[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an embodiment of the present invention provides a noise absorption baffle, comprising: a frame 1; two sound insulation components 2, one of which is fixedly installed on the inner wall of the frame 1, and the other sound insulation component 2 is placed inside the frame 1, with a gap between the two sound insulation components 2; a positioning component 3 is installed on the frame 1 for positioning and fixing the other sound insulation component 2; the positioning component 3 includes four rotating plates 31 respectively rotatably installed at the four opposite corners of the frame 1, each of the four rotating plates 31 having a screw 32 threadedly installed on it, and a circular plate 33 fixedly installed at one end of each screw 32.

[0022] The sound insulation component 2 includes an aluminum alloy frame 21, a substrate 22, double-glazed glass 23, sound-absorbing cotton 24, and a sound insulation board 25. The aluminum alloy frame 21 is installed on the inner periphery of the frame 1, the substrate 22 is fixedly installed on the inner periphery of the aluminum alloy frame 21, the double-glazed glass 23 is fixedly installed on one side of the substrate 22, the sound-absorbing cotton 24 is fixedly installed on one side of the double-glazed glass 23, and the sound insulation board 25 is fixedly installed on one side of the sound-absorbing cotton 24. The substrate 22 includes a bamboo fiberboard 221, and a honeycomb-structured sound-absorbing layer 222 is provided on both sides of the bamboo fiberboard 221. The sound-absorbing layer 222 is made of modified melamine foam material, and the honeycomb pores of the sound-absorbing layer 222 are filled with sound-absorbing particles, which are a mixture of ceramsite and vermiculite.

[0023] Bamboo fiberboard 221 has good strength and environmental performance. The sound-absorbing layer 222 made of modified melamine foam material adopts a honeycomb structure, which can effectively increase the reflection and friction path of sound waves and improve the sound absorption effect. The filling of sound-absorbing particles further enhances the sound absorption capacity. The mixture of ceramsite and vermiculite can absorb sound waves in different frequency ranges. The two work together to improve the overall sound absorption performance.

[0024] The aluminum alloy frame 21 on the fixed sound insulation component 2 is fixed to the frame 1, and the outer periphery of the aluminum alloy frame 21 on the sound insulation component 2 placed inside the frame 1 is attached to the inner periphery of the frame 1, so that the other sound insulation component 2 can be moved. According to the noise environment requirements, the sound insulation material inside the frame 1 and located in the two sound insulation components 2 can be increased or decreased.

[0025] First, the partition consists of a frame 1 forming the basic framework. One sound insulation component 2 is fixedly installed on its inner wall, while another sound insulation component 2 is placed inside the frame 1, with a gap between them. This design allows the other sound insulation component 2 to be removed after the positioning component 3 has released its fixation. Sound insulation material can then be added to the frame 1, or the sound insulation material can be removed and used for other purposes when not needed. The positioning component 3 ensures that the other sound insulation component 2 inside the frame 1 remains in the correct position, preventing displacement due to external forces or vibrations, thus maintaining the sound insulation performance of the partition. Simultaneously, the positioning component 3 also ensures the stability of the proximity between the two sound insulation components 2. The sound insulation component 2 consists of an aluminum alloy frame 21, a substrate 22, double-glazed glass 23, sound-absorbing cotton 24, and a sound insulation panel 25. The aluminum alloy frame 21 is installed on the inner periphery of the frame 1, providing good structural support and protection for the sound insulation component 2, making it less prone to damage during installation and use. The substrate 22 is fixed to the inner periphery of the aluminum alloy frame 21, the double-glazed glass 23 is fixed to one side of the substrate 22, the sound-absorbing cotton 24 is fixed to one side of the double-glazed glass 23, and the sound insulation panel 25 is fixed to one side of the sound-absorbing cotton 24. This structural design allows noise waves to be absorbed effectively. Upon reaching the partition, the sound waves are transmitted through the substrate 22 to the double-glazed glass 23. The gap between the double-glazed glass 23 and the sound-absorbing cotton 24 further absorb and weaken the energy of the sound waves. Finally, the soundproofing panel 25 acts as the last line of defense, effectively blocking the propagation of any remaining sound waves. This multi-layered structure not only improves the sound insulation effect of the partition but also allows for adaptation to different noise levels due to the detachable and reconfigurable nature of the two soundproofing components 2. This allows for flexible addition or reduction of soundproofing materials to achieve optimal sound insulation while minimizing waste. Through this setup, the partition can provide effective sound insulation solutions in various noise environments while maintaining structural flexibility and sustainability.

[0026] like Figure 3 As shown, in some embodiments, the positioning component 3 includes four rotating plates 31 respectively rotatably mounted at the four opposite corners of the frame 1, and each of the four rotating plates 31 is threaded with a screw 32, and a circular plate 33 is fixedly mounted at one end of the screw 32.

[0027] The rotating plate 31 rotates at the diagonal of the frame 1 via the damping shaft, rotating the rotating plate 31 to the front of the sound insulation component 2. Then, the rotating screw 32 drives the circular plate 33 to approach the other sound insulation component 2, pushing it to move closer to the fixed sound insulation component 2, thereby squeezing and fixing the sound insulation material added between the two sound insulation components 2, so that there is no gap between them.

[0028] like Figure 3 As shown, in some embodiments, a sealing gasket 4 is fixedly installed on one side of the aluminum alloy frame 21, and the outer periphery of the sealing gasket 4 is tightly fitted to the inner periphery of the frame 1. The sealing gasket 4 is located on one side of the movable aluminum alloy frame 21.

[0029] The sealing gasket 4 can effectively prevent sound from leaking from any gaps that may exist between the aluminum alloy frame 21 and the frame 1, further improving the overall sound insulation effect of the device.

[0030] like Figure 2 As shown, in some embodiments, the substrate 22 is provided with a plurality of semi-circular arc-shaped holes 5, which are arranged in an array.

[0031] When the noise wave impacts the substrate 22, part of the sound wave is dispersed and enters multiple semi-circular arc holes 5 for dispersion, and then scatters out of the semi-circular arc holes 5, thus blocking and dispersing the noise, thereby improving the sound insulation effect.

[0032] like Figure 4 As shown, in some embodiments, a sound-absorbing layer 222 is provided on one side with a sound-insulating membrane layer 6. The sound-insulating membrane layer 6 is a polycarbonate film with a thickness of 0.2-0.5 mm and micropores with a diameter of 0.1-0.3 mm are uniformly distributed on the sound-insulating membrane layer 6.

[0033] Polycarbonate films themselves have certain sound insulation properties, and their microporous structure can further scatter and absorb sound waves.

[0034] like Figure 2 As shown, in some embodiments, the double-layered glass 23 is provided with an inner groove filled with an inert gas.

[0035] Inert gases are denser than air, which effectively reduces sound wave propagation, lowers noise, and improves the sound insulation performance of double-glazed windows.

[0036] like Figure 4 As shown, in some embodiments, the bamboo fiberboard 221 is provided with a plurality of longitudinal reinforcing ribs 7, the longitudinal reinforcing ribs 7 being carbon fiber rods, and the diameter of the longitudinal reinforcing ribs 7 being 2-4 mm.

[0037] Carbon fiber rods can significantly enhance the strength and rigidity of bamboo fiberboard 221, enabling the partition to withstand greater external forces without deformation, ensuring its normal use in various complex environments and extending its service life.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
