The utility model relates to a hollow pillar of positive back taper has improved wind turbine foundation's anti ice performance greatly. And change the negative pressure drum of cylinder form into the rotary -table structure, providing the use amount that reduces the material under the condition of equal negative pressure, reduce project cost. Be particularly useful for the deep sea, and have the region of higher anti ice requirement.

Description

A kind of floating anti-ice tension leg blower foundation
Technical field
This utility model relates to a kind of floating anti-ice tension leg blower foundation, is particularly well-suited to ice formation, deep-sea.
Background technology
Tradition floating tension leg blower foundation generally comprises for carrying the upper brace of tower and fan blade, cylinder type hollow column, cylindrical negative pressure cylinder, tension force anchor cable.
In this structure, its pressure is perpendicular to column outer wall, anti-ice poor performance by static state that cylindrical column is subject to or dynamically floating ice, and blower foundation is operationally unstable, greatly limit the probability of its at sea floating ice area applications.
Being additionally, since tension leg blower foundation relies on the hydraulic pressure that negative pressure cylinder is formed to realize stablizing of blower foundation, and hydraulic pressure depends on the degree of depth and the hydraulic pressure effective active area in marine site, negative pressure cylinder place. Cylindrical negative pressure cylinder is not optimized structure, manufactures cylindrical negative pressure cylinder and often results in the waste of material, and construction costs is high.
Technical term is explained as follows:
Positive inverted cone: the technical term of this area, by docking the wide structure narrow, middle of two ends up and down formed bottom two Rotary-tables.
Utility model content
For the problems referred to above, it is effective that this utility model aims to provide a kind of anti-ice, is applied to the more economical applicable floating tension leg blower foundation in ice formation, deep-sea.
This utility model solves the technical scheme of problem: a kind of floating anti-ice tension leg blower foundation, including the upper brace for carrying tower and fan blade, it is fixed at least three hollow columns bottom upper brace, at least three negative pressure cylinder in press-in mud face, seabed, the tension force anchor cable that hollow column and negative pressure cylinder connected, described negative pressure cylinder has and takes out/water injection hole, described hollow column is positive inverted cone, and the elevation of hollow column is always positioned on sea level.
In such scheme, traditional cylinder type hollow column is set to positive inverted conical shape, and owing to hollow column changes along with water level rises and falls, the elevation of floating ice position depends on sea level elevation, now the column of positive inverted conical shape fluctuates up and down with water level, forms floating type ice resistant structure. When static or dynamic floating ice aligns inverted cone column applying pressure, its planform itself can by vertical pressure initiation component, it is achieved anti-ice effect.
In order to ensure stability during blower fan normal operation, many hollow column cloth postpone, and the centre of buoyancy of its structure is positioned on tower axis.
Further, it is connected by support bar between described hollow column, carries out structural strengthening, to ensure the stability of substructure.
Further, described hollow column is bundled with controlling the balancing weight of column ballast. Make column elevation be always positioned on sea level by controlling the ballast of column, anti-ice effect can be realized by the column of positive inverted cone when sea freezes.
Further, described negative pressure cylinder is hollow Rotary-table structure. Negative pressure cylinder relies on deadweight to sink to seabed, after sinking to mud face certain depth, by water pump and air pump by the formation negative pressure that is evacuated in cylinder, negative pressure cylinder is securely seated between sea bed. When needing to remove or shift, it is possible to from taking out/water injection hole water filling, form malleation and then negative pressure cylinder is extracted, achieving the recycling of resource with only small cost.
Preferably, described hollow column is provided with three, arranges in equilateral triangle.
Preferably, described negative pressure cylinder is provided with three, arranges in equilateral triangle.
Of the present utility model it has the advantages that:
1. design the hollow column of positive inverted cone, substantially increase the anti-ice performance of blower foundation.
2., owing to tension leg blower foundation relies on the hydraulic pressure that negative pressure cylinder is formed to realize stablizing of blower foundation, hydraulic pressure depends on the degree of depth and the hydraulic pressure effective active area in marine site, negative pressure cylinder place. The negative pressure cylinder of cylinder form is changed into the Rotary-table structure that upper end is little, lower end is big, reduces the consumption that makes of material when providing equal negative pressure, reduce construction costs. And can be easily achieved blower fan displacement or remove.
3. this blower foundation is particularly suited for deep-sea, and has the region that higher anti-ice requires. Floating blower foundation avoids at deep-sea pile sinking, makes blower foundation safety and economy all be improved.

Detailed description of the invention
As shown in Figures 1 to 3, a kind of floating anti-ice tension leg blower foundation, including the upper brace 3 for carrying tower 2 and fan blade 1, is fixed on three hollow columns 4 bottom upper brace 3, three negative pressure cylinders 7 in press-in mud face, seabed, the tension force anchor cable 6 that hollow column 4 and negative pressure cylinder 7 connected.
Described negative pressure cylinder 7 is hollow Rotary-table structure. Negative pressure cylinder 7 has and takes out/water injection hole.
Described hollow column 4 is positive inverted cone, and upper and lower two ends width narrow, middle, the elevation of hollow column 4 is always positioned on sea level.
Described hollow column 4 and negative pressure cylinder 7 are all arranged in equilateral triangle.
It is connected by support bar 5 between hollow column 4. Hollow column 4 cloth postpones, and the centre of buoyancy of its structure is positioned on tower 2 axis.
Described hollow column 4 is bundled with controlling the balancing weight of column ballast.
