Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a sound insulation and noise reduction partition wall system according to an embodiment of the present invention includes an annular inner partition wall 1, an annular outer partition wall 2, a first noise reduction system 3, and a second noise reduction system 4. The inner partition wall 1 is positioned at the inner side of the outer partition wall 2, and the inner partition wall 1 and the outer partition wall 2 are concentrically arranged. The first noise reduction system 3 is connected with the inner wall of the inner partition wall 1, and the second noise reduction system 4 is connected with the inner wall of the outer partition wall 2.
In the working process of the embodiment, the inner partition wall 1 and the outer partition wall 2 are built on the periphery of a construction site by taking the construction site as a center. The inner partition wall 1 and the outer partition wall 2 are both circular. The construction position is located at the circle center. The noise frequency of the noise emitted by the construction site reaching each point on the same horizontal ring on the inner wall of the inner partition wall 1 is the same. The noise frequencies of all points which pass through the inner partition wall 1 and reach the same horizontal ring on the inner wall of the outer partition wall 2 are the same. And connecting the first noise reduction system 3 with the inner wall of the inner partition wall 1, and performing noise reduction treatment on noise in the inner partition wall 1. The second noise reduction system 4 is connected to the inner wall of the outer partition wall 2 to reduce noise transmitted between the inner partition wall 1 and the outer partition wall 2. By arranging the inner partition wall 1, the outer partition wall 2, the first noise reduction system 3 and the second noise reduction system 4, the noise at the construction site can be reduced.
Preferably, the first noise reduction system 3 comprises a first controller 301 and a first noise reduction unit. The first noise reduction unit includes one first sound sensor 302 and an even number of first sound generators 303. The first sound sensor 302 and the first sound generator 303 are both fixedly connected to the inner wall of the inner partition wall 1, and the first sound sensor 302 and the first sound generator 303 are circumferentially arranged and located on the same horizontal ring. The first sound sensor 302 and the first sound generator 303 are connected to the first controller 301, respectively. The first acoustic emitters 303 are symmetrically arranged around the center of the horizontal circle.
When the first noise reduction system 3 is in operation, the first sound sensor 302 collects noise information and transmits the noise information to the first controller 301. The first controller 301 obtains the sound emission information, such as the sound emission frequency, of the first sound emitter 303 through calculation based on the noise information, and controls the first sound emitter 303 to emit sound based on the sound emission information. Since the noise frequencies of all points on the same horizontal plane of the inner wall of the inner partition wall 1 are the same, noise information, such as the sound frequency, can be collected by arranging a first sound sensor 302. In the same first noise reduction unit, the first acoustic sensor 302 and the first acoustic generator 303 are circumferentially arranged and located on the same horizontal ring. According to the noise frequency collected by the first sound sensor 302, the first controller 301 makes the first sound generators 303 belonging to the same first noise reduction unit emit sounds with the same frequency to the center of the circle. The noise emitted by the construction site is eliminated by using the reverse sound with the same frequency. The first acoustic emitters 303 are symmetrically arranged around the center of the horizontal circle. In this way, the unnecessary sound after the first sound generator 303 and the construction site noise are cancelled out with the unnecessary sound after the first sound generator 303 and the construction site noise are cancelled out. This prevents or reduces the sound emitted by the first sound emitter 303 from passing out of the inner partition wall 1, reducing noise.
Preferably, the number of the first noise reduction units is N, and the N first noise reduction units are longitudinally arranged along the inner wall of the inner partition wall; n is an integer greater than 1. The N first noise reduction units are arranged on the inner wall of the inner partition wall 1 from top to bottom. The arrangement of the plurality of first noise reduction units is beneficial to eliminating construction site noise as much as possible in the inner partition wall 1.
Preferably, in the N first noise reduction units, the sound sensors in two adjacent first noise reduction units are arranged in a staggered manner. Because the noise information of the construction site noise reaching different heights of the inner partition wall 1 is different, the sound sensors in different first noise reduction units are arranged in a staggered mode, and the data measured by the sound sensors are more accurate.
Preferably, the second noise reduction system 4 comprises a second controller 401 and a second noise reduction unit. The second noise reduction unit comprises one second sound sensor 402 and an even number of second sounders 403. The second sound sensor 402 and the second sounder 403 are respectively fixedly connected to the inner wall of the outer partition wall 2. The second sounder 403 and the second sound sensor 402 are arranged along the circumferential direction and are located on the same horizontal ring. The second sound sensor 402 and the second sounder 403 are respectively connected to the second controller 401.
The construction site noise that cannot be eliminated by the first noise reduction system 3 is eliminated by the second noise reduction system 4. When construction site noise passes through the inner partition wall 1 and enters between the inner partition wall 1 and the outer partition wall 2, the noise is eliminated by using the second noise reduction system 4. Specifically, the second sound sensor 402 is fixedly attached to the inner wall of the outer partition wall 2. The second sound sensor 402 is used to collect the noise information transmitted from the inner partition wall 1 and transmit the information to the second controller 401. The second controller 401 obtains the sound emission information, such as the sound emission frequency, of the second sound generator 403 through calculation according to the noise information, and controls the second sound generator 403 to emit sound according to the sound emission information. Since the noise frequencies of the points on the same horizontal plane on the inner wall of the outer partition wall 2 are the same, noise information, such as the sound emission frequency, can be collected by providing a second sound sensor 402. In the same second noise reduction unit, the second sounders 403 are fixedly connected to the inner wall of the outer partition wall 2, arranged along the circumferential direction, and located on the same horizontal ring. In the same second noise reduction unit, the second sounder 403 and the second controller 401 are located on the same horizontal ring. According to the noise frequency collected by the second sound sensor 402, the second controller 401 makes the second sound generators 403 belonging to the same second noise reduction unit emit sounds with the same frequency to the center of the circle. The noise coming out of the inner partition wall 1 is eliminated by the reverse sound of the same frequency. In this way, noise between the inner partition wall 1 and the outer partition wall 2 is eliminated by the second noise reduction system 4.
Preferably, the second sounder 403 is arranged symmetrically about the centre of the outer partition wall 2. The redundant sound generated after the second sound generator 403 and the noise transmitted from the inner partition wall 1 are offset with the redundant sound generated after the second sound generator 403 and the noise transmitted from the inner partition wall 1 are oppositely arranged. In this process, the second sound generator 403 and the noise transmitted from the internal partition wall 1 cancel the excessive sound, and pass through the internal partition wall 1 through the elimination portion of the internal partition wall 1. The sound emitted by the oppositely arranged second sound generators 403 cancel each other out inside the inner partition wall 1. This prevents or reduces the sound emitted by the second sound generator 403 from being transmitted out of the outer partition wall 2, reducing noise.
Preferably, the height of the inner partition wall 1 is smaller than that of the outer partition wall 2. The height of the outer partition wall 2 is greater than that of the inner partition wall 1, and the part of the outer partition wall 2 which is higher than the inner partition wall can isolate the noise penetrating out of the top of the inner partition wall 1. Preferably, the inner wall of the upper part of the outer partition wall 2 is provided with a sound-absorbing plate. The noise reduction plate can absorb noise. The inner wall of the upper part of the outer partition wall 2 is provided with a sound-absorbing board which absorbs the noise penetrating out from the top of the inner partition wall 1 and reduces the noise to be transmitted out of the outer partition wall 2.
Preferably, the top end of the outer partition wall 2 is provided with an annular green planting area. Green leaf plants are planted in the green planting areas. The green leaf plants were used to absorb some of the noise. The green planting area is annularly arranged along the top end of the outer partition wall 2. Since the height of the outer partition wall 2 is higher than that of the inner partition wall 1, the top end of the outer partition wall 2 is more susceptible to the action of external wind. The green leaf plants are blown by wind and swing. This facilitates noise reduction of the green leaves from different positions.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is also intended to be covered by the appended claims. The scope of the invention is defined by the claims and their equivalents.
