Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an atmospheric environment monitoring device based on NB-IOT. Background Art

[0002] With the rapid development of society, the exhaust gas discharged by some factories during production will pollute the air and cause varying degrees of damage to the surrounding environment. At this time, special equipment is needed to monitor the air in real time to facilitate the later management of the atmospheric environment. For example, an atmospheric environment monitoring device with the publication number of "CN218239991U" can protect the outside of the air inlet of the air detector through the setting of a protective component, by setting the installation frame in the protective component on the outside of the air inlet of the air detector. The filter net in the installation frame can protect the outside of the air inlet of the air detector, thereby reducing the phenomenon of leaves, packaging bags and relatively large floating flocs in the air falling into the air inlet and causing blockage of the air inlet, so that the air detector can smoothly perform the detection work, and at the same time In the later stage of work, you can directly pull the connecting frame in the protective component to drive the cleaning machine to slide up and down on the inner wall of the installation frame, so that the impurities in the filter can be cleaned smoothly. The whole process is very convenient and fast; by arranging solar panels and micro generators on the support frame, during the later use, when the flowing wind blows the blades and drives the shaft to rotate, the shaft can drive the emblem-shaped generator to generate electricity, and the solar panel can also convert the solar light source into electrical energy and store it in the battery for use by the air detector in the device. There is no need to connect an external power supply, which can not only reduce the difficulty of installation of the device, but also improve the energy utilization rate of the device. However, the atmospheric environment monitoring device still has the following disadvantages during actual use;

[0003] When the above mechanism is in use, the staff pulls the cleaning brush to slide up and down on the inner wall of the installation frame to achieve the purpose of cleaning the impurities in the filter. However, each time the impurities in the filter are cleaned, the staff needs to operate manually, which increases the workload of the staff and is inconvenient for the staff to use, resulting in the inability to automatically clean the impurities in the filter, and the practicality is low.

[0004] Therefore, we proposed an atmospheric environment monitoring device based on NB-IOT, which can solve the above problems well. Utility Model Content

[0032] Embodiment 1: In order to solve the problem that in the prior art, each time the impurities in the filter 13 are cleaned, the staff needs to manually operate, which increases the workload of the staff and is inconvenient for the staff to use, resulting in the impurities in the filter 13 cannot be automatically cleaned, and the practicality is low, the following solution is disclosed, and specific reference is made to Figure 1-Figure 5 As shown, it includes a column 1, a support plate 3 is fixedly mounted on the outer side of the upper end of the column 1, a solar panel 4 is installed on the top of the column 1, and a motor is fixedly connected to the lower part of the column 1;

[0034] During use, the air entering the box 2 is filtered through the filter 13 to prevent impurities in the air from affecting the accuracy of the detection results of the air detector 5. Then, after the filter 13 has been used for a long time, the motor is started, and the motor drives the rotating rod 10 to rotate, so that the rotating rod 10 drives the transmission rod 11 to rotate using the bevel gear set, and at the same time, the transmission rod 11 drives the cross bar 14 to rotate using the pulley assembly. At this time, the cleaning brush 15 rotates and cleans the impurities on the surface of the filter 13, which can prevent the filter 13 from being blocked by impurities and affecting the filtering effect, thereby automatically cleaning the impurities on the surface of the filter 13, and there is no need for subsequent staff to manually clean the filter 13, thereby reducing the workload of the staff.

For details, refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a protective cover 21 is fixed to the top of the support plate 3, and a metal sheet 20 is bolted to the inside of the protective cover 21 at the top of the support plate 3, a cam 16 is fixed to the outer side of the upper end of the rotating rod 10, the cam 16 corresponds to the position of the striking block 18, and the cam 16 is arranged at the upper end of the rotating rod 10, fixed blocks 17 are fixed to the upper sides of the two sides of the column 1, and the insides of the two fixed blocks 17 are penetrated and connected with striking blocks 18, and a return spring 19 is installed between the outer side of the striking block 18 and the inner wall of the fixed block 17, and two metal sheets 20 are symmetrically distributed on the top of the support plate 3, and the positions of the metal sheets 20 and the striking blocks 18 correspond one by one, one end of the striking block 18 extends into the interior of the column 1, and one end of the striking block 18 fits with the outer side of the cam 16;

[0038] When the motor drives the rotating rod 10 to rotate, the rotating rod 10 drives the cam 16 to rotate, so that the cam 16 squeezes the striking block 18 and moves the striking block 18 to strike the metal sheet 20. Then, when the cam 16 does not squeeze the striking block 18, the striking block 18 is reset under the elastic force of the reset spring 19, and the above operation is repeated, so that the striking block 18 strikes the metal sheet 20 reciprocatingly, and the metal sheet 20 makes a sound, which can drive away birds staying on the device and prevent the birds from staying on the device and affecting the monitoring effect. Furthermore, the protective cover 21 can protect the metal sheet 20 to prevent the metal sheet 20 from making a sound due to accidents.
