Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box monitoring device. Background Technology

[0002] As the core hub for power distribution and control at the end of the power system, distribution boxes are widely used in urban power grids, industrial production, and civil buildings. Their stable operation directly maintains the safety and continuity of power supply. However, because distribution boxes are mostly deployed in outdoor open environments or areas with high-frequency human activity, they not only face the risk of tilting and overturning due to external impacts such as vehicle collisions and foundation settlement, but also frequently experience situations where operators neglect to close the box doors completely during routine maintenance. Once the box door is open or ajar, foreign objects and small animals can easily enter the box, leading to serious power failures such as leakage and short circuits, posing a significant threat to the safe and stable operation of the power grid and the safety of people's lives and property.

[0003] Currently, there are significant shortcomings in the monitoring technology of distribution boxes, especially in terms of door status control. Traditional solutions mostly rely on sensors to passively sense the opening and closing status of the door and alert to abnormalities through alarm signals. However, such technologies lack proactive closed-loop processing capabilities. When maintenance personnel are unable to handle the situation in a timely manner due to factors such as response delays or distance, the hidden danger of the door being open for a long time still exists, making it difficult to fundamentally prevent power accidents caused by foreign object intrusion. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-5As shown, a power distribution box monitoring device is provided, including a power distribution box 1. The power distribution box 1 includes a box body 2, a box top cover 3, and a box door 4. A mounting groove 7 is symmetrically opened on one side wall of the box body 2. A rotating shaft 6 is rotatably installed in the mounting groove 7, and the two rotating shafts 6 are connected. A fixing block 5 is fitted inside the mounting groove 7 on the outer wall of the rotating shaft 6, and the fixing block 5 is fixedly connected to the box door 4. A drive mechanism for driving the rotating shaft 6 to rotate is provided inside the box top cover 3. A tilt sensor 8 is embedded in one side wall of the box body 2, and a pressure sensor 10 is embedded in the front side of the box body 2 away from the mounting groove 7. A main control wireless module 9 is provided inside the power distribution box 1, which is electrically connected to the tilt sensor 8 and the pressure sensor 10. Through the above structural design, the tilting state of the power distribution box 1 and the closed state of the box door 4 can be monitored, facilitating subsequent targeted processing and improving the operational safety and stability of the power distribution box 1.

[0024] The drive mechanism includes a hollow shaft 12, and a chamber 11 is opened on one side inside the housing 2. The hollow shaft 12 is rotatably mounted on the top side inside the chamber 11. This provides a basic installation structure for the subsequent transmission and power output of the drive mechanism, ensuring the stability of the installation and operation of each component.

[0025] In this example, the driving mechanism also includes an electromagnet 13, which is fixedly installed at the lower end of the hollow shaft 12. A transmission sleeve 14 is slidably fitted onto the outer side of the upper end of the upper rotating shaft 6 within the chamber 11. Slider blocks 15 are symmetrically arranged on the inner wall of the transmission sleeve 14. Sliding grooves 17, adapted to the sliders 15, are symmetrically opened on the outer wall of the upper end of the rotating shaft 6. A receiving groove is opened at the top of the rotating shaft 6, and a spring 16 is installed inside the receiving groove. The two ends of the spring 16 are fixedly connected to the transmission sleeve 14 and the inner wall of the receiving groove, respectively. A gear 20 is fitted onto the outer wall of the hollow shaft 12. One side of the gear 20... A gear 19 is meshed with the gear, and a drive motor 18 is connected below the gear 19. The drive motor 18 is fixedly installed in the chamber 11. A battery 25 for powering the drive motor 18 and the electromagnet 13 is provided on one side of the housing 2. A power supply component for powering the electromagnet 13 is provided in the hollow shaft 12. Through the cooperation of the electromagnet 13, the transmission sleeve 14, the drive motor 18 and the gear 19, the housing door 4 can be automatically closed when needed, realizing active closed-loop processing and eliminating the hidden dangers of the housing door 4 being open for a long time.

[0026] In this example, the transmission sleeve 14 is made of metal that attracts the electromagnet 13. The rotating shaft 6 and the fixing block 5 are fixedly connected. The outer wall of the hollow shaft 12 is rotatably fitted with a support frame, and the two ends of the support frame are fixedly connected to the inner wall of the chamber 11 respectively. By clarifying the material of the transmission sleeve 14 and the connection relationship of each component, it is ensured that the electromagnet 13 and the transmission sleeve 14 can be effectively attracted, thereby ensuring the reliability of the power transmission.

[0027] In this example, the diameter of gear 19 is larger than that of gear 20, and the upper end of hollow shaft 12 is rotatably connected to housing 2 via bearing; the difference in diameter between gear 19 and gear 20 achieves speed reduction and torque increase, improving the power to drive the door 4 to close, and the bearing connection ensures smooth rotation of hollow shaft 12.

[0028] In this example, the power supply component includes a hollow rod 21, which is located inside the hollow shaft 12. The upper end of the hollow rod 21 is fixedly connected to the inner wall of the chamber 11. A power supply line 22 is provided inside the hollow rod 21, and one end of the power supply line 22 is connected to the battery 25. A conductive sheet 23 and a conductive sheet 24 are respectively provided at the lower end of the hollow rod 21 and the top of the electromagnet 13. The conductive sheet 23 is connected to the power supply line 22, and the conductive sheet 23 and the conductive sheet 24 are in contact with each other. The power supply component is cleverly designed to ensure the rotation of the hollow shaft 12 while providing a stable power supply to the electromagnet 13, thus ensuring the normal operation of the drive mechanism.

[0029] In this example, the main control wireless module 9 includes an audible and visual alarm and a wireless communication unit. A fixing slot 26 is provided on one side of the power distribution box 1, and the tilt sensor 8 is fixedly installed inside the tilt sensor 8. The main control wireless module 9 is electrically connected to the power supply battery 25, the drive motor 18, and the electromagnet 13. The audible and visual alarm and wireless communication facilitate timely reminders and remote monitoring, clarify the electrical connection relationship of each component, and ensure that the monitoring and control functions are implemented normally.

[0030] During use, in the status monitoring stage: the tilt sensor 8 collects the tilt angle data of the distribution box 1 in real time, and the pressure sensor 10 continuously monitors the closing pressure signal of the box door 4: whether the box door 4 is closed is determined by the presence or absence of pressure, and the data is transmitted to the main control wireless module 9 in real time. This stage realizes the real-time perception of the tilting status of the distribution box 1 and the closing status of the box door 4, providing a data basis for subsequent processing.

[0031] Software logic judgment phase: The software logic within the main control wireless module 9 executes the following steps in a loop:

[0032] The main control wireless module 9 reads the tilt angle data transmitted by the tilt angle sensor 8. If the tilt angle is detected to be more than 60°, a 5-minute countdown is started. During the countdown, if the tilt angle data shows that the angle of the distribution box 1 has returned to the normal range (less than 60°), the countdown is immediately reset.

[0033] The main control wireless module 9 simultaneously detects the pressure signal of the pressure sensor 10. If the pressure signal disappears, it indicates that the door 4 is not closed. At this time, a 20-minute countdown is started. If the pressure signal recovers during the countdown, that is, the door 4 is closed again, the countdown is reset.

[0034] If either of the above two timers exceeds the limit and fails to reset after the countdown ends, the audible and visual alarm in the main control wireless module 9 will be triggered immediately to trigger a local audible and visual alarm. At the same time, the alarm message will be sent to the cloud platform through the wireless communication unit to notify the operation and maintenance personnel. In addition, the software logic judgment is a conventional technical means in the existing technology.

[0035] Active intervention phase: When the main control wireless module 9 determines that the pressure signal of the pressure sensor 10 has disappeared and the 20-minute countdown has exceeded the limit, it will send a command to the battery 25 to supply power to the drive motor 18 and the electromagnet 13. After the electromagnet 13 is energized, it generates magnetism, attracts the metal transmission sleeve 14, and causes the transmission sleeve 14 to stretch the spring 16. At the same time, the drive motor 18 starts and drives the hollow shaft 12 to rotate through the meshing of gear 19 and gear 20. Then, through the transmission sleeve 14, it drives the slider 15, which in turn drives the rotating shaft 6 to rotate in conjunction with the slide groove 17. The rotating shaft 6 drives the fixed block 5, and finally drives the box door 4 to flip and close, realizing the active closed-loop processing of the box door 4 in the open state. During this process, the power supply component inside the hollow shaft 12 ensures that the electromagnet 13 can continuously and stably obtain power supply when the hollow shaft 12 rotates through the contact of conductive sheet 1 23 and conductive sheet 2 24.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
