Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically a closed sound barrier. Background Technology

[0002] Enclosed sound barriers are an effective noise control facility. In order to improve the sound shielding effect, enclosed shielding devices are used to shield noise sources and reduce noise interference to the external environment.

[0003] Conventional enclosed sound barriers use sealed enclosures to isolate noise, with sound-absorbing panels installed inside. These panels have sound-absorbing holes of different shapes that absorb noise. However, enclosed sound barriers are susceptible to damage from impacts during use. When a section of the enclosed sound barrier is damaged, the entire inner wall needs to be replaced, increasing repair costs. Therefore, we propose an enclosed sound barrier design. Utility Model Content

[0004] To address the shortcomings of existing enclosed sound barriers, this utility model provides an enclosed sound barrier with horizontal panels fixed inside a sealed enclosure by mounting gaskets. When a horizontal panel in a certain part is damaged, the mounting gasket in that part can be removed to replace the horizontal panel, thus reducing maintenance costs and solving the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A closed sound barrier includes a base 1. Slide grooves 2 are formed inside both sides of the base 1. A first lead screw 3 is installed inside the slide grooves 2. Rotating the first lead screw 3 adjusts the position of a mounting plate 4. The mounting plate 4 is threaded onto the outside of the first lead screw 3 and engages with the inside of a sealed box 5, ensuring the stability of the sealed box 5 when it is positioned at the upper end of the mounting plate 4. Two sets of sealed boxes 5 are placed on the upper part of the base 1. An auxiliary cover plate 6 is sleeved on the outside of the connection between the two sets of sealed boxes 5. The auxiliary cover plate 6 is sleeved on both sides of the outside. A pressure plate 8 moves the auxiliary cover plate 6 to be confined to the upper part of the sealed box 5. Pressure plates 8 are installed on both sides of the auxiliary cover plate 6. A first sound-absorbing plate 10 and a second sound-absorbing plate 11 for noise absorption are installed inside the sealed box 5.

[0023] Please see Figure 4 The mounting plate 4 is installed inside the sealed box 5. The sealed box 5 and the auxiliary cover plate 6 are attached to the upper end of the base 1. By installing the mounting plate 4 on the upper part of the base 1, after the sealed box 5 is installed on the upper part of the base 1, the first lead screw 3 is rotated. The first lead screw 3 pushes the mounting plate 4 to move outward. The mounting plate 4 is used to lock and limit the position of the inner side of the sealed box 5, ensuring that the inner side of the sealed box 5 remains stable when it is positioned.

[0024] Please see Figure 4 The first lead screw 3 is installed inside the base 1. Reverse threaded grooves are opened on both sides of the first lead screw 3, and a set of mounting plates 4 are threadedly sleeved on the outer sides of both sides of the first lead screw 3. The first lead screw 3 is installed inside the base 1. When the first lead screw 3 is rotated, the first lead screw 3 and the two sets of mounting plates 4 move synchronously with the threaded movement, controlling the mounting plates 4 to move inward or outward synchronously, ensuring the stability and flexibility of the mounting plates 4 when moving and adjusting.

[0025] Please see Figure 1A limiting baffle 7 is fixedly connected to the outside of the sealed box 5 to limit the auxiliary cover plate 6. The limiting baffle 7 is kept flush with the outside of the sealed box 5. When the size of the equipment needs to be adjusted, the distance between the two sets of sealed boxes 5 is controlled. The auxiliary cover plate 6 is sleeved on the outside of the two sets of sealed boxes 5. The auxiliary cover plate 6 seals the outside of the connection. At the same time, the limiting baffle 7 is installed on the outside of the sealed box 5. The limiting baffle 7 locks and limits the position of the auxiliary cover plate 6 on both sides to ensure that the auxiliary cover plate 6 is positioned stably when it is sleeved on the outside of the sealed box 5.

[0026] Please see Figure 5 The structure of the first sound-absorbing plate 10 and the second sound-absorbing plate 11 includes a horizontal plate 101. A mounting gasket 103 is fixedly connected to the side of the horizontal plate 101. The mounting gasket 103 is fixed to the inner wall of the sealed box 5 by bolts. The horizontal plate 101 is arranged in an inclined state. The horizontal plate 101 has sound-absorbing holes 102 inside. The first sound-absorbing plate 10 and the second sound-absorbing plate 11 are attached to the inner side of the sealed box 5. The first sound-absorbing plate 10 includes the horizontal plate 101 and the mounting gasket 103. The mounting gasket 103 can drive the horizontal plate 101 to be assembled, ensuring the convenience of installation and disassembly of the horizontal plate 101 structure during use. At the same time, the sound-absorbing holes 102 inside the horizontal plate 101 absorb the noise generated inside the sealed box 5 when the equipment is in use, thereby reducing the noise.

[0027] Please see Figure 1 The sealed box 5 is equipped with a second screw 9 that controls the left and right movement of the pressure plate 8. The pressure plate 8 is attached to the outside of the auxiliary cover plate 6. After the auxiliary cover plate 6 is sleeved on the outside of the two sets of sealed boxes 5, the second screw 9 is rotated, and the pressure plate 8 is pushed to move inward. That is, the pressure plate 8 can press and limit the position of the auxiliary cover plate 6 outside the sealed box 5. In other words, during the adjustment of the width of the sealed box 5, the mounting plate 4 and the pressure plate 8 are fixed by squeezing from the inside and outside respectively, so as to improve the stability of the equipment during assembly.

[0028] Please see Figure 2 The base 1, the sealed box 5, and the auxiliary cover plate 6 form a sealed box. The device to be tested is placed inside the sealed box. The base 1, the sealed box 5, and the auxiliary cover plate 6 are assembled into a whole. That is, the base 1, the sealed box 5, and the auxiliary cover plate 6 can seal and shield the sound generated inside, reducing the phenomenon of sound diffusion.

[0029] Working principle: During use, depending on the required size of the sealed shielding equipment, the first lead screw 3 is rotated. The first lead screw 3 drives the mounting plate 4 to adjust its position on the upper part of the base 1. At the same time, after the sealed box 5 is installed on the upper part of the base 1, the mounting plate 4 is snapped into the lower end of the sealed box 5 to ensure the stability of the sealed box 5 when it is positioned on the upper part of the base 1. Simultaneously, the second lead screw 9 is rotated, and the second lead screw 9 pushes the pressure plate 8 to adjust its position to ensure the stability of the auxiliary cover plate 6 when it is positioned on the upper part of the sealed box 5. Thus, the entire equipment forms a sealed box. The first sound-absorbing plate 10 and the second sound-absorbing plate 11 are installed inside the sealed box 5. The first sound-absorbing plate 10 has sound-absorbing holes 102 inside, which effectively absorb noise. The first sound-absorbing plate 10 and the second sound-absorbing plate 11 can be replaced as needed during use, which improves the service life of the equipment and the convenience of maintenance.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
