Description

The energy-saving electric burglar alarm

What the utility model energy-saving electric burglar alarm related to is a kind of device of burglar alarm.

Burglar alarm at present commonly used has all styles of, but structure is all comparatively complicated, and cost is higher, and is particularly not energy-conservation, reports to the police when on duty, needs electricity consumption, and the waste electric energy is bigger, will take No. 1 battery of several joints the every month that has, and also is a spending for the rural area.Deviser of the present utility model, the specialist's demand that breed fish from the rural area, raise chickens, supports duck, raises fruit trees designs, can antitheft, anti-theft, and on duty, the burglar alarm of reporting to the police, save electric energy.

The purpose of this utility model is for overcoming deficiency of the prior art, providing a kind of energy-saving electric burglar alarm, this alarm, in antitheft, not electricity consumption when anti-theft is on duty, energy-conservation, and stealer is when implementing to steal, as long as touch lead, just can report to the police, and power consumption is few.

The technical scheme of the utility model energy-saving electric burglar alarm is summarized as follows:

The utility model energy-saving electric burglar alarm is by information generator 15, signal lamp 12, alarm sound 13, exterior line power supply 14 constitutes, be characterized in that the positive and negative lead of information generator 15 usefulness links to each other with alarm sound 13 respectively, links to each other with signal lamp 12, links to each other with external power 14.

Described information generator 15 is by assembly 1, two grades of biswitches 2, electric battery 3, electromagnetic switch 4, information input socket 5, overlap joint tree lace 6, bucker 7, information accessory power outlet 10,11, overlap joint the end of a thread 17 formations such as grade, described assembly 1 is by triode 8, triode 9, resistance R 18 constitutes, collector on the triode 8 links to each other with base stage on the triode 9, base stage on the triode 8 and resistance R 18, emitter on the triode 9 links to each other, assembly 1 and two grades of biswitches 2, the positive pole of electric battery 3 is connected, the base stage of overlap joint tree lace 6 and triode 8, emitter, the negative pole of electric battery 3 links to each other, the collector of triode 9 and electromagnetic switch 4, the electric battery negative pole links to each other, external power 14 and two grades of biswitches 2, electromagnetic switch 4, alarm sound 13, signal lamp 12 links to each other.

The utility model has the advantages that: 1, simple in structure, cost is low, and every is no more than 30 yuan, is fit to family and buys, uses.2, economize on electricity power saving, because under anti-theft state, resistance R is bigger, circuit is in conduction state hardly, battery is not worked.3, highly sensitive, easy to use, report to the police accurately.

Below in conjunction with accompanying drawing detailed elaboration is done in circuit connection of the present utility model and formation, principle of work, using method.

Fig. 1 is an energy-saving electric burglar alarm modular construction connection diagram;

Fig. 2 is an energy-saving electric burglar alarm circuit diagram.

1 is assembly; 2 is two grades of biswitches; 3 is battery pack; 4 is electromagnetic switch; 5 are The input information socket, 6 are the overlap joint tree lace; 7 for landing bucker; 8 is triode; 9 is three Utmost point pipe; 10 and 11 is the information output socket; 12 is signal lamp; 13 is alarm sound; 14 are External power; 15 is information generator: 16 are antitheft zone; 17 are overlap joint the end of a thread; 18 is electricity Resistance R; 19 and 20 is the left and right binding post on the input information socket 5; 21 and 22 for information defeated Go out left and right sides binding post on the socket 10,23 and 24 is the left and right wiring on the information output socket 11 Post; Upper and lower binding post on 25 and 26 alarm sounds 13. Energy-saving electric is antitheft when using During alarm duty alarm in antitheft or evening, will overlap tree lace 6 and be arranged in antitheft regional 16, Overlap joint tree lace 6 will be surrounded by antitheft article, by Fig. 1 each assembly is connected, and takes A termination that connects tree lace 6 is inserted on the left binding post 19 of input information socket 5, and the other end patches On right binding post 20; The left side that the lead one of signal lamp 12 terminates at information output socket 10 connects On the terminal 21, the other end is connected on the right binding post 22; Binding post 25 on the alarm sound 13 with Left terminal 23 on the information output socket 11 connects, and lower binding post 26 is connected with right binding post 24; Information generator 15 is connected with the positive and negative electrode of external power 14, when stealer enters surveillance zone The time, overlap joint tree lace 6 must be stepped on, played or lift, severs, at this moment, pilferage information enters In the information generator 15, this information is amplified one tunnel information through the conversion of information generator 15 Be input to alarm sound 13, give the alarm immediately, utter a sound people stealer is caught.

Its operation principle and circuit thereof are described in detail as follows:

One, anti-theft state:

Among Fig. 2, the Ka-b on two grades of biswitches 2 pushes the position of a, and battery pack 3 has been connected, External power 14 has been connected, all can be at any time to each circuit supply, and the energy-saving electric alarm is in anti-Steal alarm condition, because the conducting effect of the overlap joint the end of a thread 17 on the overlap joint tree lace 6, so that three Base stage short circuit on the utmost point pipe, two triodes are in cut-off state, and electromagnetic switch 4 is not closed, Signal lamp 12 and alarm sound are not worked.

Two, alarm condition, namely implement to report to the police:

When stealer enters antitheft zone, implement to steal, will overlap that tree lace 6 is stepped on, the road or The person lifts, severs, and overlap joint the end of a thread 17 any joint land, the current lead-through of triode 8, Circuit is: the positive pole of battery pack 3 → two grade biswitch 2 → battery pack R18 → triode 8 → electricity The negative pole of pond group 3. Then triode 9 conductings, electric current increases to 100～150mA, electric current stream The distance of crossing is: the positive pole of battery pack 3 → two grade biswitch 2 → triode 9 → electromagnetic switch 4 The negative pole of → battery pack 3 is just because of the electric current that flows through the coil on the electromagnetic switch 4 is greater than 100～150mA, the K point on the electromagnetic switch 4 is closed, and this moment, the voltage of external power 14 was added to signal On the lamp 12, signal lamp 12 is shinny, the beginning of reporting to the police, and its circuit is: the positive pole of external power 14 → Left binding post on K point on two grades of biswitch 2 → electromagnetic switch 4 → information output socket 10 The negative pole of 21 → signal lamp 12 → right binding post 22 → external power 14. Meanwhile, alarm sound The circuit of sound 13 is connected, and sends alarm sound, and its circuit is: the positive pole of external power 14 → two The left binding post 23 that K point on shelves biswitch 2 → electromagnetic switch 4 → information output socket is 11 → alarm sound 13 → binding post 24 → external power 14 negative poles, alarm sound 13 and signal lamp 12 Work simultaneously, reach fabulous warning effect.

Embodiment: the utility model is made two according to above-mentioned Fig. 1, Fig. 2, and effect all can.
