Description

Technical Field

[0001] This utility model relates to the technical field of noise blocking devices, specifically a noise blocking device for urban road traffic. Background Technology

[0002] Traffic noise refers to the sounds produced by vehicles during operation that interfere with people's normal life and work. It mainly refers to the noise generated by motor vehicles traveling on main traffic lines in cities. It is an unstable noise, and the sound level changes with time and other factors. This noise can cause noise pollution to surrounding residential areas, so noise blocking devices are needed to reduce noise.

[0003] In practical applications, existing noise-blocking devices have relatively complete structures and functions, and can meet basic usage requirements. However, the following problems still exist:

[0004] In practical use, sound barriers are often used for noise reduction. However, these barriers are usually welded and fixed, making replacement inconvenient once damaged. Furthermore, the barriers are lined with sound-absorbing foam, which is often fixed to the inner wall of the barrier with glue, affecting the recycling of these materials. Moreover, the sound-absorbing foam ages over time, significantly reducing the noise reduction effect of the barrier, which is also very inconvenient.

[0005] Therefore, this utility model provides a device for blocking traffic noise on urban roads. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an urban road traffic noise blocking device to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a noise blocking device for urban road traffic, including a mounting base, a sound-insulating shielding structure on the top of the mounting base, the sound-insulating shielding structure including a rectangular insert frame, the bottom of the rectangular insert frame being fixedly connected to the top of the mounting base, a rectangular ring clip frame being inserted into the inner wall of the rectangular insert frame, a connecting plate being fixedly connected to the top of the rectangular ring clip frame, and a noise-reducing sponge board being fixedly connected to the inner wall of the rectangular ring clip frame; symmetrical resonance noise reduction structures are arranged on both sides of the connecting plate, the resonance noise reduction structure including a rectangular clip frame, one side of the rectangular clip frame being fixedly connected to one side of the connecting plate.

[0008] In a preferred embodiment, a first insertion hole is provided on one side of the rectangular insertion frame, and a second insertion hole is provided on one side of the rectangular ring frame. A threaded insertion rod is inserted into the inner wall of the first and second insertion holes, and a fixing nut is threaded to one end of the threaded insertion rod.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded insertion rod, it can be inserted into the inner wall of the first insertion hole and the second insertion hole. At this time, the rectangular insertion frame and the rectangular ring frame can be fixed with the fixing nut, and then the noise reduction sponge board and other components can be disassembled for easy replacement or recycling after aging.

[0010] In a preferred embodiment, a rectangular slot is provided on one side of the mounting base, and a rectangular slot block is fixedly connected to the other side of the mounting base. A first screw hole is provided on one side of the mounting base, and a second screw hole is provided on one side of the rectangular slot block. A first threaded rod is threadedly connected to the inner wall of the first screw hole and the second screw hole.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular locking groove and the rectangular locking block, two adjacent mounting seats can be installed, and at the same time, under the action of the first threaded rod, they can be fixed with the first threaded hole and the second threaded hole, thereby fixing the rectangular locking groove and the rectangular locking block, and thus allowing the mounting seats to be disassembled and assembled.

[0012] In a preferred embodiment, a rectangular card block is snapped into the inner wall of the rectangular card frame, a connecting rod is fixedly connected to one side of the rectangular card block, a resonance plate is fixedly connected to one end of the connecting rod, a resonance frame is fixedly connected to one side of the resonance plate, a third screw hole is opened at the top of the rectangular card frame, a fourth screw hole is opened at the top of the rectangular card block, and a second threaded locking rod is threadedly connected to the inner walls of the third screw hole and the fourth screw hole.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular card block and the rectangular card frame, the resonant plate can be disassembled and assembled, so that the resonant frame on the resonant plate can resonate with the internal depth and the wavelength of the noise after the noise enters, thereby converting it into heat energy and playing a role in noise reduction. Under the action of the second threaded clamp, the third screw hole and the fourth screw hole can be fixed, thereby fixing the rectangular card block and the rectangular card frame.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a soundproof shielding structure, the rectangular insert frame, along with the rectangular ring clamp frame, allows for the assembly and disassembly of the noise-reducing sponge board. This enables the replacement of the noise-reducing sponge board after it ages or becomes damaged. Simultaneously, the rectangular clamping blocks and slots allow for the splicing and fixing of two adjacent mounting bases, facilitating the replacement of damaged mounting bases and their top components. Furthermore, by setting up a resonance noise reduction structure, the rectangular clamping frame and blocks allow for the assembly and disassembly of the resonance plate. This allows the resonance frame on the resonance plate to resonate with the noise sound waves, converting the noise sound waves into heat, thus achieving noise reduction. Even after the noise-reducing sponge board ages and fails, the resonance plate can still provide noise reduction. Attached Figure Description

[0025] 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.

[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a device for blocking traffic noise on urban roads, such as... Figures 1-5 As shown, this embodiment provides a technical solution: a noise reduction device for urban roads, including a mounting base 1. A sound-insulating shielding structure 2 is provided on the top of the mounting base 1. The sound-insulating shielding structure 2 includes a rectangular insert frame 21. The bottom of the rectangular insert frame 21 is fixedly connected to the top of the mounting base 1. A rectangular ring frame 23 is inserted into the inner wall of the rectangular insert frame 21. A connecting plate 24 is fixedly connected to the top of the rectangular ring frame 23. A noise-reducing sponge board 22 is fixedly connected to the inner wall of the rectangular ring frame 23. Resonance noise reduction structures 3 are symmetrically arranged on both sides of the connecting plate 24. The resonance noise reduction structure 3 includes a rectangular frame 31. One side of the rectangular frame 31 is fixedly connected to one side of the connecting plate 24. By setting the sound-insulating shielding structure 2, under the action of the rectangular insert frame 21, it can cooperate with the rectangular ring frame 23 to reduce noise. The ring frame 23 allows for the assembly and disassembly of the noise-reducing sponge plate 22, enabling its replacement after aging or damage. Simultaneously, the rectangular locking block 210 and rectangular locking groove 29 allow for the splicing and fixing of two adjacent mounting bases 1, facilitating the replacement of damaged mounting bases 1 and their top components. By setting up the resonance noise reduction structure 3, the rectangular frame 31 and rectangular locking block 32 allow for the assembly and disassembly of the resonance plate 37, enabling the resonance frame 38 on the resonance plate 37 to resonate with the noise sound waves, converting the noise sound waves into heat, thus achieving noise reduction. Even after the noise-reducing sponge plate 22 ages and fails, the resonance plate 37 can still provide noise reduction.

[0028] Furthermore, such as Figures 2-3 As shown: A first insertion hole 25 is provided on one side of the rectangular insertion frame 21, and a second insertion hole 26 is provided on one side of the rectangular ring frame 23. A threaded insertion rod 27 is inserted into the inner wall of the first insertion hole 25 and the second insertion hole 26. A fixing nut 28 is threaded to one end of the threaded insertion rod 27. Under the action of the threaded insertion rod 27, it can be inserted into the inner wall of the first insertion hole 25 and the second insertion hole 26. At this time, the rectangular insertion frame 21 and the rectangular ring frame 23 can be fixed with the fixing nut 28. Then, the noise reduction sponge board 22 and other components can be disassembled for easy replacement or recycling after aging.

[0029] The above solutions also have the problem that the direct bonding and overlapping method when assembling mounting base 1 is unstable, and the welding method will make subsequent disassembly and assembly inconvenient. Figure 2 As shown: In this solution, a rectangular slot 29 is provided on one side of the mounting base 1, and a rectangular slot block 210 is fixedly connected to the other side of the mounting base 1. A first screw hole 211 is provided on one side of the mounting base 1, and a second screw hole 212 is provided on one side of the rectangular slot block 210. A first threaded rod 213 is threadedly connected to the inner wall of the first screw hole 211 and the second screw hole 212. Under the action of the rectangular slot 29 and the rectangular slot block 210, two adjacent mounting bases 1 can be installed. At the same time, under the action of the first threaded rod 213, it can be fixed with the first screw hole 211 and the second screw hole 212, thereby fixing the rectangular slot 29 and the rectangular slot block 210, and thus allowing the mounting base 1 to be assembled and disassembled.

[0030] The above solutions also have the problem that the noise reduction effect will decrease after the noise reduction sponge board 22 ages, and when using the resonance frame 38 for noise reduction, dust easily accumulates inside the resonance frame 38, reducing the noise reduction effect. Figure 4 and Figure 5 As shown, a rectangular clip 32 is clipped onto the inner wall of the rectangular clip 31. A connecting rod 36 is fixedly connected to one side of the rectangular clip 32. A resonant plate 37 is fixedly connected to one end of the connecting rod 36. A resonant frame 38 is fixedly connected to one side of the resonant plate 37. A third screw hole 33 is opened at the top of the rectangular clip 31, and a fourth screw hole 34 is opened at the top of the rectangular clip 32. A second threaded clip rod 35 is threadedly connected to the inner wall of the third screw hole 33 and the fourth screw hole 34. Under the action of the rectangular clip 32 and the rectangular clip 31, the resonant plate 37 can be disassembled and assembled, so that the resonant frame 38 on the resonant plate 37 can resonate with the internal depth of the resonant frame 38 and the wavelength of the noise after the noise enters, thereby converting it into heat energy and playing a role in noise reduction. Under the action of the second threaded clip rod 35, the third screw hole 33 and the fourth screw hole 34 can be fixed, thereby fixing the rectangular clip 32 and the rectangular clip 31.

[0031] Working principle:

[0032] like Figure 1-5 As shown:

[0033] In use: The mounting base 1 is spliced ​​together, the rectangular locking block 210 is engaged with the rectangular locking groove 29, and the first threaded locking rod 213 is engaged with the first screw hole 211 and the second screw hole 212 to fix the mounting base 1.

[0034] At this time, the rectangular ring frame 23 and the rectangular insertion frame 21 are fixed. At this time, the threaded insertion rod 27 is inserted into the first insertion hole 25 and the second insertion hole 26. At this time, the fixing nut 28 is fixed to the threaded insertion rod 27.

[0035] At this point, the rectangular card block 32 is snapped and fixed to the rectangular card frame 31. Then, the second threaded card rod 35 is fixed to the third screw hole 33 and the fourth screw hole 34, so that the resonant plate 37 can be installed. At this point, the sound waves of noise can resonate inside the resonant frame 38, thereby reducing noise.

[0036] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0037] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
