FIREFIGHTING DEVICE HAVING FIRE HOSE FIELD OF THE INVENTION [0001]

FIELD OF THE INVENTION The present invention relates to a fire fighting apparatus having a fire hose that is easy to use.

Generally, fire fighting apparatuses are used to suppress fire, and fire fighting apparatuses widely used are fire hydrants, fire extinguishers and fire trucks.

Fire hydrants and fire brigades of these fire extinguishers use high pressure water supplied from the waterworks as fire fighting water to suppress the fire, and fire trucks use water stored in the fire fighting water tank as fire fighting water.

On the other hand, a fire hose having a long length is folded and folded in the inside of the fire hydrant, and then it is stored on the floor of the fire hydrant.

However, hygienic management is difficult due to the occurrence of mold in the folded part folded during storage for a long time, and it is difficult to suppress the fire promptly as the fire hose is partially broken due to the folded part being cut during the storage for a long time.

A conventional technique for solving the above problems is Korean Patent No. 10-1351939 (fire-extinguishing box equipped with a fire-fighting fire hose), and a fire-fighting hose is wound thereon and stored in a fire hydrant .

However, in the conventional technique, there is an easy aspect in that the fire hose can be quickly unwound and wound. However, there is a problem that the fire hose is twisted in the process of winding the fire hose using the bobbin.

On the other hand, such a fire hydrant is advantageous in that it is a piece-wise function, that is, a fire hose is hoisted and stored. However, there is a problem in that it is difficult to cope with the motion wave or leakage by frozen water.

The water sensing sensor 51 is a known sensor and is installed inside the water collecting tank 24 in the case of this embodiment to sense the water leaking from the fire pipe P and collect it in the water collecting tank 24, As shown in FIG.

The notification means 52 is a member in which a warning light and a speaker are combined and is installed on the lower surface of the water collecting tank 24 in the case of the present embodiment and is controlled by the control unit 70 to output warning light Sound).

The protective cover 53 is detachably provided on the lower surface of the water collecting tank 24 and functions to protect the reminding means 52 from external force.

Particularly, a plurality of holes are formed in the protective cover 53 so that the sound of the notification means 52 can be emitted to the outside.

For example, when water leakage occurs from the fire-fighting pipe P, the water leaking through the fire-fighting pipe P is collected in the water-collecting tank 24, and the water- And the notification means 52 operates the water sensing sensor 51 to emit light and a warning sound to the outside.

Therefore, the manager can quickly dispatch to the site through the lightening and warning sound to perform the maintenance work, which is advantageous in that the maintenance becomes very convenient.

1 and 3 to 7, the freeze preventing unit 60 includes a temperature sensor 61, a heater 62, and a flame deflecting member 63. In the present embodiment, And functions to prevent the freezing water flowing along the fire pipe (P) from freezing by applying heat to prevent freezing.

The temperature sensor 61 measures the temperature of the fire-fighting pipe P and outputs the measured temperature to the control unit 70.

The heater 62 is an electric heater and is wound around the circumference of the tube 21 in the case of the present embodiment to apply heat to the tube 21.

The flame deflecting member 63 is detachably attached to the tube body 21 to cover the heater 62 to protect the heater 62.

The flameproof member (63) is provided with a Velcro tape and can be easily and easily installed on the tube body (21).

According to the present embodiment, the temperature sensor 61 provided in the fire-fighting pipe P measures the temperature in real time and outputs the measured temperature to the control unit 70. The control unit 70 reads the temperature value from the temperature sensor 61 And the heater 62 is operated and controlled by the control unit 70 to apply heat to the tube body 21 to prevent the freeze wave from being generated.

The heater 62 may be provided on the circumferential surface of the tube 21 but may be provided on the fire pipe P as required and the temperature sensor 61 may be provided on the fire pipe P, it is also possible to directly measure the temperature of the water of fire fighting water provided inside the fire-fighting pipe P, if necessary.

The water sensing sensor 51 and the notifying means 52 and the temperature sensor 61 and the heater 62 are operated by receiving external power through the controller 70.

1 and 5, the controller 70 receives a sensing signal from the water sensing sensor 51 and controls the operation of the notifying means 52. The controller 70 receives a temperature value from the temperature sensor 61, And when the temperature is lower than the set temperature, the heater 62 functions to control the operation.

The control unit 70 supplies the power received from the outside to the water sensing sensor 51, the notification unit 52, the temperature sensor 61, and the heater 62.

Hereinafter, the operation of the present invention will be described.

First, when a fire occurs, the user pulls out the fire hose 30 accommodated in the fire extinguisher box 10 and then opens the valve V to extinguish the fire. .

First, when the fire hose 30 accommodated in the fire extinguisher box 10 is pulled out to the outside, when the bobbin 42 is pulled forward, the length of the multi-stage rod 41 is increased along the bobbin 42, At the same time, the railing 43b fixed to the multi-stage shaft 41 via the support portion 43a is slid along the guide portion 43c, and thus the fire hose 30 wound around the bobbin 42 is moved, Is exposed to the outside.

After the fire hose 30 wound on the bobbin 42 is released, fire water is injected in the direction of the fire so as to rapidly suppress the fire.

When the fire is extinguished, the fire hose 30 may be wound around the bobbin 42, and then the bobbin 42 may be pushed into the fire extinguisher box 10 and stored.

On the other hand, as shown in FIG. 6, when a fire pipe (P) generates a hole (or crack) due to aging or external impact, or when leakage occurs at the joint portion, the fire water leaking from the fire pipe (P) (P), and is gradually collected in the water collecting tank (24) provided on the circumferential surface of the tube body (21).

The water sensing sensor 51 senses the fire water thus collected and outputs the sensed water to the control unit 70. The control unit 70 receives the sensing signal to operate the notifying means 52, And is operated by the control unit 70 to emit light and warning sound to the outside.

Therefore, the manager can quickly dispatch to the site through the lightening and warning sound to perform the maintenance work, which is advantageous in that the maintenance becomes very convenient.

On the other hand, when the temperature of the fire-fighting pipe P is suddenly lowered, the freezing prevention unit 60 detects it and outputs it to the control unit 70.

More specifically, the temperature sensor 61 constituting the freezing prevention unit 60 measures the temperature of the fire-fighting pipe P in real time and outputs it to the control unit 70, Receives the temperature value from the temperature sensor 61, and compares it with a predetermined value.

At this time, if the temperature value measured by the temperature sensor 61 (for example, room temperature 6 ° C) is larger than a predetermined temperature value (for example, room temperature 5 ° C), the controller 70 does not operate the heater 62, The control unit 70 operates the heater 62 if the measured temperature value is lower than the measured temperature value (e.g., room temperature 4 ° C).

The heater 62 is operated by the controller 70 to generate heat, and heat generated by the heater 62 is transmitted to the inside of the tube 21 and the surrounding water, thereby preventing the fire pipe P from being frozen.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is natural.
