According to current research, the integrated rice-fish farming model can effectively mitigate the impact of greenhouse gas emissions from farmland on the environment. In order to deeply study the greenhouse gas emission patterns and influencing mechanisms of the integrated rice-fish farming system, more and more people are focusing on the greenhouse gas research of the system. In the above research, it is necessary to collect gases in the rice-fish farming system. At present, the traditional static box method is usually used for gas collection. It is mainly to place a closed container in the test area, collect the gas in the container into a sampling bag at intervals, and when the gas in the sampling bag is full, the sampling is completed.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 4 As shown, a portable gas collection device for a rice-fish farming system comprises:

[0037] like Figure 1 , Figure 2 and Figure 8As shown, the main box 4 is provided with a collection mechanism 7 for collecting the gas therein, the collection mechanism 7 includes a guide tube 1 70, the exhaust nozzle 6 is provided with a guide tube 1 70, the tail end of the guide tube 1 70 is provided with a three-way valve 700, the left end of the three-way valve 700 is connected to the guide tube 2 701, and the lower end thereof is connected to an external electric sampling pump, the three-way valve 700 is controlled by an external motor (not shown in the figure), a shunt tube 702 located on the left side of the guide tube 2 701 is fixedly provided on the main box 4 through a connecting plate, a plurality of shunt tubes 703 arranged equidistantly along the length direction of the shunt tube 702 are fixedly and penetrated on the shunt tube 702, a sealing plate 704 is fixedly sleeved on the shunt tube 703, the lower end surface of the sealing plate 704 is provided with a mounting plate 705 which is slidably provided forward and backward, a plurality of collection bags 706 are provided on the mounting plate 705, and a cylindrical structure for mounting on the mounting plate 705 is provided on the upper end of the collection bag 706.

[0038] like Figure 1 , Figure 8 and Fig. 9 As shown, the diverter tube 702 is provided with a collection unit 71 for batch collection, and the collection unit 71 includes a flow control tube 710. The right end surface of the diverter tube 702 slides left and right and is penetrated by the flow control tube 710, and the left end of the flow guide tube 701 slides through the right end surface of the flow control tube 710, and a flow control hole 711 is opened on the flow control tube 710.

[0039] During operation, the box seat 1 is first manually placed in the rice field and supported through the support unit 2, and the rice ears are allowed to pass through the through groove 9. Then, the main box 4 is inserted into the placement groove 3 with the opening facing downward, and the inner cavity of the main box 4 covers the rice ears that have passed through. The arrangement and assembly of the collection device is completed, and the guide pipe 70 is connected to the upper ends of the exhaust nozzle 6 and the three-way valve 700.

[0040] Afterwards, the external motor operates to rotate the valve in the three-way valve 700, so that the guide tube 1 70 is connected to the electric sampling pump. The electric sampling pump operates to extract the gas in the main box 4. Then, the external motor operates again to change the connecting pipeline of the three-way valve 700, so that the guide tube 2 701 is connected to the electric sampling pump. The electric sampling pump pumps the gas extracted therein into the guide tube 2 701. This part of the gas enters the shunt tube 703 through the guide tube 2 701, and the flow control hole 711 on the flow control tube 710 is controlled by the collection unit 71 to be connected with the collection bag 706 on the corresponding mounting plate 705, and this part of the air is pumped into the collection bag 706. Afterwards, the collection bag 706 is replaced by the collection unit 71, and the above operation is repeated after a period of time to pump the gas into another collection bag 706. Therefore, the above operation process can realize the collection of gas in the rice field in different time periods, which is helpful for in-depth research on the greenhouse gas emission law of the integrated rice-fish farming system.

[0041] like Figure 1 , Figure 6 and Figure 7 As shown, the support unit 2 includes a rectangular groove 20, and three circumferentially evenly distributed rectangular grooves 20 are opened at the bottom of the box seat 1. Three support frames 200 are rotatably arranged in the rectangular groove 20 through a connecting shaft, and the three support frames 200 are staggered front and back, and two adjacent support frames 200 are rotatably connected. The section of the lowest support frame 200 away from the box seat 1 is a right triangle, and two support bars 201 are fixedly arranged on the two lower support frames 200.

[0042] like Figure 1 , Figure 6 and Figure 7 As shown, the support unit 2 also includes an L-shaped frame 21, and the upper support frame 200 and the middle support frame 200 are both fixedly provided with the L-shaped frame 21, and a locking column 210 is slidably and penetratedly installed on the L-shaped frame 21, and a locking plate 211 corresponding to the locking column 210 is fixedly provided on the middle support frame 200 and the lower support frame 200. When the locking column 210 cooperates with the locking plate 211, the locking column 210 penetrates the corresponding locking plate 211.

[0043] like Figure 1 , Figure 6 and Figure 7 As shown, the support unit 2 also includes a locking group, and a locking group is commonly provided between the upper support frame 200 and the lower support frame 200 and the box seat 1, and the locking group includes a rubber clamping ball 22, and the end faces of the upper support frame 200 and the lower support frame 200 facing the corresponding inner wall of the rectangular groove 20 are fixedly provided with a plurality of rubber clamping balls 22 extending along the length direction thereof, and the inner wall of the rectangular groove 20 is provided with a clamping groove 220 corresponding to the rubber clamping ball 22.

[0044] When placing the box seat 1, in the initial state, the rubber card ball 22 is located in the corresponding card slot 220, and the support frame 200 is locked in the rectangular slot 20 through the cooperation between the rubber card ball 22 and the card slot 220. Then, the support frame 200 is manually pulled out so that the length directions of the three support frames 200 in the same rectangular slot 20 are collinear, and the locking column 210 is manually moved so that the locking column 210 passes through the corresponding locking plate 211, so that the corresponding three support frames 200 are integrated, and the angles between the support frames 200 in different rectangular slots 20 are obtuse angles, and the support frame 200 is inserted into the rice field, and the box seat 1 is supported by the mutual cooperation of multiple support frames 200.

[0045] The multiple support bars 201 are provided to increase the pressure area between the support frame 200 and the rice field, thereby preventing the support frame 200 from being excessively sunken. Secondly, through the clamping installation process of the rubber clamping ball 22 and the clamping slot 220, the support frame 200 can be easily retracted into the corresponding rectangular slot 20 when the support frame 200 is not in use, thereby improving the convenience of the device and facilitating carrying and transportation.

[0046] like Figure 4 and Figure 5 As shown, a plurality of circumferentially distributed arc grooves 23 are provided at the bottom of the placement groove 3, a locking groove 230 is provided on the inner wall of the arc groove 23, an L-shaped block 231 corresponding to the arc groove 23 is fixedly provided at the bottom of the main box 4, a tightening block 232 is slidably provided on the inner wall of the arc groove 23, the upper end surface of the tightening block 232 is an inclined surface, and the inclined surface is inclined from top to bottom toward the adjacent locking groove 230, and a spring 233 is fixedly provided between the tightening block 232 and the inner wall of the L-shaped groove.

[0047] like Figure 3 and Figure 4 As shown, a rubber sealing ring 24 is fixedly arranged in the placement groove 3, and the inner diameter of the rubber sealing ring 24 is the same as the outer diameter of the main box 4.

[0048] After the main box 4 is inserted into the placement groove 3 and the L-shaped block 231 is located directly above the corresponding arc groove 23, the main box 4 is continued to move downward so that the L-shaped block 231 contacts the inclined surface of the clamping block 232. As the L-shaped block 231 continues to move downward, the clamping block 232 is squeezed and the spring 233 is compressed, and the L-shaped block 231 moves into the arc groove 23, and the main box 4 is rotated forward so that the horizontal section of the L-shaped block 231 rotates into the locking groove 230, that is, the elastic force generated by the deformation of the spring 233 makes the clamping block 232 press against the corresponding L-shaped block 231, completing the placement and locking of the main box 4. Secondly, when the main box 4 needs to be removed later, the main box 4 is rotated in the opposite direction so that the horizontal section of the L-shaped block 231 exits the corresponding locking groove 230, and then the main box 4 is moved up. In summary, through the above placement process, the main box 4 is locked on the box seat 1, thereby improving the stability of the main box 4 during the collection process.

[0049] And in the process of placing the main box 4 mentioned above, the rubber sealing ring 24 is deformed and fits tightly against the main box 4, sealing the inside of the main box 4. Then, pure water is manually poured into the placement groove 3. The pure water accumulates in the placement groove 3 to form a sealed water circle, thereby improving the sealing effect of the main box 4. At the same time, the overall weight of the device is increased by adding the weight of pure water, making the device more stable.

[0050] like Figure 8 and Fig. 9 As shown, the flow control tube 710 is sleeved on the second flow guide tube 701 and passes through the diversion tube 702. The collection unit 71 also includes an electric push rod 72. The electric push rod 72 with an axis extending from left to right is fixedly arranged between the flow control tube 710 and the connecting plate. The inner cavity of the second flow guide tube 701 is connected to the inner cavity of the flow control tube 710, and the flow control hole 711 faces downward.

[0051] like Figure 8 , Fig. 9 and Fig.10As shown, a sealing strip 73 made of rubber is fixedly provided on the lower end surface of the mounting plate 705, and a through opening opposite to the pipe mouth of the shunt pipe 703 is opened on the sealing strip 73. A plurality of plug-in grooves 730 equidistantly arranged from front to back are opened on the mounting plate 705, and the upper end of the collection bag 706 is plugged and installed in the plug-in groove 730. All mounting plates 705 are driven by an external electric guide rod (not shown in the figure) to move forward and backward synchronously.

[0052] like Fig.10 As shown, a V-shaped plate corresponding to the plug-in slot 730 and opening to the right is fixedly provided on the lower end surface of the mounting plate 705, and two arc-shaped strips 74 distributed front and back are fixedly provided on the V-shaped plate, and the right end arc sections of the two arc-shaped strips 74 are made of elastic material.

[0053] During operation, after the main box 4 is placed and installed, the upper inlet nozzle of the collecting bag 706 is manually plugged into the plug-in slot 730 from bottom to top. During this process, the elastic section on the arc strip 74 is deformed, and the elastic force generated by the deformation causes the arc strip 74 to press and clamp the collecting bag 706, completing the plug-in installation of all the collecting bags 706 on all the mounting plates 705 from left to right.

[0054] In the initial state, the plug-in slot 730 on the rear side of the mounting plate 705 is staggered with the corresponding shunt tube 702, and then the collection process is repeated to extract the original gas in the main box 4, and then the external electric guide rod works to drive all the mounting plates 705 to move backward synchronously, and the plug-in slot 730 on the rear side of the mounting plate 705 is connected with the corresponding shunt tube 702 up and down. At this time, the flow control tube 710 is located at the rightmost position, and the flow control hole 711 on the flow control tube 710 is aligned and connected with the plug-in slot 730 on the rightmost mounting plate 705 and the rightmost shunt tube 702. After the above-mentioned gas collection process is carried out and the gas collection of the rearmost collection bag 706 on the rightmost mounting plate 705 is completed, the electric push rod 72 works to push the flow control tube 710 to move left, the flow control hole 711 is offset from the rightmost plug-in socket, and begins to align with the next plug-in hole, so the collection process of the second collection bag 706 from right to left in the last row is carried out. At the same time, the process of sealing the remaining diversion tubes 702 through the flow control tube 710 makes the other collection bags 706 in a sealed state, and the above-mentioned operation is repeated to complete the collection operation in the last row of collection bags 706.

[0055] Afterwards, the external electric push rod 72 works to push all the mounting plates 705 to move continuously backward, so that the second row of collection bags 706 from back to front is located directly below the diversion tube 702. After a specified time, the above collection operation process is repeated to complete the gas collection of this row of collection bags 706. Therefore, the operation process of collecting multiple bags of gas in different time periods is realized.

[0056] like Figure 1 and Figure 2As shown, the collection mechanism 7 also includes a fixing rod 8. Two left-right symmetrical fixing rods 8 are fixedly arranged on the upper end surface of the box seat 1. Two sliding blocks 80 opposite to each other are installed on and through the fixing rod 8. A shielding cover 81 is fixedly arranged between the two upper sliding blocks 80. The two lower sliding blocks 80 are fixedly connected to the main box 4. The fixing rod 8 is thin at the top and thick at the bottom. A solar cell panel 82 is fixedly installed on the upper end of the shielding cover 81.

[0057] It should be noted that the upper sliding block 80 can only slide on the small diameter section of the fixed rod 8, and the lower sliding block 80 can slide on the large diameter section of the fixed rod 8. During operation, when the main box 4 is plugged in and installed, the fixed rod 8 passes through the sliding block 80 on the main box 4, and the fixed rod 8 guides the downward movement and plugging process of the main box 4. At the same time, in the subsequent use process, the main box 4 is fixed and supported by the two fixed rods 8 to improve the stability of the gas collection process. Secondly, after the main box 4 is installed, the shielding cover 81 is manually plugged and installed on the fixed rod 8. The shielding cover 81 is located at the upper end of the main box 4 to shield and protect the air inlet pipe 5 and the exhaust nozzle 6 at the upper end of the main box 4, and the solar cell panel 82 is set to absorb solar energy to generate electricity, and power the electric push rod 72, the external electric push rod 72, the external motor and the electric sampling pump in the device, so as to realize the long-term self-service collection of the single unit.
