Summary of the invention
A kind of wind-power generating unit tower liquid case vibration damping equipment, comprise: liquid case 1, supporting frame 2, liquid 3, described liquid case 1 is fixed on supporting frame 2, and liquid case 1 is built with liquid 3, described liquid case 1 is arranged liquid filling hole 4, outage 6, the position that described liquid filling hole 4 is arranged is higher than outage 6.
Alternately, above-mentioned a kind of wind-power generating unit tower liquid case vibration damping equipment, the position higher than liquid filling hole 4 arranges exhaust port 5.
Alternately, above-mentioned a kind of wind-power generating unit tower liquid case vibration damping equipment, described liquid case 1 is provided with viewing window 7.
Alternately, above-mentioned a kind of wind-power generating unit tower liquid case vibration damping equipment, described liquid case 1 profile is cross or rice shape or cross form.
Alternately, the wind-power generating unit tower of above-mentioned liquid case vibration damping equipment, described vibration damping equipment is fixed on wind-power generating unit tower tower cylinder top by supporting frame 2.
Alternately, above-mentioned a kind of wind-power generating unit tower, at described one or more layers liquid case vibration damping equipment of pylon tower cylinder top layout.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, compare tuned mass damper, TMD, single pendulum vibration damper, this vibration insulating system structure is simple, and the dynamic horizontal pressure utilizing the liquid in liquid case to produce in the process of rocking, to provide damping force, reduces the vibration of pylon.
2, described vibration damping equipment is provided with outage, liquid filling hole, can according to external environment condition at that time, and the liquid volume in time in adjustment liquid case realizes accurate vibration damping.
3, be easy to install and operation, just can be fixedly mounted in wind-power generating unit tower tower cylinder top drum cylinder by supporting frame, the outward appearance of tower cylinder is not affected, and tower cylinder top have enough spaces can install this device.4, because this vibration insulating system structure is simple, the parts related to are less, are convenient to maintenance and the replacing in later stage.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
The structure of a kind of wind power generating set liquid of Fig. 1 case vibration damping equipment and setting type structural representation.
Reference character: 1 be liquid case, 2 be supporting frame, 3 be liquid, 4 be liquid filling hole, 5 be exhaust port, 6 outages, 7 are viewing window, 8 for tower barrel.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
The utility model provides a kind of liquid case vibration damping equipment to reduce the vibration at wind-power generating unit tower top.
A kind of wind-power generating unit tower liquid case vibration damping equipment, comprise liquid case 1, supporting frame 2, liquid 3, liquid case 1 is fixed on supporting frame 2, supporting frame 2 end points and tower barrel 8 affixed, liquid case 1 is built with a certain amount of liquid 3.Liquid case has viewing window 7, liquid case is provided with liquid filling hole 4, outage 6, exhaust port 5.
Principle of the present utility model is: it be utilize the liquid in liquid case to produce in the process of rocking dynamic horizontal pressure to provide damping force, reduce the vibration of pylon.
Described liquid case 1 profile is the analogous shapes such as cross, rice shape, cross form.Determine by theoretical or test the size that liquid case is suitable, and inject the degree of depth of liquid, make the slosh frequency of liquid case 1 internal liquid and tower oscillation frequency close to or equal.This type of liquid case not only can reduce the transverse vibration of tower cylinder, and can reduce the torsional vibration of tower cylinder.
Described vibration damping equipment can be fixed on wind-power generating unit tower top, also can combinationally use, can according to measured result at one or more layers liquid case vibration damping equipment of tower cylinder top layout.Because liquid case vibration damping equipment described in the utility model is arranged in tower top tower cylinder, the outward appearance of tower cylinder is not affected, and tower cylinder top has enough spaces can install this device.
During use, open liquid case liquid filling hole 4 and exhaust port 6, inject liquid by liquid filling hole 4, gas is got rid of from exhaust port 5, is checked the degree of depth injecting liquid, stop when the degree of depth reaches required value by viewing window 7.When liquid depth exceeds, unnecessary liquid can be released by outage 6.Closedown liquid filling hole 4, outage 6, exhaust port 5 after fluid injection completes.In addition, can according to external environment condition at that time, the liquid volume in time in adjustment liquid case 1 realizes accurate vibration damping. and described liquid case 1 is horizontally fixed on supporting frame 2, and support frame as described above 2 keeps level, and supporting frame 2 end points is fixed on tower barrel 8.
