Abstract

PURPOSE: An automatic fire extinguishing device for an engine room of a bus is provided to detect and extinguish fire regardless of the size of an engine. CONSTITUTION: An automatic fire extinguishing device for an engine room of a bus comprises: a detection unit(100) which is formed inside an engine room and senses heat; a nozzle unit(200) which is combined with the inner upper part of the engine room and sprays fire extinguishing powder; a fire extinguishing unit(300) which provides fire extinguishing powder to a nozzle unit; and a controller(400) which controls the fire extinguishing unit.

Description

The extinguishing fire apparatus for engine room ofvehicle}

The present invention relates to an automatic fire engine engine fire extinguishing apparatus for a bus, and to an automatic fire engine fire extinguishing apparatus capable of extinguishing a fire at an early stage by detecting a fire accurately in a vehicle equipped with a large engine.

In general, automobiles are classified into various types such as passenger cars, buses, vans, and the like, and engines using fossil fuels such as gasoline or diesel are installed as driving sources, and electric motors driven by electricity of fuel cells or batteries may be installed.

Such an automobile may cause a fire due to an overheating of the engine or an external impact. For example, a problem in the electric system may be caused by an electric spark in which the engine is overheated or leaks while fuel is leaking from any part of the fuel system. Occurs when the car is fired, even when the car crashes.

In the related art, a fire extinguisher is provided in a vehicle to prepare for a fire occurrence of a vehicle, and a driver directly extinguishes the fire by using a fire extinguisher.

However, in the event of a traffic accident, passengers, including the driver, cannot escape from the car normally, and the fire extinguishers in the car cannot be used normally, so that the fire of the car can endanger human life. The fire in a position that is urgent but difficult to deal with was inevitable, and the fire in the state where the driver was distracted had the problem of fatal injury.

Although a number of systems for detecting and coping with fires of engines have been disclosed, it is difficult to accurately detect a fire when a large engine such as a bus is mounted, and there is a problem in that it is difficult to completely extinguish a fire due to a narrow structure for injecting extinguishing fluid.

The present invention has been made to solve the above problems, the bus engine room automatic fire extinguishing apparatus capable of detecting and extinguishing fire completely even when the driver loses his mind, even when a large engine such as a bus is mounted. To provide.

The present invention for achieving the object as described above in the bus provided with an engine room, the detection unit is formed inside the engine room for detecting heat, and the nozzle is formed on the upper side of the engine room in the fire extinguishing powder is injected And a fire extinguishing unit for providing fire extinguishing powder to the nozzle unit, and a control unit for receiving the signal of the detection unit to control the fire extinguishing unit.

The nozzle unit may include a pipe installed at an upper side of the engine room, and a plurality of nozzles communicating with a lower side of the pipe.

The detector is located above the pipe, and is bent several times in a zigzag.

And, an alarm unit is installed in the bus, characterized in that controlled by the control unit.

As described above, in the event of a fire in the engine room due to an overheating or accident of the engine or a leaking electric spark, the fire and the fire position are detected, and the fire is moved to the exact position where the fire occurs to extinguish the fire. It can protect the lives of passengers, including drivers, and reduce fatal casualties.

1 is a perspective view showing an automatic fire engine engine fire extinguishing device according to the present invention.
2 is an embodiment in which the fire extinguishing unit according to the present invention is installed in the engine room.

Hereinafter, with reference to the accompanying drawings will be described a bus engine room automatic fire extinguishing device.

1 is a perspective view showing an automatic fire engine engine fire extinguishing device according to the present invention, Figure 2 is an embodiment of the fire extinguishing unit according to the present invention is installed in the engine room.

As shown in Figure 1 and 2, the detection unit 100 is formed in the engine room 50 of the bus for detecting heat, and a nozzle formed in the upper side of the engine room 50, the fire extinguishing powder is injected To the control unit 400 to control the fire extinguishing unit 300, the fire extinguishing unit 300 for providing a fire extinguishing powder to the nozzle unit 200, and the signal from the detection unit 100 is received. Is done.

Hereinafter, each configuration will be described in detail.

The detection unit 100 detects heat when a fire occurs due to an overheating or external impact of the engine 10 inside the engine room 50.

In addition, the detection unit 100 is formed above the engine room 50. This is because the heat generated by the fire rises by convection and radiation.

The nozzle unit 200 is formed above the engine room 50 so that the fire extinguishing powder provided by the fire extinguishing unit 300 is injected.

The nozzle unit 200 according to the present invention includes a pipe 210 installed at an upper side of the engine room 50 and a nozzle 220 communicating with a lower side of the pipe 210.

Here, the pipe 210 is a coupling bracket 250 is formed on one side in order to be installed in the upper side of the engine room (50). Thus, the coupling bracket 250 is fastening hole 60 is formed on the upper side of the engine room 50, it is coupled to the fastening hole 60 by a bolting coupling.

Here, the nozzle 220 is communicated to the lower side of the pipe 210, the extinguishing powder provided by the fire extinguishing unit 300 is injected.

Therefore, since the nozzle unit 200 can be installed in the entire upper side of the engine room 50, fire extinguishing is possible even if a fire occurs in any part of the engine 10 operating inside the engine room 50. .

The fire extinguishing unit 300 is to provide a fire extinguishing powder to the nozzle unit 200, flexible and extinguishing pipe 310 communicated to the pipe 210, the powder chamber 320, the extinguishing powder is stored, and the control unit It is composed of an air chamber 330 for providing air to the extinguishing powder is moved to the digestive tract 310 by 400.

When the fire occurs in the engine 10, the control unit 400 receives the signal from the detection unit 100 to operate the fire extinguishing unit 300 to extinguish the fire.

When the signal value received from the detection unit 100 is equal to or greater than the input temperature value, the control unit 400 'ON' the air chamber 330 to provide air to the powder chamber 320, and extinguish powder This is supplied to the nozzle unit 200.

Preferably, the detection unit 100 is located above the pipe 210, and may be bent a number of times in zigzag. In the case of a large vehicle, the engine 10 is also large because the size of the engine room 50 is large. Accordingly, the detection unit 100 may be bent a number of times in a zigzag manner above the pipe 210 in order to cope with a fire of all ranges.

Preferably, the alarm unit 500 is installed inside the bus, when the fire occurs in the engine 10 is controlled by the control unit 400 may be configured to inform the passengers of the fire situation.

As described above, it is a basic technical idea to manufacture a vehicle equipped with a large engine so as to respond to a wide range of fires by mounting a detection unit capable of detecting the full range of the engine, which is merely an example, and in the art Those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom, and the true technical protection scope of the present invention should be defined only by the appended claims.
