Abstract

The invention relates to a power generator set. The power generator set comprises an engine, a power generator providing electric energy for the engine and a soundproof cover with a soundproof function and a protective function. The soundproof cover is provided with a functional opening and a silencing component located inside the functional opening. The silencing component is provided with a functional channel of a labyrinth structure. According to the power generator set, by arranging the silencing component of the special structure, in combination with the optimization of the structural parameter of the silencing component, the sound absorption area is increased beneficially, the transmission path of noise is prolonged beneficially, noise can form multiple reflections in the noise channel beneficially, more energy is dissipated, the silencing effect is better, dust blockage is facilitated, on the premise of guaranteeing that the silencing component meets normal intake and exhaust requirements of the engine and meeting the heat dissipation performance of the power generator set, the noise reduction of the noise within the wide band range (such as 50-6300Hz) is increased, outwardnoise radiation is reduced, and noise of the power generator set is lowered.

Description

technical field [0001] The invention relates to the field of noise reduction and noise reduction, in particular to a generator set. Background technique [0002] In order to prevent noise pollution, the generator set is encapsulated with a sound insulation cover. At the same time, in order to ensure the normal air intake of the engine and the heat dissipation performance of the generator set, an opening must be made on the sound insulation cover of the engine, which makes the noise radiate from the opening, causing The noise of the generator set is relatively high, which leads to the problem of environmental pollution. For example, installing a muffler between the main sound source (such as an engine, generator, etc.) and the opening of the sound insulation cover can reduce the radiation of noise from the opening, effectively reduce the noise of the diesel generator set, and reduce environmental pollution. In the prior art, the noise reduction effect of the "I" type noise r...
