Description

Technical Field

[0001] This utility model relates to the field of earthquake science and education equipment technology, specifically a multi-layer earthquake simulation experience platform. Background Technology

[0002] Earthquake disasters refer to the strong ground vibrations caused by earthquakes, along with associated ground cracks and deformations, leading to the collapse and damage of various buildings, equipment and facilities, disruption of transportation and communication, and destruction of other lifeline engineering facilities. They also include secondary disasters such as fires, explosions, epidemics, leaks of toxic substances, radioactive contamination, and site damage, causing injury and death to people and livestock and property loss. Earthquakes can be classified according to their causes into collapse earthquakes, impact earthquakes, volcanic earthquakes, and tectonic earthquakes. More than 90% of these are tectonic earthquakes, which are vibrations of the Earth's surface caused by tectonic movements within the Earth. These vibrations are the most intense and cause the most severe damage to human civilization.

[0003] To better understand the dangers of earthquakes, popularize emergency avoidance methods during earthquakes, and teach self-rescue and mutual rescue skills when trapped during an earthquake, an earthquake safety education simulation platform was designed. However, existing platforms are mainly small-scale single-layer platforms with limited load-bearing capacity. They are mainly used to perceive earthquake shaking of different levels, but lack practical training in earthquake avoidance skills. Furthermore, the platform scene construction is relatively simple, and the immersive environment is not good. Therefore, this needs to be addressed urgently. Utility Model Content

[0017] This earthquake training platform is a two-layer structure. The underground section is a six-degree-of-freedom hydraulic motion platform capable of simulating the combined action of P-waves and S-waves, maximizing the simulated intensity. The above-ground section realistically recreates the structural components of a high-rise building, employing different structural designs on each floor to simulate varying levels of vibration. This allows participants to perceive the "structural amplification effect" of building structures on seismic wave amplitude, thus deepening their understanding of the importance of earthquake resistance and safety in high-rise buildings, and also increasing the number of participants. The interior features a realistically constructed residential home scene, surrounded by immersive multimedia that simulates the outdoor environment before and after an earthquake, providing a more visually immersive experience. Simultaneously, video capture and infrared sensing work together to capture the participants' movements and identify their positions under intense vibrations, determining whether their evacuation methods are correct, disseminating information on indoor earthquake preparedness methods and common misconceptions, and emphasizing the importance of mastering proper safety skills. Participants can alternate between the two floors. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 In this embodiment of the utility model, a multi-layer earthquake simulation experience platform simulates the state of a high-rise building when it encounters an earthquake by simulating the construction of a real two-layer earthquake building 2. It uses immersive multimedia, mechanical devices, video cameras, infrared sensors, lights, etc. to simulate the state before, during, and after the earthquake.

[0024] A commonly used six-degree-of-freedom hydraulic motion platform 1 consists of six electric cylinders 12, a base 11, a support plate 13, and six Hooke hinges on both the upper and lower parts of the platform. The base 11 is fixed to the infrastructure. The extension and retraction of the six electric cylinders 12 controls the movement of the support plate 13 in six degrees of freedom (X, Y, Z, α, β, γ) in three-dimensional space, thereby simulating various spatial motion postures. The electric cylinders 12 of the six-degree-of-freedom hydraulic motion platform 1 are connected to the upper and lower platforms using high-rigidity Hooke hinges, resulting in smooth and stable movement, high rigidity, high strength, and maintenance-free operation.

[0025] The double-layer earthquake-resistant building 2 includes a cuboid frame 21 formed by multiple horizontal bars 22 and multiple vertical bars 23 that are interlocked and fixed together. Diagonal bars 24 are arranged in the grid formed by the interlocking horizontal bars 22 and vertical bars 23, and the diagonal bars 24 are arranged on the diagonal of the grid to divide the grid into two triangles, thereby improving the overall support strength of the frame 21 and preventing damage during the demonstration.

[0026] Multiple wall panels 25 are fixed to the frame 21. These panels cooperate to form a box with a door. The interior of the box is divided into upper and lower floors by partitions, forming the first and second floors, which are connected by a staircase. To further enhance the safety of participants during the demonstration, all furniture on both the first and second floors is fixed in place to prevent it from moving and injuring them. Additionally, stainless steel handrails 27 and uprights 26 are installed on the wall panels 25 on both the first and second floors to provide support during vibrations. These uprights 26 are arranged sequentially in areas not occupied by furniture, vertically penetrating the partitions and supporting the box, thus improving the structural stability of the box and providing additional support points for participants.

[0027] The handrail 27 is U-shaped, with both ends fixed to the wall panel 25, and is arranged diagonally along the wall to facilitate users of different heights to find support in different positions.

[0028] To begin your experience, before entering the double-layer earthquake building 2, you can see an electronic screen in front of the building playing earthquake science information on a loop, allowing you to anticipate the magnitude of the earthquake after entering the double-layer earthquake building 2.

[0029] After entering the two-story earthquake-prone building 2, participants can choose to experience either the living room area on the first floor or the bedroom area on the second floor. Each space has two windows, and multimedia display screens are located outside the windows. During the experience, the screens simultaneously display images of the view outside the windows before, during, and after the earthquake, along with lighting and sound effects, creating an immersive experience of the earthquake's occurrence.

[0030] After all participants have selected and are in their designated positions, the earthquake platform is activated, and the six-degree-of-freedom hydraulic motion platform 1 begins to move. Through the regular movement of the six-degree-of-freedom hydraulic motion platform 1, participants experience the impact of an earthquake.

[0031] After the earthquake, participants quickly found nearby shelter and took appropriate protective actions. They grabbed onto nearby fixed objects such as handrails (27), pillars (26), or tables and chairs. Correct shelter areas were set up on both floors. For example, on the first floor, participants could hold onto the table legs under a dining table, or quickly lie down next to low, sturdy furniture like a sofa, or use sofa cushions to protect their heads and hide in a triangular safety zone like a corner. It was important to minimize the area of ​​contact with the body. On the second floor, participants in bedrooms could hide under the bed or in the triangular area formed by the wardrobe and the wall, again holding onto fixed objects to prevent displacement and protecting their head and neck.

[0032] Synchronous cameras capture data in real time using optical motion capture technology and machine vision to detect the XY coordinates of key human body points. These key points describe the skeletal structure of the human body, and changes in positional information predict human posture, thus completing motion capture and recognizing key earthquake avoidance actions such as "lying down" and "grasping." A multi-camera 3D spatial positioning method identifies individual locations within a pre-defined 3D scene, labeling them as danger or safe zones. Infrared sensors further verify the designated areas, determining whether the participant's sheltering position is correct.

[0033] After the experience, all components were restored to their initial state. Participants watched a video recording of the entire sensory experience, and professionals explained the various avoidance methods shown in the video, educating the participants.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
