Earthquake alarm demonstration instrument for science popularization

Abstract

The invention discloses an earthquake alarm demonstration instrument for science popularization, and the instrument comprises a base 1, wherein two layers of panels 3 are supported in the middle of the base 1 through four springs 8, and screw rods 20 are arranged in the springs 8; motor assembling and disassembling holes 2 at different positions are formed in the base 1 and located below the two layers of panels 3, a motor 13 is installed in the motor assembling and disassembling hole 2 at a certain position, a rolling bearing 14 is installed on an output shaft of the motor 13, and a vibratingreed 15 is installed on the rolling bearing 14; graduated scales 11 are arranged on the peripheral edges of the two layers of panels 3; and the two layers of panels 3 are provided with induction metal ball initial retention circular grooves 12. The instrument can be used as an alarm device, can also be used for demonstration, and can also be used for researching and analyzing the vibration trackof an object. When a simulated earthquake occurs, an alarm is given immediately, so the loss degree when the earthquake occurs is reduced, the convenience and lightness are achieved, the demonstrationfunctions are diversified, the earthquake alarm is convenient to use in a school earthquake science popularization room and an earthquake science popularization museum, the earthquake alarm principleis better popularized, and national disaster prevention and reduction consciousness is improved.

Description

technical field [0001] The invention relates to the field of earthquake alarm demonstration, in particular to an artificial earthquake alarm demonstration instrument, which is suitable for popular science education. Background technique [0002] my country is one of the countries in the world with particularly serious earthquake disasters due to its vast territory and complex structure of the seismic belt, which is located between the circum-Pacific seismic belt and the Eurasian seismic belt. Each earthquake series has certain characteristics, and they have certain regularities in magnitude difference, distance difference, time difference, focal depth difference and so on. In terms of trajectory shape, some are geometric figures such as arcs, oblique lines, and straight lines. [0003] With the advancement of science and technology, the development of society, and the improvement of people's living standards, the attention of all walks of life to the principle of earthquake...

AI Technical Summary

Problems solved by technology

However, the currently used demonstration instruments are all bulky and large-scale equipment, and there is no relatively small earthquake demonstration instrument

In addition, the widely used earthquake demonstration instruments have single functions, complex structures, professional operation, and low penetration rate, so they cannot demonstrate the earthquake process to people simply and clearly.
