Technical Field
[0001] This utility model belongs to the field of shallow water sampling technology, specifically a shallow water sediment sampling device. Background Technology
[0002] Shallow water areas play a crucial role in the overall aquatic ecosystem, and their sediments contain a wealth of information, such as the history of water pollution, the distribution of benthic organisms, and the deposition and cycling of nutrients. Sampling and analyzing sediments from shallow water areas can help researchers and environmental monitoring departments gain a deeper understanding of the aquatic ecological environment, assess the degree of water pollution, and formulate corresponding remediation and protection measures.
[0003] However, most existing methods of collecting bottom sediment involve manual sampling using tools such as shovels and grabs, which results in extremely low sampling efficiency. Furthermore, the inability to sample at a fixed depth leads to low sampling accuracy and poor sampling results. To address these issues, this invention designs a shallow water bottom sediment sampling device. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a shallow water sediment sampling device, which effectively solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a shallow water sediment sampling device, comprising a sampling tube, a connecting tube at the left end of the sampling tube, a connecting block fixed at the left end of both the sampling tube and the connecting tube, a plurality of assembly rods inside the connecting block, a sampling rod inside both the sampling tube and the connecting tube, a handle fixed to the left side of the sampling rod at the left end, a positioning tube on the left side of the connecting tube, two connecting plates fixed to the left end of the positioning tube, a measuring disc at the right end of each connecting plate, a measuring ruler wound inside each measuring disc, a distance measuring plate at the right end of each measuring ruler, two distance measuring plates fixedly connected by a connecting ring, a sampling ring at the right end of the sampling rod on the right side, a plurality of sampling plates fixed outside the sampling ring, a plurality of sampling baffles fixed inside the sampling tube, each sampling plate being able to fit tightly against the sampling baffle at one end, a positioning plate fixed to the left end of each distance measuring plate, and a locking rod slidably connected inside each positioning plate.

The left end of the spring is fixedly connected to the connecting block at the right end of the sampling tube.
[0007] Preferably, the sampling tube, the connecting tube, and the positioning tube are internally fixed with positioning bearings via bearing connecting plates. The inner ring of each positioning bearing is fixedly connected to the sampling rod inside it. A sampling rod bottom connecting block is provided at the connection point of every two sampling rods. Each sampling rod bottom connecting block is fixedly connected to the sampling rod at its left end. A sampling tube top connecting block is slidably connected to the right end of each sampling rod bottom connecting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

This causes the sampling plate and the sampling baffle to fit tightly together, thereby achieving sampling and ensuring sampling accuracy while improving sampling efficiency. Furthermore, the contrast between several sampling baffles further ensures sampling efficiency.
[0012] This invention allows for the alteration of the overall length of the device through the assembly of connecting tubes, thereby enabling the sampling of samples at different depths and expanding the overall applicability of the device. Simultaneously, the device's assembly spring is highly elastic, driving the assembly rod to move within the assembly hole. This locks the sampling tube, connecting tube, and positioning tube, ensuring stability and accuracy during sampling.

[0029] When using this device, the operator inserts the positioning tube 7, the connecting tube 4, and the sampling tube 1. At this time, the assembly rod 5 and the assembly spring 501 fix the positioning tube 7, the connecting tube 4, and the sampling tube 1 together. The operator then moves the entire device to the shallow water area where sampling is required. The operator inserts the entire device into the mud bottom. The sampling head 101 facilitates insertion into the mud bottom. The measuring plate 2 is in close contact with the bottom. The mud outlet 102 ensures that the measuring plate 2 is also in close contact with the mud bottom. Simultaneously, the measuring shaft 305 and the measuring spring 304 keep the measuring ruler 3 taut, thus ensuring measurement accuracy. When the operator monitors the insertion of the sampling tube 1 using the measuring ruler 3... After reaching the required depth in the mud, the operator rotates the handle 6, which in turn rotates the sampling rod 601, causing the bottom connecting block 604 of the sampling rod to rotate, which in turn rotates the top connecting block 605 of the sampling tube, thus rotating all the sampling rods 601. This, in turn, rotates the sampling ring 8, causing the sampling plate 801 to rotate into the sampling baffle 802, thereby conveying the sample into the sampling baffle 802. This seals the sampling plate 801 and the sampling baffle 802, preventing the sample from falling out of the sampling baffle 802 and ensuring the sampling effect. At this point, the operator removes the entire device and then reverses the handle 6, causing the sampling plate 801 to detach from the sampling baffle 802, allowing the sample to fall out, thus completing the sampling process.
[0030] The working process of this utility model is as follows: When using this device, the operator inserts the positioning tube 7, the connecting tube 4, and the sampling tube 1. At this time, due to the action of the assembly rod 5 and the assembly spring 501, the positioning tube 7, the connecting tube 4, and the sampling tube 1 are fixed together. The operator then moves the entire device to the shallow water area where sampling is required. The operator inserts the entire device into the mud bottom. Due to the action of the sampling head 101, the entire device can be easily inserted into the mud bottom. At this time, the measuring plate 2 is in close contact with the bottom of the water. Due to the action of the mud outlet 102, the measuring plate 2 is also in close contact with the mud bottom. Simultaneously, due to the action of the measuring shaft 305 and the measuring spring 304, the measuring ruler 3 is kept taut, thereby ensuring the accuracy of the measurement. When the operator monitors the measurement from the dimensions of the measuring ruler 3... After the sampling tube 1 is inserted to the required depth into the mud, the operator rotates the handle 6, which in turn rotates the sampling rod 601, thereby rotating the bottom connecting block 604 of the sampling rod, which in turn rotates the top connecting block 605 of the sampling tube, which in turn rotates all the sampling rods 601, thereby rotating the sampling ring 8, which in turn rotates the sampling plate 801 into the sampling baffle 802, thus conveying the sample into the sampling baffle 802, thereby sealing the sampling plate 801 and the sampling baffle 802, preventing the sample from falling out of the sampling baffle 802, and thus ensuring the sampling effect. At this time, the operator removes the entire device, and then reverses the handle 6, so that the sampling plate 801 is detached from the sampling baffle 802, so that the sample falls out, thus completing the sampling work.
