Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to a rainproof and moisture-proof outdoor power cabinet. Background Art

[0002] The distribution cabinet is an important equipment used in the power field. Through the setting of the distribution cabinet, multiple components of the power equipment can be integrated inside the distribution cabinet for centralized control, thereby improving the safety of power operation.

[0003] Some power distribution cabinets, particularly those used in industrial automation, power transmission and distribution, and renewable energy, utilize modules or devices containing insulated gate bipolar transistors (IGBTs). This is because IGBTs offer high voltage and current handling capabilities, along with excellent switching characteristics, enabling efficient control and conversion of power. When used outdoors, distribution cabinets are susceptible to moisture from the external environment. Once moisture accumulates inside the cabinet, it can damage internal electrical components such as the IGBT modules. To ensure the proper functioning of these components, existing cabinets typically incorporate moisture removal mechanisms.

[0004] However, the dehumidification mechanism inside the existing distribution cabinet can usually only be used in normal weather. Once it rains, in order to avoid bringing rainwater into the distribution cabinet, the dehumidification mechanism is usually stopped. However, if the dehumidification mechanism is stopped on rainy days, the rainwater dripping on the outer wall of the distribution cabinet will easily cause the temperature of the outer wall to drop, forming a temperature difference with the air inside the cabinet, thereby condensing into water vapor to increase the internal humidity, affecting the use of the entire insulated gate bipolar transistor chip and other electrical components. At the same time, desiccant is usually used inside the existing distribution cabinet to adsorb moisture, but the existing desiccant is usually piled together for moisture absorption and simply hung inside the cabinet. When the desiccant is piled together, the internal desiccant particles are covered by the outer particles, reducing the surface area exposed to the air, resulting in a decrease in the overall adsorption efficiency of the desiccant, which is not conducive to the desiccant's moisture absorption.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 12A rainproof and moisture-proof outdoor power cabinet includes a cabinet body 1. An exhaust pipe 11 is provided in the interior of the cabinet body 1. External magnets 37 are provided on both sides of the exhaust pipe 11. A fixing plate 18 is fixedly connected to the interior of the exhaust pipe 11. A dual-axis motor 21 is fixedly connected to the outer wall of the fixing plate 18. A transmission rod 22 is provided at the upper output end of the dual-axis motor 21. A regenerative moisture absorption mechanism is provided on the transmission rod 22.

[0035] The regeneration moisture absorption mechanism includes a storage box 23 arranged at the end of the transmission rod 22. A moisture removal port is provided on the side wall of the storage box 23. A heating ring 36 is provided at the bottom of the storage box 23. A friction rod 35 is fixedly connected to the outer wall of the upper end of the dual-axis motor 21. The heating ring 36 and the friction rod 35 are both made of frosted material. The friction rod 35 is in sliding contact with the heating ring 36. The storage box 23 is hollow inside. A plurality of brackets 31 are fixedly connected to the outer wall of the storage box 23. A rotating shaft 32 is rotatably connected to the plurality of brackets 31. A circulation pipe 33 is provided inside the rotating shaft 32.

[0036] A plurality of sealing films 24 are provided on the outer wall of the storage box 23, and the ends of the plurality of circulation tubes 33 respectively pass through the corresponding sealing films 24 to the interior of the storage box 23. The side wall of the circulation tube 33 is fixedly connected to the sealing film 24, and the end of the circulation tube 33 away from the sealing film 24 is connected to a cylinder 34. The cylinder 34 is hollow, and the interior of the cylinder 34 is fixedly connected to a mounting plate 38. A reciprocating screw 39 is rotatably connected to the mounting plate 38, and a stirring plate 43 is provided at the end of the reciprocating screw 39. A moving rod 40 is slidingly provided on the end of the cylinder 34 away from the circulation tube 33. The moving rod 40 is hollow, and the end of the moving rod 40 is fixedly connected to a pressing magnet 42. A pressing spring 41 is sleeved on the outer wall of the moving rod 40, and the end of the pressing spring 41 away from the cylinder 34 is in contact with the pressing magnet 42.

[0037] The movable rod 40 is fixedly connected to a pull ring 44 on one side inside the cylinder 34 , and the pull ring 44 is threadedly sleeved on the outer wall of the reciprocating screw 39 . The outer walls of multiple cylinders 34 are fixedly connected to a protrusion 29 , and the swing arm 28 is rotatably connected to the protrusion 29 .

[0038] In this embodiment, when dehumidifying the cabinet 1 in normal weather, the operator can turn on the dual-axis motor 21 to drive the exhaust fan 20 to rotate. When the exhaust fan 20 rotates, dry air from the outside can be sucked into the cabinet 1 and then circulated out through the filter 5. When air circulates inside the cabinet 1, the cabinet 1 can be dehumidified. When the exhaust fan 20 rotates to extract air and dehumidify, it also drives the contact magnet 19 to rotate synchronously. When the contact magnet 19 intermittently rotates to just above the trigger magnet 17, the entire filter plate 14 will vibrate under the combined action of the intermittent repulsive magnetic force and the tension of the tension spring 16. The vibrating filter plate 14 can not only filter the air sucked into the cabinet 1, but also shake off the dust left on the surface of the filter plate 14 to avoid clogging of the filter plate 14 and affecting the overall fluidity.

[0039] Example 2: Please refer to Figure 1 - Figure 12 This embodiment further explains Example 1. A driving rod 25 is fixedly connected to the outer wall of the storage box 23, and a pressure ring 26 is slidably connected to the driving rod 25. An outward rod 27 is fixedly connected between the storage box 23 and the pressure ring 26. A plurality of connecting parts 30 are fixedly connected to the pressure ring 26, and a plurality of swing arms 28 are rotatably connected to the corresponding connecting parts 30 at one end away from the protrusion 29.

[0040] An exhaust fan 20 is provided at the lower output end of the dual-axis motor 21 , and a vibration dust removal mechanism is provided on the outer side wall of the exhaust fan 20 .

[0041] The vibration dust removal mechanism includes a contact magnet 19 fixedly connected to the exhaust fan 20. Slide grooves 15 are provided on both sides of the exhaust pipe 11. Filter plates 14 are slidably connected to the interiors of the slide grooves 15 on both sides.

[0042] A tension spring 16 is fixedly connected to the inside of the slide groove 15, and the other end of the tension spring 16 is fixedly connected to the outer wall of the filter plate 14. Trigger magnets 17 are fixedly connected to both sides of the filter plate 14. The magnetic poles of the trigger magnets 17 are the same as those of the contact magnets 19.

[0043] An exhaust port 4 is provided at the upper end of the cabinet body 1, a filter screen 5 is provided inside the exhaust port 4, inner grooves 7 are provided on both sides of the exhaust port 4, a baffle 6 is slidably connected to the inside of the inner groove 7, and telescopic rods 8 are provided on both sides of the baffle 6, and the other end of the telescopic rod 8 is fixedly connected to the inner wall of the inner groove 7.

[0044] A cover 12 is fixedly connected just below the exhaust pipe 11 , and electric rods 13 are fixedly connected to both sides of the cover 12 . One end of the electric rod 13 away from the cover 12 is fixedly connected to the outer wall of the cabinet 1 .

[0045] A flip door 2 is rotatably connected to the cabinet body 1, a handle 3 is fixedly connected to the outer wall of the flip door 2, a support plate 10 and an electrical component box 9 are fixedly connected inside the cabinet body 1, and an insulated gate bipolar transistor chip is arranged inside the electrical component box 9.

[0046] In this embodiment, when the dual-axis motor 21 drives the exhaust fan 20 to rotate, it also drives the storage box 23 to rotate through the transmission rod 22. When the storage box 23 rotates, the friction rod 35 on the dual-axis motor 21 will continuously rub against the heating ring 36. Since both are made of frosted material, a large amount of heat will be generated when the two rub against each other, which will be conducted to the inside of the storage box 23 by the heating ring 36, thereby heating the silica gel desiccant accumulated inside the storage box 23 (it should be noted that the side of the heating ring 36 located inside the storage box 23 is made of brass material, which has extremely strong thermal conductivity). When the silica gel desiccant is accumulated inside the storage box 23 and heated, the air gap between the silica gel desiccant becomes smaller, and the smaller gap is equivalent to reducing The heat-insulating effect of the air layer is lost, and the heat exchange area with the surrounding environment is also reduced, thereby reducing the rate of heat loss to the surrounding environment, allowing heat to be more concentratedly transferred and accumulated inside the silica gel desiccant, improving the heating effect, and thus increasing the regeneration speed of the entire silica gel desiccant. When the silica gel desiccant is heated and regenerated inside the storage box 23, the outrigger rod 27 is in an extended state. When the outrigger rod 27 is extended and pushes the pressure ring 26 to move up on the surface of the driving rod 25, it will pull the multiple cylinders 34 upward through the swing arm 28 to tilt. When the cylinder 34 is in a tilted state, the silica gel desiccant inside the storage box 23 cannot be thrown into the cylinder 34 and can only accumulate inside the storage box 23.

[0047] When dehumidifying the interior of the cabinet 1 on rainy days, the operator can control the electric rod 13 to retract, so that the cover 12 blocks the exhaust pipe 11 to prevent external moisture from entering the cabinet 1 through the filter plate 14. When the exhaust pipe 11 is closed, the operator can also control the two telescopic rods 8 to retract synchronously. When the telescopic rods 8 retract, the baffles 6 on both sides of the exhaust port 4 will close to block the exhaust port 4, also preventing external moisture from entering the cabinet 1. When the exhaust pipe 11 and the filter 5 are both closed, the operator first stops the rotation of the exhaust fan 20 of the dual-axis motor 21, so that the exhaust fan 20 no longer draws air into the cabinet 1. The wind blows, and then increases the power to allow the dual-axis motor 21 to drive the storage box 23 to rotate rapidly. When the dual-axis motor 21 drives the storage box 23 to rotate rapidly, the outrigger 27 is controlled to retract. When the outrigger 27 retracts, it drives the pressure ring 26 to move downward. The downward pressure ring 26 makes the multiple cylinders 34 horizontal through multiple swing arms 28. When the cylinders 34 are horizontal and the storage box 23 rotates rapidly, the silica gel desiccant inside the storage box 23 will be thrown into the cylinder 34 through the circulation tube 33. When the silica gel desiccant enters the cylinder 34, the power of the dual-axis motor 21 can be reduced at this time, allowing the transmission rod 22 to drive the cylinder The cylinder 34 rotates slowly. When the horizontal cylinder 34 drives the pressing magnetic block 42 to rotate slowly and intermittently to the side of the outer magnet 37, the moving rod 40 will reciprocate inside the cylinder 34 under the combined action of the intermittent magnetic force of the outer magnet 37 and the pressing magnetic block 42 and the elastic force of the pressing spring 41. When the moving rod 40 drives the pull ring 44 to reciprocate on the surface of the reciprocating screw 39, the reciprocating screw 39 will drive the entire stirring plate 43 to rotate. When the stirring plate 43 rotates, it will stir and overturn the silica gel desiccant inside the cylinder 34, preventing the silica gel desiccant inside the cylinder 34 from absorbing too much moisture and agglomerating, while also allowing the silica gel to dry. The agent disperses and absorbs moisture to improve the dehumidification effect. After the rainy day, when the silica gel desiccant is no longer needed for dehumidification, referring to the above principle, the outrigger rod 27 can be extended to allow the multiple cylinders 34 to flip upward and be in an inclined state. When the cylinder 34 is in an inclined state, the silica gel desiccant inside the cylinder 34 will return to the storage box 23 through the circulation tube 33, and the storage box 23 will heat and regenerate the silica gel desiccant. By switching between the two modes of dehumidification by exhaust and desiccant adsorption, the entire cabinet 1 can be effectively dehumidified under any circumstances, ensuring the normal use of the insulated gate bipolar transistor chip and other electrical components inside the electrical component box 9.

[0048] It should be noted that the sealing film 24 is made of silicone rubber and has good ductility. When the circulation tube 33 is turned upside down, the sealing film 24 can be adaptively extended to always seal the storage box 23.

[0049] It should be noted that the entire cabinet is made of fiberglass, which has good corrosion resistance and is not corroded by acids, alkalis, salts and other chemical substances, and can effectively resist the corrosion of rainwater.
