Description

Technical Field

[0001] The utility model belongs to the field of disaster simulation, and specifically relates to an earthquake simulation device. Background Art

[0002] Earthquakes are unpredictable and extremely destructive, so people need to understand the dangers of earthquakes. Since modern society advocates universal education on protecting personal safety, simulated earthquake facilities are often exhibited in various places so that more people can experience, understand and learn the knowledge of preventing earthquake damage.

[0003] A Chinese patent with publication number CN216083988U discloses an earthquake simulation device, including a fixed platform, an adjustment mechanism and a base. The top of the fixed platform is equipped with an adjustment mechanism, and the adjustment mechanism is composed of a fixed plate, an electric telescopic rod A, a speed regulator, an electric telescopic rod B, a beam photoelectric sensor A and a beam photoelectric sensor B. The outer wall of the fixed plate is equipped with an electric telescopic rod A, and the output end of the electric telescopic rod A is equipped with a beam photoelectric sensor A. The outer wall of the fixed plate is equipped with an electric telescopic rod B, and the output end of the electric telescopic rod B is equipped with a beam photoelectric sensor B.
