The utility model has following advantage:
1, this device does not need energy to input.Wherein, the rotational of blade changes wind field blast, and damping unit can consume wind energy, is combined like this and can play good wind resistance effect, and protection roofing is not damaged.
When 2, building house, because of considering the impact of roof system form for wind loading rating power, and several specific roof system form need not be confined to, the adverse effect that installation damping energy dissipation wind-proof device brings to make up roof system form deficiency can be considered.
3, the utility model simple structure, part is less, and simply, applicability is strong, and cost is low and easy to maintenance, effectively can improve the seismic wind resistance of structure, has wide popularization market and application prospect for making and installation process.
