Description

Technical Field

[0001] This disclosure belongs to the field of electrical equipment technology, and specifically relates to a power distribution cabinet. Background Technology

[0002] Distribution cabinets, as a type of device used to protect multiple electrical components (such as electrical switches), are widely deployed in various locations, such as factories and the field.

[0003] In related technologies, when a power distribution cabinet is deployed outdoors, to improve the electrical safety of the components inside, the cabinet includes an exhaust system, a cabinet body, a box, and a desiccant (such as activated carbon granules) placed inside the box. The exhaust system is located outside the cabinet and connected to the side wall of the cabinet body. The box is fixed to the bottom or side wall of the cabinet body. When the power distribution cabinet is in use, the exhaust system draws the gas from inside the cabinet body and injects it into the box. The desiccant in the box dries the injected gas, and the dried gas re-enters the power distribution cabinet to dissipate heat.

[0004] However, after a period of use, the desiccant inside the distribution cabinet will become saturated with water and unable to continue dehumidifying. Therefore, it is necessary to replace the desiccant inside the cabinet regularly. When replacing the desiccant, the cabinet needs to be removed from the cabinet, then new desiccant needs to be refilled, and then the cabinet needs to be reassembled. The replacement process is time-consuming and labor-intensive. Summary of the Invention

[0005] This disclosure provides a power distribution cabinet that can improve the efficiency of desiccant replacement and save costs. The technical solution is as follows: This disclosure provides a power distribution cabinet, which includes a cabinet body, an exhaust assembly, a housing, and a rotating component. The exhaust assembly is connected to the side wall of the cabinet body, and the exhaust end of the exhaust assembly communicates with the interior of the cabinet body. The housing is located at the bottom of the cabinet body, and its top is connected to the bottom of the cabinet body. The bottom of the housing has an opening, and the side walls of the housing have an air inlet and an air outlet, respectively. The air outlet communicates with the interior of the cabinet body, and the air inlet communicates with the air outlet of the exhaust assembly. The rotating component is located in the housing and defines a first drying chamber for containing a desiccant. The rotating component is configured to rotate within the housing body, causing the first drying chamber to move between a first position and a second position. When the first drying chamber is in the first position, it communicates with the opening; when the first drying chamber is in the second position, it communicates with the air inlet and the air outlet of the housing body.

[0006] In another implementation of this disclosure, the cabinet includes a fixed shaft and a shell, with both ends of the fixed shaft connected to the shell, and the axial direction of the fixed shaft perpendicular to the height direction of the cabinet; the rotating component includes a sleeve and at least two partitions, the sleeve being rotatably fitted over the fixed shaft; the at least two partitions are arranged circumferentially along the fixed shaft, each partition being connected to the outer wall of the sleeve at both ends along the axis of the fixed shaft, and the radially outward side of the partition along the fixed shaft is used for sealing contact with the inner wall of the top of the cabinet; the first drying chamber is defined between two adjacent partitions, the outer wall of the sleeve, the outer wall of the fixed shaft, and the shell.

[0007] In another implementation of this disclosure, the rotating component and the interior of the housing further define a second drying chamber for containing a desiccant. The first drying chamber and the second drying chamber are centrally symmetrically distributed about the axis of the fixed shaft. When the first drying chamber is connected to the opening, the second drying chamber is connected to the air inlet and the air outlet of the housing, respectively. When the second drying chamber is connected to the opening, the first drying chamber is connected to the air inlet and the air outlet of the housing, respectively.

[0008] In another implementation of this disclosure, the sleeve includes two sub-sleeves, which are coaxial and distributed around both ends of the fixed shaft and connected to the partition; the fixed shaft is a hollow tube, one end of which is located outside the housing and connected to the exhaust end of the exhaust assembly; the fixed shaft has multiple through holes on the side facing the cabinet, which are spaced apart between the two sleeves along the axis of the fixed shaft, and each through hole communicates with the drying chamber adjacent to the cabinet.

[0009] In another implementation of this disclosure, there are four partitions, which are evenly distributed circumferentially along the fixed axis; the air inlet and the air outlet are located on opposite sides of the housing along the axis of the fixed axis; the rotating component also includes a plurality of perforated plates, which are divided into two groups, each group corresponding to the first drying chamber and the second drying chamber respectively. Each group includes a plurality of perforated plates spaced along the axis of the fixed axis, and each group is located in the corresponding drying chamber and connected to two adjacent partitions in the corresponding drying chamber. The perforated plates have a plurality of vent holes for gas flow.

[0010] In another implementation of this disclosure, the rotating component further includes a rotating rod and a positioning rod. The rotating rod is an L-shaped rod. The first end of the rotating rod is inserted into one of the sub-sleeves and connected to the sub-sleeve. The second end of the rotating rod is located outside the housing, and the outer wall near the second end is opposite to the side wall of the housing. The middle part of the rotating rod is rotatably connected to the housing. The positioning rod is located outside the housing, and one end is movably inserted into the outer wall of the rotating rod near the second end. The positioning rod can rotate with the rotating rod. The other end of the positioning rod is used to insert into the housing after the rotating rod has finished rotating. The axial direction of the positioning rod is the axial direction of the sleeve.

[0011] In another implementation of this disclosure, an end plate is connected to the end of the positioning rod away from the housing; the rotating component further includes a first elastic reset component, which is sleeved on the positioning rod and has its two ends respectively clamped between the end plate and the end of the rotating rod.

[0012] In another implementation of this disclosure, the side wall near the bottom of the housing has a feed inlet, which communicates with the interior of the housing. When the first drying chamber communicates with the opening, the first drying chamber is also communicated with the feed inlet. The power distribution cabinet further includes a baffle assembly, which includes a baffle plate. The baffle plate is movably located at the bottom of the housing and connected to the housing. The baffle plate is configured to block the opening or open the opening.

[0013] In another implementation of this disclosure, the material blocking assembly further includes a first slider and a second elastic reset member. The first slider is movably located in the side wall of the housing and connected to the baffle. The movement direction of the first slider is the height direction of the housing. The second elastic reset member is located on one side of the first slider along the movement direction of the first slider, and its two ends are respectively clamped between the first slider and the inner wall of the housing. The extension and retraction direction of the second elastic reset member is the same as the movement direction of the first slider.

[0014] In another implementation of this disclosure, the distribution cabinet further includes a flow guiding assembly, which includes a flow guiding plate, a second slider, and a third elastic reset member. The flow guiding plate is movably located on the side of the baffle away from the housing. The second slider is movably located at the bottom of the baffle and connected to the flow guiding plate. The movement direction of the second slider is perpendicular to the movement direction of the first slider. The third elastic reset member is located on one side of the second slider along the movement direction of the second slider, and its two ends are respectively clamped between the second slider and the baffle.

[0015] The beneficial effects of the technical solutions provided in this disclosure are: Because the distribution cabinet has a rotatable rotating component inside the cabinet, and this rotating component defines a first drying chamber for containing desiccant, the rotating component is configured to rotate within the cabinet, allowing the first drying chamber to move between a first position and a second position. When the first drying chamber is in the first position, it communicates with the opening; when the first drying chamber is in the second position, it communicates with the air inlet and air outlet of the cabinet. Therefore, the rotating component can be controlled to rotate to the first position, where the first drying chamber communicates with the opening, allowing the desiccant to be discharged from the drying chamber through the opening. After discharge, the desiccant can be refilled. Then, the rotating component can be rotated to the second position, allowing the first drying chamber to communicate with both the air inlet and air outlet of the cabinet. Since the first drying chamber is now connected to both the air inlet and air outlet, the humid air drawn from the cabinet by the exhaust assembly can enter the first drying chamber and be dried by the desiccant. Furthermore, the dried air can be blown back into the cabinet through the air outlet to cool the interior of the cabinet.

[0016] In other words, the power distribution cabinet provided in this embodiment has a rotating component inside the cabinet. This allows control over whether the first drying chamber defined by the rotating component and the cabinet is connected to an opening. If the desiccant needs to be replaced, the rotating component is controlled to connect the first drying chamber to the opening. If the desiccant in the first drying chamber needs to dry the gas extracted from the cabinet by the exhaust assembly, the rotating component is controlled to connect the first drying chamber to both the air inlet and outlet, avoiding disassembly and assembly of the cabinet, greatly saving steps and improving efficiency.

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0021] This disclosure provides a power distribution cabinet, such as... Figure 1 As shown, the power distribution cabinet includes an exhaust assembly 2, a housing 3, and a rotating component 4.

[0022] The exhaust assembly 2 is located on one side of the housing 3 and is connected to the side wall of the cabinet 1. The exhaust end of the exhaust assembly 2 is connected to the interior of the cabinet 1.

[0023] Figure 2 for Figure 1 A sectional view along the AA direction, combined with Figure 2 The bottom of the cabinet 3 has an opening 300, and the side walls of the cabinet 3 have an air inlet 302 and an air outlet 303 respectively. The air outlet 303 is connected to the interior of the cabinet 1, and the air inlet 302 is connected to the air outlet of the exhaust assembly 2.

[0024] The rotating member 4 is located in the housing 3 and defines a first drying chamber 401 for containing desiccant with the interior of the housing 3. The rotating member 4 is configured to rotate in the housing 3 so that the first drying chamber 401 moves between a first position and a second position. When the first drying chamber 401 is in the first position, it communicates with the opening 300 and is not communicated with the air inlet 302 and the air outlet 303. When the first drying chamber 401 is in the second position, it communicates with the air inlet 302 and the air outlet 303 of the housing 3 and is not communicated with the opening 300.

[0025] When the power distribution cabinet provided in this embodiment is used, since the cabinet has a rotating component 4 inside the housing 3, and the rotating component 4 and the interior of the housing 3 define a first drying chamber 401 for containing desiccant, the rotating component 4 is configured to rotate within the housing 3 so that the first drying chamber 401 moves between a first position and a second position. When the first drying chamber 401 is in the first position, it communicates with the opening 300; when the first drying chamber 401 is in the second position, it communicates with the air inlet 302 and the air outlet 303 of the housing 3. Therefore, the rotating component 4 can be controlled to rotate to the first position, and when the first drying chamber 401 communicates with the opening 300, the desiccant in the first drying chamber 401 can be discharged through the opening 300. After discharge, the desiccant can be refilled. Then, the rotating part 4 can be controlled to rotate to the second position, so that the first drying chamber 401 is connected to the air inlet 302 and the air outlet 303 of the cabinet 3 respectively. Since the first drying chamber 401 is connected to the air inlet 302 and the air outlet 303 respectively, the humid air drawn out by the exhaust assembly 2 from the cabinet 1 can enter the first drying chamber 401 and be dried by the desiccant. Moreover, the dried air can be blown back into the cabinet 1 through the air outlet 303 to cool the inside of the cabinet 1.

[0026] In other words, the power distribution cabinet provided in this embodiment has a rotating component 4 inside the housing 3. This allows control over whether the rotating component 4 and the first drying chamber 401 defined by the housing 3 are connected to the opening 300. If the desiccant needs to be replaced, the rotating component 4 is controlled to be in the first position, connecting the first drying chamber 401 to the opening 300. If the desiccant in the first drying chamber 401 is needed to dry the gas extracted from the cabinet 1 by the exhaust assembly 2, the rotating component 4 is controlled to be in the second position, connecting the first drying chamber 401 to both the air inlet 302 and the air outlet 303. This avoids disassembling the housing 3, significantly saving steps and improving efficiency.

[0027] See also Figure 1The exhaust assembly 2 includes an exhaust fan 21 and an exhaust duct 22. The exhaust fan 21 is located outside the side wall of the cabinet 1 and is connected to the side wall of the cabinet 1. One end of the exhaust fan 21 is connected to the interior of the cabinet 1, and the other end is connected to the exhaust duct 22. The other end of the exhaust duct 22 is inserted into the side wall of the housing 3 near the top and is connected to the air inlet 302.

[0028] Due to varying operating environments, in humid environments, prolonged operation of the distribution cabinet can lead to moisture-laden air entering the cabinet 1, affecting the normal operation of the electrical components inside. In such cases, the exhaust fan 21 is activated, drawing the moisture-laden air out of the cabinet 1. This air then travels along the exhaust duct 22 into the housing 3 and into the first drying chamber 401, where the desiccant dries the air. The dried air then re-enters the cabinet 1 through the air outlet 303, ensuring proper airflow and facilitating heat dissipation for the electrical components.

[0029] To facilitate control of the exhaust fan 21, the exhaust fan 21 can be connected to a controller, so that remote control can be achieved simply by using the controller.

[0030] In this embodiment, the exhaust assembly 2 further includes an exhaust pipe 23, one end of which is connected to the interior of the cabinet 1, and the other end of which is connected to an exhaust port 303. The exhaust port 303 is connected to the interior of the cabinet 1 through the exhaust pipe 23.

[0031] In addition, to prevent desiccant from entering the exhaust duct 23 and the exhaust duct 22, filter screens 24 are fixedly connected to the inner walls of both the exhaust duct 22 and the exhaust duct 23. The filter screens 24 are used to filter the flowing air and prevent desiccant and other impurities from entering the cabinet 1.

[0032] Combination Figure 2 Optionally, the cabinet 3 includes a fixed shaft 31 and a cabinet shell 32. The two ends of the fixed shaft 31 are connected to the cabinet shell 32 respectively, and the axial direction of the fixed shaft 31 is perpendicular to the height direction of the cabinet 1.

[0033] The rotating component 4 includes a sleeve 41 and at least two partitions 42. The sleeve 41 is rotatably fitted over the fixed shaft 31. The at least two partitions 42 are arranged circumferentially around the fixed shaft 31. Each partition 42 is connected to the outer wall of the sleeve 41 at both ends along the axis of the fixed shaft 31. The radially outward side of the partition 42 is used for sealing contact with the inner wall of the top of the housing 3. A first drying chamber 401 is defined between two adjacent partitions 42, the outer wall of the sleeve 41, the outer wall of the fixed shaft 31, and the housing 32.

[0034] In the above implementation, two sleeves 41 are rotatably connected to both ends of the fixed shaft 31, respectively. At least two partitions 42 define the first drying chamber 401 with the sleeves 41, the fixed shaft 31, and the housing 32. Thus, when the sleeves 41 rotate, the partitions 42 rotate accordingly, and the first drying chamber 401 moves accordingly, ultimately enabling the first drying chamber 401 to communicate with the opening 300 or with the air inlet 302 and the air outlet 303.

[0035] For example, since the partition 42 rotates together with the sleeve 41, the trajectory formed by the partition 42 after rotating with the sleeve 41 is a circle with the center of the sleeve 41 as the center.

[0036] To ensure that the first drying chamber 401 defined between the partition 42 and the housing 3 is a sealed chamber when drying the gas extracted from the cabinet 1, the interior of the housing 32 has a cylindrical cavity. The circumference of the cylindrical cavity is the same as the movement trajectory of the partition 42. Moreover, the opening 300 is located on one side of the axis of the cylindrical cavity and communicates with the cylindrical cavity.

[0037] In addition, to ensure that the first drying chamber 401 is a sealed chamber when drying the gas extracted from the cabinet 1, each partition 42 is provided with a sealing groove along the radial direction of the sleeve 41 and on the side away from the sleeve 41, and a sealing strip is installed in the sealing groove. The sealing strip contacts the inner wall of the cylindrical cavity. The sealing strip ensures the sealing at the contact point between the partition 42 and the cabinet 3.

[0038] Optionally, the rotating component 4 and the interior of the housing 3 further define a second drying chamber 402 for containing a desiccant, and the first drying chamber 401 and the second drying chamber 402 are centrally symmetrical about the axis of the fixed shaft 31.

[0039] When the first drying chamber 401 is connected to the opening 300, the second drying chamber 402 is connected to the air inlet 302 and the air outlet 303 of the housing 3. When the second drying chamber 402 is connected to the opening 300, the first drying chamber 401 is connected to the air inlet 302 and the air outlet 303 of the housing 3.

[0040] In the above implementation, a first drying chamber 401 and a second drying chamber 402 are respectively provided, allowing the first drying chamber 401 and the second drying chamber 402 to be used alternately. For example, when the first drying chamber 401 is drying the gas extracted from the cabinet 1, the second drying chamber 402 can release and replace the desiccant. Then, when the first drying chamber 401 needs to replace the desiccant, simply control the rotating component 4 to connect the first drying chamber 401 with the opening 300, while the second drying chamber 402 can continue to dry the gas extracted from the cabinet 1, ensuring that while one of the first drying chamber 401 and the second drying chamber 402 is replacing the desiccant, the other can still continue to dry the gas extracted from the cabinet 1.

[0041] In this embodiment, there are four partitions 42, which are evenly spaced along the circumference of the sleeve 41. Two adjacent partitions 42, the outer wall of the sleeve 41, the outer wall of the fixed shaft 31, and the inner wall of the housing 32 define a first drying chamber 401, and the other two partitions 42, the outer wall of the sleeve 41, the outer wall of the fixed shaft 31, and the inner wall of the housing 32 define a second drying chamber 402.

[0042] Figure 3 for Figure 1 The enlarged view at point B in the middle, combined with Figure 3 Optionally, the sleeve 41 includes two sub-sleeves 411, which are coaxial and distributed around the two ends of the fixed shaft 31 and are both connected to the partition plate 42.

[0043] The fixed shaft 31 is a hollow tube. One end of the fixed shaft 31 is located outside the housing 32 and is connected to the air outlet of the exhaust assembly 2. The side of the fixed shaft 31 facing the cabinet 1 has multiple through holes 310. The multiple through holes 310 are arranged at intervals between the two sleeves 41 along the axis of the fixed shaft 31. Each through hole 310 is connected to the drying chamber, which is connected to both the air inlet 302 and the air outlet 303.

[0044] In the above implementation, the fixed shaft 31 is a hollow tube, allowing the gas extracted by the exhaust assembly 2 to flow along the interior of the fixed shaft 31 and then enter the drying chamber, which is connected to the air inlet 302 and the air outlet 303, through the through hole 310 on the fixed shaft 31, so that it can be dried by the desiccant in the drying chamber. That is, the fixed shaft 31 and the through hole 310 on the fixed shaft form another air path, accelerating the absorption of moisture.

[0045] For ease of connection, the fixed shaft 31 is an L-shaped pipe fitting. One end of the fixed shaft 31 is connected to the exhaust pipe 22 of the exhaust assembly 2.

[0046] See also Figure 1 and Figure 2Optionally, the air inlet 302 and air outlet 303 of the housing 3 are located on opposite sides of the housing 3 along the axial direction of the sleeve 41.

[0047] The rotating component 4 also includes multiple perforated plates 43, which are divided into two groups. The two groups are centrally symmetrical about the center of the sleeve 41 and correspond one-to-one with the first drying chamber 401 and the second drying chamber 402, respectively. Each group includes multiple perforated plates 43 spaced apart along the axis of the sleeve 41. The multiple perforated plates 43 in each group are located in the corresponding drying chamber and are connected to two adjacent partitions 42 in the corresponding drying chamber. The perforated plates 43 are provided with multiple vent holes 430 for gas flow.

[0048] In the above implementation, the perforated plate 43 is set in the corresponding drying chamber, which increases the resistance of the blowing air and prolongs the residence time of the airflow in each drying chamber, so that the desiccant (activated carbon particles) in the drying chamber can fully dry the airflow with moisture.

[0049] In this embodiment, each perforated plate 43 is a flat plate and is arranged at an angle, with the plate surface of the perforated plate 43 forming an acute angle with the axial direction of the sleeve 41. Along the direction from the top to the bottom of the housing 3, the distance between the perforated plate 43 located on the top side of the housing 3 and the air inlet 302 increases.

[0050] The inclined perforated plate 43 makes the pressure change more gradual when the airflow passes through the vent 430 of the perforated plate 43, reducing the sudden changes in local high pressure and low pressure areas, thereby reducing energy loss, increasing flow rate, making the airflow more stable, and making it easier for the airflow to pass through the perforated plate 43.

[0051] Optionally, the rotating component 4 also includes a rotating rod 45 and a positioning rod 46. The rotating rod 45 is an L-shaped rod. The first end of the rotating rod 45 is inserted into one of the sub-sleeves 411 and connected to the sub-sleeve 411. The second end of the rotating rod 45 is located outside the housing 3, and the outer wall near the second end is opposite to the side wall of the housing 3. The middle part of the rotating rod 45 is rotatably connected to the housing 3.

[0052] The positioning rod 46 is located outside the housing 3, and one end is movably inserted into the outer wall of the rotating rod 45 near the second end. The positioning rod 46 can rotate with the rotating rod 45. The other end of the positioning rod 46 is used to be inserted into the housing 3 after the rotating rod 45 has finished rotating. The axial direction of the positioning rod 46 is the axial direction of the sleeve 41.

[0053] In the above implementation, the rotating rod 45 is used to rotate the sleeve 41. The positioning rod 46 is used to limit the rotating rod 45 to remain stationary within the housing 3.

[0054] For example, in order to facilitate the insertion of the positioning rod 46 into the housing 3, the side wall of the housing 3 has two positioning holes 30, which are located on the same straight line.

[0055] In use, when it is necessary to switch the positions of the first drying chamber 401 and the second drying chamber 402, the operator pulls the positioning rod 46 and gradually slides it out of the positioning hole 30 of the housing 3. Then, the rotating rod 45 is rotated, causing the partition 42 to rotate 180 degrees and stop. The rotation of the partition 42 causes the first drying chamber 401 and the second drying chamber 402 to rotate, thereby realizing the switching of the positions of the first drying chamber 401 and the second drying chamber 402. Then, the positioning rod 46 is inserted into the other positioning hole 30 to limit the rotation rod 45.

[0056] Optionally, an end plate 461 is connected to the end of the positioning rod 46 away from the housing 3. The rotating component 4 also includes a first elastic reset component 47, which is sleeved on the positioning rod 46 and has its two ends clamped between the end plate 461 and the end of the rotating rod 45, respectively. The first elastic reset component 47 is used to enable the positioning rod 46 to automatically reset after being pulled out of the positioning hole 30.

[0057] Figure 4 for Figure 1 A structural diagram of another state in the middle, combined with Figure 4 Optionally, the side wall of the box 3 near the bottom has a feed inlet 304, which is connected to the interior of the box 3. When the first drying chamber 401 is connected to the opening 300, the first drying chamber 401 is connected to the feed inlet 304. When the second drying chamber 402 is connected to the opening 300, the second drying chamber 402 is also connected to the feed inlet 304.

[0058] The distribution cabinet also includes a baffle assembly 5, which includes a baffle 51. The baffle 51 is movably located at the bottom of the enclosure 3 and connected to the enclosure 3. The baffle 51 is configured to block the opening 300 or open the opening 300.

[0059] In the above implementation, the baffle 51 is used to control whether the opening 300 is closed or open. When the first drying chamber 401 or the second drying chamber 402 is connected to the opening 300, and it is necessary to discharge the desiccant from the first drying chamber 401 or the second drying chamber 402, the baffle 51 can be moved away from the opening 300, so that the desiccant in the first drying chamber 401 or the second drying chamber 402 can slide out from the opening 300. The feed port 304 is used to refill the desiccant into the first drying chamber 401 or the second drying chamber 402. When it is necessary to refill the desiccant, the baffle 51 can be controlled to close the opening 300, and the desiccant can enter the first drying chamber 401 or the second drying chamber 402 along the feed port 304.

[0060] For example, the baffle 51 includes a U-shaped plate 511 and a limiting plate 512. The limiting plate 512 is located at one end of the U-shaped plate 511 along the axial direction of the fixed shaft 31 and is connected to the U-shaped plate 511. The top surface of the bottom of the U-shaped plate 511 is in contact with the bottom of the housing 32. The two side walls of the U-shaped plate 511 and the limiting plate 512 are in contact with the outer wall of the housing 32. In this way, the movement of the baffle 51 can be limited by the limiting plate 512 and the side walls of the U-shaped plate 511.

[0061] In this embodiment, the feed inlet 304 is provided with a feed pipe 3041. One end of the feed pipe 3041 is used to extend into the first drying chamber 401 or the second drying chamber 402 and contact one of the partitions 42. In this way, when the new desiccant enters the first drying chamber 401 or the second drying chamber 402 along the feed pipe 3041, it will flow along the inclined surface of the partition 42.

[0062] See you again Figure 1 Optionally, the baffle assembly 5 further includes a first slider 52 and a second elastic reset member 53. The first slider 52 is movably located in the side wall of the housing 3 and is connected to the baffle 51. The moving direction of the first slider 52 is the height direction of the housing 3.

[0063] The second elastic reset member 53 is located on one side of the first slider 52 along the moving direction of the first slider 52, and its two ends are respectively clamped between the first slider 52 and the inner wall of the housing 3. The extension and retraction direction of the second elastic reset member 53 is the same as the moving direction of the first slider 52.

[0064] In the above implementation, the first slider 52 is used to slide the baffle 51 in the housing 3, and the second elastic reset member 53 is used to re-drive the first slider 52 to reset after the baffle 51 moves, so that the baffle 51 can re-close the opening 300.

[0065] In use, pulling one end of the baffle 51 downwards causes the first slider 52 to move, compressing the second elastic reset member 53 and causing it to deform. The baffle 51 gradually moves away from the bottom opening 300 of the housing 3, releasing the seal on the opening. At this point, the desiccant gradually flows along the baffle 51 and is then discharged, thus achieving desiccant discharge. When the baffle 51 is released, the deformed second elastic reset member 53 causes the baffle 51 to move upwards, re-closing the opening 300 of the housing 3, thereby preventing the desiccant from discharging.

[0066] In this embodiment, to limit the movement of the first slider 52, a first groove is provided in the side wall of the housing 3, the length direction of the first groove being the height direction of the housing 3. The cross-section of the first groove is dovetail-shaped. Correspondingly, the first slider 52 is also a dovetail-shaped block structure. The first slider 52 is located in the first groove and slides in contact with the groove wall of the first groove.

[0067] For example, to improve the connection stability between the baffle 51 and the housing 3, there are multiple first sliding grooves. These multiple first sliding grooves are arranged at intervals around the perimeter of the baffle 51. Correspondingly, there are also multiple first sliders 52, each located in a corresponding first sliding groove.

[0068] Optionally, the distribution cabinet also includes a flow guiding assembly 6, which includes a flow guiding plate 61, a second slider 62, and a third elastic reset member 63. The flow guiding plate 61 is movably located on the side of the baffle 51 away from the housing 3, and is located at one end of the baffle 51 along the axis of the rotating member 4. The flow guiding plate 61 and the limiting plate 512 are located at the two ends of the U-shaped plate 511, respectively.

[0069] The second slider 62 is movably located at the bottom of the baffle 51 and connected to the guide plate 61. The moving direction of the second slider 62 is perpendicular to the moving direction of the first slider 52. The third elastic reset member 63 is located on one side of the second slider 62 along the moving direction of the second slider 62, and its two ends are respectively clamped between the second slider 62 and the baffle 51. The extension and retraction direction of the third elastic reset member 63 is the same as the moving direction of the second slider 62.

[0070] In the above implementation, the guide plate 61 is used to guide the desiccant discharged into the baffle 51. The second slider 62 is connected to the baffle 51, allowing the guide plate 61 to move relative to the baffle 51, thereby achieving the guiding effect. The third elastic reset member 63 is used to reset the guide plate 61 after it has moved.

[0071] In actual use, pulling the guide plate 61 moves it, causing the second slider 62 to move and compress the third elastic reset member 63, causing it to deform. Then, pressing down on the guide plate 61 causes it to move downwards. The guide plate 61, through the second slider 62, moves the baffle 51 downwards. The baffle 51, through the first slider 52, moves and compresses the second elastic reset member 53, causing it to deform. The baffle 51 gradually moves and separates from the opening 300, releasing the seal on the opening 300. At this time, the desiccant gradually flows along the baffle 51 and then flows along the baffle 51 to the top surface of the guide plate 61, thus achieving desiccant discharge. After the desiccant is discharged, releasing the guide plate 61 causes the deformed third elastic reset member 63 to push the guide plate 61 laterally through the second slider 62 to reset. The second elastic reset member 53, through the first slider 52, moves the baffle 51 upwards to close the opening 300 again. The baffle 51 then moves the second slider 62 upwards, and the second slider 62 moves the guide plate 61 upwards to reset.

[0072] Figure 5 for Figure 1 The main view, combined with Figure 5 Optionally, along the direction from one end of the baffle 51 where the guide vane 61 is located to the other end, the distance between the guide vane 61 and the baffle 51 gradually decreases, and the distance between the baffle 51 housings 3 also gradually decreases.

[0073] This allows the desiccant falling onto the guide plate 61 and the baffle 51 to flow along their top surfaces, thus facilitating desiccant collection.

[0074] For example, the angle of inclination of the side of the guide plate 61 facing the baffle 51 is greater than the angle of inclination of the side of the baffle 51 facing the housing 3, which can speed up the flow of the desiccant and facilitate the rapid outflow of the desiccant.

[0075] To facilitate control of the movement of the guide vane 61, a pull ring 64 is connected to one end of the guide vane 61 that protrudes outside the housing 3 along the axis of the fixed shaft 31. Pulling the pull ring 64 controls the translation of the guide vane 61. Pressing down the pull ring 64 causes the guide vane 61, along with the baffle 51, to move downwards.

[0076] In this embodiment, the first elastic reset member 47, the second elastic reset member 53, and the third elastic reset member 63 are all extension springs.

[0077] Figure 6 for Figure 5 The side view, combined with Figure 6 The guide plate 61 is also a U-shaped plate, with its bottom top surface fitting against the bottom surface of the baffle 51. This ensures close contact between the two, allowing the desiccant to be discharged along the bottom of both the baffle 51 and the guide plate 61.

[0078] In addition, to separate the cabinet 3 from the ground, the bottom of the cabinet 1 is provided with multiple support legs 11. One end of each support leg 11 is connected to the bottom of the cabinet 1, and the other end of the support leg 11 is used to place it on the ground. The cabinet 3 is located between the support legs 11.

[0079] In this embodiment of the present disclosure, the desiccant in the first drying chamber 401 and the second drying chamber 402 is activated carbon granules.

[0080] The following is a brief description of the operation of the power distribution cabinet provided in this embodiment: Due to varying operating environments, in humid environments, prolonged operation of the distribution cabinet can lead to the entry of humid air into the cabinet 1, affecting the normal operation of the electrical components inside. In such cases, the exhaust fan 21 is activated, drawing the humid air out of the cabinet 1. This humid air then travels along the exhaust duct 22 into the housing 3 and into the first drying chamber 401, where a desiccant dries the air. The dried air then re-enters the cabinet 1 through the air outlet 303, ensuring proper airflow and facilitating heat dissipation for the electrical components.

[0081] When the desiccant in the first drying chamber 401 becomes saturated with moisture after prolonged use and needs to be replaced, the operator pulls the positioning rod 46 to gradually slide it out of the positioning hole 30 in the housing 3. Then, the rotating rod 45 is rotated, causing the partition 42 to rotate 180 degrees and stop. The rotation of the partition 42 then causes the first drying chamber 401 and the second drying chamber 402 to rotate. After the positions of the first drying chamber 401 and the second drying chamber 402 are interchanged, the second drying chamber 402 containing the new desiccant rotates to the top and connects with the air inlet 302 and the air outlet 303. The first drying chamber 401, containing the moisture-saturated desiccant, rotates to the bottom and connects with the opening 300. Then, the positioning rod 46 is inserted again into another positioning hole 30 to limit the rotation rod 45. Next, when the desiccant in the saturated first drying chamber 401 rotates to the bottom, and it is necessary to remove the saturated desiccant, the operator pulls the guide plate 61 to move it. The guide plate 61 drives the second slider 62 to move and compress the third elastic reset member 63, causing it to deform. Then, the guide plate 61 is pressed down and moves downward. The guide plate 61 drives the baffle 51 to move downward through the second slider 62. The baffle 51 drives the first slider 52 to move and compress the second elastic reset member 53, causing it to deform. The baffle 51 gradually moves and separates from the opening 300, removing the seal on the opening 300. At this time, the desiccant gradually flows along the baffle 51 and then flows into the top surface of the guide plate 61, thus realizing the discharge of the desiccant. After the desiccant is discharged, the guide plate 61 is released. At this time, the deformed third elastic reset member 63 pushes the guide plate 61 to move laterally and reset via the second slider 62. The second elastic reset member 53 drives the baffle 51 to move upward via the first slider 52 to close the opening 300 again. The baffle 51 drives the second slider 62 to move upward, and the second slider 62 drives the guide plate 61 to move upward and reset. By repeating the above steps, the moisture in the chamber 3 can be dried alternately by the first drying chamber 401 and the second drying chamber 402.

[0082] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
