Description

Technical Field

[0001] This utility model relates to the field of noise control and silencing equipment technology, specifically a high-efficiency noise reduction silencer device. Background Technology

[0002] With the continuous acceleration of industrialization and urbanization, noise pollution has become one of the major global environmental problems. In many fields such as industrial production, transportation, and people's daily lives, the operation and activities of various mechanical equipment generate a large amount of noise, which seriously affects people's health and quality of life.

[0003] Traditional silencers still have the following drawbacks when in use: they are inconvenient to install and maintain. Some silencers have complex structures and large sizes, which makes them inconvenient to install and maintain, limiting their application in certain situations. On the other hand, if the equipment connected to the silencer itself vibrates a lot and the silencer does not take effective vibration reduction measures, the vibration of the equipment will be transmitted to the silencer, causing it to shake. Long-term vibration may also lead to fatigue damage to the connection parts of the silencer, further aggravating the shaking. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency noise reduction and silencer device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency noise reduction silencer device, comprising a supporting base plate, characterized in that: a damper is provided on the upper surface of the supporting base plate, a spring is sleeved on the damper, one end of the spring is connected to the supporting base plate, and the other end is connected to a connecting block, a shell is fixedly connected to the connecting block, sound-absorbing cotton is provided inside the shell, the sound-absorbing cotton is disposed on the outside of the silencer tube, a rotating connecting shaft is rotatably connected to the inner side of the shell, a silencer louver is rotatably connected to one end of the rotating connecting shaft, a micro-perforated tube is fixedly connected to one end of the shell near the silencer louver, and a connecting plate is provided at one end of the micro-perforated tube for connecting a silencer elbow.

[0006] As a further description of the above technical solution: the damper, spring and connecting block are provided in multiple sets, and the damper and spring are evenly distributed at the four corners of the supporting base plate.

[0007] As a further description of the above technical solution: the rotating connecting shaft is located at both ends of the sound-absorbing louver and there are multiple sets thereto, and the angle of the sound-absorbing louver can be adjusted by rotating the connecting shaft.

[0008] As a further description of the above technical solution: the micro-perforated tube has small holes of the same diameter evenly distributed on it.

[0021] 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.

[0022] Example 1:

[0023] like Figures 1-4 As shown, one embodiment of this utility model is provided: a high-efficiency noise reduction silencer device, including a supporting base plate 1, characterized in that: a damping 2 is provided on the upper surface of the supporting base plate 1, a spring 3 is sleeved on the damping 2, one end of the spring 3 is connected to the supporting base plate 1, and the other end is connected to the connecting block 4, a shell 5 is fixedly connected to the connecting block 4, a sound-absorbing cotton 6 is provided inside the shell 5, the sound-absorbing cotton 6 is disposed on the outside of the silencer tube 7, a rotating connecting shaft 8 is rotatably connected to the inner side of the shell 5, a silencer louver 9 is rotatably connected to one end of the rotating connecting shaft 8, a micro-perforated tube 10 is fixedly connected to one end of the shell 5 near the silencer louver 9, a connecting plate 11 is provided at one end of the micro-perforated tube 10 for connecting a silencer elbow 12.

[0024] In this embodiment, when the device is subjected to vibration caused by noise, the damping 2 and spring 3 can prevent the internal structure of the device from becoming loose or damaged under large vibrations.

[0025] Specifically, multiple sets of dampers 2, springs 3, and connecting blocks 4 are provided, with dampers 2 and springs 3 evenly distributed at the four corners of the supporting base plate 1.

[0026] It should be noted that when noise causes vibration, the dampers 2 and springs 3 at the four corners can evenly distribute the vibration energy, prevent the vibration from causing the entire device to shake, and ensure the stable operation of the subsequent noise reduction structure, providing a solid foundation for the noise reduction process.

[0027] Example 2:

[0028] Based on Example 1, the direction and intensity of noise propagation may vary under different environments. By adjusting the angle of the noise-absorbing louvers, the propagation path of noise can be blocked and dispersed more effectively.

[0029] Specifically, the rotating connecting shaft 8 is located at both ends of the sound-absorbing louver 9 and there are multiple sets of them. The angle of the sound-absorbing louver 9 can be adjusted by rotating the connecting shaft 8.

[0030] It should be noted that the angle of the sound-absorbing louvers can be adjusted according to the direction and intensity of the noise source, which can control the propagation path of the noise. This can effectively block the noise while ensuring normal air circulation, without affecting the heat dissipation and air circulation of the equipment.

[0031] Example 3:

[0032] Based on Example 2, noise enters the micro-perforated tube 10, which can disperse the noise into sound waves in multiple directions.

[0033] Specifically, the micro-perforated tube 10 has small holes of the same diameter evenly distributed on it.

[0034] It should be noted that evenly distributed small holes with the same aperture can cause noise to disperse and reflect evenly in all directions after it enters, thus attenuating noise of different frequencies.

[0035] Specifically, the silencing elbow 12 is L-shaped.

[0036] It should be noted that the L-shaped design extends the noise propagation path. The noise changes direction at the bend, and after multiple reflections and interferences, the energy is further reduced, enhancing the noise reduction effect.

[0037] Specifically, the sound-absorbing cotton 6 is tightly attached to the inner wall of the outer shell 5 and the outer wall of the silencer tube 7.

[0038] It should be noted that the tightly fitted sound-absorbing cotton 6 can quickly absorb noise energy and convert it into heat energy to dissipate, reducing the reflection and propagation of noise inside the device and improving the noise reduction effect.

[0039] Specifically, the connecting plate 11 has holes with the same diameter as the silencing elbow 12.

[0040] It should be noted that the silencing elbow 12 is tightly connected to the connecting plate 11 to prevent noise leakage from the connection point, so that the noise propagates and attenuates along a predetermined path within the silencing system.

[0041] Working principle: In practical applications, the user first places the device at the location where noise reduction and silencing are required. Then, the tilt angle of the silencing louvers 9 can be adjusted by rotating the connecting shaft 8 as needed. The damping 2 and spring 3 on the support base plate 1 work together to keep the device stable under the large vibration caused by noise. Then, the noise enters the outer shell 5. The silencing tube 7 and sound-absorbing cotton 6 can absorb some of the noise when it enters. The silencing louvers 9 can reduce the transmission of noise while allowing air to circulate. The micro-perforated tube 10 can effectively disperse the noise. The silencing elbow 12 can effectively reduce the transmission of noise during the air delivery process.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
