Description

The marine wind electric field fan basis
Technical field
The utility model relates to a kind of marine wind electric field fan basis.
Background technology
China is vast in territory, and seashore line length, offshore wind energy resource are very abundant.Marine wind electric field have wind speed large, effectively generating dutation long, do not take land, apart from advantages such as load center are near, but have good DEVELOPMENT PROSPECT.At present, the offshore wind farm construction is in the ascendant in the world, and domestic offshore wind farm is formally starting also, is badly in need of catching up with and surpass the international high standards.
Sum up the in the world blower foundation of built main marine wind electric field, mainly contain three kinds of structures:
1, single-pile foundation: in sea bed, directly squeeze into a large diameter steel pipe pile as the basis of blower fan (wind-powered electricity generation unit).The overwhelming majority all adopts single-pile foundation in the built marine wind electric field at present.The major advantage of single-pile foundation is that structural shape is simple, easy construction, and major defect is that compliance is not strong.Along with the fast development of wind-powered electricity generation unit manufacturing technology, single-machine capacity constantly increases, and the single pile diameter that needs is increasing, and pile foundation lifts and squeezes into difficulty and also increases thereupon.On the other hand, the single-pile foundation horizontal rigidity is relatively low, is difficult to satisfy blower fan to the requirement of horizontal distortion in the poor place of sea bed geological conditions.Top layer, domestic neritic area mostly is mud or mucky soil, and the application of single-pile foundation is very limited.
2, many pile leaders body panel basis: adopt and the similar structure of offshore oil jacket platform, in sea bed, place first a steel structure platform that is formed by the steel member, then squeeze into steel pipe pile by the spud leg sleeve pipe on the platform.Many pile leaders frame basis is constantly to increase a kind of foundation structure that the higher requirement of soil rigidity is adopted in order to adapt to the wind-powered electricity generation capacity of power unit, its advantage is that horizontal rigidity is large, major defect is that the later stage operation and maintenance cost is high owing to adopting steel work to cause involving great expense.On the other hand, owing to adopting the mode of driving piles behind the jacket of placing first, before piling, jacket is subjected to the wave flow action to be difficult to precision regulating to calm down the position, be difficult to satisfy the strict planeness requirement that top blower fan tall and slender structure lifting proposes the basis, need to adopt additional connector to carry out secondary leveling, increased the complexity of difficulty of construction and structure.
3, High-Rise Pile Cap Foundation: many steel pipe piles are adopted on this basis, and adopt a larger reinforced concrete pile cap, and the changeover portion (pylon) of steel pipe pile and superstructure is connected.This structure level rigidity is large, and crashworthiness is good, and the changeover portion leveling is convenient.But this structure since arrangement of pile foundation in more among a small circle, foundation pile is stressed larger.The cushion cap area is larger simultaneously, need to bear larger Wave Load when the cushion cap elevation is low.
All there is different shortcomings on above-mentioned three kinds of marine wind electric field fan bases, can not adapt to the fast development of wind-powered electricity generation unit manufacturing technology.When the wind-powered electricity generation capacity of power unit constantly increases, above-mentioned blower foundation difficulty of construction is large, complex structure, rigidity not, be greatly limited.
The utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of marine wind electric field fan basis, when constantly increasing for solution prior art apoplexy group of motors single-machine capacity, blower foundation is restricted, large, the baroque problem of difficulty of construction.
Reach for achieving the above object other relevant purposes, the utility model provides a kind of marine wind electric field fan basis, comprises blower fan pylon, is provided with a plurality of marine cushion caps that are fixed in around the blower fan pylon, and cushion cap is fixedly connected with by bracing frame with blower fan pylon.
Preferably, bracing frame comprises a transition conduit of vertically placing and a plurality of contact bars that are connected connecting transition conduit and cushion cap, and the top of transition conduit is fixedly connected with blower fan pylon.Further preferred, the bar that contacts between each cushion cap and the transition conduit is two, is respectively second line of a couplet tie-rod and first line of a couplet tie-rod; One end of second line of a couplet tie-rod is imbedded cushion cap, and the other end is fixedly connected with the side face of transition conduit; One end of first line of a couplet tie-rod is imbedded cushion cap, and the other end is fixedly connected with the side face of transition conduit.Further preferred, the first line of a couplet tie-rod and the second line of a couplet tie-rod that are connected on the same cushion cap are positioned at same perpendicular.
Preferably, a plurality of cushion caps circumferentially evenly distributing along transition conduit.
Preferably, cushion cap is supported on the sea bed by a plurality of foundation piles.
In the such scheme, cushion cap can be comprised of steel concrete, and the material of bracing frame can be steel.
As mentioned above, the utility model marine wind electric field fan basis has following beneficial effect:
1) change single cushion cap into a plurality of cushion caps, increased the spacing of foundation pile, be conducive to reduce the stressed of foundation pile, thereby it is long to reduce stake; Change single cushion cap into a plurality of cushion caps, reduced the gross area of cushion cap, thereby reduce the suffered wave force of cushion cap; Change single cushion cap into a plurality of cushion caps, also reduced basic engineering quantity;
2) engineering quantity under same perimeter of section condition, because the minimizing in stake footpath can reduce corresponding steel pipe pile wall thickness, thereby is saved in the basis that connects by a plurality of small-sized cushion caps;
3) adopt concrete bearing platform, can reduce the requirement to the piling positioning precision, reduced transition conduit the difficulty of leveling is installed, and conveniently adopted taper pile to improve the integral level rigidity on basis.
In sum, this marine wind electric field fan basis has that the rigidity of structure is large, easy construction, engineering quantity are little, the easy advantage such as realization of fan foundation structure leveling, satisfy the continuous requirement that increases blower foundation of wind-powered electricity generation capacity of power unit, adapted to the fast development of wind-powered electricity generation unit manufacturing technology.
