Noise insulation screen

Abstract

The invention relates to a noise insulation screen. A main body of the noise insulation screen consists of a vertical section noise barrier and an oblique section noise barrier, wherein an included angle between the vertical section noise barrier and the oblique section noise barrier is 150-170 degrees, and the length of the oblique section noise barrier is one fifth to one third of that of the vertical section noise barrier; the main body of the noise insulation screen comprises a framework; a foamed aluminum board is arranged on the front of the framework; a noise insulation back board is arranged on the back of the framework; a real-time noise monitoring sensing panel is arranged on the inner side of the foamed aluminum board, and is connected with a controller; the controller is arranged on the inner side of the top of the framework; a monitoring indicator is arranged on the outer side of the top of the framework, and is connected with the controller; and a night light device is arranged at the lower part of the framework. The novel noise insulation screen disclosed by the invention can realize the effects of monitoring noise in real time, and reminding that the noise insulation screen is damaged, and has night light promotion, large diffraction angle and good noise insulating effect.

Description

technical field [0001] The invention relates to a sound insulation device, in particular to a sound insulation screen. Background technique [0002] With the progress of society and the development of cities, people's living standards continue to improve, and urban traffic has become the most closely related issue to us. The construction of a large number of expressways and the opening of urban light rail and high-speed railway have brought great convenience to our travel, but at the same time residents living near these expressways, light rail and high-speed rail suffer from the impact of traffic noise. In order to improve the living environment of citizens, relevant departments have installed various sound-absorbing barriers on both sides of the road and along the light rail and high-speed rail. [0003] The existing sound insulation screens are not equipped with noise real-time monitoring devices and monitoring indicators, so it is impossible to detect damaged sound insu...

AI Technical Summary

Problems solved by technology

[0003] The existing sound insulation screens are not equipped with noise real-time monitoring devices and monitoring indicators, so it is impossible to detect damaged sound insulation screens in time, and cannot be replaced in time after damage. The lower part of the sound screen is not equipped with a night light device, which brings certain driving risks to night drivers. The ratio and angle of the vertical section and the inclined section of the sound barrier are unreasonable. After the noise passes through diffraction, it will still cause inconvenience to nearby residents.
