Description

The present invention provides a reduction in equipment costs and the convenience of maintenance, etc. for package-type automatic fire extinguishing equipment and similar forms of fire extinguishing equipment that can be installed in place of sprinkler equipment, etc. as defined in Article 12 of the Fire Service Act Enforcement Ordinance. It is a measure.

(1) Outline of fire extinguishing equipment The package type automatic fire extinguishing equipment is a fixed fire extinguishing equipment that detects heat, combustion products, etc. generated by a fire and automatically emits a fire extinguishing agent. Fire extinguishing equipment main body (receiver, fire extinguishing agent storage container, pressurized gas container, operating device, emergency power supply device) and equipment such as fire detector, discharge conduit, selection valve, discharge port and control wiring, piping (Discharge conduit) or the like is configured as shown in FIG.
The installed fire extinguishing equipment issues an alarm when one of the sensors (attaching two sensors with different detection methods) provided in the fire protection area is activated, and a receiver when both are activated Recognizes it as a fire signal and activates the fire extinguishing equipment body, and simultaneously opens the selection valves (all selection valves are normally closed) provided in the piping path leading to the detector alarm section to release the fire extinguishing agent in the fire section. It has a structure that discharges from the outlet.
In the case of FIG. 1, the fire extinguishing agent storage container is a plurality of containers due to the installation space.
The fire extinguishing agent for package-type automatic fire extinguishing equipment can be selected from water containing infiltrant etc., strengthening liquid, machine foam, and other types suitable for fire prevention objects, enabling early operation with a fire detector and effective quantitative extinguishing agent It is a system that extinguishes fire at the initial stage of a fire by discharging it into a protective compartment from the discharge port.

(2) Receiver (control panel)
The receiving device of the package type automatic fire extinguishing equipment is installed in all main bodies, and as an example of arrangement, its functional part is roughly divided into the following two parts as shown in FIG.

A main unit (part a)
Equipment that is installed in the main body functions and facilities such as receiving the electrical signal of the individual unit that monitors the fire in each protection zone, transmitting the operation of the main body, starting the main selection valve provided in the main pipe, emergency power supply, alarm, indicator light, etc. Control the part related to.
In the case of the receiving apparatus of FIG. 2, it corresponds to the upper part.

B. Individual unit (part b)
A control panel equipped with communication connection terminals such as sensors, district selection valves, etc. provided in each protection section and a fire display of each protection section, a plurality (for example, 30 lines) are arranged as shown in the lower part of FIG. Yes.

(3) The fire extinguishing agent held in one package-type automatic fire extinguisher main body operated for the combination of the configuration of the protective compartment and the fire extinguishing equipment main body radiates all to one protective compartment.
Assuming that the fire spreads to other sections, the installation standards for package-type automatic fire extinguishing equipment are, except for specific applications, “adjacent simultaneous radiation areas are fireproof performance according to the Building Standards Act Enforcement Ordinance or equivalent or better. The part that is not partitioned by a wall or the like having fire prevention performance should not be used. "
Fig. 5 shows an example of a building where equipment is installed. Even if the total floor area is small, package-type automatic fire extinguishing equipment is installed in 5 sections of 5 rooms and 3 sections of the corridor. In order to protect the area where the adjacent area is not fire-proofed with different main bodies, the fire-proof section cannot be configured with two units A and B. Therefore, the main body C is added regardless of the number of lines owned by the main body receiver 3 By installing the main body of the base and combining the sections composed of the main bodies A, B, and C so as not to be adjacent to each other as shown in FIG. It has become the standard to arrange.
Note that the protective capability of the main body in the case of FIG.

(4) Conventional Main Unit Installation Situation When three units are installed, main units each incorporating a receiving device are installed as shown in FIG. If there is no space for juxtaposition, there may be separate installations.
When the number of control lines of the receiving apparatus is 30 lines per unit, three units are 90 lines, and when there are few protective sections, many unnecessary empty lines are generated in the individual units as shown in FIG.
This figure shows an example of using a receiving device when three main units are installed on a fire protection object with 25 protective zones, and 65 of the 90 lines do not use individual units. bad.

JP 7-79849

(1) To provide a low-cost fire extinguishing facility by improving the usage form of the inefficient receiving device as shown in FIG. 3 that occurs in a fire prevention object having a small total floor area.

(2) To enable centralized monitoring without receiving devices that are also fire monitoring devices dispersed.

(1) Combining a “master unit” with a built-in receiver as shown in FIG. 4 and a “slave unit” mainly composed of a medicine storage container that is activated by a “master unit” signal without being equipped with a receiver. Use a possible fire extinguishing system.
The reception of the sensor signal, the operation of the main body, the selection valve, etc. are all controlled by the receiving device of the “master unit”, and the “slave unit” is activated by receiving the actuation signal transmitted by the “master unit”. In the “Slave unit” containment box, there is a drug storage container and a slave unit start panel for receiving the “Master unit” signal to start the equipment inside the slave unit. A gas container and its operating device, and an operating device for opening the container valve of the fire extinguishing agent storage container if equipped with a pressure accumulation type. The receiving device of the “master unit” distributes the “master unit” itself and the “plurality of slave units” within the range of the controllable number of lines, and controls devices provided in each protection section.

(2) As a mechanism for the receiver of the master unit to control the slave unit, not only the electrical signal shown in FIG. 4 but also a starter that starts the operating device from the master unit to the slave unit actuating device as shown in FIG. There are also a method of supplying gas and a method of starting a gas pressure actuating operation device by starting a starting gas provided in each child device by an electric signal of the parent device as shown in FIG.

(3) The structure is such that the number of individual units of the receiving device can be easily increased or decreased as necessary.

A description will be given by comparing an installation example of a system composed of a “conventional type” in which all main bodies are equipped with a receiving device, a “master unit”, and a “slave unit”.
As an example of the case where the total floor area of the fire protection object to be installed is relatively small, in order to configure 25 protection zones and adjacent zones that are not fire protection zones with different main bodies, 3 main bodies (3 systems) The installation examples of the main body are compared in the embodiments of the inventions of claims 1 and 3 on the assumption that the installation is necessary.

(1) Arrangement of Conventional Type FIG. 1 is an arrangement diagram in which three conventional types are installed, each having a receiving device in the main body storage box.
