Example

[0027] Please see Figures 1-4 In this embodiment of the present invention, a modular noise-reducing armor includes a first outer protective layer 1. The first outer protective layer 1 has a first outer sound insulation layer 2 and a sound absorption layer 3 disposed inside it. The sound absorption layer 3 is disposed at the lower end of the first outer sound insulation layer 2. The first outer protective layer 1 wraps around the sidewalls of the first outer sound insulation layer 2 and the sound absorption layer 3. The first outer protective layer 1 is provided with a first connecting mechanism for splicing two noise-reducing armors together.

[0028] To meet higher sound insulation requirements, an inner sound insulation layer 4 is provided at the end of the sound-absorbing layer 3 away from the first outer sound insulation layer 2, and an elastic anti-coupling layer 5 is provided at the end of the inner sound insulation layer 4 away from the sound-absorbing layer 3. The first outer protective layer 1 wraps around the sidewalls of the first outer sound insulation layer 2, the sound-absorbing layer 3, the inner sound insulation layer 4, and the elastic anti-coupling layer 5. The sound-absorbing layer 3, the inner sound insulation layer 4, and the elastic anti-coupling layer 5 have the same length.

[0029] The first connecting mechanism includes a first hook and loop fastener surface 6. The length of the first outer sound insulation layer 2 is greater than the length of the sound absorption layer 3. One end of the first outer sound insulation layer 2 is flush with one end of the sound absorption layer 3. The first hook and loop fastener surface 6 is installed on the side of the upper end of the first outer protective layer 1 that is close to the flush end face of the first outer sound insulation layer 2 and the sound absorption layer 3. The first hook and loop fastener hook surface 7 is installed on the lower end of the first outer protective layer 1 that extends a certain distance beyond the sound absorption layer 3.

[0030] In use, the first hook side 7 of one noise-reducing armor is attached to the first hook side 6 of the other noise-reducing armor, thus splicing the two noise-reducing armors together. Then, the spliced ​​noise-reducing armor is wrapped and fixed on the device.

[0031] The first outer protective layer 1 is made of textile material with good weather resistance, fire retardancy, waterproof and sun protection, corrosion resistance and wear resistance.

[0032] The elastic anti-coupling layer 5 is made of one of the following: flexible ultrafine sound-absorbing material, open-cell foamed rubber and plastic, silicone material, or closed-cell foamed rubber and plastic. This gives the elastic anti-coupling layer 5 good elastic anti-coupling performance, good sound absorption performance, good fire resistance and flame retardancy performance, no corrosive substances leaching, and long service life.

[0033] The first outer sound insulation layer 2 and the inner sound insulation layer 4 are made of either a flexible sound insulation material or a metal sheet material that allows for sufficient deformation, so that the first outer sound insulation layer 2 and the inner sound insulation layer 4 have good sound insulation performance, fire-retardant performance, no corrosive substances are released, and a long service life. Example

[0034] Please see Figures 5-9 The difference between this embodiment and embodiment 1 is that the first connecting mechanism is replaced by the second connecting mechanism. The second connecting mechanism includes a sealing strip. The first outer sound insulation layer 2 has the same length as the sound absorption layer 3, the inner sound insulation layer 4, and the elastic anti-coupling layer 5. The upper two ends of the first outer protective layer 1 are each equipped with a second hook and loop fastener 8.

[0035] The sealing strip includes a second outer sound insulation layer 10, and a second outer protective layer 9 is wrapped on the side wall of the second outer sound insulation layer 10. A second hook and loop fastener hook surface 11 is installed at the lower end of the second outer protective layer 9. The length of the second hook and loop fastener hook surface 11 is the same as the length of the two second hook and loop fastener rough surfaces 8 spliced ​​together.

[0036] When in use, align the edges of the two noise-reducing armors together, then stick the second hook side 11 of the sealing strip to the two aligned second hook side 8. The gap between the two spliced ​​noise-reducing armors is sealed and noise is reduced by the second outer sound insulation layer 10 inside the sealing strip. Then, the spliced ​​noise-reducing armor is wrapped and fixed on the equipment.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
