Description

Technical Field

[0001] This utility model belongs to the field of sound insulation technology for natural gas differential pressure generator sets, specifically a prefabricated sound insulation cover for natural gas differential pressure generator sets. Background Technology

[0002] Natural gas differential pressure generator sets generate significant noise pollution during operation. This noise primarily originates from the mechanical operation, gas flow, and combustion processes within the generator set, posing a serious threat to the surrounding environment and the physical and mental health of workers. Traditional sound insulation measures have many limitations in addressing the noise problem of natural gas differential pressure generator sets. On the one hand, some sound insulation structures are not flexible enough to adapt to generator sets of different sizes and power ratings, requiring customized designs for each set in practical applications, increasing costs and design cycles. On the other hand, traditional soundproof enclosures often present contradictions in terms of installation, maintenance, and ventilation. For example, to ensure good sound insulation, the sealing requirements of the soundproof enclosure are high, but this may lead to internal heat accumulation, affecting the normal heat dissipation of the generator set, thereby reducing power generation efficiency and even causing equipment failure. On the other hand, detachable structures designed to meet maintenance needs may damage sound insulation performance due to frequent disassembly and assembly, reducing the sound insulation effect. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a prefabricated soundproof enclosure for natural gas differential pressure generator sets, which solves the problems of traditional soundproofing measures. On the one hand, some soundproofing structures are not flexible enough and are difficult to adapt to generator sets of different sizes and power levels. On the other hand, traditional soundproof enclosures often have contradictions in terms of installation, maintenance and ventilation. For example, in order to ensure good soundproofing effect, the sealing of the soundproof enclosure is required to be high, but this may lead to the accumulation of internal heat, affecting the normal heat dissipation of the generator set and thus reducing the power generation efficiency. On the other hand, the detachable structure designed to meet maintenance needs may damage the soundproofing performance due to frequent disassembly and assembly, thus reducing the soundproofing effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated natural gas differential pressure generator set soundproof enclosure, comprising a base plate, a modular frame movably mounted on the top of the base plate via bolts, the modular frames being connected to each other via bolts, a soundproof enclosure mechanism provided on the outer wall of the modular frame, the soundproof enclosure mechanism comprising a metal microperforated plate, the metal microperforated plate being fixedly connected to the inner wall of the modular frame, a ceramic sound insulator being fixedly connected to the other end of the modular frame, an outer protective plate being fixedly connected to the outer wall of the ceramic sound insulator, a movable ceiling being movably mounted on the top plate of the soundproof enclosure mechanism at its center, and several air inlets provided on one side of the soundproof enclosure mechanism, with air inlet silencers fixedly installed between the inner walls of the air inlets.

[0005] As a further embodiment of this utility model: a plurality of exhaust vents are fixedly installed on the top of the soundproof cover mechanism, and exhaust silencers are fixedly installed between the inner walls of the exhaust vents.

[0006] As a further embodiment of this utility model: a first inspection door is rotatably connected to one side of the soundproof cover mechanism, and a first observation window is provided on one side of the first inspection door on the outer wall of the soundproof cover mechanism.

[0007] As a further embodiment of this utility model: four pillars are fixedly installed on one side of the soundproof cover mechanism above the base plate, and a movable platform is fixedly connected above the four pillars.

[0008] As a further embodiment of this utility model: an escalator is fixedly connected to one side of the activity platform, the escalator is of inclined design and its bottom end is in contact with the base plate.

[0009] As a further embodiment of this utility model: a second inspection door is rotatably connected to the other side of the soundproof cover mechanism, and a second observation window is provided on one side of the second inspection door on the outer wall of the soundproof cover mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This prefabricated natural gas differential pressure generator set soundproof enclosure, through the setting of a modular frame and soundproof enclosure mechanism, allows for easier and faster installation and disassembly of the soundproof enclosure by bolting the modular frame during use. This greatly improves on-site construction efficiency and reduces installation time and labor costs. Meanwhile, the soundproof enclosure mechanism is composed of metal microperforated plates and ceramic sound insulation bodies. The metal microperforated plates have excellent acoustic performance and can effectively reflect and absorb high-frequency noise, while the ceramic sound insulation bodies have a significant sound insulation effect on mid- and low-frequency noise. The combination of the two achieves high-efficiency sound insulation over a wide frequency range, significantly reducing the impact of noise generated by the generator set during operation on the external environment and providing a quieter working and living environment for staff and surrounding residents.

[0012] 2. This prefabricated natural gas differential pressure generator set soundproof enclosure features an air inlet, an air inlet silencer, an air outlet, and an exhaust silencer. During operation, the air inlet is located at the rear of the generator, and the exhaust outlet at the other end, creating convection within the enclosure. This effectively promotes airflow, meeting the ventilation and heat dissipation requirements of the generator set during operation. It prevents overheating due to heat accumulation, which could affect power generation efficiency and equipment lifespan. Simultaneously, the dual silencing design of the air inlet and exhaust silencers further reduces airflow noise during ventilation while ensuring smooth airflow. This avoids noise pollution caused by direct exposure of the ventilation openings, achieving dual optimization of sound insulation and ventilation / heat dissipation, thus improving the overall performance and application effect of the soundproof enclosure.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a prefabricated natural gas differential pressure generator set soundproof enclosure, including a base plate 1, a modular frame 2 movably mounted on the top of the base plate 1 by bolts, the modular frames 2 being connected to each other by bolts, and a soundproof enclosure mechanism 3 provided on the outer wall of the modular frame 2. This connection method makes the soundproof enclosure a spliced ​​structure, which facilitates large-scale inspection and maintenance of the internal equipment, reduces the workload and time of disassembly and installation, and improves maintenance efficiency. The soundproof enclosure mechanism 3 includes a metal microperforated plate 301, which is fixedly connected to the inner wall of the modular frame 2, and the other end of the modular frame 2... A ceramic sound insulation body 302 is fixedly connected, and a modular outer protective plate 303 is fixedly connected to the outer wall of the ceramic sound insulation body 302. A movable ceiling 4 is movably installed at the center of the top plate of the sound insulation cover mechanism 3. Because of the movable ceiling 4, this design allows the roof to be lifted as a whole when the equipment inside the sound insulation cover mechanism 3 is overhauled, which greatly facilitates the maintenance personnel to inspect and maintain the internal equipment, improves maintenance efficiency, and reduces maintenance time and labor costs. At the same time, the position of the movable ceiling 4 corresponds to the platform equipment, which further enhances the flexibility and adaptability of the sound insulation cover and can better meet the installation and maintenance needs of different equipment.

[0020] The soundproof enclosure mechanism 3 has several air inlets 5 on one side, and air inlet silencers 6 are fixedly installed between the inner walls of the air inlets 5. The soundproof enclosure mechanism 3 has several exhaust vents 7 fixedly installed on the top, and exhaust silencers 8 are fixedly installed between the inner walls of the exhaust vents 7. Through the cooperation between the air inlets 5 and the exhaust vents 7, the air organization changes. The air inlets 5 are located at the tail of the generator, and the exhaust vents 7 are located at the other end of the soundproof enclosure, so that convection is formed in the room, which is conducive to the ventilation and heat dissipation of the generator set inside the soundproof enclosure, while reducing the propagation of noise. This provides a guarantee for the stable operation of the generator set and reduces noise pollution. It not only meets the heat dissipation requirements of the generator set operation, but also effectively reduces the impact of noise on the surrounding environment.

[0021] A first inspection door 9 is rotatably connected to one side of the soundproof enclosure mechanism 3. A first observation window 10 is provided on one side of the first inspection door 9 on the outer wall of the soundproof enclosure mechanism 3. Because of the first observation window 10, it is convenient for staff to observe the internal equipment from outside the soundproof enclosure without having to frequently enter the soundproof enclosure, which improves work efficiency. At the same time, it also reduces the impact and interference that may be caused to the internal equipment due to frequent entry and exit of the soundproof enclosure, and enhances the stability and safety of the equipment operation inside the soundproof enclosure. A second inspection door 14 is rotatably connected to the other side of the soundproof enclosure mechanism 3. A second observation window 15 is provided on one side of the second inspection door 14 on the outer wall of the soundproof enclosure mechanism 3.

[0022] Four support columns 11 are fixedly installed on one side of the soundproof enclosure mechanism 3 above the base plate 1. A movable platform 12 is fixedly connected above the four support columns 11. The movable platform 12 provides stable support and operating space for maintenance work, further improving the convenience and safety of maintenance work and reducing the risk to workers when working at height. A ladder 13 is fixedly connected to one side of the movable platform 12. The ladder 13 is inclined and its bottom end is in contact with the base plate 1. The ladder 13 provides workers with a convenient way to go up and down, making it easy for them to quickly reach the movable platform 12 to operate and maintain the top of the soundproof enclosure mechanism 3 or related equipment.

[0023] The working principle of this utility model is as follows: When using the soundproof enclosure, the module frame 2 is first installed on the base plate 1 with bolts, and then the module frames 2 are connected with bolts to form the main frame structure of the soundproof enclosure mechanism 3. Subsequently, the metal microporous plate 301 is fixedly connected to the inner wall of the module frame 2 to play a preliminary sound insulation role. The ceramic sound insulation body 302 is fixedly connected to the other end of the module frame 2 to further enhance the sound insulation effect and effectively block the noise generated by the generator set from spreading outward. When the generator set is running, the air inlet 5 and the air outlet 7 are located at both ends of the soundproof enclosure structure, respectively. When dissipating heat, the air inlet 5 and the air outlet 7 form convection in the room to dissipate heat from the generator set. At the same time, the air inlet silencer 6 and the air outlet silencer 8 reduce the spread of noise. When the generator is working inside the soundproof enclosure, the staff can enter the inside of the soundproof enclosure through the first inspection door 9 or the second inspection door 14 to inspect and maintain the equipment. They can also check the operating status of the equipment inside the soundproof enclosure at any time through the first observation window 10 and the second observation window 15.
