Type, Spar types basis.Existing Spar types blower foundation is mostly kingpost truss formula structure, has very strong stability against overturning,
But it is easily influenced since structure is single cylindrical be subject to vortex-induced vibration, while cabin is few, and 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 utility model provide a kind of multicolumn floating Spar type blower foundations, which ensures that original Spar types are put down
The characteristic of platform, while the influence of vortex-induced vibration can be reduced, there is good unsinkability.
Technical solution is used by the utility model solves its technical problem：

Include column, reinforcing plate；The column includes a center stand column and four heel posts, connected between column by reinforcing plate to be formed it is more
Rod structure；One end of the 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 link 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.
Preferably, several closed in space are both provided with each column, closed in space improves unsinkability and adjusts
Buoyancy needed for whole platform.
Preferably, the truss structure is made of some vertical support column, collateral beam and heave plates；Heaving plate level is pacified
On vertical support column, collateral beam is used for the connection of heave plate and support column, support.
Preferably, the truss structure is made of 4 vertical support columns, 24 collateral beams, 2 heave plates, heave plate
There is the hole that 3*3 is arranged, to strengthen the heaving of heave plate damping.
Preferably, the anchoring system includes mooring point and more root systems pool cable；The mooring point is arranged on edge-on
On column, the mooring point be located at whole floating fan platform centre of buoyancy and center of gravity centre position institute in the plane.
Preferably, the ballast tank is divided into some cabins, and the object more than density of sea water is loaded in cabin to carry
Pressure supply carrying force, makes the reduction of overall structure center of gravity.
Preferably, the ballast tank cabin can select ballast quantity, and with center-of-gravity regulating position, make anchoring system is
Pool is put positioned at the institute in the centre of buoyancy of whole floating fan platform and center of gravity centre position in the plane.
Preferably, 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 utility model has an advantageous effect in 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 structure diagram of the utility model.
In figure：1. heel post, 2. mooring points, 3. ballast tanks, 4. truss cant beams, empty heave plate more than 5., 6. truss upright-columns, 7.
Heel post cabin, 8. double-layer clapboards, 9. gin poles, 10. reinforcing plates.
Embodiment
As shown in Figure 1, the utility model discloses a kind of multicolumn floating Spar type blower foundations, including hard cabin, truss knot
