Abstract
The utility model belongs to the electronic technical field, particularly an automatic earthquake alarm device which can indicate the concrete position of a person in distress trapped in a collapse building after an earthquake. The utility model is characterized in that the fluidity of mercury balls in a mercury switch and the switching action of a dual-pole four-throw toggle switch control the operating state of a circuit to automatically call for help via sound and light, replacing a person. A transistor is connected with an integrated circuit, a loudspeaker, a transfer switch, the mercury switch and a prefocus lamp. The utility model has the advantages of simple structure, clarified circuits, purchasable elements and high possibility to become products, and can help to rescue people in distress in time in areas with frequent earthquakes.
Description
This utility model belongs to electronic technology field, and is particularly a kind of after the earthquake, and indication is crushed on the earthquake auto saving alarm of person in distress's particular location in the buildings that collapses.
The annual average earthquake about 5,000,000 times that takes place in the whole world, about 50,000 times of 2.5-5 level felt earthquake, ruinous earthquake also have tens times.The loss that causes to the mankind when therefore earthquake takes place can't be estimated, and the casualties that especially causes is irreparable especially.
Casualties when earthquake takes place below mainly being pressed in by collapsed building, if most people can not get timely relief, will cause death.
Be crushed on the people of collapsing in the buildings, how could allow rescuer know particular location, it is limited depending own calling for help alone, consume one's strength.So just need a kind of replacement people in danger and call for help, allow rescuer know the rescue beacon of its particular location, the notice rescuer is in time rescued.According to above situation, we are developed into the earthquake auto saving alarm.By sound and optic signal indication people's particular location in danger, be convenient to rescuer and in time succour.
Consult a large amount of relevant technologies data and understand known to all previous violent earthquake situation according to us, release at present that infrared detecting set is sought, exploration seismic people in danger, also find initiatively to indicate earthquake the get into danger earthquake auto saving alarm of people's automatic calling for help of people's particular location, replacement that gets into danger with sound, light with lifesaving dog and heat.
The purpose of this utility model is: a kind of earthquake auto saving alarm is provided.It can send sound and optic signal indication distress personnel particular location automatically when earthquake, prevent that rescuer from disorderly looking for blindly, random digging, and reaches timely rescue, improves the purpose of rescuing efficient.
The purpose of this utility model can realize like this: when earthquake takes place, jolt continuously and rock in ground, make people's astasia make health fall down or be crushed on below the buildings, vertically be contained in mercury cut-off in the earthquake auto saving alarm on the person along with human body tilts, mercury bead is flowed connect earthquake auto saving alarm battery, make the earthquake auto saving alarm get electric work, produce the first aid sound of similar ambulance, bulb emits beam simultaneously.By sound, light, allow rescuer know to be rescued personnel's particular location.
The technical solution of the utility model is as follows: the earthquake auto saving alarm is thrown toggle switch K1, single-pole single-throw (SPST) toggle switch K2, loudspeaker Y, battery E and charging socket by mercury cut-off, integrated circuit KD9562, transistor 3DK4B, 3.8V optically focused miniature bulb, double-pole four and is formed.Double-pole four is thrown toggle switch K1 Control work state: 5 for the public translation contact, receive 1 retaining for shutdown, receive 2 retainings for acousto-optic and with, receive 3 retainings for luminous, to receive 4 retainings be sounding, can select gear in advance, also can be according to situation selection at that time.Integrated circuit KD9562 can produce 8 kinds of simulated sound, connects the 8th of trigger end and can produce ambulance sound.Transistor 3DK4B does audio frequency and amplifies, to increase volume.Single-pole single-throw (SPST) toggle switch K2 plays auxiliary mercury cut-off, makes the continuous working of rescue beacon energy.The mercury cut-off positioned vertical, contact makes progress, mercury bead is descending.Because the switching of mercury cut-off control battery, so rescue beacon consumed power not at ordinary times, volume has only the cigarette case size.
This utility model has the following advantages and good effect:
1. volume is little, easy to carry.
2. use powered battery, consumed power not is not affected by environment at ordinary times.
3. mercury bead is mobile strong, and mercury is quick on the draw than great; Hand switch K2 can make
Rescue beacon is called for help or interrupted the calling for help continuously; Toggle switch K1 can change duty,
Can sound, light and with and separately with sound or call for help with light separately.
4. of many uses, can be applied in the similar dangerous environment such as mine, down-hole.
Further illustrate the utility model below in conjunction with accompanying drawing embodiment:
Figure of description is the circuit theory diagrams of embodiment.Figure of abstract is the width of cloth figure in the Figure of description.
Among the figure: integrated circuit KD9562 (1), transistor 3DK4B (2), 8 ohm of loudspeaker Y (3), mercury cut-off (4), single-pole single-throw (SPST) toggle switch K2 (5), double-pole four are thrown toggle switch K1 (6), charging socket (7), 4.5V No.5 cell E (8), 3.8V spot light lamp bulb (9).Among the K1 1,2,3,4,5 is gear changeover contact sequence number, and 5 is the public translation contact, connects the 1-4 contact respectively by it.
Realize the best way of this utility model:
The base stage of transistor 3DK4B (2) connects the output terminal of integrated circuit KD9562 (1) in Figure of description; The collector of transistor (2) connects loudspeaker (3); Loudspeaker (3) other end connects respectively that integrated circuit (1) is anodal, an end of charging socket (7), battery (8) are anodal, an end of spot light lamp bulb (9); The emitter of transistor (2) connects the negative pole of integrated circuit (1), the 8th of the trigger end of integrated circuit (1), the 4th retaining of K1 (6) two-way, the 2nd retaining of K1 (6) the 1 tunnel respectively; Mercury cut-off (4) is connected the 5th retaining points of common connection of K1 (6) two-way with K2 (5) back in parallel one end, the other end connects the negative pole and the charging socket (7) of battery (8); The spot light lamp bulb other end connects the 2nd retaining contact of K1 (6) the 2 tunnel and the 3rd retaining contact of two-way.
Earthquake auto saving alarm circuit is simple, realizes easily, can change into product at an easy rate.And volume is little, and consumed power not is practical at ordinary times, when earthquake takes place with on, for the earthquake distress personnel in time obtains succouring the positive effect of performance.
