Description

Technical Field

[0001] The present invention relates to the technical field of sample sampling, and in particular to a sample collection device and a collection method for a blue carbon ecological point. Background Art

[0002] Blue carbon systems, that is, carbon storage in marine and coastal ecosystems, mainly include ecosystems such as salt marshes, mangroves and seagrass beds. These ecosystems play an important role in mitigating climate change, protecting biodiversity and providing human services. For the detection of blue carbon systems, soil stability can be assessed by sampling the soil, but it is not limited to seabed soil, but can also include the following types of soil, such as intertidal soil, coastal wetland soil, river estuary soil, etc.

[0003] In the prior art, using a cylindrical sampling tube to sample the soil will leave holes, and the holes after sampling need to be filled because the unfilled holes will increase the scouring force of water on the soil during high tide, thereby causing erosion and soil loss of the surrounding soil. In addition, in the intertidal ecosystem, the survival of many small organisms and invertebrates depends on the integrity of the soil in the area. The holes left after sampling may become traps for these organisms, especially at high tide, when they may fall into the holes and be unable to climb out by themselves, affecting biodiversity.

DETAILED DESCRIPTION

[0035] See also Figure 1-Figure 10 In an embodiment of the present invention, a sample collection device for a blue carbon ecological point includes a box body 1, a lifting rod 2 is movably arranged in the box body 1, a sampling barrel 3 is fixedly arranged at the end of the lifting rod 2, a groove 101 is opened at the bottom of the box body 1, and the sampling barrel 3 is slidably connected with the groove 101, a base 4 is fixedly arranged below the box body 1, a barrel 5 is arranged in the base 4, the top of the barrel 5 is fixedly connected to the bottom of the box body 1, and a filling component 6 for filling the sampling hole is arranged below the barrel 5; some soil with similar properties to the sampling soil is collected in advance near the collection point, such as the surface soil of the nearby soil, and the collected soil is loaded into The base 4 and the box body 1 are placed in the material barrel 5, and then the base 4 and the box body 1 are placed in the area to be sampled, and the lifting rod 2 is moved downward. The lifting rod 2 moves downward to drive the sampling barrel 3 to pass through the groove 101 downward so that the sampling barrel 3 contacts the soil. The bottom of the sampling barrel 3 is provided with multiple pointed heads, and the inner side of the bottom is recessed inwardly and provided with multiple plates in a circular array. The plates are made of elastic material. The pointed heads can facilitate the sampling barrel 3 to break the soil and enter the soil. The plates can prevent the soil from flowing out of the sampling barrel 3 when the sampling barrel 3 is lifted up after the sampling is completed. After the sampling is completed, there will be a cylindrical hole in the soil, and the soil in the material barrel 5 can be transported to the hole through the filling component 6 to fill the hole.

When the sampling is completed, the transverse plate 61 is moved along the fixed plate 62 in the direction close to the groove 101, and the movement of the transverse plate 61 will drive the measuring cylinder 63 to move. The cylinder 63 and the cover plate 64 move along the positioning plate 65 until the measuring cylinder 63 moves to the end of the positioning plate 65, and the measuring cylinder 63 continues to move so that the cover plate 64 gradually loses the contact with the positioning plate 65.

During the movement, the cross plate 61 will block the bottom of the barrel 5 so that the soil in the barrel 5 will not flow down. After the filling is completed, the cross plate 61 is moved in the opposite direction. The cross plate 61 will drive the measuring cylinder 63 and the cover plate 64 in the expanded state to move in the opposite direction, and the cover plate 64 will abut against the positioning plate 65 to flip the cover plate 64 to the closed state until the cross plate 61 drives the measuring cylinder 63 to move below the barrel 5, and the soil in the barrel 5 will refill the measuring cylinder 63, which is convenient for filling the subsequent sampling holes.

In the initial state, the measuring cylinder 63 is filled with soil and the cover 64 is in a closed state, and the first part of the gear of the incomplete gear 14 is in abutment with the first gear 13. At this time, the rotating rod 34 is rotated counterclockwise, and the rotation of the rotating rod 34 drives the incomplete gear 14 to rotate, and the rotation of the incomplete gear 14 makes the first part of the gear mesh with the first gear 13, thereby driving the first gear 13 to rotate clockwise, and the rotation of the first gear 13 drives the round rod 12 to rotate so that the measuring cylinder 63 moves toward the concave The gear 14 is moved in the direction of the groove 101 until the cover 64 is opened to release the soil in the measuring cylinder 63 to fill the hole. In the process of moving from the measuring cylinder 63 to the opening of the cover 64, the first part of the gear of the incomplete gear 14 is meshed with the first gear 13. After the cover 64 is opened, the incomplete gear 14 continues to rotate. At this time, the part without a gear between the two parts of the gear will not drive the first gear 13 to rotate, so the measuring cylinder 63 remains stationary, which allows more time for the soil in the measuring cylinder 63 to fall into the hole below. After a period of time, the second part of the gear of the incomplete gear 14 is meshed with the first gear 13 again, and it will also drive the round rod 12 to rotate clockwise so that the measuring cylinder 63 moves in the opposite direction until it moves to the initial position. In this step, the design of the incomplete gear 14 can ensure that the soil in the measuring cylinder 63 is automatically transported to the hole and the measuring cylinder 63 can be allowed to stay for a period of time to ensure that all the soil flows out of the measuring cylinder 63.

Some of the soil will fall around the hole. At this time, the push rod 21 can be moved, and the movement of the push rod 21 will drive the moving rod 18 to move, so that the limit frame 16 moves. The movement of the limit frame 16 will drive the limit plate 19 to rotate, and will also drive the positioning rod 20 to rotate, thereby driving the two push plates 17 to move towards each other. The push plates 17 approach each other and push the soil around the hole into the hole, so that the hole can be filled better and intact. Similarly, the reverse movement of the push rod 21 will drive the push plates 17 to move away from each other.

The pull rod 24 will drive the movable plate 23 to move so that the two movable plates 22 move towards each other. During this process, the spring 27 will be compressed.

[0048] The working principle of the present invention is: collect some soil with similar properties to the sampled soil near the collection point in advance, such as the surface soil of the nearby soil, put the collected soil into the barrel 5, then place the base 4 and the box 1 in the area to be sampled, move the lifting rod 2 downward, the lifting rod 2 moves downward to drive the sampling barrel 3 through the groove 101 downward so that the sampling barrel 3 contacts the soil for sampling. After the sampling is completed, there will be a cylindrical hole on the soil, the rotation of the rotating shaft 29 will drive the rotating wheel 32 to rotate, thereby driving another rotating wheel 32 to rotate through the belt 33 and then driving the rotating rod 34 to rotate, the rotation of the rotating rod 34 will drive the incomplete gear 14 to rotate, and gears are set at two symmetrical positions on the outside of the incomplete gear 14. In the initial state, the measuring cylinder 63 is filled with soil and the cover 64 is in a closed state. The first part of the gear of the incomplete gear 14 is in contact with the first gear 13. At this time, the incomplete gear 14 is rotated counterclockwise. The rotation of the incomplete gear 14 makes the first part of the gear mesh with the first gear 13, thereby driving the first gear 13 to rotate clockwise. The rotation of the first gear 13 drives the round rod 12 to rotate so that the measuring cylinder 63 moves toward the groove 101 until the cover 64 is opened to release the soil in the measuring cylinder 63 to fill the hole. In the process of moving from the measuring cylinder 63 to the opening of the cover 64, the first part of the gear of the incomplete gear 14 is meshed with the first gear 13. After the cover 64 is opened, the incomplete gear 14 continues to rotate. At this time, the part without a gear between the two parts of the gear is not It will drive the first gear 13 to rotate, so the measuring cylinder 63 remains stationary, so that there is more time for the soil in the measuring cylinder 63 to fall into the hole below. After a period of time, the second part of the gear of the incomplete gear 14 will mesh with the first gear 13 again, and it will also drive the round rod 12 to rotate clockwise so that the measuring cylinder 63 moves in the opposite direction until it moves to the initial position. At the same time, the rotation of the rotating shaft 29 drives the curved slide 291 to rotate. Since the limiting rod 30 is fitted in the curved slide 291, the rotation of the rotating shaft 29 drives the limiting rod 30 and the sleeve 31 to reciprocate along the vertical plate 28. The reciprocating movement of the sleeve 31 will drive the reciprocating movement of the push rod 21, and the movement of the push rod 21 will drive the moving rod 18 to move, so that the limit frame 1 6 moves, the movement of the limit frame 16 will drive the limit plate 19 to rotate, and will also drive the positioning rod 20 to rotate, thereby driving the two push plates 17 to move in the direction of approaching each other. The push plates 17 approaching each other will push the soil around the hole into the hole, so that the hole can be filled better and intact. Similarly, the reverse movement of the push rod 21 will drive the push plates 17 to move away from each other. In the process of the push plates 17 approaching each other, the pull rod 24 and the vertical plate 25 will be driven to move along the horizontal groove 172 until the vertical plate 25 abuts against the baffle 26. Continuously moving the push plate 17 will cause the vertical plate 25 and the pull rod 24 to move in the opposite direction of the moving direction. The pull rod 24 will drive the movable plate 23 to move, thereby causing the two movable plates 22 to move in the direction of approaching each other. In this process, the spring 27 will be compressed. Similarly,When the movable plate 22 and the push plate 17 have completed pushing the soil, the push rod 21 moves in the direction to drive the push plate 17 away from each other, and under the action of the spring 27, the movable plate 22 moves away from each other until it returns to the initial position.
