Abstract
The utility model discloses an electric power apparatus theft-proof alarm device, comprising a stabilized voltage, current limiting, charging and protecting controlling circuit of a storage cell. The output terminal of the stabilized voltage, current limiting, charging and protecting controlling circuit is connected with a lighting lamp through a switch circuit a trigger, and connected with a power-off alarm circuit through a switch circuit II of a trigger. The switch circuit I of a trigger and the switch circuit II of a trigger are both connected with a switch AN1. The alarm device can immediately alarm when electric power facilities are stolen, destroyed and power-off to lead administrators to patrol in time to protect the electric power facilities. The utility model can accomplish alarm through one switch. The utility model has the advantages of lighting control and convenient operation.
Description
The utility model belongs to the electric power facilities anti-theft warning device, is specifically related to the burglar alarm that cuts off the power supply.
After rural power, city electricity electric network reconstruction were finished at present, transformer and power circuit often became the offender and steal object, and some regional electric power facility is stolen quite serious in the rural area.After these facilities are destroyed, cause large-scale power failure, bring inconvenience for commercial production and people's lives, bring loss to power department simultaneously.When the electric power facility theft took place now, the electric power facility managerial personnel often can not promptly know, can not check in time that circuit arrests the criminal of stealing, protected electric power facility.
The purpose of this utility model is to provide a kind of electric power facilities anti-theft, power-off alarm, and the device of floor light is to solve above-mentioned problem.
For realizing the purpose of this utility model; the inventor proposes following technical scheme; it comprises the voltage stabilizing current-limiting charge of accumulator and protection control circuit; its output terminal is connected with illuminating lamp by trigger switch circuit I; be connected with cut-offing alarming circuit by trigger switch circuit II simultaneously, trigger switch circuit I all is connected with button AN1 with trigger switch circuit II.
This alarm has warning function, when the stolen destruction of electric power facility, and the line of electric force outage; alarm is reported to the police at once, opens illuminating lamp simultaneously, makes late into the night keeper on duty can find the ANOMALOUS VARIATIONS of electric power facility rapidly in the very first time; the circuit of patrolling is immediately arrested the criminal of stealing, the protection electric power facility.Easy to use, also can be used for daily floor light, the sound and light alarm place.It only needs to finish illumination, controlling alarm with a switch.
Accompanying drawing alarm circuit figure.
Embodiment: as shown in the figure
The voltage stabilizing current-limiting charge of accumulator and protection control circuit are that transformer T is connected with bridge rectifier circuit BD1, and bridge rectifier circuit BD1 output is connected with capacitor C 1.Filtering output is connected with resistance R 1 luminotron LED1; Be connected with triode T1 by resistance R 3, the emitter of triode T1 is connected with accumulator B by insurance FUSE1; Be connected with trigger switch circuit I, trigger switch circuit II by resistance R 4, R5.
Trigger switch circuit I comprises trigger 4013 (U1B), its pin one 0 is that the R end is connected with circuit R4, R5, pin one 1 is that the CLK end is connected with button AN1, pin 9,12 connects, be that the D end connects and composes self-locking with the Q end, pin one 3 is that the Q end is connected with triode T2 by resistance R 7, and triode T2 is connected with illuminating lamp.
Trigger switch circuit II comprises trigger 4013 (U1A), its pin 6 is that the S end is connected with resistance R 4, R5, pin 5 is the D end, pipe 3 is a CLK end ground connection, pin 4 is that the R end is connected with button AN1, and pin two is that the Q end is connected with triode T3 by diode D2, and resistance R 4, R5 are connected with triode T3 by diode D3 resistance R 8, triode T3 is connected with triode T4, and triode T4 is connected with cut-offing alarming circuit P.
Its principle of work is as follows:
Voltage stabilizing current-limiting charge function, anti-overcharge: the 220V civil power carries out bridge rectifier by BD1 again after transformer T step-down.Thereby obtain level and smooth DC voltage at capacitor C 1 two ends through capacitor C 1 filtering.Wherein resistance R 1 and luminotron LED1 constitute charging and civil power indication.In order to prevent overcharge to accumulator, damage accumulator, adopt by resistance R 3, triode T1, resistance R 2, the current limliting mu balanced circuit that stabilivolt ZD1 constitutes will guarantee that it is in stable floating charge state in case accumulator is full of by above element built-up circuit.
Safety precaution: thus insurance FUSE1 is in order to prevent that short circuit from damaging battery.Trigger 4013U1B triode T2 and button AN1 constitute the on-off circuit of lamp.
Lighting theory: when the warning torch is inserted on the civil power, constitute resistor network, make the R end of trigger U1B be in high potential state, make circuit be in reset mode by resistance R 4, R5.In case dial plug down, then can pass through button AN1 open and close lamp.Whenever click, then circuit upset once, when its principle is the Q high level, Q low level then, the D end also is a low level so, examination clicks button AN1, then gives pulse of trigger U1B, then Q forwards high level to, Q is a low level, so also high level of D.When clicking button AN1 again, then circuit will turn; Thereby the on and off of control lamp.
Outage is reported to the police automatically: trigger U1A then has been the on-off action of warning circuit, and when external power supply was communicated with, the base stage of the S of trigger 4013U1A end and triode T3 was in noble potential, and triode T3 ends.In case power down, the S end of trigger U1A then is in electronegative potential.The base stage of triode T3 causes the conducting of triode T4 because of power down is in the electronegative potential conducting so, and chimes of doom is sent in warning circuit work.In case press the button AN1, the R end of trigger 4013U1A obtains a pulse, circuit reset, and then the Q end causes that for high level triode T3 ends, making reports to the police stops.Want to recover to report to the police, have only and plug civil power once more, make trigger 4013U1A be in SM set mode.
