate 332, the rolling wheel 41 between them can roll along the contact surface instead of sliding, thereby effectively reducing friction and making the pressing process smoother and more efficient.

[0042] Please refer to details. Figure 3 To ensure tension between the first pressing plate 21 and the second pressing plate 22, adjusting springs 42 are respectively disposed inside the first pressing plate 21 and the second pressing plate 22. One end of the adjusting spring 42 is fixedly connected to the inner side of the first pressing plate 21 and the second pressing plate 22, and the inner side of the adjusting spring 42 is fixedly connected to both sides of the guide protrusion 11. One end of the adjusting spring 42 is attached to the inner side of the first pressing plate 21 and the second pressing plate 22, and the other end of the adjusting spring 42 is fixedly connected to both sides of the guide protrusion 11. In this way, the adjusting spring 42 can automatically adjust the tension according to the relative displacement between the first pressing plate 21 and the second pressing plate 22, ensuring stable pressure between them. The working principle is that when the tension is adjusted, the distance between the first pressing plate 21 and the second pressing plate 22 changes. At this time, the adjusting spring 42 will automatically extend and retract to maintain appropriate pressure between the first pressing plate 21 and the second pressing plate 22, thereby ensuring the tightness of the first pressing plate 21 and the second pressing plate 22 pressing against the mating plate 100.

[0043] In this embodiment, during use, the grounding plate 100 is used to bear and transfer the load to the ground. The vertical movement of the connecting plate 32 and its first locking plate 331 and second locking plate 332 is controlled by rotating the adjusting screw 5, thereby adjusting the distance between the first pressing plate 21 and the second pressing plate 22 to accommodate grounding plates 100 of different sizes. During this process, the limiting ring 51 prevents the connecting rod 31 from rotating due to the rotation of the adjusting screw 5, thereby ensuring that the adjusting screw 5 can accurately adjust the position of the connecting rod 31. The rotation of the adjusting screw 5 will not cause the connecting rod 31 to rotate together, because the limiting ring 51 is interference-fitted with the rotating groove 311 on the connecting rod 31, allowing the limiting ring 51 to rotate smoothly in the rotating groove 311 and guiding the adjusting screw 5 to move along the preset trajectory. When the first pressing plate 21 and the second pressing plate 22 contact the first locking plate 331 and the second locking plate 332, the rolling wheel 41 between them can roll along the contact surface instead of sliding, thereby effectively reducing friction and making the pressing process smoother and more efficient.

[0044] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
