The monitoring data for 30 days (including daily average and monthly average values) can be stored. The instrument is equipped with USB and RS485 data transfer interfaces, and the stored data can be transferred to a computer. The instrument is designed to be powered by a rechargeable lithium battery or AC220V.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 and Figure 3 , an embodiment provided by the present invention includes a box body 1. The front part and the middle and rear parts on the left side of the bottom end of the box body 1 are fixedly connected with support foot seats 6, and the front middle part and the rear part on the right side of the bottom end of the box body 1 are fixedly connected with support foot seats 6. The middle and lower part of the front end of the support foot seat 6 is rotatably connected with a support foot shaft 7, and the middle part of the outer side of the support foot shaft 7 is rotatably connected with a support rod 8. The collector turns the support rod 8 at the bottom of the collection box to a vertical state. At the same time, there is a limiting block at the top of the support rod 8 to limit the deviation of the support rod 8, and the limiting block can be fixed with the fixed groove at the bottom of the box body 1 at the same time.

[0032] Referring to Figure 1 - Figure 2 and Figure 3 , a fixed seat 11 is fixedly connected to the middle part on the left side inside the box body 1, and storage seats 26 are fixedly connected to the front and rear ends in the middle of the box body 1. Collection cans 12 are placed inside the fixed seat 11 and the storage seats 26. A can body cover 13 is threadedly connected to the top of the collection can 12. An air inlet pipe 15 is fixedly connected to the middle and upper part of the left end outside the collection can 12, and an air outlet pipe 16 is fixedly connected to the middle and upper part of the right end outside the collection can 12. One end of each of the air inlet pipe 15 and the air outlet pipe 16 is fixedly connected with a one-way valve assembly 17. The main body outside the one-way valve assembly 17 is a valve body 18. Limiting seats 19 are fixedly connected to both the left and right ends inside the valve body 18. A one-way valve ball 20 is slidably connected to the middle left part inside the valve body 18. A return spring 21 is fixedly connected to the right side of the one-way valve ball 20. An air extraction pump 24 is fixedly connected to the right side inside the box body 1. An air suction pipe 23 is fixedly connected to the middle and upper part of the left end of the air extraction pump 24. By controlling the operation panel 25, the air extraction pump 24 is started. At this time, under the action of the one-way valve assembly 17 on the air inlet pipe 15 of the collection can 12, the one-way valve ball 20 inside the one-way valve assembly 17 moves under the action of negative pressure, and then the collected gas enters the collection can 12. After the collection is completed, the negative pressure inside the one-way valve assembly 17 is lost. At this time, the one-way valve ball 20 is under the action of the return spring 21 to prevent external gas from entering the collection can 12, and only the gas at the detection site can be collected. After the collection is completed, it will not be mixed with other gases during the process of sending the sample for inspection, resulting in sample contamination.

[0033] Referring to Figure 1, on the left side at the top of the rear end of the box body 1, there is a fixedly connected hinge 4. A box cover 2 is placed on the top end of the box body 1. On the right side at the bottom of the rear end of the box cover 2, there is a fixedly connected hinge 4. Inside the hinge 4, there is a rotatably connected rotating pin 5. In the middle of the front part of the top end of the box cover 2, there is a fixedly connected handle 3. On the upper middle parts of the left and right sides of the box body 1, there are fixedly connected backpack straps 9. In the middle of the outer side of the backpack strap 9, there is a backpack strap rope 10. In the middle of the top end of the tank body cover 13, there is a fixedly connected lifting handle 14. The intake pipe 15 is a transparent resin glass long pipe, and the end of the pipe body extends below the collected liquid level. The exhaust pipe 16 is a transparent resin glass short pipe, and the end of the pipe body is above the collected liquid level. In the middle of the top end of the air extraction pump 24, there is a fixedly connected operation panel 25. The operation panel 25 includes control buttons and a data feedback display screen. In the middle of the left side of the intake pipe 23, there is a fixedly connected ventilation hose 22. The other end of the ventilation hose 22 is connected to the one-way valve assembly 17. After the collection box is placed at the collection location, the collection personnel open the box cover 2 through the handle 3. Then, unscrew the tank body cover 13 on the collection tank 12, then add the corresponding gas collection reagent into the collection tank 12, then screw on the tank body cover 13. Subsequently, connect the one-way valve assembly 17 on the exhaust pipe 16 to the intake pipe 23 of the air extraction pump 24 through the ventilation hose 22. Subsequently, through the control of the operation panel 25, start the air extraction pump 24.

[0034] Working principle: The detection personnel carry the detection and collection box to the detection and collection location through the backpack strap rope 10. Subsequently, the collection personnel turn the support rod 8 at the bottom of the collection box to the vertical state. At the same time, there is a limiting block at the top end of the support rod 8 to limit the deviation of the support rod 8. The limiting block can also be fixed to the fixed groove at the bottom of the box body 1. After the collection box is placed at the collection location, the collection personnel open the box cover 2 through the handle 3. Then, unscrew the tank body cover 13 on the collection tank 12, then add the corresponding gas collection reagent into the collection tank 12, then screw on the tank body cover 13. Subsequently, connect the one-way valve assembly 17 on the exhaust pipe 16 to the intake pipe 23 of the air extraction pump 24 through the ventilation hose 22. Subsequently, through the control of the operation panel 25, start the air extraction pump 24. At this time, under the action of the intake pipe 15 on the collection tank 12 and the one-way valve assembly 17, the one-way valve ball 20 in the one-way valve assembly 17 displaces under the action of negative pressure, and then the collected gas enters the collection tank 12. After the collection is completed, the one-way valve assembly 17 loses negative pressure. At this time, the one-way valve ball 20, under the action of the return spring 21, prevents external gas from entering the collection tank 12, and only the gas at the detection location can be collected. After the collection is completed, during the process of sending the sample for inspection, it will not be mixed with other gases, causing sample contamination.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
