Abstract
The utility model relates to the field of ship structures, in particular to a ship wind tower structure. The marine blower structure includes a blower cylinder, wherein a wind vibration preventing device is mounted on the blower cylinder and a plurality of spoilers of the wind vibration preventing device are uniformly distributed along the circular cross section of the blower cylinder, and each spoiler is spirally arranged along the height direction of the blower cylinder. By adopting the device, Karman Vortex can be satisfactorily removed, so as to remove the vibration caused by the Karman Vortex, reduce the risks of damaging the blower cylinder, the blower foundation and the blower mechanical equipment of the blower equipment caused by the wind vibration, and improve the service life of the blower.
Description
Technical field
The utility model relates to the Ship Structure field, a kind of specifically wind tower structure peculiar to vessel.
Background technique
At present, the Oversea wind power generation technology is developed rapidly, and the blower fan electric motor power also increases gradually, makes the height of structure of basic pylon also increase gradually, and the safety of structure has been proposed challenge.
The wind tower of at sea installing does not at present all have good vibration proof device, because the maritime environment condition is more abominable, the wind tower receives that the vibration of the effect generation of wind, wave, stream etc. very easily causes the tired and damage of structure.The vibration of offshore wind turbine mainly be because wind will produce when streaming columniform tower with certain speed down wind and beam wind to vibration; Wind separates in the proceeds posterolateral of tower; The Stagnation Action on surface owing to remain in a standstill alternately produces two in its downstream and shows regular asymmetric toll bar whirlpool.
The toll bar whirlpool causes periodic active force on cylindrical body, when the frequency of whirlpool just can produce resonance near the natural frequency of tower, make beam wind to vibration amplitude than big many of down wind vibration, thereby produce destructive.
Just so, how more easy, economical under this special environment, reduce structural vibrations efficiently, become an important problem in the Oversea wind power generation technology.
The model utility content
A purpose of the utility model is, can reduce the vibration of offshore wind turbine easy, economically, the working life of protection and prolongation wind tower.
The above-mentioned purpose of the utility model and other purposes realize through following technological scheme:
Offshore wind farm vibration proof device comprises the blower fan cylindrical shell, on the said blower fan cylindrical shell windproof vibrating device is housed, and said windproof vibrating device is some flow-disturbing spares of every evenly layout along blower fan cylindrical shell circular section, and said every flow-disturbing spare is along blower fan cylindrical shell short transverse screw arrangement.
Said flow-disturbing spare along the cylindrical shell length direction clockwise or be rotated counterclockwise 180 degree, said flow-disturbing spare is arranged on 2/3rds length areas in the middle of the blower fan cylindrical shell.
Said flow-disturbing spare is four band irons.
Through installing this kind device additional; Can eliminate the generation of toll bar whirlpool well; Thereby eliminate by the caused vibration of toll bar whirlpool, reduced Fan Equipment and possibly cause blower fan tube, blower foundation because of wind-engaging vibrates, reach the risk that the blower fan machinery is destroyed, improved the operating life of blower fan.

Fig. 1 binds round the structural representation after being installed on the blower fan cylindrical shell for a kind of offshore wind farm vibration proof of the utility model anti-wind device shakes;
Fig. 2 distinguished and admirable effect schematic representation during for no windproof vibrating device;
Fig. 3 distinguished and admirable effect schematic representation when windproof vibrating device is arranged;
Wherein: 1, blower fan cylindrical shell; 2, wind-proof device; 4, marine rule is distinguished and admirable; 5, toll bar whirlpool; 6, sinuous flow.
Embodiment
A kind of offshore wind farm vibration proof device; Comprise blower fan cylindrical shell 1; The windproof vibrating device of one cover; Said windproof vibrating device is evenly to arrange four band irons (a, b, c, d) along blower fan cylindrical shell 1 circular section, and the size Selection of band iron decides according to Practical Calculation, and said every band iron is along blower fan cylindrical shell short transverse screw arrangement.Said band iron along the cylindrical shell length direction clockwise or be rotated counterclockwise 180 degree, said flow-disturbing spare is arranged on 2/3rds length areas in the middle of the blower fan cylindrical shell.
Through installing this kind device additional; Can eliminate the generation of toll bar whirlpool well; Thereby eliminate by the caused vibration of toll bar whirlpool, reduced Fan Equipment and possibly cause blower fan tube, blower foundation because of wind-engaging vibrates, reach the risk that the blower fan machinery is destroyed, improved the operating life of blower fan.
