Description

Technical Field

[0001] This invention relates to the field of shore-based power distribution technology, and more specifically, to a marine shore-based variable frequency power container power distribution station. Background Technology

[0002] A search revealed a marine shore power containerized substation disclosed in publication number CN106253112A, comprising a container body with double doors at both ends along its length. The interior of the container body, along its length, is divided by partition walls into a cable winch box, a transformer box, and a power output box. Water-sealed doors are installed on the partition walls. The cable winch box contains a cable winch and a shore power combiner box, with the cable on the winch electrically connected to the shore power combiner box. A cable guide trolley is located at the bottom of the cable winch. The transformer box contains a transformer and a control cabinet. The power output box is further divided into a power supply box and a passageway on one side, both connected to a door at one end. This design improves the container's waterproofness, facilitates operation, ensures a relative balance of temperature and humidity within the container to withstand harsh external environments, and prevents corrosion of the equipment by polluting gases.

[0003] The aforementioned patents still have shortcomings in practical use. Although existing distribution boxes take into account the need for waterproofing and moisture protection, and ensure that the humidity inside the distribution station is maintained within a suitable range by installing air conditioners or dehumidifiers, the actual moisture protection problem faced by distribution stations set up in coastal areas such as ships is more complex and serious. Distribution stations set up in coastal areas not only have to face the air environment with higher humidity, but also have to face the fact that the temperature change of the ocean is relatively slower than that of the distribution station body due to the ocean's higher specific heat capacity. The sea surface temperature changes lag behind the ambient air temperature. At night, the heat stored on the sea surface is released, forming warm and humid sea breezes. When the warm and humid airflow comes into contact with the cooled metal walls of the container, it is very easy to cause condensation inside.

[0004] In existing power distribution stations, dehumidifiers are mostly fixed installations. The equipment inside the enclosures is densely packed and the space is long and narrow. Relying solely on the dehumidifier's own fan to create local airflow circulation, dead air zones easily form in remote areas, behind the cabinet, and in the corners of the enclosure. High-humidity air cannot effectively flow through the dehumidifier, resulting in localized high humidity, which can easily lead to problems such as condensation, corrosion, and insulation degradation. Simply increasing the dehumidifier's power cannot fundamentally solve the problem of uniform dehumidification. On the other hand, during the day-night transition, the dehumidifier's own dehumidification efficiency is insufficient to quickly resolve the condensation problem caused by the high humidity of the sea breeze, leading to condensation on the cabinet and posing a safety hazard.

[0005] Therefore, it is urgent to introduce a moisture-proof and dehumidification protection mechanism suitable for coastal climates. In addition to ordinary moisture-proof measures, targeted solutions specific to coastal climates should be added to ensure the safe operation of substations even under the influence of high-humidity sea breezes through dehumidification. Existing substations used in coastal areas have the following problems: First, there are dehumidification dead zones. The narrow and crowded interior of the substation prevents high-humidity air from effectively flowing through the dehumidification equipment, resulting in localized high-humidity spots. Second, the problem of condensation during day and night transitions cannot be solved. When large amounts of warm, humid sea air enter the enclosure, they easily condense on the low-temperature inner walls, cabinets, and copper busbars, leading to safety hazards.

[0006] Based on this, the present invention discloses a marine shore-based variable frequency power container distribution station. Summary of the Invention

[0007] To address the problem mentioned in the background art that existing power distribution stations have dehumidification dead zones, resulting in localized high humidity points and easy surface condensation during day and night transitions, thus posing safety hazards, there is an urgent need to construct a dehumidification and moisture-proof protection mechanism that combines comprehensive ventilation and circulation dehumidification with the prevention of condensation, providing reliable safety assurance when used in coastal areas. This invention provides a marine shore-based variable frequency power container power distribution station, which includes a container body and a hatch. The container body is equipped with an inspection door, a cabinet is installed inside the container body, and a temperature and humidity sensor is installed on the container body. Mounting plates are symmetrically fixedly installed on the top wall inside the container body. Reciprocating screws are fixedly installed between the mounting plates, and guide rods are fixedly installed between the mounting plates. Mounting frames are slidably installed on the guide rods. A matching sliding sleeve is rotatably fitted on the reciprocating screw, and the sliding sleeve is rotatably connected to the mounting frame. A servo motor is fixedly installed on the mounting frame, and a drive gear is fixedly installed at the output end of the servo motor. A gear ring that meshes with the drive gear is fixedly fitted on the sliding sleeve. A condensing dehumidifier is installed at the bottom of the mounting frame. The condensing dehumidifier is equipped with a power supply mechanism, a drainage mechanism, an automatic opening and closing component on the mounting bracket, and a ventilation component on the inspection door. The automatic opening and closing component includes a folding door that slides on the cabinet, a mounting block that is fixedly installed on the top of the folding door, a claw on the mounting block, and an operating arm on the mounting frame. The ventilation components include louvers symmetrically positioned on the access door.

[0008] Based on this, since the power supply line can be dragged around when the condenser dehumidifier is moved, which increases the risk of accidents in crowded and complex substations, in order to achieve stable and continuous power supply under clean conditions, the power supply mechanism includes a wire box fixedly mounted on the mounting plate. A rotating shaft is rotatably mounted inside the wire box. A torsion spring is fixedly mounted between the rotating shaft and the wire box. An opening is provided on the wire box. A power supply line is fixedly mounted on the rotating shaft. The other end of the power supply line extends out of the opening and is electrically connected to a servo motor.

[0009] Based on this, since the condenser dehumidifier produces condensate water during operation, in order to drain the condensate water and prevent moisture backflow, the drainage mechanism includes a water collection box fixedly installed at the bottom of the condenser dehumidifier. The bottom surface of the water collection box is inclined. A drain column connected to the outside of the container body is fixedly installed at one end of the bottom wall of the container body. The side wall of the water collection box near the drain column is higher than the other end. A self-sealing quick-connect female connector is provided at the top of the drain column opposite to the water collection box. A self-sealing quick-connect male connector adapted to the self-sealing quick-connect female connector is provided on the water collection box.

[0010] In another embodiment, since the cabinet needs to be sealed to improve security, it may lead to insufficient internal air circulation and inability to achieve rapid dehumidification when needed. To achieve efficient dehumidification inside the cabinet, the automatic opening and closing assembly also includes three mounting arms fixedly installed on the mounting frame. A U-shaped frame is fixedly installed on the mounting arm, and a rotating column is rotatably installed on the U-shaped frame. The rotating column and the pawl are arranged on the same vertical plane. A connecting rod is fixedly installed at the bottom of the rotating column, and the operating arm is rotatably connected to the bottom of the connecting rod. A limit plate is fixedly installed on the operating arm, and a mounting column is fixedly installed on the mounting block. The pawl is rotatably connected to the mounting column, and a torsion spring is fixedly installed between the pawl and the mounting block. A linkage mechanism is provided on the rotating column.

[0011] Based on this, since the opening and closing need to be coordinated with the movement of the condensing dehumidifier, in order to achieve automatic and reasonable effective opening and closing in accordance with its movement mode, the linkage mechanism includes a rotating rod rotatably mounted on the mounting arm, a bushing fitted on the rotating rod, and friction transmission between the bushing and the rotating rod. A synchronous belt is fitted between the bushing and the output end of the servo motor. A guide thread is provided at one end of the rotating rod between the two mounting arms. A sliding plate is slidably fitted on the rotating rod. A baffle adapted to the sliding plate is fixedly installed between the two mounting arms. A rack is fixedly installed on the sliding plate. A half gear meshing with the rack is fixedly fitted on the rotating column. A decondensation component is provided on the rotating rod.

[0012] As a further improvement to this technical solution, the decondensation component includes several downwardly inclined condensation guide plates fixedly installed in a linear array inside the cabinet. The cabinet is hinged with an isolation door panel adapted to the condensation guide plates, and the condensation guide plates extend out of the isolation door panel. The folding door is located on the outside of the isolation door panel. The condensation guide plate is made of galvanized sheet metal and has condensation guide grooves. Based on this, since condensate droplets are difficult to remove due to their small surface area, in order to accelerate the dehumidification effect, the decondensation component also includes a winding rod fixedly installed at both ends of the rotating rod extending from the mounting arm. A protective cover adapted to the winding rod is fixedly installed on the mounting arm. A rotary joint is fixedly installed on one of the winding rods. A connecting pipe is fixedly installed between the exhaust end of the condensing dehumidifier and the end of the rotary joint extending from the protective cover. An air guide pipe is fixedly installed at the interface of the rotary joint near the inner side of the protective cover. Several air outlet pipes adapted to the condensate guide plate are fixedly installed on the air guide pipe. The opening direction of the air outlet pipes faces the outside of the cabinet opening. Another winding rod is fixedly installed with a connecting rope, and several water-absorbing strips adapted to the condensation guide plate are fixedly installed on the connecting rope. A drying tube is fixedly installed between the exhaust end of the condensation dehumidifier and the protective cover corresponding to one side of the water-absorbing strip, and the drying tube extends into the protective cover.

[0013] As a further improvement to this technical solution, a guide rail corresponding to the winding rod is fixedly installed on the inner bottom wall of the container body. Two T-blocks are slidably installed inside the guide rail. A magnet is fixedly installed on the top of the T-block, and the magnetic poles of the two magnets are arranged in opposite directions. Magnetic plates are fixedly installed at the bottom of the air duct and the bottom of the connecting rope, and the magnetic poles of the two magnetic plates are arranged in opposite directions.

[0014] In another solution, due to the high degree of variability and complexity of the external environment, a single ventilation strategy cannot meet the usage requirements under actual complex conditions. In order to adopt different ventilation strategies in suitable environments, the ventilation component also includes a slide rail fixedly installed on the inner wall of the inspection door. Two sealing plates adapted to the louvers are slidably installed in the slide rail. Sealing strips are fixedly installed on both sides of the sealing plates, and a driving device is provided on the sealing plates.

[0015] As a further improvement to this technical solution, the driving device includes two fixed plates symmetrically fixedly installed on the inner wall of the inspection door, a driving rod rotatably installed between the two fixed plates, and a guide thread with opposite directions symmetrically opened on the driving rod. A slider adapted to the guide thread is fixedly installed on the sealing plate. A motor box is fixedly installed on the inspection door, and a drive motor is fixedly installed inside the motor box. A transmission belt is fitted between the output end of the drive motor and the driving rod. A limiting strip adapted to the sealing plate is fixedly installed on the slide rail.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this type of marine shore-based variable frequency power container substation, a servo motor is set up to drive a large gear ring through a small gear to reduce torque, thereby driving the dehumidifier to move slowly back and forth along the guide rod, eliminating dehumidification dead zones. The gear speed reduction ensures slow movement, so that the air at each point is fully dehumidified, avoiding the formation of dead zones due to insufficient dehumidification of the air at a distance caused by excessively fast movement. At the same time, driving a large load with low power can effectively reduce energy consumption.

[0017] 2. In this type of marine shore-based variable frequency power container substation, a servo motor drives a rack and pinion mechanism via a synchronous belt. When rotating forward, the operating arm flips open the door and releases the air duct and water suction strip. When rotating in reverse, the door automatically closes and retracts. The condensation plate is made of galvanized thin plate for active pre-condensation and dehumidification. It works in conjunction with the high-temperature gas generated by the condenser dehumidifier for dehumidification and drying. The magnetic absorbing sheet and the opposite pole magnet are precisely aligned and can automatically separate when encountering obstacles.

[0018] 3. In this type of marine shore-based variable frequency power container substation, a torsion spring is installed inside the conductor box. When the dehumidifier is moved far away, the power supply line is automatically released, and when it is moved nearby, the torsion spring is wound up. The cable is always suspended from the top and does not drag on the ground, avoiding snagging and bending, keeping the inside of the box clean. The bottom of the water collection box is inclined and has a self-sealing quick-connect male connector at the bottom, which cooperates with the self-sealing quick-connect female connector on the drain column. When moved, it automatically seals to prevent moisture backflow, and when returned to its position, it automatically connects to drain condensate. No manual intervention is required throughout the process, ensuring no leakage and no backflow.

[0019] 4. In this type of marine shore-based variable frequency power container substation, louvers are installed, and sliding rails and sealing plates are installed on the inner wall. Sealing strips are installed on both sides of the sealing plates. The drive motor drives the reverse-threaded drive rod to drive the two sealing plates to slide away from each other, completely sealing the louvers and isolating them from the intrusion of high humidity sea winds. When the outside is dry or the internal humidity is high, the sealing plates retract and open the louvers to promote ventilation and heat dissipation, realizing the switching between isolation and ventilation as needed, and effectively avoiding the risk of condensation caused by the temperature difference between day and night.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Existing power distribution stations have dehumidification dead zones, resulting in localized high humidity points and easy surface condensation during day and night transitions, which in turn poses safety hazards. There is an urgent need to build a dehumidification and moisture-proof protection mechanism that combines comprehensive ventilation and circulation dehumidification with the prevention of condensation, so as to provide reliable safety assurance when used in coastal areas.

[0024] Therefore, this invention provides a marine shore-based variable frequency power containerized substation. (See below) Figures 1-10 As shown, it includes a container body 1 and a hatch 2. The container body 1 is equipped with an inspection door 3. The container body 1 is equipped with a cabinet 4. The container body 1 is equipped with a temperature and humidity sensor. The container body 1 is symmetrically fixedly installed on the top wall of the container body 1. The reciprocating screw 51 is fixedly installed between the mounting plates 5. The guide rod 52 is fixedly installed between the mounting plates 5. The mounting bracket 53 is slidably installed on the guide rod 52. The reciprocating screw 51 is rotatably fitted with a matching sliding sleeve 54. The sliding sleeve 54 is rotatably connected to the mounting bracket 53. The mounting bracket 53 is fixedly installed with a servo motor 55. The output end of the servo motor 55 is fixedly installed with a drive gear 56. The sliding sleeve 54 is fixedly fitted with a gear ring 57 that meshes with the drive gear 56. The bottom of the mounting bracket 53 is equipped with a condenser dehumidifier 58. The condenser dehumidifier 58 is equipped with a power supply mechanism, a drainage mechanism, an automatic opening and closing component 6 on the mounting bracket 53, and a ventilation component on the inspection door 3. The automatic opening and closing component 6 includes a folding door 44 that is slidably installed on the cabinet 4. A mounting block 66 is fixedly installed on the top of the folding door 44. A claw 69 is provided on the mounting block 66. An operating arm 65 is provided on the mounting frame 53. The ventilation components include louvers 31 symmetrically arranged on the access door 3.

[0025] When a containerized dehumidifier station is installed in a coastal area, it can use the monitoring results of temperature and humidity sensors to dehumidify the container when the humidity is low by using a fixed condenser dehumidifier 58. When the humidity reaches a threshold, the servo motor 55 is activated as needed, driving the gear ring 57 to rotate via the drive gear 56, which in turn drives the sliding sleeve 54 to rotate. When the sliding sleeve 54 rotates, it drives the mounting frame 53 to move horizontally under the guidance of the reciprocating screw 51, thereby causing the condenser dehumidifier 58 to reciprocate within the container body 1, thus achieving mobile dehumidification. This avoids the dehumidification dead zones caused by the dehumidifier being installed in a fixed position, and allows for comprehensive dehumidification of the interior space of the container body 1. Furthermore, by using a small gear to drive a large gear, the driving torque can be increased, thereby driving the condenser dehumidifier 58 to move and effectively saving output power. On the other hand, the speed can be reduced through the gear ratio, thus enabling the condenser dehumidifier 58 to slowly reciprocate along the guide rod 52. By controlling the slow movement of the condenser dehumidifier 58, its dehumidification effect on the adjacent space can be improved, avoiding insufficient gas absorption caused by excessively fast movement. If the movement is too fast, the air at the far end will not be dehumidified before it moves to another position. Even if the condenser dehumidifier 58 moves back and forth in the container body 1, it cannot fully dehumidify the air at the far end each time it reaches that position, thus failing to eliminate dehumidification dead zones. By controlling the movement speed, the dehumidification process at each point is ensured to be fully effective, eliminating dehumidification dead zones. The louvers 31 can circulate and replace the air in the container body 1. Through the automatic opening and closing component 6, when the humidity is not high, the folding door 44 can be closed by operating the claw 69 through the operating arm 65, thereby protecting the electrical equipment. When the humidity is high, the folding door 44 can be opened by operating the claw 69 through the operating arm 65, thereby allowing the condenser dehumidifier 58 to dry and dehumidify the air in the cabinet 4 better and faster.

[0026] Further, see Figure 7 and Figure 12 As shown, the power supply mechanism includes a wire box 551 fixedly mounted on the mounting plate 5. A rotating shaft 552 is rotatably mounted inside the wire box 551. A torsion spring 553 is fixedly mounted between the rotating shaft 552 and the wire box 551. An opening 554 is provided on the wire box 551. A power supply line 555 is fixedly mounted on the rotating shaft 552. The other end of the power supply line 555 extends out of the opening 554 and is electrically connected to the servo motor 55.

[0027] During reciprocating dehumidification, the movement of the mounting frame 53 drives the servo motor 55 to reciprocate. Given the crowded and complex space within the substation, the power supply cable 555 is wound up inside the junction box 551. When the servo motor 55 moves to the far end, it can pull the power supply cable 555 to extend and drive the rotating shaft 552 to rotate, thus achieving a stable power supply following effect. When the servo motor 55 moves to the near end, the torsion spring 553 can drive the rotating shaft 552 to rotate and reset, winding up the power supply cable 555. This avoids the power supply cable 555 being dragged arbitrarily within the container body 1 to ensure smooth reciprocating motion. It also prevents the power supply cable 555 from being hindered or bent by obstacles, thus preventing it from affecting the movement of the mounting frame 53. Furthermore, it keeps the space inside the container body 1 neat and orderly, ensuring that the power supply cable 555 is wound up at the top, without obstructing the entry and exit of maintenance personnel.

[0028] Furthermore, see Figure 5 , Figure 8 and Figure 13 As shown, the drainage mechanism includes a water collection box 581 fixedly installed at the bottom of the condenser dehumidifier 58. The bottom surface of the water collection box 581 is inclined. A drain column 583 connected to the outside of the container body 1 is fixedly installed at one end of the inner bottom wall. The side wall of the water collection box 581 near the drain column 583 is higher than the other end. A self-sealing quick-connect female connector 584 is provided at the top of the drain column 583 opposite to the water collection box 581. A self-sealing quick-connect male connector 582 adapted to the self-sealing quick-connect female connector 584 is provided on the water collection box 581.

[0029] When the condenser dehumidifier 58 is working, the condensate generated from the air is collected in the water collection box 581. The water collection box 581 is not connected to the container body 1, thus preventing water from evaporating back into the container body 1. The water collection box 581 is connected to the drain column 583 through a self-sealing quick-connect device. When the condenser dehumidifier 58 moves away from the drain column 583, the self-sealing quick-connect male connector 582 and the self-sealing quick-connect female connector 584 self-seale to close the water collection box 581 and the drain column 583. When the condenser dehumidifier 58 completes one cycle, the water collection box 581 and the drain column 583 are connected through the self-sealing quick-connect male connector 582 and the self-sealing quick-connect female connector 584. The two are connected and quickly discharge the condensate in the water collection box 581 into the container body 1 through the drain column 583. The inclined bottom surface of the water collection box 581 allows the collected condensate to move towards the self-sealing quick-connect male connector 582 under the action of gravity. It should be noted that the working principle and usage of self-sealing quick couplings are based on existing mature technologies, such as CPC quick couplings (e.g., MJ CPC quick couplings QC4108 / QC6108, QC0040 / QC0060, etc.). By using lock-free male and female stop connectors, the water collection box 581 and drain column 583 can be self-sealed, and the condensate can be automatically and periodically discharged as the condenser dehumidifier 58 moves, preventing moisture backflow.

[0030] For details, see Figure 6 , Figure 7 and Figures 9-10 As shown, the automatic opening and closing assembly 6 also includes three mounting arms 61 fixedly mounted on the mounting frame 53. A U-shaped frame 62 is fixedly mounted on the mounting arm 61, and a rotating column 63 is rotatably mounted on the U-shaped frame 62. The rotating column 63 and the pawl 69 are arranged on the same vertical plane. A connecting rod 64 is fixedly mounted at the bottom of the rotating column 63. An operating arm 65 is rotatably connected to the bottom of the connecting rod 64. A limit plate 651 is fixedly mounted on the operating arm 65. A mounting column 67 is fixedly mounted on the mounting block 66. The pawl 69 is rotatably connected to the mounting column 67. A torsion spring 68 is fixedly mounted between the pawl 69 and the mounting block 66. A linkage mechanism is provided on the rotating column 63. The linkage mechanism includes a rotating rod 631 rotatably mounted on the mounting arm 61. A bushing is fitted on the rotating rod 631, and the bushing and the rotating rod 631 are driven by friction. A synchronous belt 632 is fitted between the bushing and the output end of the servo motor 55. A guide thread 633 is provided on one end of the rotating rod 631 between the two mounting arms 61. A sliding plate 634 is slidably fitted on the rotating rod 631. A baffle 635 adapted to the sliding plate 634 is fixedly installed between the two mounting arms 61. A rack 636 is fixedly installed on the sliding plate 634. A half gear 637 that meshes with the rack 636 is fixedly fitted on the rotating column 63. A dew removal component is provided on the rotating rod 631.

[0031] During operation, as the servo motor 55 drives the condenser dehumidifier 58 to reciprocate, the synchronous belt 632 drives the rotating rod 631 to rotate. This, in turn, drives the sliding plate 634 to move to the other end under the guidance of the baffle 635 via the guide thread 633. Simultaneously, the sliding plate 634 moves, causing the rack 636 to move and the half-gear 637 to rotate half a revolution. This drives the rotating column 63 to rotate half a revolution, reversing the clearance direction of the operating arm 65. After half a revolution, the sliding plate 634 is limited by the mounting arm 61, and the bushing and rotating rod 631 are connected by frictional transmission through the contact surface. This limitation causes the rotating rod 631 to slip and rotate freely between the bushing, achieving a frictional clutch effect. At this point, the operating arm 65 is fixed and, as it moves with the condenser dehumidifier 58 towards the side where the folding door 44 is opened, engages with the pawl 69 at the limiting plate. Under the action of 651, the operating arm 65 maintains a vertical posture. Since the force required for the folding door 44 to move is less than the force required for the second torsion spring 68 to undergo a large deformation, the operating arm 65 will drive the folding door 44 to slide open. After the folding door 44 is fully opened, when the operating arm 65 moves forward with the condenser dehumidifier 58, the pawl 69 will rotate along the mounting column 67, thereby causing the operating arm 65 to separate from the pawl 69. After separation, the pawl 69 will reset under the action of the second torsion spring 68, and the operating arm 65 will continue to move until it engages with the next pawl 69. When the operating arm 65 moves in the opposite direction with the condenser dehumidifier 58, under the fixing action of the second torsion spring 68 on the pawl 69, and because the force of the operating arm 65 rotation is less than the friction of the folding door 44, the pawl 69 will drive the operating arm 65 to rotate along the connecting rod 64, thereby maintaining the open state of the folding door 44 throughout the entire dehumidification process. When the servo motor 55 is driven in reverse, the synchronous belt 632 drives the rotating rod 631 to rotate in reverse, drives the sliding plate 634 to move in reverse, and drives the rotating column 63 to rotate in reverse half a turn through the rack 636. At this time, when the condensing dehumidifier 58 moves to the side where the folding door 44 is open, since the limiting direction of the limiting plate 651 is opposite to that before, the operating arm 65 will not drive the pawl 69 to open the folding door 44, but will drive the pawl 69 to close the folding door 44, thereby achieving automatic closing of the folding door 44. Moreover, the synchronous belt 632 transmission is faster than the transmission of the drive gear 56 and the gear ring 57, and can complete the rotation of the operating arm 65 within a small distance of the movement of the condensing dehumidifier 58, which can ensure that it is in the correct posture when in contact with the pawl 69. The opening and closing of the folding door 44 is controlled by controlling the rotation of the servo motor 55. Combined with the monitoring results of the temperature and humidity sensor, when there is a large temperature difference between inside and outside and the humidity of the sea breeze is high, the forward rotation of the servo motor 55 realizes the automatic opening of the folding door 44, which improves the dehumidification efficiency inside the cabinet 4. When the humidity is high but the internal and external temperatures are stable, the reverse rotation of the servo motor 55 can realize reciprocating dehumidification in the closed state of the folding door 44, which can better protect the electrical components from the outside world and improve safety.

[0032] Specifically, refer to Figures 6-8 and Figure 11 As shown, the decondensation component includes several downwardly inclined condensation guide plates 41 fixedly installed in a linear array inside the cabinet 4. An isolation door 43 adapted to the condensation guide plates 41 is hinged inside the cabinet 4, and the condensation guide plates 41 extend out of the isolation door 43. A folding door 44 is located outside the isolation door 43. Among them, the condensation guide plate 41 is made of galvanized sheet, and the condensation guide plate 41 is provided with condensation guide groove 42; The decondensation assembly also includes a winding rod 71 fixedly installed at both ends of the rotating rod 631 extending from the mounting arm 61. A protective cover 7 adapted to the winding rod 71 is fixedly installed on the mounting arm 61. A rotary joint 72 is fixedly installed on one of the winding rods 71. A connecting pipe 73 is fixedly installed between the exhaust end of the condensing dehumidifier 58 and the end of the rotary joint 72 extending from the protective cover 7. An air guide pipe 74 is fixedly installed at the interface of the rotary joint 72 near the inner side of the protective cover 7. Several air outlet pipes 75 adapted to the condensation guide plate 41 are fixedly installed on the air guide pipe 74. The opening direction of the air outlet pipes 75 faces the outside of the opening of the cabinet 4. A connecting rope 76 is fixedly installed on another winding rod 71. Several water-absorbing strips 77 that are compatible with the condenser plate 41 are fixedly installed on the connecting rope 76. A drying tube 78 is fixedly installed between the exhaust end of the condenser dehumidifier 58 and the protective cover 7 corresponding to one side of the water-absorbing strip 77, and the drying tube 78 extends into the protective cover 7. A guide rail 8 corresponding to the winding rod 71 is fixedly installed on the inner bottom wall of the container body 1. Two T-blocks 81 are slidably installed inside the guide rail 8. A magnet 82 is fixedly installed on the top of the T-block 81, and the magnetic poles of the two magnets 82 are set in opposite directions. Magnetic plates 83 are fixedly installed at the bottom of the air duct 74 and the bottom of the connecting rope 76, and the magnetic poles of the two magnetic plates 83 are set in opposite directions.

[0033] In actual operation, at points where condensation is prone to occur during the day-night transition, the servo motor 55 rotates forward, driving the folding door 44 to open. This improves dehumidification efficiency. Simultaneously, the rotating rod 631 rotates, driving the winding rod 71 to release the wound air pipe 74 and connecting rope 76. When the air pipe 74 and connecting rope 76 are released to the bottom, the magnetic attraction of the magnetic sheet 83 and magnet 82 straightens the connecting rope 76 and air pipe 74. Simultaneously, as the condenser dehumidifier 58 moves, the T-shaped block 81 moves synchronously along the guide rail 8, ensuring that the straightened connecting rope 76 and air pipe 74 are in a suitable position corresponding to the condenser plate 41. The condensed water droplets on the condenser plate 41 are blown outward through the air outlet pipe 75. By dispersing the condensed water droplets and increasing the evaporation area, dehumidification efficiency is accelerated, and it also prevents water droplets from dripping onto electrical components and causing short circuits or other safety hazards. At the same time, residual moisture is wiped away by the absorbent strip 77, and the heated dry gas after condensation dehumidification is used to further dehumidify the air. Gas is introduced into the air guide pipe 74 through the rotary joint 72 via the connecting pipe 73. Dry gas is used to blow away the condensate droplets. On the other hand, gas is guided into the protective cover 7 through the drying pipe 78 to dry the water absorption strip 77 with hot air. After a long period of overnight rest, the temperature of the box will eventually reach equilibrium with the temperature of the sea breeze environment. At this time, the risk of condensation is reduced. The folding door 44 can be closed by reversing the servo motor 55. At the same time, the rotating rod 631 reverses and drives the connecting rope 76 and the air guide pipe 74 to rewind back into the protective cover 7. At this time, the drying pipe 78 can quickly dry the water absorption strip 77 with hot air. The sliding plate 634 limits the rotation of the rotating column 63 and can also limit the winding and release at the same time. By setting the state when the winding and release are completed to the same number of rotations of the rotating rod 631 required for the rotating column 63 to rotate half a revolution, the synchronous belt 632 can slide relative to each other at the same time as the winding and release are completed, which can ensure the stability of the winding and release posture. By setting up a large area of ​​galvanized sheet, and utilizing the principle of low specific heat capacity and fast cooling, humid air is made to preferentially contact the condensation guide plate 41 to generate condensate, thereby reducing air humidity and reducing the probability of condensation on copper wires and other components inside the cabinet 4. Furthermore, the condensation guide groove 42 and the condensation guide plate 41 are set at an angle to guide the condensate to the outside of the cabinet 4, making it easier for the water suction strip 77 and the air outlet pipe 75 to remove the liquid. The isolation door plate 43 can allow liquid to pass through while avoiding the risk of liquid being brought into the cabinet 4 during blowing and wiping, thus improving safety. By setting the magnetic properties to opposite, it can be ensured that the magnetic pieces 83 on the connecting rope 76 and the air duct 74 can only be attracted to specific magnets 82, and will be repelled by another magnet 82 with opposite magnetic properties. Therefore, the connection sequence of the connecting rope 76 and the air duct 74 to the two T-blocks 81 is guaranteed, and they are straightened by magnetic attraction. The magnetic attraction fixation can automatically separate when the connecting rope 76 or the air duct 74 encounters obstruction, avoiding traction jamming that would cause abnormal operation of the condenser dehumidifier 58. After the obstruction is removed, the magnetic attraction can automatically reconnect.

[0034] More specifically, refer to Figures 1-4 As shown, the ventilation assembly also includes a slide rail 32 fixedly installed on the inner wall of the inspection door 3. Two sealing plates 33 adapted to the louvers 31 are slidably installed in the slide rail 32. Sealing strips 34 are fixedly installed on both sides of the sealing plates 33. A driving device is provided on the sealing plates 33. The drive device includes two fixed plates 35 symmetrically fixedly installed on the inner wall of the inspection door 3. A drive rod 36 is rotatably installed between the two fixed plates 35. The drive rod 36 is symmetrically provided with guide threads 37 in opposite directions. A slider 38 adapted to the guide thread 37 is fixedly installed on the sealing plate 33. A motor box 39 is fixedly installed on the inspection door 3. A drive motor 310 is fixedly installed inside the motor box 39. A transmission belt 311 is fitted between the output end of the drive motor 310 and the drive rod 36. A limit strip 312 adapted to the sealing plate 33 is fixedly installed on the slide rail 32.

[0035] During operation, when the external humidity is detected to be significantly higher than the humidity inside the container body 1, such as during rainy weather or the transition between day and night, the drive motor 310 can be started to rotate the drive rod 36. This, in turn, drives the two sealing plates 33 to move away from each other through the reverse guide threads 37 on both sides, and slides them along the slide rail 32 to the position corresponding to the louver 31. The louver 31 is then limited by the limiting strip 312. At this time, under the action of the sealing plate 33 and the sealing strip 34, the louver 31 is sealed, which can prevent external humid gas from entering the container body 1, thereby preventing the humidity inside the container body 1 from rising. It can also further prevent condensation by blocking the higher-temperature sea breeze during the transition between day and night. After the outside air temperature drops, the louver 31 can be opened for ventilation. When the outside air is dry or the internal humidity is high, the louver 31 can be opened for ventilation to simultaneously improve the heat dissipation and dehumidification effect of the power distribution station.

[0036] In summary, this solution uses gear reduction to drive the dehumidifier in reciprocating motion, eliminating dehumidification dead zones. The wiring box 551 uses a torsion spring to automatically retract and extend the power supply cable 555. The self-sealing quick-connect achieves automatic drainage and backflow prevention during movement. The synchronous belt 632 links the rack 636 and half gear 637. Forward rotation opens the door and releases the air duct 74 and water absorption strip 77 to blow away and wipe the condensate guide plate 41. Reverse rotation closes the door and retracts the dehumidifier. Multiple protections prevent the risk of short circuits caused by condensation. The louvers 31 are equipped with sealing plates 33, allowing for different ventilation strategies as needed. It is highly reliable with zero manual intervention and is suitable for long-term unattended operation in high-humidity coastal environments.
