Description

Technical Field

[0001] This utility model relates to the field of runoff sediment sampling technology, specifically a water and soil conservation runoff sediment sampling device. Background Technology

[0002] Runoff refers to the flow of water along the surface or underground under the influence of gravity, such as rainfall, snowmelt, or irrigation water. There are different types of runoff. According to the source of the water flow, there can be rainfall runoff, meltwater runoff, and irrigation runoff. According to the flow mode, there can be surface runoff and underground runoff. Surface runoff is further divided into slope runoff and channel runoff. In addition, there is solid runoff formed by water containing solid substances, and ionic runoff formed by water containing chemically dissolved substances. Therefore, some testing personnel often continuously sample and preserve runoff sediment.

[0003] For example, CN 221464941 U discloses a soil and water conservation runoff sediment sampling device, including a base plate, a U-shaped frame fixedly installed on the top of the base plate, sampling cylinders slidably connected to both sides of the inner wall of the U-shaped frame, a folded tube provided on the outer wall of the sampling cylinder, and a connector fixedly connected to one end of the folded tube; a transparent cylinder is snapped into the top of the base plate, one end of the connector is in contact with the transparent cylinder, a scale line is provided on the outer wall of the transparent cylinder, a threaded rod is threaded through the bottom of the transparent cylinder, and a piston plate is slidably connected to the inner wall of the transparent cylinder. Through the sampling cylinder, threaded rod, piston plate, scale line and transparent cylinder, rotating the threaded rod drives the piston plate to rise and fall, and cooperating with the scale line to make the piston plate rise and fall to a suitable position. Runoff sediment enters the transparent cylinder through the sampling cylinder and folded tube to complete the sampling, thereby facilitating quantitative sampling of runoff sediment and improving the accuracy of experimental data.

[0004] However, while this type of water and soil conservation runoff sediment sampling equipment can conveniently sample flowing sediment, it does not effectively block the surrounding area of ​​the sampling area. This can cause water flow to erode the sediment in the sampling area, affecting the stability of the equipment's sediment sampling.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a water and soil conservation runoff sediment sampling device. Utility Model Content

[0009] Furthermore, the conveying inclined plate is positioned on the motion trajectory of the sampling roller, and the sampling cylinder is positioned at the lower part of the inclination of the conveying inclined plate.

[0022] Furthermore, a lifting groove is provided at the connection between the inner wall of the equipment body 1 and the lifting rod 4. Two sets of connection boxes 7 are provided, and the positions of the two sets of connection boxes 7 are symmetrical about the central axis of the equipment body 1.

[0023] Furthermore, the conveying inclined plate 8 is set on the movement trajectory of the sampling roller 6, and the sampling cylinder 9 is set at the lower part of the inclination of the conveying inclined plate 8, which is conducive to the convenient conveying and sampling of mud and sand by setting the conveying inclined plate 8 on the movement trajectory of the sampling roller 6.

[0024] Furthermore, the adjusting block 12 forms a sliding structure with the slide groove 13 through the bolt 18, which facilitates the rotation of the bolt 18 and drives the adjusting block 12 to slide along the inner wall of the slide groove 13, thereby providing a convenient way to adjust the blocking position of the blocking plate 16.
