Description

Technical Field

[0001] The utility model relates to a modular combined sound insulation barrier, belonging to the field of sound insulation barriers. Background Art

[0002] With the acceleration of the urbanization process, the problem of traffic noise pollution has become increasingly serious, having a certain impact on the quality of residents' lives and the urban environment. Therefore, as an effective means of noise control, sound insulation barriers have received extensive attention and applications.

[0003] Traditional sound insulation barriers usually adopt a fixed design. Once installed, it is difficult to adjust their height and shape, which brings many inconveniences in practical applications. Due to the non-adjustability of height and shape, traditional sound insulation barriers often cannot adapt to different terrains and the heights of noise sources. In complex terrain areas such as mountains and hills, it is often difficult to find a suitable installation position for fixed sound insulation barriers, resulting in unsatisfactory sound insulation effects. At the same time, with the continuous development of urban construction, the height of noise sources may also change, such as newly built high-rise buildings. Fixed sound insulation barriers cannot adjust their heights accordingly, thus affecting their sound insulation effects. Content of the Utility Model

[0025] See also Figures 1-4 A modular combined sound barrier comprises a frame 1, a mounting frame 2 and a sound barrier body 3. An adjusting structure for adjusting the height of the sound barrier body 3 is provided on the inner side of the frame 1.

[0026] Embodiment 1, as Figure 1 As shown, the adjustment structure includes a partition 4 fixedly connected to the inner bottom wall of the frame 1, a threaded rod 5 rotatably connected to the left and right sides of the partition 4, a threaded block 6 threadedly connected to the outer side of the threaded rod 5, a connecting block 7 fixedly connected to the upper surface of the threaded block 6, a first hinge seat 8 fixedly connected to the upper surface of the connecting block 7, a connecting strip 9 hinged to the inner side of the first hinge seat 8, a second hinge seat 10 hinged to the other end of the connecting strip 9, a slider 11 fixedly connected to the upper surface of the second hinge seat 10, and a sliding rod 12 slidably connected to the inner side of the slider 11;

[0027] Both left and right sides of the mounting frame 2 are provided with connection components for facilitating the disassembly and assembly of the sound insulation barrier body 3 .

[0028] It should be noted that the left threaded rod 5 is located behind the right threaded rod 5. The two connecting bars 9 are distributed in an "X" shape. The left end of the left threaded rod 5 penetrates the inner left side wall of the frame body 1 and extends to the outside of the frame body 1. And the right end of the right threaded rod 5 penetrates the inner right side wall of the frame body 1 and extends to the outside of the frame body 1. And one end of the threaded rod 5 extending to the outside of the frame body 1 is fixedly connected with a torsion cap. The upper surface of the partition plate 4 is fixedly connected with a limiting plate 13. And a chute adapted to the connecting block 7 is provided on the upper surface of the limiting plate 13. The left and right ends of the sliding rod 12 are bent upward and fixedly connected with the bottom of the mounting frame 2. The sound insulation barrier body 3 is jointly composed of a mineral wool board 301, a sound insulation felt 302 and a polyester fiber sound absorption board 303. The mineral wool board 301 is made of mineral fibers, has good sound absorption performance, can effectively reduce the transmission of sound. In addition, it also has heat preservation and fire prevention properties and is suitable for various environments. The sound insulation felt 302 is made of materials such as rubber and polyester fiber, has good sound insulation effect and heat insulation performance, and further improves the sound insulation performance. The polyester fiber sound absorption board 303 has the characteristics of sound insulation, and has good stability and good impact resistance.

[0029] The connecting assembly includes brackets 14 respectively fixedly connected to the left side and the right side of the mounting frame 2, elastic telescopic rods 15 fixedly connected to the inner sides of the brackets 14, fixing rods 16 fixedly connected to the piston rods of the elastic telescopic rods 15, and positioning cylinders 17 sleeved on the other ends of the fixing rods 16. The two positioning cylinders 17 are respectively fixedly connected to the left side of the upper surface of the sound insulation barrier body 3 and the right side of the upper surface, and the sound insulation barrier body 3 is located inside the mounting frame 2.

[0030] Embodiment 2, on the basis of Embodiment 1, for the material constituting the sound insulation barrier body 3, in addition to using the sound insulation felt 302, glass wool can also be used. Glass wool is a sound insulation material made of glass fibers, has a porous structure, can effectively absorb sound waves, thereby reducing noise transmission.

[0031] The working principle of the above embodiments is as follows:

[0032] By rotating the torsion cap to drive the threaded rod 5 to rotate, the threaded rod 5 then drives the threaded block 6 to move, the threaded block 6 then drives the connecting block 7 to move, and the connecting block 7 then drives the first hinge seat 8 to move. At this time, the first hinge seats 8 on the left and right sides move in opposite directions. During this process, when the first hinge seat 8 moves, the pulling force it generates on the connecting bar 9 will cause the connecting bar 9 to rotate at the hinge point. This rotation causes the intersection point of the connecting bar 9 to rise. And since the other end of the connecting bar 9 is hinged to the second hinge seat 10, therefore, the rise of the intersection point will push the second hinge seat 10 to rise, thereby realizing the lifting of the mounting frame 2, and thus adjusting the height of the sound insulation barrier body 3 inside the mounting frame 2;

[0033] When it is necessary to replace the sound insulation barrier body 3, by pressing the elastic telescopic rod 15, the elastic telescopic rod 15 drives the fixing rod 16 to be pulled out from the positioning cylinder 17, thereby releasing the connection between the sound insulation barrier body 3 and the mounting frame 2, and then pulling out the sound insulation barrier body 3 from the inner side of the mounting frame 2 to achieve convenient replacement of the sound insulation barrier body 3.

[0034] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
