[0014] A method for collecting and using greenhouse gases in water temperature research includes the following steps: S1. Select and place: Inject gas into the floating airbag through the air injection pump and the air injection pipe, place the fixed support frame and the floating airbag at the selected position, use the inflated floating airbag for floating treatment, and drive the counterweight cable and the counterweight block to dive by the counterweight motor and the counterweight I-shaped frame to realize the selection and fixation of the equipment; S2. Sample on the water surface: Drive the inner ring special-shaped plate to move by the in-and-out electric slide rail, drive the inner ring double convex plate to move by the lower pressing electric push rod, fit the round cover convex box to the water surface, and use the treatment pipe rack, the relay vacuum barrel, the storage vacuum barrel, the outer discharge evacuation pipe and the outer discharge pump to realize internal vacuum extraction to complete the water surface sampling; S3.

The external thread pipe and the internal thread pipe are spirally separated from each other to realize the operation of taking the storage vacuum barrel. The vacuum gas collection barrel and the exhaust fixed pipe are pulled out from the separation and fixing barrel to realize collection and extraction.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. There is a suction component. The lower piezoelectric push rod drives the inner ring double convex plate to move, and the in-and-out electric slide rail drives the inner ring special-shaped plate to move, adjusting the gas collection positions of multiple round cover convex boxes and accurately fitting the round cover convex boxes to the water surface to achieve stable gas collection, reducing the occurrence of gas overflow. Moreover, the gas collection position can be adjusted during gas collection to disperse multi-point gas collection and ensure the gas collection area. The storage vacuum barrel is embedded inside the isolation protection box by using the external thread pipe and the internal thread pipe. The storage vacuum barrel is emptied by the external discharge pump and the external discharge evacuation pipe. The storage vacuum barrel and the round cover convex box are cooled by the condenser. The gas enters the inner side of the storage vacuum barrel along the round cover convex box, the treatment pipe rack, the relay vacuum barrel, the telescopic fixed pipe and the rigid connecting pipe. The water containing impurities in the gas in the round cover convex box is cooled by the condenser. The treatment motor drives the arc scraping plate to push the condensed water to scrape and separate, reducing the influence of water vapor on gas collection. By using the pressure difference at the positions of the storage vacuum barrel and the relay vacuum barrel, the external mixed gas is continuously injected. Through continuous condensing treatment, the internal pressure is controlled. The control valve is used to control the intake speed to achieve stable gas treatment and injection, avoiding excessive water vapor in the mixed gas affecting the accuracy of detection data. The flow meter, the temperature detector and the pressure detector are used to detect the flow rate, temperature and pressure to achieve stable control and treatment, improving the collection speed and stability.

[0016] 2. A fixed-sampling component is provided. An air injection pump and an air injection pipe are used to inject air into the suspension airbag. The inflated suspension airbag suspends the fixed support frame above the water surface. A counterweight motor and a counterweight I-shaped frame drive a counterweight cable and a counterweight block to dive to the bottom of the water to fix and limit the fixed support frame and the suspension airbag, so as to ensure stable operation of suspension support and positioning restriction, improve the overall stability and firmness, and reduce the occurrence of water ingress at the air intake position due to suspension shaking. A lifting motor and a lifting I-shaped frame drive a support cable and a separation and fixing barrel to dive to the water sampling position. A pressurized injection pipe, a fixed pump and an outer discharge pipe frame are used to drive the water body to flow. The gas in the water is separated through a separation cage and a molecular sieve cylinder to achieve continuous water replacement and gas separation. In combination with an exhaust fixing pipe and a vacuum gas collection barrel for gas collection treatment, underwater gas collection is realized. By using stable positioning support and water circulation and ventilation treatment, stable gas collection treatment is achieved, and the accuracy of collection is improved.

[0017] In summary, through the mutual cooperation of the suction component and the fixed-sampling component, by simultaneously operating surface collection and underwater collection, the greenhouse gases discharged from different positions are extracted to achieve multi-stage collection and sampling. In combination with the suspension component and the fixing component, stable support treatment of the equipment is realized, ensuring the stability of the equipment during sampling and avoiding large fluctuations from affecting the collection speed. Through the mutual cooperation of multiple components, the collection is ensured to be stable and the collection speed is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The working principle and usage process of the present invention: When collecting the greenhouse gas released by the water body, the staff injects air into the suspension airbag 317 using the air injection pump 318 and the air injection pipe 319. The continuous air injection causes the suspension airbag 317 to expand and rise. Place the suspension airbag 317 and the fixed support frame 1 on the water surface to be collected. After the placement is completed, drive the counterweight I-beam frame 314 to rotate along the fixed support frame 1 by the counterweight motor 313. The counterweight I-beam frame 314 drives the counterweight cable 315 to loosen. The counterweight cable 315 moves downward along the fixed support frame 1 and the suspension airbag 317. Use the counterweight cable 315 to drive the counterweight 316 to dive to the bottom of the water to achieve fixed limit for the fixed support frame 1 and the suspension airbag 317, enabling stable operation of suspension support and positioning limit, improving the overall stability and firmness, and reducing the occurrence of water ingress at the air intake position due to suspension shaking; After fixation, the lower piezoelectric push rod 201 drives the inner ring double convex plate 202 to move downward along the fixed support frame 1, and then the inlet and outlet electric slide rail 203 drives the inner ring special-shaped plate 204 to move along the inner ring double convex plate 202 to adjust the distance between multiple round cover convex boxes 205. Then, the lower piezoelectric push rod 201 drives the multiple round cover convex boxes 205 to move downward so that the bottom ends of the round cover convex boxes 205 are immersed under the water surface. After embedding, the hard connecting pipe 212, the external thread pipe 213, the internal thread pipe 218, and the storage vacuum barrel 217 are fixedly connected by means of threaded connection of the external thread pipe 213 and the internal thread pipe 218, and the storage vacuum barrel 217 is embedded inside the isolation protection box 215. The air in the storage vacuum barrel 217 is extracted by the external exhaust pump 220 and the external exhaust evacuation pipe 219 to evacuate the storage vacuum barrel 217 to a vacuum state. At this time, the condenser 216 is started, and the condenser 216 continuously cools the storage vacuum barrel 217 inside the isolation protection box 215. The condenser 216 and the isolation one-way cylinder 206 cool the surface of the round cover convex box 205. At this time, the control valve 221 is opened to open the processing pipe rack 207 and the hard connecting pipe 212. When the round cover convex box 205 is immersed under the water surface, the telescopic fixed pipe 211 is stretched, and the gas discharged from the water surface outside is intercepted by the round cover convex box 205. The gas enters the inside of the round cover convex box 205 along the water surface. At this time, the round cover convex box 205 is cooled by the isolation one-way cylinder 206 and the condenser 216. At this time, the water containing impurities in the gas is condensed and precipitated, and the condensed water adheres to the inner surface of the round cover convex box 205. The processing motor 208 drives the arc scraping plate 209 to push the condensed water along the round cover convex box 205 to scrape it off the surface of the round cover convex box 205. The condensed water drips onto the water surface along the round cover convex box 205. At this time, by using the air pressure difference at the positions of the storage vacuum barrel 217 and the relay vacuum barrel 210, the external mixed gas enters the inside of the relay vacuum barrel 210 along the processing pipe rack 207, and then the mixed gas enters the inside of the storage vacuum barrel 217 along the relay vacuum barrel 210, the telescopic fixed pipe 211, the hard connecting pipe 212, the external thread pipe 213, and the internal thread pipe 218. Through continuous condensation treatment, continuous air intake operation is realized. The temperature at the position of the storage vacuum barrel 217 is viewed in real time through the temperature detector 222, and the internal air pressure is detected by cooperating with the pressure detector 223 to realize stable temperature control. By using air pressure control, the air intake speed is restricted to avoid excessive water vapor contained in the mixed gas, which affects the accuracy of the detection data. By cooperating with the flow meter 224 to detect the flow measurement, stable collection is realized; Driven by the lifting motor 301, the lifting I-shaped frame 302 rotates along the fixed support frame 1, causing the support cable 303 to loosen. The support cable 303 is used to drive the separation and fixing barrel 304 to dive downward into the water along the fixed support frame 1. When the separation and fixing barrel 304 dives to the sampling position, the flow solenoid valve 312 opens the pressurized injection pipe 307 and the exhaust fixing pipe 310. External water enters the inner side of the separation and fixing barrel 304 along the pressurized injection pipe 307. The separation cage 305 intercepts impurities in the water. At this time, the water contacts the separation and fixing barrel 304 and the separation cage 305, and the molecular sieve cylinder 306 separates the gas in the water. At this time, the fixed pump 309 and the external discharge pipe frame 308 pump the water located inside the separation and fixing barrel 304 and discharge the water externally, realizing continuous water replacement and gas separation. The gas enters the inner side of the vacuum gas collection barrel 311 along the exhaust fixing pipe 310, realizing underwater gas collection.
