Firefighting safety devices using electric devices in buildings and apartments}

The present invention relates to a firefighting safety device using electrical devices of buildings and apartments in the field of firefighting technology, and more particularly, to prevent children from playing around easily by increasing the security of the firefighting alarm system, and ventilation around landings in the event of a fire. Firefighting safety device using the electrical equipment of improved buildings and apartment houses to prevent fire from growing through flame suppression, and to block the elevator ride itself, especially in case of fire, to prevent secondary accidents caused by the fire. It is about.

In general, a fire alarm system receives a fire detection signal from a fire detection device installed indoors and a signal such as a switch that is pressurized to notify an emergency situation, and sends a signal to the disaster prevention center while notifying the outside of a fire or emergency situation with light or sound. It is a device that is configured to send a fire to the outside, and it consists of an alarm member and an alarm member and is installed in an alarm facility box.

That is, when a fire occurs in a building, the fire alarm system operates as a manual signal to the receiver by pressing the push button of the transmitter, and the signal automatically detected by the detector is automatically transmitted to the receiver alarm, and an alarm sound is generated from the alarm.

As shown in FIG. 1, the fire-fighting alarm device is installed inside and outside the alarm equipment box 10, and an alarm member 11 provided with a transmitter, a button, and a warning light on the front of the alarm equipment box 10 Is installed to be exposed, and the alarm bell member (B) operated by the alarm member 11 is electrically connected to the alarm member 11 and is installed inside the alarm equipment box 10 to generate a strong sound.

By the way, the cover of the alarm box 10 is not locked for management reasons, and if it is locked, it is impossible to manage all the keys of each of the countless alarm box boxes 10 such as apartment houses. (10) It has fallen into a state where it cannot be opened, so it is usually left unfastened.

For this reason, many damages have occurred, such as making an alarm sound while children and unhealthy teenagers play a lot of pranks on the landings, tear off the alarm member 11, or destroy the circuit by burning cigarettes.

In addition, when the alarm sound is generated from the alarm bell member (B) installed inside the alarm equipment box (10), the position of the alarm bell and the position of the sound hole formed on the cover are different, and some of the alarm sound generated from the alarm bell member (B) is As it hits the cover of the alarm equipment box (10) and reflects it, it cancels the alarm sound generated from the alarm clock member (B), and in other parts, the alarm sound transmitted to the outside of the alarm equipment box (10) through the sound hole is reduced, There is a problem in that it does not meet the fire safety standards that must be transmitted over 90db at a location 1m away from the center of (B).

In addition, it only sounds an alarm, but there is no function to extinguish a fire spreading through landing. In order to extinguish a fire, a person must open a fire hydrant and open a fire hose one by one, but it is virtually impossible for the general public who is busy evacuating in an emergency such as a fire to perform the fire extinguishing operation.

Moreover, in the event of a fire, I am in a hurry to board the elevator, but since the elevator causes a safety accident immediately when the electricity is cut off, it is necessary to shut off the occupant itself, and there is no such means, especially when evacuating by landing. When the heat fills the landing, it is difficult to evacuate and it is necessary to solve the problem of safety accidents.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The fire safety device using the electric device of the building and the apartment house according to the present invention includes an alarm box 100 as illustrated in FIG. 2.

The alarm box 100 has a rectangular box shape with an open front and is the same as an existing alarm box.

In addition, the alarm box 100 is provided with an alarm member 110 and a controller 120 for driving the alarm member 110 by receiving a fire signal as before.

In addition, a water supply control valve 300 that is opened/closed and controlled according to a control signal from the controller 120 is installed at one side inside the alarm box 100, and the water supply control valve 300 has an alarm box 100 It is configured to be connected to a branch pipe (not shown) branched from the fire hydrant 400 (see FIG. 5) provided below the hydrant to control supply and cut off of fire extinguishing water.

In addition, the first and second sole valves 210 and 220 are installed in-line at intervals on the inner upper side of the alarm box 100, and the first and second sole valves 210 and 220 are valves. It is a solenoid valve with a body (BOD) and a rocker (LOC) that appears and exits according to the energized state of electricity.

At this time, the controller 120 adapts commercial power, converts DC, and uses it as power required for control and driving, and the controller 120 controls the alarm member 110 as illustrated in FIG. 4. An alarm control controller (CTR) is connected, and a solenoid valve controller 200 that simultaneously controls the first and second sole valves 210 and 220 is connected, and an open/close controller (OCL) that controls the water supply control valve 300. ) Is connected.

That is, these alarm bell controller (CTR), sol valve controller 200, and open/close controller (OCL) are provided in the controller 120 and are electrically connected.

In particular, a 9V battery terminal 202 is further connected to the solenoid valve controller 200, wherein the 9V battery terminal 202 includes a terminal housing (HOS) installed on one side of the alarm box 100, and the terminal housing ( HOS) and elastically protruding from the elastic terminal (TR).

Here, as illustrated in FIG. 3, the 9V battery terminal 202 contacts the 9V battery for maintenance or when it is necessary to open the cover 130 of the alarm box 100 emergencyly in a non-fire situation. This is to enable the first and second sole valves 210 and 220 to be directly switched to an open state without a control signal from the controller 120 by energizing.

Therefore, an open terminal 134 is provided on one side of the cover 130 to maintain a energized state by contacting the elastic terminal TR.

In addition, a lock switch terminal 140 connected to the controller 120 is separately provided at one side of the alarm box 100, and the lock switch terminal 140 is also configured to be elastically protruded like an elastic terminal TR. It is configured to be connected to the one-touch lock switch 138 installed on one side of the cover 130.

That is, the lock switch terminal 140 is a terminal that controls only the operation of locking the first and second solenoid valves 210 and 220 through the sole valve controller 200 by providing only an ON signal, and the lock switch 138 ) Is a press-only switch, and when it is pressed and released once, it sends a current signal only once.Every time it is pressed, it sends a current signal to output a signal that changes the direction of always locking the first and second sole valves 210 and 220.

In addition, on both sides of the upper end of the surface where the cover 130 is in contact with the alarm box 100, cover latches 132 inserted above the lockers (LOC) of the first and second sole valves 210 and 220 are approximately ' It is protruding in the shape of a'.

In addition, the lower part engaging piece 136 vertically protrudes at the lower end of the side on which the cover engaging hole 132 is formed.

At this time, the reason for the need for the lower engaging piece 136 is that when the cover engaging hole 132 is inserted into the alarm box 100, the lower engaging piece 136 is simultaneously inserted outside the lower end of the alarm box 100. The upper and lower ends of the cover 130 are rotated to make it difficult to separate.

That is, the cover latch 132 is hung on the inner ceiling surface of the alarm box 100 while being inserted at a certain depth, and at the same time, the first and second brush valves 210 and 220 are inserted and hung, so it is easily lifted. It is not, but in that state, if the lower engaging piece 136 is fitted and caught on the lower outer surface of the alarm box 100 while being interviewed, complete locking occurs, so that it cannot be lifted and separated by a rotating method.

To this end, the alarm box 100 must be installed to protrude at a certain height, and must be configured not to be completely embedded in the wall.

Eventually, when the cover 130 is attached to the front of the alarm box 100, the cover latch 132 is inserted into the alarm box 100 and at the same time, the lower locking piece 136 is at the lower end of the alarm box 100. It is fitted outward to keep it completely locked.

In this state, when the lock switch 138 is pressed, the lock switch terminal 140 is energized, and the controller 120 controls the sol valve controller 200 so that the first and second sole valves 210 and 220 are operated in the locking direction. .

Then, the cover 130 is fixed in a completely locked state.

After this state, the controller 120 operates only when a detection signal is received due to the occurrence of a fire to open the cover 130, and other than that, it can be opened only through the 9V battery terminal 202.

In addition, when the controller 120 opens the first and second sole valves 210 and 220 due to a fire, the cover 130 reaches a state in which the fixing force is completely released, and the vibration of the alarm member 110 sounding at the same time, as described below. It is separated from the alarm box 100 by the fire extinguishing water pressure injected by the water supply control valve 300 and falls downward.

Therefore, the alarm sound of the alarm member 110 provides sufficient decibels for anyone to hear.

On the other hand, as shown in the example of Figure 5, a wall groove 510 is formed on one wall of the elevator 500 next to the fire hydrant 400, and the wall groove 510 rotates within a 90° range during a fire. A blocking bar 530 blocking the boarding of the elevator 500 is further provided.

At this time, the step motor 520 is fixed to the bottom surface of the wall groove 510, and the lower end of the blocking bar 530 is fixed to the motor shaft of the step motor 520.

Here, the step motor 520 is a motor that rotates forward and reverse within a 90° range, and is connected to the controller 120 to be driven and controlled.

However, when the blocking bar 530 is opened while being embedded in the wall groove 510, it is necessary to seal it not only for appearance quality but also for children to play.

To this end, in the present invention, a flexible plate 540 is further provided.

The flexible plate 540 is a kind of corrugated plate, the lower end is fixed to the lower wall of the wall groove 510, the upper end is fixed to the upper end of the blocking bar 530.

Therefore, when the blocking bar 530 is vertically erected and inserted into the wall groove 510, the flexible plate 540 is in a state in which the wall groove 510 is sealed, and the elevator 500 rotates by 90°. When folded horizontally to limit the boarding of the flexible plate 540, the wall groove 510 is opened while being folded together.

Therefore, the wall groove 510 can be safely sealed and smoothly operated.

In addition, the blocking operation of the blocking bar 530 is operated according to a control signal of the controller 120 that detects a fire.

On the other hand, on the upper wall of the elevator 500, a combustion extinguishing water sprayer 600 is further installed.

The smoke removal water injector 600 includes an injector housing 610 embedded in the wall so as to protrude to the outside, as shown in the example of FIG. 6, and the ventilation is built into the injector housing 610 and driven and controlled by the controller 120. A fan 620, a funnel-shaped spray guide 630 fixed to the protruding end of the sprayer housing 610, and a plurality of installations at intervals in the circumferential direction of the spray guide 630, and a water supply control valve 300 ) Through the spray hole 650 connected to receive the fire extinguishing water, and the fire extinguishing water assembled in the spray hole 650 to spray the fire extinguishing water in the form of a mist, and are discharged to the front by the blowing pressure of the ventilation fan 620 It includes a spray tooth cone 660 to guide it to cool.

Here, the opposite end of the injector housing 610 is installed so as to pass through the wall and communicate with the elevator moving space (not shown), but should not be exposed. This is because the elevator 500 should not interfere while elevating.

In addition, the reason for communication is that it must be able to suck and exhale air during blowing.

In addition, a fire extinguishing water supply pipe 640 is formed in the injection guide 630 in a radial direction, and the fire extinguishing water supply pipe 640 is connected to the discharge end of the water supply control valve 300 through a separate pipe.

In addition, the injection hole 650 is formed on the fire extinguishing water supply pipe 640.

In particular, the injection nipple 660 has a straight tube-shaped nipple body 662, a fastening portion 664 that is axially coupled at one end of the nipple body 662 and screwed to the injection hole 650, and the nipple In communication with the hemispherical nipple head 666 formed in a form stepped and expanded at the other end of the body 662, the hemispherical rectification chamber 668 formed inside the nipple head 666, and the injection hole 650 A supply passage (P1) formed in the nipple body 662 and connected to the rectification chamber 668, and the supply passage (P1) and the stepped jaw between the nipple body 662 and the nipple head 666 It includes an injection passage (P2) formed to be ejected through.

Accordingly, when the water supply control valve 300 is opened under the control of the controller 120 in case of a fire, the fire extinguishing water stays in the rectification chamber 668 of the nipple body 662 and passes the injection passage P2 in a state where the pressure is increased. It is sprayed or sprayed in the form of mist through.

Then, the mist-type spray is made toward the front of the spray guide 630, and at the same time, while the ventilation fan 620 is operated, a strong blowing pressure is discharged to discharge the mist-type spray to the front.

This blows out the high-temperature smoke that spreads over the landing, and at the same time lowers the temperature so that the evacuee does not get burned by the hot heat. In particular, the cooling function is improved due to the spraying of fire extinguishing water, so the ventilation effect is increased.

In this way, it is possible to increase the safety by double or triple.
