Description

Apparatus for fire training {APPARATUS FOR FIRE-TRAINING}

The present invention relates to a device for fire drills.

In general, fire drills are not only training for accidents that may occur in the event of a fire, but also training to effectively extinguish the fire. to effectively respond to firefighting.

However, as fire drills are still conducted with actual flames ignited outdoors, such as on a wide flat land such as a playground, safety problems such as injuries to the trainee's body due to the sparks ignited during training are inherent. There is a problem of causing environmental pollution by smoke and gas caused by ignition. In addition, due to safety concerns, there was a problem that teenagers and children were not able to familiarize themselves with fire drills from a young age as only evacuation tips in the event of a fire were educated.

Existing educational equipment to improve this problem is a material for education and training that simply sprays a fire extinguishing agent on a flame-shaped target. However, this technology could not produce the feeling of a living flame by providing a target in the form of a still picture, and it was not possible to automatically evaluate the fire extinguisher user's ability and give feedback when spraying the extinguishing agent. Therefore, there is an urgent need for the development of a device capable of more realistically training a sense of presence in the event of a fire.

On the other hand, in the case of fire extinguishers used for education, fire extinguishers manufactured for fire extinguishing are mainly used as they are, so they are small in size, so it is an essential part in the education of fire extinguishers such as safety pins and pressure gauges for remote trainees in fire education and training conducted in public institutions such as schools. It was difficult to see them well, and if the conventional fire extinguisher was enlarged with the same structure in order to improve it, there was a problem that it became too heavy to carry or use.

An embodiment of the present invention improves visibility by increasing the volume of the fire extinguisher through air injection during education, and reduces the volume of the fire extinguisher through air discharge upon completion of education to facilitate storage and movement, and reproduces it through a fire model plate The purpose of this is to provide an educational fire extinguishing device that can improve the sense of presence by changing the appearance of the fire flame as the fire extinguishing training progresses.
