DETAILED DESCRIPTION

[0034] Please refer to Figures 1-9 The technical scheme provided by the present application is as follows: a water tank part and a simulation part are included, the water tank part includes a base 1, multiple sets of adjusting rods 2, and a soft tank 3;

[0035] The adjusting rod 2 is fixedly connected at the bottom with a sliding block 7 and at the top with a fixed fork 5, the fixed fork 5 is rotationally connected with a floating fork 6 inside, the floating fork 6 is used for rotating along with the shape of the soft tank 3 and adhering to the bottom of the soft tank 3, and the sliding block 7 is slidingly distributed in the base 1;

[0036] The soft tank 3 is fixedly connected at both ends with end tanks 4, the end tanks 4 are fixedly connected with the floating forks 6 of the adjusting rods 2 located at both ends respectively, and the floating fork 6 in the middle is located at the bottom of the soft tank 3 to play a supporting role, and the length of the adjusting rod 2 is adjustable for adjusting the height distribution of the soft tank 3;

[0037] The simulation part includes an erecting rod 8 fixedly connected at the top of the base 1 and a water tank 9 installed, the erecting rod 8 is installed at the top with a spraying plate 10, the water tank 9 is communicated with the spraying plate 10, and the spraying plate 10 is located above the soft tank 3 for simulating rainfall.

[0038] The device needs to adjust the slope and trend of the soft groove 3 of the water tank part according to the simulated groove state before use, so that the soft groove 3 is closest to the actual simulated slope surface to obtain more accurate data; the groove condition of the soft groove 3 can be adjusted to simulate various slope conditions, such as simulation of steep slope, simulation of sudden change of slope angle and simulation of curved slope, etc., which can accurately restore the accumulation condition of the spoil ground, and then obtain more accurate data for targeted prevention and control of debris flow. And the soft groove 3 is integrally formed, and there is no gap and interface in the adjustment deformation process, so there is no problem of liquid leakage and slurry leakage, and the adjustment is always smooth.

[0039] Specifically, by adjusting the length of each adjusting rod 2, the fixed fork 5 of the adjusting rod 2 supports the soft groove 3 at different heights, so that the soft groove 3 is bent into the desired trend; after the height of the adjusting rod 2 is adjusted, the floating fork 6 will naturally rotate to the state of being attached to the bottom of the soft groove 3, thereby enhancing the support effect of the soft groove 3, making the bottom trend smooth, and also ensuring that the material of the debris flow can be supported.

[0040] After adjusting the trend of the soft groove 3, the spray plate 11 is opened to spray water, thereby simulating the situation of heavy rain and rainstorm. The sprayed water falls into the soft groove 3, and the two can simulate the situation of debris flow under heavy rain and rainstorm.

[0041] The adjusting rod 2 can be an electrically driven push rod or a telescopic cylinder, and each group of adjusting rods 2 needs to be equipped with a set of motor, thereby realizing individual control. This method is more accurate, but the cost is higher, and needs to be used with a good control system.

[0042] Please refer to Figures 5-9 , the adjusting rod 2 is manually driven, which can save cost and is easy to adjust. Specifically, by stepping on the air pump 17, the gas in the air pump 17 pushes open the one-way valve 16 and enters the moving cylinder 12 between the fixed cylinder 11 through the hole 13 of the outer branch pipe 14. With the entry of the gas, the moving cylinder 12 is lifted upwards, thereby changing the length of the adjusting rod 2 and changing its support height. This method can be adjusted individually while standing, thereby obtaining the desired groove trend condition, and has good freedom and flexibility. It is also relatively safe in the case of simulating rainwater above.

[0043] When the inflator 17 sends gas into the hole 13 through the outer branch pipe 14, the gas first acts on the open disc 22, and then pushes the open disc 22 forward to open the air inlet ring 18, and the middle rod 20 and the closed ball 21 also move forward, and then the one-way valve 16 is opened, the gas path of the outer branch pipe 14 is opened, and the gas enters the hole 13. After adjustment, under the weight of the moving cylinder 12 and its support and the action of the one-way spring 23, the closed ball 21 is tightly blocked at the outlet of the conical seat 19, and the open disc 22 is tightly attached to the air inlet ring 18. The two sealing blocks make the gas in the fixed cylinder 11 and the moving cylinder 12 unable to be discharged in the opposite direction, so that the fixed cylinder 11 and the moving cylinder 12 remain in the adjusted position, and then the soft body groove 3 is stably supported.

[0044] When the simulation is completed, the new groove direction needs to be adjusted. By pressing down the valve rod 25, the circular block 26 is moved downward, the release pipe 24 is opened, the gas between the fixed cylinder 11 and the moving cylinder 12 can be discharged from the release pipe 24, so that the moving cylinder 12 can naturally descend, and then the support height of each adjusting rod 2 can be adjusted individually, and the required groove direction can be quickly adjusted. By pressing the pressing plate 29, all valve rods 25 can be pressed down at the same time, and all adjusting rods 2 can be uniformly restored to the initial height, which is convenient, fast and flexible.

[0045] Under normal circumstances, the valve rod 25 is lifted upward by the sealing spring 27, so that the circular block 26 maintains the state of closing the release pipe 24, thereby ensuring the normal gas inlet of the inflator 17 and the outer branch pipe 14. The retaining spring 30 also makes the pressing plate 29 in the raised state to avoid accidental touch.

[0046] Among them, the adjacent two of the adjusting rod 2 are connected by the chain plate 31, the bottom slide rod 32 is fixedly connected in the base 1, the bottom slide rod 32 passes through the sliding block 7 and is in sliding fit with the sliding block 7, the clamping plate 33 is slidably arranged on both sides of the base 1, the clamping plate 33 is located at both ends of all sliding blocks 7, the clamping screw 34 is installed in the base 1, and the clamping screw 34 passes through the clamping plate 33 and is used to drive the clamping plate 33 to move synchronously to clamp or release the sliding block 7.

[0047] Because the floating fork 6 of the front and back end is fixedly connected with the two ends of the soft groove 3, and the end is provided with the hard groove connected with the soft groove 3, the two ends can be well adapted and adjusted to obtain the required groove shape through the mode of pulling the middle support. In the adjustment process, the distance between the two adjacent adjusting rods 2 can be controlled to be relatively uniform and not to be suddenly changed through the connection of the chain plate 31, so that the middle adjusting rod 2 can uniformly support the soft groove 3, and the distance between the two adjacent adjusting rods 2 will not be suddenly changed under the impact of the adjustment of the groove direction and the debris flow, so as to avoid pulling the soft groove 3 and more gently and orderly adjust. At the same time, the traction of the chain plate 31 can also make the adjacent adjusting rod 2 be adapted and changed when one adjusting rod 2 is adjusted, so that the slope adjustment is more rapid. After the experiment is completed, the closed door plate 37 can be opened, and the internal debris flow material can be discharged or cleaned, which is more convenient.

[0048] In the specific simulation experiment, corresponding detection equipment can be installed on the installation table 35, such as a camera, a flow rate sensor, a pressure sensor, a data collection and analysis device, a rain gauge, an optical fiber sensor, a water content sensor, a pore pressure sensor, etc., to provide a better equipment installation adaptation occasion.

[0049] Please refer to Figures 1-3 , specifically, in the process of spraying the simulated heavy rain by the spraying plate 10, the rainwater leaked outside the groove and splashed outside the groove will be received by the water receiving box 36, so as to avoid the water falling on the equipment or the ground below, protect the equipment, and at the same time, be beneficial to the cleanliness of the ground, avoid slipping, and be beneficial to safe operation; at the same time, the water received by the water receiving box 36 can be recycled in the water tank 9 through the hose for circular spraying.
