[0038] Initially, the torsional spring 32 is in a twisted state, when using the device, sequentially pull out the first sealing plug 25 one by one, then fill the experimental soil of different soil quality into the first storage tank 241, the second storage tank 242 respectively, and put the first sealing plug 25 into the original position, then fill water into the glass tank 11, stop filling water when the water surface reaches the required height, then arrange high-speed cameras, high-definition cameras, PIV particle imagers and the like at the corresponding positions outside the glass tank 11, and connect them with the data acquisition system, then control the first motor 13 to drive the test piece 12 to rotate upward to the required angle for experiment, so as to drive the first guide piece 21 to deflect left, so that the first storage tank 241, the second storage tank 242 are lifted.

[0039] When it is needed to experiment on the first soil quality, the second motor 22 can be controlled to drive the first screw 23 to rotate forward, so as to drive the first blocking piece 24 to move upward, the first blocking piece 24 no longer blocks the left side opening of the first storage tank 241, the soil quality in the first storage tank 241 will flow out from the opening to the isolation cloth 3, the high-speed cameras, the high-definition cameras, the PIV particle imagers and the like can collect experimental data of the first soil quality, after collection is completed, the third motor 34 can be controlled to drive the rotating cylinder 31 on the left side to rotate, the water pump 16 to pump water, the rotating cylinder 31 on the left side will wind the isolation cloth 3, so as to drive the rotating cylinder 31 on the right side to rotate and release the isolation cloth 3, the rotating cylinder 31 on the left side will also drive the missing gear 35 to rotate.

[0040] When the rotating cogwheel 35 is no longer engaged with the spur gear 33, the second blocking piece 36 will be flipped down under the action of the torsion spring 32, the rectangular discharge hole of the test piece 12 is opened, at this time the first experimental soil on the isolation cloth 3 will slide into the clay collection box 14 from the rectangular discharge hole, with the water in the glass box 11 being discharged from the water outlet pipe 15, under the action of the water flow, the experimental soil on the isolation cloth 3 will be completely flushed into the clay collection box 14, when the rotating cogwheel 35 is engaged with the spur gear 33, the cogwheel 35 drives the second blocking piece 36 to flip up and reset through the spur gear 33, 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 the second soil needs to be tested, first, the water pump 16 is turned off, then the glass box 11 is filled with water to the required height, and then the first screw rod 23 is driven to rotate forward by the second motor 22, at this time the first blocking piece 24 moving upward will hook the first storage box 241, and the first storage box 241 will also move upward, and the first storage box 241 will be separated from the isolation cloth 3 and no longer be supported by the test piece 12, and the first spring 26 will be deformed, the first storage box 241 moving upward no longer blocks the left opening of the second storage box 242, and the second soil will flow out from the left opening of the second storage box 242 to the isolation cloth 3, and data can be collected through a high-speed camera.

[0042] According to the above steps, after the data is collected, the third motor 34 is controlled to rotate the rotating cylinder 31 to replace the isolation cloth 3, and then the water is drained and filled again, and the same operation is repeated, when the third soil needs to be tested, the first screw rod 23 is driven to rotate forward by the second motor 22, so that the left second storage box 242 also moves upward, and the left second storage box 242 is separated from the isolation cloth 3 and no longer supported by the test piece 12, and the first spring 26 will also be deformed, the second storage box 242 moving upward no longer blocks the opening of the right second storage box 242, and the third soil will flow out from the left opening of the right second storage box 242 to the isolation cloth 3, and the experimental data is recorded again, and the same operation can be performed when there is a fourth soil.

[0043] When all kinds of soil experiments are completed, the second motor 22 drives the first screw 23 to rotate reversely, so that the first blocking piece 24 moves downward to reset, and under the elastic action of the first spring 26, the second storage tank 242 on the left and the first storage tank 241 gradually fall to contact the isolation cloth 3 and are supported by the test piece 12, and then the first motor 13 drives the test piece 12 to rotate downward to reset.

In addition, the missing gear 35, the straight gear 33, the second blocking piece 36 and the isolation cloth 3 cooperate to quickly clean the experimental soil, maintain the cleanliness and preparation state of the device, and the whole experimental process is simple and clear, convenient to operate, reduces the labor intensity of the experimental personnel, 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] Example 2: Based on example 1, as shown in Figure 10 、 Figure 11 and Figure 12 , it further includes a pre-laying mechanism for laying test soil on the isolation cloth 3, the pre-laying mechanism is arranged on the first blocking piece 24, and the pre-laying mechanism includes a first fixed piece 4 fixedly connected to the top of the first blocking piece 24, a second fixed piece 41 fixedly connected to the top of the first storage tank 241, and a second sealing plug 44 for controlling the opening and closing of the leakage hole is slidably connected to the bottom wall of each of the two second storage tanks 242.

The first fixed piece 4 and the second fixed piece 41 are respectively pressed on the adjacent sliding pieces 42.

[0045] Initially, the leakage hole at the bottom of the first storage tank 241 is open, and the leakage holes of the remaining second storage tanks 242 are all sealed by the adjacent second sealing plugs 44, and the first fixed piece 4 and the second fixed piece 41 are both pressed on the adjacent sliding pieces 42, and the second springs 43 are all in a deformed state. When the first storage tank 241 is filled with experimental soil, the first type of experimental soil will first leak out onto the isolation cloth 3, thereby laying a corresponding soil layer on the bottom wall of the test piece 12. When the first blocking piece 24 moves upward, the first blocking piece 24 drives the first fixed piece 4 to move upward, and under the elastic action of the second spring 43, the sliding piece 42 in the left second storage tank 242 drives the second sealing plug 44 to move upward, and the leakage hole of the left second storage tank 242 is opened.

[0046] According to the foregoing steps, when the isolation cloth 3 is replaced, the first storage box 241 no longer blocks the left side opening of the left second storage box 242, a portion of the second experimental soil in the left second storage box 242 will leak out of the leakage hole to the new isolation cloth 3 for paving, at the same time, as the first blocking piece 24 hooks the first storage box 241 and continues to move upward, the second fixed piece 41 is driven to move upward, and under the elastic action of the right second spring 43, the sliding piece 42 in the right second storage box 242 drives the second sealing plug 44 to move upward, and the leakage hole of the right second storage box 242 is also opened, when the left second storage box 242 moves upward to be separated from the isolation cloth 3, the third experimental soil in the right second storage box 242 will leak out of the leakage hole to the new isolation cloth 3.

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

[0048] As shown in Figure 13 and Figure 14 , it also includes a push-out mechanism for removing the clay collection box 14 from the glass box 11 when the experiment is completed.

A pushing piece 54 is slidably connected between the two second guide pieces 55. The pushing piece 54 is connected with the two second guide pieces 55 through the third spring 56. The two third springs 56 are wound on the pushing piece 54. The rear second guide piece 55 is fixedly connected with a guide frame 57. The guide frame 57 is rotatably connected with the pushing piece 54 through the second screw rod 53. The second screw rod 53 is connected with the adjacent rotating cylinder 31 through a transmission assembly.

[0049] As shown in Figure 13 , the transmission assembly includes a transmission wheel 5. The rear part of the left rotating cylinder 31 is fixedly connected with the transmission wheel 5. The threaded sleeve 52 is rotatably connected with the guide frame 57. The transmission wheel 5 and the threaded sleeve 52 are wound with a belt 51. The threaded sleeve 52 is threadedly connected with the second screw rod 53.

[0050] As shown in Figure 13 , it also includes a fixed cylinder 5301. The rear left part of the glass box 11 is fixedly connected with the fixed cylinder 5301. The second screw rod 53 slides in the fixed cylinder 5301.

[0051] At the beginning, the third spring 56 is in the deformed state, when the third motor 34 drives the left rotating cylinder 31 to rotate, the left rotating cylinder 31 also drives the transmission wheel 5 to rotate, and then drives the threaded sleeve 52 to rotate through the belt 51, so as to drive the second screw 53 to move backward into the fixed cylinder 5301, with three rotations of the left rotating cylinder 31, at this time, the three kinds of soil have been tested, and the second screw 53 will gradually move backward to separate from the pushing piece 54, under the elastic force of the third spring 56, the pushing piece 54 is pushed out to the left, the pushing piece 54 pushed out to the left will push the clay collecting box 14 out of the glass box 11, so as to facilitate the staff to clean the clay collecting box 14.

[0052] After cleaning, first push the clay collecting box 14 into the original position, so as to drive the pushing piece 54 to move right to the original position, the third spring 56 returns to the deformed state, then control the third motor 34 to drive the left rotating cylinder 31 to rotate counterclockwise, so as to drive the second screw 53 to move forward to reset to be inserted into the pushing piece 54, in summary, the position of the second screw 53 is controlled by the transmission assembly, so that after the three kinds of soil are tested, the clay collecting box 14 can be automatically pushed out for cleaning, thereby improving the work efficiency.
