Description
Technical field
The invention belongs to Offshore Wind Power Generation Technology field, in particular to a kind of tension leg type offshore wind power system.
Background technique
With the increase of the sea area depth of water, the cost on the fixed basis such as pile formula basis, gravity type is higher and higher, especially
After the depth of water is more than 60 meters.Float structure is anchored to sea bed using anchor system by floatation type basis, and as installation wind-powered electricity generation
The basic platform of unit.Especially suitable for deep-sea sea area, have many advantages, such as that cost is relatively low, convenient transportation.
Currently, floatation type offshore wind power foundation structure type has column, semi-submersible type and tension leg type.These platforms exist
Some defects, if column basis waterline is small in face of the contribution of stability, sideway and surging value are larger.Semi-submersible type platform structure letter
It is single, but stability is usually not easy to reach requirement, especially to treat in the design phase, or meet platform using active ballast
Stability requirement.The buoyancy tank of relatively conventional tension leg type offshore wind farm and drag-line often only have 3 to 4 groups on the market, when running
Wherein there is one group in the process to be damaged, ability of losing the job, biggish security risk may be generated to whole system.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of with good stability and safeties
It can, can be improved the tension leg type offshore wind power system of effective generating dutation.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
Tension leg type offshore wind power system, including round-shaped float, bottom plate, Wind turbines and anchor system；Described
Round-shaped float is surrounded and is set on the bottom plate by several fan-shaped floating bodies；A cavity is formed inside round-shaped float；The tower of Wind turbines
Cylinder is inserted vertically into and is fixed in cavity；Anchor system is made of drag-line and anchor block, and drag-line is set to bottom plate lower part, and stay wire end connects
Connect anchor block.
As preferred: bottom plate is matched discoid with round-shaped float.
As preferred: drag-line is uniformly distributed in the circle of bottom plate lower periphery one.
As preferred: round-shaped float is surrounded by 12 fan-shaped floating bodies.
As preferred: anchor block uses reinforced concrete member.
As preferred: anchor system is made of 6 groups of drag-lines and anchor block.
As preferred: seabed is evenly arranged anchor block, and round-shaped float is pulled to b.s.l. by drag-line.
The beneficial effects of the present invention are: with good stability and security performance, can be improved effective generating dutation.
Detailed description of the invention
Fig. 1 is a kind of tension leg type offshore wind farm system structure diagram
Description of symbols: round-shaped float 1, bottom plate 2, Wind turbines 3, cavity 4, drag-line 5, anchor block 6.
Specific embodiment
The present invention is described further below with reference to embodiment.The explanation of following embodiments is merely used to help understand this
Invention.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, also
Can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection scope of the claims in the present invention
It is interior.
Tension leg type offshore wind power system, including round-shaped float 1, bottom plate 2, Wind turbines 3 and anchor system；It is described
Round-shaped float 1 surrounded by 12 fan-shaped floating bodies and be set on bottom plate 2；A cavity 4 is formed inside round-shaped float 1；Wind turbines 3
Tower be inserted vertically into and be fixed in cavity 4；Anchor system is made of 6 groups of drag-lines 5 and anchor block 6, and drag-line 5 is set under bottom plate 2
Portion, 5 end of drag-line connect anchor block 6.Bottom plate 2 is matched discoid with round-shaped float 1.Drag-line 5 is uniformly distributed in 2 lower part of bottom plate
It makes a circle outside.Anchor block 6 uses reinforced concrete member.Seabed is evenly arranged anchor block 6, and is pulled to round-shaped float 1 by drag-line 5
B.s.l..
By adjusting 5 length of drag-line, sea level guarantees that round-shaped float 1 is completely submerged in the sea at record low.Nothing
How to be gone up and down by when sea level, floating body will not float up and down, to guarantee that Wind turbines 3 can work normally.
Round-shaped float 1 is divided into 12 fan-shaped floating bodies, to guarantee the overall stiffness of floating body.When single fan-shaped floating body is due to outer
Rupture loss of buoyance occurs for power, remaining fan-shaped floating body remains to work normally, to guarantee that Wind turbines 3 are safely operated.
6 groups of drag-lines 5 and anchor block 6 are set, after single group drag-line 5 and the failure of anchor block 6, anchor system remains to work normally, from
And guarantees Wind turbines 3 and be safely operated.
