Detailed description of the invention
Hereinafter, with reference to the accompanying drawings embodiment involved in the present invention is described in detail.It addition, the present invention is not limited by this embodiment.Further, the constitutive requirements of following embodiment comprise those skilled in the art and may replace and simple important document, or substantially the same important document.
Fig. 1 indicates that the top view of the schematic configuration of the buoyancy aid involved by present embodiment.Fig. 2 indicates that the sectional view of the schematic configuration of the buoyancy aid involved by present embodiment.Buoyancy aid is the various works floating on the water such as the pedestal of floating landing stage, floating warehouse, floating parking lot, operation ship, oil production platforms, marine windmill.
As shown in Figures 1 and 2, buoyancy aid 10 has buoyancy aid main body 12 and shake minimizing device 14.Buoyancy aid main body 12 is works floating on water surface W.Buoyancy aid main body 12 such as outside is formed by steel plate, is internally formed Packed space.Buoyancy aid main body 12 is by being set to fill the state of air in internal space, and proportion is lighter than water, thus swimming in water surface W.Further, buoyancy aid main body 12 can also be formed total thing by the object that proportion is lighter than water.The buoyancy aid main body 12 of present embodiment is the cuboid that bottom surface (face on the downside of vertical direction) is rectangular.
Shake reduces device 14 and is arranged at the outer rim of buoyancy aid main body 12.Shake reduces device 14 and possesses 4 minimizing unit 20.4 are reduced 4 limits that unit 20 is respectively arranged at the bottom surface of buoyancy aid main body 12.
Reduce unit 20 and there is the connecting portion 24 of plate portion 22 and web portion 22 and buoyancy aid main body 12.Plate portion 22 is the parts that the bearing of trend on the limit of the bottom surface of corresponding buoyancy aid main body 12 becomes the tabular of long side direction, and configuration on the direction that the face (surface) that area is maximum is parallel with the bottom surface of buoyancy aid main body 12.Plate portion 22 is configured to cover the substantially whole region on the limit of the bottom surface of buoyancy aid main body 12.That is, the length of the long side direction in plate portion 22 is roughly the same with the limit of the bottom surface of buoyancy aid main body 12, is configured at position overlapping on the bearing of trend on limit.Further, as in figure 2 it is shown, plate portion 22 is configured at the downside from the bottom surface of buoyancy aid main body 12 away from predetermined distance in vertical direction.Further, as shown in Figures 1 and 2, from vertical direction (direction orthogonal with water surface W) observe time, plate portion 22 is that a part is overlapping with buoyancy aid main body 12, a part of the state overlapping with buoyancy aid main body 12.That is, plate portion 22 is configured near the bottom surface of buoyancy aid main body 12, and a part highlights from buoyancy aid main body 12.
Connecting portion 24 is bar-shaped parts, and plate portion 22 is fixed on buoyancy aid main body 12.The bearing of trend on the limit of the bottom surface of buoyancy aid main body 12 is provided with multiple connecting portion 24, in multiple positions, buoyancy aid main body 12 is fixed in plate portion 22.Further, there is gap between connecting portion 24 and connecting portion 24.
It is structure as above that shake reduces device 14, and plate portion 22 is fixed with the state that there is gap between buoyancy aid main body 12 by connecting portion 24.Further, as above-mentioned from vertical direction observe time, the part in plate portion 22 is overlapping with buoyancy aid main body 12.
Then, Fig. 3 and Fig. 4 function that shake is reduced device 14 is utilized to illustrate.Fig. 3 and Fig. 4 is an illustration for the explanation figure of the action of the shake minimizing device of buoyancy aid.It addition, in Fig. 3 and Fig. 4,1 in multiple minimizing unit 20 is reduced unit 20 and illustrates, but other reduce unit 20 and also possess identical function.
As it is shown on figure 3, in buoyancy aid 10, when the wave in the direction of pushing buoyancy aid main body 12 and plug-flow 50 collide with buoyancy aid main body 12, ripple forces moment 52 to act on buoyancy aid main body 12.Now, shake reduces in device 14, and a part for the current 54 moved because of plug-flow 50 becomes the current 56 between the bottom surface by plate portion 22 and buoyancy aid main body 12.These current 56 become the high velocity stream pushed by plug-flow 50, and therefore the bottom surface near the plate portion 22 of buoyancy aid main body 12 produces the less region of other parts of pressure ratio bottom surface.Thus, the vicinity generation counteracting ripple reducing unit 20 of the shake minimizing device 14 one side in plug-flow 50 side forces power and the counteracting force 58 in the direction of moment 52.Shake reduces device 14 by producing counteracting force 58, can reduce the power produced in buoyancy aid main body 12 when plug-flow 50 acts on buoyancy aid main body 12.
As shown in Figure 4, in buoyancy aid 10, when the wave in the direction of pulling buoyancy aid main body 12 and backwash 60 act on buoyancy aid main body 12, ripple forces moment 62 (forcing the rightabout power of moment 52 with ripple) to act on buoyancy aid main body 12.Now, shake reduces in device 14, and a part for the current moved because of backwash 60 becomes the current 64 between the bottom surface by plate portion 22 and buoyancy aid main body 14, and remaining current become the current 66 of the bottom surface in Returning plate portion 22.That is, when from buoyancy aid main body 12 towards the current of side, plate portion 22, becoming narrow space between the region that plate portion 22 is overlapping with the bottom surface of buoyancy aid main body 12, current are difficult to, by (shipwreck is with flowing), therefore form current 64 and current 66.Thus, increasing from buoyancy aid main body 12 towards the current of side, plate portion 22 resistance near shake minimizing device 14 because of backwash 60, the bottom surface near the plate portion 22 of buoyancy aid main body 12 produces the region that other parts of pressure ratio bottom surface increase.Thus, the vicinity generation counteracting ripple reducing unit 20 of the shake minimizing device 14 one side in backwash 60 side forces power and the counteracting force 68 in the direction of moment 62.Shake reduces device 14 by producing counteracting force 68, can reduce the power produced in buoyancy aid main body 12 when backwash 60 acts on buoyancy aid main body 12.
Gap is there is in buoyancy aid 10 between the bottom surface of buoyancy aid main body 12, and arrange from vertical direction observe time a part of stacked plate portion 22, direction from there through the current between bottom surface and the plate portion 22 of inflow buoyancy aid main body 12, it is possible to form the irreversible stream that the state of current is different.Thus, when plug-flow 50 acts on and when backwash 60 acts on, it is possible to produce the moment of different directions in buoyancy aid main body 12, it is possible to suitably reduced the ripple played a role by plug-flow 50, backwash 60 by counteracting force 58,68 and force moment 52,62.Further, buoyancy aid 10 can pass through to shake minimizing device 14 and efficiently reduce shake, it is possible to reduce the device being installed on buoyancy aid main body 12.
Further, shake reduces device 14 by plate portion 22 is fixed on the simple structure of connecting portion 24, it is possible to reduce the shake of buoyancy aid main body 12.Thereby, it is possible to efficiently reduce the shake of buoyancy aid main body 12 with simple structure.
Shake reduces in device 14, by the region overlapping with buoyancy aid main body 12 in plate portion 22 is set to suitable ratio, it is possible to produce current 56 when making generation plug-flow 50 and current 64,66 appropriate balance when producing backwash 60.Especially, when producing backwash 60, it is possible to be set to the state that current are difficult between the bottom surface by plate portion 22 and buoyancy aid main body 12, it is possible to suitably produce counteracting force 68.
Shake reduces in device 14, by the distance between plate portion 22 and buoyancy aid main body 12 is set to suitable scope, it is possible to produce current 56 when making generation plug-flow 50 and current 64,66 appropriate balance when producing backwash 60.Specifically, when producing plug-flow 50, it is possible to the current 56 compressed are set to the current of suitable speed, when producing backwash 60, it is possible to be set to the state that current are difficult between the bottom surface by plate portion 22 and buoyancy aid main body 12.That is, can be formed between the bottom surface of buoyancy aid main body 12 and plate portion 22 from the current in the direction inside the lateral of buoyancy aid main body 12 than the current in the direction of the Inside To Outside from buoyancy aid main body more easily by stream (water capacity runny stream).Specifically, between bottom surface and the plate portion 22 of buoyancy aid main body 12, from the bottom surface of the buoyancy aid main body 12 in the direction inside the lateral of buoyancy aid main body 12, the current of (near bottom surface) are faster than the current of (near bottom surface) on the bottom surface of the buoyancy aid main body 12 in the direction of the Inside To Outside from buoyancy aid main body.Thus, suitably produce counteracting force 58,68, and the shake of buoyancy aid main body 12 can be reduced more reliably.
At this, buoyancy aid 10 and shake reduce device 14 and are not limited to above-mentioned embodiment.Hereinafter, Fig. 5 to Figure 10 variation i.e. another embodiment that buoyancy aid 10 and shake are reduced device 14 is utilized to illustrate.It addition, in following variation, reduce the symbol that the identical structure mark of device 14 is identical detailed to buoyancy aid 10 and shake.
