DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 to Figure 6The embodiment of the utility model provides an air quality collection device for environmental engineering, comprising: a chassis 1, the edge of the chassis 1 is evenly penetrated with fixing holes 2, and the center of the upper surface of the chassis 1 is fixedly connected with a telescopic support rod 3, the top of the telescopic support rod 3 is fixed with a motor box 4, and the connecting end of the motor box 4 is connected with a matching disk 5, the center of the matching disk 5 is fixed with a connecting shaft 6, and the outer wall of the end of the connecting shaft 6 is evenly fixed with a support frame 7, the end of the support frame 7 is fixedly connected with a reinforcement ring 8, and the side of the reinforcement ring 8 away from the end of the support frame 7 is evenly fixed with a connecting rod 9;

[0028] Specifically, the motor box 4 has a built-in motor, the shaft end of the motor is connected to the matching disk 5, which can drive the matching disk 5 to rotate, and then control the frame structure composed of the connecting shaft 6, the supporting frame 7, the reinforcement ring 8 and the connecting rod 9 to achieve rotation. This can increase the contact area between the sampling tube 10 and the air, and enable the sampling tube 10 to collect flowing air, which is more valuable for reference research.

[0029] The ends of the connecting rods 9 are fixed with sampling tubes 10, and the ends of the sampling tubes 10 close to the reinforcement ring 8 are installed with rear seat plates 11. The sampling tubes 10 are all through tubular structures, and the sizes of the rear seat plates 11 and the tube mouths of the sampling tubes 10 match each other. The center of one side of the rear seat plates 11 located inside the sampling tubes 10 is installed with electric telescopic rods 12, and the ends of the electric telescopic rods 12 are fixed with moving plates 13. The outer ring of the moving plate 13 is wrapped with a rubber ring 14, and the outer wall surface of the rubber ring 14 is in close contact with the inner wall surface of the sampling tube 10.

[0030] Specifically, the sampling tube 10 is used for sampling. The sampling tube 10 is connected from front to back and one end is closed by using the rear seat plate 11. In this way, the open end of the sampling tube 10 can allow air to enter. The electric telescopic rod 12 is installed on the rear seat plate 11. The movable plate 13 is driven to move by the electric telescopic rod 12. The rubber ring 14 fills the gap between the movable plate 13 and the inner wall of the sampling tube 10. During the movement of the movable plate 13, the sampling tube 10 collects air. The whole process is similar to that of a syringe. The movable plate 13 is continuously moved toward the rear seat plate 11 to prompt the air to quickly enter the sampling tube 10 and complete the air collection.

[0031] A connecting tube 15 is fixedly connected to the side wall of the sampling tube 10, and an air storage tube 20 is installed on the side of the connecting tube 15 away from the reinforcement ring 8. The adjacent sampling tubes 10 are connected through the connecting tube 15, and an external threaded connection sleeve 16 is fixed to the middle of the outer wall surface of the connecting tube 15, and an air blocking cap 17 is fixedly connected to the end of the external threaded connection sleeve 16, and the air blocking cap 17 is a conical structure. The front and rear outer walls of the air blocking cap 17 are penetrated by air ports 18, and one side edge of the air port 18 is extended to be connected with a rubber cover 19, and the rubber cover 19 covers the outside of the air port 18. An internal threaded connection sleeve 21 is fixed at the connection between the air storage tube 20 and the connecting tube 15, and the thread size between the internal threaded connection sleeve 21 and the external threaded connection sleeve 16 is consistent;

[0032] Specifically, the air entering the sampling tube 10 will directly enter the air storage tube 20 through the connecting tube 15 to complete the storage. The connecting tube 15 is connected and assembled with the air storage tube 20 by utilizing the size matching between the external threaded connecting sleeve 16 thereon and the internal threaded connecting sleeve 21 on the air storage tube 20. The air blocking cap 17 is used to prevent the air from flowing back into the connecting tube 15 after entering the air storage tube 20. The air port 18 opened on the air blocking cap 17 is used for air circulation. When the air enters the air storage tube 20, the rubber cover 19 covering the outside of the air port 18 will be lifted up by the thrust of the air flow. After the air intake is completed, the rubber cover 19 will be covered back on the outside of the air port 18 to seal the air port 18 to prevent the collected air sample from flowing back into the connecting tube 15.

[0033] A fixing plate 22 is fixed at the center of the closed end surface of the air storage cylinder 20, and an air vent 23 is penetrated in the middle of the fixing plate 22, a rubber skin 24 is fixed on the inner side of the air vent 23, and a slit 25 is arranged inside the rubber skin 24, a folding rubber sleeve 26 is fixedly connected above the edge of the air vent 23, and an external sleeve 27 is fixed to the top of the folding rubber sleeve 26, a threaded structure is arranged on the inner side wall of the open end of the external sleeve 27, and an air guide cone 28 is fixed at the center of the connecting end of the external sleeve 27 and the folding rubber sleeve 26;

[0034] Specifically, the air sample in the air storage cylinder 20 can be directly taken out. A folding rubber sleeve 26, an external sleeve 27 and an air guide cone 28 for exporting the gas sample are provided at the closed end of the air storage cylinder 20. The external sleeve 27 is connected to the output pipe by means of the inner wall thread of its open end. By means of the compressibility of the folding rubber sleeve 26, the folding rubber sleeve 26 is pressed downward, and the air guide cone 28 moves downward immediately until the end of the air guide cone 28 breaks through the slit 25 of the rubber skin 24 and extends into the inner side of the air storage cylinder 20. In this way, the external output pipe is connected to the air storage cylinder 20, and the air sample in the air storage cylinder 20 can be exported thereby, which is convenient, fast and time-saving. After the air sample is exported, the folding rubber sleeve 26 is loosened, and the folding rubber sleeve 26 rebounds quickly under the action of its own elasticity, the air guide cone 28 returns to its position, the slit 25 is re-merged, and the inner cavity of the air storage cylinder 20 is re-sealed and airtight, and air sample storage can continue.

[0035] The working principle of the utility model is:

[0036] The collection device can be directly installed at any suitable installation position outdoors. Taking the roof of a car as an example, the chassis 1 is placed on the roof, the fixing holes 2 are penetrated with bolts, and the bolts are tightened to fix the collection device firmly. The rod height of the telescopic support rod 3 is adjusted, and each sampling tube 10 is adjusted to a suitable height. The motor in the motor box 4 is turned on, and the matching plate 5 drives the connecting shaft 6 to rotate. The support frame 7, the reinforcement ring 8 and the connecting rod 9 then rotate together, and each sampling tube 10 rotates synchronously. During the rotation of the sampling tube 10, the electric telescopic rod 12 installed on the rear seat plate 11 is turned on. The mobile plate 13 moves backward through the contraction movement of the electric telescopic rod 12. The seat plate 11 moves in the direction of the movable plate 13, and during the movement of the movable plate 13, the air quickly enters each sampling tube 10, and under the connecting action of the connecting tube 15, the air enters the air storage tube 20 from the external threaded connecting sleeve 16 through the air port 18 on the air blocking cap 17, and the air sample is stored. When taking it, it is only necessary to connect the threaded end of the output pipe to the inner side of the external sleeve 27. After the connection, press the external sleeve 27 downward, the folding rubber sleeve 26 shrinks, and the air guide cone 28 breaks the slit 25 in the rubber skin 24 and enters the air storage tube 20. At this time, the air sample in the air storage tube 20 can be transported out through the output pipe, and the air collection is completed.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
