[0002] In the operation and maintenance of power systems, grounding is a crucial step in ensuring the safety of personnel and the stability of equipment. Traditional grounding devices present several inconveniences during operation, such as slow grounding speed, inability to meet the needs of rapid response, unstable wire-end connections prone to poor contact, and inconvenient insertion and removal of grounding wires, increasing operational complexity and time costs. Furthermore, the structural design of some grounding devices is not reasonable, leading to certain safety hazards during use. Therefore, it is essential to provide a fast grounding and quick-connect grounding wire device with a flared end that is simple and reasonable in structure, quick and convenient to use, and enables rapid grounding and quick-connection functions, thereby improving work efficiency and safety.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings. Example

[0031] like Figure 1-8 As shown, a quick-grounding and flared-end quick-plug grounding wire device includes an insulating operating rod 1 and a clamp 4. The clamp 4 is located on the upper part of the insulating operating rod 1 and is used to clamp the end of the conductor 5 to achieve connection with the line. A connecting conductor cone 2 for conducting current is sleeved on the top of the insulating operating rod 1. The clamp 4 is installed on the upper end of the connecting conductor cone 2. An equalizing ring 3 for uniform electric field distribution is set between the clamp 4 and the connecting conductor cone 2 near the clamp 4. A telescopic insulating extension rod 6 is detachably connected to the lower part of the insulating operating rod 1. A plug-in insulating rod 7 is detachably inserted into the telescopic insulating extension rod 6. The plug-in insulating rod 7 is plugged into and connected to the grounding box 8 to introduce current into the ground.

[0032] The insulating operating rod 1 includes a rod body 11. A conductive rod 12 is arranged inside the rod body 11 along its central axis. A conductive plug 14 is installed at the top of the conductive rod 12. A rod sleeve 13 is sleeved on the outside of the conductive plug 14. The rod sleeve 13 is connected to the upper end of the rod body 11 by an interference fit. A locking pin 15 is provided at the front of the end of the conductive plug 14 that extends out of the rod sleeve 13 and into the connecting wire cone 2.

[0033] In this embodiment, the rod sleeve is T-shaped, with its upper diameter smaller than its lower diameter, and the lower diameter of the rod sleeve being slightly larger than the upper diameter of the rod body, allowing the rod sleeve to be reliably and stably fitted onto the outside of the rod body. The conductive plug is installed at the top of the conductive rod, and it is also T-shaped. Its larger diameter lower end is located inside the rod body at the junction of the rod sleeve and the rod body, while its smaller diameter upper end is located at the top of the rod sleeve and extends out of the rod sleeve. A locking pin is installed on the free end of the conductive plug extending out of the rod sleeve. The locking pin is perpendicular to the conductive plug, and the locking pin can be detachably engaged with the connecting wire cone to achieve a detachable connection between the insulating operating rod and the connecting wire cone.

[0034] The connecting wire cone 2 includes a flared skirt seat 21 with the opening side located on one side of the conductive plug 14. The upper part of the flared skirt seat 21 is a vertical tube 22 arranged longitudinally. The upper surface of the vertical tube 22 is fixedly connected to the wire clamp 4. The lower part of the vertical tube 22 is provided with a plug sleeve 23 and the upper part is provided with a spring seat 24. The plug sleeve 23 and the spring seat 24 are connected by a first spring 25.

[0035] In this embodiment, the flared skirt base opens downwards, and its center is a hollow structure. Specifically, the center of the flared skirt base has a through hole for the conductive plug to pass through, and a limit pin hole is formed on the downward-facing inner side of the flared skirt base. Figure 4 As shown, the limiting pin hole mates with the locking pin rod, and the limiting pin hole communicates with the through hole in the center of the flared skirt seat; blind holes are provided on the upper surface of the plug sleeve and the lower surface of the spring seat for installing the upper and lower ends of the first spring; a blind hole is provided on the lower surface of the plug sleeve to mate with the conductive plug; its working process is as follows: After securing the wire with the clamp, align the conductive plug of the upper end of the insulating rod extending from the rod sleeve with the flared skirt of the connecting wire cone, and then insert it into the through hole inside the flared skirt. Figure 4 As shown, rotating the operating insulating rod aligns the locking pin with the limiting pin hole, then drives the conductive plug upward, pushing the plug-in sleeve upward so that the conductive plug and locking pin enter the vertical pipe as a whole. Then, rotating the operating insulating rod causes the locking pin to misalign with the limiting pin hole. Under the action of the first spring, the plug-in sleeve is pushed downward, causing the conductive plug and locking pin to move. At this time, the locking pin can no longer pass through the limiting pin hole, finally realizing the live connection operation between the operating insulating rod and the connecting wire cone. The first spring driving the plug-in sleeve to move downward not only enables the plug-in sleeve to reliably connect with the conductive plug, but also allows the conductive plug to be reliably fixed inside the vertical pipe through the cooperation between the locking pin and the through hole in the flared skirt seat, realizing the reliable connection between the operating insulating rod and the connecting wire cone.

[0036] The wire clamp 4 includes a base plate 41 fixedly connected to the upper surface of the vertical tube 22. A T-shaped rod 42 is fixed on the upper side of the base plate 41. The upper left side of the T-shaped rod 42 is an arc-shaped downward-curved upper clamping plate 43, and the right side is a screw hole 45 with a threaded through hole. Several clamping teeth 44 are evenly spaced on the arc-shaped surface inside the upper clamping plate 43.

[0037] A movable plate 46 is provided at the lower end of the screw hole portion 45, and the movable plate 46 and the screw hole portion 45 are connected by an adjusting screw 47. A lower retainer 48 is fixedly connected to the left side of the movable plate 46. A set of V-shaped retainers 49 are provided at intervals on the upper surface of the lower retainer 48. A sliding opening 401 for longitudinal sliding cooperation with the T-shaped rod 42 is provided on the side of the lower retainer 48 near the movable plate 46.

[0038] In this embodiment, the working process of the wire clamp is as follows: by operating the insulating rod, the upper clamping plate is placed on the upper end of the wire, and the inner arc surface of the upper clamping plate contacts the outer surface of the wire. Then, the lower clamping seat is moved upward by the adjusting screw, and the adjusting screw is tightened. Since the adjusting screw is threadedly engaged with the moving plate, the adjusting screw drives the moving plate to move upward. During the upward movement of the moving plate, the lower clamping seat will move synchronously. Since the lower clamping seat is engaged with the T-shaped rod through the avoidance fitting sliding port, the T-shaped rod will not interfere with the movement of the lower clamping seat. As the lower clamping seat moves upward, the space between the lower clamping seat and the upper clamping plate gradually decreases. Finally, the wire is clamped by the cooperation of the lower clamping seat and the upper clamping plate, and the clamping force is further improved by the clamping teeth inside the upper clamping plate, so that the clamping effect of the wire is better.

[0039] This utility model is a quick grounding and flared-end quick-connect grounding wire device. In use, this utility model utilizes an adjustable wire clamp 4 structure, which can accommodate different specifications of conductors 5 while quickly and reliably achieving conductor 5 connection operations. This allows for rapid completion of the grounding operation, significantly shortening operation time and improving the efficiency of power operation and maintenance. The wire clamp 4 of this utility model utilizes the adjustable engagement of the upper clamping plate 43 and the lower clamping seat 48 to better adapt to the shape of the wire end. The clamping teeth 44 inside the upper clamping plate 43 increase friction, ensuring tight contact with the wire end, reducing contact resistance, and improving the reliability of the electrical connection. The equalizing ring 3 of this utility model effectively uniformizes the electric field distribution and reduces... The risk of partial discharge makes the overall operation safer and more reliable; the insulated operating rod 1 of this utility model ensures the safety of the operator, and the design of the entire device improves the safety of power operation and maintenance work; the insulated operating rod 1 and the telescopic insulated extension rod 6 of this utility model adopt a plug-in connection and threaded locking mechanism to realize the quick insertion and removal of the grounding wire, which is simple and convenient to operate, reducing the complexity of operation and labor intensity; this utility model has the advantages of being fast, safe, reliable, and easy to operate, and can effectively improve the efficiency and safety of power operation and maintenance work; this utility model has the advantages of simple and reasonable structure, quick and convenient use, realization of quick grounding and quick insertion functions, and improvement of work efficiency and safety. Example

[0040] like Figure 1-8 As shown, a quick-grounding and flared-end quick-plug grounding wire device includes an insulating operating rod 1 and a clamp 4. The clamp 4 is located on the upper part of the insulating operating rod 1 and is used to clamp the end of the conductor 5 to achieve connection with the line. A connecting conductor cone 2 for conducting current is sleeved on the top of the insulating operating rod 1. The clamp 4 is installed on the upper end of the connecting conductor cone 2. An equalizing ring 3 for uniform electric field distribution is set between the clamp 4 and the connecting conductor cone 2 near the clamp 4. A telescopic insulating extension rod 6 is detachably connected to the lower part of the insulating operating rod 1. A plug-in insulating rod 7 is detachably inserted into the telescopic insulating extension rod 6. The plug-in insulating rod 7 is plugged into and connected to the grounding box 8 to introduce current into the ground.

[0041] The telescopic insulating extension rod 6 includes a telescopic rod 61, and a conductive extension rod 62 is arranged inside the telescopic rod 61 along its central axis. A cover 63 is fitted onto the lower end of the telescopic insulating extension rod 6.

[0042] In this embodiment, the telescopic rod can adopt a two-section or multi-section telescopic structure. The following description uses a two-section telescopic rod as an example. When the telescopic rod is in the retracted state, the lower ends of the two sections coincide, meaning they are on the same plane. The lower end of the conductive extension rod located inside the telescopic rod slightly protrudes from the lower end of the telescopic rod. This facilitates the connection of the conductive extension rod to the plug-in insulating rod and grounding box using a grounding wire. Furthermore, a cap is fitted onto the lower end of the telescopic rod, protecting the lower end of the conductive extension rod in both the non-working and working states, greatly improving safety. A set of vertical rods is symmetrically arranged along the lower circumference of the cover, which can fix and protect the plug-in insulating rod inserted inside. The process is as follows: when the grounding purpose can be achieved without unfolding the telescopic insulating extension rod, that is, without using a grounding wire to connect the conductive extension rod and the plug-in insulating rod, the telescopic insulating rod is simply in the retracted state. Then, the conductive seat at the upper end of the plug-in insulating rod is inserted into the cover, and the conductive seat is plugged into the lower end of the conductive extension rod. Then, the plug-in insulating rod is plugged into the grounding box to complete the grounding operation. This connection method is only one way of using this utility model.

[0043] The upper end of the telescopic insulating extension rod 6 is provided with a second quick connector 10, which is threadedly and tightly connected to the first quick connector 9 installed at the lower end of the insulating operating rod 1 to ensure the stability of current transmission.

[0044] The first quick connector 9 includes a connecting tube 91 sleeved and installed at the lower end of the insulating operating rod 1. The lower end of the connecting tube 91 is provided with an external thread 92. The lower end of the connecting tube 91 is provided with a limiting sleeve 93. A set of limiting claws 94 are symmetrically arranged on the outer periphery of the lower edge of the limiting sleeve 93. A connecting female head 95 installed at the lower end of the conductive rod 12 is provided inside the limiting sleeve 93. The second quick connector 10 is externally sleeved and installed with a threaded tube that mates with the external thread 92 at the lower end of the connecting tube 91. 103, the threaded tube 103 is provided with an outer protective tube 102 inside, the upper end of the outer protective tube 102 is a mating sleeve 104, the mating sleeve 104 is symmetrically provided with a set of mating slots 105 that are inserted and cooperate with the limiting claws 94 on the circumferential surface, the outer protective tube 102 is provided with a connecting male head 101 installed on the upper end of the conductive extension rod 62, the connecting male head 101 is inserted and cooperated with the connecting female head 95, and the threaded connection between the connecting tube 91 and the threaded tube 103 is used to achieve a tight connection.

[0045] In this embodiment, the outer sheath is sleeved and installed on the upper end of the insulating rod, while the threaded sleeve is installed on the outer sheath. For ease of use, the threaded tube can be configured to rotate with the outer sheath. For example, the threaded tube has an annular groove inside, and the outer sheath has an annular convex ring on the outside that rotates with the annular groove. Of course, other methods can also be used, which will not be elaborated here. The upper end of the connecting female is fixedly connected to the conductive rod, and its lower end is composed of multiple elastic insertion receiving plates. The multiple elastic insertion receiving plates are evenly spaced around the lower circumference of the connecting female, and the multiple elastic insertion receiving plates as a whole form a conical structure. That is, the conical structure formed by the multiple elastic insertion receiving plates gradually tapers downward from the upper end fixed to the connecting female, so that the lower opening diameter is smaller than the upper diameter. The limiting sleeve is installed outside the connecting female, and the lower ends of the multiple elastic insertion receiving plates extend out of the limiting sleeve. A set of limiting claws of the limiting sleeve are inserted and engaged with the mating slot hole, and the external thread engages with the threaded tube. The working process of the first quick connector and the second quick connector is as follows: When connecting the telescopic insulating extension rod and the operating insulating rod, simply align the male and female connectors on the telescopic insulating extension rod, insert the male connector into the elastic receiving port plate of the female connector, and then rotate the telescopic insulating extension rod to align the mating slot with the limiting claw, allowing them to engage. As the engagement continues, the male connector will extend further into the female connector until the external thread at the lower end of the connecting tube contacts the threaded tube. Then, rotate the threaded tube to connect with the external thread at the lower end of the connecting tube, simultaneously ensuring the male connector is fully inserted into the female connector, creating a tight connection. This not only connects the telescopic insulating extension rod and the operating insulating rod, enabling their extension operation and facilitating the extension of the operating insulating rod to meet work requirements, but also ensures a reliable connection between the conductive rod and the conductive extension rod, completing the grounding operation.

[0046] This utility model is a quick grounding and flared-end quick-connect grounding wire device. In use, this utility model utilizes an adjustable clamp 4 structure, which can accommodate different specifications of conductors 5 while quickly and reliably achieving conductor 5 connection operations. This allows for rapid completion of grounding operations, significantly shortening operation time and improving the efficiency of power operation and maintenance. The insulated operating rod 1 ensures the safety of operators, and the overall design of the device improves the safety of power operation and maintenance. The insulated operating rod 1 and the telescopic insulated extension rod 6 are connected by a plug-in connection and threaded locking mechanism, enabling quick insertion and removal of the grounding wire. Operation is simple and convenient, reducing operational complexity and labor intensity.

This utility model has the advantages of simple and reasonable structure, quick and convenient use, achieving rapid grounding and quick-connect functions, and improving work efficiency and safety. Example

[0047] like Figure 1-8 As shown, a quick-grounding and flared-end quick-plug grounding wire device includes an insulating operating rod 1 and a clamp 4. The clamp 4 is located on the upper part of the insulating operating rod 1 and is used to clamp the end of the conductor 5 to achieve connection with the line. A connecting conductor cone 2 for conducting current is sleeved on the top of the insulating operating rod 1. The clamp 4 is installed on the upper end of the connecting conductor cone 2. An equalizing ring 3 for uniform electric field distribution is set between the clamp 4 and the connecting conductor cone 2 near the clamp 4. A telescopic insulating extension rod 6 is detachably connected to the lower part of the insulating operating rod 1. A plug-in insulating rod 7 is detachably inserted into the telescopic insulating extension rod 6. The plug-in insulating rod 7 is plugged into and connected to the grounding box 8 to introduce current into the ground.

[0048] The plug-in insulating rod 7 includes an outer tube 71, with a conductive seat 72 sleeved at the upper end and a lower tube body 73 sleeved at the lower end. The lower end of the lower tube body 73 is provided with a plug-in seat 74 that is plugged into and connected to the grounding box 8. A movable seat 75 with a "T" structure is provided above the plug-in seat 74. The movable seat 75 and the plug-in seat 74 are connected by a second spring 76.

[0049] In this embodiment, there are multiple ways to connect the plug-in insulating rod and the telescopic insulating extension rod. One way is to connect the conductive extension rod and the conductive base inside the telescopic insulating extension rod using a grounding wire. Alternatively, the conductive base can be plugged into the conductive extension rod to complete the connection. The conductive base is connected to the movable base internally via a connecting wire or conductor structure located inside the outer tube (see attached diagram). Figure 6-7 (The connecting lines or conductor structures are not clearly shown in the drawing). Then, connect the plug-in insulating rod to the grounding box to complete the grounding operation. The lower tube has a T-shaped stepped groove at the top, with the larger diameter at the top and the smaller diameter at the bottom. The lower tube also has a downward-opening flared structure with a through hole in the center for the grounding post to pass through. A locking pin hole is located on the downward-opening inner side of the flared structure. Figure 8 As shown, the locking pin hole mates with the connecting pin rod, and the locking pin hole is connected to the through hole in the center of the flared structure; the plug-in seat is located inside the lower tube body and above the opening of the flared structure. The movable seat is T-shaped, with a smaller diameter at the top and a larger diameter at the bottom. The lower part of the movable seat is located inside the lower end of the outer tube and is flush with its lower end. The lower end of the outer tube is located inside the upper part of the lower tube body; blind holes are provided on the upper surface of the plug-in seat and the lower surface of the movable seat for installing the upper and lower ends of the second spring; a blind hole is provided on the lower surface of the plug-in seat to mate with the grounding post.

[0050] The grounding box 8 includes an open box 81, and an opening and closing cover 82 for closing the open box 81 is movably installed on the side of the open box 81. The open box 81 is provided with a grounding post 83 with a "T" structure inside. A pin 84 is provided in front of the grounding post 83. The grounding post 83 is plugged into the socket 74.

[0051] In this embodiment, the working process of inserting the insulating rod and the grounding box is as follows: By manipulating the plug-in insulating rod, align the center through hole of the flared structure at its lower end with the grounding post inside the grounding box, and then move the plug-in insulating rod downwards to insert the grounding post into the through hole of the flared structure, as shown. Figure 8 As shown, rotating the control plug-in insulating rod aligns the pin with the locking pin hole. Then, moving the plug-in insulating rod downwards causes the grounding post to move upwards, lifting the plug-in seat. This allows the pin to pass through the locking pin hole and enter the lower tube. Rotating the plug-in insulating rod then disaligns the pin with the locking pin hole. Under the action of the second spring, the plug-in seat is pushed downwards, causing the grounding post and pin to move. At this point, the pin can no longer pass through the locking pin hole, ultimately achieving the live connection operation between the plug-in insulating rod and the grounding box. The second spring moving the plug-in seat downwards not only ensures a reliable connection between the plug-in seat and the grounding post but also, through the cooperation between the pin and the through hole in the flared structure, allows the grounding post to be reliably fixed inside the lower tube, achieving a reliable connection between the plug-in insulating rod and the grounding box.

[0052] This utility model is a quick grounding and flared-end quick-connect grounding wire device. In use, this utility model utilizes an adjustable clamp 4 structure, which can be adapted to different specifications of conductors 5 while quickly and reliably achieving conductor 5 connection operations. This allows for rapid completion of the grounding operation, greatly shortening the operation time and improving the efficiency of power operation and maintenance. The equalizing ring 3 of this utility model effectively uniformizes the electric field distribution, reducing the risk of partial discharge and making the overall operation safer and more reliable.
