Generator set

Abstract

The invention relates to a generator set. The generator set comprises a generator assembly and a sound insulation hood arranged outside the generator assembly in a covering mode. The sound insulationhood comprises a sound insulation hood body and an access door arranged on the sound insulation hood body. A functional opening is formed in the access door. A plurality of waterproof noise-elimination pieces are vertically arranged at the functional opening in parallel, and a functional channel is formed between every two adjacent waterproof noise-elimination pieces. Each adjacent waterproof noise-elimination piece comprises a waterproof part and a noise-elimination part, wherein the waterproof part is located on the outer side of the sound insulation hood body and inclines in the direction of the functional channel to guide a water flow out of the sound insulation hood body, and the noise-elimination part is located on the inner side of the waterproof part and is used for eliminating noise. According to the generator set, rainwater can be prevented from entering the sound insulation hood while good air intake and heat dissipation are guaranteed, so that the generator set is protected; and meanwhile, the noise elimination quantity within a broadband range is improved, outward radiation of noise is reduced, the noise of the generator set is effectively reduced, and pollution of thenoise to the environment is reduced.

Description

technical field [0001] The invention relates to the sound insulation field of generator sets, in particular to a generator set. Background technique [0002] The sound insulation cover of the generator set is a device to control the noise of the generator set by means of sound insulation, sound absorption, noise elimination, ventilation, etc., so as to effectively block the noise from spreading and reduce the impact of noise on the environment. [0003] Existing generator sets, in order to prevent noise pollution, need to be sealed with sound insulation cover, in order to facilitate the maintenance of components inside the generator set, the air intake end of the sound insulation cover is often provided with an inspection door; and in order to ensure the normal operation of the generator set Air and heat dissipation must be opened on the inspection door; and in order to control the noise level of the unit, the opening on the inspection door needs to adopt a special structure...

Problems solved by technology

[0003] Existing generator sets, in order to prevent noise pollution, need to be sealed with sound insulation cover, in order to facilitate the maintenance of components inside the generator set, the air intake end of the sound insulation cover is often provided with an inspection door; and in order to ensure the normal operation of the generator set Air and heat dissipation must be opened on the inspection door; and in order to control the noise level of the unit, the opening on the inspection door needs to adopt a special structure to prevent the noise from leaking directly. Energy dissipation achieves the purpose of noise reduction. However, the noise reduction effect of this method of only reflecting energy consumption is not good, and it cannot effectively block the noise from spreading to reduce the impact of noise on the environment.
