DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution for a ring main unit with a built-in dehumidification component:

[0027] Embodiment 1:

[0028] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a ring network cabinet with a built-in dehumidification component includes a ring network cabinet body 1, a cabinet door 2 is hinged on the front of the ring network cabinet body 1, a control panel is arranged on the cabinet door 2, and a moisture-proof base 30 is fixedly installed at the bottom end of the ring network cabinet body 1, and the moisture-proof base 30 prevents moisture from underground from entering the interior of the ring network cabinet body 1;

[0029] The dehumidification components are placed on both sides of the ring network cabinet 1, and the dehumidification components include two top boxes 10 and two arc covers 9. The two top boxes 10 and the arc covers 9 are fixedly installed on the inner walls on both sides of the ring network cabinet 1. The tops of the two top boxes 10 are fixedly provided with covers 11. The interiors of the two top boxes 10 are filled with desiccant particles 31. The desiccant particles 31 absorb the moisture inside the ring network cabinet 1 to achieve the purpose of dehumidification.

[0030] The bottom ends of the two top boxes 10 are fixed with oblique boxes 29, which play a buffering role to prevent the desiccant particles 31 inside the top box 10 from flowing into the interior of the arc cover 9 at one time under the action of gravity. The bottom ends of the two oblique boxes 29 are connected to one end of the corresponding arc cover 9. The interiors of the two arc covers 9 are both provided with oblique net cylinders 12, which play a guiding role. Since the arc cover 9 is set to be arc-shaped and has a certain degree of tortuosity, it does not completely fit with the inner wall of the ring network cabinet 1 at a certain angle, and the arrangement The oblique mesh tube 12 guides to ensure that the desiccant particles 31 flow into the interior of the arc cover 9 and do not flow out from the gap between the arc cover 9 and the inner wall of the ring network cabinet 1. The top ends of the two oblique mesh tubes 12 are connected to the bottom ends of the corresponding oblique boxes 29. The bottom ends of the two arc covers 9 are connected to the conduits 5. One end of the two conduits 5 is connected to the recovery box 7 to recover the desiccant particles 31 that have absorbed moisture and humidity to saturation. A slot 28 is opened in the middle of the top of the recovery box 7, and one end of the conduit 5 is connected to the slot 28 through an interlaced connection.

[0031] The tops of the two recycling boxes 7 are connected to the plugging plates 14 through the curved springs 15. In order to block the slots 28 and prevent the desiccant particles 31 from flowing into the interior of the recycling box 7, one end of the two curved springs 15 is fixedly connected to the bottom end of the plugging plates 14, and the other ends of the two curved springs 15 are fixedly connected to the inner wall of the recycling box 7. The two curved springs 15 support the two plugging plates 14 in the horizontal direction. One end of the two plugging plates 14 is rotatably connected to the inner wall of one side of the recycling box 7 through the rotating shaft 23. The rotating shaft 23 can ensure the opening and closing of the plugging plates 14. One side of the two plugging plates 14 is interspersed with a connecting shaft 16. The two connecting shafts The inner wall of the shaft 16 passes through the inner wall of the recovery box 7 and is fixedly connected with a pedal 13. The pedal 13 drives the blocking plate 14 to move through the connecting shaft 16 to control the desiccant particles 31 to flow into the interior of the recovery box 7. The outer walls of the two recovery boxes 7 are provided with arc grooves 22, which facilitate the movement of the connecting shaft 16. The two connecting shafts 16 are slidably connected to the corresponding arc grooves 22. The interiors of the two recovery boxes 7 are filled with saturated desiccant 8, which is the desiccant particles 31 that adsorb moisture and humidity to saturation. The fronts of the two recovery boxes 7 are movably provided with baffles 24, which facilitate timely cleaning of the interior of the recovery box 7.

[0032] In specific use, the ring network cabinet with a built-in dehumidification component of the present invention, when dehumidifying the interior of the ring network cabinet body 1, open the cover 11 to pour the desiccant particles 31 into the interior of the top box 10, and then the desiccant particles 31 flow into the interior of the inclined box 29, and then slowly fall along the inner wall of the ring network cabinet body 1 along the arc cover 9 to dehumidify the interior of the ring network cabinet body 1. The oblique mesh cylinder 12 arranged inside the arc cover 9 plays a guiding role, which can ensure that the desiccant particles 31 flow into the interior of the arc cover 9 and will not flow out from the gap between the arc cover 9 and the inner wall of the ring network cabinet body 1, and absorb moisture and humidity at this time. After that, the saturated desiccant 8 accumulates at the conduit 5. At this time, the foot pedal 13 is stepped on regularly, and the connecting shaft on one side of the foot pedal 13 slides along the arc groove 22, which will drive the blocking plate 14 to rotate along the inner wall of the recovery box 7. At this time, the blocking plate 14 and the slot 28 are opened, and the saturated desiccant 8 falls from the slot 28 into the interior of the recovery box 7. After falling, the foot pedal 13 is released, and the blocking plate 14 blocks the slot 28 under the action of the curved spring 15, preventing the desiccant particles 31 that have not absorbed moisture from flowing into the interior of the recovery box 7. Then, the baffle 24 is opened to clean the saturated desiccant 8 inside the recovery box 7.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, Figure 1 , Figure 2 and Figure 6As shown, a plurality of circular grooves 17 are provided at equal intervals on one side of the ring network cabinet 1, and a magnetic plate 6 is snap-connected inside the plurality of circular grooves 17. When the inside of the ring network cabinet 1 is not inspected, the magnetic plate 6 can prevent external moisture from entering the inside of the ring network cabinet 1 through the circular groove 17. A slide groove 3 is provided on one side of the ring network cabinet 1, and a slider 18 is slidably connected inside the slide groove 3. The sliding connection between the slide groove 3 and the slider 18 can drive the L-shaped plate 19 to move up and down. The L-shaped plate 19 is fixedly mounted on the slider 18, and a humidity detector 20 is movably connected to the L-shaped plate 19. The humidity detector 20 detects moisture at various places inside the ring network cabinet 1, and a magnetic block 21 is fixedly connected to one end of the humidity detector 20. The magnetic block 21 is magnetically connected to the magnetic plate 6, so as to facilitate the adsorption of the magnetic plate 6 to prevent it from falling into the inside of the ring network cabinet 1.

[0035] A fire extinguishing assembly is placed on the top of the ring network cabinet 1, and the fire extinguishing assembly includes a storage box 4 for storing dry powder. When a fire accident occurs, the inside of the ring network cabinet 1 is extinguished. The storage box 4 is fixedly installed on the top of the ring network cabinet 1. A plurality of partition plates 25 are arranged inside the storage box 4. The interior of the storage box 4 is divided into a plurality of cavities by the partition plates 25. Dry powder can be stored separately to extinguish fire in certain specific fire areas. The interiors of the plurality of cavities are filled with dry powder, and the plurality of cavities are interspersed with discharge pipes 26. The ends of the plurality of discharge pipes 26 are provided with wax plates 27. The wax plates 27 block the ports of the discharge pipes 26 to prevent the dry powder from being discharged from the discharge pipes 26 when no accident occurs.

[0036] When used specifically, the present invention is a ring network cabinet with a built-in dehumidification component. When the humidity inside is detected, the sliding connection between the slide groove 3 and the slider 18 is used to drive the humidity detector 20 to detect the inside of the ring network cabinet 1. During the detection, the humidity detector 20 is moved to the corresponding circular groove 17, and then the humidity detector 20 is pushed to extend into the inside of the circular groove 17. At this time, the magnetic plate 6 and the magnetic block 21 are adsorbed together, so that the humidity detector 20 can penetrate into the inside of the ring network cabinet 1 for detection to determine the humidity conditions at different positions in the ring network cabinet. After the detection is completed, the humidity detector 20 is pulled out. Since the magnetic plate 6 is engaged with the circular groove 17, when the humidity detector 20 is completely pulled out, the magnetic plate 6 is engaged with the port of the circular groove 17 to form a seal to prevent external moisture from entering the inside of the ring network cabinet 1 through the circular groove 17;

[0037] When an accident such as a fire occurs inside, since the interior of the storage box 4 is divided into multiple cavities by the partition plate 25, dry powder is placed inside the multiple cavities. At this time, there is high temperature inside the ring network cabinet 1, and the high temperature will cause the wax plate 17 at the port of the drain pipe 26 to melt. After melting, the port of the drain pipe 26 opens, and the dry powder inside the corresponding cavity is sprinkled from the drain pipe 26 to extinguish the fire at the corresponding fire site.
