Description

Technical Field

[0001] This invention belongs to the field of metering box technology, specifically a multifunctional electricity metering box. Background Technology

[0002] Metering boxes come in various types, including indoor and outdoor models. Outdoor metering boxes are installed outdoors (such as by the roadside, in green belts of residential areas, or next to utility poles) and are specialized devices used for metering, monitoring, and managing users' electricity consumption. They must withstand the complex environmental effects of wind, rain, high and low temperatures, ultraviolet radiation, and dust over long periods. Their core function is to accurately measure users' electricity consumption and ensure electrical safety through internal components such as meters, current transformers, and circuit breakers. Outdoor metering boxes include a housing, internal core components, and auxiliary devices.

[0003] Heat dissipation is one of the most common hidden dangers in the long-term operation of outdoor metering boxes. The core issue is the inability to dissipate heat in a timely manner. However, the heat sources of outdoor metering boxes include both internal component heating and external environmental heat transfer. When the internal components are heated, the meter, transformer, and other components operate, and the current flowing through the wires and resistors generates heat. Especially in high-current scenarios, the heat generation increases with the square of the current. In addition, under direct sunlight in summer, the surface temperature of the box can reach 60-70℃. Heat is conducted to the interior through the box, making the internal temperature 15-25℃ higher than the ambient temperature, damaging internal components, shortening the service life, and increasing the frequency of maintenance. Furthermore, the heat dissipation and dust problems of outdoor metering boxes are interconnected and mutually exacerbate each other. Dust accumulation hinders heat dissipation, while high-temperature environments accelerate the chemical reactions of corrosive components in the dust. Both factors together lead to decreased metering accuracy, shortened equipment life, and increased safety risks. Summary of the Invention

[0018] 1.

Under the condition of constant air flow, the air velocity is increased by reducing the flow space, so that the air is accelerated and blows over the heat dissipation fins around the heat-generating large appliances, thereby accelerating the cooling speed of the heat dissipation fins and improving the cooling effect of the heat dissipation fins, thereby improving the heat dissipation effect of the metering box.

Detailed Implementation

[0031] 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.

[0032] Example 1:

[0033] To effectively solve the above problems, see the attached diagram in the instruction manual. Figures 1-9 As shown, it includes a housing 1, a metering unit, a monitoring unit, a protection unit, and an anti-theft unit; it also includes:

[0034] Mounting plate 11 is located near the bottom of box 1. Fan 12 is provided at the bottom of mounting plate 11. Mounting plate 11 and the bottom of box 1 form a sealed space. Coolant is stored at the bottom of box 1. Suction pipes 13 are evenly arranged on both sides of box 1. One end of suction pipe 13 is connected to the outside and the other end is inserted into coolant. Exhaust fan 14 is installed in suction pipe 13. Air outlets 15 are evenly opened on the top of box 1. A canopy 16 is installed above the air outlets 15. Heat dissipation grooves 17 are evenly opened on both sides of box 1. The heat dissipation grooves 17 are inclined towards the canopy 16. Air pump 18 is provided in the canopy 16. Lifting plate 19 is provided at the bottom of canopy 16. Lifting plate 19 is connected to canopy 16 through lifting device 2. A nozzle 21 connected to air pump 18 and corresponding to air outlet 15 is provided at the bottom of lifting plate 19.

[0035] Electrical board 22 is installed above mounting plate 11. Electrical board 22 is close to the middle of both sides of the housing 1. Electrical appliances inside the housing 1 are installed on electrical board 22. Heat sinks 23 are evenly arranged on the side of electrical board 22 away from electrical appliances and are vertically arranged. Temperature sensors are evenly arranged on electrical board 22. Water bags 24 are provided on the side wall of housing 1. The two ends of water bags 24 are close to the heat dissipation grooves 17 on both sides of housing 1. Water bags 24 are vertically arranged. Water pump 25 is provided at the bottom of housing 1. One end of water pump 25 is connected to coolant and the other end is connected to water bag 24. Nozzles 26 are provided on water bag 24 near heat sink 23.

[0036] Fan 12 is a conventional type used for installation in metering boxes, and water is used as the coolant; Lifter 2 is a conventional lifting device; Air pump 18 is used to store air and spray it out instantaneously through nozzle 21, and the air is blown in the opposite direction toward the electrical appliances; Water bag 24 is inflated and restored by water pump 25 filling and pumping water.

[0037] Specific workflow: When the metering box needs heat dissipation, fan 12 and exhaust fan 14 are turned on. Exhaust fan 14 uses suction pipe 13 to draw outside air into the bottom of the coolant. The air is cleaned by the coolant and bubbled out, removing air cleanliness from the metering box, reducing the amount of foreign impurities entering, and improving the cleanliness inside the metering box. Fan 12 blows the purified air from the bottom to the top of the box 1 and exhausts it through the air outlet 15. The blowing of fan 12 unifies the air flow path inside the box 1, increases the air velocity inside the box 1, and achieves the effect of air flushing the electrical appliances, washing away impurities attached to the electrical appliances and improving the cleanliness of the electrical appliances. Since the heat dissipation trough 17 is inclined towards the ceiling 16, when the air blown by fan 12 passes through, the air collides with the inner wall of the heat dissipation trough 17, making it difficult for the air blown by fan 12 to flow out of the heat dissipation trough 17, thus avoiding a reduction in airflow.

[0038] The electrical appliances in the metering box are categorized into those with low heat generation and those with high heat generation. Appliances with high heat generation are prone to heat accumulation in the metering box, affecting the operation of other appliances. Therefore, in the event of high temperatures in summer, the metering box detects high-temperature areas on the electrical board 22 using a temperature sensor. The water pump 25 is activated to pump coolant into the corresponding high-temperature area's water bladder 24. The water bladder 24 begins to inflate until it reaches its maximum expansion. Then, the coolant inside the water bladder 24 is sprayed out through the nozzle 26. The nozzle 26 sprays a mist of coolant onto the heat sink 23. The water mist sprayed from the nozzle 26 consists of a large number of tiny water droplets. Compared to large water droplets, these droplets have a larger surface area and a wider contact area with the air inside the box 1, resulting in faster evaporation. This allows the metering box to absorb heat from the surrounding environment in a short time. By detecting these droplets, the heat dissipation capacity of individual appliances is improved, thereby enhancing the overall heat dissipation effect of the metering box.

[0039] Furthermore, after the water bladder 24 expands, it reduces the space between the heat sink 23 and the inner wall of the housing 1, thus increasing the air velocity by reducing the flow space while maintaining the same airflow. This causes the air to accelerate and blow over the heat sink 23 around the large heat-generating appliance, accelerating the cooling speed of the heat sink 23 and improving its cooling effect, thereby enhancing the heat dissipation of the metering box. In addition, some of the water mist sprayed from the nozzle 26 adheres to the heat sink 23. As the air accelerates and passes over the water mist-containing heat sink 23, the combined effect of wind and water mist evaporation further enhances the heat dissipation effect of the heat sink 23 on the appliance. Furthermore, another part of the water mist sprayed from the nozzle 26 evaporates during its drift. This evaporation absorbs heat, lowering the temperature of the air blowing over the large heat sink 23. Combined with the increased wind speed and the evaporation of water mist on the heat sink 23, these multiple effects further enhance the heat dissipation capacity of the heat sink 23, thereby improving the heat dissipation effect of the metering box.

[0040] At night, the ambient air temperature around the metering box is low, allowing for direct cooling by drawing in outside air. Fan 12 and exhaust fan 14 rotate slowly to prevent reverse airflow into the coolant, thus avoiding coolant backflow to the outside. The lifting device 2 activates, causing the lifting plate 19 to descend from above the air outlet 15 to the point where it connects to the outlet. Then, the air pump 18 blows the stored air into the box 1. At this time, the air inside the box 1 blows downwards, using the reverse airflow to flush away impurities that have accumulated on the electrical components over time, improving the cleanliness of the components and thus enhancing the safety of the metering box. During the reverse air blowing process, the slow rotation of the fan 12 and the exhaust fan 14 prevents reverse air from entering. After passing through the electrical appliances, the reverse-blown air exits through the heat dissipation slots 17 on both sides of the housing 1. After the reverse blowing has been going on for a period of time, the air pump 18 stops, the lifter 2 drives the lifting plate 19 to rise, the air outlet 15 connects to the outside, the exhaust fan 14 and the fan 12 start, and the airflow direction inside the housing 1 changes back to blowing from bottom to top. Through multiple forward and reverse blowing, the removal of impurities on the electrical appliances is further improved, the cleanliness of the electrical appliances is improved, and thus the safety of the metering box is improved.

[0041] Furthermore, if the ambient temperature is too high, the inside of the enclosure 1 may accumulate heat due to sunlight. The roof 16 covers the air outlet 15 and the heat dissipation trough 17, reducing direct sunlight on the enclosure 1. The gap between the roof 16 and the enclosure 1 forms a chimney effect, accelerating the upward flow and discharge of hot air. To prevent dust from entering the enclosure 1 through the heat dissipation trough 17, a filter screen can be installed in the heat dissipation trough 17 during installation to filter dust.

[0042] Example 2:

[0043] Based on Embodiment 1, the cabinet door of the housing 1 is provided with a combination plate 27. A slide rod 28 is slidably connected to the combination plate 27. The end of the slide rod 28 away from the electrical appliance is connected to an electric push rod 29 installed on the combination plate 27, and the end closer to the electrical appliance is provided with a sliding plate 3 through the combination plate 27. Sealing films 31 are connected between the four edges of the sliding plate 3 and the combination plate 27. A first locking block 32 is slidably connected to the combination plate 27 by a spring. A first pull rope 33 is provided on the top of the first locking block 32. One end of the first pull rope 33 is connected to the sliding plate 3. A second locking block 34 is slidably connected to the mounting plate 11 by a spring. The bottom of the first locking block 32 and the top of the second locking block 34 match. The bottom of block 34 is provided with a second pull rope 35, and a support frame 36 is provided below the mounting plate 11. A rotating rod 37 is rotatably connected to the support frame 36 through a torsion spring. A sleeve 38 is rotatably connected to the top of the rotating rod 37. A torsion spring is provided between the sleeve 38 and the support frame 36. A linkage block 39 is hinged to the inner wall of the sleeve 38 through the torsion spring. The linkage block 39 is engaged with the outer peripheral surface of the rotating rod 37. One end of the second pull rope 35 is wrapped around the outer peripheral surface of the sleeve 38. The rotating rod 37 is provided with a blade 4 and is submerged in the coolant. An arc-shaped cylinder 41 is provided on the support frame 36 away from the center. When maintenance and meter reading are required, the combination plate 27 can be removed by turning the bolts, and the first locking block 32 and the second locking block 34 slide apart.

[0044] The cylinder 41 and the inner wall of the corner of the box 1 form a storage space, and the storage space contains chemical reagents. The suction pipe 13 is provided with a branch pipe 42, and one end of the branch pipe 42 is located at the bottom of the storage space.

[0045] A collection frame 43 is provided on the inner wall of the cylinder 41, and a collection bag 44 is provided on one side of the collection frame 43;

[0046] The bottom of the collection frame 43 is provided with a partition 45, and the partition 45 is located inside the collection bag 44;

[0047] Specific workflow: During long-term use, meter readers often open the cabinet door to read meters or maintain electrical appliances to avoid risks such as power outages. However, frequent opening of the cabinet door exposes the inside of the meter box to the outside environment for extended periods. The outdoor environment of the meter box itself contains a lot of dust and other impurities, which can easily cause dust to adhere to the electrical appliances. Moreover, static electricity generated by friction and induction when the electrical appliances are powered on can attract dust through charge attraction or polarization, exacerbating the dust contamination of the electrical appliances. Therefore, after the door is opened and closed, the meter box controls the coordination between the fan 12 and the air pump 18 to achieve multiple forward and reverse air blowing inside the meter box. The electric push rod 29 drives the slide plate 3 to move closer to the electrical appliances via the slide rod 28. As the slide plate 3 approaches the electrical appliance plate 22, the space through which the air flows to the electrical appliances gradually shrinks, and the airflow speed gradually increases, increasing the force of air washing over the electrical appliances and improving the dust removal effect, thereby improving the cleanliness of the electrical appliances.

[0048] Furthermore, during the movement of the slide plate 3, one end of the film is tightly attached to the inner wall of the cabinet 1, while the other end connects to the perimeter of the slide plate 3. This ensures that the cooperation between the slide plate 3 and the film achieves the sealing effect of the combination plate 27, improving the sealing performance of the cabinet door and preventing excessive gaps between the cabinet door and the cabinet 1. This would not only affect airflow but also allow dust to easily enter the cabinet 1, thereby improving the heat dissipation and dust prevention effects of the cabinet 1. When the slide plate 3 approaches the electrical panel 22 and then moves away, the airflow space suddenly expands, causing the airflow velocity to decrease. The reciprocating movement of the slide plate 3 causes the airflow velocity to fluctuate. When air flows over the heat sink 23 and the surface of the electrical appliance at a constant flow rate, a layer of air with a high temperature and slow flow rate will be formed on the surface, which will hinder heat transfer. Frequent changes in flow rate will impact and tear the thermal boundary layer, allowing the low temperature air to directly contact the high temperature surface, thereby improving the heat exchange efficiency and heat dissipation effect. It can also avoid local heat retention. For electrical appliances with complex structures, such as the gaps in the current transformer coil and the internal components of the meter, dynamic airflow can penetrate narrow spaces through changes in flow rate and carry away the retained hot air, because these areas are prone to forming high temperature dead zones under static airflow.

[0049] Furthermore, when dust adheres to the surface of electrical appliances or the gaps in the heat sink 23, static airflow has difficulty overcoming the adhesion between the dust and the surface, especially the micro-dust adsorbed by electrostatics. Frequent changes in airflow velocity will generate alternating impact forces. At low airflow velocity, the airflow seeps into the gaps and loosens the dust; at high airflow velocity, the strong impact force will peel the loosened dust off the surface, similar to the effect of loosening and then blowing, which improves the dust removal effect and thus improves the cleanliness of the electrical appliances. The turbulence generated by the change in airflow velocity can impact the surface at different angles, avoiding the situation where directional static airflow is insufficient in cleaning certain dead corners.

[0050] In addition, the varying airflow speed ensures that the water mist is evenly distributed on the surface of the heat sink 23. High-speed airflow disperses the accumulated water mist, while low-speed airflow fully wets the heat sink 23, enhancing the cooling effect of water mist evaporation and thus improving the heat dissipation performance of the heat sink 23. Under the action of dynamic airflow, the vertically arranged heat sink 23 allows airflow to alternately pass through the fin gaps from different angles, avoiding the problem of one side being fully cooled while the other side accumulates heat due to airflow from a single direction, thereby improving the overall temperature uniformity of the heat sink 23. The temperature sensor triggers airflow speed variation, such as increasing the frequency of airflow speed variation at high temperatures, to achieve intelligent adaptation, ensuring heat dissipation requirements while extending the life of the fan 12 through intermittent low-speed operation. The frequent changes in airflow speed inside the metering box enhance heat exchange, dynamically remove dust, and work in conjunction with other structures, thereby improving heat dissipation efficiency, avoiding localized high temperatures, and enhancing dust removal, making it particularly suitable for the complex heat dissipation and dusty environments of outdoor metering boxes.

[0051] During the installation of the combination plate 27, the bottom of the first locking block 32 and the top of the second locking block 34 are inserted and connected to each other. When the slide plate 3 is close to the electrical appliance, the first locking block 32 is lifted by the first pull rope 33. The first locking block 32 drives the second locking block 34 to rise and enter the combination plate 27. The second locking block 34 drives the sleeve 38 to rotate through the second pull rope 35. The sleeve 38 drives the unidirectional swing linkage block 39 to rotate in the forward direction. At this time, the linkage block 39 is engaged with the rotating rod 37, and the linkage block 39 is affected by the unidirectional swing, so that the sleeve 38 can drive the rotating rod 37 to rotate in the forward direction. When the slide plate 3 is away from the electrical appliance, the first locking block 32 and the second locking block 34 descend and reset, and the second pull rope 35 no longer pulls. Sleeve 38 is rotated in the opposite direction to reset due to the torsion spring on support frame 36. At this time, linkage block 39 can swing away from rotating rod 37. Rotating rod 37 continues to rotate in the forward direction due to the inertia of motion. Sleeve 38 drives linkage block 39 to rotate in the opposite direction until slide plate 3 approaches the electrical appliance again, causing sleeve 38 to continue to drive rotating rod 37 to rotate in the forward direction. Rotating rod 37 drives coolant to rotate through blade 4. The coolant rotates in cylinder 41 and generates centrifugal force to throw internal impurities onto the inner wall of cylinder 41, cleaning the coolant and preventing the air entering the box 1 from being contaminated by impurities, thus improving the cleanliness of the air and reducing the degree of contamination of electrical appliances, thereby improving the dust removal effect in metering box.

[0052] In addition, during installation, the sleeve 38 and linkage block 39 can be replaced with a motor. The motor drives the rotating rod 37 to rotate. The rotation speed of the motor depends on the number of times the second pull rope 35 is pulled. The second pull rope 35 rotates once for every pull. The more times it is pulled, the more frequently the slide plate 3 moves and the more frequently the air flows in both directions, which requires more dust removal and heat dissipation. Moreover, when the coolant is rotating, the end of the suction pipe 13 near the bottom of the rotating rod 37 sprays out air. The air is affected by centrifugal force and moves away from the rotating rod 37 while floating upward. Compared with direct floating, the time for the air to contact the coolant is extended, which fully reduces the air temperature and removes impurities from the air by water washing, improving the heat dissipation effect of the electrical components, thereby improving the heat dissipation effect of the metering box.

[0053] The chemical reagent used is ammonium nitrate. When dissolved in water, the heat absorbed during the diffusion process is greater than the heat released during the hydration process, resulting in an endothermic reaction, which is characteristic of endothermic dissolution. When air is sprayed into the coolant through the suction pipe 13, the air flows rapidly through the branch pipe 42. The high-speed airflow causes a local pressure drop in the suction pipe 13, creating a negative pressure. This draws the chemical reagent from the branch pipe 42 into the suction pipe 13, where it enters the coolant along with the air. Contact with the coolant lowers its temperature, thereby reducing the air temperature and improving the heat dissipation of the metering chamber. Furthermore, the chemical reagent in the coolant is also affected by centrifugation, moving from the center of the cylinder 41 to the sidewall. During this movement, the chemical reagent continuously contacts new coolant, maintaining a continuous reaction while ensuring that the coolant in the cylinder 41 is reacted from the center to the sidewall. Combined with the rotation, this evenly lowers the coolant temperature, preventing some air from being insufficiently cooled.

[0054] By setting up a collection bag 44, during the rotation of the coolant, impurities are moved along the side wall of the cylinder 41 until they pass through the collection frame 43 and enter the collection bag 44, completing the impurity collection work. This prevents impurities from being carried away from the coolant and flowing with the air during the bubbling process, thereby improving the cleanliness of the coolant and consequently the cleanliness of the air. Furthermore, when the coolant is stationary, the collection bag 44 is also in a downward state. When the collection bag 44 is in this downward state, the partition 45 is horizontally placed at the opening of the collection bag 44, sealing the opening and preventing impurities accumulated at the bottom of the collection bag 44 from flowing out. After the coolant rotates for a period of time, it causes the downward-sloping collection bag 44 to become horizontal, and the opening of the collection bag 44 opens away from the partition 45, allowing impurities to enter the collection bag 44. This prevents impurities from flowing out and contaminating the coolant, thereby improving the purification level of the coolant.

[0055] Example 3:

[0056] Based on Embodiment 2, the top of the cylinder 41 is provided with a sealing cover 46, and the top of the sealing cover 46 is slidably connected to a rack 47 by a spring. The rotating rod 37 is provided with a drive rod 48 to move the rack 47; the end of the drive rod 48 that contacts the rack 47 is made of rubber.

[0057] The top of the sealing cover 46 is rotatably connected to a spiral shaft 49, the top of the spiral shaft 49 meshes with a rack 47, and the bottom of the spiral shaft 49 is close to the branch pipe 42; the spiral shaft 49 is a conventional part such as an auger, and the top of the spiral shaft 49 is provided with a gear to mesh with the rack 47;

[0058] Specific workflow: Rotating rod 37 drives driving rod 48 to rotate. Driving rod 48 moves rack 47 from one side of sealing cover 46 to the other side until rack 47 moves to its limit position. Since the end of driving rod 48 that contacts rack 47 is made of rubber, driving rod 48 and rack 47 squeeze the rubber part until it deforms. Driving rod 48 passes rack 47, rack 47 slides back to reset through spring and generates impact vibration, which causes cylinder 41 to vibrate. The frequent vibration of cylinder 41 disperses the impurities attached to the side wall and flows with the coolant, improving the impurity removal efficiency. At the same time, the vibration of cylinder 41 drives the chemical reagent to vibrate. Through frequent vibration, the agglomerates formed in the chemical reagent due to oxidation and other conditions are dispersed, making it easier to be sucked by branch pipe 42, maintaining a fixed amount of chemical reagent added, thereby improving the cooling effect of coolant on air.

[0059] The reciprocating movement of the rack 47 drives the spiral shaft 49 to rotate in both directions through meshing. The spiral shaft 49 agitates and breaks up the chemical reagents at the port of the branch pipe 42, making it easier for the chemical reagents to enter the branch pipe 42 and preventing the chemical reagents from clogging the port of the branch pipe 42.

[0060] Example 4:

[0061] Based on Embodiment 3, the bottom of the mounting plate 11 is provided with a fixing frame 5, and a dehumidifying net 51 is slidably connected in the middle layer of the fixing frame 5. One end of the dehumidifying net 51 is connected to the second pull rope 35, and the other end is connected to one end of the fixing frame 5 through a spring.

[0062] The fixed frame 5 has a groove 52, and a rotating shaft 53 is rotatably connected in the groove 52. The top of the rotating shaft 53 contacts the bottom of the dehumidifying mesh 51. The groove 52 stores a water absorbent. The water absorbent can be ammonium nitrate powder, which is the same as the chemical reagent. After the water absorbent comes into contact with the dehumidifying mesh 51, it can absorb the moisture on the dehumidifying mesh 51 and reduce the temperature of the dehumidifying mesh 51, thereby increasing the air cooling method and improving the air cooling effect, thus improving the air cooling effect on the electrical appliances.

[0063] The rotating shaft 53 is evenly provided with spikes 54, and the top of the spikes 54 passes through the dehumidifying mesh 51;

[0064] Specific workflow: When the second pull rope 35 is pulled and moved, it causes the dehumidifying screen 51 to move laterally within the fixed frame 5. The dehumidifying screen 51 is a conventional part used for filtering and drying air. The impurities and moisture filtered on the dehumidifying screen 51 are scraped off by the fixed frame 5 and fall back into the coolant. When the second pull rope 35 is no longer pulled, the spring drives the dehumidifying screen 51 to move and reset. The cleaned part of the dehumidifying screen 51 starts filtering air again, reducing the humidity and impurities in the air, avoiding damage to electrical appliances, and improving the protection of electrical appliances by the metering box.

[0065] When the second pull rope 35 pulls the dehumidifying net 51, the dehumidifying net 51 is squeezed and scraped by the fixed frame 5 and passes through the groove 52. The top of the rotating shaft 53 contacts the bottom of the dehumidifying net 51, causing the dehumidifying net 51 to drive the rotating shaft 53 to rotate. The bottom of the rotating shaft 53 is rotated to contact the bottom of the dehumidifying net 51. The bottom of the rotating shaft 53, with the attached water-absorbing agent, contacts the dehumidifying net 51. The water-absorbing agent absorbs the moisture in the dehumidifying net 51, accelerates the drying speed of the dehumidifying net 51, improves the dehumidifying capacity of the dehumidifying net 51, reduces the moisture content in the air, and avoids damage to electrical appliances.

[0066] By setting spikes 54, it is ensured that the dehumidifying net 51 can drive the rotating shaft 53 to rotate, promoting the contact of the desiccant with the dehumidifying net 51; and when the rotating shaft 53 rotates along the surface of the dehumidifying net 51, the spikes 54 pass through the dehumidifying net 51, clearing the dehumidifying net 51, preventing the dehumidifying net 51 from being blocked by impurities or desiccant, which would affect the airflow, thereby improving the ease of use and thus improving the practicality of the metering box.
