Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, and in particular relates to a VOC monitoring device based on multi-sensor fusion according to national standards. Background Technology

[0002] In existing air pollution monitoring technologies, the monitoring of volatile organic compounds (VOCs) mainly relies on single sensors or some traditional methods. Although these methods can achieve preliminary detection of VOCs to a certain extent, they have problems such as limited detection range, low accuracy, and weak adaptability to complex environments. For example, although the traditional GC-MS (gas chromatography-mass spectrometry) method has high sensitivity and accuracy, it is difficult to apply to portable or mobile monitoring due to the large size and high cost of the equipment. In contrast, although the single sensor-based method is low in cost and highly portable, its accuracy and reliability are greatly limited due to poor sensor selectivity and large influence of environmental interference. This paper proposes a VOC national standard method monitoring device based on multi-sensor fusion to meet the above requirements.

[0003] Existing VOC monitoring devices based on multi-sensor fusion are assembled from multiple monitoring devices. The installation process is not only cumbersome, but also cannot automatically lock the monitoring devices, thus affecting the installation efficiency and stability of VOC monitoring devices.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1

[0026] This utility model provides a VOC monitoring device based on the national standard method using multi-sensor fusion, such as... Figures 1 to 5 As shown, the system includes: a frame 1, connectors 2, monitoring stations 3, and mounting components. The frame 1 supports the VOC national standard monitoring device. Connectors 2 can be connecting plates, and the number of connectors 2 is the same as the number of monitoring stations 3. Connectors 2 are connected to the frame 1 and are used to support the VOC national standard monitoring device. There are multiple monitoring stations 3, which are gas monitoring devices, temperature monitoring devices, and humidity monitoring devices, respectively. Sensors are fixedly connected to each monitoring station 3. The monitoring stations 3 are movably mounted on the frame 1 for monitoring the surrounding environment. The mounting components include directional wheels 4, guides 5, clamping components 6, pressure switches 7, telescopic components 8, and snap-fit ​​components 9. The directional wheels 4 are rotatably mounted on the monitoring stations 3. The guides 5 are connected to the connectors 2 and can be guide rails. The clamping components 6 consist of clamping plates and... The extrusion rod consists of two parts: an extrusion member 6 connected to the monitoring platform 3, a pressure switch 7 located on the connecting member 2, and a telescopic member 8 located on the telescopic member 8. The telescopic member 8 can be an electric telescopic rod, which is formed by the movable insertion of two rod-shaped objects. The inside is filled with hydraulic oil. The extension and retraction of the two rod-shaped objects are achieved by the pressure and suction of the hydraulic oil. This is existing technology and will not be described in detail here. The pressure switch 7 is electrically connected to the telescopic member 8. The movable end of the telescopic member 8 is driven to connect to the snap-fit ​​member 9. The snap-fit ​​member 9 can be a snap-fit ​​rod. The snap-fit ​​member 9 is movably set on the monitoring platform 3. The telescopic member 8 drives the snap-fit ​​member 9 to move in the vertical direction. The monitoring platform 3 is provided with a snap-fit ​​groove 14. The snap-fit ​​member 9 is movably set in the snap-fit ​​groove 14. The extrusion member 6 is located outside the pressure switch 7 and abuts against the pressure switch 7.

[0027] The installation of monitoring station 3 can be quickly achieved by using the installation components, and the monitoring station 3 can also be automatically locked, which simplifies the installation process of monitoring station 3 and effectively improves the installation efficiency and stability of VOC national standard monitoring device.

[0028] When multiple monitoring stations 3 (gas, temperature, and humidity monitoring devices) need to be installed, first place the monitoring station 3 above the connector 2, then push the monitoring station 3. The monitoring station 3 will drive the bottom directional wheel 4 to move along the guide 5 within the frame 1. The movement of the monitoring station 3 will drive the pressing member 6 to move synchronously. As the monitoring station 3 moves, the monitoring station 3 will drive the bottom pressing member 6 to contact the pressure switch 7 and apply force to the pressure switch 7, causing the pressure switch 7 to be triggered, thereby activating the telescopic member 8. The movable end of the telescopic member 8 will drive the locking member 9 to move upward. As the locking member 9 moves, the locking member 9 will lock into the locking groove 14 of the monitoring station 3, thereby firmly locking the monitoring station 3 in the current position.

[0029] Specifically, multiple connectors 2 are fixedly connected inside the frame 1. A monitoring platform 3 is movably connected inside the frame 1 above the connectors 2. Multiple directional wheels 4 are rotatably connected to the bottom of the monitoring platform 3. A guide 5 is fixedly connected to the top of the connector 2 at the position corresponding to the directional wheels 4. A pressing component 6 is fixedly connected to the bottom of the monitoring platform 3. A pressure switch 7 is fixedly installed at the top of the connector 2 at the position corresponding to the pressing component 6. A telescopic component 8 is fixedly installed at the top of the connector 2 outside the pressure switch 7. A snap-fit ​​component 9 is fixedly connected to the movable end of the telescopic component 8. A snap-fit ​​groove 14 is opened at the bottom of the monitoring platform 3 at the position corresponding to the outer surface of the snap-fit ​​component 9. The outer surface of the snap-fit ​​component 9 is movably connected to the inside of the snap-fit ​​groove 14.

[0030] like Figures 1 to 5 As shown, it also includes a heat dissipation assembly, which includes a fan 10, a heat-conducting component 11, a heat sink 12, and a heat sink 13. There are multiple fans 10, which are located below the front of the monitoring platform 3. The end of the fan 10 near the pressure switch 7 is the air outlet, and the end away from the pressure switch 7 is the air inlet. The fan 10 is set on the connector 2. The top of the heat-conducting component 11 is inserted into the monitoring platform 3. The heat-conducting component 11 is set on the monitoring platform 3. The heat sink 12 is connected to the heat-conducting component 11. The heat-conducting component 11, the heat sink 12, and the heat sink 13 are all made of aluminum. The heat sink 13 is inserted into the heat sink 12. The fan 10 is located outside the heat sink 13. The fan 10 drives the airflow through the heat sink 13. Multiple fans 10 are evenly spaced on the connector 2. The fan 10 is located below the monitoring platform 3. Multiple heat sinks 13 are evenly arranged around the heat sink 12. The heat sink 13 is located below the heat sink 12.

[0031] By using heat dissipation components, the heat dissipation efficiency of the VOC national standard monitoring device can be effectively improved, avoiding heat accumulation problems inside the VOC national standard monitoring device. This not only ensures the working performance of the VOC national standard monitoring device, but also extends its service life.

[0032] In use, when the monitoring station 3 is working, the heat generated is transferred to the heat sink 12 through the heat conduction component 11. Since there are multiple heat sinks 13 connected below the heat sink 12, the heat is then transferred to the multiple heat sinks 13 respectively. Then, multiple fans 10 installed on the connector 2 are started. The airflow is drawn in from the air inlet, accelerated by the fan 10 and blown out from the air outlet, driving the airflow directly through the evenly arranged heat sinks 13, thereby carrying away the heat on the heat sink 12. The heat conduction component 11, the heat sink 12 and the heat sink 13 together form a heat conduction path, which, together with the airflow, achieves rapid heat dissipation.

[0033] Specifically, multiple fans 10 are fixedly installed at one end of the connector 2, and multiple heat-conducting components 11 are inserted inside the bottom of the monitoring platform 3. Heat sinks 12 are fixedly connected to the bottom of the heat-conducting components 11, and multiple heat sinks 13 are fixedly connected to the bottom of the heat sinks 12. The heat sinks 13 are located on the outer side of the extrusion component 6 and on the inner side of the directional wheel 4.

[0034] Working principle: In actual use, when multiple monitoring stations 3 (gas, temperature, and humidity monitoring devices) need to be installed, the monitoring station 3 is first placed on top of the connector 2. Then, the monitoring station 3 is pushed, and the bottom directional wheel 4 of the monitoring station 3 moves along the guide 5 within the frame 1. The movement of the monitoring station 3 will cause the pressing part 6 to move synchronously. As the monitoring station 3 moves, the bottom pressing part 6 will contact the pressure switch 7 and apply force to the pressure switch 7, thereby triggering the pressure switch 7 and activating the telescopic part 8. The movable end of the telescopic part 8 will drive the locking part 9 to move upward. As the locking part 9 moves, the locking part 9 will engage with the locking groove 14 of the monitoring station 3, thereby firmly locking the monitoring station 3 in the current position. This can quickly realize the installation operation of the monitoring station 3 and can also automatically lock the monitoring station 3, simplifying the installation process of the monitoring station 3 and effectively improving the installation efficiency and stability of the VOC national standard monitoring device.

[0035] Then, when the monitoring station 3 is working, the heat generated is transferred to the heat sink 12 through the heat conduction component 11. Since there are multiple heat sinks 13 connected below the heat sink 12, the heat is then transferred to the multiple heat sinks 13 respectively. Then, the multiple fans 10 installed on the connector 2 are started. The airflow is drawn in from the air inlet, accelerated by the fan 10 and blown out from the air outlet, driving the airflow directly through the evenly arranged heat sinks 13, thereby carrying away the heat on the heat sink 12. The heat conduction component 11, the heat sink 12 and the heat sink 13 together form a heat conduction path, which, together with the airflow, achieves rapid heat dissipation. This can effectively improve the heat dissipation efficiency of the VOC national standard method monitoring device, avoid the problem of heat accumulation inside the VOC national standard method monitoring device, not only ensure the working performance of the VOC national standard method monitoring device, but also improve the service life of the VOC national standard method monitoring device.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
