An integrated intelligent power metering box

Abstract

This invention belongs to the field of electricity metering technology, specifically an integrated intelligent electricity metering box, including a box body, protective components, an electricity metering module, a communication module, and an intelligent control module. The protective components include an annular protective plate disposed at the opening of the box body, with a flexible sealing strip disposed on the outer surface of the protective plate. By setting up the protective components, the incoming air is intercepted by the sealing strip and can only flow in through the air inlet hole disposed on the surface of the sealing strip, and fully contacts the drying particles inside the sealing strip. This promotes the full absorption of water vapor in the airflow by the drying particles, reducing the humidity of the incoming airflow. Thus, the dried cooling airflow is replenished to the inside of the box body, which fully cools the electrical components inside the box body while preventing the incoming airflow from carrying too much water vapor, which could threaten the safe operation of electrical structures such as smart meters.

Description

Technical Field

[0001] This invention belongs to the field of electricity metering technology, specifically an integrated intelligent electricity metering box. Background Technology

[0002] Integrated smart electricity metering boxes are a new type of metering device designed to meet the needs of smart grid construction and the development of the energy internet. They integrate functions such as electricity metering, data acquisition, remote communication, security protection, and status monitoring, serving as a key interface between electricity users and the power grid. Their core objective is to achieve digital, networked, and intelligent management of electricity metering, supporting accurate metering, lean operation and maintenance, and interactive services.

[0003] Integrated smart electricity metering boxes break through the limitations of traditional metering boxes that only "measuring". Through modular design, they integrate multiple functions, serving as both a "data acquisition terminal" for electricity metering and a "smart gateway" for interaction between the power grid and users. They mainly serve three major scenarios: electricity marketing (meter reading and billing), power distribution operation and maintenance (status monitoring and fault early warning), and user electricity management (energy consumption analysis and demand response).

[0004] When the integrated intelligent electricity metering box is working normally, it collects and measures the energy consumption of surrounding electrical equipment and transmits the data remotely to the data center. During normal operation, given the high humidity and temperature in the hot and humid summer environment, the heat released by the electrical components inside the electricity metering box accumulates inside. The near-enclosed environment inside the electricity metering box makes it difficult for the accumulated heat to be transferred to the outside, leading to excessively high internal temperature, which affects the normal operation of the electricity metering components and even increases the probability of overheating and combustion accidents inside the electricity metering box. Existing cooling technologies commonly used in the market, such as the installation of cooling fans, require direct airflow exchange between the box and the external environment. In humid environments, this can easily lead to moisture from the air brought in from the hot and humid external environment threatening the normal operation of the electrical components inside the box. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes an integrated intelligent power metering box.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention proposes an integrated intelligent power metering box, including a box body, a protective component, a power metering module, a communication module and an intelligent control module. The meter in the power metering module is arranged inside the box body, and the box body opening is provided with a rotatable closing door.

[0007] The protective components include an annular protective plate installed at the opening of the enclosure, a flexible sealing strip on the outer surface of the protective plate, and ventilation slots on the closed door corresponding to the sealing strip.

[0008] The hollow part inside the sealing strip is filled with dry granules. An air inlet is provided on the surface of the sealing strip near the ventilation slot, and an air outlet is provided on the side near the inside of the box. The air outlet communicates with the inside of the box. A cooling fan is also provided inside the box. The cooling fan is controlled by an intelligent control module to promote air exchange between the inside and outside of the box.

[0009] Preferably, a limiting groove is provided on the surface of the protective plate at the position corresponding to the sealing strip, the sealing strip slides into the limiting groove, and an air guide hole is provided on the inner wall of the limiting groove, the air guide hole connecting the limiting groove and the inside of the box;

[0010] The locating groove extends in a square shape, and a drive groove is provided on the inner wall of the locating groove near the right-angle turn. A drive roller is provided on the inner wall of the drive groove. The drive roller contacts the surface of the sealing strip and is controlled by a rotating device in the inner wall of the drive groove, which drives the sealing strip to rotate along the locating groove extension trajectory.

[0011] Preferably, impact blocks are uniformly arranged on the outer surface of the drive roller, and the ends of the impact blocks are tapered and in contact with the surface of the sealing strip.

[0012] Preferably, the cross-section of the sealing strip is elliptical, and the spacing between the openings of the limiting groove is less than the maximum diameter of the sealing strip cross-section, so that the sealing strip is confined inside the limiting groove.

[0013] Preferably, the cooling fan includes an intake fan and an exhaust fan, with the air vents concentrated in the area near the bottom and top of the protective plate, and the intake fan is located at the bottom of the housing, with the intake end of the intake fan communicating with the air vent near the bottom of the protective plate.

[0014] The exhaust fan is located at the top of the housing, and the exhaust end of the exhaust fan is connected to the air guide hole in the top area of ​​the protective plate.

[0015] Preferably, an annular air guide tube is provided in the middle of the inner part of the sealing strip, and the dry particles are distributed in the gap area between the air guide tube and the inner wall of the sealing strip.

[0016] An air outlet is provided on the side wall of the air guide tube at the location corresponding to the air outlet hole. The air outlet connects the air outlet hole and the interior of the air guide tube. The side wall of the air guide tube is uniformly provided with through holes, the diameter of which is smaller than the particle size of the dried particles.

[0017] Preferably, the protective plate is elastically connected to the inner wall of the box opening, and a vibration device is installed inside the protective plate, which is controlled by an external controller.

[0018] Preferably, the gap between the air guide tube and the inner wall of the sealing strip is also filled with rough-surfaced metal particles, which are mixed with the dry particles.

[0019] The beneficial effects of this invention are as follows:

[0020] The integrated smart electricity metering box described in this invention features a protective component that intercepts incoming air through a sealing strip, allowing it to flow in only through air inlets on the surface of the sealing strip. This airflow then comes into full contact with the drying particles inside the sealing strip, causing moisture in the airflow to be absorbed by the drying particles. This reduces the humidity of the incoming airflow, allowing the dried cooling airflow to replenish the box's interior. This effectively cools the electrical components inside the box while preventing excessive moisture from being introduced into the airflow, which could threaten the safe operation of the smart meter and other electrical structures.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] As shown in the attached diagram of the instruction manual. Figures 1-5 As shown, this application proposes an integrated intelligent electricity metering box, including a box body 1, a protective component 2, an electricity metering module 3, a communication module, and an intelligent control module. The electricity metering module 3 includes a metering chip, a current transformer, a calibration circuit, and an information storage device. The metered information can be displayed by a meter arranged on the inner wall of the box body 1, which is convenient for offline recorders to perform calibration. The box body 1 has a closed door 11 at its opening. The communication module passes through the side wall of the box body 1 with a communication wire to realize the data connection between the meter and external electrical equipment.

[0031] The protective component 2 includes an annular protective plate 21 disposed at the opening of the housing 1. A flexible sealing strip 22 is disposed on the surface of the protective plate 21 at the part of the gap between the protective plate 21 and the closed door 11. A ventilation groove 111 is disposed on the closed door 11 at the part corresponding to the sealing strip 22.

[0032] The hollow part inside the sealing strip 22 is filled with dry particles. An air inlet 221 is provided on the surface of the sealing strip 22 near the ventilation slot 111. The air inlet 221 is located on the outside of the close contact area between the sealing strip 22 and the sealing door 11, so that the airflow can only flow into the air inlet 221 after being intercepted at the close contact area. An air outlet 222 is provided on the side of the sealing strip 22 near the inside of the box 1, and the air outlet 222 communicates with the inside of the box 1. A cooling fan 12 is also provided inside the box 1. The cooling fan 12 is controlled by the intelligent controller in the intelligent control module to realize the air exchange between the inside and outside areas of the box 1. The diameter of the air inlet 221 and the air outlet 222 is smaller than the particle size of the dry particles. Or, if a larger diameter is set for processing convenience, a filter screen or filter cloth or other structure needs to be laid on the inner wall of the sealing strip 22 to prevent the dry particles from flowing out through the air inlet 221 or the air outlet 22.

[0033] Specific workflow: The electricity metering box operates normally, collecting and measuring the energy consumption of surrounding electrical equipment and transmitting the data remotely to the data center. During normal operation, given the high humidity and temperature in the hot and humid summer environment, the heat released by the electrical components such as the electricity metering module 3 inside the electricity metering box accumulates inside the box 1. The near-enclosed environment inside the box 1 makes it difficult for the accumulated heat to be transferred to the outside, resulting in excessively high internal temperature of the box 1, which affects the normal operation of the electrical components such as the electricity metering module 3, and may even increase the probability of overheating and combustion accidents inside the electricity metering box. Existing cooling technologies commonly used in the market, such as setting up cooling fans 12, require direct airflow exchange between the box 1 and the external environment. In a humid environment, this can easily lead to moisture from the air brought in from the hot and humid external environment threatening the normal operation of the electrical components inside the box 1.

[0034] Therefore, this application, by setting up protective component 2, ensures air exchange between the inner and outer areas of the enclosure 1, improves heat dissipation efficiency, and effectively prevents external moisture and impurities from penetrating inward and threatening the normal operation of the electrical components inside the enclosure 1. Specifically, during periods other than manual inspection or meter reading, the sealing door 11 at the opening of the enclosure 1 is kept closed. After closing, the back of the sealing door 11 is in close contact with the sealing strip on the protective plate 21, which can effectively prevent direct air exchange between the inner and outer environments of the enclosure 1, so that the inside of the enclosure 1 is in a nearly closed and safe environment.

[0035] A temperature and humidity sensor is installed inside the housing 1 to monitor the internal working environment in real time. When the internal temperature of the housing 1 is detected to be too high, the cooling fan 12 is activated to introduce the hot air inside the housing 1 to the outside, creating a negative pressure environment inside the housing 1. Under the action of the air pressure difference, outside air is forced to flow in through the gap between the closed door 11 and the opening of the housing 1. After being intercepted by the sealing strip 22, the flowing air can only flow in through the air inlet 221 set on the surface of the sealing strip 22. After passing through the gaps between the dry particles in the hollow area inside the sealing strip 22, it flows in along the air outlet 222 to replenish the interior of the housing 1, achieving... The continuous outward flow of air inside the enclosure 1 promotes air exchange between the inside and outside of the enclosure 1, accelerating the removal of heat generated during the operation of the electrical components inside the enclosure 1 and improving cooling efficiency. Furthermore, as the airflow passes through the enclosure 22, it comes into full contact with the dry particles inside the enclosure 22, thereby causing the water vapor in the airflow to be fully absorbed by the dry particles, reducing the humidity of the incoming airflow. This allows the dried cooling airflow to replenish the interior of the enclosure 1, effectively cooling the electrical components inside the enclosure 1 while preventing the incoming airflow from carrying in too much water vapor, which could threaten the safe operation of electrical structures such as smart meters.

[0036] Example 2:

[0037] Based on Embodiment 1, a limiting groove 211 is provided on the surface of the protective plate 21 corresponding to the sealing strip 22. The sealing strip 22 is slidably embedded in the limiting groove 211. An air guide hole 212 is provided on the inner wall of the limiting groove 211, and the air guide hole 212 connects the limiting groove 211 and the interior of the box 1. The sealing strip 22 protrudes from the surface of the protective plate 21 near the sealing door 11, so that when the sealing door 11 is closed, it can make close contact with the inner wall of the sealing door 11, intercepting the seepage airflow and allowing it to flow in only along the air inlet hole 221.

[0038] The limiting groove 211 extends in a square pattern, and a driving groove 213 is provided on the inner wall of the limiting groove 211 near the right-angle turn. A driving roller 23 is provided on the inner wall of the driving groove 213. The driving roller 23 contacts the surface of the sealing strip 22 and is controlled by a rotating device in the inner wall of the driving groove 213. The rotating device can be a miniature drive motor, the output end of which is connected to the driving roller 23, which can drive the sealing strip 22 to rotate along the extension trajectory of the limiting groove 211. Impact blocks 231 are evenly provided on the outer surface of the driving roller 23. The ends of the impact blocks 231 are tapered and contact the surface of the sealing strip 22. The sealing strip 22 is in a relaxed state in the driving groove 213 and is not restricted. This means that when the sealing strip 22 slides to the turn position and undergoes a right-angle deformation, it will not be hindered by the friction of the inner wall of the limiting groove 211, making the rotation smoother and reducing the wear on the inner wall of the sealing strip 22.

[0039] Specific workflow: Based on the specific workflow in Embodiment 1, in order to ensure the uniform distribution of humidity of the dry particles inside the sealing strip 22 and reduce the problem of local areas of dry particles absorbing too much moisture and failing, or even clumping due to excessive humidity affecting the uneven flow of air, this application sets the sealing strip 22 to slide into the limiting groove 211 provided on the surface of the protective plate 21. After working for a period of time, the rotating device located in the inner wall of the drive groove 213 is started at regular intervals, so that the output end of the rotating device drives the drive roller 23 to rotate, thereby driving the sealing strip 22 to slide along the annular limiting groove 211. During the sliding process, external vibration and the inertia of the internal dry particles cause the dry particles located inside the sealing strip 22 to move relative to the sealing strip 22, accelerating the exchange and flow of dry particles in different parts inside the sealing strip 22.

[0040] Especially when the various parts of the sealing strip 22 pass through the drive roller 23 at the right-angle turning position in sequence, the severe bending deformation of the sealing strip 22 and the squeezing impact of the conical impact block 231 on the drive roller 23 cause the dry particles filled in the hollow area inside the sealing strip 22 to be subjected to severe impact. On the one hand, it causes the dry particles in the hollow area inside the sealing strip 22 to flow faster. On the other hand, the impact causes the dry particles in the local area inside the sealing strip 22, which tend to agglomerate due to high humidity, to disperse due to the impact, so that the dry particles in the area inside the sealing strip 22 remain in a loose and dispersed state, thereby ensuring the passability of the area inside the sealing strip 22. Furthermore, because the extension trajectory of the limiting groove 211 is square, when the horizontal part of the sealing strip 22 rotates to become vertical, gravity causes the dry particles in the hollow area inside the sealing strip 22 to flow along the hollow area inside the sealing strip 22, further promoting the fluidity of the dry particles inside the sealing strip 22. This ensures that the degree of water vapor absorption by the dry particles in different areas inside the sealing strip 22 is similar, thereby improving the full utilization of the dry particles.

[0041] Example 3:

[0042] Based on Embodiment 2, the cross-section of the sealing strip 22 is elliptical, and the spacing of the openings of the limiting groove 211 is smaller than the maximum diameter of the cross-section of the sealing strip 22, so that the sealing strip 22 is confined inside the limiting groove 211.

[0043] Specific workflow: Based on the specific workflow in Embodiment 2, to avoid the situation where the sealing strip 22 undergoes significant relative rotational deformation and twisting inside the limiting groove 211, resulting in increased friction between it and the inner wall of the limiting groove 211, thus affecting the sliding of the sealing strip 22 along the limiting groove 211, the sealing strip 22 is designed with an elliptical flat structure in cross-section, and the limiting groove 211 is also approximately elliptical in cross-section. Furthermore, the opening of the limiting groove 211 is smaller than the maximum diameter of the sealing strip 22's cross-section. This prevents the sealing strip 22 from detaching from the limiting groove 211 due to deformation when sliding along the inner wall of the limiting groove 211. Similarly, the interlocking of the elliptical sealing strip 22 and the limiting groove 211 also prevents the sealing strip 22 from rotating around the extension trajectory of the limiting groove 211 during its sliding along the limiting groove 211, ensuring the smooth sliding of the sealing strip 22 along the limiting groove 211.

[0044] Furthermore, in order to make the sealing strip 22 slide more smoothly along the limiting groove 211, the part of the sealing strip 22 near the sealing door 11 can be made of elastic material, and the other parts can be made of elastic metal hose material with a smooth surface. Lubricating oil is also applied to the inner wall of the limiting groove 211 to improve the sealing of the gap and make the sealing strip 22 slide more smoothly.

[0045] Example 4:

[0046] Based on Embodiment 3, the cooling fan 12 includes an intake fan 121 and an exhaust fan 122. The air guide holes 212 are concentrated in the area near the bottom and top of the protective plate 21, and the ventilation slots 111 are also distributed in the area near the top and bottom of the closed door 11. The intake fan 121 is located at the bottom of the box 1, and the intake end of the intake fan 121 communicates with the air guide hole 212 near the bottom of the protective plate 21. The exhaust fan 122 is located at the top of the box 1, and the exhaust end of the exhaust fan 122 communicates with the air guide hole 212 in the top area of ​​the protective plate 21.

[0047] Specific workflow: Based on the specific workflow in Example 3, the bottom and top areas where the air guide holes 212 on the inner wall of the upper limit groove 211 of the protective plate 21 are concentrated are set as the air inlet area and the air outlet area, respectively; for the sealing strip 22 in the air inlet area, due to the action of the air intake fan 121 inside the box 1, the air guide hole 212 connected to the air intake end of the air intake fan 121 will have negative pressure, which will cause the outside air to flow into the sealing strip 22 corresponding to the air inlet area at an accelerated speed. After the drying particles absorb water and are dried, they are drawn in by the air intake end of the air intake fan 121 and then flow into the box 1 from the air outlet end of the air intake fan 121. Inside the box 1, they are flushed from bottom to top, carrying away the heat generated by the electrical components inside the box 1 and the water vapor that may have seeped in;

[0048] When the hot airflow flows into the top of the housing 1, it is drawn in by the exhaust fan 122, and then flows out from the exhaust end of the exhaust fan 122 into the corresponding air guide hole 212 of the exhaust area, and then flows into the interior of the sealing strip 22 of the exhaust area. After passing through the gaps between the dry particles, it flows out to the outside through the air inlet 221. The process of the hot airflow passing through the sealing strip 22 of the exhaust area can wash and dry the sealing strip 22 inside the exhaust area, so that the water vapor adsorbed by the dry particles inside the sealing strip 22 of the exhaust area evaporates under the heating effect of the hot airflow and flows to the outside with the airflow, thereby restoring the water absorption and drying effect of the dry particles inside the sealing strip 22 of the exhaust area.

[0049] Furthermore, the sealing strips 22 of the air inlet area and the air outlet area are separated by the vertical sealing strips 22 and the tightly contacting and squeezing drive rollers 23 at the corners, making it difficult for the inflowing airflow and the outflowing airflow to interfere with each other inside the sealing strips 22, thus ensuring that the working process of the air inlet area and the air outlet area can proceed normally.

[0050] Therefore, by starting the rotating device at regular intervals, the air inlet area and the sealing strip 22 part that absorbs more moisture are moved to the air outlet area. The sealing strip 22, which keeps the dry particles inside the air outlet area in a dry and dispersed state, is moved to the air outlet area. This allows the moisture absorbed by the dry particles from the inflowing airflow to be carried away by the outflowing airflow, thereby increasing the continuous working cycle of the sealing strip 22 and reducing the situation where the dry particles in the local area inside the sealing strip 22 absorb too much moisture and cannot work properly.

[0051] Example 5:

[0052] Based on Example 4, an annular air guide tube 24 is provided in the middle of the inner part of the sealing strip 22. The dried particles are distributed in the gap area between the air guide tube 24 and the inner wall of the sealing strip 22. An air outlet tube 241 is provided on the side wall of the air guide tube 24 at the part corresponding to the air outlet 222. The air outlet tube 241 connects the air outlet 222 and the interior of the air guide tube 24. The side wall of the air guide tube 24 is uniformly provided with through holes, and the diameter of the through holes is smaller than the particle size of the dried particles.

[0053] Specific workflow: Based on the specific workflow in Embodiment 4, in order to improve the efficiency of airflow passing through the interior of the sealing strip 22, an air guide pipe 24 is set inside the sealing strip 22. The cross-sectional area of ​​the air guide pipe 24 is less than half of the cross-section of the hollow area inside the sealing strip 22, and the dry particles are evenly distributed in the gap area between the air guide pipe 24 and the inner wall of the sealing strip 22. In this way, in the air inlet area, the negative pressure effect of the air guide hole 212 is directly transmitted to the interior of the air guide pipe 24, so that the airflow flowing from the outside into the gap of the dry particles can quickly pass through the through hole set in the side wall of the air guide pipe 24 after contacting the dry particles and being dried by water absorption, and then flow along the air outlet pipe 241 on the side wall of the air guide pipe 24 to the air guide hole 212, and then flow into the interior of the box 1, thereby improving the efficiency of airflow passing through the gap of the dry particles to participate in the air cooling treatment inside the box 1.

[0054] Furthermore, for the air outlet area, the outflowing hot airflow, after passing through the air guide hole 212 and the air outlet pipe 241, flows directly into the gap between the dry particles inside the corresponding sealing strip 22. The function of the air guide pipe 24 is to make the distribution of the dry hot airflow more uniform. After flowing out, it comes into full contact with the dry particles in the gap area between the air guide pipe 24 and the inner wall of the sealing strip 22, so that the water vapor absorbed by the dry particles in the gap area is fully carried away by the outflowing dry hot airflow. In this way, when these dry particles move to the air inlet area later, they can play a normal role in purifying and drying the incoming airflow, improving the continuous working characteristics of the sealing strip 22.

[0055] Furthermore, when the sealing strip 22 slides along the inside of the limiting groove 211, the difference in speed and deformation amplitude between the air guide tube 24 and the sealing strip 22 during the movement causes the dry particles filled in the gap area to be squeezed and impacted, which promotes the flowability of the dry particles and further prevents them from agglomerating together.

[0056] Example 6:

[0057] Based on Embodiment 5, the protective plate 21 and the inner wall of the opening of the box 1 are elastically connected. There are various possible implementation schemes for the elastic connection. Any scheme that can achieve relative vibration between the protective plate 21 and the opening of the box 1 is applicable to this application. For example, the outer edge of the square ring structure of the protective plate 21 connected to the inner wall of the opening of the box 1 can be made of elastic material. Alternatively, a limiting rod on the edge of the protective plate 21 can be slidably embedded into a limiting hole provided on the inner wall of the opening of the box 1, and a spring can be provided between the limiting rod and the limiting hole. In this way, when the vibration device is started, the limiting rod drives the protective plate 21 to perform a small-amplitude high-frequency lateral vibration along the limiting hole. Furthermore, a vibration device is provided inside the protective plate 21. The vibration device can be a miniature vibration motor, etc., and the vibration device is controlled by an external controller.

[0058] Specific workflow: Based on the specific workflow in Example 5, when the cooling fan 12 is started, the vibration device can be started at regular intervals to drive the protective plate 21 to vibrate elastically. Because the surface of the sealing strip 22 maintains close contact with the inner wall of the sealing door 11, the elastic vibration causes the contact part of the sealing strip 22 on the protective plate 21 to move at a high frequency and a small amplitude with the sealing door 11, so that the sealing strip 22 is subjected to vibration and compression. The size of the hollow area inside the sealing strip 22 changes continuously, causing the air in the gap between the dry particles inside to accelerate and impact along the gap between the dry particles during the vibration and compression process, improving the air exchange between the inner and outer areas, and promoting the fluidity of the dry particles while increasing the contact degree between the dry particles and the inflow airflow.

[0059] Example 7:

[0060] Based on Example 6, the gap between the inner wall of the air guide tube 24 and the sealing strip 22 is also filled with rough-surfaced metal particles, specifically iron sand particles; the metal particles are mixed with the dry particles, and the amount of metal particles is less than that of the dry particles.

[0061] Specific workflow: Based on the specific workflow in Example 6, as the sealing strip 2 rotates along the inside of the limiting groove 211, the vibrator is activated to cause the sealing strip 2 to vibrate. During this process, the metal particles and the dry particles come into contact and impact each other. The rough surface of the metal particles scrapes the surface of the dry particles, carrying away the dust and impurities adhering to the surface of the dry particles. If the dry particles are non-metallic dry particles such as silica gel desiccant, the top area of ​​the protective plate 21 can be made of a conductive metal material and grounded. In this way, when the dry particles adsorb dust in the airflow due to electrostatic properties, they move to the outlet area and are affected by the conductivity of the metal particles and the outlet area of ​​the protective plate 21, so that the static electricity is discharged, reducing the adsorption of dust and impurities by the dry particles, and the cleaned dust and impurities are carried away by the scouring action of the outflowing airflow, improving the cleaning effect of the dry particles.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
