Description

Technical Field

[0001] The invention relates to the technical field of indoor experiments for simulating ocean landslides, and in particular to an indoor experimental device for simulating ocean landslides. Background Art

[0002] Submarine landslides are one of the key sedimentary processes that transport sediments from the shelf slope break zone to the deep-sea basin, and have an important impact on the seabed topography and sediment distribution. Even when the terrain slope is very small, the debris flow formed by the submarine landslide can slide at high speed to hundreds of kilometers due to the "water sliding" effect, seriously threatening the safety of marine oil and gas development platforms, oil and gas pipelines, submarine cables and other facilities. Therefore, simulated marine landslides play an important role in disaster prevention and control, engineering safety, scientific research development and teaching improvement.

[0003] For example, the patent with the authorization publication number CN207764186U and the announcement date of 2018-08-24 discloses a test device for simulating submarine landslides, including a model box, a glass surface on the model box for convenient observation of the internal situation of the model box, a tilted slideway arranged in the model box, the lower end of the slideway can be rotatably connected to a support plate, the support plate is fixed to the model box, the upper end of the slideway is connected to the model box via a slideway inclination adjustment mechanism, the upper surface of the slideway is covered with a cushion layer, a mud flow generating mechanism for releasing mud is provided above the upper part of the slideway, and a monitoring mechanism for monitoring the state of mud on the slideway is provided corresponding to the slideway. However, the above scheme still has certain shortcomings in actual use. For example, during use, the mud storage box can only store a single soil type, while in actual submarine landslide research, the landslide body may be composed of a variety of different soil types, and the simulation of a single soil type cannot fully reflect the actual situation, thereby limiting the flexibility of the test. The slideway surface needs to be cleaned after each test, which increases the complexity of the operation and reduces the detection efficiency.

A first material storage box 241 and two second material storage boxes 242 are placed, and the left sides of the first material storage box 241 and the second material storage box 242 are both in an open shape, and the right wall of the first material storage box 241 blocks the left opening of the adjacent second material storage box 242, and the first sealing plug 25 is clamped on the top wall of the first material storage box 241 and the second material storage box 242, and the first material storage box 241 is slidably connected with the first blocking member 24 on the left side, the first screw 23 is threadedly connected to the front part of the first blocking member 24, and the first guide member 21 is slidably connected to the rear part of the first blocking member 24, and the first material storage box 241 and the adjacent second material storage box 242 are connected with symmetrically distributed first springs 26, and the adjacent second material storage boxes 242 are also connected with symmetrically distributed first springs 26, and the bottoms of the first material storage box 241 and the two second material storage boxes 242 are provided with leakage holes.

[0036] like Figure 3 As shown, the drainage assembly includes a water outlet pipe 15 . A drainage hole is opened at the bottom of the glass box 11 . The water outlet pipe 15 is fixed to the bottom of the glass box 11 . The water outlet pipe 15 is aligned with the drainage hole. A water pump 16 is installed on the water outlet pipe 15 .

[0037] like Figure 7 , Figure 8 and Fig. 9As shown, it also includes a cleaning mechanism for cleaning the test soil poured on the test piece 12, the cleaning mechanism is arranged on the test piece 12, and the cleaning mechanism includes a rotating cylinder 31, the left and right sides of the bottom wall of the test piece 12 are rotatably connected with the rotating cylinder 31, and an isolation cloth 3 is wound on the rotating cylinder 31 on the right side, and the movable end of the isolation cloth 3 is laid flat on the bottom wall of the test piece 12 and wound on the rotating cylinder 31 on the left side, and the isolation cloth 3 passes through the bottom of the first storage box 241, the second storage box 242 and the test piece 12, and a rectangular discharge hole is opened on the left side of the bottom wall of the test piece 12. The left side of the bottom is rotatably connected with a second blocking member 36 for controlling the opening and closing of the rectangular discharge hole. A symmetrically distributed torsion spring 32 is connected between the second blocking member 36 and the test piece 12. Both torsion springs 32 are wound around the second blocking member 36. A third motor 34 is installed on the left side of the rear side of the test piece 12. The output shaft on the front side of the third motor 34 is fixedly connected with a rotating shaft 3401 through a coupling. The rotating shaft 3401 is rotatably connected with the rear wall of the test piece 12. The missing gear 35 is fixedly connected to the rotating shaft 3401. A spur gear 33 is fixedly connected to the rear side of the second blocking member 36. The spur gear 33 meshes with the missing gear 35.

[0038] Initially, the torsion spring 32 is in a twisted state. When the device is used, the first sealing plugs 25 are pulled out one by one in turn, and then the experimental soils of different soil qualities are filled in the first storage box 241 and the second storage box 242 respectively, and the first sealing plugs 25 are all stuffed into their original positions, and then water is poured into the glass box 11. When the water level reaches the required height for the experiment, the water filling is stopped, and then high-speed cameras, high-definition cameras, PIV particle imagers, etc. are arranged at corresponding positions outside the glass box 11, and connected to the data acquisition system, and then the first motor 13 is controlled to drive the test piece 12 to rotate upward to the required angle for the experiment, thereby driving the first guide member 21 to deflect to the left, so that the first storage box 241 and the second storage box 242 are lifted.

[0039] When it is necessary to experiment on the first type of soil, the second motor 22 can be controlled to drive the first screw 23 to rotate forward, thereby driving the first blocking member 24 to move upward, and the first blocking member 24 no longer blocks the left opening of the first storage box 241. The soil in the first storage box 241 will flow out from the opening onto the isolation cloth 3. High-speed cameras, high-definition cameras, PIV particle imagers, etc. can collect experimental data of the first type of soil. After the collection is completed, the third motor 34 can be controlled to drive the rotating drum 31 on the left to rotate and the water pump 16 to pump water. The rotating drum 31 on the left will reel in the isolation cloth 3, thereby driving the rotating drum 31 on the right to rotate and release the isolation cloth 3. The rotating drum 31 on the left will also drive the missing gear 35 to rotate.

[0040] When the rotating missing gear 35 is no longer engaged with the spur gear 33, under the action of the torsion spring 32, the second blocking member 36 will flip downward, and the rectangular discharge hole of the test piece 12 will be opened. At this time, the first type of experimental soil on the isolation cloth 3 will slide into the clay collection box 14 from the rectangular discharge hole. As the water in the glass box 11 is discharged from the outlet pipe 15, under the action of the water flow, the experimental soil on the isolation cloth 3 will all be flushed into the clay collection box 14. When the rotating missing gear 35 is engaged with the spur gear 33, the missing gear 35 drives the second blocking member 36 to flip upward and reset through the spur gear 33, and the torsion spring 32 returns to the torsion state. At this time, the third motor 34 stops rotating, and the isolation cloth 3 laid on the bottom wall of the test piece 12 has also been replaced.

[0041] When it is necessary to experiment on the second type of soil, first turn off the water pump 16, then fill the glass box 11 with water to the required height for the experiment, and then continue to control the second motor 22 to drive the first screw 23 to rotate forward. At this time, the first blocking member 24 that continues to move upward will hook the first storage box 241, and the first storage box 241 will also move upward. The first storage box 241 will be separated from the isolation cloth 3 until it is no longer supported by the test piece 12, and the adjacent first spring 26 will be deformed. The first storage box 241 that moves upward will no longer block the left opening of the adjacent second storage box 242, and the second type of soil will flow out from the left opening of the second storage box 242 onto the isolation cloth 3, and data can continue to be collected through a high-speed camera.

[0042] According to the previous steps, after the data is collected, the third motor 34 is controlled to drive the rotating cylinder 31 to rotate so that the isolation cloth 3 is replaced, and the water is drained and filled again. By analogy, when it is necessary to experiment on the third type of soil, the second motor 22 is controlled to drive the first screw 23 to continue to rotate forward, so that the second storage box 242 on the left also moves upward, and the second storage box 242 on the left will be separated from the isolation cloth 3 and no longer supported by the test piece 12. The adjacent first spring 26 will also be deformed, and the second storage box 242 moving upward will no longer block the opening of the second storage box 242 on the right. The third type of soil will flow out from the left opening of the second storage box 242 on the right to the isolation cloth 3, and the experimental data will be recorded again. By the same token, the same operation can be performed when there is a fourth type of soil.

[0043] When all experiments on all types of soil are completed, the second motor 22 is first controlled to drive the first screw 23 to rotate in the opposite direction, thereby driving the first blocking member 24 to move downward and reset. At the same time, under the elastic action of the first spring 26, the second storage box 242 and the first storage box 241 on the left will gradually fall until they are in contact with the isolation cloth 3 and supported by the test piece 12, and then the first motor 13 is controlled to drive the test piece 12 to rotate downward and reset. In summary, by setting up multiple storage boxes to store different types of experimental soil, it is convenient to switch between different soils for experiments to meet diverse research needs, and then through the cooperation of the missing gear 35, the spur gear 33, the second blocking member 36, and the isolation cloth 3, the gushing experimental soil can be quickly cleaned up to keep the device clean and ready. The whole experimental process is simple and clear, easy to operate, reduces the labor intensity of the experimenters, solves the shortcomings of the existing device in soil storage and cleaning, improves the efficiency and accuracy of the experiment, and provides a more convenient and efficient experimental means for the field of marine engineering research.

[0044] Embodiment 2: Based on embodiment 1, Fig.10 , Fig.11 and Fig.12 As shown, it also includes a pre-laying mechanism for laying test soil on the isolation cloth 3, the pre-laying mechanism is arranged on the first blocking member 24, the pre-laying mechanism includes a first fixing member 4, the first fixing member 4 is fixedly connected to the top of the first blocking member 24, the second fixing member 41 is fixedly connected to the top of the first storage box 241, the bottom walls of the two second storage boxes 242 are slidably connected with second sealing plugs 44 for controlling the opening and closing of the leakage holes, the tops of the two second sealing plugs 44 are fixedly connected with symmetrically distributed sliding members 42, the symmetrically distributed sliding members 42 are slidably connected to the adjacent second storage boxes 242, second springs 43 are connected between the symmetrically distributed sliding members 42 and the adjacent second storage boxes 242, the symmetrically distributed second springs 43 are all wound around the adjacent sliding members 42, the first fixing member 4 and the second fixing member 41 are respectively pressed on the adjacent sliding members 42.

[0045] Initially, the leakage hole at the bottom of the first material storage box 241 is open, while the leakage holes of the remaining second material storage boxes 242 are sealed by the adjacent second sealing plugs 44. The first fixing member 4 and the second fixing member 41 are both pressed on the adjacent sliding member 42, and the second springs 43 are both in a deformed state. When the first material storage box 241 is filled with experimental soil, the first experimental soil will first leak out of the leakage hole onto the isolation cloth 3, so as to lay a corresponding soil layer on the bottom wall of the test piece 12. When the first blocking member 24 moves upward, the first blocking member 24 will drive the first fixing member 4 to move upward. Under the elastic action of the second spring 43, the sliding member 42 in the left second material storage box 242 will drive the second sealing plug 44 to move upward, and the leakage hole of the left second material storage box 242 will be opened.

[0046] It can be known from the previous steps that when the isolation cloth 3 is replaced and the first storage box 241 no longer blocks the left opening of the left second storage box 242, a part of the second experimental soil in the left second storage box 242 will leak out from the leakage hole to be laid on the new isolation cloth 3. At the same time, as the first blocking member 24 hooks the first storage box 241 and continues to move upward, the second fixing member 41 is driven to move upward. Under the elastic action of the right second spring 43, the sliding member 42 in the right second storage box 242 will drive the second sealing plug 44 to move upward, and the leakage hole of the right second storage box 242 will also be opened. When the left second storage box 242 moves upward to be separated from the isolation cloth 3, the third type of experimental soil in the right second storage box 242 will leak out from the leakage hole to the new isolation cloth 3.

[0047] When the second storage box 242 on the left and the first storage box 241 gradually fall down to contact with the isolation cloth 3 and are supported by the test piece 12, the first fixing member 4 and the second fixing member 41 are both pressed on the adjacent sliding member 42, and the second spring 43 returns to the deformed state. In summary, through the cooperation of the first blocking member 24, the first fixing member 4, the second fixing member 41, the sliding member 42, and the second sealing plug 44, when switching between different soil types for experiments, the soil layer can be cleaned and the new soil layer can be laid quickly, thereby improving the efficiency and accuracy of the experiment.

[0048] like Fig.13 and Fig.14 As shown, it also includes a push-out mechanism for moving the clay collection box 14 out of the glass box 11 when the experiment is completed. The push-out mechanism is arranged on the glass box 11, and includes a second guide member 55. The left parts of the front and rear inner walls of the glass box 11 are fixedly connected with the second guide members 55. A pushing member 54 is slidably connected between the two second guide members 55. A third spring 56 is connected between the pushing member 54 and the two second guide members 55. The two third springs 56 are both wound around the pushing member 54. A guide frame 57 is fixedly connected to the second guide member 55 on the rear side. A second screw 53 is rotatably connected between the guide frame 57 and the pushing member 54. A transmission assembly is connected between the second screw 53 and the adjacent rotating cylinder 31.

[0049] like Fig.13 As shown, the transmission assembly includes a transmission wheel 5, the transmission wheel 5 is fixedly connected to the rear of the left rotating cylinder 31, the threaded sleeve 52 is rotatably connected to the guide frame 57, a belt 51 is wound around the transmission wheel 5 and the threaded sleeve 52, and the threaded sleeve 52 is threadedly connected to the second screw 53.

[0050] like Fig.13 As shown, a fixing cylinder 5301 is also included. The fixing cylinder 5301 is fixedly connected to the left rear portion of the glass box 11 , and the second screw rod 53 slides in the fixing cylinder 5301 .

[0051] Initially, the third spring 56 is in a deformed state. When the third motor 34 drives the rotating cylinder 31 on the left to rotate, the rotating cylinder 31 on the left will also drive the transmission wheel 5 to rotate, and then drive the threaded sleeve 52 to rotate through the belt 51, thereby driving the second screw 53 to move backward to enter the fixed cylinder 5301. As the rotating cylinder 31 on the left rotates three times, the three types of soil have been tested at this time, and the second screw 53 will gradually move backward to separate from the pushing member 54. Under the elastic force of the third spring 56, the pushing member 54 pops out to the left, and the pushing member 54 that pops out to the left will push the clay collection box 14 out of the glass box 11, making it easier for the staff to clean the clay collection box 14.

[0052] After cleaning, the clay collection box 14 is first pushed into its original position, thereby driving the pusher 54 to move rightward to its original position, and the third spring 56 returns to its deformed state, and then the third motor 34 is controlled to drive the rotating cylinder 31 on the left to rotate counterclockwise, thereby driving the second screw 53 to move forward and reset to the inserted pusher 54. In summary, the position of the second screw 53 is controlled by the transmission assembly, so that after the experiments on the three types of soil are completed, the clay collection box 14 can be automatically pushed out for easy cleaning, thereby improving work efficiency.
