Abstract
The invention discloses a safety fence for a power maintenance site, which is formed by splicing a plurality of unit protective guards. A pressure-touch switch is arranged between two unit protective guards which are mutually contacted, or the two unit protective guards are respectively provided with a magnetic button. A fence disconnection alarming circuit mainly consists of a voltage-stabilizing circuit (adopting a voltage-stabilizing diode for stabilizing voltage), a triode switch circuit, a power amplifying circuit and an alarming circuit. When the magnetic button or the pressure-touch switch at any protective guard in the fence is switched off, the triode switch circuit is disconnected, and the alarm gives an alarming sound. The safety fence disclosed by the invention has the advantage that the illegal behavior for crossing over safety guards can be effectively prevented, and has the characteristics that the structure is simple and practical and the construction safety can be ensured.

Resistance R 7 one termination battery BT1 are anodal; It is anodal that resistance R 7 another termination compound transistor Q1 base stages, compound transistor Q1 colelctor electrode meet voltage-stabiliser tube D1, compound transistor Q1 grounded emitter; An above-mentioned magnetic snapping compound transistor Q1 base stage; Another magnetic snapping ground, perhaps above-mentioned pressure touch switch one termination compound transistor Q1 base stage, other end ground connection; 1 pin of power amplification chip U1 connects voltage-stabiliser tube D1 positive pole after series resistor R1, the resistance R 3 in order; Resistance R 2 one termination battery BT1 are anodal, and the other end is connected to the node of resistance R 1 and resistance R 3, and electrochemical capacitor C3 positive pole is connected to the node of resistance R 1 and resistance R 3; Electrochemical capacitor C3 negative pole connects 3 pin and the voltage-stabiliser tube D1 positive pole of power amplification chip U1 simultaneously; It is anodal to be connected to electrochemical capacitor C5 behind the 2 pin series resistor R4 of power amplification chip U1, and electrochemical capacitor C5 negative pole is connected to loudspeaker TS1 one end, and the loudspeaker TS1 other end is connected to 3 pin of power amplification chip U1; It is anodal that 4 pin of power amplification chip U1 meet electrochemical capacitor C5; Resistance R 5 one is terminated at 2 pin of power amplification chip U1, and the other end is connected to the node of resistance R 1 and resistance R 3, and it is anodal that 5 pin of power amplification chip U1 meet battery BT1.
Also have voice warning circuit: 1 pin of speech chip U2 is connected to voltage-stabiliser tube D1 negative pole, and 2 pin of speech chip U2 are connected to 3 pin of power amplification chip U1, is connected to 1 pin of power amplification chip U1 after the 3 pin serial connection capacitor C 4 of speech chip U2.
The model of above-mentioned power amplification chip U1 is TDA3020A, and the model of speech chip U2 is MIC, and the model of compound transistor Q1 is TIP122, and voltage-stabiliser tube D1 is the 3.3V voltage-stabiliser tube.
The present invention has following characteristics:
1, after any protective guard magnetic button or pressure in the fence were touched the switch disconnection, transistor switching circuit broke off, and alarm sends " warns, warns the No striding safe fence! " sound.
2, after the magnetic button that breaks off or pressure are touched switch and are connected once more, circuit closed, alarm audible closure.
3, alarm adopts the 12V storage battery power supply, and whole loop has only very little current drain in the standby process, so stand-by time can reach half a year.
If 4 alarms are in the state of warning sounding for a long time, the normal working time theoretical value of battery: 70 hours.
5, the alarm battery adopts the charging of 12V Switching Power Supply.
This fence can be prevented the act of violating regulations of crossing over safe fence, and is lower to the external peopleware in job site especially, the situation that awareness of safety is relatively poor, act on more obvious, guaranteed that site safety produces controlled, controlling and can controlling, improved the safety work level.
