Description

Technical Field

[0001] This invention relates to the field of geological sedimentation, and more specifically to a geological sedimentation simulation device. Background Technology

[0002] In the field of oil and gas, sedimentary simulation experiments are an important branch of sedimentology research. As an important experiment for observing and recording the evolution of sediment-mud mixtures and reproducing the sedimentary process, tectonic evolution law and hydrodynamic mechanism of sand bodies, geological sedimentary simulation experiments have important guiding role and application value for oil and gas exploration and development.

[0003] The geological sedimentation simulation device includes a movable panel and a lifting system. The bottom of the movable panel is equipped with a mounting base, and the movable panel is connected to the lifting system through the mounting base. When the geological sedimentation simulation device is adjusted, the lifting systems cooperate with each other to drive the movable panel to tilt. During this process, the projection distance of the mounting base on the horizontal plane changes, while the projection distance between the lifting systems remains unchanged, which makes it impossible for the movable panel to adjust its posture.

[0004] The current cross-slide mechanism compensates for the displacement of the mounting base and is used to release the X and Y degrees of freedom of the mounting base. The cross-slide mechanism is set at the bottom of the movable panel and a lead screw is installed inside the cross-slide mechanism. When the movable panel is tilted, the lead screw slides along the cross-slide mechanism to compensate for the displacement of the mounting base. In actual use, there is a problem of uneven displacement compensation at the cross joint of the cross-slide mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide a geological sedimentation simulation device, and the technical problem to be solved is that the device does not operate smoothly during the displacement compensation process.

[0006] This invention is achieved through the following technical solution:

[0007] A geological sedimentation simulation device, comprising:

[0008] The movable panel and displacement compensation component, wherein the displacement compensation component includes a connecting block and a hollow structure having a first cavity, the connecting block being placed inside the first cavity of the hollow structure, and a clearance being left between the connecting block and the inner wall of the hollow structure.

[0009] The aforementioned hollow structure is located on the bottom surface of the movable panel;

[0010] The connecting block is provided with a spherical crown groove on the side away from the movable panel, and the hollow structure is provided with a first through hole on the side away from the movable panel, which communicates with the first cavity.

[0011] The lifting assembly includes a ball screw and a drive assembly, wherein the drive assembly is connected to the ball screw and is used to drive the ball screw to move up and down.

[0012] The ball end of the aforementioned ball screw passes through the first through hole and is nested in the ball crown groove.

[0013] The aforementioned drive assembly drives the ball screw to move up and down. The ball screw is connected to the connecting block. Because there is a margin between the connecting block and the inner wall of the hollow structure, the connecting block can slide in the first cavity. When the drive assembly drives the movable panel to tilt, it ensures that the projection distance of the connecting block of the ball screw on the horizontal plane remains constant, and the projection distance between the lifting components also remains constant, thus realizing the posture adjustment movement of the movable panel.

[0014] The ball end of the ball screw is nested in the spherical groove of the connecting block, which not only achieves fixation but also allows rotation when the ball screw moves up and down. This initially solves the problem of the connecting block not running smoothly during displacement compensation. Furthermore, the connecting block only slides within the first cavity, which further solves the problem of the connecting block not running smoothly during displacement compensation.

[0015] Furthermore, the inner wall of the hollow structure is provided with an oil groove, which is used to fill lubricating oil.

[0016] The aforementioned oil groove is located on the inner wall of the hollow structure, and the connecting block slides within the central control structure. Filling the oil groove with lubricating oil further solves the problem of the connecting block not moving smoothly during the displacement compensation process.

[0017] Furthermore, the aforementioned lifting assembly also includes a frame, which is provided with a second through hole and a second cavity. The second through hole communicates with the second cavity. The aforementioned drive assembly is connected to the frame, and the aforementioned ball screw passes through the second through hole and extends into the second cavity.

[0018] The aforementioned second cavity serves as the receiving cavity for the ball-end screw.

[0019] Furthermore, anchor bolts are also provided on the aforementioned frame for securing it.

[0020] Furthermore, the aforementioned drive components include a worm gear structure, a planetary reducer, and a power source.

[0021] The worm gear structure described above includes a worm gear and a worm, wherein the worm gear meshes with the worm and the ball-end screw;

[0022] The aforementioned worm gear is connected to the output end of the planetary reducer;

[0023] The input end of the aforementioned planetary reducer is connected to the power source.

[0024] The aforementioned planetary reducer constitutes the first reducer, and the worm gear and worm constitute the second reducer. Simulating geological changes requires a long time, and the drive components need to have a large reduction ratio. The first and second reducers are used to meet this reduction ratio.

[0025] Furthermore, the aforementioned power source includes an electric motor, which is connected to the first input terminal of the planetary reducer.

[0026] The aforementioned motor drives the worm gear structure to rotate, and the rotating worm gear structure causes the ball screw to rise or fall.

[0027] Furthermore, the aforementioned power source also includes a handwheel, which is connected to the second input terminal of the planetary reducer.

[0028] Furthermore, the hollow structure includes a first plate and a second plate, the middle part of the first plate is provided with a groove, and the first through hole is provided on the groove;

[0029] The edge of the first plate is in contact with the second plate and is fixed to the bottom surface of the movable panel;

[0030] The aforementioned groove and the second plate form a first cavity.

[0031] Furthermore, the middle part of the second plate is provided with a protrusion, which is fitted into the groove and forms a snap-fit ​​with the groove.

[0032] When the aforementioned driving component tilts the movable panel, the protrusion of the second plate abuts against the inner wall of the groove of the first plate, preventing the first plate from sliding relative to the second plate.

[0033] Furthermore, the aforementioned active panel is equipped with at least four of the aforementioned displacement compensation components, each of which is connected to the aforementioned lifting component.

[0034] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0035] The aforementioned drive assembly drives the ball screw to move up and down. The ball screw is connected to the connecting block. Because there is a margin between the connecting block and the inner wall of the hollow structure, the connecting block can slide in the first cavity. When the drive assembly drives the movable panel to tilt, it ensures that the projection distance of the connecting block of the ball screw on the horizontal plane remains constant, and the projection distance between the lifting components also remains constant, thus realizing the posture adjustment movement of the movable panel.

[0036] The ball end of the ball screw is nested in the spherical groove of the connecting block, which not only achieves fixation but also allows rotation when the ball screw moves up and down. This initially solves the problem of the connecting block not running smoothly during displacement compensation. Furthermore, the connecting block only slides within the first cavity, which further solves the problem of the connecting block not running smoothly during displacement compensation.

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0050] A geological sedimentation simulation device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: a movable panel 1, a displacement compensation component 2, and a lifting component 3. The movable panel 1 is used to carry the mixture of mud and sand flow, and the movable panel 1 is rectangular.

[0051] Four displacement compensation components 2 are symmetrically arranged diagonally on the bottom surface of the aforementioned movable panel 1 to compensate for the displacement difference generated during the lifting and lowering of the movable panel 1;

[0052] Each displacement compensation component 2 is connected to a lifting component 3, and the movable panel can achieve different motion postures such as lifting and tilting through program control.

[0053] The displacement compensation component 2 includes a connecting block 220 and a hollow structure 210 with a first cavity 214. The connecting block 220 is placed inside the first cavity 214 of the hollow structure 210, and there is a margin between the connecting block 220 and the inner wall of the hollow structure 210 to achieve displacement compensation during the lifting process.

[0054] The hollow structure 210 is provided on the bottom surface of the movable panel 1;

[0055] The connecting block 220 is provided with a spherical crown groove 223 on the side away from the movable panel 1, and the hollow structure 210 is provided with a first through hole 213 on the side away from the movable panel 1. The first through hole 213 communicates with the first cavity 214.

[0056] The aforementioned lifting assembly 3 includes a ball screw 31 and a drive assembly 32. The drive assembly 32 is connected to the ball screw 31 and is used to drive the ball screw 31 to move up and down.

[0057] The ball end of the ball screw 31 passes through the first through hole 213 and is nested in the ball crown groove 223.

[0058] The aforementioned drive assembly 32 drives the ball screw 31 to move up and down. The ball screw 31 is connected to the connecting block 220. Because there is a margin between the connecting block 220 and the inner wall of the hollow structure 210, the connecting block 220 can slide in the first cavity 214. When the drive assembly 32 drives the movable panel 1 to tilt, it ensures that the projection distance of the connecting block 220 of the ball screw 31 on the horizontal plane remains constant, and the projection distance between the lifting assemblies 3 also remains constant, thus realizing the posture adjustment movement of the movable panel 1.

[0059] The ball end of the ball screw 31 is nested in the ball crown groove 223 of the connecting block 220, which not only achieves fixation, but also allows rotation when the ball screw moves up and down, thus initially solving the problem of the connecting block 220 not running smoothly during displacement compensation. Furthermore, the connecting block 220 only slides within the first cavity 214, further solving the problem of the connecting block 220 not running smoothly during displacement compensation.

[0060] Specific implementation examples, such as Figure 4 As shown, the inner wall of the hollow structure 210 is provided with an oil groove 215, which is used to fill lubricating oil.

[0061] The oil groove 215 is set on the inner wall of the hollow structure 210, and the connecting block 220 slides in the central control structure. The filling of the oil groove 215 with lubricating oil further solves the problem of the connecting block 220 not moving smoothly during the displacement compensation process.

[0062] Specific implementation examples, such as Figure 5 and Figure 6 As shown, the lifting assembly 3 also includes a frame 33, which is provided with a second through hole 332 and a second cavity 331. The second through hole 332 communicates with the second cavity 331. The drive assembly 32 is connected to the frame 33. The ball screw 31 passes through the second through hole 332 and extends into the second cavity 331.

[0063] The aforementioned frame 33 serves to support the entire geological sedimentation simulation device, and the aforementioned second cavity 331 serves as the receiving cavity for the ball-end screw 31.

[0064] In a specific embodiment, the frame 33 is also provided with anchor bolts (not shown in the figure), which are fixed to the ground.

[0065] Specific implementation examples, such as Figure 9 As shown, the aforementioned drive assembly 32 includes a worm gear structure 321, a planetary reducer 323, and a power source.

[0066] The aforementioned worm gear structure 321 includes a worm gear 326 and a worm 325, wherein the worm gear 326 meshes with the worm 325 and the ball screw 31;

[0067] The aforementioned worm gear 325 is connected to the output end of the planetary reducer 323;

[0068] The input end of the aforementioned planetary reducer 323 is connected to the power source.

[0069] The aforementioned worm gear 326 and worm 325 constitute a reduction mechanism. The worm 325 rotates at high speed, while the worm gear 326 rotates at slow speed. A female thread is provided in the middle part of the worm gear 326, and the ball screw 31 passes through the middle part to form a screw jack. Since geological sedimentation simulation experiments need to simulate the process of strata change on a certain time scale, and this change often takes a long time, the lifting component 3 needs to have a large reduction ratio. Therefore, the power source, planetary reducer 323, and the reduction mechanism composed of worm gear 326 and worm 325 are used as the driving source of the drive component 32.

[0070] In a specific embodiment, the power source includes a servo motor 322, which is connected to the first input terminal of a planetary reducer 323.

[0071] The aforementioned motor 322 drives the ball screw 31 to rise or fall via the planetary reducer 323 and the worm gear structure 321.

[0072] In a specific embodiment, the power source also includes a handwheel 324, which is connected to the second input terminal of the planetary reducer 323.

[0073] In the event of an unexpected power outage, the ball screw 31 can be raised or lowered using the handwheel 324.

[0074] Specific implementation examples, such as Figure 3 As shown, the hollow structure 210 includes a first plate 211 and a second plate 212. The oil groove 215 is disposed on the second plate 212. The middle part of the first plate 211 is provided with a groove, and the first through hole 213 is disposed on the groove.

[0075] The edge portion of the first plate 211 contacts the second plate 212 and is fixed to the bottom surface of the movable panel 1;

[0076] The aforementioned groove and the second plate 212 enclose each other to form the first cavity 214.

[0077] In a specific embodiment, the middle part of the second plate 212 is provided with a protrusion, which is fitted into the groove and forms a snap-fit ​​with the groove.

[0078] When the aforementioned drive assembly 32 drives the movable panel 1 to tilt, the protrusion of the second plate 212 abuts against the inner wall of the groove of the first plate 211, preventing the first plate 211 and the second plate 212 from sliding relative to each other.

[0079] In a specific embodiment, the connecting block 220 is composed of an upper connecting plate 221 and a lower connecting plate 222.

[0080] The working process of this device is as follows: when the movable panel 1 is adjusted in position, the four ball screws 31 are controlled to move up and down, thereby realizing the tilting of the movable panel 1. The connecting block 220 of the displacement compensation component 2 also tilts with the movable panel 1. The connecting block 220 moves in the first cavity 214 to complete the displacement compensation process of the connecting block 220.

[0081] The four ball screws 31 are, in counterclockwise order, the first ball screw 311, the second ball screw 312, the third ball screw 313, and the fourth ball screw 314;

[0082] like Figure 1 As shown, the overall lifting motion is as follows: the four ball screws 31 move up or down at the same speed, driving the movable panel 1 to rise or fall.

[0083] like Figure 7 As shown, the axial tilting motion is as follows: tilting is performed with the central axis of the movable panel 1 as the axis of symmetry, and the first ball screw 311 and the second ball screw 312 are symmetrical about this axis of symmetry, while the third ball screw 313 and the fourth ball screw 314 are symmetrical about this axis of symmetry. This example is for illustration purposes only and does not limit the scope of protection.

[0084] The first ball screw 311 and the fourth ball screw 314 move upward at the same speed, while the second ball screw 312 and the third ball screw 313 move downward at the same speed. During the axial tilting process of the lifting assembly 3 driving the movable panel 1, the connecting block 220 in the displacement compensation assembly 2 slides within the first cavity 214 as the movable panel 1 tilts. The connecting block 220 located at the higher position (connected to the first ball screw 311 and the fourth ball screw 314) performs displacement compensation towards the higher position of the movable panel 1, while the connecting block 220 located at the lower position (connected to the second ball screw 312 and the third ball screw 313) performs displacement compensation towards the lower position of the movable panel 1, thereby achieving displacement compensation during the tilting process of the movable panel 1.

[0085] like Figure 8 As shown, the diagonal tilting motion is as follows: the tilting is performed with the diagonal of the movable panel 1 as the axis of symmetry, and the line connecting the first ball screw 311 and the third ball screw 313 is taken as the axis of symmetry. The second ball screw 312 and the fourth ball screw 314 are stacked about this axis of symmetry as an example for illustration. This example does not limit the scope of protection.

[0086] The first ball screw 311 moves upward at a certain speed, the third ball screw 313 moves downward at another speed, and the second ball screw 312 and the fourth ball screw 314 maintain a speed value between the two speeds of the former to move upward or downward. During the diagonal tilting process of the lifting assembly 3 driving the movable panel 1, the connecting block 220 in the displacement compensation assembly 2 slides in the first cavity 214 as the movable panel 1 tilts. Among them, the connecting block 220 located at the high position (the connecting block 220 connected to the first ball screw 311) performs displacement compensation towards the high position of the movable panel 1, and the connecting block 220 located at the low position (the connecting block 220 connected to the third ball screw 313) performs displacement compensation towards the low position of the movable panel 1, thereby realizing displacement compensation during the tilting process of the movable panel 1. The displacement compensation principle of the connecting block 220 in the diagonal tilting movement is the same as the displacement compensation principle of the connecting block 220 in the axial tilting movement.

[0087] This allows the geological sedimentation simulation device to smoothly complete axial tilting and diagonal tilting movements.

[0088] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
