Description
Technical field
It is specifically marine to conventional tension leg formula the present invention relates to a kind of new marine windmill Bracing Systems
Improvement is optimized in wind energy conversion system Bracing Systems, absorbs Spar formulas floating drum and combines shape with the advantages of catenary tension force key
Into a kind of structural system, this novel support structure system can preferably ensure wind energy conversion system safety military service.
Background technology
For land wind-powered electricity generation, offshore wind farm has following unique advantage, and e.g., wind field is wide, wind-force is stable, wind-powered electricity generation
Capacity of power unit is big, by criteria for noise limited it is small, can economize the land resource, beneficial to realizing scale etc..Tension leg type is marine
Wind energy conversion system (Tension Leg Platform Wind Turbine, TLPWT) is developed by tension leg platform (TLP), in being suitable for
Etc. the marine site of the depth of water, it is fixed using vertical type tension force key mooring, and 3 to 4 spar structures are installed in the tower bottom of wind energy conversion system,
Floating drum cross sectional shape is mostly circular or square, and floating drum can provide buoyancy for overall structure.The tension force key both ends end with floating drum respectively
Portion is connected with seabed, and during normal service, tension force key is in tensioning state.Because simple in structure, tension leg type Oversea wind equipment
There are wide application and promotion prospect.But tension leg type marine windmill is when running into severe sea condition, it may occur that lateral to move
It is dynamic, and then cause tension force key to produce sufficiently large internal force and wind energy conversion system could effectively be constrained, tension force key internal force
Increase increases the risk of its failure, and tension force key can trigger the rollover of whole wind energy conversion system after failing in succession.Marine windmill is often
Distribution in flakes, forms marine wind field, if the wind energy conversion system to collapse collides during drifting about with other wind energy conversion systems,
The destruction of other wind energy conversion systems will continuously be caused.On the whole, existing marine windmill Bracing Systems exist as follows substantially
Some deficiency：
1), change of vertical its internal force of tension force key to external loads is more sensitive, especially for the change of lateral load
Change, structure tension force key internal force under the action of severe sea condition easily raises and then in the presence of the risk of failure, the failure of tension force key must
It will cause the rollover of wind energy conversion system entirety, therefore, the safety of tension force key can directly affect the service life of whole wind energy conversion system.
2), the overall stability of wind machine structure is poor.The supporting structure of wind energy conversion system ties up to larger wind, wave, stream loading
Under effect, the tension force key of tensioning state is once fail, and total system turns on one's side run-off the straight, and the wind energy conversion system on top will fall
Water fails.And often large stretch of arrangement forms wind field to marine windmill, single tension force key it is disrumpent feelings will cause the rollover of structure into
And causing the successive disrumpent feelings of other tension force keys, structure will drift about in the lower of unconfined situation, endanger wind field other wind
The safety of power machine.
For above-mentioned deficiency, the present invention proposes wind energy conversion system Bracing Systems on a kind of stretched wire line style combined type sea,
Power key (4) uses catenary form, can provide the characteristics of horizontal direction is with vertical direction component using catenary, be opened to reduce
Internal force of the power key (4) in the case where wind energy conversion system bears horizontal loads, so as to reduce the failure probability of tension force key (4), Jin Eryan
The service life of tension force key is grown.Meanwhile install the height of C.G. that Spar (5) are used for adjustment structure additional below tower (2), carry
The stability of high structure, while facilitate the righting in structure installation process and the installation of tension force key.
The content of the invention
The object of the present invention is to provide wind energy conversion system Bracing Systems on a kind of stretched wire line style combined type sea, using catenary

The adjustment of ballast size, reaches reduction structural focus, improves the purpose of structure stability.Ballast can be carried in structures slope, rollover
For righting moment, the stability of structure can be effectively improved.
Wind energy conversion system Bracing Systems on a kind of above-mentioned stretched wire line style combined type sea, wherein, floating drum (3) is with radial, phase
The mutual equal mode of angle is arranged symmetrically in the periphery of tower (2), and the cross sectional shape of floating drum (3) is circular, rectangle or polygon,
Part buoyancy can be provided for structure, and be also the main source of structure reserve buoyancy.
Wind energy conversion system Bracing Systems on a kind of above-mentioned stretched wire line style combined type sea, in wind energy conversion system during one's term of military service, catenary
Formula tension force key (4) is in tensioning state, constrains moving freely and rotating for wind machine structure, has ensured that marine windmill can be with
The trouble free service in certain scope of activities.
Above-mentioned novel combination type marine windmill Bracing Systems, wherein being carried out using catenary tension force key (4)
Mooring, since the tension force of catenary tension force key (4) can provide horizontal and vertical both direction component, works as wind machine structure
When being subject to larger external force effect to be moved, limiting the mobile part catenary tension force key (4) occurred will further open
Tightly, while it produces the efficiency of horizontal component and will improve, the further increase of limiting structure displacement, and towards moving direction
The tension force of part catenary tension force key (4) is since relaxation can decline, and until horizontal component is zero, this will also relax internal force and has increased
The further increase of big part catenary tension force key (4) internal force；Due to the cooperation of both direction tension force key (4), and
The raising of horizontal component efficiency is provided during power key (4) tensioning, tension force key is can effectively avoid and is moved in wind energy conversion system occurred level
During tension force the occurrence of uprushing, and then the probability of tension force key failure can be reduced, so as to improve equipment safety military service
