Both sides of the box body 110 are provided with installation grooves, and the outlet tank shell 620 and the return tank shell 630 are respectively fixed and embedded in the installation groove, and the outer walls of the outlet tank shell 620 and the return tank shell 630 can be provided with sealing gaskets to improve the sealing effect; The opposite sides of the water tank shell 620 and the return tank shell 630 are respectively set to be open, and the openings of the outlet tank shell 620 and the return tank shell 630 are equipped with filter screens 631 to prevent larger particles of sediment from entering the circulation pump 610 . The vertical water outlet pipe 640 is set on the side of the water outlet tank shell 620 away from the box body 110, and several sets of horizontal water outlet pipes 660 are respectively connected to the box body 110 and the vertical water outlet pipe 640. The outside of the horizontal water outlet pipe 660 is provided with a fourth valve 661. The two ends of 680 are respectively connected to the outlet port of circulating pump 610 and the vertical outlet pipe 640. The vertical return pipe 650 is set on the side of the return tank shell 630 away from the tank 110. The two ends of several sets of horizontal return pipes 670 are respectively connected to the tank 110 and the longitudinal The return pipe 650 and the horizontal return pipe 670 are provided with a fifth valve 671 outside, and both ends of the return pipe 690 are connected to the water inlet port of the circulation pump 610 and the vertical return pipe 650 respectively.

It should be noted that the circulation pump 610 is an adjustable pressure water pump. The specific model specification of the circulation pump 610 mentioned above needs to be selected according to the actual specification of the device, etc. The specific model selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply of the circulating pump 610 and its principle are clear to those skilled in the art, and will not be described in detail here.

The circulation pump 610 starts, and the water source inside the tank 110 enters the interior of the circulation pump 610 from the return tank shell 630 through the horizontal return pipe 670, the vertical return pipe 650 and the return pipe 690; The horizontal water outlet pipe 660 enters into the water outlet tank shell 620 and flows out to the inside of the box body 110 . Both the backwater tank shell 630 and the water outlet tank shell 620 cause the water source flow inside the box body 110 to simulate the water source flow in the river. By adjusting the pressure of the circulation pump 610, the influence of different flow rates on the landslide body simulation part 210 can be adjusted and simulated.

In order to create the size of the water flow inside the box body 110 and the impact of water flow at different heights on the landslide body simulation part 210, it can be simulated by opening the fifth valve 671 outside the horizontal return pipe 670 and the fourth valve 661 outside the horizontal water outlet pipe 660. The impact of water flow at different heights on the landslide body simulation part 210. Moreover, the water flow simulation can also be tested in conjunction with the rise or fall of the water level to obtain more influences of the water flow and water level changes on the landslide body simulation part 210, thereby obtaining more abundant test data.
