Abstract

The invention relates to a wind electricity floating raft structure. A floating raft used for a trilobed windmill group uses a spacial tension structure of a plurality of elliptical cross sections, vertical pipes A and A1, an upper carling B, a lower carling B1, a crossbeam C, etc. to form huge cross sectional moment of inertia, thereby reducing slender proportion. The vertical pipes A and A1 aredistributed without uniform heads. Penetrant space, subulate head and tail of the vertical pipe and stand pipes with elliptical cross section minish wave resistance and concentrated elevating power. A rear hanging floating raft A3, a long arm of force G, a shock absorber, a sensor J, etc. are hung and connected by a gemel F to maintain the balance of overturning moment. A structure that two amalgamated pipes D1 and D2 are used causes the length of the vertical pipes A and A1 to be disassembled, thereby being convenient to produce, repair and transport. The A3 floating raft extended by rear hanging also ensures that the entire large structure becomes easy to control and safe.

Description

Wind eletricity big floating-raft structure

The invention belongs to the oceanic winds electrical domain, is a kind of wind eletricity big floating-raft structure that floats Bamboo-raft greatly about three blade wind power machine groups.

Advanced country reduces wind power cost for improving constantly wind energy efficiency in recent years, rotor diameter greatly to surpassing Φ 120m, and for environmental friendliness, catch more wind energy, march to the ocean.

Want to be planted in the big wind wheel of 100 meters of floating Bamboo-raft and height, want to hold its huge moment of throwing, perhaps tsunami, the violent storm and roaring waves long floating Bamboo-raft longitudinal tubule (L tubule) or the like that can fracture all is a realistic problem, and this programme is want now to be set forth in down at these:

The longitudinal tubule (L tubule) A and the A1 of Fig. 1 oval cross section (major axis is in the plummet direction), upper and lower longeron B and B1; The layout that longitudinal tubule (L tubule) is not flush (tip is not in same aspect); The spatial structure of stretching type strengthens the lifting effect of opposing wave and the antidetonation bending resistance endurance of resisting nature disaster.AS is a water surface curve, and W is a wind direction.

Longeron B goes up crossbearer crossbeam (illustrate three) C, on establish the pylon foundation E1 of wind energy conversion system, get a bird's eye view into the big basis of cross form by several parallel longeron B and several crossbeam C, H and E1 formation; Span ≈ 380m after longitudinal tubule (L tubule) A and the A1 combination, the tilting moment in the time of can not resisting the wind energy conversion system running rests on damping, the sensor J (schematic symbols) with the top end of long-armed G, safeguards the balance tilting moment with the long arm of force.Discharge the power of the long arm of force G of come-up-increase lifting of water in the watertight batten down among the quantitative following longitudinal tubule (L tubule) A3-suitably by pressure transducer J by computer order vertical tube D3 when wind speed is very big.

The numerical value of longitudinal tubule (L tubule) A and A1 combination total span 380m for purposes such as safety, repairing, land transportations, is with two sections combinations.Pairing and manage D1 and D2 under water the section unload bolt by the diver, all the other are fastening as usefulness bolt and longeron B on the T shape head waterborne, easily unload, so, this part is from pairing and manage D1 and begin up to T, the whole parts of tension structure part that A and the A1 longitudinal tubule (L tubule) up to T1 of turning left connects it are pulled down (and the bracing cable between other longitudinal tubule (L tubule) of its left and right sides is less, available quick-release hasp unloads at once); Longeron B above this moment T shape head still in situ, it is put by the H crossbeam and tangles (the H crossbeam rests on the many longeron B of other left and right sides) with the capable bracing cable K of umbrella.

Equally, the A on the right side of vertical tube D2 and A1 and B1 longeron, tension structure also can unload; Wind-force support E1 is very big, rests again on three C crossbeams and the several parallel longeron B, so harmless.

No matter will repair all and can unload appears in the longitudinal tubule (L tubule) A at which position and A1, generally do not hinder wind energy conversion system to run well.The floating Bamboo-raft of wind mill group can lift by crane or overhaul to the water surface with airbag lift voluntarily.

All longitudinal tubule (L tubule)s all by length 12.5m separately separately the more piece pipeline section of sealing be combined into, all be provided with in the vertical tube D of the floating pipeline section of every joint security information automatically mirror look the computer centralized control of leading to waterborne, know the floating pipeline section of which joint have do not leak or the A pipe of the bottom in the setting-out cabin in the control of moisture storage capacity.

Just can use safely when wind eletricity big floating-raft only assembles very big wind mill group, the big wind energy conversion system of separate unit just is not suitable for floating over wind-power electricity generation on the ocean.

Fig. 2 is that to be combined into the left and right sides two-end structure of three-view diagram plan view longitudinal tubule (L tubule) A, the floating pipe of single-stage just the same; It is an oval cross section to left view as can be known; Fig. 3 is seen in amplification in the top view; About two Aa represent the floating pipe of two joints of butt joint mutually, Ab be about the oval rubber sheet gasket of two same goods, back-to-back superimposed, with the porous bolt hole around the annular, bolt location; The wedge shape projection that oval ring is arranged on the plane of Ab is just in time wedged in the groove that the end face of Aa is complementary, when being subjected to bolton power, and can automatic wedging, seal action.The screw head of AC constitutes L shaped elbow, and the inner orifice edge of hooking Aa does not make its rotation, and D is the end face of expression vertical tube.

The Aa material is entitled as " for a automotive casting high-strength material " literary composition, i.e. high impact modified polypropylene of low temperature according to Science and Technology of Shanghai newspaper (2007.9.12); Massive rotationally moulded equipment rotational moulding through repacking slightly forms.

Advantage: 1. not flush longitudinal tubule (L tubule) A and the A1 of the upper and lower layers of oval cross section, add, longeron B and space multistory tension structures such as B1 and crossbeam C down, form very big cross sectional moment of inertia, reduced slenderness ratio; 2. with the big arm of force of long-armed G lift, the huge tilting moment of opposing and balance wind energy conversion system; 3. with relatively short longitudinal tubule (L tubule) A and A1 segmentation combination, and after articulate floating Bamboo-raft A3, with the structure of hinge F (hinge peso good, do not run foul of each other between longitudinal tubule (L tubule) before and after can not causing), make the floating Bamboo-raft can " balance voluntarily " and be easy to using marine site " voluntarily " to repair to change that each joint is floating manages.
