[0018] like Figures 1 to 5As shown, a construction noise reduction device includes: a fixed frame 1, which is U-shaped and has an installation groove 101 inside, through which a noise reduction plate 3 is slidably connected; and a control mechanism, which is located inside the fixed frame 1 and is used to control the noise reduction plate 3. The control mechanism includes a control component 2 and a limiting component 4. The limiting component 4 is located inside the fixed frame 1 and is used to limit the noise reduction plate 3. The control component 2 is located inside the fixed frame 1 and is used to control the limiting component 4. The control component 2 works with the limiting component 4 to install and remove the noise reduction plate 3. Specifically, during use, the noise reduction plate 3 is added from the bottom of the fixed frame 1 into the installation groove 101. During the addition process, the noise reduction plate 3 is limited by the cooperation of the control component 2 and the limiting component 4 to ensure the stability of the noise reduction plate 3 during use. An installation plate is also provided on the outside of the fixed frame 1. The installation plate can work with ground nails to limit the fixed frame 1 during use to ensure the stability of the fixed frame 1 during use.

[0019] like Figures 1 to 5 As shown, the outer side of the fixed frame 1 is also provided with a through groove and a guide groove 103, and the through groove is connected to the mounting groove 101. A pressure plate 102 is provided inside the through groove, and a rotating groove 104 is provided inside the fixed frame 1. There are multiple rotating grooves 104. Specifically, during use, the pressure plate 102 blocks the noise reduction plate 3 inside the mounting groove 101 to prevent the noise reduction plate 3 from sliding out of the through groove. The pressure plate 102 and the fixed frame 1 can be connected by a buckle or bolt to ensure the stability of the pressure plate 102 during use. The rotating groove 104 can provide support for the limiting member 4 during use, ensuring that the limiting member 4 can stably support the noise reduction plate 3 during use.

[0020] like Figures 1 to 5 As shown, there are multiple noise reduction panels 3, each with a sound-absorbing layer 301 inside. The sidewalls of the noise reduction panels 3 have grooves 302. Specifically, during use, the noise reduction panels 3 work with the sound-absorbing layers 301 to absorb the noise generated during construction. The sound-absorbing layer 301 can be made of rock wool or glass wool, and the noise reduction panels 3 can be made of aluminum alloy or stainless steel. The noise reduction panels 3 limit the position of the sound-absorbing layer 301 while protecting it, ensuring the stability of the sound-absorbing layer 301 during use. Multiple through holes are also provided on the outside of the noise reduction panels 3 to ensure that sound waves can enter the interior of the noise reduction panels 3 during use.

[0021] like Figures 1 to 5As shown, the limiting component 4 includes a rotating shaft 404, and there are multiple rotating shafts 404, with each rotating shaft 404 corresponding to a rotating groove 104. The rotating shaft 404 is connected to the fixed frame 1. A swing rod 403 is rotatably connected to the outside of the rotating shaft 404. A limiting block 401 is provided at the end of the swing rod 403 relative to the noise reduction plate 3. The limiting block 401 and the counterweight block 402 swing inside the rotating groove 104. Specifically, when installing the noise reduction plate 3, the noise reduction plate 3 is first placed inside the mounting groove 101 through the through groove, and then the noise reduction plate 3 inside the mounting groove 101 is controlled to move upward. During the movement of the noise reduction plate 3, the limiting block 401 and the swing rod 403 are first pushed to rotate around the rotating shaft 404. When the groove 302 moves to the top of the limiting block 401, the limiting block 401 loses the support of the noise reduction plate 3 and rotates downward under the action of gravity. This, together with the groove 302, provides support for the noise reduction plate 3, preventing the noise reduction plate 3 from sliding down during use. It also facilitates the subsequent installation of the noise reduction plate 3. After the noise reduction plate 3 is installed, the pressure plate 102 and the through groove cooperate to block the noise reduction plate 3, ensuring the stability of the noise reduction plate 3 during use.

[0022] like Figures 1 to 5 As shown, the control component 2 includes a connecting plate 201, which slides inside the fixed frame 1. A sliding plate 202 and a connecting rod 203 are respectively provided on the outer side of the connecting plate 201. Multiple sliding plates 202 slide inside the rotating groove 104, and each sliding plate 202 corresponds to a swing rod 403. The connecting rod 203 slides inside the guide groove 103, and a nut 204 is threaded onto the outer side of the connecting rod 203. Specifically, when the noise reduction plate 3 needs to be disassembled, the connecting plate 201 is first moved downwards by the connecting rod 203. Simultaneously, the sliding plate 202 pushes the swing rod 403 and the limiting block 401 to rotate, thus releasing the limiting block 401 from the noise reduction plate 3, facilitating the sequential removal of the noise reduction plate 3 from the through groove. The position of the connecting plate 201 is adjusted by controlling the contact and separation of the nut 204 with the fixed frame 1, ensuring the stability of the connecting plate 201 during use.

[0023] like Figures 1 to 5 As shown, the limiting block 401 has an installation hole inside, and a counterweight 402 is provided inside the installation hole. Specifically, the counterweight 402 is located on one side of the limiting block 401. The counterweight 402 and the installation hole can be connected by a slot or an interference fit, thereby ensuring that the limiting block 401 stably limits the noise reduction plate 3 during use.

[0024] like Figures 1 to 5As shown, the working state of this construction noise reduction device is as follows: it includes a fixed frame 1, which is U-shaped, and an installation groove 101 is provided inside the fixed frame 1. A noise reduction plate 3 is slidably connected inside the installation groove 101. A control mechanism is set inside the fixed frame 1 and is used to control the noise reduction plate 3. The control mechanism includes a control component 2 and a limiting component 4. The limiting component 4 is set inside the fixed frame 1 and is used to limit the noise reduction plate 3. The control component 2 is set inside the fixed frame 1 and is used to control the limiting component 4. The control component 2 cooperates with the limiting component 4 to assemble and disassemble the noise reduction plate 3.

[0025] In summary, during the use of this utility model, the fixing frame 1 is first installed to ensure its stability. Then, multiple noise-reducing plates 3 are added sequentially from the through slot into the mounting slot 101. During the addition of the noise-reducing plates 3, the limiting block 401 and the groove 302 cooperate to limit the position of the noise-reducing plates 3, ensuring their stability during use. When it is necessary to disassemble the noise-reducing plates 3, the connecting rod 203 controls the connecting plate 201 and the sliding plate 202 to move downwards. During the movement, the sliding plate 202... The swing rod 403 and the limiting block 401 are controlled to swing, so that the limiting block 401 slides out from the groove 302, thereby releasing the limitation on the noise reduction plate 3, and allowing the noise reduction plate 3 to be taken out sequentially through the through groove. This utility model realizes the cooperation of the fixed frame 1, the mounting groove 101, the rotating groove 104, the limiting block 401, the swing rod 403 and the rotating shaft 404 through the setting of the fixed frame 1 and the limiting member 4, so as to install the noise reduction plate 3 from bottom to top, avoiding the need for operators to climb to the top of the support frame for high-altitude transportation operations, and eliminating the installation hazards during the transportation process.
