Abstract

The invention discloses an earthquake pre-alarm. The pre-alarm comprises a mask housing, and a sensitivity adjusting knob is fixedly embedded into the mask housing; a hanging spring is fixedly mountedon the sensitivity adjusting knob; a vertical magnetic pendulum bob is fixedly mounted on the hanging spring; an upper-layer circuit board is arranged in the mask housing, a damping metal layer is arranged in the center of the upper-layer circuit board, an induction coil shielding box is fixedly installed at the position, corresponding to the damping metal layer, of the upper-layer circuit board,a vertical pendulum magnetic induction coil is arranged in the induction coil shielding box, and an indicator lamp is further fixedly installed on the upper-layer circuit board. According to the alarm, the principle that micro-inclination and micro-motion often occur several hours to several days before an earthquake is adopted, the vertical pendulum principle is applied for detection, signal detection is achieved in an electromagnetic induction mode, then detected weak signals are amplified through a circuit amplifier, and early warning can be given out several hours before the earthquake through a related conditioning circuit.

Description

technical field [0001] The invention relates to the technical field of earthquake detection, in particular to an earthquake pre-alarm. Background technique [0002] Earthquakes, also known as ground motions and ground vibrations, are vibrations caused by the rapid release of energy from the earth's crust. During this period, seismic waves will be generated. Earth's plates are squeezed and collided with each other, causing dislocations on the edges of the plates and inside the plates. Movement and rupture are the main causes of earthquakes. [0003] At present, most of the independent earthquake alarm methods are to utilize the principle of the speed difference between P wave and S wave, apply the mechanical vibration of earthquake wave, and trigger the sound device to send an alarm through a certain sensor switch. [0004] But these alarms are actually just a few seconds switch alarm after the earthquake took place, it is impossible to send earthquake early warning effect f...
