Electromagnetic wave excitation type earthquake early warning device

Abstract

The invention discloses an electromagnetic wave excitation type earthquake early warning device, which comprises a box body buried underground. A placing rack, a fixed box and a power supply are fixedly arranged in the box body; a plurality of solenoids are fixedly mounted in the fixed box; each solenoid is electrically connected with the power supply; two sliding seats are symmetrically welded onthe inner side wall of the box body; each sliding seat is provided with a connecting seat in a sliding mode; each connecting seat is in a U shape; induction pieces are installed on the two opposite side walls of each connecting seat respectively; a floating rod is placed between the two connecting seats; four triggering blocks are symmetrically arranged on the side wall of the floating rod; and the position of each triggering block corresponds to the position of the corresponding induction piece. The earthquake information is acquired by monitoring the change of the underground electromagnetic waves, and the propagation speed of the electromagnetic waves is greater than that of the earthquake waves, so that monitoring personnel can acquire related data more quickly and give an early warning to people in time, and casualties and property loss of the personnel are reduced.

Description

technical field [0001] The invention relates to the technical field of earthquake early warning, in particular to an electromagnetic wave excitation type earthquake early warning device. Background technique [0002] The mutual extrusion and collision between plates on the earth is the main cause of earthquakes. The intensity of earthquakes will also increase with the severity of plate damage and dislocation. The occurrence of earthquakes will not only cause houses to collapse, roads to collapse, and even cause For the occurrence of other geological disasters, the existing seismic detection devices mostly use the deep well monitoring method to calculate the key data such as magnitude, intensity, source and epicenter by detecting the non-destructive seismic waves emitted at the beginning of the earthquake, and then simulate the affected areas and issued early warnings. [0003] For high-intensity earthquakes, under the action of stress, the underground rock will be compresse...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the time and range of early warning of earthquakes by detecting changes in seismic waves in the prior art, while ignoring the changes in the underground electromagnetic field before the earthquake, resulting in the disadvantage of taking a long time to receive seismic signals , and proposed an electromagnetic wave excitation type earthquake early warning device
