Description

Technical Field

[0001] This invention relates to the field of noise monitoring technology, specifically to a noise monitoring device for road environments. Background Technology

[0002] A noise monitor is an instrument used to check noise levels. When in use, a sound-absorbing sponge is placed over the monitor to measure the decibel value of indoor and outdoor noise. Traffic intersections or roads with heavy traffic are noisier and cause inconvenience to people's lives. Therefore, it is necessary to monitor road noise in real time and take corresponding traffic control measures to ensure a good living environment.

[0003] Road noise monitoring devices are typically installed on both sides of the road and monitor noise levels. To ensure the sound reception of the noise monitor, a sponge sleeve is usually installed on its surface to reduce wind noise and stabilize sound reception. When multiple vehicles are traveling on the road in windy weather, the vehicles will stir up dust on the road, and the wind will easily blow the dust onto the surface of the sponge sleeve. Over time, this can cause blockage on the surface of the sponge sleeve, affecting the intensity of road noise detection and reducing the detection effect and accuracy of the noise monitor. Summary of the Invention

[0038] Several rubber strips are provided on the side of the touch panel away from the starter plate, and these rubber strips are distributed circumferentially around the fixed rod.

[0039] The present invention has the following beneficial effects:

[0040] 1. In this invention, the moving plate pushes the exhaust plate to move synchronously and blows air through the sponge sleeve on the surface of the noise meter. At this time, the pushed air blows away the dust attached to the surface of the sponge sleeve. Since the strong wind outside will carry away the blown-away dust, the dust will not fall back onto the surface of the sponge sleeve and affect the effect of road noise collection and detection. Due to the setting of the moving plate, the noise meter can blow away the dust that usually accumulates on the surface of the sponge sleeve from the inside to the outside on windy days, completing self-cleaning. This reduces the impact of clogging on the surface of the sponge sleeve on the intensity of road noise detection, thereby improving the detection effect and accuracy of the noise monitoring instrument.

[0041] 2. In this invention, when the wind blows from the left, it is first guided by the guide groove on the right side of the synchronization plate and blows towards the synchronization plate, thereby pushing the synchronization plate closer to the starting plate. This causes the rubber plate to form a windbreak on the side near the starting plate, thereby causing the starting plate and the synchronization plate to rotate. This improves the smoothness of the movement of the moving plate under different wind directions. Due to the setting of the guide groove, the turbulence generated in the internal space of the main body when the wind blows from the left or right is reduced, which may prevent the starting plate and the synchronization plate from rotating. This further improves the smoothness of the starting plate's rotation in the face of different wind directions.

[0042] 3. In this invention, the sliding plate at the bottom of the rotating plate moves toward the rubber plate, and the touch plate of the bottom sliding plate also guides the deformation direction of the rubber plate, so that the deformation direction of the rubber plate remains consistent when the synchronous plate moves toward the starting plate. Because the rotating plate is designed to reduce the situation where the rubber plate deformation direction is inconsistent due to the shaking caused by the starting plate being pushed by the wind, the consistency of the rubber plate deformation direction is further improved when the starting plate or the synchronous plate is pushed.

[0043] 4. In this invention, the rubber strip deforms and forms friction with the outer surface of the fixed rod. When the starting plate and the synchronous plate rotate, the friction between the rubber strip and the fixed rod slows down the rotation speed of the starting plate, thereby indirectly slowing down the rising and falling speed of the moving plate. Due to the setting of the guide plate, the deformation plate and the rubber strip, the situation where the moving plate moves up and down too fast and causes sound to be generated inside the cylinder is reduced, thereby further improving the accuracy of the noise meter in detecting road noise.

[0044] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0073] An anemometer 124 is installed on the left side of the wind vane 123. The bottom of the anemometer 124 is fixedly connected to the top of the main body 1. Then, monitoring devices such as camera 113, temperature and humidity sensor 114, noise meter 121, particle detector 122, wind vane 123, and anemometer 124 are installed on the top, bottom, and side walls of the main body 1.

[0074] The blowing assembly 21 includes a fixed rod 211 fixedly connected inside the main body 1. A starting plate 212 is sleeved on the outer surface of the fixed rod 211. A connecting rod 213 is fixedly connected to the side wall of the starting plate 212. A following block 214 is slidably connected to the outer surface of the connecting rod 213.

[0075] Two push rods 215 are fixedly connected to the top of the follower block 214, and the push rods 215 are symmetrically distributed with the starter plate 212 as the center.

[0076] A cylinder 216 is provided at the top of the push rod 215, and the bottom of the cylinder 216 is fixedly connected to the top of the main body 1;

[0077] The end of the cylinder 216 away from the main body 1 is in contact with the outer surface of the noise meter 121. The follower block 214 will drive the push rod 215 to move downward synchronously. The downward movement of the push rod 215 will drive the top moving plate 221 to move downward synchronously. When the moving plate 221 moves downward, it will contact the limiting post 224 and drive the limiting post 224 to move synchronously.

[0078] The pushing assembly 22 includes a movable plate 221 fixedly connected to the top of two pushing rods 215. The top of the movable plate 221 is provided with an exhaust plate 222, and the side wall of the movable plate 221 is slidably connected to the inner wall of the cylinder 216.

[0079] A guide plate 223 is fixedly connected to the top of the exhaust plate 222, and two limiting posts 224 are fixedly connected to the bottom of the exhaust plate 222. The two limiting posts 224 are symmetrically distributed with the noise meter 121 as the center.

[0080] The end of the limiting post 224 away from the exhaust plate 222 slides through to the bottom outer wall of the moving plate 221;

[0081] Several deformation plates 225 are fixedly connected to the bottom of the exhaust plate 222. The deformation plates 225 are distributed circumferentially around the moving plate 221. The movement of the limiting post 224 will drive the exhaust plate 222 to move downward. When the exhaust plate 222 moves downward, it will pull air into the interior of the cylinder 216 through the sponge sleeve outside the noise meter 121.

[0082] The rotating assembly 31 includes several guide grooves 311 formed inside the main body 1, and the several guide grooves 311 are symmetrically distributed in pairs around the starter plate 212.

[0083] The inner wall of the guide groove 311 is provided with an exhaust groove 312, and a synchronization plate 313 is provided between the two sets of exhaust grooves 312. The inside of the synchronization plate 313 is rotatably connected to the outer surface of the fixed rod 211.

[0084] A number of blocking strips 314 are fixedly connected to the side wall of the synchronization plate 313, and the blocking strips 314 are distributed circumferentially around the synchronization plate 313.

[0085] Several rubber plates 315 are provided on the left side of the blocking strip 314. The rubber plates 315 are distributed circumferentially around the starting plate 212. The sidewalls of the rubber plates 315 are fixedly connected to the sidewalls of the blocking strip 314. The side of the rubber plate 315 away from the blocking strip 314 is fixedly connected to the sidewall of the starting plate 212. The sliding of the starting plate 212 will cause the rubber plates 315 between the starting plate 212 and the synchronization plate 313 to deform. When the starting plate 212 and the synchronization plate 313 are in close contact, the top of the deformed rubber plate 315 will be bent by the blocking strip 314.

[0086] The guide assembly 32 includes a plurality of rotating plates 321 rotatably connected to the side wall of the starter plate 212. The plurality of rotating plates 321 are circumferentially distributed around the starter plate 212. Two sliding plates 322 are provided on the right side of the rotating plates 321. The two sliding plates 322 are symmetrically distributed around the rubber plate 315.

[0087] The side wall of the sliding plate 322 is slidably connected to the side wall of the rotating plate 321, and the top of the sliding plate 322 is fixedly connected to the top of the top of the sliding plate 322. The end of the elastic plate 323 away from the sliding plate 322 is fixedly connected to the side wall of the starting plate 212.

[0088] Two touch plates 324 are provided on the side of the elastic plate 323 away from the starting plate 212. The two touch plates 324 are symmetrically distributed with the rubber plate 315 as the center. The top of the touch plate 324 is fixedly connected to the bottom of the sliding plate 322.

[0089] Several rubber strips 325 are provided on the side of the touch plate 324 away from the start plate 212. The rubber strips 325 are distributed circumferentially around the fixed rod 211. When the rotating plate 321 rotates, the sliding plate 322 will rotate synchronously with the rotating plate 321. At this time, the touch plate 324 at the bottom of the sliding plate 322 will contact the rubber plate 315 first.

[0090] In use, the operator first fixes the main body 1 and the display screen 112 to the surface of the support column 111. Then, the monitoring devices, including the camera 113, temperature and humidity sensor 114, noise meter 121, particle detector 122, wind vane 123, and anemometer 124, are installed on the top, bottom, and side walls of the main body 1. The monitoring modules are then connected to the data processing and transmission device inside the main body 1 via wires. Finally, the support column 111 is erected and powered on, thus completing the assembly of the noise monitoring substation. The noise monitoring substation can collect raw environmental noise data in real time, calculate various evaluation parameters, and upload them to the server for intelligent analysis. Simultaneously, if the noise exceeds the standard, noise recording will be triggered, and the recording file will be automatically uploaded to the server. The deep learning algorithm model deployed on the cloud platform server can... The uploaded audio files are analyzed to identify the type of sound source that triggered the recording. Then, multiple sound sensors are used to construct a sound array to identify the largest sound source in the environment and control camera 113 to capture images in that direction. At the same time, alarm thresholds for exceeding environmental noise emission limits are set, and alarms are pushed to mobile terminals and cloud platforms along with the captured images when noise exceeds the limits, facilitating timely management of noise exceeding the limits. Based on long-term continuous noise data analysis, the daily noise pollution level is displayed on a calendar, including compliance status, number of exceedances, and year-on-year and month-on-month comparisons. This provides a basis for noise early warning and management and intuitively presents the daily noise pollution situation and trends in different areas, thus achieving the goal of noise monitoring on highways.

[0091] When the main body 1 encounters strong winds, the strong wind will cause the rubber plate 315 to rotate around the fixed rod 211. The rotation of the rubber plate 315 will cause the starting plate 212 to rotate synchronously. The rotation of the starting plate 212 will cause the connecting rod 213 to rotate synchronously. The rotation of the connecting rod 213 will cause the following block 214 to move up and down. When the following block 214 moves downward, it will cause the pushing rod 215 to move downward synchronously. The downward movement of the pushing rod 215 will cause the top moving plate 221 to move downward synchronously. When the moving plate 221 moves downward, it will contact the limiting post 224 and cause the limiting post 224 to move synchronously. The movement of the limiting post 224 will cause the exhaust plate 222 to move downward. When the exhaust plate 222 moves downward, it will draw air in through the sponge sleeve outside the noise meter 121. Inside the cylinder 216, when the follower block 214 moves upward, the moving plate 221 moves upward synchronously with the follower block 214. The moving plate 221 pushes the exhaust plate 222 to move synchronously and blows air out through the sponge sleeve on the surface of the noise meter 121. At this time, the expelled air blows the dust attached to the surface of the sponge sleeve away. Since the strong wind outside will carry away the blown dust, the dust will not fall back onto the surface of the sponge sleeve and thus affect the effect of road noise collection and detection. Due to the setting of the moving plate 221, the noise meter 121 can blow off the dust that usually accumulates on the surface of the sponge sleeve from the inside to the outside on windy days, completing self-cleaning. This reduces the impact of clogging on the surface of the sponge sleeve on the intensity of road noise detection, thereby improving the detection effect and accuracy of the noise monitoring instrument.

[0092] When a strong wind blows from the left or right side of the main body 1, when the wind blows from the right, the wind will first be guided by the guide groove 311 and blow towards the fixed rod 211. When the wind blows directly towards the fixed rod 211, it will be blocked by the rotating plate 321 and the top sliding plate 322, causing the starting plate 212 to slide towards the synchronization plate 313. The sliding of the starting plate 212 will cause the rubber plate 315 between the starting plate 212 and the synchronization plate 313 to deform. When the starting plate 212 and the synchronization plate 313 are close together, the top of the deformed rubber plate 315 will be bent by the blocking strip 314, thus forming a new wind deflector. Since both the starting plate 212 and the synchronization plate 313 can rotate, when passing through the newly formed wind deflector, it will drive the starting plate 212 and the synchronization plate 313 to rotate around the fixed rod 211, passing through the rubber plate 315 to form... The wind from the baffle plate will be guided down through the guide groove 311 on the right side of the synchronization plate 313 and blown out into the exhaust duct 312 and re-mixed into the airflow. When the wind blows from the left, the wind will first be guided by the guide groove 311 on the right side of the synchronization plate 313 and blow towards the synchronization plate 313, thereby pushing the synchronization plate 313 closer to the starting plate 212. This causes the rubber plate 315 to form a baffle plate on the side close to the starting plate 212, thereby causing the starting plate 212 and the synchronization plate 313 to rotate. This improves the smoothness of the movement of the moving plate 221 under different wind directions. Due to the setting of the guide groove 311, the turbulence generated in the internal space of the main body 1 when the wind blows from the left or right is reduced, which may prevent the starting plate 212 and the synchronization plate 313 from rotating. This further improves the smoothness of the starting plate 212's rotation in the face of different wind directions.

[0093] When the wind blows towards the fixed rod 211 under the guidance of the guide groove 311, the rotating plate 321 will rotate on the side wall of the starting plate 212 under the thrust of the wind. Since the top and bottom lengths of the rotating plate 321 are different, with the top length being longer than the bottom length, the rotating plate 321 rotates mostly in the direction of the side rubber plate 315 at the top. When the rotating plate 321 rotates, the sliding plate 322 will rotate synchronously with it. The contact plate 324 at the bottom of the sliding plate 322 will first contact the rubber plate 315, thereby guiding the direction of deformation of the rubber plate 315. The four rubber plates 315 maintain the same direction when deforming. When the starting plate 212 and the synchronization plate 313 gradually approach each other, the sliding plate 322 will be blocked by the synchronization plate 313 and move towards the rotating plate 321. When the sliding plate 322 moves towards the rotating plate 321, the elastic plate 323 will deform under the compression of the sliding plate 322. When 323 deforms, the protruding elastic plate 323 contacts the bottom of the deformed rubber plate 315, causing the bottom of the rubber plate 315 to shift towards the synchronous plate 313, thereby increasing the tilt angle of the rubber plate 315 during deformation. When wind blows towards the synchronous plate 313 from the guide groove 311 of the rotating plate 321 on the right side of the synchronous plate 313, the top of the rotating plate 321 will rotate towards the moving plate 221. At this time, the sliding plate 322 at the bottom of the rotating plate 321 will move towards the rubber plate 315. The movement of the rubber plate 315 in the direction of the bottom sliding plate 322 and the touch plate 324 will also guide the deformation direction of the rubber plate 315, so that the deformation direction of the rubber plate 315 remains consistent when the synchronous plate 313 moves towards the starting plate 212. Due to the setting of the rotating plate 321, the shaking caused by the starting plate 212 being pushed by the wind will reduce the inconsistent deformation direction of the rubber plate 315, thereby further improving the consistency of the deformation direction of the rubber plate 315 when the starting plate 212 or the synchronous plate 313 is pushed.

[0094] As the movable plate 221 moves downward, it moves away from the exhaust plate 222. As the movable plate 221 moves away from the exhaust plate 222, the deformable plate 225 gradually opens up due to the movement of the movable plate 221. Figure 8In the configuration of the R-shaped structure, when strong winds accompany rain, the downward movement of the exhaust plate 222 and the moving plate 221 will cause external air and rainwater to enter the interior of the cylinder 216 through the sponge sleeve outside the noise meter 121. At this time, the moving plate 221 moves away, causing the rubber sheet to open under the weight of the rainwater, allowing the rainwater to be discharged downward through the cylinder 216. When the moving plate 221 moves upward, it will push the deformation plate 225 upward. When the deformation plate 225 moves upward, it will cause the guide plate 223 at the top of the exhaust plate 222 to generate friction with the inner wall of the cylinder 216, thus creating a certain resistance to the deformation plate 225 at the bottom. Under the obstruction of the moving plate 221 and the top exhaust plate 222, the deformation plate 225 will deform to a certain extent. The side of the deformation plate 225 closest to the moving plate 221 will move closer to the inner wall of the cylinder 216 under the push of the moving plate 221, and eventually move to the moving plate 221. Between the side wall of 21 and the inner wall of the cylinder 216, the side wall of the deformation plate 225 will form friction with the inner wall of the cylinder 216, slowing down the upward movement of the air pushed by the moving plate 221 and the exhaust plate 222. At the same time, the mutual approach between the starting plate 212 and the synchronization plate 313 causes the rubber strip 325 to deform to a certain extent. After the rubber strip 325 is deformed, it will form friction with the outer surface of the fixed rod 211. When the starting plate 212 and the synchronization plate 313 rotate, the friction formed between the rubber strip 325 and the fixed rod 211 will slow down the rotation speed of the starting plate 212, thereby indirectly slowing down the rising and falling speed of the moving plate 221. Due to the setting of the guide plate 223, the deformation plate 225 and the rubber strip 325, the situation where the moving plate 221 moves up and down too fast and causes sound to be generated inside the cylinder 216 is reduced, thereby further improving the accuracy of the noise meter 121 in detecting road noise.
