[0027] Referring to Figures 1-3 , an embodiment provided by the present utility model: A gas monitoring device with a collection function includes a fixing frame 1. At the upper end inside the fixing frame 1, a cylinder 8 is fixedly connected. The output end of the cylinder 8 is fixedly connected with a fixing plate 12. At both ends of the fixing plate 12, connecting plates 9 are fixedly connected. In the middle of the two groups of connecting plates 9, a mounting seat 13 is fixedly connected. In the middle of the mounting seat 13, a servo motor 15 is fixedly connected. At the lower ends of the two groups of connecting plates 9, a fixed sleeve 14 is fixedly connected. In the middle of the fixed sleeve 14, an air cylinder 10 is fixedly connected. The output end of the servo motor 15 is fixedly connected with a threaded shaft 16. The lower end of the threaded shaft 16 is rotatably connected inside the air cylinder 10. A fixed disk 17 is threadedly connected to the surface of the threaded shaft 16. The lower end of the fixed disk 17 is fixedly connected with a sealing disk 18. At the quarter points of the fixed disk 17 and the sealing disk 18, limiting blocks are fixedly connected, and the limiting blocks are all slidably connected inside the air cylinder 10. The sealing disk 18 is slidably connected to the surface of the threaded shaft 16.

[0028] At the upper end of the outer surface of the fixing frame 1, a gas detector 2 is fixedly connected. In the middle of the outer surface of the fixing frame 1, a display panel 3 is fixedly connected. Inside the upper end of the fixing frame 1, a control main board 7 is arranged, and the control main board 7 is electrically connected to the gas detector 2, the display panel 3, the air cylinder 8 and the servo motor 15. Through the gas detector 2, the content of various gases in the air can be detected. Both the sealing disc 18 and the limit blocks at the quarter points of the sealing disc 18 are made of rubber material, and the rubber material can prevent air from escaping from the edge of the fixed disc 17 and the sliding grooves of the limit blocks inside the fixing frame 1. On both sides of the upper and lower ends of the fixing frame 1, fixing ears 4 are fixedly connected, and bolts are threadedly connected in the middle of the fixing ears 4. The fixing frame 1 is fixed at a specified position through the bolts. On one side of the lower end of the air cylinder 10, a second air pipe 21 is fixedly connected, and one end of the second air pipe 21 passes through the fixing frame 1. In the middle of the second air pipe 21, a third one-way valve 22 is fixedly connected. Due to the restriction of the third one-way valve 22, air can only enter the inside of the air cylinder 10 from the second air pipe 21. At the lower end of the air cylinder 10, a first air pipe 19 is fixedly connected, and in the middle of the first air pipe 19, a second one-way valve 20 is fixedly connected. Due to the restriction of the second one-way valve 20, air can only flow from the inside of the air cylinder 10 to the outside. At the lower end of the fixing frame 1, a placement groove is arranged, and at the lower end of the placement groove, a fixing seat 5 is fixedly connected. In the middle of the fixing seat 5, a collection bottle 6 is slidably connected. At the upper end of the collection bottle 6, a first one-way valve 11 is fixedly connected. The outer surface diameter of the upper end of the first one-way valve 11 is the same as the inner surface diameter of the lower end of the first air pipe 19. Placing the collection bottle 6 in the middle of the fixing seat 5 can limit the position of the collection bottle 6, align the first air pipe 19 with the first one-way valve 11, and due to the restriction of the first one-way valve 11, gas can only enter the inside of the collection bottle 6 from the outside.

[0029] Working principle: When in use, the fixing frame 1 is fixed at a specified position through the bolts. An empty collection bottle 6 is placed in the middle of the fixing seat 5. Then, the gas detector 2 monitors the gas and continuously records the change in gas concentration. At the same time, the change in gas concentration is recorded on the control main board 7. The control main board 7 is integrated with a storage module and a communication module. Every once in a while, the air cylinder 8 pushes the fixing plate 12 downward. The fixing plate 12 pushes the mounting seat 13 and the fixed sleeve 14 downward through the connecting plate 9, so that the first air pipe 19 is sleeved on the upper end of the first one-way valve 11. The servo motor 15 drives the threaded shaft 16 to rotate clockwise, so that the sealing disc 18 and the fixed disc 17 move upward, enabling air to enter the inside of the air cylinder 10 from the second air pipe 21. After the fixed disc 17 and the sealing disc 18 move to the highest point, the servo motor 15 drives the threaded shaft 16 to rotate counterclockwise, so that the fixed disc 17 and the sealing disc 18 move downward along the threaded shaft 16, and the air inside the air cylinder 10 is pushed into the collection bottle 6 through the first air pipe 19, thus completing the gas collection. Then, the collection bottle 6 can be taken out, and an empty collection bottle 6 can be replaced, waiting for the next gas collection. Gas collection will also be carried out when the change in gas concentration is large. At the same time, the recorded change in gas concentration is transmitted to the total control unit for data processing.
