The sound barriers are generally arranged on two sides of a road and are mainly used for attenuating noise of a railway, a highway or an industrial factory, so that the effect of reducing the noise is achieved. Fig. 1 to 7 are schematic structural views of a sound barrier according to this embodiment. As shown in fig. 1 to 7, the sound barrier includes a fixed frame 1, a soundproof plate 2, a detecting unit 3, a data collecting module 4, and a data processing terminal 5. Wherein, fixed frame 1 and base thing fixed connection, acoustic celotex board 2 setting are installed between two adjacent fixed frames 1, and acoustic celotex board 2 is used for absorbing noise reduction. The detecting unit 3 is fixed at a side of the soundproof plate 2 for detecting a distance between the soundproof plate 2 and the fixed frame 1. The data acquisition module 4 is connected with the plurality of detection units 3 through wires and is used for acquiring distance signals measured by the detection units. The data processing terminal 5 is in communication connection with the data acquisition module 4, and is used for receiving the distance information obtained by the data acquisition module 4, and judging the safety state of the corresponding sound insulation board 2 according to the distance signal, so as to prompt a worker to overhaul or replace the sound insulation board 2 in time.
In this embodiment, the fixing frame 1 is an H-shaped upright, that is, the fixing frame 1 includes two limiting grooves 11 with opposite openings. The thickness of the sound insulation plate 2 is matched with the width of the limiting groove 11, and the sound insulation plate 2 is clamped in the limiting grooves 11 of the two adjacent fixed frames 1, as shown in fig. 1. The H-shaped upright column means that the fixed frame 1 comprises two first limiting plates 14 and two second limiting plates 15. The two first limiting plates 14 are disposed parallel to each other, and the second limiting plate 15 is disposed between the two first limiting plates 14 in a manner perpendicular to the first limiting plates 14. The second limiting plate 15 and the two first limiting plates 14 form two limiting grooves 11 with opposite openings. The two sides of the sound insulation plate 2 are respectively fixed in the limit grooves 11 corresponding to the fixed frames 1. In actual installation, a space is formed between two sides of the sound insulation plate 2 and the second limiting plate 15 of the limiting groove 11. In the actual detection process, the detection units 3 disposed on two sides of the acoustic panel 2 are used for detecting the distance from the side edge of the acoustic panel 2 to the second limiting plate 15.
The bottom of the fixed frame 1 is also provided with a fixed connection 12. The fixed connection 12 may be connected to the fixed frame 1 by welding or the like. In this embodiment, the fixing connection portion 12 may be configured as a steel plate, and may be fixedly connected with the base by a bolt, and the like, so as to fix the fixing frame 1 and the base. Preferably, the sound barrier further includes a sealing unit 6 disposed between the fixing frame 1 and the soundproof plate 2 for sealing a gap between the fixing frame 1 and the soundproof plate 2. In this embodiment, the sealing unit 6 may be a single tube adhesive tape, a nylon adhesive tape, or the like.
The left and right ends of the sound insulation plate 2 are clamped in the limit grooves 11 of the fixed frame 1, and a space is formed between the left and right side surfaces of the sound insulation plate 2 and the bottom surfaces (namely the second limit plates 15) of the limit grooves 11 of the corresponding fixed frame 1. The plurality of detection units 3 are provided on the left and right opposite side surfaces of the soundproof plate 2, respectively, whereby the distance between the side surface of the soundproof plate 2 and the second limiting plate 15 of the fixed frame 1 can be detected. In this embodiment, the detection unit 3 may be an infrared ranging sensor. The infrared ranging sensor is provided with a pair of infrared signal emitting and receiving diodes, the infrared ranging sensor emits a beam of infrared light, a reflecting process is formed after the infrared ranging sensor irradiates the second limiting plate 15, signals are received after the infrared ranging sensor reflects the infrared ranging sensor, and the distance from the infrared ranging sensor to the second limiting plate 15 is calculated by processing time difference data of the emission and the receiving. In the present embodiment, the plurality of detecting units 3 may be disposed at the side of the soundproof plate 2 in a longitudinally aligned manner. Wherein the distances between adjacent detection units 3 may be equal or unequal.
The detection unit 3 transmits the acquired distance signals to the data processing terminal 5 in a wireless or wired mode through the data acquisition module 4 for safety judgment. When the data processing terminal 5 determines that the distance from the detection unit 3 to the bottom surface (the second limiting plate 15) of the limiting groove 11 exceeds the preset safety value, the data processing terminal 5 can timely inform relevant staff to repair or replace the corresponding sound insulation plate 2. In this embodiment, each detection unit 3 has a corresponding unique number, and when the detection unit 3 sends a distance signal to the data processing terminal 5 through the data acquisition module 4, the distance signal includes the unique number of the detection unit 3, so that the data processing terminal 5 can specifically obtain the security state of the acoustic panel 2 at the corresponding position when analyzing the distance signal.
Preferably, the sound barrier further comprises alarm means connected to the data processing terminal 5. When the data processing terminal 5 judges that the distance from the detection unit 3 to the bottom surface (the second limiting plate 15) of the limiting groove 11 exceeds a preset safety value, the data processing terminal 5 controls the alarm device to start to alarm, so that maintenance personnel can be informed of timely processing, and safe use of the sound barrier is guaranteed.
In this embodiment, two sides of the limiting groove 11 (i.e. the first limiting plate 14) in the fixed frame 1 are respectively provided with a limiting hole 13. Wherein, the position of the limiting hole 13 is close to the edge of the fixed frame 1, as shown in fig. 2. Correspondingly, the front and rear sides of the sound insulation board 2 are also provided with a limiting component 21, as shown in fig. 5. When the acoustic panel 2 is mounted in two adjacent fixed frames 1, the height of the limiting hole 13 is the same as the height of the limiting member 21 on the acoustic panel 2, that is, the limiting hole 13 and the limiting member 21 are positioned at the same horizontal position, as shown in fig. 2.
In the first state, i.e., when the baffle plate 2 is initially installed in the limit groove 11 of the fixed frame 1, the limit member 21 is located inside the limit hole 13, and the limit member 21 is in a compressed state by compression between the side surface of the limit groove 11 (the first limit plate 14) and the side surface of the baffle plate 2. When the acoustic baffle plate 2 is bent and deformed, the two ends of the acoustic baffle plate 2 and the fixed frame 1 move transversely relatively, namely, when the acoustic baffle plate 2 has a trend of moving out of the fixed frame 1, at the moment, when the acoustic baffle plate 2 moves continuously, the limiting part 21 does not receive the pressure of the fixed frame 1 any more when the limiting part 21 moves to the position where the limiting hole 13 is located, and the acoustic baffle plate 2 extends out of the corresponding limiting hole 13 after stretching according to the elasticity of the acoustic baffle plate 2, so that the acoustic baffle plate 2 is limited to move continuously. At this time, the baffle plate 2 is fixedly connected with the fixed frame 1 through the limiting component 21 and the limiting hole 13, so that the baffle plate 2 can be prevented from moving continuously, and potential safety hazards are generated. Preferably, the limiting member 21 may be a spring pin. The limiting hole 13 may be a rectangular hole, and when the sound insulation board 2 moves outwards to generate a longitudinal offset, the limiting component 21 may still be stretched to be connected with the limiting hole 13.
In this embodiment, the soundproof panel 2 includes a soundproof frame 22, a soundproof back plate 23, a soundproof face plate 24, and sound absorbing cotton 25, as shown in fig. 4. The sound insulation back plate 23 is disposed on one side of the sound insulation frame 22, and the sound insulation face plate 24 is disposed on the other side of the sound insulation frame 22 opposite to the sound insulation back plate 23. The sound insulation panel 24, the sound insulation back plate 23 and the sound insulation frame 22 enclose a receiving space, and the sound absorption cotton 25 is filled in the receiving space for absorbing noise. The soundproof panel 24 has a plurality of sound absorbing holes 241 as shown in fig. 2 and 5. When the sound insulation board 2 is installed in the fixed frame 1, one side where the sound insulation panel 24 is arranged is installed on one side where noise is generated, the noise enters the sound insulation board 2 through the sound absorption holes 241 on the sound insulation panel 24, and the sound is absorbed through the sound absorption cotton 25, so that the decibel of the noise is reduced.
In this embodiment, the opposite sides of the soundproof frame 22 are provided with grooves 221, respectively, that is, both sides of the soundproof frame 22 fixedly installed with the fixing frame 1. A plurality of detection units 3 are fixed in the recess 221 as shown in fig. 2 and 3. The grooves 221 on both sides of the sound insulation frame 22 can increase the distance between the detection unit 3 and the second limiting plate 15 of the fixed frame 1, so that the distance signal between the sound insulation plate 2 and the fixed frame 1 can be better detected through the detection unit 3. The sound absorbing cotton 25 may be made of foamed aluminum material with good sound absorbing effect, the sound insulation back plate 23 may be an acrylic plate with good light transmittance, and the sound insulation panel 24 may be a punched galvanized plate. The soundproof rear plate 23 and the soundproof front plate 24 are fastened to the soundproof frame 22 by bolts, respectively. Preferably, the materials of the sound insulation frame 22, the sound insulation back plate 23 and the sound insulation panel 24 can be aluminum alloy, so that the integral quality of the sound insulation panel 2 can be reduced, the light production and transportation are realized, and the installation efficiency is improved.
In this embodiment, the data acquisition module 4 may be disposed outside the soundproof plate 2 or outside the fixing frame 1. Each data acquisition module 4 may be wired to a plurality of detection units 3. Specifically, a wiring groove is further provided in the sound insulation frame 22, and the wires of the detection unit 3 may be routed along the wiring groove in the sound insulation frame 22 and then connected with the data acquisition module 4. Correspondingly, the data processing terminal 5 may be communicatively connected to each data acquisition module 4 by wireless or wired means for acquiring and processing the distance signals. When the data processing terminal 5 is connected with the data acquisition module 4 in a wired mode, wiring holes can be further formed in the side edge of the sound insulation frame 22 and the second limiting plate 15, and connecting wires between the data acquisition module 4 and the data processing terminal 5 can be wired through wiring grooves in the sound insulation frame 22 and wiring holes in the side edge of the sound insulation frame 22 and the side edge of the second limiting plate 15, so that the overall attractiveness of the sound barrier can be improved, meanwhile, the wires can be prevented from being damaged manually, and the use of the sound barrier monitoring function is affected.
In another alternative implementation, to facilitate the production and transportation of the baffle 2, the baffle 2 is generally provided in a fixed-size configuration. In order to improve the sound insulation effect of the sound barrier, the height of the sound barrier may be increased continuously, so that sound waves can be diffracted only from above the sound insulation plate 2, thereby achieving the effect of reducing noise. At this time, the fixing frames 1 having a higher height may be selected to be fixed on the base, and then the plurality of sound insulation boards 2 are sequentially installed between the adjacent two fixing frames 1 in the order from bottom to top to form a complete sound barrier, as shown in fig. 2. The adjacent sound insulation plates 2 can be reinforced by adhesive strips and the like. Correspondingly, the fixed frame 1 is provided with a plurality of limiting holes 13 in the height direction. The height of the limiting holes 13 corresponds to the limiting parts 21 of the sound insulation plates 2 with the corresponding heights, so that the corresponding sound insulation plates 2 can be prevented from directly flying out of the fixed frame 1.
The sound barrier of the embodiment can be used in the fields of railway, highway and urban rail transit and is used for testing and monitoring deformation and the like of the sound insulation plate caused by additional load generated by impact load and temperature change. Because the pulse load that produces when the train passes through acts on the acoustic celotex board, the acoustic celotex board produces the vibration, and acoustic celotex board and acoustic celotex backplate produce bending deformation, along with the continuous increase of pulse load number of times, the bending deformation volume of acoustic celotex board increases, and the acoustic celotex board can follow fixed frame in when serious and drop and fly out, seriously influences train driving safety. The detection units for detecting distance signals from the side edges of the sound insulation plate to the fixed frame are arranged on two sides of the sound insulation plate. The detection unit 3 transmits the acquired distance signals to the data processing terminal 5 in a wireless or wired mode through the data acquisition module 4 for safety judgment. When the data processing terminal 5 judges that the distance from the detection unit 3 to the bottom surface of the limit groove 11 exceeds the preset safety value, the data processing terminal 5 can timely inform relevant staff to repair or replace the corresponding sound insulation plate 2, so that the safety use of the sound barrier is ensured.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art.
