[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a municipal road sound absorption structure, including: a mounting plate 1, the top of the mounting plate 1 is fixedly connected to a first outer panel 2, the top of the mounting plate 1 is fixedly connected to a second outer panel 3 at a position close to the rear surface of the first outer panel 2, and the tops of the first outer panel 2 and the second outer panel 3 are both fixedly connected to a rebound top plate 7; an extension component 4, the extension component 4 is fixedly connected to the inner surface of the first outer panel 2, the extension component 4 includes a connecting frame 401 and a baffle 408; a mounting component 5, the mounting component 5 is fixedly connected to the inner bottom surfaces of the first outer panel 2 and the second outer panel 3, the mounting component 5 includes a fixing seat 501, the connecting frame 401 is fixedly connected to the inner surface of the first outer panel 2, the front surface of the connecting frame 401 and the front surface of the baffle 408 are rotatably connected by a hinge, the front surface of the baffle 408 is evenly provided with a plurality of sound absorbing holes 409, and the inner surface of the connecting frame 401 is symmetrically fixed. A first fixed block 402 is fixedly connected, and the outer surfaces of the two first fixed blocks 402 are rotatably connected to the first connecting blocks 403 respectively. Electric telescopic rods 404 are respectively arranged on the tops of the two first connecting blocks 403, and second connecting blocks 406 are respectively arranged on the output ends of the two electric telescopic rods 404. The inner walls of the two second connecting blocks 406 are respectively rotatably connected to the second fixed blocks 407, and the front surfaces of the two second fixed blocks 407 are fixedly connected to the rear surface of the baffle 408. The fixing seat 501 is fixedly connected to the inner bottom surfaces of the first outer plate 2 and the second outer plate 3. A plurality of fixed shafts 502 are equidistantly fixedly connected to the top of the fixing seat 501, and the outer surfaces of the plurality of fixed shafts 502 are respectively rotatably connected to the rotating blocks 503, and the outer surfaces of the plurality of rotating blocks 503 are respectively rotatably connected to the bearing blocks 504, and the tops of the plurality of bearing blocks 504 are fixedly connected to the mounting frames 505.

[0025] The effect achieved by the entire embodiment 1 is that when installing the sound-absorbing structure, it is necessary to cooperate with multiple municipal road sound-absorbing structures to make multiple sound-absorbing structures connected end to end and installed on both sides of the road. First, use tools to fix the installation plate 1 on the guardrail or the pre-buried anchor bolt of the road, and fix the first outer panel 2 and the second outer panel 3 on the top of the installation plate 1 respectively, so that a silencer cavity is formed between the first outer panel 2 and the second outer panel 3, and the sound on the road surface will pass through the multiple sound-absorbing holes 409 evenly opened on the surface of the baffle 408. The noise entering the silencer cavity will be absorbed by the silencer plate 506. The silencer plate 506 is made of materials such as foam plastic or expanded perlite, and has multiple tiny micropores evenly opened on the surface. The tiny micropores will absorb the noise. The noise entering from the sound-absorbing holes 409 will continue to be weakened under the action of the silencer plate 506. Under the shielding effect of the composite membrane layer 6 and the second outer panel 3, the noise transmitted to the residential area is extremely small. When the silencer plate 506 needs to be cleaned or replaced for maintenance, it is started synchronously. The two electric telescopic rods 404 are moved. When the output ends of the two electric telescopic rods 404 are extended, the outer surfaces of the first fixed block 402 and the second fixed block 407 corresponding to the first connecting block 403 and the second connecting block 406 will rotate. At the same time, the positions of the two electric telescopic rods 404 will change from a vertical state to an inclination to one side, so that the baffle 408 will rotate open with the hinge as the axis, so that the structural components in the silencer cavity will be exposed to the personnel, and then the pull rod set on one side of the front surface of the installation frame 505 is held and pulled outward, and the multiple bearing blocks 504 will rotate correspondingly on the top outer surfaces of the multiple rotating blocks 503. The multiple rotating blocks 503 will also rotate on the outer surfaces of the multiple fixed shafts 502 set on the top of the fixed seat 501 at the same time, and the multiple rotating blocks 503 will rotate with the corresponding fixed shafts 502 as the axis, so that the installation frame 505 will be moved out of the silencer cavity, which is convenient for personnel to clean or disassemble and maintain the silencer plate 506 set on its inner surface, thereby reducing the maintenance difficulty of the municipal road sound absorption structure.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, a silencer plate 506 is arranged on the inner surface of the installation frame 505, and the outer surfaces on both sides of the installation frame 505 are respectively fixedly connected with limit blocks 509, through holes are respectively opened on the tops of the two limit blocks 509, and latches 508 are respectively arranged in the through holes of the two limit blocks 509, and fixing holes 507 are symmetrically opened on the top of the fixing seat 501, and the through holes of the limit blocks 509 correspond to the positions of the fixing holes 507, and the outer surface of the latch 508 is slidably connected with the inner surface of the fixing hole 507, and a plurality of fine micropores are evenly opened on the front surface of the silencer plate 506, and a composite film layer 6 is arranged on the inner surface of the second outer plate 3, and the composite film layer 6 is matched with the silencer plate 506.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, by respectively arranging two limit blocks 509 on the outer surface of the installation frame 505, the silencer 506 can be reset under the rotation of the multiple rotating blocks 503 after cleaning or replacement. After the through holes of the two limit blocks 509 are aligned with the positions of the two fixing holes 507, the two corresponding latches 508 are held and inserted into the through holes and the fixing holes 507 accordingly, which plays a role in limiting the installation frame 505. A composite film layer 6 is provided on the rear surface of the silencer 506. The composite film layer 6 is generally made of plastic film, canvas, artificial leather and other materials, which can effectively resonate with medium and low frequency noise sound waves, thereby achieving the effect of eliminating medium and low frequency noise. The composite film layer 6 and the second outer panel 3 shield the noise and reduce the noise transmitted to the residential area. At the same time, an inclined rebound top plate 7 is arranged on the top of the first outer panel 2 and the second outer panel 3. The rebound top plate 7 will block the noise on the top, so that part of the noise will be rebounded downward, effectively reducing the noise transmission on the side above the road.

[0028] Working principle: When in use, the two electric telescopic rods 404 are started synchronously. When the output ends of the two electric telescopic rods 404 are extended, the outer surfaces of the first fixing block 402 and the second fixing block 407 corresponding to the first connecting block 403 and the second connecting block 406 are rotated. At the same time, the positions of the two electric telescopic rods 404 are changed from a vertical state to a tilt to one side, so that the baffle 408 is rotated and opened with the hinge as the axis, so that the structural components in the silencer cavity are exposed to the personnel, and then the pull rod set on one side of the front surface of the installation frame 505 is held and pulled outwards. The multiple supporting blocks 504 will rotate correspondingly on the top outer surfaces of the multiple rotating blocks 503, and the multiple rotating blocks 503 will also rotate on the outer surfaces of the multiple fixed shafts 502 set on the top of the fixed seat 501. The multiple rotating blocks 503 will rotate around the corresponding fixed shafts 502, so that the installation frame 505 will be moved out of the silencer cavity, which is convenient for personnel to clean or disassemble and maintain the silencer plate 506 set on its inner surface, prevent floating dust on the road from clogging the holes on the surface of the silencer plate 506, affecting the use of the silencer plate 506, and improving the maintenance effect of the municipal road sound absorption structure.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
