Description

Technical Field

[0001] This utility model relates to the field of windbreak and dust suppression barrier technology, and in particular to a windbreak and dust suppression barrier with a hollow sandwich sound-absorbing structure. Background Technology

[0002] Dust pollution caused by windborne particulate matter during industrial production, mining, construction, and transportation is a widespread and increasingly serious environmental problem. This dust not only affects air quality and harms the health of nearby residents, but also negatively impacts the normal operation and safety of production equipment. To control dust pollution, windbreak and dust suppression barriers are widely used as an important physical means of prevention and control.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Many industrial sites or near major transportation routes suffer from noise pollution in addition to dust problems. Traditional windbreak and dust suppression barriers typically lack effective sound absorption and noise reduction capabilities, failing to achieve multiple environmental governance effects. Faced with strong winds and extreme weather, the structural strength of traditional barriers may be insufficient, easily leading to deformation or damage, affecting their long-term use. Furthermore, the connections between components may be weak, resulting in high maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the traditional windbreak and dust suppression barrier in the prior art usually does not have good sound absorption and noise reduction function. To this end, we propose a windbreak and dust suppression barrier with a hollow sandwich sound absorption structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a windproof and dust-suppressing barrier with a hollow sandwich sound-absorbing structure, comprising: a pair of barrier components and a pair of connecting plates, the pair of barrier components being connected by a pair of connecting plates, the barrier component comprising a pair of fixing plates and a fixing frame, the pair of fixing plates being symmetrically fixedly installed on both sides of the fixing frame, the pair of fixing plates being evenly provided with a plurality of mounting holes at equal intervals, a vent pipe being fixedly installed in a plurality of mounting holes on one fixing plate, the other end of the vent pipe being disposed in a plurality of mounting holes on the other fixing plate, the outer diameter of the vent pipe being consistent with the inner diameter of the mounting hole.

[0006] Preferably, each of the four corners of the pair of fixing plates away from the fixing frame has a first mounting hole, and each of the four corners of the inner sidewall of the fixing frame has a mounting corner block fixedly installed. Each of the four mounting corner blocks has a second mounting hole, and the pair of fixing plates are fixedly connected to the fixing frame by four fastening bolts.

[0007] Preferably, the first mounting hole and the second mounting hole correspond one-to-one, and the fastening bolt corresponds one-to-one with the first mounting hole. The fastening bolt passes through the first mounting hole, the second mounting hole on one corresponding fixing plate, and the first mounting hole on another fixing plate in sequence.

[0008] Preferably, the connecting plate includes a plurality of mounting blocks and a plurality of connecting blocks, the plurality of mounting blocks and the plurality of connecting blocks being arranged alternately, the mounting blocks being fixedly connected to adjacent connecting blocks, and the mounting blocks being fixedly connected to a pair of fixed frames within a pair of barrier assemblies by a plurality of mounting bolts.

[0009] Preferably, each mounting block is provided with a pair of third mounting holes, and each pair of fixed frames in a pair of barrier components is provided with a number of fourth mounting holes on their outer side walls. The number of third mounting holes correspond to the fourth mounting holes on the pair of fixed frames respectively, and the mounting bolts are sequentially threaded into the third mounting holes and the fourth mounting holes.

[0010] Preferably, the width of the mounting block is the same as the width of the connecting block, and the outer edge of the mounting block is abutted against the outer edge of the fixing plate inside the pair of barrier assemblies.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, a hollow sandwich structure consisting of a pair of fixed plates is constructed inside the barrier component, and vent pipes are installed in the sandwich to form a resonant sound-absorbing cavity and a porous sound-absorbing structure. When sound waves enter these vent pipes, multiple reflections and energy dissipation occur inside the vent pipes and between the inner walls of the hollow sandwich, thereby effectively absorbing noise, reducing environmental noise, and overcoming the problem of insufficient noise reduction capability that is common in traditional windbreak and dust suppression barriers.

[0012] In this invention, the ventilation pipe structure of the barrier component not only provides a sound-absorbing channel but also cuts and disperses airflow, reducing wind speed and preventing particulate matter from spreading with the wind, thus improving dust suppression efficiency. The hollow sandwich structure also provides a buffer space for wind and sand, further weakening wind force. By integrating windbreak, dust suppression, and sound absorption / noise reduction functions into one unit, the necessity of setting up a separate noise barrier is reduced, saving material and construction costs and improving site utilization. While improving environmental quality, it also enhances the living comfort of surrounding residents and the work efficiency of production personnel. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a windproof and dust suppression barrier with a hollow sandwich sound-absorbing structure, comprising: a pair of barrier components 1 and a pair of connecting plates 2. The pair of barrier components 1 are connected by a pair of connecting plates 2 to form a complete and extendable barrier structure. This modular design allows the barrier to be extended and combined in length according to actual needs.

[0017] A single barrier component 1 is the functional unit of the entire barrier, comprising a pair of fixing plates 11 and a fixing frame 12. The fixing plates 11 are symmetrically fixed on both sides of the fixing frame 12, forming a hollow sandwich structure. The fixing plates 11 are typically made of materials with certain strength and weather resistance, such as perforated metal plates or fiber-reinforced composite material plates, and their surfaces can be treated with anti-corrosion coatings. The fixing frame 12 provides skeletal support for the barrier component 1 and can be a square or rectangular frame structure, usually welded or spliced ​​from metal profiles (such as I-beams, channel steel, square tubing, etc.), effectively resisting external wind pressure and impact.

[0018] It is worth noting that a number of mounting holes 13 are evenly spaced on each of the pair of fixing plates 11. These mounting holes 13 are the installation positions for the vent pipes 14. A vent pipe 14 is fixedly installed in each of the mounting holes 13 on one fixing plate 11. The other end of the vent pipe 14 is located in one of the mounting holes 13 on the other fixing plate 11. This means that the vent pipe 14 spans between the two fixing plates 11, penetrates the entire hollow sandwich layer, and forms a sound-absorbing channel inside the hollow sandwich layer. To ensure a tight fit and fixation between the vent pipe 14 and the mounting holes 13, the outer diameter of the vent pipe 14 is designed to match the inner diameter of the mounting hole 13, allowing the vent pipe 14 to be tightly fixed within the mounting hole 13. This fixation can be achieved through interference fit, welding, gluing, or other fastening methods.

[0019] Through this structure, the hollow interlayer and the internal venting pipe 14 together form an acoustic resonant cavity and a porous sound-absorbing structure. When external noise (such as wind noise or mechanical noise) enters the barrier, the sound waves enter the mounting holes 13 on the fixed plate 11 and the venting pipe 14, forming multiple reflections and interferences inside the venting pipe 14 and between the inner walls of the hollow interlayer. Part of the sound energy is dissipated by air friction and the sound-absorbing material of the pipe wall (if selected), while the other part is converted into heat energy under the resonance effect, thereby achieving the purpose of sound absorption and noise reduction. At the same time, the through venting pipe 14 also cuts and disperses the oncoming airflow, effectively reducing wind speed, reducing the impact of wind on the equipment or environment behind the barrier, and preventing particulate matter from spreading with the wind, achieving efficient windproof and dust suppression.

[0020] Specifically, each of the four corners of the pair of fixing plates 11 on the side away from the fixing frame 12 has a first mounting hole 15. These first mounting holes 15 are through holes reserved for bolt connection. At the same time, each of the four corners of the inner wall of the fixing frame 12 has a mounting corner block 16 fixedly installed. These mounting corner blocks 16 can be L-shaped or T-shaped metal blocks, which are fixed to the inner side of the fixing frame 12 by welding or other secure methods, providing connection points for the fixing plates 11. Each of the four mounting corner blocks 16 has a second mounting hole 17, which corresponds to the first mounting holes 15 on the fixing plates 11.

[0021] Finally, a pair of fixing plates 11 are fixedly connected to the fixing frame 12 by four fastening bolts 18. In actual installation, the first mounting hole 15 and the second mounting hole 17 are designed to correspond one-to-one, and the fastening bolts 18 correspond one-to-one with the first mounting holes 15. The fastening bolts 18 pass sequentially through the first mounting hole 15, the second mounting hole 17 on one fixing plate 11, and the first mounting hole 15 on the other fixing plate 11. This means that the fastening bolts 18 pass through one fixing plate 11, through the mounting corner block 16, and then through the opposite fixing plate 11, and are then tightened with nuts or threads, firmly connecting the two fixing plates 11 and the fixing frame 12 (through the mounting corner block 16). This connection method not only makes the connection between the fixing plates 11 and the fixing frame 12 tighter and more stable, effectively resisting external stress, but also facilitates subsequent disassembly, maintenance, or replacement, improving the overall maintainability of the barrier.

[0022] Specifically, the connecting plate 2 is not a simple flat structure, but rather comprises several mounting blocks 21 and several connecting blocks 22. The mounting blocks 21 and connecting blocks 22 are staggered, forming an interwoven or spaced composite structure. This staggered arrangement facilitates providing multiple connection points and increases overall structural stability. The mounting blocks 21 are fixedly connected to adjacent connecting blocks 22 to form a complete connecting plate unit. This fixed connection can be achieved through welding, riveting, gluing, or integral molding, etc.

[0023] Mounting block 21 is the key part for achieving the connection. It is fixedly connected to the fixing frame 12 inside and outside a pair of barrier assemblies 1 by a number of mounting bolts 23. This means that the mounting block 21 of the connecting plate 2 is directly fixed to the fixing frame 12 of the barrier assembly 1, rather than to the fixing plate 11. This allows the higher strength of the fixing frame 12 to withstand the connection stress.

[0024] To achieve this connection, each mounting block 21 has a pair of third mounting holes 24. Simultaneously, the outer walls of the pair of fixing frames 12 within the barrier assembly 1, i.e., the side walls of the fixing frames 12 that need to connect to the connecting plate 2, each have several fourth mounting holes 25. These holes are pre-machined with precision. During installation, the pairs of third mounting holes 24 correspond to the fourth mounting holes 25 on the pair of fixing frames 12. Then, mounting bolts 23 are sequentially threaded into the third mounting holes 24 and the fourth mounting holes 25. This means that the mounting bolts 23 pass through the mounting block 21 of the connecting plate 2 and are then directly screwed into or through the threaded holes or nuts on the fixing frames 12 for fixation, thereby firmly connecting the connecting plate 2 to the barrier assembly 1. This threaded installation method makes the connection both robust and reliable, and facilitates rapid on-site assembly and disassembly, improving construction efficiency.

[0025] Furthermore, to achieve a more aesthetically pleasing and tighter connection, the width of the mounting block 21 can be designed to be the same as the width of the connecting block 22. Simultaneously, the outer edge of the mounting block 21 fits against the outer edge of the fixing plate 11 inside the pair of barrier assemblies 1, ensuring that the connecting plate 2 is flush with the surface of the barrier assembly 1 after installation, forming a continuous and seamless appearance. This not only improves aesthetics but also reduces the possibility of wind resistance and dust accumulation.

[0026] In summary, the windproof and dust suppression barrier with a hollow sandwich sound-absorbing structure provided by this invention achieves efficient sound absorption and noise reduction through the ingenious design of the hollow sandwich and the ventilation pipe 14; by optimizing the connection between the fixing plate 11 and the fixing frame 12 and the connection method between the barrier components 1, the structural stability and ease of installation and maintenance are significantly improved, making it an innovative and efficient solution to address complex environmental pollution problems.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
