Description

Technical Field

[0001] The invention relates to the technical field of slope sampling, and in particular to a slope environment sampling device used for soil and water conservation. Background Art

[0002] The river slope environment refers to the slope areas on both sides of the river. These areas are affected by factors such as river flow, floods, soil, hydrology and climate. Due to the flow of the river and the terrain characteristics of the surrounding environment, the river slope environment often has the characteristics of dynamic change. The river slope is not only an important part of the ecosystem, but also involves soil and water conservation, flood control and disaster relief. In order to ensure soil and water conservation on the river slope, sampling is required at the river slope.

[0003] The current slope environmental sampling equipment has certain limitations in the sampling process. First, water quality and silt samples need to be collected separately and cannot be carried out at the same time, resulting in low overall sampling efficiency and increased operation time and workload. In addition, when performing fixed-depth water quality sampling, the equipment lacks a prompt function when reaching the specified sampling depth. This makes it difficult for samplers to accurately judge the sampling depth in actual operation, which in turn causes large differences in the water quality depth inside the sampling bucket. This difference will lead to uneven quality of the collected water samples, affecting the accuracy and reliability of the sampling results. Therefore, the existing equipment urgently needs to be improved in improving sampling efficiency and sampling accuracy, especially in the functions of water quality sampling depth control and simultaneous sample collection. Therefore, it is urgent to design a slope environmental sampling equipment for soil and water conservation. Summary of the invention

[0024] Please see attached Figure 1 and attached Figure 7 In a preferred embodiment, a liquid inlet pipe 3 and a liquid outlet pipe 4 are symmetrically connected and installed at the end of the surface of the sampling barrel 1, a one-way valve is installed on the liquid inlet pipe 3, and a valve is installed on the liquid outlet pipe 4, and a V-shaped frame 5 for convenient pulling is installed on the top of the surface of the sampling barrel 1; As mentioned above, when sampling is completed, the water inside the sampling bucket 1 can be released and collected by opening the valve. When the sludge needs to be collected, the sludge roller 39 is driven to rotate by rotating the turntable (when the bottom plate 23 does not contact the ground, the convex teeth 27 and the gear 28 do not contact), and the sludge inside the sludge roller 39 can be discharged and collected.

[0025] The working principle of the present invention is as follows: when it is necessary to sample muddy water on the river slope, first open the valve on the liquid inlet pipe 3, and as the piston rod 6 is pushed downward, the sealing disk 33 is driven to move downward and the straight spring 35 generates a pulling force until the sealing disk 33 contacts the bottom of the sampling barrel 1. Due to the setting of the slider 14 and the first spring rod 15, the elastic force generated by the first spring rod 15 causes the slider 14 to drive the slope block 16 to insert into the slot 17 to limit and lock the piston rod 6. At this time, the gas below the sealing disk 33 in the sampling barrel 1 will be discharged through the valve, while the gas above the sealing disk 33 in the sampling barrel 1 is in The valve is then closed, and the indicating block 21 and the indicating plate 22 are lifted up by the two U-shaped handles to generate a pulling force on the second spring rod 20, so that the two cylindrical grooves 38 have gas inside. Then the second spring rod 20 resets the indicating block 21 and the indicating plate 22, and at this time the cylindrical groove 38 is located inside the frame 18. Finally, the knob 40 is turned to drive the lead screw 11 to rotate, and the lead screw 11 rotates to drive the movable block 10 to move, and the movable block 10 moves to drive the U-shaped column 12 to move, so that the horizontal distance of the connecting rope 8 can be adjusted, and the water quality at different depths can be sampled; Then place the sampling barrel 1 on the river bank. First, the gas inside the mud roller 39 will be discharged through the through hole on the mud roller 39, and the buoy 7 will float on the liquid surface. When the sampling barrel 1 and the sampling plate 2 are all in the liquid surface, as the sampling barrel 1 and the sampling plate 2 continue to move downward, the connecting rope 8 will gradually tighten. When the connecting rope 8 is tightened and the sampling barrel 1 and the sampling plate 2 move downward again, the tightened connecting rope 8 will drive the slider 14 to move, and the movement of the slider 14 will drive the indicator block 2 1 and the ramp block 16 move, the slider 14 will contact the indicator block 21 when it starts to move and drive the indicator block 21 to move upward. At this time, the ramp block 16 is not separated from the card slot 17. As the indicator block 21 moves, the cylindrical groove 38 on the indicator block 21 will separate from the frame 18, and the gas in the cylindrical groove 38 will be released into the liquid in the form of bubbles and float upward. When the staff observes the bubbles, they stop moving the sampling barrel 1 and the sampling tray 2. As the ramp block 16 moves, the cylindrical groove 38 on the indicator block 21 will separate from the frame 18. The slope block 16 will separate from the card slot 17 to complete the unlocking of the piston rod 6. The negative pressure inside the sampling barrel 1 and the tension generated by the straight spring 35 will cause the sealing disk 33 to move upward, and the one-way valve on the liquid inlet pipe 3 will open. The water quality inside the river will enter the sampling barrel 1 through the liquid inlet pipe 3. In summary, it has been achieved that the sampling barrel 1 stops moving after reaching the specified depth, ensuring that the water quality at the specified depth can be sampled during water quality sampling, thereby improving the sampling accuracy and uniformity of water quality samples. As the sampled water quality inside the sampling barrel 1 increases, the floating plate 37 will drive the T-bar 34 to float upward until the sampling inside the sampling barrel 1 is completed. The T-bar 34 will contact the indicator plate 22 and push the indicator plate 22 to move upward. In summary, the gas inside the cylindrical groove 38 on the indicator plate 22 will also be emitted into the liquid in the form of bubbles and float upward. When the staff sees the bubbles again, it indicates that the water quality sampling is completed and the sampling barrel 1 and the sampling plate 2 can continue to be moved downward to sample the sludge. As the sampling disc 2 moves downward, the bottom contact plate 23 will contact the silt at the bottom of the slope and stop moving, then the slide plate 24 and the convex tooth 27 will stop moving, and the sampling disc 2 will drive the gear 28 and other components to continue moving downward. It should be noted that the convex tooth 27 and the gear 28 are not in contact at the beginning. Due to the arrangement of the slide plate 24 and the convex tooth 27, when the gear 28 moves downward and contacts the convex tooth 27, the gear 28 will rotate, and the rotation of the gear 28 drives the torsion spring 31 to generate torque. At this time, the rotation of the gear 28 will not drive the rotating shaft 30 to rotate through the one-way bearing 29. After the gear 28 rotates one circle, the convex tooth 27 and the gear 28 are separated, indicating that the sampling disc 2 has moved to the maximum limit. As the torque generated by the torsion spring 31 is quickly released, the gear 28 rotates one circle in the opposite direction. The rotation in the opposite direction will drive the rotating shaft 30 to rotate one circle through the one-way bearing 29, and the rotation of the rotating shaft 30 will drive the mud sampling roller 39 to rotate one circle, so that the silt at the bottom of the slope is shoveled into the inside of the mud sampling roller 39, and due to the effect of gravity, the mud sampling roller 39 after mud sampling can always be in a state where the feed trough is facing upwards. In summary, the sampling of the silt at the bottom of the slope can be completed. When the mud sampling is completed, the sampling bucket 1 and the sampling plate 2 are lifted up. Since the convex tooth 27 is hinged to the slide plate 24 through the one-way elastic hinge, the gear 28 moves upward relative to the convex tooth 27. The convex tooth 27 will rotate relative to the slide plate 24, and the gear 28 will not rotate at this time, further avoiding the rotation of the mud sampling roller 39 after mud sampling. Finally, the sampling bucket 1 and the sampling plate 2 can be lifted up to leave the liquid surface to complete the sampling. In summary, the water quality and silt at the slope can be sampled at the same time, avoiding the situation where water quality and silt samples need to be collected separately and cannot be collected at the same time, resulting in low overall sampling efficiency. It can also indicate when the water quality sampling reaches the specified depth, ensuring the uniformity, accuracy and uniformity of the water quality sampling depth, thereby improving the sampling effect of the equipment on the slope environment.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
