Abstract
The utility model provides a large -scale generating set's active noise reduction silence device, it includes generating set installation silence room, its characterized in that of: at indoor controller, loudspeaker and the noise collector of being provided with of generating set installation silence, the signal input part of noise collector and controller is connected, and the signal output part and the loudspeaker of controller are connected, and the noise collector transmits the noise signal of collection for the controller, and the controller carries out analysis processes according to received noise signal to produce the sound wave reverse completely with noise signal, send sound wave propagation for loudspeaker, make sound wave and noise cancel each other out. Since the technical scheme is used, the utility model has the advantages of simple structure and convenient to use, it adopts the active noise reduction technique, can gather the noise that generating set sent to according to the noise manufacturing send with the noise on the contrary to the sound wave, make the sound wave cancel each other out of noise and manufacturing, with the noise of eliminating the overwhelming majority, easily control.
Description
Technical field
The utility model relates to a kind of technical field of power generation, particularly a kind of noise reduction silencing apparatus of generator.
Background technology
Existing genset is generally all mounted in the installation room of sealing, as the installation room at the generator place on boats and ships, then noise is larger, or small-sized generator case, quiet cotton is pasted at box house, the noise transmission that genset sends on quiet cotton, by quiet cotton absorption portion noise, to reduce the partial noise of genset, noise amount of cancellation is less, and genset still exists larger noise.
Utility model content
The utility model a kind of active noise reduction silencing apparatus of Generator Set is provided, it can gather the noise that genset sends, and according to noise manufacture send contrary with noise to sound wave, the sound wave of noise and manufacture is cancelled out each other, with eliminate the overwhelming majority noise.
The utility model adopts following technical scheme to realize, it comprises genset and installs quiet room, install in quiet room at genset and be provided with controller, loudspeaker and noise gathering device, noise gathering device is connected with the signal input part of controller, the signal output part grasping device processed is connected with loudspeaker, the noise signal of collection is transferred to controller by noise gathering device, controller carries out analyzing and processing according to the noise signal received, and produce the sound wave completely reverse with noise signal, sound wave is passed to loudspeaker send, sound wave and noise are cancelled out each other.
A large amount of noises can be sent in genset operational process, now, noise gathering device is by synchronous acquisition noise and pass to controller, and controller carries out after receiving noise signal analyzing, processing immediately, and produces the sound wave completely reverse with the noise signal gathered according to noise signal, the sound wave produced is passed to loudspeaker and sends by controller, cancelled out each other by reverse sound wave and noise, to eliminate the noise of the overwhelming majority, by the elimination initiatively to noise, easy to use, be easy to control.
Owing to have employed technique scheme, structure of the present utility model is simple and easy to use, it adopts active noise reduction techniques, the noise that genset sends can be gathered, and according to noise manufacture send contrary with noise to sound wave, the sound wave of noise and manufacture is cancelled out each other, to eliminate the noise of the overwhelming majority, is easy to control.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows.

Genset being arranged on group of motors installs in quiet room 1, genset 6 can send a large amount of noises in operational process, now, noise gathering device is by synchronous acquisition noise and pass to controller, controller carries out after receiving noise signal analyzing, processing immediately, and produce the sound wave completely reverse with the noise signal gathered according to noise signal, the sound wave produced is passed to loudspeaker and sends by controller, cancelled out each other by reverse sound wave and noise, to eliminate the noise of the overwhelming majority, by the elimination initiatively to noise, easy to use, be easy to control.
As shown in Figure 1-2, the sidewall of genset installation quiet room 1 is provided with acoustical cotton 5.Acoustical cotton can be arranged on genset in the mode of pasting and install the sidewall of quiet room, can absorption portion noise by acoustical cotton, increases the effect of noise reduction.
As shown in Figure 1-2, described noise gathering device 4 is noise reduction microphone.Carry out synchronous recording noise by noise reduction microphone, to ensure the accuracy of identification of controller to noise, be conducive to manufacturing reverse sound wave.
As shown in Figure 1, conveniently gather noise, reduce other noise, noise gathering device 4 is arranged on the top that quiet room installed by genset.
As shown in Figure 1, in order to the better effects if making reverse sound wave and noise cancel out each other, loudspeaker 3 are one, are arranged on genset and install quiet room 1 top or sidewall.
As shown in Figure 2, in order to the effect making reverse sound wave and noise cancel out each other reaches best, loudspeaker 3 are two, are arranged on genset respectively and install in the both sides at quiet room 1 top or the two opposite side walls of genset installation quiet room 1.
