Description
Technical Field
[0001] This invention relates to the field of emergency power repair technology, specifically to a temporary emergency power supply device for a broken circuit switch in a power distribution line. Background Technology
[0002] Power distribution lines are a crucial component of the power system, responsible for transmitting electrical energy from substations to end users. However, in actual operation, power distribution lines may face various challenges, such as severe weather, external damage, and equipment aging, all of which can lead to line breaks, thus affecting the reliability and stability of power supply. When a power distribution line breaks, timely emergency handling is necessary to ensure the continuity and stability of power supply. Traditional methods for handling line breaks typically require de-energizing the area at the break point and dismantling all overhead conductors near the break point to the ground, then using splicing conduits for crimping. This method is inconvenient, time-consuming, and requires specialized equipment and personnel, causing considerable inconvenience to residents and businesses.
[0003] In summary, this invention proposes an emergency temporary power supply device for power distribution line switches in the event of a line breakage, which simplifies the operation process, reduces the difficulty of operation, and accelerates the safe and efficient connection of the broken line. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides an emergency temporary connection power supply device for power distribution line switches in the event of a broken wire. By cooperating with the cutting component, fixing component, clamping component, and contact component, the device simplifies the operation process of emergency temporary connection in the event of a broken wire, reduces the difficulty of operation, and accelerates the safe and efficient connection of the broken wire.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A temporary emergency power supply device for disconnected wires in a power distribution line switch includes a housing and a controller. A safety cover for sealing the housing is hinged to the top of the housing. A switch assembly for controlling the connection of two disconnected wires is installed on one side of the housing. Two fixing assemblies for fixing the two disconnected wires are symmetrically installed on the other side of the housing. Two cutting assemblies for cutting the wire sheaths are installed inside the housing, with each cutting assembly corresponding to one of the fixing assemblies. Movable grooves are formed on both sides of the inner wall of the housing. Each movable groove contains a threaded rod that rotatably engages with the housing. One end of each threaded rod is coaxially fixedly connected to a first movable bevel gear. Each first movable bevel gear meshes with a second movable bevel gear. Each component is coaxially fixedly connected to a movable shaft that rotates with the housing. One end of each movable shaft is fixedly connected to an electromagnetic clutch electrically connected to the controller. Inside the housing, there is a movable block threadedly connected to a threaded rod. Inside the movable block, symmetrical clamping components for clamping the stripped portion of the wire are arranged along the length of the movable block. Inside the housing, symmetrically installed are drive components for driving the clamping components to clamp the wire and the cutting components to cut the wire shell. The drive components correspond to the electromagnetic clutches. Inside the housing, there are contact components for cleaning the stripped wire shell and for being driven by the switch component to connect the two broken wires. One side of the contact components is fixedly connected to the switch component. The drive components, clamping components, fixing components, and switch components are all electrically connected to the controller.
[0006] Basic Scheme Principle: A fixing component initially secures the two broken wires extending into the housing, reducing the likelihood of them rotating during subsequent cutting of the wire casing. A drive component synchronously rotates the cutting component and linearly moves the clamping component, separating the broken portion of the wire casing from the main casing. Simultaneously, the clamping component clamps this separated portion. An electromagnetic clutch controls the closure of the drive component and the moving shaft, causing the threaded rod to rotate synchronously with the drive component. This moves the moving block axially along the threaded rod, peeling the separated portion of the wire casing. As the moving block moves towards the contact component, the contact component removes the peeled casing from the clamping component. The moving block then resets, and the clamping component clamps the peeled portion again. Finally, the opening or closing of the switch component controls whether the contact component contacts or de-contacts the clamping component, thus completing the connection of the broken wires and the switching function.
[0007] The above approach has the following beneficial effects:
[0008] 1. The fixing components in this solution ensure the stability of the broken wire during the cutting process, avoiding inaccurate cutting or damage to other parts caused by wire swaying. They also ensure that the wire is securely held inside the enclosure after subsequent reconnection, facilitating safe and efficient switching. Furthermore, by synchronously driving the cutting and clamping components through the drive component, the wire sheath is simultaneously subjected to the fixing forces of the clamping and fixing components at both ends when being cut. This reduces the possibility of slippage in the cutting component, further improving cutting efficiency and accelerating the overall wire reconnection speed. It also makes the stripping and clamping operations of the wire sheath more precise and efficient.
[0009] 2. This solution achieves smooth movement of the moving block through the cooperation of the drive assembly and the threaded rods, thereby accurately removing the stripped wire sheath from the clamping assembly. This not only improves operational precision but also reduces the risk of equipment damage or personal injury due to improper operation. Simultaneously, the double-threaded rod design makes the moving block more stable during movement, less prone to deviation or wobbling. Furthermore, the double-threaded rod design also distributes the load, reducing the stress on individual threaded rods and thus extending their service life.
[0010] 3. The design of the contact and switch components in this solution makes disconnection and switching operations more flexible and reliable. By controlling the contact and clamping components to make or break contact, disconnection and reconnection of broken wires can be achieved safely and quickly, thus fulfilling the switching function and meeting different power supply needs.
[0011] 4. Compared to existing manual or traditional mechanical methods of disconnecting wires, this solution's emergency temporary power supply device automates operation, significantly improving work efficiency and safety. A controller centrally manages the operation of each component, reducing manual intervention and lowering operational difficulty and complexity.
[0012] 5. This solution utilizes a drive assembly to synchronously drive the cutting and clamping assemblies, achieving rapid and precise cutting and clamping operations, significantly reducing the time required for wire breakage repair. Simultaneously, an electromagnetic clutch controls the connection between the moving shaft and the drive assembly. When the drive assembly is connected to the moving shaft, the threaded rod can be rotated via the drive assembly, thus controlling the movement of the moving block along the threaded rod. Therefore, according to the wire breakage repair process, the same drive assembly can complete different processing actions for the broken wire, reducing the overall weight of the device, making it easy to carry, and allowing for rapid deployment to the emergency repair site for wire breakage repair.
[0013] Furthermore, each fixing component includes a fixing port that is fixed to the surface of the box and communicates with the inside of the box. Inside the fixing port, there are several first telescopic rods arranged in a circular array along its inner wall. The output part of each first telescopic rod is fixedly connected to an arc-shaped fixing plate. Each first telescopic rod is electrically connected to the controller.
[0014] Beneficial effects: The telescopic function of the first telescopic rod allows for flexible adjustment of the position of the arc-shaped fixing plate to accommodate wires or cables of different diameters, thereby expanding the applicability of the device. Furthermore, precise control of the telescopic length and speed of the first telescopic rod ensures that the wires or cables are quickly and accurately positioned during the connection process, improving connection efficiency and shortening fault recovery time. Additionally, the arc-shaped fixing plate design allows for a close fit to the outer surface of the wires or cables, providing stable support and fixation. This helps prevent the wires or cables from shifting or detaching during subsequent cutting and stripping of the outer casing, as well as during the connection of the contact assembly and clamping assembly, thus improving the overall safety and reliability of the device.
[0015] Furthermore, each cutting component includes a limiting ring fixed to the inner wall of the housing and corresponding to the fixing opening. The limiting ring has an annular groove, and a rotating ring is slidably fitted into the annular groove. Several second telescopic rods are arranged in a circular array along the inner wall of the rotating ring. Each of the second telescopic rods has a cutting blade fixedly connected to its output part. A driving gear and a driven gear mesh on the outer surface of the rotating ring. Both the driving gear and the driven gear are located inside the housing and are rotatably connected to the housing. Each of the second telescopic rods is electrically connected to the controller.
[0016] Beneficial effects: The telescopic function of the second telescopic rod allows for precise adjustment of the cutting blade position, ensuring accurate and rapid cutting of wires or cables, improving cutting precision and efficiency, reducing losses due to improper cutting, and enabling automated cutting of wire or cable sheaths of different diameters. The sliding fit design of the rotating ring and annular groove, along with the meshing transmission of the driving and driven gears, ensures the stability and reliability of the cutting assembly during the cutting process.
[0017] Furthermore, the drive components all include a dual-axis motor disposed inside the housing. One output shaft of the dual-axis motor is coaxially and fixedly connected to the drive gear, and the other output shaft of the dual-axis motor is coaxially and fixedly connected to a first bevel gear. The first bevel gear meshes with a second bevel gear. The second bevel gear is coaxially and fixedly connected to a first rotating shaft that rotates with the housing. One end of the first rotating shaft corresponds to the electromagnetic clutch, and the bottom of the first rotating shaft is coaxially and fixedly connected to the first gear. The first gear meshes with the second gear. Both dual-axis motors are electrically connected to the controller.
[0018] Beneficial effects: As a drive source, the dual-axis motor can provide power output in two directions simultaneously, thereby transmitting power to the clamping assembly and the rotating ring at the same time. This allows the clamping and cutting processes to proceed synchronously, accelerating the docking efficiency. At the same time, when the rotating ring drives the cutting blade to cut the broken wire shell, the synchronous clamping of the clamping assembly will further stabilize the broken wire, thereby further improving cutting efficiency and quality, and thus improving the integrity of the subsequent shell peeling.
[0019] Furthermore, each clamping assembly includes a third gear meshing with the second gear. The third gear is coaxially and fixedly connected to a second rotating shaft that rotates with the interior of the moving block. The second rotating shaft is threadedly connected to a nut seat, forming a ball screw structure. A push rod is fixedly connected to the bottom end of the nut seat. The surface of the moving block has two clamping through holes corresponding to the fixing opening, and the interior of the moving block has two clamping grooves corresponding to the clamping through holes. The bottom end of the push rod extends through the moving block into the clamping groove and is fixedly connected to a clamping recess. The groove of the clamping recess has a semi-elliptical structure. A rubber layer is fixedly connected to the surface of the groove of the clamping recess, and a pressure sensor is provided at the connection between the clamping recess and the rubber layer. The pressure sensors are all electrically connected to the controller.
[0020] Beneficial effects: Through the meshing transmission of the second and third gears and the application of a ball screw structure, precise control of the push rod and clamping recess is achieved. This allows for adaptive adjustment according to different wire or cable sizes, ensuring moderate clamping force and preventing damage to the wires or cables. The groove of the clamping recess is designed with a semi-elliptical structure, which better adapts to the shape of the wire or cable, ensuring uniform and reliable clamping. Simultaneously, the semi-elliptical structure also helps reduce compression and deformation of the wire or cable during clamping. The rubber layer increases the friction between the clamping recess and the wire or cable, improving the stability of the clamping effect. Furthermore, the rubber layer acts as a buffer, reducing wear and damage to the wire or cable during clamping.
[0021] The application of pressure sensors can monitor the clamping force of the clamping blocks on the wires or cables in real time and feed the signal back to the controller, so that the user or controller can understand the clamping status in a timely manner and make adjustments as needed to ensure that the clamping force is appropriate. Thus, by precisely controlling the clamping force and monitoring the clamping status in real time, the design of the clamping components improves the safety and reliability of the entire device.
[0022] Furthermore, an isolation plate is installed inside the box near the limiting ring, and the isolation plate is located between the two limiting rings. Two support frames corresponding to the clamping through holes are screwed to both sides of the inner wall of the box along the length direction.
[0023] Beneficial effects: The design of the separator plate divides the movement space of the two broken wires, allowing the two wire ends to be quickly positioned into the corresponding clamping through holes. It also reduces the possibility of direct contact between the two stripped wire segments during the splicing process, further improving safety. The two support brackets corresponding to the clamping through holes provide additional support and fixation for the wires or cables. During clamping, the support brackets ensure the stability of the wires or cables, preventing deformation or movement due to uneven force, thus improving the clamping effect and increasing the efficiency of positioning the broken wire ends into the clamping through holes.
[0024] Furthermore, the contact assembly includes a support plate fixedly connected to the switch assembly. Two copper contact posts are fixedly connected to the end of the support plate away from the self-locking button, and the two contact posts are cylindrical boss structures.
[0025] Beneficial effects: The copper contact posts possess excellent electrical conductivity and corrosion resistance, ensuring a stable electrical connection when they contact the inner wall of the clamping through-hole. The cylindrical boss structure increases the contact area, further improving the reliability and stability of the electrical contact. The contact assembly is fixedly connected to the telescopic part of the self-locking button via a support plate, enabling precise movement as the self-locking button is pressed and released. This ensures the accuracy and reliability of the contacts during closing and opening, reducing circuit failures caused by inaccurate contact positioning.
[0026] Furthermore, the switch assembly includes a self-locking button installed on the side of the enclosure away from the fixing port. The self-locking button extends through the enclosure into the interior of the enclosure and is fixedly connected to the support plate. The self-locking button slides with the enclosure. It also includes an indicator light on the safety cover. The input and output ends of the indicator light are electrically connected to a contact post and the input end of the self-locking button, respectively. The output end of the self-locking button is electrically connected to another contact post.
[0027] Beneficial effects: By fixing the self-locking button to the contact assembly and combining it with the circuit design of the indicator light, the circuit status can be displayed intuitively and controlled precisely. Users can judge whether the circuit is closed or open by observing the on / off state of the indicator light, thus making it easier to manage the circuit and troubleshoot.
[0028] The self-locking button design allows it to remain locked after being pressed until it is pressed again to release the lock. This helps prevent accidental circuit closure or opening due to misoperation or external interference, thus improving the safety and reliability of the circuit.
[0029] Furthermore, a discharge port communicating with the interior of the box is opened at the bottom of the box, and a baffle for controlling the opening and closing of the discharge port is hinged to the bottom of the box.
[0030] Beneficial effects: The baffle is connected to the box body by a hinge, which can flexibly open or close the discharge port to achieve rapid discharge of the peeled shell, thereby avoiding the accumulation of peeled shell inside the box and affecting subsequent work.
[0031] Furthermore, several rubber pads are provided at the bottom of the box.
[0032] Beneficial effects: As a material with high volume resistivity and resistance to electrical breakdown, the rubber pad can effectively isolate the electrical connection between the enclosure and the ground. When a broken wire occurs inside the enclosure, the rubber pad can prevent current from leaking to the ground through the bottom of the enclosure, thus providing an extra layer of insulation protection and further improving the safety of the device.

[0049] The following detailed description illustrates the specific implementation method:
[0050] Example 1:
[0051] As attached Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown: An emergency temporary connection power supply device for a power distribution line switch includes a housing 1 and a controller. A safety cover 2 for sealing the housing 1 is hinged to the top of the housing 1. A switch assembly for controlling the connection of two broken wires is installed on one side of the housing 1. Two fixing assemblies for fixing the two broken wires are symmetrically installed on the other side of the housing 1. Two cutting assemblies for cutting the wire sheaths are installed inside the housing 1, with each cutting assembly corresponding to one of the fixing assemblies. Movable grooves 12 are formed on both sides of the inner wall of the housing 1. Each movable groove 12 contains a threaded rod 13 that rotatably engages with the housing 1. One end of each threaded rod 13 is coaxially fixedly connected to a first movable bevel gear 34. Each first movable bevel gear 34 meshes with a second movable bevel gear 35, which is coaxially fixed... A movable shaft 36 is fixedly connected to the housing 1 and rotates in coordination with it. One end of the movable shaft 36 is fixedly connected to an electromagnetic clutch 37 that is electrically connected to the controller. Inside the housing 1, there is a movable block 7 that is threadedly connected to the threaded rod 13. Inside the movable block 7, there are clamping components symmetrically arranged along the length of the movable block 7 for clamping the stripped part of the wire. Inside the housing 1, there are drive components symmetrically installed for driving the clamping components to clamp the wire and the cutting components to cut the wire shell. The drive components correspond to the electromagnetic clutches 37. Inside the housing 1, there are contact components for cleaning the stripped wire shell and for being driven by the switch component to connect the two broken wires. One side of the contact component is fixedly connected to the switch component. The drive component, clamping component, fixed component and switch component are all electrically connected to the controller.
[0052] Each fixing component includes a fixing port 6 integrally formed on the surface of the housing 1 and communicating with the interior of the housing 1. Several first telescopic rods 14 are arranged in a circular array along the inner wall of the fixing port 6. The output part of each first telescopic rod 14 is screwed to an arc-shaped fixing plate 15. Each first telescopic rod 14 is electrically connected to the controller.
[0053] Each cutting assembly includes a limiting ring 8 integrally formed on the inner wall of the housing 1 and corresponding to the fixing port 6. The limiting ring 8 has an annular groove, and a rotating ring 16 is slidably fitted into the annular groove. Several second telescopic rods 17 are arranged in a circular array along the inner wall of the rotating ring 16. Each of the output parts of the second telescopic rods 17 is screwed to a cutting blade 18. A driving gear 19 and a driven gear 20 are symmetrically meshed on the outer surface of the rotating ring 16. Both the driving gear 19 and the driven gear 20 are located inside the housing 1 and are rotatably connected to the housing 1. Each of the second telescopic rods 17 is electrically connected to the controller.
[0054] The drive components all include a dual-axis motor 24 bolted inside the housing 1. One output shaft of the dual-axis motor 24 is coaxially keyed to the drive gear 19, and the other output shaft of the dual-axis motor 24 is coaxially keyed to a first bevel gear 27. The first bevel gear 27 meshes with a second bevel gear 28, and the second bevel gear 28 is coaxially keyed to a first rotating shaft 29 that rotatably engages with the housing 1. One end of the first rotating shaft 29 corresponds to an electromagnetic clutch 37. In the initial state, the electromagnetic clutch 37 is de-energized, and the first rotating shaft 29 and the moving shaft 36 are in a separated state. The bottom of the first rotating shaft 29 is coaxially keyed to the first gear 25 (with...). Figure 7 As shown), the first gear 25 meshes with the second gear 26; both dual-axis motors 24 are electrically connected to the controller.
[0055] Each clamping assembly includes a third gear meshing with the second gear 26. The third gear is coaxially keyed to a second rotating shaft 30 that rotatably engages with the interior of the moving block 7. The second rotating shaft 30 is threadedly connected to a nut seat 31, forming a ball screw structure. A push rod 22 is screwed to the bottom end of the nut seat 31. Figure 11 As shown); the surface of the movable block 7 has two clamping through holes 11 corresponding to the fixed port 6, and the inner surface of each clamping through hole 11 is lined with a metal layer (such as copper, iron, etc.) to facilitate electrical connection when it comes into contact with the subsequent contact assembly, so that the two broken wires form a complete circuit; the inside of the movable block 7 has two clamping grooves corresponding to the clamping through holes 11 respectively; the bottom end of the push rod 22 extends through the movable block 7 into the clamping groove and is integrally formed with a clamping recess 23, and the clamping recess 23 is preferably made of insulating rubber to ensure the safety of the device; the groove of the clamping recess 23 has a semi-elliptical structure; the surface of the groove of the clamping recess 23 is fixedly connected with a rubber layer, and a pressure sensor is bonded to the connection between the clamping recess 23 and the rubber layer; the pressure sensors are all electrically connected to the controller.
[0056] Meanwhile, an isolation plate 33 is screwed to the side of the housing 1 near the limiting ring 8, and the isolation plate 33 is located between the two limiting rings 8. The isolation plate 33 divides the travel path area of the two broken wires, reducing the possibility of the two broken wires crossing and entering the clamping through hole 11, interfering with the subsequent stripping process, that is, it plays a certain guiding role and speeds up the efficiency of the two broken wire ends entering the clamping through hole 11. At the same time, the isolation plate 33 is preferably made of insulating material such as plastic or rubber to improve safety, and it can also reduce the electrical connection when some branches of the two wires come into contact with the isolation plate 33, further improving safety, and also enabling the device to start normal switching function; two support frames 21 corresponding to the clamping through hole 11 are screwed to both sides of the inner wall of the housing 1 along the length direction. The fixing port 6, the limiting ring 8, the support frame 21 and the clamping through hole 11 in the same transverse axis are all located on the same horizontal line (with Figure 2 , Figure 4 and Figure 5As shown), the two broken wires are further positioned and guided to quickly enter the clamping through hole 11. At the same time, it is ensured that the support frame 21 can keep the wire or cable stable during the clamping process, preventing it from deforming or moving due to uneven force, which helps to improve the clamping effect and further improve the efficiency of positioning the broken wire head into the clamping through hole 11.
[0057] The contact assembly includes a support plate 10 fixedly connected to the switch assembly. Two copper contact posts 9 are integrally formed at the left end of the support plate 10, each corresponding to a clamping through hole 11. Figure 4 As shown in the figure, both contact posts 9 are cylindrical boss structures, which ensures that they can enter the clamping through hole 11 and also make as much contact as possible with its inner surface, thereby improving the stability and reliability of electrical contact.
[0058] The switch assembly includes a self-locking button 4 embedded on the right side of the housing 1 (with... Figure 1 As shown), the self-locking button 4 extends through the housing 1 into the interior of the housing 1 and is screwed to the support plate 10, and the self-locking button 4 slides in cooperation with the housing 1.
[0059] The switch assembly also includes an indicator light 32 screwed onto the safety cover 2. The input and output terminals of the indicator light 32 are electrically connected to a contact post 9 and the input terminal of the self-locking button 4, respectively. The output terminal of the self-locking button 4 is electrically connected to another contact post 9.
[0060] The specific implementation process is as follows: First, the two broken wires are fed into the housing 1 through the two fixed ports 6 respectively. Since the fixed ports 6, the limiting ring 8, the support frame 21 and the clamping through hole 11 correspond to each other, that is, the central axes of the four coincide, the two broken wires can pass through the rotating ring 16, the limiting ring 8 and the support frame 21 in sequence, and finally enter the clamping through hole 11. Then, the controller starts the first telescopic rod 14 output part to extend, so that the fixed plate 15 on the first telescopic rod 14 output part squeezes and fixes the broken wires. After the fixation is completed, the dual-axis motor 24 is started. The two output ends of the dual-axis motor 24 drive the drive gear 19 and the first bevel gear 27 to rotate respectively.
[0061] When the drive gear 19 rotates, the rotating ring 16 meshes with both the drive gear 19 and the driven gear 20, and slides with the annular groove on the limiting ring 8. This causes the rotating ring 16 to rotate around its central axis, causing the cutting blade 18 on its inner wall to revolve. Simultaneously, the controller extends the output of the second telescopic rod 17, bringing the cutting blade 18 into contact with the broken wire casing, thus cutting the casing. After cutting, the second telescopic rod 17 retracts to avoid affecting subsequent processes. Furthermore, the controller provides selection parameters for different diameter wires or cables (the model number is usually printed on the surface of the wire or cable casing; refer to these parameters for settings) to quickly complete wire disconnection and switch settings. The user only needs to select the corresponding diameter or model, and the controller automatically sets the extension distance of the first telescopic rod 14 and the second telescopic rod 17, thereby improving the fixing and cutting effect.
[0062] When the first bevel gear 27 rotates, it drives the second bevel gear 28, which meshes with it, to rotate. The second bevel gear 28 then drives the first rotating shaft 29, which in turn drives the first gear 25, which is coaxially fixedly connected to it. The first gear 25 meshes with the second gear 26, and the second gear 26 is coaxially keyed to the second rotating shaft 30. The second rotating shaft 30 is also rotatably engaged with the moving block 7. Through a series of transmissions, the second rotating shaft 30 will rotate. Since the second rotating shaft 30 and the nut seat 31 form a ball screw structure, the second rotating shaft... The rotation of 30 is converted into linear motion of the nut seat 31, which in turn drives the push rod 22 and the clamping recess 23 to move closer to the broken wire. Since the groove of the clamping recess 23 is semi-elliptical, as the clamping recess 23 descends, the surface of the groove of the clamping recess 23 will gradually press against the surface of the broken wire for fixation. At the same time, the pressure sensor on the surface of the groove can monitor the clamping force of the clamping recess 23 on the wire or cable in real time and feed the signal back to the controller, so that the user or controller can understand the clamping status in time and make adjustments as needed to ensure that the clamping force is appropriate. Furthermore, during the shell peeling process, due to the movement of the moving block 7, the second gear 26 will gradually disengage from the first gear 25, causing the second gear 26 to rotate to a certain extent, which in turn causes the nut seat 31 to move downward a certain distance again, providing secondary clamping for the broken wire and improving the stability of the cut shell peeling.
[0063] After completing the shell cutting step, the controller energizes the two electromagnetic clutches 37, causing the two first rotating shafts 29 and the two movable rotating shafts 36 to be coaxially connected one-to-one, and starts the two dual-axis motors 24 (causing the first rotating shafts 19 to rotate). The rotation of the first rotating shafts 19 then drives the movable rotating shafts 36 to rotate synchronously. The movable rotating shafts 36 drive the second movable bevel gear 35 to rotate, which in turn drives the first movable bevel gear 34 meshing with it to rotate. This causes the first movable bevel gear 34 to drive the two threaded rods 13 to rotate synchronously. Due to the threaded connection between the movable block 7 and the threaded rods 13, and the limiting effect of the movable groove 12 on the movable block 7, the movable block 7 and the threaded rods 13 form a rolling motion. The ball screw structure causes the moving block 7 to move linearly as the threaded rod 13 rotates, gradually approaching the support plate 10. This allows the two contact pins 9 to enter the corresponding clamping through holes 11, pushing out the peeled outer shell. Then, the dual-axis motor 24 reverses, causing the moving block 7 to reset. Since the broken outer shell has been peeled off, its diameter will decrease, allowing it to quickly re-enter the clamping through hole 11 when the moving block 7 resets. At this point, the broken wire that has been peeled off the outer shell needs to be clamped and fixed again. Therefore, the electromagnetic clutch 37 needs to be de-energized first, separating the first rotating shaft 29 and the moving rotating shaft 36. After that, the dual-axis motor 24 is restarted, causing the clamping recess 23 to descend and clamp the wire or cable whose outer shell has been peeled off. Then, when it is necessary to disconnect the wires to reconnect them, the self-locking button 4 can be pressed to push the support plate 10 closer to the moving block 7. During the approach, the two contact posts 9 enter the corresponding clamping through holes 11 and contact their inner walls. Since the contact posts 9 and the inner walls of the clamping through holes 11 are all made of conductive materials, the two disconnected wires will form a circuit. This can be checked by the indicator light 32 on the safety cover 2 to determine whether the circuit is in a closed or open state, thus making circuit management and fault diagnosis more convenient. When it is necessary to disconnect the circuit, the self-locking button 4 can be pressed again to reset it, so that the support plate 10 moves away from the moving block 7, thereby disconnecting the circuit.
[0064] Example 2:
[0065] The difference from Example 1 is that, as Figure 1 As shown, several rubber pads 3 are adhered to the bottom of the box 1. The rubber pads 3 provide good insulation and can effectively isolate the electrical connection between the box 1 and the ground. When the self-locking button 4 is pressed, and the two contact posts 9 are electrically connected to the two broken wires respectively, an electrical circuit is formed inside the box 1. The rubber pads 3 can prevent current from leaking to the ground through the bottom of the box 1, thereby providing an extra layer of insulation protection, reducing electric shock accidents and ensuring personnel safety.
[0066] Example 3:
[0067] The difference from Example 2 is that, as Figure 2As shown, the bottom of the housing 1 has a discharge port that communicates with the interior of the housing 1 to avoid interfering with the fixing and cutting of broken wires during operation. The discharge port can be rectangular, circular, or other shapes suitable for debris discharge. A baffle 5 is hinged to the bottom of the housing 1 to control the opening and closing of the discharge port. When a large amount of stripped wire sheaths and other debris accumulates inside the housing 1, the debris can be cleaned by opening the baffle 5. First, ensure that the equipment has stopped running and the power is disconnected. Then, open the baffle 5 to allow the debris to be discharged from the discharge port. During the cleaning process, appropriate tools can be used to assist in the cleaning. After cleaning, close the baffle 5 and re-secure it.
[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
