Problems solved by technology

However, the noise produced by the generator set is very large, which directly affects people's life and work. In order to solve this kind of problem, it is necessary to introduce a quiet box for the electric unit in the market, and improve the traditional technology of the quiet box to improve its noise reduction. It is a very important thing to improve the effect and reduce its production cost, so as to further expand the market development of mute speakers

Abstract

The invention discloses a sound attenuated enclosure for a generator set, and relates to the technical field of the generator set. The sound attenuated enclosure structurally comprises a base, an enclosure body wall and an upper cover, wherein the enclosure body wall is arranged above the base, and the upper cover is movably arranged above the enclosure body wall and is used for sealing the enclosure body wall; the enclosure body wall comprises an outer plastic steel layer, a middle sound-absorption foaming layer and an inner damping layer, wherein the edges of the two side enclosure body walls are provided with two push rods which are convenient to push the generator set, the edge of a certain side of the enclosure body wall is provided with a cooling and ventilating pipe which is of an arc shape, and a round hole faces the bottom surface; the bottom of the base is provided with a pulley, the upper cover is provided with an oil inlet on which a seal cover is arranged, and the seal cover is connected with the upper cover through a hinge; a rubber gasket is arranged on an oil inlet, and the push rod is provided with a rubber sleeve capable of increasing the force of friction. The sound attenuated enclosure provided by the invention is simple in structure, and the working noise of the generator set can be greatly reduced.

Description

technical field [0001] The invention relates to a casing of a generator set, in particular to a silent box for a generator set. Background technique [0002] With the development of social science and technology, at present, generator sets are applied in many fields. Generator sets can be used not only as a normal power supply, but also as a backup power supply in case of energy shortage or power outage during peak power consumption. However, the noise produced by the generator set is very large, which directly affects people's life and work. In order to solve this kind of problem, it is necessary to introduce a quiet box for the electric unit in the market, and improve the traditional technology of the quiet box to improve its noise reduction. It is a very important thing to improve the effect and reduce its production cost, so as to further expand the market development of the mute box. Contents of the invention [0003] The invention provides a generator set casing, an...
