Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, and in particular to a combined smart meter. Background Technology

[0002] Electricity meters are one of the basic devices for power grid data acquisition. They are commonly used for tasks such as collecting, measuring, and transmitting raw electrical energy data, and are the foundation for information integration, analysis, optimization, and presentation. Currently, traditional electricity meters have been largely replaced by smart meters. In addition to the basic electricity metering function of traditional meters, smart meters also have intelligent functions such as bidirectional multi-rate calculation, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features.

[0003] Modular smart meters are a widely used type of meter system. The combined deployment of multiple smart meters allows for centralized management of a large number of meters within the same area. For example, in rental properties or factories, modular meters can manage overall electricity consumption as well as individual meter usage. However, current technology mostly allows for side assembly of meters, not vertical assembly, significantly limiting the total number of meters that can be assembled and preventing vertical expansion. Furthermore, existing meters typically have ventilation openings on both sides of the casing for heat dissipation. However, the overlapping and obstruction on the sides of existing modular meters prevents the effective application of conventional side-cooling methods. Additionally, existing meters are usually mounted against walls for stability, leaving no effective ventilation openings on the back. Moreover, some existing modular smart meters are installed directly outdoors. During heavy rain, rising water levels can easily seep into the casing through the ventilation openings, causing short circuits and other malfunctions in electrical components. Existing ventilation openings cannot automatically seal in low-temperature, heavy rain conditions to protect internal electrical components. Finally, existing electricity meters typically have a filter structure in their air intake channel to filter the cooling airflow. This allows the airflow to cool the inside of the meter while preventing electrical components from being encased in impurities that would affect their heat dissipation. However, the filtering capacity of existing filter structures decreases after a certain period of use and cannot maintain a high-efficiency filtering capacity for a long time. They are easily blocked by impurities, preventing sufficient cooling airflow and affecting the heat dissipation effect. Utility Model Content

The waterproof heat dissipation chamber designed in this application can simultaneously output cooling airflow and use the cooling airflow to clean the circulating filter components, thus improving the continuous filtration capacity of the circulating filter components. This ensures the abundance and cleanliness of the input airflow, preventing the electrical components inside the meter box from being covered in dust and reducing their heat dissipation capacity. It also continuously filters sufficient airflow to adequately dissipate heat from the electrical components, ensuring their stable operation. Furthermore, the waterproof heat dissipation chamber can change the opening and closing state of its airflow channel according to changes in the external water level, effectively preventing the risk of external water entering the meter box through the heat dissipation channel and causing malfunctions, greatly improving the operational stability of the meter box.

[0029] The following is a detailed explanation with reference to the accompanying drawings.

[0030] Example 1

[0031] This application provides a combined smart meter, which includes a base 1, a smart meter body 2, a waterproof heat dissipation chamber 3, an air intake assembly 4, a circulating filter assembly 5, and a removable top cover 6.

[0032] according to Figure 1-6In one specific embodiment, a base 1 pre-cast from reinforced concrete or similar materials is installed in the ground. A smart meter body 2, consisting of several meter boxes 21 arranged side-by-side and / or stacked, is mounted on the base 1. A waterproof heat dissipation chamber 3, capable of transferring heat within the box cavity, is embedded in the bottom of each meter box 21. An air intake assembly 4, which defines the airflow passage, and a circulating filter assembly 5, which continuously filters the input airflow of the air intake assembly 4, are also installed on the front side of the meter box 21. A removable top cover 6, capable of shielding the top of the smart meter body 2, is also detachably installed. The smart meter body 2 provided in this application allows for the assembly and combination of different numbers of meter boxes in different directions as needed, thereby increasing the number of combinations and the overall combination effect. The waterproof heat dissipation chamber 3 of this application can clean the circulating filter assembly 5 while outputting heat dissipation airflow, thereby improving the continuous filtration capacity of the circulating filter assembly 5. This ensures the abundance and cleanliness of the input airflow, preventing the electrical components in the meter box from being covered by dust and reducing their heat dissipation capacity. It also continuously filters sufficient airflow to adequately dissipate heat from the electrical components, ensuring their stable operation. Furthermore, the waterproof heat dissipation chamber 3 can change the opening and closing state of its airflow channel according to changes in the external water level, effectively preventing the risk of external water entering the meter box 21 through the heat dissipation channel and causing malfunctions, greatly improving the operational stability of the meter box 21. The air intake assembly 4 of this application can define the positions of the air inlet and outlet, allowing the drawn heat dissipation airflow to pass through most of the internal space of the meter box 21 to effectively exchange heat with the electrical components. The air intake assembly 4 also features an open notch to facilitate the relocation of the circulating filter assembly 5, allowing the circulating filter assembly 5 to automatically and periodically switch the filter unit 54 to ensure continuous filtration. The circulating filter assembly 5 provided in this application can replace the filter unit 54 by intermittent deflection, so that the filter unit 54 in the flow channel defined by the air intake assembly 4 always maintains a high filtration capacity, thereby improving the continuous filtration effect. The detachable top cover 6 provided in this application can be quickly disassembled and assembled, thereby facilitating the stacking and combination of different numbers of meter boxes 21.

[0033] Preferably, the main body 2 of the smart meter is formed by assembling several meter boxes through a splicing method using inserts and locking with nuts. Each meter box 21 has a window on its front side for easy disassembly and maintenance of internal electrical components, and the edge of the window is connected to a cover 22 that can seal the window. Preferably, first insertion positioning holes 211 and first insertion positioning rods 212 are respectively provided on opposite sides of the meter box 21 for easy side-by-side assembly. More preferably, the top and bottom ends of the meter box 21 are respectively provided with second insertion positioning holes 213 and second insertion positioning rods 214 for easy stacking assembly. Preferably, the cover 22 is connected to the meter box 21 via a rotating shaft installed on the edge of the front window of the meter box 21. More preferably, the side of the cover 22 away from the rotating shaft is provided with a structure such as a locking body to limit the relative position of the cover 22 and the meter box 21, so that the cover 22 can seal the front window of the meter box 21. Preferably, the cover 22 is also provided with a transparent observation window for observing the interior of the meter box 21. Preferably, the surface of the cover 22 is also provided with a strip-arc brush for brushing the filter screen / filter plate. Preferably, the interior of the meter box 21 is provided with at least the necessary built-in accessories such as the inlet switch 23, the smart meter 24 inlet isolation switch 25, and the outlet leakage current switch 26. Specifically, the specific information, configuration relationship, and data of the existing accessories of the inlet switch 23, the smart meter 24 inlet isolation switch 25, and the outlet leakage current switch 26 can be directly referred to the meter box structure in the existing patent with publication number CN212811047U. Preferably, the top of the bottom row of the meter box 21 is also provided with a forward-extending dust collection plate to collect and block impurities carried by the heat dissipation airflow output from the upper meter box 21, so as to avoid excessive impurities in the lower intake air and block the filter screen, thus ensuring the heat dissipation capacity of the lower layer.

[0034] Preferably, the waterproof heat dissipation chamber 3 includes a chamber body 31, an inclined exhaust main pipe 32, a vertical exhaust branch pipe 33, an external exhaust pipe 34, and an undulating sealing mechanism 35. Preferably, the chamber body 31 is embedded in the bottom of the meter box 21. More preferably, the inclined exhaust main pipe 32 is inserted at intervals on the front side of the chamber body 31. Preferably, vertical exhaust branch pipes 33, which can connect the cavity of the inclined exhaust main pipe 32 to the cavity of the meter box 21, are connected at intervals on the pipe body of the inclined exhaust main pipe 32 inside the chamber body 31. Preferably, the inclined exhaust main pipe 32 is also provided with an undulating sealing mechanism 35 that can adjust the sealing of its cavity. Preferably, the output end of the inclined exhaust main pipe 32 is also connected to an external exhaust pipe 34. Preferably, the inclined exhaust main pipe 32 is inclinedly inserted into the chamber body 31, and the inclined exhaust main pipe 32 is preferably a square pipe. The waterproof heat dissipation chamber 3 of this application utilizes multiple parallel channels for exhaust of heat dissipation airflow. Multiple inclined exhaust pipes 32 are arranged with height differences, ensuring the waterproof heat dissipation chamber 3 maintains a certain exhaust capacity under different water levels, guaranteeing effective heat dissipation. When the external water level is high enough and the waterproof heat dissipation chamber 3 is completely sealed, the water directly contacts the surface of the meter box 21, allowing the meter box 21 to cool down through heat exchange through its shell. The undulating sealing mechanism 35 of this application can be connected in series with the air intake assembly 4 and the circulating filter assembly 5 in the same circuit. When the undulating sealing mechanism 35 cuts off the inclined exhaust pipe 32, its circuit is disconnected, causing the air intake assembly 4 and the circulating filter assembly 5 to stop working. The undulating sealing mechanism 35 of this application can synchronously adjust the on / off state of the inclined exhaust pipe 32 according to water level changes using the buoyancy provided by the water level, allowing the inclined exhaust pipe 32 to synchronously open or close according to water level changes, effectively preventing rising water from entering the meter box 21 and effectively preventing water immersion problems of electrical components. The external exhaust pipe 34 provided in this application is combined with the circulating filter assembly 5, so as to remove the impurities filtered by the circulating filter assembly 5 through the heat dissipation airflow output by it, thereby restoring the filtering capacity of the circulating filter assembly 5.

[0035] Preferably, the outer exhaust pipe 341 of the external exhaust pipe 34 is sleeved on the output end of the inclined exhaust main pipe 32. More preferably, an inner exhaust pipe 342 is also inserted into the end of the outer exhaust pipe 341 away from the inclined exhaust main pipe 32. Preferably, a first limiting spring 343 is also sleeved on the outer wall of the inner exhaust pipe 342 to limit its initial relative position with the outer exhaust pipe 341. Preferably, a first magnetic metal ring 344 is also provided at the end of the inner exhaust pipe 342 outside the outer exhaust pipe 341. The exhaust inner pipe 342 provided in this application can change its length extending beyond the exhaust outer pipe 341 when the annular electromagnet 55 on the collar 53 is energized and magnetized. This effectively and automatically completes the docking of the exhaust inner pipe 342 and the collar 53, allowing the cooling airflow output from the exhaust inner pipe 342 to effectively pass through the collar 53. When the cooling airflow passes in the reverse direction through the filter unit 54 inside the collar 53, it can effectively clean the impurities intercepted by the filter unit 54, thereby cleaning the filter unit 54 and restoring its filtering capacity. The first limiting spring 343 provided in this application can push the exhaust inner pipe 342 to a reset movement when the annular electromagnet 55 is not pulling the first magnetic metal ring 344, causing the exhaust inner pipe 342 to separate from the collar 53, thus facilitating the replacement of the collar 53.

[0036] Preferably, the undulating sealing mechanism 35 includes a first mounting groove 351 and a second filling groove 352, which are connected to the inclined exhaust pipe 32 and respectively disposed below and above the inclined exhaust pipe 32. Preferably, a guide groove 354 is formed on the inner bottom surface of the first mounting groove 351. More preferably, a buoyancy block 353 capable of lifting and moving is embedded in the first mounting groove 351. Preferably, a guide rod 355 capable of being inserted into the guide groove 354 is connected to the bottom surface of the buoyancy block 353. More preferably, a drain hole is also provided on the bottom side of the first mounting groove 351 to drain the water accumulated in its cavity. Specifically, when the external water level rises, water gradually enters the first placement tank 351 through the drain hole and the inclined vent pipe 32, causing the water level in the first placement tank 351 to gradually rise. This causes the buoyancy block 353, made of a material with high buoyancy such as foam, to gradually rise and move into the inclined vent pipe 32. As the buoyancy block 353 rises further, it partially embeds itself into the second filling tank 352, thus cutting off the inclined vent pipe 32 and preventing external water from entering the meter box 21 through it. During the raising and lowering of the buoyancy block 353, the guide sub-slot 354 and the guide rod 355 cooperate to maintain the direction of raising and lowering, thereby ensuring the accuracy of the insertion of the buoyancy block 353.

[0037] Preferably, the air intake assembly 4 includes a first vertical short pipe 41, a second horizontal pipe 42, and a third vertical long pipe 43 that can cooperate to form a U-shaped tube. Preferably, the third vertical long pipe 43 is detachably mounted on the box cover 22. More preferably, the upper axial end of the third vertical long pipe 43 passes through the box cover 22 and communicates with the cavity of the meter box 21. Preferably, the first vertical short pipe 41 is connected to the third vertical long pipe 43 through a positioning connecting rod 44. More preferably, an air pump capable of guiding the airflow in a directional direction is also provided inside the third vertical long pipe 43. The first vertical short pipe 41 provided in this application allows the air inlet to be far away from the air outlet, thereby facilitating the effective cooling of electrical components by drawing in external cold air. The third vertical long pipe 43 provided in this application allows the airflow to flow from the upper part to the lower part of the meter box 21, thereby passing through the entire internal cavity space of the box, to ensure the sufficiency and effectiveness of heat transfer throughout the entire internal cavity of the box. The second horizontal pipe 42 provided in this application can cooperate with the circulating filter assembly 5, so that while directionally conveying airflow, the circulating filter assembly 5 can be used interchangeably to filter the airflow, ensuring the cleanliness of the input airflow and preventing impurities from covering the electrical components and hindering the heat dissipation of the electrical components.

[0038] Preferably, the inlet outer pipe 421 and outlet outer pipe 422 of the second horizontal pipe 42 are respectively connected to the output end of the first vertical short pipe 41 and the input end of the third vertical long pipe 43, thereby forming an insertion gap between the inlet outer pipe 421 and the outlet outer pipe 422 to accommodate the circulating filter assembly 5. Preferably, an inlet inner pipe 423 is elastically inserted into the end of the inlet outer pipe 421 away from the first vertical short pipe 41. More preferably, a second limiting spring 425 is sleeved on the inlet inner pipe 423 to limit its initial relative position with the inlet outer pipe 421. Preferably, an outlet inner pipe 424 is elastically inserted into the end of the outlet outer pipe 422 away from the third vertical long pipe 43. More preferably, a third limiting spring 426 is sleeved on the outlet inner pipe 424 to limit its initial relative position with the outlet outer pipe 422. Preferably, a second magnetic metal ring 427 is provided at the opposite ends of the inner intake pipe 423 and the outer exhaust pipe 422. The inner intake pipe 423 and the outer exhaust pipe 424 provided in this application can undergo a movement similar to that of the inner exhaust pipe 342 when the annular electromagnet 55 located between them is energized, thereby creating a smooth pipe cavity while ensuring the filtration of the airflow.

[0039] Preferably, the intermittent deflection motor 51 of the circulating filter assembly 5 is mounted on the cover 22. Preferably, a support rod 52 is circumferentially connected to the rotating shaft of the intermittent deflection motor 51. Preferably, a collar 53 is provided at the end of the support rod 52 away from the rotating shaft of the intermittent deflection motor 51. Preferably, a filter unit 54 is provided in the annular cavity of the collar 53, and annular electromagnets 55 are also provided at both ends of the collar 53. Preferably, the filter unit 54 can be a filter screen or a filter plate with an array of filter holes. More preferably, the filter holes on the filter plate have a gourd-shaped waist that facilitates the interception of impurities, and the gourd-shaped cavity can accelerate the airflow velocity and promote the reverse airflow to clear the filter holes and remove impurities. Specifically, the annular electromagnets 55 are alternately energized with the intermittent deflection motor 51, that is, they are in two parallel circuits and are connected by an opposite switch, thereby limiting their opposite on / off states.

[0040] Preferably, the detachable top cover 6 includes a top cover 61 and a cross 62 disposed below the top cover 61. More preferably, the bottom end of the cross 62 can be inserted into a second insertion positioning hole 213, thereby realizing the assembly connection between the detachable top cover 6 and the meter box 21. Preferably, the detachable top cover 6 is available in different specifications to accommodate smart meter bodies 2 with different lateral lengths.
