Embodiment 1

[0028] Example 1: Combining figure 1 and figure 2 Describe the sound barrier of the present invention, which is located on both sides of the road, and is formed by a plurality of sound barrier units 10 arranged in sequence along the road extension direction, and the sound barrier unit 10 includes:

[0029] The frame body is a rectangular frame structure formed by connecting two horizontal beams 1 arranged at intervals and two vertical columns 2 arranged at intervals vertically;

[0030] A plurality of blades 3 are vertically spaced and arranged continuously in the frame body, and the two ends of each blade 3 are movably connected to the frame body to block the noise transmission of the driving vehicle 50. The shape of the blade 3 in this embodiment is preferably long shape;

[0031] The blade angle adjustment system is connected with a plurality of blades 3 and is used to control the rotation of the blades 3 along their axes.

[0032] The sound barrier of the present inven...

Embodiment 2

[0039] Example 2: The sound-absorbing and insulating panels of traditional sound barriers are mostly perpendicular to the road extension direction, and the traffic noise barrier for normal phase incident transmission is better. However, there is a certain angle between the facades of the buildings on both sides of the road and the road extension direction In the case of traffic noise barriers, the effect of the traffic noise barrier is relatively poor. figure 1 Illustrate the using method of sound barrier of the present invention, concrete steps are as follows:

[0040] The sound barrier units 10 are installed sequentially along the extension direction on both sides of the road, and the blades 3 are controlled to rotate horizontally around the axis through the blade angle adjustment system, so that the multiple blades 3 of the sound barrier unit 10 are parallel to the facade of the nearest building , so that the noise of the driving vehicle 50 can be directed to the sound barr...

Embodiment 3

[0041] Example 3: Binding figure 1 and figure 2 Illustrate the using method of sound barrier of the present invention, concrete steps are as follows:

[0042] S1: Install the sound barrier unit 10 sequentially along the extending direction on both sides of the road;

[0043] S2: the noise sensor 20 senses the noise that the motor vehicle on the road sends, and the data information of the noise is sent to the signal processor 30, and the signal processor 30 compares the real-time noise data with the noise setting value and provides the blade 3 Rotate the angle signal, and then control the angle adjustment device to drive multiple blades 3 to rotate, so as to reduce the impact of traffic noise on the surrounding environment; figure 2 As shown, when the real-time noise is greater than the noise setting value, the angle between the blades 3 of the sound barrier unit 10 and the road extension direction decreases, and when the real-time noise is smaller than the noise setting va...

Abstract

A sound barrier and a using method thereof of the present invention relate to the technical field of road traffic environmental protection. Aiming at the problem that the existing sound barrier has a large dead weight and requires regular maintenance or replacement, which is time-consuming and labor-intensive. The sound barrier is located on both sides of the road, and is composed of multiple sound barrier units arranged in sequence along the road extension direction. The sound barrier unit includes: a frame body, which is a frame structure connected by at least two beams and at least two columns; A plurality of blades are arranged at intervals and arranged continuously in the frame body, and the blades are movably connected to the frame body; a blade angle adjustment system is connected with the blades and used to control the rotation of the blades along their axes. How to use: install sound barriers on both sides of the road along its extension direction; the noise sensor senses the noise emitted by driving vehicles, and transmits the noise data to the signal processor, which compares the real-time noise data with the noise set value and calculates The rotation angle signal of the blade is given, and then the angle adjustment device is controlled to drive multiple blades to rotate.

Description

technical field [0001] The invention relates to the technical field of road traffic environmental protection, in particular to a sound barrier and a use method thereof. Background technique [0002] With the rapid development of the economy, the progress of urbanization is accelerating, and the transportation methods such as highways, railways, and urban viaducts have been developed rapidly. These roads will inevitably pass through densely populated residential areas during construction, and the traffic noise generated by the road will cause serious damage to the surrounding areas. The life and work of the residents have brought some troubles. In view of traffic noise pollution, the main means of noise reduction at home and abroad is to set up sound barriers along the road, which can reduce noise from the perspective of blocking the sound transmission path. The traditional sound barrier is mainly composed of steel structure columns and sound-absorbing and insulating panels....
