Embodiment 1

[0028] Example 1: Combination figure 1 with figure 2 It is explained that the sound barrier of the present invention is located on both sides of the road and is formed by a plurality of sound barrier units 10 arranged in sequence along the extending direction of the road. The sound barrier unit 10 includes:

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

[0030] A plurality of blades 3 are arranged vertically at intervals and continuously arranged in the frame body, and both ends of each blade 3 are movably connected to the frame body to block the noise propagation of the traveling vehicle 50. The shape of the blade 3 in this embodiment is preferably elongated shape;

[0031] The blade angle adjustment system, which is connected with a plurality of blades 3, is used to control the rotation of the blades 3 along its axis.

[0032] The sound barrier of the p...

Embodiment 2

[0039] Example 2: The sound-absorbing and insulating panels of traditional sound barriers are mostly perpendicular to the direction of road extension, and the effect of traffic noise barriers transmitted by normal incidence is better. However, there is a certain angle between the facades of the buildings on both sides of the road and the direction of road extension Circumstances, the effect of traffic noise barriers is poor, the following combination figure 1 To illustrate the use method of the sound barrier of the present invention, the specific steps are as follows:

[0040] Install the sound barrier unit 10 in sequence along its extension direction on both sides of the road, and control the blade 3 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 traveling vehicle 50 can be directed to the sound barrier unit 10...

Embodiment 3

[0041] Example 3: Combination figure 1 with figure 2 To illustrate the use method of the sound barrier of the present invention, the specific steps are as follows:

[0042] S1: Install sound barrier units 10 on both sides of the road in sequence along its extension direction;

[0043] S2: The noise sensor 20 senses the noise emitted by the motor vehicle driving on the road, and transmits the data information of the noise to the signal processor 30. The signal processor 30 compares the real-time noise data with the noise setting value and gives the information of the blade 3 Rotate the angle signal, and then control the angle adjustment device to drive the rotation of multiple blades 3 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 extending direction of the road decreases. When the real-time noise is less ...

Abstract

The invention discloses a sound barrier and a use method thereof and relates to the technical field of highway traffic environmental protection. The invention aims at solving the problems that an existing sound barrier has greater dead weight, needs periodic maintenance or change and consumes a great deal of time and labor. Sound barriers are positioned on two sides of a road and are formed by sequentially arraying a plurality of sound barrier units along the extending direction of the road; each sound barrier unit comprises a frame body, a plurality of blades and a blade angle adjusting system, wherein the frame body has a framework structure formed by connecting at least two cross beams and at least two upright posts; the plurality of blades are arranged in a spaced manner, are continuously arranged in the frame body, and are movably connected to the frame body; the blade angle adjusting system is connected with the blades and is used for controlling the blades to rotate along the axis of the blade angle adjusting system. The use method comprises the following steps: the sound barriers are arranged on two sides of the road along the extending direction of the road; a noise transducer senses noises given out by running vehicles and transmits noise data to a signal processor; the signal processor compares real-time noise data with a noise set value and giving out a rotating angle signal of the blades, and further controls the angle adjusting device to drive the plurality of 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 method of use thereof. Background technique [0002] With the rapid development of the economy, the progress of urbanization is accelerating, and the highways, railways, urban elevated and other transportation methods have been rapidly developed. These roads inevitably pass through densely populated residential areas during construction, and the traffic noise generated by the roads is nearby. The life and work of the residents brought certain difficulties. In view of traffic noise pollution, the main noise reduction method at home and abroad is to set up sound barriers along the road to reduce noise from the perspective of blocking the sound propagation path. The traditional sound barrier is mainly composed of two parts: a steel structure column and a sound-absorbing and insulating screen. The steel structure column is the main forc...
