Description

Technical Field

[0001] This invention relates to a measuring instrument, and more particularly to an instrument for measuring carbon storage and carbon budget in seagrass beds. Background Technology

[0002] The inability to collect water samples, seagrass bed samples, and sediment samples separately or in combination at different time periods affects the monitoring results. Furthermore, the integrated design of the device makes sample extraction inconvenient. Additionally, it is impossible to cleanly count the sediment content during use, resulting in low functionality.

[0003] To address this issue, an instrument for measuring carbon storage and carbon budget in seagrass beds was designed. Summary of the Invention

[0004] The main objective of this invention is to provide an instrument for determining the carbon storage and carbon budget of seagrass beds. By placing a sample container below the inlet pipe, samples can be collected and then sealed. The sample flowing into the container experiences a significant impact, ensuring uniform mixing. A sampling mechanism then extracts water and seagrass bed mixtures. Furthermore, by allowing sediment to settle inside the sample container, and then using the sampling mechanism to separately extract water and seagrass bed samples, three different samples are obtained, resulting in more accurate and practical test results. This is achieved through the use of a flow guide plate. The inner side of the leak is equipped with a barrier mechanism consisting of a hidden groove, a blocking plate, a first spring, a pull rope, and a hollow float. This mechanism automatically seals the top of the sample container after it is filled with sample, facilitating sedimentation and making it more convenient to use. The sampling mechanism is composed of a motor, shaft, turntable, sampling chamber, first support plate, second leak, and a bonding plate and sediment inlet inside the sample container. Two sets of turntables are provided, with the top turntable extending into the interior of the sample container and the bottom turntable fitting below the sediment inlet. By controlling the rotation of the turntables, the supernatant at the top and the bottom can be automatically sampled after sedimentation. The system samples sediment from the sedimentary deposits. After the sample is injected into the sample container, the rotation of the turntable allows for further sampling of the mixture, making sampling more convenient. The sample storage mechanism consists of a pull plate, a second support plate, a geared disc, a shaft, a sampling tube, and gears. The gears are mounted on the shaft and mesh with the outer side of the geared disc. During sampling, the rotation of the sampling tube is automatically controlled, and the tube is automatically replaced. This linkage control simplifies sampling. Furthermore, the separate design of the sample storage mechanism from the main body facilitates the complete retrieval of samples. The sampling tube is more convenient to fill. The discharge mechanism, consisting of a discharge pipe, sliding sleeve, baffle, second spring, through hole and protrusion at the bottom of the sample barrel, can automatically discharge the sample after sampling to facilitate secondary sampling, which is more practical. The sediment content detection mechanism, consisting of a weighing cylinder, drainage pipe, drain pipe, solenoid valve, filter cylinder, filter screen, pad, first pressure sensor, second pressure sensor and hot air blower, can weigh the sample and sediment separately during use, and then calculate the sediment content through the formula, which improves the functionality of the device.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides an instrument for determining carbon storage and carbon balance of seagrass beds. By placing a sample container below the inlet pipe, samples can be collected as surface runoff passes by. After collection, the sample container is sealed. The sample flowing into the sample container has a large impact force, which can ensure uniform mixing of the sample. Then, the sampling mechanism takes samples of the water and seagrass bed mixture. In addition, by allowing sediment to settle inside the sample container, the sampling mechanism takes samples of the water and seagrass bed separately to obtain three different samples, making the test results more accurate and more practical.

[0017] By setting a barrier mechanism consisting of a hidden groove, a blocking plate, a first spring, a pull rope, and a hollow float inside the leakage hole on the guide plate, the top of the sample bucket can be automatically sealed after the sample bucket is filled with sample, so as to carry out sedimentation operation, making it more convenient to use;

[0031] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0032] like Figures 1-8As shown, this embodiment provides an instrument for measuring carbon storage and carbon budget of seagrass beds, including a triangular weir 5 and a flow meter 6 installed on the top of the triangular weir 5. A housing 1 is provided at the end of the triangular weir 5 away from the flow meter 6. An inlet pipe 2 is installed at the end of the housing 1 away from the triangular weir 5. A guide plate 3 is fixed to the top of the housing 1 and fits against the bottom of the inlet pipe 2. A transfer port 4 is opened at the end of the housing 1 away from the inlet pipe 2. A sample container 7 is provided at the top of the housing 1 below the inlet pipe 2. A first leakage hole 13 is opened on the top of the sample container 7 on the barrier mechanism 8. A barrier mechanism 8 is provided on the side of the first leakage hole 13. A sampling mechanism 9 is provided on the side of the sample container 7. A sample storage mechanism 10 is provided inside the housing 1 near the sampling mechanism 9. A discharge mechanism 12 is provided below the sample container 7. A sediment content detection mechanism 11 is provided on the side of the sample container 7 away from the sampling mechanism 9.

[0033] By setting a sample container 7 below the inlet pipe 2, samples can be collected as surface runoff passes by. After collection, the sample container 7 is sealed. The sample flowing into the sample container 7 has a large impact force, which can ensure that the sample is mixed evenly. Then, the sampling mechanism 9 samples the water sample and the seagrass bed mixture. In addition, by allowing sediment to settle inside the sample container 7, the sampling mechanism 9 samples the water sample and the seagrass bed separately, obtaining three different samples, making the test results more accurate and practical. The guide plate 3 is equipped with a hidden groove 14, a blocking plate 15, a first spring 16, a pull rope 17, and a hollow float 18 set inside the leakage hole. The barrier mechanism 8 automatically seals the top of the sample container 7 after it is filled with sample, facilitating sedimentation and making it more convenient to use. The sampling mechanism 9 consists of a motor 20, shaft 21, turntable 22, sampling chamber 23, first support plate 24, second leak hole 25, and an internal fitting plate 26 and sediment inlet 27 within the sample container 7. Two sets of turntables 22 are provided, with the top turntable extending into the sample container 7 and the bottom turntable fitting below the sediment inlet 27. By controlling the rotation of the turntables 22, the supernatant at the top and the sediment at the bottom can be automatically sampled after sedimentation. This process is also possible when the sample is just injected into the sample container. After entering the sample container 7, the mixture can be sampled by controlling the rotation of the turntable 22, making sampling more convenient. The sample storage mechanism 10, composed of a pull plate 28, a second support plate 29, a geared disc 30, a shaft 21, a sampling tube 32, and a gear 33, has the gear 33 mounted on the shaft 21 and meshing with the outer side of the geared disc 30. During sampling, the rotation of the sampling tube 32 is automatically controlled, and the sampling tube 32 is automatically replaced. This linkage control simplifies sampling. Furthermore, the separate design of the sample storage mechanism 10 and the housing 1 facilitates the complete retrieval of samples, and the loading of the sampling tube 32 is more convenient. The discharge mechanism 12, consisting of a discharge pipe 34, a sliding sleeve 35, a partition 36, a second spring 37, a through hole 38, and a protrusion 39, is installed at the bottom of the sample container 7. After sampling is completed, the sample can be automatically discharged for secondary sampling, which improves its practicality. The sediment content detection mechanism 11, consisting of a weighing cylinder 40, a drainage pipe 41, a drain pipe 42, a solenoid valve 43, a filter cylinder 44, a filter screen 45, a pad 46, a first pressure sensor 47, a second pressure sensor 48, and a hot air blower 49, can weigh the sample and sediment separately during use, and then calculate the sediment content using a formula, which improves the functionality of the device.

[0034] In this embodiment, the blocking mechanism 8 includes a hidden groove 14, a blocking plate 15, a first spring 16, a pull rope 17, and a hollow float 18. The hidden groove 14 is provided on the side of the first leak hole 13 near the liquid inlet pipe 2. The blocking plate 15 is slidably installed inside the hidden groove 14. The first spring 16 is provided between the end of the blocking plate 15 and the inner end of the hidden groove 14. The pull rope 17 is fixed to the end of the blocking plate 15 near the first spring 16. The pull rope 17 passes through the inside of the first spring 16 and through the guide plate 3 to the inside of the sample barrel 7. The hollow float 18 is fixed to the end of the pull rope 17 away from the blocking plate 15. The weight of the hollow float 18 is greater than the sum of the elastic force of the first spring 16 when it is reset and the friction force between the ground of the blocking plate 15 and the top of the hidden groove 14.

[0035] Local working principle: The hollow float 18 is located inside the sample container 7 and is always suspended above the liquid surface. When the bottom of the sample container 7 is in the open state, the rate at which the liquid enters the sample container 7 is less than the rate at which it exits. At this time, the hollow float 18 is always located at the bottom of the sample container 7, and the blocking plate 15 is hidden inside the hidden groove 14. When the bottom of the sample container 7 is in the blocked state, as the liquid level rises, the hollow float 18 will also rise. At this time, the blocking plate 15 will reset under the elastic force of the first spring 16, sealing the top of the sample container 7 to facilitate the settling operation.

[0036] In this embodiment, a guide rod 19 is vertically installed inside the sample container 7, and the hollow float 18 is slidably connected to the guide rod 19.

[0037] Local working principle: The use of guide rod 19 can limit the position of hollow float 18 and prevent the shaking of hollow float 18 from affecting the sampling.

[0038] In this embodiment, the sampling mechanism 9 includes a motor 20, a shaft 21, a turntable 22, a sampling chamber 23, a first support plate 24, a second leakage hole 25, a bonding plate 26, and a mud and sand outlet 27. The motor 20 is installed at the bottom of the housing 1. The output end of the motor 20 is vertically mounted on the shaft 21. The top and middle positions of the shaft 21 are horizontally fixed with the turntable 22. The top of the turntable 22 is symmetrically provided with sampling chambers 23. The turntable 22 at the top of the shaft 21 extends into the interior of the sample container 7. The turntable 22 at the bottom is attached to the bottom of the sample container 7. The outer side and bottom of the sample container 7 are fixed with a first support plate 24. The turntable 22 is attached to the surface of the first support plate 24. The end of the first support plate 24 away from the sample container 7 is provided with a second leakage hole 25 that cooperates with the sampling chamber 23. The sample storage mechanism 10 is located below the second leakage hole 25. The inner top of the sample container 7 is fixed with a bonding plate 26 that is attached to the top of the turntable 22. The bottom of the sample container 7 is provided with a mud and sand outlet 27 that cooperates with the sampling chamber 23.

[0039] Local working principle: When not sampling, the sampling chamber 23 on the turntable 22 is not connected to the interior of the sample container 7. The sampling chambers 23 on the two sets of turntables 22 are located on the same vertical line. After the turntable 22 rotates 180 degrees, the position of the sampling chamber 23 can be changed to perform a sampling operation. During the sampling process, the samples at the top and bottom of the sample container 7 are injected into the sampling chambers 23 on the two sets of turntables 22 respectively to perform the sampling operation. During the sampling of the mixed liquid, two samples are extracted at a time, which can be compared and analyzed. The samples extracted after sedimentation are the separated water sample and the sediment sample. The extraction of multiple samples can ensure the accuracy of the detection.

[0040] In this embodiment, a sealing ring is fixed to the outer side of the bottom end of the sampling cavity 23, and the bottom of the sealing ring is in contact with the first support plate 24.

[0041] Local working principle: The use of sealing rings prevents sample leakage and ensures the amount of sample extracted.

[0042] In this embodiment, the sample storage mechanism 10 includes a pull plate 28, a second support plate 29, a gear 30, a storage slot 31, a sampling tube 32, and a gear 33. The pull plate 28 is attached to the surface of the housing 1. The second support plate 29 is horizontally fixed to the inner side of the pull plate 28. The second support plate 29 is slidably connected to the housing 1. The top of the second support plate 29 is rotatably mounted with a gear 30. The top of the gear 30 is rotatably mounted with a storage slot 31. The sampling tube 32 is vertically inserted into the inside of the storage slot 31. The top of the sampling tube 32 is aligned with the bottom of the second leak hole 25. The gear 33 is mounted on the shaft 21 and meshes with the outer side of the gear 30.

[0043] Local working principle: The sample storage mechanism 10 adopts a pull-out design, which can be pulled out from the inside of the box 1 for sample retrieval and quick filling of the sampling tube 32. During the rotation of the shaft 21, the rotation of the gear 33 is controlled simultaneously. The rotation of the gear 33 drives the rotation of the gear disk 30. During the sampling process, the position adjustment of the sampling tube 32 is automatically controlled to ensure that the sampling tube 32 receives the sample. The linkage control method makes the control more convenient and the practicality higher.

[0044] In this embodiment, four sets of sampling tubes 32 are provided, and the sampling tubes 32 are arranged in a ring array. The circumference of the gear 33 is half the circumference of the gear disk 30.

[0045] Local working principle: After the turntable 22 rotates 180 degrees, the position of the sampling tube 32 will rotate 90 degrees. With the setting of four sets of sampling tubes 32, two samplings can be performed, ensuring the accuracy of the detection.

[0046] In this embodiment, the discharge mechanism 12 includes a discharge pipe 34, a sliding sleeve 35, a partition 36, a second spring 37, a through hole 38, and a protrusion 39. The discharge pipe 34 is installed at the bottom of the sample container 7, and the bottom end of the discharge pipe 34 extends into the interior of the triangular weir groove 5. The sliding sleeve 35 is horizontally fixed on the discharge pipe 34, and the discharge pipe 34 and the sliding sleeve 35 are in communication. The partition 36 is horizontally slidably installed inside the sliding sleeve 35. The second spring 37 is provided between the end of the partition 36 and the inner end of the sliding sleeve 35. The partition 36 has a through hole 38 that cooperates with the discharge pipe 34. The bottom end of the shaft 21 is fixed with a protrusion 39, and the length direction of the protrusion 39 is perpendicular to the line connecting the two sets of sampling chambers 23.

[0047] Local working principle: After the water sample, sediment sample and mixed sample are collected, the turntable 22 rotates 360 degrees, and the protrusion 39 rotates to the initial position along with the shaft 21. The protrusion 39 squeezes the partition 36, making the through hole 38 and the discharge pipe 34 connected. The sample inside the sample bucket 7 will be injected into the triangular weir trough 5 through the discharge pipe 34 for discharge.

[0048] In this embodiment, the sediment content detection mechanism 11 includes a weighing cylinder 40, a drain pipe 41, a drain pipe 42, a solenoid valve 43, a filter cylinder 44, a filter screen 45, a pad 46, a first pressure sensor 47, a second pressure sensor 48, and a hot air blower 49. The weighing cylinder 40 is located on the side of the sample barrel 7. A drain pipe 41 is provided between the weighing cylinder 40 and the interior of the sample barrel 7. A drain pipe 42 is provided between the bottom of the weighing cylinder 40 and the interior of the triangular weir 5. Solenoid valves 43 are provided on both the drain pipe 41 and the drain pipe 42. A filter cylinder 44 is provided inside the drain pipe 41. A filter screen 45 is installed at the bottom of the filter cylinder 44. Pads 46 are symmetrically installed on the inner side of the weighing cylinder 40. A first pressure sensor 47 is provided between the top of the pad 46 and the upper bottom of the filter cylinder 44. A second pressure sensor 48 is provided at the inner bottom of the weighing cylinder 40. A hot air blower 49 is installed on the top of the weighing cylinder 40.

[0049] Local working principle: When detecting sediment content, the sample entering the sample container 7 enters the weighing cylinder 40 through the drainage tube 41. A certain amount of sample is extracted, and the weight of the sample is measured using the second pressure sensor 48. The sample is then discharged, while the sediment in the sample is blocked by the filter screen 45 and trapped at the top of the filter screen 45. The hot air blower 49 is then turned on to dry the sediment. The weight of the dried sediment is then used to obtain the weight of the sample and the weight of the sediment. The weight is calculated using a calculation formula. After the measurement is completed, the sediment on the filter screen 45 is extracted using a vacuum cleaner for secondary testing.
