Description

Technical Field

[0001] The invention relates to the technical field of sedimentation simulation experimental devices, and in particular to a quantitative sedimentation physical simulation experimental water tank device. Background Art

[0002] Sedimentation simulation is an important experimental means and technical method for theoretical research in sedimentology, which can be divided into numerical simulation and physical simulation. Physical simulation is a reservoir description and prediction technology developed based on hydrodynamics, sedimentology and reservoir geology. By simulating the sedimentation conditions at the time, the deposition process of natural sediments is restored in the laboratory. The required experimental equipment includes a water pool, a bottom plate system, a detection system, a sand adding system, etc., among which the bottom plate system is one of the most critical devices. At present, the existing bottom plate systems at home and abroad are divided into two categories: fixed bottom plates and movable bottom plates. Fixed bottom plates are low in cost, but cannot meet the needs of complex bottom shapes; movable bottom plates can not only be used repeatedly, but also have a wider range of application scenarios, but the cost is higher and the control is more complex.

[0003] The movable floor of the CNPC Lake Basin Sedimentation Simulation Laboratory at Yangtze University is made up of four square steel floors connected by rubber. Each floor is controlled by four screw lifts to tilt in different directions to simulate various sedimentary bottom shapes. However, the rubber joints are prone to deformation, mud and sand are prone to collapse, and are prone to leaking from the sides of the rubber. Based on this, Chinese patent specification CN109991377A discloses a detachable sedimentation simulation movable floor device and sedimentation simulation floor system, which includes an active lifting and translation mechanism, a passive lifting and translation mechanism, and a connecting assembly. The active lifting and translation mechanism is connected to the passive lifting and translation mechanism through the connecting assembly, and the active lifting and translation mechanism is slidably connected to the connecting assembly, and the passive lift is hinged to the connecting assembly. The connecting assembly solves the problem of poor rubber connection effect.

[0004] The above-mentioned detachable deposition simulation movable base plate device and the shielding plate of the deposition simulation base plate system can only change the inclination angle, which results in the same slope length of the uplift, depression and other bottom shapes simulated by the deposition simulation base plate system, which seriously limits the types of bottom shapes that can be simulated by the deposition simulation base plate system. It cannot simulate the complex bottom shape types in real scenes, and the application scenarios are relatively limited. Summary of the Invention

[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0025] like Figure 1 、 Figure 2 and Figure 5 As shown, the present invention provides a quantitative sedimentation physics simulation experiment water tank device, including a fixed bottom plate unit 10, a bridge unit 20 and a movable bottom plate unit 30, wherein the fixed bottom plate unit 10 includes a pillar 11 and a fixed bottom plate 12 horizontally arranged on the pillar 11, the bridge unit 20 includes a telescopic plate assembly 21, the telescopic plate assembly 21 includes a plate body 211 hinged to the fixed bottom plate 12 and a sliding plate 212 capable of telescopic movement relative to the plate body 211, the movable bottom plate unit 30 includes a movable bottom plate 31 and a lifting mechanism 32 connected to the movable bottom plate 31 by transmission, and the movable bottom plate 31 has an upper surface. Multiple groups of connecting parts 33 are provided at intervals on the surface, and the sliding plate 212 is detachably rotatably connected to one group of the connecting parts 33. The lifting mechanism 32 is used to lift the movable bottom plate 31. When the movable bottom plate 31 is lifted or lowered, the sliding plate 212 can be telescopically moved relative to the plate body 211 to adjust the slope length and slope of the telescopic plate assembly 21. The sliding plate 212 can be switched and connected with multiple groups of connecting parts 33. When the sliding plate 212 is switched and connected with multiple groups of connecting parts 33, the sliding plate 212 can be telescopically moved relative to the plate body 211 to adjust the slope length and slope of the telescopic plate assembly 21.

[0026] When the quantitative sedimentation physics simulation experiment water tank device of the present invention is conducting a simulation experiment, since the sliding plate 212 of the telescopic plate assembly 21 can telescopically move relative to the plate body 211, and the sliding plate 212 is detachably rotatably connected to one set of connection parts 33 in the multiple sets of connection parts 33, when the lifting mechanism 32 drives the movable bottom plate 31 to descend, the sliding plate 212 can slide a distance relative to the plate body 211 under the action of gravity, and at the same time the telescopic plate assembly 21 rotates relative to the fixed bottom plate 12, thereby extending the telescopic plate assembly 21. When the sliding plate 212 is switched and connected with multiple sets of connecting parts 33, the slope length and slope of the telescopic plate assembly 21 can also be changed, that is, when the sliding plate 212 is connected to the connecting part 33 closer to the fixed base plate unit 10, a shorter slope length and a larger slope can be obtained, and vice versa, a longer slope length and a smaller slope can be obtained, thereby simulating a variety of bottom shape types, and can simulate complex bottom shape types in real scenes according to actual needs, and the application scenarios are greatly expanded.

[0027] In one embodiment, the plate body 211 is provided with a limiting groove 2111 , and the sliding plate 212 is slidably inserted into the limiting groove 2111 , so that the sliding plate 212 and the plate body 211 are telescopically and slidably connected.

[0028] By sliding the sliding plate 212 into the limiting groove 2111 of the plate body 211, the sliding plate 212 can be connected to the plate body 211 in a telescopic sliding manner. When the sliding plate 212 and the plate body 211 slide relative to each other, the length of the telescopic plate assembly 21 can be changed, thereby changing the slope length of the telescopic plate assembly 21.

[0029] In one embodiment, the bridging unit 20 also includes a transverse movement mechanism 22, which includes a transverse movement member 221 slidingly arranged on the fixed base plate 12 and a transverse movement drive assembly 222 transmission-connected to the transverse movement member 221. The plate body 211 of the telescopic plate assembly 21 is hinged to the transverse movement member 221, and the transverse movement drive assembly 222 can drive the transverse movement member 221, the plate body 211 hinged to the transverse movement member 221, and the sliding plate 212 telescopically and slidably connected to the plate body 211 to move laterally.

[0030] The telescopic plate assembly 21 can be driven to move laterally relative to the fixed base plate unit 10 by the transverse movement mechanism 22, thereby changing the transverse relative position of the telescopic plate assembly 21 and the fixed base plate unit 10. When conducting a deposition physics simulation experiment, when the terrain structure undergoes horizontal displacement, the transverse movement mechanism 22 can limit the horizontal movable distance of the telescopic plate assembly 21.

[0031] like Figure 4As shown, in one embodiment, the specific structure of the transverse movement mechanism 22 is as follows: the transverse movement mechanism 22 also includes a second slide rail 223 fixed to the fixed base plate 12, the transverse member 221 includes a second slider 2211 slidably arranged on the second slide rail 223, and the transverse movement drive component 222 can adopt a linear drive module commonly found on the market, such as a linear screw module, a hydraulic cylinder module or a cylinder module. In this embodiment, the transverse movement drive component 222 adopts the following structure: the transverse movement drive component 222 includes The second motor 2221, the pull wire 2222 and the winding drum 2223 fixedly connected to the output shaft of the second motor 2221 are arranged on the fixed base plate 12 and located on the opposite sides of the second slider 2211. The two ends of the pull wire 2222 are respectively fixed to the winding drum 2223 and the second slider 2211. The second motor 2221 located on the opposite sides of the second slider 2211 can respectively drive the winding drum 2223 to rotate to retract and release the pull wire 2222, so as to pull the second slider 2211 to slide along the second slide rail 223.

[0032] The second motor 2221 can drive the winding drum 2223 to rotate to reel in and release the pulling wire 2222. When it is necessary to drive the second slider 2211 to move toward one end of the second slide rail 223, the second motor 2221 located at one end of the second slide rail 223 drives the winding drum 2223 to rotate to reel in the pulling wire 2222. The second motor 2221 located at the other end of the second slide rail 223 drives the winding drum 2223 to rotate to release the pulling wire 2222, thereby pulling the second slider 2211 to slide along the second slide rail 223.

[0033] In one embodiment, the bridging unit 20 further includes a blocking bar 23 , which is provided on the upper surface of the plate body 211 and / or the sliding plate 212 to increase the adhesion of mud and sand laid on the upper surface of the telescopic plate assembly 21 .

[0034] The blocking strips 23 can increase the resistance of the upper surface of the plate body 211 and / or the sliding plate 212 , thereby preventing the sediment deposits laid on the upper surface of the plate body 211 and the sliding plate 212 from sliding.

[0035] like Figure 7 As shown, in one embodiment, the bridging unit 20 further includes a torsion spring 24, a groove 2122 is provided on the upper surface of the sliding plate 212, the blocking bar 23 is hinged to the inner bottom surface of the groove 2122 through a pivot 25, and the torsion spring 24 is sleeved on the pivot 25, and the two ends of the torsion spring 24 are respectively in contact with the blocking bar 23 and the inner bottom surface of the groove 2122 of the sliding plate 212, so that after the sliding plate 212 slides out of the limiting groove 2111 of the plate body 211, the blocking bar 23 is elastically flipped and protrudes from the upper surface of the sliding plate 212.

[0036] The blocking bar 23 is elastically flip-mounted in the groove 2122 on the upper surface of the sliding plate 212 by the torsion spring 24. When the sliding plate 212 slides into the limiting groove 2111 of the plate body 211, the blocking bar 23 can be manually pressed into the groove 2122 to overcome the elastic force of the torsion spring 24, thereby preventing the blocking bar 23 from hindering the sliding plate 212 from sliding into the limiting groove 2111 of the plate body 211. When the sliding plate 212 slides out of the limiting groove 2111 of the plate body 211, the blocking bar 23 automatically flips over under the elastic force of the torsion spring 24 and protrudes from the upper surface of the sliding plate 212.

[0037] like Figure 3 and Figure 6 As shown, in one embodiment, the connecting portion 33 includes a sliding rod 331 provided on the upper surface of the movable base plate 31, and the end of the sliding plate 212 is provided with a sliding sleeve 2121 with an opening on one side. The sliding sleeve 2121 of the sliding plate 212 can be sleeved through the opening and abut against the sliding rod 331, so that the sliding plate 212 and the movable base plate 31 can be detachably rotatably connected.

[0038] The sliding sleeve 2121 of the sliding plate 212 can be sleeved through the opening and abut against the sliding rod 331, so that the sliding plate 212 is detachably connected to the movable base plate 31. When the sliding sleeve 2121 of the sliding plate 212 needs to be switched from one set of sliding rods 331 to another set of sliding rods 331, it is only necessary to slide the sliding plate 212, withdraw the sliding sleeve 2121 from one set of sliding rods 331 and sleeve it on the other set of sliding rods 331 through gravity. When the sliding sleeve 2121 switches the connection of the sliding rods 331, the relative position of the sliding plate 212 and the plate body 211 changes, thereby changing the slope length of the telescopic plate assembly 21, and at the same time, the angle between the plate body 211 and the fixed base plate 12 changes, thereby changing the slope of the telescopic plate assembly 21.

[0039] In one embodiment, the connecting portion 33 further includes a locking bolt 332, the movable base plate 31 is provided with a support 333, the support 333 is provided with a screw hole 334, and both ends of the sliding rod 331 are provided with through holes 335 corresponding to the screw holes 334. The sliding rod 331 is located on the support 333, and the locking bolt 332 is passed through the through hole 335 and is screwed to the screw hole 334 of the support 333, so that the sliding rod 331 and the support 333 can be detachably fixed.

[0040] The slide bar 331 is fixed to the movable bottom plate 31 by a locking bolt 332 , so that the slide bar 331 can be assembled or disassembled as needed.

[0041] In one embodiment, the movable base unit 30 also includes a translation mechanism 34, which includes a translation member 341 and a translation drive assembly 342 that is transmission-connected to the translation member 341, and the lifting mechanism 32 is fixed to the translation member 341. In this embodiment, the lifting mechanism 32 adopts a lifting cylinder, the cylinder body 321 of the lifting cylinder is fixed to the translation member 341, and the movable base 31 is fixed to the piston rod 322 of the lifting cylinder. The translation drive assembly 342 can drive the translation member 341, the lifting mechanism 32 fixed to the translation member 341, and the movable base 31 connected to the lifting mechanism 32 to move horizontally, so that the movable base 31 can be horizontally displaced relative to the fixed base 12.

[0042] The movable bottom plate 31 can be translated laterally by the translation mechanism 34, thereby changing the horizontal relative position of the movable bottom plate 31 and the fixed bottom plate 12. Since the quantitative sedimentation physics simulation experiment water tank device of the present invention adopts a combination of multiple groups of movable bottom plate units 30 and fixed bottom plate units 10 during application, after the horizontal relative position of the movable bottom plate 31 and the fixed bottom plate 12 is changed by the translation mechanism 34, more combination forms can be formed, thereby simulating more types of bottom shapes.

[0043] In one embodiment, the specific structure of the translation mechanism 34 is as follows: the translation mechanism 34 also includes a first slide rail 343, the translation member 341 includes a first slider 344 slidingly arranged on the first slide rail 343 and a support plate 345 fixedly arranged on the first slider 344, and the translation drive assembly 342 can adopt a linear drive module commonly found on the market, such as a linear screw module, a hydraulic cylinder module or a cylinder module. In this embodiment, the translation drive assembly 342 adopts a hydraulic cylinder module. More specifically, the translation drive assembly 342 includes a driving member body 3421 and a telescopic end 3422 that can be telescopically moved relative to the driving member body 3421, and the telescopic end 3422 is fixedly connected to the translation member 341. The driving member body 3421 can drive the telescopic end 3422 and the translation member 341 fixed to the telescopic end 3422 to move along the first slide rail 343.

[0044] The translation driving assembly 342 can drive the translation member 341 to move along the first slide rail 343 , thereby driving the movable base plate 31 to perform lateral translation along the first slide rail 343 .

[0045] In one embodiment, a base plate 40 is further included. The first slide rail 343 and the translation driving assembly 342 of the translation mechanism 34 are fixed on the base plate 40 . The pillars 11 of the fixed base plate unit 10 are fixed on the base plate 40 .

[0046] The base plate 40 can provide a support surface for the first slide rail 343 , the translation drive assembly 342 and the support column 11 .

[0047] When conducting a simulation experiment, the quantitative sedimentation physics simulation experiment flume device of the present invention lays felt on the surface of the fixed bottom plate unit 10, the bridge unit 20 and the movable bottom plate unit 30, and then lays mud and sand on the surface of the felt. According to the experimental needs, the movable bottom plate 31 is driven to rise and fall by the lifting mechanism 32 to obtain the required bottom shape depth, and the sliding sleeve 2121 of the sliding plate 212 is mounted on the corresponding sliding rod 331 to achieve the purpose of adjusting the slope length and slope. When the sliding sleeve 2121 is mounted on the sliding rod 331 close to the fixed bottom plate unit 10, a shorter slope length and a larger slope will be generated, otherwise a longer slope length and a smaller slope will be generated, thereby simulating the required bottom shape.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
