Description

TECHNICAL FIELD

[0001] The utility model relates to a demonstration simulation sand cabinet, concretely relates to a geological disaster demonstration simulation sand cabinet, belongs to the technical field of geological disaster simulation and popular science operation demonstration. BACKGROUND

[0002] Geological disasters refer to geological actions or geological phenomena caused by natural or human factors, which cause loss of human life and property and damage to the environment, such as landslides, collapses, debris flows, ground subsidence, and ground fissures.

[0003] China is one of the countries most severely affected by geological disasters in the world, with a wide distribution, multiple types of disasters, and high frequency of occurrence, causing serious loss of life and property of the people every year. Among the numerous geological disasters, loose layer landslides and collapses are the most common disaster types in mountainous areas, posing the greatest threat to people's life and property and causing the greatest loss. (Both have some common characteristics, and there is no clear distinction standard in reality, so they are collectively referred to as "landslides" below.) However, people's understanding or recognition of landslides is very limited, and most people lack direct understanding of the precursory phenomena and disaster process of field landslides. Lack of correct understanding of disaster phenomena leads to failure to correctly identify and reasonably avoid geological disasters, resulting in unnecessary losses.

[0004] Although we often see posters, texts, and animated film and television propaganda about geological disaster risk prevention and disaster reduction through television broadcast programs, popular science books, disaster prevention and reduction days, and Earth Day activities, but often due to lack of firsthand experience and related practice, it still remains at the level of conceptual and imaginal understanding, especially minors and those who have not experienced it cannot truly understand what a landslide is.

[0005] Currently, in addition to pictures, animations, and videos to display landslide disasters and popularize disaster prevention knowledge, there is no setting that allows the audience to participate in the geological disaster process in an immersive manner.

[0006] The patent technology solutions or models related to geological disasters that have been applied can be roughly divided into two categories, but neither can solve the above-mentioned practical problems.

[0007] The first category is a sand table model display, similar to a geographical landscape sand table, which can only be viewed statically and cannot be interacted with or operated manually. For example,

[0008] A scenic spot geological popular science education sand table (CN220491484U), a hall demonstration simulation sand table (CN219750578U), etc.

[0009] The second category is a professional simulation experiment, which mainly provides demonstration simulation devices for college students and related professional researchers, requiring certain professional knowledge and complex operation. For example,

[0010] A geological disaster model display (CN213877256U, CN217444014U) discloses a display and simulation of earthquake geological disasters and the risk of earthquake waves causing disasters.

[0011] A teaching demonstration device for landslides (CN113409669A) discloses a teaching device for simulating and demonstrating landslides caused by various conditions.

[0012] A landslide model test box (CN218995358U) improves the slope and rain control of the existing landslide model test box.

[0013] In addition, there is another type of device that uses VR technology to immerse in natural disasters, which has high cost and lacks realism and participation.

[0014] Therefore, on the basis of people's (especially teenagers') understanding of landslide geological disasters, it is necessary to provide a loose layer (including rock-soil interface) landslide disaster demonstration simulation sand cabinet that can deepen the understanding of landslide disasters through hands-on operation and on-site observation, and can enhance the ability to avoid risks and prevent disasters. In the operation process, the unity of geological disaster recognition-practice-re-recognition is realized, and the disaster prevention consciousness and concept become a personal accomplishment reserve in the body. When similar phenomena occur in mountainous areas, it can quickly be converted into disaster prevention ability and risk avoidance action. At the same time, this device can also provide preliminary simulation and teaching demonstration for professional simulation research. SUMMARY
