Description
Technical Field
[0001] This invention relates to the field of high-voltage drain line installation technology, and in particular to a drain line for high-voltage transmission lines that is easy to connect and disconnect. Background Technology
[0002] As one of the core components of the power system, the high-voltage transmission busbar plays an important role in the transmission and distribution of electrical energy. The busbar transmits the electrical energy from the generator outlet to the substation, and directly connects to various electrical equipment such as transmission lines, transformers, and switches within the substation. When performing maintenance and repair of lines, optimizing power distribution, and protecting equipment and lines, it is often necessary to use jumper wires to connect the busbar and the jumper wires next to the busbar to achieve uninterrupted maintenance, overload protection, and balanced current distribution.
[0003] Existing technologies already have various devices for connecting and disconnecting drain lines to busbars. However, when connecting to the busbar, due to the high-voltage current at the connection point, remote operation or operation via a robotic arm is required. This often involves the problem of positioning the bolt openings between the connecting plates. There is a lack of a convenient connection structure that can quickly and accurately position the connection. Moreover, after the drain line is connected to the busbar, the drain line, which is in a suspended state, will sway to a certain extent under the action of wind. When the drain line sways, the two ends of the drain line will pull on the connection structure between the drain line and the busbar, which may even cause tearing damage to the connection structure in severe cases. Furthermore, severe swaying of the drain line may cause the drain line to come into contact with other equipment or affect the operation of other equipment. Summary of the Invention

Detailed Implementation
[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0028] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.
[0029] Example 1, referring to Figures 1-7 This embodiment provides a high-voltage transmission line feeder that is easy to connect and disconnect, including a disassembly and assembly mechanism 1. The disassembly and assembly mechanism 1 facilitates the connection of the feeder 3 to the busbar or jumper wire of the transmission line. The disassembly and assembly mechanism 1 includes a hook plate 11 for hooking onto the busbar and a connecting plate 12 disposed on the side of the hook plate 11. Figure 2 As shown, when connecting the busbar, the hook plate 11 hooks onto the busbar, and then the connecting plate 12 closes with the hook plate 11, installing the disassembly and assembly mechanism 1 and the entire drain line structure onto the busbar.
[0030] The connecting mechanism 2 is located below the disassembly and assembly mechanism 1. The connecting mechanism 2 includes a receiving plate 21, which is the main load-bearing structure in the connecting mechanism 2. The top of the receiving plate 21 is connected to the disassembly and assembly mechanism 1. The receiving plate 21 has a cavity inside and a stabilizing structure 27 for reducing the large swaying of the drain line 3 inside the receiving plate 21. The drain line 3 is located below the connecting mechanism 2.
[0031] Furthermore, the cross-section of the hook plate 11 is arc-shaped, and an opening is provided on the side of the hook plate 11, such as... Figure 2 As shown, preferably, the cross-section of the hook plate 11 is an arc shape, and the inner diameter of the arc of the hook plate 11 is slightly larger than the outer diameter of the busbar to be overlapped. An entrance for the busbar is left at the bottom of the hook plate 11, and the edge of the hook plate 11 near the opening is rotatably connected to the composite plate 12. A stop block 14 is provided on the side of the composite plate 12 near the hook plate 11, such as... Figure 3 As shown, preferably, the abutment 14 and the composite plate 12 are an integral structure, or the abutment 14 and the composite plate 12 are two structures that are fixedly connected; the rotatable connection between the composite plate 12 and the hook plate 11 is located on one side of the bottom inlet of the hook plate 11, and the composite plate 12 rotates about the bottom inlet side of the hook plate 11 as the rotation axis. The rotation direction of the composite plate 12 is away from or towards the hook plate 11, thereby realizing the opening and closing of the bottom inlet of the hook plate 11.
[0032] Furthermore, a first elastic element 13 is provided on the outer side of the composite plate 12. The end of the first elastic element 13 away from the composite plate 12 is connected to the hook plate 11. The first elastic element 13 is in a stretched state. A locking plate 15 is provided on the end of the composite plate 12 away from the hook plate 11. A threaded rod 16 is provided on the outer wall of the locking plate 15. A fixing plate 17 is provided at the bottom of the hook plate 11. A threaded groove 18 is formed on the surface of the fixing plate 17. Figure 3 As shown, when the entire assembly / disassembly mechanism 1 is not subjected to external force, the composite plate 12 is lifted by the tension of the first elastic element 13, and the bottom entrance of the hook plate 11 is fully open, allowing the hook plate 11 to be easily hooked onto the busbar. When the hook plate 11 is hooked onto the busbar, the busbar enters the interior of the hook plate 11 and pushes the abutment block 14 upward. The abutment block 14 rotates upward around the hook plate 11, the first elastic element 13 is stretched, and the composite plate 12, which is fixedly connected to the abutment block 14, rotates downward around the hook plate 11 and contacts the fixing plate 17. At this time, a closed space is formed between the composite plate 12 and the hook plate 11, where the closed space between the composite plate 12 and the hook plate 11 is slightly larger than the outer diameter of the busbar. At this time, the locking plate 15 at the bottom of the composite plate 12 contacts the fixing plate 17. Furthermore, the threaded rod 16 on the locking plate 15 is aligned with the threaded groove 18 on the surface of the fixing plate 17, thus completing the accurate positioning of the connecting mechanism 2. At this time, simply rotating the threaded rod 16 is sufficient to install the disassembly and assembly mechanism 1 and the entire drain line structure onto the busbar. When it is necessary to disassemble the drain line 3, simply rotate the threaded rod 16 to completely disengage it from the threaded groove 18, and then slightly lift the entire disassembly and assembly mechanism 1. At this time, a space will appear at the top of the hook plate 11 for the abutment block 14 to rotate downward. Under the elastic force of the first elastic element 13, the first elastic element 13 will lift the connecting plate 12 upward, and the connecting plate 12 will detach from the fixing plate 17. Thus, the bottom of the hook plate 11 will open the entrance again, allowing the disassembly and assembly mechanism 1 and the entire drain line structure to be detached from the busbar, further completing the disassembly of the drain line 3.
[0033] Usage: In existing technologies, a robotic arm is often needed to remotely connect the drain line 3 to the busbar, and the busbar and drain line 3 are usually fastened with bolts. During this process, the connection hole between the busbar and drain line 3 needs to be remotely positioned, either by using a camera to guide manual remote positioning or by setting a fixed algorithm to automatically position it with the camera. However, these methods are very complicated and time-consuming. In contrast, when the drain line 3 needs to be installed on the busbar, this device only requires the robotic arm to hook it... The bottom inlet of plate 11 allows the hook plate 11 to be hooked onto the drain line 3, while simultaneously positioning the connection structure between the locking plate 15 and the fixing plate 17. Positioning is quick and accurate, which can shorten the installation time. After installation, if there is a strong wind, the stabilizing structure 27 will reduce the large swaying of the drain line 3, providing protection for the drain line 3 and the busbar. When it is necessary to remove the drain line 3 from the busbar, simply loosen the threaded rod 16 to disengage it from the fixing plate 17, then the hook plate 11 can be lifted and removed from the busbar.
[0034] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention. Unlike the previous embodiment, when the drain line 3 is connected to the busbar or other conductors, the drain line 3 typically needs to be longer than the distance between the two conductors for installation purposes. Therefore, a section of the drain line 3 will dangle in the air. The drain line 3 will sway due to strong winds. If the swaying is too violent, it can cause the connection structure between the busbar and the drain line 3 to tear. Therefore, in the drain line structure of this embodiment, the top of the receiving plate 21 is connected to the fixing plate 17. Preferably, the top of the receiving plate 21 is fixedly connected to the fixing plate 17. An intermediate shaft 22 is fixedly installed inside the receiving plate 21 and is fixedly connected to the receiving plate 21. A movable connecting block 23 is provided on the outer wall of the intermediate shaft 22. Figure 4 As shown, preferably, the movable connecting block 23 is sleeved on the outer wall of the intermediate shaft 22. The movable connecting block 23 can slide on the outer wall of the intermediate shaft 22 and can also rotate on the outer wall of the intermediate shaft 22. The bottom of the movable connecting block 23 is connected to the guide line 3. When the guide line 3 is connected to the two sets of wires, the two ends of the guide line 3 are fixedly connected to the corresponding movable connecting block 23. When the guide line 3 is affected by the wind and swings, the swing of the guide line 3 will drive the movable connecting block 23 to slide or rotate on the intermediate shaft 22. Since the connection structure is not kept in a fixed position, the tearing force on the connection structure when the guide line 3 swings with the wind will be reduced.
[0035] Usage process: When the diversion line 3 is attached to the busbar, when the diversion line 3 is affected by the wind, the diversion line 3 will drive the movable connecting block 23 to rotate or slide on the intermediate shaft 22. Since the busbar and the diversion line 3 are not directly fixedly connected, the swaying of the diversion line 3 will not directly tear the connection structure, which can reduce the risk of tearing the connection structure.
[0036] Example 3, referring to Figures 1-7 This is the third embodiment of the present invention. Unlike the previous embodiment, the drainage line 3 will sway violently due to strong winds. In this case, the drainage line 3 may collide with other equipment and affect its operation. Therefore, in the drainage line structure of this embodiment, a rotating block 24 is also provided on the outer wall of the intermediate shaft 22. A retainer 25 is provided on the side of the rotating block 24 away from the movable connecting block 23. The side of the retainer 25 is fixedly connected to the receiving plate 21. The rotating block 24 includes a rotating cylinder 241 disposed at one end inside the receiving plate 21. A groove 242 is provided on the outer wall of the rotating cylinder 241, and a protrusion that cooperates with the groove 242 is provided on the inner wall of the retainer 25. Figure 7 As shown, the retainer 25 is cylindrical, and the end face of the retainer 25 is provided with a protrusion that mates with the slide groove 242. The cross-section of the retainer 25 is stepped. Since the protrusion on the inner wall of the retainer 25 is inserted into the slide groove 242 and limits the slide groove 242, the rotating cylinder 241 is fixed and locked in a position close to the inner wall of the receiving plate 21. The rotating cylinder 241 cannot slide along the intermediate shaft 22, but the rotating cylinder 241 can rotate around the intermediate shaft 22.
[0037] Furthermore, the stabilizing structure 27 in this embodiment is actually a scissor-type folding and stretching structure. The stabilizing structure 27 includes a support rod 271 disposed on the outer wall of the rotating block 24, such as... Figure 5 As shown, preferably, the top of the support rod 271 is rotatably connected to the rotating block 24, the side of the support rod 271 is provided with a first connecting rod 272, the first connecting rod 272 is rotatably connected to the support rod 271, the side of the first connecting rod 272 is provided with a stabilizing sleeve 273, and the bottom of the first connecting rod 272 is provided with a second connecting rod 274.
[0038] Furthermore, there are multiple first connecting rods 272 and second connecting rods 274, which are arranged intersectingly, and multiple stabilizing sleeves 273; for example Figure 5As shown, a first link 272 and a support rod 271 are rotatably connected at the middle. The first link 272 and the support rod 271 are simultaneously rotatably connected to two identical sets of stabilizing sleeves 273, and the rotatable connection points are located at both ends of the first link 272 and at two positions on the support rod 271 that are parallel to both ends of the first link 272. Among the remaining first links 272, each first link 272 is rotatably connected at the middle to a corresponding second link 274, and both ends of the first link 272 and the second link 274 are simultaneously rotatably connected to two identical stabilizing sleeves 273. At the same time, a first link 272 and a second link 274 with a rotatable connection at the middle are set as a group of central rotatable connection structures. From the end of the first link 272 and the support rod 271 away from the rotating block 24 to each group of central rotatable connection structures connected in sequence, each pair of adjacent central rotatable connection structures is hinged and connected by sharing a set of stabilizing sleeves 273, thereby forming a foldable and stretchable overall structure of the stabilizing structure 27.
[0039] Furthermore, the stabilizing sleeve 273 is fitted onto the outside of the drain line 3. The inner diameter of the stabilizing sleeve 273 is slightly larger than the outer diameter of the drain line 3. A second elastic element 26 is provided on the side of the rotating block 24 away from the retainer 25. The end of the second elastic element 26 away from the rotating block 24 is connected to the movable connecting block 23. The second elastic element 26 is in a compressed state. Figure 5 As shown, when the weather is normal and there is no strong wind, the end of the drainage line 3 will naturally droop due to its own weight. Under the action of the second elastic element 26, the movable connecting block 23 will move relatively away from the rotating cylinder 241. When affected by strong wind, the drainage line 3 will swing, and the swing of the drainage line 3 will tend to move away from the natural drooping state. On the intermediate shaft 22, the drainage line 3 will drive the movable connecting block 23 to slide along the intermediate shaft 22. At this time, the movable connecting block 23 will move closer to the rotating cylinder 241, and the support rod 271 and the first connecting rod 272 will rotate relative to each other. The stabilizing sleeve 273 will also move downward along the drainage line 3, while the first connecting rod 272 and the second connecting rod 272 will move downward. Relative rotation will also occur between 74, and multiple stabilizing sleeves 273 will move downwards. At the same time, the distance between the stabilizing sleeves 273 will also increase. At this time, the distance between the uppermost and lowermost stabilizing sleeves 273 will increase significantly, and the area covered by the stabilizing sleeves 273 on the drainage line 3 will also increase accordingly. When the drainage line 3 tends to swing violently, the section of the drainage line 3 near the movable connecting block 23, i.e., the end of the drainage line 3, will tend to rise upwards and break away from its natural drooping. However, at this time, the increased coverage of the stabilizing sleeves 273 along the end of the drainage line 3 will keep the end of the drainage line 3 vertical, thus preventing the drainage line 3 from swinging violently and reducing the amplitude of the swing.
[0040] Usage process: After the guide wire structure of this embodiment is attached to the busbar, a section of the bottom of the guide wire 3 will dangle in the air. When the weather is normal and there is no strong wind, the end of the guide wire 3 will naturally droop due to its own weight. Under the action of the second elastic member 26, the movable connecting block 23 will be relatively far away from the rotating drum 241. When affected by strong wind, the guide wire 3 will swing. When the guide wire 3 tends to swing violently, the stabilizing structure 27 will reduce the swing amplitude of the guide wire 3, protect the equipment on both sides of the busbar, and prevent the guide wire 3 from swinging and colliding with the equipment on both sides of the busbar or affecting the operation of other equipment.
[0041] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
