Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, specifically a dual-power distribution cabinet. Background Technology

[0002] Dual-power distribution cabinets are important power distribution protection devices in power supply systems, widely used in uninterrupted power supply scenarios such as industrial plants, commercial buildings, and communication equipment rooms. The equipment integrates core power distribution components such as ATS dual power supply, relays, and circuit breakers, enabling automatic switching between the main power supply and the backup power supply. It also has functions such as line overload and short circuit protection and loop linkage control, thereby ensuring the continuity of power supply to the electrical load and the safety of operation. It is an indispensable infrastructure in the field of low-voltage power distribution.

[0003] However, during long-term operation and maintenance of the distribution cabinet, the nozzles of the non-pressurized perfluorohexanone fire extinguishing device inside the cabinet are exposed for extended periods. The airflow generated by the cabinet's circulating ventilation carries dust that continuously adheres and accumulates, easily causing nozzle blockage and severely affecting the normal spraying of the extinguishing agent in the event of a fire. At the same time, the cabinet's side walls are generally equipped with open ventilation holes to meet the heat dissipation requirements of the components. If the electrical components inside the cabinet catch fire, high-temperature toxic fumes will directly overflow from the ventilation holes and spread to the surrounding area, leading to various secondary safety hazards. Furthermore, the electrical components inside the cabinet are only installed on guide rails, lacking supporting auxiliary structures. During component installation and replacement, operators must support the electrical components with one hand and tighten the screws with the other, making the operation difficult. This not only reduces assembly and maintenance efficiency but also fails to effectively guarantee the alignment accuracy of component installation. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 and Figure 7As shown, the dual-power distribution cabinet of the present invention includes a cabinet body 1, on which a power distribution component and a fire extinguishing component are provided, and a sealing structure 2 is provided on the cabinet body 1; the sealing structure 2 includes a sealing component slidably connected to the cabinet body 1, the sealing component being used to seal the heat dissipation holes, a guide component being provided on the cabinet body 1 for guiding the sealing structure 2, a limiting component being provided on the cabinet body 1, the sealing component being fixed by the limiting component, and a protective structure 5 being provided on the cabinet body 1, the limiting component and the protective structure 5 being used in conjunction.

[0023] Specifically, such as Figure 1 , Figure 7 and Figure 9 As shown, the power distribution components include a mounting bracket 8, an ATS dual power supply 9, a relay 10, and a circuit breaker 11. The mounting bracket 8 is installed on the cabinet 1. The ATS dual power supply 9 monitors the operating status of the two power supplies in real time and automatically switches between the primary and backup power supplies. The relay 10 receives control signals to realize circuit on / off switching and signal linkage transmission. The circuit breaker 11 monitors the line load parameters in real time and quickly trips to disconnect the circuit in case of overload or short-circuit faults. These three components work together to ensure continuous power supply and electrical safety in the power distribution cabinet. The ATS dual power supply 9, relay 10, and circuit breaker 11 are respectively installed on multiple crossbeams of the mounting bracket 8. The fire extinguishing components include a perfluorohexanone fire extinguishing device 7 and a control... Device 12, a non-pressurized perfluorohexanone fire extinguishing device 7, normally stores perfluorohexanone extinguishing agent in a liquid state at atmospheric pressure. After receiving the electric start signal from controller 12, the built-in electric initiator (preferably powered by 24V DC) ignites the driving agent to generate high-pressure gas that pushes the piston. When the pressure reaches 1.2MPa, the rupture disc breaks, and the extinguishing agent is sprayed out through the atomizing nozzle. Utilizing its low boiling point of 49.2℃, it rapidly vaporizes and absorbs a large amount of heat to achieve physical cooling. At the same time, it inhibits the combustion chain reaction by diluting the oxygen concentration and generating free radicals through the decomposition of fluorocarbon bonds at high temperature. The triple mechanism works together to quickly extinguish electrical fires inside cabinet 1. The cabinet 1 is equipped with perfluorohexanone fire extinguishing device 7 and controller 12.

[0024] Specifically, such as Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, the sealing assembly includes a counterweight frame 201, a sealing plate 202, and a sealing gasket 203. Two counterweight frames 201 are slidably connected to the cabinet body 1, and a sealing plate 202 is slidably connected to the counterweight frame 201. A sealing gasket 203 is fixedly connected to the sealing plate 202. The guide assembly includes a guide frame 204, a tension spring 205, a roller 206, a straight groove 207, a connecting block 208, and an inclined groove 209. Two guide frames 204 are fixedly connected to the cabinet body 1. Each counterweight frame 201 is slidably connected to two guide frames 204. A tension spring 205 is fixedly connected between the counterweight frame 201 and the guide frame 204. The counterweight frame 201 is provided with a straight groove 207. A connecting block 208 is fixedly connected to the cabinet 1. The connecting block 208 is provided with a slanted groove 209. A roller 206 is rotatably connected to the sealing plate 202. The roller 206 rolls with the straight groove 207 and the slanted groove 209. The guide frames 204 in the guide assembly are matched. The counterweight frame 201 forms a reliable sliding limit constraint, the tension spring 205 maintains the structure in a normal tension state, and the roller 206 simultaneously rolls against the inner walls of the straight groove 207 and the inclined groove 209, keeping the sealing plate 202 and the sealing gasket 203 in a retracted state, completely avoiding the heat dissipation holes on the side wall of the cabinet 1, ensuring normal air convection and exchange inside and outside the cabinet, and meeting the heat dissipation and ventilation requirements of the electrical components inside the cabinet. The limit rod 210 in the limit assembly slides stably along the guide rail 212 and forms a locking limit with the counterweight frame 201, effectively avoiding the situation where the sealing assembly is displaced due to vibration during equipment operation. The limit assembly includes the limit rod 210, the drive shaft 211 and the guide rail 212. The guide rail 212 is fixedly connected to the cabinet 1, and the limit rod 210 is slidably connected to the guide rail 212 on both sides. The two limit rods 210 are respectively locked with the two counterweight frames 201, and the drive shaft 211 is rotatably connected to the limit rod 210.

[0025] Specifically, such as Figure 7 and Figure 8 As shown, the protective structure 5 includes a rotating shaft 501 rotatably connected to the cabinet 1 and a connecting rod 502 fixedly connected to the rotating shaft 501. A protective cover 503 is fixedly connected to the connecting rod 502. The protective cover 503 is used to protect the nozzle of the perfluorohexanone fire extinguishing device 7. A rubber ring 504 is fixedly connected to the protective cover 503. The rubber ring 504 abuts against the perfluorohexanone fire extinguishing device 7. The rotating shaft 501 remains stationary, and the connecting rod 502 provides fixed support for the protective cover 503, ensuring its stable coverage of the perfluorohexanone fire extinguishing device 7. The rubber ring 504 on the outside of the nozzle of the ketone fire extinguishing device 7 and the inside of the protective cover 503 are tightly fitted to the outer wall of the device to form a closed-loop protection. This can effectively prevent dust carried by the air in the cabinet from adhering and accumulating at the nozzle position, continuously ensuring that the nozzle orifice is clean and unobstructed, and forming a continuous isolation protection for the fire extinguishing nozzle. This further improves the structural stability and durability of each component for long-term static use. Both ends of the rotating shaft 501 are provided with spiral grooves 505, and drive shafts 211 are rolled in the two spiral grooves 505 respectively.

[0026] Specifically, such as Figure 7 As shown, the rotating shaft 501 is driven to rotate by the drive structure 6. The drive structure 6 includes a gear 601 fixedly connected to the rotating shaft 501 and a rack 602 meshing with the gear 601. After receiving an electrical signal, the drive component 605 performs a telescopic operation, driving the rack 602 to slide smoothly along the guide rod 604. The rack 602 meshes with the gear 601, driving the rotating shaft 501 to rotate in a specific direction. The spiral grooves 505 at both ends of the rotating shaft 501 rotate synchronously and form a rolling fit with the drive shaft 211, synchronously pushing the limit rods 210 on both sides to slide towards each other along the guide rail 212, releasing the locking relationship between the limit rods 210 and the counterweight frame 201. A mounting base 603 is fixedly connected to the cabinet 1, and a guide rod 604 is fixedly connected to the mounting base 603. The rack 602 is slidably connected to the guide rod 604. The drive component 605 is installed on the mounting base 603, and the rack 602 is driven to slide by the drive component 605.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 9 , Figure 10 and Figure 11 As shown, the cabinet 1 is provided with a support structure 3, which includes a slide plate 301 slidably connected to the cabinet 1 and multiple slide rods 302 slidably connected to the slide plate 301. A connecting shaft 303 is rotatably connected to the slide rods 302, and a torsion spring 304 is fixedly connected between the connecting shaft 303 and the slide rods 302. A limit block 305 is fixedly connected to the connecting shaft 303. The connecting shaft 303 is rotated by a rotating block at the bottom of the connecting shaft 303. The torsion spring 304 provides a stable rotational torque to the connecting shaft 303. The connecting shaft 303 drives the limit block 305 to rotate 90 degrees inside the rotating groove 306. The pointer 309 rotates synchronously, which can intuitively determine the rotation position of the limit block 305. After rotating 90 degrees, the slide rod 302 is pulled to slide smoothly along the guide plate 307 and extend. At this time, the limit block 305 can slide synchronously along the sliding groove 308. When the slide bar 302 moves to the designated position, the limiting block 305 is exactly located in the rotating groove 306 at the other end of the slide groove 308. After the rotating block is released, the limiting block 305 is engaged with the rotating groove 306 under the action of the torsion spring 304, which restricts the slide bar 302 from sliding back. The extended slide bar 302 can provide stable support for the bottom of the electrical components, forming a reliable auxiliary support point. There is no need for manual hand support of the components throughout the process. The setting of multiple slide bars 302 can flexibly adapt to the installation and use of different numbers of power distribution components, effectively improving the neatness of the component assembly and the ease of operation in the cabinet. The slide plate 301 is provided with a rotating groove 306 and a slide groove 308 that cooperate with the limiting block 305. A pointer 309 is fixedly connected to the connecting shaft 303. A guide plate 307 is fixedly connected to the slide plate 301. The slide bar 302 is slidably connected to the guide plate 307.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, a limiting structure 4 is provided between the slide plate 301 and the cabinet 1. The limiting structure 4 includes a pull rod 401 slidably connected to the slide plate 301 and a limiting shaft 402 fixedly connected to the pull rod 401. A vertical rod 403 is fixedly connected to the cabinet 1. The slide plate 301 is slidably connected to the vertical rod 403. The vertical rod 403 is provided with multiple limiting holes 404. First, pull the pull rod 401 to compress the spring 407 and disengage the limiting shaft 402 from the limiting holes 404 on the surface of the vertical rod 403. At this time, the slide plate 301 can slide freely vertically along the vertical rod 403. After adjusting to the appropriate installation height, release the pull rod 401. The spring 407 elastically... The limit shaft 402 is reset and pushed into the corresponding limit hole 404 to lock and fix the slide plate 301, thereby effectively improving the stability of the slide plate 301. The limit shaft 402 engages with one of the limit holes 404. A connecting frame 405 is fixedly connected to the slide plate 301. The pull rod 401 is slidably connected to the connecting frame 405. A screw 406 is threadedly connected to the pull rod 401. The screw 406 is threadedly assembled with the connecting frame 405, which facilitates the disassembly, replacement and maintenance of the spring 407 in the later stage. The screw 406 is slidably connected to the connecting frame 405. The spring 407 is in contact between the pull rod 401 and the connecting frame 405.

[0029] In use, the operator first performs electrical installation work inside the dual-power distribution cabinet in an indoor assembly and maintenance environment. When assembling power distribution components such as the ATS dual power supply 9, relay 10, and circuit breaker 11, the operator first pulls the pull rod 401, causing the limit shaft 402 to compress the spring 407 and disengage from the limit hole 404 on the surface of the vertical rod 403. At this time, the slide plate 301 can slide freely vertically along the vertical rod 403. After adjusting to the appropriate installation height, the pull rod 401 is released, and the spring 407 elastically resets and pushes the limit shaft 402 into the corresponding limit hole 404, thereby locking and fixing the slide plate 301 and effectively improving the stability of the slide plate 301. The threaded assembly of the screw 406 and the connecting frame 405 facilitates the later disassembly, replacement, and maintenance of the spring 407. Subsequently, the operator rotates the connecting shaft 303 according to the number and specifications of the electrical components to be installed by rotating the connecting shaft 303 through the rotating block at the bottom of the connecting shaft 303. The torsion spring 304 is a connecting... The connecting shaft 303 provides stable rotational torque, which drives the limiting block 305 to rotate 90 degrees inside the rotating groove 306. The pointer 309 rotates synchronously, which can intuitively judge the rotation status of the limiting block 305. After rotating 90 degrees, the sliding rod 302 is pulled to slide smoothly along the guide plate 307. At this time, the limiting block 305 can slide synchronously along the sliding groove 308. When the sliding rod 302 moves to the designated position, the limiting block 305 is exactly located in the rotating groove 306 at the other end of the sliding groove 308. After releasing the rotating block, the limiting block 305 is engaged and positioned with the rotating groove 306 under the action of the torsion spring 304, which restricts the sliding rod 302 from sliding back. The extended sliding rod 302 can provide stable support for the bottom of the electrical components, forming a reliable auxiliary support point. There is no need for manual hand support of the components throughout the process. The setting of multiple sliding rods 302 can flexibly adapt to the installation and use of different numbers of power distribution components, effectively improving the neatness of the component assembly and the ease of operation in the cabinet. The dual-power distribution cabinet operates in a continuous indoor power supply environment. The ATS dual-power supply 9 monitors the operating status of both power supplies in real time and automatically switches between the primary and backup power supplies. The relay 10 receives control signals to achieve circuit on / off switching and signal linkage transmission. The circuit breaker 11 monitors line load parameters in real time and quickly trips to disconnect the circuit in case of overload or short-circuit faults. These three components work together to ensure continuous power supply and electrical safety for the distribution cabinet. During the stable operation of the power distribution components inside the cabinet 1, the guide frame 204 in the guide assembly provides reliable sliding limit constraint on the counterweight frame 201. The tension spring 205 maintains the structure in a normally tensioned state. The roller 206 simultaneously rolls against the inner walls of the straight groove 207 and the inclined groove 209, keeping the sealing plate 202 and the sealing gasket 203 in a retracted state, completely avoiding contact with the side walls of the cabinet 1. The ventilation holes ensure normal air convection and exchange inside and outside the cabinet, meeting the heat dissipation and ventilation requirements of the electrical components inside the cabinet. The limit rod 210 in the limit assembly slides stably along the guide rail 212 and engages with the counterweight frame 201 to limit the movement, effectively preventing the sealing components from shifting due to vibration during equipment operation. At the same time, the rotating shaft 501 remains stationary, and the connecting rod 502 fixes and supports the protective cover 503, so that it stably covers the outside of the nozzle of the perfluorohexanone fire extinguishing device 7. The rubber ring 504 on the inner side of the protective cover 503 fits tightly against the outer wall of the device, forming a closed-loop protection, which can effectively prevent dust carried by the air flowing inside the cabinet from adhering and accumulating at the nozzle position, continuously ensuring that the nozzle orifice is clean and unobstructed, forming a continuous isolation protection for the fire extinguishing nozzle, and further improving the structural stability and durability of each component for long-term static use. When a fire is triggered by an abnormality in the electrical components inside cabinet 1, the controller 12 mounted on cabinet 1 acts as a control module, receiving fire response signals in real time. The control module and the drive unit 605 (preferably an electric telescopic rod) are connected by a stable electrical line. The control module continuously transmits action control commands to the drive unit 605 through the electrical connection line. After receiving the electrical signal, the drive unit 605 performs a telescopic operation, driving the rack 602 to slide smoothly along the guide rod 604. The rack 602 meshes with the gear 601, driving the rotating shaft 501 to rotate in a specific direction. Screws are provided at both ends of the rotating shaft 501. The rotary groove 505 rotates synchronously and forms a rolling engagement with the drive shaft 211, synchronously pushing the two limit rods 210 to slide towards each other along the guide rail 212, releasing the locking relationship between the limit rods 210 and the counterweight frame 201. After the counterweight frame 201 loses its limit, under the combined action of the tension spring 205 and its own weight, it slides vertically along the guide frame 204. The roller 206 rolls and changes direction along the trajectory of the inclined groove 209, synchronously pushing the sealing plate 202 to move laterally. The setting of the inclined groove 209 makes the sealing gasket 203 gradually approach the cabinet 1, effectively reducing the initial friction force. Finally, the sealing gasket 203 tightly adheres to the heat dissipation holes of the cabinet 1, achieving a tight seal. This effectively prevents the high-temperature toxic fumes generated by the fire from escaping outwards, reducing the entry of external oxygen into the cabinet and intensifying combustion. It also isolates external oxygen and concentrates the vaporized extinguishing agent, further improving the overall fire extinguishing efficiency inside the cabinet. Simultaneously, the rotating shaft 501 drives the connecting rod 502 and the protective cover 503 to rotate and swing synchronously, moving the protective cover 503 away from the nozzle of the extinguishing device, releasing the obstruction and limiting of the nozzle, and ensuring that the perfluorohexanone extinguishing device 7 can smoothly spray the extinguishing agent. (Note: The last sentence about non-pressurized perfluorohexanone is unrelated and appears to be a separate, incomplete thought.) The ketone fire extinguishing device 7 stores perfluorohexanone extinguishing agent in a liquid state at atmospheric pressure under normal conditions. After receiving the electric start signal from the controller 12, the built-in electric initiator (preferably powered by 24V DC) ignites the driving agent to generate high-pressure gas that pushes the piston. When the pressure reaches 1.2MPa, the rupture disc breaks, and the extinguishing agent is sprayed out through the atomizing nozzle. Utilizing its low boiling point of 49.2℃, it rapidly vaporizes and absorbs a large amount of heat to achieve physical cooling. At the same time, it inhibits the combustion chain reaction by diluting the oxygen concentration and generating free radicals through the decomposition of fluorocarbon bonds at high temperature. The triple mechanism works together to quickly extinguish the electrical fire inside the cabinet 1.
