In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] Please refer to the following: Figures 1 to 8 The windproof sound barrier provided in this application will now be described. The windproof sound barrier includes a soundproof panel 1 for fixing along the railway line. Multiple sets of windproof components are provided on the sides of the soundproof panel 1 facing and away from the railway, and each set of windproof components includes a bracket 2, a wind guide plate 3, and an adjustment component 4.

[0049] The sound insulation panel 1 can be made of materials such as polyurethane foam, high-density glass wool, and 5A03 aluminum plate. These materials have good compressibility and impact resistance, and can significantly improve the sound insulation and noise reduction effect of the sound barrier, while reducing weight and facilitating installation and maintenance. The sound insulation panel 1 has multiple evenly arranged sound-absorbing holes on the side facing and / or away from the railway. The sound-absorbing holes allow sound waves to be reflected and absorbed multiple times when they hit the sound insulation panel 1, thereby improving the sound insulation effect.

[0050] The bracket 2 is fixedly installed on the side of the soundproof panel 1 facing or away from the railway direction. The bracket 2 can be installed on the soundproof panel 1 by welding.

[0051] The air guide plate 3 is hinged to the bracket 2, and the hinge axis is parallel to the surface of the sound insulation plate 1.

[0052] The adjusting component 4 is disposed between the bracket 2 and the air guide plate 3, and is connected to the bracket 2 and the air guide plate 3 to adjust and fix the angle between the air guide plate 3 and the surface of the sound insulation plate 1.

[0053] In this embodiment, the soundproof panel 1 is fixedly installed along the railway line, and multiple sets of windproof components are set on the side of the soundproof panel 1 facing or away from the railway. The bracket 2 in each set of windproof components is fixedly set on the soundproof panel 1, and the wind guide plate 3 is hinged to the bracket 2, with the hinge axis parallel to the surface of the soundproof panel 1. In windy weather, after the airflow blows onto the surface of the wind guide plate 3, part of the force generated by the airflow will be converted into a downward force pushing the wind guide plate 3, thereby weakening the direct blowing force of the airflow and strengthening the stability of the soundproof panel 1. By controlling the adjusting component 4 set between the bracket 2 and the wind guide plate 3, the angle between the wind guide plate 3 and the surface of the soundproof panel 1 is adjusted, thereby changing the windward angle of the wind guide plate 3 to improve the applicability of the windproof sound barrier.

[0054] The windproof sound insulation barrier provided by the embodiments of the present application has strong stability and remarkable windproof effect, and can cope with the influence of various strong convection weather.

[0055] In some embodiments, the wind deflector 3 can adopt the structure as shown in Figure 1 、 Figure 2 and Figure 5 , and as shown in Figure 1 、 Figure 2 and Figure 5 , the wind deflector 3 has a plurality of bosses 31 arranged at intervals along the hinge axis on one side or both sides of the thickness direction of the wind deflector 3.

[0056] By adopting the above technical solution, when the airflow in the strong wind weather blows on the wind deflector 3, the plurality of bosses 31 can guide the airflow blown from different directions to flow along the extension direction of the boss 31, thereby improving the airflow guiding effect of the wind deflector 3 and avoiding the influence of the airflow from other directions on the sound insulation board 1.

[0057] In some embodiments, the adjusting member 4 can adopt the structure as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , and as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the adjusting member 4 includes a first connecting rod 41, a second connecting rod 42 and an adjusting sleeve 43.

[0058] The first connecting rod 41 is hinged on the bracket 2, and the swinging end has a first threaded portion.

[0059] The second connecting rod 42 is hinged on the wind deflector 3, and the swinging end has a second threaded portion.

[0060] The adjusting sleeve 43 is arranged between the bracket 2 and the wind deflector 3, and the two ends of the adjusting sleeve 43 are respectively threadedly connected with the first threaded portion and the second threaded portion; wherein the adjusting sleeve 43 has two internal threaded portions inside, and the two internal threaded portions are respectively threadedly connected with the first threaded portion and the second threaded portion.

[0061] The screw thread directions of the first threaded portion and the second threaded portion are opposite.

[0062] The railway worker can make the first connecting rod 41 and the second connecting rod 42 move towards or away from each other by rotating the adjusting sleeve 43, so as to reduce or increase the included angle between the wind deflector 3 and the surface of the sound insulation board 1, thereby conveniently adjusting the wind-approaching angle of the wind deflector 3.

[0063] In some embodiments, the sound insulation board 1 can adopt the structure as shown in Figure 1 、 Figure 2and Figure 5 As shown in the structure, refer to Figure 1 , Figure 2 and Figure 5 The sound insulation board 1 has a plurality of mounting holes 11 penetrating in the up-down direction, and the sound insulation board 1 further comprises a base 7.

[0064] The base 7 is used to be fixed on the ground along the railway, and the base 7 has a plurality of columns 71 which are adapted to be inserted into the mounting holes 11 one by one.

[0065] The plurality of columns 71 are inserted into the sound insulation board 1, which can enhance the overall strength of the sound insulation board 1, improve the structural strength of the sound insulation board 1, and improve the ability of the sound insulation board 1 to deal with strong convection weather such as strong wind.

[0066] In some embodiments, the above-mentioned sound insulation barrier can adopt the structure as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The windproof sound insulation barrier further comprises a plurality of elastic members 5.

[0067] The plurality of elastic members 5 are respectively arranged on the plurality of columns 71, and are all connected with the sound insulation board 1 to limit the upward movement of the sound insulation board 1 relative to the base 7.

[0068] Because the ground on both sides of the railway will be subjected to strong vibration when the train passes, by using the above technical solution, the plurality of elastic members 5 can reduce the influence of vibration on the sound insulation board 1, and avoid that the strong vibration causes the fasteners on the sound insulation board 1 to loosen; at the same time, the elastic members 5 can also buffer the vibration caused by the airflow blowing on the deflector 3 in strong wind weather, thereby improving the overall stability of the sound insulation barrier.

[0069] In some embodiments, the above-mentioned elastic member 5 can adopt the structure as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The elastic member 5 comprises a first spring 51 and a second spring 52.

[0070] The first spring 51 is sleeved on the column 71, and the two ends of the first spring 51 are respectively connected with the sound insulation board 1 and the base 7.

[0071] The second spring 52 is sleeved on the stand 71, and one end of the second spring 52 is connected with the sound insulation board 1, and the other end is connected with the upper end of the stand 71 through the limiting structure 6.

[0072] When the base 7 is connected with the sound insulation board 1, the first spring 51 is in a free state or an elastic tension state, and the second spring 52 is in a free state or an elastic compression state; when the base 7 is moved upward to be separated from the sound insulation board 1, the first spring 51 is in an elastic tension state, and the second spring 52 is in an elastic compression state.

[0073] The cooperation of the first spring 51 and the second spring 52 can reduce the damage of vibration to the upper and lower ends of the sound insulation board 1, and avoid the loosening of the connecting member on the sound insulation board 1 caused by strong vibration; at the same time, the cooperation of the first spring 51 and the second spring 52 can also buffer the vibration caused by the airflow blowing on the deflector 3 in strong wind weather, thereby improving the stability of the whole sound insulation barrier.

[0074] In some embodiments, the limiting structure 6 described above can adopt the structure as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , and as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the stand 71 has an external thread structure extending to the upper end thereof, and the limiting structure 6 comprises a check ring 61 and a limiting nut 62.

[0075] The check ring 61 is sleeved on the stand 71, and the lower end surface of the check ring 61 is connected with the second spring 52.

[0076] The limiting nut 62 is threadedly connected on the stand 71 and is located on the upper side of the check ring 61, so that the lower end surface of the limiting nut 62 abuts against the upper end surface of the check ring 61.

[0077] By rotating the limiting nut 62, the limiting nut 62 can be moved along the axial direction of the stand 71, and at the same time, the second spring 52 is adapted to be elongated or shortened, and the check ring 61 is pushed to move along the axial direction of the stand 71; when the sound insulation board 1 is installed, the worker can push the check ring 61 to move towards the sound insulation board 1 by rotating the limiting nut 62, so as to push the second spring 52 to be compressed and deformed, and this installation process saves time and labor.

[0078] In some embodiments, the stand 71 described above can adopt the structure as shown in Figure 1 , and as shown in Figure 2 , the stand 71 has a through hole 711 penetrating in the radial direction; the through hole 711 is located on the upper side of the limiting nut 62, and a pin shaft 73 for abutting against the limiting nut 62 is inserted in the through hole 711.

[0079] By adopting the technical scheme, the limiting nut 62 is at risk of moving upward along the axis direction of the stand column 71 until falling off due to vibration after long-time use, the pin shaft 73 can limit the maximum distance of upward movement of the limiting nut 62, thereby ensuring that the limiting nut 62 will not fall off after long-time use, and improving the overall service life of the sound insulation barrier.

[0080] In some embodiments, the base 7 can adopt the structure as shown in Figure 4 , Figure 5 , Figure 6 and Figure 1 . Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 , the base 7 has a groove 72 for embedding the sound insulation board 1, and each stand column 71 is fixedly arranged at the groove bottom of the groove 72.

[0081] The groove 72 on the base 7 can block airflow from passing through the gap between the sound insulation board 1 and the base 7, thereby avoiding the airflow from lifting the sound insulation board 1 from the bottom of the sound insulation board 1, and improving the stability of the sound insulation board 1.

[0082] In some embodiments, the sound insulation board 1 can adopt the structure as shown in Figure 1 , Figure 2 , Figure 5 and Figure 7 . Referring to Figure 1 , Figure 2 , Figure 5 and Figure 7 , the surface of the sound insulation board 1 adopts an inwardly recessed arc surface 12.

[0083] The arc surface 12 is designed to enable sound waves to be reflected and absorbed multiple times when hitting the sound insulation board 1, thereby improving the sound insulation effect of the sound insulation board 1; this design can significantly improve the sound insulation effect of the sound insulation board 1, achieving higher sound insulation standards; in addition, the arc surface 12 design enables airflow to change the flow direction when blowing onto the sound insulation board 1, thereby reducing the direct force on the sound insulation board 1, so that the sound insulation board 1 is not easily blown away or blown up; when air flows through the arc surface 12, the flow rate is fast, resulting in low pressure; while in the flat part, the air flow rate is slow, and the pressure is high. This pressure difference makes the place with high pressure move to the place with low pressure, thereby giving the sound insulation board 1 a downward force, enhancing its stability.

[0084] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
