Technical Field
[0001] This utility model relates to the field of duct operation monitoring technology, specifically a duct operation status monitoring device. Background Technology
[0002] Air ducts are core components in HVAC systems used for air transport and distribution, and are widely used in buildings, industrial plants, public places, and other scenarios. Their operating status directly affects the system's energy efficiency, indoor air quality, and overall safety. In actual operation, parameters such as temperature, humidity, air composition, and airflow speed inside the air ducts will fluctuate with changes in the environment. If these parameters exceed reasonable ranges, it may lead to a surge in air conditioning system energy consumption, a decrease in indoor comfort, and even problems such as condensation in the ducts and accumulation of pollutants. Therefore, real-time and accurate monitoring of the operating status of air ducts is a necessary means to ensure the stable and efficient operation of HVAC systems and reduce maintenance costs.
[0003] Traditional duct status monitoring methods rely heavily on manual inspections or single-point sensor measurements, which have significant limitations. Manual inspections are not only time-consuming and labor-intensive, but also difficult to achieve continuous monitoring and are prone to missing momentary parameter anomalies. Single-point sensors are limited by their installation location and cannot comprehensively reflect the overall condition inside the duct, making them prone to misjudgments due to local data deviations. In addition, traditional monitoring equipment often lacks unified data integration and analysis capabilities, and the monitoring data is scattered and difficult to trace. Once an anomaly occurs, it is impossible to quickly locate the root cause of the problem, which may delay the opportunity to deal with the fault and thus affect the normal operation of the system, and even pose a potential threat to indoor environmental quality and personnel health. To address these issues, we propose a duct operation status monitoring device. Utility Model Content

[0009] Preferably, the duct is composed of two L-shaped sheet metal pieces, the duct is square, and the outer side of the duct is tightly fixed by fixing rings, which are distributed laterally on the outer side of the duct.
[0010] Preferably, the control structure includes a monitor battery, a temperature monitoring module, an air content monitoring module, and a humidity monitoring module. A circuit board is fixedly connected to the top of the mounting plate. A group of symmetrically distributed monitor batteries is fixedly installed on the top of the circuit board.

[0013] Preferably, the heat dissipation structure includes a cooling fan and a ventilation slot. A set of through square slots is provided on the side of the monitor housing.

[0016] Compared with the prior art, this utility model provides a duct operation status monitoring device, which has the following beneficial effects:
[0017] 1. This duct operation status monitoring device integrates a temperature sensor, a humidity sensor, and a content sensor to simultaneously collect key parameters such as temperature, humidity, air composition, and airflow velocity inside the duct. The flow velocity detection holes on the side of the content sensor, together with the I-shaped content monitoring network, form a collaborative structure. This allows for the capture of airflow velocity changes through the flow velocity detection holes and the uniform sampling of air composition through the dense circular holes of the monitoring network, avoiding misjudgments caused by localized data deviations. The top display structure and alarm provide visualization of the monitoring data and proactive early warning. The display screen shows various monitoring parameters in real time, and operators can easily query historical data using operation buttons without relying on external equipment. The alarm integrates a warning horn and multi-color warning lights. The light can immediately issue both audible and visual alarms when parameters exceed thresholds, and different colored warning lights can correspond to different types of anomalies (such as excessive temperature, excessive humidity, etc.), helping staff to quickly identify the type of problem. The air duct is composed of two L-shaped sheet metal pieces, which are tightly fixed on the outside by horizontally linearly distributed fixing rings. This ensures the stability of the air duct structure and facilitates adjustment of the installation position according to site requirements. The mounting plate is connected to the air duct through fixing rings, and the bottom detection structure accurately extends into the central area of the air duct, avoiding monitoring blind spots caused by installation misalignment. In addition, the cooling fan on the side of the monitor housing and the ventilation slot form a convection heat dissipation channel, effectively solving the problem of heat accumulation caused by long-term operation of traditional equipment and extending the service life of electronic components.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 A duct operation status monitoring device, comprising:
[0025] The air duct 1, mounting plate 4, and monitor housing 15 are provided. The top center of the air duct 1 has a mounting groove 3. The mounting plate 4 is fixedly installed inside the fixing ring 2. The monitor housing 15 is fixedly connected to the top of the mounting plate 4. The monitor housing 15 is hollow inside. The side of the monitor housing 15 is provided with a heat dissipation structure. The top of the monitor housing 15 is provided with a display structure.
[0026] The control structure is located on the top of the mounting plate 4, and the control structure is inside the hollow housing 15 of the monitor.
[0027] The detection structure is located at the bottom of the mounting plate 4, inside the air duct 1, and at the center of the bottom of the mounting plate 4.
[0028] Furthermore, the duct 1 is composed of two L-shaped sheet metal pieces. The duct 1 is square in shape, and the outer side of the duct 1 is tightly fixed by fixing rings 2. The fixing rings 2 are distributed horizontally on the outer side of the duct 1. The duct 1 is composed of two L-shaped sheet metal pieces and is square in shape. This structural design not only facilitates factory prefabrication and on-site assembly, reducing the complexity of duct production and installation, but also allows for the adaptation of ventilation requirements of different sizes by adjusting the splicing accuracy of the two L-shaped sheet metal pieces. While the horizontally distributed fixing rings 2 on the outer side tightly fix the duct 1, their spaced distribution characteristics provide multiple optional installation points for the mounting plate 4, enabling the device to flexibly adjust the monitoring position according to the airflow distribution characteristics in the duct, ensuring that the detection structure is always in the optimal area for data acquisition, and avoiding the monitoring limitations caused by a single fixed installation position.
[0029] Furthermore, the control structure includes a monitor battery 6, a temperature monitoring module 7, an air content monitoring module 8, and a humidity monitoring module 9. A circuit board 5 is fixedly connected to the top of the mounting plate 4. A set of symmetrically distributed monitor batteries 6 are fixedly mounted on the top of the circuit board 5. The temperature monitoring module 7, the air content monitoring module 8, and the humidity monitoring module 9 are fixedly mounted between the opposing sides of the two monitor batteries 6. The temperature monitoring module 7 and the humidity monitoring module 9 are located on the outer ends, and the air content monitoring module 8 is located between the temperature monitoring module 7 and the humidity monitoring module 9. The temperature monitoring module 7, the air content monitoring module 8, and the humidity monitoring module 9 are on the same horizontal line. The circuit board 5 serves as the core. The core connecting component not only provides a stable mounting base for the monitor battery 6, temperature monitoring module 7, air content monitoring module 8, and humidity monitoring module 9, but also realizes data interaction and collaborative work between the modules through internal circuitry. The symmetrical installation of the monitor battery 6 ensures the stability of power supply and keeps the center of gravity of the control structure balanced, reducing the shaking caused by uneven force on the mounting plate 4. The layout of the temperature monitoring module 7, air content monitoring module 8, and humidity monitoring module 9 on the same horizontal line shortens the connection path between each module and the circuit board 5, reduces interference during data transmission, and improves the real-time performance and accuracy of parameter analysis.
[0030] Furthermore, the detection structure includes a temperature detector 10, a humidity detector 11, and a humidity detector 12. The temperature detector 10 is fixedly installed at the bottom of the mounting plate 4, directly below the temperature monitoring module 7. The humidity detector 11 is directly below the humidity monitoring module 9. The humidity detector 12 is located between the temperature detector 10 and the humidity detector 11. The orderly distribution of the temperature detector 10, humidity detector 11, and humidity detector 12 at the bottom of the mounting plate 4 (directly below the control structure module) forms a three-dimensional monitoring pattern of "three points in a line". This layout allows the three detectors to collect data at the same cross-section inside the duct 1, ensuring the spatial correlation of temperature, humidity, and air composition parameters. This provides an accurate spatial reference for subsequent analysis of the mutual influence between different parameters (such as the effect of temperature changes on humidity). The humidity detector 12 is located in the middle position and can simultaneously capture the airflow state on both sides, reducing local data differences caused by the dispersed distribution of the detectors.
[0031] Furthermore, the content detector 12 has multiple sets of square flow velocity detection holes 13 on the side near the temperature detector 10. A square groove is also provided on the side of the content detector 12 near the temperature detector 10, within which an I-shaped content monitoring net 14 is fixedly installed. The side of the content monitoring net 14 has horizontally and vertically equidistant and linearly distributed circular holes. The flow velocity detection holes 13 on the side of the content detector 12 are square and multiple in number. The square hole design, compared to circular holes, can more stably capture the turbulent state of the airflow, reducing detection errors caused by airflow impact. The equidistant horizontal and vertical circular holes of the I-shaped content monitoring net 14 form a multi-level air sampling structure, which can simultaneously collect air samples of different heights and widths, avoiding the randomness of single-point sampling and making the air composition monitoring results more representative. The I-shaped structure itself also enhances the mechanical strength of the monitoring net, reducing deformation caused by long-term airflow impact and extending the service life of the detector.
[0032] Furthermore, the heat dissipation structure includes cooling fans 16 and ventilation slots 17. A set of through square slots is opened on the side of the monitor housing 15. The cooling fans 16 are symmetrically distributed and fixedly installed in the square slots on the side of the monitor housing 15. On the other side of the monitor housing 15 corresponding to the square slots, multiple sets of longitudinally linearly distributed ventilation slots 17 are opened, and the ventilation slots 17 penetrate the side wall of the monitor housing 15. The cooling fans 16 on the side of the monitor housing 15 are symmetrically distributed. This layout can form a uniform airflow field inside the housing and avoid local heat dissipation dead zones. The ventilation slots 17 on the other side are longitudinally linearly distributed and penetrate the side wall. Their number and spacing are optimized to ensure sufficient ventilation and prevent external dust and moisture from entering the housing in large quantities through the ventilation slots, thus playing a certain protective role. The convection structure of the cooling fans 16 and ventilation slots 17 can not only exhaust the heat of the control structure, but also reduce the temperature fluctuation inside the monitor housing 15, providing a stable working environment for precision components such as the circuit board 5 and reducing the performance drift of electronic components caused by sudden temperature changes.
[0033] Furthermore, the display structure includes a display screen 18 and operation buttons 19. The display screen 18 is fixedly installed on the top of the monitor housing 15. The display screen 18 is fixedly connected to the top of the monitor housing 15 through the housing. Multiple sets of horizontally linearly distributed operation buttons 19 are fixedly installed on the side of the display screen 18. An alarm 20 is fixedly installed on the top of the monitor housing 15 on the other side where the display screen 18 and operation buttons 19 are installed. The display screen 18 is connected to the monitor housing 15 through an independent housing. This independent housing not only protects the display screen but also isolates the heat conduction inside the monitor housing 15, preventing the display screen from becoming blurry or malfunctioning due to high temperature. The operation buttons 19 are horizontally linearly distributed and set in multiple groups. Each group of buttons corresponds to different operation functions (such as parameter query, threshold setting, historical data export, etc.). The clear layout reduces the probability of misoperation. The alarm 20 is placed on both sides of the display screen 18 and operation buttons 19, avoiding the sound and light interference when the alarm is triggered from affecting the operator's observation of the display screen data. At the same time, its square structure is compatible with the shape of the monitor housing 15, making the overall appearance of the device simpler and easier to integrate into various building environments.
[0034] Furthermore, the alarm 20 is square in shape. A warning horn is located at the end of the alarm 20 closest to the display screen 18, and a warning light is located at the end of the alarm 20 closest to the operation button 19. The warning light consists of multiple different colors. The warning horn and warning light are located at opposite ends of the alarm 20. This separate design allows the audible and visual alarms to propagate in different directions—the warning horn, closer to the display screen 18, prioritizes audible alerts when operators are observing data, while the warning light, closer to the operation button 19, allows operators to visually see the warning color when adjusting parameters. The multi-color warning light design (e.g., red for high temperature, yellow for high humidity, and green for normal conditions) allows for quick differentiation of abnormal types through visual differences. Combined with the audible alarm, this forms a dual alert, effectively improving the transmission efficiency of abnormal information and reducing response delays, especially in noisy industrial environments.

[0056] Working principle: When the device is started, the monitor battery 6 powers the circuit board 5 and each module. The detection structure at the bottom of the mounting plate 4 extends into the central area of the air duct 1 and begins to work. The temperature detection head 10 collects the temperature data inside the air duct 1 in real time and transmits the signal to the corresponding temperature monitoring module 7. The humidity content detection head 11 simultaneously captures humidity information and transmits it to the humidity monitoring module 9. The content detection head 12 located in the middle senses the change in airflow speed through multiple sets of square flow velocity detection holes 13 on the side. At the same time, the I-shaped content monitoring net 14 in the square groove on its side uses the horizontally and vertically equidistantly distributed round holes to detect the change in airflow speed. The system uniformly collects air composition samples, and the relevant data is transmitted to the air content monitoring module 8. Because the temperature monitoring module 7, air content monitoring module 8, and humidity monitoring module 9 work collaboratively on the same horizontal line and are precisely aligned with their corresponding probes, it ensures the synchronous collection and analysis of four parameters: temperature, humidity, air composition, and airflow velocity. This avoids the limitations of traditional single-point monitoring. The monitoring data processed by the control structure is transmitted to the display structure on the top of the monitor housing 15 via the circuit board 5. The display screen 18 presents the values of various parameters in real time. Operators can switch viewing modes or retrieve historical data using the horizontally distributed operation buttons 19, achieving visualization and convenient operation of the monitoring process. When any parameter exceeds the preset threshold, the alarm 20 on the top of the monitor housing 15 immediately responds—the warning horn near the display screen 18 emits an audible alarm, and the multi-color warning light near the operation buttons 19 illuminates the corresponding color according to the type of abnormality (e.g., red for excessive temperature, yellow for excessive humidity). This dual audible and visual warning quickly alerts staff to the problem, solving the problem of lag in traditional manual inspections. During continuous operation, the heat dissipation structure on the side of the monitor housing 15 ensures... To ensure the stable operation of internal components, the symmetrically distributed cooling fans 16 actively draw in external cool air, forming convection with the longitudinally distributed ventilation slots 17 on the other side. This promptly dissipates the heat generated by the control structure's operation, preventing module performance degradation or malfunctions due to high temperatures and extending the equipment's service life. Meanwhile, the horizontally linearly distributed fixing rings 2 on the outside of the duct 1 not only enhance the structural stability of the duct 1, which is composed of two L-shaped sheet metal pieces, but also provide a solid fixing foundation for the mounting plate 4, ensuring that the detection structure is always in the optimal monitoring position in the center of the duct 1, preventing data deviation caused by installation offset.
