Description

  The present invention relates to a sprinkler fire extinguishing equipment using a chemical solution as a fire extinguishing agent.

  Conventionally, there are sprinkler fire extinguishing equipment that uses tap water as a fire extinguishing agent. In this sprinkler fire extinguishing equipment, tap water pressure is used to supply tap water to the sprinkler head. Therefore, in the case of such an installation, a fire extinguishing agent tank and a pump are unnecessary.

  Conventionally, there is a sprinkler fire extinguishing facility that uses a chemical solution as a fire extinguisher. In this sprinkler fire extinguishing equipment, a fire extinguisher tank for storing a fire extinguisher is required. Furthermore, a dedicated pump is required to supply the fire extinguisher from the fire extinguisher tank to the sprinkler head.

  As described above, a dedicated pump is required in a sprinkler fire extinguishing facility that uses a chemical solution as a fire extinguisher. However, if the installation location of the pump cannot be secured, the sprinkler fire extinguishing equipment itself cannot be installed, the cost of purchasing and installing the dedicated pump, the maintenance cost for periodic inspection, etc. There was a great burden of.

  The present invention has been made to solve the above problems, and in a sprinkler fire extinguishing equipment that uses a chemical solution as a fire extinguisher, a fire extinguishing agent that is a chemical solution is used without using a dedicated pump. It is to provide a sprinkler fire extinguishing equipment that can be discharged.

Hereinafter, the configuration employed to achieve the above object in the present invention will be described.
The sprinkler fire extinguishing equipment of the present invention includes a first container that contains a fire extinguishing agent therein, a sprinkler head having a discharge port that can discharge the fire extinguishing agent toward a fire extinguishing target, Opening / closing that is in a closed state that prevents the supply of the fire extinguishing agent to the sprinkler head and switches to an open state that does not prevent the supply of the fire extinguishing agent from the first container to the sprinkler head in the event of a fire. The first container has a structure in which pressure is always applied in a direction of crushing the first container from the outside of the first container, and the opening / closing mechanism is in the closed state. Sometimes, even if the first container receives the pressure, the extinguishing agent is not pushed out of the first container, and the first container is maintained in a state where it is not crushed, while the opening / closing mechanism When switched to the open state, the first container is crushed by receiving the pressure, the extinguishing agent from the sprinkler head is characterized in that it is released.

  In the sprinkler fire extinguishing equipment of the present invention, the first container has a structure in which pressure always acts in the direction of crushing the first container from the outside of the first container, and when the opening / closing mechanism is switched to the open state First, the first container is crushed under pressure, and the fire extinguishing agent is released from the sprinkler head.

  With such a sprinkler fire extinguishing equipment, the fire extinguisher contained in the first container can be supplied to the sprinkler head without using a dedicated pump as described above. Therefore, it is possible to provide a sprinkler fire extinguishing facility that can discharge a fire extinguishing agent without using a dedicated pump.

  In addition, since June 1, 2006, all new homes have been required to install residential fire alarms, and existing homes must also be installed by May 31, 2007. However, even if the alarm sounds, a hearing impaired person, a person with a disability, or a bedridden person may be late to escape. In this respect, when the sprinkler fire extinguishing equipment of the present invention is installed, it is possible to protect important lives from fire, and it is also effective for fires and misfires caused by earthquakes.

  Next, the sprinkler fire extinguishing equipment of the present invention includes a second container that is constantly supplied with water from the water source side, and the first container and the second container are independent from each other. In addition, it is preferable that the water pressure in the second container always has a structure that acts in the direction of crushing the first container.

  With such a structure, the fire extinguishing agent accommodated inside the first container and the water supplied to the inside of the second container are in each container wall both at all times and at the time of the occurrence of a fire. Is isolated and never mixed.

  In sprinkler fire extinguishing equipment that uses a chemical solution as a fire extinguisher, it is legally prohibited to directly connect the fire extinguisher supply pipe and the water pipe because the fire extinguisher and tap water may be mixed. Yes. In this respect, in the sprinkler fire extinguishing equipment of the present invention, the fire-extinguishing agent supply pipe and the water pipe are not directly connected, and the water supplied to the inside of the second container and the fire-extinguishing agent are not mixed. Therefore, if the sprinkler fire extinguishing equipment has such a structure, the sprinkler fire extinguishing equipment that uses a chemical solution as a fire extinguishing agent is partially equipped with a system that uses tap water, but there is no legal problem. .

  Next, in the sprinkler fire extinguishing equipment of the present invention, the first container and the second container are arranged side by side inside the third container, and the second container is supplied into the second container. The volume of the second container increases as the amount of water increases, and the volume of the second container increases in a direction that is restricted by the third container and is not in contact with the third container. In addition, it is preferable that a part of the second container that is displaced as the volume increases presses the outer surface of the first container.

  With this structure, the volume of the second container is restricted from increasing in the direction in contact with the third container, and increases in the direction in which the first container is disposed. Therefore, the pressing force can be efficiently transmitted from the second container to the first container as compared with the case where the structure in which the volume increasing direction of the second container is not particularly restricted is employed.

  Next, in the sprinkler fire extinguishing equipment of the present invention, the third container is preferably a protective container that prevents the first container and the second container from being damaged by the impact when the third container receives an impact from the outside. .

  For example, if the third container is made of a metal such as stainless steel, even if a debris of a building falls and an impact is applied to the third container when a fire occurs, the first container is affected by such an impact. The container and the second container can be prevented from being damaged.

Next, in the sprinkler fire extinguishing equipment of the present invention, the second container is preferably connected to a water pipe.
As described above, when a dedicated pump is installed in the sprinkler fire extinguishing equipment, the pump is mainly electric, so if a power failure occurs due to a fire, the pump will not operate and the sprinkler head will extinguish. There is a risk that the agent cannot be supplied.

  In this regard, in the sprinkler fire extinguishing equipment of the present invention, by connecting a water pipe directly to the second container, the water pressure from the water pipe is used to release the fire extinguishing agent, so that the water pressure of the tap water is maintained even during a power failure. As long as possible, the sprinkler fire extinguishing system can be operated properly.

  Next, in the sprinkler fire extinguishing equipment of the present invention, the open / close mechanism includes an open / close valve that switches whether or not water flows from the first container to the sprinkler head, a weight, A weight support member that drops the weight as it receives heat and melts in the event of a fire, and transmits the weight load to the on-off valve when the weight support member drops the weight. It is preferable to provide a load transmission member that switches the on-off valve from the closed state to the open state.

  In the case of this sprinkler fire extinguishing equipment, the weight support member melts due to heat from the fire, the weight falls, and the load of the weight is transmitted, so that the load transmission member switches the on-off valve from the closed state to the open state. When the open / close valve is switched to the open state, the open / close mechanism is switched to the open state, and the fire extinguishing agent is supplied from the first container to the sprinkler head.

  Therefore, even if a mechanism for operating the on / off valve with an electric actuator is not provided, the on / off valve can be operated in the event of a fire. In addition, unlike the case of sealing the outlet of the sprinkler head with a heat-sensitive metal member, each member constituting the opening / closing mechanism can be disposed at a position different from the sprinkler head. Thus, for example, the weights and weight support members are unevenly distributed at positions where the fire hand is likely to rise. The arrangement position of each member can be optimized in consideration of the function of each member, for example, the sprinkler head is arranged in the center of the room.

Next, embodiments of the present invention will be described with specific examples.
[First Embodiment]
Drawing 1 is an explanatory view showing the installation state of the sprinkler fire extinguishing equipment illustrated as one embodiment of the present invention. The sprinkler fire extinguishing equipment 1 includes a water supply pipe 3, a fire extinguisher supply apparatus 10, a fire extinguisher supply pipe 4, and a sprinkler head 5. Among them, the water supply pipe 3, the fire extinguisher supply apparatus 10, and the fire extinguisher supply pipe 4 are installed in the ceiling 8 of the living room inside the building, and the sprinkler head 5 is installed on the ceiling 9 of the living room. Yes.

  The water supply pipe 3 is branched from a water pipe (not shown), and supplies tap water to the fire extinguisher supply device 10 with the water pressure of the water pipe. The fire extinguisher supply device 10 contains a fire extinguisher inside, and supplies the fire extinguisher to the sprinkler head 5 by the action of the water pressure of tap water supplied from the water supply pipe 3.

  The extinguishing agent supply pipe 4 is a pipe for connecting the extinguishing agent supply device 10 and the sprinkler head 5 and supplying the extinguishing agent from the extinguishing agent supply device 10 to the sprinkler head 5. The sprinkler head 5 discharges the extinguishing agent supplied from the extinguishing agent supply device 10 toward the extinguishing target.

In the present embodiment, a so-called closed sprinkler head is used as the sprinkler head 5. Specifically, the sprinkler head 5 has a discharge port for discharging a fire extinguisher, and this discharge port is normally sealed with a metal lid, and hydraulic pressure acts from the fire extinguisher in the sprinkler head 5. Even so, the metal lid is designed to prevent the release of fire extinguishing agent. The metal lid is formed of an alloy that melts when the temperature is 72 ° C. or higher. When the temperature is 72 ° C. or higher due to heat from a fire, the alloy is melted and the discharge port is opened. The sprinkler head 5 can discharge the fire extinguishing agent from the discharge port at a pressure of 1 kg / cm ² or more at a rate of 50 liters per minute or more.

  Moreover, the fire extinguisher is using the aqueous solution which made the commercial item (brand name: Fire Ade 2000, the product made by Fire Service Plus) 0.25%-1.0% concentration. This aqueous solution is in a liquid state at room temperature.

FIG. 2A is a cross-sectional view of the fire extinguisher supply device 10. The fire extinguisher supply device 10 includes a water tank 12, a fire extinguisher tank 13, and an outer container 15.
The water tank 12 is a container of elastic rubber having elasticity, and has a structure in which the volume increases as the amount of supplied tap water increases. The water tank 12 is directly connected to the open end of the water supply pipe 3, and the tap water is always supplied via the water supply pipe 3 due to the water pressure from the water pipe.

  The fire extinguisher tank 13 is a container made of synthetic rubber and has a structure that is crushed when a predetermined pressure is applied. The extinguishing agent tank 13 is directly connected to the opening end of the extinguishing agent supply pipe 4 and has a structure for supplying the extinguishing agent to the sprinkler head 5 via the extinguishing agent supply pipe 4.

  The water tank 12 and the fire extinguishing agent tank 13 are arranged side by side in the outer container 15 and are in contact with the inner wall of the outer container 15. Furthermore, since the outer container 15 is a stainless steel container, even if debris falls and an impact is applied to the fire extinguisher supply device 10 in the event of a fire, the water tank 12 and the fire extinguishing agent contained by such an impact are applied. It is possible to prevent the tank 13 from being damaged.

Next, the operation of the fire extinguisher supply device 10 at all times and when a fire occurs will be described with reference to FIGS. 2 (a) and 2 (b).
First, FIG. 2A is a cross-sectional view showing a state of the fire extinguisher supply device 10 at a normal time. Since the discharge port of the sprinkler head 5 is normally sealed with an alloy as described above, the fire extinguishing agent is not discharged. Therefore, the extinguishing agent is accommodated inside the extinguishing agent tank 13, the extinguishing agent supply pipe 4, and the sprinkler head 5. In the water tank 12, tap water is always supplied from the water supply pipe 3.

  Here, since the water tank 12 is a container having a structure in which the volume is increased, the object is pushed by the outer wall of the water tank 12 that becomes larger. Thereby, the water pressure of the tap water in the water tank 12 acts on the object. That is, the water pressure in the water tank 12 acts on the extinguishant tank 13 and the outer container 15 that are objects to be in contact with the outer wall of the water tank 12. Since the outer wall of the water tank 12 is always in contact with the extinguishant tank 13 and the outer container 15 at all times, the water pressure always acts on the extinguishant tank 13 and the outer container 15.

  Next, FIG.2 (b) is sectional drawing which showed the state of the extinguishing agent supply apparatus 10 at the time of fire outbreak. When a fire occurs, as described above, the metal sealing the discharge port of the sprinkler head 5 melts, the discharge port opens, and the fire extinguishing agent starts to be released.

  In the water tank 12, since tap water is always supplied, the amount of water inside increases and the volume increases. In the fire extinguisher tank 13, the water pressure in the water tank 12 acts as described above, and the fire extinguisher tank 13 is crushed by the outer wall of the water tank 12. As described above, the fire extinguisher is supplied to the sprinkler head 5 through the fire extinguisher supply pipe 4 and discharged from the discharge port.

  Here, as described above, the water pressure in the water tank 12 is constantly acting on the fire extinguisher tank 13 and the outer container 15. Since the outer container 15 is a stainless steel container, the volume of the water tank 12 is regulated without substantially increasing in the direction in contact with the outer container 15. Therefore, the volume of the water tank 12 increases in a direction in contact with the extinguishing agent tank 13, which is a direction not in contact with the outer container 15. Therefore, compared with the case where the direction in which the volume of the container of the water tank 12 increases is not particularly restricted, in the fire extinguisher supply device 10, the water pressure in the water tank 12 acts more efficiently in the direction of crushing the fire extinguisher tank 13. can do.

  With the above configuration, the sprinkler fire extinguishing equipment 1 according to the present embodiment can supply the fire extinguishing agent to the sprinkler head 5 using the water pressure of tap water, and thus can discharge the fire extinguishing agent without using a dedicated pump. It is.

  Moreover, in the sprinkler fire extinguishing equipment 1 of this embodiment, since the water tank 12 and the fire extinguisher tank 13 are independent containers, the fire extinguisher accommodated in the tap water supplied to the water tank 12 and the fire extinguisher tank 13 is used. The drug is not mixed. Further, the water pipe is not directly connected to the fire extinguisher tank 13 and the fire extinguisher supply pipe 4. Therefore, as described above, in the sprinkler fire extinguishing equipment 1 using a chemical solution as a fire extinguishing agent, there is no legal problem even if tap water is used in the water tank 12.

  Furthermore, in the sprinkler fire extinguishing equipment 1 of the present embodiment, the water pressure of the water pipe is used for discharging the fire extinguishing agent. Therefore, as described above, the sprinkler fire extinguishing equipment 1 can operate properly even during a power outage due to a fire. it can.

  The on-off valve 61 is provided between the fire extinguisher supply pipe 4 and the sprinkler head 65, and switches between a valve open state in which the fire extinguisher passes through the sprinkler head and a valve closed state that prevents water flow. Can do.

  The cover 62 is made of stainless steel, and is provided so as to cover the sprinkler head 65 from the outside in order to prevent the extinguishing agent from being discharged from the sprinkler head 65. The fixed metal 63 is made of an alloy that melts at 72 ° C. or higher, and fixes the cover 62 so as not to fall on the ceiling 9.

  The lever 67 is connected to the on-off valve 61. When the predetermined load is applied and the lever 67 is inclined downward from the horizontal state, the on-off valve 61 is switched from the closed state to the open state, and the downwardly inclined state is maintained. While the operation is being performed, the valve opening state is maintained. The connecting chain 69 is a stainless steel chain, and is provided so as to penetrate the ceiling 9 and connect the lever 67 in the ceiling back 8 and the cover 62 in the living room.

Next, the operation of the opening / closing mechanism 60 at all times and when a fire occurs will be described.
