Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to a device for collecting multiple water samples at the same point for environmental detection. Background Art

[0002] The same-point multi-collection water sampling device for environmental testing is a tool specially used to obtain water samples at different depths at the same sampling point. It aims to solve the problems of water sample mixing, large errors, and low efficiency in traditional sampling methods. Environmental monitoring requires water samples to be representative in time and space. Multiple collection at the same point can reduce the deviation caused by spatial differences in sampling points through multi-point sampling at the same location. It is especially suitable for scenes with obvious vertical pollution gradients. Water bodies may exhibit different physical, chemical or biological properties at different depths. Surface water is easily affected by external pollution, while deep water may accumulate sediment or anaerobic substances. At this stage, when sampling at different water levels at the same point, a large amount of dead branches and leaves will be deposited in the deep water part of the river channel. There will be a large number of microorganisms in the dead branches and leaves. The microorganisms will decompose the substances to be tested (such as nitrates into nitrites), which will lead to deviations in the results. Summary of the Invention

[0009] When the equipment needs to be adjusted to the appropriate depth, the stepper motor is started, and the stepper motor drives the threaded column to rotate. When the threaded column rotates, it drives the threaded block connected to the thread to move. When the threaded block moves, it drives the placement table to move. When the placement table moves, it drives the support arm to move. When the support arm moves, it drives the linkage block to move through the limit column. When the linkage block moves, it drives the stretching column to move. When the placement table moves, it pushes the groove disk toward the bottom of the support rod through the load-bearing rod. The movement of the groove disk drives the limit ring to move to the specified position.

Two push blocks are fixedly connected to each translation column, and each push block is V-shaped. Each push block is provided with two U-shaped grooves for facilitating the transfer of branches.

[0011] When the groove plate moves, the groove plate drives the blocking column to move and the connecting pipe to move, and the movement of the connecting pipe drives the spring to be compressed, and the connecting pipe pushes the push rod to move toward a position away from the frame plate through the linkage column when moving, and the push rod drives the translation column to move when moving, and the translation column drives the push block to move toward a position away from the frame plate when moving, and then the push block pushes away the dead branches in the deep water of the river when moving, and when the placing platform moves toward the top of the transmission column, the compressed spring rebounds and drives the connecting pipe to reset, and the reset of the connecting pipe drives the groove plate to always fit with the load-bearing rod.

[0012] As a preferred technical solution of the present invention, a blocking assembly for collection is provided at the top of the gripping rod, and a support frame is provided inside the blocking assembly. The support frame is U-shaped, and the bottom of the support frame is fixedly connected to the gripping rod. The top of the support frame is fixedly connected to a bearing plate, and a movable column is movably connected to the bearing plate. The movable column passes through the gripping rod and is fixedly connected to the bearing ring. A ratchet is fixedly connected to the outside of the movable column. A starting rod is provided at the top of the ratchet, and the starting rod is fixedly connected to the movable column.

The bottom of the bearing plate is fixedly connected to a placing column, and a blocking tooth is fixedly connected to the outside of the placing column, and the blocking tooth is engaged with the ratchet.

[0013] When it is necessary to collect the deep water level at the same point in the river, the starting rod is rotated, and the starting rod drives the pushing tooth to rotate when it is rotated, and the pushing tooth drives the ratchet to rotate when it is rotated, and the ratchet drives the movable column to rotate when it is rotated, and the bearing ring rotates when the movable column rotates, and the bearing ring drives the transmission column to rotate when it rotates, and the transmission column drives the groove disk to rotate through the blocking column when it rotates. When the groove disk rotates, the bearing rod and the connecting pipe will not rotate when the groove disk rotates because the annular groove and the movable groove are provided on the groove disk. When the flow force of the river water pushes the transmission column to reset to its original direction, the ratchet prevents the ratchet from rotating in the opposite direction through the engaged blocking teeth.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a suction component, a deep sampling component and a sedimentation component in combination. When it is necessary to sample multiple water bodies at the same point, the first sealing cylinder, the second sealing block and the filter disc can be used to filter the water at the deep water level, thereby preventing the microorganisms in the dead branches and leaves in the deep water part of the river from decomposing the test substances, thereby improving the structural accuracy of water quality monitoring in the deep water part.

[0015] 2. The present invention is equipped with a suction component, a deep sampling component, a sedimentation component and a debris avoidance component. When sampling multiple water bodies at the same point is required, the threaded rod is used to make the threaded block drive the placement table and the deep sampling component to move vertically to the specified depth. At the same time, the push block automatically pushes away obstacles such as dead branches, thereby clearing obstacles in advance for deep water sampling.

[0016] 3. The present invention uses the suction component and the deep sampling component in combination. When it is necessary to sample multiple water bodies at the same point, the lifting rod and the lifting rod are linked to use the negative pressure in the first sealing cylinder and the second sealing cylinder to extract water. The sealing block moves to form a one-way water flow. The layered sealing design completely isolates shallow and deep water samples, avoiding detection errors caused by multi-layer mixing in traditional sampling.

[0017] 4. The present invention uses a suction component, a deep sampling component and a sedimentation component in combination. When sampling is required at the same point for multiple water bodies, the stepper motor drives the threaded column, which drives the placement table and the deep sampling component to move vertically through the threaded block. This can achieve precise control of the deep sampling position according to the water level requirements of the river channel. Mechanized sedimentation replaces manual adjustment, and the depth positioning error is controllable, adapting to different riverbed terrains.

[0018] 5. Through the setting of the blocking component, when it is necessary to sample multiple water bodies at the same point, the ratchet and the blocking teeth are engaged to prevent the reverse rotation of the transmission column caused by the impact of the water flow, ensuring that the water sample will not flow back and overflow after sampling, thereby improving the sampling reliability and avoiding water sample loss or secondary contamination.

[0019] 6. The present invention is equipped with a debris avoidance component. When sampling is required at the same point for multiple water bodies, the Z-shaped connecting tube cooperates with the spring return mechanism to push away obstacles such as dead branches through the V-shaped push block. The U-shaped groove on the push block can clamp the dead branches to prevent them from rebounding, thus protecting the normal operation of the sealing tube and reducing the interference of river debris on sampling.

[0028] Working principle: The first step, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, when it is necessary to collect shallow water levels at different water levels at the same point in the river, the gripping rod 1 is placed at the position in the river that needs to be cleaned, and then the pressing plate 45 is rotated.

When the linkage block 18 moves, it drives the stretching column 25 to move. When the placement table 4 moves, it pushes the groove plate 19 toward the bottom of the support rod 2 through the carrying rod 21. The movement of the groove plate 19 drives the limiting ring 48 to move to the specified position. The third step, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, when the groove plate 19 moves, the groove plate 19 drives the blocking column 20 to move and drives the connecting pipe 30 to move, and then the movement of the connecting pipe 30 drives the spring 33 to be compressed, and the connecting pipe 30 pushes the push rod 32 to move toward a position away from the frame plate 31 through the linkage column 34 when moving, and the push rod 32 drives the translation column 36 to move when moving, and the translation column 36 drives the push block 35 to move toward a position away from the frame plate 31 when moving, and then the push block 35 pushes away the dead branches in the deep water of the river when moving, and when the placing platform 4 moves toward the top of the transmission column 3, the compressed spring 33 rebounds and drives the connecting pipe 30 to return to its original position, and the return of the connecting pipe 30 drives the groove plate 19 to always fit with the load-bearing rod 21; The fourth step is as follows Figure 11 and Figure 12 As shown, when it is necessary to collect the deep water level at the same point in the river channel, the starting rod 41 is rotated, and the starting rod 41 drives the pushing tooth 44 to rotate when it rotates, and the pushing tooth 44 drives the ratchet 40 to rotate when it rotates, and the ratchet 40 drives the movable column 39 to rotate when it rotates. When the movable column 39 rotates, the bearing ring 6 rotates, and when the bearing ring 6 rotates, it drives the transmission column 3 to rotate. When the transmission column 3 rotates, it drives the groove disk 19 to rotate through the blocking column 20. When the groove disk 19 rotates, because the groove disk 19 is provided with an annular groove and a movable groove, the bearing rod 21 and the connecting pipe 30 will not rotate when the groove disk 19 rotates. When the flow force of the river water pushes the transmission column 3 to return to its original direction, the ratchet 40 prevents the ratchet 40 from rotating in the opposite direction by the meshing blocking teeth 42. Step 5: Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, when it is necessary to collect the deep water level at the same point of the river channel, the groove disk 19 is rotated. When the groove disk 19 rotates, the trigger rod 22 is driven to rotate. When the trigger rod 22 is driven to rotate, the trigger column 23 is driven to rotate. When the trigger column 23 rotates, the limiting ring 48 is driven to move. When the limiting ring 48 is driven, the stretching column 25 is driven to move in the direction away from the second sealing cylinder 24. When the second sealing cylinder 24 moves, the second sealing block 26 is driven to move. When the second sealing block 26 moves, negative pressure is generated when it moves. When the second sealing block 26 moves, the collected water filtered by the filter disk 46 is sucked into the inside of the second sealing cylinder 24 along the collection hole of the second sealing cylinder 24.
