Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a high-speed railway sound barrier structure. Background Art

[0002] The sound barrier is mainly composed of a fixed frame and a sound-absorbing panel. It is a specially designed acoustic barrier standing between the noise source and the sound receiving point. It is usually designed for a specific sound source and a specific protection position. The large-scale construction of high-speed railways inevitably brings serious noise pollution problems. The sound barrier is one of the effective ways to solve the noise along the high-speed railway.

[0003] The traditional high-speed railway sound barrier structure is relatively simple, usually using bolts to connect and fix the sound-absorbing panel and the fixing frame. There is a lack of buffer structure. When the train passes through the sound barrier, the huge airflow impact will squeeze the sound-absorbing panel, causing damage to it, reducing the service life and safety of the sound barrier. Therefore, we propose a high-speed railway sound barrier structure. Utility Model Content

[0028] like Figure 1-3As shown, the utility model provides a technical solution: a high-speed railway sound barrier structure, comprising a fixing mechanism 1, a sound insulation board body 2 is symmetrically arranged on the left and right sides of the fixing mechanism 1, the fixing mechanism 1 comprises a fixing column 101, a plurality of fixing columns 101 are arranged according to the sound insulation range, and the distance between two adjacent fixing columns 101 is consistent with the length of the sound insulation board body 2, so as to prevent the sound insulation board body 2 from falling off under the impact of airflow, thereby improving the safety of use, square grooves 102 are symmetrically opened on the left and right sides of the fixing column 101, and slide grooves 103 are symmetrically opened near the front and back sides of the square grooves 102, a first honeycomb sound absorbing board 104 is arranged inside the slide groove 103, a buffer spring 105 is arranged between the slide groove 103 and the first honeycomb sound absorbing board 104, a channel 106 is opened inside the fixing column 101 through the square grooves 102 on the left and right sides, a card slot 107 is opened on the back side of the fixing column 101, and a plurality of second honeycomb sound absorbing boards 108 are equidistantly arranged inside the card slot 107 from front to back. Example

[0029] like Figure 1-3 As shown, the sound insulation board body 2 is adapted to the square groove 102. Through the adaptation of the sound insulation board body 2 and the square groove 102, the sound insulation board body 2 can be easily inserted into the interior of the square groove 102, making the installation more convenient. The first honeycomb sound absorbing board 104 is slidably connected with the slide groove 103. Through the sliding connection between the first honeycomb sound absorbing board 104 and the slide groove 103, the first honeycomb sound absorbing board 104 can move with the movement of the sound insulation board body 2 to improve the sound absorption effect. The two ends of the buffer spring 105 are respectively fixedly connected with the slide groove 103 and the first honeycomb sound absorbing board 104. Through the fixed connection of the buffer spring 105 with the slide groove 103 and the first honeycomb sound absorbing board 104, the first honeycomb sound absorbing board 104 and the sound insulation board The main body 2 fits more closely, which improves the overall stability of the device. The square groove 102, the channel 106 and the card slot 107 are connected. After the airflow passes through the obstruction of the sound insulation board main body 2, part of it enters the inside of the square groove 102, and then the noise mixed in the airflow is adsorbed by the first honeycomb sound-absorbing panel 104. The airflow enters the inside of the channel 106, and finally the noise is further eliminated by the second honeycomb sound-absorbing panel 108. After that, it is discharged from the card slot 107, reducing the pressure of the airflow on the sound insulation board main body 2 and improving the service life. The second honeycomb sound-absorbing panel 108 is adapted to the card slot 107, and the adaptation of the second honeycomb sound-absorbing panel 108 to the card slot 107 can make the two more compatible and improve the sound absorption effect.

[0030] The working process of the utility model is as follows: when a high-speed railway sound barrier structure is used for sound insulation, first, when a train passes through, it drives the airflow to squeeze the front side of the sound insulation board body 2, and the noise in the airflow can be blocked by the sound insulation board body 2 to prevent it from affecting the external environment. At the same time, under the push of the airflow, the sound insulation board body 2 moves to the back side inside the square groove 102 through the buffer spring 105 to prevent the airflow from causing damage to it, thereby improving the service life and safety of use. Under the action of the buffer spring 105 close to the front side of the square groove 102, the first bee The nested sound-absorbing panel 104 is pushed toward the back inside the slide groove 103, so that its back side is closely fitted with the front side of the sound-insulating panel body 2. At the same time, part of the airflow enters the inside of the square groove 102, and the noise mixed inside can be initially eliminated through the first honeycomb sound-absorbing panel 104. Then the airflow enters the inside of the channel 106 and enters the card groove 107, and then passes through the second honeycomb sound-absorbing panel 108 to eliminate the noise for a second time. Finally, the eliminated airflow is discharged from the back side of the fixed column 101, completing the entire sound insulation process. The discharged airflow can be subjected to multiple sound absorption and noise reduction, thereby improving the sound insulation effect.
