[0002] Earthquakes are a common natural disaster, causing immense damage and loss to human society. To enhance public awareness and understanding of earthquakes, models are often used to scientifically demonstrate earthquakes. Demonstrating the movement of tectonic plates is a key method for depicting earthquakes.

[0003] The technical solution disclosed in the patent document entitled "A Simulated Normal and Reverse Fault Demonstrator" (document number CN221529353U) includes a base plate and a demonstration platform. The demonstration platform is arranged on the base plate, and an opening is provided on the top of the demonstration platform. A normal fault model and a reverse fault model are respectively provided at the opening of the demonstration platform. A driving mechanism for controlling the movement of the normal fault model and the reverse fault model is provided inside the demonstration platform, and a display mechanism is provided on the base plate. Through the coordination of normal fault simulation, reverse fault model, driving mechanism and display mechanism, this solution can simulate the movement process of normal faults and reverse faults, the deformation of the earth's crust, etc.

[0004] The movement of crustal plates during an earthquake includes convergence-type plate movement, rift-type plate movement, and slip-type plate movement. The above technical solution only shows the changes in the form of normal and reverse faults. The display of the movement of crustal plates is too simple, which is not conducive to visitors' comprehensive understanding of the different movement forms of crustal plates, so it needs to be improved. Summary of the Invention

[0008] The said crack type plate motion display unit comprises a first crack type simulation plate and a second crack type simulation plate arranged front and back relative to each other, and the second driving unit drives the first crack type simulation plate or the second crack type simulation plate to move back and forth horizontally;

[0009] The displaced plate motion display unit includes a first displaced simulation plate and a second displaced simulation plate arranged relative to each other in the front and back directions.

[0020] The following is combined with Figure 1-9 And related content, the utility model is further described in detail:

[0021] An earthquake demonstration model, wherein a display stand 10 is provided with a convergent plate movement display unit 11, a rift plate movement display unit 12, and a dislocation plate movement display unit 13. It should be noted that the definition of direction in this application is based on the direction in which visitors normally face when viewing the model, such as Figure 1As shown, the K direction is the direction in which visitors normally observe the model. The side of the model closest to the visitor is the front, and the opposite side is the back. Figure 3 、 Figure 4 as well as Figure 7 As shown, each display unit is introduced separately.

[0022] First, the convergent plate motion display unit 11 includes a first convergent simulated plate 111, adjacent to a second convergent simulated plate 112. A first drive unit 21 drives either the first convergent simulated plate 111 or the second convergent simulated plate 112 to move obliquely, at an angle to the horizontal. In this type of plate motion, two plates move relative to each other, with one plate sinking into the Earth's interior, forming a subduction zone, while the other plate is squeezed.

[0023] Secondly, the rift-type plate motion display unit 12 includes a first rift-type simulated plate 121 and a second rift-type simulated plate 122 arranged in a front-to-rear relationship. The second drive unit 22 drives the first rift-type simulated plate 121 or the second rift-type simulated plate 122 to move horizontally forward and backward. In this type of plate motion, the two plates move apart or closer to each other.

[0024] Third, the shifting plate motion display unit 13 includes a first shifting simulated plate 131 and a second shifting simulated plate 132 arranged in a front-to-rear relationship. The third drive unit 23 drives the first shifting simulated plate 131 or the second shifting simulated plate 132 to move horizontally. In this type of plate motion, the two plates slide relative to each other.

[0025] In the above overall scheme, the display stand 10 is equipped with an aggregation type plate movement display unit 11, a rift type plate movement display unit 12 and a dislocation type plate movement display unit 13. The driving unit can drive the simulated plates in each display unit to simulate different movement forms of the crustal plates, so that visitors can have a more comprehensive understanding of the principles of different forms of crustal plate movement, which increases the richness and diversity of the overall demonstration effect of the model.

[0026] Furthermore, the display stand 10 is internally provided with a first control chamber 10A, a second control chamber 10B, and a third control chamber 10C corresponding to the convergent plate motion display unit 11, the rupture plate motion display unit 12, and the shifting plate motion display unit 13, respectively. The first drive unit 21 is located in the first control chamber 10A, the second drive unit 22 is located in the second control chamber 10B, and the third drive unit 23 is located in the third control chamber 10C. The placement of each drive unit within the corresponding control chamber within the display stand 10 enhances the overall model's appearance and aesthetics. The display stand 10 is provided with corresponding plate placement holes 14 for accommodating each simulated plate.

[0027] As a preferred solution, the first control chamber 10A is provided with a screw mechanism 40 whose rod core direction is obliquely arranged at an angle to the horizontal plane. The screw mechanism 40 in the first control chamber 10A drives the first aggregate type simulation plate 111 or the second aggregate type simulation plate 112 to make an oblique displacement along the rod core direction of the screw mechanism 40; the second control chamber 10B is provided with a screw mechanism 40 whose rod core direction is located in the front-back horizontal direction. The screw mechanism 40 in the second control chamber 10B drives the first crack type simulation plate 121 or the second crack type simulation plate 122 to make a front-back horizontal displacement; the third control chamber 10C is provided with a screw mechanism 40 whose rod core direction is located in the left-right horizontal direction. The screw mechanism 40 in the third control chamber 10C drives the first shift type simulation plate 131 or the second shift type simulation plate 132 to make a left-right horizontal displacement. In this solution, each simulation plate is driven to move by a screw mechanism 40, which drives the corresponding simulation plate to move along the rod core direction of the screw mechanism 40, so that the corresponding simulation plate simulates the movement of the crustal plate.

[0028] Combine Figure 6 and Figure 7 As shown, in order to better simulate the movement of crustal plates, the two opposing simulation plates in each display unit can be driven and displaced by independent screw mechanisms 40, thereby demonstrating the respective movement changes between the two opposing plates. To this end, two screw mechanisms 40 are arranged with parallel rod core directions in the first control room 10A, the second control room 10B, and the third control room 10C. The two screw mechanisms 40 in the first control room 10A respectively drive the first aggregated simulation plate 111 and the second aggregated simulation plate 112 to make oblique displacements; the two screw mechanisms 40 in the second control room 10B respectively drive the first cleavage simulation plate 121 and the second cleavage simulation plate 122 to make horizontal displacements in the front-to-back direction; and the two screw mechanisms 40 in the third control room 10C respectively drive the first shifted simulation plate 131 and the second shifted simulation plate 132 to make horizontal displacements in the left-to-right direction. Each simulation plate is driven by a separate screw mechanism 40. Corresponding brackets can be set up in different control rooms to provide installation locations for the screw mechanisms 40.

[0029] Further integration Figure 8 As shown, the screw mechanism 40 includes a guide rail 41, on which a nut slider 42 is arranged to form a guide and limiter. A motor 43 on the guide rail 41 drives a screw 44 arranged parallel to the length of the guide rail 41. The nut slider 42, which is threadedly engaged with the screw 44, is connected to the corresponding simulation plate. The screw mechanism 40 is a linear motion mechanism. It uses the motor 43 to drive the screw 44 to rotate, causing the nut slider 42 to move along the guide rail 41, thereby driving the simulation plate connected to the nut slider 42 to move.

[0030] As shown in the accompanying drawings, in the present application, a control panel 15 is provided at the front end of the display stand 10. The control panel 15 is provided with first, second, third, fourth, and fifth push rods 151a, 151b, 151c, 151d, and 151e, respectively. The first push rod 151a and the second push rod 151b are respectively used to control the movement of the two screw mechanisms 40 in the first control chamber 10A. The third push rod 151c and the fourth push rod 151d are respectively used to control the movement of the two screw mechanisms 40 in the second control chamber 10B. The fifth push rod 151e is used to control the movement of the two screw mechanisms 40 in the third control chamber 10C. By providing each push rod, visitors can control the movement of the corresponding simulation plate by operating the corresponding push rod, thereby causing the corresponding display unit to simulate the movement of the crustal plate, thereby enhancing the interactivity between the model and visitors. At the same time, multiple people can interact simultaneously, so that the demonstration effect of the model can be optimized.

[0031] Furthermore, the lower ends of the first, second, third, fourth and fifth hand push rods 151a, 151b, 151c, 151d and 151e are all connected to a slide 152, and the interior of the control panel 15 is provided with a slide rail 153 that corresponds to each slide 152 one by one and constitutes a guide limit fit. Both ends of the slide rail 153 are provided with a travel proximity switch, and the travel proximity switch is connected to the control circuit of the motor 43 of the corresponding screw mechanism 40. When the slide 152 is located at the travel proximity switch position at both ends of the slide rail 153, the motor 43 drives the screw 44 to rotate forward or reverse. In this solution, by setting travel proximity switches at both ends of the slide rail 153, when the hand push rod is controlled to move horizontally, the slide 152 slides on the corresponding slide rail 153 with the hand push rod. When the slide 152 moves to the travel proximity switch position at one end of the slide rail 153, the control circuit of the motor 43 of the corresponding screw mechanism 40 is started, and the motor 43 drives the corresponding simulation plate to perform corresponding displacement movement. When the hand push rod is pushed in the reverse direction, when the slide 152 moves to the travel proximity switch position at the other end of the slide rail 153, the motor 43 drives the corresponding simulation plate to move in the reverse direction, thereby controlling the simulation plate to simulate the movement of the crustal plate or reset to the initial position.

[0032] It should be noted that, in the present application, two push rods are provided for the aggregation type plate motion display unit 11 and the crack type plate motion display unit 12 to respectively control the independent movement of the two relative simulation plates, while for the shift type plate motion display unit 13, one push rod (i.e., the fifth push rod 151e) is provided to control the simultaneous movement of the two relative simulation plates. When the fifth push rod 151e is controlled to move to the left or right, the corresponding slide 152 can be moved to the two relative stroke proximity switch positions on the slide rail 153, and the first shift type simulation plate 131 and the second shift type simulation plate 132 will make synchronous reverse displacements in the left and right horizontal directions. As for whether the fifth push rod 151e moves to the left or right, it is to control the displacement of the first shift type simulation plate 131 or the second shift type simulation plate 132 to the left or right. When the fifth push rod 151e is controlled to move and the connected slide 152 moves to the middle position of the corresponding slide rail 153, the first and second shift-type simulation panels 131 and 132 move to their initial positions facing each other.

[0033] As a preferred solution, to protect the simulated panels from direct contact with visitors and prevent damage, a transparent protective cover 30 is provided on the display stand 10. Each simulated panel is positioned within the protective cover 30, effectively protecting the simulated panels. The protective cover 30 can be provided separately for each display unit, or a single large protective cover 30 can be provided to uniformly protect all display units.
