Description

Technical Field

[0001] This utility model relates to the field of noise control technology, and in particular to a soundproof barrier for industrial production noise control. Background Technology

[0002] Industrial production activities often generate a lot of noise, which can easily affect the physical and mental health of employees. In order to minimize employees' exposure to noise, sound is usually isolated and noise is reduced by using wooden boards, metal boards, and sound insulation boards. However, existing sound insulation devices are inconvenient to install, and if the equipment is damaged, the entire equipment needs to be replaced, resulting in unnecessary economic losses.

[0003] Existing technology CN213418713U discloses a sound barrier for noise control in coal washing plants, specifically relating to the field of noise control technology. It includes a U-shaped frame, a movable frame fixedly connected to the bottom of the U-shaped frame, a support frame fixedly connected to the outer wall of the movable frame, a sliding groove inside the U-shaped frame, a sound-insulating panel inside the U-shaped frame, a slider fixedly connected to the outer wall of the sound-insulating panel, an insert plate fixedly connected to the bottom of the sound-insulating panel, a slot inside the insert plate, a limiting groove on the inner wall of the slot, and a first groove on the top of the sound-insulating panel. This invention strengthens the connection between multiple sets of sound-insulating panels by engaging the limiting groove on the inner wall of the slot with the spring plate on the outer wall of the first insert plate. In daily use, when the sound-insulating panels are damaged by impacts from foreign objects, replacing the individual sound-insulating panels extends the overall service life of the equipment, avoiding the need to replace the entire unit when the equipment is damaged, as is common with sound-insulating panels on the market, thus preventing unnecessary economic losses.

[0004] However, in actual production and use, the mobile frame will extend out of the sound barrier after the equipment is installed and positioned, which can easily cause people to trip and fall when passing by, resulting in poor safety during use. Utility Model Content

[0005] The purpose of this invention is to provide a soundproof barrier for industrial noise control, which aims to improve safety during noise control applications.

[0006] To achieve the above objectives, this utility model provides a sound barrier for industrial production noise control, including a fixed frame, a first mounting cavity and a second mounting cavity respectively provided on the bottom of both sides of the fixed frame, a sound insulation board installed in the fixed frame, and a moving mechanism.

[0007] The moving mechanism includes a threaded sleeve, a screw, a mounting plate, universal silent wheels, and a noise reduction device. The threaded sleeve is fixedly connected to the fixed frame and is located in the second mounting cavity near the first mounting cavity. The screw is threadedly connected to the threaded sleeve and passes through the threaded sleeve, with its top stepped end being an external hexagonal prism. The mounting plate is integrally formed with the screw and is located at the bottom of the screw. The diameter of the mounting plate is smaller than the width of the rectangular through cavity at the bottom of the first mounting cavity. The universal silent wheels are fixed to the bottom of the mounting plate, and the noise reduction device is disposed on the front and rear sides of the fixed frame.

[0008] A limiting threaded ring is screwed onto the screw, and the limiting threaded ring can abut against the top end face of the threaded sleeve.

[0009] The moving mechanism further includes a turntable, which is detachably connected to the screw and located at the top of the screw.

[0010] The noise reduction device includes a front noise reduction plate and a rear noise reduction plate. The front noise reduction plate is fixed to the front side of the fixed frame, and the rear noise reduction plate is fixed to the rear side of the fixed frame.

[0011] The sound barrier for industrial production noise control also includes a protection mechanism, which includes an upper sealing plate and a lower sealing plate. The upper sealing plate is fixed on both sides of the fixed frame and located outside the second mounting cavity; the lower sealing plate is fixed on both sides of the fixed frame and located outside the first mounting cavity.

[0012] This utility model discloses a soundproof barrier for industrial production noise control. In use, the soundproofing panel provides deep sound insulation, while the silencing device provides initial silencing, improving noise control effectiveness. When moving the equipment, rotating the screw drives the mounting plate downwards until the universal silent wheels touch the ground, lifting the bottom of the fixing frame off the ground, allowing the equipment to move. To fix the equipment with bolts, first rotating the screw drives the mounting plate upwards, retracting the universal silent wheels into the first mounting cavity. Then, the mounting holes at the bottom of the fixing frame are used with bolts for installation and fixation. After installation, the moving mechanism is retracted, preventing tripping hazards and improving safety during noise control. Attached Figure Description

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a sound barrier for industrial noise control. Figure 2 This is a structural schematic diagram of the screw 106. This utility model provides a soundproof barrier for industrial noise control: it includes a fixed frame 101, a soundproof panel 104, and a moving mechanism. The moving mechanism includes a threaded sleeve 105, a screw 106, a mounting plate 107, universal silent wheels 108, and a silencing device. The silencing device includes a front silencing plate 111 and a rear silencing plate 112. The aforementioned solution improves safety during noise control applications. It is understood that the aforementioned solution enhances safety during use.

[0021] In this embodiment, a first mounting cavity 102 and a second mounting cavity 103 are respectively provided on the bottom of both sides of the fixed frame 101, and a sound insulation plate 104 is installed inside the fixed frame 101. The sound insulation plate 104 is used for sound insulation treatment, and four mounting ears are provided on the front side of the sound insulation plate 104 for easy fixing to the fixed frame 101 with bolts. After the bolts are installed, the head end face will be lower than the mounting stepped groove of the fixed frame 101.

[0022] The threaded sleeve 105 is fixedly connected to the fixed frame 101 and is located in the second mounting cavity 103 near the first mounting cavity 102. The screw 106 is threadedly connected to the threaded sleeve 105 and passes through the threaded sleeve 105. The small end of the top stepped end of the screw 106 is an external hexagonal prism. The mounting plate 107 is integrally formed with the screw 106 and is located at the bottom of the screw 106. The diameter of the mounting plate 107 is smaller than the width of the rectangular through cavity at the bottom of the first mounting cavity 102. The universal silent wheel 108 is fixed to the bottom of the mounting plate 107. The noise reduction device is arranged on the front and rear sides of the fixed frame 101. The threaded sleeve 105 has a T-shaped cross-section and is fixed by bolts. The screw 106 is threadedly engaged with the threaded sleeve 105. The mounting plate 107 is integrally provided at the bottom of the screw 106. The universal silent wheel 108 is provided at the bottom of the mounting plate 107. The diameter of the mounting plate 107 is smaller than the width of the rectangular cavity at the bottom of the first mounting cavity 102, so as to facilitate the passage through the rectangular cavity. The silencing device is used for primary noise treatment, thereby forming a multi-stage silencing structure, which helps to improve the noise treatment effect.

[0023] Secondly, a limiting screw ring 109 is screwed onto the screw 106, and the limiting screw ring 109 can abut against the top end face of the threaded sleeve 105. After the limiting screw ring 109 rotates, when it abuts against the top end face of the threaded sleeve 105, the screw 106 can be locked to prevent loosening.

[0024] Then, the turntable 110 is detachably connected to the screw 106 and is located on top of the screw 106. The outer hexagonal portion on the top of the screw 106 can be directly engaged with a wrench to rotate the screw 106. Furthermore, the turntable 110 is provided with a through inner hexagonal hole, which can be directly installed on the top of the screw 106. Compared with rotating with a wrench, rotating the screw 106 through the turntable 110 is more convenient and faster. The turntable 110 can be removed and stored after the equipment is installed.

[0025] Finally, the front muffler 111 is fixed to the front side of the fixed frame 101; the rear muffler 112 is fixed to the rear side of the fixed frame 101. The front muffler 111 is fixed to the front side of the fixed frame 101 by bolts, and the rear muffler 112 is fixed to the rear side of the fixed frame 101 by bolts. After the front muffler 111 and the rear muffler 112 are fixed, the sound insulation plate 104 is located between them.

[0026] When using this utility model for noise control, it can improve safety. Firstly, the front and rear sound-absorbing plates 111 and 112 perform initial noise reduction. Further, the sound insulation plate 104 performs deep sound insulation, thus improving the noise control effect. Then, when moving the equipment, the turntable 110 rotates the screw 106, causing the mounting plate 107 to descend until the universal silent wheels 108 touch the ground, lifting the bottom of the fixing frame 101 off the ground, allowing the equipment to move. Then, when fixing the equipment with bolts, the turntable 110 rotates the screw 106, causing the mounting plate 107 to rise, thus retracting the universal silent wheels 108 into the first mounting cavity 102. Finally, the mounting holes at the bottom of the fixing frame 101 are used to install and fix the equipment. After installation, the moving mechanism is retracted, preventing tripping when people pass by, thereby improving safety during noise control.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of a sound barrier for industrial production noise control. Based on the first embodiment, this utility model provides a sound barrier for industrial production noise control. The sound barrier for industrial production noise control also includes a protective mechanism, which includes an upper sealing plate 201 and a lower sealing plate 202.

[0029] The upper sealing plate 201 is fixed to both sides of the fixed frame 101 and located outside the second mounting cavity 103; the lower sealing plate 202 is fixed to both sides of the fixed frame 101 and located outside the first mounting cavity 102. The upper sealing plate 201 is fixed to the stepped groove outside the second mounting cavity 103 by bolts, and the lower sealing plate 202 is fixed to the stepped groove outside the first mounting cavity 102 by bolts.

[0030] In this embodiment, the working components inside the first mounting cavity 102 and the second mounting cavity 103 can be protected by setting the upper sealing plate 201 and the lower sealing plate 202.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
