DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Refer to the attached specification Figure 1-3 The utility model is a slope sediment runoff scouring experimental device simulating vegetation density, comprising a bottom plate 1, see Figure 2 The top of the bottom plate 1 is fixedly connected to a support frame 2, a connecting member 3 is arranged inside the support frame 2, a rotating member 4 is fixedly connected to the outer wall of the connecting member 3, the rotating member 4 is inserted into the inside of the support frame 2, and an angle ruler 5 is rotatably connected to the outer wall of the rotating member 4, see Figure 1 The angle ruler 5 is inserted into the inside of the support frame 2, a scale line 6 is opened on one side of the connecting piece 3, and the scale line 6 is set on one side of the angle ruler 5. A placement piece 7 is fixedly connected to one side of the connecting piece 3, and a hinge rod 8 is hinged at the bottom of the placement piece 7. The end of the hinge rod 8 away from the placement piece 7 is hinged to a hinge piece 9, and the hinge piece 9 is slidably connected to the top of the base plate 1.

[0022] It should be noted that, when the staff needs to conduct a runoff scouring experiment on the sediment on the slope with different vegetation densities, the staff can first use the ring knife method to take the soil with a suitable vegetation density, and put it into the interior of the placement piece after cutting it to the same size as the placement piece 7. Then the staff can rotate the rotating wheel 11 to make the rotating wheel 11 drive the threaded rod 10 to rotate, and then the threaded rod 10 drives the hinged piece 9 to slide along the top of the bottom plate 1, so that the hinged piece 9 drives the placement piece 7 and the connecting piece 3 to rotate with the rotating piece 4 as the rotation center through the hinged rod 8. , let the connecting piece 3 drive the scale line 6 to rotate. The rotation of the scale line 6 will change its position on one side of the angle ruler 5. At this time, the staff can determine the angle of the placement piece 7 in real time by observing the position of the scale line 6 and the angle ruler 5, thereby determining the slope of the placement piece 7, so as to facilitate the staff to adjust the slope of the placement piece 7 and know the slope angle, and facilitate the staff to use the experimental device to experiment with the sediment runoff of slopes with different slopes and different vegetation densities, without the staff having to adjust the slope of the placement piece 7 and then measure the slope.

[0023] Embodiment 2: The interior of the hinge 9 is connected to a threaded rod 10 by a thread, and the threaded rod 10 is rotatably connected to the interior of the bottom plate 1. One end of the threaded rod 10 is fixedly connected to a rotating wheel 11, and the rotating wheel 11 is arranged on one side of the bottom plate 1.

[0024] It should be noted that, when the staff has completed the preparations for the experiment, the staff can connect the soft water pipe 17 to the external water source through the connector 18, and then rotate the flow stabilizer 13 to allow the flow stabilizer 13 to be placed above the soil inside the placement piece 7. Then, the water source and the valve 16 can be opened to allow water to enter the water flow detector 15 through the connector 18, the soft water pipe 17, and the valve 16, so that the water flow detector 15 can monitor the water flow in real time, which is convenient for the staff to detect the water flow in the experiment and adjust it through the valve 16 when necessary. Water will fall into the inside of the water trough 14 through the water flow detector 15, and the water will accumulate in the water trough 14. When the water in the water trough 14 reaches a certain amount, the water will flow into the inside of the flow stabilizing groove 12, and then overflow the flow stabilizing groove 12 over time and flow through the flow stabilizing plate 13 to the top of the soil inside the placement piece 7 to flush the soil. Through the arrangement of the water trough 14, the flow stabilizing groove 12, and the flow stabilizing plate 13, the stability of the water is improved and the water can flow evenly into the top of the soil inside the placement piece 7 to flush the soil, so as to improve the stability of the experiment and prevent the water flow from being unstable and affecting the results of the experiment.
