Description

MULTI-CONSENT FIRE SIMULATION APPARATUS FOR FIRE SAFETY EDUCATION}

The present invention relates to a multi-concentration fire simulation apparatus for fire safety education.

Elementary school students and preschool children can provide the causes of various safety accidents in the unconsciousness in the living environment due to the lack of knowledge and experience of various safety accidents.

In addition, elementary school students or preschool children lack the ability to cope with an accident even when a variety of safety accidents, the damage caused by the safety accidents can occur a lot.

In most cases, elementary school students and preschool children do not acquire the knowledge necessary for the risk of accidents and their ability to cope with accidents by training in a realistic situation for various safety accidents, but indirectly through books or video materials.

On the other hand, fire safety education aims to prevent fires and prevent human and property damage by extinguishing fires early by preventing fires and responding in case of emergency.

Accordingly, by simulating an environment similar to the actual fire occurrence, it is necessary to teach children, such as elementary school students, to feel the danger of fire as if it is real, and to teach them how to properly use and handle an electrical device having a fire risk.

On the other hand, according to various statistical data, the fire generated by the electrical device accounts for about one third of the fire generated in the building.

Among them, the fire caused by the overload or the leakage of the electric heating device is about 2/3, so the risk of fire caused by the incorrect use and handling of the electric device is serious.

Multi-outlets are a prime example of a fire hazard.

Multi-outlet is a device that supplies power by connecting a plurality of electrical and electronic devices by connecting to an embedded outlet provided in a building.

Therefore, overcurrent exceeding the rated current may flow through the multi-outlet. Overcurrent generates heat to the wire and the heat generated can cause a short circuit accident by lowering the dielectric strength of the wire sheath. Even if the overcurrent continues to flow, a short circuit may occur due to deterioration of the wire coating, which may cause a serious fire.

Prior art (KR2009-0117568A) related to the present invention discloses a power saving intelligent multi-outlet for fire prevention. The multi-concentrator according to the prior art is configured to operate to prevent damage to the multi-outlet and secondary accident spreading when the temperature of the multi-outlet reaches a dangerous temperature, and to cut off electricity in response to an overload, a short circuit and an overheat.

However, the multi-concentration disclosed in the prior art document is not provided for fire safety education, but is designed to lower the fire occurrence rate in actual use, and it is difficult to be used for fire safety education for children such as elementary school students.

Smoke simulation unit 300 is a device for discharging the steam in a set direction to simulate the smoke generated when the fire in the multi-conductor 200.

Specifically, the smoke simulation unit 300 includes a steam generator 310 for generating steam and a discharge passage part 350 for discharging the generated steam onto a position adjacent to the multi-conductor 200.

The steam generator 310 may be located inside the accommodation space 130 of the main body 100.

Although not shown separately, the steam generator 310 may include a water storage tank and a sealed case.

A water storage tank is a storage container that stores a set amount of water. For example, the water storage tank may have a box shape, a cylindrical shape, and other shapes, and store water supplied by a user. Water stored in the water storage tank is generated in the steam generator 310 by steam using at least one of the ultrasonic vibration method and the heating method.

The sealed case is a container having a sealed structure that forms an exterior of the steam generator 310. Such a sealed case has an overall sealed shape except for a portion connected to the discharge flow passage part 350, and may store and store water vapor generated through the steam generator 310 in an internal space.

The discharge passage part 350 serves to discharge the steam generated by the steam generator 310 located inside the main body part 100 to the rear of the multi-concentrator 200.

To this end, the inlet of the discharge passage 350 is connected to the steam generator 310, and the outlet of the discharge passage 350 is connected to the upper portion of the main body 100, that is, through the cover 120.

In particular, the outlet of the discharge flow path part 350 is located at a rear of the outlet at a predetermined distance from the multi-outlet 200. Accordingly, the water vapor may be sprayed upward from the rear of the multi-concentrator 200 to simulate the smoke generated when the fire is similar to the actual state.

The flame simulation unit 400 interlocks with the operation of the smoke simulation unit 300 at the rear of the discharge position of the water vapor to forward the light of the flame color (hereinafter referred to as 'flame light') (ie, the direction in which the water vapor is discharged). To emit light.

In this way, the flame light emitted from the flame simulation unit 400 can be widely spread while passing through the water vapor discharged from the front.

As a result, the flame simulation unit 400 may simulate the flame image similar to the reality, such as when a fire occurs in a multi-conductor which is actually used together with the smoke simulation unit 300.

As a specific example, the flame simulation unit 400 includes a light emitting housing 410 and a light emitting element 420.

The light emitting housing 410 is provided at the outlet of the discharge passage 350 and is located behind the discharge opening 3556 (see FIG. 2), which is a passage through which water vapor is discharged to the upper portion of the main body 100.

In addition, the light emitting housing 410 is separated from the cover 120 together with the fixing plate 420, thereby making it easy to clean and replace the cover 120.

The light emitting housing 410 has a front part 411 formed at the outlet (ie, the discharge opening) side of the discharge flow path part 350, a rear part 413 formed at the opposite side of the front part 411, and a front part 411. It is provided with a round cover portion 412 sealing between the rear portion.

형상으로 결합되어 외부와 차단되는 구조를 갖는다. The front part 411, the cover part 412, and the rear part 413 are formed at the top of the fixing plate 430.

It is coupled in shape to have a structure that is blocked from the outside.

Accordingly, the water vapor discharged from the front of the light emitting housing 410 is prevented from invading the inside of the light emitting housing 410, the circuit board for driving the failure of the light emitting device 420 or the light emitting device 420 is turned on and flashing Can prevent the malfunction.

In addition, the inner wall of the rear portion 413 of the light emitting housing 410 guides the flame light emitted from the light emitting element 420 toward the outlet (that is, the discharge opening) of the discharge passage 350 through which water vapor is discharged, thereby reflecting the light. The reflector 415 may be further provided.

Accordingly, the flame light emitted from the light emitting element 420 located inside the light emitting housing 410 emits light in a direction in which water vapor is discharged, thereby creating a visual atmosphere such as a flame generated by a real fire in the water vapor.

The controller 500 may be embedded in the accommodation space 130 of the main body 100, but is not limited thereto.

The controller 500 may control the smoke simulation unit 300 to adjust the discharge operation of the steam. In addition, the control unit 500 may control the flame simulation unit 400 to control the light emitting operation of the flame light on / off and to adjust the emission time.

To this end, the control unit 500 may further include a power supply circuit configuration for supplying power required for the operation of the smoke simulation unit 300 and the flame simulation unit 400.

The control unit 500 may further include a separate operation switch circuit configuration for individually on / off control of each of the smoke simulation unit 300 and the flame simulation unit 400. In addition, the control unit 500 may further include a control circuit configuration that is obvious to those skilled in the art.

In detail, the controller 500 may apply the first operation signal S1 to the steam generator 310.

The steam generator 310 receives the first operation signal S1 from the controller 500 to generate steam using water stored in the water storage tank. The water vapor may be discharged to the rear of the multi-outlet 200 through the discharge passage 350.

In addition, the controller 500 may apply the second operation signal S2 to the flame simulation unit 400 at an interval of a set time (for example, 3 to 5 seconds) after the application of the first operation signal S1. have.

The flame simulation unit 400 emits the flame light by receiving the second operation signal S2 from the control unit 500. The flame light unit 400 emits the flame light toward the water vapor discharged behind the multi-conductor, whereby smoke and flame are generated. The fire situation can be simulated as it is

The switch module 600 includes a main switch 610 (see FIG. 4) which commands power supply and operation signal input of the smoke simulation unit 300 and the flame simulation unit 400 through the control unit 500.

Unlike the control unit 500, the switch module 600 may be installed outside the main body unit 100.

If the switch module 600 is embedded in the receiving space 130 of the main body 100, such as the control unit 500, the user's ease of operation is reduced.

Therefore, the switch module 600 is preferably installed outside the main body 100.

As a specific example, the switch module 600 may be fixedly disposed on the cover 120 of the main body 100 (see FIG. 4). Accordingly, the user may perform fire simulation by operating the switch module 600 while visually monitoring the fire situation of the multi-outlet 200.

Meanwhile, the switch module 600 may further include an emergency shut-off sub switch 620 (see FIG. 4) together with the main switch 610 (see FIG. 4).

The emergency shutoff subswitch 620 (refer to FIG. 4) is configured to shut off power supply and operation signal input by the main switch 610 (refer to FIG. 4) in an emergency only by pressing a button.

The switch module 600 is disposed on the upper portion of the cover 120, and the user presses the main switch 610 exposed to the upper portion of the switch module 600 to command the operation of the fire safety training device 1000 multi-outlet simulation. can do.

When the main switch 610 is pressed, the control unit 500 supplies power to the smoke simulation unit 300 (more specifically, the steam generating unit) and the flame simulation unit 400, and the operations necessary for the respective operations. The signal S1, S2, see FIG. 1 is applied.

Referring to FIG. 5, the controller 500 first applies the first operation signal to the steam generator 310. Accordingly, the steam generator 310 generates steam using water stored in the water storage tank. In addition, the generated water vapor 710 is discharged to the rear of the multi-concentrator 200 to simulate a situation similar to the appearance of smoke generated in a similar fire.

Referring to FIG. 6, the control unit 500 applies a second operation signal to the flame simulation unit 400 after a set time elapses after the application of the first operation signal. Accordingly, the flame simulation unit 400 emits the flame light 720, by emitting toward the vapor 710 of the smoke form formed in the rear of the multi-conductor 200, the actual fire situation in which the flame is generated along with the smoke Copy like

Referring to FIG. 7, the control unit 500 may further control the output of the flashing light 730 flashing in a red color at a predetermined position together with the flame light 720 emitted through the flame simulation unit 400. Can be. In this case, the blinking light 730 may be selectively implemented, and may be used as a means for emphasizing the seriousness of the fire together with the water vapor 710 and the flame light 720.

As described above, according to the configuration of the present invention, by simulating a situation similar to the actual fire occurrence with respect to the electric fire accident generated by the overcurrent flow to the multi-conductor, students can safely experience a fire safety accident.

Specifically, the use of water vapor and flame light can quickly and safely simulate smoke and flames generated in the fire of a multi-conductor in a form almost similar to reality.

At this time, the water vapor is harmless to the human body and can be easily and quickly generated through water by ultrasonic or heating, etc., there is no need to use a chemical gas to simulate the smoke can be helpful for students safety.

And since the flame light is emitted from the rear of the water vapor, the light emitted from the light emitting device passes through the water vapor and diffuses into the same shape as the actual flame, so that the smoke and the flame appearing when the actual fire occurs can be visually experienced.

Further, the apparatus can be controlled to have a predetermined time interval between the operation of discharging water vapor and the operation of emitting light of flame light. Accordingly, when a multi-concentration fire occurs, smoke is generated first, and then a fire, that is, a fire situation in which a flame appears, can be simulated almost identical to the reality, thereby improving the educational effect of students.
