Cabinet 1 The connecting rod 602 is rotatably connected via a rotating shaft 601. There are two rotating shafts 601 and two connecting rods 602, which are arranged parallel to each other. The two rotating shafts 601 are respectively installed at the upper and lower ends of the two connecting rods 602. The lower rotating shaft 601 is rotatably connected to the top surface of the partition 5. The two rotating shafts 601 are located at the upper and lower parts of the adjusting rod 603 on one side. The two rotating shafts 601, the connecting rods 602, and the adjusting rod 603 are arranged in a "U" shape. A row of positioning folding plates 604 is provided on the adjusting rod 603. A vertical rod 605 is slidably fitted on the positioning folding plate 604. A row of slots 606 is provided on the vertical rod 605. A cable tray 607 is locked inside the slots 606. The connection between the positioning folding plate 604 and the adjusting rod 603 is... The cable tray 607 is arranged in a "Z"-shaped bend. A gap exists between a row of positioning folding plates 604. One side of the upright 605 has a bent plate matching the shape of the positioning folding plates 604. The upright 605 is positioned by the bent plate, and the two plates 604 are nested together, allowing the upright 605 to slide smoothly along the length of the latter. The inner wall of the upright 605 slides against the positioning folding plates 604. The bottom surface of the slot 606 has a downward-facing groove. The bottom end of the cable tray 607 abuts against the groove. An extension block is provided at the contact end of the cable tray 607 and the groove, limiting and fixing the cable tray 607 and restricting its sway. A gap exists between the top of the cable tray 607 and the top surface of the slot 606, the height of which matches the height of the groove.One side of the adjusting rod 603 is threaded with a fixing bolt 608. There are four uprights 605, which are arranged in pairs and slidably fitted onto two adjusting rods 603. The cable tray 607 is respectively snapped into the slots 606 on the two corresponding uprights 605. The adjusting rod 603 away from the rotating shaft 601 has a threaded hole in the middle. One end of the fixing bolt 608 passes through the threaded hole and is threaded onto the back panel of the cabinet 1. A guide plate 7 is provided on the bottom surface inside the cabinet 1. A water-absorbing resin layer 8 is provided in the middle of the guide plate 7. The top surface of the water-absorbing resin layer 8 is covered with... The cover is equipped with a breathable and waterproof membrane 9. The cross-section of the guide plate 7 is trapezoidal, and the two side plates of the guide plate 7 are inclined downwards. Drainage holes are opened through the ends of the side plates that abut against the side wall of the cabinet 1. One-way valves are installed at the drainage holes to effectively prevent splashing from sea waves or backflow of humid air from the cabin during ship navigation. A placement groove is opened in the middle of the guide plate 7, and a water-absorbing resin layer 8 is laid in the placement groove. The water-absorbing resin layer 8 is made of sodium polyacrylate-based super absorbent resin. The breathable and waterproof membrane 9 is heat-fused to the top opening of the placement groove. The breathable and waterproof membrane 9 can be of model KT890DB+PE.

[0025] First, connect the power supply to the electrical equipment in this device, place the device in the designated working position, close the cabinet door 2 with hinges, start the fan 3, and exhaust hot air to the outside of the cabinet through the vent. External air enters the cabinet 1 from below or other ventilation areas after being filtered by the dust screen, forming air convection for heat dissipation. The partition 5 slides in the slide groove 4 through the end blocks, and can be disassembled and installed as needed, thereby placing and installing electrical components in the control cabinet. The adjusting rod 603 changes its rotation angle with the connecting rod 602, which facilitates the maintenance and installation of electrical components installed on the mounting assembly 6. When the positioning folding plate 604 moves synchronously with the adjusting rod 603, the upright 605 slides along the vertical section of the positioning folding plate through the matching bending plate on the side, realizing the position adjustment of the upright 605 in the height direction of the cabinet 1. The slot 606 on the upright 605 has an opening at the bottom surface that locks the bottom end of the cable tray 607, and the top gap facilitates the disassembly and replacement of the cable tray 607 as needed. Then, the required electrical components are installed on the mounting assembly 6 as needed. When the mounting assembly 6 is adjusted to the target position... After adjusting the height and level, tighten the fixing bolt 608 so that it passes through the threaded hole in the middle of the adjusting rod 603 and is secured to the back panel of the cabinet 1. Condensate generated inside the cabinet 1 due to heat exchange collects on both sides of the trapezoidal slope of the guide plate 7. Because the two side plates of the guide plate 7 are inclined downwards and have one-way valves installed at the drain holes at the ends that contact the side walls of the cabinet 1, it effectively prevents splashing from waves or backflow of humid air from the cabin during ship navigation. The salt-containing condensate flows rapidly along the slope of the guide plate 7 to the drain holes and is discharged outside the cabinet. Any trace amounts not discharged in time... Moisture is absorbed by the water-absorbing resin layer 8 in the central placement tank. The breathable and waterproof membrane 9 covering its top surface allows moisture to pass through while preventing liquid from entering. In environments with large temperature differences between day and night or high humidity, it continuously absorbs moisture from the humid air inside the cabinet, preventing condensation from accumulating on the surface of electrical components. The baffle plate 7 works in conjunction with the water-absorbing resin layer 8 to control the humidity inside the cabinet within a suitable range, preventing corrosion or short circuits of electrical components caused by condensation in salt spray environments, and ensuring the stable operation of the new energy ship's power system in humid and vibrating marine conditions.
