[0021] Secondly, the present utility model will be described in detail with reference to the schematic diagrams.

[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Figures 1 - 4 Shown is a schematic diagram of the entire structure of a new greenhouse gas emission collection device of the present utility model. Please refer to Figures 1 - 4, A new type of greenhouse gas emission collection device according to this embodiment includes a floating platform 100. The floating platform 100 includes a disc-shaped base shell 110 and a floating body 120 installed inside the base shell 110. The central part of the base shell 110 has a through cabin 1101 that penetrates up and down. At the upper end of the base shell 110, a sampling bucket 200 is fixedly installed and covers the through cabin 1101. The bottom opening of the sampling bucket 200 faces the upper part of the through cabin 1101. At the upper end of the sampling bucket 200, an air delivery pipe 300 and an air pump 310 are provided. The intake end of the air pump 310 is connected to the inner cavity of the sampling bucket 200, and the outlet end is connected to the air delivery pipe 300. Along one side of the air delivery pipe 300 in its length direction, there are multiple units of injection pipe valve connectors 320. Each injection pipe valve connector 320 can be independently conducted and closed. The output end of the injection pipe valve connector 320 is also installed and connected with a sampling bottle 320.

[0024] The floating platform 100 further includes a rubber skirt curtain 130 connected to the outer peripheral side of the bottom of the base shell 110, and the rubber skirt curtain 130 adheres to the water surface. Here, the floating platform 100 has a sufficient diameter size to ensure its floating stability on the water surface, and the size can be customized according to actual needs. At the same time, the floating body 120 inside the base shell 110 can use conventional foam boards or air bags as long as it can ensure its stable floating force. The base shell 110, as a hard outer carrier, can be used to install various components required for sampling. In addition, in order to prevent the floating platform 100 from allowing outside air to enter the through cabin 1101 through the bottom of the platform due to water surface turbulence during use, by setting the soft rubber skirt curtain 130, it can form a tight seal around the bottom of the platform under normal circumstances. When the platform sways, the rubber skirt curtain 130 can form free opening and closing by using its soft elastic characteristics and continuously adhere to the water surface, which can effectively prevent outside air from entering and is beneficial to the accurate detection and sampling of water body greenhouse gas emissions.

[0025] It can be understood that during actual use, the floating platform 100 can also be positioned in a certain area of the water body through tools such as ropes to prevent it from floating freely and being lost.

[0026] The outer peripheral side of the bottom of the sampling bucket 200 has a flange 210. A plurality of positioning screw holes 1102 are provided on the upper part of the base shell 110 and around the outer edge of the through cabin 1101. A bolt 220 is connected between the flange 210 and the positioning screw holes 1102. Among them, a sealing ring 140 is also provided on the outer peripheral side of the top of the through cabin 1101. During use, the sampling bucket 200 can be conveniently installed and disassembled with the base shell 110 under the cooperation of the flange 210, the positioning screw holes 1102, and the bolt 220. At the same time, the sealing ring 140 can seal the connection part between the two to prevent outside air from entering and affecting the sampling accuracy.

[0027] The intake end of the air pump 310 has an air extraction pipe 3101 communicating with the inner cavity of the sampling bucket 200, and the outlet end of the air pump 310 has a guide pipe 3102 communicating with the air delivery pipe 300; an exhaust valve 340 is also provided on the air delivery pipe 300. During the sampling process, the air pump 310 can pump the greenhouse gas in the sampling bucket 200 to the air delivery pipe 300 through the air extraction pipe 3101 and the guide pipe 3102, and distribute it to each sampling bottle 330 through the injection pipe valve connector 320;

[0028] It should be noted that since the sampling time periods corresponding to multiple sampling bottles 330 are different, it is necessary to discharge the remaining greenhouse gas in the sampling bucket 200 and the through cabin 1101 before each sampling. When discharging, all the injection pipe valve connectors 320 are in the closed state. The air pump 310 can pump the gas in the bucket to the air delivery pipe 300 and discharge it through the exhaust valve 340. New sampling work can be carried out after at least 10 minutes, thus ensuring the accuracy of sampling; in addition, since the water body contains a large amount of natural gas components such as air, a positive pressure will be automatically formed in the cavity for supplementation after each sampling is completed, and there is no need to worry about the problem of negative pressure formation inside the through cabin 1101. The structure is simple and the design is reasonable.

[0029] The injection pipe valve connector 320 includes a solenoid valve 3201 with an input end communicating with the air delivery pipe 300, an injection pipe 3202 communicating with the output end of the solenoid valve 3201, a cover body 3203 fixed on the outer peripheral side of the outer end of the injection pipe 3202, and an injection needle 3204 with one end fixedly connected to the injection pipe 3202 and the other end inserted into the inner side of the nozzle of the sampling bottle 330. During sampling, the solenoid valve 3201 of the corresponding unit will be turned on and opened. In this way, the gas in the air delivery pipe 300 will enter the injection needle 3204 through the injection pipe 3202, and the gas will be introduced into the sampling bottle 330 by the injection needle 3204; it can be understood that the sampling bottle 330 here can be made of plastic, glass, etc. The end of the bottle body has a nozzle equipped with a rubber stopper, and the structure is similar to a drip bottle. The injection needle 3204 is inserted into the rubber stopper of the nozzle and can be directly pulled out during disassembly. Moreover, in order to ensure the installation stability of the sampling bottle 330 and prevent the bottle body from slipping, the cover body 3203 and the nozzle of the sampling bottle 330 can be threadedly connected, snap-connected, etc., so as to realize the quick disassembly and stable connection of the connector and the sampling bottle 330, and the use operation is very convenient.

[0030] Furthermore, a control box 400 is also provided at the upper end of the sampling bucket 200. The control box 400 at least includes a storage battery and a controller inside. It can be understood that the control box 400 is the energy supply end and control center of this sampling device. The controller can autonomously control the opening and closing and running time of the air pump 310 and the solenoid valve 3201 according to the pre-set program, thus greatly facilitating the sampling and collection work.

[0031] In summary, for a novel greenhouse gas emission collection device according to this embodiment, during use, the sampling device is deployed in a designated monitoring water area by using the floating platform 100. During sampling, the control unit will turn on the air pump 310 and conduct the injection pipe valve connector 320 of the corresponding unit, so that the greenhouse gases in the through cabin 1101 and the sampling bucket 200 can be pumped into the corresponding sampling bottle 330. After sampling, the injection pipe valve connector 320 is closed. Similarly, when sampling at other time periods, the control unit will turn on the corresponding injection pipe valve connector 320 and close other injection pipe valve connectors 320. The entire process does not require manual participation, effectively solving the problems of poor collection effect caused by the heaviness and structural mismatch of the land greenhouse gas emission sampling device.

[0032] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
