Description
Technical field
The utility model belongs to wind-driven generator tower antivibration area, and in particular to a kind of above-water wind generator tower
Cylinder damping rope.
Background technique
Wind-driven generator tower may dance in the air under high wind effect because of whirlpool excitation, fluctuating wind, fan blade, fan blade is to tower week
Phase property blocks, the eccentric rotary of transmission shaft etc. causes the substantially vibration of tower, especially offshore wind generating, cushion cap foundation
Also caused tower to be easier to occur substantially to vibrate by Periods beating, leads to tower barrel base cracking, tower fatigue rupture etc.
Accident occurs.
In order to obtain bigger wind energy transformation power, cost of electricity-generating is reduced, the height of tower constantly increases, and tower is easier
Occur substantially, multiple modal vibrations, tower vibration has become the maximum obstacle of tower height growth.Existing blower fan tower barrel vibration damping is main
Using tuning vibration damping, the principle for tuning vibration damping is that a mass block is connected with damper by spring in tower, by rationally setting
The quality of mass block, spring rate and damperparameters are counted, are allowed to form tuned mass damper (TMD), as shown in Figure 1.Fig. 1
In, m is the quality of mass block, and k is spring rate, and c is damper damping, and M is the quality of main structure, and k1 is the main rigidity of structure,
C1 is main structural damping, and F is the power section of wind, fluid equal excitation load suffered by structure, F0For the amplitude of external excitation, ω
For the frequency of external excitation, t is the time.
When tower generation is substantially vibrated, using resonance principle, i.e. the frequency of TMD is consistent with tower vibration frequency, makes TMD
Generation is substantially vibrated, using the balance of shaking force extrinsic motivated of TMD, to inhibit the vibration of structure.The vibration attenuation mechanism of TMD determines
It is only capable of carrying out vibration damping to the single-order frequency of tower, when the frequency of TMD itself and structural vibration frequency departure, the vibration of TMD
Width is reduced rapidly, its effectiveness in vibration suppression is caused to decline rapidly.Meanwhile with the reduction of structural vibration frequency, inertia force is reduced rapidly,
It is likely difficult to balance extrinsic motivated.Towering tower not only has extremely low fundamental frequency, while the vibration of multistage frequency can occur.
Using energy-consumption damper (including various fluid dampers, frcition damper, rubber cushion assembly, metal damper, electricity
The dissipative cells such as eddy current retarder) mode of vibration damping is only capable of being mounted at tower barrel base since damper size itself is small, and
Tower vibration is mainly shown as that beam type vibrates, and tower lower part vibrates very little, and wave crest is in tower, upper section, is only capable of installing
It can not be played in the effect that tower closes on the energy-consumption damper of base position, thus energy-consumption damper can not inhibit towering tower at present
The wind-induced vibration of cylinder.
Summary of the invention
The purpose of this utility model is that providing a kind of utilization tower charming appearance and behaviour vibration for drawbacks described above existing for present technology

Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Referring to fig. 2 to Fig. 7, the above-water wind generator tower damping rope of the present embodiment, it includes being distributed in wind-force
Around the tower 2 of generator 1, it is connected to three sets of damping rope devices of tower 2 and water-bed anchor, three sets of damping rope device edges
Tower 2 inhibits the vibration of tower any direction by 120 ° of central angle installations.Damping rope device includes main rope 3, and main rope 3 is using high
Intensity, high rigidity, corrosion-resistant material such as carbon fiber, glass fibre or other materials are made.3 upper end of main rope is around fixation
After fixed pulley 5 below the inswept face of power-driven generator leaf on the tower wall 4 of home (moving up as far as possible), downwards successively with
The reseting spring device being fixed on tower wall 4 is connected with damper, and 3 lower end of main rope is then solid with the anchor pole 6 of water-bed anchor
It connects.In Fig. 1,7 be blower cushion cap, and 8 be blower foundation stake, and 9 be the water surface.Anchoring underwater device is using uplift pile (for weak rocks
Layer) or anchor pole (for being under water competent bed).
Referring to Fig. 3, reseting spring device includes the pull rod 11 being connect by upper connector 10 with 3 upper end of main rope, referring to figure
4, Fig. 5, upper connector 10 are one with centre bore 101 and multiple lateral opening 102 disks, and 11 upper end of pull rod passes through centre bore
It 101 and is secured with nuts, by the per share steel strand for the main rope 3 that multiply steel strand wires (or other high-intensitive, high rigidity materials) forms
Line passes through lateral opening 102 and is fixed with anchorage.12 He of upper limit plate is successively fixed on the tower wall 4 under upper connector 10
Lower limiting board 13, is fixed with protection cylinder 14 between upper limit plate 12 and lower limiting board 13,11 activity of pull rod passes through upper limit plate 12
Centre bore after be cased with reset spring 15, be fixed with bearing plate 16 on the pull rod 11 of 15 bottom end of reset spring, reset spring 15
