Description

Technical Field

[0001] The invention belongs to the technical field of ring network switch equipment, and in particular relates to a fully insulated sealed AC metal ring network switch equipment. Background Art

[0002] Metal ring network switch is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switch and fuse. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers.

[0003] When the existing environmentally friendly fully insulated and fully sealed AC metal ring network switch is dissipating heat, air with impurities often enters the interior of the box through the air inlet and damages the internal components of the box. In addition, the existing filter will accumulate a large amount of dust after long-term use, thereby reducing the filtering effect. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent announcement number CN218334988U, which can clean the dust on the dust removal plate by rotating the cleaning roller when in use. However, since the dust impurities are light in weight and the air flows in the box, the dust will be scattered in the area between the baffle and the mounting plate and it is difficult to fall into the collection mechanism below, so the dust collection effect is poor. The subsequent dust will follow the air and contact the dust removal plate again, affecting the air filtering effect. Summary of the invention

[0004] The purpose of the present invention is to provide a fully insulated sealed AC metal ring network switch device, aiming to solve the technical problem in the prior art that the dust swept from the filter component cannot be well collected, thus affecting the subsequent air filtering effect.

[0005] The present invention is implemented as follows: a fully insulated sealed AC metal ring network switch device comprises a housing, a cabinet door is hingedly connected to the side of the housing, a first vacuum pump is fixedly installed on the top of the housing, a mesh plate is fixedly installed on the bottom of the housing, and the area surrounded by the mesh plate and the bottom surface of the housing is an air inlet cavity;

[0008] Further technical solution: the first brushes are linearly distributed on the end surface of the collecting box, and the first brushes are located on the rear side of the collecting box in the rotation direction.

[0009] Further technical solution: Two groups of baffles located at both ends of the first brush are fixedly installed on the end surface of the collection box away from the rotating tube, and the baffles are in sliding contact with the first arc plate when the collection box rotates.

[0010] Further technical solution: one end of the rotating tube is rotatably connected to a connecting tube, the connecting tube is connected to the air inlet end of the third air pump, and the air outlet end of the third air pump is connected to the outside.

[0011] Further technical solution: A cleaning shaft is rotatably installed at one end of the collecting box away from the rotating tube, both ends of the cleaning shaft extend out of the collecting box and friction wheels are fixedly installed at both ends of the cleaning shaft. When the collecting box rotates, the friction wheel contacts the first arc plate and drives the cleaning shaft to rotate. A second brush is arranged on the cleaning shaft, and the second brush covers the surface of the cleaning shaft.

[0012] Further technical solution: two groups of limit plates are fixedly installed on the inner wall of the collection box, an end of the limit plate away from the rotating tube is provided with an inclined structure, a closing plate is provided in the collection box, and both sides of the closing plate are in sliding contact with the limit plate.

[0013] Further technical solution: Multiple groups of support plates are fixedly installed in the collection box, and guide rods are slidably installed on the support plates. The guide rods are distributed along the mirror direction of the rotating tube. The end of the guide rod away from the rotating tube is fixedly connected to the closing plate, and the cross-section of the closing plate is a triangle.

[0014] Further technical solution: an elastic part is fixedly installed on the support plate, the end of the elastic part away from the support plate is fixedly connected to the closing plate, a permanent magnet is fixedly installed on the end of the guide rod away from the closing plate, an electromagnet is fixedly installed in the inner tube, and when the electromagnet is energized, its magnetic pole is the same as the end close to the permanent magnet.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the collection box rotates in the area of ​​the first curved plate, the first brush will contact the first curved plate and the filter, so that the filter is cleaned by the first brush, and the baffles on both sides reduce the number of impurities flying away from the collection box from both sides. Since the third vacuum pump draws the air in the rotating tube and discharges it to the outside, the air will enter the collection box from the opening of the collection box, and the impurities swept off the filter are accelerated by the air so that they can enter the collection box. The impurities follow the air into the rotating tube and are then extracted by the third vacuum pump, thereby completing the cleaning and collection of impurities on the filter, avoiding the dust swept off the filter from flying in the air intake chamber, reducing the probability of subsequent impurities adhering to the filter again, and ensuring that the air stably enters the shell for cooling.

[0017] 2. When the rotating tube drives the collection box to rotate and the friction wheel contacts the first arc plate, the cleaning shaft rotates under the action of friction force. When the cleaning shaft rotates, the second brush cleans the surface of the filter screen, and the rotation direction of the cleaning shaft is opposite to that of the rotating tube, so that the second brush can sweep the cleaned impurities into the collection box. At the same time, when the second brush rotates, it can push the first brush to sweep the impurities moving to the front side downward, further reducing the probability of impurities floating to the outside and increasing the probability of impurities being collected.

[0018] 3. When the collecting box rotates out of the area where the filter is located, the closing plate is reset under the action of the elastic member to close the end of the collecting box away from the rotating tube, so as to prevent the impurities inside from being thrown downward when the collecting box opening is facing downward, thereby further reducing the probability of impurities flying into the air intake chamber, improving the collection effect of impurities, and preventing the cleaned impurities from adhering to the filter again and causing blockage. When the closing plate releases the seal on this group of collecting boxes, the other groups of collecting boxes are in a closed state. Since the third vacuum pump draws air from the rotating tube, it will enter the collecting box from the opening of the collecting box, thereby increasing the speed at which air enters the collecting box. Driven by the air, the impurities will be accelerated to enter the collecting box, thereby further reducing the probability of impurities flying to the outside and improving the collection effect of impurities.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1-Figure 8 As shown, a fully insulated sealed AC metal ring network switch device provided by the present invention comprises a housing 1, a cabinet door 2 is hingedly connected to the side of the housing 1, a first air pump 4 is fixedly installed on the top of the housing 1, a mesh plate 3 is fixedly installed on the bottom of the housing 1, and the area enclosed by the mesh plate 3 and the bottom surface of the housing 1 is an air inlet cavity 30;

[0031] A bottom plate 5 is fixedly installed in the air inlet cavity 30, a first curved plate 6 is fixedly installed on the bottom plate 5, a filter screen 7 is fixedly installed on the first curved plate 6, a second curved plate 8 is fixedly installed in the air inlet cavity 30, a second air pump 9 is fixedly installed on the bottom plate 5, and the second air pump 9 is connected to a cavity surrounded by the second curved plate 8, the first curved plate 6, the bottom plate 5, and the side wall of the housing 1;

[0032] A rotating tube 10 is rotatably installed in the air inlet chamber 30. The rotating tube 10 is coaxially arranged with the first arc plate 6. The rotating tube 10 is connected to multiple groups of evenly spaced collecting boxes 17. A first brush 18 is arranged on the end surface of the collecting box 17 away from the rotating tube 10. The first brush 18 is located on the end surface of the collecting box 17 and is linearly distributed. The first brush 18 is located on the rear side of the rotating direction of the collecting box 17. Two groups of baffles 19 located at both ends of the first brush 18 are fixedly installed on the end surface of the collecting box 17 away from the rotating tube 10. When the collecting box 17 rotates, the baffles 19 are in sliding contact with the first arc plate 6. There is a coaxially arranged inner tube 11, which is fixedly connected to the rotating tube 10 through multiple groups of partitions 12. The multiple areas divided by the partitions 12 correspond to the positions of the collecting boxes 17 respectively. A rotating power part 13 for driving the rotating tube 10 to rotate is fixedly installed in the air inlet chamber 30. The rotating power part 13 drives the rotating tube 10 to rotate through a gear set 14. A third air pump 16 for extracting impurities in the rotating tube 10 is fixedly installed in the air inlet chamber 30. One end of the rotating tube 10 is rotatably connected to a connecting tube 15. The connecting tube 15 is connected to the air inlet end of the third air pump 16, and the air outlet end of the third air pump 16 is connected to the outside.

[0033] In actual application of this embodiment, the second air pump 9 draws the air in the cavity surrounded by the second curved plate 8, the first curved plate 6, the bottom plate 5, and the side wall of the shell 1 to flow upward, so that the gas in the air inlet chamber 30 can pass through the filter screen 7 upward for filtration, and at the same time, the rotating power member 13 drives the rotating tube 10 to rotate through the gear set 14, and the rotating tube 10 drives the collecting box 17 to rotate synchronously, and at the same time, the third air pump 16 draws the air in the rotating tube 10 to be discharged to the outside, and when the collecting box 17 rotates in the area of ​​the first curved plate 6, the first brush 18 will contact the first curved plate 6 and the filter screen 7, so that the filter screen 7 is cleaned by the first brush 18, and the impurities are reduced from the two baffles 19 on both sides. The number of impurities flying sideways from the collection box 17 is determined by the third vacuum pump 16, which extracts the air in the rotating tube 10 and discharges it to the outside, so that the air enters the collection box 17 from the opening of the collection box 17, and is accelerated by the air so that the impurities swept off the filter 7 can enter the collection box 17. The impurities follow the air into the rotating tube 10 and are then extracted by the third vacuum pump 16, thereby completing the cleaning and collection of the impurities on the filter 7, avoiding the dust swept off the filter 7 from flying in the air intake chamber 30, reducing the probability of subsequent impurities adhering to the filter 7 again, ensuring that the air stably enters the shell 1 for cooling, and at the same time, the hot air at the top of the shell 1 is extracted by the first vacuum pump 4 to complete the exhaust.

[0034] In an example of the present embodiment, the rotating power part 13 is a motor, and of course it can also be other parts that can output rotational power, such as a hydraulic motor. The motor drives the rotating tube 10 to rotate, and the gear set 14 is a bevel gear set. The two sets of bevel gears are respectively fixedly mounted on the rotating tube 10 and the motor. The motor drives the rotating tube 10 to rotate through the bevel gear set.

[0035] like Figure 3-Figure 8 As shown, a fully insulated sealed AC metal ring network switch device provided by the present invention, a cleaning shaft 20 is rotatably installed at one end of the collecting box 17 away from the rotating tube 10, both ends of the cleaning shaft 20 extend out of the collecting box 17 and both ends of the cleaning shaft 20 are fixedly installed with friction wheels 22, when the collecting box 17 rotates, the friction wheel 22 contacts the first arc plate 6 and drives the cleaning shaft 20 to rotate, a second brush 21 is arranged on the cleaning shaft 20, and the second brush 21 covers the surface of the cleaning shaft 20.

[0036] In actual application of this embodiment, when the rotating tube 10 drives the collecting box 17 to rotate and the friction wheel 22 contacts the first arc plate 6, the cleaning shaft 20 is rotated under the action of friction force. When the cleaning shaft 20 rotates, the second brush 21 cleans the surface of the filter 7, and the rotation direction of the cleaning shaft 20 is opposite to the rotation direction of the rotating tube 10, so that the second brush 21 can sweep the cleaned impurities into the collecting box 17. At the same time, when the second brush 21 rotates, it can push the first brush 18 to sweep the impurities moving to the front side downward, further reducing the probability of impurities floating to the outside and improving the probability of impurities being collected.

[0037] like Figure 3-Figure 8 As shown, a fully insulated sealed AC metal ring network switch device provided by the present invention, two sets of limit plates 27 are fixedly installed on the inner wall of the collection box 17, and an inclined structure is provided at one end of the limit plate 27 away from the rotating tube 10. A closing plate 26 is provided in the collection box 17, and both sides of the closing plate 26 are in sliding contact with the limit plate 27.

[0038] Specifically, a plurality of support plates 23 are fixedly installed in the collection box 17, guide rods 24 are slidably installed on the support plates 23, and the guide rods 24 are distributed along the mirror direction of the rotating tube 10. One end of the guide rods 24 away from the rotating tube 10 is fixedly connected to the closing plate 26, and the cross-section of the closing plate 26 is a triangle.

[0039] Specifically, an elastic member 25 is fixedly mounted on the support plate 23, and one end of the elastic member 25 away from the support plate 23 is fixedly connected to the closing plate 26. A permanent magnet 28 is fixedly mounted on one end of the guide rod 24 away from the closing plate 26. An electromagnet 29 is fixedly mounted in the inner tube 11. When the electromagnet 29 is energized, its magnetic pole is the same as that of the end close to the permanent magnet 28.

[0040] In actual application of this embodiment, the electromagnet 29 is energized. When the collection box 17 rotates to one side of the filter screen 7, the permanent magnet 28 enters the area covered by the electromagnet 29. After the electromagnet 29 is energized, the magnetic pole is the same as the end of the permanent magnet 28 that is close to it. Under the action of the magnetic force, the guide rod 24 moves away from the rotating tube 10 and stretches the elastic member 25, and then the closing plate 26 moves away from the rotating tube 10 and separates from the limiting plate 27. At this time, the end of the collection box 17 away from the rotating tube 10 is no longer closed, and then the impurities cleaned on the filter screen 7 can enter the collection box 17 and descend.

[0041] When the collecting box 17 rotates to the other side of the filter 7, the permanent magnet 28 is out of the area covered by the electromagnet 29. At this time, under the action of the elastic member 25, the closing plate 26 is reset to close the collecting box 17 away from one end of the rotating tube 10, so as to prevent the impurities inside from being thrown downward when the collecting box 17 is opened downward, thereby further reducing the probability of impurities flying into the air inlet chamber 30, improving the collection effect of impurities, and preventing the cleaned impurities from adhering to the filter 7 again to cause blockage. When the closing plate 26 releases the closure of this group of collecting boxes 17, the other groups of collecting boxes 17 are in a closed state. Since the third vacuum pump 16 draws air from the rotating tube 10, it will enter the collecting box 17 from the opening of the collecting box 17, thereby increasing the speed at which air enters the collecting box 17. Driven by the air, the impurities will be accelerated to enter the collecting box 17, thereby further reducing the probability of impurities flying to the outside and improving the collection effect of impurities.

[0042] In an embodiment of the present invention, the elastic member 25 is a spring, and can also be other elastic members such as an elastic ball, and the spring applies a resetting pulling force to the closing plate 26 .

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
