[0001] The utility model relates to the technical field of noise control, in particular to a noise control shielding device. Background Art

[0002] Noise is the sound with irregular and disorderly changes in the frequency and intensity of sound waves. From a physiological perspective, any sound that interferes with people's rest, study, and work and the sound that people want to hear is an unwanted sound, collectively referred to as noise. When noise has an adverse impact on people and the surrounding environment, it forms noise pollution.

[0003] Vehicles running on the road often generate noise, which will affect the residents living near the road. Therefore, it is necessary to install noise control shielding devices on both sides of the road. The existing noise control shielding devices are composed of multiple sound insulation boards or sound absorption boards, which results in certain gaps between the boards and a certain distance between the boards and the ground, causing noise to pass through these gaps, thereby affecting the residents living near the road.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1-4, a noise control and shielding device, including a mounting frame 1. A connecting frame 2 is fixedly arranged on the right side of the mounting frame 1, and a connecting block 4 is fixedly arranged on the left side of the mounting frame 1. A first threaded hole 5 is formed on the surface of the connecting frame 2, and a second threaded hole 6 is formed on the surface of the connecting block 4. By sequentially rotating a bolt into the first threaded hole 5 and the second threaded hole 6, the connecting block 4 of one mounting frame 1 and the connecting frame 2 of another mounting frame 1 can be fixed. A sound insulation cotton 3 is fixedly arranged inside the connecting frame 2. A bottom frame 7 is fixedly arranged at the bottom of the mounting frame 1. A first elastic member 8 is arranged inside the bottom frame 7. The first elastic member 8 is a spring. One end of the first elastic member 8 is fixedly connected to the inside of the bottom frame 7, and the other end of the first elastic member 8 is fixedly connected to the top of the bottom block 9. When the bottom block 9 is squeezed upward by the ground, the first elastic member 8 will be compressed. Through the rebound of the first elastic member 8, the bottom block 9 is made to press against the ground, so that there is no gap between the ground and the bottom block 9. A bottom block 9 is movably arranged inside the bottom frame 7. A sound insulation component is arranged inside the mounting frame 1. The sound insulation component includes a first sound absorption hole plate 14 fixedly arranged inside the mounting frame 1. A sound reflection plate 15 is fixedly arranged at the rear of the first sound absorption hole plate 14. A second sound absorption hole plate 16 is fixedly arranged inside the mounting frame 1. The second sound absorption hole plate 16 and the sound reflection plate 15 do not contact. A sound absorption cotton 17 is fixedly arranged at the rear of the second sound absorption hole plate 16. When the noise passes through the first sound absorption hole plate 14, part of the sound is absorbed. The unabsorbed sound is reflected by the sound reflection plate 15 for a part. The sound not reflected by the sound reflection plate 15 will be transmitted into the second sound absorption hole plate 16, and finally the noise not absorbed by the second sound absorption hole plate 16 is absorbed by the sound absorption cotton 17, improving the blocking effect on the noise. A buffer component is arranged on the front side of the mounting frame 1. A ground nail 10 is fixedly arranged at the bottom of the mounting frame 1. The number of the ground nails 10 is multiple. The mounting frame 1 can be fixed on the ground through the ground nails 10. For this noise control and shielding device, the connecting block 4 on the left side of one mounting frame 1 is inserted into the connecting frame 2 on the right side of another mounting frame 1, so that the connecting block 4 presses against the sound insulation cotton 3 inside the connecting frame 2, and the connecting block 4 and the connecting frame 2 are fixed, so that the two mounting frames 1 are fixed. When the noise passes through the gap between the connecting block 4 and the connecting frame 2, the sound is blocked by the sound insulation cotton 3. At the same time, when the mounting frame 1 is fixed by the fixed ground nails 10, as the ground nails 10 enter the ground, the ground pushes the bottom block 9 upward to move, compressing the first elastic member 8. Through the rebound effect of the first elastic member 8, the bottom block 9 is pushed downward to move, and thus the bottom block 9 presses against the ground. This device blocks the gaps existing during installation, preventing the noise from being transmitted to the residential area through the gaps, and improving the blocking effect of the device on the noise.

[0021] Specifically, the buffer assembly includes a fixing frame 11 fixedly arranged on the front side of the mounting frame 1. A second elastic member 13 is arranged inside the fixing frame 11. The second elastic member 13 is a spring. One end of the second elastic member 13 is fixedly connected to the inside of the fixing frame 11, and the other end of the second elastic member 13 is fixedly connected to the rear side of the buffer plate 12. The buffer plate 12 is movably arranged inside the fixing frame 11. When an object impacts the buffer plate 12, the buffer plate 12 moves and compresses the second elastic member 13. Through the rebounding effect of the second elastic member 13, the buffer plate 12 is pushed to move in the other direction, thereby weakening the impact force received by the mounting frame 1 and protecting the mounting frame 1.

[0022] During use: Insert the connecting block 4 on the left side of one mounting frame 1 into the connecting frame 2 on the right side of another mounting frame 1, so that the connecting block 4 abuts against the sound insulation cotton 3 inside the connecting frame 2. Then, rotate the bolt into the first threaded hole 5 and the second threaded hole 6 to fix the connecting block 4 and the connecting frame 2, so that the two mounting frames 1 are fixed. At the same time, when the mounting frame 1 is fixed by the fixing spike 10, as the fixing spike 10 enters the ground, the ground and the pushing base block 9 move upward, compressing the first elastic member 8. Through the rebounding effect of the first elastic member 8, the base block 9 is pushed to move downward, so that the base block 9 abuts against the ground. When the noise generated on the road propagates, a part of the sound is absorbed by the first sound absorption hole plate 14. The sound that is not absorbed is reflected by the sound reflection plate 15 for a part. The sound that is not reflected by the sound reflection plate 15 will be transmitted into the second sound absorption hole plate 16, and finally the noise that is not absorbed by the second sound absorption hole plate 16 is absorbed by the sound absorption cotton 17.

[0023] In summary, for this noise control and shielding device, insert the connecting block 4 on the left side of one mounting frame 1 into the connecting frame 2 on the right side of another mounting frame 1, so that the connecting block 4 abuts against the sound insulation cotton 3 inside the connecting frame 2, and fix the connecting block 4 and the connecting frame 2, so that the two mounting frames 1 are fixed. When the noise passes through the gap between the connecting block 4 and the connecting frame 2, the sound is blocked by the sound insulation cotton 3. At the same time, when the mounting frame 1 is fixed by the fixing spike 10, as the fixing spike 10 enters the ground, the ground and the pushing base block 9 move upward, compressing the first elastic member 8. Through the rebounding effect of the first elastic member 8, the base block 9 is pushed to move downward, so that the base block 9 abuts against the ground. This device blocks the existing gaps during installation, preventing noise from being transmitted to the residential area through the gaps, and improving the noise blocking effect of the device.
