[0002] Debris flow refers to a special flood that carries a large amount of solid substances such as sediment, stones, and boulders generated in a gully or on a hillside due to precipitation (rainstorm, glacier, snowmelt water). Its water and sediment convergence processes are very complex and are the product of the combined action of various natural and / or human factors. Debris flow has the characteristics of suddenness, fast flow velocity, large flow rate, large material capacity, and strong destructive power. When a debris flow occurs, it often washes away transportation facilities such as highways and railways, and even villages and towns, causing huge losses.

Detailed implementation manners

[0023] The following further elaborates on this application in conjunction with the attached Figures 1-3 drawings for a more detailed description.

[0024] An embodiment of this application discloses a tailings debris flow simulation experimental device. The device includes an experimental rack 11. A flow plate 12 is provided on the right side of the experimental rack 11. One side of the flow plate 12 close to the experimental rack 11 is higher, and a monitoring device 13 is provided on the other side. A mounting plate 21 is provided on the experimental rack 11. A telescopic rod 22 is provided on the mounting plate 21 in the vertical direction. The top end of the telescopic rod 22 is provided with a top plate 23. An insertion plate 231 is provided on the right side of the top plate 23. A concave plate 25 is slidably connected to the insertion plate 231 in the horizontal direction. A slot 27 for accommodating the insertion plate 231 is provided on the concave plate 25, and the insertion plate 231 is located in the slot 27. A sprinkler head 251 and a limiting component for moving itself are provided on the concave plate 25. When simulating debris flow, the posture and position of the concave plate 25 are changed according to needs, so as to change the form of precipitation, and thus more comprehensively simulate the debris flow situation.

[0025] To strengthen the overall firmness, a reinforcement plate 34 is further provided between the insertion plate 231 and the top plate 23. The reinforcement plate 34 is a triangular wedge. There are two reinforcement plates 34. One of the reinforcement plates 34 is located below the insertion plate 231, and the two reinforcement plates 34 are arranged oppositely.

[0026] In the embodiment of this application, the first limiting component includes two first screws 26. The two first screws 26 are threadedly penetrated through the two sides of the concave plate 25 in the width direction. The two first screws 26 are arranged oppositely. At the same time, a slide groove 24 for the first screw 26 to slide is provided on the insertion plate 231. When it is necessary to change the position and posture of the concave plate 25, rotate the first screw 26 to make it away from the slide groove 24, and the position of the concave plate 25 can be freely adjusted. At the same time, the angle of the concave plate 25 can also be changed, so as to change the angle and position of rainfall. After the adjustment is completed, rotate the first screw 26 to make its end abut against the side wall of the slide groove 24, so as to fix the posture and position of the concave plate 25 through friction. To enhance stability, friction pads for increasing friction are also provided on the two side walls of the slide groove 24 close to the first screw 26.

[0027] Meanwhile, the top plate 23 can also rotate on the telescopic rod 22, and the rotation axis is arranged in the vertical direction. Similarly, a second limiting component for restricting its own rotation is also provided on the top plate 23. In the embodiment of the present application, the second limiting component includes a second screw rod 35 and an abutting plate 36. The second screw rod 35 is threadedly penetrated through the telescopic rod 22 in the vertical direction, and the abutting plate 36 is fixedly connected to the top end of the second screw rod 35. Rotate the second screw rod 35 to make the abutting plate 36 approach or move away from the top plate 23; when it is necessary to rotate the top plate 23, make the abutting plate 36 move away from the top plate 23, and then after rotating the bottom plate in place, make the abutting plate 36 abut tightly against the top plate 23, and the rotation of the top plate 23 can be prevented by friction; similarly, in order to increase the friction, an anti-slip soil layer is also coated on the abutting plate 36.

[0028] Finally, a protective frame 31 is also provided on the fixed part of the telescopic rod 22. A receiving cavity for receiving the concave plate 25 is formed in the protective frame 31. When the device is not needed, the concave plate 25 can be removed as a whole and placed in the receiving cavity.

[0029] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
