The present invention belongs to the technical field of environmental monitoring, in particular to an environmental monitoring device for air pollution.
Environmental monitoring is to track the change of environmental quality and determine the level of environmental quality through the detection of the content and emissions of various substances that have an impact on human beings and the environment, so as to provide a basis and guarantee for environmental management, pollution control and other work. In short, environmental monitoring is a precondition for carrying out all environmental work.

In the implementation solution, when the environmental monitoring device for air pollution needs to monitor and use a polluted environment, firstly, the electric push rod 401 is started to drive the rack 1402 to move. Because the rack 1402 and the gear 1403 are engaged, the gear 1403 is driven to rotate. Through the rotation of the gear 1403, the spur gear 404 is driven to rotate. Because the spur gear 404 is engaged with the internal gear 405, the internal gear 405 is driven to rotate. The internal gear 405 drives the rotating disk 406 to rotate synchronously. With the rotation of the rotating disk 406, the limiting rod 408 slides in the limiting groove formed in the rotating disk 406. Then, the limiting rod 408 drives the limiting block 407 to slide in the cross limiting track 409. As the limiting block 407 slides and drives the L-shaped frame 410 to move, the L-shaped frame 410 drives the air intake cover 411 to constantly move out of the monitoring shell 2. After the four groups of air intake covers 411 extend from the monitoring shell 2, a fan structure is formed. When encountering wind, the wind blows the air intake covers 411. Thus, the air intake covers 411 drive the monitoring shell 2 to rotate in the monitoring frame 1, so that the air enters the air intake cover 411 through the air intake holes and is discharged into the monitoring shell 2 through the air intake covers 411. Through monitoring by the environmental monitor 3, on the one hand, the monitoring range can be increased and the accuracy of environmental monitoring can be improved while rotating; and on the other hand, the accuracy of environmental monitoring is not reduced by the random change of the wind direction to avoid affecting the concentration of contents in the collected air, and meanwhile, the flow of the gas is not affected, so that the environmental pollution monitoring efficiency is higher.
When the gas is in contact with the air intake cover 411, the wind direction is partially blocked through the baffle plate 414, and discharged to the position of the filter screen 416 along the diversion grooves 413. The diversion grooves 413 can help to guide the flow of wind and improve the collection efficiency of wind energy. Meanwhile, the air is discharged into the air intake cover 411 through the filter screen 416, and air impurities can be effectively reduced through the filter screen 416, thereby improving the accuracy of environmental monitoring data and further improving the use effect of the device. The air is discharged into the monitoring shell 2 along the air baffle plates 412. The air baffle plates 412 can increase the flow of the air and increase the entry of the air, to avoid air overflow, thereby further improving the use effect of the device and improving the monitoring effect.
In the process that the air intake cover 411 moves in the monitoring shell 2, the air intake cover 411 drives the rack II501 to move synchronously. Because the rack II501 is engaged with the gear II502, the gear II502 is driven to rotate. Through the rotation of the gear II502, the chain mechanism 503 is driven to rotate. with the rotation of the chain mechanism 503, the cleaning rod 505 is driven to rotate. The impurities and dust on the surface of the filter screen 416 can be cleaned up through the cleaning rod 505 to avoid blocking the filter holes of the filter screen 416 by the dust and the impurities, thereby improving the smoothness of air entry, further improving the accuracy of air pollution monitoring data and ensuring the normal operation of the device. The structure is more flexible to use, thereby satisfying the actual use needs. On the other hand, the end grooves of the diversion grooves 413 can be cleaned to avoid blocking the ends of the diversion grooves 413, so as to improve the air intake effect.
When the air intake cover 411 moves in the monitoring shell 2, if the strong magnet II607 corresponds to the strong magnet 1606, the strong magnet II607 and the strong magnet 1606 produce magnetic adsorption through magnetism, and the U-shaped frame 605 is driven to move up. The U-shaped frame 605 drives the sealing plate 602 to slide on the surface of the limiting pin 603. As the sealing plate 602 moves up, the round holes are not sealed. At this time, the exhaust fans 601 are started. As the exhaust fans 601 are started, the residual air in the monitoring shell 2 is discharged from the monitoring shell 2. When the strong magnet I606 is separated from the strong magnet II607, then the magnetism disappears, and the sealing plate 602 is driven to move down through the rebound of the springs 604, to seal the round holes again. Then, the operation of the exhaust fans 601 is stopped. In this process, the previous air inside monitoring shell 2 is discharged, and new polluted air enters the monitoring shell 2 through the air intake cover 411, so that the air that remains inside the monitoring shell 2 is regularly discharged and new air is introduced, which can ensure that each detection is based on fresh air samples, thereby improving the accuracy and the reliability of the data. At the same time, by regularly discharging the residual air and introducing the new air, the dust accumulation inside the device can be reduced, and the risk of device failure can be reduced; and by regularly replacing the air samples, the wear inside the device can be slowed, thereby prolonging the service life of the device. The electric push rod 401 is started for resetting and driving the air intake cover 411 to move into the monitoring shell 2 near the position of the filter screen 416 to avoid air entry. Through the extension and contraction of the air intake cover 411 regularly, air is sampled, so as to prevent rainwater from intruding into the monitoring shell 2 and avoid affecting the service life of the electronic elements of the environmental monitor 3, thereby improving the use effect of the device and satisfying the actual use needs.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention.
