Description

Technical Field

[0001] This invention relates to the field of metering box technology, and in particular to an electrical energy metering box with a dustproof mechanism. Background Technology

[0002] As the core equipment used to measure electricity consumption in the power system, the electricity metering box is widely used in various scenarios such as residential communities, industrial plants, and commercial buildings. It integrates precision electrical components such as electricity meters, transformers, and terminals. The stable operation of these components directly determines the accuracy and reliability of electricity metering.

[0003] In the actual use of electricity metering boxes, heat dissipation and dust prevention are two key issues affecting their operational stability. On the one hand, the electrical components inside the box continuously generate heat during operation. If this heat cannot be dissipated in time, the internal temperature will rise, which will not only affect the metering accuracy of precision components but also accelerate component aging, leading to safety hazards such as short circuits and burnout. On the other hand, dust and particulate matter from the external environment can easily enter the box through the heat dissipation vents, adhering to the surface of electrical components and wiring points, causing a decrease in component insulation performance and poor contact, which will also affect the normal operation and service life of the metering box.

[0004] To address these issues, existing electricity metering boxes typically incorporate filters at the vents to block dust, while simultaneously relying on natural ventilation through these vents or forced ventilation via fans. However, these existing solutions have significant drawbacks. They struggle to balance dust prevention with efficient heat dissipation and are costly to maintain. Regarding dust prevention, after prolonged use, the filter's pores become clogged with dust, reducing airflow and weakening heat dissipation. Furthermore, the increased air pressure difference across the filter makes it easier for dust to penetrate, and some fine dust particles may even accumulate within the filter pores, making them difficult to clean. Existing cleaning methods mostly involve manual periodic disassembly and cleaning or replacement of filters, requiring downtime for operation. This is not only time-consuming and labor-intensive, increasing maintenance costs, but also potentially damaging the metering box's sealing performance or internal components due to improper operation during disassembly and installation. Some metering boxes with automatic cleaning functions only use a single brush scraping structure, which can only remove surface dust from the filter screen and cannot effectively unclog blocked pores, resulting in poor cleaning performance. Furthermore, dust can easily fall back into the box during the scraping process, causing secondary pollution. In terms of heat dissipation, existing heat dissipation structures are mostly fixed-position fans or vents, with limited airflow coverage, easily creating heat dissipation dead zones and failing to provide uniform heat dissipation to all electrical components inside the box, leading to damage to some components due to localized overheating. At the same time, filter blockage further hinders airflow, causing heat dissipation efficiency to gradually decrease over time, creating a vicious cycle. In addition, the dustproof and heat dissipation mechanisms of existing metering boxes are mostly independent design modules, lacking coordination and even having functional conflicts, making it impossible to achieve simultaneous optimization of dustproofing and heat dissipation. Therefore, this application proposes an energy metering box with a dustproof mechanism. Summary of the Invention

[0005] The purpose of this invention is to address the problems of poor dustproof and heat dissipation effects in the prior art by proposing an energy metering box with a dustproof mechanism.

[0008] Optionally, the heat dissipation mechanism includes a second gear rotatably mounted inside the housing, the second gear meshing with a first gear, an air outlet plate slidably mounted inside the housing, the air outlet plate being a cavity, a plurality of nozzles arranged at equal intervals fixedly mounted on the air outlet plate, a connecting shaft fixedly mounted on the second gear, a second reciprocating screw fixedly mounted at one end of the connecting shaft, the second reciprocating screw being threadedly connected to one side of the air outlet plate, a third connecting pipe fixedly mounted on one side of the blower, a micro compressor fixedly mounted on the third connecting pipe, and one end of the micro compressor being fixedly connected to the air outlet plate.

[0009] Optionally, a limiting plate is fixedly installed on one side of the connecting plate, and the limiting plate is slidably connected to the inner wall of the box.

[0010] Optionally, a fixing plate is fixedly installed on one side of the guide frame, and one end of the fixing plate is fixedly connected to the box body.

[0011] Optionally, a first spring is fixedly installed on one side of the mounting block, and one end of the first spring is fixedly connected to the cleaning plate.

[0012] Optionally, a motor is fixedly installed on the housing, and the output shaft of the motor is fixedly connected to the first gear.

[0013] Optionally, a second spring is fixedly installed inside the heat dissipation vent, one end of the second spring is fixedly connected to the mounting frame, a dust guide groove is provided inside the heat dissipation vent, and a dust outlet is provided on one side of the box body, with the dust guide groove communicating with the dust outlet.

[0014] Optionally, a guide groove is provided inside the box, and a positioning rod is fixedly installed on one side of the air outlet plate, the positioning rod being slidably connected to the guide groove.

[0015] Optionally, a sealing door is hinged to one side of the housing, and a sealing gasket is provided on the sealing door.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This invention designs a reciprocating motion mechanism for a cleaning plate driven by a first gear, a first reciprocating lead screw, a connecting plate, a guide plate, and a slider. The unclogging block on the cleaning plate can directly physically unclog the filter screen holes. At the same time, a blower supplies air to the cavity of the cleaning plate through a connecting pipe. The airflow is ejected from the air outlet, blowing the unclogged dust away from the outside of the filter screen, thus completely solving the problem of filter screen pore blockage. A first spring is set between the mounting block and the cleaning plate, so that the cleaning plate has a buffering effect when it hits the filter screen, which not only ensures effective contact between the unclogging block and the filter screen, but also avoids damage to the filter screen caused by rigid collision, thereby improving the service life of the equipment.

[0018] Furthermore, the first gear drives the second gear to rotate, which in turn drives the second reciprocating screw to rotate, causing the air outlet plate to make vertical reciprocating motion in the vertical direction. In conjunction with the blower, the gas is delivered into the third connecting pipe, and then the micro compressor cools the gas. Finally, the gas is sprayed out from the nozzle on the air outlet plate to fully dissipate heat from the internal workpiece.

[0019] Furthermore, the cooling airflow increases the air pressure inside the chamber, causing the airflow to flow outward from the filter screen at the heat dissipation vent. This airflow direction is consistent with the blowing airflow direction of the unblocking mechanism, further assisting in the removal of dust from the filter screen surface and improving the filter screen unblocking effect. At the same time, the cleaned filter screen remains unobstructed, ensuring the efficiency of heat dissipation airflow and resolving the functional conflict between dust prevention and heat dissipation.

[0020] This invention achieves full dust protection for the electricity metering box, avoids filter clogging, improves the heat dissipation efficiency of internal components, and extends the service life of the equipment. Attached Figure Description

[0035] Example 1

[0036] like Figure 1 , Figure 2 and Figure 3As shown, the present invention proposes an electricity metering box with a dustproof mechanism, including a box body 1 and a heat dissipation port 5. The heat dissipation port 5 is opened on both sides of the box body 1. A mounting frame 6 is slidably installed in the heat dissipation port 5. A filter screen 8 is fixedly installed on the mounting frame 6 to prevent external dust from entering the box body 1. A dredging mechanism for unblocking the heat dissipation port 5 is provided in the box body 1. A heat dissipation mechanism for fully dissipating heat from the internal components is provided in the box body 1.

[0037] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the unblocking mechanism includes a guide frame 17 fixedly installed inside the housing 1. Slider blocks 18 are symmetrically slidably mounted on the guide frame 17. A guide plate 16 is hinged to the slider 18. A first gear 13 is rotatably mounted inside the housing 1. A first reciprocating screw 14 is fixedly mounted on the first gear 13. A connecting plate 12 is slidably mounted inside the housing 1. The connecting plate 12 is threadedly connected to the first reciprocating screw 14. The bottom sides of the connecting plate 12 are hinged to the guide plate 16. A fixing rod 19 is fixedly mounted on one end of the slider 18. One end of the fixing rod 19 is fixed... A mounting block 20 is fixedly installed, and a cleaning plate 21 is slidably installed on one side of the mounting block 20. Multiple equidistant unblocking blocks are fixedly installed on the cleaning plate 21. The cleaning plate 21 is hollow and has multiple equidistant air outlets 23. A blower 26 is fixedly installed on the housing 1. A first connecting pipe 24 is fixedly installed on one side of the blower 26. One end of the first connecting pipe 24 is connected to one of the cleaning plates 21. A second connecting pipe 25 is fixedly installed on the first connecting pipe 24. The second connecting pipe 25 is connected to... Another cleaning plate 21 is connected. When the filter needs to be unclogged, the first gear 13 is rotated, which drives the first reciprocating screw 14 to rotate. Since the connecting plate 12 is slidably connected to the inner wall of the housing 1, when the first reciprocating screw 14 rotates, the connecting plate 12 reciprocates in the vertical direction. The connecting plate 12 drives the guide plates 16 on both sides to squeeze or pull the slider 18 in the guide frame 17, so that the slider 18 reciprocates horizontally in the guide frame 17. The slider 18 drives the cleaning plate on one side of the mounting block 20 to move. When the plates 21 move together, the blower 26 is activated. The blower 26 delivers air to the first connecting pipe 24, then to the second connecting pipe 25, and finally to the cleaning plate 21, where it is discharged through the air outlet 23. In conjunction with the slider 18, the cleaning plate 21 continuously beats the filter screen 8. The unblocking blocks on the cleaning plate 21 unblock the holes in the filter screen 8, and the dust is pushed to the outside of the filter screen 8 by the unblocking blocks, preventing the filter screen from clogging. At the same time, the airflow discharged from the air outlet 23 helps to blow the airflow outward, improving the unblocking effect.

[0038] Example 2

[0039] like Figure 1-6As shown, the heat dissipation mechanism includes a second gear 15 rotatably mounted inside the housing 1, which meshes with a first gear 13. An air outlet plate 30 is slidably mounted inside the housing 1. The air outlet plate 30 is a cavity, and multiple nozzles 31 arranged at equal intervals are fixedly mounted on it. A connecting shaft 33 is fixedly mounted on the second gear 15, and a second reciprocating screw 29 is fixedly mounted at one end of the connecting shaft 33. The second reciprocating screw 29 is threadedly connected to one side of the air outlet plate 30. A third connecting pipe 27 is fixedly mounted on one side of the blower 26, and a miniature compressor 28 is fixedly mounted on the third connecting pipe 27. One end of the miniature compressor 28 is fixedly connected to the air outlet plate 30. The first gear... Rotation of 13 drives rotation of the second gear 15, which in turn drives rotation of the second reciprocating screw 29. Since the air outlet plate 30 is slidably connected to the inner wall of the housing 1, the second reciprocating screw 29 drives the air outlet plate 30 to make vertical reciprocating motion within the housing 1. This, in conjunction with the blower 26, delivers air to the third connecting pipe 27. The micro compressor 28 is then activated to cool the gas in the third connecting pipe 27, which is then sprayed out from the nozzle 31 on the air outlet plate 30. This reciprocating motion of the air outlet plate 30 effectively dissipates heat from the internal components. As the gas is sprayed out from the nozzle 31, the internal air pressure increases, causing the gas to flow outward from the filter screen 8, improving the unblocking effect of the filter screen 8 and carrying away excess dust.

[0040] Example 3

[0041] like Figure 4 , Figure 5 and Figure 6 As shown, a limiting plate 11 is fixedly installed on one side of the connecting plate 12, and the limiting plate 11 is slidably connected to the inner wall of the housing 1. A fixing plate 10 is fixedly installed on one side of the guide frame 17, and one end of the fixing plate 10 is fixedly connected to the housing 1. A first spring 22 is fixedly installed on one side of the mounting block 20, and one end of the first spring 22 is fixedly connected to the cleaning plate 21. A motor 3 is fixedly installed on the housing 1, and the output shaft of the motor 3 is fixedly connected to the first gear 13. A second spring 7 is fixedly installed inside the heat dissipation vent 5. One end is fixedly connected to the mounting frame 6. A dust guide groove 9 is provided inside the heat dissipation vent 5. A dust outlet 4 is provided on one side of the box body 1. The dust guide groove 9 is connected to the dust outlet 4. A guide groove 32 is provided inside the box body 1. Dust falling from the filter screen 8 enters the dust guide groove 9. The dust guide groove 9 transports the dust to the dust outlet 4 for discharge, avoiding accumulation at the heat dissipation vent 5. A positioning rod is fixedly installed on one side of the air outlet plate 30. The positioning rod is slidably connected to the guide groove 32. A sealing door 2 is hinged on one side of the box body 1. A sealing gasket is provided on the sealing door 2.

[0042] Working principle: When the filter needs to be unclogged, the first gear 13 is rotated, which drives the first reciprocating screw 14 to rotate. Since the connecting plate 12 is slidably connected to the inner wall of the housing 1, when the first reciprocating screw 14 rotates, the connecting plate 12 reciprocates vertically. The connecting plate 12 drives the guide plates 16 on both sides to squeeze or pull the slider 18 in the guide frame 17, causing the slider 18 to reciprocate horizontally within the guide frame 17. The slider 18 drives the cleaning plate 21 on one side of the mounting block 20 to move together, starting the blower 26. The blower 26 delivers air to the first connecting pipe 24, then to the second connecting pipe 25, and finally to the cleaning plate 21, which is discharged through the air outlet 23. The slider 18, together with the cleaning plate 21, continuously beats the filter 8. The unclogging blocks on the cleaning plate 21 unclog the holes of the filter 8, and the dust is pushed to the outside of the filter 8 by the unclogging blocks, avoiding... The filter screen is free from clogging, and the airflow discharged from the air outlet 23 helps to blow the air outward, improving the unblocking effect. The rotation of the first gear 13 drives the rotation of the second gear 15, which in turn drives the rotation of the second reciprocating screw 29. Since the air outlet plate 30 is slidably connected to the inner wall of the housing 1, the second reciprocating screw 29 drives the air outlet plate 30 to make vertical reciprocating motion in the housing 1. Together with the blower 26, the air is delivered to the third connecting pipe 27. The micro compressor 28 is started to cool the gas in the third connecting pipe 27, and then spray it out from the nozzle 31 on the air outlet plate 30. Together with the reciprocating motion of the air outlet plate 30, the internal components are fully cooled. Since the gas is sprayed out from the nozzle 31, the internal air pressure increases, and the gas flows outward from the filter screen 8, improving the unblocking effect of the filter screen 8 and carrying away excess dust. The dust falling from the filter screen 8 enters the dust guide groove 9, which transports the dust to the dust outlet 4 for discharge, avoiding accumulation at the heat dissipation vent 5.

[0043] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
