Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection engineering, and specifically relates to a sound insulation and noise reduction device for factory buildings. Background Technology
[0002] Factory buildings are the core locations for industrial production, characterized by concentrated functions, diverse noise sources (such as the operation of machinery and equipment, and material handling), and complex environments (open spaces and diverse structures that make noise easily reflected and diffused). Sound insulation and noise reduction devices are technical systems specifically designed to reduce noise in or around factory buildings. Their core objectives are to protect workers' hearing health, ensure compliant production (meeting environmental noise restrictions), and optimize the working environment (improving efficiency and reducing the impact on surrounding residents). Noise control is mainly achieved through sound-absorbing materials (using porous structures to convert sound energy into heat energy, such as mineral wool boards and sound-absorbing cotton) and sound insulation structures (using high-density materials to block sound waves, such as soundproof enclosures and soundproof screens).
[0003] Traditional soundproofing devices in existing factories are mostly fixed, large and heavy, making it difficult to move and arrange them flexibly in different locations according to actual needs. When soundproofing work needs to be carried out in different areas of the factory, reinstalling or moving these devices will consume a lot of manpower and time, affecting work efficiency. In addition, the size of the soundproofing devices is usually fixed, making it inconvenient to adjust the soundproofing range appropriately.
[0004] Therefore, existing factory soundproofing devices have certain limitations in terms of their use due to the inconvenience of moving and placing them and the fixed size of the soundproof screens. Utility Model Content
[0005] In order to overcome the problems of existing factory sound insulation devices being inconvenient to move and deploy and having fixed sound barrier sizes, which limit their use, a factory sound insulation and noise reduction device is proposed.
[0006] The technical solution of this utility model is as follows: a factory sound insulation and noise reduction device, including a first limiting platform; it also includes a sound insulation screen and a rotating rod. The upper end of the first limiting platform is fixedly connected to two first limiting strips for subsequent clamping and sliding. Two sound insulation screens are slidably arranged on the first limiting platform. The upper end of the first limiting platform is also fixedly connected to two second limiting strips for limiting the sound insulation screens. The first limiting platform is provided with a second limiting platform. The internal structure of the first limiting platform is the same as that of the second limiting platform. The second limiting platform and the first limiting platform are connected to each other through a handrail and a connecting frame. A limiting sleeve is fixedly connected to one end of the first limiting platform and the second limiting platform that are close to each other. A rotating rod is rotatably arranged inside the limiting sleeve. Two gears are fixedly connected to the outer wall of the rotating rod. Two racks are fixedly connected to one end of the two sound insulation screens that are close to each other. The outer walls of the racks and the outer walls of the gears correspond one-to-one and mesh with each other.
[0007] Preferably, universal wheels for sliding are fixedly connected to the four corners of the lower end of the first limiting platform, two handrails are fixedly connected to the left ends of the first and second limiting platforms, and two connecting frames are fixedly connected to the left and right ends of the first and second limiting platforms.
[0008] Preferably, two first grooves are provided at the ends of the two first limiting strips that are close to each other, and multiple rollers for sliding and clamping the soundproof screen are provided in the first grooves.
[0009] Preferably, a right-angle conversion seat is provided at the upper end of the second limiting platform, and the output shaft of the right-angle conversion seat passes through the second limiting platform and is connected to the rotating rod.
[0010] Preferably, the soundproof barrier is located at the end where the first limiting strip and the second limiting strip are close to each other, and a soundproof chamber is provided inside the soundproof barrier.
[0011] As a preferred option, sound-absorbing cotton is fixed to the ends of the two soundproof barriers that are far apart from each other.
[0012] Preferably, the upper and lower ends of the soundproof barrier are respectively attached to the ends of the second limiting platform and the first limiting platform that are close to each other.
[0013] The beneficial effects of this utility model are: the device can be moved within the factory area by sliding and has a portable synchronous adjustment and unfolding structure, which can facilitate the adjustment of the distance between the two soundproof screens, thus making it applicable to equipment of different sizes. At the same time, the retractable structure reduces the space occupied by the noise reduction device, thereby solving the problem of inconvenient displacement and portable unfolding and adjustment of the noise reduction device in the factory.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5 This utility model provides an embodiment of a factory sound insulation and noise reduction device, including a first limiting platform 1; it also includes a soundproof screen 4 and a rotating rod 301. Two first limiting strips 103 for subsequent clamping and sliding are fixedly connected to the upper end of the first limiting platform 1. Two soundproof screens 4 are slidably arranged on the first limiting platform 1. Two second limiting strips 107 for limiting the soundproof screens 4 are also fixedly connected to the upper end of the first limiting platform 1. A second limiting platform 106 is provided on the first limiting platform 1. The internal structure of the first limiting platform 1 is the same as that of the second limiting platform 106. The second limiting platform 106 and the first limiting platform 1 are interconnected through a handrail 2 and a connecting frame 201. The first limiting platform 1 and the second limiting platform 301 are connected to each other. One end of each of the two sound barriers 4 is fixedly connected to a limiting sleeve 102. A rotating rod 301 is rotatably installed inside the limiting sleeve 102. Two gears 302 are fixedly connected to the outer wall of the rotating rod 301. Two racks 401 are fixedly connected to the one end of each of the two sound barriers 4. The outer walls of the racks 401 and the outer walls of the gears 302 correspond to each other and mesh with each other. The device can be moved within the factory area by sliding and has a portable synchronous adjustment and unfolding structure, which can easily adjust the distance between the two sound barriers 4. This makes it suitable for equipment of different sizes. At the same time, the retractable structure reduces the space occupied by the noise reduction device, thus solving the problem of inconvenient displacement and portable unfolding and adjustment of the noise reduction device in the factory.
[0022] Please see Figures 1-3In this embodiment, universal wheels 101 for sliding are fixedly connected to the four corners of the lower end of the first limiting platform 1. Two handrails 2 are fixedly connected to the left ends of the first limiting platform 1 and the second limiting platform 106. Two connecting frames 201 are fixedly connected to the left and right ends of the first limiting platform 1 and the second limiting platform 106. The universal wheels 101 can improve the mobility and portability of the device and adapt to the sound insulation requirements of different locations in the factory. Two first grooves 104 are opened at the ends of the two first limiting bars 103 that are close to each other. Multiple rollers 105 for sliding and clamping the sound insulation screen 4 are provided in the first grooves 104. The rollers 105 reduce the friction when the sound insulation screen 4 slides, improve the operability of the device during adjustment, and increase the service life.
[0023] Please see Figures 4-5 In this embodiment, a right-angle conversion seat 3 is provided at the upper end of the second limiting platform 106. The output shaft of the right-angle conversion seat 3 passes through the second limiting platform 106 and is connected to the rotating rod 301. The soundproof screen 4 is located at the end of the first limiting strip 103 and the second limiting strip 107 that are close to each other. A soundproof chamber 402 is provided inside the soundproof screen 4. Soundproof cotton 403 is fixed to the ends of the two soundproof screens 4 that are far apart from each other. The upper and lower ends of the soundproof screen 4 are respectively attached to the ends of the second limiting platform 106 and the first limiting platform 1 that are close to each other.
[0024] First, support and push the handrail 2 to place the device at the desired location. Then, use a handheld electric screwdriver to connect its output end to the input end on the right-angle converter 3, thereby driving the gear 302 on the rotating rod 301 to rotate. This causes the two soundproof screens 4 to be limited by components on the first limiting platform 1 and the second limiting platform 106. Next, through the meshing of the gear 302 and the rack 401, the two soundproof screens 4 unfold under the rotation of the gear 302. Then, through the soundproofing chamber 402 and the soundproofing cotton 403 on the soundproof screens 4, the soundproofing material is further expanded. After the engineering components are opened, the noise is eliminated. Through the connection between the rack 401 and the gear 302, the unfolding range between the two soundproof screens 4 can be adjusted. The soundproof chamber 402 reflects, absorbs and dissipates the noise. Combined with the soundproof cotton 403, it forms a good sound absorption effect and improves the noise reduction intensity of the device. The rollers 105 on the second limit bar 107 and the first limit bar 103 limit the soundproof screen 4, which can reduce the friction of the soundproof screen 4 during the sliding process, so that the soundproof screen 4 can unfold smoothly, improving the operability and service life of the device.
