[0001] This utility model relates to the field of power grounding technology, specifically to a grounding component for power grounding grids that is adaptive to soil environment. Background Technology

[0002] In power systems, the grounding grid is a crucial facility for ensuring the safe operation of power equipment and the safety of personnel. Grounding components, as a key part of the grounding grid, directly affect the grounding effectiveness of the grid.

[0003] When using traditional grounding devices, workers first insert the grounding device into the corresponding soil, and then connect the wire to the connector on top of the grounding device.

[0004] However, since the angle of the connector at the top of the grounding component is fixed, if the angle of the wire changes after the grounding component is fixed, the grounding component needs to be re-fixed by the staff to align the connector with the wire. This leads to frequent disassembly and re-fixation of the grounding component, which can easily damage the soil structure, affect the tightness of the contact between the grounding component and the soil, and thus increase the grounding resistance, reduce the reliability of the grounding system, and increase the risk of electrical equipment being struck by lightning or experiencing leakage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grounding component for power grounding grids that adapts to soil environment. This solves the problem that because the angle of the connector at the top of the grounding component is fixed, if the angle of the wire changes, the grounding component needs to be re-fixed by the staff. This results in frequent disassembly and re-fixing of the grounding component, affecting the tightness of the contact between the grounding component and the soil, which in turn increases the grounding resistance and increases the risk of lightning strikes or leakage hazards to power equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grounding component for power grounding grids that adapts to soil environment, comprising an upper column, a lower column below the upper column, anti-corrosion layers fixedly connected to the upper and lower columns respectively, a hollow plate above the upper column, a connector above the hollow plate, and a rotating mechanism inside the hollow plate; the rotating mechanism comprises a column, a spring, a pawl, a ratchet, and a shaft; the column extends through an opening to the lower part of the hollow plate and is movably connected to the hollow plate; springs are fixedly connected to the side wall of the column and the inner wall of the hollow plate respectively; a pawl is fixedly connected to the side of the column away from the spring; a ratchet is engaged with the outer wall of the pawl; a shaft is fixedly connected to the inner wall of the ratchet; the outer wall of the shaft is rotatably connected to the inner wall of the hollow plate via a sealed bearing; and the top of the shaft is fixedly connected to the bottom of the connector.

[0007] Preferably, the outer wall of the column is slidably engaged with the top of the inner wall of the hollow plate.

[0008] Preferably, an assembly mechanism is provided between the upper column and the lower column; the assembly mechanism includes a sleeve, a first thread and a second thread; the sleeve is fixed to the upper inner wall of the lower column, the outer wall of the sleeve is provided with the first thread, the lower inner wall of the upper column is provided with the second thread, and the outer wall of the first thread is threaded to the second thread.

[0010] Preferably, the outer wall of the connector has a placement hole, the top of the connector has a fixing hole, and the bottom of the fixing hole is connected to the placement hole.

[0011] Preferably, a connecting plate is fixedly connected to the outer wall of the upper column, a ground nail is inserted into the inner wall of the connecting plate, and a disc is fixedly connected to the top of the ground nail.

[0012] Beneficial effects

[0013] This utility model provides a grounding component for power grounding grids that adapts to soil environment. It offers the following advantages: This grounding component, through the cooperation of a column, spring, pawl, ratchet, and rotating shaft, allows for adjustment of the connector angle. This solves the problem that because the connector angle at the top of the grounding component is fixed, changes in the wire angle require frequent re-fixing, leading to reduced contact between the grounding component and the soil, increased grounding resistance, and increased risk of lightning strikes or electrical leakage for power equipment.

[0014] The assembly of the grounding component is achieved through the engagement of the sleeve, the first thread, and the second thread, making it convenient for workers to handle. This solves the problem that traditional integrated grounding components are mostly one piece, resulting in a large size that is difficult for workers to handle and is prone to structural damage due to collisions during transportation, thus making it inconvenient for workers to handle the grounding component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Because the angle of the connector at the top of the grounding component is fixed, if the angle of the wire changes, the grounding component needs to be re-fixed by the staff. This results in frequent disassembly and re-fixation of the grounding component, affecting the tightness of the contact between the grounding component and the soil, which in turn increases the grounding resistance and increases the risk of electrical equipment being struck by lightning or leaking electricity.

[0023] In view of this, the present invention provides a grounding component for power grounding grids that adapts to soil environment. Through the cooperation between the column, spring, pawl, ratchet, and rotating shaft, the angle of the connector can be adjusted. This solves the problem that since the angle of the connector at the top of the grounding component is fixed, if the angle of the wire changes, the grounding component needs to be re-fixed by the staff. This results in frequent disassembly and re-fixing of the grounding component, affecting the tightness of the contact between the grounding component and the soil, which in turn increases the grounding resistance and increases the risk of electrical equipment being struck by lightning or leaking current.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0025] Example 1, by Figure 1-5It is understood that the grounding component for an adaptive soil environment power grounding grid in this case includes an upper column 1, a lower column 2 below the upper column 1, and anti-corrosion layers 3 fixedly connected to the upper column 1 and the lower column 2 respectively. A hollow plate 10 is provided above the upper column 1, and a connector 7 is provided above the hollow plate 10. A rotating mechanism is provided inside the hollow plate 10; the rotating mechanism includes a column 12, a spring 13, a pawl 14, a ratchet 15, and a rotating shaft 16; the column 12 is... The column 12 extends through the opening to the bottom of the hollow plate 10 and is movably connected to the hollow plate 10. Springs 13 are fixedly connected to the side wall of the column 12 and the inner wall of the hollow plate 10 respectively. A pawl 14 is fixedly connected to the side of the column 12 away from the springs 13. A ratchet 15 is engaged with the outer wall of the pawl 14. A rotating shaft 16 is fixedly connected to the inner wall of the ratchet 15. The outer wall of the rotating shaft 16 is rotatably connected to the inner wall of the hollow plate 10 through a sealed bearing. The top of the rotating shaft 16 is fixedly connected to the bottom of the connector 7.

[0026] In the specific implementation process, it is worth noting that the upper column 1, lower column 2, and connector 7 constitute the grounding device. The interior of the upper column 1 and lower column 2 is hollow. The anti-corrosion layer 3 is made of corrosion-resistant metal materials, such as zinc or chromium, which can be selected according to the actual situation. This type of material has a certain degree of conductivity and can form electrochemical protection, thereby improving the anti-corrosion characteristics of the upper column 1 and lower column 2 and adapting to different soil environments. When using the grounding device, the worker inserts the upper column 1 and lower column 2 into the soil at the working position and connects the wire to the connector 7. When it is necessary to adjust the position of the connector 7, the worker first moves the upper column 1 and lower column 2 into the soil at the working position. The column 12 moves within the hollow plate 10, compressing the spring 13. The type of spring 13 can be selected according to the actual situation. The column 12 drives the pawl 14 to move, causing the pawl 14 to disengage from the ratchet 15, thus releasing the connection head 7 from its fixation. Then, the operator rotates the connection head 7, which drives the rotating shaft 16 to rotate. The rotating shaft 16 then drives the ratchet 15 to rotate, aligning the hole on the connection head 7 with the position of the wire. Finally, the operator releases the column 12, and the spring 13 rebounds, causing the pawl 14 to re-engage with the ratchet 15 through its elasticity, thus fixing the connection head 7 in place and allowing the angle of the connection head 7 to be adjusted.

[0027] Furthermore, the upper part of the outer wall of the column 12 is slidably engaged with the top of the inner wall of the hollow plate 10;

[0028] In the specific implementation process, it is worth noting that when the column 12 moves, the column 12 slides in the limiting groove at the top of the inner wall of the hollow plate 10 to guide the column 12.

[0029] Furthermore, an assembly mechanism is provided between the upper column 1 and the lower column 2; the assembly mechanism includes a sleeve 17, a first thread 18 and a second thread 19; the sleeve 17 is fixed to the upper inner wall of the lower column 2, the outer wall of the sleeve 17 is provided with the first thread 18, the lower inner wall of the upper column 1 is provided with the second thread 19, and the outer wall of the first thread 18 is threaded to the second thread 19.

[0030] In the specific implementation process, it is worth noting that after the worker moves the grounding component to the working position, the worker aligns the sleeve 17 with the bottom of the upper column 1, and then the worker rotates the lower column 2. The lower column 2 drives the sleeve 17 to rotate, and the sleeve 17 drives the first thread 18 to rotate. The first thread 18 moves along the second thread 19, thereby assembling the upper column 1 and the lower column 2 together. After completion, the worker stops rotating the lower column 2. A sealing ring can be set at the connection position. The material of the sealing ring can be selected according to the actual situation to improve the sealing performance of the connection position between the upper column 1 and the lower column 2. When it is necessary to move the grounding component as a whole, the worker rotates the sleeve 17 out of the upper column 1 to reduce the overall volume of the grounding component, realizes the assembly of the grounding component, and facilitates the worker's handling of it.

[0031] Furthermore, a connecting block 11 is fixedly connected to the bottom of the hollow plate 10, and the connecting block 11 is fixed to the upper inner wall of the upper column 1 by bolts.

[0032] In the specific implementation process, it is worth noting that the workers insert the connecting block 11 into the top of the upper column 1, and then the workers turn the bolts to fix the connecting block 11, thereby assembling the rotating mechanism.

[0033] Furthermore, the outer wall of the connector 7 is provided with a placement hole 8, the top of the connector 7 is provided with a fixing hole 9, and the bottom of the fixing hole 9 is connected to the placement hole 8;

[0034] In the specific implementation process, it is worth noting that after the staff inserts the wire into the placement hole 8, they rotate the bolt into the fixing hole 9, which is a threaded hole, and rotate the bolt to fix the wire into the placement hole 8, thereby ensuring the reliability of the electrical connection and preventing the wire from becoming loose and causing poor contact.

[0035] Example 2, by Figure 1 and 2 It can be seen that a connecting plate 4 is fixedly connected to the outer wall of the upper column 1, a ground nail 6 is inserted into the inner wall of the connecting plate 4, and a disc 5 is fixedly connected to the top of the ground nail 6.

[0036] In the specific implementation process, it is worth noting that after the staff inserts the upper column 1 and the lower column 2 into the ground, the staff moves the disc 5, and the ground nail 6 moves from the disc 5. Moving the ground nail 6 out of the insertion and connection plate 4 and into the ground can firmly fix the grounding component on the ground, enhance the stability of the grounding component, prevent it from shaking or shifting in the soil, and ensure the grounding effect.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
