Description

{APPARATUS FOR DISTRIBUTING FIRE WATER FOR FIRE HYDRANTS}

The present invention relates to a fire water distributor for fire hydrants.

Generally, fire hydrants are installed within buildings as fire extinguishing equipment. The fire hydrants currently installed have various structures depending on the size and purpose of the building. Representative types include indoor fire hydrants and hose reel fire hydrants. A hose reel fire hydrant is a structure in which a fire hose is wound around a reel device.

In relation to this, Korea Registered Utility Model No. 20-0396605 describes a fire water distributor for a fire hydrant, a hose reel in which a fire hose is wound on a reel, and an indoor fire hydrant in which fire hoses are stacked and stored, each supplying fire water through the distributor. It is configured so that it can be used, and the distributor is configured with a connector at one end, a first distribution port at the other end, and a second distribution port at the center, so the handling and use of the fire hydrant is convenient and easy for anyone. A fire water distributor for fire hydrants is being disclosed that is simple/easy to use and can be freely selected to use an indoor fire hydrant or a hose reel fire hydrant depending on the size or situation of the fire.

According to the above technology, a hose reel hydrant in which a fire hose is wound on a reel, and an indoor hydrant that has a large diameter of the fire hose, supplies/sprays a large amount of fire extinguishing water at high pressure, and is easy to extinguish a fire from a distance can be used at the same time. It is efficient and economical, and the fire hydrant is convenient to handle and use, and anyone can use it easily and simply. Depending on the size or situation of the fire, you can freely choose to use an indoor fire hydrant or a hose reel fire hydrant. Therefore, there is an effect of improving fire extinguishing efficiency.

Typically, when a fire occurs, these fire hydrants help extinguish the fire by aiming the spray nozzle of the hose reel or fire hose in the direction where the fire occurred and spraying fire extinguishing water. However, due to its weight, a hose reel or fire hose filled with fire extinguishing water is not only difficult for the elderly or young children to lift, but also difficult to aim the spray nozzle of the hose reel or fire hose in the desired direction.

Therefore, in the past, when only the elderly or young children were around a fire hydrant, it was difficult to extinguish a fire using it.

Figure 1 is a perspective view of a fire hydrant equipped with a fire water distributor for a fire hydrant according to an embodiment of the present invention, and Figure 2 is a cross-sectional view of a fire hydrant equipped with a fire water distributor for a fire hydrant according to an embodiment of the present invention. Figure 3 is a cross-sectional view of a fire water distributor for fire hydrants according to an embodiment of the present invention.

Referring to Figures 1 to 3, a fire water distributor 100 for a fire hydrant according to an embodiment of the present invention includes a main valve 110 and a fire water distribution pipe 200.

The main valve 110 opens/closes the fire extinguishing water inflow path connected from the fire extinguishing water supply line 20 to the extinguishing water distribution pipe 200. To this end, the main valve 110 may be provided with a handle as illustrated in the drawing and operated by a user's manipulation, or may be implemented as an electromagnetic valve and operated by external control. In the latter case, a supervisor who detects a fire can control the supply of fire extinguishing water from a remote location by operating an electronic valve in a system connected to a communication network.

The fire water distribution pipe 200 is connected to two or more fire hoses, and sequentially delivers fire water supplied from the fire water supply line 20 to the two or more fire hoses. In the examples of Figures 1 to 3, the fire water distribution pipe 200 is a hose reel 11, which is a fire hose with a relatively small diameter and short hose length wound on a reel, and a hose reel 11 with a relatively large diameter and long hose length. It shows an example connected to a fire hose (12) for supplying a large amount of fire extinguishing water at high pressure and a filter unit (13) that purifies the fire extinguishing water so that it can be consumed.

For this purpose, the fire water distribution pipe 200 may be composed of a distribution cylinder 210 and a distribution piston 220.

The distribution cylinder 210 has one side connected to the fire water supply line 20 and the other side in contact with the inner surface of the fire hydrant 10, and two or more branch openings for supplying fire water to two or more fire hoses are formed in the body. In the examples of FIGS. 1 to 3, first to third branch openings 211 to 213 are formed to supply fire extinguishing water to the hose reel 11, fire hose 12, and filter unit 13, respectively. An example is shown.

The distribution piston 220 closes the branch port (e.g., the first to third branch ports 211 to 213) when there is no fire extinguishing water, that is, when the fire extinguishing water does not flow in, and distributes by the inflow of the fire extinguishing water. The branch openings (eg, first to third branch openings 211 to 213) are sequentially opened while sliding the inner surface of the cylinder 210. At this time, the other side of the distribution piston 220 may protrude to the outside through the protrusion 14 formed in the fire hydrant 10. For this purpose, when fire extinguishing water is not flowing in, the protrusion 14 is closed with a soft membrane or stopper 15, and then the membrane is broken by the movement of the distribution piston 220, thereby opening the other side of the distribution piston 220. It can be extruded. The movement of the distribution piston 220, the sequential opening of the branch port accordingly, and the operations related to the protrusion of the other side of the distribution piston 220 are illustrated in Figures 4 to 8, see Figures 4 to 8. This will be described later.

In addition, the distribution piston 220 includes a sliding disk 221 that moves along the inner surface of the distribution cylinder 210, a throwing fire extinguishing member 222 that is detachable after being filled with fire extinguishing water, and a throwing fire extinguishing member 222. It may be configured to include a supporting member 223. At this time, the support member 223 can prevent the throwing fire extinguishing member 222 from sagging downward when the distribution piston 220 protrudes out of the fire hydrant 10. In particular, when the throw fire extinguishing member 222 includes a plurality of throw fire extinguishers, the connection can be maintained without being released. In addition, the support member 223 is formed as a plate structure in contact with the inner surface of the distribution cylinder 210, and can close the branch openings (e.g., the first to third branch openings 211 to 213). .

The sliding disk 221 pushes the throwing fire extinguishing member 222 to protrude outside the hydrant by the water pressure of the fire extinguishing water flowing into the distribution cylinder 210 in a state where the fire extinguishing water is buffered in the throwing fire extinguishing member 222. The outer peripheral surface moves along the inner surface of the distribution cylinder (210). For this purpose, the sliding disk 221 has an insertion hole 221-2 formed in the center so that the inlet holes 222a-3 and 222b-3 protruding from the throwing fire extinguishing member 222 are inserted to introduce the fire extinguishing water. , a discharge stopper (221-1) that blocks the insertion hole (221-2) to prevent fire extinguishing water from leaking out when the throwing fire extinguishing member (222) is separated, and a sliding disk (221) to prevent leakage of fire extinguishing water. ) It includes a sliding seal that makes airtight contact between the outer peripheral surface and the inner surface of the distribution cylinder 210.

The throwing fire extinguishing member 222 is provided with a hollow throwing fire extinguisher (222a or 222b) filled with fire extinguishing water, and the throwing fire extinguisher (222a or 222b) is formed protruding on one side and has an inlet hole (222a) through which fire extinguishing water flows. -3 or 222b-3) and an inlet stopper (222a-2 or 222b-2) that closes the inlet hole (222a-3 or 222b-3) in the absence of fire extinguishing water and opens when fire extinguishing water flows in.

On the other hand, a plurality of throwing fire extinguishers (222a or 222b) may be arranged in a row so that the inlet hole (222a-3 or 222b-3) is facing the fire extinguishing water supply line 20 and can be separated and coupled to the distribution cylinder (210). ), except for one throwing fire extinguisher (222b) located on the other side and in contact with the inner surface of the fire hydrant (10), the remaining throwing fire extinguishers (222a) are discharged to discharge fire water to another throwing fire extinguisher connected to the rear. ball (222a-4); And it may further include a discharge stopper (222a-1) that closes the discharge hole (222a-4) and opens when another throwing fire extinguisher is coupled to the rear.

1 to 3 illustrate a throwable fire extinguishing member 222 including four throwable fire extinguishers, and three of the four throwable fire extinguishers have an inlet hole (222a-3) and an inlet stopper. (222a-2), a discharge hole (222a-4), and a discharge stopper (222a-1). It is a throwing fire extinguisher (222b) equipped only with (222b-2).

3A and B are enlarged views to explain the combined structure of these throwing fire extinguishers (222a, 222b). A in FIG. 3 shows the throwing fire extinguisher (222a) and the sliding disk 221 located at the forefront. As a coupling relationship, the inlet hole (222a-3) of the throwing fire extinguisher (222a) located at the forefront is inserted into the insertion hole (221-2) formed in the sliding disk 221, and as a result, the discharge stopper (221-1) ) illustrates an open state, and B in FIG. 3 is a coupling relationship between the last throwing fire extinguisher (222b) and the throwing fire extinguisher (222a) located at the front, and the last throwing fire extinguisher (222b) The inlet hole (222b-3) of is inserted into the discharge hole (222a-4) of the throwing fire extinguisher (222a) located at the front end, and as a result, the discharge plug (222a-1) is opened. Meanwhile, in the above example, the inlet plugs (222a-2, 222b-2) of each of the throwing fire extinguishers (222a, 222b) close the corresponding inlet holes (222a-3, 222b-3), respectively, and the inlet plugs (222a-2, 222b-2) is opened by the water pressure when fire extinguishing water flows in, forming an inflow path for the extinguishing water.

In the examples of FIGS. 1 to 3, the case where the throwing fire extinguishing member 222 is composed of four throwing fire extinguishers (222a and 222b) is illustrated, but the number of throwing fire extinguishers is determined by the length and distribution of the throwing fire extinguishers. It may be applied differently depending on the length of the cylinder 210. At this time, the last stop-type throwing fire extinguisher (222b) must include one, and the number of connected throw-type fire extinguishers (222a) having a connection structure can be changed.

Meanwhile, in the above example, the discharge stopper 221-1 that determines the opening/closing of the insertion hole 221-2 formed in the sliding disk 221, the inlet hole 222a of each of the throwing fire extinguishers (222a, 222b) -3, 222b-3) inlet plugs (222a-2, 222b-2) that determine the opening and closing, and discharge plugs that determine the opening and closing of the discharge hole (222a-4) of each of the throwing fire extinguishers (222a) (222a-1) each applies a force in the direction of closing the corresponding hole (i.e., the insertion hole (221-2), the inlet hole (222a-3, 222b-3), and the discharge hole (222a-4). It can be implemented as a torsion spring.

Figure 4 is a perspective view of a fire hydrant showing a state in which the throwing fire extinguishing member included in the fire water distributor for fire hydrant according to an embodiment of the present invention is protruding, and Figures 5 and 6 are a fire extinguishing device according to an embodiment of the present invention. These are cross-sectional views to explain the operation when fire extinguishing water flows into the water distributor. In particular, Figures C and D of Figures 5 are enlarged views illustrating the movement path of fire extinguishing water (W), and Figure 5C shows that the inlet hole 222a-3 of the throwing fire extinguisher 222a is a sliding disk 221. Example of a state in which the discharge plug (221-1) is opened by being inserted into the insertion hole (221-2) of the fire extinguisher (222a) and the inlet hole (222a-3) is closed by the inlet plug (222a-2) of the throwing fire extinguisher (222a). 5D illustrates a state in which the inlet stopper 222a-2 of the throwing fire extinguisher 222a opens the inlet hole 222a-3 due to the continuous inflow of fire extinguishing water (W). Therefore, C in Figure 5 shows the state before the fire extinguishing water (W) flows into the throwing fire extinguisher (222a), and D in Figure 5 shows the state before the fire extinguishing water (W) flows into the throwing fire extinguisher (222a). indicates.

By repeating this process, as illustrated in FIG. 5, fire extinguishing water (W) can be introduced into all the throwing fire extinguishers (222a, 222b) constituting the distribution piston 220.

On the other hand, when the extinguishing water (W) is continuously flowing in while the extinguishing water (W) is fully charged inside all the throwing fire extinguishers (222a, 222b), as illustrated in FIG. 6, the distribution piston 220 The throwing fire extinguisher (222b) coupled to the end may sequentially protrude out of the fire hydrant (10). In this process, the distribution piston 220 may sequentially open branch openings (eg, first to third branch openings 211 to 213) formed in the distribution cylinder 210.

Figure 6 (a) illustrates a state in which the first branch port 211 is opened while one throwing fire extinguisher (222b) protrudes to the outside, and Figure 6 (b) shows all the fire extinguishers mounted on the distribution piston 220. This illustrates a state in which the throwing fire extinguishers (222a, 222b) protrude to the outside and all of the first to third branch openings (211 to 213) are open. In particular, Figure 6 (a) shows an example in which one throwing fire extinguisher (222b) protrudes to the outside, and the stopper (15) that closed the protruding hole (14) of the fire hydrant (10) is separated (or destroyed). .

Figures 7 and 8 are views for explaining a state in which a portion of a throwing fire extinguishing member protruding outside a fire hydrant is separated according to an embodiment of the present invention. Referring to FIGS. 1 to 8, the plurality of throwing fire extinguishers (222a, 222b) protruding outside of the fire hydrant 10 can be separated by external force. In this case, the throwing fire extinguisher (222a) is formed on the other side. The discharge hole 222a-4 is closed by the restoring force of the torsion spring constituting the discharge stopper 222a-1.

In particular, E in FIG. 8 shows a state in which the throwing fire extinguishers 222a and 222b are combined, and F in FIG. 8 shows a state in which the throwing fire extinguisher 222b is separated. Referring to FIGS. E and F of FIG. 8, in a state where the throwing fire extinguishers (222a, 222b) buffered with fire extinguishing water are combined, the opening and closing of each discharge hole (222a-4) and inlet hole (222b-3) is determined. With all the plugs (discharge plug 222a-1 and inlet plug 222b-2) open and the throwing fire extinguishers (222a, 222b) separated, each discharge hole (222a-4) and It can be seen that all of the plugs (discharge plug 222a-1 and inlet plug 222b-2) that determine the opening and closing of the inlet hole 222b-3 are closed.

This is to prevent fire extinguishing water from leaking to the outside due to separation of the throwing fire extinguisher.

Meanwhile, the throwing fire extinguishers (222a, 222b) are each coupled by a screw fastening or fitting structure, and can be easily separated by being uncoupled by a rotational or pulling force applied from the outside.

The present invention makes it possible to easily extinguish an initial fire by throwing the detachable throwing fire extinguisher at the point where the fire occurs.

In this way, the present invention distributes the fire extinguishing water supplied through the fire water supply line to a hollow throwing fire extinguisher and then protrudes the buffered throwing fire extinguisher outside the fire hydrant, making it easy to extinguish fire without handling a heavy hose reel or fire hose.
