Abstract
The utility model relates to a simple earthquake alarm in the field of earthquake-proof alarm device. The technical scheme is as follows: a circuit board, batteries, a light emitting diodes, a switch and a speaker are arranged in a box body, and a supporting point is led out of the box body; a counter weight is connected with the lower part of the supporting point by a metal wire, and a metal ring is fixed at the outer part of the metal wire; the circuit which constitutes the circuit board is based on a time base circuit, and the input terminal is connected with a resistor R1, a resistor R2, a capacitor C1 and a capacitor C2, and then is respectively connected with the metal wire and the metal ring; and the output terminal is connected with a diode D, a resistor R3, the light-emitting diodes LED, the speaker L, a power supply DC and the switch K. The utility model has simple structure and low cost; once the shake and tilt are caused by an earthquake, the utility model can give a sound and light alarm to quickly and effectively remind people.
Description
Technical field:
The utility model relates to a kind of simple earthquake alarm instrument in shockproof warning device field.
Background technology:
China belongs to earthquake frequent activities district, in case when earthquake takes place, as the untimely buildings of fleeing from, bring danger will for people's life.Existing seismograph all belongs to the professional equipment that earthquake prediction mechanism of country possesses, and this kind equipment costs an arm and a leg, and is difficult to popularization and application.And the earthquake alarm that can use in the family is still rare.
The utility model content:
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple earthquake alarm instrument that sends earthquake alarm immediately that is easy to popularize, have is provided.
Technical scheme is: circuit board together with battery, light emitting diode, switch and loudspeaker device in a box body, on box body, draw a fulcrum, the fulcrum below connects weight by tinsel, in tinsel external stability quoit is arranged, the circuit of built-up circuit plate is to be core with time base circuit IC, its input end inserts respectively on tinsel and the quoit after connecting resistance R 1, resistance R 2, capacitor C 1, capacitor C 2, and its output terminal connects diode D, resistance R 3, LED and loudspeaker L to power supply DC, K switch.
Of the present utility model have simple in structurely, with low cost, in case caused under vibrations or the inclination situation by earthquake, can send sound and light alarm, gives people with alarm efficiently and effectively.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the circuit theory diagrams of circuit board.
Embodiment:
With reference to accompanying drawing 1, circuit board 5 in a box body 8, is drawn a fulcrum 7 together with battery 1, light emitting diode 9, switch and loudspeaker 2 devices on box body, and fulcrum 7 belows connect weight 3 by tinsel 6, in tinsel 6 external stabilities quoit 4 are arranged.
With reference to accompanying drawing 2,2 pin of time base circuit IC connect resistance R 2 and sensing circuit; 6,7 pin of time base circuit IC connect resistance R 1 is connected time base circuit IC with capacitor C 1, capacitor C 25 pin; Form pulse enable formula monostable circuit.Time base circuit IC signal input part is connected with the sensing circuit of being made up of tinsel 6 (GS), weight 3 (ZC) and quoit 4 (TQ); The GD of sensing circuit is the insulation point of fixity, and the lower end of tinsel GS connects weight ZC, and tinsel GS passes quoit TQ.Time base circuit IC output terminal 3 pin connect alarming horn L to power supply DC (battery 1), K switch through diode D, also connect resistance R 3, LED at output terminal through diode 1D in addition.
Home-use seismograph of the present utility model in use, at ordinary times, because the effect of insulation point of fixity GD and weight ZC, tinsel GS does not contact with quoit TQ, circuit remains static, LED and alarming horn L all do not work.Under the earth generation vibrations or inclination situation, tinsel GS is subjected to the effect of weight ZC with quoit TQ and contacts, and circuit is triggered, and LED and alarming horn L all work and can send sound and light alarm, and the prompting people note.
Claims (1)
1, a kind of simple earthquake alarm instrument, it is characterized in that: circuit board together with battery, light emitting diode, switch and loudspeaker device in a box body, on box body, draw a fulcrum, the fulcrum below connects weight by tinsel, in tinsel external stability quoit is arranged, the circuit of built-up circuit plate is to be core with time base circuit IC, its input end inserts respectively on tinsel and the quoit after connecting resistance R 1, resistance R 2, capacitor C 1, capacitor C 2, and its output terminal connects diode D, resistance R 3, LED and loudspeaker L to power supply DC, K switch.
