Novel environment-friendly sound insulation cover

Abstract

The invention relates to the technical field of sound insulation devices and discloses a novel environment-friendly sound insulation cover. The sound insulation cover comprises a base; a sound absorption layer is arranged inside a damping layer, and a fan is fixedly connected to the left upper side surface inside the damping layer; the upper end of the base is fixedly connected to a support leg, the upper end of the support leg is fixedly connected to a placing frame, and the outer side of the support leg is provided with a first spring; both ends of the inner part of the placing frame are connected to fixing frames in a sliding manner, and the inner sides of the fixing frames are fixedly connected to extrusion plates. According to the novel environment-friendly sound insulation cover, acoustic kinetic energy of partial noise is weakened through the damping layer, the sound absorption layer further absorbs the noise, and a transmission direction of the partial noise is rebounded on thesound absorption layer through reflecting plates; and a long annular air duct and the plurality of reflecting plates are arranged, so that the noise is fully absorbed by the damping layer and the sound absorption layer, in this way, the noise insulation efficiency is improved, and the purpose of ventilation and heat dissipation of an operation mechanism is achieved.

Description

technical field [0001] The invention relates to the technical field of sound insulation devices, in particular to a novel environment-friendly sound insulation cover. Background technique [0002] With the industrial development of modern society, noise pollution is increasingly occupying the weight of environmental pollution. Noise pollution has become one of the three major environmental pollutions in the world together with air pollution and water pollution. The harm of noise pollution to human body Increasingly, problems such as hearing loss, high incidence of high blood pressure, fatigue and nervous disorders. [0003] The sound insulation cover is a common sound insulation device in the industry. At present, the sound insulation effect of the existing sound insulation cover is not obvious. It is only a simple combination of some sound insulation and noise absorption materials. Although it can achieve the effect of reducing noise, the noise reduction efficiency is low. ...
