Generator set with sound insulation type ventilation system

Abstract

The invention discloses a generator set with a sound insulation type ventilation system. The generator set comprises a ventilation plate with grids, wherein ventilation holes and audio reflection molded sheets are distributed on the grids, the audio reflection molded sheets are in one-to-one correspondence with the ventilation holes, fixed on the outer sides of the ventilation holes and used for reflecting audio out of the ventilation holes, and ventilation channels are formed between the audio reflection molded sheets and the ventilation holes. According to the generator set, the audio reflection molded sheets are arranged outside the ventilation holes of the grids of a sound insulation cover, noise, transmitted from the interior, of the generator set are partially reflected, consumed andtransmitted back into the ventilation holes, so that the noise is reduced; and due to the molded sheets, the ventilation in the generator set is carried out without directly passing through the ventilation holes, and an inflection point is formed, so that the wind speed is reduced, the air flow noise is reduced, and finally the purpose of noise reduction is achieved; and the sound insulation effect can be well achieved, the noise can be reduced within the required standard on the existing basis, the ventilation effect of the generator set can be guaranteed, and meanwhile, the ventilation noise formed in the ventilation process can be reduced, the structure is simple, and the appearance of the whole set and the use are not influenced.

Description

technical field [0001] The invention relates to the accessory parts of the generator set and the generator set itself, in particular to a generator set with a sound-proof ventilation system. Background technique [0002] As a backup power source, generator sets have played a role that cannot be ignored in various fields of national production and life. Generator sets have various models and power according to different needs. Such as diesel generator sets, and the implementation of small structures, the noise it produces has reached more than 100dB (A), which will cause noise pollution to the environment, thus affecting its popularization and use. In order to solve the above problems, the diesel generator set is covered with a sound insulation cover, and the noise transmitted outwards is reduced as much as possible through the sound insulation cover, so as to reduce the noise of the generator set. However, the operation of the generator set will generate a lot of heat, and...

AI Technical Summary

Problems solved by technology

However, after the vent is opened, the noise reduction effect of the sound insulation cover is relatively poor, and the vent itself will also generate noise during the ventilation process, which will be superimposed with the noise of the generator set to form noise pollution
