Once lost or damaged, it is not easy to repair. When air monitoring is carried out on both sides of the road, passing vehicles and airflow colliding with the detection equipment will also cause damage to the detection equipment. Therefore, designing an air detection device that is simple, low-cost and effective is the problem that this application wants to solve. Summary of the invention

[0036] When in use, directly select the lamp posts on both sides of the road, align the arc-shaped side of the horizontally extending bracket 8 with the lamp post, press hard, the touch plate 6 is squeezed by the lamp post and slides horizontally, and the end of the touch plate 6 presses the end of the clamping plate 5, so that the clamping plate 5 is deflected, thereby achieving the effect of the clamping plate 5 sticking to the outside of the lamp post, increasing the friction resistance between the clamping plate 5 and the lamp post; when the clamping plate 5 rotates, the insertion plate 7 loses the supporting force of the clamping plate 5, and is pressed downward under the action of the spring, and the inclined bottom wall of the insertion plate 7 slides downward along the side wall of the clamping plate 5, thereby playing the effect of limiting and fixing the clamping plate 5, avoiding the situation that the touch plate 6 loses the pressure from the lamp post direction and cannot clamp the lamp post again; After the equipment is fixed to the lamp pole, the wind cup 13 is affected by the air flow on the road and rotates.

At the same time, the upper solution and the bottom solution are exchanged, and the chemical reagents fully ensure that the chemical reagents are fully in contact and react, and the color change is more uniform and obvious; part of the gas generated in the annular reagent tube 25 is discharged through the small opening of the gas injection pipe 29 and the small mouth of the ball 31, and the other part is discharged through the exhaust pipe 30 to avoid excessive air pressure in the annular reagent tube 25; when observing, directly observe the transparent part on the side wall of the detection test tube 1, observe the color change of the annular reagent tube 25, and determine the concentration change of the detected gas in the road per unit time according to the depth of the color and the comparison pattern.
