Abstract

The utility model relates to an electric wire anti-theft alarm. An electric wire is connected with a normally closed relay (1); one elastic point of the normally closed relay (1) is connected with a power supply (3); one end of a sound organ (2) (a buzzer, a horn) is connected with the power supply, and the other end is connected with a contact A; the above components are all arranged in a hull. The utility model has the advantages of giving an alarm when a thief cuts the electric wire and informing the duty staff or residents of catching the thief, and simultaneously frightening the criminal to stop committing crimes, thereby reducing the loss.

Description

Electric wire anti-theft alarm

Technical field

The utility model relates to the alarm technical field, specifically a kind of electric wire anti-theft alarm.

Background technology

Some present lawless persons, at night or unmanned place a national grid or a residence name electricity consumption electric wire are stolen, cut away that a large amount of electric wires becomes copper or aluminium is sold for money, make resident, normally electricity consumption of office, make plant downtime, stop production and caused very big loss to country.

The utility model content

The purpose of this utility model is that design is a kind of when the lawless person cuts electric wire steathily, and alarm sends huge chimes of doom, in order to notify the relevant personnel, has deterrent effects to stop to steal the behavior electric wire anti-theft alarm to the lawless person simultaneously.

The utility model electric wire anti-theft alarm comprises: electric wire links to each other with a normally closed relay 1, and a DISCRETE ELASTIC SUPPORTS of normally closed relay 1 links to each other with power supply 3, acoustical generator 2 (hummers, loudspeaker) one links to each other with power supply, and the other end links to each other with a contact A, and above components and parts are all cased.

Warning is achieved in that

After the lawless person cuts off electric wire, the spring contact of normally closed relay is upspring, contact with contact A, then circuit is connected, the acoustical generator warning of sounding, operator on duty or near residence name are heard after, just be on the scene and arrest lawless people, or lawless people hears to report to the police and has a guilty conscience, and stops criminal activity, reduces the loss like this.

The advantage of the utility model electric wire anti-theft alarm is: can prevent that lawless people from when the robber cuts electric wire, sending chimes of doom, notify the staff or occupy name and grab the offender, deter criminal simultaneously and stop crime, reduce the loss.

Embodiment

According to Fig. 1, shown in Figure 2, electric wire links to each other with a normally closed condenser 1, and a DISCRETE ELASTIC SUPPORTS of normally closed condenser 1 links to each other with power supply 3, and one of acoustical generator 2 (hummer, loudspeaker) links to each other with power supply, and the other end links to each other with a contact A, and above components and parts are all cased.

Claims (1)

1. electric wire anti-theft alarm, it is characterized in that: electric wire links to each other with a normally closed condenser (1), and a DISCRETE ELASTIC SUPPORTS of normally closed condenser (1) links to each other with power supply (3), and (2) one of acoustical generators link to each other with power supply, the other end links to each other with a contact A, and above components and parts are all cased.
