Abstract

An apparatus for preventing fire due to electric wiring is provided to block electric power supply before coating is damaged by sensing overheat of the wiring due to overload. A power supply unit(100) supplies power to a load(400). In case the current supplied from the power supply unit to the load is over reference current, a fuse box(300) blocks approval of current. A sensor(500) is connected between the fuse box and the load. The sensor outputs a control signal in case amount of the current applied to the load or the temperature of the wire connected between the fuse box and the load is over reference current or standard temperature. According to the control signal of the sensor, a blocking part(200) cut off the current flowing in the wire. According to the control signal of sensor, an alert part generates warning tone and alarm signal. The alarm signal is generated by a warning lamp consisting of an LED(Light Emitting Diode).

Description

Fire prevention device by electric wiring {FIRE PREVENTION APPARATUS BY ELECTRIC WIRING}

1 is a block diagram of a fire protection device by a conventional electric wiring.

Figure 2 is a block diagram of a fire protection device by electric wiring according to an embodiment of the present invention.

Figure 3 is a block diagram of a fire protection device by electric wiring according to an embodiment of the present invention.

The present invention relates to a fire protection device.

More specifically, the present invention relates to a fire prevention device by electric wiring connecting an automobile, a ship, etc. using an electric device.

In the case of the conventional fire protection device, as shown in FIG. 1, when the electric wiring of the vehicle is shorted, the breaker cuts off the power to prevent the spread of the fire. The fire was prevented by disconnection.

However, even if the magnitude of the current flowing through the fuse does not exceed the maximum rating of the fuse, there is a problem that a fire occurs due to an overload when the current flowing in the detailed wiring connected to each load through the fuse exceeds the maximum rated current of the wiring.

The present invention has been made in order to solve the above problems, it detects that the wiring is overheated by the overload to cut off the power supply before the coating is broken, the overcurrent state to the equipment driver in advance through sound or warning lights Its purpose is to provide a fire protection device due to electrical wiring to prevent fire by informing.

An object of the present invention described above, the power supply for supplying power to the load, the fuse box is cut off when the current supplied from the power supply to the load is greater than the reference current to block the application of the current, the fuse box and the A sensing unit and a sensing unit connected between loads to sense an amount of current applied to the load or to sense a temperature of a wire connected between the fuse box and the load to output a control signal when the reference current or the reference temperature is greater than It is achieved by providing a fire prevention device by electric wiring, characterized in that it comprises a cut-off portion for receiving the control signal to block the current flowing through the wire.

Fire prevention device by an electrical wiring according to a preferred feature of the present invention, the control unit receives the control signal from the detector further comprises an alarm unit for generating a warning signal through a warning light consisting of a warning sound and LED.

Hereinafter, with reference to the accompanying drawings will be described in more detail a fire protection device by electrical wiring according to an embodiment of the present invention.

Figure 2 is a block diagram of a fire protection device by electric wiring according to an embodiment of the present invention.

Looking at the configuration according to the invention in detail with reference to Figure 2,

The fire protection device by the electrical wiring is characterized in that it comprises a power supply unit 100, the blocking unit 200, the fuse box 300 and the detection unit 500.

Of course, the configuration as described above is not limited to this configuration for one embodiment, it is obvious that it can be changed in various forms by those skilled in the art.

The power supply unit 100 supplies power to the load 400 and may be formed of a battery.

The detector 500 is connected between the fuse box 300 and the load 400 and the breaker 200 to detect an amount of current applied to the load 400 through the fuse box 300 to be equal to or greater than the reference current. In this case, a control signal is applied to the breaker 200, and when the temperature of the wire is higher than the reference temperature, a control signal is applied to the breaker 200.

The blocking unit 200 is connected between the power supply unit 100 and the fuse box 300 is supplied to the load 400 by receiving a control signal according to the over-current or the reference temperature of the wire from the detection unit 500 or more To block.

Hereinafter, with reference to the drawings will be described in more detail the operation principle of the fire protection apparatus according to the present invention, the electrical wiring as described above.

2 and 3, when power is supplied from the power supply unit 100 to the load 400 through the fuse box 300, the sensing unit 300 is connected between the fuse box 300 and the load 400. The unit 500 detects the amount of current applied to the load through the fuse box 300, and also senses the temperature of the wire between the fuse box 300 and the load 400.

If the amount of detected current is greater than or equal to the reference current or the temperature of the wire is greater than or equal to the reference temperature, the control unit 500 outputs a control signal to the blocking unit 200.

The blocking unit 200 receiving the control signal from the sensing unit 500 cuts off the current flowing from the power supply unit 100 to the fuse box 300, and the driver of the equipment in the alarm unit 201 connected to the blocking unit 200. By alerting the user of the danger by sound or warning light, the load, that is, the function of preventing the fire light generated in the vehicle light in advance, and the warning light may be made of the LED light.

Although one preferred embodiment of the present invention has been described above, it is apparent that the present invention may use various changes, modifications, and equivalents, and may be applied in the same manner by always modifying the embodiment as appropriate.

Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the present invention prevents fire due to the electric wiring, and detects an overheating of the wiring due to an overload, cuts off the power supply before the coating is broken, and informs the driver of the overcurrent of the equipment through sound or warning. It is effective in preventing fire.
