Abstract
Description
Technical Field

[0002] Plug-in intelligent DC metering devices can perform high-precision measurement of DC power, accurately acquiring parameters such as voltage, current, power, and energy. This provides accurate data for power system billing, energy consumption statistics, and cost accounting, helping users clearly understand their power usage. Its pluggable design allows for easy replacement or upgrading of components such as intelligent modules and transmission modules according to different application scenarios and functional requirements. For example, when it is necessary to improve data transmission capabilities, a higher-speed transmission module can be directly plugged in and replaced without large-scale modifications to the entire device, thus improving the adaptability and scalability of the equipment.
[0003] In the prior art, some pluggable intelligent DC metering devices use heat dissipation holes on the side plate surface for heat dissipation. However, due to the limited internal space layout and natural air convection characteristics, the side heat dissipation holes may not be able to efficiently dissipate the large amount of heat generated by the device operation, and the heat dissipation effect is often unsatisfactory. If the heat dissipation holes are set on the top of the device, although the heat dissipation efficiency can be improved to a certain extent, the top opening is very easy to become a channel for dust to enter the device during daily use, which may pose a potential threat to the internal precision electronic components.

[0036] It should be further noted that the top plate 211 is integrally formed with the side plate 111 to constitute a protective barrier at the top of the device to prevent dust from falling directly into the interior of the device from above, and a circular heat dissipation port is formed on the surface of the top plate 211, the fixed plate 212 is fixed at the heat dissipation port of the top plate 211 to provide a mounting basis for each component in the dustproof assembly 210, the limiting plate 213 is used to limit the movement range of the inner tooth disc 227 to ensure its rotation within the specified track, the rotating column 214 is used to provide rotation support for the tooth plate 215, and the tooth plate 215 can tightly cover the heat dissipation port to block dust from entering when the device is not dissipating heat, thereby playing a dustproof role.
[0037] Preferably, the top plate 211 is located on the side of the side plate 111 away from the back plate 121, and the 0V copper bar 124 is arranged in a circumferential array on the outer surface of the fixed plate 212.
[0038] It should be noted that the conduction assembly 220 includes a heat conduction sleeve 221 fixedly connected to the outer surface of the top plate 211, a thermal expansion block 222 and a sliding block 223 arranged inside the heat conduction sleeve 221, a transmission rod 224 fixedly connected to the side of the sliding block 223 away from the thermal expansion block 222, a protrusion 225 fixedly connected to the outer end surface of the transmission rod 224, a swing block 226 sleeved on the outer surface of the protrusion 225, an inner tooth disc 227 fixedly connected to the outer end surface of the swing block 226 and matched with the toothed plate 215, and a spring 228 sleeved on the outer side of the transmission rod 224.
[0039] It should be noted that the heat conduction sleeve 221 is used to transfer the heat generated during the operation of the device to the thermal expansion block 222, which has the characteristics of expanding when heated and shrinking when cooled. When the internal temperature of the device rises, the thermal expansion block 222 expands and pushes the sliding block 223 to slide along the heat conduction sleeve 221. The transmission rod 224 and the protrusion 225 are driven to move synchronously by the sliding block 223, the swing block 226 is driven to swing by the protrusion 225, and the inner tooth disc 227 is driven to rotate by the swing block 226.

[0040] Further, the outer surface of the sliding block 223 is in sliding contact with the inner wall of the heat conduction sleeve 221, and the outer surface of the inner tooth disc 227 is in sliding contact with the inner surface of the limiting plate 213.

[0042] In use, a DC 48V input terminal 112 is used to introduce a direct current power supply to power the device, and a pluggable intelligent module 113 is used to start precise measurement of direct current parameters such as voltage and current. The measurement data is transmitted to the main control board and the display screen 116, and the data is analyzed, processed and stored while the metering information and module parameters are presented to the user through the display screen. If the device needs to transmit data remotely, the data is uploaded to the management platform through the pluggable 4G transmission module 115; if the module is not full, the false panel device 114 fills the gap, prevents dust and protects the internal circuit.
[0043] When heat is generated during the operation of the device: the heat is transferred to the heat-conducting sleeve 221, the heat is conducted to the internal thermal expansion block 222 through the heat-conducting sleeve 221, the thermal expansion block 222 expands when heated, and pushes the sliding block 223 to slide along the inner wall of the heat-conducting sleeve 221, and then the sliding block 223 drives the transmission rod 224 and the protrusion 225 on the transmission rod 224 to move synchronously, the protrusion 225 drives the swing block 226 to swing, and then the swing block 226 drives the inner tooth disc 227 to rotate, so that the inner tooth disc 227 drives the tooth plate 215 to rotate around the rotating column 214, opens the heat dissipation opening at the top of the device, and dissipates heat;
[0044] When the temperature inside the device decreases: the thermal expansion block 222 shrinks, and the sliding block 223 is reset by the reaction force of the spring 228, so that the tooth plate 215 is re-closed, blocks dust from entering the interior of the device, and ensures stable operation of the device.
[0045] In summary, through the cooperation of the metering device body 100 and the heat dissipation mechanism 200, data processing and display can be more convenient and efficient, and when the device is operating normally, the tooth plate 215 tightly covers the heat dissipation opening, blocks dust from entering, protects the internal precision electronic components, and when the temperature inside the device increases, automatically drives the tooth plate 215 to open the heat dissipation opening, so as to ensure that the device can maintain stable operation in various environments.
