[0047] Please see Figures 1 to 5 This embodiment provides a connection structure for an emergency quick-connect rod for medium-voltage lines, including: a rod body 1, a first cable connector 2, a second cable connector 3, and a mounting base 4;
[0048] The rod body 1 has a receiving groove 11;
[0049] The first cable connector 2 includes a first conductive part 22, a second conductive part 23 and a first insulating sleeve 21. The first conductive part 22 is disposed in the receiving groove 11. The second conductive part 23 is electrically connected to the first conductive part 22 and is located outside the receiving groove 11. The first insulating sleeve 21 is sleeved on the second conductive part 23 and has a connection hole 211 that exposes the second conductive part 23.
[0050] The second cable connector 3 includes a third conductive part 32, a fourth conductive part 33, and a second insulating sleeve 31. The third conductive part 32 is disposed in the receiving groove 11 and is electrically connected to the first conductive part 22. The fourth conductive part 33 is electrically connected to the third conductive part 32 and is located outside the receiving groove 11. The second insulating sleeve 31 is sleeved on the fourth conductive part 33.
[0051] Mounting base 4 includes a support 41 and a spring 42. The support 41 is M-shaped and includes a first end plate 411 and a second end plate 412 that are perpendicular to each other. The first end plate 411 is detachably connected to the end of the rod 1 away from the receiving groove 11. The second end plate 412 of the support 41 is provided with a hole 46. One end of the spring 42 is located on the first end plate 411 and the other end is located on the second end plate 412.
[0052] The above technical solution has the following beneficial effects:
[0053] The structural design of the M-shaped support 41 enhances mechanical strength. The spring 42 effectively absorbs impact loads when subjected to external forces such as wind and cable tension, playing a buffering and shock-absorbing role, reducing the risk of equipment damage, and improving operational safety.
[0054] Please see Figure 2 In this embodiment, the support 41 also includes an arc-shaped plate located between the first end plate 411 and the second end plate 412. The first end plate 411, the arc-shaped plate, and the second end plate 412 are integrally formed and create an M-shape. This structure provides good spatial stability, allowing the mounting base 4 to more firmly support the quick-connect rod body and the utility pole.
[0055] Please see Figure 2 In this embodiment, the top of the first end plate 411 has an assembly block 43 with a first insertion hole 44, and the second end plate 412 has a second insertion hole 45. The two ends of the spring 42 are respectively fixed in the first insertion hole 44 and the second insertion hole 45 by hooks. The arc plate includes two arc structures 413 arranged side by side, and there is a gap between the two arc structures 413 for accommodating the spring 42. The spring 42 is inclined to the second end plate 412 and the first end plate 411. Figure 2 As shown, the first end plate 411 is located on the left side and is vertical, while the second end plate 412 is located on the right side and is horizontal. The arc-shaped structure 413 has a wavy shape and is arranged at intervals along the horizontal direction, with the spring 42 housed between them. The spring 42 is well-limited and protected, making full use of the internal space of the support 41 while ensuring strength, making the structure more compact and reasonable. The assembly block 43 is on top of the first end plate 411, with the left side of the spring 42 higher than the right side. The hook on the left side hooks into the first insertion hole 44, and the hook on the right side hooks into the second insertion hole 45, which can improve the impact resistance of the structure.
[0056] In this embodiment, the detachable connection between the first end plate 411 and the rod 1 is a bolted connection, such as... Figure 2 As shown.
[0057] Please see Figure 1 and Figure 4 In this embodiment, the connection structure further includes a live indicator accessory 8, which is electrically connected to the second conductive part 23. The live indicator accessory 8 has an equipotential liveness display function. When the quick-connect rod is connected to a live line, the indicator light illuminates, thus visually displaying whether the connecting rod is currently live. Figure 1 As shown, the live display accessory 8 is located on the side of the first insulating sleeve 21 facing the second cable connector 3 for easy viewing.
[0058] Please see Figure 1 In this embodiment, the live display accessory 8 is located between the first insulating sleeve 21 and the second insulating sleeve 31. The lower part of the first insulating sleeve 21 has a clearance groove 212 to avoid accommodating the live display accessory 8. This avoids occupying additional external space and improves the overall structural compactness.
[0059] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the first insulating sleeve 21 is sleeve-shaped, with the connecting hole 211 located at the center of the sleeve. The second conductive part 23 has an arc-shaped groove 231 for electrical connection with the power grid access line 5 to be repaired. The arc-shaped groove 231 is directly opposite the connecting hole 211, ensuring accurate alignment and improving connection stability and ease of operation. The operator passes the power grid access line 5 to be repaired through the connecting hole 211 on the first insulating sleeve 21 and inserts it into the arc-shaped groove 231 at the top of the second conductive part 23, making contact with the second conductive part 23 to complete the electrical connection. This method is convenient to use.
[0060] Please see Figures 1 to 3 In this embodiment, the first conductive part 22 and the third conductive part 32 are perpendicular to each other, and the third conductive part 32 is coaxial with the rod body 1. The second cable connector is placed horizontally as a whole, so that the cable 6 of the external emergency power supply can be hooked on the second cable connector 3 to prevent it from falling off.
[0061] Please see Figure 1 and Figure 3 In this embodiment, the end of the second insulating sleeve 31 is provided with a connecting ring 311. When the operator climbs the pole, the working space is small. After the second insulating sleeve 31 is removed from the second cable connector 3, there is no suitable space to put it. If it is thrown to the ground, it needs to be picked up and installed after the maintenance is completed, which is cumbersome. However, it is convenient for the operator to put the second insulating sleeve 31 directly through its connecting ring 311 onto the second cable connector 3, which can also improve the maintenance efficiency.
[0062] Please see Figure 3 In this embodiment, the fourth conductive part 33 is provided with a limiting part 34, which is used for the cable 6 of the external emergency power supply to be hooked and connected. Specifically, the cable 6 of the external emergency power supply is hooked and connected using a drain clamp 7, and the upper surface of the limiting part 34 has a "V" shaped structure that is adapted to the drain clamp 7.
[0063] Please see Figure 5 In this embodiment, the emergency quick-connect rod for medium-voltage lines has three connection structures, with three mounting bases 4 connected side-by-side to the utility pole. Specifically, a horizontal platform is fitted onto the utility pole, allowing workers to fix bolts onto the platform by passing them through the holes 46 in the second end plate 412 of the mounting base 4.
[0064] In this embodiment, the rod body 1 is made of high-polymer blended epoxy material, which has high voltage resistance and insulation properties, and serves to fix the first cable connector 2 and the second cable connector 3. During the manufacturing process of this medium-voltage line emergency quick-connect rod, the first cable connector 2 and the second cable connector 3 can be electrically connected first and then placed into a mold. Insulating material is then poured into the mold to fix the first conductive part 22 of the first cable connector 2 and the third conductive part 32 of the second cable connector 3 within the rod body 1, and to strengthen the conductive connection between them.
[0065] Please see Figure 5 When the first cable connector needs to be used for external connection, the worker climbs the pole and inserts the power grid access line 5 to be inspected through the connection hole 211 of the first insulating sleeve 21 and electrically connects it to the arc groove 231 of the second conductive part 23. When the second cable connector needs to be used for external connection, the worker climbs the pole and removes the second insulating sleeve 31, exposing the fourth conductive part 33 of the second cable connector 3, so that the external emergency power supply cable 6 can be connected to it. The second cable connector 3 provided by this medium-voltage line emergency quick-connect rod can be repeatedly attached to the external emergency power supply cable 6. When not in use, the second insulating sleeve 31 can be fitted onto the second cable connector 3. This quick-connect rod is easy to install, simple in structure, low in manufacturing cost, and easy to promote.
[0066] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
