[0022] Please refer to Figures 1-5, the present invention provides a technical solution: a bullet-chain propulsion structure for a gas sampling primary component, including a positioning plate 1. Inside the positioning plate 1, a transmission box 2 is fixedly installed. On the side of the positioning plate 1, a number of pre-samplers 5 are arranged through a limiting frame 4. On the side of the transmission box 2, a push rod mechanism is provided and corresponds to the pre-samplers 5 through the push rod mechanism. Inside the limiting frame 4, a transmission mechanism is provided. On the side of the limiting frame 4, a metal cylinder 6 is fixedly installed. A number of pre-samplers 5 respectively correspond to the metal cylinder 6, and a sealing mechanism is arranged inside the metal cylinder 6. The push rod mechanism includes a push rod 3. The end of the push rod 3 is fixedly connected to a push rod cylinder fixedly installed inside the transmission box 2. The other end of the push rod 3 is in contact with the end of the pre-sampler 5. The shape of the push rod 3 is semi-cylindrical, and a connecting rod 301 is slidably installed inside. One end of the connecting rod 301 is fixedly connected to a connecting rod cylinder fixedly installed inside the transmission box 2. The other end of the connecting rod 301 is fixedly installed with a rubber bushing 302 and corresponds to a connecting end 501 provided at the end of the pre-sampler 5 through the rubber bushing 302. Inside the connecting rod 301, a sampling hose 303 is fixedly installed, and the other end of the sampling hose 303 is connected to a negative pressure motor arranged inside the transmission box 2. The transmission mechanism includes a chain 401. The chain 401 is arranged at the central position inside the limiting frame 4, and a number of metal buckles 402 are symmetrically installed on the outside. A number of pre-samplers 5 are respectively fixedly installed on the outside of the chain 401 through the corresponding metal buckles 402. Arc-shaped grooves 403 are opened inside a number of metal buckles 402 and the chain 401. A number of arc-shaped grooves 403 are symmetric with each other and respectively correspond to an ejecting mechanism arranged inside the limiting frame 4. The ejecting mechanism includes a fixing frame 10. The fixing frame 10 is fixedly installed inside the limiting frame 4 through the cooperation of positioning holes 1001 opened on both sides and bolts. Inside the fixing frame 10, an ejecting cylinder 11 is fixedly installed. The end of the ejecting cylinder 11 is fixedly installed with an ejecting rod 1101. The other end of the ejecting rod 1101 is fixedly installed with an ejecting piece 12. A number of ejecting pieces 12 respectively correspond to a number of arc-shaped grooves 403. The sealing mechanism includes a positioning frame 7. The positioning frame 7 is fixedly installed on the side of the metal cylinder 6. Inside the positioning frame 7, a slide plate cylinder 8 is fixedly installed. The end of the slide plate cylinder 8 is fixedly installed with a connecting rod 801 and a slide plate 802 is fixedly installed through the connecting rod 801. The slide plate 802 is slidably installed at the end of the metal cylinder 6 and keeps sealing with the metal cylinder 6. On the side of the metal cylinder 6, a compression airbag 9 is fixedly installed. The compression airbag 9 is communicated with the metal cylinder 6. The installation position of the metal cylinder 6 corresponds to a number of pre-samplers 5 arranged inside the limiting frame 4, and the inner diameter is 1 mm - 3 mm larger than the diameter of the pre-sampler 5. The control elements such as the cylinders and the negative pressure motor mentioned in the text are all existing mechanisms. Among them, multiple cylinders are all controlled by a cylinder controller. The inner diameter of the rubber bushing 302 is the same as the diameter of the connecting end 501 at the end of a number of pre-samplers 5.The connecting rod 301 is slidably installed inside the push rod 3 and is integrally connected through the cooperation of the connecting rod cylinder and the push rod cylinder.

[0023] During use, first, the pre-sampler 5 is batch-fixed to the outside of the chain 401 through the metal buckle 402. When gas collection is required, the push rod cylinder inside the transmission box 2 is used to push the push rod 3 to operate, so that the push rod 3 can move forward to the pre-sampler 5 by pushing. At the same time, through the ejection mechanism inside the limit frame 4, the ejector rod 1101 and the ejector piece 12 are driven by the ejection cylinder 11 to jack up the pre-sampler 5 upward, so that the pre-sampler 5 enters the metal cylinder 6 through the action of the push rod 3 until it contacts the slide plate 802. The air inside the metal cylinder 6 is compressed and enters the compression air bag 9. While the slide plate cylinder 8 and the connecting rod 801 drive the slide plate 802 to slide out, the pre-sampler 5 is pushed to the end of the metal cylinder 6. Then, while controlling the retraction of the push rod 3, the compression air bag 9 is released, so that it realizes the back blowing of compressed air to block the flue gas. Then, the connecting rod cylinder drives the connecting rod 301 to operate, so that it drives the sampling hose 303 inside it to be fixedly connected to the connection end 501 at the end of the pre-sampler 5 through the rubber bushing 302 at the end. The negative pressure motor operates to generate suction to extract the gas in the pipeline for sampling. After completion, the retraction of the push rod 3 drives the pre-sampler 5 to slide back to the initial position until it contacts the ejector rod 1101 and the ejector piece 12 and separates from the rubber bushing 302, completing one sampling. For the second sampling, the chain 401 drives several metal buckles 402 and the pre-samplers 5 inside them to move to a position parallel to the metal cylinder 6, and then the previous collection steps are repeated.
