Description

Technical Field

[0001] This utility model relates to the field of soundproof enclosure technology, specifically a movable modular splicing soundproof enclosure. Background Technology

[0002] In modern industrial production, with the rapid development of manufacturing and the increasing size and speed of production equipment, the high-intensity noise pollution generated by production machinery in factories has become a significant factor restricting the construction of green factories and the protection of employees' occupational health. Currently, soundproof enclosures, a traditional technology, are widely used as a solution in noise reduction projects in many industries such as machining, automobile manufacturing, and building materials production.

[0003] The existing soundproof enclosures have a relatively simple soundproofing structure design, which only uses simple sound-absorbing materials. Most of the soundproof enclosures are fixedly installed at the noise source, which makes it difficult to adapt to the complex and ever-changing machine layout in the factory. When the production process is adjusted or the equipment position is changed, it is often necessary to rebuild the soundproofing facilities, which is time-consuming and labor-intensive. In addition, the existing soundproof enclosures are not tightly integrated with the internal structure of the factory, and the installation process is cumbersome and lacks flexibility. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a movable modular sound-absorbing enclosure. It utilizes a multi-layered composite sound-absorbing structure consisting of an outer perforated metal plate, a middle multi-cavity sound-absorbing module, and an inner microporous sound-absorbing plate, forming a progressive sound-absorbing system that improves the sound absorption effect. Furthermore, the multi-cavity sound-absorbing module employs a magnetic splicing structure, allowing for quick assembly and disassembly without additional tools or fasteners. The sound-absorbing enclosure components are also adjustable within a certain angle range to adapt to factory space constraints. Combined with support components, this enclosure flexibly adapts to complex machine layouts within the factory, thus solving background noise issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A movable modular splicing soundproof enclosure includes mounting plates, wherein two sets of mounting plates are provided, and a support component is installed on the top of each set of mounting plates, and a soundproof enclosure component is provided between the two sets of support components.

[0007] The sound-absorbing enclosure assembly includes a base plate and a top plate. The top plate is positioned above the base plate. The top front side of the base plate and the bottom front side of the top plate are each provided with a second sliding groove. The top rear side of the base plate and the bottom rear side of the top plate are each provided with a first sliding groove. A microporous sound-absorbing plate is slidably connected between the two sets of second sliding grooves. A perforated metal plate is slidably connected between the two sets of first sliding grooves. Several multi-cavity sound-absorbing modules are provided between the perforated metal plate and the microporous sound-absorbing plate. A magnetic connection mechanism is provided between adjacent sides of each pair of multi-cavity sound-absorbing modules.

[0008] Preferably, the magnetic connection mechanism includes a first insert and a second insert. Slots are provided on all four sides of the multi-cavity silencing modules. The first insert and the second insert are fixedly installed inside the slots by screws. The first insert has two sets of insertion holes on the side near the second insert.

[0009] A magnetic block is fixedly connected inside the socket. Two sets of metal rods are fixedly connected to the side of the second plug near the first plug. The metal rods are inserted into the socket, and the end of the metal rod near the magnetic block abuts against the magnetic block.

[0010] Preferably, the support assembly includes a fixed cylinder, which is fixedly connected to the middle of the top side of the mounting plate. A lifting block is slidably connected inside the fixed cylinder, and a rotating shaft is fixedly connected to the top side of the lifting block.

[0011] Mounting box one and mounting box two are respectively provided on the left and right sides of the rotating shaft. Several sleeves are fixedly connected to the side of mounting box one and mounting box two that are close to each other. Several sleeves are fitted on the rotating shaft. An adjustment mechanism is installed inside the fixed sleeve.

[0012] Preferably, the adjusting mechanism includes a rotating rod that rotatably passes through the middle of the mounting plate. Limiting plates are fixedly connected to both the top and bottom sides of the rotating rod. The two sets of limiting plates abut against the upper and lower sides of the mounting plate, respectively. A screw is fixedly connected to the top side of the limiting plate located on the top side. A threaded groove is formed in the middle of the bottom side of the lifting block, and the screw is threaded into the inside of the threaded groove. A rotating handle is fixedly connected to the bottom side of the limiting plate located on the bottom side.

[0013] Preferably, the left and right ends of the base plate are respectively fixed to the inner bottom sides of mounting box one and mounting box two by bolts, and the left and right ends of the top plate are respectively fixed to the inner top sides of mounting box one and mounting box two by bolts.

[0014] Preferably, both mounting box one and mounting box two are provided with elastic rubber pads inside, and the left and right sides of the perforated metal plate and the left and right sides of the microporous sound-absorbing plate respectively abut against the two sets of elastic rubber pads.

[0015] Preferably, a limiting plate is fixedly connected to the top end of the rotating shaft.

[0016] Preferably, the mounting plate is equipped with brakeable casters on both the front and rear sides of its bottom.

[0018] Preferably, the multi-cavity sound-absorbing module has multiple honeycomb-shaped sound-absorbing cavities inside, and glass fiber sound-absorbing cotton is filled between each layer of sound-absorbing cavities.

[0019] This utility model provides a movable modular splicing soundproof enclosure. Compared with the prior art, it has the following advantages:

[0020] On the one hand, this movable modular soundproof enclosure, while seemingly simple in structure, actually features highly integrated modular parts and components. These can be cleverly combined and installed to form a modular soundproof enclosure. In its specific structural design, mounting boxes one and two are sleeved onto a rotating shaft, allowing for flexible rotation around the shaft and thus enabling the soundproof enclosure components to be adjusted within a certain angle range. When encountering corners or narrow passages within the factory, the angle adjustment can adapt to space constraints. Combined with the adjustment mechanism and brakeable casters in the support components, this enclosure can not only match the height of different equipment but also flexibly adapt to complex machine layouts within the factory through angle adjustment.

[0021] On another front, this movable modular soundproof enclosure utilizes a multi-layered composite soundproofing structure consisting of an outer perforated metal plate, a middle multi-cavity soundproofing module, and an inner microporous sound-absorbing plate. This multi-layered structure forms a progressive soundproofing system. The perforated metal plate initially reflects and scatters noise, while the multi-layered honeycomb sound-absorbing cavities within the multi-cavity soundproofing module, combined with fiberglass sound-absorbing cotton, achieve efficient sound absorption through multiple reflections and dissipation of sound waves within the cavities. Simultaneously, the microporous sound-absorbing plate further absorbs residual sound waves, significantly enhancing the soundproofing effect through layered stacking. Furthermore, the multi-cavity soundproofing module employs a magnetic splicing structure, allowing for quick assembly and disassembly without additional tools or fasteners.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-3 As shown, this utility model provides a movable modular splicing soundproof enclosure, including a mounting plate 1, which is provided in two sets. Support components are installed on the top of both sets of mounting plates 1, and a soundproof enclosure component is provided between the two sets of support components.

[0032] When in use, the movable modular soundproof enclosure is supported by the support components on the top of the two sets of mounting plates 1, which reduces the noise generated by the factory equipment during operation.

[0033] The sound-absorbing enclosure assembly includes a base plate 3 and a top plate 7. The top plate 7 is positioned above the base plate 3. The top front side of the base plate 3 and the bottom front side of the top plate 7 are both provided with a second sliding groove 27. The top rear side of the base plate 3 and the bottom rear side of the top plate 7 are both provided with a first sliding groove 26. A microporous sound-absorbing plate 5 is slidably connected between the two sets of second sliding grooves 27. A perforated metal plate 4 is slidably connected between the two sets of first sliding grooves 26. Several multi-cavity sound-absorbing modules 6 are provided between the perforated metal plate 4 and the microporous sound-absorbing plate 5. A magnetic connection mechanism is provided between each pair of adjacent sides of the several multi-cavity sound-absorbing modules 6.

[0034] like Figures 5-7 As shown, the magnetic connection mechanism includes a first plug 10 and a second plug 11. Each of the four sides of the multi-cavity silencing modules 6 is provided with a slot 9. The first plug 10 and the second plug 11 are fixedly installed inside the slot 9 by screws. The first plug 10 is provided with two sets of insertion holes 12 on the side near the second plug 11. A magnetic block 13 is fixedly connected inside the insertion hole 12. The second plug 11 is fixedly connected with two sets of metal rods 14 on the side near the first plug 10. The metal rods 14 are inserted into the inside of the insertion hole 12, and the end of the metal rod 14 near the magnetic block 13 abuts against the magnetic block 13.

[0035] When the noise-absorbing enclosure assembly is in operation, the base plate 3 and the top plate 7 are arranged vertically to form a frame. The sliding groove 27 on the front top side of the base plate 3 and the front bottom side of the top plate 7 allows the micro-perforated sound-absorbing plate 5 to slide and be installed. The sliding groove 26 on the rear top side of the base plate 3 and the rear bottom side of the top plate 7 allows the perforated metal plate 4 to slide and be installed. Several multi-cavity noise-absorbing modules 6 between the two are spliced ​​together on adjacent sides by insert blocks 10 and 11. During splicing, insert blocks 10 and 11 are fixedly installed in the slots 9 on adjacent sides of the two sets of multi-cavity noise-absorbing modules 6 by screws. The magnetic block 13 in the insertion hole 12 of insert block 10 and the metal rod 14 of insert block 11 magnetically abut against each other, so that the multi-cavity noise-absorbing modules 6 are spliced ​​and fixed. The noise is silencing sequentially through the perforated metal plate 4, the multi-cavity noise-absorbing modules 6, and the micro-perforated sound-absorbing plate 5.

[0036] The support assembly includes a fixed cylinder 15, which is fixedly connected to the top center of the mounting plate 1. A lifting block 16 is slidably connected inside the fixed cylinder 15. A rotating shaft 17 is fixedly connected to the top side of the lifting block 16. Mounting box 1 28 and mounting box 29 are respectively provided on the left and right sides of the rotating shaft 17. Several sleeves 19 are fixedly connected to the side of mounting box 1 28 and mounting box 29 that are close to each other. Several sleeves 19 are all sleeved on the rotating shaft 17. An adjustment mechanism is installed inside the fixed cylinder 15.

[0037] The adjustment mechanism includes a rotating rod 21, which is rotatably inserted through the middle of the mounting plate 1. Limiting plates 22 are fixedly connected to the top and bottom sides of the rotating rod 21. The two sets of limiting plates 22 abut against the upper and lower sides of the mounting plate 1 respectively. A screw 24 is fixedly connected to the top side of the limiting plate 22 located on the top side. A threaded groove 25 is opened in the middle of the bottom side of the lifting block 16. The screw 24 is threaded into the inside of the threaded groove 25. A rotating handle 23 is fixedly connected to the bottom side of the limiting plate 22 located on the bottom side.

[0038] The left and right ends of the base plate 3 are respectively fixed to the bottom inside of mounting box 1 28 and mounting box 2 29 by bolts, and the left and right ends of the top plate 7 are respectively fixed to the top inside of mounting box 1 28 and mounting box 2 29 by bolts.

[0039] When the support assembly is working, the fixed cylinder 15 is fixed to the middle of the top side of the mounting plate 1. Rotating the rotating handle 23 drives the rotating rod 21 to rotate. The rotating rod 21 drives the screw 24 to rotate through the top side limiting plate 22. The screw 24 is threadedly engaged with the threaded groove 25 on the bottom side of the lifting block 16, so that the lifting block 16 slides up and down in the fixed cylinder 15, thereby adjusting the height of the rotating shaft 17. The mounting boxes 1 28 and 29 on the left and right sides of the rotating shaft 17 are sleeved on the rotating shaft 17 through the sleeve 19 and can rotate around the rotating shaft 17. The bottom plate 3 and the top plate 7 are fixed in the mounting boxes 1 28 and 29 through bolts.

[0040] Both mounting box 1 (28) and mounting box 2 (29) are equipped with elastic rubber pads 8. The left and right sides of the perforated metal plate 4 and the left and right sides of the microporous sound-absorbing plate 5 respectively abut against the two sets of elastic rubber pads 8. When the perforated metal plate 4 and the microporous sound-absorbing plate 5 are installed in mounting box 1 (28) and mounting box 2 (29), their left and right sides abut against the elastic rubber pads 8. The elastic rubber pads 8, through their own elastic deformation, play a buffering and shock-absorbing role for the perforated metal plate 4 and the microporous sound-absorbing plate 5.

[0041] A limiting plate 20 is fixedly connected to the top of the rotating shaft 17. The limiting plate 20 is fixed to the top of the rotating shaft 17 to prevent the mounting box 28 and the mounting box 29 from coming off upward when they are sleeved on the rotating shaft 17 through the sleeve 19. It also limits the position of the mounting box 28 and the mounting box 29 on the rotating shaft 17, ensuring their stability when rotating around the rotating shaft 17.

[0042] Brake casters 2 are installed on the front and rear sides of the bottom of the mounting plate 1. When the fence is pushed, the brake casters 2 roll to move the fence. After reaching the designated position, the brake casters 2 are locked by the braking device to fix the fence to the ground, thus realizing the function of moving and positioning the fence.

[0043] The front and rear sides of the fixed cylinder 15 are fixedly connected with reinforcing connecting plates 18. The reinforcing connecting plates 18 are fixed to the front and rear sides of the fixed cylinder 15. By increasing the connection area between the fixed cylinder 15 and the mounting plate 1, the installation strength and stability of the fixed cylinder 15 in the middle of the top side of the mounting plate 1 are enhanced, making the fixed cylinder 15 more secure when supporting the lifting block 16 and the soundproof enclosure assembly, and less prone to deformation or loosening.

[0044] The multi-cavity silencing module 6 has multiple honeycomb-shaped sound-absorbing cavities inside, with glass fiber sound-absorbing cotton filling between each cavity. The multiple honeycomb-shaped sound-absorbing cavities inside the multi-cavity silencing module 6 form multiple independent sound-absorbing spaces. When noise is introduced, the sound waves are reflected and refracted multiple times in the honeycomb-shaped sound-absorbing cavities, and friction occurs with the cavity walls, gradually dissipating energy. The porous structure of the glass fiber sound-absorbing cotton filling between each cavity further absorbs the sound waves. Through the synergistic effect of the multiple honeycomb-shaped sound-absorbing cavities and the glass fiber sound-absorbing cotton, efficient noise absorption is achieved.

[0045] When using this movable modular soundproof enclosure, brakeable casters 2 are installed on the front and rear sides of the bottom of both sets of mounting plates 1. When the enclosure is pushed, the brakeable casters 2 roll to move the enclosure. After reaching the designated position, the brakeable casters 2 are locked by the braking device to fix the enclosure to the ground, thus achieving flexible installation.

[0046] During installation and assembly, insert 10 and insert 21 are respectively fixed in the slots 9 on the adjacent sides of the two sets of multi-cavity silencing modules 6 by screws. The magnetic block 13 in the insertion hole 12 of insert 10 and the metal rod 14 of insert 21 are magnetically attracted to each other, so that the multi-cavity silencing module 6 is spliced ​​and fixed. The noise is silencing in sequence through the perforated metal plate 4, the multi-cavity silencing module 6, and the micro-perforated sound-absorbing plate 5.
