Description
Technical Field
[0001] The invention belongs to the technical field of electric energy metering, in particular to an integrated intelligent electric energy metering box. Background Art
[0002] The integrated smart energy meter box is a new type of metering device designed to meet the needs of smart grid construction and the development of the energy internet. It integrates energy metering, data collection, remote communication, security protection, and status monitoring. It serves as a key interface between power users and the power grid. Its core goal is to achieve digital, networked, and intelligent management of energy metering, supporting precise metering, lean operations and maintenance, and interactive services.
[0003] The integrated intelligent electricity meter box breaks the limitation of "simple metering" of traditional meter boxes. Through modular design, it integrates multiple functions. It is not only a "data collection terminal" for electricity metering, but also an "intelligent gateway" for interaction between the power grid and users. It mainly serves three scenarios: power marketing (meter reading, billing), distribution operation and maintenance (status monitoring, fault warning), and user electricity management (energy consumption analysis, demand response).
[0004] When the integrated intelligent electricity meter box is working normally, it collects and measures the energy consumption of the surrounding electric energy equipment and transmits it remotely to the data center. During the above normal working process, due to the high humidity and high temperature in the hot and humid environment in summer, the heat released by the electrical components inside the electricity meter box during operation accumulates inside the electricity meter box. The nearly closed environment inside the electricity meter box makes it difficult for the accumulated heat to be transferred to the outside world, resulting in the internal temperature of the electricity meter box being too high, affecting the normal operation of the electricity metering components, and even increasing the probability of overheating and combustion accidents inside the electricity meter box. The cooling technical means commonly adopted in the existing market, such as setting up cooling fans and other structures, require that the box maintain direct airflow exchange with the external environment. This can easily cause the water vapor in the air brought in from the hot and humid external environment to threaten the normal operation of the electrical components inside the box in a humid environment.

DETAILED DESCRIPTION
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings shown in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1: As shown in the accompanying drawings Figure 1-Figure 5As shown, the present application proposes an integrated intelligent electric energy metering box, comprising a box body 1, a protective component 2, an electric energy metering module 3, a communication module and an intelligent control module. The electric energy metering module 3 comprises a metering chip, a mutual inductor, a calibration circuit and an information storage device. The collected 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 opening of the box body 1 is provided with a closed door 11. The communication module passes through the side wall of the box body 1 through a communication wire to realize data connection between the meter and the external electric energy equipment. The protection assembly 2 includes an annular protection plate 21 disposed at the opening of the box body 1. A flexible sealing strip 22 is disposed on the surface of the protection plate 21 at the gap between the protection plate 21 and the closed door 11. A ventilation slot 111 is disposed on the closed door 11 at a position corresponding to the sealing strip 22. The hollow part inside the closing strip 22 is filled with dry particles, and an air inlet 221 is provided on the surface of the closing strip 22 on one side close to the ventilation slot 111. The air inlet 221 is located on the outside of the close contact part between the closing strip 22 and the closing door 11, so that the air flow can only flow into the air inlet 221 after being intercepted at the close contact part; an air outlet 222 is provided on the side of the closing strip 22 close to the inside of the box body 1, and the air outlet 222 is communicated with the inside of the box body 1; a cooling fan 12 is also provided inside the box body 1, and the cooling fan 12 is controlled by the intelligent controller in the intelligent control module to realize air exchange between the inside and outside areas of the box body 1; and the apertures of the air inlet 221 and the air outlet 222 are both smaller than the particle size of the dry particles, or when a larger aperture is set for processing convenience, a filter screen or filter cloth or other structures need to be laid on the inner wall of the closing strip 22 to prevent the dry particles from flowing out through the air inlet 221 or the air outlet 22.
[0020] Specific work flow: the electric energy meter box works normally, collects and measures the energy consumption of the surrounding electric energy equipment, and remotely transmits it to the data center; during the above normal working process, due to the characteristics of high humidity and high temperature in the hot and humid environment in summer, the heat released during the operation of the electric energy metering module 3 and other electrical components inside the electric energy meter box accumulates inside the box body 1. The nearly closed environment inside the box body 1 makes it difficult for the accumulated heat to be transferred to the outside world, resulting in the internal temperature of the box body 1 being too high, affecting the normal operation of the electric energy metering module 3 and other electrical components, and even increasing the probability of overheating and combustion accidents inside the electric energy meter box; cooling technical means commonly adopted in the existing market, such as setting a cooling fan 12 and other structures, need to maintain direct airflow exchange between the box body 1 and the external environment, which can easily cause the water vapor in the air brought in from the external hot and humid environment to threaten the normal operation of the electrical components inside the box body 1 in a humid environment; Therefore, the present application provides a protective component 2 to ensure air exchange between the inside and outside areas of the box 1, thereby improving the heat dissipation efficiency and effectively preventing external water vapor and impurities from penetrating into the box 1 and threatening the normal operation of the electrical components inside the box 1. Specifically, during the period other than manual inspection or meter reading, the closed door 11 at the opening of the box 1 is kept closed. After the closed door 11 is in close contact with the sealing strip on the protective plate 21, the direct exchange of air between the inside and outside of the box 1 is effectively prevented, so that the inside of the box 1 is in a nearly closed and safe environment. A temperature and humidity sensor is arranged inside the box 1 to monitor the working environment inside the box 1 in real time. When it is detected that the temperature inside the box 1 is too high, the cooling fan 12 is started to introduce the hot air inside the box 1 into the outside, so that the inside of the box 1 is in a negative pressure environment. In this way, under the action of the air pressure difference, the outside air is prompted to flow in from the gap between the closed door 11 and the opening of the box 1. After being intercepted by the closing strip 22, the inflowing air can only flow in from the air inlet 221 set on the surface of the closing strip 22, pass through the gap between the dry particles in the hollow area inside the closing strip 22, and flow into the inside of the box 1 along the air outlet 222, so as to achieve The continuous outward flow of air inside the box 1 promotes air exchange between the inside and outside areas of the box 1, accelerates the removal of heat generated during the operation of the electrical components inside the box 1, and improves the cooling efficiency; and in the process of the air flow passing through the inside of the sealing strip 22, it fully contacts the dry particles inside the sealing strip 22, thereby prompting the water vapor in the air flow to be fully absorbed by the dry particles, reducing the humidity of the incoming air flow, so that the dried cooling air flow is replenished into the inside of the box 1, fully cooling the electrical components inside the box 1 while avoiding the incoming air flow from bringing in too much water vapor to threaten the safe operation of electrical structures such as smart meters.
[0021] Example 2: On the basis of the first embodiment, a limiting groove 211 is provided on the surface of the protective plate 21 at a position corresponding to the closing strip 22. The closing 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. The air guide hole 212 connects the limiting groove 211 with the interior of the box body 1. The closing strip 22 protrudes from the surface of the protective plate 21 near the closed door 11. In this way, when the closed door 11 is closed, it can closely contact the inner wall of the closed door 11, intercepting the inflowing airflow and allowing it to flow only along the air inlet hole 221. The extension track of the limiting groove 211 is square, and a driving groove 213 is provided on the inner wall of the limiting groove 211 near the right-angle turning position. A driving roller 23 is provided on the inner wall of the driving groove 213. The driving roller 23 contacts the surface of the closing strip 22, and the driving roller 23 is controlled by a rotating device in the inner wall of the driving groove 213. The rotating device can be a micro driving motor device, and the output end is connected to the driving roller 23, which can drive the closing strip 22 to rotate along the extension track of the limiting groove 211; impact blocks 231 are evenly provided on the outer surface of the driving roller 23, and the end of the impact block 231 is tapered and contacts the surface of the closing strip 22; the closing strip 22 is in a relaxed state in the driving groove 213 and is not restricted. In this way, when the closing strip 22 slides to the turning position and deforms at a right angle, 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 closing strip 22.
[0022] Specific working process: Based on the specific working process in Example 1, in order to ensure the uniform distribution of the humidity of the dry particles inside the closing strip 22, reduce the problem of the dry particles in local areas absorbing too much water vapor and becoming ineffective, or even causing agglomeration due to excessive humidity, which affects the uneven flow of air; the present application sets the closing strip 22 to be slidably embedded in the limiting groove 211 provided on the surface of the protective plate 21, and after working for a period of time, the rotating device located in the inner wall of the driving groove 213 is started at a regular time, so that the output end of the rotating device drives the driving roller 23 to rotate, thereby driving the closing strip 22 to slide along the annular limiting groove 211; during the sliding process, the external vibration and the inertia of the internal dry particles cause the dry particles located inside the closing strip 22 to move relative to the closing strip 22 during the movement of the closing strip 22, thereby accelerating the exchange and flow of dry particles at different positions inside the closing strip 22; In particular, when the various parts of the sealing strip 22 successively pass through the driving roller 23 at the right-angle turning position, the severe bending deformation of the sealing strip 22 and the squeezing and impact of the conical impact block 231 on the driving 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, this accelerates the flow of the dry particles in the hollow area inside the sealing strip 22. 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 the high humidity, to disperse due to the impact, so that the dry particles in the area inside the sealing strip 22 remain loose and dispersed, thereby ensuring the passability of the area inside the sealing strip 22. In addition, because the extension trajectory of the limiting groove 211 is square, when the horizontal part of the sealing strip 22 rotates to a vertical position, 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, ensuring 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.
[0023] Example 3: Based on the second embodiment, the cross section of the closing strip 22 is elliptical, and the spacing between the openings of the limiting grooves 211 is smaller than the maximum diameter of the cross section of the closing strip 22, so that the closing strip 22 is confined inside the limiting grooves 211; Specific working process: On the basis of the specific working process in Example 2, in order to prevent the closing strip 22 from rotating relatively greatly inside the limiting groove 211, deforming and twisting, and increasing the friction between the closing strip 22 and the inner wall of the limiting groove 211, thereby affecting the sliding of the closing strip 22 along the limiting groove 211; the closing strip 22 is set to have an elliptical flat structure in cross section, and the limiting groove 211 is also approximately elliptical in cross section, and the opening of the limiting groove 211 is smaller, smaller than the maximum diameter of the closing strip 22 cross section, so that when the closing strip 22 slides along the inner wall of the limiting groove 211, the closing strip 22 is prevented from being separated from the limiting groove 211 due to deformation; similarly, the mutual engagement of the elliptical closing strip 22 and the limiting groove 211 also prevents the closing strip 22 from rotating around the extension trajectory of the limiting groove 211 during the sliding process along the limiting groove 211, thereby ensuring the smooth sliding of the closing strip 22 along the limiting groove 211; Furthermore, in order to make the closing strip 22 slide more smoothly along the limiting groove 211, the part of the closing strip 22 close to the closing door 11 can be made of elastic material, and the other parts can be made of elastic metal hose material with a smooth surface, and lubricating oil can be applied to the inner wall of the limiting groove 211 to improve the sealing of the gap part and make the sliding of the closing strip 22 smoother.
[0024] Example 4: Based on the third embodiment, the cooling fan 12 includes an air intake fan 121 and an air outlet fan 122. The air guide holes 212 are concentrated in the areas near the bottom and top of the protective plate 21, and the ventilation slots 111 are also distributed in the areas near the top and bottom of the closed door 11. The air intake fan 121 is arranged at the bottom of the box body 1, and the air intake end of the air intake fan 121 is connected to the air guide holes 212 near the bottom of the protective plate 21; the air outlet fan 122 is arranged at the top of the box body 1, and the air outlet end of the air outlet fan 122 is connected to the air guide holes 212 in the top area of the protective plate 21. Specific working process: On the basis of the specific working process in Example 3, the bottom area and the top area where the air guide holes 212 on the inner wall of the upper limit groove 211 of the protective plate 21 are concentrated are respectively the air inlet area and the air outlet area; for the closing strip 22 part in the air inlet area, due to the action of the air inlet fan 121 inside the box body 1, a negative pressure occurs in the air guide holes 212 connected to the air inlet end of the air inlet fan 121, which will accelerate the flow of external air into the interior of the closing strip 22 part corresponding to the air inlet area, and after being dried by the drying particles, it is sucked in by the air inlet end of the air inlet fan 121, and then flows into the interior of the box body 1 from the air outlet end of the air inlet fan 121, and flushes from bottom to top inside the box body 1, taking away the heat generated by the electrical components inside the box body 1 and the water vapor that may penetrate and flow in; After the hot air flows into the top of the box body 1, it is sucked in by the exhaust action of the air outlet fan 122, and then flows out from the air outlet end of the air outlet fan 122 into the air guide hole 212 corresponding to the air outlet area, and then flows into the inside of the sealing strip 22 of the air outlet area, passes through the gap between the drying particles, and then flows to the outside through the air inlet hole 221; the process of the dry hot air flow passing through the sealing strip 22 of the air outlet area can flush and dry the sealing strip 22 inside the air outlet area, so that the water vapor adsorbed by the drying particles inside the sealing strip 22 of the air outlet area evaporates under the heating action of the hot air flow, and flows to the outside with the air flow, thereby realizing the restoration of the water absorption and drying effect of the drying particles in the area inside the sealing strip 22 of the air outlet area; The air inlet and outlet areas are separated by the vertical sealing strips 22 and the driving rollers 23 at the corners that are in close contact and squeeze each other, making it difficult for the inflow and outflow to interfere with each other inside the sealing strips 22, thus ensuring that the working processes of the air inlet and outlet areas can proceed normally. Therefore, by starting the rotating equipment at a fixed time, the air intake area and the sealing strip 22 part that absorbs more water vapor are transferred to the air outlet area, and the sealing strip 22 in the air outlet area that keeps the internal dry particles in a dry and dispersed state is transferred to the air outlet area, so that the dry particles absorb the water vapor of the incoming air flow and are carried away by the outgoing air flow, thereby improving 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 water vapor and cannot work normally.
[0025] Embodiment 5: On the basis of the fourth embodiment, an annular air duct 24 is provided in the middle position inside the closing strip 22, and the dry particles are distributed in the gap area between the air duct 24 and the inner wall of the closing strip 22. An air outlet pipe 241 is provided at a position on the side wall of the air duct 24 corresponding to the air outlet hole 222. The air outlet pipe 241 connects the air outlet hole 222 and the interior of the air duct 24, and through holes are evenly provided on the side wall of the air duct 24. The aperture of the through holes is smaller than the particle size of the dry particles.
[0026] Specific workflow: Based on the specific workflow in Example 4, in order to improve the efficiency of airflow passing through the interior of the sealing strip 22, an air guide tube 24 is provided inside the sealing strip 22. The cross-sectional area of the air guide tube 24 is less than half the cross-sectional area of the hollow area inside the sealing strip 22, and the dry particles are evenly distributed in the gap area between the air guide tube 24 and the inner wall of the sealing strip 22. In this way, in the air inlet area, the negative pressure of the air guide holes 212 is directly transmitted to the interior of the air guide tube 24, so that the airflow from the outside into the gap between the dry particles, after contacting the dry particles and undergoing water absorption and drying, can quickly pass through the through holes provided in the side wall of the air guide tube 24, flow along the air outlet pipe 241 on the side wall of the air guide tube 24, and then flow into the interior of the box 1, thereby improving the efficiency of the airflow passing through the gap between the dry particles to participate in the air cooling process inside the box 1. Furthermore, in the air outlet area, after passing through the air guide holes 212 and the air outlet pipe 241, the outflowing hot air flow directly flows into the gap between the dry particles in the sealing strip 22 corresponding to the air outlet area. The air guide pipe 24 makes the dry hot air flow more evenly distributed. After flowing out, the dry hot air flow fully contacts 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 air flow. In this way, these dry particles can normally play the role of purifying and drying the incoming air flow when they subsequently move to the air inlet area, thereby improving the continuous working characteristics of the sealing strip 22. Furthermore, when the closing strip 22 slides along the inside of the limiting groove 211, due to the difference in speed and deformation amplitude between the air guide tube 24 and the closing strip 22 during movement, the dry particles filled in the gap area are subjected to extrusion impact, which promotes the fluidity of the dry particles and further prevents the tendency of the dry particles to aggregate into clusters.
[0027] Example 6: On the basis of Example 5, the protective plate 21 is elastically connected to the inner wall of the opening of the box body 1. There are many possible implementation schemes for the specific method of the elastic connection. All implementation schemes that can achieve relative vibration between the protective plate 21 and the opening of the box body 1 are applicable to the present application. For example, the outer edge of the protective plate 21 with a square ring structure and the inner wall of the opening of the box body 1 can be made of elastic material, or a limiting rod on the end of the edge of the protective plate 21 is slidably embedded in a limiting hole provided on the inner wall of the opening of the box body 1, and a spring is provided between the limiting rod and the limiting hole, so that when the vibration device is started, the limiting rod drives the protective plate 21 along the limiting hole to perform a small-amplitude high-frequency vibration in the horizontal direction; and a vibration device is provided inside the protective plate 21, and the vibration device can specifically be a micro vibration motor, etc., and the vibration device is controlled by an external controller; Specific work flow: Based on the specific work flow in Example 5, when the cooling fan 12 is started, the vibration device can be started at a fixed time to drive the protective plate 21 to vibrate elastically. Because the surface of the closing strip 22 maintains close contact with the inner wall of the closed door 11, the elastic vibration causes the contact part of the closing strip 22 on the protective plate 21 to move with a high frequency and a small amplitude with the closed door 11, so that the closing strip 22 is subjected to vibration extrusion, and the size of the hollow area inside the closing strip 2 continuously changes, prompting the air in the internal dry particle gaps to accelerate the flow and impact along the dry particle gaps during the vibration extrusion process, thereby improving the air exchange between the internal and external areas, and while increasing the contact degree between the dry particles and the incoming airflow, promoting the fluidity of the dry particles.
[0028] Embodiment seven: Based on the sixth embodiment, the gap between the air guide tube 24 and the inner wall of the sealing strip 22 is further 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; Specific workflow: Based on the specific workflow in Example 6, as the closing strip 2 rotates along the inside of the limiting groove 211, the vibrator is started at the same time to cause the closing strip 2 to vibrate. During this process, the metal particles and the dry particles contact and impact each other, and the rough surface of the metal particles scrapes the surface of the dry particles, removing 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 set to a metal conductive material and grounded. In this way, when the dry particles adsorb dust flowing into the air flow due to the electrostatic characteristics, they move to the air outlet area and are affected by the conductive characteristics of the metal particles and the air outlet area of the protective plate 21, so that the static electricity is discharged, reducing the adsorption effect of the dry particles on dust and impurities, and allowing the cleaned dust and impurities to be removed by the flushing action of the outflowing air flow, thereby improving the cleaning effect of the dry particles.
