[0002] The experimental device for simulating the scouring and silting environment of the dock slope is mainly used to study and simulate the interaction between water flow and dock slope, especially the scouring, deposition and slope erosion process under different hydrological conditions. This type of device provides a necessary experimental platform for environmental protection, slope design and optimization of dock engineering, and can help researchers accurately analyze the long-term impact of water flow on the slope.

[0019] The present invention provides a test device for simulating the scouring and silting environment of a dock slope. It has the following beneficial effects:

[0020] 1. The present invention can drive the paddle to move downward by utilizing a driving mechanism, and a driving motor can drive the paddle to rotate, thereby accelerating the flow rate of water. The water can be diverted and the flow direction of the water flow can be adjusted by utilizing a diversion mechanism, thereby accurately simulating the scouring and deposition process of different water flow sizes, and can also simulate the erosion effect of different water flow angles on the bank slope, thereby enhancing the accuracy of the experimental results.

Therefore, it can realize water recycling while achieving water cleaning, effectively avoiding the accumulation of silt in the water and the pollution of the experimental environment.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0035] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments.

[0036] Please see attached Figure 1-Figure 10The embodiment of the present invention provides a test device for simulating the scouring and silting environment of a dock bank slope, comprising: a box body 1, a partition 101 is installed inside the box body 1, which is used to divide the internal space of the box body 1, and an opening 102 is provided on one side of the partition 101, which is used to connect the divided space; a bank slope model 17, which is installed on the top surface of the partition 101; a driving mechanism 2, which is located at the top of the box body 1 and is used to drive the motor 3 to move, and the motor 3 is used to drive the paddle 4 to rotate to move the water flow; a diversion mechanism 5, which is installed in the middle of the top of the box body 1 and is used to guide the water flow to flow to and impact the bank slope model 17.

[0037] In this embodiment, the dock slope is simulated by using the slope model 17. When the water flow hits the slope model 17, an experiment simulating the scouring and silting environment of the dock slope can be carried out. In the experiment, the driving mechanism 2 is used to drive the motor 3 and the paddle 4 to approach the support plate 201, and then the motor 3 is driven to drive the paddle 4 to rotate. At this time, the paddle 4 can stir the water flow to accelerate its flow, and the diversion mechanism 5 can also be used to guide the flow direction of the water flow, thereby accurately simulating the scouring and deposition process of different water flow sizes, and can also simulate the erosion effect of different water flow angles on the slope, thereby enhancing the accuracy of the experimental results, and a waterproof cover is provided on the outside of the motor 3 to prevent water from contacting the motor 3.

[0038] Please see attached Figure 2 and Figure 5 The driving mechanism 2 includes a support plate 201, which is fixedly connected to one side of the top surface of the box body 1. An electric push rod 202 is installed in the middle of the top surface of the support plate 201. The output end of the electric push rod 202 is fixedly connected to a bracket 203. The motor 13 is fixedly connected to one side of the bracket 203, and the paddle 4 is rotatably connected to the middle of the bracket 203. A guide rod 204 is fixedly connected to the outer side of the middle part of the top surface of the bracket 203, and the guide rod 204 is slidably connected to the support plate 201. A guide rail 205 is fixedly connected to the side wall of the top of the box body 1. A guide groove 206 is opened on the outer wall of the bracket 203, and the inner wall of the guide groove 206 is slidably connected to the outer wall of the guide rail 205.

[0039] In this embodiment, the electric push rod 202 is driven to extend the output end to push out the bracket 203, and then the bracket 203 drives the motor 3 and the paddle 4 to move downward, so that the paddle 4 can contact with water, and in the process of the bracket 203 moving downward, the guide rod 204 can be used to guide the movement direction of the bracket 203, and the guide groove 206 and the guide rail 205 can be used to further guide the bracket 203, thereby improving the stability of the operation of the bracket 203.

[0040] Please see attached Figure 1 , Figure 2 , Figure 6 and Figure 7The flow guide mechanism 5 includes a horizontal plate 501, a base 502 and a flow guide plate 503. The horizontal plate 501 is fixedly connected to the middle of the top surface of the box body 1. The base 502 is fixedly connected to the middle of the top surface of the partition 101. A clamping rod 504 is fixedly connected to one side of the inner bottom of the flow guide plate 503. The clamping rod 504 is arranged inside the base 502. A pull rod 505 is fixedly connected to one side of the top surface of the flow guide plate 503. The middle part of the outer wall of the pull rod 505 is slidably connected to the horizontal plate 501. A spring 1 506 is sleeved on the middle and lower part of the outer wall of the pull rod 505. A plurality of clamping blocks 507 are fixedly connected to the outer wall of the clamping rod 504. A plurality of clamping slots 508 are opened inside the base 502. The clamping blocks 507 are located inside the clamping slots 508.

[0041] In this embodiment, pulling the pull rod 505 drives the guide plate 503 and the clamping rod 504 to move upward. At this time, the clamping rod 504 moves out from the inside of the base 502. Turning the pull rod 505 drives the guide plate 503 to rotate along the pull rod 505 as the rotation axis. When the pull rod 505 is released, the clamping rod 504 will be inserted into the base 502, and the clamping block 507 will be engaged in the clamping groove 508. At this time, the angle between the guide plate 503 and the cross plate 501 can be adjusted, thereby adjusting the flow direction of the water flow. There are multiple guide plates 503, and each guide plate 503 can be adjusted individually. Therefore, multiple water flows can be generated and each water flow moves in a different direction, thereby completing the simulation of complex water flows.

[0042] Please see attached Figure 1 and Figure 2 A water pump 6 is fixedly connected to one side of the bottom of the box body 1, the input end of the water pump 6 is connected to the inner bottom of the box body 1, the output end of the water pump 6 is connected to the inner top side of the box body 1 through a delivery pipe 7, and a slope 8 is fixedly connected to one side of the inner bottom of the box body 1.

[0043] In this embodiment, the water at the bottom of the box body 1 can be pumped out by the water pump 6 and then discharged. After being discharged, the water flow will impact the slope 8, and after being guided by the slope 8, it can enter the partition 101 and flow along the top surface of the partition 101.

[0044] Please see attached Figure 1 , Figure 2 , Figure 8 and Fig. 9A feeding mechanism 9 is arranged just above the slope 8, and the feeding mechanism 9 includes a material box 903, and the material box 903 is fixedly connected to the inner top of the box body 1, and a motor 2 901 is fixedly connected to the top of one side of the material box 903, and an eccentric wheel 902 is fixedly connected to the output end of the motor 2 901, and scrapers 904 are arranged on both sides of the material box 903, and through holes 905 are opened in the scrapers 904 and the material box 903, and the through holes 905 of the material box 903 and the scrapers 904 are arranged on the inner sides of the material box 903. 05 are staggered with each other, the adjacent sides of the top surfaces of the scrapers 904 on both sides are fixedly connected with support arms 906, the top surfaces of the adjacent sides of the support arms 906 on both sides are respectively in contact with the two sides of the outer wall of the eccentric wheel 902, the tops of the distant sides of the support arms 906 on both sides are fixedly connected with sliding rods 908, the outer wall of the sliding rods 908 is provided with springs 909, the middle part of the top surface of the material box 903 is fixedly connected with a cover shell 907, and the sliding rods 908 on both sides are respectively slidably connected with the two sides of the cover shell 907.

[0045] In this embodiment, the driving motor 901 drives the eccentric wheel 902 to rotate. When the long diameter side of the eccentric wheel 902 contacts the support arm 906, the eccentric wheel 902 squeezes the support arms 906 and the scrapers 904 on both sides away from each other. At this time, the through holes 905 on the material box 903 and the scrapers 904 are connected to each other, and the spring 909 is in a compressed state. When the short diameter side of the eccentric wheel 902 contacts the support arm 906, the spring 909 squeezes the support arms 906 on both sides to drive the scrapers 904 on both sides to approach each other, thereby realizing the reciprocating swing of the scrapers 904, and then the mud and sand in the material box 903 can be indirectly entered into the water. At this time, the water flow can carry the mud and sand to impact the slope model 17, and the swing of the support arm 906 will also turn over the mud and sand in the material box 903, thereby avoiding the blockage of mud and sand.

[0046] Please see attached Figure 2 and Figure 4 A clamping strip 19 is fixedly connected to one side of the middle portion of the top surface of the partition 101 , and a mounting groove 18 is provided on the bottom surface of the slope model 17 , and the clamping strip 19 is located inside the mounting groove 18 .

[0047] In this embodiment, the bank slope model 17 can be engaged by using the clamping strip 19. Therefore, when installing the bank slope model 17, the bank slope model 17 is first placed on the partition 101, and the clamping strip 19 is aligned with the installation groove 18, and then the bank slope model 17 is moved so that the left side of the clamping strip 19 is engaged with the left side inside the installation groove 18. When the bank slope model 17 needs to be replaced, the bank slope model 17 is first pushed toward the guide plate 503, and then the bank slope model 17 can be lifted up to be removed, thereby making the loading and unloading of the bank slope model 17 convenient.

[0048] Please see attached Figure 1 , Figure 2 , Figure 3 and Fig.10Guide plates 10 are fixedly connected to both sides of the top side wall of the box body 1, and the bottom surfaces of the guide plates 10 on both sides are fixedly connected to the top surface of the partition 101. A partition plate 11 is fixedly connected to the side of the bottom surface of the partition 101 close to the opening 102, a side plate 2 13 is fixedly connected to the middle of one side of the partition plate 11, an inclined plate 14 is fixedly connected to the middle and lower part of one side of the partition plate 11, a side plate 12 is arranged just above the inclined plate 14, and the top surface of the side plate 12 is fixedly connected to the bottom surface of the partition 101, a baffle 15 is arranged at the bottom of one side of the outer wall of the box body 1 close to the opening 102, the baffle 15 is connected to the box body 1 by bolts, and a filter screen 16 is installed on the inner top of the isolation plate 11.

[0049] In this embodiment, the water flow can be guided by the guide plate 10, and the flow path of the water flow can be restricted by the guide plate 10 so that it all passes under the paddle 4, thereby avoiding the phenomenon that the paddle 4 cannot move the water flow, and when the water flow carries mud and sand to hit the slope model 17, it then passes through the gap between the slope model 17 and the box body 1 to enter the right side of the box body 1, and then passes through the opening 102 to enter the inner bottom of the box body 1, and then the water flow hits the lower side of the inclined plate 14, at which time the mud and sand can be initially gathered, and the water can be filtered again through the filter screen 16 to avoid the mud and sand in the water from re-entering the water pump 6 with the water, and after removing the bolts, the baffle 15 can be removed, and at this time the mud and sand accumulated on the lower side of the inclined plate 14 can be cleaned, thereby achieving the cleaning of the inside of the box body 1.

[0050] Working principle: When in use, first add water to the inside of the box 1, and finally let the water enter the inner bottom of the box 1, then place the bank slope model 17 on the partition 101, and align the clamping strip 19 with the installation groove 18, then move the bank slope model 17, so that the left side of the clamping strip 19 is clamped on the left side of the installation groove 18, and finally place the mud and sand in the material box 903, waiting for the test;

[0051] During the test, the water pump 6 is driven first to pump out the water at the bottom of the box body 1 and let it enter the top of the box body 1. After the water is ejected, it will first hit the slope 8, then be guided by the slope 8, then be guided by the guide plate 10 and the guide plate 503, then hit the bank slope model 17, and finally enter the bottom of the box body 1 along the opening 102;

[0052] And in the experiment, the eccentric wheel 902 is driven to rotate by driving the second motor 901. When the long diameter side of the eccentric wheel 902 contacts the support arm 906, the eccentric wheel 902 will squeeze the support arms 906 on both sides to make them move away from each other, thereby driving the scrapers 904 on both sides to move away from each other. At this time, the through holes 905 on the material box 903 and the scraper 904 will be in a connected state, and the second spring 909 will be in a compressed state. When the short diameter side of the eccentric wheel 902 contacts the support arm 906, the second spring 909 will squeeze the support arms 906 on both sides to drive the scrapers 904 on both sides to move closer to each other, so that the scraper 904 can swing back and forth, and then the sediment in the material box 903 can be made to enter the water. At this time, the water flow can carry the sediment to impact the slope model 17, and the swing of the support arm 906 will also turn over the sediment in the material box 903.

[0053] At the same time, by driving the electric push rod 202 to extend the output end, the bracket 203 can be pushed out, and then the bracket 203 will drive the motor 13 and the paddle 4 to move downward. When the paddle 4 contacts the water flow, the motor 13 is driven to drive the paddle 4 to rotate. At this time, the paddle 4 can move the water flow, thereby accelerating the flow rate of the water flow, and indirectly rotate the motor 13. At this time, the paddle 4 can be used to indirectly beat the water flow, so as to realize the water flow advancing in a wave-like manner, thereby simulating the situation of beating the dock;

[0054] The pull rod 505 is then pulled to drive the guide plate 503 and the clamping rod 504 to move upward, and the clamping rod 504 can be moved out of the base 502. The pull rod 505 is then rotated to drive the guide plate 503 to rotate along the pull rod 505 as the rotation axis. At this time, the spring 1 506 is in a compressed state. When the pull rod 505 is released, the clamping rod 504 is inserted into the base 502, and the clamping block 507 is engaged in the clamping groove 508, thereby preventing the clamping rod 504 and the base 502 from rotating relative to each other. At this time, the angle between the guide plate 503 and the cross plate 501 can be adjusted to adjust the flow direction of the water flow. A plurality of guide plates 503 are provided, and each guide plate 503 can be adjusted individually. Therefore, multiple water flows can be generated, and each water flow moves in a different direction, thereby completing the simulation of complex water flows.

[0055] When the water flow carries the silt and hits the bank slope model 17, the silt will accumulate on the side of the bank slope model 17 close to the guide plate 503. Therefore, by setting the box body 1 to be a colorless and transparent material, the accumulation of silt around the bank slope model 17 can be visually observed. At the same time, a ruler can be installed on the partition 101. The thickness of the silt accumulation can be accurately obtained by the ruler. After the accumulated silt is taken out, the soil density and water content of the silt can be measured. At the same time, the excess water and silt will enter the right side of the box body 1 through the gap between the bank slope model 17 and the box body 1, and then enter through the opening 102. The inner bottom of the box body 1, and when the water flow carries the silt and falls, it will impact the lower side of the inclined plate 14, and as the liquid level gradually rises, the water flow will contact the bottom of the side plate 12, and then overflow and contact the bottom surface of the side plate 2 13, and finally overflow and enter the side of the box body 1 near the water pump 6 through the filter 16. Since the inclined plate 14 is in an inclined state, the silt carried in the water will accumulate on the lower side of the inclined plate 14, and the silt can be initially gathered at this time, and the water can be filtered again through the filter 16 to prevent the silt in the water from re-entering the water pump 6 with the water;

[0056] When the accumulated sand needs to be cleaned, the bolts are removed, and then the baffle 15 is removed. At this time, the sand accumulated on the lower side of the inclined plate 14 can be cleaned, thereby cleaning the inside of the box body 1.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
