Description

Fire fighting equipment using water {FIRE FIGHTING EQUIPMENTS USING WATERWORKS}

The present invention relates to a fire-fighting apparatus using water, and in particular, a domestic water pipe with low water pressure and low water quantity as a water supply source to sufficiently increase the water pressure and supply it to the injector so that fire suppression is achieved, and the structure is simplified and miniaturized. The present invention relates to a fire-fighting apparatus using water, which can be easily used in a general home by being automatically made.

In general, small automatic fire extinguishers are provided in the home to make up for the shortcomings of large fire extinguishing equipment that are not capable of responding directly to the fire.

This automatic fire extinguisher has a function of blocking the gas supply of the gas range, and a function of injecting a fire extinguishing agent, and all operations are automatically performed by a sensor.

When the automatic fire extinguisher occurs in the gas range, the fire extinguishing agent is automatically sprayed by the detection of the sensor to extinguish the fire and block the gas supplied to the gas range to prevent a large fire.

However, since the automatic fire extinguisher has a small amount of fire extinguishing agent, it only plays a role of suppressing a small fire generated in a gas range, so it is difficult to expect a complete fire extinguishing, and in particular, the ability to respond to a large fire is difficult. There is a disadvantage. In addition, the extinguishing agent also has a problem of corroding the metal of the gas range after the digestion as a reinforcing liquid.

On the other hand, a large fire fighting system with a sprinkler system for extinguishing a large fire of a building is known.

Since the fire fighting system requires a large amount of water and high water pressure, water is stored in a water tank installed on the roof or basement by a pump or sprayed by a sprinkler installed inside the building by receiving water from a tank of a fire truck. To lose. Such fire fighting systems must supply water with high pressure so that the sprinkler can spray water with sufficient spray pressure through a number of distribution pipes installed inside the building.

The fire fighting system has the advantage of being able to extinguish a large-scale fire initially because the injection of water is made through a plurality of sprinklers.

However, such a fire fighting system is expensive and expensive to operate, and is mainly installed in a common house such as a mall, an office building, an apartment, and the like.

In addition, the firefighting system is a place where the supply line for supplying water depending on the installation is installed outside the building, the water inside the supply line may freeze in the winter of low temperature, and the supply line is freezing in severe cases Occurs. In this case, the water is not supplied to the sprinkler has a problem that does not function when a large fire occurs.

The present invention has been made in order to solve the above problems, an object of the present invention is to provide a fire suppression by supplying to the injector by raising the water pressure sufficiently by using a water supply with low water pressure and low water quantity as a water supply source, structure By simplifying the miniaturization and automatic operation, it is intended to be easily used in general homes such as detached houses.

The pumping apparatus 100 includes a first supply pipe 112 and a second supply pipe 116 branched to both sides from an inlet 110 connected to the water pipe 900, and one end of the first supply pipe 112 and the second supply pipe 112. The first discharge pipe 130 and the second discharge pipe 134 connected to the supply pipe 116 and the other end connected to the outlet 140 connected to the distribution pipe 200, the first supply pipe 112 and the first discharge pipe 130, respectively ) To the side of the second pumping passage 122 connecting the first cylinder 150 and the second supply pipe 116 and the second discharge pipe 134 communicating with the side of the first pumping passage 120 connecting The second cylinder 152 communicated with the first supply pipe 112 is installed in the interior of the first supply pipe 112 to allow the flow of water moving from the first cylinder 150 side and the first cylinder 150 from the first The first check valve 114 to block the flow of water to the first supply pipe 112 and the second supply pipe 116 is installed inside the second supply pipe 116 to move to the second cylinder 152 side A second check valve 118 for allowing the flow of water and blocking the flow of water moving from the second cylinder 152 to the second supply pipe 116, and the first cylinder (130) installed inside the first discharge pipe (130) The third check valve 132 and the second discharge pipe to allow the flow of water from the 150 to the first discharge pipe 130 side and block the flow of water moving from the first discharge pipe 130 to the second cylinder 152 Is installed inside the 134 to allow the flow of water from the second cylinder 152 to the second discharge pipe 134 and to block the flow of water moving from the second discharge pipe 134 to the second cylinder 152 The first supply pipe 112 is mounted in communication with the fourth check valve 136, the first cylinder 150, and the second cylinder 152 through the first pumping passage 120 under the control of the computer 600. Intake of the water inside and discharged to the first discharge pipe 130 side in the second supply pipe 116 through the second pumping passage 122 To intersect the operation for discharging toward the second discharge pipe 134 by suction of water takes place as part of pumped carried out continuously.

The pumping unit may open and close the first piston 160 to open and close the first pumping passage 120 in the first cylinder 150, and the second pumping passage 122 to the inside of the second cylinder 152. A housing 170 installed in communication with the first cylinder 150 and the second cylinder 152 between the second piston 164, the first piston 160, and the second piston 164, and the housing 170. Screw shaft 168 connecting the center of the first piston 160 and the second piston 164 through the () and the housing 170 is installed in the housing 170 to control the forward and reverse rotation by the control of the computer 600 A repetitive motor 172, a gear reduction gear group 174 installed in the housing 170 to transfer the screw shaft 168 by the rotational force of the motor 172, the first piston 160 and the second piston 164. And a first limit switch 162 and a second limit switch 166 which are respectively installed at the first piston 160 and the second piston 164 to detect a transfer completion operation of the first piston 160 and the second piston 164 and transmit the same to the computer 600. Lose.

A through hole 171 through which the screw shaft 168 passes is formed in the housing 170, and a protrusion 171-1 is formed on an inner circumferential surface of the through hole 171. The guide groove 169 to which the protrusion 171-1 is coupled is formed in the longitudinal direction on the outer circumferential surface of the screw shaft 168. The protrusion 171-1 and the guide groove 169 are for preventing the screw shaft 168 from rotating when the reduction gear group 174 rotates and the screw shaft 168 is elevated.

In the reduction gear group 174, a screw groove 176 in which the screw shaft 168 is screwed is formed at the center of the gear connected to the screw shaft 168. Therefore, the rotational force of the reduction gear group 174 is transmitted to the screw shaft 168.

Since water having a constant pressure is stored in the water pipe 900, the first check valve 114, the second check valve 118, the third check valve 132, and the fourth check valve 136 may have water. It is to have a spring elastic force that does not open at the pressure in the pipe (900).

And since the pressure air is always stored in the distribution pipe 200, the pressure sensor 400 to have a spring elastic force that is not operated at the pressure in the distribution pipe (200).

When the number of the pumping device 100 is large, it is possible to supply water having sufficient pressure even when installed in a large building in which a large number of injectors 300 or 500 are installed. In addition, as the number of the pumping device 100 increases, the pulsation phenomenon due to the reciprocating motion of the pumping part may be removed, thereby allowing continuous water supply.

On the other hand, the injector (300 or 500) uses a sprinkler of the type that is opened by the heat in the event of a fire, and is fixed to the ceiling of each room in need of fire suppression in the building.

Some of these injectors (300 or 500) uses a small injector 300, such as a microwave oven is arranged in a location where a high amount of water injection is required while a high rate of fire. The small injector 300 is a plug 312 made of lead is coupled to the outlet 310 formed at the end of the distribution pipe 200, the stopper 312 is weakened in the hardness of the surface by the heat of the high temperature in the event of a fire And is discharged from the discharge port 310 by the pressure of the air filled in the distribution pipe 200.

And a pressure gauge 250 is installed in the distribution pipe 200. This pressure gauge is to know the pressure of the air filled in the distribution pipe (200).

On the other hand, the gas circuit breaker 700 for blocking the gas supply line wired inside the building is connected to the computer 600. And the computer 600 is connected to the gas detector 800 for detecting the leakage of gas.

Hereinafter, the operation of the fire fighting device having the configuration as described above.

When initially setting the fire fighting system of the present embodiment, the pumping device 100 is temporarily operated before connecting the water supply pipe 900 to compress air in the distribution pipe 200. At this time, while watching the pressure gauge 250 to charge the air at the set pressure. The pressure gauge 250 allows the user to know the pressure of the air in the distribution pipe 200 even in normal times.

Subsequently, the inlet 110 of the pumping apparatus 100 is connected to the water pipe 900, and the first supply pipe 112 and the second supply pipe 116 are opened through the inlet 110 connected to the water pipe 900 by opening the water. ) Tap water. The tap water passes through the first check valve 114 and the second check valve 118 when the pumping device 100 is operated, and thus, the first cylinder 150 through the first pumping passage 120 and the second pumping passage 122. ) And the second cylinder 152.

The pumping action of the pumping device 100 will be described in detail below.

Normally, the gas detector 800 connected to the computer 600 detects the gas leaking into the room.

If the gas is detected in the gas detector 800, the computer 600 controls the gas circuit breaker 700 to close the gas line in the room so that no further gas leakage occurs.

On the other hand, when a fire occurs in the gas stove, the plug 312 inserted into the outlet 310 coupled to the end of the distribution pipe 200, the hardness of the surface is weakened by the heat of high temperature is filled in the distribution pipe 200 The air is released from the outlet 310 by the pressure. Therefore, the pressure of the air in the distribution pipe 200 drops rapidly. In addition, even when a fire occurs indoors, the pressure of the air in the distribution pipe 200 rapidly drops while the injector 300 or 500 is opened by heat.

At this time, the pressure sensor 400 detects the pressure drop in the distribution pipe 200 and transfers this information to the computer 600. The computer 600 determines that a fire has occurred based on the information of the pressure sensor 400, and operates the pumping apparatus 100 to extinguish the fire. At the same time, by operating the gas circuit breaker 700 to block the gas supplied to the room, to prevent the gas leaks into the flame and spread to a large fire.

On the other hand, the motor 172 of the pumping device 100 is rotated by applying the power of the computer 600 to rotate the reduction gear group 174 to transfer the screw shaft 168 in one direction. At this time, the protrusion 171-1 of the housing 170 is coupled to the guide groove 169 of the screw shaft 168 to prevent rotation of the screw shaft 168. If the screw shaft 168 rotates together with the rotation of the reduction gear group 174, the first piston 160 and the second piston 164 rotate together to lift and lower the screw shaft 168 and the first piston 160. ) And the second piston 164 is no movement phenomenon.

When the first piston 160 moves to the first pumping passage 120 by the screw shaft 168, the first check valve 114 blocks the first supply pipe 112, so that the first supply pipe ( Water does not move to the side 112, and since the third check valve 132 opens the first discharge pipe 130 by the pressure of the water, the water moves to the first discharge pipe 130 and the distribution pipe through the outlet 140. It is moved to (200).

At the same time, since the second piston 164 is far from the second pumping passage 122, a vacuum pressure is generated in the second cylinder 152. Accordingly, the water of the second supply pipe 116 passes through the second check valve 118 and is filled into the second cylinder 152 via the second pumping passage 122. At this time, since the fourth check valve 136 is blocking the second discharge pipe 134, the water in the second discharge pipe 134 does not move into the second cylinder 152.

As such, when the first piston 160 is completely moved toward the first pumping passage 120, the second limit switch 166 installed in the second piston 164 is turned on, thereby stopping the motor 172. The screw shaft 168 is moved in the reverse direction by preventing the overload and rotating the motor 172 in the reverse direction in the computer 600.

As a result, the first piston 160 moves away from the first pumping passage 120 to generate vacuum pressure in the first cylinder 150, and the first check valve 114 opens the first supply pipe 112. The tap water is introduced into the first cylinder 150 through the first supply pipe 112. In addition, since the third check valve 132 blocks the first discharge pipe 130, the water in the first discharge pipe 130 does not move toward the first cylinder 150.

At the same time, when the second piston 164 moves to the second pumping passage 122 by the transfer of the screw shaft 168, the fourth check valve 136 opens the second discharge pipe 134 by the pressure of water. Therefore, the water moves to the second discharge pipe 134 is moved to the distribution pipe 200 through the outlet 140. In addition, since the second check valve 118 blocks the second supply pipe 116, water does not move to the second supply pipe 116.

As such, when the second piston 164 is completely moved toward the second pumping passage 122, the first limit switch 162 installed in the first piston 160 is turned on, and thus the motor 172 is stopped. It prevents overload and rotates the motor 172 in the reverse direction in the computer 600 to move the screw in the reverse direction.

In this way, water is continuously supplied to the outlet 140 and moved to the corresponding injector 300 or 500 through each distribution pipe 200. While the tap water passes through the pumping device 100, the water pressure is enhanced to have sufficient pressure to inject water from the injector 300 or 500.

The water moved to the injector (300 or 500) is evenly sprayed in the place where the fire occurs to extinguish the fire.

On the other hand, since the distribution pipe 200 in which water moves is normally filled with only pressure air, the distribution pipe 200 does not freeze in winter.

As described above, the present invention is provided in the pumping device 100 and the distribution pipe 200 for continuously supplying water to the distribution pipe 200 piped in a position requiring waterproofing inside the building by receiving tap water. Pressure sensor 400 for detecting the pressure drop of the distribution pipe 200, the injector (300 or 500) connected to the end of the distribution pipe 200 for spraying water, and the pressure drop information of the pressure sensor 400 Receiving the pumping device 100 to operate the computer 600; Fire-fighting device using a water, including a simple structure, the volume is small and automatically operated, so that the effect can be easily used in general homes, such as single-family homes have. In addition, the fire-fighting device of the present invention, so that the water pressure in the injector (300 or 500) is made to enhance the water pressure in the pumping device 100 even with a low water pressure and low water supply home water pipe (900) as a water supply source It can be used not only in general households but also in places where extinguishing large fires. In addition, since the distribution pipe 200 in which water moves is normally filled with only pressure air, freezing of the distribution pipe 200 is prevented in the winter.
