Description
Technical Field
[0001] This invention relates to the field of metering and distribution box technology, and in particular to a safety monitoring device for metering and distribution boxes. Background Technology
[0002] Currently, most traditional metering and distribution boxes and their internal equipment lack safety monitoring agencies. Regular personnel inspections are typically used to ensure their proper functioning. However, this often results in delays in obtaining timely information and proactive intervention when safety risks arise, such as equipment damage, unauthorized opening or prying of the boxes, electricity theft, or fire hazards from high heat and smoke. This not only poses significant safety hazards but also causes incalculable property damage and negatively impacts the electricity supply to residents and factories in the surrounding area.
[0003] Therefore, there is an urgent need for a safety monitoring device for metering and distribution cabinets that can facilitate operators to obtain status information of metering and distribution cabinets in a timely manner, improve safety performance, and reduce property losses. Summary of the Invention
[0004] The purpose of this invention is to provide a safety monitoring device for metering and distribution boxes, which can obtain the status information of metering and distribution boxes in a timely manner, so that inspection personnel can make timely feedback, reduce safety hazards, reduce property losses, and at the same time ensure the normal power supply in the surrounding area.
[0005] The present invention adopts the following technical solution: A safety monitoring device for a metering and distribution box includes a signal transmission module mounted on the cabinet. A distance sensor and a smoke alarm connected to the signal transmission module are installed inside the cabinet. A support frame inside the cabinet has buffer components on all sides except the side opposite the cabinet door. The distance sensor is mounted on the inner wall of the cabinet within the buffer components. An early warning component connected to the signal transmission module is installed on the cabinet door; the early warning component is powered on and operates when the cabinet door is opened.
[0006] Preferably, the support frame is provided with multiple layers of partitions spaced apart along its height direction.
[0007] Preferably, the buffer assembly includes an arc-shaped buffer plate that is elastically connected to the support frame, and in the initial state, one protruding end of the buffer plate is in contact with the inner wall of the cabinet.
[0008] Preferably, the buffer plate has a cross-shaped structure.
[0009] Preferably, a slider is provided at one end of the buffer plate near the support frame, and a groove is provided on the support frame for the slider to slide.
[0010] Preferably, a first buffer spring connected to the slider is provided in the groove.
[0011] Preferably, the early warning component includes an early warning receiving terminal, which is connected to the signal transmission module and is disposed on the inner wall of the cabinet door; the early warning receiving terminal is elastically disposed on the early warning receiving terminal and connected to the circuit; the trigger terminal is connected to a door lock disposed inside the cabinet door via a pull rope, and the end of the partition is provided with a lock groove, which is inserted into the lock groove as the door lock rotates, and the trigger terminal is disconnected from the early warning receiving terminal.
[0012] Preferably, four warning receiving terminals are provided, respectively arranged at the top, bottom, left, and right positions of the cabinet door; a winding wheel is coaxially provided on the door lock, and the pull rope is connected to the winding wheel.
[0013] Preferably, the door lock is located on the center line of the cabinet door, and the early warning receiving terminals are respectively located in the middle of the corresponding positions on the cabinet door.
[0014] Preferably, the buffer plate is elastically connected to the support frame via a second buffer spring.
[0015] Compared with the prior art, the beneficial effects of this invention are as follows: By setting up a distance sensor, this invention can promptly transmit the relevant signals acquired when the cabinet shell is deformed by external impact to the transmission module, which then promptly feeds the information back to the relevant monitoring equipment, providing convenience for timely feedback from operators, effectively improving safety, and reducing property losses. The smoke alarm can promptly transmit information when a fire occurs in the equipment components inside the cabinet, reducing the scope of power outages and equipment losses, and ensuring power supply for the surrounding area.
[0016] The support frame and buffer components protect the equipment components inside the cabinet. When the cabinet is subjected to external impact, the buffer components can absorb some of the force through their structure, reducing damage to the cabinet and further minimizing property loss. The early warning system provides a warning when the cabinet door is opened. This ensures that if electricity theft or other theft occurs, the early warning system can promptly relay relevant information to the monitoring equipment so that staff can quickly locate and handle the situation.

Detailed Implementation
[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, the safety monitoring device for a metering distribution box cabinet of the present invention includes a signal transmission module 1. The signal transmission module 1 is used to receive signals from a distance sensor 2 and a smoke alarm 3, so as to transmit relevant information to the monitoring equipment (the monitoring computer in the monitoring room or the mobile phone of the operator) so that the staff can locate the position in time and make a rapid response. The specific model of the signal transmission module 1 can be adapted according to the dispersion, location and surrounding environment of the cabinet 6. It is preferable to use a low-power (suitable for long-term uninterrupted operation) and wide-coverage NB-IoT wireless transmission module. The cabinet 6 is equipped with a distance sensor 2 and a smoke alarm 3 connected to the signal transmission module 1. The distance sensor 2 needs to meet the requirements of short-distance measurement, fast response speed (≤100ms), anti-electromagnetic interference (adapting to the electrical environment inside the cabinet), and output signal that can be directly connected to the signal transmission module 1 (such as UART, switch signal). The specific model can be the BannerQ45ULIU62VP ultrasonic distance sensor. The smoke alarm 3 needs to meet the requirements of fast smoke response (≤30 seconds) and support signal output (switch signal / Features such as relays (facilitating connection to transmission modules), industrial-grade protection (adapting to high temperatures and dust inside cabinets), and the Siemens FDO210 industrial-grade photoelectric smoke alarm can be selected.
[0019] The support frame 4 inside the cabinet 6 is a rectangular frame structure that matches the internal space of the cabinet 6. Except for the side opposite the cabinet door 7, all other sides of the support frame 4 are equipped with buffer components against the inner wall of the cabinet 6. These buffer components can resist certain external impacts and reduce damage to the cabinet 6. In this embodiment, multiple partitions 5 are spaced along the height of the support frame 4. Various equipment components inside the cabinet 6 can be installed using the partitions 5 as carriers. With the combined action of the support frame 4 and the buffer components, damage to internal components caused by external impacts to the cabinet 6 can be effectively reduced, ensuring both safety and efficiency. The system ensures normal operation while minimizing property damage. Distance sensor 2 is installed on the inner wall of the buffer assembly cabinet 6 to monitor its distance from the supporting frame 4. When the cabinet 6 deforms due to external impact, distance sensor 2 transmits information to signal transmission module 1, which then relays it to staff for timely response. A warning component connected to signal transmission module 1 is installed on the cabinet door 7. When the cabinet door 7 is opened, the warning component is powered on, and signal transmission module 1 transmits this signal to the back-end monitoring equipment, providing timely feedback to staff when the cabinet door 7 is abnormally opened.
[0020] Furthermore, in this embodiment, the buffer assembly includes an arc-shaped buffer plate 8 elastically connected to the support frame 4. The buffer plate 8 is a metal plate with a certain degree of elasticity. In the initial state, one protruding end of the buffer plate 8 contacts the inner wall of the cabinet 6. The middle part of the buffer plate 8 is elastically connected to the support frame 4 through a second buffer spring 9. As the cabinet 6 suffers external impact, the buffer plate 8 deforms under force, and in cooperation with the second buffer spring 9, it offsets part of the external force, reduces the deformation of the cabinet 6, reduces the probability of damage and replacement of the cabinet 6, and reduces property loss. Figure 2 As shown, the buffer plate 8 has a cross-shaped structure, which provides bidirectional buffering for the cabinet 6 both horizontally and vertically, further ensuring the structural stability of the cabinet 6 and enhancing its ability to resist external impacts. This also buys time for staff to arrive on-site for handling.
[0021] Preferably, a slider 10 is provided at one end of the buffer plate 8 near the support frame 4. Four sliders 10 are provided, located at the four corners of the cross-shaped buffer plate 8. The support frame 4 is provided with a groove 11 for the sliders 10 to slide. This arrangement establishes a connection between the buffer plate 8 and the support frame 4, providing orderly guidance for the deformation of the support plate under force. In addition, a first buffer spring 12 connected to the slider 10 is provided in the groove 11. The first buffer spring 12 helps the buffer plate 8 to quickly return to its original position after being subjected to force, and also enhances the ability of the buffer plate 8 to resist external forces.
[0022] Furthermore, the warning component includes a warning receiving terminal 13, which is connected to the signal transmission module 1 and is located on the inner wall of the cabinet door 7. A trigger terminal 15, connected to the circuit, is elastically mounted on the warning receiving terminal 13 via a limiting spring 14. The trigger terminal 15 is connected to a door lock 17 located inside the cabinet door 7 via a pull rope 16. A lock groove 18 is provided at the end of the partition 5. As the door lock 17 rotates into the lock groove 18, the trigger terminal 15 disconnects from the warning receiving terminal 13. When the cabinet door 7 is opened, as the door lock 17 rotates out of the lock groove 18 of the trigger terminal 15, the tension of the pull rope 16 is released, and the trigger terminal 15 contacts the warning receiving terminal 13 under the restoring force of the limiting spring 14, completing the conductive path. The warning receiving terminal 13 then issues an alarm, indicating that the door is open. A manual switch is provided on the warning receiving terminal 13 so that the warning function can be actively deactivated after normal opening. The door lock 17 in this embodiment is the same as the door lock 17 of the electrical cabinet in the prior art. As the key is inserted into the keyhole and turned, the door lock 17 rotates, completing the locking. The difference lies in the lock groove 18, which is a structure that matches the door lock 17. It has an accommodating space on one side. As the cabinet door 7 closes, the door lock 17 naturally enters the lock groove 18. As the door lock 17 rotates, it rotates into the accommodating space, completing the locking. The door lock 17 can only be opened when it rotates counterclockwise to the state corresponding to the lock groove 18.
[0023] Four warning receiving terminals 13 are provided, respectively located at the top, bottom, left, and right positions of the cabinet door 7. A winding wheel 19 is coaxially mounted on the door lock 17. When the door lock 17 is working, the winding wheel 19 rotates synchronously, and the pull rope 16 is connected to the winding wheel 19. The door lock 17 is located on the center line of the cabinet door 7, and the warning receiving terminals 13 are respectively located in the middle of the corresponding positions on the cabinet door 7. This arrangement of the pull rope 16 in both the horizontal and vertical directions can prevent thieves from directly cutting the cabinet door 7 without damaging the door lock 17. Regardless of which direction the pull rope 16 is cut, a conductive path for the warning component can be established to perform the warning operation, further improving the practicality of the invention. To achieve synchronous winding of the pull rope 16 in multiple directions when the door lock 17 rotates, the pull ropes 16 at different positions can be wound with the winding wheel 19 from different directions. Those skilled in the art can adjust this according to the rotation direction. It is only necessary to complete the synchronous outward movement of the four trigger terminals 15 under the rotation of the door lock 17. In addition, in this embodiment, the wires connected to the trigger terminal 15 are partially redundant to facilitate its movement and prevent the wires connected to the circuit from breaking during the movement of the trigger terminal 15.
[0024] When this invention is in operation, if unauthorized personnel improperly open the equipment and impact the side wall of the cabinet 6, the distance sensor 2 will send a signal to the signal transmission module 1. The signal transmission module 1 will then relay the information to the back-end monitoring equipment or the mobile phone of the on-duty personnel, allowing staff to promptly respond to the situation. The early warning component provides warnings for improper opening of the cabinet door 7 or attempts to cut or damage it, and the signal transmission module 1 will relay this information to the back-end monitoring equipment or the mobile phone of the on-duty personnel for timely intervention. The buffer component provides cushioning protection for the cabinet 6, reducing damage caused by external impacts. Through these devices, personal injury and property loss due to safety accidents and power outages caused by equipment malfunctions can be directly or indirectly reduced or avoided, ensuring the normal operation of production and daily life.
