DETAILED DESCRIPTION

[0028] 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 technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Geological disasters, as a phenomenon formed by the combined effects of natural or human factors, have caused extremely serious damage and losses to human life, property and ecological environment. Earthquakes, caused by the violent movement of crustal plates, release huge energy in the form of seismic waves, which can instantly paralyze cities, collapse a large number of buildings, and bury countless lives. Their destructive power is extremely sudden and destructive. Landslides are natural phenomena in which the rock and soil on the slope of a mountain slide down the slope as a whole or in a dispersed manner along a certain weak surface or weak zone under the action of gravity. Landslides will not only bury houses and block traffic, but may also cause secondary disasters, further aggravating the degree of harm. Mudslides are special torrents in mountain valleys, triggered by water sources such as heavy rains and meltwater from ice and snow. They contain a large amount of mud, sand and stones. They flow fast and have great impact. Wherever they go, everything is swept away. Ground subsidence is usually a phenomenon of lowering ground elevation caused by long-term over-exploitation of groundwater, human activities such as engineering construction, and natural factors such as crustal movement. It can damage urban infrastructure and cause cracks, tilts, and even collapses in buildings.

[0030] In today's society, it is crucial to raise people's awareness and prevention of geological disasters. It is an effective means of popular science and education to intuitively present the occurrence process and hazards of geological disasters through model display devices. However, there are many disadvantages in the existing geological disaster model display devices. From the structural point of view, most devices are simple in structure, only have basic simulation functions, and lack the ability to deeply restore the complex process of geological disasters. For example, when simulating an earthquake, it is only reflected by a simple vibration device, and it is impossible to accurately simulate the propagation characteristics of seismic waves of different magnitudes and different focal depths and the impact on different building structures. In terms of display effect, it is also relatively simple, often simply showing the surface phenomena of the occurrence of disasters, and it is difficult to fully and deeply show the formation mechanism, development process and possible chain reactions of geological disasters. Moreover, the existing devices cannot well simulate the concurrent situations of multiple geological disasters, such as secondary disasters such as landslides and mudslides caused by earthquakes, making it difficult for the audience to have a comprehensive and profound understanding of the complexity and harm of geological disasters.

[0031] Magnetic levitation drive is a motor that uses magnetic suspension technology and electromagnetic force drive technology to achieve linear motion. Its basic principle is to suspend objects in the air through electromagnetic force, eliminate friction and improve efficiency. Specifically, linear magnetic levitation drive mainly relies on the interaction of electromagnetic forces to achieve the suspension and movement of objects. According to the principles of physics, a magnetic field can be applied to a conductor or magnetic material. When the material is placed in a magnetic field, it will be affected by force, thereby producing a suspension effect. The two basic types of magnetic levitation technology include:

[0032] Electromagnetic Suspension (EMS): In an electromagnetic suspension system, the magnetic field generated by the electromagnet interacts with the induced current in the track to allow an object to levitate at a certain height. This technology generally requires a feedback control system to maintain the stability of the suspended object.

[0033] Electrodynamic levitation (EEDS): Using the interaction between superconductors and permanent magnets, objects can be suspended at relatively high altitudes, usually without the need for complex feedback control systems.

[0034] The existing geological disaster model display device includes a mobile base, a support rod is fixed on the mobile base, and a display mechanism is provided on the support rod, which can clearly and intuitively display the process of debris flow generation to the audience. It can intuitively imitate the power and harm of debris flow in natural disasters. It can flexibly display the spatial and attribute information related to the debris flow geological disaster, so that people can more conveniently understand the harm caused by debris flow to human life and property safety, thereby improving the technical effect of the display.

[0035] A display board is fixed on the support rod. The display mechanism includes a simulation component arranged on the display board for simulating debris flow. A wastewater treatment component is arranged on the display board for treating the mud-water mixture after the display is completed. Through the cooperation of the two, the simulation of debris flow and the cleaning after simulation are realized.

[0036] The simulation component includes a connecting rod fixed on the display board, a water tank is fixed on the connecting rod, and multiple nozzles are fixed on the water tank. The display board is rotatably connected to the simulation board through a bearing seat, baffles are fixed on both sides of the simulation board, and an adjusting groove is provided on the display board. A screw rod that rotates through the display board and extends to the outside of the display board at one end is arranged in the adjusting groove, and an adjusting block threadedly sleeved on the screw rod is slidably arranged in the adjusting groove, and a first holding piece is fixed at the end of the screw rod, and a rotating rod is rotatably connected to the adjusting block through the bearing seat, and the end of the rotating rod is rotatably connected to the simulation board. A display groove is provided on the display board. When in use, a house model is placed in the display groove, soil is placed on the simulation board, and then the nozzle is turned on to simulate the rainfall process and generate a mudslide. The harm of the mudslide can be intuitively felt by observing the model in the display groove. When it is necessary to adjust the slope of the simulation board, the first holding piece is rotated to drive the screw rod to rotate, so that the adjusting block moves in the adjusting groove, and then the adjusting block drives the rotating rod to adjust the slope of the simulation board.

[0037] The wastewater treatment component includes a wastewater collection box fixed on a display board, a placement slot is provided at the end of the display slot, slide slots are provided on both sides of the display board, a cleaning plate is provided in the placement slot, guide rods sliding in the slide slots are fixed on both sides of the cleaning plate, a spring is fixed at the end of any guide rod, a connecting column is provided on the side wall of the display board, a rectangular slot is provided in the connecting column, the end of the spring is fixedly connected to the rectangular slot, a second gripping piece is fixed to the end of the connecting column, and at the end of the simulation, the second gripping piece is pulled so that the end of the connecting column no longer presses against the display board, and then it is moved, and the cleaning plate is driven by the guide rod to clean the mud and water mixture in the display slot into the wastewater collection box.

[0038] Another prior art discloses a geological disaster model display device, including a support structure, a vibration structure and a display structure, wherein the display structure is fixedly arranged above the vibration structure, and the support structure is fixedly arranged below the vibration structure. The display structure includes a support bracket, a mounting plate and a glass protective cover, wherein the mounting plate is detachably arranged inside the support bracket, and the glass protective cover is arranged on the mounting plate. A geological disaster model body is arranged inside the glass protective cover, and a sliding nozzle structure is slidably arranged above the glass protective cover, and water can be sprayed at different positions on the model according to the structure of the model. , by spraying water to simulate rainfall, it is possible to simulate geological disasters such as landslides and mud-rock flows caused by local rainfall or large-scale rainfall. Water can be sprayed on different positions of the model through multiple sliding nozzle structures at the same time. The sliding nozzle structure includes a U-shaped clamp and a nozzle. Two U-shaped clamps are provided. The two U-shaped clamps are symmetrically slidably inserted above the glass protective cover. The two ends of the nozzle are respectively fixedly connected to the two U-shaped clamps. A water tank is provided on the support structure. A water pump is provided in the water tank. The output end of the water pump is connected to the top of the nozzle through a hose. A drainage system is provided under the support bracket.

[0039] The above-mentioned existing geological disaster simulation devices only display a single geological disaster, while real geological disasters are often accompanied by multiple geological disasters occurring simultaneously. Therefore, the existing devices do not display a comprehensive and realistic one.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1-Figure 7 As shown, the present invention provides a geological disaster model display device, including: a base 1; a simulated mountain 3, which is fixedly mounted on a support plate 6, and the bottom of the support plate 6 is rotatably connected to the base 1; a magnetic levitation drive component 2, which is mounted on the base 1, and the magnetic levitation drive component 2 is connected to the support plate 6 through a connecting rod 9 and a hinge seat 8, and the inclination angle of the simulated mountain 3 is changed by moving the magnetic levitation drive component 2 on the base 1; a vibration component 4, which is mounted below the support plate 6; a spray component, which is fixedly mounted on a connecting plate 13, and the connecting plate 13 is fixedly connected to the base 1, and the spray component is located above the simulated mountain 3.

[0042] The simulated mountain 3 is used to simulate the topography of the mountain 3, including peaks, valleys, rivers, etc. A spray assembly is arranged above the simulated mountain 3 to simulate the rain scene. The spray assembly can adjust the spray volume to effectively simulate the impact of light rain, heavy rain and rainstorm on geology. A magnetic levitation drive assembly 2 is arranged below the simulated mountain 3. The magnetic levitation drive assembly 2 can conveniently adjust the inclination angle of the simulated mountain 3, which can show the impact of different slopes on geological disasters and the occurrence process of mudslides. A vibration assembly 4 is also arranged below the simulated mountain 3 to simulate the situation during an earthquake. The device can more realistically and effectively show the process of occurrence of different geological disasters.

[0043] like Figure 6 and Figure 7 As shown, a magnetic suspension track 201 is provided on the base 1, and a magnetic suspension drive assembly 2 is installed in the magnetic suspension track 201. The magnetic suspension drive assembly 2 includes multiple groups of electromagnets 202, a magnetic suspension slider 203 and an electromagnetic drive controller. The multiple groups of electromagnets 202 are evenly distributed in the magnetic suspension track 201, and the magnetic suspension slider 203 is located above the electromagnets 202. The electromagnetic drive controller is installed in the magnetic suspension track 201. The electromagnetic drive controller can accurately control the current size and direction of the electromagnets 202, thereby generating a changing magnetic field. The magnetic suspension slider 203 is equipped with a permanent magnet. Under the interaction of the magnetic field, the magnetic suspension slider 203 is located above the multiple groups of electromagnets 202, and does not contact the electromagnets 202 or the magnetic suspension track 201. The magnetic suspension slider 203 can achieve non-contact suspension and movement on the magnetic suspension track 201. This driving method has the advantages of high precision, no friction, and fast response speed. It can more accurately simulate the movement process of objects in geological disasters such as landslides in the mountain body 3, and reduces mechanical wear, thereby improving the service life and stability of the device. The electromagnetic drive controller is electrically connected to the control center. The operator can adjust the operating parameters of the magnetic levitation drive component 2, such as speed, acceleration, etc., through the control center. It can conveniently adjust the inclination angle of the simulated mountain 3 and conveniently simulate the rolling conditions of mudslides on the mountain.

[0044] Limiting grooves 204 are provided on both sides of the magnetic levitation track 201. The magnetic levitation slider 203 is in a T-shaped structure. The top two sides of the magnetic levitation slider 203 are located in the limiting grooves 204. The limiting grooves 204 limit the magnetic levitation slider 203 to prevent the magnetic levitation slider 203 from leaving the magnetic levitation track 201. After the electromagnet 202 is energized to generate a magnetic field, the magnetic levitation slider 203 floats in the magnetic levitation track 201, and the top two sides of the magnetic levitation slider 203 do not contact the limiting grooves 204.

[0045] The top of the magnetic levitation slider 203 is rotatably connected to a connecting rod 9 via a hinge seat 8, and the other end of the connecting rod 9 is rotatably installed under the support plate 6 via the hinge seat 8. The hinge seat 8 connected here is fixedly installed under the support plate 6. The magnetic levitation slider 203 slides in the magnetic levitation track 201 to pull the connecting rod 9 to rotate and drive the support plate 6 to rotate, thereby changing the inclination angle of the simulated mountain 3.

[0046] The bottom of the support plate 6 is installed between two auxiliary plates 12 through a rotating shaft. The auxiliary plate 12 is fixed on the base 1. The bottom of the support plate 6 is rotatably connected to the base 1. An extension plate 10 is fixedly connected to the other side of the support plate 6. A protective box 5 is fixedly installed on both sides above the support plate 6, and a vibration component 4 is installed in the protective box 5.

[0047] like Figure 5 As shown, the vibration assembly 4 includes a cam, a knocking piece 403, a rotating shaft 401 and a motor 404. One end of the rotating shaft 401 passes through the protection box 5 on one side and is rotatably connected to the inner wall of the protection box 5. The other end of the rotating shaft 401 passes through the protection box 5 on the other side and is connected to the output end of the motor 404. The motor 404 is fixedly installed on the outer wall of the protection box 5 on this side. A cam 402 is fixedly connected to the rotating shaft 401. The cam 402 is located in the protection box 5. The knocking piece 403 passes through the protection box 5 and is connected to the support plate 6. The knocking piece 403 is located above the cam 402. During the rotation of the cam 402, the knocking piece 403 intermittently contacts the cam 402, so that the knocking piece 403 intermittently knocks the support plate 6, thereby simulating some conditions on the mountain when an earthquake occurs.

[0048] The knocking piece 403 includes a swinging plate 4031, a second spring 4032 and a hammer head 4033. The swinging plate 4031 passes through the protective box 5. An opening is provided on the protective box 5. The swinging plate 4031 passes through the protective box 5 through the opening. A rotating shaft is installed at the opening. The rotating shaft is installed in the swinging plate 4031. Therefore, the swinging plate 4031 passes through the protective box 5 and is rotatably connected to the side wall of the protective box 5. A hammer head 4033 is installed at one end of the swinging plate 4031. The hammer head 4033 is located below the support plate 6. When the hammer head 4033 moves upward, it contacts the support plate 6 and knocks the support plate 6. A second spring 4032 is installed at the other end of the swinging plate 4031. The top of the second spring 4032 is fixedly connected to the bottom of the support plate 6. The second spring 4032 is located in the protective box 5. The protrusion 402 is located below one end of the swinging plate 4031 where the second spring 4032 is installed. The starting motor 404 drives the rotating shaft 401 and the protrusion 402 to rotate. The protrusion 402 intermittently contacts the swing plate 4031 during the rotation. When the protrusion 402 contacts the swing plate 4031, the end on which the second spring 4032 is installed is lifted upward. At this time, the second spring 4032 is in a compressed state. The protrusion 402 continues to rotate away from the swing plate 4031, and the second spring 4032 stretches, so that the end of the swing plate 4031 on which the second spring 4032 is installed moves downward, and the end on which the hammer head 4033 is installed is tilted. The hammer head 403 3 moves upward to contact the support plate 6 and exert an upward force on the support plate 6, so as to realize the knocking effect on the support plate 6 and the simulated mountain 3 on the support plate 6, the protrusion 402 intermittently contacts the swing plate 4031, so that the hammer head 4033 intermittently knocks the support plate 6, and the frequency of the contact between the protrusion 402 and the swing plate 4031 can be controlled by controlling the motor 404, thereby controlling the frequency of the hammer head 4033 knocking the support plate 6. When the support plate 6 vibrates, the simulated mountain 3 installed on the support plate 6 will also vibrate, thereby realizing a real simulation of an earthquake.

[0049] A first spring 11 is fixedly connected to the extension plate 10, and the top of the first spring 11 is fixedly connected to the spray assembly. The first spring 11 is arranged to play a buffering role when the hammer head 4033 hits the support plate 6, so as to avoid damage to the simulated mountain 3 caused by severe shock.

[0050] The spray assembly includes a mounting plate 14 and a spray head 15. The mounting plate 14 is fixedly connected to the top of the connecting plate 13. The spray heads 15 are evenly distributed on the mounting plate 14. The spray heads 15 are located above the simulated mountain 3 to simulate the scene when it rains.

[0051] A water collecting tank 16 is provided at the bottom of the simulated mountain 3. The water collecting tank 16 is installed on the base 1. A water pumping hole 17 is provided on one side of the water collecting tank 16. A water pipe is connected to the water pumping hole 17. The water pipe runs through the connecting plate 13 and the mounting plate 14 and is connected to the nozzle 15. A water pump is connected to the water pipe. The water pump is located in the base 1, which is convenient for extracting water from the water collecting tank 16 into the water pipe and pumping it to the nozzle 15 along the water pipe. The nozzle 15 adopts an intelligent nozzle 15, which can control the amount of spraying of the nozzle 15 through the control center, and then can simulate light rain, heavy rain and rainstorm, which is convenient for observing the impact on geological disasters under different weather conditions. The water after spraying enters the water collecting tank 16, which is convenient for the recycling of water resources and has the characteristics of saving water.

[0052] The simulated mountain 3 is the core area for displaying geological disasters. It is made of special plastic materials. The surface simulates the topography of the real mountain, including peaks, valleys, rivers, etc. The module is formed by a mold, and the surface has a fine terrain texture, which can simulate the real geological structure. A geological structure layer is set in the simulated mountain 3 to simulate the rock and soil layer structure below the surface. The simulated mountain 3 includes a soil layer 301, a rock layer 302 and a gravel layer 303 laid in sequence. The soil layer 301 is located at the top and uses a mixture of fine sand and humus. Fine sand has good air permeability and certain water permeability, which can simulate the loose structure between soil particles; humus contains certain organic matter, which makes the soil layer 301 have a certain color and texture, which is closer to the appearance of real soil. The volume ratio of fine sand to humus is about 3:1. This ratio can not only ensure the looseness of the soil layer 301, but also give it a certain cohesion, so as to prevent it from being too loose and unable to maintain a certain shape during the process of simulating rainfall.

[0053] The rock layer 302 is located in the middle layer, and a mixture of gypsum and quartz sand is used. After solidification, gypsum has a certain hardness and strength, which can simulate the hardness of rock; the addition of quartz sand can increase the roughness and texture of the rock layer 302, making it closer to the surface characteristics of real rock. The mass ratio of gypsum to quartz sand is about 2:1. During the mixing process, gypsum powder and an appropriate amount of water are first mixed into a slurry in a certain ratio (such as a mass ratio of gypsum powder to water of 1:0.5), and then quartz sand is added and stirred evenly to fully combine.

[0054] The gravel layer 303 is located at the bottom layer and has good water permeability. It is a mixture of natural river sand and small gravel. The natural river sand has uniform particles and good water permeability; the small gravel can increase the porosity of the gravel layer 303, further improving its water permeability, and can also simulate the existence of gravel in the real gravel layer 303. The volume ratio of natural river sand to small gravel is about 2:1. This ratio can ensure that the gravel layer 303 has good water permeability and a certain stability to prevent it from being too loose during the simulation process.

[0055] like Figure 4 As shown, a water pipe 7 is provided below the gravel layer 303, and an opening is provided below the water pipe 7, and a water collecting box 16 corresponds to the opening. In this embodiment, a plurality of water pipes 7 are provided, and the plurality of water pipes 7 are evenly fixed above the support plate 6 to play a role of guiding water, and are used to guide water that passes through the soil layer 301, the rock layer 302 and the gravel layer 303 to the water collecting box 16.

[0056] A water-permeable plate is fixed between the gravel layer 303 and the water pipe 7 to facilitate water permeation and support the gravel layer 303 .

[0058] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
