Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a grounding rod and a grounding device. Background Art

[0002] In recent years, people have higher and higher requirements for power supply reliability. Power companies are using various methods to shorten construction and emergency repair time to ensure continuous power supply to customers. However, in order to ensure the safety of personnel during maintenance work, power companies must hang multiple sets of grounding wires according to the on-site conditions to ensure the personal safety of maintenance workers.

[0003] There are two types of grounding rods commonly used in power systems today: spiral compression type and spring compression type. Both methods have their own advantages and disadvantages. The spiral compression type has a reliable contact surface, but the operation time is long. The spring compression type can greatly shorten the operation time, but due to the problem of spring aging, the contact surface will not be reliable. Therefore, many users use spiral compression type grounding rods, which have a longer operation time and a reliable contact surface.

[0004] In the existing spiral compression grounding rod, the operating handle and the internal components are fastened by screws. When the operating handle is repeatedly operated, the fixing hole for installing the screw will expand, which affects the use effect and the user experience is low. In addition, the exposed screw head will wear the insulating gloves, which will harm the health of the operator and the safety is low. In addition, the multifunctional grounding pin has the problem that the C-type spring buckle is aged and cannot clamp the grounding rod, causing the grounding rod to fall out of the C-type spring buckle during transportation.

[0059] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0060] like Figure 1 As shown, this embodiment provides a grounding device, including a multifunctional grounding pin 200, a grounding rod 100 and an electric wire 300. The two ends of the electric wire 300 are electrically connected to the multifunctional grounding pin 200 and the grounding rod 100 respectively. The electric wire 300 is specifically a multi-strand soft copper core wire. When in use, the multi-strand soft copper core wire needs to be removed from the multifunctional grounding pin 200, and the multifunctional grounding pin 200 is driven into the ground as a grounding body. Then the grounding rod 100 is fixed to the conductor of the equipment that has been powered off and confirmed to be without voltage, and then the operator can perform the operation. The multifunctional grounding pin 200 not only has the function of a grounding body, but also has the function of storing the electric wire 300 and the grounding rod 100. Specifically, a bayonet 201 is provided on one side of the multifunctional grounding pin 200 close to the grounding rod 100, and a fixing groove 121 (such as Figure 4 As shown), the fixing groove 121 is engaged with the bayonet 201 .

[0061] The grounding device provided in this embodiment is provided with a bayonet 201 on one side of the multifunctional grounding pin 200 close to the grounding rod 100, and a fixing groove 121 is provided on the grounding rod 100 corresponding to the bayonet 201, and the fixing groove 121 is engaged with the bayonet 201, so as to realize the position fixation of the multifunctional grounding pin 200 to the grounding rod 100, and the fixing effect is good, and the grounding rod 100 is prevented from falling out of the bayonet 201, which is more convenient to use and improves the working efficiency; when in use, the wire 300 and the grounding rod 100 can be quickly combined into a whole, which is convenient for storage and transportation, saving the working time of the operator and reducing the labor intensity.

[0062] This embodiment also provides a grounding rod 100, such as Figure 2-3 As shown, the ground rod 100 includes a hook 1, a crimping assembly 2, an insulating outer tube 3, a first operating tube 4, a screw 5 and a transmission assembly 6. The top of the hook 1 has a hook 11, which is used to hook on the wire of a device that is confirmed to be voltage-free. The crimping assembly 2 is slidably arranged on the hook 1, and the crimping assembly 2 can slide in a direction close to the hook 11 to achieve the fixation of the wire between the crimping assembly 2 and the hook 1. The bottom of the hook 1 is provided with an insulating outer tube 3, which is made of insulating material and plays the role of insulation and isolation. The first operating tube 4 is at least partially sleeved on the outside of the insulating outer tube 3, and a clamping block 41 is arranged on the inner wall of the first operating tube 4. The operator realizes the driving of the power by operating the first operating tube 4 to rotate. The screw rod 5 is passed through the first operating tube 4 and the insulating outer tube 3 and connected to the crimping assembly 2. A transmission assembly 6 is sleeved on the screw rod 5. One side of the transmission assembly 6 can abut against the screw rod 5 and be transmission-connected therewith. The other side is provided with a card slot 631 corresponding to the card block 41. The card block 41 is carded in the card slot 631 (such as Fig. 9 and Fig.10 shown).

[0063] The grounding rod 100 provided in this embodiment, when the wire needs to be fixed, after the hook member 1 is hooked on the wire, the operator rotates the first operating tube 4, and the clamping block 41 of the first operating tube 4 is clamped in the clamping groove 631 of the transmission assembly 6, so that the first operating tube 4 is connected to the screw rod 5 through the transmission assembly 6. As the first operating tube 4 rotates, while the screw rod 5 rotates, it can also move along its own axial direction. Driven by the screw rod 5, the crimping assembly 2 connected to the screw rod 5 is ejected from the hook member 1, thereby achieving the clamping of the hook member 1 and the crimping assembly 2 from both sides of the wire.

[0064] By sliding the crimping assembly 2 with the hook 1, the wire clamp is arranged between the hook 1 and the crimping assembly 2, so as to fix the wire, and the fixing effect of the wire is good. By cooperating with the crimping assembly 2, the first operating tube 4, the screw 5 and the transmission assembly 6, the first operating tube 4 is rotated, and the crimping assembly 2 is moved under the transmission action of the screw 5 and the transmission assembly 6, and the crimping effect is good. By providing a clamping block 41 on the inner wall of the first operating tube 4, and providing a clamping groove 631 corresponding to the clamping block 41 on the other side of the transmission assembly 6, the clamping block 41 is clamped in the clamping groove 631, so that the first operating tube 4 and the transmission assembly 6 are clamped in the clamping groove 631, the clamping groove 631 and the clamping block 41 are not easy to wear and tear compared with the screw locking pair in the prior art, the fixing effect is good, and the use effect will not be affected by looseness, and the user experience is good. At the same time, the clamping groove 631 and the clamping block 41 are inside the first operating tube 4, and will not be exposed to the first operating tube 4, and will not wear the insulating gloves, so as to ensure the personal safety of the operator, and the safety is high.

[0065] Furthermore, if Figure 4 As shown, a fixing seat 12 is provided at one end of the hook member 1 away from the hook 11. The fixing seat 12 has a cylindrical shape. A fixing groove 121 is provided on the outer wall of the fixing seat 12. The fixing groove 121 is used to clamp the bayonet 201 of the multifunctional grounding pin 200. A connecting piece 13 is provided on one side of the fixing seat 12. Two connecting holes are provided on the connecting piece 13. The connecting bolts are respectively passed through the connecting holes and the wiring ears of the wire 300 to achieve electrical connection between the grounding rod 100 and the wire 300. A first threaded hole is provided in the fixing groove 121. A second threaded hole is provided at the upper end of the insulating outer tube 3. The bolts are respectively passed through the first threaded hole and the second threaded hole to fix the insulating outer tube 3 to the hook member 1.

[0066] Furthermore, if Figure 5As shown, the crimping assembly 2 includes a crimping piece 21 and a connecting plate 22. One of the crimping piece 21 and the hook piece 1 is provided with a guide groove, and the other is provided with a guide rail. The guide rail is slidably matched with the guide groove, so that the crimping piece 21 can slide relative to the hook piece 1 in a direction close to or away from the hook 11. A circular arc groove is provided at the top of the crimping piece 21. The size of the circular arc groove is adapted to the angle of the hook 11 of the hook piece 1. The hook 11 and the circular arc groove can be closed to form a circular through hole. The circular through hole is used for the wire to pass through so as to clamp and fix the wire. A connecting plate 22 is provided at the bottom of the crimping piece 21. The connecting plate 22 is used to connect the screw rod 5. The connecting plate 22 is fixed to the bottom of the crimping piece 21 by bolts, and the connecting plate 22 plays the role of an intermediate connection.

[0067] It is understandable that the connecting plate 22 can be directly connected to the screw rod 5, and the screw rod 5 can directly drive the crimping member 21 through the connecting plate 22, which has a simple structure, small assembly links, and low assembly difficulty. However, the screw rod 5 needs to be relatively long, which is not conducive to production and processing.

[0068] In order to solve this problem, the connecting plate 22 is connected to the screw rod 5 through a connecting assembly, and the connecting assembly includes a connecting shaft 7, which is arranged inside the insulating outer tube 3, and the diameter of the connecting shaft 7 is smaller than the inner diameter of the insulating outer tube 3, and the connecting shaft 7 passes through the hook piece 1 and is connected to the connecting plate 22 of the crimping assembly 2. Specifically, there are two connecting plates 22, and the two connecting plates 22 are arranged in parallel and spaced apart. A T-shaped stopper 71 is arranged on the top of the connecting shaft 7, and the large end of the T-shaped stopper 71 is located on the top surface of the connecting plate 22, and the small end of the T-shaped stopper 71 is located between the two connecting plates 22.

[0069] This structure ensures the connection between the connecting plate 22 and the connecting shaft 7 while having a strong bearing capacity. At the same time, the connecting shaft 7 and the connecting plate 22 are not rigidly connected, and the T-shaped stopper 71 can rotate relative to the connecting plate 22, so that the connecting shaft 7 can have a certain activity space, and the top of the large end of the T-shaped stopper 71 can directly abut the bottom of the crimping piece 21, ensuring that the connecting shaft 7 can directly act on the crimping piece 21 with the power provided.

[0070] Furthermore, if Figure 3 As shown, the connection assembly further includes an insulating inner tube 8, the diameter of the insulating inner tube 8 is smaller than the inner diameter of the insulating outer tube 3, so that the insulating inner tube 8 is arranged inside the insulating outer tube 3. The insulating inner tube 8 is made of insulating material, such as plastic, etc., which has an insulating effect. The two ends of the insulating inner tube 8 are respectively connected to the connecting shaft 7 and the screw 5. Specifically, the upper end of the insulating inner tube 8 is connected to the end of the connecting shaft 7 away from the crimping assembly 2 by bolts, and the lower end of the insulating inner tube 8 is connected to the screw 5 by bolts.

[0071] The insulating inner tube 8 not only has an insulating effect, but also has a lengthening effect, and the insulating inner tube 8 is relatively long. In actual use, the slender pipe between the connecting shaft 7 and the screw 5 is prone to bending during power transmission, which causes the insulating inner tube 8 to bend and affect the use effect.

[0072] In order to solve this problem, the ground rod 100 further includes a positioning ring 9, which is sleeved on the insulating inner tube 8 and located between the insulating inner tube 8 and the insulating outer tube 3. If the insulating inner tube 8 has a tendency to bend, the outer wall of the positioning ring 9 abuts against the inside of the insulating outer tube 3 to force the insulating inner tube 8 to correct the bending position, so as to ensure that the insulating inner tube 8 can always be straight. The positioning ring 9 is specifically an insulating tube plug, and the positioning ring 9 is made of plastic material, which further enhances the insulation effect.

[0073] Furthermore, if Figure 6-10 As shown, a transmission assembly 6 is provided at the lower end of the insulating inner tube 8, and the transmission assembly 6 includes a spinning seat 61, a pressing block 62, a transmission member 63 and an elastic member 64. The spinning seat 61 is sleeved on the screw 5 and connected to the crimping assembly 2, and the spinning seat 61 plays the role of an intermediate connection. The pressing block 62 is arranged in the spinning seat 61 along the radial sliding of the spinning seat 61 and can abut against the screw 5. One side of the transmission member 63 can slide with the outer wall of the spinning seat 61 and the outer wall of the pressing block 62 respectively, and the other side is provided with a card groove 631. The elastic member 64 is specifically a reset spring, and the elastic member 64 is located between the spinning seat 61 and the pressing block 62 and can abut against them respectively, and the elastic member 64 plays the role of elastic reset.

[0074] If it is necessary to tighten the wire, when the first operating tube 4 is operated to rotate, since the slot 631 of the transmission member 63 and the block 41 of the first operating tube 4 are engaged with each other, the transmission member 63 slides along the circumference of the spinning seat 61 driven by the first operating tube 4, and when the transmission member 63 slides to the outside of the pressing block 62, the pressing block 62 moves toward the direction close to the screw 5 and along the radial direction of the screw 5, and the pressing block 62 gradually compresses the elastic member 64, so that the pressing block 62 abuts against the threaded section of the screw 5, thereby realizing the transmission connection between the first operating tube 4, the transmission member 63, the pressing block 62 and the screw 5 in sequence, and continuing to operate the first operating tube 4 to rotate, the screw 5 and the pressing block 62 are equivalent to a screw nut pair, and the screw 5 can rotate along its own axial direction while also moving along its own axis, thereby realizing the abutment between the crimping assembly 2 and the wire.

[0075] If it is necessary to disengage the wire, when the first operating tube 4 is operated to rotate in the reverse direction, the driving member 63 slides in the reverse direction along the circumference of the spin pressing seat 61 under the drive of the first operating tube 4 because the slot 631 of the transmission member 63 and the block 41 of the first operating tube 4 are mutually engaged. When the transmission member 63 slides over the outer side of the pressing block 62, the transmission member 63 no longer presses against the pressing block 62 and disengages from it. Under the self-restoring force of the compressed elastic member 64, the elastic member 64 pushes the pressing block 62 to move away from the screw rod 5, so that the pressing block 62 and the screw rod 5 are disengaged, resulting in the interruption of the transmission connection between the first operating tube 4, the transmission member 63, the pressing block 62 and the screw rod 5. Then the first operating handle is moved downward to drive the spin pressing seat 61, the insulating inner tube 8, the screw rod 5, the connecting shaft 7 and the crimping assembly 2 to move away from the hook member 1, so as to open the hook 11 of the hook member 1, so as to facilitate the wire to be disengaged from the hook member 1.

[0076] Furthermore, the spinning seat 61 includes a first connecting part, an intermediate connecting part and a second connecting part, the two ends of the intermediate connecting part are respectively connected to the first connecting part and the second connecting part, the first connecting part is provided with a first axial hole along its axial direction, the intermediate connecting part is provided with a second axial hole along its axial direction, and the second connecting part is provided with a third axial hole along its axial direction, and the axes of the first axial hole, the second axial hole and the third axial hole are collinear and interconnected. The first axial hole is used to accommodate the lower end of the insulating inner tube 8 and the upper end of the screw 5, and the threaded sections of the screw 5 pass through the second axial hole and the third axial hole respectively. The upper end of the screw 5 extends into the lower end of the insulating inner tube 8, and the insulating inner tube 8 extends into the first connecting part. A first mounting hole is provided on the outer periphery of the first connecting part, and bolts are sequentially passed through the first mounting hole, the insulating inner tube 8 and the screw 5 to connect into an integral structure.

[0077] A slide groove 611 is provided on the outer wall of the second connection part of the spin-press seat 61 along its circumferential direction, and a receiving groove 612 is provided on the outer wall of the second connection part of the spin-press seat 61 along its axial direction. The receiving groove 612 is connected to the slide groove 611 and the second axial hole. The receiving groove 612 is used to accommodate the pressing block 62, and the transmission member 63 slides and fits in the slide groove 611 and the pressing block 62 respectively. By setting the slide groove 611 on the outer peripheral wall of the spin-press seat 61, a sliding space is provided for the sliding of the transmission member 63, and the sliding fit between the transmission member 63 and the slide groove 611 plays a guiding role. At the same time, the side wall of the slide groove 611 plays a role of limiting the transmission member 63, so that when unlocking is required, the transmission member 63 and the spin-press seat 61 can move axially with the first operating tube 4. The bottom of the middle of the receiving groove 612 is a through hole structure, so that the receiving groove 612 is connected with the second shaft hole, so that the pressing block 62 can pass through the receiving groove 612 and enter the second shaft hole to achieve the abutment between the pressing block 62 and the screw rod 5. The bottom of the groove on both sides of the receiving groove 612 is not a through hole structure, which provides a receiving space for the elastic member 64.

[0078] It can be understood that the diameter of the middle connecting part is larger than the diameters of the first connecting part and the second connecting part, the first operating tube 4 matches the size of the spinning seat 61, the upper end of the first operating tube 4 is a small tube end, and the lower end of the first operating tube 4 is a large tube end, and the diameter of the large tube end is larger than the diameter of the small tube end, so that the large tube end can accommodate the middle connecting part, and the small tube end can accommodate the first connecting part. While meeting the structural requirements, the structure is optimized and the waste of raw materials is reduced.

[0079] Furthermore, the pressing block 62 includes a bite portion and a limit portion, and the two limit portions are symmetrically arranged on both sides of the bite portion, and the inner side of the limit portion is used to abut against the elastic member 64 to limit the elastic member 64. The inner side of the bite portion in the pressing block 62 is provided with a thread matching the screw rod 5, and the outer wall of the bite portion in the pressing block 62 is provided with an avoidance groove 621 along the circumference of the spin-pressing seat 61, and the avoidance groove 621 is connected to the slide groove 611. The avoidance groove 621 and the slide groove 611 are both arc structures, and the radius of the two is the same, and the transmission member 63 is slidably matched with the slide groove 611 and the avoidance groove 621 respectively. When the transmission member 63 slides into the avoidance groove 621, both ends of the transmission member 63 are still in the slide groove 611, the transmission member 63 contacts the pressure block 62, and the pressure block 62 engages with the thread of the screw rod 5 for transmission connection; when the transmission member 63 slides into the slide groove 611, the transmission member 63 does not enter the avoidance groove 621, the transmission member 63 does not contact the pressure block 62, and the pressure block 62 does not engage with the thread of the screw rod 5, and the transmission connection is interrupted.

[0080] Furthermore, the transmission member 63 is specifically an arc pin, and at least two slots 631 are arranged on the outer wall of the transmission member 63, and at least two blocks 41 are arranged on the inner wall of the first operating tube 4 along its axial direction, and each block 41 is engaged with a slot 631. With this structure, the connection stability between the first operating tube 4 and the transmission member 63 is ensured. At the same time, the distances between the multiple blocks 41 and the end face of the first operating tube 4 are different, and one of the blocks 41 extends inwardly from the end face of the first operating tube 4 along its axial direction. With this structure, when the transmission member 63 is installed, the block 41 is easy to align with the slot 631, and the positioning effect is good. The block 41 has a guiding effect on the slot 631, which is convenient for the transmission member 63 to slide from the end face of the first operating tube 4 to the inside, which provides great convenience for installation.

[0081] Furthermore, a limiting block is provided on the inner wall of the first operating tube 4 along its circumference, and a limiting block is provided between two adjacent clamping blocks 41. The transmission member 63 abuts against the limiting block on the side along the axial direction of the first operating tube 4, and the limiting block plays a role in limiting the transmission member 63. A protrusion 632 is formed between two adjacent clamping grooves 631 of the transmission member 63, and the two sides of the protrusion 632 along the circumference of the first operating tube 4 abut against the two clamping blocks 41 respectively, and the side of the protrusion 632 along the axial direction of the first operating tube 4 abuts against the limiting block, so that the protrusion 632 is well limited in three directions, and the fixing effect is good, thereby ensuring the stability of the connection between the first operating tube 4 and the transmission member 63.

[0082] In order to facilitate the operator to perform the rotation operation, such as Figure 2-Figure 3 As shown, the ground rod 100 also includes a connecting tube 10 and a second operating tube 14. The connecting tube 10 is made of an insulating material, preferably plastic. The connecting tube 10 is sleeved on the outside of the screw 5 and connected thereto, and the connecting tube 10 plays the role of intermediate connection and extension. The second operating tube 14 is sleeved on the outside of the connecting tube 10 and connected to the screw 5. The second operating tube 14 and the first operating tube 4 are configured to rotate in opposite directions. In actual use, the operator's hands hold the first operating tube 4 and the second operating tube 14 respectively, which is convenient for screwing the screw 5, so that the screwing stroke of the screw 5 is larger, saving the operator's time and reducing labor intensity.

[0083] Optionally, a positioning ring 15 is provided on the outside of the connecting tube 10, and the positioning ring 15 is located between the connecting tube 10 and the second operating tube 14. The positioning ring 15 and the positioning ring 9 have the same working principle, which reduces the bending of the connecting tube 10 during movement and ensures the use effect.

[0084] The working process of the grounding rod 100 provided in this embodiment is as follows:

[0085] During actual use, the operator holds the first operating tube 4 and the second operating tube 14 with both hands respectively and rotates them in opposite directions. The transmission member 63 slides along the slide groove 611 of the spinning seat 61 under the drive of the first operating tube 4. When the transmission member 63 slides into the avoidance groove 621 of the pressure block 62, the pressure block 62 moves toward the direction close to the screw 5 and along the radial direction of the screw 5. The pressure block 62 gradually compresses the elastic member 64, so that the pressure block 62 abuts against the threaded section of the screw 5 and bites, thereby realizing the transmission connection between the first operating tube 4, the transmission member 63, the pressure block 62 and the screw 5 in sequence, and continuing to operate the first operating tube 4 and the second operating tube 14 to rotate. The screw 5 and the pressure block 62 are equivalent to a screw nut pair. While the screw 5 rotates along its own axial direction, it can also move along its own axis, thereby realizing the abutment between the crimping member 21 of the crimping assembly 2 and the wire;

[0086] If it is necessary to detach the wire, when the first operating tube 4 and the second operating tube 14 are respectively rotated in the opposite direction, the transmission member 63, driven by the first operating tube 4, slides in the opposite direction along the slide groove 611 of the spin pressing seat 61. When the transmission member 63 slides through the avoidance groove 621 of the pressing block 62, the transmission member 63 no longer presses against the pressing block 62 and detaches from it. Under the self-restoring force of the compressed elastic member 64, the elastic member 64 pushes the pressing block 62 to move away from the screw rod 5, so that the pressing block 62 and the screw rod 5 are detached, resulting in the interruption of the transmission connection between the first operating tube 4, the transmission member 63, the pressing block 62 and the screw rod 5. Then, the first operating handle is moved downward to drive the spin pressing seat 61, the insulating inner tube 8, the screw rod 5, the connecting shaft 7 and the crimping assembly 2 to move away from the hook member 1, so as to open the hook 11 of the hook member 1, so as to facilitate the wire to detach from the hook member 1.
