Description

Technical Field

[0001] This invention relates to the field of air quality monitoring devices, and more particularly to a portable device for real-time monitoring of multi-parameter ambient air quality. Background Technology

[0002] Ambient air quality monitoring has become an important part of public health and environmental protection. Currently, although portable air quality monitoring devices on the market have certain mobile monitoring capabilities, the following technical bottlenecks still exist in practical applications:

[0003] Traditional portable devices often use a single height adjustment or fixed bracket design, which cannot flexibly adjust the sensor position according to complex scenarios (such as corners, vents, and high-altitude work areas). For example, the monitoring height of existing devices is usually limited to 1 to 1.5 meters, which is difficult to cover air sample collection at different altitudes; and the lack of angle adjustment function results in blind spots in data collection when there are obstacles or complex airflow areas, thus limiting the accuracy of monitoring results.

[0004] Most portable devices only support a single pollutant, making it difficult to comprehensively reflect air quality conditions. Furthermore, their low integration and the stacked design of multi-parameter sensors result in bulky devices, making it difficult to balance portability and data acquisition efficiency. Moreover, existing portable devices lack effective sensor protection during transportation or storage: on the one hand, the lack of cushioning structures makes them susceptible to damage from impacts; on the other hand, manual folding is often used for storage, which is complex and time-consuming, and the exposed sensors are vulnerable to dust, moisture, and other environmental factors, shortening the device's lifespan. How to achieve three-dimensional free adjustment of sensors through mechanical structural innovation while simultaneously considering portability, protection, and low power consumption has become a pressing technical challenge in this field. Summary of the Invention

[0005] The present invention proposes a portable device for real-time monitoring of multi-parameter ambient air quality, which solves the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable device for real-time monitoring of multi-parameter ambient air quality includes a housing, a gas sensor, and a particulate matter sensor, and further includes:

[0008] A lifting mechanism, located inside the housing, is used to adjust the height of the gas sensor and the particulate matter sensor. The lifting mechanism includes a linkage plate.

[0009] A flipping mechanism, located on a linkage plate, is used to flip and swing the gas sensor and the particulate matter sensor. A transmission component is provided between the lifting mechanism and the flipping mechanism.

[0010] An extension mechanism, located on the linkage plate, is used to extend the height of the gas sensor and particulate sensor;

[0011] The drive assembly, located at the bottom of the housing, is used to provide power output to the lifting mechanism and the tilting mechanism. One end of the drive assembly is connected to the tilting mechanism.

[0012] Furthermore, the lifting mechanism also includes a double-ended threaded rod rotatably connected to the inside of the housing. The two ends of the double-ended threaded rod are respectively threaded to a first movable plate. Two sets of traction arms are respectively rotatably connected to the two first movable plates. One end of the two sets of traction arms is hinged to a connecting plate. A guide rod is fixedly connected to the inside of the housing. Threaded holes and guide holes are respectively opened on the two first movable plates. The two ends of the double-ended threaded rod are respectively threaded into the inside of the threaded holes, and the guide rod is movably sleeved into the inside of the guide holes.

[0013] Furthermore, the flipping mechanism includes a first threaded rod rotatably connected to the interior of the housing, a second movable plate threadedly connected to the first threaded rod, an extension sleeve block rotatably connected to the second movable plate, an extension block movably fitted inside the extension sleeve block, and a movable opening corresponding to the extension sleeve block and the extension block on the connecting plate, the extension sleeve block and the extension block being movably fitted inside the movable opening, and a first gear fixedly connected to one end of the first threaded rod.

[0014] Furthermore, the extension mechanism includes a linkage frame rotatably connected to the top of the linkage plate. The linkage frame has a first movable cavity inside, and an extension sleeve is rotatably connected inside the first movable cavity. A second threaded rod is threaded inside the extension sleeve. A second gear is fixedly connected to one end of the second threaded rod. A guide plate is fixedly connected to one end of the extension sleeve. A moving groove is opened on one side of the linkage frame corresponding to the guide plate. One side of the guide plate is movably fitted inside the moving groove.

[0015] Furthermore, an arc-shaped rack is fixedly connected to the top of the linkage plate, and a second movable cavity is provided on the linkage frame corresponding to the arc-shaped rack and the second gear. The second gear and the arc-shaped rack are movably sleeved in the second movable cavity, and one side of the second gear meshes with the arc-shaped rack for transmission.

[0016] Furthermore, the bottom of the linkage frame is rotatably connected to one end of the extension block.

[0017] Furthermore, the drive assembly includes a motor frame fixedly connected to the bottom of the housing, a drive motor fixedly connected to the motor frame, and a third gear fixedly connected to the output shaft of the drive motor, one side of which meshes with the first gear for transmission.

[0018] Furthermore, the transmission assembly includes a first pulley fixedly connected to one end of the first threaded rod, a second pulley fixedly connected to one end of the double-ended threaded rod corresponding to the first pulley, and a transmission belt drivingly connecting the outside of the second pulley and the first pulley.

[0019] Furthermore, a cover plate is hinged to one side of the box, and a protective sponge is fixedly connected inside the cover plate. The protective sponge is movably fitted inside the box, and the gas sensor and particulate matter sensor are respectively fixedly connected to the top of the linkage frame.

[0020] Furthermore, multiple constraint straps are fixedly connected to one side of the interior of the box, and hooks are fixedly connected to the other side of the interior of the box corresponding to the multiple constraint straps, with one end of each constraint strap engaging with a hook.

[0021] Compared with existing technologies, the beneficial effects of this invention are:

[0022] This invention provides rapid support and deployment of equipment by installing a lifting mechanism, a flipping mechanism, and an extension mechanism. The lifting mechanism moves the first moving plate by rotating a double-headed threaded rod, and simultaneously moves the connecting plate by lifting via a traction arm. The flipping mechanism moves the second moving plate by rotating the first threaded rod, thereby causing the extension sleeve to flip and move. At the same time, the arc-shaped rack meshes with the first gear, thereby moving the extension sleeve and allowing the gas sensor and particulate sensor to adjust their height.

[0023] This invention provides power output and transmission to the device by installing a drive assembly and a transmission assembly. The drive assembly drives the rotation of the third gear through a drive motor, which in turn drives the rotation of the first threaded rod. The rotation of the first threaded rod drives the double-headed threaded rod to rotate synchronously through a transmission belt.

[0024] In summary, this device can not only quickly adjust the extension height of gas sensors and particulate matter sensors, but also quickly store them, thus ensuring the service life of the gas sensors and particulate matter sensors, while also enhancing the portability of the device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example, refer to Figure 1-10 A portable device for real-time monitoring of multi-parameter ambient air quality includes a housing 1, a gas sensor 8, and a particulate matter sensor 9. It also includes a lifting mechanism 3, a flipping mechanism 4, an extension mechanism 5, and a drive assembly 6. Notably, the gas sensor 8 and the particulate matter sensor 9 can simultaneously monitor parameters such as PM2.5, PM10, SO2, NO2, CO, and O3, providing comprehensive air quality data by simultaneously detecting multiple pollutants.

[0039] The lifting mechanism 3 includes a connecting plate 305 and a double-headed threaded rod 301 rotatably connected to the inside of the housing 1. The two ends of the double-headed threaded rod 301 are respectively threaded to a first moving plate 302. Two sets of traction arms 303 are respectively rotatably connected to the two first moving plates 302. One end of the two sets of traction arms 303 is hinged to the connecting plate 305. A guide rod 304 is fixedly connected inside the housing 1. The two first moving plates 302 are respectively provided with threaded holes and guide holes. The two ends of the double-headed threaded rod 301 are respectively threaded into the inside of the threaded holes, and the guide rod 304 is movably sleeved into the inside of the guide holes.

[0040] It is worth mentioning that during operation: the rotation of the double-ended threaded rod 301 drives the first moving plates 302 at both ends to move smoothly in relative directions along the guide rod 304. The movement of the two first moving plates 302 drives the traction arm 303 to move in relative directions. At the same time, the movement of the traction arm 303 drives the connecting plate 305 to perform height adjustment. The height adjustment of the connecting plate 305 drives the gas sensor 8 and the particulate matter sensor 9 to perform height adjustment.

[0041] The flipping mechanism 4 includes a first threaded rod 401 rotatably connected to the inside of the housing 1. A second movable plate 402 is threadedly connected to the first threaded rod 401. An extension sleeve block 403 is rotatably connected to the second movable plate 402. An extension block 404 is movably fitted inside the extension sleeve block 403. A movable opening is provided on the connecting plate 305 corresponding to the extension sleeve block 403 and the extension block 404. The extension sleeve block 403 and the extension block 404 are movably fitted inside the movable opening. A first gear 405 is fixedly connected to one end of the first threaded rod 401.

[0042] It is worth mentioning that during operation: the rotation of the first threaded rod 401 drives the first moving plate 402 to move, and at the same time drives the extension sleeve block 403 to move synchronously along the moving groove. The movement of the extension sleeve block 403 drives the extension block 404 to swing synchronously. The swing of the extension block 404 drives the gas sensor 8 and the particulate matter sensor 9 to swing synchronously.

[0043] The extension mechanism 5 includes a linkage frame 501 rotatably connected to the top of the linkage plate 305. The linkage frame 501 has a first movable cavity 508 inside. An extension sleeve 503 is rotatably connected inside the first movable cavity 508. A second threaded rod 502 is threaded inside the extension sleeve 503. A second gear 506 is fixedly connected to one end of the second threaded rod 502. A guide plate 504 is fixedly connected to one end of the extension sleeve 503. A moving groove 505 is opened on one side of the linkage frame 501 corresponding to the guide plate 504. One side of the guide plate 504 is movably fitted inside the moving groove 505.

[0044] It is worth mentioning that during operation, the swing of the linkage frame 501 drives the second threaded rod 502 to swing synchronously, and the rotation of the second gear 506 drives the second threaded rod 502 to rotate synchronously. The rotation of the second threaded rod 502 drives the extension sleeve 503 to move smoothly along the moving groove 505 through the guide plate 504. The movement of the extension sleeve 503 drives the gas sensor 8 and the particulate matter sensor 9 to move synchronously. The monitoring height is adjusted by the movement of the gas sensor 8 and the particulate matter sensor 9. The extension mechanism 5 can extend the sensor height to 1.5 times that of conventional equipment through the threaded transmission between the second threaded rod 502 and the extension sleeve 503. Combined with the ±45° swing of the flipping mechanism 4, it is suitable for environmental monitoring at different heights and angles (such as corners, vents, and other complex scenarios).

[0045] The drive assembly 6 includes a motor frame fixedly connected to the bottom of the housing 1. A drive motor 601 is fixedly connected to the motor frame. A third gear 602 is fixedly connected to the output shaft of the drive motor 601. One side of the third gear 602 meshes with the first gear 405 for transmission. The start of the drive motor 601 drives the third gear 602 to rotate. The rotation of the third gear 602 meshes with the first gear 405 for transmission. The rotation of the first gear 405 drives the first threaded rod 401 to rotate synchronously. The drive motor 601 can control the unfolding and retraction of the mechanism with one button, without manual operation, saving 50% of the operation time compared with traditional manual adjustment equipment. At the same time, the drive assembly 6 realizes one-button operation of "unfolding-monitoring-retraction" through the control system. No professional training is required, and ordinary personnel can use it, which lowers the operation threshold compared with traditional equipment.

[0046] A transmission assembly 7 is provided between the lifting mechanism 3 and the tilting mechanism 4. One end of the drive assembly 6 is connected to the tilting mechanism 4. The transmission assembly 7 includes a first pulley 701 fixedly connected to one end of the first threaded rod 401. A second pulley 702 is fixedly connected to one end of the double-ended threaded rod 301 at the same location as the first pulley 701. A transmission belt 703 is connected between the outside of the second pulley 702 and the first pulley 701. The rotation of the first threaded rod 401 drives the first pulley 701 to rotate synchronously. The rotation of the first pulley 701 drives the second pulley 702 to rotate synchronously through the transmission belt 703. The rotation of the second pulley 702 drives the double-ended threaded rod 301 to rotate synchronously. It is worth mentioning that this patent can replace the belt drive with a gear direct drive or a worm gear drive, thereby improving the transmission efficiency and stability.

[0047] In this invention, an arc-shaped rack 507 is fixedly connected to the top of the linkage plate 305. A second movable cavity 509 is provided on the linkage frame 501 corresponding to the arc-shaped rack 507 and the second gear 506. The second gear 506 and the arc-shaped rack 507 are both movably sleeved in the second movable cavity 509. One side of the second gear 506 meshes with the arc-shaped rack 507 for transmission. When the second threaded rod 502 swings, it drives the second gear 506 to swing synchronously and meshes with the arc-shaped rack 507 for transmission. This way, when the second threaded rod 502 swings, it drives the second gear 506 to rotate and simultaneously drives the second threaded rod 502 to rotate synchronously.

[0048] In this invention, the bottom of the linkage frame 501 is rotatably connected to one end of the extension block 404. A cover plate 2 is hinged to one side of the box body 1. A protective sponge 12 is fixedly connected inside the cover plate 2. The protective sponge 12 is movably fitted inside the box body 1. The gas sensor 8 and the particulate matter sensor 9 are fixedly connected to the top of the linkage frame 501 respectively. The protective sponge 12 protects the equipment parts inside the box body 1 from transportation bumps and collisions, and at the same time provides waterproof and dustproof protection for the inside of the box body 1. It ensures the monitoring accuracy of ambient air quality in a humid outdoor environment. Multiple restraint straps 11 are fixedly connected to one side of the inside of the box body 1. Hooks 10 are fixedly connected to the other side of the inside of the box body 1 at the locations corresponding to the multiple restraint straps 11. One end of the multiple restraint straps 11 is engaged with the hooks 10. At the same time, the engagement of the restraint straps 11 with the hooks 10 constrains and limits the structural parts inside the box body 1.

[0049] It is worth mentioning that waterproof strips (such as silicone rubber sealing rings) are added to the interface of the housing 1, and the sensor surface is coated with a nano waterproof coating (such as polytetrafluoroethylene), so that the equipment can reach the IP65 protection level, adapt to harsh outdoor environments, and be carried and operated by a single person, reducing the deployment cost by 60% compared to fixed monitoring stations.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
