Description
The utility model belongs to electronic technology field, particularly a kind of magnetic control primary seismic wave audible-visual annunciator of impending earthquake warning usefulness.
In recent years, earthquake frequently takes place in the world, and China is between the world's two violent earthquake bands, belongs to one of the countries of shaking more.China is vast in territory, and seismic profile is extensive, works the mischief greatly.At present, in the method that impending earthquake is reported to the police, having of using always in the family is following several: (1) adopts the method for handstand bottle, and bottle falls down to the ground, and realizes reporting to the police.(2) connect becket and metal sash weight with electric bell respectively by electric wire, connect AC power, electric bell is reported to the police.Above method is the warnings of three kinds of seismic events when all arriving, and the effect of observing and predicting or the alerting signal that all can not reach primary seismic wave well are imperfect, can not carry out light night and report to the police.
At above situation, we with reference to, retrieved " earthquake knowledge question ", " natural science include file " and Zhangjiakou seismological bureau Zhang Zhigang and published argumentation about earthquake such as " Zhangjiakou earthquake general introduction " on " Zhangjiakou science and technology ", understood the ABC of earthquake.Utilize the electronic technology knowledge of learning by oneself, about the introduction of music integrated circuit, lay a good foundation in reference " radio ", " CYBERSPACE " for reaching the realization the purpose of this utility model.
The purpose of this utility model provides a kind of magnetic control primary seismic wave audible-visual annunciator, and it can reach observes and predicts that primary seismic wave is concurrently spoken, the light warning, reaches the purpose of protection against and mitigation of earthquake disasters.
Principle of the present utility model is: according to three kinds of seismic wave propagation speed differences, same residence is identical with hypocentral distance, three kinds of seismic events have time of arrival have earlier after, so just produced the mistiming.It can cause that ground pitches the primary seismic wave velocity of propagation per second 5-6 kilometer that elder generation arrives, and is destructive less, and magnetic control primary seismic wave audible-visual annunciator sends sound, light warning after measuring primary seismic wave immediately.When treating destructive shear wave (speed per second 3-4 kilometer) greatly, ground roll (3 kilometers of speed per seconds) arrival, differed tens seconds to tens seconds time, (secondary wave, ground roll can cause that ground rolls, and vibrations are strong, and destruction is very big) the people urgent danger prevention of just racing against time.
The purpose of this utility model can realize like this: a kind of magnetic control primary seismic wave audible-visual annunciator, it is characterized in that the extension spring lower end hangs bar magnet, the lower end fixed installation magnetic switch of bar magnet, magnetic switch is connected between integrated circuit negative pole and the battery cathode; The integrated circuit trigger end is connected with the integrated circuit negative pole in the integrated circuit; Resistance R is connected on the integrated circuit; Five light output contacts of integrated circuit connect the diode (LED) negative pole respectively; The diode (LED) positive pole all is connected with the integrated circuit negative pole; Ic output connects the first transistor base stage, and the first transistor collector connects the transistor seconds base stage, and the transistor seconds collector connects loudspeaker, and the first transistor emitter connects the integrated circuit negative pole, and the transistor seconds emitter connects the integrated circuit positive pole.Above-mentioned extension spring, bar magnet, with magnetic switch in regular turn on straight line perpendicular to ground.
Owing to take technique scheme, realize that the household seismic compressional wave observes and predicts, send sound, light warning.It has the following advantages and good effect than aforementioned two types of household seismic methods of observing and predicting in road as far as we know:
When 1, primary seismic wave arrives, send sound, light warning immediately, strive for tens seconds to tens seconds time, make people's urgent danger prevention.
2, simple, the realization easily of circuit, ordinary electronic tradesman, radio amateur promptly can install by drawing, and unit, device just can be bought in electronics stores.
Sound, light gave a warning simultaneously when 3, primary seismic wave arrived, and were fit to anyone and any time, and night, effect was more obvious, made people recognize that immediately earthquake has taken place.
4, use dry cell power supply, not affected by environment, consumed power not is economical and practical at ordinary times.
Further illustrate the utility model below in conjunction with accompanying drawing embodiment.
