Description

Technical Field

[0001] The invention relates to the technical field of slope sampling, and in particular to a slope environment sampling device 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 action of river flow and the terrain characteristics of the surrounding environment, the river slope environment often has dynamic changing characteristics. River slopes are not only an important part of the ecosystem, but also involve soil and water conservation, flood control and disaster relief. In order to ensure soil and water conservation on river slopes, sampling is required on the river slopes.

[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

A T-shaped rod 34 is vertically provided on the top of the sealing plate 33.

[0041] Furthermore, 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 upwards, indicating that the sampling barrel has reached the specified depth. The gas inside the cylindrical groove 38 on the indicator plate 22 will also be released into the liquid in the form of bubbles and float upwards, indicating that the water quality sampling is completed.

[0042] Please see the attached Figure 1 -Attached Figure 9In a preferred embodiment, the mud sampling component includes: an arc-shaped groove 32, the arc-shaped groove 32 is provided with the bottom of the sampling disk 2, a mud sampling roller 39 is rotatably installed inside the arc-shaped groove 32, and a bottom contact plate 23 is horizontally provided below the sampling disk 2, a feed groove is provided on the surface of the mud sampling roller 39, a turntable is rotatably installed on the surface of the sampling disk 2, and the center of the turntable end face is fixedly installed at the center of the end of the mud sampling roller 39 through a connecting shaft, an inner cavity 25 is provided inside the sampling disk 2, and a rotating mechanism for touching the bottom and rotating the mud sampling roller 39 is provided inside the inner cavity 25, and the rotating mechanism includes: a rotating shaft 30, the rotating shaft 30 is horizontally rotatably installed on one side of the inner cavity 25, and the center of the end of the rotating shaft 30 is fixed by a connecting shaft It is installed at the center of the end of the mud sampling roller 39, and the top of the rotating shaft 30 is sleeved with a one-way bearing 29, the outer ring surface of the one-way bearing 29 is fixedly sleeved with a gear 28, and the surface of the rotating shaft 30 is sleeved with a torsion spring 31, and the two ends of the torsion spring 31 are respectively installed on the side of the gear 28 and one side of the inner cavity 25. A slide plate 24 is vertically provided inside the inner cavity 25, and a third spring rod 26 is vertically fixedly installed on the top of the inner cavity 25, and the telescopic end of the third spring rod 26 is fixedly installed on the top of the slide plate 24. The bottom of the slide plate 24 passes through the sampling tray 2 and is fixedly installed on the top of the bottom contact plate 23. The slide plate 24 is hinged with a plurality of convex teeth 27 evenly distributed in a straight line through a one-way elastic hinge, and part of the slide plate 24 has teeth;

[0043] Preferably, the one-way rotation of the gear 28 drives the rotating shaft 30 to rotate one circle through the one-way bearing 29, and the rotation of the rotating shaft 30 drives the mud roller 39 to rotate one circle, thereby shoveling the silt at the bottom of the slope into the inside of the mud roller 39.

[0044] Please see the 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. A V-shaped frame 5 for facilitating pulling is installed on the top of the surface of the sampling barrel 1;

[0045] As mentioned above, when the 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 touch the ground, the convex teeth 27 and the gear 28 do not touch), and the sludge inside the sludge roller 39 can be discharged and collected.

[0046] 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 is caused to generate tension until the sealing disk 33 contacts the bottom of the sampling barrel 1. Due to the arrangement 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 card 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, and the gas above the sealing disk 33 in the sampling barrel 1 is in The valve is then closed, and the indicator block 21 and the indicator plate 22 are lifted upward by the two U-shaped handles to generate tension in the second spring rod 20, so that gas is contained in the two cylindrical grooves 38. The second spring rod 20 then resets the indicator block 21 and the indicator 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, thereby adjusting the horizontal distance of the connecting rope 8 and enabling sampling of water quality at different depths.

[0047] Then place the sampling bucket 1 on the river bank. First, the gas inside the mud roller 39 will be discharged through the through hole opened on the mud roller 39, and the buoy 7 will float on the liquid surface. When the sampling bucket 1 and the sampling plate 2 are all in the liquid surface, as the sampling bucket 1 and the sampling plate 2 continue to move downward, the connecting rope 8 will gradually tighten. When the connecting rope 8 is tightened, the sampling bucket 1 and the sampling plate 2 move downward again, and 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. When the pump 1 is in the closed position, the piston rod 6 is released, and the gas in the cylindrical groove 38 on the upper surface of the piston rod 6 is released, and the gas in the cylindrical groove 38 on the upper surface of the piston rod 6 is released into the liquid and floats upward. When the staff sees bubbles again, it indicates that the water sampling is completed and the sampling barrel 1 and the sampling disc 2 can be moved downward to sample the silt.

[0048] As the sampling disc 2 moves downward, the bottom plate 23 will contact the silt at the bottom of the slope and stop moving, then the slide plate 24 and the convex teeth 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 teeth 27 and the gear 28 are not in contact at the beginning. Due to the arrangement of the slide plate 24 and the convex teeth 27, when the gear 28 moves downward and contacts the convex teeth 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 teeth 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, and the gear 28 is 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 action of gravity, the mud sampling roller 39 can always be in a state where the feed trough is facing upward after the mud is sampled. 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 the mud is sampled. Finally, the sampling bucket 1 and the sampling plate 2 can be lifted away from the liquid surface to complete the sampling.

[0049] In summary, the water quality and silt at the slope can be sampled simultaneously, 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.

[0050] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
