[0042] A ball head 39 is fixed to the bottom end of the guide rod 30; a number of receiving cavities 40 coaxially connected to the corresponding guide holes 26 are evenly provided inside the rotating ring 9; the sealing part 13 includes an arc-shaped plate 41 coaxial with the rotating ring 9; a sealing plug 42 adapted to the open end of the piston cylinder 10 is fixed to the outer peripheral side of the arc plate 41; a ball groove 43 adapted to the corresponding ball head 39 is provided on the inner peripheral side of the arc plate 41; a limiting hole 44 connected to the corresponding ball groove 43 is provided on the outer peripheral side of the arc plate 41; the limiting hole 44 is slidably fitted with the guide rod 30; an extrusion spring 45 sleeved on the corresponding guide rod 30 is fixedly connected between the outer peripheral side of the arc plate 41 and the corresponding receiving cavity 40; an air outlet pipe 46 is provided inside the sealing plug 42; and a stop valve 47 is provided on the air outlet pipe 46.

[0043] Through grooves 48 are symmetrically provided on the side surfaces of the rotating ring 9 on both sides of each piston cylinder 10; guide tubes 49 that slide in cooperation with the through grooves 48 are symmetrically fixed to the outer side surfaces of the arc-shaped plate 41; sliding grooves 50 are symmetrically provided on the side surfaces of the guide tubes 49 near their ends; inclined guide plates 51 are slidably provided in both sliding grooves 50; a connecting spring 52 is fixedly connected between the two inclined guide plates 51; a guide rail is fixed to the inner wall of the sliding groove 50; a guide groove 53 that slides in cooperation with the guide rail is provided on the side surfaces of the inclined guide plates 51.

[0044] Working principle of the second embodiment:

[0045] In the initial state, under the elastic force of the return spring 31, the connecting plate 29 is pressed against the sealing end of the corresponding piston cylinder 10. At this time, the corresponding guide ball 38 is fitted on the outer peripheral side of the guide ring 33; under the elastic force of the extrusion spring 45, the sealing plug 42 on the outer peripheral side of the arc plate 41 is separated from the open end of the corresponding piston cylinder 10, and the elastic diaphragm 11 is in a normal state.

[0046] During the sampling process and when the mobile vehicle moves to the designated monitoring point, the control starts the servo motor 21. The output end of the servo motor 21 is provided with a reducer, thereby driving the gear 22 to rotate slowly, and then driving the ring gear 23 to rotate slowly, driving the piston cylinder 10 on the sampling part 6 to rotate 60 degrees and then stop rotating. A group of piston parts 12 rotate 60 degrees synchronously with the corresponding piston cylinder 10, and the corresponding guide ball 38 slides from the outer peripheral side of the guide ring 33 to the highest point of the curved guide plate 38. In this process, the corresponding guide ball 38 is squeezed and guided by the curved guide plate 38, thereby driving the corresponding piston part 10 to slide and rise along the corresponding piston cylinder 10, so that the piston plate 27 slides and rises along the inside of the corresponding piston cylinder 10, so that the pressure in the area between the piston plate 27 and the elastic diaphragm 11 is reduced. Under the atmospheric force of the external atmospheric pressure, the elastic diaphragm 11 is expanded into the piston cylinder 10, and the air in the monitoring point area enters the expanded elastic diaphragm 11, along with the guide rod 3 The continuous sliding of 0 causes the ball head 39 to slide into the corresponding ball groove 43, and the slide rod 30 slides through the ball head 39 to drive the arc plate 41 to slide in the direction close to the corresponding piston cylinder 10, until the guide tube 49 on the outer peripheral side of the arc plate 41 is inserted into the corresponding through groove 48. The two sets of inclined guide plates 51 are squeezed by the through groove 48 and slide synchronously along the corresponding slide groove 50 to be accommodated in the inside of the guide tube 49, and the connecting spring 52 is compressed. When the inclined guide plates 51 are disengaged from the corresponding through groove 48, the elastic restoring force of the connecting spring 52 drives the two inclined guide plates 51 to slide out from the inside of the guide tube 49. At this time, the sealing plug 42 on the outer peripheral side of the arc plate 41 is inserted into the sealing end of the corresponding piston cylinder 10, and the sampled air is collected between the expanded elastic diaphragm 11 and the sealing plug 42. At this time, the sealing plate 13 is restricted by the two sets of inclined guide plates 51 and will not slide in the opposite direction, preventing the sealing plug 42 from accidentally disengaging from the piston cylinder 10, thereby ensuring the sealing stability of the sampling.

[0047] After the subsequent detection process, after completing the collection of air in multiple groups of monitoring point areas, the corresponding air outlet pipes 46 are connected to the air inlet pipes of the external air quality detector in turn, and the corresponding stop valves 47 are opened. The collected air is sent into the air quality detector through the air outlet pipes 46 for detection. During this process, the sealing part 13 and the corresponding piston cylinder 10 remain relatively stationary to prevent the sealing part 13 from being separated from the active spreading cylinder 10 and being contaminated by external air; repeat the above operations to complete the detection of the air collected in different monitoring point areas, thereby improving the accuracy of environmental monitoring and early warning.

[0048] After completing the air detection, press the two opposite sets of inclined guide plates 51 to retract them into the corresponding conduits 49, thereby releasing the restriction on the conduits 49 and driving the sealing portion 13 to slide back and reset under the elastic restoring force of the extrusion spring 45.

[0049] For example three, please refer to Figure 1-11, this third embodiment makes the following improvements on the basis of the second embodiment. Specifically, an air inlet duct 54 is provided on the other side of the monitoring box 2; the air inlet duct 54 and the ends of the exhaust duct 3 are both provided with filter screens; support legs 55 are symmetrically fixed to the bottom of the monitoring box 2; the support legs 55 are fixedly mounted on the mobile vehicle by fastening bolts; a carbon dioxide meter 56 and a humidity meter 57 are sequentially mounted on the inner wall of the monitoring box 2; a wind direction meter 58 and a wind speed meter 59 are sequentially mounted on the top of the monitoring box 2; a display screen 60 and a controller 61 are sequentially mounted on the side of the monitoring box 2; the output end of the controller 61 is electrically connected to the servo motor 21 and the exhaust fan respectively, and its output end is electrically connected to the carbon dioxide meter 56, the humidity meter 57, the wind direction meter 58, the wind speed meter 59 and the display screen 60 respectively.

[0050] The working principle of the third embodiment of the present invention is as follows: the wind speed meter 59, the wind direction meter 58, the carbon dioxide meter 56 and the humidity meter 57 are used to measure the wind speed, wind direction, carbon dioxide content and humidity respectively; by controlling and starting the exhaust fan 4, the air in the designated monitoring point area is drawn into the monitoring box 2 through the air inlet pipe 54, and the carbon dioxide meter 56 and humidity meter 57 inside the monitoring box 2 measure the carbon dioxide content and humidity in the air.

[0051] By screwing the sampling portion 6 to the end of the exhaust pipe 5, the sampling area of ​​the sampling portion 6 maintains an air flow with a relatively high flow rate, ensuring that the air finally collected is an air sample of the monitoring point area.
