Description

Technical Field

[0001] The invention relates to the technical field of emergency power repair, and in particular to a line-break emergency temporary docking power supply device for a distribution line switch. Background Art

[0002] Distribution lines are an important part of the power system and are responsible for transmitting electricity from substations to users. However, in actual operation, distribution lines may face various challenges, such as bad weather, external damage, aging equipment, etc., which may cause line disconnection, thus affecting the reliability and stability of power supply. When a distribution line is disconnected, emergency treatment is required in a timely manner to ensure the continuity and stability of power supply. The traditional way of dealing with line disconnection usually requires cutting off the power supply in the area where the line is disconnected, and removing all overhead wires near the line disconnection point to the ground, and using joint pipes for crimping and connection. This method is inconvenient to operate, time-consuming, and requires professional equipment and personnel, which brings many inconveniences to residents and businesses.

[0003] In summary, the present invention proposes a power supply device for emergency temporary connection of a power distribution line switch in case of line break, which simplifies the operation process, reduces the difficulty of operation and speeds up the efficiency of safe and efficient connection of line break. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a power supply device for emergency temporary docking of line breaks for distribution line switches. Through the cooperation among the cutting component, the fixing component, the clamping component and the contact component, the operation process of emergency temporary docking of line breaks is simplified, the operation difficulty is reduced, and the efficiency of safe and efficient docking of line breaks is accelerated.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a power supply device for a power distribution line switch for a line disconnection emergency temporary docking, comprising a box and a controller, a safety cover for sealing the box is hingedly connected to the top of the box, a switch assembly for controlling the connection of two broken lines is installed on one side of the box, and two fixing assemblies for respectively fixing the two broken lines are symmetrically installed on the other side of the box, two cutting assemblies for cutting the outer casing of the wires are installed inside the box, and the cutting assemblies correspond to the fixing assemblies one by one, movable grooves are opened on both sides of the inner wall of the box, and threaded rods that cooperate with the rotation of the box are arranged in the movable grooves, and one end of the threaded rods is coaxially fixedly connected to a first movable bevel gear, and the first movable bevel gear is meshed with a second movable bevel gear, and the second movable bevel gear A moving shaft that is coaxially fixedly connected to the box body for rotation is provided, and an electromagnetic clutch that is electrically connected to the controller is fixedly connected to one end of the moving shaft; a moving block that is threadedly connected to the threaded rod is provided inside the box body, and a clamping assembly for clamping the stripped part of the wire is symmetrically provided inside the moving block along the length direction of the moving block, and a driving assembly for driving the clamping assembly to clamp the wire and the cutting assembly to cut the wire casing is symmetrically installed inside the box body, and the driving assembly corresponds to the electromagnetic clutch, and a contact assembly for cleaning the stripped wire casing and driven by the switch assembly to connect the two broken wires is provided inside the box body, and one side of the contact assembly is fixedly connected to the switch assembly; the driving assembly, the clamping assembly, the fixing assembly and the switch assembly are all electrically connected to the controller.

[0006] Principle of the basic scheme: The two broken wires extending into the box body are initially fixed by the fixing component to reduce the possibility of their rotation with the rotation of the cutting component when the broken wire shell is cut later; the cutting component is synchronously driven to rotate and the clamping component is linearly moved by the driving component, so that the part of the shell at the broken part of the wire is separated from the overall shell by the cutting component, and the separated shell is clamped by the clamping component at the same time, and then the closing of the driving component and the moving shaft are controlled by the electromagnetic clutch to realize the synchronous rotation of the threaded rod with the movement of the driving component, so that the moving block moves axially along the threaded rod to strip the separated part of the shell from the wire, and when the moving block moves the contact assembly, the stripped shell is cleaned out of the clamping assembly by the contact assembly, and then the moving block is reset, and the part of the shell that has been stripped is clamped again by the clamping assembly; then the contact assembly is controlled to contact or not contact the clamping assembly by opening or closing the switch assembly, thereby completing the docking of the broken wire and the switching function.

[0007] The above scheme has the following beneficial effects: 1. The fixing component in this solution ensures the stability of the wire during the cutting process, avoiding inaccurate cutting or damage to other parts caused by the shaking of the wire. It also ensures that the wire is firmly fixed inside the box after the subsequent docking, so as to facilitate safe and efficient switching. In addition, the driving component synchronously drives the cutting component and the clamping component, so that when the wire casing is cut, both ends are respectively fixed by the clamping component and the fixing component, thereby reducing the possibility of the cutting component slipping, further improving the cutting efficiency, and speeding up the overall rate of the wire docking. At the same time, this also makes the stripping and clamping operations of the wire casing more accurate and efficient.

[0008] 2. This solution achieves smooth movement of the moving block through the cooperation of the drive assembly and the threaded rod, so that the stripped wire casing can be accurately cleaned out of the clamping assembly, which not only improves the accuracy of the operation, but also reduces the risk of equipment damage or personal injury caused by improper operation. At the same time, the design of the double threaded rod makes the moving block more stable during movement and less prone to offset or shaking. In addition, the design of the double threaded rod can also disperse the load and reduce the force on a single threaded rod, thereby extending the service life.

[0009] 3. The design of the contact assembly and switch assembly in this solution makes the connection and switch operation of the disconnected wire more flexible and reliable. By controlling the contact and non-contact between the contact assembly and the clamping assembly, the connection and disconnection of the disconnected wire can be safely and quickly realized to play the role of a switch, thereby meeting different power supply requirements.

[0010] 4. Compared with the manual or traditional mechanical docking disconnection method in the prior art, the disconnection emergency temporary docking power supply device of this solution realizes automatic operation, greatly improving work efficiency and safety. The operation of each component is uniformly controlled by the controller, reducing manual intervention, and reducing the difficulty and complexity of operation.

[0011] 5. This solution uses a driving assembly to synchronously drive the cutting assembly and the clamping assembly, achieving fast and accurate cutting and clamping operations, greatly shortening the time for handling broken wires. At the same time, an electromagnetic clutch is used to control the connection between the moving shaft and the driving assembly. When the driving assembly is connected to the moving shaft, the threaded rod can be controlled to rotate through the driving assembly to control the movement of the moving block along the threaded rod. Therefore, according to the processing flow of the broken wire, the same driving assembly is used to complete different processing actions for the broken wire, so as to reduce the overall weight of the device, facilitate carrying, and quickly arrive at the emergency treatment site for the broken wire docking processing.

[0012] Furthermore, the fixing components all include a fixing port fixed to the surface of the box and connected to the interior of the box, and inside the fixing port there are a plurality of first telescopic rods in a circular array along the circumference of the inner wall, and the output parts of the first telescopic rods are all fixedly connected to an arc-shaped fixing plate, and the first telescopic rods are all electrically connected to the controller.

[0013] Beneficial effects: Through the telescopic function of the first telescopic rod, the position of the arc-shaped fixing plate can be flexibly adjusted to adapt to wires or cables of different diameters, thereby increasing the scope of application of the device, and by accurately controlling the telescopic length and speed of the first telescopic rod, it can be ensured that the wires or cables are quickly and accurately positioned to the correct position during the docking process, which helps to improve docking efficiency and shorten fault recovery time. In addition, the design of the arc-shaped fixing plate can closely fit the outer surface of the wire or cable, provide stable support and fixation, and help prevent the wire or cable from moving or falling off during the subsequent cutting and stripping of the shell and the docking of the contact assembly with the clamping assembly, thereby improving the safety and reliability of the entire device.

[0014] Furthermore, the cutting components include a limiting ring fixed to the inner wall of the box body and corresponding to the fixed port, the limiting ring is provided with an annular groove, the annular groove is slidably matched with a rotating ring, a plurality of second telescopic rods are arranged in a circular array along the circumference of the inner wall of the rotating ring, the output parts of the second telescopic rods are fixedly connected with cutting blades, a driving gear and a driven gear are meshed on the outer surface of the rotating ring, the driving gear and the driven gear are both located inside the box body and rotatably connected to the box body; the second telescopic rods are electrically connected to the controller.

[0015] Beneficial effects: Through the telescopic function of the second telescopic rod, the position of the cutting blade can be accurately adjusted to ensure accurate and rapid cutting of wires or cables, improve cutting accuracy and efficiency, reduce losses caused by improper cutting, and realize automatic cutting of wire or cable casings of different diameters. The sliding fit design of the rotating ring and the annular groove, as well as the meshing transmission of the driving gear and the driven gear, ensure the stability and reliability of the cutting assembly during the cutting process.

[0016] Furthermore, the driving components include a dual-axis motor arranged inside the casing, one output shaft of the dual-axis motor is coaxially fixedly connected to the driving gear, the other output shaft of the dual-axis motor is coaxially fixedly connected to the first bevel gear, the first bevel gear is meshed with the second bevel gear, the second bevel gear is coaxially fixedly connected to the first rotating shaft that cooperates with the casing for rotation, one end of the first rotating shaft corresponds to the electromagnetic clutch, the bottom of the first rotating shaft is coaxially fixedly connected to the first gear, and the first gear is meshed with the second gear; the dual-axis motors are electrically connected to the controller.

[0017] Beneficial effects: The dual-axis motor, as a driving source, can provide power output in two directions at the same time, so that power can be transmitted to the clamping assembly and the rotating ring at the same time, so that the clamping and cutting processes are carried out synchronously to speed up the docking efficiency. At the same time, when the rotating ring drives the cutting blade to rotate to cut the broken wire shell, the synchronous clamping of the clamping assembly will further stabilize the broken wire, thereby further improving the cutting efficiency and quality, and then improving the integrity of the subsequent shell peeling.

[0018] Furthermore, the clamping assemblies include a third gear meshing with the second gear, the third gear is coaxially fixedly connected with a second rotating shaft that rotates with the inside of the moving block; the second rotating shaft is threadedly connected with a nut seat, the second rotating shaft and the nut seat form a ball screw structure, and the bottom end of the nut seat is fixedly connected with a push rod; two clamping through holes corresponding to the fixed mouth are opened on the surface of the moving block, and two clamping grooves corresponding to the clamping through holes are opened inside the moving block; the bottom end of the push rod extends through the moving block into the clamping groove and is fixedly connected with a clamping recessed block, and the recessed groove of the clamping recessed block is a semi-elliptical structure; the recessed surface of the clamping recessed block is fixedly connected with a rubber layer, and a pressure sensor is provided at the connection between the clamping recessed block and the rubber layer; the pressure sensors are electrically connected to the controller.

[0019] Beneficial effects: Through the meshing transmission of the second gear and the third gear, and the application of the ball screw structure, precise control of the push rod and the clamping block is achieved, so that adaptive adjustment can be made according to different wire or cable sizes to ensure moderate clamping force and avoid damage to the wire or cable. The groove of the clamping block is designed as a semi-elliptical structure, which can better adapt to the shape of the wire or cable and ensure the uniformity and reliability of clamping. At the same time, the semi-elliptical structure also helps to reduce the extrusion and deformation of the wire or cable during the clamping process. The provision of the rubber layer can increase the friction between the clamping block and the wire or cable and improve the stability of the clamping effect. At the same time, the rubber layer can also play a buffering role to reduce the wear and damage to the wire or cable during the clamping process.

[0020] The application of pressure sensors can monitor the clamping force of the clamping block on the wire or cable in real time and feed back the signal 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 moderate. The design of the clamping assembly improves the safety and reliability of the entire device by accurately controlling the clamping force and monitoring the clamping status in real time.

[0021] Furthermore, an isolation plate is installed on one side of the box body close to 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 body in the length direction.

[0022] Beneficial effects: The design of the isolation plate can divide the movement space of the two broken wires, so that the two broken wire heads can be quickly positioned in the corresponding clamping through holes, and at the same time, it can also reduce the possibility of direct contact between the two stripped wire segments during the docking process, further improving safety. The setting of two support frames corresponding to the clamping through holes provides additional support and fixation for the wires or cables. During the clamping process, the support frames can ensure that the wires or cables remain stable and prevent them from being deformed or moved due to uneven force, which helps to improve the clamping effect and also improves the efficiency of positioning the broken wire heads in the clamping through holes.

[0023] Furthermore, the contact assembly includes a support plate fixedly connected to the switch assembly, and two copper contact columns are fixedly connected to one end of the support plate away from the self-locking button, and the two contact columns are cylindrical boss structures.

[0024] Beneficial effects: The copper contact column has good electrical conductivity and corrosion resistance, and can ensure a stable electrical connection when the contact column contacts the inner wall of the clamping through hole. The design of 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 through the support plate, and can move accurately with the pressing and releasing of the self-locking button, ensuring the accuracy and reliability of the contact when closing and opening, and reducing circuit failures caused by inaccurate contact position.

[0025] Furthermore, the switch assembly includes a self-locking button installed on the side of the box body away from the fixed port, the self-locking button extends through the box body to the interior of the box body and is fixedly connected to the support plate, and the self-locking button slides with the box body; it also includes an indicator light arranged on the safety cover, the input end and output end of the indicator light are respectively electrically connected to a contact column and the input end of the self-locking button, and the output end of the self-locking button is electrically connected to another contact column.

[0026] Beneficial effect: By fixedly connecting the self-locking button with the contact assembly and combining it with the circuit design of the indicator light, intuitive display and precise control of the circuit status can be achieved. Users can determine whether the circuit is in a closed or open state by observing the on and off state of the indicator light, thereby making circuit management and troubleshooting more convenient.

[0027] The self-locking button is designed to remain locked after being pressed until it is pressed again to release the lock, which helps prevent accidental closing or opening of the circuit due to misoperation or external interference, thereby improving the safety and reliability of the circuit.

[0028] Furthermore, a discharge port communicating with the interior of the box is formed at the bottom of the box, and a baffle for controlling the opening and closing of the discharge port is hingedly connected to the bottom of the box.

[0029] Beneficial effect: The baffle is connected to the box body by a hinged manner, and the discharge port can be flexibly opened or closed to achieve rapid discharge of the peeled shells, thereby avoiding the accumulation of the peeled shells inside the box body and affecting subsequent work.

[0030] Furthermore, a plurality of rubber pads are provided at the bottom of the box.

[0031] 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 box and the ground. When the broken wire inside the box is connected, the rubber pad can prevent the current from leaking to the ground through the bottom of the box, thereby providing an additional layer of insulation protection and further improving the safety of the device.

[0044] At the same time, an isolation plate 33 is screwed to one side of the box body 1 near the limit ring 8, and the isolation plate 33 is located between the two limit rings 8. The isolation plate 33 divides the travel route area of ​​the two broken wires, reducing the possibility of the two broken wires entering the clamping through hole 11 after crossing, interfering with the subsequent stripping process, that is, playing a certain guiding role, speeding up the efficiency of the two broken wire heads entering the clamping through hole 11. At the same time, the isolation plate 33 is preferably made of insulating materials such as plastic or rubber to improve safety. At the same time, it can also reduce the electrical connection that occurs when some branches of the two subsequent wires contact the isolation plate 33, further improving safety, and at the same time enabling the device to start normal switching function; two support frames 21 corresponding to the clamping through holes 11 are screwed to both sides of the inner wall of the box body 1 in the length direction, and the fixing port 6, the limit 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.

[0048] The specific implementation process is as follows: first, the two broken wires are respectively sent into the box body 1 from the two fixing ports 6. Since the fixing port 6, the limit 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 limit ring 8 and the support frame 21 in sequence, and finally enter the clamping through hole 11, and then the controller is used to start the output part of the first telescopic rod 14 to extend, so that the fixing plate 15 on the output part of the first telescopic rod 14 squeezes and fixes the broken wires; after the fixation is completed, the dual-axis motor 24 is started, and the two output ends of the dual-axis motor 24 respectively drive the driving gear 19 and the first bevel gear 27 to rotate.

[0049] When the driving gear 19 rotates, the rotating ring 16 is meshed with the driving gear 19 and the driven gear 20, and the rotating ring 16 is slidably matched with the annular groove on the limiting ring 8, which will drive the rotating ring 16 to rotate around its own central axis, and then the cutting blade 18 located on its inner wall will revolve. At the same time, the controller controls the output part of the second telescopic rod 17 to extend, so that the cutting blade 18 contacts the outer shell of the broken wire, thereby cutting the outer shell of the broken wire, and the second telescopic rod 17 retracts after the cutting is completed to avoid affecting the subsequent process. And the controller sets corresponding selection parameters for users to choose according to wires or cables of different diameters (generally, the model will be printed on the surface of the outer shell of the wire or cable, which can be directly referred to the setting) to quickly complete the docking and switch setting of the broken wire. 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 effects.

[0050] When the first bevel gear 27 rotates, it will drive the second bevel gear 28 meshing with it to rotate, and then the second bevel gear 28 will drive the first rotating shaft 29, and the first rotating shaft 29 will drive the first gear 25 coaxially fixedly connected with it, and the first gear 25 is meshed with the second gear 26, and the second gear 26 is coaxially keyed with the second rotating shaft 30, and the second rotating shaft 30 is rotationally matched with the moving block 7, so that after a series of transmissions, the second rotating shaft 30 will rotate, and since the second rotating shaft 30 and the nut seat 31 form a ball screw structure, the second rotating shaft The rotation of the nut seat 30 is converted into the linear movement of the nut seat 31, thereby driving the push rod 22 and the clamping concave block 23 to approach the broken wire. Since the groove of the clamping concave block 23 is semi-elliptical, as the clamping concave block 23 descends, the groove surface of the clamping concave block 23 will gradually squeeze the surface of the broken wire to fix it. At the same time, through the pressure sensor on the groove surface, the clamping force of the clamping concave block 23 on the wire or cable can be monitored in real time, and the signal is fed back to the controller, so that the user or the controller can understand the clamping state in time and make adjustments as needed to ensure that the clamping force is moderate. In addition, 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, so that the second gear 26 rotates to a certain extent, and then the nut seat 31 moves downward a certain distance again, and the broken wire is clamped for the second time, which improves the stability of the cut shell when it is peeled.

[0051] After the step of cutting the shell is completed, the controller controls the two electromagnetic clutches 37 to be energized, so that the two first rotating shafts 29 and the two moving rotating shafts 36 are coaxially connected one by one, and the two dual-axis motors 24 are started (to rotate the first rotating shaft 19), and then when the first rotating shaft 19 rotates, the moving rotating shaft 36 will be driven to rotate synchronously, and the second moving bevel gear 35 will drive the first moving bevel gear 34 meshing with it to rotate, so that the first moving bevel gear 34 drives the two threaded rods 13 to rotate synchronously respectively. Since the moving block 7 and the threaded rod 13 are threadedly connected and the moving groove 12 has a limiting effect on the moving block 7, the moving block 7 and the threaded rod 13 form a rolling contact. The ball screw structure, as the threaded rod 13 rotates, the moving block 7 will move in a straight line, gradually approaching the support plate 10, so that the two contact columns 9 respectively enter the corresponding clamping holes 11, and push out the stripped shell therein, and then the double-axis motor 24 reverses to reset the moving block 7. Since the broken shell is stripped, its diameter will be reduced, so that when the moving block 7 is reset, it can quickly re-enter the clamping hole 11. At this time, it is necessary to clamp and fix the broken wire of the stripped shell again, so it is necessary to first cut off the power of the electromagnetic clutch 37 to separate the first rotating shaft 29 and the moving rotating shaft 36, and then start the double-axis motor 24 again to make the clamping recess 23 descend to clamp the wire or cable with the shell stripped. Then, when the line needs to be disconnected for connection, the self-locking button 4 can be pressed to push the support plate 10 close to the moving block 7, and during the approaching process, the two contact posts 9 respectively enter the corresponding clamping through holes 11 and contact the inner walls thereof. Since the contact posts 9 and the inner walls of the clamping through holes 11 are both made of conductive materials, the two broken lines will form a loop, and the indicator light 32 on the safety cover 2 can be used to check whether the circuit is in a closed or disconnected state, thereby making it more convenient to manage the circuit and troubleshoot. When the loop needs to be disconnected, the self-locking button 4 is pressed again to reset it, so that the support plate 10 is away from the moving block 7, thereby disconnecting the loop.

[0052] Embodiment 2:

[0053] The difference from Example 1 is that Figure 1 As shown, a plurality of rubber pads 3 are bonded to the bottom of the box 1. The rubber pads 3 are used for good insulation and can effectively isolate the electrical connection between the box 1 and the ground. When the self-locking button 4 is pressed to electrically connect the two contact posts 9 to the two broken wires, an electrical circuit is formed inside the box 1. The rubber pads 3 can prevent the current from leaking to the ground through the bottom of the box 1, thereby providing an additional layer of insulation protection, reducing electric shock accidents and ensuring personnel safety.

[0054] Embodiment 3:

[0055] The difference from Example 2 is that Figure 2As shown, the bottom of the box 1 is provided with a discharge port connected to the inside of the box 1 to avoid interference with the fixing and cutting of the broken wires during operation. The shape of the discharge port can be rectangular, circular or other shapes suitable for the discharge of debris. The bottom of the box 1 is hinged with a baffle 5 for controlling the opening and closing of the discharge port. When a large amount of stripped wire casings and other debris accumulates inside the box 1, the baffle 5 can be opened to clean the debris. First, make sure that the equipment has stopped running and disconnected the power supply, 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 cleaning. After cleaning, close the baffle 5 and re-secure it.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
