Abstract
The utility model relates to a mass damping system of a wind driven generator unit. The mass damping system comprises a cabinet, a tower platform and a damping weight, wherein the damping weight is dispersed and arranged in the cabin or/and on the tower platform. According to the mass damping system, by using sand, soil and water in a wind field as materials, the sand and the soil are loaded into a sand bag or water is loaded into a water tank and sealed, and is dispersed in the cabin or/and on the tower platform, and according to knowledge of structural dynamics, the mass characteristic of a tower changes and the vibration frequency of the tower is reduced, the sand or water absorbs the vibration energy of the wind driven generator unit, and thus the vibration characteristic of the unit is changed, and the amplitude is greatly lowered. The mass damping system acts according to the circumstances, uses local materials, and is low in cost.
Description
Technical field
The utility model relates to the vibrationproof vibration insulating system, relates in particular to a kind of Tuned mass damper system of wind-driven generator unit.
Technical background
The wind-driven generator unit generally consists of blade, wheel hub, generator, cabin, and unit is worked under the random outside wind regime of complexity.The vibration of flexible tower cylinder, the vibration of impeller is the focus of paying close attention to always.Unit vibration is generally low-frequency vibration, can cross point of resonance by improving wind speed round.Due to shape with a varied topography, the restriction of installing space, wake effect, tower shadow effect and turbulent extent are high, and deviation appears in the point of resonance of small part unit, during control, more difficult assurance.Current damping modes mainly adopts the raising structural rigidity, such as welding on stack shell is supported, and the oblique pull steel cable, affixed with the pre-buried support in ground, this mode needs special steel, and the field work difficulty is larger.
The model utility content
The purpose of this utility model is to provide a kind of and draws materials conveniently, realizes the Tuned mass damper system of simple a kind of wind-driven generator unit.
The purpose of this utility model is achieved through the following technical solutions: a kind of Tuned mass damper system of wind-driven generator unit, and it comprises cabin, pylon platform, also comprises damping weight, described damping weight divides and intersperses among in cabin or/and on pylon platform.
The weight of described damping weight is 5% to 10% of unit weight.
Described damping weight is sand pocket.
Described damping weight is sealing radiator.
Described damping weight is sand pocket and sealing radiator.
Effect of the present utility model is that, with the sandstone of wind field, earth and water are as material, by sandstone and the earth sand pocket of packing into, or, by water pack into water tank sealing, it is dispersed in cabin or/and on pylon platform, according to structural dynamic, gain knowledge, at this moment the mass property of tower cylinder changes, and the vibration frequency of tower cylinder descends, sandstone or water absorb the vibrational energy of wind power generating set, thereby change the vibration characteristics of unit, greatly reduce amplitude, and suit measures to local conditions, gather materials on the spot, with low cost.
The accompanying drawing explanation
Fig. 1 is the utility model one embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1, it comprises blade 1, impeller 2, generator 3, cabin 4, platform 5, sand pocket or sealing radiator 6 and tower cylinder 7, at first get sand pocket or sealing radiator 6 ready, at other sandstone, silt or the water obtained of blower fan, through conical thin-wall tower cylinder 7, sand pocket or sealing radiator 6 are disperseed to be placed in tower barrel platform 5 and cabin 4.The 200 tons of heavy-duty machine groups of take are example, and desirable unit weight 5% is as the gross weight of sandbag or water tank, if each sand pocket can fill the 500kg sandstone, each water tank can fill 500kg water, and to add the upper water box number be 20 to get final product to the sand pocket number so, and the quantitative proportion of sandbag and water tank is not done requirement.
Above sandbag or sealing radiator 6 also can only be placed on tower barrel platform 5, or only are placed in cabin 4.
