Device for silencing, ventilation and light collection

Abstract

The invention discloses a device for silencing, ventilation and light collection. The device comprises a quadrangle silencing frame filled with a silencing material, wherein interior of the silencing frame is divided into a ventilation and silencing room and a light collection and silencing room; the ventilation and silencing room is divided into three successively connected rooms including a first room, a second room and a third room, and the first room and the third room are opened and the second room is sealed on the face of the ventilation and silencing room located outdoors; the indoor side of the ventilation and silencing room is closed, and connection edges between the first room and third room and the second room are set as ventilated grates or nets; at joints of the ventilation and silencing room and the light collection and silencing room, the first room and the third room are sealed by silencing edges, and the second room is open; and an outer window body is disposed on the outdoor face of the light collection and silencing room, and an inner window body with an openable structure is disposed on the face towards indoors. According to the invention, light collections effects are the same as light collection effects of a common window; dual-layer window sealing is used; sound isolation effects are better; ventilation is quick; ventilation effects are good; the silencing structure achieves perfect silencing effects; the structure is simple; the cost is low; and use is convenient.

Description

technical field

[0001] The invention relates to a noise reduction, ventilation and daylighting device, which is mainly used for noise reduction, ventilation and daylighting at the windows of workshops and venues. Background technique

[0002] Noise refers to the sound produced when the sounding body vibrates irregularly. Sound is produced by the vibration of objects and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. Generally speaking, noise pollution refers to human-caused.
