Description

{Alarm devices for fireman}

The present invention relates to an alarm device for notifying a user or another firefighter of a danger signal, and more particularly, to an alarm device for firefighters which is excellent in heat and waterproof functions and in which the alarm module is detachable, will be.

Generally, firefighters dispatched on the spot when a fire occurs are spraying water through the hose from the outside to suppress the fire. When there are injured persons or patients inside the fire site, they enter the fire scene and rescue people.

However, there is a risk of fire at the fire site and the toxic gas generated by the high temperature, and the structure weakened by the high temperature may collapse. Therefore, the fire brigade entering the fire department may suffocate, burn or burn, There is a lot of work to be done on the structure of the fire brigade. However, there is a problem in that it is difficult to rescue the firefighters who have been injured in a timely manner because it is difficult to identify the location due to smoke or the like at the accident site.

In order to solve such a problem, various methods have been sought in the past, and one of these uses wireless. In other words, a firefighter at the fire station carries the radio transceiver, reports the situation to the rescue headquarters installed outside, and, if a dangerous situation arises, contacts the rescue headquarters using a radio transceiver, To other firefighters using a wireless transceiver.

However, this method has no effect when suddenly buried or suffocated by consciousness, such as a sudden burial or a suffocation by a dangerous firefighter having a certain consciousness and having to contact the rescue headquarters with his / her status and location.

Furthermore, because the radio transceiver is composed of very weak electronic circuits at high temperatures, the radio transceiver is often disabled due to the high temperature at the fire site.

In order to overcome such a problem, the Registration Practical Utility Model No. 20-0272435 detects and warns that a firefighter dispatched to a fire site falls into an unstable state due to a gas suffocation or unexpected accident, A portable safety alarm device for a firefighting team "which can detect the expected failure state of the safety alarm device by means of a warning signal and thereby warn the safety of the fire scene.

However, the above-mentioned alarm device has a limitation in effectively notifying dangerous signals to other firefighters in an urgent situation of suppressing a fire, has a problem of insufficient heat resistance and waterproof function, and is easily separated and lost due to wearing with a clip.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an alarm device for a firefighter which further enhances safety by allowing the user and other firefighters to recognize a danger signal wirelessly.

It is another object of the present invention to provide an alarm device for a firefighter which is constructed so that an alarm module can be detached and removed, thereby facilitating replacement and use.

The alarm device for firefighters according to the present invention comprises a body coupled to a part of a fire fighting apparatus of a firefighting team, a detachable battery coupled to the inside of the body for receiving a danger signal wirelessly, And a protective cover which is made of semi-transparent material and is heat-resistant and water-proof, is connected to the body by sealing the alarm module, A plurality of first rotation protrusions, a plurality of fitting protrusions, and a plurality of vertical grooves are radially formed on an outer circumferential surface of a lower side, an upper side and a central side of the module coupling ring, The one rotation protrusion is coupled to the first guide portion formed on the inner circumferential surface of the body, and the fitting protrusion and the vertical groove are formed on the inner peripheral surface of the protective cover And are respectively coupled to the fitting groove and the vertical projection formed.

According to the fire alarm system of the present invention, when a danger signal is received by a wireless signal, the user and other fire fighters can recognize the danger signal and emit light promptly so that they can quickly evacuate.

In addition, since it is constructed so as to be firmly coupled to the outside of the fire fighting clothing of the firefighter, particularly to the back region, it is easily recognized by the eyes of other firefighters, and the portable and use is more convenient.

Further, since the alarm module is constituted by a detachable type which is simply fixed or separated by rotation, there is an advantage that it can be easily replaced when the battery is replaced or broken.
