Description

Technical Field

[0001] This invention relates to the field of environmental noise monitoring technology, specifically to an intelligent environmental noise monitoring instrument. Background Technology

[0002] Noise pollution refers to the phenomenon of sound exceeding national emission standards or failing to take control measures, interfering with others' normal life, work, and study. It mainly originates from transportation, industry, construction, and social life. Its harms include impacting human health and the ecological environment; therefore, noise monitoring is necessary to quantify the degree of pollution, assess the effectiveness of prevention and control measures, and provide a basis for law enforcement. An intelligent environmental noise monitoring instrument is a smart device integrating sensors, data processing, and communication technologies. It is mainly used for real-time collection, analysis, and transmission of environmental noise data. It typically possesses high-precision measurement, automatic calibration, remote monitoring, and data analysis functions, and can be applied to scenarios such as urban noise management, industrial zone monitoring, and traffic noise assessment, helping relevant departments or enterprises achieve accurate monitoring and intelligent management of noise pollution.

[0003] Rainfall generates additional noise, such as the sound of raindrops hitting the ground (approximately 40 decibels), which directly affects measurement accuracy. When wind speeds exceed 5 meters per second, wind noise can reach 35-50 decibels. In such weather conditions, the monitoring instrument should not be used and must be immediately stored and protected. Existing intelligent environmental noise monitoring instruments lack remote protection capabilities. These instruments are mostly deployed outdoors, and when the weather changes, it is inefficient for users to individually store and protect each instrument. This can easily lead to untimely protection and damage to the instruments.

[0004] Therefore, this application proposes an intelligent environmental noise monitoring instrument to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent environmental noise monitor to solve the problem mentioned in the background art, which is that the efficiency of users storing and protecting the intelligent environmental noise monitor one by one is low and the protection is easily delayed.

[0007] The top plate has a notch on its side, a roller is rotatably connected to the inner wall of the notch, and a through hole is provided at the center of the top of the top plate.

[0008] The top plate has a support block fixedly installed on its top, a track rod fixedly installed on the outer wall of the support block, a slider slidably connected to the outer wall of the track rod, and a combined cover plate fixedly installed on the outer wall of the slider.

[0009] The connecting cable is fixedly connected to the top of the combined cover plate at one end away from the connecting block, and an elastic element is fixedly installed on the top of the support block. The elastic element is fixedly installed on the top of the slider at one end away from the support block.

[0010] The outer wall of the protective cylinder is detachably connected with a splicing ring 1 and a splicing ring 2. The end of the splicing ring 1 is provided with a groove, and the end of the splicing ring 2 is movably inserted into the inner cavity of the groove. The top of the splicing ring 1 is threaded with a connecting bolt, and the end of the connecting bolt movably abuts against the outer wall of the splicing ring 2. A remote control box is fixedly installed on the outer wall of the splicing ring 1.

[0011] The adjustable support mechanism includes a receiving seat, a round rod fixedly installed on the top of the receiving seat, an annular seat fixedly installed on the top of the round rod, a sliding seat slidably connected to the outer wall of the round rod, an extension column fixedly installed on the top of the sliding seat, and the extension column fixedly installed at the bottom of the connecting frame.

[0012] The annular seat has a locking block fixedly installed on its inner wall, a roller rotatably connected to the inner wall of the locking block, a protrusion fixedly installed on the top of the annular seat, a threaded component threadedly connected to the inner wall of the protrusion, a clamping component rotatably connected to the end of the threaded component, a clamping block fixedly installed on the outer wall of the clamping component, and the clamping block slidably connected to the protrusion.

[0013] The base of the receiving seat is fixedly installed with a counterweight base, the outer wall of the counterweight base is fixedly installed with a protruding frame, the inner wall of the protruding frame is rotatably connected with a rotating shaft, the outer wall of the rotating shaft is fixedly installed with a support leg, and the outer wall of the support leg is fixedly installed with a caster wheel.

[0014] The bracket has a limiting block fixedly installed on its outer wall. The top of the limiting block is threaded with an assembly bolt, and the bottom of the assembly bolt extends to the bottom of the limiting block. The outer wall of the support leg has a threaded hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the overall design of the remote protection mechanism, this invention allows users to remotely control the extension or retraction of the electric cylinder via their mobile phones and internal components of the remote control box when the weather changes. When extended, the main body of the noise intelligent monitor moves out of the inner cavity of the protective cylinder; when retracted, the main body of the noise intelligent monitor retracts into the inner cavity of the protective cylinder. At this time, the bottom plate, protective cylinder, and top plate fully enclose and protect the main body of the noise intelligent monitor, avoiding the problem of damage to the main body of the noise intelligent monitor caused by weather. No manual protection of the main body of the noise intelligent monitor is required, reducing the labor intensity of the staff and improving the efficiency of maintenance work. 2. When the main body of the noise intelligent monitoring instrument extends out from inside the protective cylinder for use, since one end of the connecting cable is fixed to the outer wall of the protective cylinder, the other end of the connecting cable will pull the combined cover plate, causing the combined cover plate to slide on the top of the top plate, so that the top of the through hole is open. The noise above can pass through the top plate smoothly and be captured by the microphone, avoiding the problem that the top plate completely blocks the top of the noise intelligent monitoring instrument, which can easily have a significant impact on normal noise monitoring.

[0019] 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.

[0020] Please see Figure 1-10 The present invention provides a technical solution: an intelligent environmental noise monitoring instrument, including a main body 11 of the intelligent noise monitoring instrument, a microphone 12 fixedly installed on the top of the main body 11, and further comprising: Connector 1; Remote protection mechanism 2 is installed on the top of the connecting frame 1. Remote protection mechanism 2 is used to remotely protect the main body 11 of the noise intelligent monitoring instrument. Adjustable support mechanism 3 is located at the bottom of the connecting frame 1. Adjustable support mechanism 3 is used to facilitate the user to adjust the position of the main body 11 of the noise intelligent monitoring instrument. The remote protection mechanism 2 includes a base plate 21, which is fixedly installed on the top of the connecting frame 1. A protective cylinder 22 is fixedly installed on the top of the base plate 21, and an electric cylinder 23 is fixedly installed on the bottom of the base plate 21. The telescopic end of the electric cylinder 23 extends into the inner cavity of the protective cylinder 22 and is fixedly connected to the lifting inner seat 24. The main body 11 of the noise intelligent monitoring instrument is fixedly installed on the top of the lifting inner seat 24. A round hole 25 is opened on the top of the lifting inner seat 24. A column 26 is fixedly installed on the top of the lifting inner seat 24. A top plate 27 is fixedly installed on the top of the column 26. A connecting block 28 is fixedly installed on the outer wall of the protective cylinder 22, and a connecting cable 29 is fixedly connected to the outer wall of the connecting block 28.

[0021] It should be noted that users can remotely control the extension or retraction of the electric cylinder 23 via a mobile app. When extended, it causes the main body 11 of the noise intelligent monitoring device to move out of the inner cavity of the protective cylinder 22. When retracted, it causes the main body 11 of the noise intelligent monitoring device to retract into the inner cavity of the protective cylinder 22. At this time, the base plate 21, the protective cylinder 22, and the top plate 27 fully enclose and protect the main body 11 of the noise intelligent monitoring device, avoiding the problem that the main body 11 of the noise intelligent monitoring device is easily damaged due to weather conditions. There is no need for manual protection of the main body 11 of the noise intelligent monitoring device, reducing the labor intensity of the staff and improving the efficiency of maintenance work.

[0022] In one embodiment, a notch 271 is provided on the side of the top plate 27, and a roller 272 is rotatably connected to the inner wall of the notch 271. A through hole 273 is provided at the center of the top of the top plate 27.

[0023] This design is for reference. Figure 5 When the main body 11 of the noise intelligent monitoring instrument extends out of the inside of the protective cylinder 22 for use, the top of the through hole 273 is in the open state, and the noise above can pass smoothly through the top plate 27 and be captured by the microphone 12. This avoids the problem that the top plate 27 completely blocks the top of the main body 11 of the noise intelligent monitoring instrument, which could easily have a significant impact on normal noise monitoring. The connecting cable 29 is attached to the top of the roller 272. This design can reduce the wear of the connecting cable 29.

[0024] In one embodiment, a support block 274 is fixedly installed on the top of the top plate 27, a track rod 275 is fixedly installed on the outer wall of the support block 274, a slider 276 is slidably connected to the outer wall of the track rod 275, and a combined cover plate 278 is fixedly installed on the outer wall of the slider 276.

[0025] This design is for reference. Figure 4The combined cover plate 278 can slide left and right on the outer wall of the track rod 275 with the help of the slider 276, so that the combined cover plate 278 can be opened or closed at the top of the through hole 273 for easy use.

[0026] In one embodiment, the end of the connecting cable 29 away from the connecting block 28 is fixedly connected to the top of the combined cover plate 278, and an elastic element 277 is fixedly installed on the top of the support block 274. The end of the elastic element 277 away from the support block 274 is fixedly installed on the top of the slider 276.

[0027] This design is for reference. Figure 4 In the initial state, the elastic force of the elastic element 277 can push the slider 276, causing the slider 276 to slide at the end of the track rod 275. The two combined cover plates 278 are spliced ​​on the top of the through hole 273 to block the through hole 273. When the main body 11 of the noise intelligent monitor extends out of the inside of the protective cylinder 22 for use, since one end of the connecting cable 29 is fixed to the outer wall of the protective cylinder 22, the other end of the connecting cable 29 will pull the combined cover plate 278, causing the combined cover plate 278 to slide on the top of the top plate 27, so that the top of the through hole 273 is in the open state. After the main body 11 of the noise intelligent monitor moves down and resets, the reset elastic force of the elastic element 277 will drive the combined cover plate 278 to reset.

[0028] The connecting cable 29 is initially in a relaxed state. When the device moves up, since one end of the connecting cable 29 is fixed, the connecting cable 29 gradually switches to a taut state. The taut connecting cable 29 will apply tension to the elastic element 277 to open it. During the descent of the main body 11, the elastic element 277 will also slowly pull the connecting cable 29 back to its original position, thereby effectively closing the cover.

[0029] In one embodiment, a first splicing ring 222 and a second splicing ring 224 are detachably connected to the outer wall of the protective cylinder 22. The end of the first splicing ring 222 has a groove 223, and the end of the second splicing ring 224 is movably inserted into the inner cavity of the groove 223. The top of the first splicing ring 222 is threadedly connected to a connecting bolt 225, and the end of the connecting bolt 225 movably abuts against the outer wall of the second splicing ring 224. A remote control box 221 is fixedly installed on the outer wall of the first splicing ring 222.

[0030] This design is for reference. Figure 6The remote control box 221 includes a main control module, an electric cylinder drive module, a communication module, and a power supply module. The main control module is an ESP32, which is responsible for receiving commands and controlling the electric cylinder 23. The electric cylinder drive module controls the on / off state through a relay or solid-state switch. The communication module is a 4G module, such as a SIM7600, used to connect to a cloud server or mobile APP. The power supply module provides a stable power supply for the electric cylinder 23 and the main control module. When installing the remote control box 221 on the outer wall of the protective cylinder 22, the splicing ring 224 is inserted into the groove 223, which simultaneously causes the splicing ring 222 and the splicing ring 224 to assemble on the outer wall of the protective cylinder 22. Then, the connecting bolt 225 is tightened.

[0031] In one embodiment, the adjustable support mechanism 3 includes a receiving seat 31, a round rod 32 is fixedly installed on the top of the receiving seat 31, an annular seat 33 is fixedly installed on the top of the round rod 32, a sliding seat 34 is slidably connected to the outer wall of the round rod 32, an extension column 35 is fixedly installed on the top of the sliding seat 34, and the extension column 35 is fixedly installed at the bottom of the connecting frame 1.

[0032] This design is for reference. Figure 7 During the instrument debugging process, the overall working height of the main body 11 of the noise intelligent monitoring instrument can be adjusted by sliding the sliding seat 34 on the outer wall of the round rod 32.

[0033] In one embodiment, a fitting block 331 is fixedly installed on the inner wall of the annular seat 33, a roller 332 is rotatably connected to the inner wall of the fitting block 331, a protrusion 333 is fixedly installed on the top of the annular seat 33, a threaded member 334 is threadedly connected to the inner wall of the protrusion 333, a clamping member 335 is rotatably connected to the end of the threaded member 334, and a clamping block 336 is fixedly installed on the outer wall of the clamping member 335, and the clamping block 336 is slidably connected to the protrusion 333.

[0034] This design is for reference. Figure 8 When the sliding seat 34 slides on the outer wall of the round rod 32, the extension column 35 will slide in contact with the outer wall of the roller 332, thereby increasing stability. If it is necessary to lock the height of the main body 11 of the noise intelligent monitoring instrument, manually rotating the threaded part 334 will push the clamp 335. Under the limit of the clamping block 336, the clamp 335 will move towards the outer wall of the extension column 35 and tightly abut against the outer wall of the extension column 35 to complete the height locking.

[0035] In one embodiment, a counterweight base 36 is fixedly installed at the bottom of the receiving seat 31, a protruding frame 361 is fixedly installed on the outer wall of the counterweight base 36, a rotating shaft 362 is rotatably connected to the inner wall of the protruding frame 361, a support leg 363 is fixedly installed on the outer wall of the rotating shaft 362, and a caster wheel 366 is fixedly installed on the outer wall of the support leg 363.

[0036] This design is for reference. Figure 9 , Figure 10 In the initial state, the support leg 363 is in contact with the ground, which can provide relatively stable support for the structure. If the structure needs to be moved, the support leg 363 can be rotated 90 degrees to make the caster wheel 366 contact the ground, and then the structure can be pushed and moved, improving the convenience of the turnover work.

[0037] In one embodiment, a limiting block 364 is fixedly installed on the outer wall of the protrusion 361. The top of the limiting block 364 is threadedly connected to an assembly bolt 365, and the bottom of the assembly bolt 365 extends to the bottom of the limiting block 364. A threaded hole is provided on the outer wall of the support leg 363.

[0038] This design is for reference. Figure 9 , Figure 10 To lock the caster wheel 366 in contact with the ground, rotate the support leg 363 to fit against the bottom of the limit block 364, and then rotate the mounting bolt 365 to extend the end of the mounting bolt 365 into the threaded hole of the support leg 363, thus completing the locking.

[0039] In one embodiment, a fitting 367 is fixedly installed on the outer wall of the support leg 363, a frame 368 is fixedly installed on the bottom of the counterweight base 36, an insert block 3681 is slidably connected on the inner wall of the frame 368, a spring 3682 is fixedly installed on the outer wall of the insert block 3681, and one end of the spring 3682 away from the insert block 3681 is fixedly installed on the inner wall of the frame 368.

[0040] This design is for reference. Figure 9 , Figure 10 If it is necessary to lock the support leg 363 in contact with the ground, push the insert block 3681 towards the inside of the frame 368 beforehand, so that the insert block 3681 compresses the spring 3682 and slides. Then rotate the support leg 363 as a whole, so that the assembly 367 moves to the frame 368. Then release the insert block 3681. Under the action of the spring 3682, the insert block 3681 will be driven to insert into the inside of the assembly 367, that is, lock the support leg 363 in the supported state.

[0041] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification.
