[0002] Electricity metering devices are measuring instruments used to measure and record power generation, power supply (mutual supply), plant power consumption, line loss, and user power consumption. Electricity metering devices include electricity meters (single-phase electricity meters, three-phase electricity meters, multi-function electricity meters, smart prepaid electricity meters, active power meters, reactive power meters, maximum demand meters, multi-tariff electricity meters, etc.), metering terminals (data collectors, concentrators, distribution transformer monitoring and metering terminals, load control terminals, etc.), metering transformers (including voltage transformers and current transformers), and secondary connecting wires, etc. Electricity metering devices are generally installed in electricity metering boxes, which provide protection for the devices.

[0003] When using electricity metering boxes, filters are installed on both sides of the box to filter the air and prevent dust and impurities from entering the interior during heat dissipation. After prolonged use, a lot of dust and impurities accumulate on the filters. If not cleaned in time, this will affect the heat dissipation effect. Current cleaning methods typically involve manual cleaning with a brush, which allows dust and impurities to enter the box, making it very inconvenient to clean the internal electrical components. Furthermore, manual cleaning is not very effective and is cumbersome. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 7 This utility model provides an intelligent power metering box with self-cleaning function, including a box body 1 and a door 18 rotatably connected to the front end of the box body 1. Ventilation channels 11 are provided on both sides of the box body 1, and filters 7 are installed inside the ventilation channels 11. The filters 7 filter the air, reducing the entry of external dust and impurities into the box body 1. The box body 1 is connected to a spray mechanism for cleaning the filters 7. The spray mechanism includes a water tank 2, a water pump 3, four spray plates 6, and two cylinders 19. The water tank 2 is connected to the top of the box body 1. The suction end of the water pump 3 is connected to the water tank 2, and the discharge end is connected to the four spray plates 6. A water inlet is provided on the top of the water tank 2 for periodic water replenishment. Two spray plates 6 form a group, with one group cleaning a single filter 7. The two groups of spray plates 6 are distributed opposite each other. The spray plates 6 are movably connected to the box body 1, and the two spray plates 6 are interconnected. The cylinders 19 are used to drive the spray plates 6 to rise and fall.

[0024] A control panel is connected to the inside of the housing door 18, and the control panel is electrically connected to the water pump 3 and the cylinder 19. When cleaning the filter screen 7, the housing door 18 is opened, and the control panel is operated to control the operation of the water pump 3 and the cylinder 19.

[0025] Cylinder 19 drives two spray plates 6 to move downwards synchronously. The spray plates 6 slide relative to the guide frame 8 until the bottom of the spray plates 6 presses against the guide frame 8, at which point the spray plates 6 stop moving. At this time, the ventilation channel 11 is in a closed space to prevent sewage from overflowing during the rinsing process. Water pump 3 pumps water into the spray plates 6, so that the water is sprayed from the spray nozzle 16 onto the filter screen 7, which facilitates a thorough rinsing of the filter screen 7, improves the cleanliness of the filter screen 7, enhances the filtration effect, and is simple and convenient to operate.

[0026] Two drainage channels 9 are provided at the bottom of the ventilation channel 11. One drainage channel 9 has a drainage channel 10, and the other drainage channel 9 has a drain outlet 12 connected to the drainage channel 10. The cross-section of the drainage channel 9 is arc-shaped. The drainage channel 9 facilitates the collection of sewage into the middle of the drainage channel 9. Sewage from the inside of the filter screen 7 enters the drain outlet 12, then flows into the drainage channel 10, and finally is discharged from the bottom of the box 1.

[0027] Guide frames 8 are connected to the inner and outer sides of the housing 1. The water spray plate 6 is slidably connected to the guide frames 8 to improve the stability of the movement of the water spray plate 6. At the same time, the connection between the two is sealed to prevent sewage leakage.

[0028] The spraying mechanism also includes two water supply pipes 4, two corrugated pipes 5, multiple connecting blocks 14, multiple connecting channels 15, four inner cavities 17, and multiple spray nozzles 16. The discharge end of the water pump 3 is connected to the water supply pipes 4. The water supply pipes 4 are fixed to the housing 1, and the ends of the water supply pipes 4 are connected to the corrugated pipes 5. The corrugated pipes 5 are connected to the spray plate 6. The inner cavities 17 are located inside the spray plate 6. The multiple spray nozzles 16 are located on the inner side of the spray plate 6 and are connected to the inner cavities 17. The two ends of the connecting blocks 14 are connected to the two spray plates 6. The connecting channels 15 are located inside the connecting blocks 14 and are connected to the two inner cavities 17. The corrugated pipes 5 are extensible; when the spray plate 6 moves, the corrugated pipes 5 extend or retract. Water pump 3 delivers water through water pipe 4 and corrugated pipe 5 to the water spray plate 6 located on the outside. The two water spray plates 6 are interconnected, that is, the water spray plate 6 located on the inside is filled with water. The two water spray plates 6 spray each other, which facilitates the thorough rinsing and cleaning of the filter screen 7 and improves the cleanliness of the filter screen 7.

[0029] The two sides of the housing 1 are provided with sliding holes 13, and the connecting block 14 is slidably connected to the sliding holes 13. When the water spray plate 6 moves, it drives the connecting block 14 to slide in the sliding hole 13, which plays a good guiding role for the water spray plate 6. At the same time, the connecting block 14 enables the two water spray plates 6 to communicate with each other.

[0030] The water nozzles 16 are angled, and the direction of the water sprayed from the nozzles 16 forms a certain angle with the filter screen 7, thus performing an oblique flushing operation on the filter screen 7 and improving the rinsing effect. The water nozzles 16 of the two water spray plates 6 are staggered, so that the cleaning is more thorough.

[0031] Cylinder 19 is connected to housing 1, and the power output end of cylinder 19 is connected to water spray plate 6.

[0032] Working principle: When cleaning the filter screen 7, the cylinder 19 drives the two spray plates 6 to move down synchronously, and the spray plates 6 slide relative to the guide frame 8. The spray plates 6 stop moving when they press against the guide frame 8, at which point the ventilation channel 11 is in a closed space. The water pump 3 injects water from the water tank 2 into the spray plates 6 through the water supply pipe 4 and corrugated pipe 5. Water is then sprayed from multiple nozzles 16 onto the filter screen 7, facilitating a thorough cleaning of both sides of the filter screen 7 and improving its cleanliness. The drainage channel 9 collects wastewater in its center, allowing it to drain out through the drainage channel 10. After the filter screen 7 is cleaned, the cylinder 19 drives the two spray plates 6 to move back up synchronously, at which point the ventilation channel 11 opens, and the power metering box resumes normal operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
