Description

Technical Field

[0001] This invention relates to the field of power supply equipment technology, specifically to an intelligent power distribution and supply equipment with overload arc protection. Background Technology

[0002] In the field of intelligent power distribution and supply equipment, existing power supply equipment typically adopts a standardized cabinet structure, which integrates a variety of electrical components, such as circuit breakers, contactors, and relays, to realize the distribution, control, and protection of electrical energy. Existing technologies have significant shortcomings in arc flash protection. When power distribution equipment experiences overload or insulation failure, arc flash can easily occur. Traditional detection methods, such as thermal elements or smoke detectors, often have delayed responses, failing to achieve rapid and accurate fault location. Fire extinguishing systems often rely on integrated sprinkler systems or external fire-fighting facilities, lacking integrated local suppression mechanisms. This results in low fire extinguishing efficiency when arc flash ignites a fire, potentially affecting the entire system's operation. Furthermore, fixed equipment zones make dynamic isolation difficult, allowing dangerous areas to easily spread during faults, increasing the risk of safety accidents. In terms of maintenance, disassembly and replacement of components typically require cumbersome manual operations, lacking intelligent auxiliary functions, further reducing equipment reliability and user experience. Therefore, we propose an intelligent power distribution device with overload arc flash protection. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an intelligent power distribution and supply equipment with overload arc protection. It can achieve flexible partition isolation through sliding partitions, integrate arc and smoke sensors for multiple early fault detection, and use automated movement and spraying components to achieve rapid and accurate local arc suppression, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent power distribution and supply equipment with overload arc protection, comprising a cabinet and a partition assembly; Cabinet: A movable component is installed on the left side, a feeding component is installed on the left side of the movable component, an injection component is installed on the right side of the movable component, and an injection component is installed on the left side of the feeding component. The partition assembly includes guide grooves, partition plates, arc light sensors, smoke sensors, and wiring holes. Two corresponding guide grooves are provided on the left and right sides of the cabinet interior. A partition plate is installed inside the cabinet, slidably connected to the two corresponding guide grooves. An arc light sensor and a smoke sensor are installed at the front upper side of the partition plate. Evenly distributed wiring holes are provided on the rear side of the partition plate. A spraying assembly is installed inside the partition plate. A fixing assembly is installed at the rear of the partition assembly. The slidable partition plate achieves flexible partitioning and isolation of the electrical units within the cabinet. An appropriate number of partition plates can be added as needed, facilitating wiring and maintenance, and localizing hazardous areas in the event of a fault. The arc light sensor and smoke sensor integrated at the front of the partition plate form a multi-layered, early fault detection network, providing crucial early warning time for the system. The fixing assembly ensures the stability of the partition plate in its working position. This design highly integrates detection, isolation, and initial suppression functions, achieving a leap from passive protection to active safety. Both the arc light sensor and the smoke sensor are bidirectionally electrically connected to an external PLC controller.

[0005] Furthermore, the spraying assembly includes a guide channel and nozzles. The guide channel is provided inside the partition plate, and the lower side of the partition plate has evenly distributed openings, all of which communicate with the guide channel. Nozzles are installed inside the openings. The guide channel serves as a distribution channel for the extinguishing agent, which can quickly guide the extinguishing agent to each nozzle. The evenly distributed nozzles ensure that the extinguishing agent can cover a wider area below the partition plate, achieving a highly efficient and uniform fire extinguishing effect and effectively suppressing fires caused by electric arcs.

[0006] Furthermore, the movable component includes a fixed frame, a movable frame, a threaded rod, a limiting rod, and a motor. A strip-shaped opening is provided on the left side of the cabinet, inside which the fixed frame is fixed. The movable frame is slidably connected inside the fixed frame. A threaded hole is provided on the rear side of the movable frame, inside which a threaded rod is threadedly connected. The threaded rod is rotatably connected inside the fixed frame. A motor is mounted on the upper side of the fixed frame, and the motor's output shaft is fixed to the upper end of the threaded rod. A limiting hole is provided on the front side of the movable frame, inside which a limiting rod is slidably connected. The limiting rod is fixed inside the fixed frame. The input end of the motor is electrically connected to the output end of an external PLC controller. The motor drives the threaded rod to rotate, causing the movable frame to move precisely vertically, thereby adjusting the height of the injection component to correspond to the injection holes on the sides of different partition plates.

[0007] Furthermore, the injection assembly includes a slide tube, a connecting plate, an electric telescopic rod, and an injection hole. A sliding opening is provided on the side of the movable frame, and a slide tube is slidably connected inside the sliding opening.

An electric telescopic rod is installed on the left side of the movable frame, and the telescopic arm of the electric telescopic rod is fixed to the side of the connecting plate. An injection hole is provided on the left side of the partition plate, and the injection hole communicates with the guide channel. The right end of the slide tube is engaged inside the injection hole. The input end of the electric telescopic rod is electrically connected to the output end of an external PLC controller. The electric telescopic rod can push the slide tube to move precisely, causing its right end to automatically align with or detach from the injection hole on the partition plate.

[0008] Furthermore, the feeding assembly includes a connecting strip, a connecting hose, a feeding pipe, and a solenoid valve. The connecting strip is fixed to the left side of the movable frame, and a strip-shaped opening is provided on the left side of the fixed frame. The connecting strip is slidably connected inside the strip-shaped opening. A connecting hose is fixed to the left end inside the sliding pipe, and a feeding pipe is fixed to the left end of the surface of the connecting hose. A solenoid valve is installed on the circumference of the feeding pipe. The input end of the solenoid valve is electrically connected to the output end of an external PLC controller. The connecting hose can adapt to the lifting and lowering movement of the movable frame. The solenoid valve is controlled by an external PLC and acts as a switch for the extinguishing agent. It opens immediately after receiving an alarm signal to ensure timely supply of extinguishing agent.

[0009] Furthermore, the injection assembly includes a connecting block, a storage tank, and an L-shaped guide hole. The connecting block is fixed to the left side of the connecting strip, and an L-shaped guide hole is formed inside the connecting block. The left end of the feed pipe is fixed to the right end inside the L-shaped guide hole. The lower end of the storage tank is threadedly connected to the upper end inside the L-shaped guide hole. The storage tank is fixed to the connecting block by a threaded connection, which facilitates quick disassembly and replacement. The L-shaped guide hole forms a sealed flow channel from the storage tank to the feed pipe. The structure is compact and highly integrated.

[0010] Furthermore, it also includes a sensing component, which comprises a reflector and an infrared sensor. A groove is provided on the right side of the moving frame, and the infrared sensor is installed inside the groove. A reflector is fixed on the left side of the partition plate. The infrared sensor corresponds to the reflector and is bidirectionally electrically connected to an external PLC controller. During the movement of the moving frame, if the infrared sensor receives a signal returned by the reflector after the moving frame is adjusted, it indicates that the docking is successful. The external PLC controller can then determine that the system is ready, thus improving the reliability and safety of automated operation.

[0011] Furthermore, the fixing assembly includes a fixing post, a connecting post, a toggle cover, a torsion spring, a connecting hole, a limiting hole, and a limiting block. The rear side of the cabinet has evenly distributed connecting holes. Two corresponding limiting holes are provided at the left and right ends of each connecting hole.

The fixing post and the toggle cover are located inside the corresponding connecting holes. Two corresponding limiting blocks are fixed to the upper and lower ends of the surface of the toggle cover. The two limiting blocks are in contact with the rear side of the cabinet. By rotating the toggle cover, the energy stored in the torsion spring and the engagement of the limiting blocks with the limiting holes are used to achieve a secure fixation or convenient unlocking of the partition plate on the cabinet, facilitating maintenance and adjustment of the equipment's interior.

[0012] Furthermore, an annular groove is formed on the circumferential surface of the toggle cover, and a toggle ring is fixed inside the annular groove. The toggle ring has evenly distributed anti-slip grooves on its circumferential surface. The design of the toggle ring increases the friction and comfort when the hand is operating it, and the anti-slip grooves make the operation of rotating the toggle cover more effortless and accurate.

[0013] Furthermore, a baffle is hinged to the front of the cabinet, and an observation port is provided on the right side of the baffle. A transparent panel is fixed inside the observation port, and a lock is installed on the right side of the baffle.

During the movement of the moving frame 42, if the infrared sensor 82 receives a signal returned by the reflector 81 after the moving frame 42 adjusts its position, it indicates successful docking.An external PLC controller can determine system readiness, improving the reliability and safety of automated operation. Storage tank 72 is fixed to connecting block 71 via a threaded connection, facilitating quick disassembly and replacement. L-shaped guide holes 73 form a sealed flow channel from storage tank to feed pipe 63, resulting in a compact structure and high integration. Connecting hose 62 can accommodate the lifting and lowering movement of moving frame 42. Solenoid valve 64, controlled by an external PLC, acts as a switch for the extinguishing agent, opening immediately upon receiving an alarm signal to ensure timely supply of extinguishing agent. Electric telescopic rod 53 can precisely move slide tube 51, automatically aligning or disengaging its right end with the injection hole 54 on the partition plate. Motor 45 drives threaded rod 43 to rotate, causing moving frame 42 to move precisely vertically, thereby adjusting the height of injection assembly 5 to correspond with injection holes 54 on different sides of partition plate 22. Separation component 2 includes guide grooves 21, partition plates 22, arc light sensors 23, smoke sensors 24, and wiring holes 25. Two corresponding guide grooves 21 are provided on the left and right sides inside the cabinet 1. A partition plate 22 is provided inside the cabinet 1, and the partition plate 22 is slidably connected to the corresponding two guide grooves 21. An arc light sensor 23 and a smoke sensor 24 are installed on the front upper side of the partition plate 22.

The fixing assembly 9 includes a fixing post 91, a connecting post 92, a deflector cover 93, a torsion spring 94, a connecting hole 95, a limiting hole 96, and a limiting block 97. The cabinet 1 has evenly distributed connecting holes 95 on its rear side. Two corresponding limiting holes 96 are provided at the left and right ends of each connecting hole 95. A connecting post 92 is fixed to the rear side of the partition 22. The deflector cover 93 is rotatably connected to the rear end of the connecting post 92. A torsion spring 94 is fitted onto the circumferential surface of the connecting post 92. The rear end of the torsion spring 94 is fixed inside the deflector cover 93. The front end is fixed to the rear end of the fixing column 91. The fixing column 91 and the actuating cover 93 are located inside the corresponding connecting hole 95. Two corresponding limiting blocks 97 are fixed at the upper and lower ends of the surface of the actuating cover 93. The two limiting blocks 97 are in contact with the rear side of the cabinet 1. By rotating the actuating cover 93, the energy stored in the torsion spring 94 and the engagement of the limiting blocks 97 with the limiting hole 96 are used to achieve a firm fixation or easy unlocking of the partition plate 22 on the cabinet 1, which facilitates maintenance and adjustment of the equipment. The guide channel 31 serves as a distribution channel for the extinguishing agent, which can quickly guide the extinguishing agent to each nozzle 32. The evenly distributed nozzles 32 ensure that the extinguishing agent can cover a wider area below the partition plate, achieving high efficiency and uniformity. The uniform fire extinguishing effect effectively suppresses fires caused by electric arcs. The sliding partition 22 enables flexible partitioning and isolation of electrical units within the cabinet. During use, an appropriate number of partitions 22 can be added as needed, which not only facilitates wiring and maintenance but also localizes the dangerous area in the event of a fault. The arc light sensor 23 and smoke sensor 24 integrated at the front end of the partition provide a multi-layered, early fault detection network for electrical components installed on the upper side of the partition 22, providing crucial early warning time for the system. The fixing component 9 ensures the stability of the partition in its working position. This design highly integrates detection, isolation, and initial suppression functions, achieving a leap from passive protection to active safety. Among them, arc light sensor 23 and smoke sensor 24 are both bidirectionally electrically connected to an external PLC controller.

[0019] Among them, an annular groove is provided on the circumferential surface of the toggle cover 93, and a toggle ring 13 is fixed inside the annular groove. The toggle ring 13 has evenly distributed anti-slip grooves on its circumferential surface. The design of the toggle ring 13 increases the friction and comfort when the hand is operating, and the anti-slip grooves make the operation of rotating the toggle cover 93 easier and more accurate.

[0020] Among them: a baffle 10 is hinged to the front side of the cabinet 1, an observation port is opened on the right side of the baffle 10, a transparent plate 11 is fixed inside the observation port, and a lock 12 is installed on the right side of the baffle 10. The baffle 10 and the lock 12 provide basic physical security and access control for the equipment. The transparent plate 11 allows staff to observe the internal status of the equipment directly without opening the baffle 10.

[0021] The working principle of the intelligent power distribution equipment with overload arc protection provided by this invention is as follows: First, select an appropriate number of partition plates 22 according to the actual power distribution needs. Slide them into the guide grooves 21 on the left and right sides inside the cabinet 1 to achieve flexible partitioning. During installation, align the connecting post 92 on the rear side of the partition plate 22 with the connecting hole 95 at the rear of the cabinet 1. Then insert the connecting post 92 and the actuating cover 93. After insertion, the actuating cover 9, under the action of the torsion spring 94, causes the two limit blocks 97 connected to it to move away from the corresponding two limit holes 96. In this way, the partition plate 22 can be firmly fixed, ensuring its stability in the working position. Subsequently, electrical equipment such as circuit breakers and contactors are installed on the upper side of the partition plate 22 and wired through the evenly distributed wiring holes 25 on the rear side of the partition plate 22. Simultaneously, the arc sensor 23 and the smoke sensor 24 are integrated on the upper front end of the partition plate 22 for real-time monitoring of the operating status of the upper electrical units. When the equipment is powered on, if an overload or insulation fault causes an arc, the arc sensor 23 and the smoke sensor 24 will activate. Sensor 24 quickly detects abnormal light or smoke signals and transmits the data to an external PLC controller via a bidirectional electrical connection. The controller then triggers motor 45 of moving component 4, driving threaded rod 43 to rotate, causing moving frame 42 to move vertically along limit rod 44 to the height corresponding to injection hole 54 of target partition plate 22. At this time, reflector 81 of sensing component 8 interacts with infrared sensor 82 on the left side of partition plate 22. After confirming accurate docking, electric telescopic rod 53 of injection component 5 pushes connecting plate 52 to move slide tube 51 to the right. When the end is inserted into the injection hole 54, the solenoid valve 64 of the feeding assembly 6 is opened, and the extinguishing agent flows from the storage tank 72 through the L-shaped guide hole 73, the feeding pipe 63 and the connecting hose 62 into the slide pipe 51, and then enters the guide groove 31 inside the partition plate 22 through the injection hole 54. Finally, it is sprayed downward by the evenly distributed nozzles 32 to achieve localized and efficient fire extinguishing. The fixing assembly 9 always keeps the partition plate 22 stable, and the baffle 10 and the transparent plate 11 facilitate external observation. The whole process realizes closed-loop automated management from partition installation, electrical integration to intelligent protection.

[0022] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The arc light sensor 23, smoke sensor 24, infrared sensor 82, motor 45, electric telescopic rod 53 and solenoid valve 64 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of motor 45, electric telescopic rod 53 and solenoid valve 64 using methods commonly used in the prior art.
