[0015] A method for using a syn-sedimentary structure physical simulation experimental device comprises the following steps:

[0016] S1. Place the well-proportioned sediment and debris particles on the deposition platform, inject water into the simulation box and the circulation box, and observe the internal deposition through the external window plate;

[0017] S2, in the initial state, the locking cylinder is retracted, and the driving motor is started to drive the adjusting disk to rotate, and the adjusting disk drives the output disk to rotate, and drives the output shaft to drive the outer water wheel shaft and the output water wheel to rotate, and the output water wheel pushes the internal liquid to flow to both sides, thereby simulating the effect of water flow scouring, and the driving motor controls the forward and reverse rotation of the adjusting disk and the output water wheel. When the output water wheels turn in the same direction, the output water wheels on both sides will drive the installation platform to move forward or backward, thereby changing the position of the waves, and when the output water wheels on both sides turn in opposite directions, they will drive the installation platform to rotate in situ, and the installation platform is placed on the surface of the guide rail base through the top installation column, thereby limiting the movement range and not affecting the rotation and movement, and when there is no need to change the position or angle of the water flow, the locking cylinder descends, driving the locking seat to be locked in the surface of the locking groove and the locking tooth groove, and at this time the angle and position of the installation platform are locked, so as to achieve the effect of simulating water flow scouring at different positions and angles;

[0018] S3. During the rotation of the output water wheel, the adjustment cylinder can be controlled to expand and contract to change the distance between the output disc and the adjustment disc. The output disc can slide on the output shaft, but the inner side will be pushed outward by the ejection spring, while the outer side will be blocked by the adjustment disc. The surface of the adjustment disc is an inclined surface. When the adjustment disc moves, it will be squeezed inward when it is close to the output disc. At this time, the contact point of the output disc on the adjustment disc and the distance to the axis of the adjustment disc will be reduced, which is equivalent to a reduction in the diameter of the meshing point with the output disc, and the transmission ratio between the output disc and the adjustment disc will increase. When it is far away from the output disc, the diameter of the meshing point with the output disc increases, and the transmission ratio decreases. In this way, the speed of the drive motor does not need to change, and the speed of the output disc can be adjusted, thereby controlling the size of the simulated water flow scouring of the output water wheel. When the speeds of the output water wheels on both sides are different, the differential effect will also drive the installation platform to rotate, and the rotation speed is determined by the differential speed, thereby achieving the effect of controlling the rotation speed, movement speed and intensity of the simulated water flow;

[0019] S4. During the rotation of the installation column, the driving cylinder, the pawl turntable and the active pawl at the bottom will be driven to rotate. The active pawl is meshed with the ratchet groove in the pawl turntable to form a ratchet structure, so that the pawl turntable can only rotate in one direction. There are two pairs of active pawls and ratchet grooves in opposite directions, corresponding to the rotation in two directions respectively. The currently meshed active pawl and ratchet groove are controlled by driving the pawl turntable of the cylinder to push and pull the pawl turntable. At the same time, only one pair of active pawls is meshed with the ratchet groove. During the rotation of the pawl turntable, the active worm and the driven worm wheel will be driven to rotate through the connecting sleeve, while it will not work when rotating in the opposite direction. The driven turntable stops to maintain the current state. During the rotation of the driven worm wheel driving the outer rotating disks and the winding column on both sides, since the fixed shaft is fixed, the traction rope will be wrapped around the surface of the fixed shaft, and the inner plates on both sides will be turned inward. Pull and compress the reset spring. When the pawl disc stops rotating, the inner plate will not pull the pawl disc to reverse due to the self-locking effect of the active worm and the driven worm gear. When the inner plate needs to move outward, it is necessary to first switch the rotation direction of the pawl disc by driving the cylinder, and push it to both sides through the action of the reset spring. When the inner plate approaches inward, it will push the liquid in the simulation box inward. At this time, the internal volume decreases and the liquid level rises. When it moves outward, the liquid level decreases, thereby simulating the effect of water level fluctuations. The water inside the simulation box enters the circulation box through the drainage trough, and is input into the simulation box again through the circulation pump and the output pipe. When the inner plate approaches inward, it drives the blocking plate to gradually block the drainage trough. The flow area of ​​the drainage trough is reduced, and the drainage volume is also reduced, thereby simulating the fluctuation of natural water flow and adjusting the water level.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, by adjusting the expansion and contraction of the cylinder through the wave regulating mechanism, the spacing between the output disk and the regulating disk is changed, thereby realizing stepless regulation of the output disk rotation speed. The simulated water flow scouring intensity and speed can be finely adjusted according to experimental requirements through speed control, and the rotation is realized through the differential speed and forward and reverse rotation on both sides, which can better simulate the complex changes of water flow in nature, such as water flow rotation, vortex and other phenomena, and provide precise experimental conditions for studying the sedimentation process under different water flow conditions.

[0022] In the present invention, through the cooperation of the guide rail locking mechanism and the wave regulating mechanism, the effect of water flow can be simulated in the process of conducting physical simulation experiments of the same sedimentary structure, and the speed and direction of the output water wheel can be adjusted to achieve control of the intensity, speed and direction of the water flow. When the speeds of the output water wheels on both sides are different, the installation platform can be driven to rotate to achieve differential control of the water flow, simulate the sedimentation process under more complex water flow conditions, study its influence on sediment transportation and sedimentation morphology, and provide a basis for understanding the formation mechanism of the sedimentary structure. The locking mechanism can lock the position and angle of the installation column, so that the conditions of each experiment are the same, which is convenient for comparing and analyzing different experimental results.

[0023] In the present invention, by cooperating with the water level regulating mechanism and the flow control mechanism, the water level is raised or lowered to simulate the fluctuation of water level and water flow, and the influence of water level change on sediment deposition rate, sedimentation morphology and sedimentation structure is studied, so as to provide more comprehensive information for understanding the formation process of sedimentary structure.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 15 The present invention provides a technical solution: a physical simulation experiment device for a syn-sedimentary structure, comprising a device shell 1, a simulation box 11 is fixedly connected to the inner surface of the device shell 1, a window plate 111 is fixedly connected to the outer surface of the simulation box 11, a deposition platform 112 is fixedly connected to the inner surface of the simulation box 11, a circulation box 2 is fixedly connected to the inner surface of the device shell 1, a mounting column 3 is slidably connected to the inner surface of the simulation box 11, a mounting platform 31 is fixedly connected to the outer surface of the mounting column 3, a guide rail engaging mechanism 4 is arranged on the top surface of the device shell 1, a wave adjustment mechanism 5 is arranged on the top surface of the mounting platform 31, and the outer surface of the wave adjustment mechanism 5 An output water wheel 6 is arranged on the surface, a water level regulating mechanism 7 is arranged on the bottom surface of the mounting column 3, a flow control mechanism 8 is arranged on the inner surface of the simulation box 11, the device housing 1 is used to externally support the simulation box 11 and the circulation box 2, the deposition platform 112 is used to place the silt and debris particles used for the simulation experiment, during the operation of the simulation box 11, the internal deposition situation is observed through the window plate 111, the circulation box 2 and the simulation box 11 are connected through the flow control mechanism 8 for circulating water, the mounting column 3 and the mounting platform 31 are used to install the wave regulating mechanism 5, the output water wheel 6, the water level regulating mechanism 7, and can move and rotate in the simulation box 11 following the mounting column 3.

[0042] The guide rail engaging mechanism 4 includes a guide rail base 41, which is fixedly connected to the inner surface of the device housing 1, and a locking tooth groove 411 is fixedly connected to the top surface of the guide rail base 41. The outer surface of the mounting column 3 is rotatably connected to a follower bracket 42, and the top surface of the follower bracket 42 is fixedly connected to a locking cylinder 421, and the bottom surface of the locking cylinder 421 is fixedly connected to an extrusion spring 422, and the bottom surface of the extrusion spring 422 is fixedly connected to a locking seat 423, and the top surface of the mounting column 3 is fixedly connected to a locking groove 424. Through the setting of the guide rail engaging mechanism 4, during use, the guide rail base 41 supports the mounting column 3 to limit the moving path to only linear movement, but does not affect the rotation in situ, and the follower bracket 42 is rotatably connected to the mounting column 3. Relative rotation can occur between the columns 3, so that when the mounting column 3 rotates, the follower bracket 42 will not rotate synchronously, but will only move with the mounting column 3, so that the locking seat 423 is always at the same height as the mounting column 3, and the locking cylinder 421 first presses down the extrusion spring 422 and pushes the locking seat 423. Since the extrusion spring 422 can be compressed, the locking seat 423 will not be completely pressed down by the locking cylinder 421. This is because when the locking seat 423 is pressed down, it sometimes does not just fit into the locking tooth groove 411 and the locking groove 424, and will move or rotate a distance with the mounting column 3 until the locking seat 423 is aligned with the locking tooth groove 411 and the locking groove 424. At this time, under the action of the extrusion spring 422, it is pressed down and clamped to fix the position of the mounting column 3.

[0043] There are two guide rail bases 41, and the two guide rail bases 41 are symmetrically distributed with the central axis of the device housing 1 as the symmetry axis. The mounting column 3 is slidably connected to the top surface of the guide rail base 41, the output end of the engaging cylinder 421 passes through the inner surface of the engaging seat 423, and the output end of the engaging cylinder 421 is slidably connected to the inner surface of the engaging seat 423, the engaging seat 423 is slidably connected to the engaging groove 424 and the engaging tooth groove 411, and the symmetrical guide rail base 41 supports both sides of the mounting column 3.

[0044] The wave regulating mechanism 5 includes a fixed base 51, which is fixedly connected to the top surface of the mounting platform 31, an output disk 511 is rotatably connected to the inner surface of the fixed base 51, an ejection spring 512 is slidably connected to the outer surface of the output disk 511, a limiting rod 513 is fixedly connected to the outer surface of the fixed base 51, an output shaft 52 is rotatably connected to the inner surface of the fixed base 51, a locking protrusion 521 is provided on the outer surface of the output shaft 52, one end of the output shaft 52 is fixedly connected to the water wheel shaft 522, an adjusting cylinder 53 is fixedly connected to the outer surface of the fixed base 51, an output end of the adjusting cylinder 53 is fixedly connected to a lifting base 54, an adjusting disk 541 is rotatably connected to the inner surface of the lifting base 54, a driving motor 542 is fixedly connected to the outer surface of the lifting base 54, and a limiting slot 543 is fixedly connected to the outer surface of the lifting base 54. Through the setting of the wave regulating mechanism 5, during use, two groups of wave regulating mechanisms 5 are respectively installed The two sides of the mounting platform 31 are used to respectively control the output water wheels 6 on both sides. The output disk 511 and the adjusting disk 541 fit tightly and have a certain friction. When the adjusting disk 541 rotates, the output disk 511 will be driven to rotate, which is equivalent to a pair of gears. The position of friction is the pitch circle size. The position of friction of the output disk 511 remains unchanged. The adjusting disk 541 will move closer to the inner side as the friction position decreases. The closer the output disk 511 moves inward, the closer the friction position is to the axis of the adjusting disk 541, which is equivalent to a decrease in the pitch circle radius of the adjusting disk 541, while the rotation speed of the adjusting disk 541 remains unchanged. The transmission ratio between the adjusting disk 541 and the output disk 511 increases, and the output disk 511 slows down, and vice versa, it speeds up, thereby steplessly adjusting the rotation speed of the output disk 511. The output disk 511 can slide on the output shaft 52, but cannot rotate relatively due to the action of the engaging protrusion 521. The rotation of the output disk 511 will drive the output shaft 52 to rotate, and the rotation is finally output to the water wheel shaft 522 and the output water wheel 6.

[0045] There are two fixed bases 51, and the two fixed bases 51 are symmetrically distributed with the central axis of the mounting platform 31 as the axis of symmetry. There are two output disks 511 in each fixed base 51, and the two output disks 511 are symmetrically distributed with the central axis of the fixed base 51 as the axis of symmetry. The output shaft 52 and the engaging protrusion 521 pass through the output disk 511 and are slidably connected to the inner wall thereof. The ejection spring 512 is sleeved on the outer surface of the output shaft 52. The output end of the driving motor 542 passes through the inner surface of the lifting base 54, and the output end of the driving motor 542 is rotatably connected to the inner surface of the lifting base 54.

[0046] The water level regulating mechanism 7 includes a connecting shell 71, which is rotatably connected to the outer surface of the mounting column 3, and a driven rotating disk 711 is rotatably connected to the inner surface of the connecting shell 71. A ratchet groove 712 is provided on the inner surface of the driven rotating disk 711. A driving cylinder 72 is fixedly connected to the bottom surface of the mounting column 3, and a pawl rotating disk 721 is fixedly connected to the output end of the driving cylinder 72. The outer surface of the pawl rotating disk 721 is rotatably connected to the active pawl 722. A connecting sleeve 73 is fixedly connected to the bottom surface of the driven rotating disk 711, and a driving worm 74 is fixedly connected to the bottom surface of the connecting sleeve 73. A driven worm gear 741 is meshed with the outer surface of the active worm gear 74, and both ends of the driven worm gear 741 are fixedly connected to an outer rotating disk 742.

The driven turntable 711 on the connecting shell 71 can only rotate under the drive of the mounting post 3 and the pawl turntable 721, and the rotation direction is controlled by the ratchet groove 712 and the active pawl 722. The ratchet groove 712 and the active pawl 722 are switched by driving the cylinder 72 to realize forward and reverse rotation, and the inner side plates 77 on both sides are pulled to control the water level. When the top is engaged, if the mounting post 3 rotates counterclockwise at this time, the active pawl 722 pushes the driven turntable 711 to rotate, and the traction rope 76 is wound up under the action of the active worm 74 and the driven worm wheel 741. The inner side plate 77 is pulled inward and compresses the reset spring 782 to rise the water level. When the water level rises to the required level, When the required height is reached, the active ratchet 722 is pressed into the ratchet rotating disk 721 when it is rotated clockwise, which will not drive the driven rotating disk 711 to rotate, and the inner side plate 77 will not be pulled. Although the return spring 782 will pull the inner side plate 77 outward, when passing through the active worm 74 and the driven worm gear 741, the active worm 74 cannot be driven by the driven worm gear 741 due to the self-locking effect of the worm and worm gear, so the position of the inner side plate 77 is fixed. At this time, the mounting column 3 can be rotated clockwise to adjust the angle of the output water wheel 6 while the water level is maintained. When the water level needs to be lowered, the driving cylinder 72 drives the ratchet groove 712 at the bottom to engage with the active ratchet 722. At this time, clockwise rotation is useless, and counterclockwise rotation will gradually release the traction rope 76 from the fixed shaft 75.Under the action of the reset spring 782, the inner plate 77 is reset and the water level drops.

[0047] There are two ratchet grooves 712 on the driven rotating disk 711, and the directions of the two ratchet grooves 712 are opposite. There are two ratchet rotating disks 721 on the output end of the driving cylinder 72. There are two active ratchets 722, and the directions of the two active ratchets 722 are opposite. The ratchet grooves 712 are meshed with the active ratchets 722. The driven worm gear 741 is rotatably connected with the fixed shaft 75. The traction rope 76 passes through the fixed shaft 75, and the traction rope 76 is wound around the outer surface of the fixed shaft 75. There are two inner plates 77, and the two inner plates 77 are symmetrically distributed with the central axis of the simulation box 11 as the symmetry axis. The sliding traction seat 761 is slidably connected with the inner surface of the traction sliding groove 771, and the spring mounting rod 781 passes through the inner plate 77, there are two spring mounting rods 781 on each inner plate 77, and the two spring mounting rods 781 are symmetrically distributed with the central axis of the inner plate 77 as the axis of symmetry, the spring mounting rod 781 is fixedly connected to the inner surface of the simulation box 11, the upper and lower ratchet grooves 712 and the active pawl 722 respectively control the forward and reverse rotation, the mounting column 3 will move, the sliding traction seat 761 at the other end of the fixed traction rope 76 can slide in the traction sliding groove 771 on the inner plate 77 to adapt to different positions, the inner plate 77 can slide on the spring mounting rod 781 and install the reset spring 782, and the sealing gasket 78 is installed at the connection between the inner plate 77 and the spring mounting rod 781 to prevent water from flowing out of the connection when moving inward to raise the water level.

[0048] The flow control mechanism 8 includes a drainage groove 81, which is opened on the inner surface of the simulation box 11, and the bottom surface of the drainage groove 81 is fixedly connected to the connection box 811, and the inner surface of the connection box 811 is fixedly connected to the guide plate 812, and the outer surface of the guide plate 812 is provided with a drainage hole 813, and the inner surface of the drainage groove 81 is slidably connected to the blocking plate 82, and the inner surface of the blocking plate 82 is fixedly connected to the output pipe 83, and the other end of the output pipe 83 is fixedly connected to the circulation pump 831. Through the setting of the flow control mechanism 8, it is linked with the water level regulating mechanism 7. When the water level rises, the water discharge is reduced to control the water flow and maintain a high water level. The water slides through the guide plate 812 on the connection box 811 to the drainage hole 813 and is output to the circulation box 2 for water circulation.

[0049] The drainage groove 81 passes through the simulation box 11, the connection box 811 is fixedly connected to the inner surface of the simulation box 11, the bottom surface of the connection box 811 is fixedly connected to the circulation box 2, the drainage hole 813 passes through the drainage plate 812, the blocking plate 82 is fixedly connected to the inner plate 77, the circulation pump 831 is fixedly connected to the outer surface of the circulation box 2, and the input end of the circulation pump 831 passes through the inner surface of the circulation box 2.

[0050] In this embodiment, Figure 1 , Figure 2 As shown, the device housing 1 is used to externally support the simulation box 11 and the circulation box 2, and the deposition platform 112 is used to place the sediment and debris particles used for the simulation experiment. During the operation of the simulation box 11, the internal deposition situation is observed through the window plate 111;

[0051] In this embodiment, Figure 3 As shown, the mounting column 3 and the mounting platform 31 are used to install the wave regulating mechanism 5, the output water wheel 6, and the water level regulating mechanism 7, and can move and rotate in the simulation box 11 following the mounting column 3;

[0052] In this embodiment, Figure 4 As shown, the follower bracket 42 is rotatably connected to the mounting column 3 and can rotate relative to each other. When the mounting column 3 rotates, the follower bracket 42 will not rotate synchronously, but will only move with the mounting column 3. After the engaging seat 423 is pressed down by the engaging cylinder 421 and the extrusion spring 422, the engaging seat 423 is aligned with the engaging tooth groove 411 and the engaging groove 424 and is engaged.

[0053] In this embodiment, Figure 5 As shown, two sets of wave regulating mechanisms 5 are respectively installed on both sides of the mounting platform 31, and are used to control the output water wheels 6 on both sides respectively;

[0054] In this embodiment, Figure 6 , Figure 7 , Figure 8 As shown, the adjustment cylinder 53 is controlled to expand and contract to change the distance between the output disk 511 and the adjustment disk 541. The friction position of the output disk 511 remains unchanged, and the adjustment disk 541 moves closer to the inner side as the friction position decreases. As the output disk 511 moves closer to the inner side, the friction position moves closer to the axis of the adjustment disk 541, which is equivalent to a reduction in the pitch circle radius of the adjustment disk 541, while the rotation speed of the adjustment disk 541 remains unchanged, and the transmission ratio between the adjustment disk 541 and the output disk 511 increases, and the output disk 511 decelerates.

[0055] In this embodiment, Fig. 9 , Fig.10 As shown, the driven turntable 711 on the connecting housing 71 can only rotate under the drive of the mounting column 3 and the pawl turntable 721. The ratchet groove 712 and the active pawl 722 are switched to achieve forward and reverse rotation by driving the cylinder 72 to push and pull the pawl turntable 721. Under the action of the active worm 74 and the driven worm wheel 741, the traction rope 76 is retracted and released, and the inner plate 77 is pulled to control the water level rise and fall;

[0056] In this embodiment, Fig.11 As shown, the active pawls 722 and the ratchet grooves 712 are provided in two pairs and in opposite directions, corresponding to the rotation in two directions respectively;

[0057] In this embodiment, Fig.12 As shown, the driven worm gear 741 drives the outer rotating disks 742 and the winding posts 7421 on both sides to rotate, and the traction rope 76 is wound around the surface of the fixed shaft 75 .

[0058] In this embodiment, Fig.13 , Fig.14 , Fig.15 As shown, the circulation box 2 and the simulation box 11 are connected via a flow control mechanism 8 for circulating water. When the inner plate 77 approaches inward, it drives the blocking plate 82 to gradually block the drainage groove 81. The flow area of ​​the drainage groove 81 is reduced, and the drainage volume is also reduced.

[0059] A method for using a syn-sedimentary structure physical simulation experimental device comprises the following steps:

[0060] S1, placing the well-proportioned sediment and debris particles on the deposition platform 112, injecting water into the simulation box 11 and the circulation box 2, and observing the internal deposition through the external window plate 111;

[0061] S2. In the initial state, the engaging cylinder 421 is retracted. At this time, the driving motor 542 is started to drive the adjusting disk 541 to rotate. The adjusting disk 541 drives the output disk 511 to rotate, and drives the output shaft 52 to drive the outer water wheel shaft 522 and the output water wheel 6 to rotate. The output water wheel 6 pushes the internal liquid to flow to both sides, thereby simulating the effect of water flow flushing. The driving motor 542 controls the forward and reverse rotation of the adjusting disk 541 and the output water wheel 6. When the output water wheels 6 turn in the same direction, the output water wheels 6 on both sides will drive the installation platform 31 to move forward or backward , thereby changing the position of the waves, and when the output water wheels 6 on both sides turn in opposite directions, the mounting platform 31 will be driven to rotate in situ, and the mounting platform 31 is placed on the surface of the guide rail base 41 through the mounting column 3 on the top, thereby limiting the movement range without affecting the rotation and movement, and when there is no need to change the position or angle of the water flow, the engaging cylinder 421 descends, driving the engaging seat 423 to be engaged in the surface of the engaging groove 424 and the engaging tooth groove 411, at this time, the angle and position of the mounting platform 31 are locked, realizing the effect of simulating the flushing of water flow at different positions and angles;

[0062] S3. During the rotation of the output water wheel 6, the adjusting cylinder 53 can be controlled to expand and contract to change the distance between the output disk 511 and the adjusting disk 541. The output disk 511 can slide on the output shaft 52, but the inner side will be pushed outward by the ejection spring 512, while the outer side will be blocked by the adjusting disk 541. The surface of the adjusting disk 541 is an inclined surface. When the adjusting disk 541 moves, it will be squeezed inward when it is close to the output disk 511. At this time, the contact point of the output disk 511 on the adjusting disk 541 and the distance to the axis of the adjusting disk 541 will be reduced, which is equivalent to meshing with the output disk 511. When the diameter of the meshing part decreases, the transmission ratio between the output disc 511 and the adjusting disc 541 increases. When the output disc 511 is far away, the diameter of the meshing part with the output disc 511 increases, and the transmission ratio decreases. In this way, the speed of the output disc 511 can be adjusted without changing the speed of the driving motor 542, thereby controlling the size of the simulated water flow scouring by the output water wheel 6. When the speeds of the output water wheels 6 on both sides are different, the differential effect will also drive the mounting platform 31 to rotate, and the rotation speed is determined by the differential speed, thereby achieving the effect of controlling the rotation speed, movement speed and intensity of the simulated water flow;

[0063] S4, during the rotation of the mounting column 3, the driving cylinder 72, the pawl turntable 721 and the active pawl 722 at the bottom will be driven to rotate, and the active pawl 722 will mesh with the ratchet groove 712 in the pawl turntable 721 to form a ratchet structure, so that the pawl turntable 721 can only rotate in one direction. The active pawl 722 and the ratchet groove 712 are provided with two pairs in opposite directions, corresponding to the rotation in two directions respectively. The driving cylinder 72 pushes and pulls the pawl turntable 721 to control the currently engaged active pawl 722 and the ratchet groove 712, only one pair of active pawls 722 are engaged with the ratchet groove 712 at the same time, and the pawl rotating disk 721 will drive the active worm 74 and the driven worm wheel 741 to rotate through the connecting sleeve 73 during the rotation of the pawl rotating disk 721, and it will not work when rotating in the reverse direction, and the driven rotating disk 711 will stop rotating to maintain the current state, and the driven worm wheel 741 will drive the outer rotating disks 742 and the winding column 7421 on both sides to rotate, and since the fixed shaft 75 is fixed, the traction rope 76 will be wound around the surface of the fixed shaft 75 When the inner plate 77 moves inward, the inner plates 77 on both sides are pulled inward and the return springs 782 are compressed. When the pawl turntable 721 stops rotating, the inner plate 77 will not pull the pawl turntable 721 to reverse due to the self-locking effect of the active worm 74 and the driven worm gear 741. When the inner plate 77 needs to move outward, the rotation direction of the pawl turntable 721 needs to be switched by the driving cylinder 72 first, and the return springs 782 are used to push it to both sides. When the inner plate 77 moves inward, the liquid in the simulation box 11 is pushed inward. At this time, the internal volume decreases and the liquid level rises. When moving outward, the liquid level decreases, thereby simulating the effect of the rise and fall of the water level. The water inside the simulation box 11 enters the circulation box 2 through the drainage groove 81, and is input into the simulation box 11 again through the circulation pump 831 and the output pipe 83. When the inner plate 77 approaches inward, it drives the blocking plate 82 to gradually block the drainage groove 81. The flow area of ​​the drainage groove 81 is reduced, and the drainage volume is also reduced, thereby simulating the rise and fall of natural water flow and adjusting the water level height.

In the initial state, the engagement cylinder (421) is retracted. At this time, the drive motor (542) is started to drive the adjustment disk (541) to rotate. The adjustment disk (541) drives the output disk (511) to rotate, and drives the output shaft (52) to drive the outer water wheel shaft (522) and the output water wheel (6) to rotate. The output water wheel (6) pushes the internal liquid to flow to both sides, thereby simulating the effect of water flow flushing. The drive motor (542) controls the forward and reverse rotation of the adjustment disk (541) and the output water wheel (6). When the output water wheel (6) turns in the same direction, the output water wheels (6) on both sides will drive the installation platform (31) forward. or moves backward, thereby changing the position of the waves, and when the output water wheels (6) on both sides turn in opposite directions, the mounting platform (31) is driven to rotate in situ, and the mounting platform (31) is placed on the surface of the guide rail base (41) through the mounting column (3) at the top, thereby limiting the range of movement without affecting the rotation and movement, and when there is no need to change the position or angle of the water flow, the engaging cylinder (421) descends, driving the engaging seat (423) to engage in the surface of the engaging groove (424) and the engaging tooth groove (411), and at this time the angle and position of the mounting platform (31) are locked, thereby achieving the effect of simulating the flushing of water flow at different positions and angles; S3. During the rotation of the output water wheel (6), the adjusting cylinder (53) can be controlled to extend and retract to change the distance between the output disk (511) and the adjusting disk (541). The output disk (511) can slide on the output shaft (52), but the inner side will be pushed outward by the ejection spring (512), while the outer side will be blocked by the adjusting disk (541). The surface of the adjusting disk (541) is an inclined surface. When the adjusting disk (541) moves, it will be squeezed inward when it approaches the output disk (511). At this time, the contact point of the output disk (511) on the adjusting disk (541) and the axis center of the adjusting disk (541) will be reduced, which is equivalent to the contact point with the output disk (511). The diameter of the meshing point (511) is reduced, and the transmission ratio between the output disc (511) and the adjusting disc (541) is increased. When the output disc (511) is far away from the output disc (511), the diameter of the meshing point with the output disc (511) is increased, and the transmission ratio is reduced. In this way, the rotation speed of the output disc (511) can be adjusted without changing the rotation speed of the driving motor (542), thereby controlling the size of the simulated water flow scouring of the output water wheel (6). When the rotation speeds of the output water wheels (6) on both sides are different, a differential effect is achieved, which will also drive the mounting platform (31) to rotate, and the rotation speed is determined by the differential speed, thereby achieving the effect of controlling the rotation speed, movement speed and intensity of the simulated water flow; S4. During the rotation of the mounting column (3), the driving cylinder (72), the pawl rotating disk (721) and the active pawl (722) at the bottom are driven to rotate. The active pawl (722) is meshed with the ratchet groove (712) in the ratchet rotating disk (721) to form a ratchet structure, so that the ratchet rotating disk (721) can only rotate in one direction. Two pairs of active pawls (722) and the ratchet groove (712) are arranged in opposite directions, corresponding to the rotation in two directions respectively. The currently meshed active pawl is controlled by pushing and pulling the ratchet rotating disk (721) through the driving cylinder (72). (722) and the ratchet groove (712), only one pair of active ratchets (722) is meshed with the ratchet groove (712) at the same time, and the ratchet rotating disk (721) will drive the active worm (74) and the driven worm wheel (741) to rotate through the connecting sleeve (73) during rotation, and will not work when rotating in the reverse direction, and the driven rotating disk (711) will stop rotating to maintain the current state, and the driven worm wheel (741) will drive the outer rotating disks (742) and the winding column (7421) on both sides to rotate. Since the fixed shaft (75) is fixed, the traction rope (76) will be wound around the fixed shaft (75). The inner plates (77) on both sides are pulled inward and the return springs (782) are compressed. When the ratchet turntable (721) stops rotating, the inner plates (77) will not pull the ratchet turntable (721) to reverse due to the self-locking effect of the active worm (74) and the driven worm gear (741). When the inner plates (77) need to move outward, the rotation direction of the ratchet turntable (721) needs to be switched by the driving cylinder (72) and the return springs (782) are used to push the ratchet turntable (721) to both sides. When the inner plates (77) move inward, the liquid in the simulation box (11) is pushed outward. When the inner plate (77) moves inward, the internal volume decreases and the liquid level rises. When the inner plate (77) moves outward, the liquid level decreases, thereby simulating the effect of the rise and fall of the water level. The water inside the simulation box (11) enters the circulation box (2) through the drainage groove (81) and is input into the simulation box (11) again through the circulation pump (831) and the output pipe (83). When the inner plate (77) moves inward, the blocking plate (82) is driven to gradually block the drainage groove (81). The runoff area of ​​the drainage groove (81) is reduced, and the drainage volume is also reduced, so as to simulate the rise and fall of natural water flow and adjust the water level.
