Description

Fire hydrant box for emergency}

The present invention relates to an emergency fire extinguishing box, and in particular, to an emergency fire extinguishing box that can be installed in a place where it is difficult for fire extinguishing vehicles to enter, and can quickly extinguish the fire in the event of a fire.

If a fire occurs, it is important to extinguish it early and minimize human and material damage. Accordingly, the building is equipped with sprinklers and fire extinguishers, and a large road is prepared adjacent to the building through which fire extinguishing vehicles can access the fire site.

However, in traditional markets where narrow alleys are formed and products are sold indoors/outdoors, it is difficult for fire suppression vehicles to enter the fire site when a fire occurs, and sprinklers cannot be installed outdoors. Even in these traditional markets, there are several outdoor/indoor emergency fire extinguishers, but it is difficult to cover the entire range of the traditional market, and as the fire hose drawn from the fire extinguisher box is deployed to the scene of the fire, the ground where various products are displayed It is difficult to quickly extinguish the fire because it has to pass through.

Recently, underground emergency fire extinguishers are being installed in places such as traditional markets where it is difficult to install indoor emergency fire extinguishers because fire suppression vehicles are difficult to pass by. An underground emergency fire extinguisher is a fire extinguishing device buried under a sidewalk or roadway. It can be installed in places where it is difficult to place an above-ground fire hydrant, and has the advantage of not causing inconvenience to the normal passage of cars or people. However, in order to install an underground emergency fire extinguisher, excavation work using heavy equipment is essential, causing inconvenience to merchants and citizens during the installation period, and work must be done only at night to avoid interfering with business. It can only get longer. In addition, even if an underground emergency fire extinguishing box is installed, it is not easy to deploy a fire hose that must pass through the ground, as is the case with outdoor/indoor emergency fire extinguishing boxes.

As an example, as shown in FIG. 2, the fire extinguishing box main body (A) can be installed on the wall of a building located near a narrow alley, and as another example, as shown in FIG. 3, the fire extinguishing box main body (A) can be installed in a conventional fire extinguishing box body (A). It can be installed to be supported by pillars erected on both sides of a market entrance or alley. As another example, as shown in FIG. 4, the fire extinguisher main body (A) can be installed to be supported by a single pillar erected like a street lamp in an alley of a traditional market or on one side of an indoor traditional market.

As described above, the fire extinguisher body (A) in the present invention is installed in the air and away from the ground, so it is free from various restrictions of conventional outdoor/indoor emergency fire extinguishers and underground emergency extinguishers, making it difficult for fire extinguishing vehicles to enter, such as in traditional markets. It can be easily installed in difficult places.

The fire hose 100 wound within the fire box main body (A) installed in the air is automatically released when a fire occurs and is drawn downward as shown in FIG. 5. Accordingly, it is possible to minimize the deployment of fire hoses through the ground to the fire site of a place where products are displayed on the ground while forming a narrow and complex alley like a traditional market, enabling rapid initial fire extinguishment.

As the fire hose 100 is automatically withdrawn, a fire detection sensor may be provided in the fire box main body (A) so that the fire hose 100 is automatically withdrawn when a fire is detected through the fire detection sensor. , Even when the fire hose 100 is not needed depending on the scale of the fire, etc., the fire hose 100 can be automatically pulled out. To prevent this, it is automatically released by the user's operation according to the occurrence of a fire and is drawn downward. It is desirable to be configured. As an example, when a fire occurs that requires the fire hose 100, the user can press the withdrawal button on the switch 840 provided on the lower side of the fire box body (A) installed in the air to cause the fire hose 100 to be drawn out. Additionally, the switch 840 is provided with a return button so that when fire suppression is completed, the fire hose 100 can be automatically wound by the user pressing the return button.

And, as shown in FIGS. 1 and 5, an inlet 710 through which the fire hose 100 can be drawn out may be formed in the fire box main body (A), and the fire hose 100 can be pulled out downward. Considering this, it is preferable that the inlet 710 is formed on the bottom of the fire extinguisher main body (A). The entrance 710 of the fire box main body (A) is provided with an opening and closing cover 720 that can open or close it, and the entrance 710 is normally closed by the opening and closing cover 720 to prevent rain, snow, dust, etc. It is possible to prevent foreign substances from entering the interior of the fire extinguisher main body (A). In addition, the opening/closing cover 720 provided at the entrance 710 is preferably configured to be automatically operated by a user's operation in the event of a fire to open the entrance 710.

As described above, the fire box main body (A) with the inlet 710 formed on the bottom may have the front and rear widths larger than the upper and bottom widths due to the size and arrangement of the components provided inside. You can. When the fire extinguisher box body (A), which is formed to have a long vertical width in this way, is installed in the air, it may interfere with the passage of vehicles, etc., and normally, as shown in FIG. 6A, the entrance 710 is located at the front or rear. It can be placed in a rotated state. This fire extinguisher box body (A) may be rotated so that the inlet 710 faces downward as shown in FIG. 6B when the user operates to withdraw the fire hose 100 in the event of a fire. This is useful when the fire box main body (A) is installed in a place such as a tunnel where vehicles of various heights pass.

Meanwhile, the fire box main body (A), as shown in Figures 1 and 5, allows water to be sprayed through the fire hose 100 when the fire hose 100 is pulled downward by the user's operation. A pump 300 and a main valve 400 may be included therein.

The pump 300 is connected to the first supply pipe 200a, which forms a flow path for supplying water from the outside, and is connected to the second supply pipe 200b, which forms a flow path for discharging water to the fire hose 100. , When operating, water can be supplied from the outside through the first supply pipe (200a) and sent to the fire hose (100) through the second supply pipe (200b). The main valve 400 is provided on the first supply pipe 200a and can control the flow of water to the pump 300. For example, when the main valve 400 is closed, water flow to the pump 300 may be blocked, and when the main valve 400 is opened, water flow to the pump 300 may be permitted.

Therefore, as shown in FIG. 5, when the fire hose 100 is pulled downward by the user's operation, the main valve 400 is automatically opened and the pump 300 is driven to spray water through the fire hose 100. A possible state can be achieved.

And, when the fire suppression is completed by spraying water through the fire hose 100, the fire extinguisher box body (A) performs residual water treatment as shown in FIG. 7 in order to effectively remove residual water present in the fire hose 100. It may further include a valve 500.

The residual water treatment valve 500 may have at least three flow paths and, for example, may be configured as a 3-way valve. Specifically, the residual water treatment valve 500 may include a water inlet 510, an outlet 520, and an air inlet 530 formed at the ends of each of the three flow paths, as shown in FIG. 8. The water inlet 510 may be connected to the pump 300, and the outlet 520 may be connected to the second supply pipe 200b. Additionally, the air inlet 530 may be formed by branching between the water inlet 510 and the outlet 520, and may be provided to be exposed to the outside of the fire extinguishing box main body (A).

It can be controlled to communicate. Therefore, when the fire hose 100 is pulled out and water is supplied to the fire hose 100 according to the user's operation in the event of a fire, the outlet 520 communicates with the water inlet 510 as shown in FIG. 8A. In addition, the outlet 520 can be controlled so that it does not communicate with the air inlet 530.

And when the fire situation is over, the operation of the pump 300 is stopped and the main valve 400 is closed, the outlet 520 communicates with the air inlet 530 as shown in FIG. 8B, and the outlet 520 is It can be controlled so as not to communicate with the water inlet 510. As a result, air flows from the air inlet 530 to the outlet 520, allowing residual water to escape to the outside during the process of winding the fire hose 100 into the fire box main body A.

Meanwhile, the fire box main body (A), as shown in Figures 2 to 4, is equipped with an LED module on at least one of the front or back to enable the user to easily know the location of the emergency fire box or to convey various information. An electronic signboard 610 including may be provided. As the electronic sign board 610 operates, heat is generated from the LED module, and the heat may be configured to be emitted into the fire extinguisher main body (A).

For example, as shown in FIG. 9, a heat sink 620 may be provided on the adjacent rear side of the LED module of the electronic sign board 610 to collect heat generated from the LED module and radiate it toward the rear. In addition, considering that the main valve 400 is normally closed and water exists only up to the first supply pipe 200a, in order to prevent freezing of the first supply pipe 200a in winter, the vicinity where the first supply pipe 200a is placed This allows heat dissipation to be concentrated. For this purpose, as shown in FIG. 9, the fire box main body (A) has a heat dissipation guide wall 630 built at a predetermined distance from the heat sink 620, excluding the vicinity where the first supply pipe 200a is arranged. You can.

In this way, through the heat generated from the LED module, it is possible to effectively prevent pipes, etc. from freezing and bursting in winter, and since the water present in the first supply pipe (200a) does not freeze, the fire hose (100) can be immediately used in the event of a fire in winter. Fire suppression is possible through

Meanwhile, the fire box main body (A) is controlled so that the winding and unwinding of the fire hose 100, as well as the operation of the pump 300, the main valve 400, and the residual water treatment valve 500 can be automatically performed upon user operation. It may further include a control box 820. In addition, the fire box main body (A) may further include a display board controller 830 that controls the operation of the display board 830. In addition, even if a power outage occurs, a charging inverter 810 may be further included so that the above-described internal structure of the fire box main body (A), emergency lighting, fire alarm, etc. provided in the fire box main body (A) are operated.
