Description

Technical Field

[0001] This utility model relates to the field of environmental noise monitoring technology, specifically to an environmental noise monitoring device. Background Technology

[0002] In today's society, with the acceleration of urbanization, the continuous expansion of industrial production, and the increasing density of transportation networks, environmental noise pollution has become increasingly prominent, seriously impacting people's quality of life, physical and mental health, and the ecological environment. Therefore, accurate and efficient monitoring of environmental noise has become a crucial aspect of environmental management and protection. However, existing environmental noise monitoring equipment has revealed many problems in practical applications, urgently requiring innovation and improvement.

[0003] According to announcement number CN 221629223 U, a device for environmental noise monitoring includes a mounting column with a noise detector fixedly mounted on the top of the mounting column, a monitoring display mounted on the front of the mounting column, an adjustment component and a maintenance component provided on the back of the monitoring display, a vertical column movably inserted into the bottom of the mounting column, a base plate fixedly provided at the bottom of the vertical column, and telescopic support frames hinged at the four corners of the top of the base plate.

[0004] This device, consisting of a bidirectional threaded rod, movable blocks, brackets, connecting blocks, and sleeves, allows for easy maintenance of environmental noise monitoring equipment by rotating the bidirectional threaded rod. Rotating the rod causes the movable blocks, screwed to both ends, to move relative to each other, pushing the connecting blocks away from the mounting post and separating the display from the sleeve. This allows for inspection of the display's connection cable without removing the display from the mounting post. However, the fixed height of the noise monitor makes it difficult to adapt to complex and changing monitoring environments. Whether monitoring high-altitude noise near tall buildings or noise in low-ceilinged spaces like basements, the fixed-height monitor cannot accurately capture noise information at the corresponding height, leading to data inaccuracies and failing to accurately reflect the actual noise situation. Utility Model Content

[0005] The purpose of this invention is to provide an environmental noise monitoring device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental noise monitoring device, including a base, with casters fixedly connected to the bottom of the base, a height adjustment mechanism provided on the top of the base, and limit mechanisms provided on the left and right sides of the top of the base;

[0007] The height adjustment mechanism includes a fixed box, which is fixedly connected to the top of the base. A sliding plate is slidably connected to the inner wall of the fixed box. A lifting box is fixedly connected to the top of the sliding plate. Handles are symmetrically fixedly connected to the left and right sides of the lifting box near the bottom. A display screen is fixedly connected to the top of the fixed box near the top. A noise monitor is fixedly connected to the top front of the lifting box. A slider is fixedly connected to the bottom front of the lifting box. A fixed plate is fixedly connected to the front of the slider. First guide rods are symmetrically arranged on the left and right sides of the front of the fixed plate. A pull plate is fixedly connected to the front end of the first guide rod. A sliding ring is fixedly connected to the rear end of the first guide rod. A spring is sleeved between the fixed plate and the sliding ring on the surface of the first guide rod. Insert blocks are symmetrically fixedly connected to the back of the sliding ring. Slots corresponding to the insert blocks are equidistantly opened on the front of the fixed box.

[0008] Preferably, the top of the fixed box has a groove that matches the lifting box, and the surface of the lifting box is connected to the groove through and slides up and down. The left and right sides of the fixed box have grooves, and the handle moves up and down in the groove.

[0009] Preferably, the front of the fixing box has a groove that matches the slider, and the surface of the slider is connected to the groove by sliding up and down. The left and right sides of the front of the fixing plate have holes that match the first guide rod, and the surface of the first guide rod is connected to the hole by sliding back and forth.

[0010] Preferably, the inner wall of the sliding ring is slidably connected to the surface of the slider, the front end of the spring is fixedly connected to the back of the fixing plate, the rear end of the spring is fixedly connected to the front of the sliding ring, and the display screen and the noise monitor are connected by wires.

[0011] Preferably, the limiting mechanism includes a fixed frame, which is symmetrically fixedly connected to the top of the base. A lead screw is symmetrically rotatably connected to the top of the base. A crank is fixedly connected to the top of the lead screw. A movable plate is threadedly connected to the surface of the lead screw. Limiting rods are symmetrically fixedly connected to the top of the fixed frame. A second guide rod is symmetrically fixedly connected to the bottom of the movable plate. A rubber block is fixedly connected to the bottom of the second guide rod.

[0012] Preferably, the top of the fixed frame has a hole, and the surface of the lead screw passes through and is rotatably connected to the hole. The bottom end of the limiting rod is fixedly connected to the top of the base. The front and rear sides of the top of the movable plate have holes that match the limiting rod. The movable plate is slidably connected to the surface of the limiting rod through the holes. The limiting rod limits the movable plate, so that the movable plate moves up and down with the rotation of the lead screw.

[0013] Preferably, the top left and right sides of the base are provided with holes that match the second guide rod, and the surface of the second guide rod passes through and slides up and down in the holes.

[0014] Preferably, the noise monitor is model XM8165.

[0015] Compared with the prior art, the present invention provides an environmental noise monitoring device, which has the following beneficial effects:

[0016] 1. This environmental noise monitoring device uses a sliding plate that moves up and down the inner wall of the fixed box, causing the lifting box to rise and fall synchronously, allowing for flexible adjustment of the noise monitor's height. When monitoring noise at higher locations, such as around high-rise buildings, the lifting box is pushed upwards to raise the noise monitor to a suitable height; for monitoring in low-lying areas, the height can be lowered. Handles are symmetrically positioned on the left and right sides of the lifting box near the bottom, facilitating easy operation for the operator to push the box. Simultaneously, the combination of the slider, fixed plate, first guide rod, pull plate, sliding ring, spring, and insert blocks and slots ensures a stable locking mechanism after height adjustment.

[0017] 2. The limiting mechanism plays a crucial role in this environmental noise monitoring equipment. By turning the crank, the lead screw rotates, and because the lead screw is threadedly connected to the moving plate, the moving plate moves up and down with the rotation of the lead screw. The limiting rods, symmetrically fixed at the top front and back of the fixed frame, limit the movement of the moving plate, ensuring its stable up and down movement. The second guide rod and the rubber block at the bottom of the moving plate, symmetrically fixed at the bottom front and back, allow the rubber block to move downwards to contact the ground after the equipment reaches the monitoring position. This increases the friction between the equipment and the ground, preventing displacement due to external forces such as wind or vibrations from passing vehicles during monitoring, thus improving the stability of the equipment and ensuring the accuracy of the monitoring data.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1-4 This utility model provides a technical solution: an environmental noise monitoring device, including a base 1, a caster wheel 2 fixedly connected to the bottom of the base 1, a height adjustment mechanism 3 provided on the top of the base 1, and limit mechanisms 4 provided on the left and right sides of the top of the base 1.

A lifting box 33 is fixedly connected to the top of the sliding plate 32. Handles 34 are symmetrically fixedly connected to the left and right sides of the lifting box 33 near the bottom. A display screen 35 is fixedly connected to the top of the fixed box 31. A noise monitor 36 is fixedly connected to the top front of the lifting box 33. A slider 37 is fixedly connected to the bottom front of the lifting box 33. A fixed plate 38 is fixedly connected to the front of the slider 37. A first guide rod 39 is symmetrically arranged on the left and right sides of the front of the fixed plate 38. A pull plate 311 is fixedly connected to the front end of the first guide rod 39.

The front end of the spring 313 is fixedly connected to the back of the fixed plate 38, and the rear end of the spring 313 is fixedly connected to the front of the sliding ring 312. The display screen 35 and the noise monitor 36 are connected by wires.

[0034] Example 2

[0035] Please see Figure 5 Furthermore, based on Embodiment 1, a limiting mechanism 4 is obtained.

[0036] The limiting mechanism 4 includes a fixed frame 41, which is symmetrically fixedly connected to the top of the base 1. A lead screw 42 is symmetrically rotatably connected to the top of the base 1. A crank 43 is fixedly connected to the top of the lead screw 42. A movable plate 44 is threadedly connected to the surface of the lead screw 42. A limiting rod 45 is symmetrically fixedly connected to the top of the fixed frame 41. A second guide rod 46 is symmetrically fixedly connected to the bottom of the movable plate 44. A rubber block 47 is fixedly connected to the bottom of the second guide rod 46.

[0037] The top of the fixed frame 41 has a hole, and the surface of the lead screw 42 passes through and is rotatably connected to the hole. The bottom end of the limiting rod 45 is fixedly connected to the top of the base 1. The front and rear sides of the top of the movable plate 44 have holes that match the limiting rod 45, and the movable plate 44 is slidably connected to the surface of the limiting rod 45 through the holes. The limiting rod 45 limits the movable plate 44, so that the movable plate 44 moves up and down with the rotation of the lead screw 42.

[0038] The top left and right sides of the base 1 have holes that match the second guide rod 46, and the surface of the second guide rod 46 is penetrated and slidably connected to the hole.

[0039] In actual operation, when this device is in use, the casters 2 at the bottom of the equipment are fixedly connected to the base 1. When it is necessary to change the monitoring location, the operator can easily push the equipment. The casters 2 can turn flexibly, adapting to different ground conditions, whether on flat city streets or in complex industrial parks, allowing the equipment to quickly move between various monitoring points. The fixed box 31 is fixed to the top of the base 1, and the sliding plate 32 can slide up and down on the inner wall of the fixed box 31. The top of the sliding plate 32 is connected to the lifting box 33. When the operator needs to adjust the height of the noise monitor 36, he can push the lifting box 33 by holding the handles 34 symmetrically arranged on both sides near the bottom of the lifting box 33. Due to the connection between the sliding plate 32 and the lifting box 33, the movement of the lifting box 33 will cause the sliding plate 32 to slide up and down synchronously on the inner wall of the fixed box 31, thereby changing the height of the noise monitor 36. When monitoring noise at high altitudes around high-rise buildings is required, the operator pushes the handle 34 upwards to raise the lifting box 33 to a suitable height. For monitoring in low-ceilinged spaces such as basements, the handle 34 is pulled downwards to lower the lifting box 33. After height adjustment, a locking device consisting of a slider 37, a fixing plate 38, a first guide rod 39, a pull plate 311, a sliding ring 312, a spring 313, and inserts 314 and slots 315 is activated to ensure the lifting box 33 is stably fixed at the set height. The operator pulls the pull plate 311, which moves the first guide rod 39 forward, causing the sliding ring 312 to slide forward on the surface of the slider 37. At this time, the inserts 314, symmetrically fixed to the back of the sliding ring 312, disengage from the slots 315 equidistantly spaced on the front of the fixing box 31. Once the lifting box 33 reaches the target height, the pull plate 311 is released. Under the elastic force of the spring 313, the sliding ring 312 slides backward, and the insert block 314 re-inserts into the slot 315 at the corresponding height, firmly locking the lifting box 33 and ensuring the height stability of the noise monitor 36 during monitoring. When the equipment reaches the monitoring position, the operator turns the crank handle 43, causing the lead screw 42 to move the moving plate 44 downward, thereby causing the second guide rod 46 and the rubber block 47 to descend together. After the rubber block 47 contacts the ground, the crank handle 43 is turned again. The rubber block 47 will exert pressure on the ground, and the ground will also exert a reaction force on the rubber block 47. This reaction force is transmitted to the moving plate 44 through the second guide rod 46 and ultimately acts on the entire equipment, increasing the friction between the equipment and the ground. In this way, even if affected by external factors such as wind or vibrations from passing vehicles, the equipment can remain stable during monitoring and will not shift, effectively ensuring the accuracy of the monitoring data. The noise monitor 36, which is fixedly connected to the top front of the lifting box 33, is the core monitoring component. The noise monitor 36 has a built-in high-precision sound sensor. When noise waves from the external environment reach the monitor, the sensor converts the sound wave signal into an electrical signal.These electrical signals undergo a series of processing steps, including amplification and filtering, within the signal processing circuitry of the noise monitor 36, transforming them into data representing noise intensity and frequency. The display screen 35 is connected to the noise monitor 36 via a wire, and the processed data from the noise monitor 36 is transmitted to the display screen 35 in real time. The display screen 35 presents this data in intuitive numerical and graphical formats, allowing operators to easily monitor the current noise level. For example, operators can directly read the current decibel level of the noise from the display screen 35 to determine if the noise intensity exceeds the standard range. They can also observe the noise trend over a period of time through graphs, providing a basis for subsequent environmental noise analysis and assessment.
