Description

Technical Field

[0001] This invention relates to the field of geological environment simulation experimental equipment technology, and in particular to a two-way plate tectonics physical simulation sandbox based on airbag array and its usage method. Background Technology

[0002] The bidirectional plate tectonics physical simulation sandbox based on airbag arrays is an experimental device used to study geological structures and seismic activity. Utilizing the adjustability of the airbags, it can simulate the interaction and deformation process between different plates, providing an intuitive experimental platform for geological research and helping to deepen the understanding of the Earth's internal movements and their impact on surface phenomena.

[0003] However, in practical use, the following shortcomings still exist: existing physical simulation sandboxes cannot achieve precise bidirectional multi-plate zonal motion simulation through airbag arrays to ensure experimental stability and reliability. They cannot accurately reproduce complex geological scenes. Natural plate movement is mostly bidirectional and multi-plate synergy. Unidirectional or non-zonal drive is difficult to simulate real processes such as strike-slip-collision and multi-plate convergence, leading to a disconnect between the experiment and actual geological conditions, reducing simulation accuracy. Non-zonal control is prone to uneven force transmission, causing local stress concentration or motion lag in sand bodies. It cannot accurately capture the differentiated deformation characteristics of different plates, limiting the experimental scope. It cannot conduct comparative experiments with multivariable and multi-plate interactions, making it difficult to study the main controlling factors of plate movement in depth, affecting data reliability. Unstable motion simulation can lead to deviations in experimental data such as stress and deformation, misleading geological mechanism analysis, and ultimately reducing the reference value and persuasiveness of experimental results.

[0004] Therefore, this invention proposes a physical simulation sandbox based on a two-way plate structure using airbag arrays and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a physical simulation sandbox based on a two-way plate structure using airbag arrays and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a physical simulation sandbox based on a bidirectional plate structure of airbag array and its usage method, including a base plate, and further comprising:

[0007] A drive assembly is arrayed on the base plate. The drive assembly includes a bracket connected to the top surface of the base plate. A telescopic rod is mounted on the bracket. The output end of the telescopic rod extends toward the sandbox simulation area and is connected to a frame. A spring is sleeved on the outer periphery of the telescopic rod. One end of the spring is connected to the bracket, and the other end of the spring is connected to the frame. A push plate is mounted on the side of the frame away from the telescopic rod. An accordion-style protective cover is installed between the bracket and the frame. An airbag is housed inside the accordion-style protective cover. A side plate is provided on the base plate near the edge of the push plate.

[0008] Furthermore, the airbag is equipped with an intake solenoid valve for controlling air intake, and an exhaust solenoid valve for controlling exhaust is equipped on the side of the airbag near the intake solenoid valve. The end of the exhaust solenoid valve away from the airbag is connected to an exhaust pipe, which is used to exhaust gas from the airbag.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the intake solenoid valve is responsible for opening or cutting off the air intake channel of the airbag, accurately controlling the timing and volume of high-pressure gas entry, and providing a controllable air source for airbag inflation. The exhaust solenoid valve is arranged close to the intake solenoid valve, shortening the gas exhaust path. It opens quickly when the airbag needs to contract, and the internal gas is smoothly discharged through the exhaust pipe. The two valves work together to achieve precise control of airbag inflation and deflation, ensuring the stability and response speed of the driving action, and adapting to the force requirements of plate motion simulation.

[0010] Furthermore, an air compressor is fixedly installed on the bracket, and an air tank is installed at the bottom of the air compressor. The air outlet of the air compressor is connected to the air inlet of the air tank. A connecting pipe is connected to the air compressor, and the end of the connecting pipe away from the air compressor is sealed to the air intake solenoid valve to form a stable circuit for supplying air to the airbag.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: after the air compressor starts, it generates high-pressure gas, which is delivered to the bottom air tank for storage through the air outlet. The air tank can buffer air pressure fluctuations and ensure stable output pressure. The high-pressure gas is transmitted through the connecting pipe and accurately connected to the air bag through the intake solenoid valve. The entire circuit adopts a sealed connection design to reduce gas leakage, provide a continuous and stable air supply to the air bag, and ensure the normal operation of the drive components.

[0012] Furthermore, a deep uplift simulation component is mounted on the base plate. The deep uplift simulation component includes a mounting base connected to the bottom surface of the base plate. The mounting base is a hollow structure with an open top. A first hydraulic push rod is rotatably connected to the bottom of the mounting base via a hinge. The output end of the first hydraulic push rod is rotatably connected to a connecting rod via a pin. A rotating block is rotatably connected to the connecting rod. The rotating block is rotatably connected inside the mounting base. A connecting cross plate is rotatably connected to the side of the connecting rod near the rotating block via a hinge.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the mounting base provides a stable bearing foundation for the internal components, the first hydraulic push rod achieves multi-angle rotation through the hinge seat, its telescopic motion is transmitted to the connecting rod through the pin shaft, the connecting rod drives the rotating block to rotate, and the connecting horizontal plate limits the swing range of the connecting rod through the hinge. This structure converts the linear motion of the push rod into the rotational motion of the rotating block, which plays a preliminary lifting role for the upper structure.

[0014] Furthermore, the top of the rotating block is rotatably connected to a connecting plate via a hinge. A second hydraulic push rod is installed at the center of the bottom surface of the connecting plate. The output end of the second hydraulic push rod vertically upwards through the connecting plate and is connected to a lifting plate. Guide rods are vertically connected to the four corners of the bottom surface of the lifting plate. The guide rods slide through the connecting plate. A lifting protrusion is connected to the top surface of the lifting plate. An elastic cloth is connected to the bottom plate at the position corresponding to the lifting protrusion. The elastic cloth completely covers the top of the lifting protrusion and is used to isolate the simulated sand body from the deep lifting simulation component.

[0015] The beneficial effects of adopting the above-mentioned further scheme are as follows: the rotating block drives the connecting plate to rise, the second hydraulic push rod carried by the connecting plate provides vertical lifting power, pushes the lifting plate to move up and down, the four corner guide rods slide through the connecting plate to ensure that the lifting plate rises and falls smoothly without tilting, the lifting plate drives the lifting protrusion to push the elastic cloth, the elastic cloth isolates the sand body from the components, and at the same time evenly transmits the lifting force to the sand body, accurately simulating the deep geological uplift effect.

[0016] Furthermore, a support assembly is provided on the base plate near the side plate to enhance the load-bearing stability of the side plate. The support assembly includes a support plate that is inclinedly disposed on the base plate and fits against the outer wall of the side plate. The support plate is threadedly connected to the base plate by a first bolt, and the support plate is provided with reinforcing ribs.

[0017] The beneficial effects of adopting the above-mentioned further scheme are: the support plate is inclined to fit the outer side of the side plate and is fixed to the bottom plate by the first bolt. The inclined structure can decompose the lateral pressure of the sand body on the side plate into vertical and horizontal components, reduce the local stress, and the reinforcing rib enhances the support plate's resistance to bending deformation. The whole forms a stable force transmission path, which evenly distributes the force on the side plate to the bottom plate, greatly improves the load-bearing stability of the side plate, and prevents displacement during simulation.

[0018] Furthermore, the side plate is threadedly connected to the base plate by a second bolt, thereby achieving detachable fixing of the side plate and the base plate. A retaining seat is connected to the side plate near the top of the support plate. The retaining seat has a U-shaped groove structure, and the top of the support plate is embedded in the U-shaped groove of the retaining seat to form a limiting support for the top of the side plate.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the second bolt can detachably fix the side plate to the base plate, taking into account both the connection firmness and the convenience of later maintenance. The U-shaped bracket at the top of the side plate is embedded in the top of the support plate. This structure restricts the vertical and lateral displacement of the side plate, avoids the displacement or deformation caused by the pressure of the sand body, and at the same time disperses the force on the top of the side plate to ensure accurate simulation of the sand body boundary.

[0020] The usage method of the bidirectional plate structure physics simulation sandbox based on airbag array is as follows:

[0021] S1. This sand box simulation device achieves accurate simulation of sand plate movement and deep geological processes through the coordinated operation of the drive component, deep uplift simulation component, and support component. During operation, the air compressor on the support frame generates high-pressure gas, which is delivered to the bottom air tank for storage through the outlet. The air tank effectively buffers pressure fluctuations, ensuring stable output pressure. The high-pressure gas is transmitted to the intake solenoid valve through a connecting pipe. The intake solenoid valve precisely controls the timing and volume of gas supply. Once opened, the high-pressure gas enters the airbag inside the bellows-style protective cover, causing the airbag to inflate. The inflated airbag propels the frame toward the sand box simulation area. Simultaneously, the frame drives the push plate to move the sand body simulation plates. During this process, the telescopic rod extends synchronously, and the outer spring is stretched to store energy. When reverse movement or stopping is required, the exhaust solenoid valve opens quickly, and the gas in the airbag is smoothly discharged through the exhaust pipe. The spring releases its stored energy and resets, pulling the frame and push plate back to the initial position. The bellows-style protective cover protects the airbag throughout the process to prevent the sand body from damaging the airbag. The array of multiple drive components, together with the solenoid valve for precise control, realizes multi-plate zone movement simulation.

[0022] S2 and the deep uplift simulation components work in sync to simulate the uplift effect of deep geological formations. The mounting base provides stable support for the internal components. The first hydraulic push rod inside rotates at multiple angles through the hinge. The telescopic motion is transmitted to the connecting rod via the pin shaft. The connecting rod drives the rotating block to rotate. The connecting plate limits the swing range of the connecting rod through the hinge. The upper structure is initially lifted. The rotating block drives the connecting plate to rise. The second hydraulic push rod on the connecting plate provides vertical lifting power, pushing the uplift plate to move up and down. The guide rods at the four corners of the bottom surface of the uplift plate slide through the connecting plate to ensure a smooth and tilt-free lifting process. The uplift protrusion at the top of the uplift plate pushes the elastic cloth on the bottom plate. The elastic cloth isolates the sand body from the components while uniformly transmitting the uplift force to the sand body, accurately replicating the deep uplift effect.

[0023] S3. The support assembly provides stability for the simulation process and enhances the load-bearing capacity of the side plate. The side plate is detachably fixed to the base plate by the second bolt, balancing sturdiness and ease of maintenance. The inclined support plate fits against the outer wall of the side plate and is fixed to the base plate by the first bolt. The inclined structure decomposes the lateral pressure of the sand body on the side plate into vertical and horizontal components, reducing local stress. The reinforcing ribs on the support plate further enhance its bending resistance. The U-shaped bracket at the top of the side plate is embedded in the top of the support plate to form a top limiting support, restricting the vertical and lateral displacement of the side plate. The side plate at the edge of the base plate precisely defines the sand body boundary, and together with the support assembly, avoids displacement deformation caused by sand body pressure, ensuring the stability and reliability of the simulation process. All components work together to achieve accurate simulation of bidirectional multi-plate movement and deep uplift.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] 1. In this invention, after the air compressor starts, it stores high-pressure gas in the air tank. The air tank supplies gas to the airbag through the connecting pipe. When the intake solenoid valve is opened, the high-pressure gas enters the airbag and causes it to expand, pushing the frame to move towards the simulation area. The frame drives the push plate to push the sand body simulation plate to move. At this time, the telescopic rod extends synchronously, and the spring is stretched to store energy. When it is necessary to reverse the movement or stop, the exhaust solenoid valve is opened, and the gas in the airbag is discharged through the exhaust pipe. The spring resets and pulls the frame and push plate back. The bellows-style protective cover protects the airbag. The array-arranged pneumatic drive components work with the solenoid valve for precise control. The side plate limits the sand body boundary to ensure the stability of the simulation, realizing bidirectional multi-plate precise zoned motion simulation, ensuring the stability and reliability of the experiment.

[0026] 2. In this invention, the mounting base provides a stable bearing foundation for the entire assembly. The first hydraulic push rod achieves multi-angle rotation through the hinge seat. Its telescopic motion is transmitted to the connecting rod via the pin shaft, driving the rotating block to rotate. The connecting horizontal plate limits the swing range of the connecting rod through the hinge, converting the linear motion of the push rod into the rotational motion of the rotating block, realizing the initial lifting of the upper structure. The rotating block drives the connecting plate to lift synchronously. The second hydraulic push rod carried by the connecting plate provides the core vertical lifting power, pushing the lifting plate to move up and down. The four corner guide rods slide through the connecting plate to ensure that the lifting plate lifts smoothly without tilting. The lifting plate drives the lifting protrusion to push the elastic cloth. The elastic cloth not only isolates the sand body from the assembly, but also evenly transmits the lifting force, accurately simulating the deep geological uplift effect. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: a physical simulation sandbox based on a bidirectional plate structure using an airbag array and its usage method, including a base plate 1, and further including:

[0042] A drive assembly 2 is arrayed on the base plate 1. The drive assembly 2 includes a bracket 21 connected to the top surface of the base plate 1. A telescopic rod 22 is mounted on the bracket 21. The output end of the telescopic rod 22 extends toward the sandbox simulation area and is connected to a frame 23. A spring 24 is sleeved on the outer periphery of the telescopic rod 22. One end of the spring 24 is connected to the bracket 21, and the other end of the spring 24 is connected to the frame 23. A push plate 25 is mounted on the side of the frame 23 away from the telescopic rod 22. An accordion-style protective cover 26 is installed between the bracket 21 and the frame 23. An airbag 27 is housed inside the accordion-style protective cover 26. A side plate 214 is provided on the base plate 1 near the edge of the push plate 25. After the air compressor 211 is started, it stores high-pressure gas into the air storage tank 212. Air is supplied to the airbag 27 through the connecting pipe 213. When the air intake solenoid valve 28 is opened, high-pressure gas enters the airbag 27, causing it to expand and push the frame 23 to move towards the simulation area. The frame 23 drives the push plate 25 to push the sand body simulation plate to move. At this time, the telescopic rod 22 extends synchronously, and the spring 24 is stretched to store energy. When it is necessary to reverse the movement or stop, the exhaust solenoid valve 29 opens, and the gas in the airbag 27 is discharged through the exhaust pipe 210. The spring 24 resets and pulls the frame 23 and the push plate 25 back. The bellows-style protective cover 26 protects the airbag 27. The array-arranged pneumatic drive components 2 work in conjunction with the solenoid valve for precise control. The side plate 214 limits the sand body boundary to ensure simulation stability, realizing bidirectional multi-plate precise zoned motion simulation, ensuring the stability and reliability of the experiment.

[0043] like Figure 1 - Figure 5As shown, the airbag 27 is equipped with an intake solenoid valve 28 for controlling air intake, and an exhaust solenoid valve 29 for controlling exhaust is equipped on the side of the airbag 27 near the intake solenoid valve 28. The end of the exhaust solenoid valve 29 away from the airbag 27 is connected to an exhaust pipe 210, which is used to exhaust gas from the airbag 27. The intake solenoid valve 28 is responsible for opening or closing the air intake channel of the airbag 27, precisely controlling the timing and volume of high-pressure gas entry, and providing a controllable gas source for the inflation of the airbag 27. The exhaust solenoid valve 29 is arranged close to the intake solenoid valve 28 to shorten the gas exhaust path. It opens quickly when the airbag 27 needs to contract, and the internal gas is smoothly discharged through the exhaust pipe 210. The two valves work together to achieve precise control of the inflation and deflation of the airbag 27, ensuring the stability and response speed of the driving action, and adapting to the plate motion model. To meet the required force, an air compressor 211 is fixedly installed on the bracket 21. An air tank 212 is installed at the bottom of the air compressor 211. The air outlet of the air compressor 211 is connected to the air inlet of the air tank 212. A connecting pipe 213 is connected to the air compressor 211. The end of the connecting pipe 213 away from the air compressor 211 is sealed to the air intake solenoid valve 28, forming a stable circuit for supplying air to the airbag 27. After the air compressor 211 starts, it generates high-pressure gas, which is delivered to the bottom air tank 212 for storage through the air outlet. The air tank 212 can buffer air pressure fluctuations to ensure stable output pressure. The high-pressure gas is transmitted through the connecting pipe 213 and accurately connected to the airbag 27 through the air intake solenoid valve 28. The entire circuit adopts a sealed connection design to reduce gas leakage, provide a continuous and stable air supply to the airbag 27, and ensure the normal operation of the drive component 2.

[0044] like Figure 2 - Figure 3 as well as Figure 6 - Figure 7As shown, a deep uplift simulation component 3 is mounted on the base plate 1. The deep uplift simulation component 3 includes a mounting base 31 connected to the bottom surface of the base plate 1. The mounting base 31 is a hollow structure with an open top. A first hydraulic push rod 32 is rotatably connected to the bottom of the mounting base 31 via a hinge. The output end of the first hydraulic push rod 32 is rotatably connected to a connecting rod 33 via a pin. A rotating block 34 is rotatably connected to the connecting rod 33. The rotating block 34 is rotatably connected inside the mounting base 31. A connecting horizontal plate 35 is rotatably connected to the side of the connecting rod 33 near the rotating block 34 via a hinge. The mounting base 31 provides a stable bearing foundation for the internal components. The first hydraulic push rod 32 can rotate at multiple angles via the hinge. Its telescopic motion is transmitted to the connecting rod 33 via the pin. The connecting rod 33 drives the rotating block 34 to rotate. The connecting horizontal plate 35 limits the swing range of the connecting rod 33 via a hinge. This structure converts the linear motion of the push rod into the rotational motion of the rotating block 34, which plays a preliminary lifting role for the upper structure. A connecting plate is rotatably connected to the top of the rotating block 34 via a hinge. 36. A second hydraulic push rod 37 is installed at the center of the bottom surface of the connecting plate 36. The output end of the second hydraulic push rod 37 vertically extends upward through the connecting plate 36 and connects to a lifting plate 38. Guide rods 39 are vertically connected to the four corners of the bottom surface of the lifting plate 38. The guide rods 39 slide through the connecting plate 36. A lifting protrusion 310 is connected to the top surface of the lifting plate 38. An elastic cloth 311 is connected to the bottom plate 1 at the position corresponding to the lifting protrusion 310. The elastic cloth 311 completely covers the top of the lifting protrusion 310. The rotating block 34 drives the connecting plate 36 to lift, and the second hydraulic push rod 37 carried by the connecting plate 36 provides vertical lifting power to push the lifting plate 38 to move up and down. The four corner guide rods 39 slide through the connecting plate 36 to ensure that the lifting plate 38 rises and falls smoothly without tilting. The lifting plate 38 drives the lifting protrusion 310 to push the elastic cloth 311. The elastic cloth 311 isolates the sand body and the component, and at the same time evenly transmits the lifting force to the sand body to accurately simulate the deep geological uplift.

[0045] like Figure 1 - Figure 2 as well as Figure 8As shown, a support assembly 4 is provided on the base plate 1 near the side plate 214 to enhance the load-bearing stability of the side plate 214. The support assembly 4 includes a support plate 41 that is inclinedly disposed on the base plate 1 and fits against the outer wall of the side plate 214. The support plate 41 is threadedly connected to the base plate 1 by a first bolt 42. A reinforcing rib 43 is provided on the support plate 41. The support plate 41 is inclinedly fitted against the outer side of the side plate 214 and fixed to the base plate 1 by the first bolt 42. The inclined structure can decompose the lateral pressure of the sand body borne by the side plate 214 into vertical and horizontal components, reducing local stress. The reinforcing rib 43 enhances the bending deformation resistance of the support plate 41, forming a stable force transmission path and evenly distributing the force on the side plate 214 to the base plate 1, significantly improving the load-bearing capacity of the side plate 214. To ensure stability and prevent displacement during simulation, the side plate 214 is threadedly connected to the base plate 1 via the second bolt 44, enabling detachable fixing of the side plate 214 and the base plate 1. A retaining seat 45 is connected to the side of the side plate 214 near the top of the support plate 41. The retaining seat 45 has a U-shaped groove structure, and the top of the support plate 41 is embedded in the U-shaped groove of the retaining seat 45, forming a limiting support for the top of the side plate 214. The second bolt 44 detachably fixes the side plate 214 to the base plate 1, taking into account both connection firmness and ease of later maintenance. The U-shaped retaining seat 45 on the top of the side plate 214 is embedded in the top of the support plate 41. This structure restricts the vertical and lateral displacement of the side plate 214, avoiding displacement or deformation caused by sand pressure, while dispersing the force on the top of the side plate 214 to ensure accurate simulation of the sand boundary.

[0046] like Figure 1 - Figure 8 As shown, the usage method of this bidirectional plate construction physics simulation sandbox based on airbag array is as follows:

[0047] S1. This sandbox simulation device, through the coordinated operation of the drive component 2, the deep uplift simulation component 3, and the support component 4, achieves accurate simulation of sand plate movement and deep geological processes. During operation, the air compressor 211 on the support 21 starts to generate high-pressure gas, which is then transported through the outlet to the bottom air storage tank 212 for storage. The air storage tank 212 effectively buffers pressure fluctuations, ensuring stable output pressure. The high-pressure gas is transmitted to the intake solenoid valve 28 through the connecting pipe 213. The intake solenoid valve 28 precisely controls the timing and volume of gas supply. After opening, the high-pressure gas enters the airbag 27 inside the bellows-style protective cover 26, causing the airbag 27 to inflate. The airbag 27 pushes the frame 23 to move towards the sand box simulation area. The frame 23 simultaneously drives the push plate 25 to push the sand body simulation plate to move. During this process, the telescopic rod 22 extends synchronously, and the outer peripheral spring 24 is stretched and stores energy. When it is necessary to reverse the movement or stop, the exhaust solenoid valve 29 opens quickly, and the gas in the airbag 27 is smoothly discharged through the exhaust pipe 210. The spring 24 releases its stored energy and resets, pulling the frame 23 and the push plate 25 back to the initial position. The bellows-style protective cover 26 protects the airbag 27 throughout the process to prevent the sand body from damaging the airbag 27. The array-arranged multiple sets of drive components 2, together with the solenoid valve, are precisely controlled to realize the multi-plate zone movement simulation.

[0048] S2 and the deep uplift simulation component 3 work in sync to simulate the deep geological uplift. The mounting base 31 provides stable support for the internal components. The first hydraulic push rod 32 inside it can rotate at multiple angles through the hinge. The telescopic motion is transmitted to the connecting rod 33 through the pin shaft. The connecting rod 33 drives the rotating block 34 to rotate. The connecting horizontal plate 35 limits the swing range of the connecting rod 33 through the hinge. The upper structure is initially lifted. The rotating block 34 drives the connecting plate 36 to rise. The second hydraulic push rod 37 on the connecting plate 36 provides vertical lifting power and pushes the uplift plate 38 to move up and down. The guide rods 39 at the four corners of the bottom surface of the uplift plate 38 slide through the connecting plate 36 to ensure that the lifting process is smooth and without tilting. The uplift protrusion 310 on the top of the uplift plate 38 pushes the elastic cloth 311 on the bottom plate 1. The elastic cloth 311 isolates the sand body from the component and transmits the uplift force evenly to the sand body, accurately replicating the deep uplift effect.

[0049] S3 and support components 4 provide stability for the simulation process and enhance the load-bearing capacity of side plate 214. Side plate 214 is detachably fixed to base plate 1 by second bolt 44, balancing sturdiness and ease of maintenance. The inclined support plate 41 fits against the outer wall of side plate 214 and is fixed to base plate 1 by first bolt 42. The inclined structure decomposes the lateral pressure of sand body on side plate 214 into vertical and horizontal components, reducing local stress. The reinforcing ribs 43 on support plate 41 further enhance its bending resistance. The U-shaped bracket 45 at the top of side plate 214 is embedded in the top of support plate 41 to form a top limiting support, restricting the vertical and lateral displacement of side plate 214. The side plate 214 at the edge of base plate 1 precisely defines the sand body boundary, and together with support components 4, avoids displacement deformation caused by sand body pressure, ensuring the stability and reliability of the simulation process. All components work together to achieve accurate simulation of bidirectional multi-plate movement and deep uplift.

8. A method for using a two-way plate structure physics simulation sandbox based on an airbag array, as described in any one of claims 1-7, characterized in that... The usage method of this two-way plate construction physics simulation sandbox based on airbag array is as follows: S1. The sand box simulation device achieves accurate simulation of sand plate movement and deep geological processes through the coordinated operation of the drive component (2), the deep uplift simulation component (3), and the support component (4). When the device is working, the air compressor (211) on the support (21) starts to generate high-pressure gas, which is delivered to the bottom air tank (212) for storage through the air outlet. The air tank (212) can effectively buffer air pressure fluctuations and ensure stable output pressure. The high-pressure gas is transmitted to the air intake solenoid valve (28) through the connecting pipe (213). The air intake solenoid valve (28) accurately controls the timing and volume of air supply. After opening, the high-pressure gas enters the airbag (27) in the bellows-type protective cover (26), causing the airbag (27) to expand. The expanded airbag (27) Push the frame (23) to move towards the sand box simulation area. The frame (23) simultaneously drives the push plate (25) to push the sand body simulation plate to move. During this process, the telescopic rod (22) extends synchronously, and the outer peripheral spring (24) is stretched and stored. When it is necessary to reverse the movement or stop, the exhaust solenoid valve (29) opens quickly, and the gas in the airbag (27) is smoothly discharged through the exhaust pipe (210). The spring (24) releases the stored energy and resets, pulling the frame (23) and the push plate (25) back to the initial position. The bellows-style protective cover (26) protects the airbag (27) throughout the process to prevent the sand body from damaging the airbag (27). The array-arranged multiple sets of drive components (2) work together with the solenoid valve for precise control to realize the multi-plate partition movement simulation. S2 and the deep uplift simulation component (3) work in sync to simulate the deep geological uplift. The mounting base (31) provides stable support for the internal components. The first hydraulic push rod (32) inside the mounting base rotates at multiple angles through the hinge. The telescopic motion is transmitted to the connecting rod (33) through the pin shaft. The connecting rod (33) drives the rotating block (34) to rotate. The connecting horizontal plate (35) limits the swing range of the connecting rod (33) through the hinge. The upper structure is initially lifted. The rotating block (34) drives the connecting plate (36). Lifting, the second hydraulic push rod (37) on the connecting plate (36) provides vertical lifting power, pushing the lifting plate (38) to move up and down. The guide rods (39) at the four corners of the bottom surface of the lifting plate (38) slide through the connecting plate (36) to ensure that the lifting process is stable and without tilting. The lifting protrusion (310) on the top of the lifting plate (38) pushes the elastic cloth (311) on the bottom plate (1). The elastic cloth (311) isolates the sand body from the components while uniformly transmitting the lifting force to the sand body, accurately replicating the deep lifting effect. S3, the support assembly (4) provides stability for the simulation process and strengthens the load-bearing capacity of the side plate (214). The side plate (214) is detachably fixed to the base plate (1) by the second bolt (44), taking into account both firmness and ease of maintenance. The inclined support plate (41) fits against the outer wall of the side plate (214) and is fixed to the base plate (1) by the first bolt (42). The inclined structure decomposes the lateral pressure of the sand body borne by the side plate (214) into vertical and horizontal components, reducing local stress. The reinforcing ribs (43) on (41) further enhance its bending resistance. The U-shaped bracket (45) on the top of the side plate (214) is fitted with the top of the support plate (41) to form a top limiting support, which restricts the vertical and horizontal displacement of the side plate (214). The side plate (214) on the edge of the bottom plate (1) precisely defines the sand body boundary. Together with the support components (4), it avoids the displacement deformation caused by the sand body pressure, ensuring the stability and reliability of the simulation process. All components work together to achieve accurate simulation of bidirectional multi-plate movement and deep uplift.
