Description

Technical Field

[0001] This invention relates to the field of fault structure demonstration equipment, and in particular to a magnetic fault structure demonstration device for geological teaching. Background Technology

[0002] In geology teaching, fault structure is one of the important basic teaching contents, involving knowledge points closely related to the basic structure of faults, such as fault types (e.g., normal faults, reverse faults, strike-slip faults), slip distance, and the relationship between the hanging wall and footwall. Currently, in the teaching process, teachers usually use static models, pictures, or animations to explain fault structure.

[0003] However, existing static models are mostly fixed structures, unable to dynamically demonstrate the formation process of faults. Students can only passively observe, lacking interactive experience and finding it difficult to deeply understand the movement relationships of different parts of a fault structure. While pictures and animations can show the dynamic process, students cannot operate them themselves, resulting in a less intuitive perception of the spatial structure of faults and a less profound understanding of the stress background of fault formation, leading to poor learning outcomes. In addition, some existing demonstration devices are complex in structure, inconvenient to carry, and expensive, making it difficult to flexibly combine and demonstrate different types of fault structures according to teaching needs.

[0004] Therefore, a magnetic attraction demonstration device for fault structures is proposed for geological teaching. Summary of the Invention

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.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-4 This invention provides a magnetic demonstration device for fault structures used in geological teaching, comprising: Base 1, with permanent magnet 2 inside; The fault plate has several fault plates. A first magnetic block 3 is installed at the bottom of the fault plate. A second magnetic block 10 is built into the fault plate. The first magnetic block 3 is magnetically connected to the permanent magnet 2. The auxiliary measurement component includes a scale 4, an inclination measuring device 5, and a storage box 6. Both the base 1 and the fault plate are detachably connected to the storage box 6. The scale 4 is located on the top surface of the base 1. The inclination measuring device 5 is used to measure the inclination angle of the fault fracture surface of the fault plate. The scale 4 uses graduation lines or a ruler to accurately measure the fault displacement. The inclination measuring device 5 uses a compass, a laser inclinometer, or an electronic inclination sensor. Among them, the fault plate is marked with mark 7; With this setup, the present invention achieves flexible splicing and dislocation simulation of fault plates by using the attraction or repulsion of the second magnetic block 10 built into the fault plate. Students can apply external force to push the fault plate to move on the base 1. Through the fault plate, the formation process of different types of faults such as normal faults and reverse faults and different stress environments are simulated. The macroscopic geological movement is transformed into an operable and concrete experience, which significantly improves the depth of understanding of fault structure, changes passive observation to active operation, and enhances the interactivity and depth of understanding in teaching.

[0025] This invention demonstrates multiple fault types, including normal faults, reverse faults, and strike-slip faults, by replacing fault plates, enhancing teaching flexibility and adaptability to meet the needs of different teaching content. Compared to traditional models with fixed structures, it eliminates the need to purchase multiple sets of equipment to cover diverse teaching scenarios, significantly improving equipment utilization. The device features a convenient storage box for quick assembly, preventing component wear or loss during transport and adapting to various teaching environments such as outdoor, indoor, and laboratory settings.

[0026] This invention measures key parameters such as fault displacement and the inclination angle of fault surfaces using calibration and dip measurement equipment, upgrading qualitative demonstrations to quantitative analysis. This allows students to master geological surveying methods through hands-on practice, extending teaching content from conceptual explanation to practical application, cultivating scientific inquiry abilities, and enriching the functionality and scientific rigor of teaching. Furthermore, the fault plates in this invention can visually display lithological differences, and supplement stratigraphic age information through markings, forming a multi-dimensional teaching system. This helps students build a complete geological knowledge network and improves the effectiveness of demonstrations.

[0027] This invention employs magnetic connections to avoid the risk of pinching fingers associated with traditional snap-fit ​​structures, fully considering the safety of student operation and making it suitable for group use in classrooms or small group experiments. The magnetic connection eliminates the need for complex operations when splicing and fixing fault plates, improving demonstration efficiency. This invention overcomes the limitations of traditional static demonstrations, enabling dynamic simulation of fault structures, interactive operation, and tilt measurement. It features a simple structure, convenient operation, and high practicality for teaching.

[0028] The design has been further optimized by installing an anti-slip structure on the bottom of base 1.

[0029] The scheme is further optimized. The fault plate includes a connecting seat 8 and a fault structure model 9. The fault structure model 9 is detachably connected to the bottom of the connecting seat 8. The connecting seat 8 is slidably connected to the top surface of the base 1. The first magnetic block 3 is installed at the bottom of the connecting seat 8. There are two second magnetic blocks 10, which are respectively embedded on the two opposite cross-sections of the fault structure model 9. When demonstrating a normal fault, the two second magnetic blocks 10 use magnets of the same polarity. When demonstrating a reverse fault and a strike-slip fault, the two second magnetic blocks 10 use magnets of opposite polarity. The fault structure model 9 includes several plate units, which are detachably connected. The first magnetic block 3 at the bottom of the connecting seat 8 is attracted to the permanent magnet 2 inside the base 1, achieving a stable connection with the base 1 and allowing it to slide on the top surface of the base 1. When different types of faults or stratigraphic structures need to be demonstrated, students can quickly replace the fault structure model 9 by disassembling and reassembling the plate units, replacing the normal fault plate unit with the reverse fault plate unit; they can also change the combination of the connecting seat 8 with different fault structure models 9 to flexibly adjust the demonstration content. This modular design not only reduces the maintenance cost of the device but also meets diverse teaching needs through different combinations, improving the scalability of the device.

[0030] Several plate units are used to simulate the layered structure of different lithological strata. The layers have different colors and textures to distinguish different lithologies such as Quaternary strata, sedimentary rocks, igneous rocks, and metamorphic rocks. For example, Quaternary strata are yellow, sedimentary rocks are blue, igneous rocks are red, and metamorphic rocks are purple. The edges of the fault plates have dip surfaces corresponding to the fault fracture surfaces. The angle of the dip surfaces can be adjusted according to the fault type. For example, the dip surface angle of normal faults is generally steeper and can be designed to be 45°-60°, the dip surface angle of reverse faults is relatively gentler, and in this embodiment it is 30°-45°, and the dip surface angle of strike-slip faults is the steepest and can be set to 70°-90°.

[0031] Further optimization of the design resulted in both the connecting seat 8 and the fault structure model 9 being made of lightweight, rigid materials, including but not limited to ABS plastic. Using transparent, lightweight, and rigid materials such as ABS plastic reduces weight while maintaining structural strength. The lightweight nature lowers the risk of accidental injury from component collisions during student operation. For example, even if a collision occurs when students are assembling or moving fault plates, the impact force generated by the lightweight components is smaller. The rigid materials ensure that the components are not easily deformed, maintaining structural integrity during frequent disassembly, assembly, and simulated movements. This guarantees the accuracy and demonstration effect of the fault structure simulation, extends the device's lifespan, and also makes it easier for students to handle, operate, and store.

[0032] The design has been further optimized. Base 1 adopts a cuboid structure with chamfered edges. Base 1 can be made of wood, plastic, or non-magnetic metal, or a combination of these materials. The cuboid shape ensures stability and prevents tipping; the chamfered edges eliminate sharp corners, preventing accidental bumps and injuries to students during operation and improving safety. The choice of wood, plastic, or non-magnetic metal for base 1 is advantageous. Wood and plastic are low-cost and lightweight, facilitating transport and installation; non-magnetic metal ensures the magnetic force of the internal permanent magnet 2 remains undisturbed, guaranteeing stable magnetic attraction with the fractured plate. All component edges are smoothed to further reduce the risk of scratches and comprehensively ensure student safety during operation.

[0033] The design has been further optimized, with a handle 11 installed on storage box 6.

[0034] The design is further optimized by providing a first slot, several second slots, and several third slots inside the storage box 6. The base 1 is engaged with the first slot, several connecting seats 8 are engaged with several second slots, and several fault structure models 9 are engaged with several third slots. The handle 11 on the storage box 6 makes it easy for teachers or students to carry the device, allowing it to be flexibly applied to different teaching scenarios. The first, second, and third slots inside the box correspond to the shapes and sizes of the base 1, connecting seat 8, and fault structure model 9, respectively, securing each component in place via snap-fit ​​mechanisms. This partitioned storage design prevents components from colliding, wearing down, or being lost during transport. For example, the connecting seat 8 and fault structure model 9 are fixed in their respective slots, preventing damage to the second magnetic block 10 due to shaking. Simultaneously, the slot positioning makes assembly more convenient, allowing teachers or students to quickly remove and accurately install each component, saving preparation time and improving demonstration efficiency.

[0035] The design has been further optimized, and fluorescent markings have been adopted for marking 7. Label 7 includes text labels that directly annotate core fault structure terms such as "hanging wall," "footwall," "fault displacement," and "fault surface," helping students quickly identify and memorize the names and definitions of different parts of a fault, thus strengthening their understanding of the knowledge points. It also includes arrow labels that visually demonstrate the direction of movement of one side of the fault, allowing students to clearly understand the displacement trends of plates in different types of faults and comprehend the kinematic characteristics of faults. Furthermore, it includes symbol labels that provide additional geological information such as stratigraphic age and lithology, enriching the demonstration content and helping students build a more complete geological knowledge system to understand the entire process of fault dislocation and stratification.

[0036] In dimly lit teaching environments (such as when the main classroom light is off while using a projector to display a PowerPoint presentation), the fluorescent material absorbs ambient light and slowly releases it, causing the marker 7 to glow continuously and clearly display information such as stratigraphic age and lithology. Students can see the marker content without needing to get close to the device, making it easier for teachers to combine with different lighting conditions for diverse teaching methods. For example, when explaining nighttime geological phenomena or simulating stratigraphic changes through light and shadow effects, the fluorescent marker can help students better understand geological knowledge, enhancing the teaching interest and the effectiveness of information delivery.

[0037] Further optimization of the design includes an anti-slip structure comprising several legs 12, which are fixedly installed at the four corners of the bottom of the base 1. Anti-slip pads 13 are installed on the bottom of each leg 12. The legs 12 support and raise the base 1, creating a gap between the base 1 and the surface, reducing the direct friction area between the base 1 and the surface. Simultaneously, the four legs 12 distribute the weight of the device, enhancing stability. The anti-slip pads 13 are made of a high-friction coefficient material (such as rubber), with a rough surface and a certain degree of elasticity. When in close contact with the surface, they effectively increase friction, preventing the device from sliding due to force during the student's simulation of geological movement by pushing fault plates. This ensures the device remains in place during the demonstration, improving operational safety and demonstration accuracy.

[0038] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
