Abstract
Description
Technical Field
[0001] This invention relates to the field of power cabinet technology, and in particular to a power cabinet with moisture-proof function. Background Technology
[0002] In power systems, power distribution cabinets, as key equipment, play a vital role in protecting and distributing electrical energy and are widely used in various power facilities. However, during operation, the internal electronic components of power distribution cabinets generate a large amount of heat due to continuous operation. At the same time, moisture from the external environment can easily penetrate the cabinet. These two factors pose a serious threat to the stable operation of the power distribution cabinet and the lifespan of its components.
[0003] Traditional power cabinets often struggle to balance heat dissipation and moisture control. On one hand, to prevent overheating damage to internal electronic components, cooling devices such as fans or vents are typically installed to promote airflow and expel internal heat. However, this method, while introducing cool outside air, can also bring in moisture from the environment. On the other hand, some power cabinets with moisture-proof features use desiccants to absorb moisture, but these desiccants gradually become saturated after absorbing a certain amount of moisture, losing their moisture-proof capability. Moreover, due to a lack of effective synergistic design between heat dissipation and moisture control, the desiccant cannot quickly regain its drying properties after saturation, leading to a gradual increase in internal humidity. This can affect the normal operation of electronic components, shorten their lifespan, and even potentially cause safety accidents.
[0004] The desiccants used in existing power cabinets are prone to localized clumping during moisture absorption. This is because, under uneven airflow conditions, different parts of the desiccant absorb moisture differently, leading to excessive moisture absorption and clumping in some areas. Clumped desiccant not only significantly reduces its moisture absorption efficiency but also hinders airflow, further reducing its moisture-proof effect. Furthermore, when the desiccant needs replacement, the traditional design of power cabinets often makes the process cumbersome. It requires opening multiple components of the power cabinet and may even necessitate professional operation, which not only increases maintenance costs and time but also risks damaging other internal components during the replacement process.
[0005] To enable the recycling of desiccants, some electrical cabinets are designed with movable moisture-proof components. These components allow the desiccant to alternately absorb moisture and dry in different locations. However, in actual operation, the positioning and limiting mechanisms of these movable moisture-proof components have defects. Due to the lack of effective support and limiting structures, these components are prone to accidental movement due to vibration or airflow during operation, causing the desiccant to fail to accurately occupy the moisture-absorbing or drying position, thus affecting the normal functioning of the moisture-proof function. This not only reduces the moisture-proof effect of the electrical cabinet but may also lead to uncontrolled internal humidity, damaging electronic components. Summary of the Invention
[0006] To address the aforementioned problems, this invention proposes a power cabinet with moisture-proof function, which more precisely solves the problems mentioned in the background art.
[0007] This invention is achieved through the following technical solution:
[0008] This invention proposes a power cabinet with a moisture-proof function, including a connection between a stirring rod and a bearing seat. A geared disc is installed on the outer wall of the bearing seat, and a rack is installed on the inner bottom wall of the side box, with the rack meshing with the geared disc. When the drying section moves, the rack's limiting action drives the geared disc to rotate, which in turn drives the bearing seat to rotate. The bearing seat drives the stirring rod and the cabinet body via slots and pins. An exhaust fan is installed on the inner wall of the cabinet body, with an air inlet at the exhaust fan location and a heat dissipation hole at the overhead frame location. The air inlet allows cold air to enter, and the heat dissipation hole allows hot air to exit. A side box is installed on the side wall of the cabinet body, containing a movable, adjustable moisture-proof section. This movable moisture-proof section dries the air entering the cabinet body and includes a drying section for storing desiccant. Filter holes are provided on both sides of the drying section to filter dust from the incoming air. An upper partition is installed on the top of the drying section. The upper partition is installed on the inner wall of the side box, and the lower partition is installed at the bottom of the drying section. The lower partition is used to adjust the position of the drying section. The drying section includes a shell and a dividing plate. The shell is installed on the top of the lower partition, and the dividing plate is installed on the inner wall of the shell and divides the shell into two cavities: cavity one and cavity two. Both cavity one and cavity two contain desiccant. In the initial state, cavity one is located on one side of the exhaust fan and is used to adsorb water in the incoming cold air. When cavity one absorbs a lot of moisture, the lower partition is pulled to move cavity one to the heat dissipation hole so that the moisture in the desiccant in cavity one can evaporate when the hot air is discharged. At this time, cavity two is located at the air inlet and is used to adsorb moisture in the outside cold air. Conversely, the lower partition is pulled upwards.
[0009] Preferably, the inner wall of the cabinet is equipped with symmetrical overhead frames, which are used for the installation of the internal structure of the power cabinet. The exhaust fan is located between the two overhead frames, and the outer wall of the overhead frames is provided with air guide grooves, so that after the exhaust fan is started, the outside air enters between the two overhead frames through the air inlet, and then the internal hot air is discharged through the air guide grooves and heat dissipation holes.
[0010] Preferably, the side wall of the side box has an air inlet slot at the air inlet hole for the entry of cold air, an exhaust slot one at the top of the side box and an exhaust slot two at the bottom of the side box for the exhaust of hot air, and a wiping section is provided on the inner wall of the side box on the side of the drying section for cleaning the outer wall of the shell. The wiping section includes a mounting plate and a wiping head. The mounting plate is installed on the inner side wall of the side box, and the wiping head is installed on the end face of the mounting plate and in contact with the drying section. The side wall of the side box has a dust discharge slot one and a dust discharge slot two at the top and bottom of the wiping section for the discharge of dust after cleaning.
[0011] Preferably, both cavity one and cavity two are provided with a stirring part, which is used to stir the desiccant in cavity one and cavity two when the drying part moves. The stirring part includes a stirring rod installed on the inner wall of the drying part and extending to its back. Multiple stirring blades are installed on the outer wall of the stirring rod, and the stirring blades are used to stir the desiccant.
[0012] Preferably, a bearing seat is rotatably connected to the inner wall of the side box via a bearing. One end of the bearing seat has a slot, and a pin is installed at the end of the stirring rod. The pin is inserted into the slot. A toothed disc is installed on the outer wall of the bearing seat, and a rack is installed on the inner bottom wall of the side box. The rack meshes with the toothed disc and is used to drive the toothed disc to rotate by limiting the movement of the drying section.
[0013] Preferably, a limiting strip is installed on the back of the side box, which is used to limit the insertion of the drying section. A second cabinet door is installed on the outer wall of the side box for removing and replacing the drying section. A first cabinet door is installed on the outer wall of the cabinet.
[0014] Preferably, a support portion is provided on the inner bottom wall of the side box, the support portion being used to adjust the position of the movable moisture-proof part, and a limiting portion is installed on the side wall of the side box, the limiting portion being used to limit the position of the movable moisture-proof part after adjustment.
[0015] Preferably, the support includes a slide rod and a slider. The slide rod is installed on the inner wall of the side box, and the top of the slide rod is connected to the wiping part. The slider is disposed on the outer wall of the slide rod and can slide. The top of the slider is connected to the bottom of the lower partition. A support spring is installed between the slider and the side box, and the support spring is sleeved on the outer wall of the slide rod.
[0016] Preferably, the limiting part includes a pull rod installed on one side of the slider. The pull rod extends from the second exhaust groove to the outside of the side box. A limiting seat is installed on one side of the outer wall of the pull rod. A limiting plate is installed on the side wall of the side box. The limiting seat is sleeved on the outer wall of the limiting plate. The outer wall of the limiting plate has two limiting holes. The distance between the two limiting holes is half that of the drying part. A plug-in part is installed on the outer wall of the limiting seat. The plug-in part is inserted into the limiting hole.
[0017] Preferably, the insertion part includes a connecting spring, a connecting plate, and a plug rod. The connecting spring is installed on one side of the limiting seat, the connecting plate is installed at the end of the connecting spring, and the plug rod is installed at the end of the connecting plate. The plug rod is inserted into the limiting hole to limit the limiting hole.
[0018] Compared with the prior art, the present invention provides a power cabinet with moisture-proof function, which has the following beneficial effects:
[0019] This power cabinet with moisture-proof function has a movable moisture-proof section. It uses two chambers, one and two, to alternately absorb moisture and be dried by hot air to restore its dryness, ensuring continuous moisture protection and improving the operational stability of the entire device. At the same time, after the exhaust fan is started, outside air enters through the air inlet and is discharged through the air guide groove and heat dissipation hole, forming a good air circulation. This achieves the synergistic effect of moisture protection and heat dissipation, ensuring the normal operation of the power cabinet.
[0020] This moisture-proof power cabinet features a stirring section within its cavity. As the drying section moves, a rack, toothed disc, and other structures drive the stirring rod and blades to rotate, agitating the desiccant and ensuring more thorough contact between the desiccant and air. This improves moisture absorption efficiency, prevents localized clumping, and guarantees stable performance. A second cabinet door is installed on the outer wall of the side chamber, allowing the drying section to be opened and the desiccant replaced, ensuring the moisture-proof effect.
[0021] This moisture-proof power cabinet features a support section inside the side box. Through structures such as sliding rods, sliders, and support springs, the position of the movable moisture-proof section can be accurately adjusted, and the cavity can be switched. The support springs provide support force to keep it stable. A limiting section is also provided. Through structures such as pull rods, limiting seats, limiting plates, and plug-in parts, the movable moisture-proof section is limited after it is moved into place, preventing it from moving accidentally during the operation of the power cabinet and ensuring the stability of the moisture-proof function.

[0030] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings. Example 1
[0031] like Figures 1-7As shown in the figure, an embodiment of the present invention proposes a power cabinet with a moisture-proof function, including a cabinet body 1. An exhaust fan 3 is installed on the inner wall of the cabinet body 1. An air inlet 11 is opened at the location of the exhaust fan 3, and a heat dissipation hole 12 is opened at the location of the overhead frame 2. The air inlet 11 is used for cold air to enter the cabinet body 1, and the heat dissipation hole 12 is used for hot air to be discharged. A side box 4 is installed on the side wall of the cabinet body 1. An adjustable movable moisture-proof part 5 is provided inside the side box 4. The movable moisture-proof part 5 is used to dry the air entering the cabinet body 1. The movable moisture-proof part 5 includes a drying part 51 for storing desiccant. Filter holes are opened on both sides of the drying part 51 to filter dust in the incoming air. An upper partition 52 is provided at the top of the drying part 51 and is installed on the inner wall of the side box 4. A lower partition 53 is installed at the bottom of the drying part 51 and is used to adjust the position of the drying part 51. The drying section 51 includes a housing 511 and a dividing plate 512. The housing 511 is mounted on top of the lower partition 53, and the dividing plate 512 is mounted on the inner wall of the housing 511, dividing the housing 511 into two cavities: cavity one 513 and cavity two 514. Both cavity one 513 and cavity two 514 contain desiccant. In the initial state, cavity one 513 is located on one side of the exhaust fan 3 and is used to adsorb moisture from the incoming cold air. When cavity 1 513 absorbs a large amount of moisture, the lower partition 53 is pulled to move cavity 1 513 to the heat dissipation hole 12. At this time, the hot air is discharged and evaporates the moisture in the desiccant in cavity 1 513, restoring the desiccant's drying capacity. At this time, cavity 2 514 is located at the air inlet 11 and is used to absorb moisture in the cold air outside. Conversely, pulling the lower partition 53 upwards can interchange the positions of cavity 1 513 and cavity 2 514 to ensure continuous moisture-proof effect. Driven by the exhaust fan 3, the cold air outside will naturally be drawn into the cabinet 1. After the outside air enters, it will create a pressure difference inside. Under the action of pressure and because the heat dissipation hole 12 is connected to the outside, the internal hot air will be discharged because the pressure inside the cabinet 1 is greater than that outside.
[0032] In this invention, symmetrical overhead frames 2 are installed on the inner wall of the cabinet 1. The overhead frames 2 are used to install the internal structure of the power cabinet. An exhaust fan 3 is placed between the two overhead frames 2, and air guide grooves 21 are opened on the outer wall of the overhead frames 2. When the exhaust fan 3 is started, outside air enters between the two overhead frames 2 through the air inlet 11, and then exhausts the internal hot air through the air guide grooves 21 and heat dissipation holes 12, forming a good air circulation, which helps the power cabinet dissipate heat. At the same time, it works in conjunction with the movable moisture-proof part 5 to achieve the synergistic effect of moisture-proof and heat dissipation functions.
[0033] In this invention, an air inlet groove 41 is formed on the side wall of the side chamber 4 at the air inlet 11 to allow cold air to enter the side chamber 4. An exhaust groove 42 is formed on the top of the side chamber 4, and an exhaust groove 43 is formed on one side of the bottom of the side chamber 4 to allow hot air to exit. A wiping section 6 is provided on the inner wall of the side chamber 4 on one side of the drying section 51. The wiping section 6 is used to clean the outer wall of the housing 511. The wiping section 6 includes a mounting plate 61 and a wiping head 62. The mounting plate 61 is installed on the inner side wall of the side chamber 4, and the wiping head 62 is installed on the end face of the mounting plate 61 and contacts the drying section 51. A dust discharge groove 44 and a dust discharge groove 45 are formed on the side wall of the side chamber 4 at the top and bottom of the wiping section 6, respectively. After the wiping head 62 cleans the dust on the outer wall of the drying section 51, the dust can be discharged from the side chamber 4 through the dust discharge groove 44 and the dust discharge groove 45, keeping the inside of the side chamber 4 clean and preventing dust from affecting the performance of the desiccant and the normal operation of the power cabinet.
[0034] In this invention, both cavity one 513 and cavity two 514 are equipped with stirring units 54. The stirring units 54 are used to stir the desiccant in cavities one 513 and cavity two 514 when the drying unit 51 moves. The stirring unit 54 includes a stirring rod 541 installed on the inner wall of the drying unit 51 and extending to its back. Multiple stirring blades 542 are installed on the outer wall of the stirring rod 541. The stirring blades 542 are used to stir the desiccant. When the drying unit 51 moves, the stirring unit 54 moves accordingly, and the stirring blades 542 stir the desiccant, allowing for more thorough contact between the desiccant and air, improving the moisture absorption efficiency of the desiccant, and preventing localized clumping of the desiccant, thus ensuring the stability of the desiccant's performance.
[0035] In this invention, a bearing seat 46 is rotatably connected to the inner wall of the side box 4 via a bearing. A slot 461 is opened at one end of the bearing seat 46. A pin 543 is installed at the end of the stirring rod 541. The pin 543 is inserted into the slot 461 to achieve rotation, thereby realizing the stirring part 54 stirring the desiccant. No additional power source is required. The structure is reasonably designed and the operation is stable.
[0036] In this invention, a limiting strip 49 is installed on the back of the side box 4. When the drying unit 51 is inserted into the side box 4, the limiting strip 49 limits the drying unit 51, preventing it from shaking inside the side box 4 and ensuring its stable operation. A second cabinet door is installed on the outer wall of the side box 4. After the desiccant has been used for a period of time, the second cabinet door can be opened to remove the drying unit 51 and replace the desiccant, ensuring the moisture-proof effect. A first cabinet door is installed on the outer wall of the cabinet body 1, facilitating the inspection and maintenance of the equipment inside the power cabinet.
[0037] In this invention, a support part 7 is provided on the inner bottom wall of the side box 4. The support part 7 is used to adjust the position of the movable moisture-proof part 5, so that the movable moisture-proof part 5 can be accurately moved to the required position, realizing the position switching between cavity one 513 and cavity two 514. A limiting part 8 is installed on the side wall of the side box 4. The limiting part 8 is used to limit the position of the movable moisture-proof part 5 after the position is adjusted, preventing the movable moisture-proof part 5 from moving accidentally during the operation of the power cabinet, and ensuring the stability and reliability of the moisture-proof function.
[0038] In this invention, the support part 7 includes a sliding rod 71 and a slider 72. The sliding rod 71 is installed on the inner wall of the side box 4, and its top is connected to the wiping part 6. The slider 72 is disposed on the outer wall of the sliding rod 71 and can slide. The top of the slider 72 is connected to the bottom of the lower partition 53. A support spring 73 is installed between the slider 72 and the side box 4, and the support spring 73 is sleeved on the outer wall of the sliding rod 71. When it is necessary to adjust the position of the movable moisture-proof part 5, the slider 72 is pulled or pushed by external force to overcome the elasticity of the support spring 73, so that the slider 72 slides on the sliding rod 71, thereby driving the lower partition 53 and the drying part 51 to move, realizing the position switching between cavity one 513 and cavity two 514. After the adjustment is completed, the support spring 73 can provide a certain supporting force to keep the movable moisture-proof part 5 stable.
[0039] In this invention, the limiting part 8 includes a pull rod 81 installed on one side of the slider 72. The pull rod 81 extends from the second exhaust groove 43 to the outside of the side box 4, facilitating operation of the pull rod 81 by the operator from outside the side box 4. A limiting seat 82 is installed on one side of the outer wall of the pull rod 81, and a limiting plate 83 is installed on the side wall of the side box 4. The limiting seat 82 is sleeved on the outer wall of the limiting plate 83. Two limiting holes 831 are formed on the outer wall of the limiting plate 83. The distance between the two limiting holes 831 is half the distance between the drying part 51. When the movable moisture-proof part 5 is moved into place, the limiting seat 82 can correspond to one of the limiting holes 831. A plug-in part 84 is installed on the outer wall of the limiting seat 82. The plug-in part 84 is inserted into the limiting hole 831 to limit the position of the movable moisture-proof part 5, preventing it from moving during the operation of the power cabinet and ensuring the stability of the moisture-proof function.
[0040] In this invention, the insertion part 84 includes a connecting spring 841, a connecting plate 842, and an insertion rod 843. The connecting spring 841 is installed on one side of the limiting seat 82, the connecting plate 842 is installed at the end of the connecting spring 841, and the insertion rod 843 is installed at the end of the connecting plate 842. When the insertion rod 843 needs to be inserted into the limiting hole 831, the connecting plate 842 is pushed to overcome the elastic force of the connecting spring 841, so that the insertion rod 843 is inserted into the limiting hole 831, thereby limiting the limiting seat 82 and limiting the movable moisture-proof part 5. When the position of the movable moisture-proof part 5 needs to be adjusted, the connecting plate 842 is pulled to pull the insertion rod 843 out of the limiting hole 831, releasing the limitation, and then the movable moisture-proof part 5 can be moved. The connecting spring 841 provides a certain elastic force after the insertion rod 843 is inserted into the limiting hole 831, so that the insertion rod 843 and the limiting hole 831 are tightly fitted, ensuring a stable and reliable limiting effect.
[0041] In the workflow of this invention, cavity one 513 is located on one side of the exhaust fan 3, and cavity two 514 is located on the other side. At this time, cavity one 513 is used to absorb moisture from the incoming cold air, while cavity two 514 is ready for use. The limiting seat 82 corresponds to one of the limiting holes 831. The insertion rod 843 of the insertion part 84 is inserted into the limiting hole 831 to limit the movable moisture-proof part 5 and ensure its stability. The slider 72 is in a specific position under the supporting force of the supporting spring 73, stabilizing the drying part 51 in its initial state. When the exhaust fan 3 is started, external air enters between the two overhead frames 2 through the air inlet 11, and then the internal hot air is discharged through the air guide groove 21 and the heat dissipation hole 12, forming an air circulation that helps dissipate heat from the power cabinet. The cold air entering cabinet 1 first passes through side box 4, enters side box 4 through air inlet slot 41, and then passes through the drying section 51 of movable moisture-proof section 5. The desiccant in cavity 513 of drying section 51 absorbs moisture in the air, drying the air entering cabinet 1 and preventing the internal equipment of the power cabinet from getting damp. When cavity 513 absorbs a lot of moisture and needs to be dried, the operator pulls the lever 81 from the outside of side box 4, moving the limit seat 82 and pulling the plug 843 out of the limit hole 831, releasing the limit on movable moisture-proof section 5. Then, by overcoming the elasticity of support spring 73, the slider 72 is pulled or pushed, causing the slider 72 to slide on the slider 71, moving the lower partition 53 and drying section 51, pulling cavity 513 to the heat dissipation hole 12. At this time, cavity 514 is at air inlet 11, used to absorb moisture in the outside cold air. When the drying section 51 moves, the pin 543 at the end of the stirring rod 541 inserts into the slot 461 of the bearing seat 46. At the same time, the gear plate 47 on the outer wall of the bearing seat 46 meshes with the rack 48 on the inner bottom wall of the side box 4. The rack 48 limits the rotation of the gear plate 47, which in turn drives the bearing seat 46 to rotate. The bearing seat 46 drives the stirring rod 541 to rotate through the slot 461 and the pin 543. The stirring blade 542 stirs the desiccant, making the desiccant come into more full contact with the air, improving the moisture absorption efficiency and preventing local clumping. When the movable moisture-proof section 5 is in place, the limiting seat 82 corresponds to another limiting hole 831 and pushes the connecting plate 842 to overcome the elastic force of the connecting spring 841, so that the rod 843 is inserted into the limiting hole 831, thereby limiting the limiting seat 82 and limiting the movable moisture-proof section 5 to prevent it from moving during the operation of the power cabinet. After cavity 1 513 moves to the heat dissipation hole 12, the hot air will evaporate the desiccant that has absorbed a lot of moisture inside cavity 1 513, restoring the desiccant's drying capacity. When cavity 2 514 absorbs a lot of moisture, the lower partition 53 is pulled upwards in the reverse order of the above moving and limiting operations, thereby swapping the positions of cavity 1 513 and cavity 2 514 and ensuring continuous moisture protection.The wiping section 6 on the inner wall of the side box 4 can clean the outer wall of the drying section 51. After the wiping head 62 cleans the dust on the outer wall of the drying section 51, the dust is discharged from the side box 4 through the first dust discharge trough 44 and the second dust discharge trough 45, keeping the inside of the side box 4 clean and preventing dust from affecting the performance of the desiccant and the normal operation of the power cabinet. After the desiccant has been used for a period of time, the cabinet door 2 on the outer wall of the side box 4 can be opened to remove the drying section 51 and replace the desiccant to ensure the moisture-proof effect. At the same time, the cabinet door 1 on the outer wall of the cabinet body 1 facilitates the inspection and maintenance of the equipment inside the power cabinet.
