Description

Technical Field

[0001] This utility model relates to the field of high-speed railway road sound barriers, specifically a high-speed railway road sound barrier with an air guiding structure. Background Technology

[0002] A sound barrier is a specially designed acoustic barrier placed between a noise source and a receiving point. It is typically designed for a specific sound source and a specific protected location (or area). Sound barriers are mainly used for noise reduction on highways, expressways, elevated roads, and other noise sources. They are divided into purely sound-insulating reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation; the latter is a more effective sound insulation method. Sound barriers are wall-like structures erected beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound walls are also called noise barriers. A sound barrier is a structure inserted between a sound source and a receiver that significantly attenuates sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. Sound barriers are categorized into traffic noise barriers, equipment noise reduction barriers, and industrial plant boundary noise barriers. Highways and expressways are where all types of sound barriers are most commonly used.

[0003] The strong airflow (300-350km / h) generated by high-speed trains can cause wind pressure to accumulate, increasing the load on the sound barrier and potentially causing resonance or deformation. However, the air-guiding structure can effectively disperse the wind pressure and reduce structural risks. At the same time, optimizing the airflow path can reduce sound wave diffraction and improve noise reduction efficiency. Therefore, a high-speed railway sound barrier with an air-guiding structure is needed. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed railway road sound barrier with a wind-guiding structure to solve the problems mentioned in the background art.

[0006] Preferably, a fastening nut is installed in the middle of the adjusting rod, and the fastening nut is threaded to the adjusting rod. Rotating the fastening nut to press against the upper end of the support rod fixes the length and forms a triangular support.

[0007] Preferably, a support rod is installed at the lower part of the adjusting rod, and the support rod and the adjusting rod are threaded together. The length of the adjusting rod in the support rod is adjusted by adjusting the adjusting nut, thereby changing the overall length of the adjusting rod and the support rod on the rigid base.

[0008] Preferably, a rigid base two is installed at the lower end of the support rod, and the rigid base two is rotatably connected to the support rod.

[0009] Preferably, a sound-absorbing panel is installed on the inner side of the column, and the sound-absorbing panel is embedded in the column. The sound-absorbing panel effectively reduces the decibels of noise and wind noise.

[0010] Preferably, a connecting rod is installed at the front end of the column, and a side frame is installed at the front end of the connecting rod. The connecting rod separates the side frame from the column, leaving a buffer space.

[0011] Preferably, an air guide assembly is installed inside the side frame, and the air guide assembly is rotatably connected to the side frame.

[0012] Preferably, the air guide assembly includes an air guide plate and a return spring, and return springs are installed on both sides of the air guide plate. The air guide plate is appropriately aligned with the airflow direction by the return springs, and then the air guide plate is reset, thereby improving the adaptability and load-bearing capacity of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the column can be adjusted in length by adjusting the extension and retraction of the adjusting rod in the support rod, and after being locked by the fastening nut, it forms a triangular support structure with the rigid base, which enhances the wind load resistance; the air guide plate can achieve adaptive deflection of airflow through the return spring, and the air guide gap formed by the connecting rod can effectively reduce wind pressure, while the sound absorption plate also has a noise reduction function.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] Please see Figures 1-3 This utility model provides a technical solution: A rigid base 1 is installed below the column 1, and the rigid base 1 is embedded in the column 1. An adjusting rod 3 is rotatably connected to the rear end of the adjusting rod 3. An adjusting nut 4 is installed on the upper part of the adjusting rod 3, and the adjusting nut 4 is welded to the adjusting rod 3. A fastening nut 6 is installed in the middle of the adjusting rod 3, and the fastening nut 6 is threaded to the adjusting rod 3. A support rod 5 is installed on the lower part of the adjusting rod 3, and the support rod 5 is threaded to the adjusting rod 3. A rigid base 2 7 is installed at the lower end of the support rod 5, and the rigid base 2 7 is rotatably connected to the support rod 5. The column 1 is embedded in the rigid base 1 2. The length of the adjusting rod 3 in the support rod 5 is adjusted by adjusting the adjusting nut 4, thereby changing the overall length of the adjusting rod 3 and the support rod 5 on the rigid base 2 7. The fastening nut 6 is rotated to press against the upper end of the support rod 5 to fix the length, forming a triangular support, which facilitates the adjustment of the support column 1 and can better withstand the wind load brought by the high-speed rail passing by.

[0022] Example 2

[0023] Based on Embodiment 1, a sound-absorbing panel 8 is installed on the inner side of the column 1, and the sound-absorbing panel 8 is embeddedly connected to the column 1. A connecting rod 9 is installed at the front end of the column 1, and a side frame 10 is installed at the front end of the connecting rod 9. An air guide assembly 11 is installed inside the side frame 10, and the air guide assembly 11 is rotatably connected to the side frame 10. The air guide assembly 11 includes an air guide plate 1101 and a return spring 1102, and return springs 1102 are installed on both sides of the air guide plate 1101. The connecting rod 9 separates the side frame 10 and the column 1. After the wind blows onto the air guide plate 1101, it moves along the gap, reducing the wind pressure and weakening the wind load. The air guide plate 1101 is appropriately aligned with the airflow direction through the return spring 1102, and then the air guide plate 1101 is reset, improving the adaptability and load-bearing capacity of the device and avoiding damage to the rigid structure under large wind pressure. The sound-absorbing panel 8 effectively reduces the decibels of noise and wind noise.

[0024] In actual use, column 1 is stably embedded through rigid base 2. Its core adjustment function is driven by adjusting nut 4. By rotating this nut, the extension and retraction of adjusting rod 3 within support rod 5 can be precisely controlled, thereby changing the effective length of the overall structure at the upper end of rigid base 7. After adjustment, tightening the fastening nut 6 locks the upper end of support rod 5, at which point column 1 and the two rigid bases form a stable triangular support system. The airflow channel reserved between connecting rod 9 and side frame 10 and column 1 creates conditions for the function of air guide plate 1101: when strong winds act on air guide plate 1101, the airflow flows orderly along the gaps in the device, reducing local wind pressure through diversion; the buffer system composed of air guide plate 1101 and return spring 1102 can elastically deflect when subjected to wind pressure, absorbing impact energy and preventing damage to the rigid structure, and automatically resetting after the wind weakens. In addition, the composite acoustic structure of sound-absorbing plate 8 can effectively reduce wheel-rail noise and wind noise generated by high-speed rail operation, achieving a balance between mechanical performance and environmental adaptability of the device.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
