[0001] This utility model relates to the field of live-line working technology in power distribution, and in particular to a remote-controlled live-line connection mechanism for diverting power lines. Background Technology

[0002] Traditional live-line work in power distribution requires the use of large bypass equipment, which is difficult to transport and complex to operate. Live-line work can only be carried out after the lead wires have been disconnected and reconnected, which increases the power outage time for users and greatly reduces the effective working time for live-line work. The excessive preparation time for live-line work leads to low efficiency of the work project, and the frequency and duration of the work increase the risk of live-line work. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a remote-controlled live-line splicing mechanism for lead wires. This mechanism enables rapid disconnection and splicing of lead wires, reducing power outage time and improving the efficiency of live-line operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A remote-controlled live-line splicing mechanism for a drain wire includes a fixed bracket mounted on a pole crossarm, a wiring contact assembly mounted on the fixed bracket and connected to a main cable, and an on / off drive assembly mounted on the fixed bracket and connected to the drain wire. The on / off drive assembly and the wiring contact assembly constitute an electric switch structure. The on / off drive assembly controls the movement of its conductive stepping screw to contact or disconnect from the main cable, thereby enabling splicing or disconnection between the main cable and the drain wire.

[0006] Furthermore, the fixed bracket is made of channel steel, and connecting plates are formed on both sides of the channel steel, which are bolted to the crossarm of the tower through the connecting plates.

[0007] Furthermore, the wiring contact assembly includes a first porcelain insulator installed on one side of the top of the fixed bracket. The bottom of the first porcelain insulator is fixedly connected to the fixed bracket, and a copper sheet contact seat is installed on the top.

[0008] Furthermore, the copper sheet contact seat includes an insulator connecting plate located at the bottom, and a set of triangular support plates symmetrically installed on the insulator connecting plate; a gap is formed between the set of triangular support plates to cooperate with the movement of the conductive stepping screw, and a metal hoop for fixing the main cable is installed on the top of each set of triangular support plates.

[0009] Furthermore, the on / off drive assembly includes a drain line support arm, which has a V-shaped structure and includes a first support arm and a second support arm; one end of the first support arm is fixedly installed on the other side of the top of the fixed bracket, and the other end extends outward from the fixed bracket, with a lower wire seat for installing the drain line installed at the end; one end of the second support arm is fixedly connected to the first support arm.

[0010] Furthermore, the lower wire seat is a cylindrical structure with a through hole for the guide wire to pass through, and an arc-extinguishing chamber is provided inside the lower wire seat.

[0011] Furthermore, the on / off drive assembly also includes a second porcelain insulator installed on the other side of the top of the fixed bracket. The bottom of the second porcelain insulator is fixedly connected to the fixed bracket, and a drive box is installed on the top. The other end of the second support arm is fixedly connected to the top of the second porcelain insulator.

[0012] Furthermore, a conductive stepper screw is connected to the drive box, and a stepper motor, a circuit board connected to the stepper motor, and a lithium battery connected to the stepper motor and the circuit board are installed inside the drive box. A first bevel gear is installed on the output end of the stepper motor, and a mounting base is also provided inside the drive box.

[0013] Furthermore, the conductive stepping screw has a contact at its front end, an insulating skirt is installed on the section of the rod near the contact, and the rear end of the rod is connected to the drain line; the conductive stepping screw is also provided with a guide groove, and the mounting base is also provided with a guide block that cooperates with the guide groove.

[0014] This remote-controlled live-connecting drain wire mechanism has the following beneficial effects:

[0015] This remote-controlled live-line splicing mechanism for lead wires is relatively small in size. After being installed on a utility pole, it can be connected to the main cable via a wiring contact assembly and to the lead wire via a switching drive assembly. Once both the main cable and the lead wire are installed, the drive box of the switching drive assembly is activated remotely to control the movement of the conductive stepping screw to make or break contact with the main cable.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0022] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] This embodiment provides a remote-controlled live-line connection mechanism, such as... Figure 1 As shown, the remote-controlled live-line splicing and draining mechanism includes a fixed bracket 1 installed on the crossarm of the tower. The fixed bracket 1 is made of channel steel, and connecting plates 4 are formed on both sides of the channel steel. It is bolted to the crossarm of the tower through the connecting plates 4. The fixed bracket 1 serves as the support structure for the entire remote-controlled live-line splicing and draining mechanism, ensuring that each component is fixed in the appropriate position and providing stability and support.

[0024] like Figure 1 As shown, the remote-controlled live-line splicing and draining mechanism also includes a wiring contact assembly 2 mounted on the fixed bracket 1 and connected to the main cable 10. The function of the wiring contact assembly 2 is to fix the main cable 10 and ensure the stability of the splice position. Figure 1 As shown, the wiring contact assembly 2 in this embodiment includes a first porcelain insulator 5 installed on one side of the top of the fixed bracket 1. The porcelain insulator provides electrical insulation, preventing current from flowing along the external path of the equipment and ensuring the safe and reliable operation of the equipment. The bottom of the first porcelain insulator 5 is fixedly connected to the fixed bracket 1, and a copper plate contact seat 6 is installed on the top. The copper plate contact seat 6 is used to fix the main cable 10. The copper plate contact seat 6 includes an insulator connecting plate 7 located at the bottom and a set of triangular support plates 8 symmetrically installed on the insulator connecting plate 7. A gap is formed between the set of triangular support plates 8, and a metal clamp 9 for fixing the main cable 10 is installed on the top of each set of triangular support plates 8.

[0025] like Figure 1 As shown, the remote-controlled live-line connection mechanism also includes an on / off drive assembly 3 mounted on the fixed bracket 1 and connected to the lead-in cable 11; the on / off drive assembly 3 functions to install and fix the lead-in cable 11, and simultaneously control whether the lead-in cable 11 is connected to the main cable 10. Figure 1 and Figure 2 As shown, the switching drive assembly 3 includes a drain wire support arm 12, which is used to install and fix the drain wire 11. The drain wire support arm 12 has a V-shaped structure and includes a first support arm 13 and a second support arm 14 made of epoxy board insulation material. One end of the first support arm 13 is fixedly installed on the other side of the top of the fixed bracket 1, and the other end extends outward from the fixed bracket 1, with a lower wire seat 15 for installing the drain wire 11 installed at its end. One end of the second support arm 14 is fixedly connected to the first support arm 13. The lower wire seat 15 has a cylindrical structure with a through hole for the drain wire 11 to pass through. The lower wire seat 15 also has an arc-extinguishing chamber inside. The arc-extinguishing chamber's function is to suppress the formation of an electric arc and control the arc discharge during power failure, protecting the equipment and the environment from potential damage caused by the arc.

[0026] like Figure 1As shown, the switching drive assembly 3 also includes a second porcelain insulator 16 installed on the other side of the top of the fixed bracket 1. The porcelain insulator provides electrical insulation, preventing current from flowing along the external path of the equipment and ensuring the safe and reliable operation of the equipment. The bottom of the second porcelain insulator 16 is fixedly connected to the fixed bracket 1, and the top is equipped with a drive box 17; the other end of the second support arm 14 is fixedly connected to the top of the second porcelain insulator 16. The drive box 17 controls its conductive stepping screw 18 to move and contact or disconnect from the main cable 10, so that the main cable 10 and the lead wire 11 are connected or disconnected.

[0027] Furthermore, in this embodiment, the drive box 17 drives the conductive stepper screw 18 using the following driving method: such as... Figure 3 As shown, in this embodiment, a conductive stepper screw 18 is connected to the drive box 17. Inside the drive box 17, a stepper motor 19, a circuit board 20 connected to the stepper motor 19, and a lithium battery 21 connected to the stepper motor 19 and the circuit board 20 are installed. The circuit board 20 is equipped with a remote control. The lithium battery 21, stepper motor 19, the remote control circuit board 20 for the stepper motor 19, and the remote control are all commercially available finished products. Figure 3 As shown, a first bevel gear 22 is mounted on the output end of the stepper motor 19. A mounting base 23 is also provided inside the drive box 17. A threaded sleeve 24, passing through the mounting base 23, is rotatably mounted on the mounting base 23 via a bearing. The threaded sleeve 24 is fitted onto the conductive stepper screw 18 and is threadedly connected to it. A second bevel gear 25, meshing with the first bevel gear 22, is fixedly fitted onto the threaded sleeve 24. The front end of the electric stepper screw has a contact 26, and an insulating skirt 27 is mounted on the section of its rod near the contact 26. The rear end of its rod is connected to the drain wire 11. The conductive stepper screw 18 also has a guide groove 28, and a guide block (not shown in the figure) is provided inside the mounting base 23 to cooperate with the guide groove 28.

[0028] The working principle of this remote-controlled live-connected drain wire mechanism is as follows:

[0029] The remote-controlled live-connected lead wire mechanism is installed on the pole via a fixed bracket 1, and then connected to the main cable 10 via a wiring contact assembly 2 to fix the position of the main cable 10. At the same time, the lead wire 11 is installed via the lead wire support arm 12 of the on / off drive assembly 3, and the end of the lead wire 11 is passed through the lower wire seat 15 and connected to the conductive stepping screw 18.

[0030] After the main cable 10 and the drain wire 11 are installed, each time the drain wire 11 needs to be spliced, the stepper motor 19 in the drive box 17 is started by the remote control. After the stepper motor 19 is started, the output end of the stepper motor 19 drives the first bevel gear 22 to rotate at high speed. Since the first bevel gear 22 meshes with the second bevel gear 25, the high-speed rotation of the first bevel gear 22 drives the second bevel gear 25 and the threaded sleeve 24 to rotate at high speed relative to the mounting base 23. Since the threaded sleeve 24 is threadedly connected to the conductive stepper screw 18, and since one end of the conductive stepper screw 18 is connected to the drain wire 11, it is limited by the rotation of the drain wire 11, and limited by the guide groove 28 and guide block on the conductive stepper screw 18. Therefore, the conductive stepper screw 18 moves forward or backward when the threaded sleeve 24 rotates at high speed.

[0031] When the contact 26 at the front end of the conductive stepper screw 18 extends into the gap between a set of triangular support plates 8 and contacts the main cable 10, the main cable 10 forms a current path with the lead wire 11 through the conductive stepper screw 18, completing the connection of the lead wire 11; conversely, when the remote control controls the stepper motor 19 to run in reverse, the main cable 10 and the conductive stepper screw 18 lose contact, the current path is broken, and the connection of the lead wire 11 is released.

[0032] In summary, this remote-controlled live-line splicing mechanism for the lead wire forms an electric switch structure through the on / off drive assembly 3 and the wiring contact assembly 2. The on / off drive assembly 3 controls its conductive stepping screw 18 to move and contact or disconnect from the main cable 10, so that the main cable 10 and the lead wire 11 can be spliced ​​or disconnected, thereby enabling rapid disconnection and splicing of the lead wire 11, reducing the user's power outage time, and improving the efficiency of live-line work.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
