Description

Technical Field

[0001] This utility model relates to the technical field of environmental monitoring equipment, and in particular to an integrated positioning plant boundary noise measurement bracket. Background Technology

[0002] In existing factory boundary noise monitoring technologies, for measurement points with walls, operators must manually hold up a noise extension rod to ensure the microphone meets the specification requirement of being "at least 0.5 meters above the wall and 1 meter away from the wall." This traditional method has three major drawbacks: 1) High dependence on manual labor and poor stability: Relying entirely on manual holding, the rod is prone to shaking or even tilting due to fatigue, introducing measurement errors and posing safety hazards. 2) Inability to guarantee spatial positioning accuracy: Relying entirely on the operator's visual estimation of height and distance cannot meet the strict requirements of the standard for point accuracy, affecting the legal validity of the data. 3) Poor equipment compatibility and low efficiency: The noise meter main unit bracket, extension rod, and ranging tool are independent, cumbersome to assemble and adjust, and cannot ensure that the equipment works in coordination, making the measurement process time-consuming and labor-intensive. Therefore, there is an urgent need for an integrated noise measurement bracket that can achieve rapid and accurate spatial positioning to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated positioning noise measurement bracket for factory boundaries, which can effectively solve the problems of poor stability, inaccurate positioning and low efficiency caused by manual handheld measurement.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated positioning-type factory boundary noise measurement bracket, comprising an acoustic measurement support module and a spatial positioning measurement module; the acoustic measurement support module includes a telescopic triangular bracket, a mounting platform fixed to the top of the telescopic triangular bracket, a telescopic noise extension rod vertically mounted on the mounting platform, and a microphone clamp set at the top of the telescopic noise extension rod; the microphone clamp is used to hold a noise measurement microphone, which is connected to a noise meter host via a signal cable; the spatial positioning measurement module includes a laser ranging positioning unit mounted on the mounting platform; the laser ranging positioning unit includes a support arm and a laser rangefinder, the bottom of the support arm is mounted on the mounting platform, and the top of the support arm is connected to the laser rangefinder via a pan-tilt head to achieve omnidirectional rotation of the laser rangefinder in both horizontal and vertical directions.

[0005] To achieve rapid, stable, and relatively fixed integrated installation of multiple devices, including the noise meter main unit, the retractable noise extension rod, and the laser rangefinder, this application further specifies that the installation platform is equipped with at least three threaded interfaces: a central threaded interface for connecting the retractable noise extension rod, a left-side threaded interface for installing the noise meter main unit, and a right-side threaded interface for connecting the support arm. These standardized threaded interfaces enable plug-and-play functionality and precise positioning of the equipment, significantly improving assembly and adjustment efficiency and ensuring spatial stability of each component.

[0006] To enable the support to adapt to uneven ground and flexibly adjust its overall height to initially meet measurement requirements, this application further specifies that the legs of the telescopic tripod are multi-section telescopic structures, with each leg equipped with a first tightening lock. This enhances the support's adaptability to different terrains and ensures the basic stability of the entire measurement platform through the lockable telescopic legs.

[0007] To ensure precise and convenient adjustment of the final measurement height of the noise measurement microphone to meet the requirement of exceeding the perimeter wall, this application further specifies that the telescopic noise extension rod is a multi-section telescopic structure with a second locking latch on the rod. This achieves stepless, precise adjustment and reliable locking of the measurement height, directly guaranteeing the measurement accuracy in the vertical direction.

[0008] To address the issues of portability when transferring the entire equipment between multiple monitoring points and its stability after on-site positioning, this application further specifies that the bottom of the telescopic tripod is equipped with casters with brakes. This significantly improves the ease of movement of the equipment while ensuring the stability of the tripod during measurement, thus balancing portability and stability.

[0009] To allow for flexible adjustment of the noise measurement microphone's horizontal orientation to align with the noise source without moving the entire support frame, this application further specifies that the microphone clamp can be horizontally rotated 360 degrees and mounted on the top of the retractable noise extension rod. This optimizes the sound wave reception direction, ensures the accuracy of noise data acquisition, and provides greater operational flexibility.

[0010] To automatically convert raw laser ranging data into directly relevant positioning parameters (such as wall height and microphone height) and avoid errors from manual calculations and tedious operations, this application further specifies that the laser rangefinder is a laser rangefinder with data output functionality, which is connected to a control terminal via wired or wireless means. The control terminal receives the data measured by the laser rangefinder and calculates the wall height and the microphone height from the ground. This achieves automatic processing and intelligent feedback of measurement data, upgrading the spatial positioning process from measurement and manual calculation to measurement and automatic interpretation, further improving positioning accuracy and operational efficiency.

[0011] To provide a unified and reliable mounting reference surface for all integrated devices, this application further specifies that the mounting platform is a water platform. This ensures the accuracy of the vertical distance measuring instrument's measurement data and the standardization of the entire system structure, providing a foundation for accurate spatial geometric calculations.

[0012] Compared with the prior art, the beneficial effects of this utility model are: I. Precise positioning and reliable data: Through the integrated laser ranging and positioning unit, the spatial coordinates required by the standard are transformed from vague visual estimation into precise digital readings, ensuring the spatial accuracy of the measurement points and thus guaranteeing the compliance and legal validity of the data.

[0013] Second, high stability: By replacing manual hand-held operation with a floor-standing tripod and lockable telescopic rod, measurement errors caused by shaking are fundamentally eliminated, ensuring the professionalism and accuracy of the measurement.

[0014] III. Integration and High Efficiency: The noise meter main unit, noise extension rod, and laser rangefinder are integrated into one unit through a unified installation platform. The equipment can be quickly assembled and adjusted, the positioning process is clear, significantly improving work efficiency and reducing the labor intensity and skill threshold of operators.

[0015] IV. Strong environmental adaptability: Its fully adjustable design allows it to flexibly cope with various uneven ground and walls of different heights, making it widely applicable. Attached Figure Description

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of this utility model, and not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] See Figure 1 and Figure 2 This utility model discloses an integrated positioning noise measurement bracket for factory boundaries, used for factory boundary noise monitoring, and is particularly suitable for perimeter wall inspection scenarios requiring precise control of measurement height and horizontal distance. The core of this design lies in constructing a fully adjustable mechanical support system and an integrated optical positioning system. The measurement bracket includes an acoustic measurement support module and a spatial positioning measurement module.

[0020] The acoustic measurement support module includes a telescopic tripod 1, a mounting platform 2 fixed to the top of the telescopic tripod 1, a telescopic noise extension rod 3 vertically mounted on the mounting platform 2, and a microphone clamp 4 located at the top of the telescopic noise extension rod 3. The microphone clamp 4 is used to hold a noise measurement microphone, which is connected to a noise meter host 5 via a signal cable. The legs of the telescopic tripod 1 are multi-section telescopic structures, each leg having a first tightening lock 1-1. The bottom of the telescopic tripod 1 is equipped with casters 1-2 with brakes. The mounting platform 2 is a horizontal platform. The mounting platform 2 has at least three threaded interfaces, including a central threaded interface 2-1 for connecting the telescopic noise extension rod 3, a left threaded interface 2-2 for mounting the noise meter host 5, and a right threaded interface 2-3 for connecting the support arm 6. The bottom of the retractable noise extension rod 3 is screwed into the central threaded interface 2-1. The retractable noise extension rod 3 has a multi-section telescopic structure, and a second tightening lock 3-1 is provided on the rod body for locking. In other words, the second tightening lock 3-1 is used to lock the retractable noise extension rod 3 after it has been extended to the desired length. The microphone clamp 4 can be horizontally rotated 360 degrees and mounted on the top of the retractable noise extension rod 3. This application achieves precise adjustment of the support height and measurement height through the retractable tripod 1 and the retractable noise extension rod 3.

[0021] The spatial positioning measurement module includes a laser ranging and positioning unit mounted on the installation platform 2. The laser ranging and positioning unit includes a support arm 6 and a laser rangefinder 7. The bottom of the support arm 6 is mounted on the installation platform 2. Specifically, the bottom of the support arm 6 is screwed into the right-side threaded interface 2-3, and the top of the support arm 6 is connected to the laser rangefinder 7 via a pan-tilt head 8 to achieve omnidirectional rotation of the laser rangefinder 7 in both horizontal and vertical directions. The laser rangefinder 7 is a laser rangefinder with data output function, which is connected to a control terminal via wired or wireless means. The control terminal receives the data measured by the laser rangefinder 7 and calculates the height of the wall and the height of the microphone from the ground. This application integrates the laser rangefinder 7 and a noise measurement device on the same installation platform 2, realizing real-time, non-contact, accurate measurement and feedback of the spatial coordinates of the measurement point.

[0022] Example 1

[0023] See Figure 1 and Figure 2One embodiment of this utility model is an integrated positioning plant boundary noise measurement bracket, the core of which is the construction of a highly integrated acoustic measurement support module and a spatial positioning measurement module.

[0024] The acoustic measurement support module is primarily responsible for providing stable and adjustable physical support for the noise measurement equipment. It includes a telescopic triangular bracket 1 with multi-section telescopic legs. The height of each leg can be adjusted and securely locked via a first tightening lock 1-1 to adapt to uneven terrain and ensure stability. Optional casters 1-2 with brakes are available at the bottom of the bracket for easy movement and fixation. A mounting platform 2 is fixed to the top of the triangular bracket 1, preferably a horizontal platform, to ensure a reference point for measurement. A telescopic noise extension rod 3 is vertically mounted to the central threaded interface 2-1 of the platform 2 via threads at its bottom. This extension rod 3 is also a multi-section telescopic structure, with its height adjusted and locked via a second tightening lock 3-1 on the rod. A microphone clamp 4 is mounted at its top for holding the noise measurement microphone. This microphone clamp 4 can rotate 360 ​​degrees horizontally to adjust the microphone's orientation. The noise measurement microphone is connected to the noise meter main unit 5 via a signal cable, and the noise meter main unit 5 is mounted on the left threaded interface 2-2 of the platform 2.

[0025] The spatial positioning and measurement module is responsible for accurately determining the spatial coordinates of the monitoring points. It includes a laser ranging and positioning unit, the bottom of which is mounted on the threaded interface 2-3 on the right side of the platform 2. The top of the supporting arm 6 is connected to a laser rangefinder 7 via a gimbal 8. This gimbal 8 allows the laser rangefinder 7 to rotate omnidirectionally in both horizontal and vertical directions, enabling it to flexibly aim at the base, top, or microphone position of the wall.

[0026] The laser rangefinder 7 is a model with data output function, which is connected to a control terminal via wired or wireless means.

[0027] The working process of this integrated positioning plant boundary noise measurement bracket is as follows: Step 1, Initial Setup: Unfold the telescopic tripod 1 and adjust its height to a suitable range, then tighten the first locking buckle 1-1. Install each piece of equipment onto platform 2.

[0028] Step 2, Measuring wall parameters: Operate the pan-tilt head 8, use the laser rangefinder 7 to aim at the base (point A) and top (point B) of the wall, obtain the slope distance and angle data, and automatically calculate the wall height H_wall and the current distance S.

[0029] Step 3, Precise Positioning: Step 3-1, Horizontal positioning: Move the entire support and observe the reading of the laser rangefinder 7 to make its horizontal distance from the wall S = 1 meter.

[0030] Step 3-2, Vertical Positioning: First, extend the retractable noise extension rod 3 to the estimated height and lock it using the second tightening latch 3-1. Then, align the laser rangefinder 7 vertically downwards with the center ground point (point C) of the bracket, rotate the gimbal 8 to align the laser rangefinder 7 with the top microphone (point D), automatically calculate the height from the ground to the microphone, and adjust the height of the retractable noise extension rod 3 until it reaches H-wall + 0.5 meters or more, then lock the bracket.

[0031] Example 2

[0032] Compared to Embodiment 1, the difference lies in the following: In this embodiment, a basic laser rangefinder 7 is used. This rangefinder itself does not have complex data output and calculation functions; its measurement results are directly displayed on its own screen. The control terminal is a portable device with calculation functions, such as a smartphone or calculator. The operation process is as follows: The operator uses the gimbal 8 to manipulate the laser rangefinder 7 to aim at the base of the wall (point A), the top (point B), and the microphone position (point D). The operator manually reads the distance data displayed on the laser rangefinder screen and manually inputs it into the calculator application or dedicated app on the smartphone. The smartphone then calculates the wall height H_wall and the final microphone height H_final. Alternatively, the operator can manually calculate using the Pythagorean theorem. This embodiment, while ensuring the core advantages of integrated, stable, and adjustable mechanical structure of the measuring support, significantly reduces the manufacturing cost and usage threshold of the entire system by using a basic laser rangefinder and manual reading and calculation. It provides a highly cost-effective solution for application scenarios with limited budgets or low automation requirements, demonstrating the flexibility and universality of this utility model.

[0033] Example 3

[0034] Compared to Embodiment 1, the difference lies in the following: In this embodiment, a dedicated embedded controller is integrated on the mounting platform 2. This controller serves as a control terminal and is directly connected to the laser rangefinder 7 via a data cable. A touchscreen display is located on the side of the mounting platform 2 for human-machine interaction. The embedded controller has a pre-stored positioning calculation program and preset multiple measurement modes. During operation, the operator selects the corresponding mode via the touchscreen and then operates the gimbal 8 to aim at the target point according to the on-screen prompts. The data measured by the laser rangefinder 7 is automatically transmitted to the embedded controller in real time. The controller immediately completes the calculation and displays the results intuitively on the touchscreen, and can guide the operator through the entire positioning process via a graphical interface. The embedded controller can also connect to a cloud server via a wireless module to achieve real-time uploading of measurement data, remote monitoring, and generation of compliant electronic measurement reports. This embodiment, by highly integrating the control terminal onto the bracket body and developing a dedicated control program, achieves full automation and intelligence from measurement and calculation to guidance and adjustment, greatly simplifying the operation steps, reducing the risk of human error, and improving the efficiency and standardization of data management. It represents the high-end development direction and application prospects of this utility model technology.

Any equivalent substitutions or modifications made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
