Multistage amplification swinging type omnibearing earthquake impending alarm

Abstract

The invention relates to a multistage amplification swinging type omnidirectional impending earthquake alarm, which can generate an alarm in the situation that the ground starts to slightly swing before the impending earthquake in a mechanical multistage amplification manner. The alarm is composed of a machine outer casing and a lower base seat, a machine internal part device frame, a X-shaped base seat connected under the device frame and used for increasing the swinging, a plurality of groups of two-stage amplification swinging soft spring supporting frames and soft spring swinging contact head balls arranged on the device frame, a plurality of groups of circuit contact heads, a plurality of groups of circuit contractors, an alarm generator, a battery pack and a transformer, etc. The device is characterized in that the stratum slightly swings when a large earthquake impends, the alarm enables the swinging to be increased through three-stage physical transfer, automatic alarm is realized through closing a swing triggering alarm circuit after being enlarged, so as to remind the people to avoid immediately. The alarm has the advantages that the alarm is amplified by adopting the physical principle, and is fearless of being moistened; the service life of the alarm is longer; an amplification swing device is arranged aiming at five directions of left, right, front, rear and underground; an impending earthquake slight swinging wave from different directions can be detected; and the alarm scope of slight swinging can be adjusted, etc. The alarm is applied to families, schools, enterprises and institutions, and can form an impending earthquake automatic alarm system in a county town or an area through combing a plurality of alarms.

Description

1. Technical field [0001] The invention relates to a multi-stage amplified shaking type all-round impending earthquake alarm, which takes the slight shaking of the ground surface as the alarm reference. It belongs to the technology of impending earthquake alarm equipment. 2. Background technology [0002] Up to now, although there are many types of instruments used for impending earthquake prediction and monitoring, people lack knowledge and skills on the causes of earthquakes and the selection of monitoring locations, etc., making it difficult to predict in advance when a major earthquake comes, causing a large number of casualties , the Wenchuan Earthquake is a tragic example. Therefore, it is urgent to solve this big problem. 3. Contents of the invention [0003] In order to solve the problem that people begin to evacuate before directly feeling the earthquake, the object of the present invention is to design an impending earthquake alarm, which can not only send out ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that people begin to evacuate before directly feeling the earthquake, the object of the present invention is to design an impending earthquake alarm, which can not only send out an alarm when the ground shakes slightly to wake people up to escape, but also means that the door frame is not closed when the ground shakes slightly. Easy to open the safety door due to deformation
