[0040] Working principle of the present invention: A bottom rotating disk 201 is fixed at the bottom of the middle screw rod 206. The bottom rotating disk 201 and the middle screw rod 206 are rotated. As the middle screw rod 206 rotates, the middle outer ring 219 can move up and down. This can drive the vertical elongation or shortening of the left connecting plate 208 and the right connecting plate 209. Thus, the top main connecting rod 214 and the top auxiliary connecting rod 215 connected to the tops of the left connecting plate 208 and the right connecting plate 209 move up and down, enabling the top cross bar 210 and the top vertical bar 211 to move up and down inside the side rectangular hole 104, and the monitoring device body 203 on the outer moving disk 202 can be lifted. This makes the installation of the monitoring device body 203 convenient without the need for manual climbing.

A silica gel block 306 is installed at the grid of the vertical round bar 301 and the ring 302. A top air inlet cylinder 305 is fixed to the middle of the top column 103. The vertical round bar 301 and the ring 302 are located outside the top air inlet cylinder 305. In the outdoor environment, foreign objects may fall on the outer side of the vertical round bar 301, which will affect the monitoring accuracy of the top air inlet cylinder 305. The fan blade 401 installed at the top of the top column 103 rotates with the wind, driving the rotation of the vertical round bar 301 and the ring 302. This can shake off the foreign objects on the outer sides of the vertical round bar 301 and the ring 302, and at the same time, can shake off the moisture that enters the inside of the vertical round bar 301 and the ring 302 during rain. Since the vertical round bar 301 and the ring 302 are located outside the top air inlet cylinder 305, in the outdoor environment, the humidity in the air will affect the monitoring of ammonia. A silica gel block 306 is provided in the middle of the vertical round bar 301 and the ring 302, which can absorb moisture and then recover dryness under the sun's irradiation. The silica gel block 306 can be used cyclically.
