[0002] Seagrass bed sediments contain a wealth of biological information, such as the species, abundance, and distribution of microorganisms (benthic animals, microorganisms, etc.). Sampling and analysis can help us understand the structure and function of these communities and, in turn, assess the health of the seagrass bed ecosystem. For example, a decrease or disappearance of certain sensitive species in the sediments could indicate that the ecosystem is being affected by pollution, overfishing, or other human disturbances.

[0003] However, when sampling and testing seagrass bed sediments, the samplers currently used are mostly fixed structures and lack flexibility and adjustability, which makes it difficult to completely sample the sediments in a columnar form when sampling seagrass bed sediments. This leads to the problem of missing detection of various sediment layers when studying the detection of seagrass bed sediments.

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0025] Example 1:

[0026] As attached Figure 1 To the attached Figure 6 As shown:

[0027] The present invention provides an adjustable seagrass bed sediment sampler, comprising: a sampler 1 for sampling seagrass bed sediment; a sampling mechanism, disposed on the sampler 1, for assisting the sampler 1 in adjusting sampling; a driving mechanism, slidably disposed in the sampler 1, for driving the sampling mechanism for adjusting sampling; a connecting mechanism, disposed inside the sampler 1, for connecting the sampling mechanism and the driving mechanism;

[0028] By providing a sampler 1 and rotatably connecting a plurality of arc-angle cones 3 at the bottom of the sampler 1, when the sampler 1 samples the seagrass bed sediment, the receiving block 9 can cooperate with the connecting shaft 5 and a plurality of guide shafts 10 to control the plurality of arc-angle cones 3 to unfold, so that the sampler 1 can cooperate with the plurality of arc-angle cones 3 to be vertically inserted into the seagrass bed sediment, and then the receiving block 9 cooperates with the connecting shaft 5 and a plurality of guide shafts 10 to control the plurality of arc-angle cones 3 to close and load the sampled seagrass bed sediment, and finally the limiting frame 7 is used to limit and fix it, so that the sampler 1 can be easily controlled and adjusted for sampling, thereby achieving the purpose of convenient and complete sampling of the seagrass bed sediment.

[0029] refer to Figure 1 and Figure 2 , the sampling mechanism includes a sampler 1, an arc cone 3 and a sealing door 2;

[0030] By providing a sampler 1, when sampling seagrass bed sediments, the sampler 1 can be inserted into the seagrass bed sediments to complete the columnar sampling work, and a plurality of rotating shafts 4 are rotatably connected to the bottom of the sampler 1, so that the sampler 1 can be rotatably connected to a plurality of arc-angle cones 3 through the plurality of rotating shafts 4, so that when the sampler 1 is inserted into the seagrass bed sediments for sampling, the plurality of arc-angle cones 3 can be rotated and unfolded through the plurality of rotating shafts 4, and kept in a vertical state with the side wall of the sampler 1, so that the sampler 1 is inserted into the seagrass bed sediments through the pointed cone structure at the bottom of the plurality of arc-angle cones 3, so as to complete the columnar sampling of the sediments, and then the plurality of arc-angle cones 3 are rotated and enclosed through the plurality of rotating shafts 4 to form a cone shape, so that the collected sediments are completely stored in the interior of the sampler 1 for complete sampling, detection and research use;

[0031] At the same time, a sealing door 2 is rotatably connected to the side wall of the sampler 1, so that after the sampling is completed, when it is necessary to detect and study the sampled sediment in the sampler 1, several arc-angle cones 3 can be rotated open through several rotating shafts 4 to take out the sampled sediment completely. The sealing door 2 can also be rotated open from the side wall of the sampler 1 to facilitate direct detection and research of the sampled sediment in the sampler 1, thereby improving the convenience of detection and research of sampled sediment.

[0032] Example 2:

[0033] refer to Figure 2 、 Figure 3 and Figure 5 , the driving mechanism includes a limiting slide 8, a connecting shaft 5 and a receiving block 9;

[0034] By opening a plurality of limiting sliding grooves 8 in the inner wall of the sampler 1, the sampler 1 can be conveniently connected to the receiving block 9 by limiting the sliding connection of the plurality of limiting sliding grooves 8, and the connecting shaft 5 is rotatably connected to the top of the receiving block 9, and the handle 6 is fixedly connected to the top of the connecting shaft 5, so that when the sampler 1 is in use, the staff can hold the sampler 1 in hand and hold the handle 6 with the other hand, and then push the handle 6 and the connecting shaft 5 to slide the receiving block 9 toward the inner bottom side of the sampler 1, so that the receiving block 9 can drive the plurality of arc angle cones 3 to rotate and open at the bottom of the sampler 1, so that the sampler 1 can be inserted into the seagrass bed sediment for sampling;

[0035] At the same time, a plurality of limit sliders 14 are fixedly connected to the side wall of the receiving block 9, and a plurality of limit sliders 14 are provided to be limitedly slidably connected to the plurality of limit slide grooves 8, so that when the handle 6 pushes the receiving block 9 to slide inside the sampler 1 through the connecting shaft 5, the receiving block 9 can be adjusted to maintain a stable vertical sliding direction through the plurality of limit slide grooves 8 and the limit sliders 14, so that the plurality of arc angle cones 3 can be opened or closed at the same time, so that the opening angles are the same, thereby facilitating the sampler 1 to be inserted into the seagrass bed sediment through the plurality of arc angle cones 3 for sampling;

[0036] Secondly, a bearing ring 13 is rotatably connected at the middle position of the top of the receiving block 9, so that the top of the receiving block 9 is conveniently rotatably connected to the connecting shaft 5 through the bearing ring 13, so that the connecting shaft 5 can be rotatably adjusted at the top of the receiving block 9, and a limiting frame 7 is fixedly connected to the side wall of the connecting shaft 5, and the limiting frame 7 is provided to be slidably connected to a plurality of limiting slots 8, so that when the connecting shaft 5 pushes the receiving block 9 to slide and adjust inside the sampler 1, the limiting frame 7 can be slidably connected to a plurality of limiting slots 8, thereby facilitating the improvement of the vertical sliding adjustment of the receiving block 9. Stability: when the connecting shaft 5 drives the receiving block 9 to slide upward, the several arc-angle cones 3 will be driven by the receiving block 9 to gradually close. When the limiting frame 7 is above the sampler 1, the several arc-angle cones 3 are just closed into a cone shape. At this time, the seagrass bed sediment has been sampled and stored inside the sampler 1. At the same time, the connecting shaft 5 is rotated so that the limiting frame 7 can rotate and offset from the corresponding positions of the several limiting slide grooves 8 and engage with the top of the sampler 1, so that the receiving block 9 is limited and cannot slide inside the sampler 1, thereby achieving a stable preservation state of the sediment inside the sampler 1;

[0037] In addition, a plurality of drainage holes 12 are provided on the top of the receiving block 9, so that when the sampler 1 is inserted into the seagrass bed sediment through a plurality of arc-angle cones 3, the seawater in the sampler 1 will overflow from the plurality of drainage holes 12, thereby facilitating the filling of the space inside the sampler 1 with the seagrass bed sediment and preventing the seawater from clogging the sediment.

[0038] Example 3:

[0039] refer to Figure 3 、 Figure 4 and Figure 6 , the connecting mechanism includes a guide shaft 10, a control groove 11, a spring 15 and a control slider 16;

[0040] By opening a control groove 11 on the inner wall of the arc angle cone 3 and fixing a spring 15 in the inner wall of the control groove 11, the arc angle cone 3 is conveniently connected to the control slider 16 by elastic limiting sliding through the control groove 11 and the spring 15, and a receiving shaft 17 is rotatably connected to the control slider 16, so that the control slider 16 can be rotatably connected to the guide shaft 10 through the receiving shaft 17, and then the top of the guide shaft 10 is fixedly connected to the bottom of the receiving block 9, so that when the receiving block 9 slides up and down inside the sampler 1, the arc angle cone 3 can be driven by the guide shaft 10, the receiving shaft 17 and the control slider 16 to rotate, expand and close for adjustment;

[0041] At the same time, when the receiving block 9 controls the use of the plurality of arc angle cones 3, when the receiving block 9 is slid and adjusted toward the inner bottom side of the sampler 1, the receiving block 9 will push the plurality of guide shafts 10 to slide toward the bottom side of the sampler 1, and then the plurality of guide shafts 10 cooperate with the receiving shaft 17 to adjust the angle, pushing the plurality of control slide blocks 16 to slide toward the bottom side of the sampler 1. Since the guide shaft 10 always remains in a vertical state, when the guide shaft 10 drives the control slide block 16 to slide downward, the plurality of guide shafts 10 and the control slide block 16 will push the plurality of arc angle cones 3 into an expanded state, thereby facilitating the sampler 1 to sample seagrass bed sediments through the expanded plurality of arc angle cones 3.

[0042] Secondly, when the receiving block 9 slides upward to regulate the use of several arc-angle cones 3, when the receiving block 9 slides upward inside the sampler 1, it will drive several control sliders 16 to slide upward in the control groove 11 through several guide shafts 10. Since the inner wall of the arc-angle cone 3 is in an inclined state, the control slider 16 will drive the several arc-angle cones 3 to rotate to a closed state when sliding upward, and the control slider 16 is elastically supported by the spring 15 in the control groove 11. Therefore, when no downward force is applied to the receiving block 9, the control slider 16 will automatically slide toward the top side of the sampler 1 under the elastic capacity of the spring 15, so that before the sampler 1 is used, several arc-angle cones 3 are in a closed state, which is easier to carry and use.

[0043] Working principle: By providing a sampler 1, when sampling seagrass bed sediments, the sampler 1 can be inserted into the seagrass bed sediments to complete the columnar sampling work, and a plurality of rotating shafts 4 are rotatably connected at the bottom of the sampler 1, so that the sampler 1 can be rotatably connected to a plurality of arc angle cones 3 through the plurality of rotating shafts 4, so that when the sampler 1 is inserted into the seagrass bed sediments for sampling, the plurality of arc angle cones 3 can be rotated and unfolded through the plurality of rotating shafts 4, and kept vertically with the side wall of the sampler 1, so that the sampler 1 is inserted into the seagrass bed sediments through the pointed cone structure at the bottom of the plurality of arc angle cones 3, so as to complete the columnar sampling of the sediments, and then the plurality of arc angle cones 3 are rotated and enclosed through the plurality of rotating shafts 4 to form a cone shape, so that the collected sediments are completely preserved in the interior of the sampler 1 for complete sampling, detection and research use, and at the same time, a bearing ring 13 is rotatably connected at the middle position of the top of the receiving block 9, so that the top of the receiving block 9 is convenient to be connected to the connecting shaft through the bearing ring 13 5 is rotatably connected, so that the connecting shaft 5 can be rotated and adjusted at the top of the receiving block 9, and a limiting frame 7 is fixedly connected to the side wall of the connecting shaft 5, and the limiting frame 7 is set to be slidably connected to a plurality of limiting slide grooves 8, so that when the connecting shaft 5 pushes the receiving block 9 to slide and adjust inside the sampler 1, the limiting frame 7 can be slidably connected to the plurality of limiting slide grooves 8, so as to improve the stability of the vertical sliding adjustment of the receiving block 9. When the connecting shaft 5 drives the receiving block 9 to slide upward, the plurality of arc angle cones 3 will be driven by the receiving block 9 to gradually close. When the limiting frame 7 is above the sampler 1, the plurality of arc angle cones 3 are just closed into a cone shape. At this time, the seagrass bed sediment has been sampled and stored in the interior of the sampler 1. At the same time, the connecting shaft 5 is rotated, so that the limiting frame 7 can be rotated and offset from the corresponding positions of the plurality of limiting slide grooves 8 and engaged with the top of the sampler 1, so that the receiving block 9 is limited and cannot slide inside the sampler 1, thereby achieving a stable preservation state of the sediment inside the sampler 1.
