First Embodiment
(Configuration of sprinkler equipment)
The structure of the sprinkler installation which concerns on the 1st Embodiment of this invention is demonstrated, referring FIGS. 1-4.

  FIG. 1 is a schematic view for explaining a schematic configuration of the sprinkler facility 1 according to the first embodiment. The sprinkler facility 1 has a smoke exhausting function for sucking and discharging the smoke of each section, in addition to a fire extinguishing function for sprinkling fire extinguishing water to each of a plurality of sections (for example, rooms) of the building. The building in which the sprinkler facility 1 is provided is, for example, a house, a group home, a building or the like. Although only two sections A and B are shown in FIG. 1 for convenience of explanation, a building actually includes three or more sections.

Below, the structure of the sprinkler installation 1 for implement | achieving the fire-extinguishing function with respect to two divisions A and B shown in FIG. 1, and a smoke exhausting function is demonstrated.
As shown in FIG. 1, the sprinkler facility 1 includes the head units 10A and 10B, the sensors 20A and 20B, the common flow channels 30A and 30B, the extinguishing water flow channels 31A and 31B, and the smoke flow channels 32A and 32B, A first on-off valve 40A, 40B, a second on-off valve 45A, 45B, a water source 50, a smoke exhaust unit 60, and a control unit 80 are provided.

  The head units 10A and 10B are sprinkler heads installed on the ceilings of the sections A and B. Here, as shown in FIG. 1, one head is provided in one section. The heads 10A and 10B have both the function of sprinkling extinguishing water into the compartment and the function of sucking smoke from the compartment. For example, the head unit 10A sprays extinguishing water to the compartment A or sucks smoke from the compartment A. The head portions 10A and 10B are attached at positions where water can be sprayed evenly throughout the sections A and B. Since the configurations of the head units 10A and 10B are the same, the configuration of the head unit 10A will be described below with reference to FIG.

  FIG. 2 is a schematic view for explaining the configuration of the head unit 10A. The head unit 10A is a so-called open head. For this reason, the open mouth which sprinkles the fire extinguishing water of head section 10A is always open unlike a closed head. The head portion 10A has a frame 12 attached to the ceiling side of the section A, and a deflector 13 for sprinkling extinguishing water to the entire section A. Here, the head unit 10A sprays extinguishing water downward, but is not limited thereto. For example, the head unit 10A may spray water upward. In addition, although the head unit 10A sucks smoke in the compartment A (for example, smoke generated at the time of a fire), specifically, the smoke is sucked from an open port for sprinkling fire extinguishing water.

  The sensors 20A and 20B are installed on the ceilings of the sections A and B, and detect fires occurring in the sections A and B. When the sensors 20A and 20B detect a fire, they transmit a fire signal to the control unit 80. Here, the sensors 20A and 20B also have a function as a concentration detection unit that detects the concentration of smoke in the compartment.

  The common flow channels 30A and 30B are pipelines whose one end side is connected to the heads 10A and 10B. The common flow channels 30A, 30B are piped inside the wall of the building. The common flow channels 30A and 30B are dual-purpose flow channels which select and flow either fire extinguishing water or smoke. For example, when the section A is extinguished, extinguishing water sprayed from the head section 10A flows through the common flow path 30A, and when the section A is exhausted, smoke sucked from the head section 10A flows through the common flow path 30A. Similarly, when the section B is extinguished, extinguished water sprayed from the head portion 10B flows through the common flow path 30B, and when the section B is exhausted, smoke sucked from the head portion 10B flows through the common flow path 30B.

  The extinguishing water flow channels 31A, 31B are connected to the other end sides of the common flow channels 30A, 30B, and are first branch flow channels through which the extinguishing water flows from the water source 50. For example, when the section A is extinguished, the extinguished water of the water source 50 flows through the extinguishing water channel 31A and the common channel 30A and is sprayed from the head 10A. Similarly, when the section B is extinguished, the extinguishing water of the water source 50 flows through the extinguishing water channel 31B and the common channel 30B and is sprayed from the head 10B. The fire extinguishing water channels 31A, 31B are, for example, piped inside a wall of a building.

  The smoke flow channels 32A and 32B are second branch flow channels connected to the other end sides of the common flow channels 30A and 30B and through which smoke flows to the smoke exhaust unit 60. For example, when smoke is exhausted from the compartment A, the smoke sucked from the head unit 10A flows through the common flow passage 30A and the smoke flow passage 32A toward the smoke exhausting unit 60. Similarly, at the time of smoke emission in section B, the smoke sucked from the head unit 10B flows through the common flow channel 30B and the smoke flow channel 32B toward the smoke exhaust unit 60. The smoke channels 32A, 32B are, for example, piped inside a wall of a building.

  The first on-off valves 40A and 40B are provided on the extinguishing water flow paths 31A and 31B so as to be able to open and close. The first on-off valves 40A and 40B are controlled to be opened and closed by the control unit 80 and are normally closed, but open when the sections A and B are extinguished. For example, when extinguishing the compartment A, the first on-off valve 40A is opened (the first on-off valve 40B is closed), and the extinguished water of the water source 50 flows toward the head unit 10A. Similarly, when extinguishing the compartment B, the first on-off valve 40B is opened (the first on-off valve 40A is closed), and the extinguished water of the water source 50 flows toward the head portion 10B.

  The second on-off valves 45A, 45B are provided to the smoke flow paths 32A, 32B so as to be able to open and close. The second on-off valves 45A and 45B are controlled to be opened and closed by the control unit 80, and are normally closed, but open at the time of exhausting the sections A and B. For example, at the time of smoke exhaust of section A, the second suction valve 45A is opened (the second lock valve 45B is closed), and the smoke sucked from the head unit 10A flows to the smoke exhaust unit 60. Similarly, at the time of smoke emission in the section B, the second suction valve 45B is opened (the second suction valve 45A is closed), whereby the smoke sucked from the head unit 10B flows to the smoke exhaust unit 60.

  In the present embodiment, the first on-off valve 40A, 40B and the second on-off valve 45A, 45B are the flow of extinguishing water from the extinguishing water flow channels 31A, 31B to the common flow channels 30A, 30B, and from the common flow channels 30A, 30B. It functions as a valve that switches the flow of smoke to the smoke flow paths 32A, 32B. Thereby, depending on the conditions of the sections A and B, either the fire extinguishing water or the smoke can be selected and flowed to the common flow paths 30A and 30B.

  The water source 50 is a source of extinguishing water to the head units 10A and 10B. The water source 50 is provided with, for example, a pump (pressure feed pump) for pumping the extinguishing water. The extinguishing water of the water source 50 is sent to the head portions 10A and 10B and sprinkled by operating the pressure pump at the time of extinguishing the sections A and B.

  The smoke exhaust unit 60 is a facility for discharging the smoke sucked by the head units 10A and 10B to the outside. The smoke exhaust unit 60 is provided with a pump (vacuum pump) for sucking smoke in the sections A and B through the head units 10A and 10B. The smoke in the sections A and B is sucked from the head sections 10A and 10B and sent to the smoke exhaust section 60 and exhausted by the vacuum pump operating at the time of the smoke exhaust in the sections A and B.

  The control unit 80 is a control device that controls the entire sprinkler installation 1. The control unit 80 includes a receiver that receives the fire signal output from the sensors 20A and 20B. The control unit 80 controls the operations of the first on-off valves 40A and 40B, the second on-off valves 45A and 45B, the pressure feed pump of the water source 50, and the vacuum pump of the smoke exhaust unit 60. For example, the control unit 80 controls the opening and closing operations of the first on-off valves 40A and 40B and the second on-off valves 45A and 45B to spray extinguishing water to the head units 10A and 10B or smoke from the head units 10A and 10B. Switch on or off.

  The control unit 80 controls the operation of the first on-off valves 40A and 40B and the second on-off valves 45A and 45B based on the sensing results of the sensors 20A and 20B. For example, when a fire signal is sent from the sensors 20A and 20B, the control unit 80 controls the opening and closing of the first on-off valves 40A and 40B and the second on-off valves 45A and 45B to extinguish fire water to the head units 10A and 10B. To spray water or to suck smoke from the head units 10A and 10B.

  The control unit 80 may control the amount of smoke drawn from the head units 10A and 10B in accordance with the smoke concentration detected by the sensors 20A and 20B, which are concentration detection units. For example, when smoke is generated in the section B, the control unit 80 controls the amount of smoke drawn from the head unit 10B in accordance with the smoke concentration detected by the sensor 20B. Specifically, when the concentration of smoke in the section B is high, the control unit 80 operates the vacuum pump so as to increase the amount of smoke drawn from the head unit 10B. Thereby, the concentration of smoke in section B can be reduced early.

  When the control unit 80 extinguishes one of the adjacent sections A and B, the control section 80 smokes the other section. For example, the control unit 80 causes the head portion 10A of the section A to spray extinguishing water to the section A, and sucks smoke from the section B from the head section 10B of the section B which is an adjacent section adjacent to the section A. Specifically, when a fire in the compartment A is detected by the sensor 20A, the control unit 80 sprays extinguishing water on the head part 10A of the compartment A and sucks smoke from the head part 10B of the compartment B.

  FIG. 3 is a schematic view for explaining the flow of extinguishing water and smoke when extinguishing the section A and exhausting the section B. Here, it is assumed that a fire occurs in the section A and smoke is flowing into the section B. When the sensor 20A detects a fire in the section A, the control unit 80 opens the first on-off valve 40A and opens the second on-off valve 45B. Then, the control unit 80 operates the pumping pump of the water source 50 to pump fire extinguishing water, and operates the vacuum pump of the smoke exhausting unit 60 to suck smoke in the section B. Thereby, as shown by a thick line in FIG. 3, the extinguishing water of the water source 50 flows to the head unit 10A through the extinguishing water channel 31A and the common channel 30A and is sprayed to the section A, and the smoke of the section B is a common channel It flows to the smoke exhaust unit 60 through the flow passage 30B and the smoke flow passage 32B and is discharged.

Similarly, when a fire in the compartment B is detected by the sensor 20B, the control unit 80 sprays extinguishing water on the head part 10B of the compartment B and sucks smoke from the head part 10A of the compartment A.
FIG. 4 is a schematic view for explaining the flow of extinguishing water and smoke when extinguishing the section B and exhausting the section A. When a fire occurs in the section B, the control unit 80 opens the first on-off valve 40B and opens the second on-off valve 45A. In addition, the control unit 80 operates the pressure transfer pump of the water source 50 and the vacuum pump of the smoke exhaust unit 60. As a result, as indicated by a thick line in FIG. 4, extinguishing water and smoke flow.

Although FIG. 1 shows sections A and B of a building, there are actually three or more sections. In the case where a fire occurs in one of the many compartments, the smoke in the other compartments will be described with reference to FIG.
FIG. 5 is a schematic view for explaining the smoke emission in another section when a fire occurs from one section of a building. As shown in FIG. 5, it is assumed that there are a large number of sections A to J in the building. Here, it is assumed that a fire has occurred in section C. Then, the control unit 80 extinguishes the section C with fire extinguishing water by the head section 10C, and at the sections B, D, G, H, I adjacent to the section C, through the head sections 10B, 10D, 10G, 10H, 10I. Exhaust smoke. As a result, even if smoke leaks from the section C where the fire occurred into the sections B, D, G, H, I, the sections B, D, G, H, I are exhausted, so the sections B, D, G , H, I will be evacuated smoothly.
Further, in the building shown in FIG. 5, the sections A to J, which are rooms, face each other across the corridor 5, but the head unit 10K is also installed in the corridor 5 when the predetermined installation condition is satisfied. In such a building, for example, when a fire occurs in the section C, the control unit 80 also causes the head section 10K of the corridor 5 located near the section C to emit smoke.

  In the above description, as described in FIG. 3, when a fire occurs in section A, the control unit 80 sprays extinguishing water in section A and sucks smoke in section B, but It is not limited to this. For example, when a fire occurs in the section A, the control unit 80 may sequentially switch between the sprinkling of fire extinguishing water to the section A and the suction of smoke in the section A to perform both. As a result, it is possible to extinguish the section A and remove the smoke generated in the section A, and it is possible to suppress the smoke from flowing into the section B.

(Operation example of sprinkler equipment)
An operation example of the sprinkler facility 1 when a fire occurs in a building will be described with reference to FIG.
FIG. 6 is a flowchart for explaining an operation example of the sprinkler installation 1 for the sections A and B when a fire occurs. Here, it is assumed that a fire occurs in the section A and a part of smoke caused by the fire goes around the section B.

  First, the sensor 20A installed in the section A senses a fire generated in the section A (step S102). When the sensor 20A senses a fire in the section A, the sensor 20A outputs a fire signal indicating that a fire has occurred in the section A to the control unit 80.

  Next, the control unit 80 receives a fire signal from the sensor 20A by the receiver (step S104). Thus, the control unit 80 can identify the section A in which the fire has occurred among the plurality of sections of the building.

  Next, the control unit 80 controls the opening and closing of the first on-off valves 40A and 40B and the second on-off valves 45A and 45B based on the received fire signal. Before receiving the fire signal, the first on-off valves 40A and 40B and the second on-off valves 45A and 45B are all closed. When the control unit 80 receives a fire signal from the sensor 20A, the control unit 80 opens the first on-off valve 40A of the extinguishing water passage 31A and the second on-off valve 45B of the smoke passage 32B (step S106). At this time, the first on-off valve 40B and the second on-off valve 45A are maintained in the closed state.

  Next, the control unit 80 operates the pressure feed pump of the water source 50 and the vacuum pump of the smoke exhaust unit 60 (step S108). Thereby, the extinguishing water sent by the pumping pump flows to the head unit 10A via the extinguishing water flow passage 31A and the common flow passage 30A, and is sprayed to the section A (see FIG. 3). In addition, the smoke in the section B is sucked from the head unit 10B by the vacuum pump, and is exhausted from the smoke exhaust unit 60 via the common flow passage 30B and the smoke flow passage 32B.

That is, water spray of fire extinguishing water to section A and suction of smoke from section B adjacent to section A are performed together (step S110). As a result, it is possible to extinguish the compartment A and to smoke the smoke which has entered the compartment B. Exhausting the compartment B in this way makes it easier for people in the compartment B to evacuate when a fire occurs in the compartment A.
The sprinkling of fire extinguishing water into the above-mentioned section A and the suction of smoke from the section B are continuously performed until the section A is extinguished and safety is secured.

(Effect in the first embodiment)
According to the first embodiment, each of the head portions 10A and 10B provided in the compartments A and B sprinkles fire extinguishing water to the compartments A and B or sucks smoke from the compartments A and B. In addition, the control unit 80 controls the first on-off valve 40A, 40B and the second on-off valve 45A, 45B to flow one of the extinguishing water and the smoke to the common flow path 30A, 30B, and the head unit 10A. 10B, whether to extinguish fire water or to suck smoke from the head portions 10A and 10B.
According to the above-described configuration, by the opening and closing control of the first on-off valve 40A, 40B and the second on-off valve 45A, 45B, one common flow path and the head portion do not flow firewater and smoke into separate flow paths. Sprinkling of fire water and smoke can be done to one section. This simplifies the configuration of the piping for flowing extinguishing water and smoke.
Further, according to the first embodiment, when a fire occurs in the section A, the section A is extinguished, and the section B adjacent to the section A is exhausted so as to turn from the section A to the section B. It can exhaust the smoke properly. Thereby, it is possible to suppress that the compartment B is full of smoke, and it is possible to secure an evacuation time of the person who was in the compartment B.

Second Embodiment
In the first embodiment, the first on-off valves 40A and 40B are provided in the extinguishing water flow passages 31A and 31B, and the second on-off valves 45A and 45B are provided in the smoke flow passages 32A and 32B. On the other hand, in the second embodiment, three-way valves are provided at the branching portions of the extinguishing water flow channels 31A, 31B and the smoke flow channels 32A, 32B.

  FIG. 7 is a schematic view for explaining a schematic configuration of the sprinkler installation 1 according to the second embodiment. As shown in FIG. 7, a three-way valve 70A is provided at the branch of the extinguishing water channel 31A and the smoke channel 32A, and a three-way valve 70B is provided at the branch of the extinguishing water channel 31B and the smoke channel 32B. The three-way valve 70A has three openable / closable openings connected to the common flow path 30A, the extinguishing water flow path 31A, and the smoke flow path 32A. Similarly, the three-way valve 70B also has three openable / closable openings connected to the common flow passage 30B, the extinguishing water flow passage 31B, and the smoke flow passage 32B.

  Then, the control unit 80 controls the three openings of the three-way valve 70A, 70B to make the heads 10A, 10B sprinkle water with extinguishing water, or from the heads 10A, 10B as in the first embodiment. You can switch whether to inhale smoke. In FIG. 7, the three openings of the three-way valve 70A are opened and closed so that extinguishing water is directed from the water source 50 to the head portion 10A. Similarly, the three openings of the three-way valve 70B are also opened and closed so that the smoke sucked by the head unit 10B is directed to the smoke exhaust unit 60.

  In the case of the second embodiment, compared to the first embodiment in which the opening and closing of the first on-off valve 40A and the second on-off valve 45A are controlled for one section A, three directions for one section A Since only the valve 70A needs to be controlled, the number of control targets can be reduced. In addition, by reducing the number of valves, the piping configuration can be further simplified.

Third Embodiment

The head portions 10A and 10X are disposed apart at the ceiling of the section A. Then, when a fire occurs in the section A, the control unit 80 causes the head unit 10A to spray extinguishing water and causes the head unit 10X to suck smoke. For example, the control unit 80 causes fire extinguishing water to be sprayed from the head unit 10A close to the fire occurrence location, while drawing smoke from the head unit 10X far from the fire occurrence location. The control unit 80 controls the head unit 10A to spray extinguishing water and sucks smoke from the head unit 10X for a predetermined time, and then sucks smoke from the head unit 10A and extinguishes water to the head unit 10X. Water may be sprayed. Thereby, the whole of the section A can be extinguished and exhausted effectively.

  According to the third embodiment, by controlling the plurality of head portions provided in one section, it is possible to appropriately perform the fire extinguishing and the smoke according to the occurrence of the fire in the section.
