Description

Technical Field

[0001] This application relates to the field of noise reduction technology, and in particular to a mobile soundproof enclosure. Background Technology

[0002] In various settings such as industrial production, construction, equipment testing, and data centers, there are numerous high-noise devices. The noise generated by these devices not only seriously affects the normal work and physical and mental health of workers, but also pollutes the surrounding environment and impacts residents' lives. To effectively control noise, soundproof enclosures are typically used to enclose the noise source and block the noise propagation path.

[0003] Most existing soundproof enclosures are fixed structures, constructed on-site using a steel frame and soundproof panels. These enclosures have the following significant drawbacks: 1. Inconvenient to fix: Once installed, it is difficult to move or modify. If the equipment needs to be repaired, replaced, or the site layout needs to be adjusted, the soundproof enclosure will either be discarded or require a lot of manpower and resources to disassemble and reassemble, which is costly and extremely inflexible.

[0004] 2. Long installation period: On-site construction involves multiple stages such as measurement, welding, installation, and sealing, which takes a long time and affects the production schedule.

[0005] 3. Limited functionality: Traditional soundproof enclosures mainly focus on sound insulation performance, often neglecting environmental control within the enclosure, such as lighting, ventilation, and heat dissipation. This may lead to overheating of equipment or a harsh internal environment, affecting the comfort of equipment operation and personnel entering for maintenance. Utility Model Content

Connecting components are provided on the sides of both the soundproof module and the counterweight module. The connecting components are used to enable quick splicing and separation between adjacent movable soundproof enclosures. The soundproof module is provided with an outer decorative layer, a soundproof layer, a sound-absorbing layer and an interior surface layer from the outside to the inside. Universal wheels are provided at the bottom of the counterweight module. The connecting assembly includes a plug-in structure located on the side of the sound insulation module and a connecting structure located at the edge of the counterweight module. The plug-in structure includes a male plug fixed to one side edge of the sound insulation module and a female plug fixed to one side edge of an adjacent sound insulation module. The male plug and the female plug are adapted to each other. The connecting structure includes a fastener located at the edge of the counterweight module and a connecting member located at the edge of an adjacent counterweight module and adapted to the fastener. When the male plug and the female plug are adapted to each other, the locking pin of the fastener is inserted into the fastener to achieve mechanical locking.

[0008] Furthermore, the male connector is provided with a first permanent magnet, the female connector is provided with a second permanent magnet that is magnetically attracted to the first permanent magnet, and a sealing strip is provided on the mating surface of the male connector and the female connector.

[0009] Furthermore, the counterweight module includes a counterweight box and an installation platform for supporting and connecting the sound insulation module.

[0023] Please see Figures 1 to 5This embodiment proposes a movable soundproof cover, including a soundproof module 100 and a counterweight module 200 disposed at the bottom of the soundproof module 100. Connecting components are provided on the sides of both the soundproof module 100 and the counterweight module 200. The connecting components are used to realize the quick splicing and separation between adjacent movable soundproof covers. The soundproof module 100 is provided with an outer decorative layer, a soundproof layer, a sound-absorbing layer and an interior surface layer from the outside to the inside. Universal wheels 400 are provided at the bottom of the counterweight module 200. It should be noted that in this embodiment, each sound insulation module 100 adopts a composite acoustic structure. The outermost layer is the outer decorative layer, made of 0.8mm thick galvanized steel plate and 1.2mm thick galvanized keel, combining structural strength and aesthetics. Inward is the sound insulation layer, made of 2mm thick cold-rolled steel plate, whose high surface density effectively blocks the propagation of sound waves and is the main sound insulation component. Further inward is the sound absorption layer, made of 50mm thick centrifugal glass wool board with a density of 48kg / m³, wrapped with sound-permeable non-woven fabric. This absorbs sound energy that penetrates the sound insulation layer and enters the enclosure, reducing internal reverberation and thus improving overall sound insulation. The innermost layer is the interior surface layer, made of perforated aluminum plate with a perforation rate of 25%. Its pores allow sound waves to enter the sound absorption layer behind it, while also protecting the sound-absorbing material and providing aesthetic appeal and easy cleaning.

[0024] Furthermore, the connecting assembly includes a plug-in structure located on the side of the sound insulation module 100 and a connecting structure located at the edge of the counterweight module 200. The plug-in structure includes a male plug-in connector 310 fixed to one side edge of the sound insulation module 100 and a female plug-in groove 320 fixed to one side edge of an adjacent sound insulation module 100. The male plug-in connector 310 is adapted to the female plug-in groove 320. The connecting structure includes a fastener 510 located at the edge of the counterweight module 200 and a connecting member 520 located at the edge of an adjacent counterweight module 200 and adapted to the fastener 510. When the male plug-in connector 310 is adapted to the female plug-in groove 320, the locking pin of the fastener 510 is inserted into the fastener 510 to achieve mechanical locking.

[0025] Specifically, the male connector 310 is provided with a first permanent magnet, the second female connector 320 is provided with a second permanent magnet that is magnetically attracted to the first permanent magnet, and a sealing strip is also provided on the mating surface of the male connector 310 and the female connector 320.

[0026] It should be noted that when assembling the soundproof enclosure, simply align the male connector 310 with the female connector 320 and bring them close together; the magnetic force will automatically guide them to accurately align and engage, ensuring a tight seal at the joint. The sealing strip at the joint (made of EPDM rubber foam) is compressed, achieving excellent acoustic sealing.

[0027] Understandably, this is achieved by setting up a connection structure. A fastener 510 is provided at the edge of the counterweight module 200, and a connector 520 adapted to the fastener 510 is provided at the edge of the adjacent configuration module. When the male connector 310 is adapted to the female connector 320, the locking pin of the fastener 510 is inserted into the fastener 510 to achieve mechanical locking. When disassembly is required, the locking pin is pressed to disengage it from the fastener 510, thereby releasing the fastener 510 and the connector 520.

[0028] Furthermore, the counterweight module 200 includes a counterweight box and an installation platform for supporting and connecting the sound insulation module 100. The casters 400 are equipped with locking structures and are located at the four corners of the counterweight box.

[0029] It should be noted that in this embodiment, the counterweight box is constructed of a sturdy steel frame, with four casters 400 with brakes installed at the bottom corners, allowing for easy movement and secure positioning. The top of the counterweight box is an installation platform with multiple positioning protrusions welded on it. The bottom of the sound insulation module 100 is machined with corresponding positioning grooves (not shown in the figure). During installation, the module is placed down by aligning the grooves on its bottom with the positioning protrusions, achieving quick and accurate positioning and providing a reference for subsequent vertical splicing.

[0030] In this embodiment, a temperature and humidity sensor and a ventilation and noise reduction unit are provided inside the sound insulation module 100. The ventilation and noise reduction unit includes an air intake noise reduction louver 700 provided on the bottom outer wall of the sound insulation module 100 and an exhaust noise reduction device 600 provided on the top outer wall of the sound insulation module 100. A low-speed fan is provided inside the air intake noise reduction louver 700.

[0031] Understandably, a ventilation and noise reduction unit is installed to ensure equipment heat dissipation. The air intake noise reduction louver 700 is filled with sound-absorbing material. An exhaust silencer 600 is installed on the top outer wall of the sound insulation module 100. The exhaust silencer 600 also has a noise reduction channel structure, and a low-speed fan is installed inside the air intake noise reduction louver 700. During operation, the fan starts, drawing in cool air from outside the enclosure through the air intake noise reduction louver 700. After the air flows through the equipment and carries away the heat, the hot air is discharged from the exhaust silencer 600. The noise reduction structure at the inlet and outlet effectively prevents noise leakage from the ventilation openings.

[0032] Specifically, a lighting unit is provided on the top of the sound insulation module 100. The lighting unit includes a power supply and a lighting device embedded in the sound insulation module 100, and the power supply is electrically connected to the lighting device. An LED panel light is embedded in the top of the sound insulation module 100 as the lighting unit, providing bright and shadowless lighting for the inside of the enclosure.

[0033] Furthermore, a servo motor is installed inside the counterweight box, and the servo motor is connected to the casters 400 to realize the reciprocating linear displacement of the movable soundproof enclosure. It can be understood that after the soundproof enclosure is disassembled, the servo motor drives the casters 400 to perform reciprocating linear displacement, thereby moving the soundproof enclosure body. This makes the soundproof enclosure more convenient to use when maintenance, cleaning, or replacement of internal noise source equipment is required, greatly reducing the workload of operators.

[0034] In summary, the movable soundproof enclosure described in the above embodiments of this utility model, through its modular design and connecting components, allows users to freely assemble soundproof rooms of the required size and shape according to the size and shape of the noise source. The casters enable it to be easily moved to any desired location, completely solving the problem of fixed soundproof enclosures being immovable. The connecting components avoid traditional on-site welding and complex installation processes, allowing assembly or disassembly to be completed quickly by a single person or with a small number of personnel, greatly saving time and labor costs. The use of a sound insulation-sound absorption composite wall structure, combined with connecting components with sealing strips, ensures that the entire enclosure has high sound insulation and effectively suppresses noise leakage.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
