The elastic first connecting rod 61 and the second connecting rod 62 form a staggered network support structure, which can absorb transverse vibration energy through elastic deformation when the ship is rolling, so as to avoid the structure fracture of the dehumidification tower 63 caused by rigid connection.

[0044] Working principle:

[0045] When the ship is running and vibrating, the arc-shaped structure of the elastic rod 32 deforms in the horizontal and vertical directions at the same time. At this time, the spring 33 sleeved on the rod body is guided by the arc of the rod body to produce synchronous bending. Since the two ends of the spring 33 are fixed in the insertion hole of the punching block 31, the deformation amplitude is limited within the bending radius of the elastic rod 32, thereby forming a bidirectional buffering effect.

[0046] The track 21 is flexibly connected with the anti-vibration assembly 1 through the rubber pad 13. When the ship is vibrating, the track 21 can slightly displace with the rubber pad 13. When the moving block 22 slides in the inner side of the track 21, it drives the punching block 31 in the toughness assembly 3 to move transversely. When the rotating wheel 24 rotates to tighten the twisted rope 34, the bending arc of the elastic rod 32 increases, and the compression amount of the spring 33 changes, thereby adjusting the overall rigidity of the toughness assembly 3.

[0047] The moving block 22 is slidably connected with the slide rail in the inner side of the track 21 through the bottom groove 52. When the electric motor in the rotating wheel 24 is started, the twisted rope 34 is wound or released under the action of the rotation of the rotating wheel 24, so as to deform the elastic rod 32. When the moving block 22 moves transversely along the track 21, it drives the punching block 31 to synchronously displace through the rigid connection, so that the X-shaped intersection angle of the two elastic rods 32 changes, thereby adjusting the pre-tightening force of the spring 33.

[0048] The two fixed plates 41 are connected through the bolts 43 to form a frame structure with adjustable spacing. The heat exchange rod 44 and the guide rod 45 form an interlaced support network. The plurality of heat exchange plates 5 are sleeved on the heat exchange rod 44 through the round holes 53 and slide along the guide rod 45. The slide plate 47 is magnetically attracted to the bottom of the support rod 46, so that the support rod 46 can move along the track 21 and remain stable. When the ship is rolling, the support rod 46 can move on the top of the slide plate 47 by magnetic attraction.

[0049] The elastic first connecting rod 61 and the second connecting rod 62 form a staggered net-shaped support structure, which can absorb transverse vibration energy through elastic deformation when the ship is rolling, and avoid the structure fracture of the dehumidification tower 63 caused by rigid connection. The carbon powder plate stacking structure of the dehumidification tower 63 forms a multi-stage adsorption channel through the interlayer gap. When the humid air flows through, the carbon powder layer can capture water molecules, and the bottom exchange plate 64 is provided with a fan which can generate negative pressure airflow after starting, so that the bottom water vapor is quickly discharged to prevent negative effects on the equipment.
