The specific embodiment
As Figure 1-Figure 4, FPSO mooring float of the present invention comprises hull 10 and a float 20 with the structure that is connected, frees of hull, wherein as shown in Figure 3, it comprises a cone portion 21 and a base 22 to the shape of float 20, and the bottom surface of cone portion 21 is fixed on base 22.The base 22 of float is cylindrical, inside establishes sealed module, can realize by water injection ballast, also can the draining inflation realize floating.The cone portion 21 of float consists of a matrix round platform (frustum of a cone), but the top of cone portion 21 is not round section, the part conical surface at matrix round platform top is cut out a plurality of planes 25, make the end face of cone portion 21 be equilateral polygon, form the shape of " old name for the Arabian countries in the Middle East's ground circle " (or " square top and round bottom ").As shown in Figure 4, in the present embodiment, the end face of cone portion 21 is regular hexagon, and this regular hexagon be described matrix round platform tip circle in connect regular hexagon, in Fig. 4, broken circle (inner circle) means the tip circle of matrix round platform, and solid line circle (cylindrical) means the end circle of matrix round platform (namely cone portion 21).
Continuation is with reference to Fig. 1, with the shape of float, adapt, hull 10 is provided with the conical through-hole 11 that can hold float cone portion 21, but the tapering of conical through-hole 11 is slightly less than the tapering of float cone portion 21, thereby between the male cone (strobilus masculinus) of the inner conical surface of conical through-hole 11 and cone portion 21, there is certain gap, can make like this float in uphill process, between float and hull, have enough collision contact surfaces, guarantee that simultaneously hull conical through-hole 11 has enough spaces that float is floated smoothly.The top of conical through-hole 11 arranges polygon clamping device 16, the top of cone portion 21 can be clamped.As shown in Figure 5, polygon clamping device 16 consists of a plurality of clamping slide blocks 161, the quantity of clamping slide block 161 equates with the limit number of cone portion end face equilateral polygon, be in the present embodiment six, described clamping slide block 161 is arranged along Central Symmetry, under the driving of actuating device, can do centripetal or centrifugal slip along slideway 162, thereby produce, clamp or loosening up.In the present embodiment, clamping slide block 161 can be driven by hydraulic efficiency gear.When polygon clamping device 16 clamps the equilateral polygon at cone portion 21 tops, can stop the rotation of float with respect to hull.
When the top of cone portion 21 was clamped by polygon clamping device 16, the latching device in conical through-hole 11 can further be locked float.In the present embodiment, latching device is a plurality of latches that can slide 13 that are uniformly distributed along the circumference, and on the surface of float cone portion 21, is provided with accordingly the pin-and-hole 23 (seeing Fig. 3) that can match with latch 13, and pin-and-hole 23 arranges the position near cone portion 21 bottoms.The quantity of pin-and-hole 23 equals the limit number of cone portion end face equilateral polygon, and in the ordinary course of things, the limit number of cone portion end face equilateral polygon is even number, simple in structure in order to make, and the quantity of latch 13 is set to half of pin-and-hole 23 quantity.As shown in Figure 2, pin-and-hole 23 is six, and latch 13 is three, all is uniformly distributed along the circumference, and pin-and-hole 23 can match with latch 13 at interval of one.The bus at place, pin-and-hole 23De center is just in time aimed at the mid point on every limit of end face equilateral polygon, even polygon clamping device is aimed at the dislocation of cone portion top equilateral polygon, latch 13 still can insert in pin-and-hole 23.
The effect of latching device is when float is connected with hull, by float and hull locking, avoids rotation and up-and-down movement between float and hull.When freeing, latching device can loosen float again.In the present embodiment, latch 13 is driven by hydraulic efficiency gear, can advance and retract, and is appreciated that latch 13 also can be driven by other actuating device.Equally, latching device also can adopt other structure of the prior art, such as adopting three-jaw chuck similar structures of the prior art etc.When adopting different latching devices, the surface of cone portion 21 also can arrange different counter structures, and is not limited to pin-and-hole 23.
As shown in Figure 2, in the present embodiment, hull 10 is circular configuration, and conical through-hole just in time is positioned at hull 10De center.
As shown in Figure 1, the bottom surface of hull 10 and the contacted position of float base 22 are provided with annular anti-collision ring 12.The upper deck of hull 10 is provided with winch 14, and winch 14 is connected with the top of float by hawser 15.And the surface of cone portion 21 is provided with many along generatrix direction and protrudes from surperficial rubber anti-collision bar 24, can play buffer action when float and hull collision.In the embodiment shown in fig. 4, anticollision strip 24 also has six, is spaced with the pin-and-hole 23 on cone portion 21 surfaces.
In order more clearly to understand the present invention, below to connection of the present invention with free process and describe.
As shown in Figure 6, when float 20 is wanted to be connected with hull 10, in the float cabin, ballast water is discharged in inflation, dependence buoyancy rises, hull 10 relies on the temporary mooring fixed position, polygon clamping device 16 is in relaxation state (as shown in Figure 5), and latch 13 also is in retracted state, avoids bumping with float.
As shown in Figure 7, when the float top rises to the main deck position, the clamping slide block skids off along slideway, and polygon clamping device 16 is tightly clamped the float upper end, as shown in Figure 8, realizes Primary Location.In the uphill process of float, can use winch to drive hawser and lift float, avoid float and hull to bump against, and play the effect of auxiliary positioning.
As shown in Figure 9, after Primary Location, owing between float and hull, can not relatively rotating, just can utilize at an easy rate latching device to lock.Latch 13 stretches out under the promotion of hydraulic efficiency gear, just in time inject in the pin-and-hole on cone portion surface, pins float, prevents that float from rocking or rotating.
Be appreciated that if as prior art do not have the polygon clamping device at top to carry out Primary Location, between float and hull, exist in relative rotation in situation, it be very difficult latch 13 injecting in the pin-and-hole on cone portion surfaces.
When meeting inclement weather, when float is wanted to free with hull, opposite with said process.At first, polygon clamping device and latching device are regained, and break away from float, then open the water injection hole of float bottom, and float adds ballast water, rely on gravity to sink down under water, with hull, break away from, then with towboat, hull are dragged to safe marine site.
