Description

Technical Field

[0001] This utility model relates to the field of sound insulation and noise reduction technology, and in particular, to a mobile sound insulation and noise reduction device. Background Technology

[0002] During construction, some equipment generates a lot of noise when it is working, which can affect the hearing of local residents and on-site construction workers. To reduce the impact of noise, soundproof and noise-reducing sheds are usually built on the construction site.

[0003] Traditional soundproof and noise-reducing tents are typically fixed in specific locations, making them difficult to move and requiring transport to the construction site, which is time-consuming and labor-intensive. Chinese Patent Publication No. CN216840838U discloses a mobile noise-reducing and soundproofing tent, including a U-shaped frame. A protective door is rotatably connected to the front end of the frame, and four rollers are installed at the bottom. Two sets of placement components are symmetrically arranged at both ends of the frame. A handle is installed at the front end of the protective door, and a U-shaped plate is installed at the top of the frame. A buffer component is located within the U-shaped plate. The frame and the protective door are connected by a buckle. A sound-insulating panel filled with sound-absorbing cotton is installed inside the frame. This patent allows for mobility via the rollers and the placement components allow the tent to be placed on the construction site, making it convenient, time-saving, and labor-saving. However, the patented design relies solely on rollers to support the entire scaffold during placement and use, which is insufficient to guarantee its stability. This can easily cause the scaffold to move, sway, or tip over, affecting construction and use. Furthermore, the patented placement components cannot place the scaffold stably on uneven construction sites. Uneven construction sites can also prevent the bottom of the scaffold from contacting the ground, allowing noise to escape through the gap between the bottom of the scaffold and the ground, resulting in poor sound insulation and noise reduction.

[0007] The fixing mechanism is installed on the side wall of the shed, with its bottom extending out from the bottom of the shed. It is used to be inserted into the construction site to fix the shed.

[0008] The movable mechanism is installed at the bottom of the canopy in a height-adjustable manner relative to the canopy body. It is used to support the fixed mechanism on the ground through a lifting action so as to drive the canopy body to move.

[0009] The noise-reducing curtain is retractable and attached to the bottom of the shed to seal the gap between the bottom of the shed and the construction site.

[0010] Furthermore, the shed includes a frame and a soundproof door rotatably connected to the frame. The inner wall of the frame has a groove, and the soundproofing component is installed in the groove.

[0011] Furthermore, the fixing mechanism includes a fixing plate and fixing teeth fixed to the bottom of the fixing plate. The fixing plate is installed on the inner wall of the frame and there are two symmetrically arranged inside the frame.

[0012] The bottom end of the fixing tooth protrudes from the bottom end of the canopy.

[0013] Furthermore, the moving mechanism includes a moving component for moving the shed body and a drive component for controlling the lifting and lowering of the moving component. The drive component is mounted on the shed frame, and the moving component is located below the fixed plate and moves in conjunction with the fixed teeth along the height direction.

[0014] Furthermore, the moving component includes a lifting plate and rollers fixed to the bottom of the lifting plate, with the end of the lifting plate away from the rollers fixed to the output end of the drive component;

[0015] The lifting plate has through holes corresponding to the fixed teeth.

[0016] Furthermore, the drive assembly includes a gear plate, a rack meshing with the gear plate, and a rotating shaft for controlling the rotation of the gear plate. The gear plate is located above the fixed plate and is rotatably mounted on the inner wall of the frame. The rack moves vertically through the fixed plate and is fixed to the lifting plate.

[0017] One end of the shaft is mounted on the gear plate, and the other end extends out of the outer wall of the frame.

[0018] Furthermore, the drive assembly also includes a mounting housing covering the outside of the gear plate and rack, the mounting housing being fixed to the frame;

[0019] The mounting housing is equipped with a limiting block, and a guide groove is formed between the limiting block and the inner sidewall of the mounting housing. The rack moves along the height direction and passes through the guide groove and can extend out of the mounting housing.

[0021] Furthermore, the soundproof door includes a door panel and a magnetic block. The first end of the door panel is hinged to the frame, the magnetic block is installed at the second end of the door panel, and the frame has a magnetic groove corresponding to the magnetic block.

[0022] A handle is installed on the side of the door panel away from the shelf.

[0023] Furthermore, a protective frame is also installed on the scaffold, which includes a protective plate installed on the top of the scaffold, a buffer post fixed to the top of the protective plate, and a protective net installed on the buffer post.

[0024] This utility model has the following beneficial effects:

[0025] This utility model discloses a mobile sound insulation and noise reduction device. It utilizes a fixed mechanism extending from the bottom of the shed and a movable mechanism that is adjustable in height relative to the shed. The movable mechanism supports the shed on the ground through its lifting motion. Lowering the movable mechanism moves the shed upwards, lifting the bottom of the fixed mechanism off the ground, thus enabling convenient, time-saving, and labor-saving movement. Raising the movable mechanism moves the shed downwards, allowing the fixed mechanism to descend and engage with the shed on the construction site, securing it in place. The fixed mechanism, through its engagement with the construction site, ensures stable placement on uneven surfaces, preventing displacement, swaying, or tilting, thus improving stability. It is suitable for complex construction sites, highly adaptable, and versatile. Furthermore, the direct engagement method eliminates complex installation procedures, reducing labor and time costs. The coordination between the positioning mechanism, the fixed mechanism, and the movable mechanism allows for quick switching between the fixed and movable states of the shed, improving the efficiency of equipment adjustment within the construction site. By installing sound-absorbing components inside the shed, the transmission of noise from within the shed to the outside can be effectively reduced. Simultaneously, noise-reducing curtains installed at the bottom of the shed can seal the gap between the bottom of the shed and the construction site after the shed is fixed in place, preventing noise from escaping through these gaps and significantly improving sound insulation. Furthermore, the noise-reducing curtains can adaptively expand and contract according to the flatness of the site, effectively filling the gap between the bottom of the shed and the construction site, offering high flexibility. The combination of the internal sound-absorbing components and the noise-reducing curtains at the bottom of the shed forms a fully enclosed sound barrier, significantly reducing construction noise leakage and achieving highly efficient sound insulation and noise reduction.

[0026] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0035] like Figure 1 and Figure 2 As shown, the mobile sound insulation and noise reduction device of this embodiment includes a canopy 100, a fixing mechanism 200, a moving mechanism 300, and a noise reduction curtain 400. The lower end of the canopy 100 has an open structure to facilitate enclosure around the construction site for sound insulation and noise reduction. Sound insulation components 1011 are installed on the inner wall of the canopy 100 to absorb sound within the canopy 100, effectively reducing the transmission of noise from inside the canopy 100 to the outside. Preferably, the sound insulation component 1011 is made of sound-absorbing cotton; alternatively, the sound insulation component 1011 can also be a sound insulation board.

[0036] In this embodiment, both the fixing mechanism 200 and the moving mechanism 300 are located at the bottom of the shed 100 and installed on the inner wall of the shed 100. The bottom of the fixing mechanism 200 extends beyond the bottom end of the shed 100 to facilitate insertion into the construction site for fixing the shed 100. The fixing mechanism 200 secures the shed 100 by interlocking with the construction site, ensuring stable placement of the shed 100 on uneven construction sites, preventing displacement, shaking, or tilting, thus improving the stability of the shed 100. It is suitable for complex construction sites, highly adaptable, and versatile. Furthermore, the direct insertion method eliminates the need for complex installation procedures, reducing labor and time costs. The moving mechanism 300 is adjustable in height relative to the shed 100. It can be raised and lowered to support the shed 100 on the ground, lifting the fixing mechanism 200 off the ground to move the shed 100. In this embodiment, the moving mechanism 300 is movably inserted into the fixed mechanism 200 along the height direction. Thus, by controlling the downward movement of the moving mechanism 300, the canopy 100 can be moved upwards, raising the bottom of the fixed mechanism 200 off the ground, thereby enabling convenient, time-saving, and labor-saving movement of the canopy 100. Conversely, by controlling the upward movement of the moving mechanism 300, the canopy 100 can be moved downwards, allowing the fixed mechanism 200 to descend with the canopy 100 and be inserted into the construction site, thus fixing the canopy 100. Through the cooperation of the positioning mechanism, the fixed mechanism 200, and the moving mechanism 300, the fixed and moving states of the canopy 100 can be quickly switched, improving the efficiency of equipment adjustment within the construction site. Optionally, the moving mechanism 300 can also be staggered from the fixed mechanism 200.

[0037] Preferably, the noise-reducing curtain 400 is made of U-shaped rubber or soft sound-insulating material. The noise-reducing curtain 400 is telescopically connected to the bottom of the shed 100. After the shed 100 is moved to a designated position, it naturally hangs down to cover the gap between the bottom of the shed 100 and the construction site, forming a sound barrier to prevent noise leakage from the bottom, significantly improving the sound insulation effect. Furthermore, the noise-reducing curtain 400 can expand and contract with the ground undulations, adaptively adjusting to the flatness of the site, sealing the gap between the bottom of the shed 100 and the construction site, offering high flexibility and adaptability. Through the combination of the sound-insulating component 1011 inside the shed 100 and the noise-reducing curtain 400 at the bottom of the shed 100, the shed 100 can form a fully enclosed sound barrier, significantly reducing construction noise leakage and achieving efficient sound insulation and noise reduction.

[0038] like Figure 1 and Figure 2As shown, the shed 100 includes a shed frame 101 and a soundproof door 102. In this embodiment, the shed frame 101 is a three-sided enclosed structure with a U-shaped cross-section. The bottom of the shed frame 101 is an open structure and a doorway is provided on the side. The soundproof door 102 is rotatably connected to the shed frame 101 to open and close the doorway, thereby pushing the shed frame 101 into a designated position in the construction site through the doorway, so that the shed 100 can achieve sound insulation and noise reduction through enclosure.

[0039] The inner wall of the canopy 101 has grooves, and multiple grooves are evenly distributed on the inner wall of the canopy 101. Sound insulation components 1011 are installed within these grooves. Preferably, the sound insulation components 1011 are made of sound-absorbing cotton, which is embedded in the grooves to absorb noise generated during the operation of the canopy 100, further reducing the transmission of noise to the outside. Optionally, the sound insulation components 1011 can also be sound-insulating panels.

[0040] like Figure 1 and Figure 3 As shown, the fixing mechanism 200 includes a fixing plate 201 and fixing teeth 202 fixed to the bottom of the fixing plate 201. The fixing plate 201 is installed on the inner wall of the frame 101 and two are symmetrically arranged inside the frame 101. The bottom of the fixing teeth 202 protrudes from the bottom of the frame 100 to facilitate insertion with the ground of the construction site, so that the frame 100 can be stably placed on the ground. Preferably, multiple fixing teeth 202 are evenly distributed along the length of the fixing plate 201 to enhance the stability of the insertion and fixing with the construction site. At the same time, multiple fixing teeth 202 can cooperate to level the frame 100 on uneven ground, so that the frame 100 can be placed stably on the ground, increasing the contact area between the bottom of the frame 100 and the ground. Preferably, the fixing tooth 202 is made of steel and has a cylindrical structure. The end of the fixing tooth 202 away from the fixing plate 201 has a conical structure, which can penetrate hard soil layers, so that the fixing tooth 202 can be firmly inserted into the construction site, thereby improving the stability of the shed 100.

[0041] like Figure 1 , Figure 2 and Figure 4As shown, the moving mechanism 300 includes a moving component 301 for moving the shed 100 and a driving component 302 for controlling the lifting and lowering of the moving component 301. The driving component 302 is located above the fixed plate 201 and installed on the inner wall of the shed 100. The output end of the driving component 302 is movably inserted into the fixed plate 201 along the height direction. The moving component 301 is located below the fixed plate 201 and fixed to the output end of the driving component 302. The fixing tooth 202 is movably inserted into the moving component 301 along the height direction. Thus, the movable component 301 can be raised and lowered relative to the shed 100 under the control of the drive component 302. When the shed 100 needs to be fixed, the drive component 302 is controlled to raise the movable component 301. At this time, the shed 100 is lowered relative to the movable component 301, and the fixing teeth 202 extend from the movable component 301 until they contact the ground for insertion, locking the movable component 301, so that the shed 100 can be stably placed in the construction site. When the shed 100 needs to be moved to a designated position, the drive component 302 is controlled to lower the movable component 301. At this time, the shed 100 is raised relative to the movable component 301 until the bottom of the shed 100 and the bottom of the fixing teeth 202 are both supported to the ground, locking the movable component 301, and then pushing or pulling the shed 100 can realize the movement of the shed 100.

[0042] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the moving component 301 includes a lifting plate 3011 and rollers 3012 fixed to the bottom of the lifting plate 3011. The end of the lifting plate 3011 away from the rollers 3012 is fixed to the output end of the driving component 302. Preferably, the output end of the driving component 302 is fixed to the middle of the lifting plate 3011 to ensure uniform force application to the lifting plate 3011. Preferably, a fixing block is provided between the lifting plate 3011 and the rollers 3012. Multiple fixing blocks are evenly distributed along the length of the lifting plate 3011 and fixed to it. Multiple rollers 3012 are rotatably installed within the fixing blocks, forming an integral part with them. This enhances the connection strength between the rollers 3012 and the lifting plate 3011 and allows for lateral limiting of the rollers 3012, ensuring smooth movement of the shed 100 and improving movement efficiency. Preferably, the rollers 3012 have a self-locking function to prevent the shed 100 from continuing to move or shifting after reaching the designated position. Preferably, the roller 3012 is a caster wheel, which improves the convenience and flexibility of movement.

[0043] The lifting plate 3011 has a through hole 3013 corresponding to the fixing tooth 202, so that the fixing tooth 202 can move through it. When the lifting plate 3011 rises, the bottom end of the fixing tooth 202 can extend from the bottom end of the lifting plate 3011 and insert into the ground to fix the shed 100. Preferably, the diameter of the through hole 3013 is slightly larger than the outer diameter of the fixing tooth 202 to ensure that the fixing tooth 202 slides smoothly in the through hole 3013, avoids the fixing tooth 202 being stuck by the lifting plate 3011, and prevents the fixing tooth 202 from being unable to contact the ground for insertion and fixation.

[0044] like Figure 2 and Figure 4 As shown, the drive assembly 302 includes a gear 3021, a rack 3022, and a rotating shaft 3023. Specifically, the gear 3021 is located above the fixed plate 201 and is rotatably mounted on the inner wall of the frame 101. The rack 3022 is located on one side of the gear 3021, with one end meshing with the gear 3021 and the other end movably passing through the fixed plate 201 and fixed to the lifting plate 3011 below the fixed plate 201. The rotating shaft 3023 is secured to the central shaft of the gear 3021 and extends out of the frame 101 to movably engage with the frame 101. A handle is installed at the end of the rotating shaft 3023 away from the gear 3021. The handle is located outside the frame 101. The rotating shaft 3023 and / or the handle are provided with a locking structure for locking the gear 3021 and the rack 3022. Therefore, turning the handle can control the rotation of the gear plate 3021, and the gear plate 3021 and the rack 3022 mesh to drive the lifting plate 3011 to rise and fall.

[0045] like Figure 2 and Figure 4As shown, the drive assembly 302 also includes a mounting housing 500, which covers the outside of the gear disk 3021 and the rack 3022 and is fixed to the frame 101. The end of the mounting housing 500 near the fixing plate 201 has an open structure to allow the rack 3022 to extend. The rack 3022 includes a toothed section and a straight section. The toothed section is located at the end near the gear disk 3021 to mesh with the gear disk 3021, and the straight section is located at the end near the fixing plate 201 to facilitate insertion into the fixing plate 201. A limiting block 501 is provided inside the mounting housing 500. The limiting block 501 is located below the gear disk 3021 and forms a guide groove between it and the inner side wall of the mounting housing 500. The rack 3022 moves along the height direction and passes through the guide groove. Thus, the rack 3022 is limited and guided by the guide groove within the mounting housing 500, which can ensure that the rack 3022 moves along the height direction and prevents deviation. At the same time, the top of the mounting housing 500 can limit the top of the rack 3022 to prevent the tooth segments of the rack 3022 from losing their meshing connection with the gear disk 3021. Preferably, in this embodiment, a limiting plate is provided on the side of the lifting plate 3011 away from the roller 3012. The limiting plate is fixed to both ends of the lifting plate 3011 to abut against the fixing plate 201 to limit the rack 3022, prevent the straight section of the rack 3022 from contacting the gear plate 3021, and avoid the loss of meshing connection between the rack 3022 and the gear plate 3021.

[0046] Alternatively, in another embodiment, the drive component 302 may also be a motor, which is located above the fixed plate 201 and fixed to the frame 101. The output shaft of the motor is movably inserted into the fixed plate 201 and fixed to the lifting plate 3011, so that the lifting plate 3011 can be controlled by starting and stopping the motor.

[0047] like Figure 1 and Figure 2 As shown, the noise-reducing curtain 400 is installed at the bottom of the canopy frame 101, enclosing it. The cross-section of the noise-reducing curtain 400 is U-shaped to enclose and seal the bottom of the canopy frame 101 and the gap between the bottom of the canopy frame 101 and the ground, preventing noise leakage from the bottom gap and further enhancing the sound insulation and noise reduction effect. Preferably, the bottom of the noise-reducing curtain 400 is provided with a wear-resistant pad to reduce the wear of the ground on the noise-reducing curtain 400 at the construction site and improve the service life of the noise-reducing curtain 400. Preferably, the noise-reducing curtain 400 has a sound-insulating interlayer inside to further enhance the sound insulation effect. Optionally, the noise-reducing curtain 400 is provided with an elastic element so that the noise-reducing curtain 400 can expand and contract with the terrain under the action of elasticity to conform to the ground, further enhancing the sealing effect on the gap at the bottom of the canopy frame 100.

[0048] When the shed 100 needs to be moved, turn the handle to lower the lifting plate 3011 until the roller 3012 contacts the ground. At this time, the bottom of the fixing tooth 202 and the bottom of the shed 100 are both off the ground. Then lock the handle to position the lifting plate 3011, and manually push or pull the shed 100 to the target position. When the shed 100 needs to be fixed after being moved to the target position, turn the handle in the opposite direction to raise the lifting plate 3011. At this time, the shed 100 descends with the fixing tooth 202 until the fixing tooth 202 inserts into the ground, thus fixing the shed 100 in place. At this time, the noise reduction curtain 400 is pressed against the ground to seal the gap between the bottom of the shed 100 and the ground, forming a sound barrier.

[0049] like Figure 1 and Figure 2 As shown, the soundproof door 102 includes a door panel 1021 and a magnetic block 1022. The first end of the door panel 1021 is hinged to the frame 101 to open and close the frame 101. The magnetic block 1022 is installed at the second end of the door panel 1021. Specifically, the second end of the door panel 1021 can be the end away from the hinge end, or it can be the top or bottom end of the door panel 1021. The frame 101 has a magnetic groove 1012 corresponding to the magnetic block 1022. The magnetic block 1022 and the magnetic groove 1012 are precisely aligned to adhere and fit together, ensuring that there is no gap between the door panel 1021 and the frame 101 when closed, resulting in a good sealing effect and further enhancing the sound insulation and noise reduction effect. Moreover, through the cooperation of the magnetic block 1022 and the magnetic groove 1012, the door panel 1021 can automatically close under the action of magnetic force, saving time and effort and effectively improving work efficiency. A handle is installed on the side of the door panel 1021 away from the shelf 101, which facilitates manual operation to control the opening and closing of the door panel 1021.

[0050] like Figure 1 and Figure 2 As shown, a protective frame 103 is also installed on the scaffold 101. The protective frame 103 includes a protective plate 1031 on top of the scaffold 101, a buffer post 1032 fixed to the top of the protective plate 1031, and a protective net 1033 installed on the buffer post 1032. The protective plate 1031 covers the scaffold 101 and is detachably fixed to the scaffold 101, preventing the impact of falling objects on the scaffold 101 and improving safety. The buffer post 1032 and the protective net 1033 buffer external impacts, preventing falling objects from directly impacting the protective plate 1031, ensuring the structural stability of the scaffold 101, and improving the service life of the device. Preferably, the protective plate 1031 and the scaffold 101 are connected by a snap-fit ​​connection, which is convenient for installation and can be reused. Preferably, the buffer post 1032 is a rubber post.

[0051] Preferably, the side of the shed 101 is provided with a transparent observation window, which is a double-layered soundproof glass, so as to facilitate observation of the interior of the shed 100 from the outside.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
