Abstract
Description
Technical Field
[0001] This utility model relates to the field of real-time monitoring technology for integrated power distribution cabinets, specifically to an integrated power distribution cabinet that can be monitored in real time. Background Technology
[0002] A comprehensive distribution cabinet is a power distribution device that integrates multiple electrical equipment and functions. It centralizes the electrical components that are scattered in traditional power distribution systems, such as circuit breakers, contactors, relays, fuses, current transformers, voltage transformers, and capacitors, into a single cabinet. Through reasonable layout and connection, it achieves comprehensive management of power distribution, control, protection, and other related functions. To ensure the safety of using the comprehensive distribution cabinet, it is necessary to monitor internal temperature and other factors in real time.
[0003] The existing integrated power distribution cabinets that can be monitored in real time use temperature sensors to monitor the internal temperature of the cabinet. When the internal temperature is too high, the exhaust fan at the top of the cabinet starts to run to cool the inside.
[0004] Existing integrated power distribution cabinets with real-time monitoring have temperature sensors set in fixed positions. The data obtained from these fixed temperature sensors cannot fully and accurately reflect the overall temperature distribution inside the cabinet. A single fan at the top is insufficient to effectively and promptly dissipate the heat generated inside the cabinet, which can easily lead to excessively high temperatures in other parts of the cabinet. Therefore, we propose an integrated power distribution cabinet with real-time monitoring. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a comprehensive power distribution cabinet that can be monitored in real time. It can accurately monitor the temperature of a certain location inside the power distribution cabinet in real time. At the same time, multiple fans can generate a larger air volume, which promotes faster air circulation inside the power distribution cabinet and can direct the airflow to different areas inside the power distribution cabinet. This helps to solve the problem of local overheating that may occur inside the power distribution cabinet and can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive power distribution cabinet that can be monitored in real time, including a cabinet body, a mounting frame provided between the left and right inner walls of the cabinet body, and a monitoring mechanism and a heat dissipation mechanism;

Screw rod is rotatably connected between the upper and lower inner walls of the left guide groove. The left end of the support plate is connected to the external thread of the screw rod.
[0008] Heat dissipation mechanism: It includes rotating columns and fans. The upper surface of the support plate is rotatably connected to the rotating columns, and the top of each rotating column is equipped with a fan. It can monitor the temperature of a certain position inside the power distribution cabinet in real time and accurately. At the same time, multiple fans can generate a larger air volume, which promotes faster air circulation inside the power distribution cabinet and can guide the airflow to different areas inside the power distribution cabinet, which helps to solve the problem of local overheating that may occur inside the power distribution cabinet.
[0009] Furthermore, a microcontroller is installed on the left side of the cabinet. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the fans are all electrically connected to the output terminals of the microcontroller.

[0011] Furthermore, the heat dissipation mechanism also includes a rectangular frame, a rack plate, a connecting block, a sliding groove, and gears.

[0013] Furthermore, the front side of the cabinet has evenly distributed air outlets, and the rear side of the cabinet has evenly distributed air inlets, to achieve ventilation inside the power distribution cabinet.
[0014] Furthermore, the front side of the cabinet is hinged with a door, and a handle is provided on the right side of the door for convenient use of the power distribution cabinet.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This integrated power distribution cabinet with real-time monitoring capability has the following advantages:
[0016] 1. By driving the lead screw to rotate through a right-angle motor, the support plate moves the temperature sensor and vision sensor inside the cabinet, enabling real-time monitoring of the cabinet. This allows for accurate and comprehensive monitoring of temperature changes inside the cabinet, ensuring the stable operation of the distribution cabinet.
[0017] 2. The motor drives the rotating shaft to rotate the rotating rod, causing the sliding column to slide inside the sliding groove. The connecting block drives the rack plate to slide inside the clearance hole, causing the meshing gear to drive the fan to swing through the rotating column. This allows the fan to swing left and right inside the cabinet, effectively cooling the inside of the distribution cabinet and preventing uneven heat dissipation that could lead to excessively high temperatures in some areas. The fan angle and height can be adjusted to the most suitable position for heat dissipation in that area, ensuring that each component receives a good heat dissipation environment.

The left end of the support plate 42 is threadedly connected to the external thread of the lead screw 45. Monitoring mechanism 4 includes a right-angle motor 46. A straight-angle motor 46 is provided on the upper surface of the cabinet 1. Angle motor 46 and right-angle motor 46 are fixedly connected at the bottom of the output shaft to the top of lead screw 45. The input end of right-angle motor 46 is electrically connected to the output end of microcontroller 3. Through the control of microcontroller 3, right-angle motor 46 starts to run, and the output shaft will drive lead screw 45 to start to rotate, so that threaded support plate 42 slides up and down inside guide groove 41. Temperature sensor 43 monitors internal temperature in real time and vision sensor 44 transmits real-time image to microcontroller 3. Temperature sensor 43 transmits monitored internal data to microcontroller 3. Microcontroller 3 integrates the monitored data.
[0025] Heat dissipation mechanism 6 includes rotating columns 601 and fans 602. The rotating columns 601 are rotatably connected to the upper surface of the support plate 42. Fans 602 are installed at the top of each rotating column 601. Heat dissipation mechanism 6 also includes a rectangular frame 603, rack plates 604, connecting blocks 605, sliding grooves 606, and gears 610. A rectangular frame 603 is located at the bottom of the support plate 42. Clearance holes are provided on the left and right sides of the rectangular frame 603. Rack plates 604 are slidably connected inside both clearance holes. Connecting blocks 605 are fixedly connected between the two rack plates 604. A groove 606 is provided in the middle of the frame. Gears 610 are fixedly connected to one end of the rotating column 601 extending to the lower surface of the support plate 42. The gears 610 are meshed with the rack plate 604 on the same side. The heat dissipation mechanism 6 also includes a rotating shaft 607, a rotating rod 608, a sliding column 609, and a motor 611. The bottom wall of the rectangular frame 603 is rotatably connected to the rotating shaft 607. The top of the rotating shaft 607 is fixedly connected to the rotating rod 608. The upper surface of the front end of the rotating rod 608 is fixedly connected to the sliding column 609. The sliding column 609 is slidably connected inside the groove 606. The motor 611 is located in the rectangular frame 603. On the lower surface of the frame 603, the top end of the output shaft of motor 611 is fixedly connected to the bottom end of rotating shaft 607. The input end of motor 611 is electrically connected to the output end of microcontroller 3. The input ends of fan 602 are also electrically connected to the output ends of microcontroller 3. Temperature sensor 43 and vision sensor 44 are both bidirectionally electrically connected to microcontroller 3. When the monitored data exceeds the specified value, the fan 602 and motor 611 start to operate through the control of microcontroller 3. Fan 602 will drive the internal fan blades to rotate at high speed, and the output shaft of motor 611 will drive rotating shaft 607 to start rotating. The rotating rod 608 drives the sliding column 609 to start rotating, which in turn causes the sliding column 609 to slide inside the sliding groove 606 inside the connecting block 605. This causes the connecting block 605 to drive the rack plate 604 to slide left and right inside the clearance holes on the left and right sides of the rectangular frame 603, causing the meshing gear 610 to start rotating. The gear 610 drives the fan 602 to swing left and right through the rotating rod 601 and blow air. External air is drawn in through the air inlet on the rear side of the cabinet 1 and the heat inside the cabinet 1 is discharged through the air outlet on the front side, thereby dissipating the temperature inside the integrated power distribution cabinet.
[0026] The working principle of the integrated power distribution cabinet with real-time monitoring provided by this utility model is as follows: When using the power distribution cabinet, first open the hinged cabinet door 5, and fix some equipment such as circuit breakers and contactors to the mounting bracket 2 inside the cabinet 1 with bolts. Through the control of the microcontroller 3, the right-angle motor 46 starts to run, and the output shaft drives the lead screw 45 to start rotating, so that the threaded support plate 42 slides up and down inside the guide groove 41. The temperature sensor 43 monitors the internal temperature in real time, and the vision sensor 44 transmits the real-time image to the microcontroller 3. The temperature sensor 43 transmits the monitored internal data to the microcontroller 3. The microcontroller 3 integrates the monitored data. When the monitored data is greater than the specified value, the microcontroller 3 controls the air supply. When the fan 602 and motor 611 start operating, the fan 602 will drive the internal fan blades to rotate at high speed. The output shaft of the motor 611 will drive the rotating shaft 607 to start rotating. Through the rotating rod 608, the sliding column 609 will start rotating, and then the sliding column 609 will start sliding inside the sliding groove 606 inside the connecting block 605. This will cause the connecting block 605 to drive the rack plate 604 to slide left and right inside the clearance holes on the left and right sides of the rectangular frame 603, causing the meshing gear 610 to start rotating. The gear 610 will drive the fan 602 to swing left and right and blow air through the rotating column 601. External air will be drawn in through the air inlet on the rear side of the cabinet 1, and the heat inside the cabinet 1 will be discharged through the air outlet on the front side, thereby dissipating the temperature inside the integrated power distribution cabinet.
