Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and in particular to a distribution box with a self-cleaning function. Background Technology

[0002] As the core equipment for power distribution and control, distribution boxes are widely used in industrial, commercial, and residential places.

[0003] The existing distribution boxes have the following technical problems: Dust accumulation problem: After long-term operation, dust, catkins, oil stains and other impurities in the air will adhere to the surface of components, heat sink fins and filters, affecting heat dissipation efficiency. In severe cases, it can lead to overheating damage or short circuit failure of components. Moreover, the current technology generally requires the filter to be removed for cleaning, which is very troublesome and not timely. If it is necessary to clean the electrical components inside the distribution box, the distribution box must be shut down for cleaning, which will have an adverse effect on the operation of the distribution box.

[0004] High maintenance costs: The cleaning and maintenance of existing distribution boxes mainly rely on manual periodic inspections and cleaning. For distribution boxes installed in remote areas, high places or harsh environments, manual maintenance is difficult, costly and time-consuming. Therefore, it is necessary to develop a distribution box that can automatically complete internal cleaning, reduce the frequency of manual maintenance and improve the convenience of maintenance, so as to improve the operational stability of the distribution box and reduce maintenance costs. Summary of the Invention

[0005] To improve the stability of the distribution box during operation and reduce maintenance costs, this application provides a distribution box with a self-cleaning function, which can automatically complete internal cleaning, reduce the frequency of manual maintenance, and improve the convenience of maintenance.

[0006] This application provides a self-cleaning electrical distribution box, which adopts the following technical solution: A self-cleaning distribution box includes a box body and a self-cleaning device installed on the box body, wherein the self-cleaning device includes: A partition plate is installed on the box body and is in a vertical position; the partition plate divides the box body into an inlet chamber and a meter chamber, and has an air inlet hole that communicates with the bottom of the meter chamber, and an air inlet hole that communicates with the top of the inlet chamber on the box body; The air outlet is located on the air inlet. The gas outlet mechanism is connected to the top of the meter room and is used to output gas while preventing rainwater from entering. A pre-separation mechanism is installed on the housing. Outside air passes through the pre-separation mechanism to remove impurities and moisture, and then enters the inlet chamber through the air inlet. An electrostatic adsorption mechanism is installed at the bottom of the meter compartment, forming an electrostatic adsorption area for adsorbing impurities, and is connected to the air inlet. The filter plate slides vertically on top of the electrostatic adsorption mechanism via an elastic mechanism, and is in a horizontal state with multiple filter holes evenly distributed. The collection mechanism is located below the electrostatic adsorption mechanism and is used to collect impurities falling downwards. The pulse cleaning mechanism is located at the top of the meter compartment and is used to blow air downwards; When the air outlet is activated, the air in the inlet chamber moves to the electrostatic adsorption area where it is adsorbed and impurities are removed. The air then rises, passes through the filter plate, and enters the meter chamber to dissipate heat from the electrical components. Finally, it is output through the air outlet mechanism. When the electrostatic adsorption mechanism is de-energized, the adsorbed impurities fall downwards under gravity into the collection mechanism for collection. When the air outlet is paused, the pulse cleaning mechanism blows air downwards to clean impurities on the electrical components and the filter plate.

[0007] By adopting the above technical solution, the box is divided into an inlet compartment and a meter compartment by a partition plate. Electrical components that are sensitive to moisture and impurities are installed in the meter compartment. The inlet compartment is used to connect with external cables. Then, the inlet compartment and the meter compartment are connected by copper busbars to transmit power.

[0008] When the air outlet is activated, outside air first passes through a pre-separation mechanism to remove impurities and moisture. The air is then transported downwards from the top of the inlet chamber to cool the inlet chamber. The air then moves through the air inlet to the electrostatic adsorption mechanism, where an electrostatic field is generated by energizing the mechanism, causing impurities in the air to be adsorbed onto it. The air then rises through a filter plate for filtration. The filtered air then rises through electrical components located in the meter room for heat dissipation and cooling. Finally, the air is output through the air outlet mechanism.

[0009] Impurities adsorbed on the electrostatic adsorption mechanism clump together. The electrostatic adsorption mechanism is de-energized periodically, causing the adsorbed clumps of impurities to fall downwards under gravity into the collection mechanism for collection. Moreover, when the impurities are electrostatically adsorbed, they are located on the side wall of the electrostatic adsorption mechanism, so that when the impurities fall downwards under gravity, the upward-moving air has little impact on the impurities. Then, the electrostatic adsorption mechanism continues to be energized to adsorb impurities in the air.

[0010] As impurities accumulate on the filter plate, the clogged filter holes gradually enlarge, reducing the airflow path and increasing the upward thrust of the air on the filter plate. This upward movement causes some impurities to fall off the filter plate. Once the filter plate has moved a designated distance, the air outlet stops, and the filter plate moves downward under gravity. Simultaneously, the pulse cleaning mechanism activates, blowing air downwards. The air passes through the filter plate for cleaning, and the fallen impurities are adsorbed by the electrostatic adsorption mechanism. Some impurities fall directly downwards into the collection mechanism for collection.

[0011] When blowing air downwards, it can also clean the dust on the electrical components in the meter room. These impurities usually enter through the filter holes, so after blowing air, these impurities can also be adsorbed and removed by the electrostatic adsorption mechanism after passing through the filter holes. After cleaning is completed, the pulse cleaning mechanism is turned off and the air outlet is turned on to continue to remove impurities and dissipate heat. The staff can clean the collection mechanism regularly, without the need to clean the filter plate and the inside of the box.

[0012] The enclosure is divided into zones by partitions, which enhances its safety and allows electrical components that generate a lot of heat or are susceptible to moisture to be placed in the meter room for individual processing, resulting in faster and better handling.

[0013] The pre-separation mechanism removes impurities and moisture from the air. The air then moves downward to cool the inlet chamber, and the impurities fall to the bottom of the chamber under the influence of gravity and air pressure. At this point, the number of impurities is small. The air is then filtered through an electrostatic adsorption mechanism and a filter plate before cooling the meter chamber, thus greatly improving heat dissipation.

[0014] When the electrostatic adsorption mechanism is de-energized, the adsorbed impurities fall downwards into the collection mechanism under gravity for collection. After a period of power de-energization, the electrostatic adsorption mechanism is re-energized to adsorb impurities, and this process is repeated. Simultaneously, when impurities clog the filter plate and are moved, the air outlet stops, and the pulse cleaning mechanism starts blowing downwards to clean it. This process cleans the filter plate and impurities located in the meter room. The electrostatic adsorption mechanism and the collection mechanism continue to work together to collect impurities. After cleaning is completed, the pulse cleaning mechanism stops, and the air outlet restarts to dissipate heat, thus achieving automatic cleaning. Staff only need to clean the collection mechanism, making maintenance convenient and stable, thereby improving the stability of the distribution box during operation and reducing maintenance costs.

[0015] Optionally, the electrostatic adsorption mechanism includes: The adsorption tube is installed at the bottom of the meter compartment, with its top connected to the filter plate and its bottom connected to the collection mechanism. Multiple adsorption plates are spaced apart inside the adsorption tube. The electrostatic adsorption zone is formed by the cooperation of multiple adsorption plates and is used to adsorb and remove impurities. The connecting pipe connects to the air outlet and the adsorption pipe.

[0016] By adopting the above technical solution, the air outlet is activated, allowing air to enter the adsorption tube through the connecting pipe. The air then passes through the electrostatic adsorption area formed by multiple adsorption plates, where impurities are adsorbed onto the adsorption plates to remove impurities from the air. The air then rises and passes through the filter plate, where the impurities adsorbed on the adsorption plates clump together. After the adsorption plates are de-energized, the clumps of impurities fall downwards under gravity into the collection mechanism for collection, thereby removing impurities from the air.

[0017] Optionally, the resilient mechanism includes: An installation ring is positioned at the top of the adsorption tube and communicates with the inside of the adsorption tube; the filter plate now slides within the installation ring. The elastic element is disposed on the lower surface of the adsorption tube and the filter plate; The air blowing assembly is connected to the connecting pipe. In the initial state, the air blowing assembly is in a blocked state. The filter plate is opened after it moves up and blows air towards the lower surface of the filter plate for cleaning.

[0018] By adopting the above technical solution, the filter plate is slidably installed on the inner side wall of the mounting ring, and the elastic element is pressed against the filter plate for positioning. Air is filtered through multiple filter holes. As the number of filter holes that are blocked increases, the air thrust on the filter plate increases, thereby pushing the filter plate upward. After the filter plate moves upward, the air blowing component is opened, and the air blowing component blows air towards the lower surface of the filter plate to clean it, thereby cleaning the impurities on the filter plate and unblocking the filter holes. This reduces the air thrust on the filter plate, and the filter plate moves downward under the action of gravity and the elastic force of the elastic element.

[0019] Optionally, the blowing assembly includes: An air blowing pipe is installed on the connecting pipe and forms an air blowing hole that communicates with the mounting ring. A baffle is installed on the filter plate. In the initial state, the baffle blocks the air blowing hole. The filter plate moves up, driving the baffle to move up, so that the air in the connecting pipe is blown through the air blowing hole onto the lower surface of the filter plate, and is used to clean the impurities on the lower surface of the filter plate.

[0020] By adopting the above technical solution, in the initial state, the baffle blocks the air blowing pipe, and the air outlet is activated, so that air enters the adsorption pipe through the connecting pipe. As more filter holes are blocked, the filter plate moves up, driving the baffle plate to move up. The baffle plate opens the air blowing hole. Moreover, after some filter holes are blocked, the space for air to pass through is also reduced, so that some air is blown onto the lower surface of the filter plate through the air blowing hole, thereby cleaning the filter plate, improving the cleaning effect of the filter plate, improving the stability of the power distribution box during operation, and reducing maintenance costs.

[0021] Optionally, the mounting ring is provided with a mounting base, the filter plate is provided with a guide rod that slides through the mounting base, and the elastic element is sleeved on the guide rod and presses against the mounting base and the filter plate for positioning.

[0022] By adopting the above technical solution, the movement of the filter plate is guided, and when the filter plate is removed, the guide rod is removed from the mounting base, and then the elastic element can be replaced. After the replacement is completed, the filter plate is slidably installed on the mounting ring, and the guide rod is slidably inserted into the mounting base. The elastic element presses against the mounting base and the filter plate for positioning, which further improves the stability of the filter plate during operation, improves the stability of the distribution box during operation, and reduces maintenance costs.

[0023] Optionally, the pulse cleaning mechanism includes: A jet plate is rotatably mounted on the meter compartment and has multiple jet holes evenly distributed on it. In the initial state, the jet plate is vertical. When jetting is required, the jet plate rotates to a horizontal state and the jet holes face downwards. Drive components, used to drive the jet plate to rotate; The trachea connects to the jet nozzle and air source; A control valve is used to control the opening and closing of the airway.

[0024] By adopting the above technical solution, when cleaning is required, the driving component activates the jet plate to rotate, causing the jet plate to turn to a horizontal state with multiple jet holes facing downwards. The control valve controls the air pipe to open, and gas is sprayed downwards through the multiple jet holes for cleaning. After cleaning, the driving component drives the jet plate to rotate back, and the control valve controls the air pipe to close, thereby achieving a larger cleaning range. After cleaning, the air input dissipates heat from the meter chamber, reducing the obstruction effect of the jet plate on the air, allowing the dissipated air to be quickly output through the air outlet mechanism, while improving the cleaning effect of impurities and the heat dissipation effect.

[0025] Optionally, the jet plate includes a plate body one and a plate body two, and the jet holes are opened on the plate body one and the plate body two. The plate body one is rotatably mounted on the meter chamber, and the plate body two is slidably mounted on the plate body one. The driving component is a telescopic rod and is rotatably mounted on the meter chamber and the plate body two. When jetting is required, the driving component drives the plate body two and the plate body one to rotate and the plate body two moves away from the plate body one.

[0026] By adopting the above technical solution, when cleaning is required, the piston rod of the driving component extends to drive plate two to slide and rotate with plate one, so that plate two and plate one rotate to a horizontal state, and plate two rotates away from plate one. Plate two and plate one can cooperate to form a larger air outlet area, which improves the cleaning effect of impurities.

[0027] After cleaning, the piston rod of the drive component shortens and drives the second plate to move back and rotate, so that the second plate and the first plate rotate to the side of the air flow path in the meter room, and the second plate is located closer to the first plate. This can greatly reduce the volume of the jet plate, thereby improving the cleaning effect of impurities, and also reducing the volume occupied by the jet plate when it is stored.

[0028] Optionally, the collection mechanism includes: The collection box is located at the bottom of the box and is connected to the bottom of the meter compartment, and has an installation hole. The collection frame is slidably mounted on the mounting hole and is used to collect fallen impurities. It is equipped with a mounting plate that rests against the collection box for positioning.

[0029] By adopting the above technical solution, the collection mechanism is a drawer-type structure. Impurities fall downwards into the collection box for collection. When cleaning is required, the collection box is pulled down for cleaning. After cleaning, it is slid into the mounting hole and the mounting plate is pushed against the collection box for positioning, which improves the stability of the distribution box during operation and reduces maintenance costs.

[0030] Optionally, the air outlet mechanism includes: The vent pipe is located at the top of the box and connects to the top of the meter room, and has multiple downward-sloping vent holes. The roof is installed on the vent pipe and is angled downwards.

[0031] By adopting the above technical solution, the air moves upward and comes into contact with the roof. Then, the air moves downward and is output through multiple air outlets, thereby achieving air output and preventing moisture from entering.

[0032] Optionally, the pre-separation mechanism includes: Cyclone separator; The air supply pipe connects the cyclone separator and the top of the inlet chamber, allowing the air processed by the cyclone separator to enter the top of the inlet chamber.

[0033] By adopting the above technical solution, the cyclone separator starts to remove moisture and impurities from the air, and then the air is input into the top of the inlet chamber through the air supply pipe, thereby realizing the input of air after removing moisture and impurities.

[0034] In summary, this application includes at least one of the following beneficial technical effects: 1. The pre-separation mechanism removes impurities and moisture from the air. The air moves downward to cool the inlet chamber, and the impurities fall to the bottom of the box under the action of gravity and air. At this time, the number of impurities is small. Then, the air is filtered by the electrostatic adsorption mechanism and the filter plate, and then the meter chamber is cooled, which greatly improves the heat dissipation effect.

[0035] 2. By de-energizing the electrostatic adsorption mechanism, the adsorbed impurities fall downwards into the collection mechanism under gravity for collection. The electrostatic adsorption mechanism continues to be energized to adsorb impurities. Simultaneously, when impurities clog the filter plate and are pushed to move, the air outlet stops, and the pulse cleaning mechanism starts blowing downwards to clean it. This can clean the filter plate and impurities located in the meter room. The electrostatic adsorption mechanism and the collection mechanism continue to work together to collect impurities. After cleaning is completed, the pulse cleaning mechanism stops, and the air outlet restarts to dissipate heat. This achieves automatic cleaning, and the staff only needs to clean the collection mechanism, making maintenance convenient and stable. This improves the stability of the distribution box during operation and reduces maintenance costs.

[0036] 3. When cleaning is required, the piston rod of the drive component extends to drive plate two to slide and rotate with plate one, so that plate two and plate one rotate to a horizontal state, and plate two rotates away from plate one. Plate two and plate one can cooperate to form a larger air outlet area, which improves the cleaning effect of impurities.

[0037] 4. After cleaning, the piston rod of the drive component shortens and drives the second plate to move back and rotate, so that the second plate and the first plate rotate to the side of the air flow path in the meter room, and the second plate is located closer to the first plate. This can greatly reduce the volume of the jet plate, thereby improving the cleaning effect of impurities, and also reducing the volume occupied by the jet plate when it is stored.

[0040] The following provides a further detailed description of this application.

[0041] This application discloses a distribution box with a self-cleaning function.

[0042] Reference Figures 1-2 The distribution box with self-cleaning function includes a box body 1 and a self-cleaning device 2 installed on the box body 1. The self-cleaning device 2 is used to automatically clean the dust inside the box body 1. The staff only needs to clean the impurities that have been collected periodically.

[0043] Reference Figures 1-4The self-cleaning device 2 includes a partition plate 21, an air outlet 22, an air outlet mechanism 3, a pre-separation mechanism 4, an electrostatic adsorption mechanism 5, a filter plate 23, a collection mechanism 6, and a pulse cleaning mechanism 9. The partition plate 21 is fixedly installed on the inner side wall of the housing 1 and is in a vertical state, dividing the housing 1 into an independent inlet chamber 11 and a meter chamber 12. The top of the partition plate 21 is fixedly installed with copper busbars at both ends extending into the inlet chamber 11 and the meter chamber 12, respectively. The copper busbars are used for the transmission of electrical energy in the inlet chamber 11 and the meter chamber 12. The bottom of the partition plate 21 is provided with an air inlet hole 14, which is connected to the bottom of the meter chamber 12. An air inlet hole 15 is provided on the outer side wall of the housing 1 and is connected to the top of the inlet chamber 11. The air outlet 22 is a fan, which is fixedly installed on the air inlet hole 14 and the air outlet faces the meter chamber 12, so that the air in the inlet chamber 11 enters the meter chamber 12.

[0044] The pre-separation mechanism 4 is installed on the housing 1, and allows outside air to pass through the pre-separation mechanism 4 to remove impurities and moisture before entering the inlet chamber 11 through the air inlet 15. The pre-separation mechanism 4 includes a cyclone separator 41 and an air supply pipe 42. The cyclone separator 41 is fixedly installed on the ground or on the housing 1, and the air supply pipe 42 is fixedly installed on the cyclone separator 41 and communicates with the air inlet 15.

[0045] The electrostatic adsorption mechanism 5 is located at the bottom of the meter chamber 12 and forms an electrostatic adsorption area 54 for adsorbing impurities, and is connected to the air inlet 14; the filter plate 23 slides vertically on top of the electrostatic adsorption mechanism 5 through the elastic mechanism 7 and is in a horizontal state, and has multiple filter holes evenly distributed; the collection mechanism 6 is located below the electrostatic adsorption mechanism 5 and is used to collect impurities falling downwards; the pulse cleaning mechanism 9 is located at the top of the meter chamber 12 and is used to blow air downwards; the air outlet mechanism 3 is connected to the top of the meter chamber 12 and is used to output gas and prevent rainwater from entering.

[0046] When the air outlet 22 is activated, outside air is drawn into the cyclone separator 41 to remove impurities and moisture. Then, the air enters the top of the inlet chamber 11 and descends to cool the inlet chamber 11. If impurities are still present in the air, they will settle to the bottom wall of the housing 1 under gravity. At this point, the number of impurities is relatively small. Then, the air enters the bottom of the meter chamber 12. The air passes through the electrostatic adsorption area 54, where the electrostatic adsorption mechanism 5 is energized to adsorb and remove impurities in the air. The air then passes through the filter plate 23 and enters the meter chamber 12 to cool and dissipate heat from the electrical components located in the meter chamber 12. Finally, the air is output through the air outlet mechanism 3.

[0047] After impurities are adsorbed onto the electrostatic adsorption mechanism 5, they aggregate together. After a period of time, the electrostatic adsorption mechanism 5 is de-energized, and the aggregated impurities fall downwards into the collection mechanism 6 under the action of gravity for collection. The impurities on the filter plate 23 gradually increase, that is, the number of blocked filter holes gradually increases, reducing the space for air to pass through, thereby increasing the upward pushing force on the filter plate 23, causing the filter plate 23 to move upwards. The movement of the filter plate 23 will also cause some of the adsorbed impurities to fall off.

[0048] After the pulse cleaning mechanism 9 senses that the filter plate 23 has moved up a specified distance, the air outlet 22 closes, and the pulse cleaning mechanism 9 starts blowing air downwards, causing the impurities clogging the filter holes to fall downwards. Some impurities are adsorbed and removed by the electrostatic adsorption mechanism 5, while some impurities fall directly downwards into the collection mechanism 6 for collection under the action of gravity. At the same time, impurities that enter through the filter holes and remain on the electrical components can also be removed after passing through multiple filter holes. Meanwhile, the pulse cleaning mechanism 9 also starts to clean the impurities at regular intervals. The cleaning process is the same, and the staff only needs to clean the collection mechanism 6, which improves the stability of the distribution box during operation and reduces maintenance costs.

[0049] The venting mechanism 3 includes a vent pipe 31 and a roof 32. The vent pipe 31 is fixedly installed on the upper surface of the housing 1 and is vertically upward, communicating with the top of the meter compartment 12. At the same time, multiple downward-sloping vent holes 33 are spaced apart on the side wall of the vent pipe 31. The roof 32 is fixedly installed on the top of the vent pipe 31, with the middle position being the highest, and is inclined downward to both sides. The air in the meter compartment 12 moves upward and enters the vent pipe 31. After the air comes into contact with the roof 32, it is output downward through the multiple vent holes 33. The roof 32 and the multiple downward-sloping vent holes 33 can both prevent rainwater from entering.

[0050] The electrostatic adsorption mechanism 5 includes an adsorption tube 51, multiple adsorption plates 52, and a connecting pipe 53. The adsorption tube 51 is fixedly installed on the bottom wall of the box 1. The adsorption tube 51 is annular and open at both the top and bottom. The inner wall of the adsorption tube 51 is aligned with the electrical components located in the meter chamber 12. The multiple adsorption plates 52 are horizontal and are arranged in multiple groups at intervals. The two ends of the adsorption plates 52 are fixedly installed on the inner walls of the adsorption tube 51 at the ends near and away from the air outlet 22, respectively. Each group of adsorption plates 52 has two plates arranged opposite each other, and the electrostatic adsorption area 54 is formed by the cooperation of two adsorption plates 52.

[0051] The connecting pipe 53 is fixedly installed on the partition plate 21 and the adsorption pipe 51 near the partition plate 21. The air outlet 22 is located inside the connecting pipe 53. The adsorption pipe 51 near the air outlet 22 has multiple connecting holes corresponding to the electrostatic adsorption area 54 and communicating with the inside of the connecting pipe 53. When the air outlet 22 is activated, air enters multiple electrostatic adsorption areas 54 through the connecting pipe 53 and multiple connecting holes in sequence, which is used to adsorb and remove impurities in the air. The impurities are adsorbed on the opposite side walls of the two adsorption plates 52. After being adsorbed, the impurities gather together to form clumps of impurities. The clumps of impurities are easy to fall into the collection mechanism 6 for collection under the action of gravity after the adsorption plates 52 are de-energized.

[0052] The collection mechanism 6 includes a collection box 61 and a collection frame 62. The collection box 61 is located at the bottom of the housing 1 and is connected to the bottom of the adsorption tube 51. An installation hole is provided on the outer wall of the collection box 61. The collection frame 62 is horizontally slidably installed on the installation hole. Impurities falling from the adsorption tube 51 and the adsorption plate 52 are moved into the collection frame 62 for collection. An installation plate is fixedly installed on the collection frame 62 against the outer wall of the collection box 61 for positioning. The operator can pull the installation plate to remove the collection frame 62 to clean the impurities. After cleaning, the collection frame 62 is horizontally slidably installed on the installation hole, and the installation plate is positioned against the installation box, thereby cleaning the collected impurities.

[0053] The elastic mechanism 7 includes a mounting ring 71, elastic elements 72, and an air blowing assembly 8. The mounting ring 71 is fixedly mounted on the top of the adsorption tube 51, and the projections of the inner sidewalls of the adsorption tube 51 and the mounting ring 71 in the vertical direction coincide. Horizontal mounting seats 73 are fixedly mounted at the bottom of the inner sidewalls at both ends of the mounting ring 71. The filter plate 23 is vertically slidably mounted on the inner sidewall of the mounting ring 71, and its outer sidewall is adapted to the inner sidewall of the mounting ring 71. Two vertical guide rods 74 are fixedly mounted at intervals on the lower surface of the filter plate 23, and the two guide rods 74 slide vertically through the two mounting seats 73 respectively. Two elastic elements 72 are provided at intervals, and the two elastic elements 72 are respectively sleeved on the two guide rods 74, with their ends pressing against the filter plate 23 and the mounting seats 73.

[0054] The air blowing assembly 8 is connected to the connecting pipe 53. In the initial state, the air blowing assembly 8 is in a blocked state. After the filter plate 23 moves upward, it is opened and air is blown towards the lower surface of the filter plate 23 for cleaning. The air blowing assembly 8 includes an air blowing pipe 81 and a baffle 82. The air blowing pipe 81 is fixedly installed on the upper surface of the connecting pipe 53 and is fixedly connected to the outer wall of the mounting ring 71, forming a flat air blowing hole 83 inside the mounting ring 71. The baffle 82 is fixedly installed on the upper surface of the filter plate 23.

[0055] Initially, the air blowing hole 83 is located above the filter plate 23, and the baffle 82 abuts against the inner wall of the mounting ring 71, sealing the air blowing hole 83. When the filter holes on the filter plate 23 are blocked, the increased air pressure pushes the filter plate 23 upward, causing the filter plate 23 and the baffle 82 to move upward, opening the air blowing hole 83. Since some filter holes are blocked, air is prevented from entering the connecting pipe 53, allowing some air in the connecting pipe 53 to be blown through the air blowing hole 83 to the lower surface of the filter plate 23, causing impurities on the lower surface of the filter plate 23 to fall off for cleaning.

[0056] Reference Figures 1-6 The pulse cleaning mechanism 9 includes a jet plate 91, a drive component 92, an air pipe, and a control valve. The jet plate 91 includes a first plate 94 and a second plate 95 that are slidably connected. The first plate 94 is rotatably mounted on the top wall of the meter chamber 12 via a rotating shaft. The rotating shaft is horizontal and its axis is parallel to the length direction of the adsorption plate 52. The second plate 95 is slidably mounted on the first plate 94, and its sliding direction is perpendicular to the axis of the rotating shaft. Multiple jet holes 96 are evenly provided on both the first plate 94 and the second plate 95. The drive component 92 is a telescopic rod. The drive component 92 is rotatably mounted on the top wall of the meter chamber 12, and its piston rod is rotatably connected to the second plate 95. The rotation directions of the drive component 92 at two points are parallel to the axis of the rotating shaft.

[0057] The air pipe is a flexible tube, which is fixedly connected to plate 94. Plate 94 and plate 95 have interconnected air chambers that are connected to multiple air jet holes 96. The air pipe is connected to the air jet chambers, thus enabling the air pipe to connect with multiple air jet holes 96 and to a gas source or gas tank to supply gas. The control valve is fixedly installed on the air pipe and is used to control the opening or closing of the air pipe. The control valve and the drive component 92 are both controlled by a control box, which is used to control the start and stop of the air outlet component 22. At the same time, a sensor is fixedly installed on the inner wall of the mounting ring 71 and above the filter plate 23. The sensor and the time relay are both electrically connected to the control valve.

[0058] When some filter holes are blocked, air pushes the filter plate 23 and baffle 82 upward, causing the air outlet 83 to open. The filter plate 23 then contacts the sensor, thereby controlling the air outlet 22 to stop. The control valve controls the air pipe to open for cleaning. After cleaning continues for a period of time, the control valve closes the air pipe, and the air outlet 22 restarts to dissipate heat. At the same time, the above cleaning process can be controlled according to time, and both the sensor and the time relay can achieve control, and finally, the control is achieved through the control box.

[0059] In the initial state, i.e., during heat dissipation, plate 2 95 slides close to plate 1 94 and is in a vertical position, thus greatly reducing the space occupied. When cleaning is required, the piston rod of the drive component 92 extends, driving plate 2 95 away from plate 1 94 and rotating downwards until plate 1 94 and plate 2 95 are in a horizontal position. Multiple air jets 96 are set downwards, and plate 2 95 is moved to the side away from plate 1 94, so that multiple air jets 96 can cover a larger area, increasing the area for heat dissipation and cleaning. After cleaning is completed, the drive component 92 retracts, causing plate 2 95 to approach plate 1 94 and rotate, causing plate 2 95 to move back, and causing plate 1 94 and plate 2 95 to rotate to a vertical position.

[0060] The working principle of this application embodiment is as follows: When the air outlet 22 is activated, outside air passes through the cyclone separator 41 to remove impurities and moisture. The air then enters the inlet chamber 11 for cooling and enters the bottom of the meter chamber 12. The air passes through the electrostatic adsorption area 54, where multiple adsorption plates 52 are energized to generate an electrostatic field to adsorb and remove impurities in the air. The air then passes through the filter plate 23 and enters the meter chamber 12 to cool and dissipate heat from the electrical components located in the meter chamber 12. Finally, the air is output through the air outlet mechanism 3.

[0061] After impurities are adsorbed onto the electrostatic adsorption mechanism 5, they aggregate. After a period of time, the electrostatic adsorption mechanism 5 is de-energized, and the aggregated impurities fall downwards into the collection mechanism 6 under the action of gravity for collection. As the impurities on the filter plate 23 gradually increase, the number of blocked filter holes gradually increases, reducing the space for air to pass through. This increases the upward thrust on the filter plate 23, causing the filter plate 23 and the baffle 82 to move upwards, opening the air blowing hole 83. Some air in the connecting pipe 53 is blown through the air blowing hole 83 to the lower surface of the filter plate 23, causing the impurities on the lower surface of the filter plate 23 to fall off, thus cleaning the impurities on the filter plate 23.

[0062] After the pulse cleaning mechanism 9 senses that the filter plate 23 has moved up a specified distance, the air outlet 22 closes, and the pulse cleaning mechanism 9 starts blowing air downwards, causing the impurities clogging the filter holes to fall downwards. Some impurities are adsorbed and removed by the electrostatic adsorption mechanism 5, while some impurities fall directly downwards into the collection mechanism 6 for collection under the action of gravity. At the same time, impurities that enter through the filter holes and remain on the electrical components can also be removed after passing through multiple filter holes. Meanwhile, the pulse cleaning mechanism 9 also starts to clean the impurities at regular intervals. The cleaning process is the same, and the staff only needs to clean the collection mechanism 6, which improves the stability of the distribution box during operation and reduces maintenance costs.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
