Violent earthquake predictor of liquid suspended and magnetic suspended insulation heavy seismometer

Abstract

The invention provides a violent earthquake predictor of a liquid suspended and magnetic suspended insulation heavy seismometer. The seismometer connected with a magnet is suspended on a horizontal table magnet, an insulation tube is vertically connected on a horizontal table top, a plurality of laser interferometers with light needles aligned to the outer diameter of the seismometer are connected on the inner wall of the insulation tube, the lower side of an insulation tube cover plate is connected with a electromagnetic transducer used for restricting the seismometer in a non-contact way, the horizontal table is placed on the liquid level of liquid arranged in a small submerged floating ball, a lower compartment of the small submerged floating ball is loaded with fine iron sand and vertically floats in the liquid in a compartment of a large submerged floating ball in a submerged way, a lower compartment of the large submerged floating ball is loaded with coarse iron sand and vertically floats in the liquid in a liquid tank in a submerged way, and a cable and a data wire are connected with a signal amplifier and a computer after the sealing processing. The invention can filter non-earthquake signals through the liquid, can record the rate of displacement of the integral sudden quake of the earth through a non-contact measuring instrument, can obtain parameters of time and regions to generate the violent earthquake through the analysis by earthquake model processing software, and can be used as an instrument for predicting the earthquake through capturing earthquake precursor signals.

Description

technical field [0001] The invention relates to a large earthquake forecasting instrument which uses a liquid floating platform to block the direct contact between a magnetic levitation heavy object shock picker and the earth's surface. Specifically, after the liquid material is added between the vibration pickup of the existing seismograph and the earth's surface to filter the small-scale shock waves on the earth's surface, the magnetic levitation weight is measured with a laser interferometer (or micrometer) and an electromagnetic sensor. The displacement rate of the vibration pickup with the sudden displacement of the earth as a whole, and through the calculation and analysis of the signal amplifier and the digital information processing software of the earthquake model, finally obtain the large earthquake forecaster for the region and time when strong earthquakes will occur. The instrument is suitable for the field of instrumentation equipment manufacturing. Background t...
