Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction devices, in particular to an environmentally friendly sound insulation device for decoration engineering construction. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, decoration projects are in full swing in various cities. However, the noise pollution problem generated during the decoration construction process is becoming increasingly prominent. Construction noise not only affects the life and work of surrounding residents, but may also have adverse effects on the health of construction workers. Therefore, the development of an efficient and environmentally friendly sound insulation device is of great significance to reducing construction noise and improving the living environment.

[0003] In the prior art, there are some sound insulation devices for decoration construction noise. For example, Chinese invention patent CN115030339B discloses an easy-to-use noise reduction and sound insulation board, which includes multiple noise reduction boards, slide rails and locking members that are rotatably connected to each other. The noise reduction board is provided with a slider that is slidably connected to the slide rail; the locking member includes two tensioning springs, a connecting rod and a locking rod. Through the rotation of adjacent noise reduction boards and the action of the tensioning springs, the noise reduction boards can be quickly installed and locked without locking adjacent noise reduction boards one by one, which saves time and effort, reduces the use of unnecessary decoration materials, and is beneficial to environmental protection.

[0004] Another Chinese utility model patent, CN221346569U, discloses a sound insulation device for decoration that is easy to disassemble and install. The device includes a receiving plate, a support sleeve, a second motor, a threaded column, a threaded sleeve, a lifting column, and a sound insulation board. The threaded column is driven to rotate by the second motor, which drives the threaded sleeve and the lifting column to rise and fall, thereby adjusting the height of the sound insulation board to meet the different height requirements of the construction site. This design realizes the height adjustment function of the sound insulation board, which is convenient for installation and disassembly at the construction site.

[0005] The above two designs achieve rapid installation, disassembly and height adjustment of sound insulation boards by improving the installation method and structure of sound insulation boards, thereby improving construction efficiency and playing a positive role in environmental protection and construction convenience. However, the existing technology still has certain limitations. The above patents mainly focus on the installation convenience and adaptability of sound insulation boards, and the sound insulation performance of the sound insulation boards themselves is insufficiently improved. The sound insulation effect mainly relies on traditional sound insulation materials, lacks multiple reflections, absorption and intelligent adjustment of sound waves, and is difficult to efficiently reduce noise of various frequencies generated during the construction process. Existing sound insulation devices are usually fixed structures and cannot be adjusted according to the real-time changes in noise intensity and frequency at the construction site. It cannot achieve adaptive sound insulation for different noise environments, resulting in poor sound insulation effect. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an environmentally friendly sound insulation device for decoration engineering construction to solve the above-mentioned problems.

[0007] The purpose of the utility model is achieved through the following technical solutions: an environmentally friendly sound insulation device for decoration engineering construction, comprising a plurality of frames, a fixing plate fixedly connected to the frame, and a plurality of sound-absorbing holes opened on the fixing plate;

[0008] An adjustment ring is slidably connected in each muffler hole, and ends of the multiple adjustment rings away from the fixed plate are fixedly connected to the same adjustment plate 1 and all pass through the adjustment plate 1;

[0011] A plurality of driving blocks 1 are fixedly connected between the fixed plate and the adjusting plate 1, and a plurality of driving blocks 2 are fixedly connected between the adjusting plate 1 and the adjusting plate 2;

[0012] Each adjusting rod is fixedly connected to a wedge at one end away from the adjusting plate 2, and the wedge is a wedge-shaped structure with the tip facing away from the adjusting rod;

[0013] A reflection ring is fixedly connected to the end of each muffler hole away from the adjustment hole;

[0014] The ends of the fixing plate and the second adjusting plate away from the first adjusting plate are both provided with a plurality of sensors for detecting noise.

[0015] Through the multi-layer sound-absorbing structure, special geometric design and material density gradient, sound waves are reflected, refracted and absorbed multiple times inside the device, and the energy is gradually dissipated, reducing the propagation of noise.

[0016] The device is equipped with sensors and drive blocks made of piezoelectric materials, which can monitor noise conditions in real time and automatically adjust the internal structure to adapt to noise environments of different frequencies and intensities, always maintaining the best sound insulation effect.

[0017] Adjacent frames are connected by rotating shafts and flexible connecting blocks. The device can be adjusted in angle and shape according to the needs of the construction site and has a wide range of adaptability.

[0018] It uses environmentally friendly materials such as foam materials and piezoelectric materials, has good sound absorption performance, is light in weight, and is easy to install and disassemble, meeting the requirements of green construction.

[0019] Through efficient sound insulation, the impact of construction noise on the surrounding environment and personnel is reduced, disputes and penalties caused by noise nuisance are reduced, and the social image and economic benefits of construction companies are improved.

[0020] Two adjacent frames are rotatably connected via a rotating shaft and are fixedly connected with a connecting block.

[0021] The connecting block is made of a flexible material and is provided with a through slot for accommodating the rotating shaft at a position corresponding to the rotating shaft.

[0022] The fixing plate is a hollow structure, and the hollow part is filled with granular sound-absorbing material; the cross section of the silencer hole is a hexagonal structure, and the cross sections of the adjustment ring and the adjustment rod are also hexagonal structures; the wedge block is a hexagonal pyramid structure.

[0023] The adjusting ring and the adjusting rod are both made of foam material; the driving block 1 and the driving block 2 are both made of piezoelectric material.

[0024] The reflective ring is composed of a plurality of coaxially arranged hexagonal rings, and the distance between two adjacent hexagonal rings is 1 to 3 mm; a through hole for allowing noise to enter is opened in the center of the plurality of hexagonal rings along the axis direction of the silencer hole.

[0025] The outer ends of the adjusting plate 1 and the adjusting plate 2 are both slidably connected to the inner wall of the frame; the material density of the adjusting ring, the adjusting plate 1, the wedge, the adjusting rod and the adjusting plate 2 gradually increases.

[0026] The beneficial effects of the utility model are:

[0027] 1. The interior of the device consists of a multi-layer sound-absorbing structure composed of components such as a fixed plate, adjustment plate 1, adjustment plate 2, adjustment ring, adjustment rod and wedge. When sound waves pass through these layers, the energy is absorbed and dissipated layer by layer, significantly reducing the propagation of noise.

[0028] The silencer hole, adjustment ring, and adjustment rod all have hexagonal cross-sections, and the wedge is a hexagonal pyramid structure. These special geometric shapes increase the number of reflections and scatterings of sound waves inside the device, extend the propagation path of the sound waves, and enhance the sound absorption effect.

[0029] The reflection ring is composed of multiple coaxially arranged hexagonal rings, with a distance of 1 to 3 mm between adjacent rings and a through hole in the center. This structure causes sound waves to produce multiple reflections and diffractions when entering the device, further weakening the sound wave energy.

[0030] 2. The adjustment ring and adjustment rod are made of foam material, which has excellent sound absorption performance and lightweight characteristics. It can effectively absorb sound waves, reduce the weight of the device, and facilitate installation and movement.

[0031] Driving block one and driving block two are made of piezoelectric material, which can produce deformation when voltage is applied, thereby achieving precise control of the position of adjustment plate one and adjustment plate two, and enhancing the intelligent adjustment capability of the device.

[0032] The material density of the adjustment ring, adjustment plate 1, wedge, adjustment rod and adjustment plate 2 gradually increases to form a density gradient. Sound waves are reflected and refracted at the interface of materials with different densities, which increases the attenuation times and paths of the sound waves and improves the sound insulation effect.

[0033] 3. Multiple sensors are installed on the fixed plate and the adjustment plate 2 to detect the intensity and frequency information of the noise in real time. According to the detection results, the driving block 1 and the driving block 2 can adjust the position of the adjustment plate 1 and the adjustment plate 2, change the internal structure, and achieve effective control of noises of different frequencies and intensities.

[0034] By utilizing the characteristics of piezoelectric materials, driver blocks one and two can perform precise deformation on a microscopic scale, making the adjustment of the internal structure more flexible, accurate and adaptable.

[0035] The outer ends of the adjustment plate 1 and the adjustment plate 2 are slidably connected to the inner wall of the frame, ensuring a smooth adjustment process, avoiding inaccurate adjustment due to friction or resistance, and improving the stability and durability of the device.

[0036] 4. Adjacent frames are connected by rotating shafts and connecting blocks made of flexible materials, which not only ensures the overall stability of the device but also provides a certain degree of flexibility, making it convenient to adjust the angle and shape of the device according to site needs and adapt to different construction environments.

[0037] The fixing plate is a hollow structure filled with granular sound-absorbing material, which further enhances the overall sound absorption performance of the device.

[0038] 5. Sound waves undergo multiple reflections, refractions, and absorptions within the multi-layered structure and special materials within the device, and their energy is gradually dissipated, significantly reducing the propagation of noise.

[0039] The hexagonal pyramid structure of the wedge, with the tip facing away from the adjustment rod, increases the reflection path of the sound waves, causing more reflection and scattering of the sound waves inside, thereby enhancing the sound absorption effect.

[0040] 6. Due to the use of foam materials and other lightweight materials, the overall weight of the device is reduced, which is convenient for transportation, installation and disassembly, and is suitable for various decoration construction environments.

[0041] Through real-time monitoring by sensors and precise adjustment of the drive block, the device can automatically adjust its internal structure according to different noise types and intensities, always maintaining the best sound insulation effect.

[0042] 7. The foam materials, piezoelectric materials, etc. used in the device are all environmentally friendly materials, have no pollution to the environment, and meet the requirements of green construction.

[0043] The driving block is made of piezoelectric material, which has low energy consumption and only consumes a small amount of electricity when adjustment is required, saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0055] It is to be noted that the directions of "left", "right", "up", "down", "front", "back", "inside" and "outside" in the following schemes are all relative directions and are not listed here one by one.

[0056] Example 1:

[0057] like Figures 1 to 8 As shown, this embodiment provides an environmentally friendly sound insulation device for decoration engineering construction, including multiple frames 1, a fixed plate 2 is fixedly connected to the frame 1, a plurality of silencer holes 3 are opened on the fixed plate 2, and an adjustment ring 4 is slidably connected to each silencer hole 3. The ends of the multiple adjustment rings 4 away from the fixed plate 2 are fixedly connected to the same adjustment plate 15 and all pass through the adjustment plate 15. An adjustment hole 16 is opened in each adjustment ring 4, and an adjustment rod 7 is slidably connected to each adjustment hole 6. The ends of the multiple adjustment rods 7 away from the adjustment ring 4 are fixedly connected to the same An adjustment plate 2 8, multiple driving blocks 10 are fixedly connected between the fixed plate 2 and the adjustment plate 1 5, and multiple driving blocks 2 10 are fixedly connected between the adjustment plate 1 5 and the adjustment plate 2 8. Each adjustment rod 7 is fixedly connected to a wedge 11 at one end away from the adjustment plate 2 8. The wedge 11 is a wedge-shaped structure with the tip facing away from the adjustment rod 7. A reflection ring 12 is fixedly connected to the end of each silencer hole 3 away from the adjustment hole 1 6. Multiple sensors for detecting noise are provided on the ends of the fixed plate 2 and the adjustment plate 2 8 away from the adjustment plate 5.

[0058] Two adjacent frames 1 are rotatably connected via a rotating shaft 13 and are fixedly connected with a connecting block 14 . The connecting block 14 is made of a flexible material and has a through slot for accommodating the rotating shaft 13 at a position corresponding to the rotating shaft 13 .

[0059] The fixing plate 2 is a hollow structure, and the hollow part is filled with granular sound-absorbing material. The cross section of the silencer hole 3 is a hexagonal structure, the cross section of the adjustment ring 4 and the adjustment rod 7 is also a hexagonal structure, and the wedge block 11 is a hexagonal pyramid structure.

[0060] Working process:

[0061] When in use, multiple frames 1 are placed in the area where sound insulation is required, and the end of the fixing plate 2 away from the adjusting plate 28 faces the direction of the noise. The angle between two adjacent frames 1 is adjusted by the rotating shaft 13 to adapt to different environments and spatial layouts. In the process of adjusting the angle of the frame 1, the connecting block 14 is made of flexible material and can produce elastic deformation to ensure the stability and flexibility of the connection between the frames 1.

[0062] When noise is generated, the sound wave first enters the silencer hole 3 through the reflection ring 12. The design of the reflection ring 12 helps to guide the sound wave into the silencer hole 3. After entering the silencer hole 3, the sound wave encounters the adjustment hole 16 and the wedge 11. At this time, the adjustment hole 16, the adjustment rod 7 and the wedge 11 initially absorb and attenuate the sound wave. The wedge 11 is a hexagonal pyramid structure with the tip facing away from the adjustment rod 7. Its special geometric shape increases the reflection path of the sound wave, causing the sound wave to be reflected multiple times in the silencer hole 3.

[0063] After being reflected by the wedge 11, the remaining sound waves are reflected back and forth in the space surrounded by the silencer hole 3, the adjustment hole 6, the wedge 11 and the reflection ring 12. Since the silencer hole 3, the adjustment ring 4 and the adjustment rod 7 all have a hexagonal cross-sectional structure, this shape is conducive to multiple reflections and absorption of the sound waves inside, reducing the transmission of the sound waves.

[0064] At the same time, the fixing plate 2 is a hollow structure filled with granular sound-absorbing material. When sound waves pass through the fixing plate 2, the granular sound-absorbing material further absorbs and dissipates the sound waves, reducing the energy of the sound waves.

[0065] The sensors on the fixed plate 2 and the adjustment plate 2 8 detect the intensity and frequency information of the noise in real time. According to the detected noise situation, the driving block 1 9 and the driving block 2 10 can appropriately adjust the positions of the adjustment plate 1 5 and the adjustment plate 2 8. The driving block 1 9 is fixedly connected between the fixed plate 2 and the adjustment plate 1 5, and the driving block 2 10 is fixedly connected between the adjustment plate 1 5 and the adjustment plate 2 8. Through the extension and retraction of the driving block 1 9 and the driving block 2 10, the relative positions of the adjustment plate 1 5, the adjustment plate 2 8, the adjustment ring 4, the adjustment rod 7 and the wedge block 11 are adjusted, thereby changing the sound wave reflection and absorption effect in the silencer hole 3 to achieve the best sound insulation effect.

[0066] By providing components such as the silencer hole 3, the adjustment ring 4, the adjustment rod 7 and the wedge block 11, sound waves are reflected and absorbed multiple times inside the device, and the energy is gradually dissipated, thereby achieving a highly efficient sound insulation effect.

[0067] Driving block 1 9 and driving block 2 10 can adjust the relative positions of adjusting plate 1 5 and adjusting plate 2 8 in real time according to the noise conditions detected by the sensor, and then adjust the internal structure to achieve effective control of noises of different frequencies and intensities.

[0068] Adjacent frames 1 are connected via a rotating shaft 13 and a flexible connecting block 14, which not only ensures the overall stability of the device but also provides a certain degree of flexibility, making it convenient for the device to adjust its angle and position according to actual needs.

[0069] The fixing plate 2 is a hollow structure filled with granular sound-absorbing material to further absorb and dissipate sound waves, thereby enhancing the overall sound insulation performance of the device.

[0070] The silencer hole 3, the adjustment ring 4 and the adjustment rod 7 all have hexagonal cross sections, and the wedge 11 has a hexagonal pyramid structure. This special geometric shape is conducive to multiple reflections and scattering of sound waves inside, thereby improving the absorption efficiency of sound waves and reducing the transmittance of sound waves.

[0071] The multiple sensors on the fixed plate 2 and the adjustment plate 2 8 can monitor the changes in noise in real time and provide accurate data support, so that the driving block 1 9 and the driving block 2 10 can respond in time, adjust the internal structure of the device, and always maintain the best sound insulation effect.

[0072] The device has a reasonable structural design and is easy to install and disassemble. It is suitable for various decoration engineering construction environments, can effectively reduce noise pollution during the construction process, and protect the health of construction workers and surrounding residents.

[0073] This embodiment provides a highly efficient and environmentally friendly sound insulation device through structural design and material selection. Through the cooperation of the multi-layer structure and adjustable components, the sound waves are reflected, scattered and absorbed multiple times inside the device, and the energy is gradually dissipated, achieving a significant sound insulation effect. The application of drive block 1 9 and drive block 2 10 makes the device have good adjustability and intelligence level, and can be adjusted according to the actual noise situation to ensure the best sound insulation performance. The overall structure is stable, has certain flexibility, and strong adaptability. It is suitable for various decoration engineering construction sites, effectively reduces noise pollution, and is of great significance to environmental protection and people's health.

[0074] Example 2:

[0075] like Figures 1 to 8 As shown, based on Example 1, this example further optimizes and improves the environmentally friendly sound insulation device to enhance its sound insulation effect and intelligent adjustment capability.

[0076] The adjusting ring 4 and the adjusting rod 7 are both made of foam material. The foam material has good sound absorption performance and light weight characteristics, can effectively absorb sound wave energy, reduce the overall weight of the device, and facilitate installation and movement.

[0077] Both driving block 1 9 and driving block 2 10 are made of piezoelectric material, which can deform when voltage is applied. By utilizing this characteristic, the expansion and contraction of driving block 1 9 and driving block 2 10 can be precisely controlled, thereby achieving precise adjustment of the positions of adjustment plate 1 5 and adjustment plate 2 8.

[0078] The reflection ring 12 is composed of multiple coaxially arranged hexagonal rings, and the distance between two adjacent hexagonal rings is 1 to 3 mm. A through hole for allowing noise to enter is opened in the center of the multiple hexagonal rings along the axis of the silencer hole 3. Such a structural design can increase the path length of the sound wave entering the reflection ring 12, causing the sound wave to produce multiple reflections and diffractions between the multiple hexagonal rings, further weakening the energy of the sound wave.

[0079] The outer ends of the adjustment plate 1 5 and the adjustment plate 2 8 are both slidably connected to the inner wall of the frame 1. Through the sliding connection, the adjustment plate 1 5 and the adjustment plate 2 8 can move smoothly along the inner wall of the frame 1 under the action of the driving block 1 9 and the driving block 2 10 to adjust the relative position of the internal structure.

[0080] The material density of the adjustment ring 4, the adjustment plate 1 5, the wedge 11, the adjustment rod 7 and the adjustment plate 2 8 gradually increases, that is, starting from the adjustment ring 4, to the adjustment plate 1 5, the wedge 11, the adjustment rod 7, and the adjustment plate 2 8, the material density gradually increases, forming a gradient distribution of material density. This design helps sound waves to be reflected and refracted at the interface of materials with different densities, increases the propagation path of sound waves, and enhances the attenuation effect of sound waves.

[0081] Working process:

[0082] During use, the basic installation method of the device is the same as that of Example 1. Multiple frames 1 are placed in the area where sound insulation is required, and the end of the fixing plate 2 away from the adjustment plate 2 8 faces the noise source. The angle between adjacent frames 1 is adjusted by the rotating shaft 13. The connecting block 14 is made of flexible material and can produce elastic deformation to ensure the stability of the connection between the frames 1.

[0083] When noise is generated, the sound wave first enters the silencer hole 3 through the through hole of the reflection ring 12. Since the reflection ring 12 is composed of multiple coaxially arranged hexagonal rings, and the distance between adjacent hexagonal rings is 1 to 3 mm, the sound wave will produce multiple reflections and diffractions between the multiple hexagonal rings during the entry process, which weakens the energy of the sound wave.

[0084] After entering the silencer hole 3, the sound wave encounters the adjustment ring 4 and the adjustment rod 7 made of foam material. The foam material has good sound absorption performance and can initially absorb and attenuate the sound wave. Then, the sound wave reaches the wedge block 11. The wedge block 11 is a component with a higher material density. Its hexagonal pyramid structure increases the reflection path of the sound wave, causing the sound wave to produce more reflection and scattering in the silencer hole 3.

[0085] During this process, since driving block 1 9 and driving block 2 10 are made of piezoelectric material, they can adjust their own length according to the noise conditions detected in real time by the sensors on the fixed plate 2 and the adjustment plate 2 8. By controlling the voltage applied to driving block 1 9 and driving block 2 10, they produce precise deformation, pushing the adjustment plate 1 5 and the adjustment plate 2 8 to move. The adjustment plate 1 5 and the adjustment plate 2 8 move smoothly on the inner wall of the frame 1 through the sliding connection, driving the adjustment ring 4, adjustment rod 7 and wedge block 11 connected thereto to adjust their positions.

[0086] As the material density of the adjustment ring 4, adjustment plate 1 5, wedge 11, adjustment rod 7 and adjustment plate 2 8 gradually increases, sound waves will be reflected and refracted at the interface of materials with different densities during propagation. By adjusting the positions of these components, the propagation path and number of reflections of the sound waves inside the device can be changed, thereby optimizing the absorption and attenuation effects of sound waves of different frequencies.

[0087] The adjusting ring 4 and the adjusting rod 7 are made of foam material, which has good sound absorption performance and can effectively and preliminarily absorb the sound waves entering the device and reduce the energy of the sound waves.

[0088] Driving block 1 9 and driving block 2 10 are made of piezoelectric material, which can produce precise deformation when voltage is applied, thereby achieving precise control of the positions of adjustment plate 1 5 and adjustment plate 2 8, and then finely adjusting the internal structure to improve the sound insulation effect.

[0089] The reflection ring 12 is composed of a plurality of coaxially arranged hexagonal rings, which increases the number of reflections and diffractions of the sound wave when it enters the device, extends the propagation path of the sound wave, and further weakens the energy of the sound wave.

[0090] The outer ends of the adjustment plate 1 5 and the adjustment plate 2 8 are slidably connected to the inner wall of the frame 1, so that they can move smoothly under the action of the driving block 1 9 and the driving block 2 10, avoiding inaccurate adjustment caused by shaking or resistance, and improving the stability and durability of the device.

[0091] The material density of the adjustment ring 4, the adjustment plate 1 5, the wedge 11, the adjustment rod 7 and the adjustment plate 2 8 gradually increases to form a density gradient distribution. The reflection and refraction effects of sound waves at the interface of materials with different densities increase the number of attenuation times and paths of the sound waves, effectively improving the sound insulation effect of the device for sound waves of different frequencies.

[0092] Through the application of piezoelectric materials and sliding connection structure, the device can quickly respond to changes in external noise, adjust internal structural parameters in real time, adapt to different noise environments, and always maintain optimal sound insulation performance.

[0093] On the basis of Example 1, through the optimized design of materials and structures, the environmentally friendly sound insulation device of Example 2 has been significantly improved in terms of sound insulation effect, adjustment accuracy, adaptability and durability, etc., and can better meet the sound insulation needs of the decoration construction site and reduce the impact of noise on the environment and personnel.

[0094] This embodiment optimizes the materials of key components and adopts foam materials and piezoelectric materials to improve the sound absorption performance and adjustment accuracy of the device. The structural improvement of the reflection ring 12 enhances the reflection and attenuation effect when the sound waves enter the device. The design of the material density gradient allows the sound waves to undergo multiple reflections, refractions and absorptions inside the device, and the energy is effectively dissipated. The sliding connection between the adjustment plate 1 5 and the adjustment plate 2 8 ensures a smooth and accurate adjustment process. Overall, the environmentally friendly sound insulation device of Example 2 is superior to Example 1 in all aspects and has higher practical value and promotion significance.

[0095] The above are only preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be regarded as excluding other embodiments. Instead, it can be used in various other combinations, modifications and environments, and can be modified within the scope of the conception of this article through the above teachings or technology or knowledge in related fields. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention and should all be within the scope of protection of the claims attached to the present invention.
