Description

Technical Field

[0001] This invention relates to the field of noise monitoring device technology, specifically to an urban road environmental noise monitoring device based on a monitoring pole. Background Technology

[0002] An environmental noise monitoring device is a specialized piece of equipment used for real-time collection and analysis of environmental noise data. It typically includes noise sensors, a data acquisition module, communication and protection structures, and can continuously monitor indicators such as equivalent sound level and maximum sound level, providing accurate data for noise control. Noise monitoring is carried out on urban roads for three reasons: first, dense traffic flow and the continuous noise generated by horns, engines, and tire friction can affect the lives and health of nearby residents; second, it can help to understand the distribution patterns of noise, providing a basis for planning road noise reduction, traffic restrictions, speed limits, and sound insulation for green spaces; and third, it can provide early warnings of exceeding standards, assisting environmental protection and traffic management departments in law enforcement and control.

[0003] However, existing noise monitoring devices have a fixed clamping range in traditional clamps, which is difficult to adjust flexibly according to the installation scenario. This can easily lead to problems such as the device shaking due to loose clamping or the pole being damaged due to excessive clamping, making it difficult to meet the needs of rapid deployment in a wide range of urban roads and multiple scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide an urban road environmental noise monitoring device based on a monitoring pole. By setting a fixing part, it solves the problems of existing noise monitoring devices, where the clamping range of traditional clamps is fixed and it is difficult to adjust flexibly according to the installation scenario. The devices are prone to problems such as loose clamping causing the device to shake and tight clamping damaging the pole, making it difficult to meet the needs of rapid deployment in a wide range of urban roads and multiple scenarios.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an urban road environmental noise monitoring device based on a monitoring pole, comprising a monitoring pole and a noise detection device mounted on the monitoring pole, and further comprising: a fixing part mounted on the monitoring pole; an mounting part mounted on the noise detection device; and an adjusting part mounted on the mounting part. The fixing part includes a contact assembly mounted on the monitoring pole; and two pressing assemblies, both mounted on the monitoring pole. The contact assembly includes two fixing rings sleeved on the outer wall of the monitoring pole, with several bolts passing through the two fixing rings. Several elastic plates are fixedly connected to the opposite sides of the two fixing rings, and several downward pressing rings are provided on the outer walls of the elastic plates. The two fixing rings are fixed together by several bolts, and the noise detection device is fixedly connected to the fixing ring located on the right side.

[0007] Furthermore, the mounting portion includes a locking component mounted on the noise detection device; and a protective component mounted on the locking component.

[0008] Furthermore, the adjusting part includes a rotating assembly disposed on the mounting part; and a locking assembly disposed on the rotating assembly.

[0009] Furthermore, the extrusion assembly includes two fixing blocks disposed on the outer wall of the fixing ring, with bidirectional threaded rods passing through the two fixing blocks and threadedly connected to the two fixing blocks. A handle is fixedly connected to the bottom of the bidirectional threaded rod. Two limiting blocks are disposed on the outer wall of the fixing ring, with sliding rods passing through the two limiting blocks and slidably connected to the two limiting blocks. The sliding rods are fixedly connected to the corresponding fixing rings, and the two fixing blocks are respectively fixedly connected to the corresponding lower pressure rings.

[0010] Furthermore, the locking assembly includes a placement slot formed on the noise detection device, a limiting plate fixedly connected to the inner wall of the placement slot, a connecting rod passing through the limiting plate, a limiting groove formed on the connecting rod, a limiting element provided at the top of the connecting rod, the limiting groove being adapted to the limiting plate, the limiting element including a connecting plate fixedly connected to the top of the connecting rod, the connecting plate being in contact with the fixed plate, and the connecting plate being hexagonal.

[0011] Furthermore, the protective component includes a fixed plate disposed on the top of the noise detection device, a connecting rod 1 passing through the fixed plate, a connecting rod 2 fixedly connected to the top of the fixed plate, a protective cover disposed at the end of the connecting rod 2, and a sound-silencing component disposed on the protective cover. The protective cover is used to protect the noise detection device, and the sound-silencing component includes a buffer pad disposed on the outer wall of the protective cover. The buffer pad is made of sponge material, and rainwater hitting the buffer pad will not produce sound.

[0012] Furthermore, the rotating assembly includes a connecting ball fixedly connected to the two ends of the connecting rod, a rotating ball rotatably connected to the inner wall of the connecting ball, and a protective cover fixedly connected to the rotating ball.

[0013] Furthermore, the locking assembly includes a plurality of pressing plates disposed on the connecting ball, all of which are in contact with the rotating ball. A rotating ring is fixedly connected to the top of the plurality of pressing plates, and a second pressing ring is rotatably connected to the top of the rotating ring. The second pressing ring is threadedly connected to the second connecting rod. Five pressing plates are disposed and arranged in a circumferential array.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention, through the setting of a fixing part, first aligns two semi-circular fixing rings to wrap around the monitoring pole and initially locks them with bolts; then, rotating the handle drives the bidirectional threaded rod to rotate synchronously, causing the two fixing blocks to move towards each other along the pole body; the fixing blocks push the corresponding lower pressure ring to move synchronously, thereby squeezing the elastic plates on both sides to contract inward until the elastic plates are tightly attached to the surface of the monitoring pole, completing the secure installation of the device; during operation, the handle is rotated alternately on one side to ensure that the elastic plates on both sides are subjected to uniform force, avoiding uneven load caused by excessive tightness on one side, and can be adapted to monitoring poles of various diameters and materials, without the need to customize clamps for specific pole types, reducing production and deployment costs.

[0016] 2. This invention, through the installation section, first places the fixing plate on top of the noise detection device, aligning the fixing plate with the pre-drilled holes of the limiting plate. Then, the connecting rod is inserted into the limiting plate. During insertion, the connecting rod expands the limiting plate, passes through the rear limiting plate, and springs back into the limiting groove to achieve self-locking. The fixing plate is then securely fixed by the connecting plate. A connecting rod and a protective cover are installed above the fixing plate. A sponge cushioning pad is laid on the outside of the protective cover. Rainwater falls directly onto the cushioning pad, utilizing the flexible cushioning properties of the sponge to eliminate raindrop impact noise. At the same time, the protective cover shields and protects the detection head. The protective cover effectively blocks rainwater and dust, preventing rainwater from seeping into or clogging the noise detection head, preventing the detection head from being damaged by moisture, and improving the working stability and service life of the device in rainy weather.

[0017] 3. This invention features an adjustment mechanism. Rotating the second lower pressure ring causes the rotating ring and the extrusion plate to move upwards. Because the rotating ring and the second lower pressure ring are in a rotating fit, the extrusion plate only moves axially up and down without rotating with it. After the extrusion plate moves upwards, it separates from the rotating ball and releases the lock. At this point, the protective cover can be rotated, causing the rotating ball to deflect freely within the connecting ball to adapt to the required angle. After adjustment, the second lower pressure ring is rotated in the opposite direction, causing the extrusion plate to move downwards and press against the rotating ball. The rotating ball is fixed within the connecting ball by friction locking, thus locking the angle of the protective cover. The tilt angle of the protective cover can be freely adjusted according to different road sections, wind direction changes, and rainfall angles, making the protection direction highly matched with environmental conditions and the protection effect more targeted.

[0018] 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

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10 As shown, the present invention is an urban road environmental noise monitoring device based on a monitoring pole, including a monitoring pole 111 and a noise detection device 112 installed on the monitoring pole 111, and further including: a fixing part 2, which is installed on the monitoring pole 111; a mounting part 3, which is installed on the noise detection device 112; and an adjustment part 4, which is installed on the mounting part 3.

[0034] The fixing part 2 includes a contact assembly 21, which is mounted on the monitoring rod 111; and a pressing assembly 22, of which two are provided, both of which are mounted on the monitoring rod 111. The contact assembly 21 includes two fixing rings 211 sleeved on the outer wall of the monitoring rod 111, with several bolts 212 passing through the two fixing rings 211.

The protective assembly 32 includes a... A connecting rod 313 passes through a fixed plate 321 on the top of the noise detection device 112. A connecting rod 322 is fixedly connected to the top of the fixed plate 321. A protective cover 323 is provided at the end of the connecting rod 322. A sound-absorbing component is provided on the protective cover 323. The protective cover 323 is used to protect the noise detection device 112. The sound-absorbing component includes a buffer pad 324 provided on the outer wall of the protective cover 323. The buffer pad 324 is made of sponge material. Rainwater hitting the buffer pad 324 will not make a sound. By setting the mounting part 3, the protective cover 323 can effectively block rainwater and dust, prevent rainwater from seeping into or clogging the noise detection head, prevent the detection head from being damaged by moisture, and improve the working stability and service life of the device in rainy weather.

[0036] The adjustment unit 4 includes a rotating assembly 41, which is mounted on the mounting unit 3; and a locking assembly 42, which is mounted on the rotating assembly 41. The rotating assembly 41 includes a connecting ball 411 fixedly connected to the end of the connecting rod 322. A rotating ball 412 is rotatably connected to the inner wall of the connecting ball 411. The protective cover 323 is fixedly connected to the rotating ball 412. The locking assembly 42 includes several pressing plates 421 mounted on the connecting ball 411. The pressing plates 421 are all in contact with the rotating ball 412. A rotating ring 422 is fixedly connected to the top of the pressing plates 421. A lower pressure ring 423 is rotatably connected to the top of the rotating ring 422. The lower pressure ring 423 is threadedly connected to the connecting rod 322. There are five pressing plates 421 arranged in a circumferential array. By setting the adjustment unit 4, the tilt angle of the protective cover 323 can be freely adjusted according to different road sections, wind direction changes, and rainfall angles, so that the protection direction is highly matched with environmental conditions and the protection effect is more targeted.

[0037] It should be noted that the noise detection device 112 in this application can be controlled by using a program set in the control panel, and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0038] In use, first fix the noise detection device 112 to the monitoring pole 111. When fixing, first put the two fixing rings 211 together, and then fix them together with bolts 212. After fixing, the two pressure rings 214 will be put together. Then turn the handle 223. When the handle 223 is turned, the bidirectional threaded rod 222 will also rotate. When the bidirectional threaded rod 222 rotates, it will bring the two fixing blocks 221 closer to each other. As they get closer, the corresponding pressure rings 214 will also move. When the pressure rings 214 move, they will squeeze the corresponding elastic plate 213 inward. As the elastic plate 213 is squeezed, it will contact the monitoring pole 111. When turning the handle 223, it is necessary to turn it one side at a time to prevent one side from being too tight and the other side from being too loose. After the elastic plate 213 contacts the monitoring pole 111, the noise detection device 112 can be fixed to the monitoring pole 111.

[0039] After fixing, connect rod 322 and buffer pad 324 are fixed to noise detection device 112. During fixing, first place fixing plate 321 on top of noise detection device 112 and align the reserved hole of fixing plate 321 with the reserved hole of limiting plate 312. After alignment, insert connect rod 313 into limiting plate 312. As it is inserted, connect rod 313 will contact limiting plate 312. Continuous downward pressure will open limiting plate 312, and then connect rod 313 will pass through limiting plate 312. At this time, limiting plate 312 will be stuck in limiting groove 314. After the connecting rod 313 is locked, the fixing plate 321 can be fixed to the noise detection device 112 by the connecting plate 315. After the fixing is completed, the detection head of the noise detection device 112 can be protected by the protective cover 323 to prevent rainwater from clogging and damaging the detection head. When it rains, the rainwater will fall directly on the buffer pad 324. Because the buffer pad 324 is made of sponge material, there is no sound when the rainwater falls on the buffer pad 324. Therefore, it will not affect the noise detection device 112's noise detection, thereby achieving the effect of protecting the noise detection device 112.

[0040] The angle of the protective cover 323 can be adjusted to better protect the noise detection device 112 under different times and weather conditions. During adjustment, the lower pressure ring 423 is rotated. At this time, the lower pressure ring 423 will move the rotating ring 422 and the extrusion plate 421 upward. Since the rotating ring 422 is rotatably connected to the lower pressure ring 423, the rotating ring 422 will only move up and down and will not rotate. As the extrusion plate 421 moves upward, it will disengage from the rotating ball 412. After disengagement, the protective cover 323 can be rotated. At this time, the rotating ball 412 will rotate within the connecting ball 411 to match the movement of the protective cover 323. After adjustment, the lower pressure ring 423 is rotated in the opposite direction. At this time, the lower pressure ring 423 will move downward. As it moves, the extrusion plate 421 will contact the rotating ball 412 again and restrict the rotating ball 412 within the connecting ball 411 through friction. In this way, the angle of the protective cover 323 can be adjusted to adapt to different weather, seasons and road sections.
