Description

Technical Field

[0001] The utility model belongs to the technical field of environmental monitoring equipment, and in particular relates to an atmosphere monitoring sampling station. Background Art

[0002] Atmospheric environmental monitoring is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. Information on changes in the concentration of pollutants in the atmosphere at different altitudes is of great significance to the study and control of atmospheric pollution. Atmospheric sampling usually relies on fixed-point monitoring at sampling stations or mobile detection at mobile monitoring stations. However, mobile monitoring stations are usually only suitable for sampling and monitoring of the atmosphere in lower spaces, and are not suitable for high-altitude sampling. Sampling stations can be used for sampling of the atmosphere at high altitudes, but workers need to climb to the sampling location repeatedly to take samples and bring them back to the laboratory for monitoring. The sampling work is cumbersome and the risk factor increases. Utility Model Content

The sampling time is easy to control, and samples can be collected and preserved for multiple times in succession. There is no need for staff to frequently climb for sampling, thus reducing the risk factor.

The key point is that the sampling assembly includes a group of sampling bottles fixedly arranged by means of a support plate array, a sampling drive assembly and a moving assembly that drives the sampling bottles to pass through the sampling drive assembly in sequence. A rubber stopper is arranged at the end of the sampling bottle. The sampling drive assembly includes a base with a track arranged thereon, a driver, a first tube body, and an air pump and a second tube body that are slidably connected to the base by means of the track. The two ends of the first tube body are respectively connected to the air pump and the rubber stopper, and one end of the second tube body is connected to the rubber stopper. The setting direction of the track is parallel to the axis of the rubber stopper. The ends of the first tube body and the second tube body close to the rubber stopper are both needle-shaped.

[0006] The moving assembly comprises a rotating wheel and a group of levers connected to the rotating wheel. The levers are arranged in an array along the rotating wheel and are arranged corresponding to the sampling bottles.

An outlet is arranged at the lower end of the box body, and the sampling bottles on the bottom pallet pass through the sampling drive assembly in sequence with the help of the moving assembly.

[0009] The front and rear ends of the sampling bottle are respectively provided with rubber plugs, and the air pump and the second tube body are respectively arranged on the front and rear sides of the sampling bottle and matched with the two rubber plugs.

The air pump 10 can be an air pump or an air pump. In this embodiment, the air pump 10 is an air pump. The front and rear ends of the sampling bottle 2 are respectively provided with rubber plugs 5. The air pump 10 and the second tube body 11 are respectively provided on the front and rear sides of the sampling bottle 2 and matched with the two rubber plugs 5.

[0018] The support plate 1 is a horizontally placed flat plate, and a plurality of sampling bottles 2 are fixed on the support plate 1 at equal intervals. In this embodiment, four sampling bottles 2 are fixed on each support plate 1. The moving component 4 drives the support plate 1 with the sampling bottles 2 to move a step distance. One of the sampling bottles 2 on the support plate 1 corresponds to the position of the sampling drive component 3. The moving component 4 stops moving, and the driver 8 in the sampling drive component 3 drives the second tube body 11 and the air pump 10 with the first tube body 9 to move toward each other. The needle-shaped ends of the second tube body 11 and the needle-shaped ends of the first tube body 9 are respectively close to the sampling The rubber stoppers 5 at both ends of the sample bottle 2 are inserted, and the air pump 10 works to extract the gas in the sample bottle 2 from the first tube body 9, and the high-altitude atmosphere enters the sample bottle 2 from the second tube body 11. After the air pump 10 works for a period of time, the gas in the sample bottle 2 is completely replaced, and the air pump 10 is turned off; then the moving component 4 is driven in the reverse direction, so that the air pump 10 and the second tube body 11 move in the reverse direction, and the first tube body 9 and the second tube body 11 are extracted from the rubber stopper 5, and the jack on the rubber stopper 5 is automatically closed to prevent the outside gas from entering, and the sample bottle 2 stores the sample collected during this period. When sampling next time, the moving component 4 continues to move, so that the support plate 1 moves a step distance, and the sampling drive component 3 collects gas; continuous sampling can be performed, and sampling can also be performed at intervals; the driver 8, the air pump 10 and the moving component 4 are all remotely controlled by the controller, and sampling can be completed without the need for workers to climb up. After the sampling is completed, the drone can be used to carry a magnet. The support plate 1 is preset with an iron sheet or magnet, so that the magnet on the drone and the iron sheet or magnet on the support plate 1 are attracted to each other, and the support plate 1 with the sampling bottle 2 is removed and sent to the laboratory for monitoring. There is no need for staff to climb up frequently, and they only need to replenish the sampling bottle 2 after all the sampling of the sampling bottle 2 is completed and before the next sampling. The driver 8 in this embodiment is an electric push rod.

[0019] The moving assembly 4 includes a rotating wheel 12 and a group of levers 13 connected to the rotating wheel 12. The levers 13 are arranged in an array along the rotating wheel 12 and are arranged corresponding to the sampling bottle 2. A notch 14 is provided on the support plate 1 at the lower end of the sampling bottle 2. The levers 13 are arranged corresponding to the sampling bottle 2 through the notch 14. The rotating wheel 12 is located below the support plate 1. When the rotating wheel 12 rotates, the levers 13 move the sampling bottle 2, driving the support plate 1 to drive other sampling bottles 2 on it to move forward together. When moving a step, the lever 13 is separated from the sampling bottle 2, and the lever 13 at the rear contacts the next sampling bottle 2. The moving assembly 4 has a simple structure and is easy to control. The distance of movement of the control support plate 1 is fixed, so that the rubber stopper 5 on the sampling bottle 2 corresponds to the position of the first tube body 9 and the second tube body 11. The first tube body 9 and the second tube body 11 are coaxially arranged.

[0020] Furthermore, the sampling assembly also includes a box 15, in which N layers of sampling bottles 2 fixed by means of a pallet 1 are arranged, N is an integer ≥ 1, and in this embodiment, N = 4, and an outlet 16 is arranged at the lower end of the box 15. The sampling bottles 2 on the bottom pallet 1 pass through the sampling drive assembly 3 in sequence by means of the drive of the moving assembly 4. When the bottom pallet 1 is moved to the outside of the box 15 by the moving assembly 4, the upper pallet 1 falls to the bottom layer under the action of gravity, and the moving assembly 4 continues to move the pallet 1 located at the bottom layer of the box 15. Multiple sampling can be achieved.

[0021] According to different sampling sequences, numbers can be affixed to the sampling bottles 2 in advance to facilitate matching the sampling time with the sampled items.

[0022] Furthermore, a containing frame 17 can be set on one side of the box body 15, and an automatic push rod 18 can be set on the other side. The automatic push rod 18 is an electric push rod. When the pallet 1 is located outside the box body 15 and disengaged from the lever 13, and the next pallet 1 moves a step, the automatic push rod 18 pushes the pallet 1 outside the box body 15 into the containing frame 17, thereby reducing resistance to the operation of the lever 13.
