Description

Technical Field

[0001] The utility model relates to the field of sound-absorbing covers, and more particularly to a fire-proof and noise-reducing elastic sound-absorbing cover. Background Art

[0002] A sound-absorbing enclosure is a device used to reduce noise, typically made of sound-absorbing materials. It's typically designed in a hood shape, which leverages the principles of sound wave reflection and scattering to cause sound waves to continuously reflect, overlap, and cancel each other outward within the enclosure, thereby reducing outward sound energy and extending the sound wave's propagation path within the enclosure, increasing sound energy attenuation.

[0003] However, the existing elastic sound-absorbing covers do not have fireproof properties. Once a fire occurs, the non-fireproof sound-absorbing covers are extremely easy to burn, which will accelerate the spread of the fire and quickly expand the fire to a larger area, causing serious damage to surrounding equipment and facilities. At the same time, the sound-absorbing material in the sound-absorbing cover will also produce harmful gases when it burns, affecting the health of surrounding workers. Secondly, the existing sound-absorbing covers are usually made of hard materials, which makes them extremely easy to be blocked during the installation process and difficult to use in narrow environments. At the same time, when the hard materials are connected, there will be a large gap in the middle, and noise will escape from the gap, thereby affecting the sound insulation effect.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a fire-proof grade noise reduction elastic sound-absorbing cover. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a fire-proof grade noise reduction elastic sound-absorbing cover.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fire-proof grade noise-reducing elastic sound-absorbing cover, comprising a fireproof layer A, a sound insulation layer and a fireproof layer B;

[0007] The fireproof layer A and the fireproof layer B are both made of fire-proof grade noise-reducing thermoplastic elastomer composite materials. The fireproof layer A is in the shape of a hood, and the fireproof layer B is arranged at its opening, and its elasticity is used to contact with the sound-emitting part for sealing. The sound insulation layer is made of a flexible sound insulation material and is arranged on the inner surface of the fireproof layer A. The outer surface of the fireproof layer A is provided with a mounting structure near the opening.

[0008] Preferably, the sound insulation layer is sound insulation cotton, sound insulation felt or polyurethane foam.

[0009] Preferably, the mounting structure includes a circular groove seat fixed on the outer wall of the fireproof layer A near the opening, and a fixed circular ring fixed on the sound output part of the equipment. After the circular groove seat is inserted into the fixed circular ring, the raised part on the circular groove seat is inserted into the recessed part of the circular groove seat, and finally the two are fixed.

[0010] Preferably, the upper and lower sides of the circular groove seat are interconnected with expansion groove seats, both sides of the inner top wall of the expansion groove seat are fixed to the fixed block by springs, the upper and lower sides of the fixed ring are provided with grooves for inserting the fixed block, and the front and rear sides of the expansion groove seat are open.

[0011] Preferably, a transverse plate is fixedly connected to the back of the fixing block near the top, and a handle is welded to the top of the transverse plate for facilitating lifting the fixing block. During installation, the staff is required to pull the fixing block by the handle.

[0012] Preferably, the opposite surfaces of the fixing block and the fixing ring are both provided with beveled edges.

[0013] Preferably, a telescopic rod is fixedly connected to the middle portion between the top end of the fixed block and the inner top wall of the expansion slot seat to maintain the vertical linear movement of the fixed block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, since both the fireproof layer A and the fireproof layer B are made of a fire-rated noise-reducing thermoplastic elastomer composite material, the fireproof layer B and the fireproof layer A both have a certain elasticity. The fireproof layer B utilizes its elasticity to cling to the sound-emitting portion, thereby sealing the sound-emitting portion to reduce the connection gap and isolate noise. At the same time, the fireproof layer A utilizes its elasticity to deform so as to be used in a narrow environment, and the sound insulation layer is made of a flexible sound insulation material and does not affect the normal deformation of the fireproof layer A. Moreover, due to the properties of their materials, the fireproof layer A and the fireproof layer B both have fireproof properties, ensuring that the sound insulation material inside them does not burn while also isolating fires. This solves the problems in the background art that the existing elastic sound-absorbing covers do not have fireproof properties, are not suitable for use in narrow environments, and have large gaps that affect the sound insulation effect.

[0016] 2. The fireproof layer A and the fireproof layer B of the utility model also have certain noise reduction performance due to the nature of the material, which greatly improves the noise isolation effect of the sound-absorbing cover;

[0017] 3. The utility model can conveniently disassemble and assemble the silencer cover through the installation structure;

[0018] 4. The fixed block and the fixed ring of the utility model are provided with beveled edges on their opposite surfaces, so that when installing, the staff need to pull them by the handle, which is more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-4 As shown, the utility model provides a fire-proof grade noise reduction elastic sound-absorbing cover, comprising a fireproof layer A1, a sound insulation layer 2 and a fireproof layer B3;

[0027] Both the fireproof layer A1 and the fireproof layer B3 are made of fire-proof grade noise-reducing thermoplastic elastomer composite materials. The fireproof layer A1 is in the shape of a hood, and the fireproof layer B3 is arranged at its opening, and uses its elasticity to contact with the sound-emitting part for sealing. The sound insulation layer 2 is made of flexible sound insulation material and is arranged on the inner surface of the fireproof layer A1. An installation structure 4 is provided on the outer surface of the fireproof layer A1 near the opening.

[0028] Fire-rated noise-reducing thermoplastic elastomer composites are high-performance polymer materials, typically composed of rubber and polyolefins. They offer excellent resistance to wear, weathering, tearing, impact, ozone, UV, acids, and alkalis. They combine the processing properties of thermoplastics with the physical properties of vulcanized rubber, and incorporate specific flame retardants. These flame retardants can act in the event of a fire, slowing or preventing the spread of flames and reducing the burning speed and intensity, thereby enhancing the material's fire safety.

[0029] The material also exhibits noise reduction properties, a result of its molecular structure and properties. Thermoplastic elastomer composites typically possess certain elastic and damping properties, absorbing and attenuating the propagation of sound waves, thereby achieving a noise reduction effect. For example, the material's internal microstructure can cause sound waves to scatter, reflect, and lose energy as they propagate, thereby reducing sound transmission.

[0030] Furthermore, this material retains the general advantages of thermoplastic elastomers, such as recyclability, excellent mechanical properties, and easy processing. It can be molded into various shapes to meet diverse application requirements through processes such as injection molding. Its excellent mechanical properties provide it with strength and durability during use.

[0031] When in use, the sound-absorbing cover is installed on the sound-emitting part of the equipment through the installation structure 4. After the installation is completed, the fireproof layer B3 is in contact with the sound-emitting part of the equipment (this part is generally convex, and the fireproof layer B3 is squeezed to cause it to deform, and the fireproof layer B3 uses its elasticity to stick to the sound-emitting part). Since the fireproof layer A1 and the fireproof layer B3 are both made of fire-resistant and noise-reducing thermoplastic elastomer composite materials, the fireproof layer B3 and the fireproof layer A1 have a certain elasticity. The fireproof layer B3 uses its elasticity to stick to the sound-emitting part, thereby sealing the sound-emitting part to reduce the connection gap and isolate noise. Part of the noise passes through the fireproof layer B3 and enters the sound-absorbing cover. In the cover body formed by the fire layer A1, sound is absorbed by the sound insulation layer 2. At the same time, the fireproof layer A1 and the fireproof layer B3 also have certain noise reduction performance due to the properties of their materials, which greatly improves the noise isolation effect of the sound-absorbing cover. At the same time, the fireproof layer A1 can be deformed by utilizing its elasticity so that it can be used in a narrow environment, and the sound insulation layer 2 is made of flexible sound insulation material (such as sound insulation cotton, sound insulation felt, polyurethane foam, etc.) and will not affect the normal deformation of the fireproof layer A1. Moreover, the fireproof layer A1 and the fireproof layer B3 also have fireproof performance due to their material properties, ensuring that the sound insulation material inside them does not burn while also isolating the fire.

[0032] The mounting structure 4 includes a circular groove seat 401 fixed on the outer wall of the fireproof layer A1 near the opening, and a fixed circular ring 402 fixed on the sound output part of the equipment. After the circular groove seat 401 is inserted into the fixed circular ring 402, when in use, the raised part of the circular groove seat 401 is inserted into the recessed part of the circular groove seat 401, and finally the two are fixed, thereby fixing the silencer cover to the silencer part of the equipment. The following is the specific structure of the above fixing:

[0033] The upper and lower sides of the circular groove seat 401 are interconnected with the expansion groove seat 403, and the inner top wall of the expansion groove seat 403 is fixed to the fixed block 404 on both sides by springs 409. The upper and lower sides of the fixed ring 402 are provided with grooves 407 for inserting the fixed block 404. The front and rear sides of the expansion groove seat 403 are open. The back of the fixed block 404 is fixedly connected to a horizontal plate 408 near the top, and the top of the horizontal plate 408 is welded with a handle 405 for lifting the fixed block 404. A telescopic rod 406 is fixedly connected to the middle part between the top of the fixed block 404 and the inner top wall of the expansion groove seat 403.

[0034] During installation, first install the fixed ring 402 on the sound output part of the device, then use the handle 405 to act on the horizontal plate 408 to drive the fixed block 404 to move into the expansion slot 403, so as not to block the fixed ring 402 from entering the ring slot 401. At the same time, the telescopic rod 406 is shortened to maintain the linear movement of the fixed block 404, and the spring 409 is also squeezed. Then, insert the ring slot 401 into the fixed ring 402, loosen the handle 405 and rotate the fixed ring 402 to move the fixed ring 402 into the expansion slot 403. The groove 407 on the upper part is rotated to a position flush with the fixing block 404. The fixing block 404 is no longer blocked, and the spring 409 begins to reset the fixing block 404 so that it enters the groove 407, fixing the annular groove seat 401 and the fixing ring 402, and the installation of the sound absorbing cover can be completed. Conversely, the fixing block 404 is pulled into the inside of the expansion groove seat 403 by the handle 405 again to disengage it from the groove 407, and the annular groove seat 401 can be pulled off from the fixing ring 402, releasing the installation of the sound absorbing cover, which is very convenient to disassemble and assemble.

[0035] Furthermore, beveled edges are provided on the opposing surfaces of the fixing block 404 and the fixing ring 402. When the ring groove seat 401 is inserted into the fixing ring 402, the beveled edges on the fixing block 404 and the fixing ring 402 will contact each other, thereby forming an upward thrust on the fixing ring 402, causing it to automatically enter the expansion groove seat 403. In this way, during installation, the staff is required to pull it through the handle 405, which is more convenient for the staff to operate.

[0036] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
