Description

Technical Field

[0001] This invention belongs to the field of vibration reduction and noise reduction technology, specifically, it relates to a noise isolation device for equipment areas. Background Technology

[0002] With the improvement of the national economic level, people's requirements for the comfort of the office environment are also increasing. As an indispensable part of new buildings, air conditioning systems have developed rapidly. At present, the air conditioning systems of large office buildings mainly adopt all-air systems. Each heat load zone is equipped with an air conditioning room. The air conditioning units in the room process the air, and the processed constant temperature and humidity air is transmitted to the surrounding offices through air ducts, thereby creating a comfortable office environment.

[0003] However, the operation of air conditioning systems and other equipment comes at the cost of sacrificing the quality of the surrounding environment. It is well known that while all-air systems provide a comfortable office environment, the vibrations of the air conditioning units and the airflow within the equipment room generate unpleasant noise. This noise not only distracts office workers and reduces work efficiency, but also affects human health, negatively impacting hearing, the nervous system, and the heart. Therefore, controlling noise from office equipment rooms is imperative.

[0004] Conventional soundproof walls mostly use single-layer steel plates or gypsum board structures, relying mainly on the sound insulation performance of the materials themselves, and are poor at isolating low-frequency vibration noise (such as that from motors and transformers). At the same time, sound waves are prone to resonance in a single medium, leading to a decrease in sound insulation.

[0005] Existing technologies typically involve simply stacking vibration damping pads and sound insulation layers, such as a combination of rubber pads and rock wool. However, the vibration damping layer lacks the ability to actively decompose sound waves and relies solely on the material's sound absorption, resulting in limited transmission loss of mid-to-high frequency noise (such as that from fans and pumps).

[0006] Traditional keel frames are fixed by welding or single-sided bolts, which are prone to loosening due to long-term equipment vibration; while panel fixing often uses exposed bolts, which affects the appearance and is prone to dust accumulation. In addition, existing soundproof walls have low modularity, making disassembly and maintenance inconvenient.

[0007] To address the aforementioned issues, this application proposes a noise isolation device for equipment sections. Summary of the Invention

[0008] In view of the problems in related technologies, the present invention proposes a noise isolation device for equipment sections to overcome the above-mentioned technical problems existing in the existing related technologies.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The equipment area noise isolation device includes two aluminum plates. Rubber shock-absorbing pads are installed on the side of the two aluminum plates that are close to each other. Sound insulation cotton is installed between the two rubber shock-absorbing pads. A keel is installed on the side of the two aluminum plates that are far from each other. A panel is installed on the side of the two keels that are far from each other.

[0011] The fixed structure includes multiple fixing connectors that pass through the space between two keels and are connected to the panel.

[0012] Preferably, the keel has multiple mounting holes, bolts pass through the mounting holes, and both ends of the fixing connector have threaded grooves, with the bolts threadedly connected to the corresponding threaded grooves.

[0013] The bolts can be positioned by the mounting holes on the keel, and the two ends of the fixing connector can be fixed between the two keels by the threaded grooves.

[0014] Preferably, the fixing structure further includes multiple bolts, and the panel has countersunk holes in which the bolts are located.

[0015] By using countersunk holes, the ends of the bolts are hidden on the panel, making the panel a completely flat surface.

[0016] Preferably, one end of the countersunk hole has a recessed hole, and a cover plate is fitted and connected inside the recessed hole.

[0017] The recessed holes facilitate the fixing and placement of the cover plate, allowing it to fit perfectly and completely cover the countersunk holes, thus enhancing the aesthetics of the panel.

[0018] Preferably, the rubber shock-absorbing pad has multiple hexagonal grooves on one side, and the multiple hexagonal grooves are arranged adjacent to each other.

[0019] Multiple hexagonal grooves are arranged adjacently to form a honeycomb pattern, which can decompose incoming sound waves, reduce sound wave resonance, and at the same time, the rubber material can increase the shock absorption effect, resulting in better sound insulation.

[0020] In summary, the technical effects and advantages of this invention are as follows:

[0021] Honeycomb acoustic decomposition structure

[0022] Adjacent hexagonal grooves are designed on the rubber damping pad to form a honeycomb layout. This structure achieves efficient sound energy dissipation by decomposing the sound wave path and disrupting the resonance condition, combined with the damping properties of the rubber material.

[0023] Concealed modular fixing system

[0024] The design incorporates countersunk and recessed holes, along with a removable cover plate, to completely conceal the bolts. This maintains a smooth and aesthetically pleasing panel surface while enabling quick maintenance through the cover plate's snap-fit ​​structure.

[0025] Two-way keel stabilizing frame

[0026] A bidirectional tensile structure is formed by the engagement of a fixed connector that runs through both keels and a threaded groove. Bolts are positioned through mounting holes and then tightened bidirectionally to enhance overall rigidity.

[0027] Composite sound insulation layer directional arrangement

[0028] The honeycomb grooves of the two rubber damping pads are aligned in the same direction to form a sound wave phase difference interference layer with the middle sound insulation cotton, which can achieve directional cancellation of noise in specific frequency bands of the equipment (conventional sound insulation layers are mostly randomly stacked and have no synergistic effect).

[0029] Aluminum-rubber gradient impedance design

[0030] The interlayer impedance gradient of aluminum plate, damping pad, and sound insulation cotton gradually attenuates sound waves of different frequencies: aluminum plate reflects high frequencies, honeycomb rubber treats mid frequencies, and sound insulation cotton absorbs low frequencies.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figure 1-4The noise isolation device for the equipment area includes two aluminum plates 1. Rubber shock-absorbing pads 2 are installed on the side of the two aluminum plates 1 that are close to each other. Sound insulation cotton 6 is installed between the two rubber shock-absorbing pads 2. Keel 3 is installed on the side of the two aluminum plates 1 that are far from each other. Panel 4 is installed on the side of the two keels 3 that are far from each other.

[0039] The fixed structure 5 includes multiple fixed connectors 51, which pass through the space between the two keels 3 and are connected to the panel 4.

[0040] Reference Figure 1 and Figure 4 The keel 3 has multiple mounting holes 53, and the bolts 52 pass through the mounting holes 53. Both ends of the fixing connector 51 have threaded grooves 54. The bolts 52 are threadedly connected to the corresponding threaded grooves 54. The bolts 52 can be positioned through the mounting holes 53 on the keel 3, and both ends of the fixing connector 51 can be fixed between the two keels 3 through the threaded grooves 54.

[0041] Reference Figure 4 The fixing structure 5 also includes multiple bolts 52. The panel 4 has countersunk holes 55, and the bolts 52 are located in the countersunk holes 55. By setting the countersunk holes 55, the ends of the bolts 52 are hidden on the panel 4, so that the panel 4 forms a complete plane.

[0042] Reference Figure 4 One end of the countersunk hole 55 has a recessed hole 8, and a cover plate 9 is fitted into the recessed hole 8. The recessed hole 8 makes it easy to fix the cover plate 9 and fit it perfectly, so that the cover plate 9 can completely cover the countersunk hole 55, which is good for the aesthetics of the panel 4.

[0043] Reference Figure 2 The rubber damping pad 2 has multiple hexagonal grooves 7 on one side, and the multiple hexagonal grooves 7 are adjacent to each other, forming a honeycomb structure. This can decompose the incoming sound waves, reduce the resonance of the sound waves, and at the same time, the rubber material can increase the damping effect and form a better sound insulation function.

[0044] Working principle: The two keels 3 provide stable support and fixation for the entire wall. Multiple fixing connectors 51 stabilize the space between the two keels 3. The panel 4 isolates the keel 3 from the aluminum plate 1, increasing the integrity of the wall. Bolts 52 are positioned through the mounting holes 53 on the keels 3, and the two ends of the fixing connectors 51 are fixed between the two keels 3 via threaded grooves 54, thus securing the two keels 3 together. The recessed holes 8 further enhance stability. It is convenient to fix the cover plate 9 in place and fits the cover plate 9 perfectly, so that the cover plate 9 can completely cover the countersunk hole 55, which is good for the aesthetics of the panel 4. Multiple hexagonal grooves 7 are arranged adjacently to form a honeycomb pattern, which can decompose the incoming sound waves and reduce the resonance of the sound waves. At the same time, the rubber material can increase the shock absorption effect and form a better sound insulation function. Meanwhile, the hexagonal grooves 7 on the two rubber shock-absorbing pads 2 are located in the same direction, thereby enhancing the isolation effect in the equipment area. The setting of sound insulation cotton 6 increases the shock absorption and sound insulation effect.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
