Description
Technical Field
[0001] This invention relates to the field of low-voltage integrated distribution box technology, specifically to a low-voltage integrated distribution box with an emergency power supply quick-connect device and its usage method. Background Technology
[0002] Low-voltage integrated distribution boxes are the core terminal equipment of low-voltage power distribution systems, widely used in residential communities, industrial parks, municipal engineering projects, rail transit, commercial complexes, hospitals, schools, and outdoor work scenarios. They undertake core functions such as low-voltage power distribution, metering, protection, control, and monitoring, serving as a "bridge" connecting the power grid and power-consuming terminals. Their operational stability and emergency response capabilities directly affect the safe and reliable operation of various electrical equipment. Especially for critical loads such as fire protection facilities, security monitoring, emergency lighting, core production equipment, and medical emergency equipment, the emergency power supply guarantee capability of low-voltage integrated distribution boxes is crucial to preventing secondary safety accidents caused by sudden power outages and reducing economic losses.
[0003] Currently, traditional low-voltage integrated distribution boxes do not integrate dedicated emergency power supply quick-connect devices. Their emergency power supply mainly relies on manual wiring operations. Emergency wiring requires opening the distribution box door, and operators must directly contact the live terminals and wires inside the distribution box. If operators do not take proper insulation precautions, or if the internal wiring layout of the distribution box is chaotic and live components are exposed, electric shock accidents can easily occur, threatening the personal safety of operators. In traditional emergency power supply methods, there is no interlocking protection structure between the main power supply circuit and the emergency power supply circuit. If the main power supply is restored to normal and the operator does not disconnect the emergency power supply circuit in time, a "backfeeding" phenomenon will occur—that is, the power of the emergency generator is transmitted back to the grid. This will not only damage the emergency generator and the internal components of the distribution box, but may also threaten the personal safety of grid maintenance personnel and cause secondary grid faults.
[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention
[0005] The purpose of this invention is to provide a low-voltage integrated distribution box with an emergency power supply quick-connect device and a method of use, so as to solve the problems mentioned in the background art.

The side wall of the abutment block is designed to be inclined, and the inclined surface of the abutment block abuts against the protruding rod.
[0011] Preferably, the adjusting ring and the connecting ring are fixed together by a connecting rod, and the connecting ring and the rotating ring are fixed together by a connecting rod; the side wall protrusion of the adjusting ring is limited to slide within the groove on the inner wall of the groove at the side end of the power supply mounting compartment, the contact rod has a groove inside, and the connecting ring has a protrusion fixed on the side near the contact rod, and the protrusion is limited to slide within the groove of the contact rod.
[0012] Preferably, the release mechanism includes a mounting platform fixed within a notch on the surface of the power supply mounting compartment. A pressing rod is slidably positioned inside the mounting platform, and a squeezing platform is mounted on the surface of the pressing rod. A limiting block is mounted on one end of the pressing rod inside the mounting platform, and a limiting block is slidably positioned on the surface of the pressing rod. Symmetrically arranged insert blocks are installed in two sets of notches inside the mounting platform. A moving rod is mounted on one end of the squeezing platform near the bottom of the notch in the power supply mounting compartment, and a sleeve is fitted on the surface of the moving rod. A rotating block is rotatably connected inside the notch in the power supply mounting compartment. A first oil tank is installed on the inner wall of the notch in the power supply mounting compartment, and a first piston rod is slidably positioned inside the first oil tank. A second oil tank is installed inside the insert, and a second piston rod is slidably positioned inside the second oil tank. The end of the second piston rod is connected to a moving ring.
[0013] Preferably, both the extrusion platform and the limiting block are frustum designs; the diameter of the extrusion platform is larger than that of the limiting block, and the inclined surfaces of the limiting block and the extrusion platform are symmetrically designed; a spring is installed at the end of the insert block away from the interior of the mounting platform, and the other end of the spring is connected to the side wall of the power supply mounting compartment notch; the end of the insert block closer to the interior of the mounting platform is inclined.

[0015] Preferably, the method includes the following steps:
[0016] S1: Remove the end cover of the power installation compartment, place the emergency power cord in the emergency plug interface, press the pressing rod to push the squeezing table to move, drive the plug block to lock, and at the same time, the linkage components drive the moving ring to complete the lifting, clamping and insertion of the emergency power cord into the interface.
[0017] S2: After the rotating block rotates, the convex strip disengages from the first piston rod, the first oil tank resets, causing the moving ring to move in the opposite direction, the old power cord is pulled out, the adjusting ring and other actions are reversed, and the clamping and lifting are released.
[0018] S3: Press the lever again and release it to reset it. The plug will not be locked, releasing the emergency power cord and completing the connection and locking of the regular power cord, thus switching the emergency power back to the regular power.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] 1. This invention, through its plug-in locking mechanism, enables automatic plug-in of power cords in emergency and conventional plug-in interfaces, and clamps and locks the plugged-in power cords. The automatic alignment and plug-in of power cords in the emergency and conventional plug-in interfaces significantly shortens emergency power supply time. The mechanical locking mechanism provides stable clamping force, counteracting the tension caused by external forces, equipment vibration, and cable weight, preventing the power cord from loosening from the plug-in interface. After plugging, the mechanism automatically clamps and locks the power cord, ensuring a tight and secure connection between the power cord and the plug-in interface. This achieves an integrated automated "plug-in-lock" process, greatly improving the efficiency and stability of power supply switching.
[0021] 2. This invention, through its designed release mechanism, automatically connects and locks the cable within the emergency connector when a power cord is plugged into it, while simultaneously releasing and unlocking the cable within the regular power connector. Similarly, when the cable within the regular connector is plugged in and locked, the cable within the emergency connector is released and unlocked. This release mechanism, through mechanical linkage, achieves synchronized automation of "plug-in-lock" and "release-unlock." Operators only need to perform the single action of "plugging in the power cord" to automatically complete "target connector locking + non-target connector unlocking," eliminating the need for manual disassembly and unlocking of the cables between the regular and emergency connectors. This simplifies the dual-connection switching process from "disassembly-connection-tightening" to a single plug-in step, significantly reducing operation time. It is particularly suitable for emergency scenarios involving sudden failures, eliminating the need for repeated disassembly and reassembly of regular and emergency cables and enabling rapid power switching. The release mechanism, through physical interlocking, forces only one connector to be plugged in and locked at a time, completely preventing backfeeding and protecting the safety of emergency power generation equipment, the power grid, and the user terminals.

Detailed Implementation
[0034] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.
[0035] Please see Figures 1-11This invention provides a technical solution: a low-voltage integrated distribution box with an emergency power supply quick-connect device and its usage method, comprising a distribution box body 1, a power installation compartment 2 installed at the bottom of the distribution box body 1, a cover plate bolted to one end of the power installation compartment 2 located on the side wall of the distribution box body 1, and two plug-in interfaces 3 installed on the bottom wall of the groove at one end of the side wall of the power installation compartment 2, one for emergency use and the other for regular use. Both plug-in interfaces 3 have internal moving rings 4 equipped with plug-in locking mechanisms; one set of plug-in locking mechanisms is in a locked state. Another set of plug-in locking mechanisms is in the released state. A movable ring 4 is limited and slidable inside the plug-in interface 3. A placement compartment 5 is installed at the end of the inner wall of the movable ring 4 away from the power installation compartment 2, and a restriction compartment 6 is installed at the end of the movable ring 4 near the power installation compartment 2. A sliding groove is opened on the inner wall of the groove on the side end of the plug-in interface 3. The section of the sliding groove near the power installation compartment 2 is vertical, and the section away from the power installation compartment 2 is inclined. The placement compartment 5 and the restriction compartment 6 are installed on the inner wall of the movable ring 4. A plug-in locking mechanism is set inside the movable ring 4. An installation platform 8 is installed inside the power installation compartment 2. A release mechanism is set inside the installation platform 8.
[0036] In one embodiment of the present invention, the insertion locking mechanism includes two placement plates 701 that slide within the placement chamber 5. One end of each placement plate 701 is connected to a protruding rod inside the placement chamber 5. A spring is installed on one end of the protruding rod near the placement plate 701, and the other end of the spring is connected to the inner wall of the placement chamber 5. The sidewall of the abutment block 706 is inclined, and the inclined surface of the abutment block 706 abuts against the protruding rod. An adjusting ring 702 is rotatably mounted on the end of the chamber 6 near the insertion interface 3. The adjusting ring 702 and the connecting ring 703 are fixed together by a connecting rod. The connecting ring 703 and the rotating ring 705... The two are fixed by a connecting rod; the side wall protrusion of the adjusting ring 702 slides within the groove of the inner wall of the groove at the side end of the power installation compartment 2; the inside of the contact rod 704 is provided with a groove; the connecting ring 703 has a protrusion fixed on the side near the contact rod 704, and the protrusion slides within the groove of the contact rod 704; the connecting ring 703 is rotatably connected inside the cavity of the limiting compartment 6; three contact rods 704 are rotatably connected inside the limiting compartment 6; the placing compartment 5 is rotatably connected inside; the limiting compartment 6 is rotatably connected inside; and the contact block 706 is mounted on the surface of the rotating ring 705.
[0037] As the moving ring 4 moves, it causes the side protrusion of the adjusting ring 702 to slide inside the side groove of the emergency connector 3, causing the adjusting ring 702 to rotate at the end of the limiting chamber 6. Simultaneously, the rotation of the adjusting ring 702 causes the connecting ring 703 and the rotating ring 705 to rotate together. As the rotating ring 705 rotates, it abuts against the protruding rod at the end of the placement plate 701 via the inclined surface of the abutment block 706, causing the placement plate 701 to move towards the center of the moving ring 4, thus supporting the emergency power cord. Meanwhile, as the connecting ring 703 rotates, its end protrusion slides within the groove inside the abutment rod 704, causing the three abutment rods 704 to... The rotation clamps the emergency power cord, and then the moving ring 4 continues to move, inserting the emergency power cord into the interface within the emergency connector 3. This achieves automatic connection between the emergency connector 3 and the regular connector 3, and also clamps and locks the connected power cord. The automatic alignment and connection of the power cord between the emergency connector 3 and the regular connector 3 significantly shortens the emergency power supply operation time. The mechanical locking mechanism provides stable clamping force, counteracting the tension caused by external forces, equipment vibration, and the cable's own weight, preventing the power cord from loosening from the connector 3.
[0038] In one embodiment of the present invention, the release mechanism includes a mounting platform 8 fixed within a notch on the surface of the power supply mounting compartment 2. A pressing rod 901 is slidably mounted inside the mounting platform 8. A pressing platform 902 is mounted on the surface of the pressing rod 901. A limiting block 903 is mounted at one end of the pressing rod 901 inside the mounting platform 8. The limiting block 903 is slidably mounted on the surface of the pressing rod 901. Symmetrically arranged insert blocks 904 are installed in two sets of notches inside the mounting platform 8. Both the pressing platform 902 and the limiting block 903 are frustum designs. The diameter of the pressing platform 902 is larger than that of the limiting block 903, and the inclined surfaces of the limiting block 903 and the pressing platform 902 are symmetrically designed. A spring is mounted at the end of the insert block 904 away from the interior of the mounting platform 8, and the other end of the spring is connected to the side wall of the notch in the power supply mounting compartment 2. The end of the insert block 904 near the interior of the mounting platform 8 is inclined. The pressing platform 902 is close to the power supply mounting compartment 2. A movable rod 905 is installed at one end of the bottom of the notch in compartment 2. A sleeve 906 is fitted on the surface of the movable rod 905. A spiral groove is opened inside the sleeve 906. The protrusion on the surface of the movable rod 905 slides within the spiral groove of the sleeve 906. A compression table 907 is rotatably connected inside the sleeve 906. The other end of the compression table 907 is rotatably connected to the movable rod 905. A protruding strip is installed on the side of the rotating block 908. A hose is connected between the first oil tank 909 and the second oil tank 911. A rotating block 908 is rotatably connected inside the notch in the power supply compartment 2. The first oil tank 909 is installed on the inner wall of the notch in the power supply compartment 2. A first piston rod 910 slides within the first oil tank 909. A second oil tank 911 is installed inside the insertion interface 3. A second piston rod 912 slides within the second oil tank 911. The end of the second piston rod 912 is connected to the movable ring 4.
[0039] Pressing the pressing lever 901 pushes the extrusion table 902 inside the mounting platform 8 towards the power supply mounting chamber 2. As the extrusion table 902 moves, its inclined surface continuously contacts the inclined surface of the insertion block 904, causing it to move away from the center of the mounting platform 8. When the insertion block 904 contacts the limiting block 903, it loses the resistance from the extrusion table 902, thus pushing the limiting block 903 to slide away from the extrusion table 902. Simultaneously, the rebound generated by the side spring pushes the insertion block 904 towards the center of the mounting platform 8, inserting it between the extrusion table 902 and the limiting block 903. Within the gap, locking is achieved; while the pressing table 902 moves, it drives the moving rod 905 to move together. At this time, the protrusion on the surface of the moving rod 905 slides within the spiral groove on the surface of the sleeve 906. The rotation of the sleeve 906 drives the rotating block 908 to rotate on the inner wall surface of the port inside the power installation compartment 2. The protrusion on the side of the rotating block 908 abuts against the first piston rod 910 on the other side through the rotation of the rotating block 908, causing the oil in the first oil tank 909 on the other side to be injected into the second oil tank 911 in the emergency connector 3. At this time, the oil in the second oil tank 911 in the emergency connector 3 increases, pulling the second piston rod 912. As the moving ring 4 moves toward the second oil tank 911, the rotating block 908 rotates, and its side protrusion loses contact with the first piston rod 910. At this time, the spring inside the first oil tank 909 rebounds, causing the first piston rod 910 inside the first oil tank 909 to automatically reset. The reset of the first piston rod 910 causes the oil in the second oil tank 911 inside the connector 3 to decrease, thereby pulling the second piston rod 912 to move the moving ring 4 away from the second oil tank 911. At this time, the moving ring 4 moves to pull the power cord out of the connector 3 on the other side. When the power cord is plugged into the emergency connector 3, the emergency... The cable in connector 3 is automatically plugged in and locked, while the cable in the regular power connector is simultaneously released and unlocked. When the cable in the regular connector 3 is plugged in and locked, the cable in the emergency connector 3 is released and unlocked. The release mechanism achieves synchronous automation of "plugging-locking" and "release-unlocking" through mechanical linkage. The operator only needs to complete the single action of "plugging in the power cord" to automatically complete "target interface locking + non-target interface unlocking". There is no need to manually disassemble and unlock the cables of the regular / emergency interfaces. The operation steps of switching between dual interfaces are simplified from "disassembly-connection-tightening" to one-step plugging, which greatly shortens the operation time.
[0040] As one embodiment of the present invention, the method includes the following steps:
[0041] S1: Remove the end cover of the power installation compartment 2, place the emergency power cord in the emergency plug interface 3, press the pressing rod 901 to push the squeezing table 902 to move, drive the plug block 904 to lock, and at the same time, the linkage component drives the moving ring 4 to complete the lifting, clamping and insertion of the emergency power cord into the interface.
[0042] S2: After the rotating block 908 rotates, the convex strip disengages from the first piston rod 910, the first oil tank 909 resets, causing the moving ring 4 to move in the opposite direction, the old power cord is pulled out, the adjusting ring 702 and other reverse actions are performed, and the clamping and lifting are released.
[0043] S3: Press and release the lever 901 to reset it. The plug 904 will not be locked, releasing the emergency power cord and completing the connection and locking of the regular power cord, thus switching the emergency power back to the regular power.
[0044] Working principle: When switching emergency power, first remove the cover plate from the end of the power installation compartment 2. Then, place the emergency power cord at the emergency connector 3 on the side of the power installation compartment 2. Next, press the pressing lever 901 to push the pressing table 902 inside the mounting platform 8 towards the power installation compartment 2. As the pressing table 902 moves, its inclined surface continuously contacts the inclined surface of the plug block 904, causing it to move away from the center of the mounting platform 8. When the plug block 904 contacts the limiting block 903, the plug block 904 loses the resistance from the pressing table 902. This causes the limiting block 903 to slide away from the extrusion table 902. As the insertion block 904 loses its resistance, the spring at its side pushes it towards the center of the mounting platform 8, inserting it into the gap between the extrusion table 902 and the limiting block 903, thus locking it in place. Simultaneously, the extrusion table 902 moves, causing the moving rod 905 to move as well. At this time, the protrusion on the surface of the moving rod 905 slides within the spiral groove on the surface of the sleeve 906, limiting its movement. The rotation of the sleeve 906 causes the rotating block 908 to rotate on the inner wall surface of the power supply mounting compartment 2. The side protrusion of block 908 abuts against the first piston rod 910 on the other side through the rotation of block 908, causing the oil inside the first oil tank 909 on the other side to be injected into the second oil tank 911 inside the emergency connector 3. At this time, the oil inside the second oil tank 911 inside the emergency connector 3 increases, pulling the second piston rod 912 and causing the moving ring 4 to move towards the second oil tank 911. At the same time, the moving ring 4 causes the side protrusion of the adjusting ring 702 to slide inside the side groove of the emergency connector 3, causing the adjusting ring 702 to rotate at the end of the limiting chamber 6. As the adjusting ring 702 rotates, it drives the connecting ring 703 and the rotating ring 705 to rotate together. As the rotating ring 705 rotates, it abuts against the protruding rod at the end of the placement plate 701 through the inclined surface of the abutment block 706, causing the placement plate 701 to move towards the middle of the moving ring 4, thus lifting the emergency power cord. As the connecting ring 703 rotates, it slides in the groove inside the abutment rod 704 through its end protrusion, causing the three abutment rods 704 to rotate and clamp the emergency power cord. Then the moving ring 4 continues to move and inserts the emergency power cord into the interface in the emergency plug interface 3.
[0045] As the rotating block 908 rotates, its side protrusion loses contact with the first piston rod 910. At this time, the spring inside the first oil tank 909 rebounds, causing the first piston rod 910 inside the first oil tank 909 to automatically reset. The reset of the first piston rod 910 causes the oil in the second oil tank 911 inside the plug-in interface 3 to decrease, thereby pulling the second piston rod 912 to move the moving ring 4 away from the second oil tank 911. At this time, the moving ring 4 moves and pulls the power cord out of the plug-in interface 3 on the other side. The moving ring 4 continues to move. The sliding groove on the inner wall of the plug-in interface 3 on the other side causes the adjusting ring 702 to rotate in the opposite direction. At the same time as the adjusting ring 702 rotates in the opposite direction, it causes the connecting ring 703 and the rotating ring 705 to rotate together. The reverse rotation of the connecting ring 703 causes the contact rod 704 to open and end the clamping of the power cord. The reverse rotation of the rotating ring 705 causes the placement plate 701 to move away from the center of the placement compartment 5 and lose the support of the power cord.
[0046] When switching from emergency power to regular power, continue pressing the pressing lever 901 to allow the limiting block 903 to continue pressing the inclined surface of the insertion block 904 until the insertion block 904 contacts the inclined surface of the limiting block 903. Then release the pressing lever 901. The pressing lever 901 loses its contact force and the spring generated by the compression table 907 causes the pressing lever 901 to automatically reset. At the same time as the pressing lever 901 resets, the spring generated by the side spring of the insertion block 904 continues to apply pressure to the inclined surface of the limiting block 903, causing the limiting block 903 to fit against the compression table 902. At this time, when the pressing lever 901 resets, the insertion block 904 will not be inserted into the gap between the compression table 902 and the limiting block 903 until the pressing lever 901 returns to its original position. At this time, the emergency power cord in the emergency connector 3 is released, and the power cord in the regular connector 3 is plugged in and locked.
