State can the wind energy gross reserves of development and utilization be about 1,000,000,000 kilowatts, wherein coastal waters can the wind energy content of development and utilization have 7.5
Hundred million kilowatts, be more than the three times of land wind energy resources more than 30 meters wind energy resources more horn of plenties of the depth of water.Below Coast of Europe 20m
Depth of water region wind field fundamental plan is completed, and 20-50m depth of waters region is planned, 50m plans still not actuated with headwater depth.China
Wind energy on the sea is built still than European slow major step.
At present, the basis of offshore wind turbine generator foundation structure can be divided into gravity type, single pile structure, tripod structure, conduit
Frame structure and floating structure.Floating fan foundation structure is applied to abyssal environment (depth of water ＞ 50m), mainly including semisubmersible-type, TLP
Type, Spar types basis.Existing Spar types blower foundation is generally kingpost truss formula structure, with very strong stability against overturning,
But it is single cylindrical due to structure, is easily influenceed by vortex-induced vibration, while cabin is few, unsinkability is relatively low, buoyancy adjustment
Can be poor.
The content of the invention
It is vulnerable to vortex-induced vibration influence, unsinkability and buoyancy adjustment performance to solve existing Spar types floating fan platform
The deficiency of difference, the present invention provides a kind of multicolumn floating Spar type blower foundations, and the foundational skills ensure original Spar types platform
Characteristic, while the influence of vortex-induced vibration can be reduced, with good unsinkability.
The technical solution adopted for the present invention to solve the technical problems is：
Multicolumn spar type floating fan platform includes hard cabin, truss structure, ballast tank and anchoring system, described hard cabin bag
Include column, reinforcing plate；The column includes connecting to form many by reinforcing plate between a center stand column and four heel posts, column
Rod structure；One end of described truss structure is connected with hard cabin, and the other end is connected with ballast tank；Heaving is evenly equipped with truss structure
Plate, anchoring system one end links hard cabin, and the other end is fixed on seabed, and the centre of buoyancy of the multicolumn spar types floating fan platform is higher than
Center of gravity.
It is preferred that, several closed in space are provided with described each column, closed in space improves unsinkability and adjusted
Buoyancy needed for whole platform.
It is preferred that, described truss structure is made up of some vertical support columns, collateral beam and heave plate；Heaving plate level is pacified
On vertical support column, collateral beam is used for connection, the support of heave plate and support column.
It is preferred that, described truss structure is made up of 4 vertical support columns, 24 collateral beams, 2 heave plates, heave plate
There is the hole that 3*3 is arranged, damped with the heaving for strengthening heave plate.
It is preferred that, described anchoring system includes mooring point and many root systems pool cable；Described mooring point is arranged on edge-on
On post, described mooring point be located at whole floating fan platform centre of buoyancy and center of gravity centre position institute in the plane.
It is preferred that, described ballast tank is divided into some cabins, and the object more than density of sea water is loaded in cabin to carry
Voltage supply carrying force, makes the reduction of overall structure center of gravity.
It is preferred that, described ballast tank cabin can select ballast quantity, with center-of-gravity regulating position, and make anchoring system is
Pool point positioned at whole floating fan platform centre of buoyancy and center of gravity centre position institute in the plane.
It is preferred that, the double-layer clapboard for being provided with and being vertically arranged in the closed in space at Water Plane is in the column, with
Improve column strength.
Compared with prior art, the invention has the advantages that：
1. hard cabin replaces an overall single column with five columns, the influence of vortex-induced vibration is reduced.
2. several cabins are respectively divided in each column, damaged stability and unsinkability are improved.
3. ballast tank divides cabin, the ballast of different weight can be provided.
4. the hole that 3*3 is arranged in heave plate, further enhances the heaving damping that heave plate is brought.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1. heel post, 2. mooring points, 3. ballast tanks, 4. truss cant beams, empty heave plate, 6. truss upright-columns, 7. more than 5.
