Technical Field
[0001] This invention relates to the field of smart grid technology, specifically to an energy-saving power metering box with automatic temperature control for smart grids. Background Technology
[0002] Energy-saving metering boxes with automatic temperature control for smart grids are core outdoor equipment in smart power distribution systems, responsible for electricity metering, data acquisition, and operational status monitoring. They ensure a stable and suitable working environment for the internal metering devices while achieving refined control of energy consumption. However, during long-term outdoor operation, the scale of willow and poplar catkin dispersal increases year by year due to changes in the natural environment. Especially during peak catkin outbreaks, large amounts of lightweight catkins continuously adhere to and accumulate at the heat dissipation air inlet of the metering box, gradually causing blockage of the air intake channel. This directly leads to a significant decrease in the effective airflow of the temperature control system, resulting in a reduction in the heat exchange efficiency inside the box. To maintain the preset temperature control standard and prevent internal components from malfunctioning due to high temperatures, the heat dissipation system can only passively increase the fan power and increase the airflow. This operating mode is not ideal. This not only completely negates the original energy-saving design effect of the equipment, but also generates additional power consumption, increasing the overall operation and maintenance cost of the power grid. Currently, the main method for dealing with the blockage of air inlets by flying catkins is still manual cleaning. However, power metering boxes are generally characterized by a wide distribution, a large number of installations, and scattered locations, making manual inspection and cleaning difficult. Moreover, the temperature is high during the peak period of flying catkins, which significantly increases the heat dissipation demand inside the metering box. The cooling fan starts and stops more frequently, and the continuous airflow adsorption at the air inlet accelerates the accumulation of flying catkins. After cleaning, the air inlet is very likely to be blocked again in a short period of time, making it impossible to form a long-term stable heat dissipation guarantee. This seriously affects the outdoor operation reliability and actual energy-saving benefits of automatic temperature-controlled energy metering boxes. Therefore, this invention provides an automatic temperature-controlled energy metering box for smart grids. Summary of the Invention
[0003] The purpose of this invention is to provide an energy-saving power metering box with automatic temperature control for smart grids, so as to solve the problems mentioned in the background art.
[0004] The technical solution of this invention is: an energy-saving electricity metering box with automatic temperature control for smart grids, comprising a metering box body and an accessory box, which are connected by fasteners. The accessory box has a filter slot permeating its inner cavity on one end. An end-side collection box is slidably disposed within the accessory box cavity. An assembly frame is fixedly installed on the side of the end-side collection box. A ring frame is rotatably connected between the inner walls of the assembly frame. Several sliding grooves are evenly spaced on the outer circumference of both ends of the ring frame. A movable block is slidably disposed in each sliding groove. An anti-stick polyester filter screen is disposed between the movable blocks. A rigid roller is rotatably connected to the inner cavity of the accessory box. A Teflon scraper is slidably disposed on the outer circumference of the rigid roller. This invention can effectively address the adverse effects of high pollen density on the heat dissipation and operation of the electricity metering box. During periods of concentrated pollen outbreaks, the accessory box is fixedly installed at the bottom of the metering box body, allowing the corresponding pipes inside the metering box body to... The connection between the road and the accessory box is seamless, allowing for functional expansion without altering the original main structure of the metering box. It boasts excellent installation convenience and equipment compatibility. Once operational, it can clean and collect the lint adhering to the surface of the anti-stick polyester filter screen according to a preset cycle, continuously ensuring the unobstructed flow of the heat dissipation air intake channel. This reduces airflow resistance and heat exchange efficiency degradation caused by lint accumulation, preventing the cooling fan from running at high speed due to insufficient temperature control airflow, thus reducing additional energy consumption and equipment wear and tear. This allows the metering box's original automatic temperature control energy-saving effect to be maintained stably. After the lint infestation period ends, the accessory box can be completely unloaded from the metering box, and the lint collected inside can be cleaned uniformly. This reduces the difficulty and maintenance cost of decentralized manual cleaning and does not interfere with the normal operation of the metering box during non-lint periods, effectively improving the operational stability and overall energy-saving benefits of the outdoor energy-saving metering box in environments with high lint incidence.
[0005] Preferably, a temperature-controlled fan unit is fixedly installed on the top of the inner cavity of the metering box. A diversion duct and a return duct are respectively connected to the side walls at both ends of the temperature-controlled fan unit. The ends of the diversion duct and the return duct that are away from the temperature-controlled fan unit extend into the inner cavity of the accessory box and are rotatably connected to the air inlet and air outlet of the corresponding rigid roller.
[0006] Preferably, a first vertical plate is fixedly installed at the bottom of the inner cavity of the accessory box, an electric telescopic rod is fixedly installed on the side wall of the first vertical plate, and the telescopic end of the electric telescopic rod is fixedly connected to the side wall of the end collection box. A flexible hose is connected to the air outlet at the end of the assembly frame. An inverted conical air outlet pipe communicating with the inner cavity of the metering box is connected to the side of the flexible hose away from the assembly frame. A roller dot spraying module is fixedly installed at the top of the inner cavity of the accessory box.
[0007] Preferably, a second vertical plate is fixedly installed on the top of the inner cavity of the accessory box, a drive motor is fixedly installed on the side wall of the second vertical plate, a drive gear is fixedly installed at the output end of the drive motor, and a driven gear ring meshing with the drive gear is fixedly sleeved on the outer circumference of the rigid roller. During operation, the device starts the automatic lint removal program according to a preset cycle. The electric telescopic rod first drives the end-side collection box, assembly frame, ring frame and anti-stick polyester filter screen to retract from the filter slot hole into the inner cavity of the accessory box. At the same time, the end of the assembly frame seals the connection between the filter slot hole and the inner cavity of the accessory box to prevent debris from entering the inner cavity of the accessory box in the opposite direction during the lint removal process. Then, the roller dot spraying module evenly sprays sticky adhesive particles onto the surface of the rigid roller below. At the same time, the drive motor drives the drive gear to rotate. Through gear meshing, the driven gear ring and the rigid roller rotate synchronously. When the rigid roller with sticky adhesive particles on its surface sweeps over the surface of the anti-stick polyester filter screen, the adhesive force transfers the flying lint on the surface of the filter screen to its own roller surface.
[0008] Preferably, an annular sleeve is fixedly fitted on the outer circumference of the rigid roller, and a plurality of return springs are circumferentially connected at equal angles between the annular sleeve and the Teflon scraper, and a push plate is fixedly installed in the inner cavity of the end-side collection box.
[0009] Preferably, a finger ring sleeve is fixedly fitted on the side wall of the rigid roller, and a vertical blade is fixedly installed on the top of the finger ring sleeve. An end-side motor is fixedly installed on the side wall of the end-side collection box, and a shaft is fixedly installed at the output end of the end-side motor. Several scraping cranks are welded to the shaft body at equal angles. After the fly lint on the filter screen surface is removed, the electric telescopic rod drives the cleaned anti-stick polyester filter screen to extend back to the filter groove hole, restoring the filtration and heat dissipation function. During the synchronous process of filter screen resetting, the push plate inside the assembly frame continuously pushes the Teflon scraper to move axially along the roller surface. During the movement, the Teflon scraper simultaneously scrapes off the fly lint and residual sticky particles adhering to the surface of the rigid roller. Under the continuous pushing action, the fly lint gradually gathers and rolls up to form an annular fly lint ring. Thanks to the low surface energy characteristics of Teflon material, the sticky particles do not easily adhere to the scraper surface, ensuring the scraping operation. The continuous effectiveness of the process; throughout the entire heat dissipation operation, part of the hot air discharged from the temperature-controlled fan unit is introduced into the hollow cavity of the rigid roller through the diversion duct, and then discharged back through the return duct. The residual heat of the heat dissipation is used to maintain the surface temperature of the rigid roller within a suitable range, preventing the sticky particles from solidifying and failing due to the low ambient temperature. At the same time, the suitable temperature range can coordinate with the scraping operation of the Teflon scraper to prevent the solidified sticky particles from hindering the axial movement of the Teflon scraper. When the anti-stick polyester filter screen is completely reset to the filter slot position, the annular fly lint ring also moves to the corresponding position of the vertical blade with the push of the Teflon scraper. Then, the end-side motor drive shaft and the scraping crank rotate. The rotating scraping crank pulls the annular fly lint ring, and with the cutting action of the vertical blade, the annular fly lint ring breaks and falls off, finally falling into the collection trough of the end-side collection box, completing the single-cycle fly lint cleaning and collection operation.
[0010] Preferably, two symmetrical third vertical plates are fixedly installed on the inner side of the assembly frame. Two symmetrical vertical rods are slidably arranged on the top of each of the two third vertical plates. A side plate is welded between the top of each pair of adjacent vertical rods. A retaining spring is wound around the body of each vertical rod, and several retaining springs are respectively connected between the corresponding side plate and the corresponding vertical plate. A flexible roller is rotatably connected between the two side plates. During the lint removal process, the anti-stick polyester filter screen, with its own flexibility, combined with the movable connection structure formed by the movable blocks at both ends and the side wall of the ring frame, and the push of the flexible roller on the inner side of the ring frame by the retaining spring, pushes the anti-stick polyester filter screen towards the rigid roller, so that the filter screen and the roller surface are closely attached, which enhances the adhesion and removal effect of the flying lint. At the same time, the adhesion force of the roller surface brought by the sticky particles and the retaining force of the flexible roller together increase the friction between the filter screen and the rigid roller, so that when the rigid roller rotates, it can drive the anti-stick polyester filter screen and the ring frame to rotate synchronously, so as to achieve full coverage cleaning of the entire outer circumference of the filter screen.
[0011] This invention provides an energy-saving electricity metering box with automatic temperature control for smart grids, which has the following improvements and advantages compared with the prior art: This invention effectively addresses the adverse effects of high pollen density on the heat dissipation and operation of electricity metering boxes. During periods of concentrated pollen outbreaks, the accessory box is fixedly installed at the bottom of the metering box, allowing for seamless connection between the corresponding internal piping and the accessory box. This functional expansion is achieved without altering the original structure of the metering box, offering excellent installation convenience and equipment compatibility. After commissioning, it can clean and collect pollen adhering to the surface of the anti-stick polyester filter screen at preset intervals, continuously ensuring the unobstructed flow of the heat dissipation air intake channel and mitigating the airflow resistance and reduced heat exchange efficiency caused by pollen accumulation. This design avoids forcing the cooling fan to run continuously at high speed due to insufficient airflow for temperature control, reducing additional energy consumption and equipment wear and tear, and allowing the metering box to maintain its original automatic temperature control energy-saving effect stably. After the period of excessive fluff, the accessory box can be completely unloaded from the main body of the metering box, and the fluff collected inside can be cleaned in a unified manner. This reduces the difficulty and maintenance cost of decentralized manual cleaning, and will not interfere with the normal operation of the metering box during non-fluff periods. This effectively improves the operational stability and overall energy-saving benefits of outdoor energy-saving metering boxes in environments with high fluff incidence. Attached Figure Description

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.
[0015] This invention provides an improved, energy-saving electricity metering box with automatic temperature control for smart grids. The technical solution of this invention is as follows: like Figures 1-11As shown, an energy-saving electricity metering box with automatic temperature control for smart grids includes a metering box body 1 and an accessory box 2, which are connected by fasteners. The accessory box 2 has a filter slot 36 penetrating its inner cavity on one end. An end-side collection box 3 is slidably disposed within the inner cavity of the accessory box 2. An assembly frame 4 is fixedly installed on the side of the end-side collection box 3. A ring frame 5 is rotatably connected between the inner walls of the assembly frame 4. Several sliding grooves 6 are evenly spaced on the outer circumference of both ends of the ring frame 5. A movable block 7 is slidably disposed within each sliding groove 6. An anti-stick polyester filter screen 8 is installed between the movable blocks 7. A rigid roller 9 is rotatably connected to the inner cavity of the accessory box 2. A Teflon scraper 10 is slidably installed on the outer circumference of the rigid roller 9. A temperature-controlled fan unit 11 is fixedly installed at the top of the inner cavity of the metering box body 1. A diversion duct 12 and a return duct 13 are respectively connected to the side walls at both ends of the temperature-controlled fan unit 11. The ends of the diversion duct 12 and the return duct 13 away from the temperature-controlled fan unit 11 extend into the inner cavity of the accessory box 2 and are rotatably connected to the air inlet and air outlet of the corresponding rigid roller 9. The installation of the device is completed before the peak period of fluff outbreak. The accessory box 2 is fixed to the bottom of the metering box body 1 with fasteners, so that the diversion air duct 12 and the return air duct 13 are rotatably connected to the air inlet and air outlet of the rigid roller 9, respectively. At the same time, the air outlet of the inverted conical air outlet duct 17 is connected to the original bottom air inlet of the metering box body 1, completing the installation and layout of the entire auxiliary lint removal and heat dissipation device. After the device is put into operation, the temperature sensor on the inner wall of the metering box body 1 monitors the ambient temperature inside the box in real time. When the temperature inside the box rises to the heat dissipation trigger range, the central control component starts the temperature control fan unit 11 to run. The airflow carrying fluff flows through the anti-stick polyester filter 8 under negative pressure and enters the interior of the ring frame 5. The fluff is blocked and intercepted on the outer surface of the filter. The filtered clean airflow enters the airflow channel inside the assembly frame 4 through the fan-shaped air holes on the side wall of the ring frame 5. It then passes through the flexible hose 16 and the inverted cone-shaped air outlet 17 in sequence, and is finally sent into the box through the air inlet at the bottom of the metering box body 1 to complete heat dissipation. It should be noted that under normal heat dissipation conditions, the assembly frame 4, the ring frame 5 and the anti-stick polyester filter 8 are all located in the filter slot 36 at the end of the accessory box 2 to ensure the smooth and stable air intake path.
[0016] Furthermore, a first vertical plate 14 is fixedly installed at the bottom of the inner cavity of the accessory box 2, and an electric telescopic rod 15 is fixedly installed on the side wall of the first vertical plate 14. The telescopic end of the electric telescopic rod 15 is fixedly connected to the side wall of the end collection box 3. A flexible hose 16 is connected to the air outlet at the end of the assembly frame 4. An inverted conical air outlet pipe 17 communicating with the inner cavity of the metering box body 1 is connected to the side of the flexible hose 16 away from the assembly frame 4. A roller dot spraying module 18 is fixedly installed at the top of the inner cavity of the accessory box 2. A second vertical plate 19 is fixedly installed at the top of the inner cavity of the accessory box 2. A drive motor 20 is fixedly installed on the side wall of the second vertical plate 19. An active motor is fixedly installed at the output end of the drive motor 20. Gear 21, a driven gear ring 22 that meshes with the driving gear 21 is fixedly sleeved on the outer circumference of the rigid roller 9, two symmetrical third vertical plates 31 are fixedly installed on the inner side of the assembly frame 4, two symmetrical vertical rods 32 are slidably arranged on the top of each of the two third vertical plates 31, a side plate 33 is welded between the top of each pair of adjacent vertical rods 32, abutment spring 34 is wound around the body of each vertical rod 32, and several abutment springs 34 are respectively connected between the corresponding side plate 33 and the corresponding vertical plate, a flexible roller 35 is rotatably connected between the two side plates 33, during operation the device starts the automatic lint removal program according to the preset cycle, the electric telescopic rod 15 first drives the end side collection Box 3, assembly frame 4, ring frame 5, and anti-stick polyester filter screen 8 are retracted from the filter slot 36 into the inner cavity of accessory box 2. Simultaneously, the end of assembly frame 4 seals the connection between filter slot 36 and the inner cavity of accessory box 2, preventing debris from reversing into the inner cavity of accessory box 2 during the lint removal process. Then, roller dot spraying module 18 evenly sprays adhesive particles onto the surface of the rigid roller 9 below. Simultaneously, drive motor 20 drives drive gear 21 to rotate, which in turn drives driven gear ring 22 to rotate synchronously with the rigid roller 9 through gear meshing. As the rigid roller 9, with adhesive particles adhering to its surface, passes over the anti-stick polyester filter screen 8, the adhesive force transfers the lint adhering to the filter screen surface to its own surface. During the lint removal process, the anti-stick polyester filter screen 8, with its own flexibility and the movable connection structure formed by the movable blocks 7 at both ends and the side wall of the ring frame 5, plus the push force of the flexible roller 35 on the inner side of the ring frame 5 against the spring 34, pushes the anti-stick polyester filter screen 8 towards the rigid roller 9, so that the filter screen and the roller surface are closely attached, which enhances the sticking and removal effect of flying lint. At the same time, the adhesion force of the roller surface brought by the sticky particles and the pressure of the flexible roller 35 together increase the friction between the filter screen and the rigid roller 9, so that when the rigid roller 9 rotates, it can drive the anti-stick polyester filter screen 8 and the ring frame 5 to rotate synchronously, realizing the full coverage cleaning of the entire outer circumference of the filter screen.
[0017] Furthermore, an annular sleeve 23 is fixedly fitted on the outer circumference of the rigid roller 9. Several return springs 24 are circumferentially connected between the annular sleeve 23 and the Teflon scraper 10 at equal angles. A push plate 25 is fixedly installed in the inner cavity of the end-side collection box 3. A finger ring sleeve 26 is fixedly fitted on the side wall of the rigid roller 9. A vertical blade 27 is fixedly installed on the top of the finger ring sleeve 26. An end-side motor 28 is fixedly installed on the side wall of the end-side collection box 3. A shaft 29 is fixedly installed at the output end of the end-side motor 28. Several return springs 24 are circumferentially welded on the shaft 29 at equal angles. After the material-removing crank 30 completes the removal of fly lint from the filter screen surface, the electric telescopic rod 15 drives the cleaned anti-stick polyester filter screen 8 to extend back to the filter slot 36, restoring the filtration and heat dissipation function. During the synchronous process of filter screen resetting, the push plate 25 inside the assembly frame 4 continuously pushes the Teflon scraper 10 to move axially along the roller surface. During this movement, the Teflon scraper 10 simultaneously scrapes away the fly lint and residual sticky particles adhering to the surface of the rigid roller 9. Under continuous pushing action, the fly lint gradually gathers and rolls up to form an annular fly lint ring, benefiting from... The low surface energy of Teflon material prevents sticky particles from adhering to the scraper surface, ensuring the continuous effectiveness of the scraping operation. Throughout the cooling process, a portion of the hot air discharged from the temperature-controlled fan unit 11 is guided through the diversion duct 12 into the hollow cavity of the rigid roller 9, and then discharged back through the return duct 13. This utilizes residual heat to maintain the surface temperature of the rigid roller 9 within a suitable range, preventing the sticky particles from solidifying and failing due to excessively low ambient temperatures. Simultaneously, this suitable temperature range coordinates with the scraping operation of the Teflon scraper 10, preventing solidification. The sticky particles hinder the axial movement of the Teflon scraper 10. When the anti-stick polyester filter screen 8 is fully reset to the filter slot 36 position, the annular fly lint ring also moves to the corresponding position of the vertical blade 27 with the push of the Teflon scraper 10. Then, the end-side motor 28 drives the shaft 29 and the material-removing crank 30 to rotate. The rotating material-removing crank 30 pulls the annular fly lint ring, and with the cutting action of the vertical blade 27, the annular fly lint ring breaks and falls off, finally falling into the collection slot of the end-side collection box 3, completing the single-cycle fly lint cleaning and collection operation.
[0018] Working principle: Before the peak period of fluff outbreak, the device is assembled and the accessory box 2 is fixed to the bottom of the metering box body 1 with fasteners. The diversion air pipe 12 and the return air pipe 13 are respectively connected to the air inlet and air outlet of the rigid roller 9. At the same time, the air outlet of the inverted cone-shaped air outlet pipe 17 is connected to the original bottom air inlet of the metering box body 1, thus completing the installation and layout of the entire auxiliary fluff removal and heat dissipation device. After the device is put into operation, the temperature sensor on the inner wall of the metering box 1 monitors the ambient temperature inside the box in real time. When the temperature inside the box rises to the heat dissipation trigger range, the central control component starts the temperature control fan unit 11. The airflow carrying flying fluff flows through the anti-stick polyester filter 8 under negative pressure and enters the interior of the ring frame 5. The flying fluff is blocked and intercepted on the outer surface of the filter. The filtered clean airflow enters the airflow channel inside the assembly frame 4 through the fan-shaped air holes on the side wall of the ring frame 5, and then passes through the flexible hose 16 and the inverted cone-shaped air outlet pipe 17 in sequence, finally passing through the bottom of the metering box 1. Air is introduced into the box through the inlet to complete heat exchange. It should be noted that under normal heat dissipation conditions, the assembly frame 4, the ring frame 5, and the anti-stick polyester filter 8 are all located within the filter slot 36 at the end of the accessory box 2, ensuring a smooth and stable air intake path. During operation, the device starts the automatic lint removal program according to the preset cycle. The electric telescopic rod 15 first drives the end-side collection box 3, the assembly frame 4, the ring frame 5, and the anti-stick polyester filter 8 to retract from the filter slot 36 into the inner cavity of the accessory box 2. At the same time, the end of the assembly frame 4 seals the connection between the filter slot 36 and the inner cavity of the accessory box 2. To prevent debris from reversing and entering the inner cavity of the accessory box 2 during the lint removal process, the roller dot spraying module 18 then evenly sprays adhesive particles onto the surface of the rigid roller 9 below. Simultaneously, the drive motor 20 drives the drive gear 21 to rotate, which in turn drives the driven gear ring 22 to rotate synchronously with the rigid roller 9. As the rigid roller 9, with its adhesive particles adhering to its surface, passes over the anti-stick polyester filter screen 8, the adhesive force transfers the lint adhering to the filter screen surface to its own roller surface. During the lint removal process, the anti-stick polyester filter screen 8, with its inherent flexibility, cooperates with the two ends via flexible... The movable connection structure formed by the moving block 7 and the side wall of the ring frame 5, together with the flexible roller 35 inside the ring frame 5 under the pushing force of the abutting spring 34, pushes the anti-stick polyester filter screen 8 towards the rigid roller 9, so that the filter screen and the roller surface are closely attached, which enhances the sticking and removal effect of flying lint. At the same time, the adhesion force of the roller surface brought by the sticky particles and the abutting force of the flexible roller 35 together increase the friction between the filter screen and the rigid roller 9, so that when the rigid roller 9 rotates, it can drive the anti-stick polyester filter screen 8 and the ring frame 5 to rotate synchronously, so as to achieve full coverage cleaning of the entire outer circumference of the filter screen. After the lint on the filter screen surface is removed, the electric telescopic rod 15 drives the cleaned anti-stick polyester filter screen 8 to extend back to the filter slot 36, restoring the filtration and heat dissipation function. During the synchronous process of filter screen resetting, the push plate 25 inside the assembly frame 4 continuously pushes the Teflon scraper 10 to move axially along the roller surface. During the movement, the Teflon scraper 10 simultaneously scrapes off the lint and residual sticky particles adhering to the surface of the rigid roller 9. Under the continuous pushing action, the lint gradually gathers and rolls up to form an annular lint ring. Thanks to the low surface energy characteristics of Teflon material, the sticky particles are not easy to adhere to the scraper surface, ensuring the continuous effectiveness of the scraping operation. During the entire heat dissipation operation, part of the hot air discharged from the temperature control fan unit 11 is introduced into the hollow cavity of the rigid roller 9 through the diversion duct 12, and then through the return duct. 13. The return flow is discharged, and the residual heat of the heat dissipation is used to maintain the surface temperature of the rigid roller 9 within a suitable range, so as to avoid the sticky particles from solidifying and failing due to the low ambient temperature. At the same time, the suitable temperature range can cooperate with the scraping operation of the Teflon scraper 10 to avoid the solidified sticky particles from hindering the axial movement of the Teflon scraper 10. When the anti-stick polyester filter screen 8 is completely reset to the filter slot 36 position, the annular flying fluff ring is also pushed by the Teflon scraper 10 to the corresponding position of the vertical blade 27. Then, the end motor 28 drives the shaft 29 and the scraping crank 30 to rotate. The rotating scraping crank 30 pulls the annular flying fluff ring, and with the cutting action of the vertical blade 27, the annular flying fluff ring breaks and falls off, finally falling into the collection slot of the end collection box 3, completing the single-cycle flying fluff cleaning and collection operation. This invention effectively addresses the adverse effects of high pollen density on the heat dissipation and operation of electricity metering boxes. During periods of concentrated pollen outbreaks, the accessory box 2 is fixedly installed at the bottom of the metering box body 1, allowing the corresponding pipes inside the metering box body 1 to be compatible and connected with the accessory box 2. This enables functional expansion without altering the original structure of the metering box, offering excellent installation convenience and equipment compatibility. After being put into operation, it can clean and collect the pollen adhering to the surface of the anti-stick polyester filter screen 8 at preset intervals, continuously ensuring the unobstructed airflow of the heat dissipation channel and reducing the airflow resistance and heat exchange efficiency reduction caused by pollen accumulation. This addresses the issue of insufficient airflow forcing the cooling fan to operate at high speed continuously, reducing additional energy consumption and equipment wear and tear, and ensuring the stable maintenance of the metering box's original automatic temperature control energy-saving effect. After the period of excessive fluff dispersal ends, accessory box 2 can be completely unloaded from the main body 1 of the metering box, and the fluff collected inside can be cleaned in a unified manner. This reduces the difficulty and maintenance cost of decentralized manual cleaning, and does not interfere with the normal operation of the metering box during non-fluff periods, effectively improving the operational stability and overall energy-saving benefits of the outdoor energy-saving metering box in environments with high fluff dispersal.
