Technical field
The utility model is related to the sound-deadening and noise-reducing equipment technical field of wind turbine, especially relates to a kind of wind turbine and filled with damping and silencing
It sets.
Background technology
There are many wind turbine types, is used in different industries, but can all generate prodigious noise, influences the physical and mental health of people.Separately
Outside, the noise of wind turbine some be because vibrations generate.Existing centrifugal blower denoising device effect is undesirable.
Invention content
In order to solve problems in the prior art, the utility model provides a kind of simple in structure, and wind turbine is filled with damping and silencing
It sets.
Technical solution described in the utility model is as follows：
A kind of wind turbine damping and silencing device, including babinet, the babinet is interior to be equipped with centrifugal blower, the centrifugation wind
Machine on damper, opens up air port, the centrifugation by floor installation on the babinet on the air outlet top of the centrifugal blower
The lateral surface of wind turbine is equipped with sound insulation enclosing, and the sound insulation enclosing is unlimited in the leading flank of centrifugal blower, the sound insulation
Enclosing includes internal layer and abatvoix outer layer, and the first cavity is equipped between the internal layer and abatvoix outer layer, and described first is empty
The abatvoix outer layer inner wall of intracavitary is equipped with the first protrusion, and the internal layer inner wall in first cavity is equipped with the second protrusion,
Second protrusion is upper to be equipped with groove close to abatvoix outer layer inner wall side, and the groove is connected in the first protrusion, described
The second protrusion on be cased with spring, the inner surface undulate of the abatvoix outer layer is uniformly distributed on the abatvoix outer layer
Sound-absorption hole, the inner wall of the babinet are equipped with several grooves, are equipped with muffler in the groove, the babinet it is interior
In the second cavity between wall and outer wall acoustical cotton is equipped with close to outer wall side.
The abatvoix outer layer and the first protrusion is integral structure.
The internal layer and the second protrusion is integral structure.
The internal layer is made of rubber material.
The advantageous effect that technical solution provided by the utility model is brought is：
By the way that sound insulation enclosing is arranged in the outside of centrifugal blower, the noise that can be generated to wind turbine tentatively reduces, and first is empty
Chamber can block the further expansion of sound, the damper of spring, rubber inner layer and wind turbine bottom that can alleviate the vibrations of wind turbine, subtract
Small noise improves the service life of wind turbine, and the muffler on cabinet wall is to the secondary noise reduction of wind turbine, between cabinet wall and outer wall
Acoustical cotton is preferably minimized the noise of wind turbine, improves the working environment in workshop to wind turbine noise reduction three times in second cavity.
