Description

Technical Field

[0001] This invention relates to the field of electricity metering box technology, and in particular to a highly protected integrated electricity metering box for use in smart grids. Background Technology

[0002] With the deepening of smart grid construction, the functional positioning of electricity metering boxes, as a key node at the end of the power supply chain, has undergone a fundamental transformation. Traditional metering boxes only need to house basic components such as electricity meters, switches, and fuses to achieve electricity metering and circuit protection. Modern smart metering boxes, however, further integrate a large number of sophisticated electronic devices such as intelligent data acquisition terminals, communication modules, and edge computing units, undertaking intelligent tasks such as remote meter reading, load identification, fault diagnosis, and line loss analysis. This trend towards intelligent development has significantly increased the integration and value density of electronic components within the enclosure, placing extremely stringent requirements on the operating environment. Precision electronic devices are far more sensitive to temperature, humidity, and cleanliness than traditional electrical components. Any deterioration of the microenvironment within the enclosure can trigger a chain reaction of faults, including data acquisition distortion, communication interruptions, and control failures, thereby affecting the reliable operation of the entire smart grid's end-point system. However, in the actual operating environment of damp and dusty outdoor environments, the protective capabilities of existing metering boxes are insufficient to meet the high environmental requirements of intelligent equipment. While ventilation and heat dissipation channels meet heat dissipation needs, they also become pathways for dust and moisture to intrude. Dust accumulation forms an insulation layer, leading to a continuous decline in heat dissipation efficiency and accelerating device aging; moisture condensation causes electrochemical corrosion and reduced insulation strength, resulting in serious faults such as creepage and flashover. Although adding filters can block some dust, the filters themselves rely on regular manual maintenance, and once clogged, they exacerbate heat dissipation deterioration.

[0003] In summary, intelligent upgrades have elevated the requirements for the internal microenvironment of energy metering boxes from "rough protection" to "precise control." Traditional, single dustproof or moisture-proof structures are no longer sufficient to meet the stringent reliability demands of smart grid end-point equipment. Therefore, there is an urgent need for a highly protective integrated energy metering box capable of active dust removal, efficient dehumidification, and self-maintenance to fundamentally ensure the long-term stable operation of smart grid end-point equipment in harsh outdoor environments.

[0007] In one embodiment, the porous, high thermal conductivity condensate is specifically a sponge copper with an anti-corrosion coating on its outer surface.

[0008] In one embodiment, the condensate recycling cleaning mechanism further includes a cable chain liquid supply assembly and a fluid distributor.

[0010] In one embodiment, a motor is fixedly mounted on one side of the reciprocating cleaning rack, and the output shaft of the motor is fixedly connected to one side of the reciprocating lead screw via a coupling.

[0011] In one embodiment, an anti-erosion and splashing baffle is fixedly installed inside the mounting housing. The anti-erosion and splashing baffle is disposed between the filter screen and the air inlet. A plurality of condensation interception plates are fixedly installed inside the mounting housing. The plurality of condensation interception plates are staggered and disposed on one side of the air outlet surface of the porous high thermal conductivity condensate.

[0012] In one embodiment, a temperature and humidity sensor is installed inside the mounting housing, a water level sensor is installed inside both the water storage chamber and the sludge collection chamber, a sludge discharge assembly is fixedly installed inside both the water storage chamber and the sludge collection chamber, and a pressure sensor is installed on both sides of the filter screen.

[0013] In one embodiment, an exhaust mechanism is fixedly installed on the top of the housing. The exhaust mechanism includes a second fan and a dust cover. The second fan is fixedly installed on the top of the housing, and the dust cover is disposed on top of the second fan.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention; 1. Addressing the problem mentioned in the background art of insufficient protection levels in existing metering boxes, making them vulnerable to the dual erosion of outdoor dust and moisture, this invention proposes an active environmental protection architecture. By placing the filter at the front and the condensation-type thermal management mechanism at the rear, a tiered air conditioning strategy of "dust removal first, dehumidification later" is constructed. Before entering the core area of ​​the box, outside air must first pass through the filter to intercept dust, and then pass through a porous, high-thermal-conductivity condenser to remove moisture. This design transforms the traditional metering box's "passive" protection mode into an "active" purification isolation barrier, decoupling the internal microenvironment from harsh external conditions at the source. This directly provides a clean and dry operating space for the increasing number of precision electronic components, significantly improving the overall protection level of the power metering box from the system architecture level.

[0016] 2. The condensate recycling and cleaning mechanism utilizes the condensate generated during dehumidification to automatically flush the filter screen in reverse using a high-pressure pump and nozzles. This design completely eliminates the potential for filter screen clogging, which can lead to ventilation and heat dissipation failure. It ensures the long-term effectiveness of the heat dissipation channels and avoids internal overheating failures caused by untimely filter screen maintenance. From the perspective of long-term reliable system operation, this design enhances the high protection performance of the metering box.

[0017] 3. By completely sealing and isolating the sewage collection chamber and water storage chamber through an anti-interference mechanism, a safe water management system of "clean water source and sewage separation" is constructed. This structure not only eliminates cross-contamination of the cleaning pipeline by sewage, but also physically prevents accidental liquid spillage or splashing onto live components, eliminating major safety hazards such as internal short circuits and creepage. This design, which proactively prevents secondary disasters caused by liquids from the inside, elevates the protection level of the power metering box to a new level. Attached Figure Description

Detailed Implementation

[0021] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0022] like Figure 1-5 As shown, the present invention provides a technical solution: a high-protection integrated power metering box for smart grids, comprising a box body 1, a condensation-type thermal management mechanism 3, and a condensate recycling and cleaning mechanism 4. An air inlet mechanism 2 is fixedly installed at the bottom of the box body 1. The box body 1 serves as the main support for the entire power metering box. The air inlet mechanism 2 includes a mounting shell 201, with an air inlet 202 on one side for introducing external air. A first fan 203 is installed at the top of the mounting shell 201 to drive air in through the air inlet 202 and then blown into the box body 1 from the top of the mounting shell 201. A filter screen 5 is fixedly installed inside the mounting shell 201 to filter external air. The condensation-type thermal management mechanism 3 includes a semiconductor cooling chip 301. A porous high-thermal-conductivity condensate body 304 is provided on the cold end side of the semiconductor cooling chip 301. The semiconductor cooling chip 301 lowers the temperature of the porous high-thermal-conductivity condensate body 304, thereby reducing the temperature of the air passing through the porous high-thermal-conductivity condensate body 304. The temperature is adjusted so that water vapor in the air condenses on the outer wall of the porous high thermal conductivity condensate body 304. The porous high thermal conductivity condensate body 304 is installed in the air duct inside the mounting housing 201. The filter screen 5 is installed upstream of the porous high thermal conductivity condensate body 304 along the airflow direction. The mounting housing 201 has a water storage chamber 205 for storing the condensate generated by the condensation-type thermal management mechanism 3. The condensate recycling and cleaning mechanism 4 is installed between the filter screen 5 and the air inlet 202 for condensate recycling and cleaning. Mechanism 4 includes a high-pressure pump 401. The inlet of the high-pressure pump 401 is connected to the interior of the water storage chamber 205 through a pipeline. The outlet of the high-pressure pump 401 is connected to several nozzles 404. The high-pressure pump 401 draws out the condensate inside the water storage chamber 205 and sprays it out through the nozzles 404 to clean the filter screen 5. Several nozzles 404 are set on the air outlet side of the filter screen 5. The inside of the mounting shell 201 is provided with a dirt collection chamber 204 for storing the wastewater generated during the cleaning of the filter screen 5.

[0023] Please refer to further information. Figure 4In this embodiment, the specific structure of the condensation-type thermal management mechanism 3 is as follows: A heat spreader 302 is fixedly connected to the cold end side of the semiconductor cooling chip 301. A plurality of heat exchange tubes 303 are fixedly installed on one side of the heat spreader 302. The plurality of heat exchange tubes 303 are embedded in the interior of the porous high thermal conductivity condensate body 304 to efficiently and uniformly conduct cold energy to all the pore surfaces of the porous high thermal conductivity condensate body 304. A heat-conducting fin 305 is fixedly connected to the hot end of the semiconductor cooling chip 301. A cooling fan 306 is fixedly installed on one side of the heat-conducting fin 305 to force the heat from the hot end to be discharged.

[0024] Preferably, the porous, high thermal conductivity condensate 304 is a sponge copper with an anti-corrosion coating on its outer surface. Its three-dimensional interconnected pore structure provides a huge condensation surface area, while the anti-corrosion coating solves the problem of oxidation and corrosion of copper in long-term humid environments, eliminating the risk of oxide shedding and clogging subsequent nozzles 404.

[0025] like Figure 5 As shown, the condensate recycling cleaning mechanism 4 also includes a cable chain liquid supply assembly 402 and a fluid distributor 403. The inlet end of the cable chain liquid supply assembly 402 is fixedly connected to the outlet end of the high-pressure pump 401, and the outlet end of the cable chain liquid supply assembly 402 is fixedly connected to the inlet end of the fluid distributor 403. Several nozzles 404 are fixedly connected to one side of the fluid distributor 403. The cable chain liquid supply assembly 402 is used to provide a reliable and flexible fluid connection between the high-pressure pump 401 and the fluid distributor 403 when the fluid distributor 403 reciprocates. To achieve full coverage cleaning of filter 5 by nozzle 404, please refer to [link / reference needed]. Figure 6 The condensate recycling cleaning mechanism 4 also includes a reciprocating cleaning frame 405. A reciprocating screw 407 is rotatably installed inside the reciprocating cleaning frame 405. A guide rod 406 is fixedly installed inside the reciprocating cleaning frame 405. A fluid distributor 403 is slidably installed inside the reciprocating cleaning frame 405 via the guide rod 406. The fluid distributor 403 is threadedly connected to the outer wall of the reciprocating screw 407. When the reciprocating screw 407 rotates, it can drive the fluid distributor 403 to reciprocate along the axial direction of the guide rod 406.

[0026] Please see Figure 6 A motor 408 is fixedly installed on one side of the reciprocating cleaning rack 405. The output shaft of the motor 408 is fixedly connected to one side of the reciprocating lead screw 407 through a coupling to provide rotational power.

[0027] Please see Figure 3 To prevent wastewater from splashing onto the outside of the air inlet 202 during the cleaning process, an anti-scouring and splashing baffle 207 is fixedly installed inside the mounting housing 201. The anti-scouring and splashing baffle 207 is set between the filter screen 5 and the air inlet 202, forming a physical barrier.

[0028] In addition, please see Figure 3 To intercept residual condensate droplets that may be carried by the air outlet surface of the porous high thermal conductivity condensate 304, a number of condensate interception plates 208 are fixedly installed inside the mounting shell 201. The condensate interception plates 208 are staggered on one side of the air outlet surface of the porous high thermal conductivity condensate 304. The airflow flows tortuously between the staggered condensate interception plates 208. The water droplets are separated due to inertial impact on the plate wall, and the dry air passes smoothly into the box.

[0029] To enhance the level of intelligence, a temperature and humidity sensor is installed inside the housing 201 to monitor the internal environment in real time. Water level sensors are installed inside both the water storage chamber 205 and the sludge collection chamber 204. When the water level sensor in the water storage chamber 205 detects that the liquid level has reached a preset high value, the controller can start the high-pressure pump 401 to clean the filter screen 5 using the accumulated condensate, thereby consuming the stored water and lowering the liquid level. If the liquid level remains high, excess condensate can be discharged through the sludge discharge assembly 206 located at the bottom of the water storage chamber 205. When the water level sensor in the sludge collection chamber 204 detects that the liquid level has reached a preset high value, the controller can issue an alarm to prompt maintenance personnel to clean the sludge collection chamber 204 in a timely manner. Alternatively, wastewater can be centrally discharged through the sludge discharge assembly 206 located at the bottom of the sludge collection chamber 204. The two sets of sewage discharge components 206 are independent and controlled separately to ensure that the discharge paths of clean condensate and dusty sewage are completely isolated, preventing cross-contamination. Both sides of the filter screen 5 are equipped with air pressure sensors to determine whether the filter screen 5 needs cleaning by monitoring the air pressure on both sides of the filter screen 5.

[0030] To form a complete ventilation circuit, please refer to Figure 2 The top of the housing 1 is fixedly installed with an exhaust mechanism 6. The exhaust mechanism 6 includes a second fan 601 and a dust cover 602. The second fan 601 is fixedly installed on the top of the housing 1, and the dust cover 602 is set on top of the second fan 601 to exhaust hot air inside the housing and prevent external dust from flowing back in from the exhaust port.

[0031] Please see Figure 3-7This embodiment also includes two sets of anti-interference mechanisms 7, which are fixedly installed on the top of the sludge collection chamber 204 and the water storage chamber 205, respectively, for fully enclosing the top space of the two tanks and precisely controlling the inflow path of the liquid. The anti-interference mechanism 7 includes a sealing plate 701, which completely seals the top space of the sludge collection chamber 204 or the water storage chamber 205. Several one-way liquid passing components 702 are fixedly installed in the middle section of the sealing plate 701. The one-way liquid passing components 702 are the only liquid channels that penetrate the thickness of the sealing plate 701. In other words, during the operation of this invention, the condensate generated by the condensation-type thermal management mechanism 3 and the dust-laden wastewater generated by the condensate recycling cleaning mechanism 4 after cleaning the filter screen 5 can only enter the water storage chamber 205 and the dirt collection chamber 204 respectively through the corresponding one-way liquid flow assembly 702, and cannot flow in from any other gaps. The top of the sealing plate 701 is provided with a guide groove 703, which is located on one side of the one-way liquid flow assembly 702. When liquid drips or splashes onto the upper surface of the sealing plate 701, the liquid will flow along the guide groove under the action of gravity. The sloping water of 703 automatically flows and converges, and is guided to the inlet of the one-way liquid flow component 702. Finally, it flows into the tank below through the one-way liquid flow component 702. The clean condensate and the dusty cleaning wastewater are strictly isolated and collected by their respective anti-interference mechanisms 7, eliminating the possibility of contamination of the clean water source and ensuring that the cleaning water drawn by the high-pressure pump 401 is always clean. The fully enclosed tank space minimizes the secondary evaporation loss of condensate and prevents accidental liquid overflow caused by tilting or vibration of the tank 1, thus protecting the electrical safety inside the tank.

[0032] This invention addresses the problem mentioned in the background art: the existing metering boxes lack sufficient protection and are unable to withstand the dual erosion of outdoor dust and moisture. It proposes an active environmental protection architecture. By placing the filter 5 at the front and the condensation-type thermal management mechanism 3 at the rear, a tiered air conditioning strategy of "dust removal first, dehumidification later" is constructed. Before entering the core area of ​​the box 1, outside air must first pass through the filter 5 to intercept dust, and then pass through the porous, high-thermal-conductivity condenser 304 to condense and remove moisture. This design transforms the traditional metering box's "passive" protection mode into an "active" purification isolation barrier, decoupling the internal microenvironment from harsh external conditions at the source. This directly provides a clean and dry operating space for the increasing number of precision electronic components, significantly improving the overall protection level of the power metering box from the system architecture level. The condensate recycling and cleaning mechanism 4 uses the condensate generated by dehumidification to automatically flush the filter screen 5 in reverse through a high-pressure pump 401 and a nozzle 404. This design completely eliminates the hidden danger of filter screen clogging leading to ventilation and heat dissipation failure, ensures the long-term effectiveness of the heat dissipation channel, avoids internal overheating failure caused by untimely filter screen maintenance, and enhances the high protection performance of the metering box from the perspective of long-term reliable operation of the system. By completely sealing and isolating the sewage collection chamber 204 and the water storage chamber 205 through the anti-interference mechanism 7, a safe water management system with "clean water source and sewage separation" is constructed. This structure not only eliminates cross-contamination of the cleaning pipeline by sewage, but also physically prevents accidental liquid spillage or splashing onto live components, eliminating major safety hazards such as internal short circuits and creepage. This design, which proactively prevents secondary disasters caused by liquids from the inside, elevates the protection level of the power metering box to a new level.

[0033] Operating principle: Driven by the first fan 203, external air enters the mounting housing 201 through the air inlet 202. It first passes through the filter screen 5 to remove dust, and the clean air continues to flow downstream to the porous, high-thermal-conductivity condensate body 304. The cooling capacity of the semiconductor cooling chip 301 is conducted to the porous, high-thermal-conductivity condensate body 304 via the heat spreader 302 and heat exchange tubes 303, lowering its temperature below the dew point. As the air flows through its three-dimensional pores, it is fully cooled, and water vapor condenses into liquid droplets. Under gravity, these droplets fall and are collected in the water storage chamber 205 via the guide channel 703 on the sealing plate 701 and the one-way liquid flow assembly 702. The dehumidified and cooled air passes through the staggered condensation interception plates 208, where any residual water droplets may be trapped. It then enters the housing 1 to provide a clean and dry environment for the electronic components and is finally discharged by the exhaust mechanism 6. When the system determines that the filter screen 5 needs cleaning, the high-pressure pump 401 starts, drawing clean condensate from the water storage chamber 205 and delivering it to the fluid distributor 403 via the drag chain liquid supply assembly 402. Several nozzles 404 then perform a reverse high-pressure rinse from the air outlet side of the filter screen 5. Simultaneously, the motor 408 drives the reciprocating screw 407 to rotate, causing the fluid distributor 403 to reciprocate along the guide rod 406, enabling the nozzles 404 to perform a full-width scanning clean of the filter screen 5. The dust-laden wastewater generated during rinsing is blocked by the anti-scouring splash baffle 207 and flows into the collection chamber 204 for storage via the guide channel 703 at the top of the collection chamber 204 and the one-way liquid flow assembly 702. Regarding liquid level management, when the water level sensor in the water storage chamber 205 detects that the liquid level has reached a preset high value, the controller prioritizes starting the high-pressure pump 401 to perform a filter cleaning to consume the stored water. If the liquid level remains high, the drain assembly 206 at the bottom of the water storage chamber 205 will be opened to discharge excess clean condensate. When the water level sensor in the sludge collection chamber 204 detects that the liquid level has reached a preset high value, the controller issues an alarm to prompt maintenance personnel to clean the chamber. Alternatively, the sludge can be discharged centrally by opening the drain assembly 206 at the bottom of the sludge collection chamber 204. The two drain assemblies 206 operate independently, ensuring that clean water and wastewater are discharged separately, preventing cross-contamination, and thus completing a complete closed-loop cycle from dehumidification and condensation to filter self-cleaning and safe discharge of waste liquid.
