Abstract
Description
Technical Field
[0001] This utility model relates to the field of sound absorption and noise reduction technology, and in particular to a sound barrier with protective function. Background Technology
[0002] The working principle of a sound barrier is based on the reflection, absorption, and diffraction of sound waves. When a sound wave encounters a sound barrier, some of the sound waves are reflected on the barrier surface, some are absorbed by the barrier material and converted into heat or other forms of energy, and some diffract over the top of the barrier to reach the receiving point. With a barrier, the sound waves travel a longer distance than when they travel directly without a barrier, thus resulting in a certain degree of attenuation. The design goal of a sound barrier is to make the receiving point fall within the sound shadow zone by rationally designing the height, length, and material of the barrier, thereby achieving a noise reduction effect.
[0003] To this end, Chinese patent application number CN207739168U discloses a sound barrier, comprising several barrier components. Adjacent barrier components are fixedly connected by columns. Each barrier component includes a lower sound-absorbing body, a middle sound-insulating body, and an upper sound-insulating body. The sound-insulating body includes several middle sound-insulating bodies evenly distributed vertically. Both the middle and upper sound-insulating bodies include sound-absorbing cotton and a sound-insulating plate covering the outside of the sound-absorbing cotton. Each column includes several column components evenly distributed vertically. Each column component includes a pole and a connecting plate fixedly connected to the pole. The connecting plate is fixedly connected to the barrier components. The upper sound-insulating body includes a lower vertical section and an upper inclined section, with the inclined section tilted away from the column. The overall height of the sound barrier can be adjusted by adjusting the number of sound-insulating components and column components; the sound insulation effect is good.
[0004] The aforementioned sound barrier proposes to adjust the overall height of the sound barrier by adjusting the number of sound insulation components and column components. However, if the sound barrier fails to provide protection, traffic noise will directly spread to residential areas, resulting in a significant increase in indoor and outdoor noise levels. Utility Model Content
[0005] The purpose of this invention is to provide a sound barrier with protective functions to solve the shortcomings of existing sound barriers that cannot provide protection.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sound barrier with protective function, including a base column;
[0007] The top of the base column is equipped with an installation structure, and the top of the installation structure is equipped with a sound insulation structure.
[0008] The sound insulation structure includes a column set at the top of the installation structure, a triangular block installed at the bottom of the column, a slot opened on one side of the column, and a locking block set in the slot;
[0009] A noise reduction plate is provided on one side of the card block, a baffle is installed at one end of the noise reduction plate, and an anti-corrosion layer is installed at the other end of the noise reduction plate.
[0010] In use, the noise reduction panel is equipped with a sound insulation structure and slots at both ends. The slots can extend into the interior of the column and the noise reduction panel, allowing them to engage and improving installation efficiency. A spoiler is installed at one end of the noise reduction panel. By changing the airflow direction, the spoiler guides the air to flow more smoothly over the surface of the noise reduction panel. The spoiler's airflow smoothing effect reduces noise reflection and diffraction around the sound barrier.
[0011] Furthermore, the card block is T-shaped, and slots are provided on the surfaces of both ends of the noise reduction plate to facilitate engagement between the noise reduction plate and the card block.
[0012] Furthermore, one end of the card block extends into the interior of the noise reduction plate, and the other end of the card block extends into the interior of the card slot, thereby enhancing the stability of the card block and the noise reduction plate.
[0013] Furthermore, the spoiler is provided in multiple sets, and the spoiler is arranged at equal intervals to facilitate better spoiler performance.
[0014] Furthermore, the inner diameter of the slot is larger than the outer diameter of the block, and the block and the slot form an engaging structure to reduce wear on the block.
[0015] Furthermore, the mounting structure includes a positioning block disposed at the top of the base column, and positioning holes are provided on the surfaces at both ends of the positioning block. Screws are disposed inside the positioning holes to improve the stability of the positioning block.
[0016] Furthermore, the positioning hole has an internal thread, and the screw has an external thread. The positioning hole and the screw form a threaded connection, which facilitates convenient screw installation.
[0017] This utility model provides a sound barrier with protective functions, the advantages of which are: by setting up the sound barrier, a protective effect can be achieved, making its effect better, and the sound insulation structure further enhances its protective effect.
[0018] By incorporating a sound insulation structure, the noise reduction panel features slots at both ends, allowing the locking blocks to extend into the columns and panels, thus securing them together and improving installation efficiency. The panel is made of rock wool, a porous material that absorbs some of the sound energy through friction caused by flow resistance, further enhancing noise reduction. To further improve noise reduction, a baffle plate is installed at one end, guiding airflow across the panel's surface and reducing noise reflection and diffraction around the sound barrier, resulting in more significant noise reduction within specific frequency bands. Finally, an anti-corrosion layer made of epoxy resin is applied to the other end. This dense epoxy resin coating effectively prevents the penetration of water, oxygen, and corrosive ions, protecting the noise reduction panel from external environmental influences and providing long-term stable protection.
[0019] By incorporating an installation structure, the stability of the base column is improved when providing sound barrier protection. This is because the positioning block surface has positioning holes with internal threads inside and external threads outside the screws. The positioning holes and screws form a threaded connection. By applying appropriate torque, the preload of the threaded connection can be controlled to prevent loosening or overloading. Attached Figure Description

[0026] 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.
[0027] Please see Figures 1-5 As shown, one embodiment of this utility model is a sound barrier with protective function, including a base column 1.
[0028] A mounting structure 2 is installed at the top of the base column 1. The mounting structure 2 includes a positioning block 201 set at the top of the base column 1. Positioning holes 202 are opened on both ends of the positioning block 201. The positioning holes 202 have internal threads, and the screws 203 have external threads. The positioning holes 202 and the screws 203 form a threaded connection. The screws 203 are set inside the positioning holes 202. A sound insulation structure 3 is installed at the top of the mounting structure 2.
[0029] Please see Figures 1-2 As shown, the stability of the base column 1 is improved by setting the mounting structure 2. The positioning block 201 has a positioning hole 202 on its surface. The positioning hole 202 has an internal thread, and the screw 203 has an external thread. The positioning hole 202 and the screw 203 form a threaded connection. By applying an appropriate torque, the preload of the threaded connection can be controlled to prevent the connection from becoming loose or overloaded.
[0030] The sound insulation structure 3 includes a column 301 set at the top of the installation structure 2. A triangular block 302 is installed at the bottom of the column 301. A slot 303 is opened on one side of the column 301. The inner diameter of the slot 303 is larger than the outer diameter of the block 304. The block 304 and the slot 303 form a locking structure.
[0031] A card block 304 is provided in the card slot 303. One end of the card block 304 extends into the noise reduction plate 306, and the other end of the card block 304 extends into the card slot 303. The card block 304 is T-shaped. Card slots 303 are provided on the surfaces of both ends of the noise reduction plate 306.
[0032] A noise reduction plate 306 is provided on one side of the card block 304. A spoiler 305 is installed at one end of the noise reduction plate 306. Multiple sets of spoilers 305 are provided and are arranged at equal intervals. An anti-corrosion layer 307 is installed at the other end of the noise reduction plate 306.
[0033] Please see Figure 1 and Figures 3-5As shown, slots 303 are provided at both ends of the surface of the noise reduction plate 306, and locking blocks 304 can extend into the interior of the column 301 and the noise reduction plate 306, thereby locking the column 301 and the noise reduction plate 306 together, improving installation efficiency. Because the noise reduction plate 306 is made of rock wool board, which has a porous structure, when sound waves pass through, the flow resistance generates friction, causing some of the sound energy to be absorbed by the fibers, blocking the transmission of sound waves. To improve the noise reduction effect, a baffle 305 is provided at one end of the noise reduction plate 306. The baffle 305 guides the airflow by changing the airflow direction. Air flows more smoothly over the surface of the noise reduction panel 306, reducing airflow turbulence and eddy formation. The airflow smoothing effect of the spoiler 305 reduces noise reflection and diffraction around the sound barrier. By optimizing the sound wave propagation path, the sound barrier can achieve a more significant noise reduction effect in a specific frequency band. An anti-corrosion layer 307 is set on the other end of the noise reduction panel 306. Because the anti-corrosion layer 307 is made of epoxy resin coating, the epoxy resin coating is dense and can effectively prevent the penetration of water, oxygen and corrosive ions, protecting the noise reduction panel 306 from the influence of the external environment and providing long-term stable protection for the noise reduction panel 306.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
