Description

Technical Field

[0001] This application relates to the technical field of high - altitude landslide simulation devices. Specifically, it relates to a high - altitude landslide debris flow test model device. Background Art

[0002] High - altitude landslides often have a fast impact speed and a large area. Due to their high altitude and high speed, after the landslide body falls, it will form debris. Its impact on the ground is not a whole, but a debris flow composed of many rock blocks, which is the 'avalanche - landslide debris flow'. It causes a larger disaster range in the affected area. High - altitude landslide debris flow is a highly destructive geological disaster phenomenon, which exhibits complex mechanical behaviors and mass transfer laws during its movement.

[0003] In order to deeply study the initiation mechanism, movement process, accumulation characteristics, and the impact on the surrounding environment of high - altitude landslide debris flow, indoor simulation tests are required. However, the existing simulation devices have many deficiencies. Firstly, it is difficult to accurately control the angle of the slope body, so the movement of debris flow under different slopes cannot be obtained. Moreover, the roughness of the slope body will also affect the movement of debris flow. Therefore, the existing simulation devices cannot well simulate the movement of debris flow under different terrain conditions. Secondly, during the simulation test, it is very troublesome to adjust the angle of the slope body and the roughness of the slope body, and multiple corresponding adjustment components and adjustment knobs are required during the adjustment process, which makes the operation process very cumbersome and is not conducive to conducting experiments. These problems have restricted the in - depth study of high - altitude landslide debris flow and the formulation of effective prevention and control measures. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. For this purpose, this application proposes a high - altitude landslide debris flow test model device. The high - altitude landslide debris flow test model device can provide power for the slope - adjusting driving part or the slope - surface adjusting driving part according to needs during the simulation test through the driving part. During the experiment, it is more convenient to adjust the angle and the roughness of the slope body, reducing the driving structure required for the simulation device, making the components of the device fewer and the operation process more simple.

[0038] Next, a high-level landslide debris flow test model device according to an embodiment of the present application will be described with reference to the drawings.

[0039] Please refer to Figures 1 to 11 , a high-level landslide debris flow test model device according to an embodiment of the present application includes:

[0040] An operating bracket 1, the operating bracket 1 includes an upper flat plate and a lower support frame, and a rectangular window is provided in the left half of the upper flat plate of the operating bracket 1;

[0041] The landslide simulation body 2 is rotationally installed in the rectangular window on the upper side flat plate of the operation bracket 1;

[0042] The slope adjustment driving member 3 is fixedly installed on the upper right part of the operation bracket 1, and the slope adjustment driving member 3 can drive the landslide simulation body 2 to perform slope adjustment;

[0043] The slope surface adjustment driving member 4 is installed on the upper right part of the operation bracket 1, and the slope surface adjustment driving member 4 is located behind the slope adjustment driving member 3. The slope surface adjustment driving member 4 can drive the landslide simulation body 2 to perform slope surface change;

[0044] The driving member 5 is installed on the support rod under the operation bracket 1, and the driving member 5 can drive the slope adjustment driving member 3 and the slope surface adjustment driving member 4 to work.

[0045] In the present invention, the slope adjustment driving member 3 can adjust the slope of the landslide simulation body 2, so as to accurately control the angle of the slope body in the simulation test. The slope surface adjustment driving member 4 can adjust the slope surface change of the landslide simulation body 2, so as to be able to simulate the movement of the debris flow under different roughness of the slope surface. The driving member 5 can provide power for the slope adjustment driving member 3 or the slope surface adjustment driving member 4 according to needs in the simulation test. And when the driving member 5 is driven at a high speed, it can also drive the cleaning assembly 7 and the slope adjustment driving member 3 to work simultaneously, so that the landslide simulation body 2 can be cleaned during continuous reciprocating movement to remove the residual stains on the landslide simulation body 2.

[0046] In the present invention, a driving structure can be used to drive and adjust three components in the simulation test. During the experiment, it is more convenient to perform angle adjustment, roughness adjustment of the slope body, and cleaning of the simulation device, reducing the driving structure required for the simulation device, making the components of the device fewer and the operation process simpler.

[0047] Please refer to Figures 3 - 6, the landslide simulation body 2 includes a lower L-shaped plate 21, an upper L-shaped plate 22, a connecting frame 23, and a slope adjustment rotating shaft 27. A first rotating rod 25 is provided at the lower end of the lower L-shaped plate 21, and a second rotating rod 26 is provided at the upper end of the upper L-shaped plate 22. The first rotating rod 25 is rotatably installed in the rectangular window of the upper flat plate of the operation bracket 1. The lower L-shaped plate 21 and the upper L-shaped plate 22 are arranged away from each other. A connecting frame 23 is fixedly connected between the lower L-shaped plate 21 and the upper L-shaped plate 22. A slope adjustment rotating shaft 27 is rotatably installed between the lower L-shaped plate 21 and the upper L-shaped plate 22. A cross-shaped bracket 28 is fixedly installed on the slope adjustment rotating shaft 27. Square cylinders 29 are fixedly installed on the outer sides of the cross-shaped bracket 28. Rough plates with different roughnesses are respectively attached to the four outer side surfaces of the square cylinder 29. First baffles 210 are respectively fixedly installed on the four side edges of the square cylinder 29. Second baffles 24 are respectively fixedly installed on the front and rear sides of the lower L-shaped plate 21 and the upper L-shaped plate 22. By installing the square cylinder 29 between the lower L-shaped plate 21 and the upper L-shaped plate 22 and connecting the lower L-shaped plate 21 and the upper L-shaped plate 22 together through the connecting frame 23, the square cylinder 29 can be rotated between the lower L-shaped plate 21 and the upper L-shaped plate 22. When it is necessary to change the roughness of the slope, by driving the slope adjustment rotating shaft 27 to rotate, the square cylinder 29 can be rotated between the lower L-shaped plate 21 and the upper L-shaped plate 22, thereby changing the roughness of the slope. When it is necessary to change the slope of the slope, by driving the upper L-shaped plate 22 to move through the slope adjustment driving member 3, the inclination angle of the entire landslide simulation body 2 can be changed.

[0048] The upper end of the slope adjustment rotating shaft 27 penetrates through the upper L-shaped plate 22 and is fixedly installed with a first pulley 211. A rectangular plate 212 is fixedly installed on the rear side surface of the upper L-shaped plate 22. A second pulley 213 is rotatably installed on the rectangular plate 212. A first transmission belt 214 is installed between the second pulley 213 and the first pulley 211 for transmission. During use, by driving the second pulley 213 to rotate and under the transmission action of the first transmission belt 214, the first pulley 211 can be rotated, so that the slope adjustment rotating shaft 27 can be rotated.

[0049] Please refer to Figure 3, the slope adjustment driving member 3 includes a rectangular box body 31, a reciprocating lead screw 32, a moving block 33, a clamping block 35 and a driving arm 36. The rectangular box body 31 is fixedly installed on the right part of the upper flat plate of the operation bracket 1. A reciprocating lead screw 32 is rotatably installed between the left and right side walls inside the rectangular box body 31. A moving block 33 is threadedly connected to the reciprocating lead screw 32. The moving block 33 is movably installed inside the rectangular box body 31. Strip-shaped limiting grooves 34 are formed in the front and rear side walls of the rectangular box body 31. Clamping blocks 35 are fixedly connected to the front and rear side walls of the moving block 33. The clamping blocks 35 are movably clamped in the strip-shaped limiting grooves 34. A driving arm 36 is rotatably installed on the clamping blocks 35. The other end of the driving arm 36 is rotatably installed on the second rotating rod 26. The left end of the reciprocating lead screw 32 extends out of the rectangular box body 31 and is connected with a third pulley 37. The third pulley 37 can be driven to rotate by the driving component 5, so that the reciprocating lead screw 32 rotates. During the rotation of the reciprocating lead screw 32, the moving block 33 can be driven to move left and right. During the movement of the moving block 33, the rotation angle of the driving arm 36 can be changed, so that the driving arm 36 drives the landslide simulation body 2 to rotate.

[0050] Please refer to Figure 7 , the slope adjustment driving member 4 includes a supporting vertical plate 41, a fourth pulley 42, a first universal joint 43, a telescopic rod 44 and a second universal joint 45. The supporting vertical plate 41 is fixedly installed on the right part of the upper flat plate of the operation bracket 1, and the supporting vertical plate 41 is located at the left rear side of the rectangular box body 31. A fourth pulley 42 is rotatably installed at the upper end of the supporting vertical plate 41. A first universal joint 43 is fixedly installed on one side of the fourth pulley 42. A telescopic rod 44 is connected to the first universal joint 43. The other end of the telescopic rod 44 is connected with a second universal joint 45. The second universal joint 45 is fixedly installed on one side wall of the second pulley 213. When in use, the fourth pulley 42 can be driven to rotate by the driving component 5. Under the transmission of the first universal joint 43, the second universal joint 45 and the telescopic rod 44, the second pulley 213 can also be driven to rotate, and the telescopic rod 44 can change according to the inclination angle of the landslide simulation body 2. Therefore, no matter what inclination angle the landslide simulation body 2 is in, the slope adjustment driving member 4 can drive the second pulley 213 to rotate, so as to adjust the slope of the landslide simulation body 2.

[0051] Please refer to Figures 8 - 10, according to some embodiments of the present application, the driving component 5 includes a mounting plate 51, a C-shaped mounting frame 52, a first rotating shaft 511, a second rotating shaft 512, and a third rotating shaft 513. There are two mounting plates 51, and the two mounting plates 51 are symmetrically mounted on the lower surface of the upper side flat plate of the operation bracket 1. A C-shaped mounting frame 52 is fixedly mounted between the left and right mounting plates 51 on the lower surface of the upper side flat plate of the operation bracket 1. The rear part of the left mounting plate 51 is rotatably mounted with a first rotating shaft 511, the front part of the left mounting plate 51 is rotatably mounted with a second rotating shaft 512, and the front part of the right mounting plate 51 is rotatably mounted with a third rotating shaft 513. The right end of the first rotating shaft 511 is fixedly mounted with a first bevel gear 514, the right end of the second rotating shaft 512 is fixedly mounted with a second bevel gear 515, and the left end of the third rotating shaft 513 is fixedly mounted with a third bevel gear 516. The other ends of the first rotating shaft 511, the second rotating shaft 512, and the third rotating shaft 513 are respectively connected with ratchet connectors 53. A fifth pulley 517 is mounted on the ratchet connector 53 on the first rotating shaft 511, and a second transmission belt 46 is mounted for transmission between the fifth pulley 517 and the fourth pulley 42. A sixth pulley 518 is mounted on the ratchet connector 53 on the second rotating shaft 512, and a third transmission belt 38 is connected for transmission between the sixth pulley 518 and the third pulley 37. A pump body drive shaft 54 is connected to the ratchet connector 53 on the third rotating shaft 513. The opening of the C-shaped mounting frame 52 faces upward, and the vertical side plates of the C-shaped mounting frame 52 are arranged corresponding to the front and back. A fourth rotating shaft 521 is rotatably mounted between the front and back side walls of the C-shaped mounting frame 52. Fourth bevel gears 522 are fixedly mounted at the front and back ends of the fourth rotating shaft 521 respectively. The rear fourth bevel gear 522 is meshed and connected with the first bevel gear 514, and the front fourth bevel gear 522 is meshed and connected with the second bevel gear 515 and the third bevel gear 516. A drive motor 523 is fixedly mounted on the front side of the C-shaped mounting frame 52, and the rotating shaft of the drive motor 523 is connected to the front end of the fourth rotating shaft 521. When in use, the drive motor 523 can drive the fourth rotating shaft 521 to rotate. Since the first bevel gear 514, the second bevel gear 515, and the third bevel gear 516 are all meshed and connected with the corresponding fourth bevel gears 522, when the fourth rotating shaft 521 rotates, the first rotating shaft 511, the second rotating shaft 512, and the third rotating shaft 513 all rotate simultaneously. When the drive motor 523 rotates forward, the ratchet connector 53 on the first rotating shaft 511 performs rotational transmission, and the ratchet connectors 53 on the second rotating shaft 512 and the third rotating shaft 513 do not perform rotational transmission. At this time, the fifth pulley 517 can rotate, and the slope adjustment driving member 4 is rotationally driven through the second transmission belt 46.

[0052] When the drive motor 523 rotates in the reverse direction at a low speed, the ratchet connector 53 on the first rotating shaft 511 does not perform rotational transmission, while the ratchet connectors 53 on the second rotating shaft 512 and the third rotating shaft 513 perform rotational transmission. At this time, the sixth pulley 518 and the third rotating shaft 513 can rotate at a low speed. During the rotation of the sixth pulley 518, the slope adjustment drive member 3 can be rotationally driven through the third transmission belt 38. When the pump body drive shaft 54 rotates at a low speed, the impact on the operation of the cleaning assembly 7 is relatively small.

[0053] When the drive motor 523 rotates in the reverse direction at a high speed, at this time, the sixth pulley 518 and the third rotating shaft 513 can rotate at a high speed. During the rotation of the sixth pulley 518, through the transmission of the third transmission belt 38, the slope adjustment drive member 3 drives the moving block 33 to perform reciprocating motion along the reciprocating lead screw 32, and then the landslide simulation body 2 can be reciprocally lifted and lowered. And at this time, when the pump body drive shaft 54 rotates at a high speed, the cleaning assembly 7 can pump water to clean the landslide simulation body 2. During the cleaning process, the landslide simulation body 2 performs reciprocating rotational motion, which can generate vibration force on the surface of the landslide simulation body 2, facilitating the removal of stains on the surface of the landslide simulation body 2 and improving the cleaning effect of the cleaning assembly 7.

[0054] The ratchet connector 53 includes an outer sleeve 531, helical teeth 532, a rotating block 533 and a stop block 536. Connecting shafts for connection are connected to both the outer sleeve 531 and the rotating block 533. Helical teeth 532 are uniformly and fixedly installed on the inner side wall of the outer sleeve 531. The rotating block 533 is rotatably arranged inside the outer sleeve 531. A receiving groove 534 is formed on the side wall of the rotating block 533. A stop block 536 is movably installed in the receiving groove 534, and a spring 535 is installed between the stop block 536 and the bottom of the receiving groove 534.

[0055] Since a rough plate is bonded to the outer side surface of the square cylinder 29, after the simulation test, stains are likely to adhere to the rough plate. If not cleaned, it will affect the next simulation test. Please refer to Figure 2 and Figure 11, a water tank 6 is fixedly installed at the right end of the lower support frame of the operating bracket 1. A cleaning component 7 is fixedly installed on the water tank 6. The driving component 5 can drive the cleaning component 7 to work. The cleaning component 7 includes a cleaning pipe 71, a suction pump body 72, a suction fan blade 73, a water inlet pipe 74 and a water outlet pipe 75. The cleaning pipe 71 is fixedly installed on the connecting frame 23 in a U shape. Nozzles are evenly installed on the cleaning pipe 71. The suction pump body 72 is fixedly installed on the water tank 6. A suction fan blade 73 is rotatably installed in the suction pump body 72. The end of the pump body drive shaft 54 extends into the suction pump body 72 and is connected to the suction fan blade 73. The bottom of the suction pump body 72 is fixedly connected with the water inlet pipe 74. The other end of the water inlet pipe 74 extends into the water tank 6. The upper end of the front side of the suction pump body 72 is fixedly connected with the water outlet pipe 75. The end of the water outlet pipe 75 is connected to the cleaning pipe 71. The suction fan blade 73 can be driven to rotate by the pump body drive shaft 54. During the rotation of the suction fan blade 73, a negative pressure can be formed in the suction pump body 72, so that the aqueous solution in the water tank 6 enters the suction pump body 72 along the water inlet pipe 74, and then is conveyed out through the water outlet pipe 75. The aqueous solution is conveyed into the cleaning pipe 71 through the water outlet pipe 75 and sprayed out through the nozzles. The sprayed aqueous solution can wash the downward side of the square cylinder 29, wash the stains on the square cylinder 29 clean, so that the rough plate on the square cylinder 29 can be kept clean, and avoid the rough plate on the square cylinder 29 being bonded with stains, which may affect the test.

[0056] Specifically, the working principle of this high-level landslide debris flow test model device: When in use, when the slope of the landslide simulation body 2 needs to be adjusted, when the driving motor 523 rotates reversely at a low speed, the ratchet connecting piece 53 on the first rotating shaft 511 does not perform rotational transmission, and the ratchet connecting pieces 53 on the second rotating shaft 512 and the third rotating shaft 513 perform rotational transmission. At this time, the sixth pulley 518 and the third rotating shaft 513 can rotate at a low speed. During the rotation of the sixth pulley 518, the third pulley 37 is driven to rotate through the third transmission belt 38. At this time, the reciprocating lead screw 32 starts to rotate. During the rotation of the reciprocating lead screw 32, the moving block 33 can be driven to move left and right. During the movement of the moving block 33, the rotation angle of the driving arm 36 can be changed, so that the driving arm 36 drives the landslide simulation body 2 to rotate.

[0057] When the slope of the landslide simulation body 2 needs to be adjusted, the driving motor 523 rotates forward. The ratchet connector 53 on the first rotating shaft 511 rotates and drives the transmission. The ratchet connectors 53 on the second rotating shaft 512 and the third rotating shaft 513 do not drive the transmission. At this time, the fifth pulley 517 can rotate. Under the driving action of the second transmission belt 46, the fourth pulley 42 can be driven to rotate. Under the driving action of the first universal joint 43, the second universal joint 45 and the telescopic rod 44, the second pulley 213 can also be driven to rotate. Under the driving action of the first transmission belt 214, the first pulley 211 can be driven to rotate, so that the slope adjustment rotating shaft 27 can rotate, so that the square cylinder 29 rotates between the lower L-shaped plate 21 and the upper L-shaped plate 22, thereby changing the roughness of the slope body.

[0058] After the simulation test is completed, when the driving motor 523 rotates reversely at a high speed, the sixth pulley 518 and the third rotating shaft 513 can rotate at a high speed. During the rotation of the sixth pulley 518, through the transmission of the third transmission belt 38, the slope adjustment driving member 3 drives the moving block 33 to move back and forth along the reciprocating lead screw 32, and the landslide simulation body 2 can be reciprocally lifted and lowered. And at this time, when the pump body drive shaft 54 rotates at a high speed, the suction fan blade 73 can be driven to rotate through the pump body drive shaft 54. During the rotation of the suction fan blade 73, a negative pressure can be formed in the suction pump body 72, so that the aqueous solution in the water tank 6 enters the suction pump body 72 along the water inlet pipe 74, and then is transported outward through the water outlet pipe 75. The aqueous solution is transported to the cleaning pipe 71 through the water outlet pipe 75 and sprayed out through the nozzle. The sprayed aqueous solution can wash the downward side surface of the square cylinder 29, and wash the stains on the square cylinder 29 clean, so that the rough plate on the square cylinder 29 remains clean, and to avoid the rough plate on the square cylinder 29 being bonded with stains, which may affect the test.

[0059] It should be noted that the specific model and specification of the driving motor 523 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.
