Description

Technical Field

[0001] The utility model relates to the field of air pollution monitoring, in particular to a mobile vehicle-mounted monitoring device for urban air pollution. Background Technique

[0002] Air pollution refers to the phenomenon that the content of some substances in the atmosphere reaches a harmful level, which destroys the ecological system and the conditions for the normal survival and development of human beings, and causes harm to people or objects. Air pollutants enter the atmosphere from anthropogenic sources or natural sources, participate in the atmospheric circulation process, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical sedimentation in the atmosphere. If the output rate is less than the input rate, they will accumulate relatively in the atmosphere, resulting in an increase in the concentration of a certain substance in the atmosphere.

[0003] The air quality in cities is closely related to people's health. Generally, mobile vehicle-mounted monitoring devices are used to monitor the air. At present, the mobile vehicle-mounted air pollution monitoring is generally integrated with the vehicle. When the vehicle breaks down, the monitoring task cannot be completed, and there are also no corresponding measures for the possible impacts of external factors on the monitoring device.

[0004] Based on the above-mentioned deficiencies in the practicality of the device and the lack of corresponding means to deal with irrational external factors, in view of this technical problem, the present application proposes a mobile vehicle-mounted monitoring device for urban air pollution.

First connecting rods 10 are rotatably connected to the top sides of the outer ends of the first connecting rods 17. The bottom sides of the outer ends of the first connecting rods 10 are rotatably connected to the inner ends of the placing plates 20. The middle parts of the inner ends of the first connecting rods 10 are rotatably connected to the outer ends of fixing plates 9 on the left side. The left sides of the outer ends of the first connecting rods 10 are rotatably connected to the inner ends of second fixing blocks 16. The tops of the second fixing blocks 16 are fixedly connected to the bottom ends of the first folding covers 2. The bottom ends of the second connecting rods 18 are rotatably connected to rotating rods 14. The outer ends of the rotating rods 14 are fixedly connected to the inner ends of the placing plates 20.

[0030] Specifically: When monitoring urban air pollution, it is often necessary to use a mobile device to enable the monitoring device to monitor the air quality in different areas. This device is an equipment placed on the top of a sampling vehicle. In the urban environment, there will inevitably be some external factors that affect the monitoring device. When the device is in use, the electric push rods 19 are started, so that the first folding cover 2 and the second folding cover 3 are synchronously folded and retracted on the surface of the monitoring box 1 under the action of the first connecting rod 10, the second connecting rod 12, the first connecting rod 17 and the second connecting rod 18. When encountering extreme weather and unfavorable external factors, the electric push rods 19 are started again to cover the first folding cover 2 and the second folding cover 3 on the top of the monitoring box 1 to protect the gas monitoring device 11.

[0031] Referring to Figures 2-4 The second folding cover 3 acting as a rain shield. First fixing blocks 8 are fixedly connected to the left and right sides of the bottom end of the second folding cover 3. A fixing plate 9 is fixedly connected to the common bottom end of the first fixing blocks 8. Second connecting rods 12 are rotatably connected to the right side of the outer end of the fixing plate 9. The bottom sides of the outer ends of the second connecting rods 12 are rotatably connected to the inner ends of the placing plates 20. Third connecting rods 15 are rotatably connected to the left sides of the outer ends of the fixing plate 9. The left sides of the outer ends of the third connecting rods 15 are rotatably connected to the inner ends of the second fixing blocks 16. A vacuum pump 7 is fixedly connected to the bottom end of the monitoring box 1. A plurality of suction pipes 6 are fixedly connected to the bottom end of the vacuum pump 7. Suction cups 4 are fixedly connected to the bottom ends of the suction pipes 6. A plurality of fixing rods 5 are fixedly connected to the top ends of the suction cups 4. The top ends of the fixing rods 5 are fixedly connected to the bottom end of the monitoring box 1. A gas monitoring device 11 is placed inside the monitoring box 1 for monitoring the pollution particles in the air through the gas monitoring device 11.

[0032] Specifically: when the sample collection vehicle breaks down and there is an air pollution monitoring task that needs to be completed, first clean the roof of the spare vehicle, then place this device on the roof of the spare vehicle. Subsequently, initially press the suction cups 4 by hand to expel a part of the air inside the suction cups 4, and then start the vacuum pump 7 to expel the remaining air inside the suction cups 4 so that the device can be firmly installed on the roof, avoiding the device detaching from the vehicle due to sudden hard braking and unsatisfactory road conditions.

[0033] Working principle: This device is a monitoring device on a mobile monitoring vehicle. Place the whole device on the roof of the monitoring vehicle. After placing the suction cups 4 at the bottom of the monitoring box 1 on the roof surface, slightly press them to expel a part of the air inside the suction cups 4 for a preliminary fixation. Then start the vacuum pump 7 to draw out the air inside the suction cups 4 through the suction pipe 6 so that the device is firmly adsorbed on the roof. In the face of extreme weather, in order to protect the gas monitoring device 11 from being damaged by external factors, control the electric push rod 19 to push the second connecting rod 18, so that the first connecting rod 17 drives the first link 10 to rotate backward. The rotation of the first link 10 will cause the second fixing block 16 and the fixing plate 9 to move backward accordingly. The fixing plate 9 and the second fixing block 16 are connected by a third link 15, and the fixing plate 9 and the placing plate 20 are connected by a second link 12. By using these different links in cooperation, under the driving force of the electric push rod 19, the first folding cover 2 and the second folding cover 3 can be folded and retracted on the top of the monitoring box 1. The synchronous folding of the first folding cover 2 and the second folding cover 3 ensures the equipment safety of the gas monitoring device 11.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
