Description

Technical Field

[0001] The utility model relates to the technical field of soundproof rooms, in particular to a soundproof room structure for a generator. Background Art

[0002] In industrial environments, generators generate high-decibel noise when running. Without a soundproof room, this noise will spread to the surrounding environment, causing noise pollution to the surrounding area. The installation of a soundproof room can play a role in hearing protection.

[0003] The soundproof room of the generator is a square structure composed of multiple soundproof walls. The generator is located inside the soundproof room. When the generator is working, the soundproof room can effectively reduce the impact of the noise generated by the generator on nearby residents. However, some generators will produce a large amount of exhaust gas when working. There is a lot of dust and oil smoke in the exhaust gas. The oil smoke easily adheres to the rock wool used for sound insulation in the soundproof room walls, which is inconvenient for users to clean. At the same time, dust and oil smoke will clog the pores on the rock wool, which will seriously affect the sound insulation effect of the soundproof room. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 3 In the utility model: a sound insulation room structure for a generator, comprising an outer layer 1, the outer layer 1 is a steel plate, a sound insulation layer 2 is provided on one side of the outer layer 1, a buffer sleeve 3 fixedly connected to the sound insulation layer 2 is sleeved on the sound insulation layer 2, one side of the buffer sleeve 3 is fixedly connected to the outer layer 1, and the other side of the buffer sleeve 3 is fixedly connected to a sound absorbing layer 4, one side of the sound absorbing layer 4 is fixedly connected to two mounting rods 5, a protective layer 6 is provided on one side of the sound absorbing layer 4, two mounting holes 7 adapted to the mounting rods 5 are provided on the protective layer 6, and nuts 8 threadedly connected to the two mounting rods 5 are sleeved on the two mounting rods 5; the sound insulation layer 2 is a rock wool layer, the buffer sleeve 3 is a rubber layer, and the sound absorbing layer 4 is a perforated sound absorbing board; the protective layer 6 is a porous ceramic composite board, and the protective layer 6 is coated with an oleophobic coating.

[0024] In the present invention, the outer layer 1 is a steel plate with high strength, which can resist external impact and protect the internal structure. The sound insulation layer 2 is a rock wool layer made of sound insulation material. The rock wool has a large density and a good sound insulation effect, which can effectively block the propagation of sound. The sound absorption layer 4 is a perforated sound absorption board layer made of sound absorption material, which can absorb the noise generated by the generator and reduce reflected sound. The protective layer 6 is a porous ceramic composite board. The ceramic part in the porous ceramic composite board has a porous structure. These pores can absorb oil molecules. The adsorption principle is based on physical adsorption, that is, the oil molecules are attracted by the pore surface and fixed in the pores. At the same time, the porous ceramic surface can be treated with a special oleophobic coating, such as a fluoropolymer coating. This coating has extremely low surface energy, making it difficult for oil to spread on the surface. Development, thereby achieving an oleophobic effect. For example, when the oil stains generated by the generator are close to the porous ceramic composite plate, the oil stain molecules first contact the oleophobic coating. Most of the oil stains will form droplets and slide down, while a small amount of oil stains that enter the pores will be adsorbed in the pores of the ceramic, reducing the frequency of cleaning by users. Moreover, the porous ceramics themselves have certain sound insulation properties. When sound propagates in the porous structure, it will continuously reflect and refract in the pores. The sound energy is consumed and converted into heat energy, thereby reducing the propagation of sound and further improving the sound insulation effect of the structure. The outer layer 1, the sound insulation layer 2, the buffer sleeve 3, the sound absorbing layer 4 and the protective layer 6 constitute a partition wall, which is part of the soundproof room. Multiple such partition wall structures can constitute a complete soundproof room for soundproofing the generator.

[0025] Buffer sleeve 3 is a rubber sleeve. Its presence primarily serves to cushion and reduce vibrations in the sound insulation layer 2. When the rock wool layer is exposed to a vibration source, such as near a generator, the rubber sleeve absorbs and cushions the vibrations. It converts external vibration energy into elastic potential energy within the rubber, reducing the direct transmission of vibration to the rock wool and protecting its structural integrity. Vibration causes friction between the fibers within the rock wool. Long-term friction can lead to fiber wear and breakage. The shock-absorbing effect of the rubber sleeve reduces this vibration-induced internal fiber friction, helping to maintain the rock wool's sound absorption properties. The rubber sleeve also fills any gaps between the rock wool and surrounding structures (such as walls and frames). If these gaps are left unaddressed, sound waves may propagate through them, reducing the overall sound insulation. The presence of the rubber sleeve effectively prevents sound waves from leaking through these gaps, thereby enhancing the overall sound insulation to a certain extent.

[0026] The thickness of the protective layer 6 decreases from top to bottom, and a collecting box 9 is fixedly connected to the left side of the protective layer 6; an oil absorbing layer 10 is fixedly connected to the inner wall of the collecting box 9, and the oil absorbing layer 10 is an oil absorbing sponge.

[0027] In the present invention, the thickness of the protective layer 6 decreases from top to bottom, which can have a diversion effect on the attached oil stains. The oil stains will drip along the protective layer 6 into the collection box 9 and be absorbed by the oil absorption layer 10, which is convenient for the user to clean and improve the practicality of the device. The user can also rotate the nut 8 to remove the protective layer 6 from the mounting rod 5 for cleaning, thereby improving the practicality of the device.

[0028] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
