Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment proposes a kind of floating-type offshore wind power foundation, comprise three cylindrical float, wherein larger-size is for installing blower fan main buoy 1, what two sizes were less is time floating drum 2, connected by one-level pipe link 3 between main buoy 1 and secondary floating drum 2, be then provided with to hang down in main buoy 1 and the bottom of time floating drum 2 and swing plate 4.
Main buoy 1 is highly identical with time floating drum 2 but diameter different, the diameter of the present embodiment main buoy 1 is 10 meters, and the diameter of secondary floating drum 2 is 6 meters, forms equilateral triangle between main buoy 1 and secondary floating drum 2 by one-level pipe link 3, certainly, the specification of primary and secondary cylinder can be determined according to the actual requirements.The present embodiment adopts the design of the two kinds of floating drums varied in size, basis is made totally to form dissymmetrical structure, such version makes main buoy after installation blower fan, effectively overcome the asymmetry of structural focus, particularly certain stability can be kept not topple under wind speed or the excessive situation of wave, make structure have good exercise performance simultaneously.Conveniently the later stage adjusts the balance on whole basis, the inside of the present embodiment main buoy 1 and time floating drum 2 then all adopts the process of point cabin structure, namely some cabins are set in main buoy 1 and time floating drum 2, the present embodiment main buoy 1 and each 5 layers of cabin setting up and down in time floating drum 2, every layer of cabin altitude is 5 meters, and every layer evenly arranges again room (not shown) between 3, and each room is fan-shaped, namely the cross-sectional area of each room is fan-shaped, and fan shape center angle is 120 °.The design of the many subdivisions of the present embodiment more neatly according to different operating sea situation, can regulate the ballast of basic design, thus adjusts center of gravity of the present utility model, ensure enough damaged stabilities, play stable effect.
Being connected by one-level pipe link 3 between main buoy 1 and secondary floating drum 2, in order to strengthen steadiness, establishing two-layer one-level pipe link altogether, namely between main buoy 1 and secondary floating drum 2, upper and lower end all realizes connecting between two by one-level pipe link.Equally, in order to strengthen integrally-built steadiness, the present embodiment establishes three grades of pipe links altogether, secondary pipe link 5 for reinforcing then is provided with (namely as in the middle of Fig. 2 between one-level pipe link 3 and main buoy 1 or secondary floating drum 2, secondary pipe link 5 between one-level pipe link and secondary floating drum), be then provided with three grades of pipe links for reinforcing 6 (namely as shown in Figure 3 mark 6) between every two one-level pipe links 3.The cross section of one, two, three pipe link 3 can be circular or square; Secondary pipe link effectively ensure that the reliability and stability between anatomical connectivity; Three grades of pipe links can improve axis and the lateral rigidity of one-level pipe link, guarantee that it is not flexible.Connection mode between each pipe link of the present embodiment and between pipe link with primary and secondary floating drum is for welding.
Hang down swing plate 4 be arranged on main buoy 1 or secondary floating drum 2 bottom, heaving is done relative to 2 of main buoy 1 or secondary floating drum, with reference to figure 4, the shape of swinging plate 4 of hanging down is polygon or circle, in this enforcement, the vertical orthohexagonal design of swinging plate 4 and all adopting under primary and secondary floating drum, the vertical length of side of swinging plate under main buoy is 8m, the vertical length of side of swinging plate under secondary floating drum is 5m, and is all provided with deep floor 7 hanging down to swinging between plate and main buoy or secondary floating drum.With reference to figure 2 and Fig. 3, deep floor 7 is arranged along main buoy or secondary floating drum circumferencial direction, can be triangle or trapezoidal, and the present embodiment deep floor 7 is triangle at right angles, wherein a square edge is fixed on the periphery wall of main buoy or secondary floating drum, and another square edge is fixed on to hang down and swings the upper surface of plate.Leg-of-mutton deep floor structure adds the stability of hanging down and swinging between plate and main buoy or secondary floating drum, and this deep floor also can play the effect subtracting and shake simultaneously, effectively can reduce pitching and the rolling motion of basic design, make whole basis more stable.
To sum up, the utility model proposes a kind of offshore wind power foundation simple and reliable for structure, the symmetry of offshore wind power foundation structural focus is improve by the design of asymmetric floating drum, meet DNV specification the requirement of semi-submersible structure is designed, basic design has very large guarantee in stability, exercise performance is excellent, can support 5MW and above blower fan.
Specific embodiment described herein is only to the utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ 1 herein, main buoy; 2, secondary floating drum; 3, one-level pipe link; 4, hang down swing plate; 5, secondary pipe link; 6, three grades of pipe links; 7, deep floor; 8, the term such as blower fan, but do not get rid of the possibility using other term.Use these terms to be only used to describe and explain essence of the present utility model more easily, the restriction that they are construed to any one additional is all contrary with the utility model spirit.
