Miniature seismic platform

Abstract

The invention provides a miniature seismic platform, which is divided into three layers, including a bottom frame 9, a middle frame 5 and an upper frame 1, wherein the upper plane of the bottom frame 9 is connected with the lower plane of the middle frame 5 through two groups of linear bearing assemblies 8, the upper plane of the middle frame 5 is connected with the lower plane of the upper frame 1 through four groups of energy accumulator sliding column assemblies 4 and an eccentric connecting rod 2 via a longitudinal wave speed changing motor 3, and four rubber feet 10 are fixed to the lower plane of the bottom frame 9. The miniature seismic platform has the advantages of simple structure, convenient maintenance, simple operation, compact structure, small occupied area and low cost, can be operated by a person clear about functions of all buttons without advanced scientific and technological knowledge, is suitable for groups from all sectors of society, has no special requirement on demonstration environment, and only needs flat ground surface, smooth wall and a 220V power supply.

Description

technical field [0001] The invention belongs to a seismic platform, more precisely a miniature seismic platform for popularization and education. Background technique [0002] Since the Wenchuan earthquake in Sichuan on May 12, 2008, various forms of earthquake knowledge popularization and education have sprung up in popular science museums, science palaces, science and technology museums, children's palaces, and major and technical secondary schools all over the country. Its seismic platform was the main demonstration project. Since the popularization and education of earthquake knowledge focused on the above-mentioned units at that time, the visitors and students came from all walks of life, the flow of people was large, and most of the seismic platforms were small and medium-sized. Such platforms were not only expensive but also occupied a large area Its structure is complex, it has high requirements for operators, it must have certain professional knowledge, and it has s...

Its seismic platform was the main demonstration project. Since the popularization and education of earthquake knowledge focused on the above-mentioned units at that time, the visitors and students came from all walks of life, the flow of people was large, and most of the seismic platforms were small and medium-sized. Such platforms were not only expensive but also occupied a large area. Its structure is complex, it has high requirements for operators, it must have certain professional knowledge, and it has strict requirements for the placement environment.
