Description

Foam injection underground emergency fire extinguisher system {FOAM INJECTION UNDERGROUND FIRE EXTINGUISHER SYSTEM}

The present invention relates to a foam injection underground emergency fire extinguisher system.

In general, firefighting equipment is provided in each building in order to prevent property damage and human damage due to a fire in the building. In buildings and apartments, indoor fire hydrants are installed at specific locations on each floor in accordance with the Act on the Installation, Maintenance and Safety Management of Fire Fighting Facilities, and outdoor emergency fire extinguishers play a very important role in extinguishing fires quickly and accurately. .

The fire hydrant may include a fire hydrant equipped with a water outlet, a fire hose of a size suitable for the size of the building, and a pipe window that directly sprays water on the flame. .

The above-mentioned outdoor emergency fire extinguisher box has recently been installed in traditional markets or residential areas where multi-family houses are densely populated. There is a fire hydrant installed, but a fire hose including a pipe window that directly sprays water is not installed, so the initial response to fire is insufficient. In order to solve this problem, an outdoor emergency fire extinguisher box that can store a fire hose including a pipe window is being installed in an existing fire hydrant. Compensation for damage caused by

In addition, a suitable extinguishing method and extinguishing liquid should be used according to the type and characteristics of the fire, and an extinguishing liquid containing water, acid/alkali, fortifying liquid, halogen compound, carbon dioxide, powder, etc. may be used depending on the type of extinguishing agent.

In addition, the second connection line 164 is coupled to the water supply line 150 by inclining toward the direction in which the fire extinguishing water proceeds in order to prevent the reverse flow of the fire extinguishing water from the water supply line 150 to the second connection line 164 . , the end is inserted into the inside of the water supply line 150 can be coupled. More specifically, the second connection line 164 is coupled to the water supply line 150 so as to be inclined toward the direction in which the fire fighting water proceeds, one end is connected to the lower side of the storage unit 140 , and the other end is connected to the water supply line 150 . ) can be inserted into the The other end of the second connection line 164 is inserted into the water supply line 150 so that the fire extinguishing water passing through the water supply line 150 and the fire extinguishing agent 142 passing through the second connection line 164 are evenly mixed. can make it happen

Therefore, the fire fighting water moving from the water supply line 150 to the first connection line 162 goes through the first connection line 162 , the storage unit 140 , and the second connection line 164 to the water supply line 150 . It may be introduced again, and in this process, the fire extinguishing agent 142 in the storage unit 140 may be mixed with the fire extinguishing water to form a fire extinguishing foam. Here, the storage unit 140 has a first connection line 162 on the upper side and a second connection line 164 on the lower side, so that the fire extinguishing water and the extinguishing agent 142 can be designed to move in one direction by gravity. have.

Also, as shown in FIG. 2 , the connection line 160 may have a smaller diameter than the water supply line 150 . In the case of a fire that does not require the use of the extinguishing agent 142, the connection valve 166, which will be described later, is closed to block the flow of extinguishing water to the connection line 160, so the connection line 160 supplies the extinguishing agent 142 with water. It can be transferred to the line 150 and formed with a diameter that can flow an amount of fire extinguishing water that can form a fire extinguishing foam.

As shown in FIG. 2 , the water supply valve 152 may be installed in the water supply line 150 to control the movement of fire extinguishing water. More specifically, the water supply valve 152 may be installed to extend outwardly from the water supply line 150 disposed inside the housing 200 so that a user can use the water supply valve 152 outside the housing 200 .

As shown in FIG. 2 , the connection valve 166 is installed on the connection line 160 to control the movement of fire water between the water supply line 150 and the storage unit 140 , and more specifically, the connection The valve 166 may be formed on the second connection line 164 to control the movement of fire extinguishing water.

As shown in FIG. 1 , the hose 170 may spray the fire extinguishing foam formed by mixing the fire extinguishing water and the fire extinguishing agent 142 . More specifically, the hose 170 has one end connected to the water supply line 150 to receive fire extinguishing water, and fire extinguishing water to the other end, and the other end of the hose 170 is coupled with a fire extinguishing tube window to receive fire water. The spraying intensity of the can be adjusted.

As shown in FIG. 1 , the reel unit 180 is installed inside the housing 110 and a hose 170 can be wound around the outer circumferential surface, and more specifically, the reel unit 180 is the inner surface of the door unit 120 . A reel body 182 that is formed in a cylindrical shape and around which the hose 170 is wound around an outer circumferential surface, and a reel support 184 coupled to the inner surface of the door unit 120 to support the reel body 182 . may include
