Description

Technical Field

[0001] The invention relates to the technical field of seagrass bed carbon content measurement, in particular to a seagrass bed ecosystem carbon content measurement device. Background Art

[0002] Seagrass is the only type of angiosperm on Earth that can live entirely in seawater. Seagrass grows in large areas to form seagrass beds, which are habitats for marine life and an important food chain. They stabilize the seabed and coastline. In addition, seagrass beds mainly serve as long-term storage carriers of carbon in the carbon cycle. Seagrass absorbs large amounts of carbon dioxide through photosynthesis and stores it in its tissues, which helps reduce the concentration of carbon dioxide in the atmosphere and combat global warming. The measurement of the carbon fixation in seagrass beds can evaluate the carbon fixation capacity of seagrass beds, and then scientifically evaluate their role in the global carbon cycle and climate change mitigation. The quality of the marine environment and climate change can also be monitored based on changes in the carbon fixation of seagrass beds. Therefore, measuring the carbon content of seagrass beds is of great significance.

[0003] Currently, the carbon content of seagrass beds is usually measured on-site by selecting a sampling area based on the growth of the seagrass beds, and quantitatively sampling a unit sampling plot within the area. The fixed area of ​​seagrass samples are then sent for inspection. The seagrass samples are first dried and then burned to form inorganic matter and release carbon dioxide. The carbon content of the quantitative seagrass samples is obtained by detecting the carbon dioxide concentration in the gas after combustion.

[0004] Existing seagrass samples are on the seabed, and the sampling process requires manual diving to collect them. There is a lack of equipment for rapid sampling of seagrass beds on the seabed, and the collected seagrass samples need to be manually transferred to the detection equipment for detection. Many steps in the measurement process rely on manual participation. In areas with large coverage of seagrass beds, multi-point collection and measurement are required to ensure the accuracy of the measurement results. If the measurement steps rely too much on manual operation, it will directly affect the efficiency of measuring the carbon content of the seagrass beds. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The device for measuring the carbon content of a seagrass bed ecosystem provides a collection mechanism, unwinds the first rope roller and the second rope roller, lengthens the first traction rope and the second traction rope, and causes the collection mechanism to descend until it contacts the seagrass bed on the seabed, and the first clamp and the second clamp cover the seagrass bed, and pulls the rotating handle forward, which drives the insert rod to move in the slot, so that the insert rod is pulled out of the roller shaft of the second rope roller, and then the rotating handle is rotated to drive the first rope roller to continue unwinding, so that the first traction rope is lengthened relative to the second traction rope, and the first clamp and the second clamp are rotated downward relative to the central axis by gravity, and the first clamp and the second clamp are closed, and the seagrass sample covered below is cut off and collected inside the first clamp and the second clamp, and then the first rope roller and the second rope roller are driven to rewind to pull out the first clamp and the second clamp as well as the seagrass sample, and the first clamp and the second clamp collect the seagrass sample by a hoisting and hanging method, which can replace the manual diving collection method and complete rapid collection.

[0020] The device for measuring the carbon content of the seagrass bed ecosystem is provided with a winding and transferring mechanism. The rotating shaft is driven to rotate by a rotating motor. The rotating shaft drives the movable disk to rotate 180 degrees on the box body. The movable disk drives the first rope winding roller and the second rope winding roller to rotate. The first rope winding roller and the second rope winding roller pull the collection mechanism to rotate, so that the first clamping bucket, the second clamping bucket and the seagrass samples collected by them are moved to the position above the feeding mechanism, thereby achieving the effect of transferring the collected seagrass samples.

[0021] The carbon content measuring device for the seagrass bed ecosystem is provided with a feeding mechanism. The first clamp and the second clamp fall on the paddle plate after the transfer. The electric push rod is extended to push the cover plate on the opposite side to move, so that the two cover plates are separated from each other, and the cover plate drives the two paddle plates to move away from each other. At the same time, the first clamp and the second clamp gradually move downward with the separation of the paddle plate, until the outer wall of the first clamp and the second clamp contacts the inner wall of the paddle plate, and the top of the paddle plate is stuck under the side ear. At this time, the electric push rod continues to extend to make the paddle plate push the side ear to move, and the side ears on the first clamp and the second clamp move away from each other, driving the first clamp and the second clamp to rotate around the central axis and move away from each other, so that the first clamp and the second clamp are opened to facilitate the seagrass samples collected inside to fall into the drying combustion chamber, so as to achieve the effect of automatically opening the first clamp and the second clamp, so that the collected seagrass samples fall and are put into the next process.

[0022] The device for measuring the carbon content of the seagrass bed ecosystem is provided with a drying mechanism. The seagrass sample put into the drying combustion chamber falls on the curved tube, and heat is generated by the conduction of the electric heating tube. The fan blows air into the curved tube through the ventilation tube. The flowing air discharges the heat generated by the electric heating tube from the air outlet to dry the seagrass sample. After the drying is completed, as the temperature of the electric heating tube increases, the seagrass sample in the dry state burns to form inorganic matter and releases carbon dioxide after reaching the ignition temperature. The flip motor drives the flip shaft to rotate, and the flip shaft drives the curved tube to flip downward 180 degrees, so that the inorganic matter remaining on the curved tube after burning falls, so as to achieve the effect of receiving the seagrass sample and drying it evenly.

[0023] The device for measuring the carbon content of the seagrass bed ecosystem is provided with a waste treatment mechanism. After the carbon content of the seagrass sample is measured, the inorganic substances and carbon dioxide generated by the combustion of the seagrass sample are in a dry combustion chamber. The clarified lime water in the clarified lime water storage tank is passed into the spray pipe through the liquid pipe by a liquid pump. The clarified lime water is sprayed from the nozzle to spray the carbon dioxide in the dry combustion chamber, so that the carbon dioxide and the clarified lime water are fully contacted to form a precipitate, and the carbon dioxide in the air in the dry combustion chamber is washed away. The clarified lime water flushes the burned inorganic substances and the generated precipitate into the waste liquid collection box from the waste outlet, so as to achieve the effect of collecting the inorganic substances after the seagrass sample is measured and purifying the tail gas containing carbon dioxide, thereby avoiding direct emission of carbon dioxide to pollute the air environment and avoiding the carbon dioxide remaining in the dry combustion chamber to affect the measurement accuracy of subsequent samples.

The dial plate 65 is in an arc-shaped plate shape, and the bottom of the dial plate 65 is rotatably connected to the cover plate 64 via the pin shaft 69. When the outer walls of the first clamping bucket 31 and the second clamping bucket 32 ​​contact the inner wall of the paddle plate 65, the top of the paddle plate 65 is stuck under the side ear 35. However, since the lateral movement path of the cover plate 64 to open the feeding port 62 is greater than the movement path of the paddle plate 65 stuck under the side ear 35, the first clamping bucket 31 and the second clamping bucket 32 ​​will be blocked from unfolding. Therefore, by rotating the paddle plate 65 relative to the cover plate 64 around the pin shaft 69, the difference in the movement path of the paddle plate 65 and the cover plate 64 can be balanced, so that after the cover plate 64 fully opens the feeding port 62, the paddle plate 65 pushes the first clamping bucket 31 and the second clamping bucket 32 ​​to fully unfold through the side ear 35.

[0045] Furthermore, the drying mechanism 7 includes a curved tube 71, an electric heating tube 72 is installed inside the curved tube 71, an air outlet 73 is opened on the upper surface of the curved tube 71, and the number of the air outlet 73 is equidistantly arranged on the upper surface of the curved tube 71, and a flip shaft 74 is connected to the middle of the front and rear sides of the curved tube 71, and a third bearing 75 is installed between the end of the flip shaft 74 away from the curved tube 71 and the box body 1, and the flip shaft 74 is rotatably connected to the box body 1 through the third bearing 75, and the flip motor 7 is connected to the rear side of the flip shaft 74 on the rear side of the curved tube 71. 6. The flip motor 76 is installed on the rear side wall of the box body 1. The shaft end of the flip motor 76 is connected to the flip shaft 74. The flip motor 76 is essentially a motor with a forward and reverse circuit, which is used to drive the curved tube 71 to flip and dump the burned seaweed sample. The input end of the curved tube 71 is connected to a ventilation pipe 77. The ventilation pipe 77 is a high-temperature resistant metal hose and has a certain length reserved to avoid being affected when the curved tube 71 rotates. The bottom of the ventilation pipe 77 is connected to a fan 78, which is used to pass the air from the external environment into the curved tube 71 through the ventilation pipe 77.

[0046] Furthermore, the curved tube 71 is a circular tube with a hollow interior and an S-shaped bend. The curved tube 71 is made of copper metal and has good thermal conductivity, so that the seaweed sample falling on the curved tube 71 is heated. The front and rear sides of the curved tube 71 are rotatably connected to the box 1 via the flip shaft 74. The inner cavity of the curved tube 71 is connected to the fan 78 via the ventilation pipe 77. The inner cavity of the curved tube 71 is connected to the drying combustion chamber 4 via the air outlet 73. The fan 78 blows air into the curved tube 71 through the ventilation pipe 77. The flowing air discharges the heat generated by the electric heating tube 72 from the air outlet 73 and dries the seaweed sample. In addition, when the seaweed sample is burned in the drying combustion chamber 4, the fan 78 is connected to an oxygen cylinder, and oxygen is passed into the drying combustion chamber 4 to help the seaweed sample to burn fully, thereby providing a pure oxygen environment for the sample combustion.

[0047] Furthermore, the waste treatment mechanism 12 includes a waste liquid collection box 121, a clear lime water storage box 122 is installed on one side of the waste liquid collection box 121, a liquid pump 123 is installed on the upper surface of the clear lime water storage box 122, a water outlet of the liquid pump 123 is connected to a liquid pipe 124, a spray pipe 125 is connected to the top of the liquid pipe 124, a spray head 126 is installed on the side wall of the spray pipe 125, the clear lime water storage box 122 stores clear lime water, the water inlet of the liquid pump 123 is communicated with the clear lime water storage box 122 through the liquid pipe 124, the water outlet of the liquid pump 123 is communicated with the spray pipe 125 through the liquid pipe 124, and the spray head 126 is installed on the side wall of the spray pipe 125. The shower pipe 125 is installed on the inner wall of the dry combustion chamber 4. The clarified lime water in the clarified lime water storage tank 122 is passed into the shower pipe 125 through the liquid pump 123 through the liquid pipe 124. The clarified lime water is sprayed from the nozzle 126 to spray the carbon dioxide in the dry combustion chamber 4, so that the carbon dioxide and the clarified lime water are fully in contact to form a precipitate, and the carbon dioxide in the air in the dry combustion chamber 4 is washed away. The clarified lime water flushes the burned inorganic matter and the generated precipitate into the waste liquid collection box 121 from the waste outlet, thereby collecting the inorganic matter after the seaweed sample is measured and purifying the exhaust gas containing carbon dioxide.

[0048] The method of using this embodiment is as follows: when the user actually measures the carbon content of the seagrass bed, the user first places the box 1 on the boat, drives the boat to the designated waters where the seagrass bed grows, anchors after determining the collection position, rotates the handle 283, the handle 283 drives the rod 282 to rotate, the rod 282 drives the roller 28 to rotate, the roller 28 drives the first rope roller 25 and the second rope roller 26 to unwind, the first traction rope 210 and the second traction rope 211 are lengthened to make the collection mechanism 3 descend until it contacts the seagrass bed on the seabed, the first clamping bucket 31 and the second clamping bucket 32 ​​cover the seagrass bed, and then pulls the handle 283 forward, the handle 283 drives the rod 282 to move forward in the slot 281, so that the rod 282 is removed from the second rope roller 26. The first rope roller 25 is pulled out from the roller shaft 28 but still in the roller shaft 28 of the first rope winding roller 25, and then the handle 283 is rotated again to drive the first rope winding roller 25 to continue unwinding, so that the first traction rope 210 is lengthened relative to the second traction rope 211. After the first clamping bucket 31 and the second clamping bucket 32 ​​lose the traction effect of the first traction rope 210, they rotate downward relative to the central axis 37 under their own gravity, and the first clamping bucket 31 and the second clamping bucket 32 ​​are closed, and the seaweed sample covered below is cut off and collected inside the first clamping bucket 31 and the second clamping bucket 32. Then the handle 283 is rotated in the opposite direction to drive the first rope winding roller 25 and the second rope winding roller 26 to reel in the first clamping bucket 31, the second clamping bucket 32 ​​and the seaweed sample, and the first clamping bucket 31 and the second clamping bucket 32 ​​drive the seaweed sample to rise. In the process, the seawater in the first clamping bucket 31 and the second clamping bucket 32 ​​is discharged from the water hole 34 and the clamping groove 33, and then the rotating motor 24 is started, the rotating motor 24 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the movable disk 21 to rotate 180 degrees on the box body 1, the movable disk 21 drives the first rope winding roller 25 and the second rope winding roller 26 to rotate, the first rope winding roller 25 and the second rope winding roller 26 pull the collection mechanism 3 to rotate, so that the first clamping bucket 31 and the second clamping bucket 32 ​​carry the collected seaweed samples to the dial plate 65, and the electric push rod 66 is started. The electric push rod 66 extends and pushes the cover plate 64 on the opposite side to move, so that the two cover plates 64 and the dial plate 65 are separated from each other, and at the same time, the first clamping bucket 31 and the second clamping bucket 32 ​​are separated and gradually move downward with the dial plate 65 until the first clamping bucket 31 and the second clamping bucket 32 ​​are separated and gradually move downward until the first clamping bucket 31 and the second clamping bucket 32 ​​are separated and gradually move downward with the dial plate 65. The outer walls of the bucket 31 and the second clamping bucket 32 ​​are in contact with the inner wall of the paddle 65. At this time, the top of the paddle 65 is stuck under the side ear 35. Then the electric push rod 66 continues to extend to make the paddle 65 push the side ear 35 to move. The side ears 35 on the first clamping bucket 31 and the second clamping bucket 32 ​​move away from each other, driving the first clamping bucket 31 and the second clamping bucket 32 ​​to rotate around the central axis 37 and move away from each other to open. The seaweed sample collected inside falls into the drying combustion chamber 4 and falls on the curved tube 71. The electric heating tube 72 is turned on to generate heat. The fan 78 blows air into the curved tube 71 through the ventilation pipe 77. The flowing air discharges the heat generated by the electric heating tube 72 from the air outlet 73. The evenly distributed air outlet 73 evenly dries the seaweed sample. After drying, the temperature of the electric heating tube 72 rises.The seaweed sample in a dry state burns to form inorganic matter and releases carbon dioxide after reaching the ignition temperature, and then the flip motor 76 drives the flip shaft 74 to rotate, and the flip shaft 74 drives the curved tube 71 to flip downward 180°, so that the inorganic matter remaining on the curved tube 71 after burning falls. At this time, the carbon dioxide measuring instrument 13 detects the carbon dioxide concentration in the dry combustion chamber 4, and transmits the detection data and the detection data before combustion to the computer together. The carbon dioxide content of the seaweed sample can be obtained by comparing the two data. After the carbon content is measured, the inorganic matter and carbon dioxide generated by the combustion of the seaweed sample are in the dry combustion chamber 4. The clear lime water in the clear lime water storage tank 122 is passed into the spray pipe 125 through the liquid pipe 124 by the liquid pump 123, and the clear lime water is sprayed from the nozzle 126 to spray the carbon dioxide in the dry combustion chamber 4, so that the carbon dioxide and the clear lime water are fully contacted to form a precipitate, and the carbon dioxide in the air in the dry combustion chamber 4 is washed away, and the burned inorganic matter and the generated precipitate are flushed into the waste liquid collection box 121 from the waste outlet for collection by the clear lime water. ,
