Technical field
The utility model relates to a kind of floating offshore wind farm platform.Be applicable to the civil engineering of Oversea wind power generation industry.
Background technology
Common offshore wind farm basic design pattern comprises single pile basis, many pile foundations, gravity type foundation etc.
Along with the development in offshore wind farm field, step into to the deep-sea and to present trend.Build wind energy turbine set in the depth of water greater than the greater coasting area of 50 m, the cost on fixed type pile foundation or jacket-type basis will be very high, and the buoyant foundation structure is comparatively desirable selection.This basis is anchored to sea bed as the platform that wind machine is installed with anchoring system, and its cost is relatively low, and convenient transportation.Must there be the weight of buoyant support wind-powered electricity generation unit the buoyant foundation, and in acceptable limit, can suppress to tilt, rock with normal direction and move.
Summary of the invention
The technical matters that the utility model will solve is: to the problem of above-mentioned existence, provide that a kind of construction and installation are quick, cost is low, stressed good floating offshore wind farm platform.
The technical scheme that the utility model adopted is: a kind of floating offshore wind farm platform; Have some the wind-powered electricity generation unit topsides that constitute by tower tube, cabin, wheel hub and blade and be fixed in the anchoring system on the sea bed; It is characterized in that: the root of each tower tube all is connected with the buoyancy tank platform through linkage section, and the buoyancy tank platform is fixed through wirerope and anchoring system.
Said buoyancy tank flat-bed is shaped as how much polygons that are spliced by a plurality of steel box floating drums, connects into integral body through the strut perforation between each linkage section and between linkage section and the floating drum.
The junction of said strut and floating drum is provided with brace panel.
Between said linkage section and the tower tube for grouting is connected, welding and bolt.
Said anchoring system is other fixing pattern of negative pressure barrel base, gravity type foundation.
The beneficial effect of the utility model is: many typhoons group of motors can be installed simultaneously, adopt the buoyant foundation structure to be applicable to the deep-sea zone of the depth of water greater than 50m; Stability Analysis of Structures is stressed good; Land fabrication, the floating type transportation reduces the marine operation amount, convenient transportation, cost is relatively low.

Fig. 2 is the block diagram of the utility model embodiment 2.
Fig. 3 is a buoyancy tank flat-bed birds-eye view in the utility model.
The specific embodiment
Embodiment 1: like Fig. 1, shown in Figure 3, embodiment 1 is a kind of floating offshore wind farm platform that 3 typhoon group of motors can be installed simultaneously.It is made up of topside (comprise tower tube 7, blade 10, cabin 8, wheel hub 9 and flange, berthing member etc., be as good as with conventional offshore wind farm), buoyancy tank platform 2, strut 3, wirerope 4 and anchoring system 5.
Said buoyancy tank platform 2 is the similar equilateral triangle structure that a plurality of steel box floating drums constitute, and the physical dimension of buoyancy tank platform 2 constitutes in the present embodiment: being connected to radius in buoyancy tank platform 2 inner spaces does rThe circle of=62m, outer most edge is external in radius RThe circle of=87m, outboard float length L=53m, middle floating drum length l=36m, corner's floating drum width W=20m, angle θ=37 ° (seeing Fig. 2).The root of each tower tube 7 all is connected (can adopt grouting connection, welding and bolt) through a linkage section 1 with buoyancy tank platform 2, give buoyancy tank platform 2 with the Load Transfer that topside is born.Connect through alternating expression steel strut 3 between linkage section and the linkage section and between linkage section and the floating drum and be connected, stable with agents enhance overall; Strut 3 is strengthened with the floating drum junction, adopts brace panel 6 measures such as grade that are provided with.This example is connected fixing through wirerope 4 with anchoring system 5 on being fixed in seabed 11 in three ends of buoyancy tank platform 2.
Said wirerope 4 is many wireropes or cable wire, and wirerope 4 links to each other buoyancy tank platform 2 with anchoring system 5 on being anchored at sea bed, keeps the position of platform, regulates its stability.To choose the wirerope and the number of appropriate size according to connecting buoyancy tank platform 2 and anchoring system 5 required tension force during enforcement.
Said anchoring system 5 designs according to sea bed soil property situation, marine environment condition and the required anchor force of structural entity, and its pattern can be fixedly pattern of negative pressure barrel base, gravity type foundation or other; The laying mode is inside and outside two-layer each 3.
Embodiment 2: as shown in Figure 2, present embodiment is similar basically with embodiment 1 structure, and difference only is: a wind-powered electricity generation unit of this example seat in the plane is set to helicopter platform 12 or control cabin.
Buoyancy tank platform 2 can be designed to the different geometric polygon according to requirement of engineering in the utility model, like equilateral triangle, square etc.
Concrete construction method is following:
1, buoyancy tank platform 2 is that land processing factory is prefabricated, with topside (tower tube 7, cabin 8, wheel hub 9, blade 10 etc.) through linkage section 1 be connected accomplish after transportation by driving to specifying the seat in the plane;
When 2, the anchoring system on the sea bed 11 5 adopted the negative pressure barrel bases, the transportation of negative pressure bucket, heavy operation and conventional negative pressure bucket such as pass through were constructed and are as good as;
3, the whole transportation by driving of buoyancy tank platform 2 and topside is fixed through wirerope 4 and anchoring system 5, and is regulated, to meet the required stability requirement that meets of fan operation after being appointed as.
