Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to an environmentally friendly and energy-saving intelligent power metering box. Background Technology

[0002] In the field of electrical equipment technology, the development of electricity metering boxes is crucial, as they are one of the key devices ensuring accurate metering and stable operation of power systems. With the continuous development of the power industry, the performance requirements for electricity metering boxes are also increasing. They must not only guarantee metering accuracy but also consider adaptability and reliability in different environments. At the same time, the growing awareness of environmental protection and energy conservation has led to greater emphasis on energy efficiency and environmental protection in the design and use of electricity metering boxes. A high-performance electricity metering box can effectively reduce power loss, improve the operating efficiency of the power system, and bring significant economic benefits to power users and power supply companies.

[0003] In the past, various methods were typically employed to address the heat dissipation and power supply issues of electricity metering boxes. For heat dissipation, a common approach was to create fixed ventilation openings on the box, relying on natural airflow to exchange air and remove heat generated inside. Alternatively, fixed cooling fans were installed inside the box to accelerate airflow and enhance heat dissipation. Regarding power supply, traditional electricity metering boxes primarily relied on mains power to maintain the normal operation of internal equipment. While this power supply method is relatively stable, its limitations are becoming increasingly apparent in remote areas or scenarios with strict energy consumption requirements.

[0004] However, these existing technologies have significant drawbacks. Fixed vents are highly susceptible to environmental factors; in poorly ventilated or high-temperature conditions, their cooling effect is often inadequate, failing to meet the temperature requirements of the equipment inside the enclosure. While fixed-position cooling fans can improve cooling efficiency to some extent, they cannot provide targeted cooling based on temperature variations at different locations within the enclosure, easily leading to localized overheating and affecting the normal operation and lifespan of the equipment. Relying solely on mains power not only increases energy consumption and operating costs but also, in the event of an unstable mains power supply, may affect the normal operation of the electricity metering box. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide an environmentally friendly and energy-saving intelligent power metering box.

[0006] An environmentally friendly and energy-saving intelligent electricity metering box includes a box body. The sides of both sides of the box body are provided with strip-shaped grooves. Several air inlets are provided at the bottom of the grooves. An openable and closable ventilation component is provided inside the grooves. When the ventilation component is turned on, it can communicate with the outside air through the air inlets.

[0007] The enclosure is slidably connected to a heat dissipation component within a strip groove, and a drive component is provided inside the enclosure to drive the heat dissipation component to slide along the strip groove.

[0008] The heat dissipation component is equipped with a trigger. When the heat dissipation component moves to the position corresponding to a certain ventilation component, the trigger can activate the ventilation component at that position.

[0009] The enclosure contains a control unit and multiple temperature sensors, which are used to detect the temperature at different levels within the enclosure.

[0010] Based on the detection signal from the temperature sensor, the control unit controls the drive assembly to move the heat dissipation assembly to the high-temperature area and controls the ventilation assembly to turn on in the corresponding position.

[0011] The enclosure is equipped with a solar power supply system, which includes solar panels, a battery, and a power management module.

[0012] The solar panels and batteries power the drive components, heat dissipation components, control unit, and temperature sensor via a power management module.

[0013] By adopting the above technical solutions, the air inlet and ventilation components work together to connect the enclosure with the outside air, which is conducive to air circulation and heat dissipation. The heat dissipation component can move along the strip groove under the drive component. The control unit, combined with the temperature sensor detection signal, controls the heat dissipation component to move to the high temperature area and activates the ventilation component at the corresponding position to achieve targeted heat dissipation and improve heat dissipation efficiency. The solar power supply component powers the drive component, heat dissipation component, control unit and temperature sensor, achieving environmental protection and energy saving.

[0014] Optionally, the ventilation assembly includes a fixed plate, a ventilation column, and a return spring. The fixed plate is set in a strip-shaped groove and separates the air inlet from the interior of the housing. Several through holes are opened on the fixed plate. The ventilation column is slidably connected in the through holes. A ventilation groove is opened on the ventilation column. A sealing plate is fixedly connected to one end of the ventilation column inside the housing. A sealing ring that abuts against the fixed plate is set on one side of the sealing plate, and a metal block is set on the other side of the sealing plate. The return spring is set in the through holes and is used to provide elastic force to the ventilation column to keep it in a closed tendency. The trigger is a permanent magnet set on the heat dissipation assembly. When the heat dissipation assembly moves to the corresponding position of the ventilation assembly, the magnetic force between the permanent magnet and the metal block can overcome the elastic force of the return spring and drive the ventilation column to slide to the open position.

[0015] By adopting the above technical solution, the fixing plate separates the air inlet from the inside of the box, blocking some dust and reducing the amount of dust entering the box; the return spring keeps the ventilation column in a closed position, preventing external dust and moisture from entering when ventilation is not needed; the magnetic force between the permanent magnet and the metal block can overcome the spring force of the return spring and open the ventilation column when the heat dissipation component moves to the corresponding position, so that the ventilation component can automatically open and close according to the heat dissipation demand, allowing the inside of the box to communicate with the outside air for ventilation and heat dissipation.

[0016] Optionally, the heat dissipation assembly includes a sliding cover slidably connected within a strip-shaped groove, the surface of the sliding cover being connected to the drive assembly and abutting against a fixed plate; a hollow filter rod is inserted through the sliding cover, a filter element is disposed inside the filter rod, and an air inlet is provided on the filter rod; a permanent magnet is disposed at the end of the filter rod inside the sliding cover, and a rotating disk is rotatably connected to the side of the filter rod away from the permanent magnet, and an air outlet frame is disposed on the rotating disk; the air outlet frame is hollow and communicates with the interior of the filter rod, and several air outlet holes are provided on the air outlet frame.

[0017] By adopting the above technical solution, the sliding cover is connected to the drive component and abuts against the fixed plate, and can slide along the strip groove; the filter rod is hollow and is equipped with filter elements and an air inlet, which can filter the incoming air; the permanent magnet is set at the end of the filter rod, which can cooperate with the metal block of the ventilation component to open the ventilation column; the rotating disk makes the filter rod and the air outlet frame rotate and connect; the air outlet frame is hollow and has air outlet holes, which can deliver the filtered air into the box to achieve precise heat dissipation.

[0018] Optionally, several cooling fans are installed on the air outlet frame.

[0019] By adopting the above technical solution and installing several cooling fans on the air outlet frame, the direction of airflow at the air outlet can be controlled, thereby improving the accuracy of heat dissipation.

[0020] Optionally, the enclosure is equipped with a dustproof screen, which is placed over the air inlet.

[0021] By adopting the above technical solution, a dustproof net is installed on the enclosure and covered over the air inlet, which can block some of the dust in the outside air, reduce the amount of dust entering the enclosure through the air inlet, reduce the impact of dust on the electrical components inside the enclosure, and improve the reliability and service life of the equipment.

[0022] Optionally, the top of the enclosure is equipped with a transparent cover, and the solar panels are installed inside the transparent cover.

[0023] By adopting the above technical solution, a transparent cover is set on the top of the box and the solar panel is placed inside. This can protect the solar panel while allowing sunlight to pass through, so that the solar panel can normally convert solar energy into electrical energy.

[0024] Optionally, the top of the enclosure has several ventilation holes inside a transparent cover, and the side of the transparent cover has ventilation slots.

[0025] By adopting the above technical solution, an exhaust hole is opened inside the transparent cover on the top of the box, and an exhaust groove is opened on the side of the transparent cover. This allows the hot air inside the box to flow into the transparent cover through the exhaust hole and then be discharged to the outside through the exhaust groove, thus achieving effective exhaust of the hot air inside the box and facilitating heat dissipation.

[0026] Optionally, the ventilation duct at the top of the enclosure is equipped with a downward-bent waterproof pipe.

[0027] By adopting the above technical solutions, the transparent cover can protect the solar panels; the vent on the top of the enclosure and the vent slot of the transparent cover can expel hot air; and the downward-bent waterproof pipe can prevent rainwater from entering the enclosure, ensuring that the equipment can operate normally in rainy environments.

[0028] Optionally, the power management module can also be connected to AC power. The power management module is configured to prioritize solar power and automatically switch to AC power when the battery charge is below a set threshold.

[0029] By adopting the above technical solutions, the power management module can prioritize solar power supply to achieve environmental protection and energy saving. At the same time, it can automatically switch to mains power supply when the battery power is lower than the set threshold, ensuring the continuous and stable operation of the drive components, heat dissipation components, control units and temperature sensors in the smart power metering box.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Based on the detection signal from the temperature sensor, the control unit controls the drive component to move the heat dissipation component to the high-temperature area and controls the ventilation component to open in the corresponding position. This can provide targeted heat dissipation for the high-temperature area of ​​the cabinet, avoid excessive local temperature, improve the accuracy of heat dissipation, and ensure the normal operation and service life of the equipment.

[0032] 2. The solar panels and batteries of the solar power supply module supply power to the drive components, heat dissipation components, control unit and temperature sensor through the power management module. The power management module prioritizes solar power supply and automatically switches to mains power supply when the battery power is lower than a set threshold. This reduces dependence on mains power, lowers energy consumption and operating costs, and achieves environmental protection and energy saving.

[0033] 3. After the ventilation components are turned on, they can connect with the outside air through the air inlet. Combined with the heat dissipation components, they can dissipate heat and cool down the electrical components inside the cabinet, thus solving the problem of poor heat dissipation effect of fixed ventilation openings due to the influence of the natural environment.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0043] An environmentally friendly and energy-saving intelligent electricity metering box, referring to Figure 1The system includes a housing 1, which houses a heat dissipation assembly 2, a drive assembly 4, a ventilation assembly 3, a control unit 5, a temperature sensor 6, and a solar power supply assembly 7. The ventilation assembly 3 connects the interior of the housing 1 to the outside air; the heat dissipation assembly 2 cools the electrical components inside the housing 1; the control unit 5, temperature sensor 6, and drive assembly 4 work together to move the heat dissipation assembly 2 to the high-temperature area of ​​the housing 1 for targeted heat dissipation; and the solar power supply assembly provides power to the drive assembly 4, heat dissipation assembly 2, control unit 5, and temperature sensor 6.

[0044] Reference Figure 2 , Figure 3 The inner sides of the housing 1 are provided with strip-shaped grooves 8, and the bottom of the grooves 8 has several air inlets 9. A dustproof net 10 is fixedly connected to the surface of the housing 1, and the dustproof net 10 covers the surface of the air inlets 9. The ventilation component 3 includes a fixing plate 301 fixedly connected to the inner wall of the strip-shaped grooves 8, and a gap is provided between the fixing plate 301 and the bottom of the grooves 8, separating the air inlets 9 from the interior of the housing 1. At the same time, the fixing plate 301 has several through holes 11 that are offset from the air inlets 9. When outside air enters through the air inlets 9 after passing through the dustproof net 10, some dust is blocked by the fixing plate 301 and remains in the gap between the fixing plate 301 and the bottom of the grooves 8.

[0045] A guide plate 12 is fixedly connected to the inner wall of the strip groove 8 near the ground. A cleaning port 13 is opened on the side of the box body 1. A cleaning door 14 is rotatably connected to the box body 1 at the cleaning port 13. The dust remaining in the gap between the fixed plate 301 and the bottom of the strip groove 8 is cleaned by opening the cleaning door 14.

[0046] Reference Figure 3 , Figure 4 , Figure 5 A set of return springs 302, corresponding in number to the number of through holes 11, is fixedly connected to the surface of the fixing plate 301 near the bottom of the groove 8. The return springs 302 are conical helical springs. Additionally, a ventilation column 303 is slidably connected within the through hole 11. The ventilation column 303 has a ventilation groove 15, making it U-shaped. The opening of the ventilation groove 15 faces the bottom of the groove 8 and is fixedly connected to the corresponding return spring 302. The other end of the ventilation column 303 engages with the inner wall of the through hole 11 to close it. Simultaneously, the return springs 302 provide elastic force to keep the through hole 11 closed.

[0047] The fixed plate 301 has a number of sealing grooves 16 corresponding to the number of through holes 11 on the side away from the bottom of the groove 8. At the same time, the ventilation column 303 is fixedly connected to a sealing plate 304 at the end away from the reset spring 302, and a sealing ring 305 is fixedly connected to the sealing plate 304. The sealing ring 305 is located in the sealing groove 16 and the surface of the sealing ring 305 is flush with the surface of the fixed plate 301. When the through hole 11 is not open, the sealing ring 305 abuts against the bottom of the sealing groove 16.

[0048] Reference Figure 2 , Figure 4 A metal block 306 is embedded on the side of the sealing plate 304 away from the sealing ring 305. The metal block 306 is used to cooperate with the heat dissipation component 2 to drive the ventilation column 303 to slide into the box 1, and make the bottom of the ventilation groove 15 pass through the fixing plate 301, thereby opening the through hole 11.

[0049] Reference Figure 2 , Figure 6 The drive assembly 4 includes a slide rail 401 fixedly connected to the housing 1, wherein the size of the slide rail 401 matches the strip groove 8. An electric slider 402 is slidably connected within the slide rail 401, and the electric slider 402 is fixedly connected to a drive rod 403. The heat dissipation assembly 2 includes a sliding cover 201 fixedly connected to the drive rod 403, thereby causing the electric slider 402 to drive the sliding cover 201 to slide along the slide rail 401, and the sliding cover 201 to slide synchronously within the strip groove 8. The sliding cover 201 is located within the strip groove 8 and slides along the strip groove 8. Simultaneously, a lubricating bushing 202 is fitted at one end of the sliding cover 201, and the lubricating bushing 202 abuts against the surface of the fixing plate 301, thereby reducing wear at the contact point between the sliding cover 201 and the fixing plate 301.

[0050] Reference Figure 6 , Figure 7 A hollow filter rod 203 is inserted inside the sliding cover 201, and an air inlet 17 is opened on the surface of the filter rod 203. A dehumidifying sponge is filled inside the filter rod 203, and a dustproof cloth 204 is fixedly connected to the air inlet 17.

[0051] Reference Figure 4 , Figure 6 , Figure 7 A permanent magnet 18 is fixedly connected to the side of the filter rod 203 near the fixing plate 301, and the surface of the permanent magnet 18 is coated with epoxy resin to improve the service life of the permanent magnet 18. When the drive assembly 4 controls the sliding cover 201 to slide, the permanent magnet 18 can be magnetically attracted to the metal block 306 of the ventilation column 303 at the corresponding position, so that the corresponding ventilation column 303 overcomes the elastic force of the return spring 302, thereby causing the ventilation column 303 to slide to the position of opening the through hole 11.

[0052] The periphery of the sealing block and the periphery of the lubrication bushing 202 are both rounded. When the sliding cover 201 slides and causes the spring force of the return spring 302 on a certain ventilation column 303 to be greater than the magnetic force of the permanent magnet 18, the periphery of the lubrication bushing 202 comes into contact with the periphery of the sealing block, thereby pressing the ventilation column 303 into the through hole 11 to assist the ventilation column 303 in resetting.

[0053] Reference Figure 6 , Figure 7 A rotating disk 205 is rotatably connected to the end of the filter rod 203 that passes through the sliding cover 201 on the side away from the permanent magnet 18. A positioning ring 206 is fixedly connected to the surface of the rotating disk 205. A positioning screw 19 passes through the positioning ring 206, and a limit pad 20 is fixedly connected to the end of the positioning screw 19. The positioning screw 19 is threadedly connected to the positioning ring 206 to control the magnitude of the contact force between the limit pad 20 and the sliding cover 201, thereby controlling the magnitude of the friction force generated between them.

[0054] Reference Figure 2 , Figure 6 , Figure 7 An air outlet frame 207 is fixedly connected to the side of the rotating disk 205 away from the filter rod 203. The air outlet frame 207 is composed of two air outlet pipes, each of which is connected to the interior of the filter rod 203. Several air outlet holes 21 are opened on the surface of the air outlet pipes, so that the air flowing in from the outside and filtered by the filter rod 203 can flow out from the air outlet holes 21 on the air outlet pipes and enter the interior of the housing 1. Several cooling fans 208 are slidably connected to the air outlet frame 207 to control the direction of the airflow from the air outlet holes 21, thereby improving the accuracy of heat dissipation.

[0055] Reference Figure 1 , Figure 2 The control unit 5 and the temperature sensor 6 are both fixedly connected inside the housing 1. The temperature sensor 6 is signal-connected to the control unit 5, and the control unit 5 is used to receive the signal transmitted by the temperature sensor 6. At the same time, the control unit 5 is signal-connected to the drive component 4.

[0056] Reference Figure 2 , Figure 6 Temperature sensors 6 are fixedly connected to multiple positions at different horizontal heights inside the housing 1 to detect the temperature at different horizontal heights within the housing 1. The control unit 5 receives the detection signals from the temperature sensors 6, compares the readings of each temperature sensor 6, and identifies the highest temperature point. It then controls the drive mechanism to move the cooling fan 208 to the horizontal height corresponding to that highest temperature point. At this time, the ventilation columns 303 within the projection range of the sliding cover 201 open, allowing outside air to flow into the air outlet frame 207, providing support for the operation of the cooling fan 208.

[0057] Reference Figure 2 A transparent cover 22 is fixedly connected to the top of the housing 1. The solar power supply assembly 7 includes a solar panel 701 fixedly connected to the top of the housing 1, and the solar panel 701 is located inside the transparent cover 22. The solar panel 701 is generally a polycrystalline silicon or monocrystalline silicon solar panel, used to convert solar energy into electrical energy. The transparent cover 22 is made of transparent plastic or glass, which protects the solar panel 701 while allowing sunlight to pass through. Several ventilation holes 23 are provided on the top of the housing 1, located below the solar panel 701, and a gap is provided between the solar panel 701 and the top surface of the housing 1. Screws can be inserted through some of the ventilation holes 23 to fix the solar panel 701. Ventilation slots are provided on the sides of the transparent cover 22, and a downwardly bent waterproof pipe 24 is fixedly connected to the transparent cover 22 at the ventilation slot. The hot air inside the housing 1 can flow into the transparent cover 22 through the vent 23, and then be discharged to the outside through the waterproof pipe 24.

[0058] A battery management module 702 and a storage battery 703 are fixedly connected inside the housing 1. The battery management module 702 is electrically connected to the storage battery 703. The storage battery 703 is used to store the electrical energy converted by the solar panel 701 and deliver the electrical energy to power the drive component 4, the cooling fan 208, the control unit 5, and the temperature sensor 6. The power management module is used to manage the electrical energy conversion and storage between the solar panel 701 and the storage battery 703. It is also connected to the mains power and is configured to prioritize the use of solar power. When the battery 703's charge is lower than a set threshold, it automatically switches to mains power.

[0059] The implementation principle of this application embodiment is as follows: When the intelligent energy metering box is working, the heat generated by the electrical components inside the box 1 will cause the internal temperature to rise. Temperature sensors 6 distributed at different horizontal heights inside the box 1 detect the temperature at their respective locations in real time and transmit the detection signals to the control unit 5. The control unit 5 receives and compares the readings of each temperature sensor 6 to identify the highest temperature point inside the box 1 and its corresponding horizontal height.

[0060] The control unit 5 then sends a command to the drive component 4, which starts and drives the heat dissipation component 2 to slide along the strip grooves 8 on both sides of the housing 1 until the heat dissipation component 2 moves to the horizontal height area corresponding to the highest temperature point identified.

[0061] When the heat dissipation component 2 moves to the target position, the permanent magnet 18 at the end of its filter rod 203 interacts magnetically with the metal block 306 on the sealing plate 304 of the ventilation component 3 at the corresponding position. This magnetic force overcomes the elastic force of the return spring 302 of the ventilation column 303, attracting the ventilation column 303 to slide into the housing 1, causing the ventilation slot 15 on the ventilation column 303 to move to a position communicating with the through hole 11 of the fixing plate 301, thereby opening the ventilation component 3 at that location. Outside air enters the housing sequentially through the dustproof net 10, the air inlet 9 of the housing 1, the opened ventilation slot 15, and the through hole 11 of the fixing plate 301.

[0062] Simultaneously, the cooling fan 208 on the heat dissipation assembly 2 starts. Outside air is drawn in through the air inlet 17 on the filter rod 203, flows through the filter elements (such as dehumidifying sponge, dustproof cloth 204) inside the filter rod 203 for filtration and dehumidification. The purified air enters the hollow filter rod 203, flows through the rotating disk 205, and is finally blown out from the air outlet 21 on the air outlet frame 207, directly and directionally providing forced air cooling to the electrical components in the high-temperature area inside the box, achieving precise and efficient cooling.

[0063] Due to pressure changes and the drive of the cooling fan 208, the hot air inside the enclosure 1 rises and enters the transparent cover 22 through the exhaust hole 23 at the top of the enclosure 1. Finally, it is discharged outside the enclosure through the exhaust channel with the downward-bent waterproof pipe 24, forming a complete heat exchange cycle.

[0064] In terms of power supply, the solar panel 701 converts solar energy into electrical energy, which is stored in the battery 703 through the power management module. Priority is given to powering components such as the drive assembly 4, cooling fan 208, control unit 5, and temperature sensor 6, maximizing the utilization of green energy. The power management module monitors the battery 703's charge level in real time. When the charge level falls below a set threshold, it automatically switches to mains power, ensuring continuous, stable, and reliable operation of the system under any weather conditions.

[0065] In summary, this intelligent electricity metering box achieves precise and on-demand heat dissipation in high-temperature areas within the box through a series of coordinated steps including sensing, positioning, movement, opening, filtering, heat dissipation, ventilation, and intelligent power supply. This significantly improves heat dissipation efficiency and energy utilization, while effectively protecting against dust, moisture, and rainwater, achieving a comprehensive effect of environmental protection, energy saving, intelligent control, and stable reliability.
