Description

Technical Field

[0001] This invention relates to the field of power distribution switch interface technology for power grid equipment, and more particularly to a fast interface device for a pole-mounted switch controller. Background Technology

[0002] With the continuous growth of society's electricity demand and the increasing requirements for power quality, existing models are increasingly unable to meet users' demands for power security and reliability. Distribution network automation can significantly improve power supply reliability, and a core function of distribution network automation is feeder automation. Feeder automation based on FTU (Distribution Unit) remote terminals represents the current development direction of distribution network feeder automation technology. As the control terminal for feeder automation, the product quality of the automation controller device is undoubtedly one of the crucial supports for feeder automation technology to achieve significant economic and social benefits.

[0003] Automated control devices typically operate on overhead power lines or pole-mounted switches, communicating with workstations in real-time via general wireless packet services. The operating environment is harsh, and maintenance is difficult. If hardware problems arise, the cycle from equipment replacement to return to operation is lengthy. Therefore, demanding high-specification product quality from controller devices is undoubtedly a crucial link in the entire operating system chain. For controller factory testing, achieving efficient, rigorous, and accurate testing is the primary step and a vital guarantee for stable controller operation. Developing a rapid interface device for pole-mounted switch controllers is of significant reference value in ensuring testing quality and saving testing time.

[0004] Existing FTUs (Function Switch Monitoring Terminals) have different interfaces due to different manufacturers, requiring separate wiring for each test and troubleshooting. This is complex, error-prone, prolongs testing time, and reduces work efficiency. Furthermore, when multiple FTU interfaces need to be integrated, installation space limitations can lead to difficulties in plugging in the FTUs, making it impossible to adjust the device connection status and hindering flexible plug-in use.

[0005] Therefore, there is an urgent need to design a fast interface device for the pole-mounted switch controller to solve the above technical problems. Summary of the Invention

[0040] Example 1

[0041] like Figures 1-3 As shown, this embodiment provides a quick interface device for a pole-mounted switch controller. The quick interface device mainly includes a plug-in assembly and a connection assembly. The plug-in assembly 100 includes a mounting block 101, an FTU interface 102, and an aviation plug interface 103. One end of the FTU interface 102 is fixedly connected to the mounting block 101.

One end of the aviation plug interface 103 is fixedly connected to the mounting block 101, and the aviation plug interface 103 is electrically connected to the FTU interface 102 via a wire. Two adjacent mounting blocks 101 are connected by a connecting assembly 200. The connecting assembly 200 includes a connecting seat 201, a fixed sleeve 202, and a movable piece 203.

[0042] like Figure 2 and Figure 3As shown, a first limiting component 300 is provided within the connecting assembly 200. One end of the first limiting component 300 is movably connected to the connecting seat 201, and the other end meshes with the limiting gear 205. Further, in this embodiment, the first limiting component 300 includes an arc-shaped toothed plate 301 and a connecting frame 302.

[0043] Furthermore, please continue to refer to... Figure 2 and Figure 3 In this embodiment, the first limiting component 300 also includes a horizontal plate 303. One side of the horizontal plate 303 is fixedly connected to the connecting frame 302, and the other side of the horizontal plate 303 is fixedly connected to a first spring 305. The end of the first spring 305 is fixedly connected to a connecting plate 306. One end of the connecting plate 306 is fixedly connected to the connecting seat 201. A transmission rod 307 is fixedly connected to the central axis of the horizontal plate 303. The transmission rod 307 passes through the inner cavity of the fixing sleeve 202.

[0044] like Figures 2-3 As shown, in this embodiment, a second limiting component 400 is provided inside the connecting component 200. The second limiting component 400 includes a traction rod 401, a movable sleeve 402, a friction boss 403, and a rotating rod 404. The movable sleeve 402 is sleeved on the outer wall of the rotating rod 404. One end of the traction rod 401 is fixedly connected to the movable sleeve 402, and the other end of the traction rod 401 passes through the inner cavity of the fixed sleeve 202. The friction boss 403 is provided on the outer wall of the rotating rod 404. One end of the rotating rod 404 is movably connected to the connecting seat 201, and the other end of the rotating rod 404 is fixedly connected to a locking gear 405, which meshes with the limiting gear 205.

[0045] like Figure 4 As shown, in this embodiment, the connecting component 200 is provided with a driving component 500. The driving component 500 includes a round rod 501, a handle 502, a displacement plate 503, and a conical block 504. One end of the round rod 501 is fixedly connected to the handle 502, and the other end of the round rod 501 is fixedly connected to the displacement plate 503. One end of the conical block 504 is connected to the displacement plate 503. The outer wall of the conical block 504 abuts against the outer wall of the transmission rod 307. The outer wall of the displacement plate 503 is connected to the traction rod 401.

[0046] like Figure 4 As shown, the connection component 200 in this embodiment is provided with an unlocking component 600. The unlocking component 600 includes an unlocking rod 601 and an unlocking plate 602. One end of the unlocking rod 601 is fixedly connected to the displacement plate 503, and the other end of the unlocking rod 601 is fixedly connected to the unlocking plate 602.

[0047] Furthermore, the unlocking component 600 also includes a locking pin 603, one end of which is fixedly connected to the unlocking plate 602, and the other end of which extends through to the outside of the fixing sleeve 202. The outer wall of the fixing sleeve 202 has a through hole that mates with the locking pin 603, and the outer wall of the unlocking rod 601 is fixedly connected to a sliding rod 604. The inner wall of the fixing sleeve 202 has a sliding groove 605 that mates with the sliding rod 604.

[0048] Please continue to refer to this. Figure 4 In this embodiment, the connecting component 200 is provided with a spring-loaded component 700. The spring-loaded component 700 includes a sleeve rod 701, a movable rod 702, and a second spring 703. One end of the movable rod 702 is slidably connected to the inner wall of the sleeve rod 701. Both ends of the second spring 703 are fixedly connected to the sleeve rod 701 and the movable rod 702, respectively. The other end of the movable rod 702 abuts against the side wall of the unlocking plate 602.

[0049] like Figure 1 As shown, before starting work, the quick-connect device of the pole-mounted switch controller is initially in a locked state, and the movable piece 203 cannot rotate at this time. The quick-connect device of the pole-mounted switch controller is elongated in shape, and each mounting block 101 has a different FTU interface 102 installed on its surface. When connecting and using it, the operator selects the appropriate FTU interface 102 for connection, that is, adjusts it to... Figure 5 The connection is made in a state that allows for easy connection in confined spaces. Multiple FTU interfaces 102 are electrically connected to aviation plug interfaces 103, making the connection more convenient.

[0050] When the quick-connect device of the pole-mounted switch controller needs adjustment, the operator moves the locking pin 603 to retract it into the inner cavity of the fixing sleeve 202. Through the elastic reset of the spring component 700, the unlocking rod 601 and the unlocking plate 602 are moved, thereby driving the drive component 500 to move. When the drive component 500 moves, the sliding of the conical block 504 lifts the transmission rod 307, causing it to move. Through the movement of the transmission rod 307, the horizontal plate 303 and the connecting frame 302 move as a whole, which in turn drives the arc-shaped toothed plate 301 to move, releasing it from the meshing limit of the limit gear 205. At this time, the first spring 305 is compressed, providing elastic energy for the reset locking of the equipment. When the drive assembly 500 moves, the movement of the displacement plate 503 drives the traction rod 401 to move, which in turn drives the movable sleeve 402 to move, releasing it from its limiting position on the friction boss 403. This allows the rotating rod 404 to rotate freely, releasing it from its meshing limitation on the limiting gear 205. With the limiting gear 205 released, the movable piece 203 can rotate freely, causing the two adjacent mounting blocks 101 to rotate relative to each other. This allows the operator to adjust the FTU interface 102 to be inserted, isolating it for easy insertion.

[0051] After the quick-connect device of the pole-mounted switch controller is adjusted, the operator presses the handle 502 to reset the device and restore the locking state. It should be emphasized that the number of mounting blocks 101 and FTU interfaces 102 used in this embodiment can be freely selected and adapted by the operator according to actual needs. In the process of using the quick-connect device of the pole-mounted switch controller, if a narrow docking environment is encountered, the operator can freely and quickly adjust the connection angle between multiple sets of mounting blocks 101 to adjust the required mounting blocks 101 and FTU interfaces 102 to the bottom for easy plugging and use.

[0052] Example 2

[0053] This embodiment provides a quick interface device for a pole-mounted switch controller. The difference between this device and Embodiment 1 is that the spring-loaded component 700 in this embodiment is a hydraulic push rod (not shown in the figure). One end of the hydraulic push rod abuts against the unlocking plate 602, and the other end abuts against the inner wall of the fixing sleeve 202. The hydraulic push rod can extend and retract under external force. Of course, the spring-loaded component in this embodiment is not limited to a hydraulic push rod; other components with spring-loaded functionality can be used instead, which will not be elaborated here.

[0054] The remaining structure of the quick interface device of the pole-mounted switch controller in this embodiment is the same as that in Embodiment 1, and will not be described in detail here.
