Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a wind-resistant sound barrier. Background Art

[0002] A sound barrier is an acoustic baffle specifically designed to stand between a noise source and a sound-receiving point. It is usually designed for a specific noise source and a specific protected location. Sound barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. They are divided into pure sound-insulating reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation.

[0003] Since sound barriers are generally installed on highways, expressways, and elevated roads without surrounding obstructions, they will be impacted by relatively strong winds. When the weather is poor and the wind is strong, due to the large area of the connected sound barriers, the wind cannot pass through well, and the wind force to be resisted is also very large. If the support strength of the sound barrier is insufficient, it is easy to become loose and damage the sound barrier. In order to improve the wind resistance of the sound barrier and allow the wind to pass through easily, this solution proposes a wind-resistant sound barrier. Summary of the Invention

[0004] The purpose of the utility model is to address the problem in the background art that the area of the connected sound barriers is large, the wind force to be resisted is also large, and if the strength of the sound barrier is insufficient, it is easy to damage the sound barrier, and to propose a wind-resistant sound barrier.

Detailed implementation mode

[0020] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] As Figure 1 shown, a wind-resistant sound barrier proposed by the present utility model includes a base 1, a support mechanism 2 is arranged on the base 1, a rotation device for wind use is arranged on the support mechanism 2, a reset device for resetting the vertical plate 207 is arranged on the support mechanism 2, the rotation device is used to rotate the vertical plate 207, a wind resistance device 3 is arranged on the support mechanism 2, a first suspension plate 303 and a second suspension plate 304 for air outlet are arranged on the wind resistance device 3, and both the first suspension plate 303 and the second suspension plate 304 can rotate at a fixed angle.

[0023] As Figure 3 shown, the support mechanism 2 includes a support plate 201, the support plate 201 is welded to the base 1, a rectangular hole is opened on the support plate 201, the rectangular hole is used for the subsequent passage of wind force, playing a role in wind resistance, a group of limiting grooves are opened on the support plate 201, the limiting grooves are used for the subsequent installation of plates, a limiting hole 202 is opened on the support plate 201, a circular groove 203 is opened on the support plate 201, and the base 1 is sleeved on the guardrails on both sides of the elevated road, thereby fixing the base 1.

[0024] As Figure 4As shown in the figure, the rotating device includes a limiting post 204 rotatably connected to the limiting hole 202. A group of connecting blocks 205 are fixedly connected to the limiting post 204. A group of first rings 206 are welded to the two connecting blocks 205. A vertical plate 207 is fixedly connected to the limiting post 204. The vertical plate 207 is fitted into the rectangular hole on the support plate 201. A vertical shaft 208 is fixedly connected to the vertical plate 207. The vertical shaft 208 is fitted into the circular groove 203. The vertical plate is vertically installed on the support plate 201. At this time, there is a gap between the vertical plate 207 and the support plate 201, but it can well isolate the lateral propagation of sound. When the wind force is large, the wind blows towards the vertical plate 207. Under the action of the vertical shaft 208 and the limiting post 204, the vertical plate 207 will be driven to rotate, so that a rectangular air outlet appears between the vertical plate 207 and the support plate 201, so that the air can pass through, thus playing a role in wind resistance.

[0025] As Figure 5 shown, the reset device includes a tension spring 209 sleeved on the first ring 206. The other ends of the two tension springs 209 are sleeved with a second ring 210. The two second rings 210 are welded to the box body 211. A group of limiting blocks 212 are fixedly installed on the two box bodies 211. The two limiting blocks 212 are in contact with the connecting blocks 205. When the wind stops, under the action of the pulling force of the tension spring 209 on the first ring 206 on the limiting post 204, it will reset to the normal state. At this time, the air outlet between the vertical plate 207 and the support plate 201 will be closed, forming a gap, so that the lateral propagation of sound can be isolated again.

[0026] As Figure 5 shown, the box body 211 is fixedly installed with a cover plate 213 by bolts. The installation of the cover plate 213 can make the box body 211 a closed space, thus protecting the internal components.

[0027] As Figure 2 shown, the wind resistance device 3 includes a fixed frame 301. The fixed frame 301 is slidably installed in the limiting groove on the support plate 201. The fixed frames 301 are stacked and installed in the limiting groove on the support plate 201. The fixed frames 301 are pressed against each other, so that the connection is tighter.

[0028] As Figure 2As shown, a group of arc-shaped panels 302 are fixedly installed on the fixed frame 301. When the wind force is large, after blowing against the arc-shaped panels 302, the wind force will move towards both sides of the arc-shaped panels 302, thereby changing the flow direction of the wind force. A first suspension plate 303 is hinged on the fixed frame 301, a second suspension plate 304 is hinged on the fixed frame 301, and two sets of rectangular holes are opened on the fixed frame 301. Both the first suspension plate 303 and the second suspension plate 304 are installed in the rectangular holes. When there is no wind force, the first suspension plate 303 and the second suspension plate 304 are vertically installed in the rectangular holes opened on the fixed frame 301, thereby effectively isolating the lateral transmission of sound. When the wind force is large, the first suspension plate 303 and the second suspension plate 304 will be lifted by the wind force, thereby exposing the rectangular holes opened on the fixed frame 301, so that the wind can pass through, thus achieving the effect of wind resistance.

[0029] In this embodiment, when there is a gap between the vertical plate 207 and the support plate 201 under normal conditions, but it can effectively isolate the lateral transmission of sound. When the wind force is large, the wind blows against the vertical plate 207. Under the action of the vertical shaft 208 and the limit post 204, the vertical plate 207 will be driven to rotate, so that a rectangular air outlet appears between the vertical plate 207 and the support plate 201, so that the wind can pass through, thus playing the role of wind resistance. When the wind stops, the first ring 206 on the limit post 204 will return to the normal state under the action of the tensile force of the tension spring 209. At this time, the air outlet between the vertical plate 207 and the support plate 201 will be closed, forming a gap, thereby isolating the lateral transmission of sound again. The vertical plate 207 has two states. One is unfolded to allow the wind to pass through, achieving the effect of wind resistance. The other is closed to isolate the lateral transmission of sound. The first suspension plate 303 and the second suspension plate 304 have two states. When there is no wind force, the first suspension plate 303 and the second suspension plate 304 are vertically installed in the rectangular holes opened on the fixed frame 301, thereby effectively isolating the lateral transmission of sound. When the wind force is large, the first suspension plate 303 and the second suspension plate 304 will be lifted by the wind, thereby exposing the rectangular holes opened on the fixed frame 301, so that the wind can pass through, thus achieving the effect of wind resistance.
