As the hydraulic cylinder 3 operates, the flap assembly 4 provided at the output end of the hydraulic cylinder 3 can be displaced toward the interior of the test box 5, so that the slope soil can be shaped.

[0038] like Figure 2-Figure 4 As shown, a push frame 31 is provided between the output end of the hydraulic cylinder 3 and the flap assembly 4, and the flap assembly 4 can be pushed to one side by the push frame 31. At the same time, the flap assembly 4 includes a push plate 41, and worm gears 42 are provided on both sides of the bottom of the push plate 41, and a flip frame 312 is provided at both ends of the push frame 31. The worm gear 42 can be provided inside the flip frame 312 and rotate with it as an axis. A worm 313 is meshed on one side of the outer peripheral surface of the worm gear 42, and one end of the worm 313 is rotated by the motor 314. As the motor 314 rotates, the worm 313 can drive its worm gear 42, and then the push plate 41 can be flipped with the worm gear 42 as the axis, and then the required slope angle can be adjusted. With the push of the hydraulic cylinder 3 and the extrusion of the push plate 41, the required slope angle can be achieved.

[0039] like Figure 2-Figure 8As shown, a drainage hole 58 is provided downwardly through one side of the inner bottom surface of the test box 5, and the excess solution can be discharged through the drainage hole 58 when the watering box 2 is spraying water to simulate the rainfall test. The upper surface of the driving box 11 opposite to the test box 5 is also provided with a corresponding through hole 15, and a drainage pipe 17 is extended to one side at the opening of the through hole 15, and the solution can be guided to flow to one side through the drainage pipe 17. At the same time, sprocket wheel 141 and sprocket wheel 2 143 are arranged side by side on both sides of the inner side of the driving box 11, and the two opposite sprocket wheels 1 141 are connected at the center of the circle by the rotating shaft 14, and the other two opposite sprocket wheels 2 143 are connected at the center of the circle by the crankshaft 144. At the same time, a chain 142 is sleeved between the outer peripheral surfaces of the sprocket wheel 141 and the sprocket wheel 2 143, and the chain 142 can make the sprocket wheel 141 and the sprocket wheel 2 143 rotate together. A connecting frame 311 is extended from the upper surface of the chain 142 on one side of the bottom of the push frame 31, and the moving groove 16 opened on the upper surface of the driving box 11 can make the connecting frame 311 move along its path.

[0040] A dredging column 173 capable of telescopic displacement is arranged inside the drainage hole 58, and the opening of the drainage hole 58 can be telescopically dredged by the dredging column 173, and the dredging column 173 is at the lowest point of the drainage hole 58 in the initial position to prevent the dredging column 173 from affecting the drainage of the drainage hole 58. The end of the dredging column 173 extends downward and penetrates the guide hole 171 opened on the surface of the drainage pipe 17, and a lifting plate 172 is fixedly arranged at the end of the dredging column 173, and a push rod 175 extends downward at the bottom of the lifting plate 172, and the push rod 175 is connected to the crankshaft 144 through a connecting rod 174. When the sample soil inside the test box 5 needs to be subjected to a slope test, the motor 314 can be operated at this time, and the worm 313 arranged at one end can be rotated as the motor 314 operates, and the worm 313 can be engaged with the worm wheel 42 arranged above after the worm 313 rotates, and then the push plate 41 can be adjusted to the required slope angle. A connecting frame 311 is arranged below the push frame 31, and the connecting frame 311 can drive the chain 142 arranged below to operate together, and then the sprocket 2 143 can rotate together. As the sprocket 2 143 rotates, the crankshaft 144 rotates, and the lifting plate 172 can be continuously extended and displaced through the connecting rod 174 and the push rod 175, and then the drainage hole 58 is dredged through the dredging column 173, so that the test box 5 can maintain the circulation of the solution when conducting the test.

[0041] like Figure 3-Figure 8As shown, the front of the test box 5 is sealed with a sealing cover 51, and after removing the sealing cover 51, the sample soil inside the test box 5 can be removed. A transparent plate 53 is provided on the surface of the test box 5 opposite to the sealing cover 51, and the relevant camera can record and shoot through the transparent plate 53. A sprocket 4 145 is provided on one side of the sprocket 2 143, and a double-headed sprocket 57 is provided on the surface of the transparent plate 53 in the area opposite to the sprocket 4 145. At the same time, a guide column 55 is also provided on the surface of the transparent plate 53, and the double-headed sprocket 57 can be guided by the guide column 55. The chain 2 146 that is sleeved on the outer peripheral surface of the sprocket 4 145 can be guided. At the same time, a rotatable sprocket 3 56 is provided on the front of the guide column 55 on one side, and a chain 3 571 is sleeved between the sprocket 3 56 and the double-headed sprocket 57, and a scraper 54 is also provided on one side of the chain 3 571, and the surface of the transparent plate 53 can be scraped clean by the scraper 54. The limiting column 52 arranged on one side of the surface of the transparent plate 53 penetrates one end of the scraper 54, and then can limit the lifting and lowering of the scraper 54. When the push plate 41 moves toward the inside of the test box 5 to squeeze the test soil sample, the crankshaft 144 rotates to make the sprocket wheel 145 arranged at one end rotate together. As the sprocket wheel 145 rotates, the double-headed sprocket wheel 57 can be rotated through the chain 146. After the double-headed sprocket wheel 57 rotates, the scraper 54 can be moved downward through the chain 3 571. As the scraper 54 moves downward, the surface of the transparent plate 53 can be scraped, and then the transparency of the transparent plate 53 can be maintained, so as to facilitate the relevant camera to shoot and record.

[0042] like Figure 4 and Figure 9-13 It is shown that when the push plate 41 adjusts the angle to squeeze the test soil sample, the top of the test soil sample is not compacted, which will affect the test simulation. The top of the push plate 41 is provided with two flip frames 43, and a telescopic plate 44 is hinged between the two flip frames 43. At the same time, a lifting hole 441 is provided downwardly at the top of the telescopic plate 44, and a telescopic plate 45 capable of telescopic displacement is provided through the lifting hole 441. The bottom of the watering box 2 is provided with chute 24 upwardly, and the sliders 446 provided on the top of the telescopic plate 45 are slidably provided inside the chute 24, so that the telescopic plate 45 can be displaced laterally along the length of the chute 24.

[0043] At the same time, a rotating shaft 1 443 that can rotate is passed through the upper part of the telescopic plate 2 45, and gears 2 444 are respectively provided at both ends of the rotating shaft 1 443, and the racks 23 provided on both sides of the slide slot 24 are meshed and connected with the gears 2 444. At the same time, a gear 1 445 is provided in the middle of the rotating shaft 1 443, and the rotating shaft 2 6 provided inside the telescopic plate 2 45 is provided below the gear 1 445, and the crown gear 1 61 provided on the top of the rotating shaft 2 6 is meshed and connected with the gear 1 445. A rectangular hole 62 is opened upward from the bottom of the rotating shaft 2 6, and a rectangular column 442 extends upward from the bottom of the lifting hole 441, and one end of the rectangular column 442 extends to the inside of the rectangular hole 62. And the rectangular column 442 is rotatably provided.

[0044] At the same time, a shovel plate 46 is arranged on one side of the outer surface of the telescopic plate 1 44. The bottom of the shovel plate 46 is arranged in an open shape, and a tamping plate 7 is arranged at the opening. A convex block 72 is also arranged on the top of the tamping plate 7. A rotatable cam 741 is arranged at the corresponding position above the convex block 72. The convex block 72 can be continuously pressed down as the cam 741 rotates. A rotating shaft 3 74 is arranged on one side of the surface of the cam 741 and extends to the inside of the lifting hole 441. A gear 3 75 is arranged at one end of the rotating shaft 3 74 located inside the lifting hole 441. The gear 3 75 is meshed and connected with the crown gear 2 447 arranged on the outer peripheral surface of the rectangular column 442. A spring 73 is arranged between the top of the tamping plate 7 and the bottom of the shovel plate 46. At the same time, the lifting cylinders 71 arranged at the four corners of the top of the tamping plate 7 are connected to the bottom of the shovel plate 46. When the push plate 41 is flipped to one side at an angle, the telescopic plate 1 44 can move downward with the push plate 41. As the hydraulic cylinder 3 operates to push the push plate 41, the shovel plate 46 can shovel away the excess sample soil on the top of the sample soil, and when the telescopic plate 2 45 moves to one side with the push plate 41, the gear 2 444 is driven to rotate by the rack 23, and then the rotating shaft 1 443 rotates and drives the rotating shaft 2 6 through the gear 1 445. As the rotating shaft 2 6 rotates, the rectangular column 442 can rotate together, and after the rectangular column 442 rotates, the crown gear 2 447 can drive the meshing gear 3 75 above. After the gear 3 75 rotates, the cam 741 set at one end rotates together through the rotating shaft 3 74, and after the cam 741 rotates, the protrusion 72 is continuously squeezed downward, and then the top of the test sample soil that has been pushed and shoveled is continuously tamped through the tamping plate 7, so as to facilitate subsequent test simulation.

[0045] Specifically, the working principle of the soil slope instability simulation test device based on rainfall intensity is as follows: when the soil sample inside the test box 5 needs to undergo a slope test, the motor 314 can be operated at this time, and as the motor 314 operates, the worm 313 set at one end can be rotated, and after the worm 313 rotates, it can engage with the worm wheel 42 set above, and then the push plate 41 can be adjusted to the required slope angle. A connecting frame 311 is arranged below the push frame 31, and the connecting frame 311 can drive the chain 142 set below to operate together, and then the sprocket 2 143 can rotate together, and as the sprocket 2 143 rotates, the crankshaft 144 rotates, and the lifting plate 172 can be continuously telescopically displaced through the connecting rod 174 and the top rod 175, and then the drainage hole 58 is dredged through the dredging column 173, so that the test box 5 can maintain the circulation of the solution when conducting the test;

[0046] As the crankshaft 144 rotates, the sprocket wheel 4 145 arranged at one end can rotate together. After the sprocket wheel 4 145 rotates, the double-headed sprocket wheel 57 can be rotated through the chain 2 146. After the double-headed sprocket wheel 57 rotates, the scraper 54 can be displaced downward through the chain 3 571. After the scraper 54 is displaced downward, the surface of the transparent plate 53 can be scraped, and then the transparency of the transparent plate 53 can be maintained, so as to facilitate the relevant camera equipment to shoot and record;

[0047] When the push plate 41 is flipped to one side at an angle, the telescopic plate 1 44 can move downward with the push plate 41. After the hydraulic cylinder 3 operates to push the push plate 41, the shovel plate 46 can shovel away the excess sample soil on the top of the sample soil, and when the telescopic plate 2 45 moves to one side with the push plate 41, the gear 2 444 is driven to rotate by the rack 23, and then the rotating shaft 1 443 rotates and drives the rotating shaft 2 6 through the gear 1 445. As the rotating shaft 2 6 rotates, the rectangular column 442 can rotate together, and after the rectangular column 442 rotates, the crown gear 2 447 can drive the meshing gear 3 75 above. After the gear 3 75 rotates, the cam 741 set at one end rotates together through the rotating shaft 3 74, and after the cam 741 rotates, the protrusion 72 is continuously squeezed downward, and then the top of the test sample soil that has been pushed and shoveled is continuously tamped through the tamping plate 7, so as to facilitate subsequent test simulation.

[0048] It should be noted that the specific model specifications of the water pump 22 and the motor 314 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0049] The power supply and principle of the water pump 22 and the motor 314 are clear to those skilled in the art and will not be described in detail here.
