360 and pylon ladder 370.Third platform 320 and the 4th platform 330 are mountable in otic placode described above (ear shown in Fig. 5
Plate 219) on.Third platform 320 can be hollow structure, have elevator hole 390, elevator hole 390 can be used for installing elevator.Elevator
390 surrounding of hole may be provided with guardrail 390a.Elevator can be supported on the first platform 140, and may pass through 240 He of the second platform
Third platform 320, and it is not passed through the 4th platform 330.4th platform 330 may be provided at 320 top of third platform, and can be
Enclosed construction in order to carry out work in every on the 4th platform 330, while the elevator hole on other platforms can be isolated, because
When this works in cabin safety will not be improved there is a situation where falling by elevator hole.Fastening clip for cable plate 350 is settable
On second baffle 220, for being laid out and fixing to cable.
According to an embodiment of the invention, third truss structure 300, which may also include, is arranged in 211 top of the first plane framework
Third truss structure 300 is attached by upper flange 380 with nacelle atop.Specifically, upper flange 380 may be provided at first
On the top boom 211-2 of plane framework 211.
Above when the first truss structure 100, the second truss structure 200 and third truss structure 300 are described, retouch
It has stated and has opened up manhole on the first baffle 215 being laid on the first plane framework 211, is being connected between first baffle 215
Second baffle 220 at the example of fastening clip for cable plate and ladder is set, however, the present invention is not limited thereto can change people as needed
The setting position in hole, fastening clip for cable plate and ladder.
According to another embodiment of the present invention, it is possible to provide a kind of wind power generating set including pylon described above.And
And pylon according to the present invention can be used for conventional straight drive and double-fed unit, can also be applied to novel vertical axis wind power generation
Unit.According to an embodiment of the invention, beneficial effect not limited to the following can be obtained.
1, it is circumferentially connected to each other to form lattice tower by monomer truss, lattice tower can achieve conventional head tower
Structural strength possessed by frame or steel and concrete structure, but the costs such as required steel much smaller than conventional wind-power generating unit tower at
This, effectively reduces the cost of unit per kilowatt, improves the unit market competitiveness.
2, need to prevent vortex-induced vibration, i.e., the knot calculated according to simulation in current high tower wind power generating set hoisting process
Fruit installs disturbing flow device (flow-disturbing block) manually in upper several sections of towers, and which has flow-disturbing effect undesirable, the peace of disturbing flow device
Dress mode is cumbersome, and the dismounting of disturbing flow device has many drawbacks such as certain security risk.Pylon according to the present invention allows wind to wear
Pylon is crossed, while spliced tower cross section is polygonized structure, the wind that all directions can be blown, which is broken up, changes wind
Frequency avoids the generation of vortex-induced vibration, can omit disturbing flow device, improves flow-disturbing effect.Meanwhile conventional towers structure is compared,
During tearing machine open, without crane cooperation in high aerial installation disturbing flow device, operation safety risk is eliminated, the machine of tearing open is significantly reduced
Cost.
3, pylon according to the present invention is lattice tower, therefore wind can be allowed to pass through so wind area is small, peace
It is not susceptible to shake during dress, it is smaller by extraneous air speed influence, therefore the upper limit of lifting wind speed can be improved, increase lifting
Window phase.
4, being gradually increased with unit individual capacity needs by increasing hub height (that is, tower height) and increasing
Length of blade (i.e. increase wind sweeping area) obtains better wind-resources.The pylon structure support lifting that diameter is bigger is needed at this time
Measure the major component of increased blower, thus pylon be easy to appear during transportation superelevation, ultra-wide, it is overweight phenomena such as, to transport
Cost and period bring large effect.Pylon according to the present invention is spliced by monomer truss, therefore improves monomer
The conevying efficiency of truss.Meanwhile compared with the steel pylon of split-type, truss-like truss of the invention has assembled simple, spelling
Fill the advantages that high-efficient.
5, low wind speed area develops the development trend that high tower wind power generating set has become future, and current high tower is main
Using steel and concrete structure (bottom uses head tower structure using concrete, top), used between every section and every section of steel and concrete structure
It sits slurry to be adhesively fixed, entire concrete tower segments carry out tensioning using steel strand wires and fix.If necessary to remove wind-force hair
Motor group, concrete tube section removes difficulty and dismounting is at high cost, it is possible that concrete tower is retained in original seat in the plane
Situation causes destruction to external environment.Compared with the pylon of steel and concrete structure, pylon of the invention is easy to remove.
6, every section and every section are substantially identical in the vertical direction for the second truss structure, therefore according to different height
Pylon need to only increase and decrease the quantity of the second truss structure, therefore the manufacturing method of pylon of the invention is very simple.
Although having show and described some embodiments of the present invention, it will be understood by those skilled in the art that not taking off
It, can be to these embodiments in the case where from the principle and spirit of the invention defined by the claims and their equivalents
It modifies.
