Description

[0002] With the rapid development of infrastructure construction, a large number of engineering activities involve slope engineering, such as road construction, water conservancy projects, mining, etc. In these projects, the stability of the slope is crucial, because slope instability may cause geological disasters such as landslides and collapses, posing a serious threat to the safety of life and property, and will also cause huge economic losses and environmental damage.

[0003] However, most of the existing slope sliding test devices use fixed nozzles for spraying. The nozzles are usually installed on the top of the test box or at a specific position, and spray water downward at a certain angle to simulate the scouring effect of rainfall on the slope model. As a result, it is difficult to simulate the scouring effect of rain on the slope under different rainfall intensities and wind directions. At the same time, it is difficult for the existing slope sliding test device to simulate the vibration test and the spray test at the same time, so the experimental results are relatively simple, or in the process of simulating the vibration test and the spray test, two independent driving mechanisms are usually required, which increases the cost of the experiment and reduces the efficiency of the experiment.

Specifically, in the slope sliding test, the servo motor 201 is first started according to the longitudinal spraying angle required by the spraying test mechanism 3. At this time, the servo motor 201 drives the first rotating rod 202 and the first bevel gear 203 to rotate.Then, in the process of the first bevel gear 203 and the second bevel gear 207 being meshed, the first short rod 206 drives the sealing rotating plate 205 to rotate, and at this time, the clamping seat 208 drives the clamping block 210 to rotate synchronously, and at this time, the clamping block 210 drives the sealing circular plate 209 and the limit block 214 to rotate, and at the same time, the limit block 214 drives the limit sleeve 213, the positioning circular plate 211, the second short rod 216 and the third bevel gear 217 to rotate, and at this time, in the process of the third bevel gear 217 and the fourth bevel gear 219 being meshed, the one-way screw rod 218 is rotated, so that the one-way slider 31 8 drives the assembly block 319, the transmission rod 320, the first intermediate gear cylinder 321 and the second intermediate gear cylinder 322 to move horizontally, thereby achieving the purpose of adjusting the spray angle of the spray test mechanism 3.

Specifically, in the slope sliding test, the servo motor 201 is first started according to the longitudinal spraying angle required by the spray test mechanism 3, and the one-way screw rod 218 is rotated during the meshing process of the third bevel gear 217 and the fourth bevel gear 219, so that the one-way slider 318 drives the assembly block 319, the transmission rod 320, the first intermediate gear cylinder 321 and the second intermediate gear cylinder 322 to move laterally.During the lateral movement of the first middle gear cylinder 321, it will first mesh with the first adjusting tooth plate 316, thereby causing the first middle gear cylinder 321 to drive the transmission rod 320 and the second middle gear cylinder 322 to rotate. At this time, the second middle gear cylinder 322 will mesh with the middle gear plate 315 on one side and cause the middle gear plate 315 to drive the gear rack 312 to move horizontally. At this time, during the lateral movement of the gear rack 312, it will mesh with the driven gear cylinder 309 and cause the driven gear cylinder 309 to rotate.

The gear rack 312 is meshed with the middle gear plate 315 on the other side, so that the middle gear plate 315 drives the gear rack 312 to move in the opposite direction, and the driven gear cylinder 309 drives the adjustment plate 304 and the spray nozzle 305 to tilt to another position, thereby achieving the purpose of multi-angle adjustment of the position of the adjustment plate 304 and the spray nozzle 305, effectively simulating the angle of rainwater spraying on the slope surface in the slope sliding test, and improving the accuracy of the experiment. Among them, by starting the servo motor 201 to adjust the spray angle of the spray test mechanism 3, the vibration test mechanism 4 drives the second model 403 to vibrate. First, the spraying of the spray test mechanism 3 is accurately controlled by the servo motor 201 Angle, can simulate the scouring effect of rain on the slope under different rainfall intensity and wind direction conditions, so as to make the experiment closer to the actual situation of slope sliding, and effectively improve the accuracy of the experiment. Second, the vibration test mechanism 4 is vibrated by the servo motor 201, which simulates the situation of slope sliding under earthquake conditions, thereby improving the diversity of slope sliding simulation experiments. Third, it can simulate the experimental results under different spraying angles and vibration combinations, which is helpful to improve the accuracy of slope sliding experiments. Fourth, when the spraying test mechanism 3 adjusts the spraying angle, water is directly supplied to the spraying test mechanism 3 through the water pump 224, so that the block 210 is not connected with the holder 208, so that the servo motor 201 drives the vibration test mechanism 4 to vibrate without affecting the spraying test mechanism 3.The experimental steps are seamlessly connected, making the experimental operation more convenient and efficient. Fifth, the driving mechanism of the spraying experiment mechanism 3 when adjusting the spraying angle is simplified, and the water supply process of the water pump 224 is used to separate the spraying experiment mechanism 3 and the vibration experiment mechanism 4. Then the vibration experiment can be carried out quickly, reducing the pause and adjustment time during the experiment and improving the experimental efficiency.

[0035] like Fig.13 and Fig.14 The vibration experiment mechanism 4 includes a vibration seat 401, a first placement groove 103 is provided at the front end of the upper surface of the experiment box 102, the vibration seat 401 is arranged inside the first placement groove 103, the four corners of the lower surface of the vibration seat 401 are fixedly connected with vibration legs 402, the upper surface of the vibration seat 401 is fixedly connected with a second model 403, the middle part of the first placement groove 103 is rotatably connected with a second rotating rod 405, the outer wall of the middle part of the second rotating rod 405 is fixedly connected with a cam 406, and the outer walls on both sides of the first rotating rod 202 and the second rotating rod 405 are fixedly connected with transmission wheels 407 The outer wall of the transmission wheel 407 is provided with a toothed belt 408, and the middle part of the outer wall of the vibration seat 401 is fixedly connected with a dust collecting cover 404. Specifically, during the rotation of the first rotating rod 202, the second rotating rod 405 will rotate under the action of the transmission wheel 407 and the toothed belt 408, and the second rotating rod 405 will drive the cam 406 to rotate. At this time, the cam 406 in the rotating process will cause the vibration seat 401 to drive the second model 403 to rotate, thereby simulating the process of slope sliding under earthquake conditions, increasing the diversity of experiments, and effectively simulating slope sliding experiments under different conditions.

[0036] Specifically, the working principle of the slope slip test device is as follows: in the slope slip test, the servo motor 201 is first started according to the longitudinal spray angle required by the spray test mechanism 3. At this time, the servo motor 201 drives the first rotating rod 202 and the first bevel gear 203 to rotate, and then in the process of the first bevel gear 203 and the second bevel gear 207 meshing, the first short rod 206 drives the sealing rotating plate 205 to rotate. At this time, the clamping seat 208 drives the clamping block 210 to rotate synchronously. At this time, the clamping block 210 will drive the sealing circular plate 209 and the limit block 214 to rotate. At the same time, the limit block 214 drives the limit sleeve 213, the positioning circular plate 211, the second short rod 216 and the third bevel gear 217 to rotate. At this time, the third bevel gear 217 and the fourth bevel gear During the engagement of the one-way screw rod 219, the one-way slider 318 is rotated, so that the one-way slider 318 drives the assembly block 319, the transmission rod 320, the first intermediate gear cylinder 321 and the second intermediate gear cylinder 322 to move laterally. During the lateral movement of the first intermediate gear cylinder 321, it will first engage with the first adjusting tooth plate 316, so that the first intermediate gear cylinder 321 drives the transmission rod 320 and the second intermediate gear cylinder 322 to rotate. At this time, the second intermediate gear cylinder 322 will engage with the one side intermediate gear plate 315 and make the intermediate gear plate 315 drive the gear rack 312 to move laterally. At this time, during the lateral movement of the gear rack 312, it will engage with the driven gear cylinder 309 and make the driven gear cylinder 309 rotate. At this time, the driven gear cylinder 309 during the rotation will drive the adjusting plate 316 to rotate. 04 rotates synchronously, thereby causing the adjustment plate 304 and the spray nozzle 305 to tilt toward one position, effectively simulating the angle of rain falling. When necessary, when the adjustment plate 304 and the spray nozzle 305 tilt toward the opposite position, the servo motor 201 continues to rotate, and the first intermediate gear cylinder 321 passes through the first adjustment gear plate 316 during the movement. At this time, the first adjustment gear plate 316 will not be able to limit the rotation direction of the transmission rod 320, and the second intermediate gear cylinder 322 will not be able to limit the position of the intermediate gear plate 315 on one side. At this time, under the action of the long reset spring 313, the gear rack 312 will drive the intermediate gear plate 315 back to its original position, and the intermediate gear plate 315 will mesh with the second intermediate gear cylinder 322 and cause the transmission rod 320 to rotate in the opposite direction and return to its original position. When the gear rack 312 is meshed with the driven gear cylinder 309, the adjustment plate 304 and the spray nozzle 305 will return to their original positions. During the continuous lateral movement of the assembly block 319, the first intermediate gear cylinder 321 will mesh with the second adjustment gear plate 317 and cause the transmission rod 320 to rotate in the opposite direction. At this time, the second intermediate gear cylinder 322 will mesh with the intermediate gear plate 315 on the other side, causing the intermediate gear plate 315 to drive the gear rack 312 to move in the opposite direction, and causing the driven gear cylinder 309 to drive the adjustment plate 304 and the spray nozzle 305 to tilt to another position, thereby achieving the purpose of multi-angle adjustment of the position of the adjustment plate 304 and the spray nozzle 305, effectively simulating the angle of rainwater spraying on the slope surface in the slope sliding test, and improving the accuracy of the experiment.After the positions of the adjusting plate 304 and the spray nozzle 305 are determined, the servo motor 201 is stopped first, and then the water pump 224 is started to work. At this time, the water pump 224 will absorb water from the inside of the water storage box 223 through the second connecting pipe 225, and then supply water to the inside of the intermediate cylinder 204 through the third connecting pipe 226. At this time, the water pressure inside the lower end of the intermediate cylinder 204 will increase and lift the sealing circular plate 209, and the sealing circular plate 209 will drive the clamping block 210 to move upward. At this time, the clamping block 210 will no longer be engaged with the clamping seat 208. At the same time, the sealing circular plate 209 drives the limit block 214 to move upward, and the limit block 214 moves inside the limit sleeve 213. The reset short spring 215 will be compressed. At the same time, in the process of the sealing circular plate 209 moving upward, the water inside the intermediate cylinder 204 will flow into the inside of the water collecting box 221 through the first connecting pipe 222. At this time, it will flow to the The inside of the transfer box 306 then supplies liquid to the inside of the adjustment plate 304 through the connecting short thin tube 307, and sprays the liquid to the surface of the first model 302 through the spray nozzle 305. At this time, the servo motor 201 is started again to make the first rotating rod 202 rotate again. Since the block 210 is not mutually engaged with the clamping seat 208, the first short rod 206 drives the sealing rotating plate 205 and the clamping seat 208 to rotate idly, and the second short rod 216 cannot continue to rotate. At this time, during the rotation of the first rotating rod 202, the second rotating rod 405 will rotate under the action of the transmission wheel 407 and the toothed belt 408, and the second rotating rod 405 drives the cam 406 to rotate. At this time, the cam 406 in the rotating process will cause the vibration seat 401 to drive the second model 403 to rotate, thereby simulating the process of slope sliding under earthquake conditions, increasing the diversity of experiments, and effectively simulating slope sliding experiments under different conditions.
