Embodiment 1
[0029] Such as Figure 1 to Figure 5 As shown, this embodiment includes a choke block 1 fixed on the lower part of the transverse wall plate 32 at the right end of the moon pool 3 and a wave dissipation mechanism 2 arranged at the upper outer corner of the choke block 1, and the choke block 1 is a rectangular parallelepiped shell structure, the housing is provided with horizontal ribs 11 and vertical ribs 12 supporting the housing to improve the strength of the choke block 1 . The wave breaking mechanism 2 includes a plurality of detachable baffles 21 and a central axis tube 22, the bottom of the detachable baffles 21 are embedded in the central axis tube 22 at intervals, and the middle part of the central axis tube 22 is fixed on the horizontal plate of the choke block 1 13 and the vertical plate 14, and the two ends of the central axis tube 22 are respectively welded and fixed on the longitudinal wall plates 31 on both sides of the moon pool 3. The bottom of the detachable ...
Embodiment 2
[0032] Such as Figure 6As shown, the structure of the wave elimination mechanism 2 of this embodiment is basically the same as that of Embodiment 1, the difference is that a plurality of circular holes 131 are respectively opened on the upper plate 13 and the vertical plate 14 of the choke block 1, and the circular holes 131 are respectively opened. The sum of the areas of the holes 131 accounts for 30% of the sum of the areas of the upper plate 13 and the vertical plate 14. The purpose of opening the holes is to make the fluid in the choke block 1 form a relatively independent and connected space. The fluid in this space helps to reduce the sloshing of the fluid in the moon pool 3, and at the same time helps to reduce the impact of the fluid on the choke block 1. impact effect.
Embodiment 3
[0034] Such as Figure 7 and Figure 8 As shown, the structure of the choke block 1 of this embodiment is the same as that of the second embodiment, and the wave breaking mechanism 2 is different from the first and second embodiments, which includes a wave breaking plate 201, a support shaft 202, two support shaft cylinders 203 and Two support bases 204, the left side of the wave breaking plate 201 is welded to the middle of the support shaft 202, the two ends of the support shaft 202 are respectively hinged to the support shaft tube 203, and one end of the support shaft tube 203 is respectively welded and fixed to the longitudinal walls on both sides of the moon pool 3 plate 31. The two ends of the wave breaking plate 201 respectively abut against the support seat 204 on the lower side thereof, the support seat 204 is in the shape of Π, and is respectively welded and fixed on the longitudinal wall plates 31 on both sides of the moon pool 3 . The included angle α between the...
