Abstract
The utility model relates to an alarm, in particular to an earthquake alarm. The earthquake alarm comprises an alarm body, a photosensitive resistor, a manual switch, a lamp bulb, an inductive switch and a voltage stabilizing power source, wherein the alarm body, the photosensitive resistor, the lamp bulb, the inductive switch and the voltage stabilizing power source each comprise an endpoint a and an endpoint b, the manual switch comprises an endpoint a, an endpoint b and an endpoint c. The endpoint a of the photosensitive resistor is connected with the endpoint b of the alarm body, a wire is led out from a place between the endpoint a of the photosensitive resistor and the endpoint b of the alarm body to be connected with the endpoint a of the manual switch, the endpoint a of the alarm body is connected with the endpoint a of the inductive switch, the endpoint b of inductive switch is connected with the endpoint a of the power source after being connected with the endpoint b of the manual switch, the endpoint b of the photosensitive resistor is connected to the endpoint b of the power source after being connected with the endpoint b of the lamp bulb, and the endpoint a of the lamp bulb is connected with the endpoint c of the manual switch. The earthquake alarm is simple in structure, can be used as a common illuminating lamp when an earthquake does not happen and can automatically give out an alarm when an earthquake happens to warn people to escape, the earthquake alarm further can automatically provide illumination if an earthquake happens at night to help people escaping for their life find an escaping route fast and save valuable escaping time, and therefore casualties are reduced.
Description
(1) technical field
The utility model relates to a kind of alarm, particularly a kind of earthquake Alarm.
(2) background technology
Frequently there is earthquake disaster in China in recent years, and casualties situation is serious.Earthquake meeting causes great threat to people's life security, and especially at night, people are mostly in sleep, can not feel on the one hand the generation of earthquake, night, light was dark on the other hand, needed manual unlocking illuminating lamp just can find escape route, and this has just wasted very valuable escape time.
Still do not have in the world at present can look-ahead earthquake technology, lack the method for quick alarm earthquake, there are some earthquake siren for household, but because function singleness, high, impracticable being difficult to of cost promote.
(3) summary of the invention
The purpose of this utility model is to provide a kind of earthquake Alarm simple in structure, when earthquake does not occur, can be used as general lighting lamp and uses; When earthquake occurs, send in time warning, remind people's escape, if earthquake occurs in night, can also automatically provide illumination, help people to find escape route, reduce casualties.
The problem that the utility model solves is achieved through the following technical solutions:
Earthquake Alarm comprises alarm, photoresistance, hand switch, bulb, inductive switch and a power supply, and described alarm, photoresistance, bulb and inductive switch, power supply all comprise a, b two wiring end points.Described hand switch is single-pole double-throw switch (SPDT), comprises a, b, and tri-wiring end points of c, a end and b end are moved end not, it is moved end that c holds.
Photoresistance a end is connected with alarm b end, between photoresistance a end is held with alarm b, draw a wire and be connected hand switch a end, alarm a end is connected with inductive switch a end, after being connected with hand switch b end, inductive switch b end is connected with power supply a end, photoresistance b end is connected on power supply b end after being connected with bulb b end, and bulb a end is connected with hand switch c end.
The utility model is further realized by following technological means:
Described power supply is 220V domestic power supply.
Described bulb is home lighting bulb.
Described inductive switch can be closed after being subject to vibrations, switches on power.
Described hand switch is by manual control, and hand switch exists and disconnects, and connects a, connects b, three kinds of states.
(4) accompanying drawing explanation
Accompanying drawing is schematic diagram of the present utility model.
1 alarm in figure, 2 photoresistance, 3 bulbs, 4 inductive switches, 5 hand switches, 6 power supplys.
(5) embodiment
In order to make technological means of the present utility model, creation characteristic, to reach object and the clear understanding of effect, below in conjunction with the further elaboration of concrete diagram the utility model.
As shown in drawings, a kind of earthquake Alarm, described earthquake Alarm comprises 1 alarm, 2 photoresistance, 3 bulbs, 4 inductive switches, 5 hand switches, 6 power supplys.
By day or the length of one's sleep, do not need bulb illumination, 5 hand switches close at a end.Now, 3 illuminating lamp a ends are connected with 1 alarm b end after being connected with 2 photoresistance a ends; After being connected with 3 bulb b ends, the b end of 2 photoresistance is connected with 6 power supply b ends.When earthquake does not occur, 4 inductive switches disconnect, and circuit no current passes through, and 1 alarm does not ring, and 3 bulbs do not work.When earthquake occurs, 4 inductive switches are given a shock, and 4 inductive switch a ends are logical with b termination, and 4 inductive switches are closed, circuit turn-on, and 1 alarm gives the alarm.Cause now 3 bulbs is connected with 1 alarm with after 2 photoresistance parallel connections, if earthquake occurs by day, 2 photoresistance are subject to illumination, and resistance is minimum, and 3 bulbs are by short circuit, not shinny; If earthquake occurs at night, 2 photoresistance resistance are larger, and 3 bulbs can be by short circuit, and shinny, help illumination, contributes to people's fast-escape, reduces casualties.
Before falling asleep at night, need illumination, 5 hand switches are got to b end.When earthquake does not occur, 4 inductive switches disconnect, and only have 3 bulbs to connect 6 power supplys in circuit, and 3 bulbs are shinny, and normal lighting is provided.When earthquake occurs, 4 inductive switch a ends are got to b end, 2 photoresistance are in parallel with 3 bulbs after connecting with 1 alarm, whole circuit turn-on, and 1 alarm gives the alarm, remind people's escape, 3 bulbs are shinny, and illumination is provided, and help people to seek early escape route, thereby help people's fast-escape, reduce injures and deaths.
The beneficial effects of the utility model are:
A kind of earthquake Alarm simple in structure is provided, when earthquake does not occur, can make general lighting lamp uses, when earthquake, can automatically send warning, remind people's escape, if earthquake occurs in night, illumination can also be provided automatically, help survivor to find fast escape route, help to save valuable escape time, reduce injures and deaths.
Claims (1)
