Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation screens, in particular to a highway sound insulation screen with a protective structure. Background Art

[0002] A sound barrier 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 location (or area). Sound barriers are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method.

[0003] A Chinese patent with authorization announcement number CN216474605U discloses a highway soundproof screen with a protective structure, which uses a mounting seat to quickly install the clip-on columns at equal intervals on the top of the base, and assembles the first soundproof board and the transparent plate between two adjacent clip-on columns, making the installation and disassembly of the soundproof assembly more convenient. Then, a protective cover is covered on the top between the two clip-on columns to facilitate rain protection of the soundproof screen below. When the anti-collision plate is hit, the anti-collision plate pushes and squeezes the elastic buffer, and uses the rebound of the elastic buffer to weaken the impact force generated by the vehicle hitting the anti-collision plate, thereby preventing the soundproof screen from being damaged.

[0004] Although the above solution protects the sound insulation component by means of the anti-collision plate at the bottom of the sound insulation component, the protection area of ​​the anti-collision plate on the sound insulation component is limited, and there are unprotected blind areas on the sound insulation component, which results in poor protection effect on the sound insulation component. To this end, we provide a highway sound insulation screen with a protective structure to solve the above problems. Utility Model Content

[0005] 1) Technical issues solved

[0006] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a highway soundproof screen with a protective structure.

[0007] 2) Technical solution

[0008] To achieve the above purpose, the utility model provides the following technical solution: a highway soundproof screen with a protective structure, comprising:

[0009] The sound insulation component comprises a concrete pile, on which vertical poles arranged at equal intervals are installed, and sound insulation boards are arranged between adjacent vertical poles.

[0010] The protection assembly comprises a second protection plate and two first protection plates, wherein the two first protection plates respectively cover the upper part and the lower part of the second protection plate.

[0011] The elastic support assembly is installed on the vertical pole and is used to buffer the impact force on the first protective plate and the second protective plate.

[0012] Furthermore, both side surfaces of the vertical pole are provided with installation grooves, and the two ends of the sound insulation board are respectively inserted into the two installation grooves.

[0013] Furthermore, a limiting slot plate is arranged above the concrete pile, and fixing bolts are installed on the limiting slot plate, and the bottom end of the fixing bolt is threadedly connected to the vertical pole.

[0014] Furthermore, the elastic support assembly includes a storage box installed on the vertical pole, the storage box is provided with a guide groove, a linkage rod is slidably connected in the guide groove, and two linkage rods are respectively installed on the first protective plate and the second protective plate.

[0015] Furthermore, a control groove is provided on the linkage rod, and a guide rod is slidably connected to the linkage rod. One end of the guide rod is fixedly connected to the storage box, and the other end of the guide rod is fixedly connected to a fixing plate, and the fixing plate is located in the control groove.

[0016] Furthermore, a buffer spring is sleeved on the guide rod, and the buffer spring is located outside the linkage rod, and a damping block is fixedly connected to the inner wall of the control groove.

[0017] 3) Beneficial effects:

[0018] Compared with the prior art, the highway noise barrier with a protective structure has the following beneficial effects:

[0019] 1. The utility model not only provides comprehensive protection for the sound insulation component through the coordinated use of the second protective plate of the protective component and the two first protective plates, avoiding the possible blind spots in the traditional design, but also forms an additional sound insulation enclosure, thereby significantly improving the overall sound insulation effect of the sound insulation screen. This means that even in a complex and changeable road environment, the sound insulation screen can effectively reduce noise pollution and provide better acoustic protection for the surrounding environment.

[0020] 2. The utility model provides an effective impact force buffering mechanism for the protection component by setting an elastic support component and utilizing the combination of a linkage rod and a buffer spring. When the anti-collision plate is hit by a vehicle, the linkage rod telescopes in the guide groove, and the buffer spring absorbs and disperses the impact force. At the same time, the contact between the fixed plate and the damping block further enhances the damping effect of the impact force, which not only reduces the impact force directly acting on the sound insulation screen, but also ensures the stability and durability of the sound insulation screen structure, thereby extending its service life.
