This technology, applied to grounding wires, can effectively solve the safety hazards caused by time differences; by using a grounding wire with voltage detection function, an additional safety guarantee is added to on-site construction; at the same time, it reduces the number of tools carried in actual work, further improving work efficiency. However, this technology still has the following problems.

[0004] In power distribution systems, grounding wires are crucial for safety. Voltage testing can determine whether a grounding fault exists. However, since both the grounding wire and the voltage testing point are in conductive contact, in real-world scenarios, due to air humidity and external environmental factors, a corrosive rust layer can easily form at the contact point between the voltage testing point and the grounding wire. The appearance of this rust layer can cause poor contact during voltage testing, thus interfering with normal voltage testing operations. This poor contact problem makes it difficult to accurately obtain grounding wire status information during the voltage testing process, significantly reducing the accuracy of grounding fault voltage testing.

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention utilizes the synergistic action of vertical and horizontal friction components. The vertical friction component drives multiple friction ends to rotate in both directions for vertical reciprocating friction, while the horizontal friction component drives the friction ends to move laterally for friction. Simultaneously, as the automatic flow guiding component moves the flow guiding tube upward, it precisely delivers conductive lubricant to the friction contact area. This achieves integrated treatment of friction, rust removal, and conductive lubricant filling at all-round friction points and tooth terminals. It removes rust and fills the contact area with conductive lubricant, providing corrosion and rust resistance while ensuring full conductivity. This effectively solves the problem of poor contact caused by rust and significantly improves the accuracy of grounding fault detection.

[0017] 2. The automatic flow guiding component of this invention drives the protrusion to lift the sealing block through the axial movement of the flow guiding pipe, thereby automatically opening and closing the outlet of the container. Under the action of gravity, the conductive lubricant is accurately delivered through the flow guiding pipe to the intricately distributed flow channel network inside the friction end. Through the docking hole, main hole and inclined side hole, it is evenly applied to each contact surface between the tooth end and the friction end. It not only uses the flushing of the conductive lubricant to help remove rust residue, but also forms a durable conductive protective film on the contact surface. It has the dual effect of inhibiting rust layer regeneration and optimizing current conduction, which greatly improves the accuracy of ground fault detection. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention will be further described in detail below with reference to the figures.

[0031] Example 1: like Figure 1 - Figure 7The illustrated grounding wire device for voltage testing includes a grounding wire 1, with toothed terminals 2 fixed to the outer wall of the grounding wire 1. Multiple friction terminals 3 are slidably disposed on the outside of the toothed terminals 2. A groove seat 23 is fixed to the outer side of the grounding wire 1, with the upper part of the groove seat 23 located on both sides of the toothed terminals 2. A guide tube 4 is fixedly connected to the top of the friction terminals 3, and an automatic guide assembly is provided at the top of the guide tube 4. A vertical friction assembly is installed outside the guide tube 4. A sleeve 8 is installed on the outer wall of the guide tube 4, away from the friction terminals 3. A horizontal friction assembly is also included. The components are arranged on one side of the sleeve plate 8; the voltage detection unit is arranged on one side of the toothed terminal 2; the vertical friction assembly drives multiple friction ends 3 to rotate forward and then reverse to reset, so that the friction ends 3 and the outer wall of the toothed terminal 2 perform vertical reciprocating friction to remove the rust layer. At the same time, the vertical friction assembly drives the guide tube 4 to move upward, driving the automatic guide assembly to deliver conductive lubricant to the friction contact area between the toothed terminal 2 and the friction ends 3. The horizontal friction assembly is used to drive multiple friction ends 3 to make horizontal contact friction with the toothed terminal 2. The voltage detection unit is used to perform ground fault voltage detection operation on the toothed terminal 2.

[0032] The implementation principle of this embodiment is as follows: In the power distribution system, when multiple friction ends 3 come into contact with toothed terminals 2, the vertical friction assembly drives the multiple friction ends 3 to rotate in a circular arc path. In this way, the multiple friction ends 3 and toothed terminals 2 move and rub vertically in a forward rotation. Then, the vertical friction assembly reverses and resets, so that the multiple friction ends 3 and toothed terminals 2 can continue to rub against each other, and the friction ends 3 and the outer wall of toothed terminals 2 can rub vertically back and forth to remove the rust layer.

[0033] As the vertical friction component moves the guide tube 4 upward, the guide tube 4 will drive the automatic guide component to guide the conductive lubricant from the guide tube 4 into the friction end 3. This will distribute the conductive lubricant to multiple contact points between the friction end 3 and the toothed end 2. This not only removes the rust layer at the contact points between the toothed end 2 and the friction end 3, but also ensures that the contact points between the toothed end 2 and the friction end 3 are filled with conductive lubricant, thus providing both corrosion and rust prevention and enabling fully conductive operation. The transverse friction assembly provides a transverse force to the toothed terminal 2, causing the friction end 3 to reciprocate vertically against the outer wall of the toothed terminal 2 to remove the rust layer. At the same time, it also allows the conductive lubricant to move laterally and lubricate the surface. After treatment, power is supplied to the grounding hard wire 1, which generates current. The grounding hard wire 1 conducts the current to the toothed terminal 2, and the toothed terminal 2 conducts the current to multiple friction ends 3. Not only is the rust layer removed between the toothed terminal 2 and the friction ends 3, but the conductive lubricant can also fully conduct electricity, ensuring that the toothed terminal 2 conducts the current to the friction ends 3. The friction ends 3 conduct the current to the voltage detection unit, which detects whether there is current. If there is current, the grounding hard wire 1 is grounded normally. If there is no current in the grounding hard wire 1, the grounding hard wire 1 is disconnected, and a grounding fault occurs. This realizes the current test operation for grounding faults.

[0034] Example 2: like Figure 3 - Figure 4 As shown, the vertical friction assembly includes: a pressure ring 5, installed on the outer wall of the guide tube 4, with both the guide tube 4 and the friction end 3 fixedly connected to the pressure ring 5; multiple arc-shaped sleeves 7, all fixed on the inner wall of the sleeve plate 8, with a first spring 6 installed between the arc-shaped sleeves 7 and the pressure ring 5, the first spring 6 providing elastic force to the pressure ring 5, and the sleeve plate 8 and the arc-shaped sleeves 7 slidably connected to the guide tube 4; and a guide rod 9, installed outside the first spring 6, fixedly connected to the friction end 3, and used for guiding and sliding along the inner wall of the sleeve plate 8. The multiple arc-shaped sleeves 7 are arranged in an arc distribution, and each arc-shaped sleeve 7 is aligned with one of the multiple friction ends 3.

[0035] like Figure 3 - Figure 9 As shown, the transverse friction assembly includes: a side block 19, fixed to one side of the sleeve plate 8; a pressure post 20 fixed to one side of the side block 19; a slip ring 21 slidably connected to the outer wall of the pressure post 20; a second spring 22 fixed between the slip ring 21 and the side block 19, which provides elastic force to the side block 19; an arc-shaped block 24 fixed to one end of the pressure post 20, which is slidably connected to the groove seat 23, which is fixedly connected to the grounding hard wire 1; a stepped block 25 fixed to one side of the slip ring 21, which is slidably connected to the groove seat 23; and the slip ring 21 is slidably connected to the groove seat 23. The arc-shaped block 24 is used for transverse movement or vertical arc sliding along the interior of the groove seat 23. A gripping rod 26 is fixed to the top of the side block 19 for hand gripping.

[0036] The vertical friction principle of this embodiment is as follows: When the hand grips the outer wall of the gripping rod 26, rotating the gripping rod 26 in the forward direction causes the side block 19 to rotate in the forward direction. The side block 19 then causes the pressure column 20 to rotate in the forward direction. The pressure column 20 causes the arc-shaped block 24 to rotate in the forward direction on the inner wall of the slot seat 23. Simultaneously, the pressure column 20 causes the slip ring 21 to rotate in the forward direction, which in turn causes the stepped block 25 to rotate in the forward direction. The stepped block 25 rotates in the forward direction inside the slot seat 23. The slot seat 23 is primarily fixed by bolt insertion and locking, thus achieving a fixed operation for the slot seat 23. The slot seat 23 also provides a fixed operation for the grounding hard wire 1. In this way, the side block 19 causes the sleeve plate 8 to rotate in the forward direction, the sleeve plate 8 causes multiple arc-shaped sleeves 7 to rotate in the forward direction, and the arc-shaped sleeves 7 drive the flow guide. The tube 4 rotates in the forward direction, and the guide tube 4 causes the pressure ring 5 to rotate in the forward direction. The pressure ring 5 drives the friction end 3 to rotate in the forward direction. The friction end 3 is pressed against the original tooth groove of the toothed end 2. Thus, the friction end 3 moves upward under force, and the friction end 3 drives the pressure ring 5 to move upward. The pressure ring 5 drives the guide tube 4 to move upward, and the guide tube 4 drives the first spring 6 to move upward. The first spring 6 is compressed on the arc sleeve 7, and the sleeve plate 8 supports multiple arc sleeves 7 to ensure that the friction end 3 moves into another tooth groove on the toothed end 2 after being compressed. When the toothed end 2 moves into another tooth groove, the first spring 6 can be supported by the arc sleeve 7. Under the action of the rebound force of the first spring 6, the pressure ring 5 moves downward. The pressure ring 5 drives the friction end 3 to insert into another tooth groove to achieve friction treatment again.

[0037] The gripping rod 26 drives the side block 19 to reverse, the side block 19 drives the sleeve plate 8 to rotate in the opposite direction, the sleeve plate 8 drives the arc sleeve 7 to rotate in the opposite direction, the arc sleeve 7 causes the guide tube 4 to rotate in the opposite direction, the guide tube 4 drives the pressure ring 5 to rotate in the opposite direction, the pressure ring 5 causes the friction end 3 to rotate in the opposite direction, the friction end 3 drives the pressure ring 5 to move upward and squeeze, the pressure ring 5 squeezes the first spring 6, the first spring 6 is compressed, so the friction end 3 moves from another tooth groove on the toothed end 2 to the origin tooth groove to reset, and the rebound force of the first spring 6 can make the pressure ring 5 drive the friction end 3 to continue to insert into the origin tooth groove. Multiple friction ends 3 and toothed end 2 perform vertical reciprocating friction to remove the rust layer.

[0038] The principle of lateral friction implementation in this embodiment is as follows: By applying a lateral leftward displacement force to the gripping rod 26, the side block 19 drives the pressure column 20 to move laterally to the left. The pressure column 20 moves laterally to the left along the inner wall of the slip ring 21, and the side block 19 compresses the second spring 22. The second spring 22 is compressed on the slip ring 21. At the same time, the arc-shaped block 24 moves laterally to the left along the interior of the slot seat 23, and the stepped block 25 can be positioned on the inner wall of the slot seat 23. The stepped block 25 supports the slip ring 21. The side block 19 drives the sleeve plate 8 to move laterally to the left. The sleeve plate 8 drives the guide tube 4 to move laterally to the left. The guide tube 4 drives the pressure ring 5 to move laterally to the left. 5. The friction end 3 moves laterally to the left, and multiple friction ends 3 come into contact with the toothed end 2 laterally to the left. No longer applying force to the grip rod 26, the second spring 22 provides a rebound force to the side block 19 to move laterally to the right. The side block 19 moves the sleeve plate 8 laterally to the right, the sleeve plate 8 moves multiple guide tubes 4 laterally to the right, the guide tubes 4 move the pressure ring 5 laterally to the right, and the pressure ring 5 moves the friction end 3 laterally to the right. In this way, multiple friction ends 3 can make lateral contact with the toothed end 2, and with the vibration effect of the spring, the rust layer at the contact point between the toothed end 2 and the friction end 3 is removed.

[0039] Example 3: like Figure 3 - Figure 6 As shown, the automatic flow guiding assembly includes: a protrusion 11 fixed to the top of the flow guiding pipe 4, a sealing block 10 fixed to the top of the flow guiding pipe 4, and a receiving box 12 slidably mounted on the outer wall of the protrusion 11 for holding conductive lubricating fluid; a support sleeve 13 fixed between the sleeve plate 8 and the receiving box 12, and a silicone sleeve 14 fixed to the inner wall of the support sleeve 13 for guiding the flow guiding pipe 4 to slide; and a docking hole 15 opened on the inner wall of the friction end 3, with a main hole 16 opened at the bottom of the inner wall of the docking hole 15, and connected oblique side holes 17 opened on both sides of the inner wall of the main hole 16, for the conductive lubricating fluid to be diverted into the oblique side holes 17 and the main hole 16. The center point of the protrusion 11 is concentric with the center point of the sealing block 10, and the cross-sectional area of ​​the top of the protrusion 11 is smaller than the cross-sectional area of ​​its bottom. The oblique side holes 17 are set at an angle, and two adjacent oblique side holes 17 are symmetrically arranged about the middle of the friction end 3. The top of the housing 12 is threadedly connected to a threaded cap 18.

[0040] The implementation principle of this embodiment is as follows: Initially, by rotating the threaded cap 18, the threaded cap 18 separates from the housing 12, allowing conductive lubricant to be poured into the housing 12. Then, the threaded cap 18 is reversed, closing and sealing with the housing 12. When the guide tube 4 moves upward, it is guided upward along the inner wall of the silicone sleeve 14. The sleeve plate 8 supports the support sleeve 13, which in turn supports the silicone sleeve 14. The silicone sleeve 14 guides the outer wall of the guide tube 4, ensuring that the guide tube 4 drives the protrusion 11 upward. Since the cross-sectional area of ​​the top of the protrusion 11 is larger than that of its bottom, the protrusion 11 will squeeze the sealing block 10 upward. The sealing block 10 no longer forms a seal with the bottom of the inner wall of the housing 12, thus automatically opening the bottom of the housing 12. At the opening of the part, the conductive lubricant inside the housing 12 is guided by gravity to the guide tube 4, and then poured into the friction end 3 through the guide tube 4. The conductive lubricant is then guided to the mating hole 15, and then to the main hole 16. The main hole 16 can guide the conductive lubricant to the bottom contact area between the toothed end 2 and the friction end 3. The oblique side hole 17 can guide the conductive lubricant to the side contact area between the toothed end 2 and the friction end 3. During the vertical friction between the toothed end 2 and the friction end 3, the conductive lubricant can be automatically distributed to the friction contact area between the toothed end 2 and the friction end 3, realizing multi-point conductive lubrication treatment. It can not only remove rust, but also fully lubricate to prevent rusting, and also achieve full conductivity to avoid the problem of poor contact.

[0041] Example 4: like Figure 10 As shown, the voltage testing unit includes: a voltage testing wire 27, which is installed on one side of the friction end 3. Multiple friction ends 3 are electrically connected to the voltage testing wire 27. A current detector 28 is installed on the outer wall of the voltage testing wire 27. The current detector 28 is used to detect the current of the voltage testing wire 27. An alarm light 29 is installed on one side of the current detector 28. The alarm light 29 is used for ground fault alarm.

[0042] The implementation principle of this embodiment is as follows: When testing for voltage on the grounding hard wire 1, the grounding fault of the grounding hard wire 1 is detected. The grounding hard wire 1 is energized, and the grounding hard wire 1 conducts the current to the toothed terminal 2. There is no rust layer between the toothed terminal 2 and the friction end 3, and the space between the toothed terminal 2 and the friction end 3 is filled with conductive lubricant, thus conducting electricity to the friction end 3. The friction end 3 conducts electricity to the testing wire 27. After the testing wire 27 is collected, the current detector 28 is used to detect whether there is current. If the current detector 28 detects current, the grounding hard wire 1 is grounded normally. If the current detector 28 does not detect current, there is a grounding failure. The current detector 28 immediately turns on the alarm light 29 to alert the maintenance personnel, thus realizing the voltage testing operation for the grounding fault of the grounding hard wire 1.
