(Embodiment 1)
FIG. 1 is a schematic diagram of a cable tray fire extinguishing system 60 according to Embodiment 1. FIG. As shown in FIG. 1, in the cable tray fire extinguishing equipment 60 according to Embodiment 1, a container valve is attached to the upper portion of the extinguishing agent storage container 1 . The extinguishing agent storage container 1 is supported by a container support body 15 .

The container valve 19 is connected to a copper pipe 25 for extinguishing agent discharge, a sensing tube 24 , a sensing tube pressure switch 4 and a storage container pressure switch 3 . The sensing tube pressure switch 4 is not limited to being directly connected to the container valve 19, and may be connected in the middle of the sensing tube 24 (in the vicinity of the pressure gauge).

The inside of the sensing tube 24 is always pressurized. A cable tray 31 is installed in a factory, building, power plant, or the like. The cable tray 31 is tubular, and cables are provided therein. Cable tray 31 is covered with flame-retardant sheet 32 . The flame-retardant sheet 32 is fixed to the cable tray 31 with a fixing band 33 . A stainless steel band is wound around the cable tray 31 at the same position as the fixing band 33 to prevent the flame-retardant sheet 32 from hanging down into the cable tray.

A sensing tube 24 is provided within the cable tray 31 . The sensing tube 24 may or may not be in contact with the cable. A copper pipe 25 for extinguishing agent discharge is provided in the cable tray 31 . A fire extinguishing agent discharging injection nozzle 34 is attached to the fire extinguishing agent discharging copper pipe 25 .

The extinguishing agent storage container 1 contains, for example, FK-5-1-12, which is a halide extinguishing agent. This agent is pressurized by nitrogen in the extinguishing agent storage container 1 . This nitrogen is supplied to the sensing tube 24 via the sensing tube pressure switch 4 . When nitrogen is supplied into the sensing tube 24 at the time of installation, if nitrogen is introduced from the extinguishing agent storage container 1, the nitrogen in the extinguishing agent storage container 1 will decrease. You can fill it inside.

The heat of the fire causes the sensing tube 24 to melt and the pressure within the sensing tube 24 to drop.

When the pressure in the sensing tube 24 decreases, the container valve 19 operates, and the extinguishing agent (FK-5-1-12) is discharged from the extinguishing agent discharging injection nozzle 34 in the cable tray 31 through the extinguishing agent discharging copper pipe 25. is emitted.

When the pressure in the sensing tube 24 drops, the sensing tube pressure switch 4 is activated and a transfer signal is output.

The cable tray fire extinguishing equipment 60 also has a "function of discharging a fire extinguishing agent in response to an electrical activation signal" and a "function of monitoring pressure". The pressure status is displayed on site and transmitted to a monitoring room or the like. A monitoring room or the like has a panel for collecting information, and a panel for displaying the pressure state (pressure monitoring control panel) is required at the site in the same number as the container supports 20 (cylinder racks). In order to reduce the work load at the site, the structure is such that a display unit 14 as a pressure monitoring control panel is attached in advance to the side surface of the container support 20 . If the container support 20 and the display part 14 are separated, construction of the display part 14 and construction of wiring/conduits from the display part 14 to the container support 20 are separately required. Earthquake resistance verification is also required for construction. By integrating these, the construction load at the site will be reduced.

The container support main body 15 is mainly composed of steel square pipes and angle members. The container support main body 15 is constructed by welding steel materials. It has sufficient strength to hold a plurality of extinguishing agent storage containers 1 .

A fire extinguishing agent storage container 1 constituted by a cylinder stores a liquid extinguishing agent such as FK-5-1-12. Although three extinguishing agent storage containers 1 are provided in parallel in this embodiment, more or fewer extinguishing agent storage containers 1 may be provided.

A container valve of the fire extinguisher storage container 1 is connected to a copper pipe connection joint 6 by a flexible tube 2 . As a result, the extinguishing agent in the extinguishing agent storage container 1 is supplied to the copper pipe connection joint 6 via the flexible tube 2 .

The pressure in the sensing tube 24 is constantly monitored, and when this pressure drops, the sensing tube pressure switch 4 operates and a transfer signal is output. The transfer signal is transmitted to the monitoring room or the like.

Based on these transfer signals, it is possible to recognize that a fire has occurred in a monitoring room or the like.
The container fixture 5 has a function of engaging with the container support main body 15 to hold the extinguishing agent storage container 1 . A screw thread is provided on the outer peripheral surface of the end portion of the container fixing bracket 5 , and the container fixing bracket 5 can be fixed to the container support main body 15 by screwing a nut onto this screw thread.

The copper tube connection joint 6 is attached to the container support body 15 . The copper pipe connection joint 6 is interposed between the flexible tube 2 and the extinguishing agent discharge copper pipe 25 and is airtightly connected thereto. A fire extinguishing agent flows through the copper pipe connection joint 6 .

A sensing tube 24 is connected to the sensing tube filling joint 11 . The sensing tube filling joint 11 is supplied with nitrogen from the extinguishing agent storage container 1 . The sensing tube fill fitting 11 is attached to the container support body 15 .

The sensing tube solenoid valve 12 is attached to the container support main body 15 . A sensing tube pressure reduction pressure switch 13 is connected to the sensing tube solenoid valve. Nitrogen gas (fluid) in the fire extinguisher storage container 1 is sent to the sensing tube 24 via the sensing tube pressure reduction pressure switch 13 , the sensing tube solenoid valve 12 , and the sensing tube filling joint 11 .

A display portion 14 is attached to the container support main body 15 . The display is the remote activation/pressure monitoring system control panel. The display unit 14 displays whether the pressure of each of the plurality of sensing tubes 24 is normal or decreased. Display item 14a in FIG. 7 indicates, for example, the pressure of the sensing tube. The display unit 14 further displays whether or not the pressure in each of the multiple extinguishing agent storage containers 1 is normal and the extinguishing agent (FK-5-1-12) can be discharged.

The container support 20 includes a container support main body 15 that holds the fire extinguishing agent storage container 1 that supplies fluid to the sensing tube 24 that melts due to the heat of the fire, and a fire extinguishing agent storage provided in the container support main body 15. and a display unit 14 for displaying at least one of the pressure in the extinguishing agent container 1 and the pressure in the sensing tube 24 supplied from the extinguishing agent storage container 1 .

(Embodiment 2)
FIG. 8 is a schematic diagram of the container support 20 according to the second embodiment. In the container support 20 according to Embodiment 2, the extinguishing agent storage container 1 is sandwiched between a pair of container restraining devices 105 and 106 . Through holes are provided in the container restraining devices 105 and 106, and fixing bars 107 are inserted into the through holes.

Both ends of the fixing bar 107 are threaded and each end is inserted into a through hole. Nuts 108 are screwed on both ends. The contact of the nuts with the container restraining devices 105 and 106 can prevent the pair of container restraining devices 105 and 106 from moving away from each other.

By reducing the distance between the nuts 108 at both ends of the fixing bar 107, the distance between the container restraining devices 105 and 106 can be reduced, and the extinguishing agent storage container 1 can be positioned by the container restraining devices 105 and 106. can do. The container restraining devices 105 and 106 are held by the container support body 15 respectively.

Fixing bars 107 are provided at both ends in the direction in which the plurality of fire extinguishing agent storage containers 1 are arranged in a cross section perpendicular to the longitudinal direction of the plurality of fire extinguishing agent storage containers 1 . Container restraint devices 105 and 106 are arranged in the space surrounded by the container support body 15 shown in FIGS.

Since the fixing bar 107 has a linear shape between the nuts 108 on both ends, the fixing bar 107 is not easily deformed even if a large tensile stress is applied to the fixing bar 107 . As a result, the earthquake resistance of the container support 20 can be improved.

That is, the container support 20 includes a pair of container restraining devices 105 and 106 that hold the extinguishing agent storage container 1, and a pair of container restraining devices 105 and 106 interposed between the pair of container restraining devices 105 and 106. 106 are prevented from moving away from each other, and a fixing bar 107 is provided as a metal rod-shaped member that receives a tensile stress between the pair of container restraining devices 105 and 106 .

A portion of the fixing bar 107 that receives a tensile stress between the pair of container restraining devices 105 and 106 has a linear shape.

FIG. 9 is a schematic diagram of a container support 20 of a comparative example. 10 is a cross-sectional view taken along line XX in FIG. 9. FIG. FIG. 11 is a cross-sectional view of a deformed fixation bar 107. FIG.

As shown in these figures, the tip 109 of the fixing bar 107 according to the comparative example is bent. The bent portion is inserted into the through hole 105h of the container restraint device 105. As shown in FIG. Therefore, if a large force is applied to the fixing bar 107, the bent tip 109 may be deformed and detached from the through hole 105h. The structure of FIG. 8 does not cause such a problem.

(Embodiment 3)
FIG. 12 is a schematic diagram of container support 20 according to the third embodiment. As shown in FIG. 12, the container restraining device 105 according to Embodiment 3 and the extinguishing agent storage container 1 are in contact at points 1a and 1b. The container restraining device 106 and the extinguishing agent storage container 1 are in contact at points 1c and 1d. Since the fire extinguisher storage container 1 is pressed at four points in this way, the fire extinguisher storage container 1 is constrained in the front, rear, left and right directions. As a result, the rigidity of the container support main body 15 is improved. Tightening management of the container restraint devices 105 and 106 does not greatly affect the rigidity of the container support main body 15 . The extinguishing agent storage container 1 is cylindrical, and the extinguishing agent storage container 1 is filled with the extinguishing agent.

FIG. 13 is a schematic diagram of a container support 20 of a comparative example. As shown in FIG. 13, the container restraining device 105 according to the comparative example and the extinguishing agent storage container 1 are in contact at point 1a. The container restraining device 106 and the extinguishing agent storage container 1 are in contact at point 1c. Since the fire extinguishing agent storage container 1 is held down by two points in this way, the fire extinguishing agent storage container 1 is restrained in the front and rear direction, but can move left and right. Therefore, the rigidity of the container support main body 15 is inferior. Furthermore, the tightening management of the container restraint devices 105 and 106 affects the rigidity of the container support main body 15 .

The container support 20 includes a pair of container restraining devices 105 and 106 that hold the fire extinguishing agent storage container 1, and the pair of container restraining devices 105 and 106 in a cross section perpendicular to the longitudinal direction of the extinguishing agent storage container 1 (FIG. 12). At least one of the devices 105 and 106 contacts the extinguishing agent storage container 1 at two or more points. Preferably, both container restraining devices 105, 106 contact the extinguishing agent storage container 1 at two or more points in the cross section. If the container restraining devices 105 and 106 come into contact with the extinguishing agent storage container 1 at many points, the support of the extinguishing agent storage container 1 is unstable considering manufacturing errors (variation in outer diameter) of the extinguishing agent storage container 1. may become On the other hand, in the structure of FIG. 12, since the fire extinguishing agent storage container 1 does not move in the front, back, left, and right directions, the rigidity can be maintained with a weaker steel size.
