Description

  The present invention relates to a fire extinguishing apparatus in which a water discharge nozzle for fire extinguishing is stored in a storage box.

  As a conventional fire extinguishing apparatus that is exposed or installed on the wall surface of a protective compartment, a fire extinguishing apparatus in which a water discharge nozzle for fire extinguishing is housed in a storage box is known. In such a fire extinguisher, the opening of the storage box is closed by a door during normal times so that the aesthetic appearance in the protective compartment is not impaired. Then, when a fire occurs, the fire-extinguishing water discharge nozzle turns and discharges water from the water discharge nozzle exposed from the opening of the storage box, thereby extinguishing the fire.

  As such a conventional fire extinguishing apparatus, for example, “a fire extinguishing box has a revolving door, and the revolving door is fixed to a rotation support shaft to which the water discharge head is fixed, and the flame detector and the infrared ray are fixed. A linear sensor is fixed to the movable water discharge head, and is disposed on the side of the water discharge head, and is disposed outside the water spray area inside the turning trajectory circle of the revolving door, and the direction thereof The direction is different from the direction of the axial center of the water discharge head, and when searching for a fire source, the fire source is searched with the infrared sensor while turning the water discharge head at a high speed. Oriented in the direction of the fire source, stopped turning while catching the fire source while turning in the vicinity of the fire source direction at a speed slower than the turning speed at the time of exploration of the infrared sensor, and then further turning the water discharge head, Sensor stop position In that water discharge towards the fire source "as that (see Patent Document 1) has been proposed.

Japanese Patent No. 4006722 (paragraph 0006, FIG. 1)

  In a conventional fire extinguishing apparatus (for example, Patent Document 1), a door that closes an opening of a storage box is attached to a rotating shaft (rotating support shaft) (hereinafter, the door attached to the rotating shaft is also referred to as a rotating door). . That is, the revolving door is also turned inside the storage box by the rotation of the rotation shaft. For this reason, when the revolving door is deformed by an external force or the like, there is a problem that when the revolving door is rotated, a device or the like provided inside the storage box may be damaged.

  Moreover, the conventional fire extinguishing apparatus requires a driving force that exceeds the large air resistance acting on the revolving door when the revolving door having a size close to the width of the fire extinguishing apparatus (storage box) is swung at high speed. For this reason, the subject that power consumption will increase also occurred.

  The present invention has been made to solve at least one of the above-described problems, and an object of the present invention is to provide a fire extinguishing apparatus capable of suppressing damage to equipment and the like provided in a storage box. .

  The fire extinguishing apparatus according to the present invention includes a rotating shaft, a fire-extinguishing water discharge nozzle provided on the rotating shaft, a storage box for storing the fire-extinguishing water discharge nozzle in a normal state, and a fire-extinguishing water discharge nozzle stored in the storage box. The fire extinguisher is provided with at least one door that closes the opening formed in the storage box in the state, and in the event of a fire, the water discharge nozzle for fire extinguishing is rotated by the rotation of the rotating shaft, and the water discharge nozzle for fire extinguishing is exposed from the opening. In the apparatus, at least one of the doors is rotatably connected to the storage box, and when the fire-extinguishing water discharge nozzle is exposed from the opening, the door connected to the storage box faces the outside of the storage box. Open.

  In the present invention, at least one of the doors closing the opening of the storage box is rotatably connected to the storage box. And when a rotating shaft rotates and the water discharge nozzle for fire extinguishing is exposed from an opening part, the door connected to the storage box opens toward the outer side of a storage box. For this reason, the turning range of the door in the storage box is reduced as compared with the conventional fire extinguishing apparatus. Therefore, even when the door is deformed by an external force or the like, it is possible to suppress damage to equipment or the like provided in the storage box.

Embodiment 1 FIG.
FIG. 1 is an external perspective view showing the front side of a fire extinguishing apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a plan view (cross-sectional view) showing the fire extinguishing apparatus. The fire extinguishing apparatus 100 shown in FIG.1 and FIG.2 has shown the state by which the opening part 1a formed in the front (front surface) of the storage box 1 was obstruct | occluded by the left door 2 and the right door 3. FIG. FIG. 2 is a cross-sectional view taken above the cam 11.
FIG. 3 is also an external perspective view showing the front side of the fire extinguishing apparatus according to Embodiment 1 of the present invention, and FIG. 4 is also a plan view (cross-sectional view) showing the fire extinguishing apparatus. The fire extinguishing apparatus 100 shown in FIG.3 and FIG.4 has shown the state which the opening part 1a formed in the front (front surface) of the storage box 1 opened. Further, FIG. 3 shows the fire extinguishing apparatus 100 in a state where the fire detection unit 30 is disposed on the front surface in order to facilitate explanation of the internal structure. FIG. 4 is a cross-sectional view taken below the cam 11.
Hereinafter, the fire extinguishing apparatus 100 according to the first embodiment will be described with reference to FIGS.

The storage box 1 of the fire extinguishing apparatus 100 has a substantially quadrangular shape in a front view, and has a substantially pentagonal shape with a front side protruding in a plan view. The interior of the storage box 1 is divided into an upper space and a lower space. An opening 1 a that communicates with the lower space and an opening 1 b that communicates with the upper space are formed on the front surface of the storage box 1. In a state where no fire signal is received (normal state), the opening 1 a is closed by the left door 2 and the right door 3. At this time, the left door 2 and the right door 3 are arranged so that these front walls and the front wall of the storage box 1 are substantially uniform. The right door 3 is rotatably connected to the storage box 1 by a hinge 3a provided at the top. The left door 2 is attached to a rotating shaft 10 which will be described later. That is, the right door 3 is a door that opens to the outside of the storage box 1 with the hinge 3a as a rotation center. The left door 2 is a revolving door that rotates together with the rotation shaft 10.
Further, the opening 1 b of the storage box 1 is closed by a fixed door 4.

  Note that “blocking” in the first embodiment means that it is substantially blocked. That is, a slight gap may be formed between the left door 2 and the right door 3 and the storage box 1. The shape of the storage box 1 is merely an example, and may be, for example, a substantially rectangular parallelepiped shape.

In the storage box 1 (more specifically, in the lower space of the storage box 1), a fire-extinguishing water discharge nozzle 21, a fire detection unit 30, and the like are stored.
The fire-fighting water discharge nozzle 21 is connected to the water supply flange 22 and is disposed along the inner wall of the left door 2 in plan view. The fire-extinguishing water discharge nozzle 21 is provided on the rotary shaft 10 that communicates from below the storage box 1 to the upper space. The fire-extinguishing water discharge nozzle 21 is composed of, for example, a plurality of nozzles having different water discharge distances.

The fire detection unit 30 according to the first embodiment includes a heat source exploration device 31 and a flame detection device 32. The heat source exploration device 31 includes an infrared linear sensor, for example, and is used to specify the direction of the fire source. The flame detection device 32 makes a flame determination by detecting CO ₂ resonance radiation and fluctuation generated by the flame. The heat source exploration device 31 and the flame detection device 32 are also provided on the rotary shaft 10 in the same manner as the fire-extinguishing water discharge nozzle 21.

  In the first embodiment, each of the fire-extinguishing water discharge nozzle 21, the heat source exploration device 31, and the flame detection device 32 is provided on the rotating shaft 10 so as to face different directions. Thereby, the storage space of the water discharge nozzle 21 for fire extinguishing, the heat source exploration apparatus 31, and the flame detection apparatus 32 can be made small, and the fire extinguishing apparatus 100 can be manufactured compactly.

The rotating shaft 10 is provided with a cam 11 that is a plate cam at a position that is the same height as the hinge 3a of the right door 3 in a front view. Moreover, the cam 11 is provided so that it may contact | abut on the hinge 3a, when the rotating shaft 10 rotates. That is, the hinge 3a and the cam 11 correspond to the cam mechanism of the present invention. The side surface shape of the cam 11 has, for example, two arc shapes with different radii, and the arc shapes with different radii are connected by a cam curve. In the state in which the right door 3 closes the opening 1a, the side surface, which is the radius on the small side of the cam 11, is in contact with the hinge 3a.
In the present embodiment, the hinge 3a is used as the cam receiving portion. However, a member other than the hinge 3a may be separately provided as the cam receiving portion. Further, in a state where the right door 3 closes the opening 1a, the side surface of the cam 11 may not be in contact with the hinge 3a.

The rotating shaft 10 is provided with a gear 12 at a position, for example, above the cam 11. The gear 12 is meshed with a gear 15 provided on the drive shaft of the motor 14. That is, the driving force of the motor 14 is transmitted to the rotary shaft 10 via the gear 15 and the gear 12 and the rotary shaft 10 rotates. In addition, the rotary shaft 10 is provided with an encoder 13 that measures the rotation angle of the rotary shaft 10.
The gear 12, the gear 15, the motor 14 and the encoder 13 are arranged in the upper space of the storage box 1. A control unit 50 that controls the motor 14 and the like is also stored in the upper space of the storage box 1.

<Description of operation>
Next, the operation of the fire extinguishing apparatus 100 configured as described above will be described. First, the opening / closing operation | movement of the right door 3 is demonstrated. Next, the fire extinguishing operation of the fire extinguishing apparatus 100 will be described.

(Door open / close operation)
FIG. 5 is an operation explanatory view of the cam mechanism according to Embodiment 1 of the present invention. This figure is the figure which looked at the right door 3 from the side. As described above, the side surface shape of the cam 11 has, for example, two arc shapes having different radii, and the arc shapes having different radii are connected by a cam curve (FIG. 2). For this reason, when the rotating shaft 10 is rotated in a direction in which the water discharge nozzle 21 for fire extinguishing is exposed from the opening 1a (counterclockwise direction in FIG. 2), the side surface portion which is the cam curve of the cam 11 and the hinge of the right door 3 3a contacts. Thereby, with rotation of the rotating shaft 10, the right door 3 is pushed upwards with the hinge 3a as a rotation center (opens to the outside of the storage box 1). When the rotary shaft 10 further rotates, the side surface portion having a larger radius of the cam 11 comes into contact with the hinge 3a. Thereby, the raising of the right door 3 stops.
In addition, the right door 3 is urged | biased in the direction which closes the right door 3 by coil spring etc. (not shown), for example. Thereby, the right door 3 can follow the cam 11 more reliably and can be prevented from being closed.

  That is, the positional relationship among the open / closed state of the right door 3 and the left door 2, the fire-extinguishing water discharge nozzle 21, the heat source exploration device 31, and the flame detection device 32 is as shown in FIGS. 6 to 14.

6-14 is explanatory drawing which shows the operation | movement transition of each unit in the fire extinguishing apparatus which concerns on Embodiment 1 of this invention. 6-14 is the figure which looked at the fire extinguishing apparatus 100 planarly.
In a state where the control unit 50 does not receive a fire signal (normal state), each unit of the fire extinguishing apparatus 100 is in the state shown in FIG. That is, the opening 1 a is closed by the left door 2 and the right door 3, and the fire-extinguishing water discharge nozzle 21, the heat source exploration device 31, and the flame detection device 32 are stored in the storage box 1.

When receiving the fire signal, the control unit 50 drives the motor 14 to rotate the rotating shaft 10 in the direction in which the fire-extinguishing water discharge nozzle 21 is exposed from the opening 1a (the counterclockwise direction in FIG. 6). Then, in the process of changing from the state shown in FIG. 6 to the state shown in FIG. 7, the side surface portion that is the cam curve of the cam 11 and the hinge 3 a of the right door 3 come into contact, and the right door 3 starts to open. In FIG. 7, the right end of the left door 2 that rotates together with the rotary shaft 10 is in a state of being sunk under the right door 3. At this time, the right door 3 is open to a position where it does not interfere with the left door 2.
The position of the fire-extinguishing water discharge nozzle 21 shown in FIG. 7 is the origin position of the fire-extinguishing water discharge nozzle 21, and the swivel operation is performed from this position. Further, the state where the heat source exploration device 31 is arranged at the origin position is a state shown in FIG.

When the rotating shaft 10 further rotates, the right door 3 further opens along with the rotating shaft 10. Further, the left door 2 is further lowered below the right door 3 (the state shown in FIG. 8).
When the rotating shaft 10 further rotates, the side surface portion having a larger radius of the cam 11 comes into contact with the hinge 3a, and the right door 3 stops (the state shown in FIG. 9).

  The fire extinguishing apparatus 100 needs to rotate the rotating shaft 10 until the heat source exploration apparatus 31 comes near the right end of the opening 1a in order to detect a fire. For this reason, until the heat source exploration device 31 comes near the right end of the opening 1a (from the state shown in FIG. 9 to the state shown in FIG. 14), the right door 3, the left door 2, the fire-extinguishing water discharge nozzle 21, and the heat source The right door 3 continues the open state shown in FIG. 9 so that the exploration device 31 and the flame detection device 32 do not interfere with each other. That is, the state in which the fire-extinguishing water discharge nozzle 21 is sunk under the right door 3 (the state shown in FIGS. 10 to 12), and the flame detection device 32 is squeezed in under the right door 3 (the state shown in FIGS. 12 to 13). And in the state (state shown in Drawing 12 thru / or Drawing 14) where heat source exploration device 31 slips under right door 3, right door 3 continues the opened state.

By opening and closing the right door 3 in this way, the turning range of the door in the storage box 1 is reduced as compared with the conventional fire extinguishing apparatus. More specifically, in the conventional fire extinguishing apparatus, the door portion corresponding to the right door 3 also rotates together with the rotation shaft. In the fire extinguisher 100 according to the first embodiment, the right door 3 does not rotate together with the rotary shaft 10, so the turning range of the right door 3 in the storage box 1 is reduced.
In addition, by opening and closing the right door 3 in this way, when the rotary shaft 10 is rotated, the air resistance of the right door 3 is reduced as compared with the conventional fire extinguishing device.

(Fire fighting operation)
Next, the fire extinguishing operation of the fire extinguishing apparatus 100 will be described.
When receiving the fire signal, the control unit 50 rotates the rotary shaft 10 at a high speed and searches for the heat source by the heat source search device 31. Then, when the direction of the heat source is specified, the control unit 50 stops the rotation of the rotary shaft 10 and stores the direction of the heat source based on the measurement result of the encoder 13.
Thereafter, the control unit 50 rotates the rotary shaft 10 so that the flame detection device 32 is oriented in the heat source direction. When the flame detection device 32 comes to a position that points in the heat source direction, the control unit 50 stops the rotation of the rotary shaft 10. Then, the control unit 50 determines whether or not the heat source is flame by the flame detection device 32.
When it determines with a heat source being a flame, the control unit 50 rotates the rotating shaft 10 so that the fire-extinguishing water discharge nozzle 21 is oriented in the heat source direction. Then, the control unit 50 discharges water from the fire-extinguishing water discharge nozzle 21 to extinguish the fire.

  At this time, the positional relationship among the right door 3, the left door 2, the fire-extinguishing water discharge nozzle 21, the heat source exploration device 31, and the flame detection device 32 is any of the processes operating from the state shown in FIG. 6 to the state shown in FIG. 14. This is the positional relationship.

As described above, in the fire extinguishing apparatus 100 configured as described above, the right door 3 is rotatably connected to the storage box 1. When the rotary shaft 10 rotates, the right door 3 opens toward the outside of the storage box 1. For this reason, the turning range of the door in the storage box 1 is reduced as compared with the conventional fire extinguishing apparatus. Therefore, even when the left door 2 and the right door 3 are deformed by an external force or the like, it is possible to suppress breakage of equipment or the like provided in the storage box 1.
Moreover, in the fire extinguishing apparatus 100 configured as described above, the load (air resistance applied to the rotary door) when rotating the rotary shaft 10 is reduced as compared with the conventional fire extinguishing apparatus 100. For this reason, the power consumption of the motor 14 can be reduced.

  Further, since the right door 3 is opened and closed by the cam mechanism (cam 11 and hinge 3a), the right door 3 can be opened and closed in conjunction with the rotation of the rotary shaft 10. For this reason, the fire extinguishing apparatus 100 can be operated by the same control method as the conventional fire extinguishing apparatus.

In addition, although the fire extinguishing apparatus 100 according to the first embodiment uses the left door 2 as a revolving door, the left door 2 may have an outer opening structure similar to that of the right door 3.
FIG. 15 is a front external perspective view showing another example of the fire extinguishing apparatus according to Embodiment 1 of the present invention. FIG. 16 is a plan sectional view showing the fire extinguishing apparatus.
As shown in FIGS. 15 and 16, the left door 2 is rotatable to a storage box 1 (more specifically, a position above the opening 1 a) by a hinge (not shown), like the right door 3. It is connected to the. The left door 2 also has a structure in which, for example, the cam 11 and the hinge of the left door 2 are in contact with each other, and the left door 2 opens outward in conjunction with the rotary shaft 10.

When both the left door 2 and the right door 3 have an outward opening structure, there is no door turning range in the storage box 1. For this reason, even when the left door 2 and the right door 3 are deformed by an external force or the like, it is possible to further suppress the damage of the devices provided in the storage box 1. Moreover, since the load at the time of rotating the rotating shaft 10 further decreases, the power consumption of the motor 14 can be further reduced.
On the other hand, when only the right door 3 has an outward opening structure, the fire extinguishing apparatus 100 can be manufactured more easily than when both the left door 2 and the right door 3 have an outward opening structure. This is because it is difficult to synchronize the left door 2 and the right door 3 when both the left door 2 and the right door 3 are operated with a cam structure.

  In Embodiment 1, the opening 1a of the storage box 1 is closed by two doors (the left door 2 and the right door 3), but the number of doors closing the opening 1a is arbitrary. Further, for example, when the opening 1a of the storage box 1 is closed with three or more doors, the effect of the present invention can be obtained by making at least one of these doors an outer opening structure.

  In the first embodiment, the heat source exploration device 31 and the flame detection device 32 are provided as the fire detection unit 30, but this is an example of the fire detection unit 30. For example, the fire detection unit 30 may be configured by one of the heat source exploration device 31 and the flame detection device 32. In addition, the fire detection unit 30 may be provided on another rotating shaft other than the rotating shaft 10.

  Further, in the first embodiment, the door having the outward opening structure (for example, the right door 3) is opened by the cam structure, but the structure for opening the door having the outward opening structure may be other than the cam structure. For example, the door having the outward opening structure may be urged in the opening direction by a coil spring or the like, and the door having the outward opening structure may be closed by a stopper driven by a solenoid or the like. By driving the stopper, the door with the outward opening structure can be opened by the biasing force of the coil spring. At this time, the timing for driving the stopper may be before the rotation shaft 10 rotates, at the same time as the rotation of the rotation shaft 10 or after the rotation shaft 10 rotates. If the door with the outer opening structure and the unit (for example, the fire extinguishing water discharge nozzle 21 and the fire detection unit 30) provided on the rotary shaft 10 do not interfere with each other, the drive timing of the stopper is arbitrary.

Embodiment 2. FIG.
In the first embodiment, the door with an outward opening structure is opened and closed in the vertical direction. Not only this but the structure of opening and closing the door of an outward opening structure in the left-right direction is good. In the second embodiment, items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals.

  FIG. 17 is an external perspective view showing the front side of the fire extinguishing apparatus according to Embodiment 2 of the present invention, and FIG. 18 is a plan view (sectional view) showing the fire extinguishing apparatus. The fire extinguishing apparatus 100 shown in FIG.17 and FIG.18 has shown the state which the opening part 1a formed in the front (front surface) of the storage box 1 opened. Moreover, FIG. 17 has shown the fire extinguishing apparatus 100 of the state by which the fire detection part 30 is arrange | positioned in the front.

  The fire extinguishing apparatus 100 according to the second embodiment is configured such that the opening 1a is closed by the left door 2 and the right door 3 as in the first embodiment. However, the connection position between the right door 3 and the storage box 1 is different from that of the first embodiment. More specifically, the right door 3 has a right end portion rotatably connected to the storage box 1. In other words, the right door 3 is a door having an outward opening structure that opens and closes in the left-right direction. The left door 2 is a revolving door attached to the rotary shaft 10 as in the first embodiment.

  Also in the fire extinguisher 100 configured in this way, the turning range of the door in the storage box 1 is reduced as compared with the conventional fire extinguishing apparatus. Therefore, even when the left door 2 and the right door 3 are deformed by an external force or the like, it is possible to suppress breakage of equipment or the like provided in the storage box 1. Further, since the load (air resistance applied to the rotary door) when rotating the rotary shaft 10 is smaller than that of the conventional fire extinguishing apparatus 100, the power consumption of the motor 14 can be reduced.

Note that the fire extinguishing apparatus 100 according to the second embodiment may also be configured such that both the left door 2 and the right door 3 have an outward opening structure, as in the first embodiment.
FIG. 19 is a front external perspective view showing another example of the fire extinguishing apparatus according to Embodiment 2 of the present invention. FIG. 20 is a plan sectional view showing the fire extinguishing apparatus.
As shown in FIGS. 19 and 20, the left door 2 is rotatably connected to the storage box 1 (more specifically, the position that becomes the left end of the opening 1 a), like the right door 3.

  Thus, by making both the left door 2 and the right door 3 have an outwardly open structure, there is no door turning range in the storage box 1. For this reason, even when the left door 2 and the right door 3 are deformed by an external force or the like, it is possible to further suppress the damage of the devices provided in the storage box 1. Moreover, since the load at the time of rotating the rotating shaft 10 further decreases, the power consumption of the motor 14 can be further reduced.

Embodiment 3 FIG.
In the fire extinguishing apparatus configured as shown in the first embodiment or the second embodiment, a simulated fire source for confirming whether the heat source exploration apparatus 31 operates normally is the heat source exploration apparatus 31 or the like. May be provided separately. By implementing the present invention in such a fire extinguisher, further effects can be obtained. In Embodiment 3, items that are not particularly described are the same as those in Embodiment 1 or Embodiment 2, and the same functions and configurations are described using the same reference numerals.

FIG. 21 is a plan view (sectional view) showing a fire extinguishing apparatus according to Embodiment 3 of the present invention. FIG. 21 shows the fire extinguishing apparatus 100 in a normal state.
As shown in FIG. 21, a simulated fire source 31 a is provided in front of the heat source exploration device 31 in the direction of the heat source exploration device 31. The simulated fire source 31a is for confirming whether or not the heat source exploration device 31 operates normally, and is, for example, a heating wire or a halogen lamp.

  In the conventional fire extinguishing apparatus, the door that closes the opening 1a is a revolving door. Therefore, when the door is opened to check the operation of the heat source exploration apparatus 31, the heat source exploration apparatus 31 also rotates together with the rotation shaft 10. . For this reason, the directivity direction of the heat source exploration device 31 and the position of the simulated fire source 31a are shifted, and it is not easy to confirm the operation of the heat source exploration device 31.

  On the other hand, in the fire extinguishing apparatus 100 according to the third embodiment, since the right door 3 has an outward opening structure, even if the right door 3 is opened in order to check the operation of the heat source exploration apparatus 31, the heat source exploration apparatus 31. The position of does not change. For this reason, the operation check of the heat source exploration device 31 is facilitated.
