Description

Early stage alarm bell for earthquake

The utility model relates to a kind of clock alarm technique field, the clock technology field that utilizes the magnetic storm phenomenon to report to the police before particularly a kind of earthquake.

Each country of the world is provided with fragmentary seismic monitoring standard station, point in each department, the earth's crust, the earth mantle of one's respective area carried out the monitoring that the geology physical data changes, and reaches a conclusion after calculating.At present to the monitoring of earthquake mainly by observation to the irregular change of the horizontal magnetic declination of earth magnetism and vertical dip angle, and continual observation is carried out in the variation of the physical datas such as temperature, water level, hydraulic pressure of electricity, terrestrial stress, underground water source over the ground.In addition the brainstrust of the Geophysics Institute of various countries constantly calculate extraterrestrial gravitation to geophysical influence, calculate of the influence of the sudden and violent time that becomes of sunspot to the magnetic field of the earth, use various forms of instruments to carry out comprehensive measurement, make analysis and judgement according to the geological condition of each department.National meteorological department removes the normal evolution to atmosphere, and the moving direction speed on the inclination of the test species of clouds, wind direction, wind speed, air pressure face, humiture, changes in temperature sharp side is made outside the reckoning forecast and also will be assisted earthquake department to observe the appearance of special species of clouds seismic cloud.Above-mentioned all surveying instruments and measurement means concentrate on only a few earthquake prediction platform, also do not have which country or area on broadcasting, TV and newspaper, to resemble at present and issue earthquake prediction issue weather forecast, risk of forest fire, the air pollution forecasting the shake forward direction common people, be unfavorable for mass presdiction and disaster prevention like this, when there are earthquake situations the adjoining area, will bring the critical sense of safety to people.

The purpose of this utility model is to provide a kind of preceding warning device of earthquake that utilizes to enter family with the form of household electrical appliances, with the problem of real solution mass presdiction and disaster prevention.

The purpose of this utility model is to realize like this.It includes a crystal clock, and a flip flop equipment that utilizes geomagnetic declination or earth's magnetic dip angle generation magnetic storm to change is installed at the top of crystal clock, also has a time control circuit of the magnetic storm signal being reported to the police and showing by crystal clock in crystal clock.Above-mentioned flip flop equipment is to have sieve board that two parallel magnetic are held in both hands by being suspended with one on the addendum cone that is fixed on the flip flop equipment housing, at sieve board upper support one contact pin is arranged, the contact pin two ends are limited in respectively in the spill magnetic declination contact chip and ungulate inclination angle banking stop that is fixed on the flip flop equipment housing.

The utility model is because the form that earthquake early warning device and crystal clock are integrated in one with civilian goods enters family, and therefore have the following advantages: a few hours send earthquake to the place in earthquake region user and give institute's spot seismic wave in alert signal or the automatic alarm certain distance before big shake; When reporting to the police, note first the time that the fine motion earthquake takes place to take place in magnetic storm or the certain distance exactly automatically., group newspaper network anti-with real formation group only in this way could be for the only a few measuring platforms, stand and scientific research department provides in time, information in many ways reliably.

Mechanism: horizontal magnetic deviation is meant the needle that is hanging, and indicated direction is not the true meridian direction, i.e. angle between magnetic meridian and the true meridian; And absolute force is called vertical magnetic dip with the angle of surface level.In that taking place, fission that the earthquake foreshock district's earth mantle or earth's crust surface geology inspires generation because of certain reason can make that magnetic-bearing mineral matter changes in the geology; as the mutual high-energy friction of the disconnected strong plate in the earth deep layer, bump and the geoelectric effect that produces is an all multifactor major reason that causes changes of magnetic field.What shake magnetic prestorm is to experience a very long evolution process, that is to say it is that the variation of geology generation matter will reach a critical mileage, when reaching, the variation of this germplasm can produce when making big floorboard that fission take place, just can at first cause owing to geology changes to produce " machinery " motion, change into heat energy or luminous energy.Be that light and heat all can produce electric energy by mechanical effect, electric energy can be converted into magnetic energy again, emergent like this externally-applied magnetic field is for the huge magnetic field of this piece of the earth, and influence is inappreciable certainly, but has really played the variation of amount for certain regional normal magnetic field of the earth.We can say that any reason inspires the generation that causes earthquake in the geology finally all can be embodied by magnetic strength, the basic reason that this earthquake just generates.So take place at every turn that changes of magnetic field all tangible magnetic variation will take place in the earthquake region before critical point before the earthquake, Here it is, and the main cause of magnetic storm takes place before shake.Magnetic storm generation before the shake can make the magnetic declination earthquake region in produce bigger skew, simultaneously owing to the magnetic field in earth somewhere is directly influenced the change of magnetic dip because of adding magnetic force.
