Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring and relates to the detection of noise and dust, specifically a split-type noise and dust monitoring sensor. Background Technology

[0002] Noise and dust monitoring sensors are mainly used for real-time monitoring of noise levels in the environment (decibels) and dust concentrations (such as PM2.5 and PM10). Their core principles are as follows: 1. Noise monitoring principle: Acoustic sensor signal acquisition: Sound wave vibrations in the environment are collected through a built-in microphone, converting the sound pressure signal into an electrical signal. Signal processing and analysis: After amplification and filtering, the electrical signal is converted into a digital signal by an analog-to-digital converter (ADC). The noise level (decibels) is then calculated using algorithms, and parameters such as the noise frequency distribution are analyzed. 2. Dust monitoring principle: Laser scattering method (mainstream technology): A laser beam is emitted internally by the sensor. When airborne particles (such as dust) pass through the detection area, the laser beam is scattered. A photodetector captures the intensity and angle of the scattered light, and the concentration of the particles (unit: μg / m³) is calculated using Mie scattering theory. 3 It can monitor particulate matter of different sizes, such as PM2.5 and PM10; β-ray absorption method (for high-precision applications): It utilizes the principle that when β-rays pass through dusty air, the adsorption of particulate matter causes the intensity of the ray to decrease, and the mass concentration of particulate matter is calculated by measuring the amount of decrease; This method has high precision, but the equipment is larger and more expensive;

[0003] Noise and dust monitoring sensors typically need to balance monitoring accuracy and environmental adaptability. Common installation methods involve using bolts and mounting frames to install sensors on poles or building exteriors at monitoring points such as construction sites, roadsides, and factory perimeters, at a height of 3-5 meters (to avoid ground obstruction and human interference). In actual operation, holes need to be drilled in advance on the poles, walls, or other fixed surfaces to pre-embed bolts, or expansion bolts can be used for direct fixing. This requires a high level of technical skill from the installers and specialized tools such as electric drills and wrenches. If the installation location is a concrete wall or a metal pole, the drilling process is time-consuming and laborious, increasing the safety risks associated with working at heights. Utility Model Content

[0004] The purpose of this invention is to provide a split-type noise and dust monitoring sensor to address the deficiencies mentioned in the background section.

[0005] To achieve the above objectives, a split-type noise and dust monitoring sensor is provided, including a mounting frame. A dust sensor A is mounted on one side of the mounting frame, and a dust sensor B is mounted on the other side of the mounting frame. A noise sensor is located in the middle of the mounting frame. A quick-release bracket structure is mounted at the bottom of the mounting frame. A column is located at the bottom of the quick-release bracket structure. A fixing plate is located on the quick-release bracket structure. A quick-release column is mounted at the bottom of the fixing plate. A quick-release buckle is located at the bottom of the quick-release column. A quick-release rail is provided on the outer side of the column surface, and a stabilizing groove is provided in the middle of the column.

[0006] Preferably, the dust sensor A and the dust sensor B are symmetrical about the noise sensor, and the bottom of the noise sensor is provided with a connecting frame, the end of which is located below the middle of the fixed frame.

[0007] Preferably, the connecting frame is a "Z"-shaped structure made of metal, with one end of the connecting frame screwed to the bottom of the fixed frame, and the other end of the connecting frame away from the fixed frame screwed to the bottom of the noise sensor.

[0008] Preferably, the bottom of the fixing frame is provided with mounting posts on both sides, and the bottom of the two sets of mounting posts are respectively installed on both sides of the surface of the fixing plate. The fixing plate is circular, and the bottom of the fixing plate is fixedly connected to the quick-release post and quick-release buckle.

[0009] Preferably, the quick-install bracket structure includes a quick-install column, a fixing plate, a pressure relief hole, a quick-install buckle, a stabilizing cylinder, a stabilizing groove, an inner insert column, and a quick-install rail. Multiple sets of pressure relief holes are evenly opened on the outer circumference of the quick-install column. The pressure relief holes are elliptical in shape. Five sets of quick-install buckles are evenly installed at the bottom of the quick-install column. Five sets of quick-install rails are evenly opened on the surface of the column.

[0010] Preferably, the quick-release rail includes a receiving groove and a locking groove, which are connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: five sets of quick-release buckles are respectively rotated and snapped into the interior of five sets of locking slots from five sets of receiving slots. The cross-sections of the locking slots and quick-release buckles are set as right-angled trapezoids, and the cross-sections of the receiving slots are set as rectangles. The snap-fit ​​fixing method replaces the traditional screw fixing method, reducing the time for operators to climb and work, improving the safety and efficiency during installation, and eliminating the need to carry various installation tools, thus reducing the weight of the equipment itself when climbing and installing. It is more convenient and faster in actual operation. The snap-fit ​​fixing does not require tedious operations such as tightening screws one by one and aligning screw holes. Fixing can be completed by plugging and rotating, which greatly shortens the time for high-altitude operations. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 This utility model provides a split-type noise and dust monitoring sensor, including a fixed frame 1. A dust sensor A2 is installed on one side of the surface of the fixed frame 1, and a dust sensor B21 is installed on the other side of the surface of the fixed frame 1. A noise sensor 4 is provided in the middle of the fixed frame 1. A quick-release bracket structure 6 is installed at the bottom of the fixed frame 1. A column 5 is provided at the bottom of the quick-release bracket structure 6. A fixing plate 61 is provided on the quick-release bracket structure 6. A quick-release column 60 is installed at the bottom of the fixing plate 61. A quick-release buckle 63 is provided at the bottom of the quick-release column 60. A quick-release rail 66 is provided on the outer side of the surface of the column 5. A stabilizing groove 65 is provided in the middle of the column 5.

[0023] Working principle: In actual use, when using a ladder for installation, the operator, upon reaching the installation position, holds the fixing frame 1 and inserts the stabilizing cylinder 64 at the bottom of the fixing frame 1 into the stabilizing cylinder 64. Simultaneously, the five sets of quick-release buckles 63 are inserted into the five sets of receiving slots 661. The fixing frame 1 is then rotated, causing the five sets of quick-release buckles 63 to rotate out of the five sets of receiving slots 661 and engage with the five sets of locking slots 662. The locking slots 662 and quick-release buckles 63 have right-angled trapezoidal cross-sections. The 661 has a rectangular cross-section and uses a snap-fit ​​fixing method instead of the traditional screw fixing method. This reduces the time operators spend climbing to heights, improves the safety and efficiency of installation, and eliminates the need to carry various installation tools, reducing the weight of the equipment itself when climbing to install it. This makes actual operation more convenient and faster. The snap-fit ​​fixing eliminates the tedious operations of tightening screws one by one and aligning screw holes. Fixing is completed by plugging and rotating, which greatly shortens the time spent working at heights. It is especially suitable for scenarios that require rapid positioning and avoids the safety risks caused by prolonged stay at heights.

[0024] No tools are required; the insertion and rotation are performed manually, reducing reliance on operator skill levels and making it particularly suitable for temporary work or multi-person collaboration scenarios. Traditional screw connections require one hand to hold the tool and the other to stabilize the component, which can easily lead to imbalance due to a shift in the center of gravity when working at heights. The snap-fit ​​connection allows for simultaneous operation with both hands, maintaining body stability throughout and reducing the probability of falls. The right-angled trapezoidal cross-section design of the locking groove 662 and quick-release buckle 63 provides clear feedback on rotation and locking position, avoiding misjudgments due to "incomplete fixation." Repeated disassembly and assembly of screw connections can easily lead to thread wear, affecting the fixing strength. The snap-fit ​​structure eliminates thread wear issues and can be repeatedly disassembled and assembled multiple times. It remains stable even after multiple adjustments, making it suitable for scenarios requiring frequent adjustments. Disassembly only requires rotating the fixing bracket 1 in the reverse direction to release the snap-fit, eliminating the need to remove each screw individually, making it especially suitable for emergency repairs. The combination design of the rectangular receiving groove and the trapezoidal locking groove 662 allows for direct visual assessment of the fixing status, reducing the risk of omissions during concealed installations. No need to purchase screws, nuts, or other consumables, reducing the cost per installation. Long-term use avoids additional expenses due to lost or damaged tools. In harsh environments such as humidity and dust, screw connections are prone to rust or thread blockage by foreign objects, while the snap-fit ​​structure, with its closed plug design, reduces impurity intrusion and extends service life.

[0025] When the fixing frame 1 is fixed to the column 5 by the quick-release bracket structure 6, the stabilizing cylinder 64 is inserted into the inside of the stabilizing groove 65, and the inner insert 651 is inserted into the inside of the inner slot opened inside the stabilizing cylinder 64, which can increase the friction between the quick-release column 60 and the column 5, so that the quick-release column 60 and the column 5 are stable after being snapped together.

[0026] In a preferred embodiment, dust sensor A2 and dust sensor B21 are symmetrical about noise sensor 4. A connecting frame 3 is provided at the bottom of noise sensor 4, and the end of the connecting frame 3 is located below the middle of the fixed frame 1.

[0027] As a preferred embodiment, the connecting frame 3 is a "Z"-shaped structure made of metal. One end of the connecting frame 3 is screwed to the bottom of the fixing frame 1, and the end of the connecting frame 3 away from the fixing frame 1 is screwed to the bottom of the noise sensor 4.

[0028] As a preferred embodiment, mounting posts are provided on both sides of the bottom of the fixing frame 1. The bottoms of the two sets of mounting posts are respectively installed on both sides of the surface of the fixing plate 61. The fixing plate 61 is circular, and the bottom of the fixing plate 61 is fixedly connected to the quick-release buckle 63 through the quick-release post 60.

[0029] As a preferred embodiment, the quick-install bracket structure 6 includes a quick-install column 60, a fixing plate 61, a pressure relief hole 62, a quick-install buckle 63, a stabilizing cylinder 64, a stabilizing groove 65, an inner insert column 651, and a quick-install rail 66. Multiple sets of pressure relief holes 62 are evenly provided on the outer circumference of the quick-install column 60. The pressure relief holes 62 are elliptical in shape. Five sets of quick-install buckles 63 are evenly installed at the bottom of the quick-install column 60. Five sets of quick-install rails 66 are evenly provided on the surface of the column 5.

[0030] Multiple sets of pressure relief holes 62 are evenly opened on the outer circumference of the quick-connect column 60. When the wind impacts the quick-connect column 60, it can pass through the pressure relief holes 62, which can reduce the impact force of the airflow on the quick-connect column 60, reduce the sway amplitude of the quick-connect column 60 when it is impacted by the wind, and improve the stability of the device during use.

[0031] In a preferred embodiment, the quick-release rail 66 includes a receiving groove 661 and a locking groove 662, which are connected. The locking groove 662 and the quick-release buckle 63 are matched in size. The quick-release buckle 63 is inserted into the inside of the receiving groove 661 and rotated into the inside of the locking groove 662. The cross-sections of the locking groove 662 and the quick-release buckle 63 are right-angled trapezoids, and the cross-section of the receiving groove 661 is rectangular.

[0032] In a preferred embodiment, an inner insertion post 651 is fixedly provided inside the stabilizing groove 65. The stabilizing groove 65 is adapted to the size of the stabilizing cylinder 64. The stabilizing cylinder 64 is inserted into the inside of the stabilizing groove 65. The depth of the stabilizing groove 65 is equal to the height of the stabilizing cylinder 64. An inner insertion hole adapted to the size of the inner insertion post 651 is opened inside the stabilizing cylinder 64. The inner insertion post 651 is inserted into the inside of the inner insertion hole.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
