Composite module type noise insulation screen

Abstract

The invention relates to a composite module type noise insulation screen. The composite module type noise insulation screen comprises a frame and keels, wherein the keels are uniformly arranged in the horizontal direction and the vertical direction of the inner part of the frame to form a mounting grid; module type noise insulation screens are arranged in the mounting grid; each of the module type noise insulation screens comprises a rainproof punching noise absorbing board arranged on the front, a noise insulation back board arranged on the back, and a pressure-relief noise insulation layer arranged between the rainproof punching noise absorbing board and the noise insulation back board; real-time noise monitoring sensing panels are separately arranged between each of the pressure-relief noise insulation layer and the corresponding noise insulation back board, and are connected with a controller; the controller is arranged on the inner side of the top of the frame; and a monitoring indicator is arranged on the outer side of the top of the frame, and is connected with the controller. The composite module type 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 , has dual effects of pressure release and noise insulation, is convenient to transport and mount.

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 luminous device, which brings certain driving risks to drivers at night. The sound insulation screen is not a modular structure, which is inconvenient for transportation and replacement. It has a single function and cannot play the dual role of pressure relief and sound insulation
