[0034] A specific application of this embodiment is:

[0035] During use, the meteorological monitoring unit 31 includes a wind speed sensor, a wind direction sensor, and a meteorological multi-element louver box, which provides meteorological parameters to ensure the accuracy of subsequent data analysis. The dust monitoring unit 21 uses PM2.5 and PM10 sensors to continuously and automatically monitor dust, collects data once per minute, and uploads it to the server for statistics and analysis in real time. The display screen 12 displays the monitoring data in real time, providing a warning function for construction units and urban residents. When the display screen 12 needs to be maintained, rotate the bolt 133 counterclockwise to make it leave the limit lug 15, release the fixation of the annular slider 132, and then push the shielding cover 131 upward. Then, the annular slider 132 slides on the vertical rod 1, and the inner wall of the sliding groove 134 slides on the limit lug 15, which is used to play a limiting role and make the shielding cover 131 move in a straight line. After moving the shielding cover 131 upward, rotate the bolt 133 clockwise to make it contact the limit lug 15 and fix the shielding cover 131. The shielding cover 131 is far away from the display screen 12, which is convenient for the installation and disassembly of the display screen 12. Then, rotate the handle 422 counterclockwise to drive the threaded rod 421 to rotate. The bottom of the threaded rod 421 rotates on the fixed frame 14 through the convex ring 424, and the lifting plate 142 drives the push block 143 to move upward and away from the mounting block 121, thus releasing the fixation of the display screen 12. Then, pulling the display screen 12 can quickly disassemble the display screen 12, which is convenient for subsequent maintenance and other work. The lifting plate 142 slides on the limit rod 423 during movement, which is used to limit the lifting plate 142 and make the lifting plate 142 move in a straight line up and down. Since the display screen 12 is inserted into the fixed plate 141 through the mounting block 121, it can support the display screen 12, so that the display screen 12 does not need to be supported during installation or disassembly, which is more convenient for the staff to operate. When the display screen 12 needs to be installed after the maintenance is completed, insert the display screen 12 into the fixed plate 141 through the mounting block 121, and the fixed convex plate 123 contacts the top of the fixed plate 141. After placing it, rotate the handle 422 clockwise to drive the threaded rod 421 to rotate. Then, the lifting plate 142 drives the push block 143 to move downward. Since the inclined surface groove 122 is opened at the top of the mounting block 121, after the push block 143 enters the inclined surface groove 122, it will push the mounting block 121, making the display screen 12 close to the fixed plate 141 to complete the fixation. Then, rotate the bolt 133 counterclockwise to release the fixation of the shielding cover 131, and pull the shielding cover 131 downward so that the bottom of the annular slider 132 contacts the top of the support ring 16. Then, the shielding cover 131 shields the display screen 12, which can play a certain sunshade role, facilitating people to view better and reducing the occurrence of reflection.
