Abstract
The utility model discloses a wind generating set noise reduction air duct which comprises a ventilating duct and a noise reduction air duct, wherein one end of the noise reduction air duct is matched, connected and fixed with an air outlet of the ventilating duct, and the other end of the noise reduction air duct adopts a corrugate shape. The noise reduction air duct is arranged at an outlet of a wind generating set ventilating duct and can reduce turbulent flow produced during mixing of air flow in the ventilating duct and a cooling duct of a wind generating set, so that noise produced by a noise source in the wind generating set ventilating duct is reduced. The wind generating set noise reduction air duct is simple in structure, efficient, reliable and convenient to operate.
Description
Technical field
The utility model relates to wind power generator field, relates in particular to a kind of wind power generating set noise reduction air duct.
Background technique
The noise of wind power generating set mainly comes from many-side, and wherein a kind of is the aerodynamic noise of the mobile generation of ventilation, radiation system high velocity air.When high velocity air mixes with air, thereby owing to existing larger speed difference to cause strong turbulent flow, portion of energy produces with the form radiation of acoustic energy.General way is to adopt change structure reduce the generation of noise and absorb two kinds of means of noise.Prior art is mainly to take to install additional in ventilation duct to absorb noise device as main, and low unreliable, the inconvenient operation of this technological means efficiency, can not fundamentally reduce the generation of noise or minimizing noise.
Model utility content
The purpose of this utility model is to overcome above defect, and a kind of high efficient and reliable, easy to operate wind power generating set noise reduction air duct are provided.
The technological scheme that the utility model solves the problems of the technologies described above is: a kind of wind power generating set noise reduction air duct, it comprises ventilation duct, also comprise noise reduction air duct, one end of noise reduction air duct and the exhaust outlet of ventilation duct match and are connected and fixed, the other end of noise reduction air duct is corrugated, and the corrugated of the noise reduction air duct the other end is equally distributed ripple profile of tooth or zigzag fashion or star tooth ripples structure.
Technique effect of the present utility model is, in wind power generating set ventilation duct outlet port, a noise reduction air duct is set, wind power generating set can be ventilated, the turbulent flow producing when air-flow mixes in hot channel reduces, thereby reduce the noise that the noise source place in wind power generating set ventilation duct produces, the utility model is simple in structure, high efficient and reliable, easy to operate.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representation.
Fig. 3 is the utility model embodiment 3 structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment 1: as shown in Figure 1, a wind power generating set noise reduction air duct, it comprises ventilation duct 1, also comprises noise reduction air duct 2, the exhaust outlet of one end of noise reduction air duct 2 and ventilation duct 1 matches and is connected and fixed, and the other end of noise reduction air duct 2 is equally distributed ripple tooth-shape structure.
Embodiment 2: as shown in Figure 2, a wind power generating set noise reduction air duct, it comprises ventilation duct 1, also comprises noise reduction air duct 3, the exhaust outlet of one end of noise reduction air duct 3 and ventilation duct 1 matches and is connected and fixed, and the other end of noise reduction air duct 3 is equally distributed zigzag structure.
Embodiment 3: as shown in Figure 3, a wind power generating set noise reduction air duct, it comprises ventilation duct 1, also comprises noise reduction air duct 4, the exhaust outlet of one end of noise reduction air duct 4 and ventilation duct 1 matches and is connected and fixed, and the other end of noise reduction air duct 4 is equally distributed star tooth ripples structure.
Principle of the present utility model is, utilize vortex generator principle, in wind power generating set, draw together ventilation duct 1 exhaust outlet and install the noise reduction air duct with special shape additional, the air air that part high velocity air is very low with speed in the process of mixing that exhaust outlet place high velocity air is very low with speed is first mixed, thereby the turbulent flow that generating portion is less or in the less turbulent flow of the inner generating portion of high velocity air, make like this energy that air that high velocity air is very low with speed discharges when fully mixing reduce, avoid air that high velocity air is very low with speed directly to mix and cause strong turbulent flow, thereby low noise radiation energy is fallen.
In the utility model, noise reduction air duct is not limited in shown in embodiment, as long as meet the utility model principle, all at protection domain of the present utility model.
Claims (4)
1. a wind power generating set noise reduction air duct, it comprises ventilation duct, it is characterized in that, also comprises noise reduction air duct, and one end of noise reduction air duct and the exhaust outlet of ventilation duct match and are connected and fixed, and the other end of noise reduction air duct is corrugated.
2. a kind of wind power generating set noise reduction air duct according to claim 1, is characterized in that, described ripple is equally distributed tooth ripple.
