Suppress method for oscillating for the second class, the method and structure that many control vortex sheddings in the prior art be present, its
In with spiral strake carry out flow-disturbing structure it is the most commonly used.
The shape height in hand of spiral strake, pitch, screw head number are stated.Different spiral strake shape, to whirlpool exciting
Dynamic inhibition is different.Researcher has carried out big measurement with regard to spiral strake shape to the influence for suppressing efficiency
Examination and research.
Spiral strake can effectively suppress the regular of whirlpool and come off, thus while can effectively suppress vortex-induced vibration,
But this structure type Shortcomings：It is poor universality first, the pre-installation spiral strake of different model pylon vibrationproof tower segments
Length be different, the spiral strake that every kind of model tower uses is different；Secondly manufacturability is poor, due to needing in vibrationproof
The spiral strake of winding installation in advance, Field Force's workload are big in tower segments；It is finally inconvenient transport, due to the length of tower segments
Degree is longer, and the length for the spiral strake for causing to coordinate it to use is longer (being likely to be breached more than ten meters even tens meters), therefore is transporting
It is very not readily transportable when defeated.

The tower vortex-induced vibration protector is sequentially connected by multiple tower vortex-induced vibration protection modules 10 and formed, and is avoided tower whirlpool and is swashed
Vibration protection device length is long, it is oversized caused by it is not readily transportable, in-site installation is inconvenient the problems such as.
In the present embodiment, tower vortex-induced vibration protector is 3, and the circumference of the protection tower segments 20 along place is equal
Even interval setting, multiple tower vortex-induced vibration protection modules 10 of each tower vortex-induced vibration protector are sequentially connected and helical disk
In protection tower segments 20 where being wound on.
, can be by using different numbers using modular thought to realize the generalization of tower vortex-induced vibration protector
Measure the tower vortex-induced vibration protection module 10 of equal length same size, some long connecting ropes (are used to prevent with tower vortex-induced vibration
Protection unit connects, and realizes the coiled coil of tower vortex-induced vibration protector) and some short connecting ropes (be used to swash with tower whirlpool
Vibration protection device connects, and realizes fixation of the end of tower vortex-induced vibration protector in tower segments) it is applied in combination, and then
It is applicable to different tower segments and different operating situation.In view of transporting, packing, mounting process and processing limitation, it is such as soft
Property connector 11 be standard component, its length is generally integer, such as 2m, thus tower vortex-induced vibration protection module 10 it is flexible even
The length of fitting 11 can not be oversize, can not be too short, preferably 2 meters (m).
When tower whole Transporting or naked tower place a period of time, universal tower vortex-induced vibration protector is worked
Journey is as follows：
First according to tower model, it is determined that suitable shield segment distance (after shield segment distance refers to tower installation, from
Plane is pushed up on flange down to the distance of the bottom of nethermost tower vortex-induced vibration protector), usually 1/3rd
To half tower height, such as tower is highly 90 meters, then shield segment distance is 30 to 50 meters, can be determined within this range
One shield segment distance；It is then determined that the quantity of tower vortex-induced vibration protection module 10；Then each tower vortex-induced vibration is protected
The quick connector 16 of the one end of module 10 is connected to the flexible connecting member of another one end of tower vortex-induced vibration protection module 10
In 11 connection ring 15, until all tower vortex-induced vibration protection modules 10 are linked together.Swash in the tower whirlpool connected
The root long connecting rope 40 of both ends colligation one of vibration protection module 10 and a short connecting rope, or manually will be short using hoisting machinery
Connecting rope one end lifts to tower top flange, and short connecting rope is fixed at the bolt hole of tower top flange.Finally, it is existing
Field personnel pull long connecting rope 40 on ground, and whole whirlpool is swashed into protector is spirally wound on tower wall, and fixed length connects
Rope 40.
When tower is in lifting state, universal tower vortex-induced vibration protector uses as follows：
Wherein, referring to shown in Fig. 5 to 7, according to the length information of protection tower segments 20, determine that tower vortex-induced vibration protects mould
The quantity of block 10.20 long 17.8m of tower segments is such as protected, the length of tower vortex-induced vibration protection module 10 is 2m, then needs to use 9
Tower vortex-induced vibration protection module 10.9 tower vortex-induced vibration protection modules 10 are linked together, using short connecting rope by its
Horizontal colligation is at the upper flange 21 and lower flange 22 of protection tower segments 20, specifically, using short connecting rope by its colligation upper
The bolt hole 23 of flange 21 and the bolt hole 23 of lower flange 22.Due to identical strake height, (i.e. tower vortex-induced vibration is prevented
The height of protection unit) and pitch, the turbulence structure inhibition of 3 screw heads is optimal, therefore during colligation, 3 tower vortex-induced vibrations are prevented
The lashing location of protection unit is uniformly distributed in the circumferencial direction of protection tower segments 20, preferably 120 degree.Each tower vortex-induced vibration is prevented
The cross section of the spoiler 12 of the tower vortex-induced vibration protection module 10 of protection unit is triangle, and height is consistent.
During lifting, when protect tower segments 20 lower flange 22 apart from do not protect 30 certain distance of tower segments when, untie protection
Short connecting rope at the lower flange 22 of tower segments 20, and it is connected with long connecting rope 40.If there is multiple protection tower segments
20, when the lower flange 22 of the protection tower segments 20 of top protects 20 certain distance of tower segments apart from lower section, untie the anti-of top
The short connecting rope protected at the lower flange of tower segments 20, and the short company by its colligation at the upper flange 21 that tower segments 20 are protected in lower section
On splicing, while release colligation of the short connecting rope at the upper flange 21 of lower section protection tower segments 20.When all or part of protection
After tower segments 20 install, whole tower vortex-induced vibration protector colligation is at the bolt hole of the top flange of tower, finally
Pull long connecting rope 40 that whole tower vortex-induced vibration protector is spirally wound in tower on ground, formation is spirally coiled in
The tower vortex-induced vibration protector that can prevent tower vibration in tower.
