Technical Field

[0001] The utility model relates to the technical field of multi-stage sand-trapping for soil and water conservation, in particular to a multi-stage sand-trapping device for soil and water conservation. Background Art

[0002] Soil and water conservation refers to the prevention and control measures taken against soil erosion caused by natural factors and human activities. At present, a large amount of sediment often accumulates on the slopes at both ends of the river. The sediment flows into the river and accumulates, which will lead to a decrease in flow. Therefore, sand guardrails are installed on the edge for prevention and control.

[0003] Authorization announcement number: CN218060250U discloses a multi-stage sand-trapping device for soil and water conservation. After the user of the sand-trapping device fixes the lower baffle, the user movably connects one end of the support screw with the upper baffle. The user rotates the support screw sleeve, and the limit block and the limit groove limit the support screw, so that the support screw moves to the outside of the support column, and the length of the support column and the support screw is adjusted so that the movable seat at the lower end of the support column can be connected to the ground, so that the support column, the support screw, the upper baffle, the lower baffle and the ground are distributed in a triangle, which is convenient for supporting the upper baffle and the lower baffle.

[0004] However, when the sand-trapping device supports the upper and lower baffles through the support column and the support screw, since one end of the support screw is connected to one side of the upper baffle, the support screw and the support column are limited to supporting one position of the upper baffle, and it is inconvenient to support the lower baffle, which makes the support column and the support screw have poor support effect on the lower baffle, resulting in the lower baffle being easily broken during the sand-trapping process, affecting the normal use of the sand-trapping device. Therefore, it is necessary to provide a new soil and water conservation multi-stage sand-trapping device to solve the above technical problems. Utility Model Content
